Description

Automobile hardware chamfering continuous mold

technical field

The invention relates to the technical field of automobile hardware processing, in particular to a chamfering continuous mold for automobile hardware.

Background technique

Hardware refers to tools obtained by processing and casting gold, silver, copper, iron, tin and other metals, which are used to fix things, process things, decorate, etc., and hardware is more widely used in the automotive field. In the process of processing, chamfering is required. The purpose of chamfering is to remove the burrs caused by machining on the parts, and also to facilitate the assembly of parts. Generally, chamfering is made at the end of the parts. In order to improve production efficiency, the current hardware is chamfered. The corners are all made of special molds. The chamfering method of this mold is formed by direct stamping of the hardware. Stamping is to apply external force to the hardware by the press and the mold to cause plastic deformation or separation, so as to obtain the required The forming and processing method of workpieces of different shapes and sizes, stamping dies are a commonly used process equipment for existing metal or non-metal processing parts or semi-finished products.

However, today’s automotive hardware chamfering continuous molds need to bend the two ends of the hardware twice when chamfering square hardware, so that the chamfering of the hardware has a square structure. This processing method , not only increases the processing flow, increases the trouble of operation, and reduces the work efficiency, but also the deviation of the bending angle from 90° is too large, which is not convenient for matching and using on the car, the product performance is reduced, and it is not convenient for automatically chamfering the hardware of the good angle The parts are automatically demolded, which further reduces the processing efficiency.

In order to solve the above problems. For this reason, a continuous mold for chamfering of automobile hardware parts is proposed.

Contents of the invention

The object of the present invention is to provide a continuous mold for the chamfering of automobile hardware, place the piece to be chamfered on the upper end of the support box, start the hydraulic cylinder, drive the chamfering assembly to move down, and then drive the upper die to move down, at this time Press the die to wait for the chamfering part to be chamfered.
