Description

Technical Field

[0001] The present application relates to the field of punching machines, and in particular to a sheet metal punching device. Background Art

[0002] The stamping machine drives the flywheel through an electric motor, and drives the crank-connecting rod mechanism through the clutch and transmission gear to make the slider move up and down, driving the stretching die to form the steel plate. It is often used for processing sheet metal parts. When a conventional stamping machine is in use, after the stamping machine is connected to the power supply, the required die plate is installed in the stamping machine, and the sheet metal to be processed is installed on the upper end of the die plate with the help of a clamp. The stamping machine controls the stamping plate to stamp the sheet metal part.

[0003] With respect to the above-mentioned related technologies, the inventors believe that conventional clamps mostly use components such as bolts to fix sheet metal parts. When processing large quantities of sheet metal parts, conventional clamp fixing methods require a lot of time, thereby affecting the working efficiency of the stamping machine.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

The punching machine 1 controls the punching plate 3 to punch the sheet metal, and the fixing frame 4 is installed on the surface of the punching machine 1. A slider 6 is slidably connected in the slide groove 5 on the inner wall of the fixing frame 4. A limit frame 7 is rotatably installed on the surface of the slider 6, and a spring 9 is installed between the slider 6 and the limit frame 7. The limit frame 7 is pushed by the spring 9 to keep the limit frame 7 to limit the sheet metal, so that the limit frame 7 is stuck on the surface of the sheet metal to fix the sheet metal, and when disassembling, the handle 8 on the surface of the limit frame 7 is pulled to disassemble the sheet metal.

[0021] Reference Figure 2 The surface of the slider 6 is slidably connected to the slide groove 5 in the fixing frame 4, so that the position of the limit frame 7 on the top of the slider 6 can be adjusted, which is convenient for fixing sheet metal parts of different sizes and effectively improves the application scope of the device. An auxiliary plate 10 made of rubber material is installed at one end of the limit frame 7. The friction between the limit frame 7 and the sheet metal part is improved with the help of the auxiliary plate 10, thereby improving the fixing effect of the device and avoiding the problem of the sheet metal part being offset due to slipping between the limit frame 7 and the sheet metal part.

[0022] Reference Figure 3 - Figure 4 The stripping plate 11 is installed in the die plate 2, and a pull block 12 is installed at one end of the stripping plate 11. After the sheet metal is processed, the stripping plate 11 is rotated by the pull block 12 to lift the sheet metal on the top of the stripping plate 11, which is convenient for removing the sheet metal compacted on the surface of the die plate 2, and is more convenient in use.

[0024] An auxiliary plate 10 made of rubber material can also be installed at one end of the limit frame 7, so as to increase the friction between the limit frame 7 and the sheet metal with the help of the auxiliary plate 10, thereby improving the fixing effect of the device, and the stripping plate 11 is installed in the die plate 2, and a pull block 12 is installed at one end of the stripping plate 11, so that after the sheet metal is processed, the stripping plate 11 can be driven to rotate with the help of the pull block 12, so as to facilitate the removal of the sheet metal compacted on the surface of the die plate 2, which is more convenient when used.
