Description

Technical Field

[0001] This utility model relates to the field of stamping positioning auxiliary technology, specifically to a stamping positioning auxiliary device for sheet metal parts. Background Technology

[0002] In the sheet metal stamping process, the accuracy of positioning directly determines the dimensional accuracy, shape accuracy, and adaptability of the stamped parts for subsequent assembly. In particular, the positioning accuracy of the upper and lower stamping dies directly affects the quality of the stamped sheet metal parts.

[0003] A search revealed a patent, CN222198655U, which discloses a sheet metal stamping positioning auxiliary device, comprising: a base plate; a first movable block controllably connected to the top of the base plate, capable of lateral linear displacement relative to the base plate; a connecting block disposed between the first movable block and the base plate; positioning bolts forming a locking and positioning structure between the first movable block and the base plate; a second movable block controllably connected to the first movable block, capable of lateral linear displacement relative to the first movable block, with the displacement direction perpendicular to the displacement direction of the first movable block; and a tooling groove disposed on the second movable block for accommodating the sheet metal part to be stamped. This utility model can solve the problem of high equipment cost and slow production efficiency caused by the rigid and fixed assembly position of the stamping machine molds during some existing sheet metal stamping processes, which prevents flexible adjustment of the stamping fit between different molds and punches.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

Through slots 5 adapted to the clamping seats 4 are provided through opposite sides of the mounting frame 3. Two symmetrical clamping plates 6 are provided on the sides of the clamping seats 4. The clamping seats 4 can move laterally and vertically within the mounting frame 3. The two clamping plates 6 on one side of the clamping seats 4 can move synchronously towards or away from each other. The two clamping seats 4 and four clamping plates 6 are clamped on multiple sides of the mounting frame 3. First sliding blocks 7 are slidably connected to opposite sides of the mounting frame 3. A first adjusting threaded rod 8 is threaded through and threaded onto the first sliding block 7. One end of the first adjusting threaded rod 8 is rotatably connected to one side of the clamping seat 4. The upper mold 2 has a threaded connection with a first limiting nut 9. The upper mold 2 has a first sliding groove 10 on each of its opposite sides that is adapted to the first sliding block 7. The mounting frame 3 has a second adjusting threaded rod 11 that extends into the first sliding groove 10 and is rotatably connected to one side. The second adjusting threaded rod 11 passes through the first sliding block 7 and is threadedly connected to it. The outer end of the second adjusting threaded rod 11 is threadedly connected to a second limiting nut 12. The clamping plate 6 has a third sliding block 13 that is fixedly installed on one side. The clamping seat 4 has a third sliding groove 14 that is adapted to the third sliding block 13 and is rotatably connected to one side. The clamping seat 4 has a third adjusting threaded rod 15 that extends into the third sliding groove 14 and is rotatably connected to one end. The third adjusting threaded rod 15 passes through the two third sliding blocks 13 and is threadedly connected to them. The side of the third adjusting threaded rod 15 is threadedly connected to a third limiting nut 16.

[0031] In this embodiment, the mounting frame 3 is fixedly installed on the stamping table of the existing stamping device. The stamping column 23 is located on the stamping device and is used to drive the upper die 2 to move up and down. The upper die 2 is installed at the lower end of the stamping column 23. The lower die 1 is placed in the mounting frame 3 and located between the two clamping seats 4. Then, the stamping device drives the stamping column 23 to move down, and the upper die 2 moves down to the upper part of the lower die 1. The upper die 2 engages with the lower die 1, and the lower die 1 and the upper die 2 are aligned. The position of the clamping seat 4 is adjusted by rotating the first adjusting threaded rod 8. The side of the clamping seat 4 is in close contact with the opposite side of the lower die 1. The lateral position of the lower die 1 is adjusted by rotating the two first adjusting threaded rods 8. Then, the third adjusting threaded rod 15 is rotated. The threads of the third adjusting threaded rod 15 on the inner side of the third sliding groove 14 are symmetrical and opposite. When rotating, the two clamping plates 6 are driven to move towards each other simultaneously. The two clamping plates 6 clamp and fix the longitudinal side of the clamping seat 4. By rotating the second adjusting threaded rod 11, the first sliding block 7 can be moved within the first sliding groove 10. When the first sliding block 7 moves, it drives the clamping seat 4 to move. The through groove 5 is used to make room for the clamping seat 4 and adjust the horizontal and vertical position of the lower die 1. The second limiting nut 12 is locked to limit and fix the position of the first sliding block 7. The two clamping seats 4 and the four clamping plates 6 can position the lower die 1 of different sizes and can move the clamping seat 4 horizontally and vertically within the mounting frame 3, thus improving the applicability of the sheet metal stamping positioning auxiliary device. The lower die 1 is provided with a positioning groove, which is adapted to the size of the sheet metal part to be stamped. The upper die 2 is driven to move down by the stamping column 23 to stamp the sheet metal part.
