Description

Technical Field

[0001] The present invention relates to the field of conveying technology, 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 metal bar processing workshops, after quenching the metal bars, the high-temperature metal bars often need to be water-cooled and then conveyed to other process equipment via rollers for further processing. Traditional conveyor rollers can only move the metal bars forward during the conveying process, but cannot rotate the metal bars during the forward movement, thereby avoiding contact with the rollers at one position all the time, resulting in accumulation of metal bars, overheating, and producing black spots.

[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 object, the present invention adopts the following technical solution: a metal rod conveying device, comprising a workbench, a mounting groove is formed 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;

[0007] The top end face of said sliding panel also is provided with an interlocking structure, and the interlocking structures are pivotally connected to each other with a set of movable lids being placed on the interlocking structures.

[0008] In the above-mentioned metal rod conveying device, the pushing mechanism includes a center plate 1 and a center plate 2 symmetrically fixed on the side walls of the workbench, a push plate is slidably inserted in the middle of the center plate 1, a through opening is opened in the middle of the center plate 2, a rotating plate is provided in the through opening, a motor is fixed to the upper side wall of the center plate 2, the driving end of the motor passes through the upper side wall of the center plate 2 and is fixedly connected to the rotating plate, the end of the rotating plate is fixedly connected to a pillar, the upper end of the pillar is fixedly connected to a connecting rod, the upper side wall of the center plate 1 is fixedly connected to a guide frame, a movable frame is slidably inserted in the guide frame, the end of the movable frame is located on the outside of the push plate, and the other end of the movable frame is rotatably connected to the end of the connecting rod away from the pillar.

[0009] 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.

[0010] 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.

[0011] In the above-mentioned metal rod conveying device, a gap is provided between the fixed plate 1 and the second end of the fixed plate, and the size of the gap is equal to the minimum distance between the center plate 1 and the second end of the center plate.

[0012] 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 fixed plate and the second fixed plate.

[0013] In the above-mentioned metal rod conveying device, the motor is a stepping motor.

[0014] Compared with the existing technology, the advantages of this metal rod conveying device are:

[0015] 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 toward the center line of the workbench, pushing the other end of the metal rod 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.

[0016] 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-angled plate, the connecting plate, the movable rod, the vertical tube and the right-angled trapezoidal plate are pulled toward the turntable. At this time, the surface height of the right-angled trapezoidal plate in contact with the end of the extrusion rod rises, and then the extrusion rod squeezes the right-angled trapezoidal plate to move downward, that is, the vertical tube moves downward on the outer wall of the movable rod, so that the right-angled trapezoidal plate moves to one side and moves downward at the same time, and contacts the metal rod after moving downward. After contact, when the right-angled trapezoidal plate moves outward, it drives the metal rod to rotate through friction, so that the metal rod is flipped, thereby preventing the metal rod from always contacting the conveying roller at one position, and avoiding the generation of black spots.

[0017] 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-angled 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

[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Reference Figure 1-Figure 3The lifting mechanism of the lifting mechanism comprises a lifting mechanism, a lifting mechanism of the lifting mechanism, a lifting mechanism of the lifting mechanism and a lowering mechanism, wherein the lifting mechanism comprises a lifting mechanism of the lifting mechanism, a lifting mechanism of the lifting mechanism and a lowering mechanism, wherein the lifting mechanism comprises a lifting mechanism, a lifting mechanism, a lifting mechanism and a lowering mechanism, wherein the lifting mechanism comprises a lifting mechanism, a lifting mechanism, a lifting mechanism, a lifting mechanism and a lowering mechanism, wherein the lifting mechanism comprises a lifting mechanism, a lifting mechanism, a lifting mechanism, a lifting mechanism, a lifting mechanism

[0024] 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 the pillar 9, and the upper end of the pillar 9 is fixedly connected to the connecting rod 10. The upper side wall of the center plate 3 is fixedly connected to the guide frame 11. A movable frame 12 is slidably inserted in the guide frame 11. The end of the movable frame 12 is located on the outer side of the push plate 4. The other end of the movable frame 12 is rotatably connected to the end of the connecting rod 10 away from the pillar 9. The push plate 4 is away from the fixed plate 13 and the fixed plate 2. The outer wall of the end 14 has an inclined surface 7. The setting of the inclined surface 7 has a diversion effect on the metal rod 26. The quenched metal rod 26 is placed on the workbench 1 and is driven by the rotation of the conveying roller 2 to transport the metal rod 26 forward. 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 pass smoothly between the fixed plate 13 and the fixed plate 2.

[0025] 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 pushing plate 4 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 transformed from a messy state to a state consistent with the center line of the workbench 1, and then conveyed forward. At the same time, it avoids 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;

[0026] The flipping mechanism includes a fixed plate 13 and a fixed plate 2 14 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, and 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. There is a gap between the ends of the fixed plate 13 and the fixed plate 2 14, and 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, and 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.

[0027] A right-angled plate 18 is fixedly connected to the fixed plate 2 14, and a right-angled trapezoidal plate 19 is slidably sleeved on the end of the right-angled plate 18. The upper side wall of the right-angled trapezoidal plate 19 is fixedly connected to a vertical tube 21, 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 2 14 away from the fixed plate 1 13 is fixedly connected to the motor 15. The driving end of the motor 15 is vertically upwardly arranged and fixedly connected to the turntable 16. The upper side wall of the turntable 16 is rotatably connected to the 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. The upper side wall of the fixed plate 13 is fixedly connected to an extrusion rod 22. One end of the extrusion rod 22 is semicircular and located on the upper side of the right-angled trapezoidal plate 19. The fixed plate 1 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 to the side away from the right-angled plate 18, the connecting plate 17, the movable rod 20, the vertical tube 21 and the right-angled trapezoidal plate 19 are pulled to 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 extrusion rod 22 increases, and then the extrusion rod 22 will squeeze the right-angled trapezoidal plate 19 to move downward, that is, the vertical tube 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 the metal rod 26 after moving downward. After contact, when the right-angled trapezoidal plate 19 moves outward, it will drive the metal rod 26 to rotate by friction, so that the metal rod 26 is flipped, avoiding the metal rod 26 always contacting the conveying roller 2 at one position, avoiding the generation of black spots.

[0028] 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 gap between the conveying rollers 2 and contacts the metal rod 26, cooling the metal rod 26 and changing its crystal structure. Furthermore, a nozzle can also be provided 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 may fall into water or oil.

[0029] 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 principles of the present invention should be included in the scope of protection of the present invention.
