Problems solved by technology

In the traditional stamping die, the plate can only be deformed in the stamping direction, and the side of the plate needs to be processed separately. If the side punching is required, another set of molds needs to be selected for re-stamping, which greatly reduces the processing efficiency and improves the processing efficiency. cost

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 1~4 A stamping die shown includes a lower die 1 and an upper die 2 matched with the lower die. The lower mold 1 includes a lower mold substrate 11 and a lower mold table 12 fixed on the lower mold substrate 11 . The upper mold 2 includes an upper mold substrate 21 and an upper mold platform 22 fixed on the upper mold substrate 21 , and the upper mold platform 22 is matched with the lower mold platform 12 correspondingly. Two guide sleeves 201 are fixed on both sides of the lower end surface of the upper mold base plate 21 , and two guide columns 101 are fixed on both sides of the upper end surface of the lower mold base plate 11 . The guide sleeve 201 is sleeved on the guide post 101 and can move axially along the guide post 101 , and guides the stamping process of the upper die and the lower die through t...

Abstract

The invention relates to the field of punching dies, in particular to a punching die of a metal plate. The punching die comprises a lower die and an upper die matched with the lower die which comprises a lower die baseplate and a lower die platform fixed on the lower die baseplate, the upper die comprises an upper die baseplate and an upper die platform fixed on the upper die baseplate, and a horizontal punching die set is arranged on the lower die baseplate and comprises a punching base station, a lower wedge-shaped block arranged on the punching base station movably and a horizontal punching needle arranged at the end of the lower wedge-shaped block; a lower die boss for positioning the metal plate is arranged on the lower die platform, a horizontal punching cavity is arranged inside the lower die boss, and an upper wedge-shaped block corresponding to the lower wedge-shaped block in a bevel fit manner is arranged on the upper die baseplate. The punching die is novel in structure and can punch a workpiece in a horizontal direction perpendicular to the punching direction through a wedge-shaped matching principle so as to complete multidirectional processing through one time of punching sequentially, so that processing efficiency is improved greatly, and processing cost is lowered.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a stamping die for metal plates. Background technique [0002] Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] With the rapid development of the economy, automobiles have become the main means of transportation for people, and what follows is the vigorous development of the automobile industry. Due to the limitation of the use environment, auto parts need to have high manufacturing precision and assembly precision. Therefore, the sta...
