Blanking device and method for intelligent printed board of automobile

Abstract

The invention discloses a blanking device and method for an intelligent printed board of an automobile. The device comprises a base (1) and a portal frame (2) fixedly arranged at the top of the base (1), a positioning groove (3) is formed in the top surface of the base (1), a through groove (4) penetrating through the bottom surface of the base (1) is formed in the groove bottom of the positioning groove (3), and the outer contour of the through groove (4) is matched with the outer contour of a groove body (21). Two pressing oil cylinders (5) are fixedly arranged on a cross beam of the portal frame (2), the two pressing oil cylinders (5) are arranged on the left side and the right side of the through groove (4) correspondingly, piston rods of the two pressing oil cylinders (5) penetrate through the cross beam, a pressing plate (6) is fixedly arranged between the acting ends of the two piston rods, the pressing plate (6) is arranged over the positioning groove (3), and a through hole (7) is formed in the pressing plate (6). The blanking device and method have the beneficial effects that the structure is compact, the blanking cost is reduced, the groove body forming efficiency is improved, and the consistency of machined products is ensured.

Description

technical field [0001] The invention relates to the technical field of punching grooves on printed boards for new energy vehicles, in particular to a punching device and method for intelligent printed boards of automobiles. Background technique [0002] With the continuous development of new energy vehicles, printed boards are installed in the electrical parts of new energy vehicles, and chips are installed on the printed boards, and the chips are used to control the actions of the hardware parts of the car. Among them, the structure of the automotive printed board is as follows: Figure 1~2 As shown, it includes a board body 20 and a groove body 21 disposed on the board body 20, and the groove body 21 is used for installing chips. Wherein, the tank body 21 is processed by a punching process, that is, the board body 20 is punched with a punching die to form the tank body 21 . However, although the blanking die can process the groove body 21 on the plate body 20, in the actu...

AI Technical Summary

Problems solved by technology

However, although the blanking die can process the groove body 21 on the plate body 20, in the actual production process, the following technical problems still occur: 1. The blanking area is large, that is, the punch of the blanking die must be punched at one time. When cutting a large area of ​​material, the punching force is too large, resulting in a large number of burrs around the tank body, resulting in the subsequent grinding of the burrs around the tank body 21, which undoubtedly increases the forming process of the tank body , thereby reducing the forming efficiency of the tank body

2. Due to the excessive punching force, the punch has not punched a few plates, and its cutting edge is passivated, so that only a new punch can be replaced, which undoubtedly increases the punching cost

3. Before each punching, it is necessary to draw a line on the surface of the plate body 20, that is, to draw the outer contour of the groove body 21, and then transport the plate body to the punching station, but manual marking not only increases the The work intensity of the workers, and the position of each line is deviated, resulting in inconsistent positions of the grooves on each product after processing
