Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to a stamping equipment for producing automobile clip springs. Background Art

[0002] Brake spring sheet stamping equipment is an automated stamping system specifically designed for producing spring sheets for automotive brake systems. This equipment typically includes a stamping device, a loading device, and a discharge device. The stamping device consists of a moving assembly and a drive mechanism, which are integrated into a frame. The drive mechanism controls the movement of at least two moving assemblies and utilizes a stamping die to secure and stamp the metal strip. For example, Chinese invention patent application publication number CN120001867A discloses a stamping device for automotive brake system spring sheets. The device primarily comprises a workbench with a mounting slot defined on its top. A stamping machine body is fixedly mounted directly above the workbench, and a top housing is fixedly mounted on top of the stamping machine body. When the bottom pressing block slides upward, a linkage rod within the top extrusion member drives a push-out post at one end of the extrusion block to slide downward along the bottom pressing block. The top extrusion member, in conjunction with the push-out member, pushes out any spring sheet stuck to the bottom pressing block, preventing the spring sheet from sticking to the bottom pressing block and thereby improving the production efficiency of the stamping device. This patent overcomes the problem that current spring leaf products are difficult to quickly detach from the module; however, this patent still has problems such as poor workpiece stamping stability and low equipment operating efficiency. In response to this, we have proposed a stamping equipment for the production of automotive spring leaf to solve the above problems. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-9 The present invention provides two technical solutions, specifically including the following embodiments: Example 1 In an embodiment of the present invention, a stamping device for producing automotive spring clips includes an upper die frame 1 and a lower die frame 2. A plurality of positioning rods 3 are fixed between the upper die frame 1 and the lower die frame 2. A forming bottom die 6 is fixedly installed inside the lower die frame 2. A load-bearing slide 14 is slidably installed inside the forming bottom die 6. A spring clip body 7 is placed above the load-bearing slide 14. The load-bearing slide 14 is slidably connected to the forming bottom die 6 and is used to support the spring clip body 7. A driving cylinder 5 is fixedly installed inside the upper mold frame 1, and the piston end of the driving cylinder 5 is fixedly connected to the stamping die 4. The stamping die 4 can move downward following the piston end of the driving cylinder 5 and press the retaining spring body 7 and the load-bearing slide 14 into the interior of the forming bottom mold 6 to realize the stamping operation.

[0020] During operation, the initial position of the load-bearing slide 14 is kept flush with the top of the lower die frame 2. By placing the clip spring body 7 to be formed just above the load-bearing slide 14, and then operating the driving cylinder 5, the stamping die 4 can be driven to move downward until the stamping die 4 contacts the clip spring body 7, and then the stamping die 4 continuously applies pressure to press the clip spring body 7 and the load-bearing slide 14 into the interior of the forming bottom die 6, completing the forming operation.

[0021] A bottom positioning frame 12 is fixedly installed inside the forming bottom mold 6, and a negative pressure device 13 is fixedly installed inside the bottom positioning frame 12. A bellows 142 is connected between the negative pressure device 13 and the load-bearing slide 14. The interior of the load-bearing slide 14 is hollow and a plurality of negative pressure adsorption holes 141 are symmetrically opened on the top. The plurality of negative pressure adsorption holes 141 can adsorb and position the spring sheet body 7 placed on the top of the load-bearing slide 14.

[0022] When the spring clip body 7 to be formed is placed directly above the load-bearing slide 14, the negative pressure device 13 is operated. The negative pressure device 13 can generate negative pressure inside the load-bearing slide 14 through the bellows 142, and through the cooperation of multiple negative pressure adsorption holes 141, the adsorption and positioning of the spring clip body 7 are completed until the spring clip body 7 is pressed into the forming bottom mold 6 to complete the stamping operation, thereby ensuring the stamping stability and accuracy of the spring clip body 7. At the same time, by filling gas into the inside of the load-bearing slide 14 when demolding, the load-bearing slide 14 can lift the spring clip body 7 through the negative pressure adsorption holes 141, completing the separation of the load-bearing slide 14 and the spring clip body 7, thereby improving the demolding effect and convenience, and further improving the working efficiency.

[0023] A plurality of telescopic rods 401 may be connected between the stamping die 4 and the upper die frame 1 .

[0024] A plurality of telescopic sleeves 15 can be connected between the load-bearing slide 14 and the interior of the lower mold frame 2, and a return spring 151 is installed inside the telescopic sleeve 15.

[0026] Among them, the side forming assembly includes a side driving frame 9, which is rotatably installed inside the corresponding concave groove 8, and the piston end of the side driving frame 9 is fixedly installed with a side forming frame 10. The interior of the lower mold frame 2 is fixedly installed with an angle adjustment module 901, and the piston end of the angle adjustment module 901 is rotatably connected to the end of the side driving frame 9, thereby driving the side driving frame 9 to adjust the angle.

[0027] When the stamping die 4 moves downward and presses the clip spring body 7 and the load-bearing slide 14 into the interior of the forming bottom die 6, the side driving frames 9 on both sides are operated to drive the side forming frames 10 to move horizontally toward the clip spring body 7 until they come into contact with the side forming frames 10 and push the side of the clip spring body 7 to perform the bending operation; by operating the angle adjustment module 901, the side forming frames 10 can be driven to rotate and the angle can be adaptively adjusted, further improving the convenience of equipment operation and the scope of application; The above-mentioned side drive frame 9 and angle adjustment module 901 are both existing electric cylinders, which are controlled based on the existing PLC control module and will not be described in detail here.

[0028] In addition, the end of the side drive frame 9 can be fixedly sleeved on the limiting frame 902, and the two sides of the limiting frame 902 are fixedly installed with a rotating shaft 903, and the rotating shaft 903 is rotatably installed inside the corresponding concave groove 8, thereby realizing the side drive frame 9 being rotatably installed inside the corresponding concave groove 8.

[0029] When the angle adjustment module 901 is in operation, the piston end of the angle adjustment module 901 drives the side driving frame 9 to rotate around the axis of the rotating shaft 903 to achieve angle adjustment of the side forming frame 10.

[0030] Example 2 Based on Example 1, in the embodiment of the present invention, a stamping device for producing automobile spring sheets is different from Example 1 in that: The side forming frames 10 on both sides are symmetrical to each other and can be translated along the central axis direction of the side driving frame 9 to achieve the bending operation of the clip spring body 7.
