Description

Technical Field

[0001] The utility model relates to the technical field of wave spring stamping, in particular to a stamping device for producing wave springs. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. There are many types of springs. According to their shapes, they mainly include spiral springs, scroll springs, leaf springs, special-shaped springs, etc. Wave springs are called wave springs for short. They are elastic elements with several peaks and valleys on a thin metal ring. They are usually used in situations where the load and deformation are not large, and the spring stiffness is required to be small and an axial preload needs to be applied. The wave spring stamping device in the prior art mainly includes a workbench and a stamping assembly located above the workbench. A forming die matching the shape of the wave spring is provided on the workbench. The forming material is placed on the forming die. The stamping assembly moves downward and cooperates with the forming die to stamp out a wave spring. In this processing method, since the single-layer wave spring is thin, the stamped wave spring is located in the forming die and is difficult to remove. Utility Model Content

Detailed implementation manners

[0023] Next, in combination with the accompanying drawings in the embodiments of the present utility model, where the stamping tool head 6 and the shearing tool head 13 are driven by a hydraulic device, and the turntable 15 and the coil conveying wheel 16 are driven by a motor to rotate, which are not shown in the drawings, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] As shown in the attached Figure 1 to the attached Figure 5 As shown, a stamping device for producing wave springs includes a coil rack 1. There is a turntable 15 on the coil rack 1. The turntable 15 is rotatably connected to the coil rack 1. A fixed shaft 17 is provided at the center of the turntable 15. A coil conveying wheel 16 is provided on one side of the turntable 15. A stamping table 2 is provided directly in front of the coil rack 1. A cylinder 3 is provided in the stamping table 2. A shearing seat 5 is provided on the cylinder 3 outside the stamping table 2. A through feed channel 4 is provided in the cylinder 3 and the shearing seat 5. A movable stamping tool head 6 is provided on one side of the shearing seat 5, and a forming table 7 is provided on the other side. A forming die 8 is provided on the forming table 7. The stamping tool head 6 passes through the shearing seat 5 and cooperates with the forming die 8. A receiving bin 9 is provided between the forming table 7 and the shearing seat 5.

[0026] With the above structure, the coil on the turntable 15 rotates the turntable 15. Under the action of the coil conveying wheel 16, the material is fed into the interior of the cylinder 3 along the feed channel 4. When it moves to the shearing seat 5, the tool assembly slides on the stamping table 2 to shear the material, and then pushes the material onto the forming table 7 for extrusion to form a wave shape. The tool retracts, and the wave spring falls into the receiving bin 9.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1

[0029] The stamping tool head 6 includes a round convex platform tool head 10. The round convex platform tool head 10 is installed on a base tool head 11. The outer ring of the forming die 8 is a protruding wave-shaped ring 12. The center of the forming die 8 is a groove that cooperates with the round convex platform tool head 10. A shearing tool head 13 is provided outside the forming table 7. The shearing tool head 13 is slidably connected to the base 14 on the stamping table 2. The shearing tool head 13 contacts the outer end of the shearing seat 5 during the sliding process.

[0030] With the above structure, when the material reaches the shearing seat 5, the stamping cutter head 6 slides on the stamping table 2. The round boss cutter head 10 on the stamping cutter head 6 first contacts the material, punches a through hole in the material, and then withdraws. The waste hole pieces fall through the opening at the bottom of the shearing seat 5. Then, the stamping cutter head 6 continues to cut the material to cut out a round piece with a through hole. Since the center of the stamping cutter head 6 coincides with the center of the irregular groove of the forming table 7, and there is a hole in the middle of the irregular groove that matches the small round table, the round piece with the through hole hangs on the stamping cutter head 6. The stamping cutter head 6 presses the round piece into the forming die 8 to form a waveform. After the stamping cutter head 6 retracts, because the round piece deforms and contacts the side wall of the shearing seat 5, the waveform spring drops, and the shearing cutter head 13 moves to cut off the waste material protruding outside the shearing seat 5.

[0031] The specific usage method is as follows: Place the coil to be processed on the turntable 15 of the coil rack 1. The fixed shaft 17 rotates to send the coil from the feeding channel 4 in the cylinder 3 to the shearing seat 5. The stamping cutter head 6 on one side of the shearing seat 5 moves. The centers of the through holes on the stamping cutter head 6, the shearing seat 5, and the wave-shaped ring 12 on the forming table 7 are on the same horizontal line. The round boss cutter head 10 on the stamping cutter head 6 first punches holes in the coil. The stamping cutter head 6 withdraws from the shearing seat 5, and the waste hole pieces fall along the opening at the bottom of the shearing seat 5. The stamping cutter head 6 continues to advance to cut out the required iron sheet, squeezes the iron sheet onto the forming table 7 to press out a waveform, and the stamping cutter head 6 retracts to its original position. Because the iron sheet deforms and retracts to contact the side wall of the shearing seat 5, it will fall into the receiving bin 9. At this time, the shearing cutter head 13 slides on the stamping table 2, and the shearing cutter head 13 can cut off the waste material leaking outside the shearing seat 5.
