Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and in particular to an integrated stamping structure for reverse folding and flattening. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. Stamping and forging both belong to plastic processing (or pressure processing), and are collectively referred to as forging and pressing.

[0003] In order to ensure that the workpiece does not deviate when using existing stamping equipment, a limiting mechanism is used. However, the limiting mechanism of the existing stamping equipment cannot be adjusted in size, making it difficult to adapt to stamping raw materials of different sizes. Therefore, in order to correct the above defects, we propose an integrated stamping structure of reverse folding and flattening. Summary of the Invention

[0012] 1. By setting up a limiting frame, an electric telescopic rod, a first limiting plate, and a second limiting plate, the stamping part is placed on the stamping die.

[0025] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides an integrated anti-folding and flattening stamping structure, including a housing 1. A support plate 2 is fixedly connected to the inner wall of the housing 1. A stamping die 3 is provided above the support plate 2. Two anti-folding blocks 4 are fixedly connected to the inner wall of the stamping die 3. A hydraulic cylinder 5 is fixedly connected to the inner wall of the housing 1. A pressure plate 6 is provided below the output shaft of the hydraulic cylinder 5. A stamping block 7 is fixedly connected to the bottom of the pressure plate 6. Two vertical blocks 8 are fixedly connected to the top of the support plate 2. A limit frame 9 is fixedly connected to the top of the two vertical blocks 8. Two pairs of electric telescopic rods 10 are fixedly connected to the outer wall of the limit frame 9. The output shafts of the two pairs of electric telescopic rods 10 pass through the side wall of the limit frame 9 and are respectively fixedly connected to a first limit plate 11 and a second limit plate 12.

[0027] In the technical solution of this application embodiment, the stamping die 3 can be replaced by unscrewing the first bolt 14 through the setting of the first bolt 14 and the stamping die 3. The stamping die 3 has a horizontal block 13 fixedly connected to both sides of the side wall, and the first bolt 14 passes through the horizontal block 13. The top of the support plate 2 is provided with a threaded groove that matches the first bolt 14. The output shaft of the hydraulic cylinder 5 is fitted with a limiting sleeve 15. The bottom of the limiting sleeve 15 is fixedly connected to the top of the pressure plate 6, and two second bolts 16 pass through the limiting sleeve 15. The output shaft of the hydraulic cylinder 5 is provided with a threaded groove that matches the second bolts 16.

[0028] In the technical solution of this application embodiment, the vibration amplitude of the support plate 2 is reduced by setting the shock absorber 17, thereby improving the stability of stamping of the stamping part. The side wall of the stamping die 3 is provided with anti-slip texture. Several shock absorbers 17 are fixedly connected between the support plate 2 and the inner wall of the box 1. Several shock absorbers 17 are equidistantly distributed at the bottom of the support plate 2. The two vertical blocks 8 are symmetrically arranged about the central axis of the limiting frame 9.

[0029] Working principle: During use, the stamping part is placed on the stamping die 3. The electric telescopic rod 10 is activated, which pushes the two first limiting plates 11 and the second limiting plate 12 to move, thereby adjusting the distance between the two pairs of first limiting plates 11 and second limiting plates 12 to accommodate the size of the stamping part and limit the stamping part, preventing it from sliding on the stamping die 3 during stamping and improving the stamping stability. When stamping is required, the hydraulic cylinder 5 is activated, which pushes the pressure plate 6 downward. The pressure plate 6 drives the stamping block 7 downward, thus stamping the stamping part downward. During the stamping process, the stamping part is folded back. Block 4 causes the stamped part to fold upwards and reduces the vibration amplitude of the support plate 2 through the shock absorber 17, thereby improving the stamping stability. When it is necessary to replace the pressure plate 6 and the stamping block 7, unscrew the second bolt 16, remove the limit sleeve 15, pressure plate 6 and stamping block 7, and then put the limit sleeve 15 on the new pressure plate 6 onto the output shaft of the hydraulic cylinder 5, and then tighten the second bolt 16 again to complete the replacement of the pressure plate 6. When it is necessary to replace the stamping die 3, unscrew the first bolt 14, remove the stamping die 3, place the stamping die 3 on the support plate 2, and tighten the first bolt 14 again to complete the replacement of the stamping die 3.
