Die with inner punching cam driver mechanism

Abstract

The invention provides a die with an inner punching cam driver mechanism. The die with the inner punching cam driver mechanism comprises an upper die seat, a lower die seat, the cam driver mechanism, a driving block, and an edging embedding block which is arranged on the upper die seat, wherein the cam driver mechanism comprises a sliding block, a punch and a returning mechanism; the sliding block is arranged across the edging embedding block and then is mounted into the upper die seat by sliding; the punch is arranged at the front end of the sliding block; the returning mechanism is arranged between the sliding block and the upper die seat; the driving block is mounted on the lower die seat and is provided with an inclination driving surface for driving the sliding block. According to the die with the inner punching cam driver mechanism, the punching accuracy can be ensured through uniform and high-accuracy guide column guide mechanisms of an upper die and a lower die, so that the cam driver mechanism is prevented from shaking due to the gap error of a traditional secondary guide mechanism; in addition, the problem that a punched hole in a product is changed as a secondary guide part is worn can be avoided, so that the accuracy of the punched hole in the product can be effectively ensured, and the problem that the increase of die leads to consumption of a large number of labors and materials can be solved.

Description

Technical field [0001] The invention relates to the technical field of molds, in particular to a mold with an inner punching oblique wedge mechanism. Background technique [0002] Among auto parts, especially some large and important covering parts (such as: rear apron outer panel, tailgate outer panel, etc.), because it not only meets the appearance requirements of the car, but also meets the rigid requirements of installing other parts in the middle of the part. Basically, the middle part of the part will have the feature of mounting holes on the steep wall, which will make the punching on the inner steep wall very difficult. The traditional method is generally achieved by using a built-in inclined wedge or adding a punching die. [0003] If the built-in oblique wedge mechanism installed in the press is used for punching, firstly in the mold design stage, it is necessary to strictly grasp the precision and reliability of the guidance of the press. You cannot simply use the tradit...

AI Technical Summary

Problems solved by technology

The presser itself has to move up and down during the stamping process, and the guide accuracy of the presser has a great influence on the punching. If the guide gap is too large during processing and the presser plate moves randomly when it moves, the punching accuracy of the part cannot be guaranteed. , and this kind of mechanism is extremely difficult to manufacture. When grinding and combining the punch and die, due to the narrow operating space of the internal structure of the presser and the limited viewing angle, it is difficult to grind and combine the punch in place, and the machining cost is relatively high. high

[0004] The above situation can be realized under the condition that the internal space of the part is relatively spacious, but if the part is extremely narrow and the internal space is not enough to design the built-in wedge, then only a special mold can be added for punching, which requires additional manpower, Equipment to design and manufacture new molds will consume a lot of manufacturing costs

In addition, for the production department, the size of such stamping parts is too large, and the quality requirements are very high, and the molds in each process are more precise and complex. In this way, on the basis of the large stamping molds that originally required many processes to complete, additional A set of molds to achieve, the consequences not only increase the burden on stamping equipment, but also increase the cost of labor and other aspects

In the current situation of rising manufacturing costs, for enterprises, it will undoubtedly increase the pressure on enterprises.
