Description

Technical Field

[0001] The present invention relates to the technical field of screw thread rolling, and particularly to a high-precision thread rolling machine for screw processing. Background Technique

[0002] In modern industrial production, screws, as fundamental and crucial connecting components, their processing quality directly affects the performance and safety of various products. With the rapid development of the manufacturing industry and the continuous increase in the requirements for product precision, more stringent challenges are posed to the precision and efficiency of screw processing equipment. When traditional thread rolling machines are used for screw processing, they often face many problems, resulting in screws processed being difficult to meet the growing high-precision requirements.

[0003] Early thread rolling machines had limitations in structural design, and there was a lack of precise and effective control in the feeding process. The feeding mechanism could not ensure the stable and accurate delivery of screws to the thread rolling station, resulting in a significant reduction in the consistency and precision of thread rolling processing. Moreover, the working mode of the thread rolling module was relatively single, making it difficult to flexibly and efficiently process screws of different specifications and materials, and it was difficult to guarantee the processing precision. At the same time, a large amount of cutting fluid generated during the processing, if not properly handled, would not only cause waste of resources but also pollute the environment. Traditional equipment had limited means for the recycling of cutting fluid, often directly discharging a large amount of cutting fluid containing impurities, increasing production costs and also going against the concept of green production.

[0004] In addition, for the processing of screws after thread rolling, the previous methods were also relatively simple and rough. Usually, only simple cleaning was carried out, which could not effectively remove the residual cutting fluid and impurities on the screw surface, affecting the appearance quality and subsequent use performance of the screws. Moreover, the degree of automation of the entire processing process was low, requiring a large amount of manual operation, which not only increased the labor intensity but also easily led to unstable processing quality due to human factors, and it was also difficult to improve the production efficiency.

[0005] Therefore, we propose a high-precision thread rolling machine for screw processing to solve the problems raised above. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0030] Please refer to Figures 1-8 , the present invention provides a technical solution: a high-precision thread rolling machine for screw processing, including a frame 1. A vibrating bowl 2 is installed on the front side of the upper end of the frame 1. A carrier 3 is installed on the upper side of the rear end of the frame 1. A conveyor belt assembly 4 is installed on the front side of the carrier 3, and a feeding mechanism 5 is installed on the rear side of the carrier 3; The feeding mechanism 5 includes a sliding table cylinder 51 and a first electric push rod 53 installed on the carrier 3. A pushing plate 52 is installed at the output end of the sliding table cylinder 51. A pushing rod 54 is installed at the output end of the first electric push rod 53. The feeding mechanism 5 further includes a material groove 55 opened at the upper end of the carrier 3. The sliding table cylinder 51 pushes the screws on the conveyor belt assembly 4 to the front end of the material groove 55 through the pushing plate 52. The first electric push rod 53 pushes the screws from the front end of the material groove 55 to the rear end of the material groove 55 through the pushing rod 54; The thread rolling module 7 includes two hydraulic cylinders 71. The two hydraulic cylinders 71 are respectively fixed on the left and right sides of the mounting frame 6. The output end of the hydraulic cylinder 71 is connected to a movable frame 72. A thread rolling assembly 73 is installed on the movable frame 72. The two thread rolling assemblies 73 are symmetrically distributed about the center of the material groove 55 left and right; The vibrating bowl 2 works to convey screws one by one to the conveyor belt assembly 4. The conveyor belt assembly 4 sends the screws to the pushing plate 52. Then the sliding table cylinder 51 works, and its output end pushes the pushing plate 52 to move, pushing the screws on the conveyor belt assembly 4 to the front end of the material groove 55. Then the first electric push rod 53 acts, and the pushing rod 54 at its output end pushes the screws located at the front end of the material groove 55 to the middle of the two thread rolling assemblies 73. Since the two thread rolling assemblies 73 are symmetrically distributed about the center of the material groove 55 left and right, under the drive of the hydraulic cylinder 71, the two thread rolling assemblies 73 can perform thread rolling processing on the screws located in the material groove 55, and process threads on the screw surface through actions such as rotation and extrusion; At the upper rear side of the frame 1, a mounting bracket 6 is fixedly installed. A rolling thread module 7 is installed on the mounting bracket 6, and a cutting fluid supply component 8 is installed on the mounting bracket 6. Moreover, a filtering and guiding member 9 is installed at the rear side of the frame 1. An centrifugal filtering component 11 is installed on the side of the filtering and guiding member 9 through a control member 10. The centrifugal filtering component 11 is used for recycling the cutting fluid; The filtering and guiding member 9 includes a guiding pipe 91 fixed on the frame 1. An inlet 92 is opened at the upper end of the guiding pipe 91. A filter plate 93 is installed in the middle of the guiding pipe 91. And a screw outlet 94 is opened at the lower front side of the guiding pipe 91; A liquid guiding plate 95 is installed below the filter plate 93 at the rear side of the guiding pipe 91. A liquid guiding pipe 96 is fixed at the rear end of the guiding pipe 91. And an inlet 97 is opened above the liquid guiding pipe 96. The cutting fluid solution filtered by the filter plate 93 enters the liquid guiding pipe 96 from the liquid guiding plate 95 and the inlet 97 in sequence; The centrifugal filtering component 11 includes an outer cylinder 111. A top cover 112 is fitted and installed at the upper end of the outer cylinder 111. And a plurality of pressing rods 113 are installed equiangularly below the top cover 112. A fixing ring 115 is fixedly installed inside the upper end of the outer cylinder 111. A filter cartridge member 114 is placed on the fixing ring 115. A driving block 116 is installed at the bottom of the outer cylinder 111. The driving block 116 is used to drive the filter cartridge member 114 to rotate for centrifugally filtering the cutting fluid. A discharge pipe 117 is installed at the lower end of the outer cylinder 111. And the upper end of the discharge pipe 117 is connected to the feed end of the cutting fluid supply component 8 through a flange; The filter cartridge member 114 includes a filter cylinder body 1141, a receiving ring 1142 and a connecting block 1143. The receiving ring 1142 is fixed on the outer side of the upper end of the filter cylinder body 1141. And the connecting block 1143 is fixedly installed on the outer side of the lower end of the filter cylinder body 1141; A first ball 1131 is movably installed inside the lower end of the pressing rod 113. And a second ball 1151 is movably installed inside the upper end of the fixing ring 115. The pressing rod 113 and the fixing ring 115 are respectively attached to the upper and lower surfaces of the receiving ring 1142 through the first ball 1131 and the second ball 1151; A connecting groove 11431 matching with the driving block 116 is opened inside the lower end of the connecting block 1143. The connecting groove 11431 is designed in a "cross" structure; The control member 10 includes a second electric push rod 101, a guiding rod 102 and a fixing sleeve 103. The second electric push rod 101 is fixed on the side of the guiding pipe 91. The output end of the second electric push rod 101 is connected to the outer cylinder 111. And the ends of the guiding rod 102 and the fixing sleeve 103 are respectively fixed on the guiding pipe 91 and the outer cylinder 111. And the guiding rod 102 slides inside the fixing sleeve 103; The materials after thread rolling processing include screws and a cutting fluid solution, which enter the guiding pipe 91 from the inlet 92. The materials move downward in the guiding pipe 91. When passing through the filter plate 93, the cutting fluid solution passes through the filter plate 93, while the screws are intercepted above the filter plate 93. The filtered cutting fluid solution is guided by the liquid guiding plate 95 at the rear side of the guiding pipe 91 and enters the liquid guiding pipe 96 from the inlet 97, realizing the preliminary separation of the cutting fluid solution and the screws; The cutting fluid solution containing impurities enters the filter cartridge 114 in the outer cylinder 111 through the liquid guide pipe 96. The external motor drives the driving block 116 to rotate. Since the connection groove 11431 inside the lower end of the connecting block 1143 is in a "cross" structure and is matched with the driving block 116, the driving block 116 can drive the filter cartridge 114 to rotate. During the rotation, due to the action of centrifugal force, the impurities in the cutting fluid are thrown towards the inner wall of the filter cylinder body 1141, while the relatively pure cutting fluid passes through the filter screen of the filter cylinder body 1141 and enters the inside of the outer cylinder 111, and then is conveyed to the feeding end of the cutting fluid supply assembly 8 through the discharge pipe 117, realizing the recycling of the cutting fluid. Subsequently, when the filter cartridge 114 needs to be cleaned, the discharge pipe 117 and the cutting fluid supply assembly 8 are separated, and the electric push rod two 101 is started to drive the centrifugal filtration assembly 11 to move. Under the action of the relative position, the liquid guide pipe 96 is separated from the inside of the centrifugal filtration assembly 11. Subsequently, the top cover 112 and the filter cartridge 114 are removed in sequence, so that the impurities inside the filter cartridge 114 can be cleaned; A processing box 12 is placed on the lower side of the rear end of the frame 1. The processing box 12 is used for processing the rolled screws. A shaking member 13 is installed inside the processing box 12; the shaking member 13 includes a limiting rod 131 fixed inside the processing box 12. A filter screen plate 132 is slidably installed up and down on the limiting rod 131. A pressure spring 133 is sleeved on the limiting rod 131, and both ends of the pressure spring 133 are connected to the limiting rod 131 and the filter screen plate 132 respectively; two rotating rods 134 are arranged below the filter screen plate 132, and both rotating rods 134 are installed on the processing box 12 by bearings, and cams 135 are fixed on the rotating rods 134, and transmission belt assemblies 136 are installed on the outer sides of the ends of the two rotating rods 134 of the processing box 12; a water inlet pipe 121 and a drain pipe 122 are connected and installed on the processing box 12. The water inlet pipe 121 and the drain pipe 122 are respectively located on the upper and lower sides of the filter screen plate 132, and a mounting plate 123 is detachably installed above the processing box 12, and a blower 124 is installed on the mounting plate 123; The screws after thread rolling processing enter the processing box 12 from the screw discharge port 94 and fall on the filter screen plate 132. The two rotating rods 134 rotate synchronously through the transmission belt assembly 136, and the cams 135 on the rotating rods 134 also rotate accordingly. The cams 135 contact the filter screen plate 132 and push the filter screen plate 132 to slide up and down on the limiting rod 131. At the same time, the pressure spring 133 plays a role in buffering and resetting, causing the filter screen plate 132 to shake, so that the screws move on the filter screen, facilitating the cleaning and other processing of the screws. The water inlet pipe 121 injects cleaning water into the processing box 12 to clean the screws. The sewage after cleaning is discharged through the drain pipe 122. After the cleaning is completed, the blower 124 on the mounting plate 123 works to dry the screws in the processing box 12.

[0031] Working principle: When using this high-precision thread rolling machine for screw processing, as Figures 1-8 shown, first, the screws to be processed are put into the vibrating bowl 2. Start the vibrating bowl 2 to orderly convey the screws one by one. Utilize the cooperation of the feeding mechanism 5 and the thread rolling module 7 to perform thread rolling operations on the screws. Then, they enter the filtering and guiding part 9 to separate the screws from the cutting fluid. The cutting fluid is centrifugally filtered through the centrifugal filtering component 11. Subsequently, the cutting fluid supply component 8 recycles the filtered cutting fluid through the pump body and the discharge pipe 117. The processed screws enter the treatment box 12 from the screw discharge port 94 and then fall on the filter screen plate 132. By setting the water inlet pipe 121, the drain pipe 122, and the blower 124, the cleaning and drying of the screws are realized, ensuring the cleanliness of the screw surface and improving the product quality. At the same time, the entire treatment process has a high degree of automation, reducing manual operations and improving production efficiency.
