Description
Technical field
The present invention relates to steel processing technique fields, and in particular to a kind of trailer special-purpose steel cross cutting off line.
Background technique
Channel steel is the strip steel that section is groove type, and it is compound section that category construction, which is used, and mechanical structural carbon steel
Fashioned iron steel, section configuration include work shape, T shape, H-shaped, C-shaped, V-arrangement etc..Since channel steel has good mechanical property and makes
With performance, thus its building structure, engineering structure, curtain wall engineering, mechanical equipment and in terms of obtained extensively
Application.
Carrying out processing cutting to fashioned iron makes it meet the requirement to various specifications structural member such as building structure, is fashioned iron processing
The key of manufacture.Currently, the cutting machine equipment of channel steel mainly includes the types such as abrasive wheel cutting machine, flame cutting machine and sawing machine.
Channel steel is cut using abrasive wheel cutting machine, flame cutting machine, due to micronic dust, the flue gas etc. generated in cutting, environment will cause
Pollution；Channel steel is cut using sawing machine, more scarfing waste material can be generated in saw blade cutting, wasted raw material；Saw blade needs
Frequently replacement, improves production cost.
In order to overcome the above problem, there is the dedicated cutting machine cut specifically for various types of channel steels.Such as
Application No. is 201420578144.0 patent applications, disclose a kind of fashioned iron hydraulic cutting-off machine, including hydraulic system, respectively with
Hydraulic system connected cutting system and electrical control cabinet；Hydraulic system includes motor, fuel tank and is arranged in hydraulic on fuel tank
Part, motor are connected with fuel tank, and are connected by high-pressure oil pipe with hydraulic part；Cutting system include cutting frame and with hydraulic part phase
Hydraulic cylinder even；Cutting off frame includes mold frame and mold；Hydraulic cylinder is connected by bindiny mechanism with cutting frame.The cutting
Machine structure is simple, and rationally, scarfing waste material is few, reduces the waste degree of resource for design；And precision is high, the smooth light of section
It is sliding.Channel steel is inserted into mold, is pushed using hydraulic control mold frame and cuts off channel steel.In the cutting machine cutting off processing,
The generation of the pollutants such as micronic dust, flue gas is not had.
Application No. is 201120282052.4 patent applications, disclose a kind of knife edge die of channel steel, include pedestal, bottom
Support is had on seat, lower die is fixedly installed on the side wall of the support, and the outer end face of lower die is equipped with the groove of flute profile, lower die
Top be equipped with upper mold, be connected with hydraulic cylinder above upper mold.The knife edge die cuts off principle are as follows: channel steel is inserted into groove
It is interior, it is pushed using upper mold and cuts off channel steel, reasonable in design, section is flat and smooth, and scarfing waste material is few, reduces resource
Waste degree；And what is utilized is that channel steel is cut off in upper mold pushing, is far smaller than saw blade to cutting force request, there is no need to frequent
Replace upper mold or lower die, relative reduction production cost.
Above two cut-off equipment, although overcoming lacking for abrasive wheel cutting machine, flame cutting machine and sawing machine cutting equipment
It falls into, but both without matched feeding mechanism and discharging mechanism, the fashioned iron after leading to cutting is deposited under knife edge die or mold
Side, influences cutting efficiency.And without the matched limit of design, undertaking or support device, it is well known that preparatory processing obtained
Fashioned iron is the profile with 2 meters or more length, if leading to die cutting process in the device of feed end and discharge end without support fashioned iron
Shaped Steel is difficult to generate the stress mutually assisted with pressing mold power in cutting-off process, fashioned iron cut-out point is caused to be adhered not without impetus
Easily take off；If the limiting device of no apical grafting fashioned iron discharging end face, not only influences the dimensional accuracy of the fashioned iron cut every time, but also
It is arbitrarily scattered accumulation after fashioned iron cutting, and incision can be deviated because of fashioned iron, and burr occurs, influence the integrated quality of punching block.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of trailer special-purpose steel cross cutting off line, with

The surface of steel, support stake 18 is provided with anticollision layer 19.
Trailer special-purpose steel of the invention is die cut off line, and the rupturing operation process and principle of punching block are specific as follows:
Distribution box 7 provides electric power for the control system of switching mechanism 84, the hydraulic control system of upper mold 5 and cylinder 81.According to
The size of the punching block of required processing sets the length in 82 stretches out cylinder 81 of telescopic rod of cylinder 81, guarantees 82 end of telescopic rod
The position-arresting disk 83 in portion can just resist the punching block in cutting-off process, to realize automation quickly positioning, guarantee punching block ruler
Very little precision.
Channel steel is inserted into lower mold 6, the whole power supply of cutting machine, hydraulic control system and the quilt of switching mechanism 84 are opened
Starting.At this point, upper mold 5 is located at home position, contact chip 842 and upper contact head 844 in an ON state, so that cylinder 81 be connected
Circuit, control telescopic rod 82 are stretched out out of cylinder 81, and position-arresting disk 83 is made to be moved to preset position；Meanwhile upper mold 5 pushes,
Position-arresting disk 83 apical grafting and limits punching block in lower mold 6 always, plays the role of quickly positioning, and guarantees that the punching block length of cutting begins
It is consistent eventually；Contact chip 842 follows upper mold 5 to push close to one end of upper mold 5, (this when upper mold 5 presses to minimum point
When for pressing mold cut off), contact chip 842 press to lowermost end and with lower contact 845 connect, thus disconnect cylinder 81 control electricity
Road, telescopic rod 82 are retracted in cylinder 81, at this time the no longer apical grafting punching block of position-arresting disk 83, and punching block is deviate from out of lower mold 6.
In punching block after the charging of 3 side of loading bay, the remainder of channel steel is stayed on loading bay 3, and is supported stake 18
Support.After cutting, the channel steel in support stake 18 is pushed, tilts channel steel relative to lower mold 6, to make the punching block of discharge outlet
Broken by lower mold 6 card and is detached from lower mold 6.In cutting-off process, tray 94 supports the bottom end of punching block, the moment of cutting, pressure
Spring 93 is that tray 94 provides a upward screen resilience, cooperates the limitation of lower mold 6 and position-arresting disk 83, makes punching block from blanking plate
Blanking is slid on 10 to specified punching block collecting zone.Since punching block is the inclined cutting in lower mold 6,
Center of gravity on tray 94 it is amesiality, and the side of punching block centre-of gravity shift is arranged in blanking plate 10, to guarantee to cut
The punching block having no progeny smoothly enters blanking plate 10.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
