Description

Technical Field

[0001] The utility model relates to the field of punching dies, in particular to a single-step composite die for producing gaskets. Background Art

[0002] Metal gaskets are often used in various box bases. Their raw materials are generally long flat steel, and the middle position of such metal gaskets often needs to be punched for installation. In order to accurately fix the gasket, high requirements are placed on the accuracy of the punching. The existing process requires the cooperation of the punching die and the cutting die to complete the three process steps of feeding, punching, and cutting. The mold overhead is large, the operating cost is high, and there are safety hazards when manually picking up and placing parts. The punching quality is also average. Modern automated processing equipment requires that the punching die must have the ability to complete the punching and cutting operations in a single step. Therefore, it is necessary to design a composite mold that can complete the gasket processing in one step. Utility Model Content

[0003] The utility model aims to provide a single-step composite mold for producing a gasket, so as to solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted is:

[0005] A single-step composite mold for gasket production, consisting of a punch and a die, the punch includes an upper die seat, a fixed pad fixed below the upper die seat, a stripper plate installed below the fixed pad, a punching needle passing through the stripper plate, and the stripper plate and the punch are clearance-matched; when punching, the punching needle shuttles through the middle of the stripper plate, and also includes a cutting punch installed in front of the punching needle, and the cutting punch is also clearance-matched with the stripper plate, and the punching needle and the cutting punch are both installed on the fixed pad; the die includes a lower die insert corresponding to the position of the punching needle, a positioning device fixed on the lower die insert, a lower die seat fixed under the lower die insert, and a blanking box in front of the lower die seat, and the positioning device is located on both sides of the material strip. After the raw material of the workpiece is cut by the cutting punch, the finished gasket falls into the blanking box in front.

[0006] A specific improvement is that the positioning device is a positioning pin or a positioning block, and the number of the positioning device is at least one group.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model reduces the investment in related molds, shortens the stamping process and operators, eliminates potential safety hazards, and improves production efficiency and punching quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0016] Example: See Figure 1 and Figure 2 , a single-step composite mold for gasket production, consisting of a male mold and a female mold, the male mold includes an upper mold base, a fixed pad fixed below the upper mold base, a stripper plate 5 installed below the fixed pad, a punching needle 1 passing through the stripper plate 5, and the stripper plate 5 and the punching needle 1 are clearance-matched; it also includes a cutting punch 2 installed in front of the punching needle 1, and the cutting punch 2 and the stripper plate 5 are also clearance-matched. The punching needle 1 and the cutting punch 2 are both installed on the fixed pad, and the punching needle 1 and the cutting punch 2 shuttle between the stripper plate 5 during punching; the female mold includes a lower mold insert 6 corresponding to the position of the punching needle 1, a positioning pin (not shown) fixed on the lower mold insert 6, a lower mold base fixed under the lower mold insert 6, and a blanking box 4 in front of the lower mold base, and the positioning pins are located on both sides of the material strip. The gasket 7 is cut by the cutting punch 2 and falls into the blanking box 4 in front.

[0017] like Figure 3 As shown, the gasket 7 processed in this embodiment is a square thin sheet with a mounting hole in the middle.
