Description

A waste cutting structure at the end of a continuous die

technical field

The utility model relates to the field of stamping dies, in particular to a waste cutting structure at the tail of a continuous die, which is a good solution for the maintenance of waste cutting knives during mass production.

Background technique

At present, the automobile industry in my country and even the world is booming, and the market has higher and higher requirements for automobiles, whether it is function or appearance. Market demand has promoted the development of the automobile industry, and the manufacturing and design level of automobile molds has also been continuously improved. Due to the increase in labor costs in recent years, more and more stamping factories require the newly developed automotive molds to be produced using continuous molds. The continuous mold can realize continuous and rapid production, stable product quality, reduce the number of machines and save labor, etc. However, its maintenance difficulty and maintenance are relatively complicated. For example, when many products are produced in a stamping factory, due to long-term rapid punching, the punch and knife edge are worn and collapsed, requiring frequent maintenance or even new production by mold repair personnel, which delays delivery time and wastes manpower and material resources.

Contents of the invention

Aiming at the problem of frequent maintenance of continuous die cutting knives, we provide a simple and easy-to-change cutting punch and knife edge that can be used on multiple sides, which saves time for mold repair and maintenance. In order to achieve the above purpose, the utility model adopts The following technical solutions: the utility model includes an upper mold structure and a lower mold structure, and the upper mold structure includes: an upper mold fixing seat 1, an upper mold positioning pin 2, a cutting upper mold punch 3, and the cutting upper mold punch 3 fixed in the upper mold holder 1;

The lower die structure includes: cut-off lower die edge 4 , lower die positioning pin 5 , lower die holder 6 , and the cut-off lower die edge 4 is fixed in the lower die holder 6 .

Preferably, an upper die positioning pin 2 is connected between the cutting upper die punch 3 and the upper die fixing seat 1 .

Preferably, a lower die positioning pin 5 is connected between the lower die fixing seat 6 and the cutting edge 4 of the lower die.

Beneficial effects of the utility model: when the mold is assembled, the fixing pins are respectively installed into the fixing seats, and then the punches or knife edges are inserted to guide them and fixed with screws. The structure is simple, the occupied space is small, and the processing and maintenance Convenience; improve production efficiency.

detailed description

The utility model comprises a continuous mold tail cutting waste material structure, including an upper mold structure and a lower mold structure,

As can be seen from Figures 1 and 2, the upper die structure includes: upper die fixing seat 1, upper die positioning pin 2, cutting upper die punch 3, and the cutting upper die punch 3 is fixed on the upper die In the fixed seat 1 , an upper die positioning pin 2 is connected between the cutting upper die punch 3 and the upper die fixed seat 1 .

When the cutting edge of the upper die cutting punch 3 is worn or chipped, and the punch needs to be repaired, the general treatment method is to lower the edge of the knife edge or weld and repair the joint, but the temporary solution is not the root cause, and external conditions need to be used, but this structure , the above situation will not occur, just remove the punch and rotate it 90°, and install it again, so that it can be changed 7 times (upside down can also be used), in order to save time, improve production efficiency, and maintain more convenient.

As can be seen from Fig. 3 and Fig. 4, the structure of the lower die includes: cut-off lower die edge 4, lower die positioning pin 5, lower die holder 6, and the cut-off lower die edge 4 is fixed in the lower die holder 6 , the lower mold fixing seat 6 and the lower mold cutting edge 4 are connected with the lower mold positioning pin 5, the cutting edge of the lower mold cutting knife 4 wears or collapses, and when the knife edge needs to be repaired, the general processing method is to lower the knife edge surface or Welding and repairing, but the temporary solution is not the root cause, and external conditions need to be used, but with this structure, the above situation will not occur. Just remove the punch and rotate it 90°, and install it again. Repeatedly, it can be replaced. 3 times. In order to save time, improve production efficiency and make maintenance more convenient.

The above is a detailed description of an implementation example of this structure, but the content described is only a preferred implementation of this structure, and cannot be considered as a technical solution for limiting this structure. Those skilled in the industry should understand that this structure can be modified Or replacement, to achieve the same technical effect, as long as it can meet the needs of use, it should belong to the patent scope of this structure.
