Description

[0002] In the field of mechanical manufacturing, rods with cylindrical structures at the ends are key components and are widely used in various industrial products. Before the cylindrical structure at the end of the rod is pressed, in order to improve the plasticity of the rod and reduce its hardness, it is usually necessary to heat the end first, and then transport it to the press through a conveying mechanism for pressing.

[0003] Currently, after heating, the bar is clamped by a robot to a conveying mechanism and then transferred to a press for punching. When the bar arrives at the press, the angle of its end needs to be manually adjusted to ensure that it is in a horizontal state to meet the requirements of the punching operation. Manual operation not only increases labor costs, but also exposes operators to potential dangers such as burns and collisions. To this end, we propose a bar conveying and correction device.

DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] Refer to the attached Figure 1-7 A bar conveying and correction device includes a ground rail 1 and an L-shaped cantilever beam 2 arranged on one side thereof, both of which are fixed to the ground by a number of bolts. The crossbeam at the top of the L-shaped cantilever beam 2 extends above the ground rail 1 to form a horizontal spanning structure. The ground rail 1 is provided with a carrying plate 3 that moves along its direction for carrying and transporting the bar. The L-shaped cantilever beam 2 is provided with a traveling frame 21 that can move along the direction of its top crossbeam. The traveling frame 21 is provided with a pair of calibration plates 22 that can move toward or in opposite directions to calibrate the ends of the bar to keep it in a horizontal state. The heated bar is placed on the carrying plate 3 by a manipulator. 3 moves on the ground rail 1 and moves the cylindrical structure at the end of the bar to between a pair of calibration plates 22. Then, the two calibration plates 22 are controlled to move toward each other and clamp the cylindrical structure at the end of the bar so that the surface of the cylindrical structure at the end of the bar remains horizontal. Then, the calibration plates 22 are released and the traveling frame 21 is controlled to move along the crossbeam at the top of the L-shaped cantilever beam 2 to make way for the bar to pass. Then, the carrying plate 3 is controlled to drive the bar to move so that the cylindrical structure at the end of the bar moves to the bottom of the press for punching and punching. There is no need to manually adjust the angle of the bar, which is safe, efficient and highly automated.

[0031] There are two groups of supporting plates 3, and the two groups of supporting plates 3 can slide together in a linked manner or slide individually, so as to stably convey bars of different lengths.

[0032] In this embodiment, a receiving groove 221 is provided in the calibration plate 22, and a support shaft 222 is fixed in the receiving groove 221 in the same direction as the bar material conveying direction. The outer wall of the support shaft 222 is rotatably connected to a rotating plate 223 that can rotate in the receiving groove 221. The two sides of the rotating plate 223 are connected to the inner cavity of the receiving groove 221 through a torsion spring 224, so that the rotating plate 223 is tilted in the initial state. A baffle 225 is provided on the calibration plate 22, and the baffle 225 is arranged on one side above the receiving groove 221 to limit the rotating plate 223 after rotation, so that the bottom of the rotating plate 223 after rotation remains in a horizontal state, and the two calibration plates 22 move toward each other. When clamping and correcting the end of the bar, the rotating plate 223 will first contact the cylindrical structure at the end of the bar. When the plane of the cylindrical structure at the end of the bar is in a vertical state, the inclined rotating plate 223 will first push the bar to rotate, so that the plane of the cylindrical structure at the end of the bar gradually changes from a vertical state to a horizontal state. As the two calibration plates 22 gradually approach and clamp the cylindrical structure at the end of the bar, the plane of the circular structure at the end of the bar is horizontal, and then the outer wall of the bar is clamped by the clamping mechanism, so that the two calibration plates 22 are released after the bar is fixed to complete the calibration of the end of the bar. No matter at what angle the bar is placed, calibration can be easily achieved, and it has extremely strong adaptability and flexibility.

[0033] In this embodiment, a first guide rail 23 is provided on both sides of the walking frame 21, and a slider 24 is provided on the back of each calibration plate 22. A first bidirectional cylinder 25 is provided between the two sliders 24, so that the two sliders 24 move toward or oppositely in the vertical direction along the first guide rail 23. When the first bidirectional cylinder 25 is started, the two sliders 24 move toward or oppositely along the first guide rail 23, further causing the two calibration plates 22 to move toward or oppositely, thereby facilitating the calibration of the ends of the bar.

[0034] In this embodiment, a first traveling motor 211 and a first traveling gear 213 are provided on the traveling frame 21. The output end of the first traveling motor 211 drives the first traveling gear 213 to rotate through a belt 212. A first rack 26 is provided on the L-shaped cantilever beam 2 to cooperate with the first traveling gear 213, so that the traveling frame 21 moves along the crossbeam direction of the L-shaped cantilever beam 2 to make room for the movement of the bar material. The first traveling motor 211 is started. At this time, the belt 212 drives the first traveling gear 213 to rotate. At this time, the traveling frame 21 moves along the crossbeam direction of the L-shaped cantilever beam 2 with the cooperation of the first rack 26, so as to make room for the movement of the bar material toward the press direction, and the degree of automation is high.

[0035] In this embodiment, a second guide rail 27 is provided at the bottom of the crossbeam of the L-shaped cantilever beam 2 for the traveling frame 21 to move along the crossbeam direction. The traveling frame 21 moves on the second guide rail 27, and the movement is more stable.

[0036] In this embodiment, a pair of support rollers 31 and a clamping mechanism for clamping the outer wall of the bar are provided on the supporting plate 3. The bar is placed on the support rollers 31 and then clamped by the clamping mechanism to prevent the bar from being deflected after transportation or calibration, thereby improving the subsequent processing accuracy.

[0037] In this embodiment, the clamping mechanism includes a second bidirectional cylinder 321, and the two output ends of the second bidirectional cylinder 321 are connected to clamping plates 322. The two clamping plates 322 move toward each other to clamp the outer wall of the bar. When the second bidirectional cylinder 321 is started, the clamping plates 322 on both sides can clamp the bar to prevent the bar from deflecting or falling during transportation.

[0039] In this embodiment, a second travel motor 34 is provided on the supporting plate 3, and a transmission gear 35 is provided at the output end of the second travel motor 34. The outer wall of the transmission gear 35 is meshed with the second travel gear 36. A second rack 11 is provided in the ground rail 1 to match the second travel gear 36. The second rack 11 is consistent with the direction of the ground rail 1, so that the supporting plate 3 can move along the direction of the ground rail 1. Its second travel motor 34, at this time, the transmission gear 35 drives the second travel gear 36 to rotate. At this time, with the cooperation of the second rack 11, the supporting plate 3 moves along the direction of the ground rail 1, which is convenient for conveying the bar material.

[0040] In this embodiment, the diameter of the transmission gear 35 is smaller than the diameter of the second traveling gear 36, and the relative rotation speed of the second traveling gear 36 is smaller than the rotation speed of the transmission gear 35, which is convenient for reducing the movement speed of the supporting plate 3 on the ground rail 1, avoiding the supporting plate 3 from moving too fast, and ensuring smooth and safe operation.
