[0002] A gasket is a mechanical seal between two objects, usually used to prevent leakage between the two objects due to pressure, corrosion and natural thermal expansion and contraction of the pipeline. Since the machined surface cannot be perfect, gaskets can be used to fill the irregularities. Gaskets are usually made of flaky materials such as metal, glass fiber or plastic polymers. Figure 3 The structure of a friction-reducing gasket for automobiles in the prior art is shown. At present, the molding method of the friction-reducing gasket is to complete the processes of punching holes, punching strip holes, cutting and molding on the corresponding molds respectively. However, the inventor of the present application found through actual production operation that the method of completing the molding of different parts through corresponding molds is not only time-consuming and inefficient, but also has high design and manufacturing costs for different corresponding molds, which seriously restricts the large-scale batch production of the friction-reducing gasket, and it is urgent to solve this problem. Utility Model Content

The utility model provides a anti-friction gasket forming device for automobiles.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A friction-reducing pad forming device for automobiles comprises a feeding mechanism, a lower mold and an upper mold, wherein the feeding mechanism transfers the sheet material to be formed to the lower mold and the upper mold at a fixed distance, the lower mold comprises a lower mold plate and a lower pad, a lower outer guide column is fixedly provided on the lower mold plate, a lower inner guide hole and two rows of material guide columns are fixedly provided on the lower pad, the two rows of material guide columns are arranged in parallel along the length direction of the lower pad and each material guide column can be telescoped up and down, the upper mold comprises an upper mold plate and an upper pad, an upper outer guide cylinder sleeved with the lower outer guide column is provided on the upper mold plate, an upper inner guide column matched with the lower inner guide hole and a material guide column avoidance hole matched with the material guide column are fixedly provided on the upper pad, and the upper pad on the inner side of the material guide column and the upper pad on the inner side of the material guide column avoidance hole have a length along the upper edge A first punching mechanism, a punching and chamfering mechanism, a second punching mechanism, a tapping mechanism, an idle step mechanism and a cutting and forming mechanism are sequentially arranged in the degree direction. The first punching mechanism punches an abutting hole in the center of the sheet material and a positioning hole at the edge of the material. The punching and chamfering mechanism uses the positioning hole to position the material and chamfers the abutting hole mouth after punching. The second punching mechanism uses the positioning hole to position the material and punches a strip hole in the center of the material after the abutting hole is chamfered. The tapping mechanism uses the positioning hole to position the material and taps the abutting hole after the chamfer. The idle step mechanism does not operate the material after tapping. The cutting and forming mechanism uses the positioning hole to position the material, bends and cuts the material after the idle step operation, and cuts off the positioning hole on the edge of the material.

After alignment, the sheet material sent is punched with abutment holes in the center of the material and positioning holes at the edge of the material by the first punching mechanism, and then the upper mold rises; then, the sheet material to be formed is continuously transferred to the lower mold and the upper mold at a fixed distance by the feeding mechanism, and the upper mold descends and closes with the lower mold to align and position the material. After alignment, the abutment hole is chamfered by the punching and chamfering mechanism, and then the upper mold rises; then, the sheet material to be formed is continuously transferred to the lower mold and the upper mold at a fixed distance by the feeding mechanism, The upper mold descends, closes and aligns with the lower mold and positions the material.

After alignment, the material is bent and cut by the cutting and forming mechanism, and the positioning holes on the edge of the material are cut off, and then the upper mold rises, thereby obtaining the anti-friction gasket for automobiles of the present application. It can be seen that the aforementioned mechanisms of the present application are actually carried out continuously and simultaneously in the working process, that is, in one stroke, these mechanisms are designed in sequence at several different positions of the mold, and can complete multiple processes at the same time. The friction-reducing gasket can be formed on a pair of molds. Therefore, it not only saves time and has high processing efficiency, but also has relatively low mold design and production costs, which is conducive to large-scale batch production of the friction-reducing gasket.

The lifting and lowering of the upper mold 3 can be driven by the existing hydraulic cylinder, and its specific control is a mature existing technology; the lower pad 22 inside the guide column 222 and the upper pad 32 inside the guide column avoidance hole are sequentially equipped with a first punching mechanism, a punching chamfering mechanism, a second punching mechanism, a tapping mechanism, an empty step mechanism and a cutting and forming mechanism along the length direction.

[0023] Compared with the prior art, when the automobile anti-friction gasket forming device provided by the utility model is working, the sheet material to be formed is first sent to the lower mold and the upper mold through the feeding mechanism, and the sheet material to be formed is placed between the two rows of guide columns on the lower pad; then the upper mold descends and closes with the lower mold, and the upper and lower molds are aligned through the cooperation of the lower outer guide column and the upper outer guide cylinder and the lower inner guide hole and the upper inner guide column. After alignment, the sheet material sent is punched with abutment holes in the center of the material and positioning holes at the edge of the material by the first punching mechanism, and then the upper mold rises; then the sheet material to be formed is continuously transferred to the lower mold and the upper mold at a fixed distance through the feeding mechanism, and the upper mold descends and closes with the lower mold to align and position the material.

After alignment, the material is bent and cut by the cutting and forming mechanism, and the positioning holes on the edge of the material are cut off, and then the upper mold rises, thereby obtaining the anti-friction gasket for automobiles of the present application. It can be seen that the aforementioned mechanisms of the present application are actually carried out continuously and simultaneously in the working process, that is, in one stroke, these mechanisms are designed in sequence at several different positions of the mold, and can complete multiple processes at the same time. The friction-reducing gasket can be formed on a pair of molds. Therefore, it not only saves time and has high processing efficiency, but also has relatively low mold design and production costs, which is conducive to large-scale batch production of the friction-reducing gasket.

[0024] As a specific example, please refer to Figure 2 As shown, the feeding mechanism 1 includes a servo motor 11 and a support rod 12, the output shaft of the servo motor 11 is fixedly connected to a feeding shaft 13, the support rod 12 is rotatably connected to the feeding shaft 13, and the circumferential surfaces of the two feeding shafts 13 are relatively bonded with a sandwich glue 14, thereby pre-clamping and placing the sheet material to be formed between the sandwich glue 14 of the two feeding shafts 13, and then starting the servo motor 11, under the rotation of the output shaft of the servo motor 11, the two feeding shafts 13 can be driven to rotate, so that under the clamping friction between the sheet material and the sandwich glue 14, the sheet material to be formed is transferred to the lower mold and the upper mold at a fixed distance.

[0025] As a specific example, please refer to Figure 1 As shown, a material guide groove 223 is provided on the circumferential surface of each material guide column in the two rows of material guide columns 222, and the height of the material guide column above the material guide groove 233 is equal to the depth of the material guide column avoidance hole. Therefore, after the material guide column 222 above the material guide groove 233 is avoided through the material guide column avoidance hole, the two sides of the sheet material to be formed between the two rows of material guide columns 222 can be placed just in the material guide groove 223, and the rear bottom surface just contacts with the surface of the lower pad 22, thereby achieving better positioning and guiding effect on the sheet material to be formed.

[0026] As a specific example, please refer to Figure 1 As shown, the first punching mechanism includes a stop hole punch 41 and a positioning hole punch 42 fixedly arranged on the upper pad 32, and corresponding stop hole punch holes 43 and positioning hole punch holes 44 are arranged on the lower pad 22. Therefore, when the stop hole punch 41 and the positioning hole punch 42 on the upper pad 32 are pressed onto the lower pad 22, a stop hole can be punched out in the center of the sheet material to be formed and a positioning hole can be punched out at the edge of the material.

[0027] As a specific example, please refer to Figure 1 As shown, the lower pad 22 is also fixed with an anti-skid pattern protrusion 224, and the upper pad 32 is correspondingly fixed with an anti-skid pattern pressing block (not shown in the figure), so that anti-skid patterns can be formed on the sheet material to be formed while punching the abutment holes and the positioning holes.

[0028] As a specific example, please refer to Figure 1 As shown, the punching and chamfering mechanism includes a chamfering tool 51 fixedly arranged on the upper pad 32 and a positioning column 91 passing through the positioning hole, and the chamfering tool hole 52 and the positioning column hole 92 are correspondingly arranged on the lower pad 22. Therefore, when the chamfering tool 51 on the upper pad 32 punches the lower pad 22, the hole mouth after punching can be chamfered, and the positioning column 91 and the positioning column hole 92 can be inserted and matched to ensure accurate operation of chamfering the hole mouth.

Among them, the tapping device 71 can be implemented by the mechanical tapping equipment of Panqi Company.

[0031] As a specific embodiment, the idle step mechanism does not operate on the material after tapping, and correspondingly, no structural features are set on the upper pad 32 and the lower pad 22 to act on the material. The idle step mechanism is set between the tapping mechanism and the cutting and forming mechanism mainly to increase the assembly space of the parts between the two steps of the tapping mechanism and the cutting and forming mechanism.

[0032] As a specific example, please refer to Figure 1 As shown, the cutting and forming mechanism includes a material cutting tool (not shown in the figure) fixedly arranged on the upper pad 32, a material bending punch 81 and a positioning column 91 passing through the positioning hole, and the corresponding material cutting tool groove 82, material bending punch groove 83 and positioning column hole 92 are arranged on the lower pad 22.

The present application simultaneously sets the positioning column 91 and the positioning column hole 92 in the punching and chamfering mechanism, the second punching mechanism, the tapping mechanism and the cutting and forming mechanism, mainly to ensure the accuracy of each process, thereby improving the forming accuracy of the anti-friction gasket.
