[0002] A thread rolling device is a mechanical device used for surface processing of metal wires or bars. It mainly forms threads, teeth, or other specific patterns on the material surface through the relative movement of the thread rolling plate (die).

[0003] In existing traditional thread rolling devices, due to the lack of an effective limiting and pushing structure for the bolt blank, the blank is easily tilted by gravity or inertia during the transportation process, which leads to problems such as thread rolling misalignment and iron filings flying. This not only seriously reduces the processing accuracy, but also poses a threat to operational safety.

[0004] Therefore, the existing thread rolling machine's fixed processing device has a problem of missing limiting structure during the thread blank transportation process, which leads to misalignment and flying of iron filings. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6This utility model provides an embodiment of a thread rolling machine fixing processing device, including a base 1; it also includes a limiting push block 604 and a second limiting strip 2. A first connecting plate 101 is fixedly connected to the upper end of the base 1, and a second limiting strip 2 is fixedly connected to the upper end of the first connecting plate 101. A first clamping plate 201 is fixedly connected to the upper end of the second limiting strip 2, and a second clamping plate 203 is slidably disposed on the second limiting strip 2. The ends of the second clamping plate 203 and the first clamping plate 201 that are close to each other are used to place the bolt blank. Two sets of threaded sliding members are fixedly connected to the front end of the second clamping plate 203, and the threaded sliding members include a first limiting rod. 204, threaded post 205, and nut 206; four first limiting rods 204 and two nuts 206 are fixedly connected to the front end of the second clamping plate 203; two third limiting bars 202 are fixedly connected to the upper end of the second limiting bar 2; threaded sliding parts are installed on the third limiting bars 202; and threaded posts 205 are threadedly installed at both ends of the nuts 206 on the third limiting bars 202; a second connecting plate 102 is fixedly connected to the upper end of the base 1; the second connecting plate 102 is provided with a thread rolling gap adjustment component and a feeding component; a thread rolling linear reciprocating component is also provided at the upper end of the base 1; and the upper end of the first clamping plate 201 is rotatably set... A third synchronous pulley 6 and a fourth synchronous pulley 601 are provided.

A second transmission connecting belt 603 is sleeved on the outer wall of both the third synchronous pulley 6 and the fourth synchronous pulley 601. Evenly distributed limiting push blocks 604 are fixed to the outer wall of the second transmission connecting belt 603. Parts of the limiting push blocks 604 are located above the notch of the first clamping plate 201 and the second clamping plate 203. When the bolt blank is transferred from the feeding device to the gap between the first clamping plate 201 and the second clamping plate 203, it moves along the gap due to gravity. The material slides downwards at the angle of inclination at the gap into the limiting push block 604 on the second transmission connecting belt 603. Then, the third motor 602 is turned on, driving the third synchronous pulley 6 to rotate, thereby causing the second transmission connecting belt 603 to rotate and transport materials. The multiple limiting push blocks 604 on the second transmission connecting belt 603 clamp and carry the threaded blank at the gap for orderly feeding. During the feeding process, the limiting push blocks 604 provide forward thrust to the blank, which solves the problem that the bolt blank is skewed due to the lack of limiting and pushing clamping structure, causing misalignment of the thread rolling and splashing of iron filings.

The tooth rolling gap adjustment component includes a first fixing block 4 and a stationary tooth rolling block 404.

A first threaded sleeve 402 is fixedly connected to the inner wall of the second groove 401 on the first fixed block 4. The inner wall of the first threaded sleeve 402 and the outer wall of the threaded adjusting post 403 are threaded together. Next, two second threaded sleeves 407 are provided through the upper end of the stationary thread rolling block 404. Bolt fixing posts 408 are threaded on the second threaded sleeves 407. After passing through the second threaded sleeves 407 and the stationary thread rolling block 404, the bolt fixing posts 408 are threaded onto the limiting sleeves 406 in the third groove 405. By rotating the threaded adjusting post 403, the limiting sleeves 406 remain stationary, adjusting the movement between the stationary thread rolling block 404 and the sliding thread rolling block 303 to adapt to thread blanks of different sizes.

[0024] Please see Figure 3 In this embodiment, a second support base 105 and a first support base 104 are fixedly connected to the upper end of the base 1. A second synchronous pulley 107 is rotatably mounted on the first support base 104, and a first synchronous pulley 106 is rotatably mounted on the second support base 105. The first synchronous pulley 106 and the second synchronous pulley 107 are rotatably connected by a first transmission connecting belt 109. The rear end shaft of the second synchronous pulley 107 passes through the first support base 104 and is fixedly connected to a first motor 108. The first motor 108 drives the subsequent rotating wheel 3 to perform a limited linear reciprocating thread rolling operation.

[0025] Please see Figures 5-6In this embodiment, an L-shaped fixing block 501 is fixedly connected to the upper end of the second connecting plate 102. A push block 5 is slidably arranged on the left end and front end of the L-shaped fixing block 501. The push block 5 is L-shaped and a sliding column 502 is arranged on the push block 5. After the sliding column 502 passes through the L-shaped fixing block 501, a second fixing block 503 is fixedly connected. A spring 504 is fixedly connected to the front end of the second fixing block 503. The other end of the spring 504 is fixedly connected to the inner wall of the L-shaped fixing block 501. The spring 504 is located outside the sliding column 502. A second motor 505 is fixedly connected to the lower end of the L-shaped fixing block 501. After the output shaft of the second motor 505 passes through the L-shaped fixing block 501, a rotating plate 506 is fixedly connected. One end of the rotating plate 506 is in contact with the upper outer wall of the push block 5. The rotation of the rotating plate 506 and the reverse force of the spring 504 drive the push block 5 to slide, thereby performing the work of feeding the billet.

[0026] First, the output port of the feeding device and the first clamping plate 201 and the second clamping plate 203 on the second limiting strip 2 are connected and fixed. When the bolt blank is transferred from the feeding device to the gap between the first clamping plate 201 and the second clamping plate 203, it slides down along the inclined angle of the gap under the action of gravity into the limiting push block 604 on the second transmission connecting belt 603. Then, the third motor 602 is turned on and drives the third synchronous pulley 6 to rotate, so that the second transmission connecting belt 603 performs the work of rotating and conveying material. The multiple limiting push blocks 604 on the second transmission connecting belt 603 clamp the thread blank at the gap and perform orderly feeding. During the feeding process, the limiting push blocks 604 provide forward pushing force to the blank, which solves the problem of blank skewing caused by the lack of limiting and pushing clamping structure, resulting in misalignment of the thread rolling and iron filings flying. When the blank slides to the rear end of the push block 5, the second motor 505 is turned on and drives the rotating plate 506 to rotate. When the rotating plate 506 rotates, it provides forward pushing force to the blank. The push block 5 performs extrusion, then moves, and the rotating plate 506 stops extruding. The push block 5, under the reverse force of the spring 504, moves the blank carried on it backward, thus performing repeated pushing operations. Next, the first motor 108 is activated, driving the rotating wheel 3 to rotate via the transmission device. The sliding tooth-rolling block 303, limited by the first limiting strip 103, moves back and forth linearly, thus performing tooth-rolling operations on the blank between the sliding tooth-rolling block 303 and the stationary tooth-rolling block 404. The upper end of the tooth block 404 is provided with a baffle, and the lower end of the baffle and the upper end of the blank are in contact with each other to prevent the blank from moving upward during the tooth rolling operation. Before use, the position of the stationary tooth rolling block 404 on the second connecting plate 102 can be adjusted by rotating the two threaded adjusting columns 403. The gap between the second clamping plate 203 and the first clamping plate 201 can be adjusted by rotating the nuts 206 at both ends of the outer wall of the threaded column 205 on the third limiting bar 202, thereby adapting to different sized blanks for tooth rolling operation.
