Description

Technical Field

[0001] This utility model relates to the field of forging press technology, specifically to a clamping mechanism for a CNC radial forging press. Background Technology

[0002] Radial forging is a rotary forging method specifically designed for processing solid or hollow long shaft parts. CNC radial forging presses can process metal billets of various materials and shapes. Through plastic deformation during forging, the grains within the material are refined, and the flow lines are more rationally distributed, significantly enhancing the strength, toughness, and other properties of the metal billet to meet the requirements of practical applications. In the processing of forgings using CNC radial forging presses, the forgings need to be positioned. In industrial production, many mechanical parts, such as bearing rings and gear blanks, are based on cylindrical or annular shapes and require forging to improve material properties and internal structure.

[0003] When radially forging cylindrical metal billets, traditional clamping mechanisms struggle to achieve concentric positioning. When there is a significant deviation between the central axis of the cylindrical forging and the machining axis of the forging press, the roundness of the forged cylindrical workpiece will be poor, affecting its subsequent performance.

[0004] Therefore, this utility model proposes a clamping mechanism for a CNC radial forging press to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamping mechanism for a CNC radial forging press, which solves the problem in the prior art that it is impossible to achieve rapid concentric positioning of cylindrical forgings, thus affecting the performance of the forged workpiece.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A clamping mechanism for a CNC radial forging press includes a machine body, a base mounted on the machine body, a positioning component mounted on the base, and a mounting groove corresponding to the positioning component on the base. The positioning component includes a centering component and a clamping component. The centering component includes a mounting seat, which is installed in the middle of the base. A positioning hole is provided on the top of the base corresponding to the mounting seat. A through hole is provided on the mounting seat along the axial direction. A tapered shaft slides up and down within the through hole. A lead screw is threaded to the middle of the tapered shaft. The lead screw is rotatably connected to the mounting seat. A drive motor is connected to the lower end of the mounting seat. The output shaft of the drive motor is connected to the lead screw. A sleeve is provided between the tapered shaft and the through hole, and the sleeve has multiple openings evenly spaced radially. The clamping assembly includes a gripper and a moving mechanism. The gripper is symmetrically arranged along the sleeve. The moving mechanism includes a rotating plate rotatably connected to the mounting groove. A sliding block is connected to the lower end of the gripper. A sliding groove is provided on the base corresponding to the sliding block. A connecting rod is connected between the sliding block and the rotating plate. The connecting rod is rotatably connected to both the sliding block and the rotating plate. A driving cylinder is connected in the mounting groove. The driving cylinder is arranged parallel to the sliding groove. The driving shaft of the driving cylinder is connected to the sliding block.

[0008] By adopting the above technical solution, the forging can be centered, and the clamps can hold the forging tightly to prevent displacement of the forging during the forging process.

[0009] Furthermore, the gripper is detachably connected to the sliding block.

[0010] By adopting the above technical solution, the grippers can be changed quickly, ensuring the continuity of production.

[0011] Furthermore, the inner surface of the gripper is connected to a clamping surface, and the clamping surface is provided with anti-slip texture.

[0012] By adopting the above technical solution, the friction force can be effectively increased, preventing displacement of the forgings during the forging process and ensuring the smooth progress of the forging work.

[0013] Furthermore, an annular groove is provided on the inner side of the top of the expansion sleeve, and the upper end of the lead screw is rotatably connected to the annular groove.

[0014] By adopting the above technical solution, the stability of the connection between the lead screw and the expansion sleeve can be guaranteed, so that the expansion sleeve can expand outward evenly.

[0015] Furthermore, the base is connected to a side plate corresponding to the mounting groove, and the side plate is detachably connected to the base.

[0016] By adopting the above technical solutions, maintenance and repair are facilitated, maintenance time is shortened, and equipment utilization is improved.

[0017] Furthermore, a connecting block is connected to the bottom of the mounting base, and a screw is threadedly connected to the connecting block along the longitudinal direction. A bevel gear assembly is connected to the bottom of the screw, and the bevel gear assembly is driven by a drive shaft, which is rotatably connected to the mounting base.

[0018] By adopting the above technical solution, the height of the centering component can be initially adjusted, thereby adapting to cylindrical / ring-shaped forgings of different lengths.

[0019] Furthermore, a rotating handwheel is connected to the end of the drive shaft.

[0020] By adopting the above technical solution, manual operation is facilitated.

[0021] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention places the forging on a base, starts the drive motor, and causes the expansion sleeve to expand outward evenly, thereby achieving the centering operation of the forging and adjusting its central axis to coincide with the processing axis of the forging press. After centering is completed, the grippers are symmetrically arranged along the expansion sleeve, and then the grippers tightly clamp the forging, which can prevent the forging from shifting during the forging process and ensure the smooth progress of the forging work.

[0032] The positioning assembly includes a centering assembly and a clamping assembly. The centering assembly includes a mounting base 105, which is installed in the middle of the base 2. A positioning hole 6 is provided on the top of the base 2 corresponding to the mounting base 105. A through hole 7 is provided on the mounting base 105 along the axial direction. A tapered shaft 8 slides up and down in the through hole 7. A lead screw 9 is threadedly connected to the middle of the tapered shaft 8. The lead screw 9 is rotatably connected to the mounting base 105. A drive motor 11 is connected to the lower end of the mounting base 105. The output shaft of the drive motor 11 is connected to the lead screw 9. An expansion sleeve 12 is provided between the tapered shaft 8 and the through hole 7. The expansion sleeve 12 has multiple openings 13 evenly provided in the radial direction. An annular groove 14 is provided on the inner side of the top of the expansion sleeve 12. The upper end of the lead screw 9 is rotatably connected to the annular groove 14.

[0033] A connecting block 15 is connected to the bottom of the mounting base 105. A screw 16 is threadedly connected to the connecting block 15 along the longitudinal direction. A bevel gear assembly 17 is connected to the bottom of the screw 16. The bevel gear assembly 17 is driven by a drive shaft 18, which is rotatably connected to the mounting base 105. A handwheel 19 is connected to the end of the drive shaft 18.

[0034] The clamping assembly includes grippers 20 and a moving mechanism. The grippers 20 are symmetrically arranged along the expansion sleeve 12 and are detachably connected to the sliding block 24. The inner surface of the grippers 20 is connected to a clamping surface 21, on which anti-slip textures 22 are formed. The moving mechanism includes a rotating plate 23, which is rotatably connected in the mounting groove 3. The lower end of the grippers 20 is connected to the sliding block 24. The base 2 has a sliding groove 25 corresponding to the sliding block 24. A connecting rod 26 is connected between the sliding block 24 and the rotating plate 23. The connecting rod 26 is rotatably connected to both the sliding block 24 and the rotating plate 23. A drive cylinder 27 is connected in the mounting groove 3. The drive cylinder 27 is arranged parallel to the sliding groove 25, and the drive shaft 18 of the drive cylinder 27 is connected to the sliding block 24.

[0035] The working process of this utility model is as follows:

[0036] First, the mechanism is adjusted according to the forging to be processed. First, turn the handwheel 19, and the drive shaft 18 will rotate accordingly, driving the bevel gear assembly 17 to rotate, which in turn causes the screw 16 to move up and down in the connecting block 15. Then, the up and down movement of the screw 16 drives the mounting base 105 to move axially, thereby making a preliminary adjustment to the height of the centering assembly, and thus adapting to cylindrical / ring-shaped forgings of different lengths.

[0037] The forging is then placed on the base 2, and the drive motor 11 is started. The output shaft of the drive motor 11 drives the lead screw 9 to rotate. Since the lead screw 9 and the tapered shaft 8 are threadedly connected, and the lead screw 9 is rotatably connected to the mounting base 105, the rotation of the lead screw 9 causes the tapered shaft 8 to slide up and down in the through hole 7. As the tapered shaft 8 moves upward, it gradually expands the expansion sleeve 12, which then expands outward under the action of the tapered shaft 8. At the same time, the upper end of the lead screw 9 rotates in the annular groove 14, ensuring the stability of the connection between the lead screw 9 and the expansion sleeve 12, so that the expansion sleeve 12 can expand outward evenly, thereby achieving the centering operation of the forging and adjusting its central axis to coincide with the processing axis of the forging press.

[0038] After centering is completed, the drive cylinder 27 is activated. The drive shaft 18 of the drive cylinder 27 pushes the connected sliding block 24 to slide within the sliding groove 25, thereby driving the connecting rod 26 to move, which in turn causes the rotating plate 23 to rotate. The rotation of the rotating plate 23, in turn, drives the sliding blocks 24 at the lower ends of the other grippers 20 to move synchronously through the connecting rod 26, realizing the opposite movement of the grippers 20. The grippers 20 are symmetrically arranged along the expansion sleeve 12, thus tightly clamping the forging. The clamping surface 21 on the inner surface of the grippers 20 is provided with anti-slip texture 22, which can effectively increase friction and prevent displacement of the forging during the forging process, ensuring the smooth progress of the forging work. During operation, the positioning can be finely adjusted by the drive motor 11 and the drive cylinder 27.
