Description
Technical Field
The utility model belongs to a bicycle part forging tool, and particularly relates to a cutting die.
Background
At present, most of forging and cutting dies used for parts on bicycles are in an upper punch and lower discharge structure mode. However, the cutting effect of the lower punching die is common, the punching stroke is insufficient, so that punching is not in place, the precision of a positioning mode cannot be ensured, and the product quality is directly influenced.
As shown in fig. 1, the upper die plate 1 is provided with a peripheral baffle for installing the upper die core 3, the lower die base 2 is provided with the lower die core 4, the maximum stroke of the structure is the distance between the peripheral baffle of the upper die plate 1 and the lower die core, the stroke is smaller, the structures of the upper die core 3 and the lower die core 4 correspond to the larger length and diameter of the guide post, the requirement on the accuracy of the guide post is higher, and the cost of the die is higher.
Disclosure of Invention
In order to solve the problems, the utility model provides a cutting die which is convenient to install and use, has enough stamping stroke and ensures the product quality, and adopts the following technical scheme:
The cutting die comprises an upper die plate and a lower die holder, a plurality of guide posts are arranged between the upper die plate and the lower die holder, an upper die core is arranged at the lower part of the upper die plate, a die shank is arranged at the upper part of the upper die plate, the lower end of the die shank is connected with the upper die core, and the upper end of the die shank is used for being connected with a main shaft of a punch press;
The height of the lower die holder is 1.0-1.5 times of the height of the upper die core, the lower die holder is provided with a die cavity and a blanking cavity corresponding to the upper die core, the die cavity and the blanking cavity are arranged up and down and are communicated, and the blanking cavity is communicated with a discharge hole on a punch workbench.
Above-mentioned cutting die, the cope match-plate pattern top is equipped with the backing plate, the die shank is adorned on the backing plate admittedly.
Above-mentioned cutting die, the periphery of unloading chamber is equipped with the recess.
Above-mentioned cutting die, the die holder lower terminal surface is equipped with the slider in order to with punch press workstation sliding connection, the punch press workstation corresponds to be equipped with the spout.
The beneficial effects of the utility model are as follows: the height of the lower die holder of the die is increased, and only the upper die core is arranged, so that the length of the guide post is reduced, and the lower die holder is correspondingly provided with the die cavity, so that the stamping stroke is increased, and the cutting precision and stability are ensured. The arrangement of the die handle improves the connection reliability of the upper die core and the punch. The lower die holder is in sliding fit with the punch workbench, so that the installation is convenient, and the positioning accuracy of the die on the punch is guaranteed by improving the matching accuracy between the lower die holder and the punch workbench.

Detailed Description
The technical contents of the present utility model will be described in detail with reference to the accompanying drawings.
The embodiment is a cutting die, which comprises an upper die plate 1 and a lower die holder 2, wherein four guide posts 5 are arranged between the upper die plate 1 and the lower die holder 2. The height of the lower die holder 2 is 1.0-1.5 times of the height of the upper die core 3, namely the height of the lower die holder 2 is obviously increased. The die holder 2 is provided with a die cavity 11 and a blanking cavity 10 corresponding to the upper die core 3, the die cavity 11 and the blanking cavity 10 are arranged up and down and are communicated, and the blanking cavity 10 is communicated with a discharge hole on a punch press workbench 10. In this way, the length of the guide post 5 is reduced (similar to the height of the upper mold core 3), and the processing cost of the mold can be reduced.
The lower part of the upper template 1 is provided with an upper mold core 3, the top of the upper template 1 is provided with a base plate 6, a mold shank 7 is fixedly arranged on the base plate 6, the lower end of the mold shank 7 is connected and fixed with the upper mold core 3, and the upper end of the mold shank 7 is used for being connected with a main shaft of a punching machine. In order to improve the precision and the connection strength, the upper mold plate 1 is correspondingly provided with a concave cavity for assembling the upper mold core 3.
The lower end face of the lower die holder 2 is provided with a sliding block to be in sliding connection with the punch workbench 10, the punch workbench 10 is correspondingly provided with a sliding groove, the lower die holder and the punch workbench are directly assembled in a sliding mode during use, the required positions are fixed, positioning and mounting are very convenient, and positioning accuracy can be guaranteed through the accuracy of the sliding groove and the sliding block.
For convenient installation, a groove 9 is arranged on the periphery of the blanking cavity 10, and the blanking cavity can be used for holding during installation.
