Description

Technical Field

[0001] This utility model relates to the field of screw heading technology, specifically to a screw heading forming device. Background Technology

[0002] Screw head forming equipment is a core specialized piece of equipment used in the screw manufacturing process to form the screw head, and it plays an irreplaceable role in the fastener production field. The process typically involves pre-treating metal wire (such as steel wire) and then feeding it into a stamping machine. Through the coordinated operation of the stamping seat and the punch, the end of the wire is stamped multiple times, causing the end of the wire to undergo plastic deformation under pressure, ultimately forming a screw head shape that meets the design requirements, such as cross groove, internal hexagon, round head, and other different styles.

[0003] As a core component in screw head forming equipment that directly contacts the wire and bears the stamping force, the shape and condition of the working surface of the stamping seat directly affect the forming quality of the screw head. In actual production, due to the differences in the shape of screw heads of different types and specifications, or the wear and deformation of the working surface of the stamping seat after long-term stamping operations, it is often necessary to maintain and replace the stamping seat to ensure the production quality and efficiency of the screws.

[0004] In existing screw heading forming equipment, the stamping seat is usually fixed to the worktable by bolts. When the stamping seat needs to be replaced, the operator needs to use tools to rotate multiple bolts in sequence to install and remove the stamping seat, which is inefficient. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a screw head forming device to solve the technical problem of low replacement efficiency of stamping seats in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a screw heading forming device, including a stamping machine, a worktable provided on the stamping machine, and further including a mounting base, a stamping base, and a positioning mechanism. The mounting base is fixedly disposed on the worktable and has a mounting groove. The stamping base is disposed on one side of the worktable, and a mounting plate is fixedly disposed at the bottom end of the stamping base. The mounting plate extends into the mounting groove and is slidably connected to the side wall of the mounting groove. The positioning mechanism is disposed in the mounting base and is used to position the mounting base and the mounting plate.

[0007] Preferably, the positioning mechanism includes a positioning groove, a first cavity, a positioning seat, a relative movement mechanism, and a limiting mechanism. Two positioning grooves are formed on each of the two opposite sidewalls of the mounting plate, and the positioning grooves penetrate the top sidewall of the mounting plate. The first cavity is formed within the mounting seat, and an L-shaped first positioning channel is formed on the top sidewall of the first cavity on one side of the positioning groove. Two positioning seats are slidably disposed within the first cavity, and two positioning blocks are fixedly disposed on the top sidewall of each positioning seat. The positioning blocks extend into the first positioning channel. The relative movement mechanism is disposed within the mounting seat to drive the two positioning seats to move relative to each other. The limiting mechanism is disposed on the positioning blocks to limit the movement between the positioning blocks and the mounting plate.

[0008] Furthermore, the relative movement mechanism includes a bidirectional screw and a first handwheel. The bidirectional screw is rotatably disposed in the first cavity and passes through the two positioning seats through a threaded connection. The first handwheel is rotatably disposed on the mounting seat and is fixedly connected to the bidirectional screw.

[0009] Furthermore, the limiting mechanism includes a second cavity, a limiting plate, and a moving mechanism. The second cavity is formed within the positioning seat, and an L-shaped second positioning channel is formed on the top side wall of the second cavity. The second positioning channel passes through the positioning block. The limiting plate is slidably disposed within the second cavity, and two L-shaped limiting blocks are fixedly disposed on the limiting plate. The limiting blocks pass through the second positioning channel and extend out of the positioning block. The moving mechanism is disposed within the positioning seat and is used to drive the limiting plate to move within the second cavity.

[0010] Furthermore, the moving mechanism includes a threaded rod, a third cavity, a second bevel gear, and a driving mechanism. The threaded rod is rotatably disposed within the second cavity and passes through the limiting plate via a threaded engagement. The positioning seat is located on one side of the second cavity and has the third cavity. A first bevel gear is rotatably disposed on the inner bottom wall of the third cavity and is fixedly connected to the threaded rod. A second bevel gear is rotatably disposed on the inner wall of the third cavity and meshes with the first bevel gear. The driving mechanism is disposed on the mounting base and is used to drive the second bevel gear to rotate.

[0011] Based on the above scheme, the driving mechanism includes a driving port, a driving prism, and a second handwheel. The driving port is opened on the side wall of the positioning seat. The driving prism is rotatably disposed in the first cavity. The driving prism passes through the driving port and the second bevel gear. The second bevel gear is slidably connected to the driving prism. The second handwheel is rotatably disposed on the mounting seat and is fixedly connected to the driving prism.

[0012] Based on the above scheme, a guide rod is fixedly installed in the first cavity, and the guide rod passes through the positioning seat and is slidably connected to the positioning seat.

[0013] Based on the above scheme, a rubber pad is fixedly provided on the side wall of the limiting block.

[0014] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, by setting up a positioning mechanism, after the mounting plate is inserted into the mounting groove, the rotation of the first handwheel can drive the bidirectional screw to rotate. At the same time, the bidirectional screw and the positioning seat are threaded together to drive the positioning seat to move relative to each other. Then, the movement of the positioning seat can drive the positioning block and the limiting block to move. This allows the limiting block to be inserted into the positioning groove, and the mounting plate and the stamping seat are fixed by the cooperation between the limiting block and the positioning groove. At the same time, the stamping seat can be disassembled by rotating the first handwheel in the opposite direction, which facilitates the replacement of the stamping seat. 2. In this utility model, by setting a limiting mechanism, after the limiting block is inserted into the positioning groove, the rotation of the second handwheel can drive the drive prism to rotate. At the same time, the sliding engagement between the drive prism and the second bevel gear drives the second bevel gear to rotate. Then, the meshing between the second bevel gear and the first bevel gear drives the first bevel gear and the threaded rod to rotate. Thus, the threaded engagement between the threaded rod and the limiting plate drives the limiting plate and the limiting block to move and drive the limiting block to press against the side wall of the limiting groove. This facilitates the improvement of the installation stability of the mounting plate and the stamping seat through the engagement between the limiting block and the bottom of the mounting groove.

[0024] like Figures 1-6 As shown, this invention illustrates a screw heading forming device according to one embodiment of the present invention, including a stamping machine 1, a worktable 2 on the stamping machine 1, a mounting base 3, a stamping base 5, and a positioning mechanism. The mounting base 3 is fixedly mounted on the worktable 2 and has a mounting groove 4. The stamping base 5 is located on one side of the worktable 2, and a mounting plate 6 is fixedly mounted on the bottom end of the stamping base 5. The mounting plate 6 extends into the mounting groove 4 and is slidably connected to the side wall of the mounting groove 4. The positioning mechanism is located in the mounting base 3 and is used to position the mounting base 3 and the mounting plate 6.

[0025] Reference Figures 1-4The positioning mechanism includes a positioning groove 7, a first cavity 8, a positioning seat 10, a relative movement mechanism, and a limiting mechanism. Two positioning grooves 7 are formed on each of the two opposite sidewalls of the mounting plate 6, penetrating the top sidewall of the mounting plate 6. The first cavity 8 is located within the mounting base 3. An L-shaped first positioning channel 9 is formed on the top sidewall of the first cavity 8, located on one side of the positioning groove 7. Two positioning seats 10 are slidably disposed within the first cavity 8. Two positioning blocks 11 are fixedly disposed on the top sidewall of the positioning seats 10, extending into the first positioning channel 9. The relative movement mechanism is located within the mounting base 3 and is used to drive the two positioning seats 10 to move relative to each other. The limiting mechanism is located on the positioning blocks 11 and is used to limit the movement between the positioning blocks 11 and the mounting plate 6. The relative movement mechanism includes a bidirectional screw 12 and a first handwheel 13. The bidirectional screw 12 is rotatably disposed within the first cavity 8. The bidirectional screw 12 is connected to the mounting plate 6 via a screw... The threaded engagement between the two positioning seats 10 and the first handwheel 13 is rotatably mounted on the mounting seat 3. The first handwheel 13 is fixedly connected to the bidirectional screw 12. A guide rod 24 is fixedly mounted in the first cavity 8. The guide rod 24 passes through the positioning seat 10 and is slidably connected to the positioning seat 10. Specifically, after the mounting plate 6 is inserted into the mounting groove 4, the rotation of the first handwheel 13 can drive the bidirectional screw 12 to rotate. At the same time, the threaded engagement between the bidirectional screw 12 and the positioning seat 10 drives the positioning seat 10 to move relative to each other. Then, the movement of the positioning seat 10 can drive the positioning block 11 and the limiting block 25 to move. This allows the limiting block 25 to extend into the positioning groove 7. The engagement between the limiting block 25 and the positioning groove 7 can realize the installation and fixation of the mounting plate 6 and the stamping seat 5. At the same time, rotating the first handwheel 13 in the opposite direction can realize the disassembly of the stamping seat 5, which facilitates the replacement of the stamping seat 5.

[0026] Reference Figures 3-6The limiting mechanism includes a second cavity 14, a limiting plate 16, and a moving mechanism. The second cavity 14 is located within the positioning seat 10. An L-shaped second positioning channel 15 is formed on the top side wall of the second cavity 14, penetrating the positioning block 11. The limiting plate 16 is slidably disposed within the second cavity 14. Two L-shaped limiting blocks 25 are fixedly disposed on the limiting plate 16, penetrating the second positioning channel 15 and extending out of the positioning block 11. The moving mechanism is located within the positioning seat 10 and is used to drive the limiting plate 16 to move within the second cavity 14. The moving mechanism includes a threaded rod 17, a third cavity 18, a second bevel gear 20, and a driving mechanism. The threaded rod 17 is rotatably disposed within the second cavity 14 and penetrates the limiting plate 16 through a threaded connection. The positioning seat 10 has a third cavity 18 located on one side of the second cavity 14. The inner bottom wall of the third cavity 18 rotates. A first bevel gear 19 is provided, which is fixedly connected to a threaded rod 17. A second bevel gear 20 is rotatably mounted on the inner wall of the third cavity 18 and meshes with the first bevel gear 19. A drive mechanism is mounted on the mounting base 3 to drive the second bevel gear 20 to rotate. A rubber pad is fixedly provided on the side wall of the limiting block 25. Specifically, the operation of the drive mechanism can drive the second bevel gear 20 to rotate. At the same time, the meshing of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 and the threaded rod 17 to rotate. Thus, the threaded engagement between the threaded rod 17 and the limiting plate 16 can drive the limiting plate 16 and the limiting block 25 to move and drive the limiting block 25 to press against the side wall of the limiting groove. This facilitates the installation stability of the mounting plate 6 and the stamping seat 5 through the engagement between the limiting block 25 and the bottom of the mounting groove 4.

[0027] Reference Figures 4-6 The driving mechanism includes a driving port 21, a driving prism 22, and a second handwheel 23. The driving port 21 is located on the side wall of the positioning seat 10. The driving prism 22 is rotatably disposed in the first cavity 8. The driving prism 22 passes through the driving port 21 and the second bevel gear 20. The second bevel gear 20 is slidably connected to the driving prism 22. The second handwheel 23 is rotatably disposed on the mounting seat 3. The second handwheel 23 is fixedly connected to the driving prism 22. Specifically, after the limiting block 25 is inserted into the positioning groove 7, the driving prism 22 can be rotated by the rotation of the second handwheel 23. At the same time, the second bevel gear 20 can be rotated by the sliding engagement relationship between the driving prism 22 and the second bevel gear 20.

[0028] In this embodiment, during use, the operator selects a suitable stamping seat 5 and inserts the mounting plate 6 into the mounting groove 4. Then, the operator rotates the first handwheel 13, which drives the bidirectional screw 12 to rotate. Simultaneously, the threaded engagement between the bidirectional screw 12 and the positioning seat 10 causes the positioning seat 10 to move relative to the operator. This movement of the positioning seat 10 then moves the positioning block 11 and the limiting block 25, allowing the limiting block 25 to extend into the positioning groove 7. The engagement between the limiting block 25 and the positioning groove 7 secures the mounting plate 6 and the stamping seat 5. Reversing the first handwheel 13 allows for the disassembly of the stamping seat 5, facilitating its removal. 5. Replacement is performed. After the limiting block 25 extends into the positioning groove 7, the rotation of the second handwheel 23 can drive the drive prism 22 to rotate. At the same time, the sliding engagement between the drive prism 22 and the second bevel gear 20 drives the second bevel gear 20 to rotate. Then, the meshing between the second bevel gear 20 and the first bevel gear 19 drives the first bevel gear 19 and the threaded rod 17 to rotate. Thus, the threaded engagement between the threaded rod 17 and the limiting plate 16 drives the limiting plate 16 and the limiting block 25 to move and drive the limiting block 25 to press against the side wall of the limiting groove. This facilitates the improvement of the installation stability of the mounting plate 6 and the stamping seat 5 through the engagement between the limiting block 25 and the bottom of the mounting groove 4.
