Problems solved by technology

However, during the stamping process of the sheet metal material, the deformation temperature of the sheet metal material will increase, and it will be easily bonded to the surface of the mold at some points due to the huge unit pressure, which will aggravate the deformation of the mold. Wear and scratches on the surface of the workpiece will seriously affect the service life of the mold and the quality of the stamping parts

Embodiment 1

[0028] Such as Figure 1-3 As shown, a sheet metal stamping forming device includes a mounting frame 1, an upper template 2 and a lower template 3 are arranged on the mounting frame 1, a punch 4 is provided on the upper template 2, and a punch 4 is provided on the lower template 3 A die 5 is arranged on the top, an outer guide column 22 and an outer guide sleeve 23 are arranged between the upper template 2 and the lower template 3, and the outer guide column 22 and the outer guide sleeve 23 play a corresponding guiding role, and the punch 4 and the An inner guide post 24 and an inner guide sleeve 25 are also provided between the dies 5. The inner guide post 24 and the inner guide sleeve 25 can prevent the center of the die 5 from being coincident with the punch 4, resulting in deformation of the die. The outside of the mold 4 is provided with a layer of insufficient oxidation lubricating film 6, and the punch 4 includes the following percentage materials: C: 0.9; Si: 0.5; Mn: ...

Embodiment 2

[0030] Such as Figure 4-5As shown, a stamping and forming device for sheet metal parts, this embodiment has the same parts as Embodiment 1, the difference is that: the side of the mounting frame 1 is also provided with a first cleaning device, and the first cleaning device includes The second telescopic device 11, one end of the second telescopic device 11 is connected with a cleaning plate 12, the inside of the cleaning plate 12 is provided with a rotating motor 13, and the output section of the rotating motor 13 is provided with a rotating shaft 14, and the rotating shaft 14 extends to the surface of the cleaning plate 12, one side of the rotating shaft 14 is connected with a magnetic rod 15, and the other side of the rotating shaft 14 is connected with a brush rod 16, the magnetic rod 15 can adopt a magnet or an electromagnet, the second The telescoping device 11 can move the cleaning plate 12 to the bottom of the punch 4, and the rotating shaft 14 is driven to rotate by t...

Embodiment 3

[0032] Such as Image 6 As shown, in this embodiment, the shape of the punch 4 is further improved, and the sheet metal part 29 is prone to rebound after stamping, causing the angle of distortion of the sheet metal part 29 to change, which is inconsistent with the mold. The upper side walls of the mold 4 are arranged inclined inwardly to form a certain angle. On both sides of the deformation groove 18, there are additional subsidy workpieces 28 such as hard rubber. The hard rubber can promote the sheet metal material to stick Hold the punch 4, after the mold is released, the sheet metal material rebounds, and both sides return to the vertical state, ensuring that the bending angle of the sheet metal part 29 will not change.

Abstract

The invention discloses a sheet metal part punch forming device which comprises a mounting frame, an upper die plate and a lower die plate are arranged on the mounting frame, a male die is arranged on the upper die plate, a female die is arranged on the lower die plate, an outer guide column and an outer guide sleeve are arranged between the upper die plate and the lower die plate, and a layer of insufficient oxidation lubricating film is arranged outside the male die. The die can be prevented from being bonded with a plate, die abrasion is reduced, and the service life of the die is prolonged.

Description

technical field [0001] The invention belongs to the technical field of stamping, and in particular relates to a stamping forming device for sheet metal parts. Background technique [0002] Sheet metal parts use the fluidity and ductility of materials to perform technological processes such as blanking, stretching, and bending on sheet metal materials to produce products of various shapes. At present, with the development of sheet metal CNC equipment, a large number of electronic sheet metal parts are manufactured using thin plates processed by CNC punching machines and CNC bending machines, which is a typical sheet metal structure. In order to process excellent sheet metal parts, it is necessary to combine the actual production and fully consider the processing accuracy and processing capacity of the dies and tools of sheet metal CNC processing equipment, as well as the process methods of stamping, bending, welding and surface treatment. Among them, the mold is one of the m...
