Description

Shotgun shell plug pad filling machine

technology field or

The invention belongs to the technical field of shotgun shell manufacture, and in particular relates to a machine for filling and closing the plug of a shotgun shell case.

Background technique

Shotgun bullet refers to the bullet used on the smoothbore shotgun. It is a kind of shotgun. It is one of the most commonly used civilian bullets in the world. It is mainly used for hunting, shooting competitions and explosion protection. At present, my country mainly produces shotgun bullets of two calibers, No. 12 and No. 16. The bore diameter of the No. 12 shotgun bullet is 18.40-18.70mm, and the bore diameter of the No. 16 shotgun bullet is 16.80-17.10mm. Shotgun shells consist of shell casings, primers, gunpowder, magazine holders and projectiles.

Shotgun shells are usually made of plastic. In the production process of shotgun shells, one end of the plastic shell is closed and then filled with plugs. The traditional processing method is to mechanically close the shells with a closing machine, and then manually fill the plugs. The operation method of manual plug filling is as follows: the worker sits in front of the operating table, holds the closed end of the plastic shell with one hand and faces down, and holds a plug with the other hand, and then scrapes the inner hole wall of the shell with a plug right-angle knife to make it Expand it for easy filling, and then use your thumb to press the concave side of the plug into the inner hole of the tube until it is flattened to complete a filling. This processing method is labor-intensive and prone to plug pad positioning deviation (concave surface loading reverse); and, on average, each person can fill about 3,000 pieces per shift (eight hours of work), and the production efficiency is low.

Contents of the invention

The invention provides an integrated machine for filling and closing the plug pads of shotgun shells. Five stations of feeding, expanding the mouth, filling the plug pads, closing the plugs and unloading materials work simultaneously, and the production efficiency is five times that of the traditional method.

The invention provides a special equipment integrating machinery, electricity and pneumatics, and the technical proposal is:

The all-in-one machine is composed of AC motor, reducer, transmission parts, and processing device. The five stations of the six-station turntable work at the same time in each beat, which are feeding, expanding, filling plugs, closing and returning materials.

The feeding station is connected with the feeding chute.

The expansion station is that the cylinder drives the plug feeding punch to slide back and forth in the guide sleeve to push the cartridge case to the position of the positioning baffle.

The filling station is that when the intermittent six-station turntable rotates, the end face bumps push the cartridge case forward and stick to the plug pad feeding mold; The direction vibrates upward along the track; when the plug feeding punch returns, the plug automatically falls in the feeding mold for the next filling.

The closing station is that the closing of the cartridge case is clamped by an adjustable spring sheet, and the punching closing die slides in the guide sleeve of the closing die.

The material stripping station is that the stripping bumps on both sides block the cartridge case when the six-station turntable is turned, and fall into the unloading chute to slide down.

The invention realizes the automatic loading of the hunting plug pad and the automatic closure of the plastic cartridge case, and has reliable practical performance in the production process, and high precision after the workpiece is formed. Compared with the traditional processing method in the same industry, it improves the production efficiency and saves human and material resources.

Detailed ways

Example 1

As shown in Figure 1, the all-in-one machine of this embodiment is composed of an AC motor, large and small pulleys, a worm reducer, a hexagonal indexing plate, a transmission box, and a six-station turntable. The work includes feeding, flaring, filling plugs, closing and returning materials.

The feeding station is connected with the feeding chute.

The described flaring station is that the cylinder drives the plug feeding pad punch 8 to slide back and forth in the guide sleeve, and pushes the cartridge case 5 to the position of the positioning baffle plate 9 .

The described filling station is that when the intermittent six-station turntable 1 rotates, the end face bump 3 (direction A) pushes the cartridge case 5 forward to be close to the pad feeding mold 10; the pad 6 moves along the magnetic vibrating hopper 11 (generally components, adjustable in frequency), and move upward along the track in a counterclockwise direction in a vibrating manner; since the plug pad 6 is loaded into the plastic tube shell in a direction, it is necessary to control the direction in which the plug pad 6 enters the plug pad delivery slideway 12 . Three arc surfaces slightly smaller than the concave surface of the plug pad are installed on the track before the plug pad 6 enters the slideway. The size of the arc panel is adjustable, and the concave surface of the plug pad can be used to control the front and back sides. When encountering a circular arc surface, it will automatically fall off the track due to vibration; the bottom surface of the plug pad 6 with the concave surface upward is flat, and will not tilt during the vibration process, and can enter the plug pad delivery slideway 12 smoothly through the track. Slideway 12 will automatically return when it is full.

When the plug pad punch 8 was returned, the plug pad 6 would automatically fall down in the feeding mold 10 for filling next time.

The closing station is that the shell closing is clamped by the adjustable spring leaf 2, and the stamping closing die 4 slides in the closing die guide sleeve 13.

The described material removal station is that the material removal protrusions 14 on both sides block the cartridge case 5 when the six-station turntable 1 is turned, and fall into the feeding chute 15 and slide down.

The six-station turntable has the functions of mold, material feeding and processing in one, which reduces the intermediate links, can effectively improve the operation and processing accuracy, and ensure the reliable operation of the machine tool. The outer diameter of the turntable is 220mm, the thickness is 62mm, and the aperture is 24mm.

The plastic shell enters the slot of the six-station turntable from the slideway. When the turntable is turned to the position, the three stations of flaring, filling and closing are clamped at the same time. The clamping of each station can be adjusted according to the processing. The adjustable spring piece The degree of tightness (for example, the flaring station can be adjusted looser, the filling plug pad can be adjusted slightly tighter, and the closing should be adjusted appropriately according to the closing quality requirements). The spring leaf is made of high-quality steel belt, the thickness is 1mm, the width is 20mm, and the length is determined according to the needs.

Because the weight of the plastic shell is too light, if the gap between the baffles on both sides of the slide is too small, the shell will not slide in place, so the slide is widened to 4mm wider than the shell. But this brings problems to the filling plug, that is, the filling plug is often stuck. Using the slope of the end face bump, the end face bump is installed on the positioning plate, and the six-station turntable rotates to push the plastic shell to move forward 4mm, so that the plastic The cartridge case is closely attached to the plug pad feeding mold, so that there is no gap between the loaded cartridge case and the plug pad mold, so that 100% filling of the plug pad will not be stuck.

1. Feeding

See the feeding chute 7 of accompanying drawing 1, put plastic cartridge case 5 (seeing Fig. 6) on slideway 7 (slideway 7 can put into 25 plastic cartridge case 5), pass 15 degree angle slideway 7, cartridge case 5 Automatically enter the six-station turntable slot 1. There are baffle plates on both sides and the entrance of the slideway 7, which can prevent the cartridge case 5 from bouncing upwards when rolling.

2 flaring

See accompanying drawing 2, with 50mm diameter cylinder, stroke 20mm, thrust 11.78kg flaring. The cylinder drives the plug feeding punch 8 to slide back and forth in the guide sleeve, pushes the cartridge case 5 into place, that is, pushes it to the position of the positioning baffle 9, and uses the plug feeding punch 8 at an angle of 60 degrees to expand the plastic cartridge case 5 by 1.3 to 1.4 mm. Prepare for filling. If there is no this flaring process, the size of plug pad 6 (seeing Fig. 7) and the size of plastic cartridge case 5 can't be filled to zero, so increasing this process is convenient for filling.

3 loading

See accompanying drawing 3, when the six-station turntable 1 rotates, push the plastic cartridge case 5 forward 4mm to be close to the pad feeding mold 10 with the end face bump 3 (A direction). The plug pad 6 vibrates counterclockwise along the track along the magnetic vibrating hopper 11 (a common component with adjustable frequency). There is an orientation device in the middle of the track, and the concave surface of the plug pad is used to control the front and back sides. Three The arc surface is smaller than the concave surface of the plug pad, and the size of the arc panel is adjustable. During the debugging process, when the plug 6 with the concave surface facing downward is encountered, it will tilt and fall automatically through vibration; while the plug pad 6 with the concave surface upward, because the bottom surface is Plane, can not tilt in the vibration process, can pass smoothly and enter conveying chute 12, when chute 12 is full and will return automatically. When the plug pad punch 8 was returned, the plug pad 6 would automatically fall down in the feeding mold 10 for filling next time. The plug feeding punch 8 is driven by a cylinder with a diameter of 25mm, a stroke of 50mm, and a thrust of 27kg. The stroke of the cylinder is limited, and it returns automatically when it is in place, and the filling is completed.

4 closed

Closing with conventional methods cannot meet the quality requirements, and the existing problems are that the closing is not round, and the length is inconsistent and out of tolerance. The test found that a stamping type closing die 4 has reached the quality requirements, see accompanying drawing 4. Closing is clamped with adjustable spring leaf 2, and stamping type closing die 4 slides in closing die guide sleeve 13, and thrust is selected φ 100 cylinder, and thrust 47kg (air pressure 6kg), stroke is controlled at 20mm.

5 returns

See attached drawing 5, when returning the material, use the return protrusions 14 on both sides to snap off the plastic cartridge case 5 when the six-position turntable 1 is turned, and fall into the lower trough 15 to slide down. This method can ensure 100% return of the material .
