Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, specifically to a thread rolling plate fixing device for thread rolling machines. Background Technology

[0002] Thread rolling machines are specialized equipment for producing screws. Thread rolling machines come in various specifications, such as automatic thread rolling machines, flatbed thread rolling machines, semi-automatic thread rolling machines, fully automatic thread rolling machines, and high-speed thread rolling machines. Thread rolling machines are lightweight, flexible, efficient, and possess advantages that other similar equipment cannot replace. Thread rolling machines avoid the limitations of lathes, drilling machines, or manual tapping, saving time and labor, reducing the risk of thread damage, and minimizing tap breakage. Thread rolling machines are suitable for all mechanical manufacturing industries, including machine tools, mold machinery, plastic machinery, printing machinery, packaging machinery manufacturers, construction machinery, automotive and motorcycle parts, aero-engines, locomotives and rolling stock, tobacco machinery, and general machinery industries.

[0003] The thread rolling plate and mounting base of a thread rolling machine are generally connected by screws. However, the two thread rolling plates need to maintain relative movement during operation. Insufficient rigidity of the screw connection may lead to misalignment between the plates, affecting the consistency of the thread pitch and causing cumulative errors. Moreover, the screw connection is prone to loosening under long-term vibration or high-load operation, resulting in gaps between the thread rolling plate and the equipment, which in turn causes thread profile deviation or dimensional errors during processing. In addition, when the thread rolling plate needs to be disassembled, all the screws must be unscrewed to complete the disassembly, which is very inconvenient. Furthermore, the frequent removal of screws during disassembly and assembly will gradually damage the microstructure of the thread surface, especially metal fatigue and stress concentration. Each time the threads are disassembled and assembled, the friction and extrusion between them will destroy the original fit accuracy, eventually causing the threads to fail to mesh effectively and affecting the normal use of the thread rolling machine. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a thread rolling plate fixing device for a thread rolling machine. It solves the technical problems in the prior art where the two thread rolling plates need to maintain relative movement during operation, and the insufficient rigidity of the screw connection may lead to misalignment between the plates, affecting the consistency of the thread pitch and causing cumulative errors. In addition, the screw connection is prone to loosening under long-term vibration or high-load operation, resulting in gaps between the thread rolling plate and the equipment, which in turn causes thread profile deviation or dimensional errors during processing. Furthermore, the disassembly and assembly of the screw connection is very inconvenient, and frequent disassembly of the screw will cause gradual damage to the microstructure of the thread surface, especially metal fatigue and stress concentration. Moreover, the friction and extrusion between the threads will destroy the original fit accuracy, ultimately causing the threads to fail to mesh effectively, affecting the normal use of the thread rolling machine.

[0024] like Figures 1-4 As shown, a wire rolling plate fixing device for a wire rolling machine according to an embodiment of the present invention is illustrated, including: a mounting base assembly 1, the mounting base assembly 1 including a mounting base body 101, the mounting base body 101 having limit protrusions 102 on both sides, the mounting base body 101 having two limit cavities 103 and a movable cavity 104 respectively inside, the mounting base body 101 having a first sliding groove 105 on both sides corresponding to the two limit cavities 103, the first sliding groove 105 communicating with the limit cavities 103, the mounting base body 101 having a second sliding groove 106 on both sides corresponding to the movable cavity 104, the second sliding groove 106 communicating with the movable cavity 104, and the mounting base body 101 having an insertion groove 107 on both sides; The thread rolling plate assembly 3 is disposed on the top of the mounting base body 101. The thread rolling plate assembly 3 includes a thread rolling plate body 301 located on the top of the mounting base body 101. A limiting groove 302 is formed inside the thread rolling plate body 301, and the limiting groove 302 and the limiting protrusion 102 are inserted into each other. The bottom of the thread rolling plate body 301 has a through hole 303, the inside of the thread rolling plate body 301 has a slot 305 corresponding to the position of the through hole 303, and the inside of the thread rolling plate body 301 has a connecting groove 304. Limiting component 2 is disposed within the limiting cavity 103; The limiting component 2 includes a first spring 201 disposed in the limiting cavity 103. One end of the first spring 201 is fixedly connected to the inner wall of the limiting cavity 103, and the other end of the first spring 201 is fixedly connected to a moving plate 202. A first damping rod is disposed inside the first spring 201. The movable plate 202 slides within the limiting cavity 103. A first lever 204 is fixedly connected to the side of the movable plate 202. The first lever 204 slides within the first sliding groove 105. A plug-in post 203 is fixedly connected to the top of the movable plate 202. The plug-in post 203 passes through the through hole 303 and the limiting protrusion 102 in sequence and is plugged into the slot 305.

[0025] In this embodiment, during installation, the limiting protrusion 102 and the limiting groove 302 fit together. The concave-convex structure of the limiting protrusion 102 and the limiting groove 302 increases the contact area between the mounting base body 101 and the thread rolling plate body 301. The concave-convex interlocking achieves a stable connection between the mounting base body 101 and the thread rolling plate body 301. Under the support of the first spring 201, the moving plate 202 drives the insertion post 203 to move upward. The insertion post 203 passes through the through hole 303, the limiting protrusion 102 and the slot 305 in sequence to achieve a stable connection between the mounting base body 101 and the thread rolling plate body 301, improves the stability of the connection part, prevents the thread rolling plate body 301 from shaking during the thread rolling process, reduces abnormal wear and the frequency of machine downtime and replacement, and ensures the stable operation of the thread rolling process.

[0026] like Figures 2-6 As shown, it illustrates a reinforcing component 4 in another embodiment of the present invention. The reinforcing component 4 is provided in the first sliding groove 105. The reinforcing component 4 includes a second spring 401 provided inside the first sliding groove 105. One end of the second spring 401 is fixedly connected to the inner wall of the first sliding groove 105, and the other end of the second spring 401 is fixedly connected to a movable plate 402. A second damping rod is provided inside the second spring 401. The movable plate 402 slides within the movable cavity 104. A rigid protrusion 403 is fixedly connected to the top of the movable plate 402. The top of the rigid protrusion 403 penetrates the mounting base body 101 and is inserted into the connecting groove 304. The movable plate 402 is fixedly connected to both sides of the second lever 404. The second lever 404 slides in the second sliding groove 106. The second lever 404 is provided with a limit connection part 405 on both sides. A rod 406 is inserted into the side of the limiting connection part 405, and the rod 406 is inserted into the insertion slot 107.

[0027] In this embodiment, after the mounting base body 101 and the thread rolling plate body 301 are connected, under the action of the second spring 401, the movable plate 402 drives the rigid protrusion 403 to move upward, so that the top of the rigid protrusion 403 is inserted into the connecting groove 304. Then, the insertion rod 406 is inserted into the insertion groove 107 to limit the position of the second lever 404 and the rigid protrusion 403. The rigid protrusion 403 increases the actual contact area between the connecting surfaces, reduces local stress concentration, and avoids stress concentration in weak areas. The tapered shape of the protrusion 403 is geometrically constrained to limit the relative movement between the mounting base body 101 and the thread rolling plate body 301, preventing misalignment between plates due to insufficient rigidity of the connection part, which would affect the consistency of the thread pitch and cause cumulative errors. The insertion slots 107 are set in two sets. The upper set of insertion slots 107 is used to increase the connection stability when reinforcement is carried out after installation, while the lower set of insertion slots 107 is used to limit the retracted rigid protrusion 403 during disassembly, making it easier to disassemble.
