Description

Stub bar, material tail cutting device that mould was used

Technical Field

The utility model relates to a blank device for the mould, specific stub bar, the material tail cutting device that manual switch's mould was used that says so.

Background

For the material rolling die, the stub bar and the material tail of the material belt are often uneven and cannot be processed, so that the existing stub bar and the material tail are cut off by a front cutter manually, but the cutting difficulty of the scissors is high for the thicker material belt, and the cut surface after cutting is uneven, so that waste materials are easily left in the die, and the die is easily damaged.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art and exist not enoughly, provide a stub bar, material tail cutting device that mould that makes it carry out the switching under shearing and not shearing state through workman operation control was used.

In order to achieve the above object, the utility model adopts the following technical scheme: a stub bar, material tail cutting device for mould, including upper die base, upper bolster, activity cardboard, position the cardboard, splint seat, take off the flitch, cut off the drift, lower die edge of a knife go into son, lower die base, the upper die base is opposite to lower die base; the upper backing plate is arranged on the bottom surface of the upper die holder; the bottom surface of the upper backing plate is provided with a guide rail group; the clamping plate seat is arranged on the bottom surface of the upper padding plate and is connected and matched with the upper padding plate; the splint seat is internally provided with an installation groove which is matched with the upper padding plate to form an installation bin; the movable clamping plate is positioned in the mounting bin; the movable clamping plate is arranged on the bottom surface of the upper base plate and is connected and matched with the guide rail group, so that the movable clamping plate can horizontally slide along the guide rail group in the mounting bin; a handle is arranged on one side of the movable clamping plate, and the movable clamping plate can slide along the guide rail group by operating the handle; a plurality of upper inclined plane grooves are arranged on the bottom surface of the movable clamping plate; the positioning clamping plate is positioned in the mounting bin; the positioning clamping plate is connected and matched with the bottom surface of the mounting groove in the clamping plate seat through a plurality of springs and positioning columns, so that the positioning clamping plate is in alignment fit with the movable clamping plate; the upper surface of the positioning clamping plate is provided with lower inclined plane grooves corresponding to the upper inclined plane grooves in number, position, size and shape; the stripper plate is positioned below the clamping plate seat and is connected and matched with the positioning clamping plate through a plurality of spring parts penetrating through the clamping plate seat; the cutting punch penetrates through the stripper plate and the clamping plate seat and then is connected and matched with the positioning clamping plate; the lower die knife edge insert is arranged on the lower die base; and a cutting groove which is in contraposition fit with the cutting punch is formed in the lower die knife edge insert.

The utility model discloses during the implementation, through handle pulling movable clamp plate, the last inclined plane groove that makes movable clamp plate is relative with the lower inclined plane groove of location cardboard, and at this moment, location clamp plate receives spring action upward movement, makes and cuts off the drift and goes upward, and when making cope match-plate pattern, lower bolster along with last mould, the lower mould synchronous motion of mould, it does not process the disconnected area to cut off the drift. Similarly, when the stub bar and the stub bar need to be cut, the movable clamping plate is pushed by the manual holding handle, the upper inclined plane groove and the upper inclined plane groove are in staggered fit, the positioning clamping plate is further pushed to compress the spring to move downwards, the cutting punch is exposed out of the stripper plate, and finally the cutting work of the stub bar and the stub bar is finished.

The utility model discloses simple structure, low in manufacturing cost, reasonable in design can carry out organic cooperation with current mould, replace the artifical material of cutting of tradition.
