Description

Technical Field

[0001] This utility model belongs to the field of tube and bar processing and forging technology, and specifically relates to a clamping and feeding mechanism. Background Technology

[0002] Forging is an important metal forming process. It involves preheating and pressurizing tubular or bar stock to induce plastic deformation, thereby obtaining the shaped workpiece. Forged parts have a denser metal microstructure, significantly improving their plasticity and mechanical properties. Furthermore, forging ensures the continuity of the metal's fibrous structure and maintains consistency with the forging's shape, resulting in more uniform metal plastic forming and reducing the need for secondary processing. Currently, most tubular and bar processing companies still use radial forging equipment and manual feeding. Workers clamp one end of the tubular or bar stock and feed it into the forging equipment, simultaneously rotating it to complete the entire forging and plastic forming process. This existing feeding method is labor-intensive, poses significant safety hazards, and severely reduces the finished product yield, failing to meet actual production needs. Utility Model Content

[0028] In some embodiments, the track mechanism includes two parallel linear guide rails 9; each of the two linear guide rails 9 is provided with a slider; the two linear guide rails 9 are slidably connected to the bottom surface of the adjusting clamping mechanism through the sliders.

[0029] In practical use, this technical solution uses a cylinder to drive the adjusting clamping mechanism to feed material axially on the track mechanism, which can strictly control the feed amount of the tube and bar billet during the forging process, thereby achieving controllability of forming process parameters.

[0030] In some embodiments, the adjusting part is connected between the clamping mechanism 16 and the cylinder 1; the adjusting part is slidably connected to the track mechanism.

[0031] In actual use, the adjustment unit is used to adjust the clamping mechanism 16 to stably clamp the billet and rotate the billet at the forging station, thereby ensuring the forging quality.

[0032] In some embodiments, the adjustment unit includes a first servo motor 2, a frame 3, a first gear 4, a first shaft 5, a second gear 6, a second shaft 7, a second servo motor 8, a coupling 10, a third gear 11, a third shaft 12, a worm gear 13, a worm 14, and a gear sleeve 15; the frame 3 is connected to the first shaft 5, the second shaft 7, and the third shaft 12, which are arranged in parallel and parallel to the output shaft of the cylinder 1; the second shaft 7 is arranged perpendicularly to and offset from the first shaft 5 and the third shaft 12; the first servo motor 2 and the second servo motor 8 are connected to the frame. On one side panel of 3; the output shaft of the first servo motor 2 passes through the panel and is connected to the first gear 4; the first gear 4 meshes with the third gear 11; the third gear 11 is fixedly connected to the first shaft 5; a gear sleeve 15 is provided axially on the first shaft 5, and the gear sleeve 15 extends into the clamping mechanism 16; the gear sleeve 15 meshes with the clamping mechanism 16 and the second gear 6 installed on the second shaft 7 respectively; a worm gear 14 is installed on the third shaft 12, and the worm gear 14 meshes with the worm wheel 13 installed on the second shaft 7; the third shaft 12 is connected to the second servo motor 8 through a coupling 10.

[0033] Furthermore, the clamping mechanism 16 includes a fourth gear 161, a clamping part, a fourth shaft 163, and a frame 164; the fourth shaft 163 is horizontally connected inside the frame 164, and its axis is perpendicular to the output shaft of the cylinder 1; the fourth gear 161 is installed at the middle position of the fourth shaft 163; one end of the clamping part is threadedly connected to the fourth shaft 163, and the other end extends to the outside of the frame 164; the frame 164 is detachably connected to the first shaft 5.

[0034] In practical applications, the first shaft 5 is fixed to the frame 164 by screws 165.

[0035] Furthermore, the clamping part includes two parallel clamping arms 162; the two clamping arms 162 are respectively connected to the two ends of the fourth shaft 163; one end of each clamping arm 162 is provided with a threaded hole for threaded connection with the fourth shaft 163 and the threaded hole is an internal thread, and the other end is arc-shaped, and the arcs of the ends of the two clamping arms 162 are arranged opposite to each other.

[0036] Furthermore, both ends of the fourth shaft 163 are designed to be threaded, with one end being forward-rotating and the other end being reverse-rotating.

[0037] The working principle of this utility model is as follows: Air enters through port A and exits through port B of cylinder 1, pushing the frame 3 forward on the linear guide rail 9 to the blank waiting position. The second servo motor 8 drives the coupling 10 to rotate the third shaft 12 axially. At this time, the worm gear 14 mounted on the third shaft 12 drives the worm wheel 13 to rotate, causing the second shaft 7 to rotate, thereby causing the second gear 6 to rotate clockwise along the axis of the second shaft 7. Driven by the second gear 6, the gear sleeve 15 moves linearly along the first shaft 5 axially. At this time, the gear sleeve 15 drives the fourth gear 161 to rotate. The rotation of the fourth gear 161 drives the fourth shaft 163 to rotate, thus causing the two ends of the fourth shaft 163 to rotate clockwise and counterclockwise. The threaded connection drives two clamping arms 162 to move axially along the fourth axis 163, thereby clamping the tube / bar billet by the clamping mechanism 16. After the clamping mechanism 16 clamps the tube / bar billet, the air intake at port A and the air outlet at port B of cylinder 1 pushes the frame 3 forward on the linear guide rail 9, sending the billet to the radial forging station. The forging equipment begins forging the billet, the first servo motor 2 operates, driving the first gear 4 to rotate, and the first gear 4 meshes with and drives the third gear 11 to rotate. The first shaft 5 rotates axially under the rotation of the third gear 11, while the air intake at port A and the air outlet at port B of cylinder 1 push the frame 3 and the clamping mechanism 16 to move axially along the linear guide rail 9. The guide rail 9 moves forward, allowing the billet to be fed axially while rotating circumferentially. Since the first shaft 5 is fixed to the frame 164, the clamping mechanism 16 rotates with the first shaft 5. After the forging process of the billet is completed, the first servo motor 2 stops working, and the clamping mechanism 16 stops rotating. Air enters through port B and exits through port A of cylinder 1, pulling the frame 3 backward on the linear guide rail 9 to exit the forging station. When cylinder 1 drives the frame 3 to the unloading station, the second servo motor 8 rotates in the opposite direction, driving the coupling 10 to rotate the third shaft 12 in the opposite direction axially. The worm gear 14 installed on the upper drive the worm wheel 13 to rotate in the opposite direction, thereby causing the second shaft 7 to rotate, so that the second gear 6 rotates counterclockwise along the axis of the second shaft 7; under the drive of the second gear 6, the gear sleeve 15 moves linearly away from the servo motor along the axis of the first shaft 5; at this time, the gear sleeve 15 drives the fourth gear 161 to rotate counterclockwise; the rotation of the fourth gear 161 drives the fourth shaft 163 to rotate, so that the forward and reverse threads at both ends of the fourth shaft 163 drive the two clamping arms 162 to move towards both ends along the axis of the fourth shaft 163 through the threaded connection, thereby the clamping mechanism 16 releases the tube and bar billet, realizing the unloading action after the forging process is completed.

[0038] In some embodiments, the frame 3 is a right-angled U-shaped structure composed of two side plates 31 and a base plate 35, with the opening of the U-shaped structure facing upwards; two opposing third mounting plates 34 for connecting the second shaft 7 are connected to one side of the upper surface of the base plate 35; a first mounting plate 32 for fixing the first shaft 5 is connected to the other side of the upper surface of the base plate 35; a second mounting plate 33 for fixing the third shaft 12 is connected to the upper surface of the base plate 35 between the first mounting plate 32 and the third mounting plate 34; a first servo motor 2 and a second servo motor 8 are connected to the side plate 31 near the first mounting plate 32, and a clamping mechanism 16 is provided on the outer side of the side plate 31 near the third mounting plate 34.

[0039] In actual use, the frame 3 adopts the above technical solution, which can easily and stably connect the components required by the adjustment section, ensuring the smooth operation of the clamping and feeding device.

[0040] This invention uses one servo motor to control the opening and closing of the clamping arm, and another servo motor to drive the rotation of the clamping device. With the help of a cylinder and linear guide rail, the tube and bar billet is clamped and fed along the axial direction. This satisfies the requirement that the clamping and feeding mechanism feeds the tube and bar billet along the axial direction while rotating it in the circumferential direction. This greatly solves the problem of high manual labor intensity, while increasing the coaxiality and surface finish of the finished product, thereby reducing the prominent problems of secondary processing.

[0041] This invention utilizes dual servo motors for clamping and rotation, enabling flexible clamping of tube and bar billets while simultaneously controlling the rotation angle precision during forging. This significantly reduces dimensional errors in the finished product after forging, lowers the defect rate, and thus greatly improves product quality.

[0042] This invention uses a cylinder to drive a support to feed material axially along a linear guide assembly, which can strictly control the feed amount of the tube and bar billet during the forging process, thereby achieving controllability of the forming process parameters.

[0043] Compared with traditional manual clamping and feeding of forgings, this utility model significantly reduces the intensity of manual labor, reduces the rate of defective scrap, and greatly improves the economic benefits of enterprises.
