Description

Technical Field

[0001] The invention specifically relates to the technical field of high-strength bolt steel processing, and in particular to a high-strength bolt steel segment processing device. Background Art

[0002] High-strength bolt steel is a steel material used to manufacture high-strength bolts. In modern industrial production, high-strength bolts are widely used in various mechanical equipment, bridges, buildings and other fields. Their quality and performance are directly related to the safety and reliability of the entire structure. The processing quality of high-strength bolt steel sections is crucial to the performance of the bolts. When threading the steel sections, the existing processing equipment may not be able to accurately control the pitch and tooth shape of the threads, resulting in unstable thread quality, affecting the matching accuracy of the bolts and nuts, and thus reducing the connection strength of the bolts. In addition, the traditional processing equipment has a low degree of automation and requires a lot of manual operation, which is not only labor-intensive, but also prone to human errors, making it difficult to meet large-scale, high-quality production needs.

[0003] At present, when traditional high-strength bolts are rolled, since the bolts have nuts, the bolts cannot be effectively transferred through two rolling wheels during thread rolling. Therefore, the processing position of the bolts needs to be placed manually. The manual placement makes the work efficiency low during the bolt processing, and the traditional thread rolling assembly can only adjust the position of one of the rollers when processing bolts of different sizes. In this way, the center line between the two rollers may be offset during thread rolling, so when the bolts are rolled, the thread teeth will be incomplete, resulting in waste. Summary of the invention

[0004] The object of the present invention is to provide a high-strength bolt steel section processing device. In this structure, two groups of first gears and second gears are arranged on one side of the mounting shell, and the two second gears are meshed by matching gears. In this way, when adjusting the two thread rolling wheels, the two thread rolling wheels can be effectively guaranteed to rotate synchronously. The two thread rolling wheels can be adjusted inward or outward at the same time by an electric push cylinder, which effectively meets the effect of processing bolts of different sizes. In feeding the bolts, the downward pressure structure is alternately realized by two cam plates to drive the feeding clamp to move and flip, thereby realizing the effect of continuous automatic feeding, thereby improving work efficiency, so as to solve the problems of the above-mentioned background technology.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, when in use, the transmission and feeding of the screw to be processed is realized by the vibration plate, and the steering structure at the end of the cross bar is realized by the left and right movement of the mobile frame to realize the flipping of the direction of the first feeding clamp and the second feeding clamp in the cooperation of the pressing structure. In the process of the left and right movement of the mobile frame, the gear plate cooperates with the third gear to realize the rotation and alternating feeding of the first feeding clamp and the second feeding clamp on the top of the rotating plate, thereby effectively improving the feeding efficiency;

[0017] 2. In the present invention, in the feeding, the reducer drives the screw to rotate, and the screw realizes the left and right movement of the moving frame and the crossbar. During the movement, the second drive motor drives the rotating shaft to rotate through the connecting belt, and the cam plates at both ends of the rotating shaft rotate. The two cam plates are arranged at 90 degrees. In this way, when the cam plates rotate, the cam plates can be effectively alternately realized to realize the downward pressing structure driving the steering structure to realize the adjustment of the feeding clamp position;

[0018] 3. In the present invention, when the moving frame moves to one side of the vibration plate, the first feeding clamp and the second feeding clamp move synchronously, and the third gear and the toothed plate connected to the moving frame are meshed at this time, so that the first feeding clamp close to the side of the vibration plate rotates through the rotation of the rotating shaft. At this time, the first feeding clamp moves to the position of the second feeding clamp, and the second feeding clamp moves to one side of the supporting shaft. At this time, the first feeding clamp places the bolt in the first feeding clamp. After the loading is completed, the moving frame moves to the right under the action of the screw rod and the reducer. At this time, the second feeding clamp and the first feeding clamp move to the right, and the second feeding clamp is reset. At this time, the first feeding clamp and the second feeding clamp are exchanged again under the action of the third gear and the toothed plate, so that the bolt on the second feeding clamp is placed in the second feeding clamp, and the effect of automatic feeding is achieved;

[0019] 4. In the present invention, when the first feeding clamp moving frame moves to the right to the second feeding clamp position, the cam plate corresponding to the first feeding clamp pulls the roller through the track groove, and the roller drives the first movable rod and the second movable rod to realize the rotation and pressing structure to rotate upward, so as to ensure that the first feeding clamp is in a vertical state through the steering structure. When the steering structure drives the first feeding clamp to move upward, the clamping block slides upward along the pressing frame, and the guide rod moves along the guide groove provided on the fixed plate, thereby effectively ensuring that the first feeding clamp rotates from a horizontal state to a vertical state. After the first feeding clamp completes the feeding, the first feeding clamp moves between the two rolling wheels to realize the reset feeding of the second feeding clamp.

[0020] When the second feeding clamp moves to the two thread rolling wheels, the two clamping plates of the first feeding clamp contact with the limiting wheel at the end of the connecting rod on one side of the mounting shell, thereby effectively realizing the opening of the first feeding clamp under the action of resistance, and placing the bolt between the two thread rolling wheels. When the second feeding clamp moves to the two thread rolling wheels, the same effect is achieved through the corresponding cam plates, the rotating pressing structure and the steering structure.

[0045] The two cross bars 43 are fixedly mounted with a fixing plate 7 at one end close to the thread rolling assembly 2; a guide groove 10 is provided on the fixing plate 7; a pressing structure 11 is movably mounted on the inner side of the fixing plate 7 via a rotating shaft; the pressing structure 11 comprises a cylinder 110; a push rod 111 and a pressure frame 112 are integrally provided on the surface of the cylinder 110; the end of the push rod 111 away from the cylinder 110 is movably connected to the second movable rod 47 via a rotating shaft.

[0046] By adopting the above technical solution, when in use, the transmission and feeding of the screw to be processed is realized through the vibration plate 3, and the steering structure 9 at the end of the cross bar 43 is realized by the left and right movement of the mobile frame 42 to realize the flipping of the direction of the first feeding clamp 8 and the second feeding clamp 14 in the cooperation with the pressing structure 11. In the process of the left and right movement of the mobile frame 42, the tooth plate 65 cooperates with the third gear 64 to realize the rotation and alternating feeding of the first feeding clamp 60 and the second feeding clamp 61 at the top of the rotating plate 62, thereby effectively improving the feeding efficiency;

[0047] See also Figure 1-15 ; A steering structure 9 is movably installed inside the press frame 112; the steering structure 9 includes a rectangular block 90; a clamping block 92 is integrally provided at one end of the rectangular block 90; the clamping block 92 is slidably connected to the press frame 112; a guide rod 93 is provided at one end of the clamping block 92 away from the rectangular block 90; the guide rod 93 is installed in cooperation with the guide groove 10 provided on the fixing plate 7; the press frame 112 is located between the guide rod 93 and the rectangular block 90.

[0048] In this embodiment, a mounting rod 91 is fixedly mounted on the rectangular block 90 on the adjacent surface of the clamp block 92; the first loading clamp 8 and the second loading clamp 14 are mounted on the mounting rod 91; the loading clamp 8 and the second loading clamp 14 each include two clamping plates of the same structure; a torsion spring 12 is mounted between the loading clamp 8 and the second loading clamp 14 and the mounting rod 91;

[0049] By adopting the above technical solution, in the feeding, the reducer 44 drives the screw rod 41 to rotate, and the screw rod 41 realizes the left and right movement of the moving frame 42 and the cross bar 43. During the movement, the second drive motor 52 drives the rotating shaft 53 to rotate through the connecting belt 54, and the cam plates 51 at both ends of the rotating shaft 53 rotate. The two cam plates 51 are set at 90 degrees. In this way, when the cam plates 51 rotate, the cam plates 51 can effectively realize the alternate pressing structure 11 driving the steering structure 9 to adjust the position of the feeding clamp 8;

[0050] See also Figure 1-15 ; In this embodiment, the top of the cross bar 43 is equipped with a driving assembly 5 through a bracket; the driving assembly 5 includes two cam plates 51 arranged at 90 degrees; the surface of the cam plate 51 is provided with a track groove 51; the track groove 51 is slidably matched with the roller 45 at the end of the first movable rod 46; the two cam plates 51 are fixedly installed with the rotating shaft 53; the middle of the rotating shaft 53 is equipped with a second driving motor 52 through a connecting belt 54; the second driving motor 52 is fixedly installed on the moving frame 42;

[0051] The movable frame 42 is located at the bottom of the fixed plate 7 and fixedly installed with the tooth plate 65 in the feeding assembly 6; the feeding assembly 6 also includes a support shaft 63; the support shaft 63 is movably installed with the workbench inside the housing 1 through a bearing; a rotating plate 62 is installed on the top of the support shaft 63; the first feeding clamp 60 and the second feeding clamp 61 are fixedly installed at both ends of the rotating plate 62; a third gear 64 is also fixedly installed on the support shaft 63; one side of the third gear 64 is meshed with the tooth plate 65;

[0052] When the first and second material feeding clamps 8 are in the state of being moved to the right by the movable frame 42, the first material feeding clamp 8 and the second material feeding clamp 14 are reset. At this time, the first material feeding clamp 60 and the second material feeding clamp 61 are exchanged again under the action of the third gear 64 and the toothed plate 65, so that the bolt on the second material feeding clamp 61 is placed in the second material feeding clamp 14, thereby achieving the effect of automatic feeding.

[0053] See also Figure 1-20 In this embodiment, the first feeding jaw 60 and the second feeding jaw 61 cooperate with the first feeding clamp 8, the second feeding clamp 14 and the vibration plate 3; the vibration plate 3 is placed on the workbench inside the housing 1;

[0054] By adopting the above technical scheme, when the moving frame 42 of the first feeding clamp 8 moves to the right to the position of the second feeding clamp 14, the cam plate 51 corresponding to the first feeding clamp 8 pulls the roller 45 through the track groove 51, and the roller 45 drives the first movable rod 46 and the second movable rod 47 to realize the upward rotation of the rotary pressing structure 11, so as to ensure that the first feeding clamp 8 is in a vertical state through the steering structure 9. When the steering structure 9 drives the first feeding clamp 8 to move upward, the clamping block 92 slides upward along the pressing frame 112, and the guide rod 93 moves along the guide groove 10 provided on the fixed plate 7, so as to effectively ensure that the first feeding clamp 8 rotates from a horizontal state to a vertical state. After the first feeding clamp 8 is loaded, the first feeding clamp 8 moves between the two thread rolling wheels 21 to realize the reset loading of the second feeding clamp 14.

[0055] Furthermore, when the first feeding clamp 8 moves between the two thread rolling wheels 21, the second driving motor 52 drives the rotating shaft 53 to realize that the cam plate 51 corresponding to the first feeding clamp 8 pushes the roller 45 at the end of the first movable rod 46 through the track groove 51, so that the first movable rod 46 and the second movable rod 47 drive the push rod 111 to tilt upward, and the push rod 111 drives the pressing frame 112 to press down through the cylinder 110. When the pressing frame 112 is pressed down, the clamping block 92 at the end of the rectangular block 90 is moved, and the clamping block 92 moves downward along the pressing frame 112. At the same time, the guide rod 93 on one side of the clamping block 92 moves along the guide rod 93 provided on the fixing plate 7. When the first loading clamp 8 moves downwardly toward the groove 10, the first loading clamp 8 on the mounting rod 91 is rotated from a vertical state to a horizontal state during the process of the first loading clamp 8 moving downwardly, the two clamping plates of the first loading clamp 8 contact the limiting wheel 28 at the end of the connecting rod 27 on one side of the mounting shell 20, thereby effectively realizing the first loading clamp 8 opening under the action of resistance, placing the bolt between the two rolling wheels 21, and when the second loading clamp 14 moves to the two rolling wheels 21, the same effect is achieved through the corresponding cam disc 51, the rotating pressing structure 11 and the steering structure 9;

[0056] In this embodiment, the slide rail 26 is fixedly mounted on the workbench inside the cover 1, and the top of the movable plate 24 on the same side of the two mounting shells 20 is movably mounted with the push rod of the electric push cylinder 22; the electric push cylinder 22 is fixedly mounted on the top of the support rod 23; the bottom of the support rod 23 is fixedly mounted with the slide rail 26; one of the first gears 29 on one side of the mounting shell 20 is connected to the first drive motor 25; the first drive motor 25 is fixedly mounted on the movable plate 24;

[0057] By adopting the above technical solution, when processing bolts, when workpieces of different sizes need to be processed, the movable plate 24 is driven to rotate outward or inward by the electric push cylinders 22 corresponding to the two mounting shells 20, so as to effectively adjust the distance between the two rolling wheels 21. When the distance between the two rolling wheels 21 changes, the meshing position between the second gear 210 on the side of the first gear 29 set on one side of the mounting shell 20 and the matching gear 213 changes, and the matching gear 213 is offset left and right through the second connecting plate 212 to achieve effective meshing with the two second gears 210. After the rolling wheel 21 completes the thread rolling of the bolt, the processed bolt falls on the unloading rack 13 at the bottom between the rolling wheels 21, and is automatically unloaded and transmitted through the unloading rack 13.

[0058] The working principle of the present invention is as follows: when in use, the transmission and feeding of the screw to be processed is realized through the vibration plate 3, and the steering structure 9 at the end of the cross bar 43 is realized by the left and right movement of the mobile frame 42 to realize the flipping of the direction of the first feeding clamp 8 and the second feeding clamp 14 in the cooperation with the pressing structure 11. In the process of the left and right movement of the mobile frame 42, the tooth plate 65 cooperates with the third gear 64 to realize the rotation and alternating feeding of the first feeding clamp 60 and the second feeding clamp 61 at the top of the rotating plate 62, thereby effectively improving the feeding efficiency;

[0059] In feeding, the reducer 44 drives the screw rod 41 to rotate, and the screw rod 41 realizes the left and right movement of the moving frame 42 and the cross bar 43. During the movement, the second drive motor 52 drives the rotating shaft 53 to rotate through the connecting belt 54, and the cam plates 51 at both ends of the rotating shaft 53 rotate. The two cam plates 51 are set at 90 degrees. In this way, when the cam plates 51 rotate, the cam plates 51 can effectively realize the alternate pressing structure 11 to drive the steering structure 9 to adjust the position of the feeding clamp 8;

[0060] When the moving frame 42 moves to one side of the vibration plate 3, the first feeding clamp 8 and the second feeding clamp 14 move synchronously. At this time, the third gear 64 and the toothed plate 65 connected to the moving frame 42 are meshed, so that the first feeding clamp 60 close to the side of the vibration plate 3 is rotated by the rotating shaft 63. At this time, the first feeding clamp 8 moves to the position of the second feeding clamp 14, and the second feeding clamp 14 moves to one side of the supporting shaft 63. At this time, the first feeding clamp 60 places the bolt in the first feeding clamp 8. After the feeding is completed, the moving frame 42 moves to the right under the action of the screw rod 41 and the reducer 44. At this time, the second feeding clamp 14 and the first feeding clamp 8 move to the right, and the second feeding clamp 14 is reset. At this time, the first feeding clamp 60 and the second feeding clamp 61 are exchanged again under the action of the third gear 64 and the toothed plate 65, so that the bolt on the second feeding clamp 61 is placed in the second feeding clamp 14, and the effect of automatic feeding is achieved;

[0061] When the moving frame 42 of the first feeding clamp 8 moves to the right to the position of the second feeding clamp 14, the cam plate 51 corresponding to the first feeding clamp 8 pulls the roller 45 through the track groove 51, and the roller 45 drives the first movable rod 46 and the second movable rod 47 to realize the upward rotation of the rotary pressing structure 11, so as to ensure that the first feeding clamp 8 is in a vertical state through the steering structure 9. When the steering structure 9 drives the first feeding clamp 8 to move upward, the clamping block 92 slides upward along the pressing frame 112, and the guide rod 93 moves along the guide groove 10 provided on the fixed plate 7, so as to effectively ensure that the first feeding clamp 8 rotates from a horizontal state to a vertical state. After the first feeding clamp 8 is loaded, the first feeding clamp 8 moves between the two rolling wheels 21 to realize the reset loading of the second feeding clamp 14.

[0062] When the first feeding clamp 8 moves between the two thread rolling wheels 21, the second driving motor 52 drives the rotating shaft 53 to realize that the cam plate 51 corresponding to the first feeding clamp 8 pushes the roller 45 at the end of the first movable rod 46 through the track groove 51, so that the first movable rod 46 and the second movable rod 47 drive the push rod 111 to tilt upward, and the push rod 111 drives the pressing frame 112 to press down through the cylinder 110. When the pressing frame 112 is pressed down, the clamping block 92 at the end of the rectangular block 90 is moved, and the clamping block 92 moves downward along the pressing frame 112. At the same time, the guide rod 93 on one side of the clamping block 92 moves along the guide groove 112 opened on the fixing plate 7. 0 slides downward, and in the process of the rectangular block 90 driving the mounting rod 91 to move, the first loading clamp 8 on the mounting rod 91 is rotated from a vertical state to a horizontal state. In the process of the first loading clamp 8 moving downward, the two clamping plates of the first loading clamp 8 contact the limiting wheel 28 at the end of the connecting rod 27 on one side of the mounting shell 20, so that the first loading clamp 8 is effectively opened under the action of resistance, and the bolt is placed between the two rolling wheels 21. When the second loading clamp 14 moves to the two rolling wheels 21, the same effect is achieved through the corresponding cam disc 51, the rotating pressing structure 11 and the steering structure 9;

[0063] During bolt processing, when workpieces of different sizes need to be processed, the movable plate 24 is driven to rotate outward or inward by the electric push cylinders 22 corresponding to the two mounting shells 20, thereby effectively adjusting the distance between the two rolling wheels 21. When the distance between the two rolling wheels 21 changes, the meshing position between the second gear 210 on the side of the first gear 29 set on one side of the mounting shell 20 and the mating gear 213 changes, and the mating gear 213 is offset left and right through the second connecting plate 212 to achieve effective meshing with the two second gears 210. After the rolling wheel 21 completes the thread rolling of the bolt, the processed bolt falls onto the unloading rack 13 at the bottom between the rolling wheels 21, and is automatically unloaded and transmitted through the unloading rack 13.
