Description

Noise-reducing and shock-proof stamping die

Technical Field

The invention relates to the technical field of stamping dies, in particular to a shockproof stamping die capable of reducing noise.

Background

The stamping die is essential technological equipment for stamping production, is a technology-intensive product, is widely used in production and manufacturing enterprises, and has great relation to the quality, the production efficiency, the production cost and the like of stamping parts. The height of the mold design and manufacturing technology level is one of the important marks for measuring the height of the national product manufacturing level, and determines the quality and the benefit of the product and the development capability of a new product to a great extent. The stamping die is a tool for stamping and forming made of metal and other rigid materials, and generally comprises an upper template, a male die, a lower template, a female die, a cushion plate and the like. In the course of the work, can take place the striking between each plate, can produce the noise after the striking, the noise that produces not only can influence staff's work efficiency, and to the human harm of staff, be unfavorable for the healthy permanent development of enterprise, especially high-speed stamping die, this kind of noise problem is especially serious, because high-speed stamping die is in high-speed stamping process, especially when stamping die's stamping speed reaches more than 1000 per minute, can produce very big vibration in the stripper motion process, stamping die's cope match-plate pattern and lower bolster carry out the punching press collision, make stamping die produce and rock, can lead to mould precision unstability on the one hand from this, on the other hand pulse pressure amplitude is big, the frequency is high, thereby very easily lead to fatigue, the vibration of mould can bring the deformation for the template, and then reduce mould precision and life-span.

Compared with the application number CN201721120662.8, the device sets up a plurality of section difference slots on the lower bolster in noise reduction and shockproof aspect and realizes the noise reduction, and the effect that can realize the noise reduction is limited, and the buffering shock attenuation effect that can reach only through the bolster in the aspect of the buffering is not obvious, so designed a noise reduction and shockproof stamping die to these problems.
