The use of composite bus bars provides a modern, easily designed, quickly installed and structurally sound power distribution system, as compared to conventional, bulky, time consuming and cumbersome wiring methods.

According to the development requirements of projects and the huge market requirements after consideration, the continuous molding manufacturing process is adopted in the stamping mode, so that the situation that materials are adopted for connection between products cannot be avoided, and the continuous and effective operation of production is guaranteed. The blanking burrs/edge sharp corners appear at the position where the products are connected after the products are finally cut off in the cutting process, manual treatment is needed, a large amount of manpower/material resources/financial resources are consumed, the effect is not obvious, the consistency of the products is poor, and the appearance reject ratio is high.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the internal chamfering device for the laminated busbar progressive die, which solves the problem that the quality of a copper bar product is unqualified, reduces the labor cost and improves the efficiency.

The purpose of the utility model is realized as follows: the inner chamfer device of the laminated busbar progressive die comprises a prepressing assembly and a punching assembly, wherein the punching assembly is positioned in the subsequent process of the prepressing assembly;

the prepressing assembly comprises an upper prepressing head and a lower prepressing head, a pair of upper prepressing punches are arranged on the bottom surface of the upper prepressing head, and a pair of lower prepressing punches are arranged on the top surface of the lower prepressing head;

the punching component comprises an upper male die and a lower female die, and a pair of wedge-shaped bosses are arranged at the top of the lower female die.

Compared with the prior art, the utility model has the beneficial effects that:

by using the utility model to produce and manufacture the laminated busbar in a prepressing mode, the punched product does not have burrs/edge sharp corners, the process of manual secondary processing is omitted, the cost is reduced, the efficiency is improved, the mechanical property and the chemical property of the material are not changed, the laminated busbar can be applied and produced in large batch, and the cost is low and the benefit is high.

As an improvement of the utility model, the side surface and the bottom surface of the upper male die are transited through an arc surface. The arc-shaped structure solves the problems that in the process of stamping, the stamping product is subjected to high-low temperature cyclic impact to generate stress release, so that the injection molding assembly is cracked, the whole vehicle assembly requirement cannot be met, the scrapping is caused, and even the hidden danger of recalling is caused after the whole vehicle is assembled.

As an improvement of the utility model, the top surface of the wedge-shaped boss is a horizontal plane, and the inner side surface of the wedge-shaped boss is a vertical plane. The planar structure has better strength.
