Description

Technical Field

[0001] The utility model relates to a stamping die, in particular to an adjustable contact stamping die. Background Art

[0002] Contacts are important components of various electrical switches and safety electrical switches. They are mainly used to connect or disconnect the internal circuit of the switch. The contacts are generally stamped and formed by a mold. The structure of a traditional pressing mold mainly includes an upper die and a lower die. A forming punch is fixedly arranged in the upper die, and a forming die cooperating with the forming punch is arranged in the lower die. The upper die is controlled to descend so that the forming punch cooperates with the forming die to realize the pressing and forming of the contacts. The defects of this structure are: since the forming punch is fixed and its overall length cannot be changed, its stamping thickness is certain. However, according to the use requirements of switches of different specifications, the thickness of contacts of the same forming shape may be different. Moreover, according to different use requirements, some contacts may need to be fully punched out of the outline, while some contacts only need to be punched out of the depression. This requires replacing molds with different processing thicknesses to realize the stamping and forming of contacts of different specifications, resulting in poor flexibility and versatility in the use of molds.

[0015] As shown in the figure, the utility model discloses an adjustable contact stamping die, including an upper die 16 and a lower die 4. The upper die 16 is connected to a first lifting drive assembly. In this embodiment, the first lifting drive assembly includes a first oil cylinder 13, and the piston rod of the first oil cylinder 13 is connected to the upper die 16. An upper mold plate 8 and an upper lifting seat 11 are movably arranged in the upper die 16. The upper mold plate 8 is connected to a first lifting adjustment component. The first lifting adjustment component includes a first screw rod 9. The first screw rod 9 is screwed to the upper mold plate 8. A first guide component is arranged corresponding to the upper mold plate 8. By controlling the rotation of the first screw rod 9, the upper mold plate 8 can be driven to adjust its height. In addition, the first screw rod 9 is connected to the output end of the first motor 12 to realize electric adjustment of the height. The upper lifting seat 11 is connected to a second lifting adjustment component. The second lifting adjustment component includes a second screw rod 15. The second screw rod 15 is screwed to the upper lifting seat 11. A second guide component is arranged corresponding to the upper lifting seat 11. By controlling the rotation of the second screw rod 15, the upper lifting seat 11 can be driven to adjust its height. In addition, the second screw rod 15 is connected to the output end of the second motor 14 to realize electric adjustment of the height. The upper lifting seat 11 is connected to the upper and lower ends to realize electric adjustment. A forming convex die 17 is arranged at the bottom of the upper lifting seat 11. A first clearance groove for the forming convex die 17 to pass through is arranged on the upper template 8. A lower die seat 5 cooperating with the upper template 8 is arranged on the lower die seat 5. A forming concave die groove 7 cooperating with the forming convex die 17 is arranged on the lower die 4. A lower lifting seat 3 is movably arranged in the lower die 4. The lower lifting seat 3 is connected to the third lifting adjustment component. The third lifting adjustment component includes a third screw 2. The third screw 2 is screwed with the lower lifting seat 3. A third guide component is arranged corresponding to the lower lifting seat 3. By controlling the rotation of the third screw 2, the lower lifting seat 3 can be driven to move and adjust its height. Further, the third screw 2 is connected to the output end of the third motor 1. A clearance hole 10 for the first screw 9 to pass through is arranged on the upper lifting seat 11 for realizing electric adjustment. A positioning molding die 6 that can be partially inserted into the molding concave die groove 7 is arranged on the top of the lower lifting seat 3. The bottom of the molding convex die 17 can be matched with the positioning molding die 6. A positioning column 18 is provided at the bottom of the upper mold plate 8, and a positioning groove 19 is provided on the lower mold base 5 to cooperate with the positioning column 18, so as to ensure that the upper mold plate 8 and the lower mold base 5 can be accurately matched during stamping.

[0016] The working principle of the utility model is: the metal contact substrate to be punched is sent between the upper template 8 and the lower die base 5, and then the first oil cylinder 13 is controlled to drive the upper die 16 to descend, so that the upper template 8 and the lower die base 5 press the contact substrate to the required thickness, and the upper template 8 can be controlled to rise and fall to adjust its height, thereby adjusting the pressed thickness, and at the same time, the forming punch 17 descends and extends into the forming die groove 7 and abuts against the forming positioning die 6 to achieve full punching or pressing out a depression of the required shape, which specifically depends on the height position set by the forming punch 17 and the forming positioning die 6.

[0017] The structure of the utility model, by setting the upper template as a liftable structure, can realize the pressing of contact materials of different thicknesses by adjusting the height of the upper template and cooperating with the lower die base. At the same time, a liftable forming punch and a positioning forming die are adopted. According to the stamping requirements, full punching processing of the contour can be performed, or a depression of the required shape can be semi-punched. There is no need to frequently replace the mold, which effectively improves its flexibility of use.
