Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, specifically to a novel raw material cold heading machine for processing automotive hexagonal bolts. Background Technology

[0002] In the automotive manufacturing industry, hex bolts are key connecting components, and their machining accuracy and production efficiency directly affect the assembly quality and production capacity of the entire vehicle. Cold heading machines, with their cold plastic deformation processing characteristics on metal raw materials, can efficiently form the head and shank of hex bolts. Due to their advantages such as high material utilization and excellent product mechanical properties, they have become the core equipment in automotive hex bolt production. The stamping block is the core component of the cold heading machine for shaping raw materials. It works in conjunction with the punch to complete the upsetting of bolts. Since automotive hexagonal bolts come in different specifications (such as diameter, length, head size, etc.), the stamping block needs to be replaced accordingly to match the processing requirements during production changes. However, the replacement process of the stamping seat of the existing cold heading machine has many limitations: First, the connection between the stamping seat and the equipment base is mostly fixed with multiple sets of bolts. Disassembly and installation require tightening the bolts one by one, which is cumbersome and time-consuming, seriously affecting the efficiency of production changeover. Utility Model Content

The driving assembly is mounted on the fixed base and is used to drive the fourth bevel gear to rotate.

[0009] Based on the above scheme, the drive assembly includes a drive rod and an internal hex bolt head. The drive rod is fixedly mounted on the fourth bevel gear, and the end of the drive rod away from the fourth bevel gear extends out of the fixed seat.

[0020] like Figures 1-4 As shown, this invention illustrates a novel raw material cold heading machine for processing automotive hexagonal bolts according to one embodiment of the present invention. The machine includes a cold heading machine body 1, a worktable 2 mounted on the body 1, a fixed base 3, a stamping base 5, a first cavity 7, and a positioning mechanism. The fixed base 3 is fixedly mounted on the worktable 2 and has a fixed groove 4. The stamping base 5 is located on one side of the fixed base 3. A fixed ring 6 is fixedly mounted at the bottom end of the side wall of the fixed base 3.

The first threaded rod 14 is rotatably disposed within the adjustment port 10. The first threaded rod 14 passes through the adjacent adjustment seat 11 through threaded engagement. A connecting post is fixedly disposed on the first threaded rod 14, and the connecting post is located away from the first threaded rod 14. One end of the first bevel gear 15 is fixedly installed inside the second cavity 13. The second bevel gear 16 is rotatably mounted on the inner bottom wall of the second cavity 13. The second bevel gear 16 meshes with the first bevel gear 15. The rotating mechanism is mounted on the positioning plate 8 and is used to drive the second bevel gear 16 to rotate. Specifically, the operation of the rotating mechanism can drive the second bevel gear 16 to rotate. At the same time, the meshing of the second bevel gear 16 with the first bevel gear 15 drives the first bevel gear 15, the connecting column, and the first threaded rod 14 to rotate. Then, the first threaded rod 14 moves the adjusting seat 11 through the threaded engagement with the adjusting seat 11, thereby facilitating the adjustment of the position of the positioning block 12. After the fixing ring 6 is inserted into the fixing groove 4, the fixing ring 6 can be installed and fixed through the engagement of the positioning block 12 with the fixing groove 4, thereby facilitating the installation of the stamping seat 5. Afterwards, the stamping seat 5 can be disassembled by rotating the internal hexagon bolt head 24 in the opposite direction, thereby facilitating the replacement of the stamping seat 5.

[0022] Reference Figures 2-4The rotating mechanism includes a first drive port 17, a second drive port 18, a drive prism 19, and a drive mechanism. The first drive port 17 is located on the side wall of the second cavity 13, the second drive port 18 is located on the second bevel gear 16, and the drive prism 19 is rotatably disposed within the second cavity 13, passing through the first drive port 17 and the second drive port 18. The drive prism 19 is slidably connected to the side wall of the second drive port 18. The drive mechanism is mounted on the fixed base 3 and is used to control the rotation of the drive prism 19. The drive mechanism includes a third cavity 20, a fourth bevel gear 22, and a drive assembly. The third cavity 20 is located within the fixed base 3, and a third bevel gear 21 is rotatably disposed on the inner top wall of the third cavity 20. The third bevel gear 21 is fixedly connected to the drive prism 19, and the fourth bevel gear 22 is rotatably disposed on the side wall of the third cavity 20. The bevel gear 22 meshes with the third bevel gear 21. The drive assembly is mounted on the fixed base 3 and is used to drive the fourth bevel gear 22 to rotate. The drive assembly includes a drive rod 23 and an internal hex bolt head 24. The drive rod 23 is fixedly mounted on the fourth bevel gear 22, and the end of the drive rod 23 away from the fourth bevel gear 22 extends out of the fixed base 3. The internal hex bolt head 24 is fixedly mounted on the end of the drive rod 23 away from the fourth bevel gear 22. Specifically, the operator tightens the internal hex bolt head 24 with an internal hex wrench. At the same time, the drive rod 23 drives the fourth bevel gear 22 to rotate. Then, through the meshing of the fourth bevel gear 22 with the third bevel gear 21, the third bevel gear 21 and the drive prism 19 are driven to rotate. Thus, through the sliding engagement between the drive prism 19 and the second drive port 18, the second bevel gear 16 is driven to rotate.

[0023] Reference Figures 2-4 The fastening mechanism includes a second threaded rod 25, an annular groove 26, and a drive ring 28. Multiple second threaded rods 25 are rotatably disposed within the second cavity 13, and the second threaded rods 25 pass through the positioning disc 8 via threaded engagement. The annular groove 26 is formed on the side wall of the fixed seat 3. A first gear 27 is rotatably disposed within the annular groove 26 on one side of the second threaded rod 25, and the first gear 27 is fixedly connected to the adjacent second threaded rod 25. The drive ring 28 is rotatably disposed within the annular groove 26, and a first toothed ring 29 is fixedly disposed on the inner wall of the drive ring 28. The first toothed ring 29 and the first gear... The drive ring 28 has anti-slip texture on its side wall. Specifically, when the positioning block 12 extends into the fixing groove 4, the rotation of the drive ring 28 can drive the first gear ring 29 to rotate. In turn, the meshing of the first gear ring 29 with the first gear 27 drives the first gear 27 and the second threaded rod 25 to rotate. Thus, the threaded engagement of the second threaded rod 25 with the positioning disc 8 can drive the positioning disc 8 and the positioning block 12 to move. The movement of the positioning block 12 can press against the surface of the fixing ring 6, thereby improving the installation stability of the stamping seat 5.

[0024] In this embodiment, during use, the operator inserts the fixing ring 6 into the fixing groove 4, and then the operator tightens the hexagonal bolt head 24 using an Allen wrench. Simultaneously, the drive rod 23 drives the fourth bevel gear 22 to rotate. The meshing of the fourth bevel gear 22 with the third bevel gear 21 drives the third bevel gear 21 and the drive prism 19 to rotate. The sliding engagement between the drive prism 19 and the second drive port 18 drives the second bevel gear 16 to rotate. Simultaneously, the meshing of the second bevel gear 16 with the first bevel gear 15 drives the first bevel gear 15, the connecting column, and the first threaded rod 14 to rotate. Finally, the threaded engagement between the first threaded rod 14 and the adjusting seat 11 drives the adjusting seat 11. The positioning block 12 is moved to facilitate adjustment of its position. After the fixing ring 6 is inserted into the fixing groove 4, the fixing ring 6 is fixed by the cooperation between the positioning block 12 and the fixing groove 4, thus facilitating the installation of the stamping seat 5. Then, the operator rotates the drive ring 28, which drives the first toothed ring 29 to rotate. In turn, the meshing of the first toothed ring 29 with the first gear 27 drives the first gear 27 and the second threaded rod 25 to rotate. Thus, the threaded engagement between the second threaded rod 25 and the positioning plate 8 drives the positioning plate 8 and the positioning block 12 to move. The movement of the positioning block 12 can press against the surface of the fixing ring 6, thereby improving the installation stability of the stamping seat 5.
