Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal, in particular to a sheet metal bending forming die. Background Art

[0002] Sheet metal is generally made by manually or by die stamping some thin metal plates to produce plastic deformation to form the desired shape and size, and can be further formed into more complex parts through welding or a small amount of mechanical processing. In the process of sheet metal bending, different requirements for workpieces lead to the need to use different molds to process the workpieces. Existing molds can usually only bend and shape sheet metal into one shape, and the function is relatively single. The mold can only be disassembled and replaced in turn before the sheet metal is bent again. It is inconvenient to operate the tool to disassemble the mold, and the mold cannot be quickly installed and disassembled, which reduces production efficiency. Utility Model Content

[0026] When a worker holds the first rotating disk 14 and rotates the first rotating disk 14 , the first rotating disk 14 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the bending plate 13 to rotate toward one side of the arc groove 11 .

[0027] Example 2

[0028] Reference Figure 1-7 , which is the second embodiment of the utility model, is based on the previous embodiment. Specifically, a servo motor 16 is installed in the top wall of the fixed block 15, and a first threaded shaft 17 extending to the top of the top wall of the fixed block 15 is installed on the top wall of the servo motor 16, and a pressure plate 18 is threadedly connected to the upper end of the first threaded shaft 17.

[0029] When the servo motor 16 is started, the servo motor 16 drives the first threaded shaft 17 to rotate, and the first threaded shaft 17 drives the pressing plate 18 to move up and down through the threaded connection with the pressing plate 18 .

[0030] Example 3

[0031] Reference Figure 1-7 , which is the third embodiment of the utility model, and this embodiment is based on the above two embodiments. In use, the top wall of the pressing plate 18 is fixedly provided with a support plate 19, and the side wall of the support plate 19 close to the symmetry center is provided with a sliding groove 20;

[0034] A cam block 25 is fixedly disposed on the bottom wall of the lifting plate 23 , and the cam block 25 is located just above the arc-shaped slot 11 .

[0035] In this way, the worker places the sheet metal piece on the top wall of the base 10, the servo motor 16 is started, the servo motor 16 drives the first threaded shaft 17 to rotate, and the first threaded shaft 17 drives the pressing plate 18 to move downward through the threaded connection with the pressing plate 18 until the bottom walls of the two pressing plates 18 press against the sheet metal piece placed on the top wall of the base 10, the two pressing plates 18 fix one end of the sheet metal piece, and extend the end of the sheet metal piece that needs to be bent to the top of the top wall of the bending plate 13;

[0036] The worker holds the first rotating disk 14 and rotates the first rotating disk 14, the first rotating disk 14 drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the bending plate 13 to rotate toward one side of the arc groove 11, and the bending plate 13 drives the sheet metal piece above the top wall of the bending plate 13 to rotate toward one side of the arc groove 11 and bend the sheet metal piece;
