Description

Die structure for reducing blanking force

Technical Field

The present utility model relates to a stamping die for stamping a plurality of punched holes at a time, and more particularly, to a stamping die for reducing a blanking force.

Background

The bottom plate component of the silk screen turnover box product is widely used in silk screen turnover box products requiring permeability, the bottom plate of the bottom plate component is required to be punched in the use process to meet the use requirement, and the processing of the bottom plate component is completed by using a gantry type punching machine and automatic feeding equipment for punching dies of two rows of punches. The two rows of punches of the original design stamping die are on the same plane, no height difference exists between the two rows of punches, and the blanking force of the stamping machine is insufficient due to the fact that the number of the punches is large at the same time, so that the product quality is affected. If a single-row punch is used for punching, the blanking force is too large.

Disclosure of Invention

In order to meet the principle of one-time punching and reduce blanking force, the utility model aims to provide a die structure capable of reducing blanking force.

The technical scheme of the utility model is as follows: the die structure for reducing blanking force comprises an upper die and a lower die, wherein the upper die comprises an upper die plate, an upper die fixing plate, a punch fixing plate and an upper pushing plate, guide sleeves are arranged at four corners of the upper die plate, two rows of punching pins and polyurethane rods are arranged between the punch fixing plate and the upper pushing plate, inner guide posts are arranged at four corners of the punch fixing plate, the lower die comprises a lower die plate, a lower die plate fixing plate and lower dies, guide posts corresponding to the guide sleeves are arranged at four corners of the lower die plate, one row of punching pins is long punching pins, the other row of punching pins is short punching pins, the height difference between the long punching pins and the short punching pins is larger than the plate thickness of a machined bottom plate, and the number of each row of punching pins of the long punching pins and the row of punching pins is larger than 10 and smaller than 20.

The die structure for reducing the blanking force can ensure two rows of holes to be punched at one time and can reduce the blanking force. The working efficiency is ensured, the requirement on the punching machine is reduced, and the product quality is ensured.
