Description
Technical field
The utility model relates to steel processing technique fields, and in particular to a kind of quick positioning-cutting device of punching block.
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, and section is flat and smooth for design.Channel steel is inserted into
Into mold, is pushed using hydraulic control mold frame and cut off channel steel.In the cutting machine cutting off processing, micronic dust, cigarette are not had
The generation of the pollutants such as gas.
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 charging and discharging mechanism, the fashioned iron after leading to cutting is deposited in below knife edge die or mold, is influenced
Cutting efficiency.And without designing matched limit, accept or support device, it is well known that the fashioned iron that preparatory processing obtains is
Profile with 2 meters or more length, if leading to die cutting process Shaped Steel in the device of feed end and discharge end without support fashioned iron
It without impetus, is difficult to generate the stress mutually assisted with pressing mold power in cutting-off process, causes fashioned iron cut-out point to be adhered and be not easy to take off；
If the limiting device of no apical grafting fashioned iron discharging end face, influences the positioning accuracy of fashioned iron cut every time, by artificially feeding positioning
The length of punching block, different people's operations have differences, cause the dimensional discrepancy of finished product punching block big, influence the integrated quality of punching block.
And it artificially positions, control location efficiency is low, causes processing efficiency low.
