Metal plate pressure tank bending die

Abstract

The invention discloses a metal plate pressure tank bending die which comprises an upper die plate, a lower die plate, a guide post device, a male die, a female die component and projecting strips. The upper die plate is connected with the lower die plate through the guide post device, the male die is arranged below the upper die plate, the female die component is arranged on the lower die plate and comprises two female die blocks, a bottom plate and positioning blocks, the bottom plate is arranged between the two female die blocks, the height of each female die block is larger than that of the bottom plate, the positioning blocks are arranged on the female die blocks, the projecting strips are arranged on the lower surface of the male die close to two ends of the female die blocks, and connecting angles of the inner slide faces and the upper surfaces of the female die blocks are circular angles. The metal plate pressure tank bending die is fine in punching effect, high in punching efficiency and suitable for batch punching and does not easily rebound, and punching quality is improved.

Description

technical field [0001] The invention relates to a bending die, in particular to a sheet metal groove bending die used in bending and forming a sheet metal. Background technique [0002] Made as attached figure 1 When the two rounded corners of the bottom are right-angled U-shaped brackets, the attached figure 2 Raw sheet metal shown is bent. In the past, due to the influence of equipment factors, manual bending was usually used, but such work is too difficult, time-consuming and laborious, and the bending effect is poor. With the development of society and the advancement of technology, the bending can be realized by bending the template, and the operation of the bending mold reduces the difficulty of work and saves time and effort. However, the previous bending molds tend to cause the raw material sheet metal to break during the bending process, and the bent brackets are also prone to rebound, resulting in poor bending quality, and can only handle small quantities of pr...

Problems solved by technology

However, the previous bending molds tend to cause the raw material sheet metal to break during the bending process, and the bent brackets are also prone to rebound, resulting in poor bending quality, and can only handle small quantities of production. When dealing with mass production, the bending efficiency cannot be guaranteed
