Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal part processing, and relates to a stamping deformation mechanism for the production and processing of automobile sheet metal parts. Background Technique

[0002] Sheet metal is a comprehensive cold processing technology for metal thin plates, and the products processed by sheet metal technology are called sheet metal parts. The processing of sheet metal parts includes shearing, stamping, welding, splicing, forming, etc. Among them, stamping is a forming processing method that applies external force to plates, strips, tubes, profiles, etc. by a press and a die, so that they produce plastic deformation or separation, so as to obtain workpieces (stamped parts) with the required shape and size.

[0003] A sheet metal part punching die disclosed in Chinese Patent CN217964324U includes a lower die base and an upper die base. If the sheet metal part is irregular in shape, a lower die needs to be used for support. The lower die can be placed on the lower die base, and the clamping rod is rotated to make the clamping seat clamp and fix the lower die. If the sheet metal part is of a relatively regular shape (such as a flat plate with a flat bottom surface), the lower die can be directly placed on the lower die base without using the lower die, and the clamping rod is rotated to make the clamping seat clamp and fix the sheet metal part, reducing the situation of frequently replacing the lower die.

[0004] When this punching die is in use, it is necessary to operate the clamping seat to fix lower dies of different sizes. When stamping several sheet metal parts with fixed shapes, the number of lower dies to be used is fixed. Therefore, when replacing the lower die, the clamping rod needs to be rotated multiple times for disassembly or fixation, and the use is not convenient enough.

[0005] To solve the above problems, the utility model proposes a stamping deformation mechanism for the production and processing of automobile sheet metal parts. Content of the Utility Model

[0006] To solve the problems in the background technique, the utility model proposes a stamping deformation mechanism for the production and processing of automobile sheet metal parts.

[0007] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: it includes a support frame, a punching head is arranged at the top of the support frame, a placement plate is fixedly connected to the bottom of the support frame, a groove is opened on the top surface of the placement plate, stepped protrusions are arranged at the four corners of the groove, rounded corners are opened on the side edges of the stepped protrusions, and chamfers are arranged on the side edges of the top surface of the groove.

[0008] Further, the support frame includes a top plate and a bottom plate, the top plate and the bottom plate correspond up and down, support rods are fixedly connected to the four corners of the bottom surface of the top plate, and the bottom ends of the support rods are fixedly connected to the top surface of the bottom plate;

[0009] The placement plate is fixedly arranged inside the bottom plate, and the top surface of the placement plate is flush with the top surface of the bottom plate.

[0010] Further, the protrusions at each corner in the groove are each composed of several rectangular blocks with different lengths, and the several rectangular blocks are fixedly connected in sequence to form a stepped shape.

[0011] Further, the stamping head includes a cylinder and a stamping rod. The stamping rod is fixedly connected to the bottom end of the cylinder, and both the cylinder and the stamping rod are arranged vertically.

[0012] A driving component is arranged on the top plate of the support frame, and the driving component drives the stamping head to slide horizontally back and forth above the groove.

[0013] Further, the driving component includes a lead screw. Installation plates are fixedly connected to both ends of the bottom surface of the top plate. The lead screw is rotatably connected between the two installation plates. A motor is fixedly connected to one side of one of the installation plates, and the motor drives the lead screw to rotate.
