Arc-shaped stamping die for metal plate

Abstract

The invention discloses an arc-shaped stamping die for a metal plate. The arc-shaped stamping die comprises a base, wherein a plurality of hydraulic rods are symmetrically mounted at the upper end ofthe base; a stamping seat is mounted at the upper ends of the plurality of hydraulic rods; a plurality of buffer grooves are symmetrically formed in the lower end surface of the stamping seat; a mounting seat is fixedly mounted on the lower end surface of the stamping seat; a plurality of limiting columns are symmetrically mounted on the lower end surface of the mounting seat; an upper die seat isarranged on the plurality of limiting columns in a sleeving manner; a plurality of buffer rods are symmetrically mounted on the upper die seat; the upper end of each buffer rod extends into the corresponding buffer groove and is fixedly provided with a buffer block; and a plurality of buffer springs are symmetrically mounted between the mounting seat and the upper die seat. The arc-shaped stamping die is ingenious in structure and reasonable in design; a buffer mechanism is designed to reduce the die pressing speed and increase the success rate of die pressing; and meanwhile, a detachable mechanism is designed to replace arc-shaped female dies of different models, so that the device is higher in applicability and the adaptive range of the device is increased.

Description

technical field [0001] The invention relates to the technical field of stamping equipment, in particular to a sheet metal stamping arc mold. Background technique [0002] Stamping die is a special process equipment for processing materials into parts in cold stamping processing. Or plastic deformation, so as to obtain a pressure processing method for the required parts. The important parts of the stamping die include the punch and the die. When stamping the U-shaped groove on the thin sheet metal, first place the thin sheet metal on the positioning plate. The punch is used to stamp the sheet metal, and the U-shaped groove is formed by the die. [0003] There are also some sheet metal stamping arc dies in the prior art. For example, a Chinese patent with application number 201910211525.2 discloses a stamping die for arc sheet metal workpieces, including a transfer device, an upper die set and a lower die set, and a transfer device A transmission wheel is provided on the fro...

Problems solved by technology

[0004] Although the above-mentioned device can achieve the purpose of automatic demoulding, it does not buffer the impact force, and directly uses a strong impact force to stamp the sheet metal part. In the case of a large impact force, the sheet metal part will be deformed excessively, resulting in stamping failure. , leading to an increase in the scrap rate
