[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 - Figure 5This utility model provides a multi-station cold heading machine with a mold quick positioning and locking device, including a multi-station cold heading machine 1. A fixing block 2 is fixedly connected to the top of the multi-station cold heading machine 1. A groove 3 is formed inside the fixing block 2. A connecting plate 33 is fixedly connected to the side wall of the groove 3. A motor 32 is provided on one side of the connecting plate 33. A bolt 34 is provided at the output end of the motor 32. A lifting block 31 is threadedly connected to the surface of the bolt 34. A support base 36 is fixedly connected inside the groove 3. A rotating shaft 37 is rotatably connected inside the support base 36. An irregular block 38 is sleeved on the surface of the rotating shaft 37. A connecting block 38 is fixedly connected to one side of the irregular block 38. On the other side of the irregular block 38, there is a fixed insertion block 39. By setting a connecting plate 33, a stable support is provided for the bolt 34 and the lifting block 31 with the surface thread of the bolt 34. By setting a rotating shaft 37, the irregular block 38 is positioned to move around the rotating shaft 37. By setting a linkage structure between the motor 32, the bolt 34 and the lifting block 31, when the motor 32 drives the bolt 34 to rotate, the lifting block 31 can move precisely along the axis of the bolt 34. In conjunction with the connecting block 35, the irregular block 38 is pushed to rotate around the rotating shaft 37, which drives the insertion block 39 to quickly adapt to the rectangular groove 24, greatly shortening the positioning and locking time when the mold 22 is changed.

[0026] In the above scheme, the bottom of the multi-station cold heading machine 1 is fixedly connected with a support leg 11, and the top of the multi-station cold heading machine 1 is fixedly connected with a support block 12. By setting the support leg 11 at the bottom of the multi-station cold heading machine 1, stable support is provided for the entire equipment, and the multi-station cold heading machine 1 is raised off the ground at a certain height to avoid the bottom of the equipment from directly contacting the damp environment of the ground and rusting. At the same time, it is convenient for operators to clean, inspect and maintain the equipment. By setting the support block 12 at the top of the multi-station cold heading machine 1, it serves as the installation carrier for auxiliary tooling during the cold heading process.

[0027] Example 1:

[0028] Please see Figure 2 - Figure 3 This utility model provides a technical solution: a circular groove 21 is provided inside the fixing block 2, and a circular ring 23 is slidably connected inside the circular groove 21. A mold 22 is sleeved inside the circular ring 23. By setting the sliding connection between the circular groove 21 and the circular ring 23, when it is necessary to change the mold 22 of different specifications, the circular ring 23 can be directly pulled out along with the mold 22 for overall replacement without reprocessing or adjusting the circular groove 21 of the fixing block 2, thus shortening the time for changing the mold 22, improving the equipment changeover efficiency, and adapting to the production needs of multiple varieties and small batches.

[0029] It should be added that a rectangular groove 24 is formed on the surface of the ring 23. The rectangular groove 24 is adapted to the insertion block 39. By setting the adaptation structure between the rectangular groove 24 on the surface of the ring 23 and the insertion block 39, when the insertion block 39 is embedded in the rectangular groove 24, the rotation and axial movement of the ring 23 in the groove 21 can be directly restricted, ensuring that the position of the mold 22 is fixed during cold heading, avoiding the displacement of the mold 22 due to equipment vibration, and ensuring the dimensional consistency of the cold-headed parts.

[0030] Example 2:

[0031] Please see Figure 4 - Figure 5 This utility model provides a technical solution: A groove 4 is formed inside the fixed block 2. A cylinder 41 is fixedly connected to the side wall of the groove 4. A piston rod is provided inside the cylinder 41. A moving block 42 is fixedly connected to the output end of the piston rod. A protrusion 43 is fixedly connected to the bottom of the moving block 42. A horizontal sliding groove 44 is formed inside the fixed block 2. A vertical sliding groove 45 is formed on the surface of the moving block 42. An upper slider 46 is slidably connected to the upper part of the vertical sliding groove 45, and a lower slider 47 is slidably connected to the lower part of the vertical sliding groove 45. A support is fixedly connected to the top of the moving block 42. A motor 49 is provided on one side of the support. The output end of the second machine 49 is equipped with a bidirectional lead screw 48. Through the cooperation of the cylinder 41 in the groove 4 and the moving block 42, the cylinder 41 drives the piston rod to move the moving block 42 smoothly along the horizontal slide groove 44. Combined with the cooperation of the protrusion 43 on the moving block 42 and the horizontal slide groove 44, it is ensured that the moving block 42 has no deviation in the horizontal direction. Through the drive combination of the second motor 49 and the bidirectional lead screw 48, when the second motor 49 drives the bidirectional lead screw 48 to rotate, it can drive the upper slider 46 and the lower slider 47 to move synchronously in opposite directions along the vertical slide groove 45, so as to realize the rapid clamping or release of the ring 23 and the internally sleeved mold 22.

[0032] Furthermore, an upper slider 46 is fitted on one side of the surface of the bidirectional lead screw 48, and a lower slider 47 is fitted on the other side of the surface of the bidirectional lead screw 48. By setting the upper slider 46 and the lower slider 47 on both sides of the surface of the bidirectional lead screw 48 respectively, when the motor 2 49 drives the bidirectional lead screw 48 to rotate, the upper slider 46 and the lower slider 47 can move in opposite directions or in the opposite direction along the vertical slide groove 45 at the same time, ensuring the synchronicity of the clamping action, avoiding the workpiece shifting due to uneven force caused by unilateral movement, and improving the workpiece positioning stability during cold heading.

[0033] Working principle: When changing mold 22, the ring 23 is slid into the circular groove 21 of the fixed block 2. Motor 1 32 drives the bolt 34 to rotate, and the lifting block 31 moves upward along the axis of the bolt 34, lifting the connecting block 35. This drives the irregular block 38 to rotate around the rotating shaft 37 on the support base 36, so that the insertion block 39 is embedded in the rectangular groove 24 on the surface of the ring 23, restricting the rotation and movement of the ring 23, and completing the positioning and locking of the mold 22. Then, the cylinder 41 is started, and the piston rod pushes the moving block 42 to move along the horizontal sliding groove 44. The protrusion 43 ensures that the moving block 42 is stable and without deviation until the moving block 42 moves to the position that matches the mold 22. Then, motor 2 49 is started, which drives the double-sided lead screw 48 to rotate. Because the threads on both sides of the double-sided lead screw 48 rotate in opposite directions, the upper slider 46 and the lower slider 47 move towards each other along the vertical sliding groove 45, clamping the ring 23 and the mold 22, further stabilizing the mold 22, and realizing the rapid positioning and locking of the mold.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
