The purpose of the utility model is to design a flanging forming fixture that can accurately process parts that meet the size and can quickly clamp and fix the workpiece, thereby shortening the processing time and improving production efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by this utility model is:

[0005] A fixture for flanging the ends of copper alloy gasket ring stamping parts includes a fixture body composed of a front splint and a rear splint spliced together. The front splint is provided with a front semicircular clamping groove, and the rear splint is provided with a rear semicircular clamping groove. The front semicircular clamping groove and the rear semicircular clamping groove are relatively spliced together to form a circular clamping groove for clamping the gasket ring. The front splint and the rear splint are spliced together through a positioning structure and then clamped on a vise for fixation.

[0006] To further define the above solution, the thickness of the front and rear plates and the depth of the circular clamping groove formed by the front and rear semicircular clamping grooves are equal to the height of the straight portion in the height direction of the gasket.

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0018] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0019] See also Figure 1-4 , describe in detail the embodiments of the present utility model.

[0020] Example: Fixture for forming the flanges at both ends of copper alloy gasket stamping parts, see Figure 1 As shown, the clamp body is composed of a front clamping plate 1 and a rear clamping plate 2 which are spliced together front and back. The front clamping plate 1 is provided with a front semicircular clamping groove 3, and the rear clamping plate 2 is provided with a rear semicircular clamping groove 4. The front semicircular clamping groove 3 and the rear semicircular clamping groove 4 are relatively spliced together to form a circular clamping groove for clamping the gasket 9. The front clamping plate 1 and the rear clamping plate 2 are spliced together through a positioning structure and clamped on a vise for fixation.

[0021] In this embodiment, a plurality of circular clamping grooves can be provided in a clamp body, and two or more workpieces can be clamped at a time, which can effectively improve productivity.

[0022] In a specific embodiment, the thickness of the front and rear plates 1 and 2 and the depth of the circular groove formed by the front and rear semicircular grooves 3 and 4 are equal to the height of the straight portion in the height direction of the gasket 9 .

[0023] In the above structure, the depth of the circular clamping groove is equal to the height of the straight part in the height direction of the gasket that does not need to be flanging. When the gasket blank is clamped in the circular clamping groove, it can ensure that the two ends of the blank used for forming the flanging are placed outside the groove, which is convenient for flanging.

[0024] In a specific embodiment, the front splint 1 is provided with a front splint seat 5 at both ends, and the rear splint 2 is provided with a rear splint seat 6 at both ends. The front splint seat 5 and the rear splint seat 6 are both provided with positioning holes 7, and the positioning holes 7 on the front splint seat 5 and the rear splint seat 6 on the same side are connected by a positioning pin 8.

[0025] The above structure can ensure that the front and rear splints are quickly positioned and assembled together, thereby improving work efficiency.

[0026] In a specific embodiment, see Figure 3 and 4As shown, it also includes a lower punch 10 and an upper punch 11. The lower punch 10 is placed directly below the circular clamping groove of the clamp body and its upper end is placed in the lower end hole of the stamped blank of the gasket 9 for forming the flanging of the lower end of the gasket 9. The upper punch 11 is placed directly above the circular clamping groove of the clamp body and its lower end is placed in the upper end hole of the stamped blank of the gasket 9 for forming the flanging of the upper end of the gasket 9.

[0027] Preferably, there is a distance between the lower end surfaces of the front splint 1 and the rear splint 2 and the lower end surfaces of the front splint seat 5 and the rear splint seat 6, and the distance forms a placement space for the lower punch 10. The height a of the placement space is equal to the height of the lower punch 10 minus the height of the flange at one end of the gasket ring 9.

[0028] When using this fixture to process this type of gasket, use a vise to clamp it. During processing, open the front and rear clamps along the positioning pins, place the blank of the gasket in the circular clamping groove of the fixture body, close the front and rear clamps, configure a pad of appropriate height at the lower end of the vise mouth, place the lower punch in the placement space below the front and rear clamps, and extend the upper end of the lower punch into the lower hole of the blank. Adjust the position. At this time, the part of the lower punch that is higher than the placement space is the height of the flanging at the lower end of the part. Clamp the fixture body with the vise mouth, but do not clamp it tightly to ensure that the fixture can move. Place the upper punch in the upper hole of the blank and strike the upper punch with a hammer. When the upper punch is acted upon by external force, the lower punch extends into the open end of the blank. At this time, the entire fixture moves downward, and the bottom of the lower punch is flush with the outer end of the placement space, thus completing the flanging of the two ends of the blank.

[0029] The clamp of the utility model can accurately ensure the external dimensions of the parts, the blank can be quickly clamped by opening the clamp, and the parts can be conveniently taken out after processing and forming, which not only meets the performance and appearance quality of the product, but also effectively improves the qualified rate of the product.
