Description

Technical Field

[0001] The utility model relates to a cutting and forming stamping die, belonging to the technical field of stamping dies. Background Art

[0002] The 452 fixed contact is a functional part on a switch. Its material is 1mm thick tin bronze strip. The 452 fixed contact needs to be bent into a 90-degree forming state. Since the bending edge is too short, the bending edge is lengthened and the lengthened edge is cut by wire cutting to meet the part size requirements. This is not suitable for mass production, has low production efficiency and high part cost. Utility Model Content

[0004] The utility model is realized through the following technical solutions.

[0005] The utility model provides a cutting and forming stamping die, comprising an upper die and a lower die; the upper die comprises an upper die seat, the upper end face of the upper die seat is connected with a die handle, and the lower end face is sequentially connected with an upper pad, an upper lining plate, and a fixed plate; guide pillars are provided on both sides of the fixed plate, and a cutting punch is connected to the middle of the fixed plate; a limiting punch is provided on one side of the cutting punch, and the limiting punch is connected to the upper die seat through a spring; the lower die comprises a lower die seat, the upper end face of the lower die seat is sequentially connected with a lower pad and a concave die plate, and a positioning concave die insert and a concave die forming insert are provided in the concave die plate.

[0006] The upper end surface of the concave template is provided with a positioning groove.

[0007] The positioning die insert and the die forming insert are arranged in the positioning groove.

[0008] The cutting punch and the die forming insert work in cooperation.

[0009] The guide pin and the concave plate work in cooperation.

[0010] The beneficial effects of the utility model are: preventing displacement of parts during cutting and forming, meeting part size requirements, improving part production efficiency and size consistency; being able to improve mold use safety and the cutting and forming of stamping parts, and extending the service life of mold parts.

[0016] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0017] like Figure 3 and 4 As shown, a cutting and forming stamping die comprises an upper die and a lower die; the upper die comprises an upper die base 2, the upper end face of the upper die base 2 is connected with a die handle 1, and the lower end face is sequentially connected with an upper pad 3, an upper lining plate 5, and a fixed plate 7; guide pillars 6 are provided on both sides of the fixed plate 7, and a cutting punch 9 is connected to the middle of the fixed plate 7; a limiting punch 8 is provided on one side of the cutting punch 9, and the limiting punch 8 is connected to the upper die base 2 through a spring 4; the lower die comprises a lower die base 14, the upper end face of the lower die base 14 is sequentially connected with a lower pad 13 and a concave die plate 12, and a positioning concave die insert 10 and a concave die forming insert 11 are provided in the concave die plate 12.

[0018] The upper end surface of the concave template 12 is provided with a positioning groove.

[0019] The positioning die insert 10 and the die forming insert 11 are arranged in the positioning groove.

[0020] The cutting punch 9 and the die forming insert 11 work in coordination.

[0021] The guide pillar 6 and the concave mold plate 12 work in coordination.

[0022] The working principle of the utility model is:

[0023] 1. The operator uses tweezers to vertically place the part in the positioning die insert 10 of the concave die plate 12 of the lower die, and positions the part in shape through the positioning groove;

[0024] Second, step on the pedal on the press, the upper die moves downward, the spring 4, the limiting punch 8, the cutting punch 9 and the guide pillar 6 move downward, first the guide pillar 6 enters the concave die plate 12 for guidance, then the limiting punch 8 contacts the lower positioning concave die insert 10 and limits the part at the same time;

[0025] 3. The upper die continues to move downward, and the cutting punch 9 and the guide pillar 6 continue to move downward under the action of the press;

[0026] Fourth, the upper die continues to move downward, and the limiting punch 8 compresses the spring 4 until the limiting punch 8 contacts and limits the upper liner 5, and at the same time, the cutting punch 9 and the die forming insert 11 cut and bend the parts under the force;

[0027] 5. After the upper die moves upward, the limiting punch 8 with a spring 4 installed on the upper side returns to its original state under the action of the spring 4. The operator uses tweezers to remove the parts from the positioning die insert 11 to obtain the cut-off 452 fixed contact piece, such as Figures 1-2 shown.
