[0002] In modern industrial production, bolts are widely used standard parts with huge demand and high requirements for product quality and production efficiency. Thread rolling is a key step in bolt processing, mainly used to process threads that meet specifications on the surface of bolt blanks.

[0003] Traditional automated thread rolling equipment typically has a fixed die movement stroke, which makes it difficult to meet the processing requirements of bolts of different specifications. When it is necessary to process bolts of different lengths and thread specifications, it is often necessary to replace the entire set of dies or perform complex debugging on the equipment, which is time-consuming and labor-intensive. The equipment has poor versatility and production flexibility.

[0004] In view of this, we propose a thread rolling mechanism for bolt processing. Utility Model Content

[0017] Compared with the prior art, this utility model provides a thread rolling mechanism for bolt processing, which has the following beneficial effects:

[0018] 1. The thread rolling mechanism for bolt processing, in order to achieve efficient thread rolling of bolts, is designed with a processing mechanism that works in conjunction with an asynchronous motor to drive a rotating disc. The auxiliary slide rail and auxiliary slider on the disc drive a cylindrical block to perform circumferential motion. The cylindrical block pushes a moving block along the first slide rail to perform reciprocating linear motion through a connecting rod, so that the moving mold cooperates with the fixed mold, thereby achieving the purpose of thread rolling of the bolt. Based on this, by adjusting the position of the cylindrical block on the disc, the eccentricity of the block relative to the center of the disc is changed, thereby achieving flexible adjustment of the reciprocating linear motion distance of the moving mold to meet the thread rolling requirements of bolts of different specifications.

[0019] 2. The thread rolling mechanism for bolt processing, in order to improve the quality and efficiency of bolt thread rolling, is equipped with an auxiliary mechanism that works with a water pump to draw coolant from the water tank and spray it onto the processing area through a curved pipe and a flat nozzle. The coolant cools and lubricates the processing area while carrying away the debris generated during processing. The coolant flows back to the water tank through the drain hole and is filtered through a coarse filter plate and a dense filter plate, thereby achieving the purpose of recycling the coolant and improving processing quality and efficiency.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A thread rolling mechanism for bolt processing includes a base 1, a bracket 2 fixedly installed on the top of the base 1, a material conveying assembly 3 fixedly installed on the top of the bracket 2, and a drainage hole opened at the center of the top of the bracket 2.

[0033] In one embodiment of this utility model, a processing mechanism 4 is fixedly installed on the top of the bracket 2. The processing mechanism 4 includes a fixed mold 41. The fixed mold 41 is fixedly installed at one end of the top of the bracket 2, and a first slide rail 42 is fixedly installed at the other end of the top of the bracket 2. A first slider 43 is slidably installed inside the first slide rail 42. The first slide rail 42 and the first slider 43 are matched in size. A moving block 44 is fixedly installed on the side wall of the first slider 43. A moving mold 45 is fixedly installed on the side wall of the moving block 44. The fixed mold 41 is threaded on the surface of the moving mold 45. An asynchronous motor 46 is fixedly installed on the side wall of the base 1. The output end of the asynchronous motor 46 is fixedly installed at the center inside the disc 47. The side wall of the disc 47 is fixedly installed inside the disc 47. An auxiliary slide rail 48 is fixedly installed, and an auxiliary slider 49 is slidably installed inside the auxiliary slide rail 48. One end of a cylindrical block 410 is fixedly installed on the side wall of the auxiliary slider 49, and the other end of the cylindrical block 410 is rotatably installed inside the side wall of the moving block 44 via a connecting rod 411. A U-shaped plate 412 is fixedly installed on the side wall of the auxiliary slide rail 48, and a motor 413 is fixedly installed on the inner wall of the U-shaped plate 412. A second threaded rod 414 is fixedly installed at the output end of the motor 413. The outer walls of both ends of the second threaded rod 414 are rotatably installed inside the auxiliary slide rail 48 via bearing components. The outer wall of the second threaded rod 414 is threadedly fitted inside the auxiliary slider 49, and the diameter of the second threaded rod 414 is adapted to the threaded hole inside the auxiliary slider 49.

[0034] In this embodiment, while the processing mechanism 4 is running, the water pump 51 is started. The water pump 51 generates suction, drawing coolant from the bottom side wall of the water tank 55 fixedly installed on the top of the base 1 through the hose 54. The coolant flows into the bend 52 through the outlet of the water pump 51, and then is evenly sprayed onto the processing areas of the fixed mold 41 and the moving mold 45 through the flat nozzle 53 at the other end of the bend 52. The coolant reduces the high temperature generated by the friction between the mold and the bolt, preventing the mold from deforming or aggravating wear due to overheating. On the other hand, it forms a lubricating film on the surface of the mold and the bolt, reducing friction and improving the processing accuracy and smoothness of the bolt threads. During the processing, metal debris is carried by the flowing coolant and flows back to the water tank 55 through the drain hole at the top center of the support 2. In the water tank 55, the coolant first passes through the upper coarse filter plate 56, where the larger pores of the coarse filter plate 56 intercept and filter out larger debris particles. Then, the coolant continues to flow downwards and passes through the lower dense filter plate 57, where the smaller pores of the dense filter plate 57 perform fine filtration of the coolant, further removing tiny particulate impurities and purifying the coolant. This achieves the recycling of the coolant and continuously provides cooling and lubrication support for the processing.

[0035] In one embodiment of this utility model, an auxiliary mechanism 5 is provided on the first slide rail 42. The auxiliary mechanism 5 includes a water pump 51. The water pump 51 is fixedly installed at the top of the first slide rail 42. The water outlet end of the water pump 51 is fixedly installed at one end of the bend pipe 52. The other end of the bend pipe 52 is fixedly installed with a flat nozzle 53. The water inlet end of the water pump 51 is fixedly installed with a hose 54. The other end of the hose 54 is fixedly installed on the bottom side wall of the water storage tank 55. The water storage tank 55 is fixedly installed on the top of the base 1. A coarse filter plate 56 and a dense filter plate 57 are snapped together inside the water storage tank 55. The diameter of the small hole on the coarse filter plate 56 is larger than the diameter of the small hole on the dense filter plate 57. The coarse filter plate 56 is located above the dense filter plate 57.

[0036] In this embodiment, according to the specifications of the bolt to be processed, the motor 413 on the inner wall of the U-shaped plate 412 is controlled to rotate the second threaded rod 414. Since the second threaded rod 414 is threadedly engaged with the auxiliary slider 49, the auxiliary slider 49 moves within the auxiliary slide rail 48, causing the cylindrical block 410 to change its position on the disc 47. After adjusting the appropriate reciprocating linear motion distance of the moving mold 45, the feeding assembly 3 starts working, accurately conveying the bolt to be processed to the processing area between the fixed mold 41 and the moving mold 45 according to a predetermined path and speed, completing the bolt feeding process. Waiting for the thread rolling process, the asynchronous motor 46 is started, and its output end drives the disc 47 to start rotating. As the disc 47 rotates, the auxiliary slider installed in the auxiliary slide rail 48 inside the side wall of the disc 47 moves. 49. Driven by the disc 47, the cylindrical block 410 fixed to the side wall of the auxiliary slider 49 moves in a circular motion. The cylindrical block 410 is rotatably connected to the moving block 44 through the connecting rod 411. Due to the transmission of the connecting rod 411, the circular motion of the cylindrical block 410 is converted into the reciprocating linear motion of the moving block 44 along the first slide rail 42. The moving mold 45 fixed to the side wall of the moving block 44, under the sliding cooperation of the first slider 43 and the first slide rail 42, moves closer and further away from the fixed mold 41 as the moving block 44 makes a stable reciprocating linear motion. Using the threads set on the surfaces of the fixed mold 41 and the moving mold 45, the bolt surface in the middle position is squeezed and cut during the relative motion of the two, and the required threads are gradually processed.
