Description

Stamping die for producing wheel hub balance block

Technical Field

The utility model relates to a punching press production field, more specifically relates to a stamping die of production wheel hub balancing piece.

Background

At present, automobile wheel balance weights at home and abroad have two modes of an externally-hung type and an internally-arranged pasted type. The externally-hung wheel balance block has the advantages of convenience in assembly and disassembly and the like, but the wheel hub is required to be provided with a circle of flange so as to be convenient for externally hanging the balance block, so that the appearance of the automobile wheel is influenced to a certain extent, and on the other hand, the risk of falling off is also caused, and the safety problem is easy to occur. In recent years, with the mass use of automobile aluminum alloy hubs and the harsh requirements on the appearance of automobiles, high-grade automobiles and even common household automobiles increasingly adopt built-in adhesive hub balance weights, ten balance weights with different weights are configured according to the standard of a car, and the market demand is very large.

To the production flow of pasting formula wheel hub balancing piece for purchasing the steel billet earlier among the prior art, forging the steel billet into the suitable steel sheet of thickness, put the steel sheet on the punch press blanking at last, form the balancing piece that the size is suitable one by one, this kind of production mode machining efficiency is lower, so slowly popularize into the raw materials now and choose the reinforcing bar for use, forging the back with suitable thickness of handling, punch again, produce through this kind of whole set of assembly line mode, production efficiency has obviously been improved, and avoid when the punching press add the steel sheet need be put repeatedly in traditional punching press man-hour, non-operating time has been reduced, so just need use dedicated punching press mould when adopting assembly line mode production, but current punching press mould is too simple either structure, the reliability is lower, or the structure is complicated, production and cost of maintenance are higher.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a stamping die of production wheel hub balancing piece.

In order to solve the technical problem of appeasing, the technical scheme of the utility model is that: the utility model provides a stamping die of production wheel hub balancing piece, includes mould and lower mould, be equipped with guider, blanking hole, spacing square hole and fixed column on the lower mould, guider includes left guide rail and the right guide rail that the symmetry set up, forms a square channel between left guide rail and the right guide rail, and the width height of this square channel suits with the width height of raw materials, go up the mould under the bottom surface corresponds blanking hole position department and is equipped with the drift that suits with the blanking hole, and it has the square column to go up the mould bottom surface and corresponds spacing square hole position department rigid coupling, and this square column cooperatees with spacing square hole, goes up mould bottom surface and corresponds fixed column position department and is equipped with circular through-hole, goes up the mould and adorns on the fixed column through.

Preferably: an elastic cushion pad is fixedly connected to the bottom surface of the limit square hole.

Preferably: the fixed column is sleeved with a compression spring.

Preferably: the top surface of the upper die is provided with a buffer layer.

The utility model has the advantages that: the utility model has the advantages of simple structure, high reliability and high production efficiency.
