Description

Technical Field

[0001] The invention relates to the technical field of conveying, and in particular to a metal rod conveying device. Background Art

[0002] Metal bar is a commonly used bar material. Before use, it needs to go through smelting, casting, quenching and surface treatment. Quenching is a heat treatment process that aims to change the crystal structure of the metal through rapid cooling, thereby adjusting its hardness and strength.

[0003] In the metal bar processing workshop, after quenching the metal bars, it is often necessary to water cool the high-temperature metal bars and then convey them to other process equipment through rollers for the next step of processing. The traditional conveyor roller can only realize the forward movement of the metal bars during the conveying process, but cannot realize the rotation of the metal bars during the forward movement, thereby avoiding the metal bars always contacting the roller at one position, resulting in overheating and black spots caused by accumulation of metal bars.

[0004] In order to solve the above problems, we proposed a metal rod conveying device. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a metal rod conveying device.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a metal rod conveying device, comprising a workbench, a mounting groove is provided on the workbench, a plurality of conveying rollers are evenly distributed in the mounting groove, and a pushing mechanism and a flipping mechanism are sequentially arranged on the workbench; The cam is an angular channel that is slidably connected to the top of the workbench and is provided with a rotating plate, and the rotating plate is connected to the cam face, and the rotating plate is connected to the cam face by a toothed connection.

[0007] In the above-mentioned metal rod conveying device, the pushing mechanism includes a center plate one and a center plate two which are symmetrically fixed on the side walls of the workbench, a push plate is slidably inserted in the middle of the center plate one, a through opening is opened in the middle of the center plate two, a rotating plate is arranged in the through opening, a motor is fixed to the upper side wall of the center plate two, a driving end of the motor passes through the upper side wall of the center plate two and is fixedly connected to the rotating plate, a pillar is fixedly connected to the end of the rotating plate, a connecting rod is fixedly connected to the upper end of the pillar, a guide frame is fixedly connected to the upper side wall of the center plate one, a moving frame is slidably inserted in the guide frame, the end of the moving frame is located on the outside of the push plate, and the other end of the moving frame is rotatably connected to the end of the connecting rod away from the pillar.

[0008] In the above-mentioned metal rod conveying device, the lower side wall of the workbench is fixedly connected to a support rod, the end of the support rod is fixedly connected to a support plate, the lower side wall of the support plate is fixedly connected to a liquid pump, and the upper side wall of the support plate is provided with a groove, in which a nozzle connected to the liquid pump and arranged toward the workbench is fixed.

[0009] In the above-mentioned metal rod conveying device, the distance between the ends of the centering plate 1 and the centering plate 2 gradually decreases, and the distance between the ends of the centering plate 1 and the centering plate 2 close to the fixed plate 1 is smaller than the distance between the ends away from the fixed plate 1.

[0010] In the above-mentioned metal rod conveying device, a gap is provided between the fixed plate 1 and the ends of the fixed plate 2, and the size of the gap is equal to the minimum distance between the center plate 1 and the ends of the center plate 2.

[0011] In the above-mentioned metal rod conveying device, an inclined surface is provided on the outer wall of one end of the push plate away from the first fixing plate and the second fixing plate.

[0012] In the above-mentioned metal rod conveying device, the motor is a stepping motor.

[0013] Compared with the existing technology, the advantages of the metal rod conveying device are: The motor drives the rotating plate to rotate back and forth. The end of the rotating plate located on the upper side of the workbench rotates toward the side away from the fixed plate, pushing the end of the metal rod to move toward the end of the workbench. The end of the rotating plate located on the outer side of the workbench rotates toward the side away from the workbench, pulling the connecting rod, the moving frame and the push plate to move toward the center line of the workbench, pushing the other end of the metal rod to move toward the center line of the workbench, so that the center line of the metal rod is almost consistent with the center line of the workbench. The motor drives the turntable to rotate, and when the turntable drives the end of the connecting plate to rotate toward the side away from the right-angle plate, the connecting plate, the movable rod, the vertical tube and the right-angle trapezoidal plate are pulled to move toward one side of the turntable. At this time, the surface height of the right-angle trapezoidal plate in contact with the end of the extrusion rod increases, and then the extrusion rod squeezes the right-angle trapezoidal plate to move downward, that is, the vertical tube moves downward on the outer wall of the movable rod, so that the right-angle trapezoidal plate moves to one side and moves downward at the same time, and contacts with the metal rod after moving downward. After contact, when the right-angle trapezoidal plate moves outward, it drives the metal rod to rotate through friction, so that the metal rod is turned over, which avoids the metal rod always contacting the conveying roller at one position, and avoids the generation of black spots. In summary, the present invention realizes intermittent rotation of the metal rod by conveying the metal rod forward and intermittently contacting the metal rod with the right-angle trapezoidal plate during the conveying process, thereby avoiding the metal rod always contacting the conveying roller at one position, thereby avoiding the generation of black spots on the surface of the metal rod and ensuring the quality of the metal rod.

DETAILED DESCRIPTION

[0016] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Reference Figure 1-Figure 3, a metal rod conveying device comprises a workbench 1, a mounting groove is opened on the workbench 1, and a plurality of conveying rollers 2 are evenly distributed in the mounting groove. A pushing mechanism and a flipping mechanism are sequentially arranged on the workbench 1, and the pushing mechanism comprises a centering plate 1 3 and a centering plate 2 5 which are symmetrically fixedly arranged on the upper side wall of the workbench 1, a pushing plate 4 is slidably inserted in the middle of the centering plate 1 3, a through opening is opened in the middle of the centering plate 2 5, and a rotating plate 8 is arranged in the through opening, and a motor 6 is fixed on the upper side wall of the centering plate 2 5, and the motor 6 adopts a stepping motor, and the stepping motor is connected to a controller, and a pulse signal is set by the controller to realize the reciprocating rotation of the driving end of the motor 6 within a certain angle, and the controller can also be connected to a limit switch or an encoder, when the motor 6 reaches the set angle range, the limit switch or the encoder will send a signal to the controller, and the controller stops sending the pulse signal, thereby stopping the rotation of the motor 6, and realizing the reciprocating rotation of the driving end of the motor 6 through the upper control, thereby driving the rotating plate 8 to swing back and forth within a certain angle range.

[0018] The driving end of the motor 6 passes through the upper side wall of the center plate 2 5 and is fixedly connected to the rotating plate 8. The end of the rotating plate 8 is fixedly connected to a pillar 9, and the upper end of the pillar 9 is fixedly connected to a connecting rod 10. The upper side wall of the center plate 3 is fixedly connected to a guide frame 11. A moving frame 12 is slidably inserted in the guide frame 11. The end of the moving frame 12 is located on the outer side of the push plate 4. The other end of the moving frame 12 is rotatably connected to the end of the connecting rod 10 away from the pillar 9. An inclined surface 7 is provided on the outer wall of the end of the push plate 4 away from the fixed plate 1 13 and the fixed plate 2 14. The setting of the inclined surface 7 has a guiding effect on the metal rod 26. The quenched metal rod 26 is placed on the workbench 1, and the metal rod 26 is driven forward by the rotation of the conveying roller 2. In order to facilitate the subsequent pushing of the metal rod 26 for rotation, the direction of the metal rod 26 is changed by the pushing mechanism, so that the metal rod 26 and the center line of the workbench 1 are located in a nearly straight line, so that it can smoothly pass between the fixed plate 1 13 and the fixed plate 2 14; The pushing method of the pushing mechanism: the metal rod 26 is conveyed forward by the rotation of the conveying roller 2, and the motor 6 drives the rotating plate 8 to rotate back and forth. The end of the rotating plate 8 located on the upper side of the workbench 1 rotates toward the side away from the fixed plate 13, pushing the end of the metal rod 26 to move toward the end of the workbench 1, and the end of the rotating plate 8 located on the outer side of the workbench 1 rotates toward the side away from the workbench 1, pulling the connecting rod 10, the moving frame 12 and the push plate 4 to move toward the center line of the workbench 1, pushing the other end of the metal rod 26 to move toward the center line of the workbench 1. By combining the two pushing methods, the metal rod 26 is changed from a messy state to a state consistent with the center line of the workbench 1, and then conveyed forward, while avoiding the metal rod 26 from being stuck between the center plate 1 3 and the center plate 2 5, so that the metal rod 26 can be continuously and stably conveyed forward; The flipping mechanism includes a fixed plate 13 and a fixed plate 2 14 which are symmetrically fixed on the upper side wall of the workbench 1. The distance between the ends of the centering plate 1 3 and the centering plate 2 5 gradually decreases. The distance between the ends of the centering plate 1 3 and the centering plate 2 5 close to the fixed plate 13 is smaller than the distance between the ends away from the fixed plate 13. A gap is provided between the ends of the fixed plate 13 and the fixed plate 2 14. The size of the gap is equal to the minimum distance between the ends of the centering plate 1 3 and the centering plate 2 5. The distance between the centering plate 1 3 and the centering plate 2 5 gradually decreases. The metal rod 26 can achieve a centering effect after passing through the centering plate 1 3 and the centering plate 2 5, so that the metal rod 26 can smoothly enter between the fixed plate 1 13 and the fixed plate 2 14 after being transported forward.

[0019] A right-angle plate 18 is fixedly connected to the fixed plate 14, and a right-angle trapezoidal plate 19 is slidably sleeved on the end of the right-angle plate 18. A vertical tube 21 is fixedly connected to the upper side wall of the right-angle trapezoidal plate 19, and a movable rod 20 is slidably inserted into the upper end of the vertical tube 21. A telescopic spring is fixedly connected between the movable rod 20 and the inner bottom wall of the vertical tube 21. The end of the fixed plate 14 away from the fixed plate 13 is fixedly connected to the motor 15, and the driving end of the motor 15 is vertically arranged upward and fixedly connected to the turntable 16. The upper side wall of the turntable 16 is rotatably connected with a connecting plate 17 at a position deviating from the center of the circle. The end of the connecting plate 17 away from the turntable 16 is rotatably connected to the end of the movable rod 20 away from the vertical tube 21. An extrusion rod 22 is fixedly connected to the upper side wall of the fixed plate 13. One end of the extrusion rod 22 is semicircular and located on the upper side of the right-angle trapezoidal plate 19. The fixed plate 11 of the metal rod 26 moves. 3 and the fixed plate 2 14, the motor 15 is started to drive the turntable 16 to rotate. When the turntable 16 drives the end of the connecting plate 17 to rotate toward the side away from the right-angled plate 18, the connecting plate 17, the movable rod 20, the vertical pipe 21 and the right-angled trapezoidal plate 19 are pulled to move toward the side of the turntable 16. At this time, the surface height of the right-angled trapezoidal plate 19 in contact with the end of the squeezing rod 22 increases, and then the squeezing rod 22 squeezes the right-angled trapezoidal plate 19 to move downward, that is, the vertical pipe 21 moves downward on the outer wall of the movable rod 20, so that the right-angled trapezoidal plate 19 moves to one side and moves downward at the same time, and contacts with the metal rod 26 after moving downward. After the contact, when the right-angled trapezoidal plate 19 moves outward, it drives the metal rod 26 to rotate through friction, so that the metal rod 26 is turned over, which avoids the metal rod 26 always contacting with the conveying roller 2 at one position, and avoids the generation of black spots.

[0020] A support rod 23 is fixedly connected to the lower side wall of the workbench 1, and a support plate 24 is fixedly connected to the end of the support rod 23. A liquid pump 25 is fixedly connected to the lower side wall of the support plate 24. A groove is provided on the upper side wall of the support plate 24, and a nozzle connected to the liquid pump 25 and arranged toward the workbench 1 is fixed in the groove. During the forward movement of the metal rod 26, the liquid pump 25 pumps external water into the nozzle and sprays it out. The sprayed water is exposed from the interval of the conveying roller 2 and contacts the metal rod 26, so as to cool the metal rod 26 and change its crystal structure. Furthermore, a nozzle can also be arranged on the upper side of the workbench 1 so that the metal rod 26 can be completely in contact with the water. The metal rod 26 continues to be conveyed forward on the workbench 1 until it falls out, and can fall into water or oil.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
