Description

Steel plate cutting device and cutting process thereof

Technical Field

The present invention relates to the technical field of steel plate cutting, and in particular to a steel plate cutting device and a cutting process thereof.

Background Art

Steel plate cutting is an important process in industrial production and is widely used in many fields such as machinery manufacturing, construction, and bridge construction. There are many ways to cut steel plates to meet the needs of different projects. After cutting, the steel plate needs to be polished. After polishing, a large amount of debris is attached to the surface of the steel plate. If the debris is not cleaned in time, when multiple steel plates are stacked together, the surface of the steel plate will be scratched and damaged.

For example, the stainless steel plate cutting equipment provided by the authorization announcement number CN11 7817368B, after the side of the stainless steel plate is polished, the descending cylinder is repeatedly started again to make the mounting frame rise, so that the polished stainless steel plate and the wiping plate are on the same parallel line, and the pushing cylinder is continued to be started to send the stainless steel plate into the interior of the two cleaning plates. Due to the action of the reset spring, the two cleaning plates wipe the polished stainless steel plate and clean the excess debris; through the descending cylinder, the mounting frame, the fixed frame cooperates with the wiping plate and the two cleaning plates, and by adjusting the height of the overall mounting frame and the inclination of the flip plate, the debris on the side of the cut stainless steel plate can be wiped, so as to avoid the adhesion of debris to the chamfered stainless steel plate and achieve the purpose of automatic cleaning.

It has major disadvantages: during use, the cleaning plate does not fully cover the upper and lower surfaces of the steel plate. During cleaning, the upper and lower surfaces of the steel plate cannot be fully cleaned, and the cleaning effect is poor, which causes the surfaces of multiple steel plates to be damaged during the stacking process; at the same time, the cleaning plate is located below the grinding disc. During the grinding process of the grinding disc, debris will fall onto the cleaning plate, causing scratches on the cleaning plate when cleaning the debris on the surface of the steel plate.

A cutting process of a steel plate cutting device comprises the following steps:

S 1. Place the steel plate to be cut on the guide plate 1, and the moving assembly 1 works. The internal cylinder 4 is extended and retracted so that the steel plate is located between the clamping cylinders in the clamping frame. The steel plate is clamped by the clamping cylinders to assist in the movement of its position.

S2. When the cutting position reaches the gap between the guide plate 1 and the guide plate 2, the laser cutter cuts the steel plate by extending and retracting the cylinder 1. During the cutting process, the electric slide 2 drives the cylinder 1 to move, thereby assisting in completely cutting the steel plate.

S3. After the cutting is completed, the rotating motor drives the grinding wheel to rotate. The steel plate is clamped by the clamping cylinder and the cylinder four is extended and retracted. In coordination with the movement of the electric slide table one, the cutting part of the steel plate is extended between the two grinding wheels to completely grind the steel plate. At the same time, the height of the grinding wheel can be adjusted by the cylinder two.

S4. After the grinding is completed, the cylinder 2 drives the fixed plate to descend, so that the steel plate can be placed in the upper scraper and the lower scraper. The upper scraper can be adjusted in height by the cylinder 3 to clamp the steel plate. The steel plate is pushed backward by the clamping of the moving component 1. During the pushing process, the upper scraper and the lower scraper scrape off the debris attached to the surface of the steel plate. During the scraping process, the debris slides down through the upper side of the inclined fixed frame. At the same time, when the steel plate extends out of the cleaning component, the moving component 2 on the other side clamps it through the internal clamping cylinder and pulls it out;

S5. After cleaning, the steel plate is placed on the conveyor belt by moving component 2 and transported; the steel plate is cut and polished and cleaned by this reciprocating motion.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

First, it can improve the cleaning effect of debris attached to the surface of the steel plate. The upper scraper and the lower scraper fully cover the surface of the steel plate, effectively preventing the existence of cleaning blind spots, and improving cleaning efficiency and cleaning quality; reduce scratches and damage, and completely clean the surface of the steel plate, which can effectively prevent scratches and damage to the surface of the steel plate during the subsequent stacking process, reduce the risk of scratches and damage, and protect the appearance and performance of the stainless steel plate; improve work efficiency, and be able to complete more comprehensive cleaning work at one time, reducing cleaning time and labor costs, and improving overall work efficiency; at the same time, installing the upper scraper and the lower scraper above the grinding wheel can effectively prevent debris from falling on the upper scraper and the lower scraper due to gravity during the grinding process, causing scratches to the steel plate placed later;

Secondly, in the process of cleaning the steel plate, the debris in front of the upper scraper can slide to both sides through the V-shaped upper scraper, which can effectively prevent the accumulation of debris and make it difficult to clean the debris. At the same time, the trapezoidal interception structure can effectively prevent the debris from crossing the upper scraper and falling back on the steel plate, thereby improving the cleaning efficiency and cleaning effect.

Thirdly, in the process of cleaning the debris on the steel plate by the upper scraper, the upper electromagnets and the lower electromagnets at different positions are controlled to be energized, and the impact rod is adsorbed, so that the impact rod impacts the upper scraper and the steel plate at different positions. During the impact, the upper scraper and the steel plate will vibrate, and the vibration of the upper scraper will disperse the debris accumulated in front. At the same time, when the steel plate vibrates, the debris attached to its surface will be vibrated, and the debris will be more dispersed and will not accumulate in one place.

Fourthly, the cavity above the separation membrane can be inflated by an air pump to tilt the impact rod. The inflation amount of the air pump can control the degree of inclination of the impact rod. After the tilted impact rod is adsorbed and powered off by the upper electromagnet or the lower electromagnet, the impact rod will collide with the bottom of the upper scraper multiple times due to the elasticity of the connection, thereby improving the dispersion effect. At the same time, during the repeated swinging process, multiple jets can be sprayed through cleaning pipes one and two to dredge and clean the debris accumulated in front of the upper scraper, thereby improving the cleaning effect.

Compared with the prior art, the cleaning effect of debris attached to the surface of the steel plate can be improved. The upper scraper 410 and the lower scraper 420 fully cover the surface of the steel plate, effectively preventing the existence of cleaning blind spots, and improving the cleaning efficiency and cleaning quality; reducing scratches and damage, and completely cleaning the surface of the steel plate can effectively prevent scratches and damage to the surface of the steel plate during subsequent stacking, reduce the risk of scratches and damage, and protect the appearance and performance of the stainless steel plate; improve work efficiency, and be able to complete more comprehensive cleaning work at one time, reducing cleaning time and labor costs, and improving overall work efficiency; at the same time, the upper scraper 410 and the lower scraper 420 are installed above the grinding wheel 360, which can effectively prevent debris from falling on the upper scraper 410 and the lower scraper 420 due to gravity during the grinding process, causing scratches to the steel plate placed later.

Embodiment 2: When the embodiment 1 is in use, the debris attached to the surface of the steel plate is cleaned by the installed upper scraper 410. During the scraping process, if there are a lot of debris, the debris will accumulate in front of the upper scraper 410, making it difficult to clean the debris, and the debris will pass over the upper scraper 410 and fall back on the steel plate, resulting in cleaning failure, requiring multiple cleanings. At the same time, when the steel plate moves between the upper scraper 410 and the lower scraper 420 at a fast speed, the debris will be hit, causing it to pass over the upper scraper 410 and fall back on the steel plate. Based on this, the solution of the embodiment 1 is improved, as shown in Figures 6 and 7:

The upper scraper 410 is V-shaped, and the tip of the V-shaped upper scraper 410 faces the second guide plate 140;

The upper scraper 410 is in the shape of an inverted right-angled trapezoid.

When the upper scraper 410 cleans the upper side of the steel plate, the debris accumulated in front of the movement can slide down along the side through the inclined upper scraper 410. At the same time, the right-angled trapezoidal upper scraper 410 can intercept the lifted debris during the process of scraping the steel plate debris to prevent it from passing over the upper scraper 410 and falling back onto the cleaned steel plate surface.

During the process of cleaning the steel plate, the debris located in front of the upper scraper 410 can slide to both sides through the V-shaped upper scraper 410, which can effectively prevent accumulation and make it difficult to clean the debris. At the same time, the trapezoidal interception structure can effectively prevent the debris from crossing the upper scraper 410 and falling back on the steel plate, thereby improving the cleaning efficiency and cleaning effect.

Embodiment 3: When the embodiment 2 is in use, the debris is made to slide down along the side by the V-shaped upper scraper 410. During the use, the friction between the accumulated debris and the upper scraper 410 and the steel plate is relatively large. In the process of sliding down along the side of the V-shaped upper scraper 410, the efficiency is relatively poor. Based on this, the solution of the embodiment 2 is improved, as shown in Figures 8 to 11:

The cleaning assembly 400 further includes an impact rod 430, an adjustment frame 440, a lower electromagnet 450, a traction film 460 and an upper electromagnet 480;

The impact rod 430 is cylindrical. In the initial state, the axis of the impact rod 430 is perpendicular to the ground, and the impact rod 430 is located in the V-shaped opening of the upper scraper 410;

There are two traction films 460, and the traction films 460 are V-shaped. The two traction films 460 are symmetrically arranged in the V-shaped opening of the upper scraper 410, and the side of the traction film 460 away from the V-shaped opening is fixed to the inner wall of the V-shaped opening of the upper scraper 410;

The impact rod 430 is located between the two traction films 460 , and the upper and lower ends of the impact rod 430 are respectively fixed on the two traction films 460 ;

The impact rod 430 is made of magnetic material;

The adjustment frame 440 is U-shaped, and one end of the U-shaped opening of the adjustment frame 440 is fixed to the inner wall of the V-shaped opening of the upper scraper 410;

The bottom inner side of the opening of the adjustment frame 440 is provided with a lower electromagnet 450 and an upper electromagnet 480;

The upper electromagnet 480 is located above the lower electromagnet 450. There are multiple lower electromagnets 450 and multiple upper electromagnets 480, respectively, and they are evenly spaced.

The height of the lower side of the upper electromagnet 480 is higher than the height of the upper side of the striking rod 430;

The traction film 460 is made of rubber.

When the upper scraper 410 is used to clean the side of the steel plate, the lower electromagnet 450 can be energized to absorb the magnetic material of the impact rod 430, so that the position of the impact rod 430 changes, and the impact rod 430 pulls the traction film 460 to deform. In the process of deformation, kinetic energy is stored. When the lower electromagnet 450 is powered off, the impact rod 430 is pulled by the traction film 460, rebounds and hits the upper scraper 410, and disperses the debris accumulated in front of the upper scraper 410; at the same time, the upper electromagnet 480 is energized to absorb the magnetic material of the impact rod 430. The position of the impact rod 430 is changed, and the impact rod 430 pulls the traction film 460 to deform, and the traction film 460 forms a moving angle with the steel plate. When the lower electromagnet 450 is powered off, the impact rod 430 is pulled by the traction film 460, rebounds and hits the steel plate, causing the steel plate to vibrate. During the vibration, the debris attached to its surface will be vibrated up; during normal operation, the upper electromagnet 480 and the lower electromagnet 450 at different positions can be controlled to be energized to adsorb the impact rod 430, so that the impact rod 430 hits different positions of the upper scraper 410 and the steel plate.

During the process of cleaning the debris on the steel plate by the upper scraper 410, the upper electromagnet 480 and the lower electromagnet 450 at different positions are controlled to be energized to adsorb the impact rod 430, so that the impact rod 430 impacts the upper scraper 410 and the steel plate at different positions. During the impact, the upper scraper 410 and the steel plate will vibrate. The vibration of the upper scraper 410 will disperse the debris accumulated in front. At the same time, when the steel plate vibrates, the debris attached to its surface will be vibrated up, and the debris will be more dispersed and will not accumulate in one place.

Embodiment 4: During the use of Embodiment 3, the impact rod 430 is adsorbed by energizing the lower electromagnet 450. When the power is off, the impact rod 430 impacts the upper scraper 410. During the impact, the entire upper scraper 410 is impacted, but the debris accumulated in front of the upper scraper 410 is gathered at the part where the upper scraper 410 contacts the steel plate, and the impact vibration dispersion effect is poor. Based on this, the solution of Embodiment 3 is improved, as shown in Figures 12 to 18:

The cleaning assembly 400 further includes a cleaning group, a sealing film 470 and a separation film 490;

The cleaning group includes a cleaning pipe 1 411 and a cleaning pipe 2 412. The side of the upper scraper 410 away from the V-shaped opening is provided with a cleaning pipe 1 411 and a cleaning pipe 2 412. There are multiple cleaning pipes 1 411 and cleaning pipes 2 412 respectively, and they are evenly spaced.

The gas outlet direction of the cleaning pipe 1 411 is perpendicular to the length direction of the guide plate 2 140 , and the gas outlet direction of the cleaning pipe 2 412 is perpendicular to the length direction of the cleaning pipe 1 411 ;

The sealing film 470 is V-shaped, and the sealing film 470 is fixed between the two traction films 460 . The two ends of the V-shaped opening of the sealing film 470 are fixed to the inner wall of the V-shaped opening of the upper scraper 410 . The sealing film 470 is fixed to the impact rod 430 .

An air storage space is formed between the sealing film 470, the traction film 460 and the upper scraper 410;

The partition membrane 490 is V-shaped and is located in the gas storage space. The side of the partition membrane 490 away from its V-shaped opening is fixed to the inner wall of the V-shaped opening of the upper scraper 410. The inner wall of the V-shaped opening of the partition membrane 490 is fixed on the sealing membrane 470. The partition membrane 490 divides the gas storage space into two upper and lower cavities that are not connected to each other.

The ends of the cleaning pipe 1 411 and the cleaning pipe 2 412 away from their openings are connected to the cavity below the separation membrane 490;

It also includes an air pump 700, which is fixed to the upper side of the upper scraper 410, and the output end of the air pump 700 is connected to the cavity above the separation membrane 490;

The impact rod 430 is provided with a one-way valve, and the one-way valve is connected to the cavity below the separation membrane 490. The one-way valve on the impact rod 430 allows external gas to enter the cavity below the separation membrane 490;

Both the cleaning pipe 1 411 and the cleaning pipe 2 412 are provided with a one-way valve, and the one-way valves in the cleaning pipe 1 411 and the cleaning pipe 2 412 only allow gas to be discharged;

The expansion coefficient of the separation film 490 is smaller than the expansion coefficient of the traction film 460;

The lower end of the impact rod 430 is fixed with a magnetic material.

During use, the air pump 700 can be used to inflate the cavity above the partition membrane 490 to tilt the impact rod 430. As the amount of air inflated by the air pump 700 is different, the impact rod 430 can form different angles. The upper electromagnet 480 or the lower electromagnet 450 adsorbs the magnetic material at the lower end of the impact rod 430. During the adsorption process, the impact rod 430 squeezes the cavity above the partition membrane 490. When the set degree is reached, the upper electromagnet 480 or the lower electromagnet 450 is powered off, and the impact rod 430 is reset. During the resetting process, it will swing repeatedly due to its own inertia, and impact the bottom of the upper scraper 410 multiple times. At the same time, during the repeated impacts, multiple jets can be sprayed through the cleaning pipe 1 411 and the cleaning pipe 2 412 to clean the debris accumulated in front of the upper scraper 410.

The air pump 700 can be used to inflate the cavity above the separation membrane 490 to tilt the impact rod 430. The amount of air inflated by the air pump 700 can control the degree of inclination of the impact rod 430. After the tilted impact rod 430 is adsorbed and powered off by the upper electromagnet 480 or the lower electromagnet 450, the impact rod 430 will collide with the bottom of the upper scraper 410 multiple times due to the elasticity of the connection, thereby improving the dispersion effect. At the same time, during the repeated swinging process, multiple jets can be sprayed through the cleaning pipe 1 411 and the cleaning pipe 2 412 to dredge and clean the debris accumulated in front of the upper scraper 410, thereby improving the cleaning effect.
