Description

Technical Field

[0001] The utility model relates to the technical field of rolled shaft sleeve processing, and more specifically, to a combined blanking die. Background Art

[0002] It is known that rolled sleeves refer to thin-walled sleeves rolled from bearing materials or steel strips coated with bearing materials. They are widely used in bearing support parts of various mechanical equipment to provide good friction performance, reduce wear and extend service life. During their production, the plates need to be punched out according to the length, size and shape structure required by the design. Currently, they are mainly processed using single dies and closed dies. For example, a single die is used to punch out one side first, and then the other side is punched out based on the punched side. The length and size of this method are adjustable. A closed die is used to punch out both sides at the same time.

[0003] In actual use, since a single punch die is processed in two steps, which wastes labor time, there are positioning deviations during manual placement, and it is not suitable for mass production; although a closed die is processed in one step and both sides are punched at the same time, the size is fixed, and each size requires a corresponding die. The mold manufacturing cost is too high and cannot meet the current production situation of a large variety of products; therefore, a combined blanking die is proposed as a further improvement to reduce processing time while also having dimensional adjustability and reducing the development cost of new products.

[0038] Among them, if the above template 1 is a horizontal plane, the extension direction of the first limiting slide 91 is the X-axis direction, and the direction perpendicular to the X-axis direction is the Y-axis direction. Then, the first limiting slide 91 can prevent the punch 3 from deflecting in the Y-axis direction when adjusting the size, resulting in excessive parallelism of the blanking sheet and affecting the product processing accuracy.

[0039] The second limiting groove 92 is provided on the upper surface of the lower template 2. The bottom of the die 5 slides on the second limiting groove 92. The bottom of the die 5 is engaged with the upper surface of the lower template 2.

The first T-shaped block 12 is fixedly connected to the punch 3 by a short bolt, and the second T-shaped block 13 is fixedly connected to the stripper plate 4 by a long bolt.

[0042] Among them, if the above template 1 is a horizontal plane, the extension direction of the first limiting slide 91 is the X-axis direction, and the direction perpendicular to the X-axis direction is the Y-axis direction, then when adjusting the size, the fasteners can be loosened, and then the first T-block 12 and the second T-block 13 can slide on the first limiting slide 91, so that the punch 3 and the stripper plate 4 can move to the corresponding position in the X-axis direction;

[0043] The lower template 2 is provided with a second T-shaped sliding groove 21 connected to the second limiting sliding groove 92. The second T-shaped sliding groove 21 is internally slidably connected to a third T-shaped block 22. The third T-shaped block 22 is locked in the second T-shaped sliding groove 21 by fasteners. The third T-shaped block 22 is fixedly connected to the die 5 by bolts.

[0044] Among them, if the lower template 2 is a horizontal plane, the extension direction of the second limiting slide 92 is the X-axis direction, and the direction perpendicular to the X-axis direction is the Y-axis direction, then when adjusting the size, the fastener can be loosened, and then the third T-block 22 can slide on the second limiting slide 92, so that the die 5 can be moved to the corresponding position in the X-axis direction;

[0045] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a spring 10 is fixedly mounted on the top of the stripper plate 4 , and the other end of the spring 10 is in contact with the upper template 1 .

[0046] Among them, the spring 10 is used to reset the stripper plate 4, thereby completing the stripping and pressing of the material; it can provide sufficient pressing force during processing to prevent the sheet from deflecting during processing, and at the same time prevent the sheet from being stuck on the punch 3 for unloading after processing.

[0047] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a limiting baffle 51 for limiting the sheet material is fixedly installed on the upper surface of the die 5;

[0048] The limiting baffle 51 on the die 5 is used to limit the testing of plates of different specifications, and can be quickly replaced and adjusted when replacing plates of different specifications.

[0049] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a boss 31 is fixedly installed at the bottom of the punch 3, so as to prevent the punch 3 from being offset due to force during punching, thereby improving the punching section accuracy and dimensional stability and improving product quality.
