Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] 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 stamping dies. A metal sheet stamping die comprises a lower die and an upper die paired with the lower die. The lower die comprises a lower die base plate and a lower die table fixed to the lower die base plate. The upper die comprises an upper die base plate and an upper die table fixed to the upper die base plate. The upper die table is correspondingly matched with the lower die table. A lower die boss for positioning a metal sheet is arranged at the upper end of the lower die table, and the lower die table is internally provided with a longitudinal punching cavity and a longitudinal die cutting cavity. The upper die table comprises an upper die seat plate fixed to the upper die base plate, a longitudinal punching column, a longitudinal die cutting column and an upper die compression plate movably arranged on the longitudinal punching column and the longitudinal die cutting column, wherein the longitudinal punching column and the longitudinal diecutting column are fixed to the upper die seat plate. The longitudinal punching column and the longitudinal die cutting column correspond to the longitudinal punching cavity and the longitudinal diecutting cavity respectively. The stamping die can conduct trimming and punching processes on the metal sheet simultaneously, the machining efficiency is improved, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to stamping dies for sheet metal. 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 stamp...
