Example Embodiment

[0038] Example 1

[0039] See Figure 1-8 , Is a schematic diagram of the overall structure of a method for hierarchical stamping and forming of automotive sheet metal connectors. A method for hierarchical stamping and forming of automotive sheet metal connectors includes the following steps:

[0040] S1. Blank installation: install the blank to be stamped and formed on the stamping and forming device, install and position the blank to be stamped and formed, and wait for the stamping and forming device to press and form the blank to be stamped, wherein the stamping and forming device is provided by the present invention Graded stamping forming device for automobile sheet metal connectors;

[0041] S2, flanging stamping, stamping both sides of the blank that has been installed and positioned in step S1, bending the two sides of the blank to form flanging, and obtaining the flanging blank;

[0042] S3. Bending and stamping, performing secondary stamping on the blank that has been flang...

Abstract

The invention discloses a graded punch forming method for an automobile sheet metal connecting piece, and relates to the technical field of punch machining. The graded punch forming method comprises the following steps that S1, a blank is mounted, specifically, the blank to be subjected to punch forming is mounted on a punch forming device, the blank to be subjected to punch forming is mounted andpositioned, and the blank to be subjected to punch forming is subjected to punch forming by the punch forming device; and S2, flanging and punching are carried out, specifically, the two sides of theblank which is mounted and positioned in the step S1 are punched, the two sides of the blank are bent to form flanges, and the blank after the flanges are obtained. According to the graded punch forming method, locking rods are symmetrically arranged on the two sides of the top end of a forming groove, when the blank is bent and punched, first supporting blocks on the two sides are moved away towards the two sides of a forming block, the blank falling into the forming groove is locked through the locking rods, so that the top end of the blank is pressed in the bending process of the blank, the blank is bent along the contour of the forming block, and the bending precision of the connecting piece is improved.

Description

technical field [0001] The invention relates to the technical field of stamping processing of automobile sheet metal parts, in particular to a method for stepwise stamping forming of automobile sheet metal connectors. Background technique [0002] Automobile sheet metal is a technical means of automobile repair. In this respect, automobile sheet metal is equal to automobile sheet metal repair. It refers to the repair of the car body after a car collision, that is, all the work except for the spraying work of anti-corrosion and decoration of the car body. , such as the analysis of car body damage, the measurement of car body, the shaping of car body sheet metal, stretch correction, stress relief welding, and the assembly and adjustment of car body accessories. [0003] Automobile sheet metal connectors mainly include rivets, bolts, high-strength bolts, welding rods, pivots (pins), and various hoops, which are used to connect components in two adjacent parts of the automobile....
