Description

Technical Field

[0001] This invention relates to the field of copper tube cold rolling technology, and in particular to a rotary feeding control system for a cold rolling mill. Background Technology

[0002] During cold rolling of copper tubes, a feeding system is required to drive the tubes into the cold rolling mill. Specifically, the feeding system includes a sliding block, a support assembly located above the sliding block for pushing the copper tube, and a drive device for driving the sliding block's reciprocating motion. When feeding the copper tube, the feeding system places the tube to be cold rolled in front of the support assembly. Then, the drive device drives the sliding block towards the cold rolling mill, and the support assembly pushes the copper tube towards the mill. The copper tube slowly enters the cold rolling mill for cold rolling. After cold rolling, the drive device drives the sliding block away from the cold rolling mill, and the sliding block returns to its initial position, ready to push the next copper tube for cold rolling. Due to the large length of the copper tube, the existing sliding block has a very large stroke, resulting in a slow return speed and consequently a reduction in the cold rolling speed. Summary of the Invention

[0003] To address the shortcomings of existing feeding systems, which have long sliding block travel and thus low cold rolling speed, this invention proposes a rotary feeding control system for cold rolling mills that reduces the sliding block travel and thereby increases the cold rolling speed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotary feeding control system for a cold rolling mill includes a base, a sliding seat slidably connected to the upper side of the base, and a drive box fixedly connected to one end of the base. A servo motor is mounted on one side of the drive box, and the servo motor is connected to a worm gear. One end of the worm gear is located inside the drive box and is fitted with a turbine. The turbine is fixedly connected to a lead screw, which passes through the sliding seat and is threadedly connected to the sliding seat. A support assembly for pushing a copper tube is mounted on the upper side of the sliding seat. The sliding seat includes a main body slidably connected to the base, a groove on the upper side of the main body, a connecting seat slidably connected to the groove, and the connecting seat is connected to the right end of the groove via a second spring. The sliding seat also includes a rotatably connected to the main body... The system includes a first bevel gear on the side of the drive box, a connecting plate fixedly connected to the main body, a second bevel gear engaging with the upper side of the first bevel gear, a rotating shaft fixedly connected to the upper side of the second bevel gear, a gear fixedly connected to the upper end of the rotating shaft, an electric cylinder mounted on the upper side of the gear, a support assembly mounted on a connecting seat, a clearance groove on the main body, a lead screw passing through the clearance groove and the first bevel gear, the first bevel gear and the lead screw being threaded together, a rotating shaft passing through the connecting plate and slidingly connected to the connecting plate, an electric cylinder connected to the connecting plate via a bracket, an output shaft of the electric cylinder axially downwards and rotatingly connected to the gear, and a rack fixedly connected to the side of the connecting seat near the drive box, the rack meshing with the gear.

[0006] With the above settings, when the main body pushes the copper tube, the connecting seat continues to push the copper tube to the right in place of the main body. This reduces the movement stroke of the main body without affecting the pushing distance of the copper tube, thereby speeding up the return speed of the main body. While the main body returns to its original position, the connecting seat moves to the left along the slide. When the main body returns to its initial position, the connecting seat returns to the left end of the slide.

[0007] Furthermore, the first bevel gear includes a gear section and a damping section, the gear section and the second bevel gear are engaged, a damping groove adapted to the damping section is provided on one side of the main body, the damping section is disposed in the damping groove and is interference-fitted with the damping groove, the lead screw passes through the damping section and the gear section, and both the damping section and the gear section are threadedly connected to the lead screw.

[0008] Furthermore, the support assembly includes two support rods, which are arranged sequentially along the width direction of the base and extend along the width direction of the base. The end of one support rod away from the other support rod is rotatably connected to the base, and the end of the support rod near the other support rod is rotatably connected to a roller. The roller is located on the side of the support rod near the drive box. An elastic element is provided on one side of the support rod, with one end of the elastic element connected to the base and the other end of the elastic element connected to the support rod. A guide rod is provided above the base, extending along the length direction of the base, and the guide rod is located between the support rods.

[0009] Furthermore, the end of the support rod away from the other support rod is rotatably connected to the connecting seat, and the end of the elastic element away from the support rod is connected to the connecting seat.

[0010] Furthermore, an elastic element is disposed on the side of the support rod near the drive box. The elastic element includes a sleeve and a sliding block slidably connected inside the sleeve. The bottom of the sleeve is rotatably connected to the base. A first spring is disposed inside the sleeve. One end of the first spring is connected to the bottom of the sleeve, and the other end of the first spring is connected to the sliding block. A connecting rod is fixedly connected to the side of the sliding block away from the first spring. A protrusion is fixedly connected to the end of the connecting rod away from the sliding block. An ear plate is fixedly connected to one side of the support rod. The ear plate is provided with an elongated hole, and the protrusion is disposed inside the elongated hole.

[0011] Furthermore, the worm gear is located on the underside of the turbine.

[0012] Furthermore, there are two turbines, each of which is fixedly connected to a lead screw. The lead screw passes through both ends of the sliding seat and is threadedly connected to the sliding seat.

[0013] Furthermore, a support plate is fixedly connected to the end of the base away from the drive box, and the support plate and the lead screw are rotatably connected. Attached Figure Description

[0024] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] See Figures 1 to 10 A rotary feeding control system for a cold rolling mill includes a base 11, a sliding seat 12 slidably connected to the upper side of the base 11, and a drive box 13 fixedly connected to one end of the base 11. A servo motor 131 is provided on one side of the drive box 13. The servo motor 131 is connected to a worm gear 132. One end of the worm gear 132 is located inside the drive box 13 and is fitted with a turbine 133. The turbine 133 is fixedly connected to a lead screw 134. The lead screw 134 passes through the sliding seat 12 and is threadedly connected to the sliding seat 12. A support assembly 14 for pushing a copper tube 21 is provided on the upper side of the sliding seat 12.

[0026] With the above configuration, this application features fast response speed and high precision. Specifically, during cold rolling, the feeding system transports the copper tube 21 to the right side of the support assembly 14. Then, the servo motor 131 drives the lead screw 134 to rotate via the worm gear 132 and turbine 133. After the lead screw 134 and the sliding seat 12 rotate relative to each other, the sliding seat 12 moves to the right along the axis of the lead screw 134 on the base 11. The support assembly 14 pushes the copper tube 21 to the right, allowing it to enter the cold rolling mill for cold rolling. When the sliding seat 12 reaches the right end of the base 11, the servo motor 131 rotates in the opposite direction, causing the sliding seat 12 to move to the left and return to its initial position. Then, the feeding system places the next copper tube 21 on the right side of the support assembly 14, and the above steps are repeated to continue cold rolling. This application uses a servo motor 131 to drive the sliding seat 12. Compared with traditional DC motors, the servo motor 131 has a faster response speed and higher precision, thereby improving the speed and stability of cold rolling.

[0027] In one implementation, the support assembly 14 includes two support rods 141, which are arranged sequentially along the width direction of the base 11 and extend along the width direction of the base 11. The end of the support rod 141 away from the other support rod 141 is rotatably connected to the base 11, and the end of the support rod 141 near the other support rod 141 is rotatably connected to a roller 142. The roller 142 is located on the side of the support rod 141 near the drive box 13. An elastic element 143 is provided on one side of the support rod 141. One end of the elastic element 143 is connected to the base 11, and the other end of the elastic element 143 is connected to the support rod 141. A guide rod 15 is provided above the base 11 and extends along the length direction of the base 11. The guide rod 15 is located between the support rods 141.

[0028] Through the above settings, the copper tube 21 is pushed. Specifically, the existing feeding system pushes the copper tube 21 to the cold rolling mill through a pusher tube 22. Initially, the copper tube 21 and the pusher tube 22 are located to the left of the guide rod 15. Then, the pusher tube 22 pushes the copper tube 21 to the right. The copper tube 21 and the pusher tube 22 are fitted onto the guide rod 15 and move to the right along the guide rod 15. After the right end of the copper tube 21 moves to the support rod 141, it pushes the support rod 141 to rotate, and the elastic element 143 deforms. When the copper tube 21 moves to the right side of the support rod 141, the right end of the pusher tube 22 moves to the right side of the support rod 141. See [link to relevant documentation]. Figure 5 At this point, roller 142 abuts against push tube 22, and then push tube 22 begins to move to the left, returning to its initial position and disengaging from guide rod 15. During this process, roller 142 rotates, thereby reducing the resistance to the leftward movement of push tube 22. When push tube 22 and roller 142 disengage, under the action of elastic element 143, support rod 141 rotates and returns to its initial position. See [link to relevant documentation]. Figure 6Then, the servo motor 131 moves and drives the sliding seat 12 to move to the right. The support rod 141 pushes the copper tube 21 to move to the right and causes the copper tube 21 to enter the cold rolling mill for cold rolling. When the sliding seat 12 moves to the right end of the base 11, the sliding seat 12 moves back to the left end of the base 11 under the action of the servo motor 131 and is ready to receive the next copper tube 21.

[0029] In one implementation, the elastic element 143 is disposed on the side of the support rod 141 near the drive box 13. The elastic element 143 includes a sleeve 1431 and a sliding block 1432 slidably connected inside the sleeve 1431. The bottom of the sleeve 1431 is rotatably connected to the base 11. A first spring 1433 is disposed inside the sleeve 1431. One end of the first spring 1433 is connected to the bottom of the sleeve 1431, and the other end of the first spring 1433 is connected to the sliding block 1432. A connecting rod 1434 is fixedly connected to the side of the sliding block 1432 away from the first spring 1433. A protrusion 1435 is fixedly connected to the end of the connecting rod 1434 away from the sliding block 1432. An ear plate 1411 is fixedly connected to one side of the support rod 141. The ear plate 1411 is provided with an elongated hole 1412, and the protrusion 1435 is disposed inside the elongated hole 1412.

[0030] With the above configuration, when the support rod 141 is pushed and rotated by the copper tube 21, the first spring 1433 lengthens, the sliding block 1432 moves along the sleeve 1431, the protrusion 1435 moves along the elongated hole 1412, and the connecting rod 1434 is connected to the support rod 141 via the protrusion 1435, the ear plate 1411, and the support rod 141. When the push tube 22 moves away from between the support rods 141, the first spring 1433 shortens, and the support rod 141 returns to its initial position.

[0031] As one implementation, the worm gear 132 is located on the underside of the turbine 133.

[0032] In one implementation, there are two turbines 133, each of which is fixedly connected to a lead screw 134. The lead screw 134 passes through both ends of the sliding seat 12 and is threadedly connected to the sliding seat 12.

[0033] As one implementation, a support plate 111 is fixedly connected to the end of the base 11 away from the drive box 13, and the support plate 111 and the lead screw 134 are rotatably connected.

[0034] In one implementation, the sliding seat 12 includes a main body 121 slidably connected to the base 11, a slide groove 122 disposed on the upper side of the main body 121, a connecting seat 123 slidably connected in the slide groove 122, and the connecting seat 123 being connected to the right end of the slide groove 122 via a second spring 124. The sliding seat 12 also includes a first umbrella 125 rotatably connected to the side of the main body 121 near the drive box 13, a connecting plate 126 fixedly connected to the main body 121, a second bevel gear 1251 cooperating with the upper side of the first umbrella 125, a rotating shaft 1252 fixedly connected to the upper side of the second bevel gear 1251, and a gear fixedly connected to the upper end of the rotating shaft 1252. The gear 1253 is a wheel 1253, an electric cylinder 1254 is set on the upper side of the gear 1253, a support assembly 14 is set on the connecting seat 123, the main body 121 is provided with a clearance groove 1211, the lead screw 134 passes through the clearance groove 1211 and the first umbrella 125, the first umbrella 125 and the lead screw 134 are threadedly connected, the rotating shaft 1252 passes through the connecting plate 126 and is slidably connected to the connecting plate 126, the electric cylinder 1254 is connected to the connecting plate 126 through the bracket, the output shaft of the electric cylinder 1254 is axially downward and rotatably connected to the gear 1253, and a rack 1231 is fixedly connected to the side of the connecting seat 123 near the drive box 13, the rack 1231 and the gear 1253 mesh.

[0035] The first umbrella 125 includes a gear part 1255 and a damping part 1256. The gear part 1255 and the second bevel gear 1251 are engaged. A damping groove 1212 adapted to the damping part 1256 is provided on one side of the main body 121. The damping part 1256 is disposed in the damping groove 1212 and is interference-fitted with the damping groove 1212. The lead screw 134 passes through the damping part 1256 and the gear part 1255. Both the damping part 1256 and the gear part 1255 are threadedly connected to the lead screw 134.

[0036] The end of the support rod away from the other support rod is rotatably connected to the connecting seat, and the end of the elastic element away from the support rod is connected to the connecting seat.

[0037] By adjusting the above settings, the travel distance of the sliding block 12 is reduced, thereby accelerating its return speed and consequently increasing the cold rolling speed of the copper tube 21. For details, see... Figure 1 Initially, the connecting seat 123 is located at the left end of the slide 122. When the pusher tube 22 pushes the copper tube 21 to the right and causes the copper tube 21 to move to the right side of the support rod 141, the copper tube 21 pushes the support rod 141 to rotate until the right end of the pusher tube 22 moves to the right side of the support rod 141. See [link to relevant documentation]. Figure 5 At this time, roller 142 rests against push tube 22, push tube 22 moves to the left and moves away from support rod 141. Under the action of elastic element 143, support rod 141 rotates back to its initial position. See [link to relevant documentation]. Figure 6The servo motor 131 operates and drives the lead screw 134 to rotate via the worm gear 132 and the turbine 133. Due to the interference fit between the damping part 1256 and the damping groove 1212, when the lead screw 134 rotates, the lead screw 134 and the first umbrella 125 rotate relative to each other. The lead screw 134 drives the main body 121, the support rod 141, and the copper tube 21 to move to the right through the first umbrella 125. (See also...) Figure 7 At this point, the torque applied by the lead screw 134 to the first umbrella 125 is relatively small, and the damping part 1256 and the damping groove 1212 are relatively fixed. However, when the main body 121 moves to the point where the support plate 111 can no longer move to the right, that is, when the first umbrella 125 can no longer move to the right, the torque of the lead screw 134 on the first umbrella 125 increases. The torque overcomes the friction between the damping part 1256 and the damping groove 1212, driving the damping part 1256 to rotate within the damping groove 1212. (See [reference]) Figure 8 The damping part 1256 drives the connecting seat 123 to move to the right via the gear part 1255, the second bevel gear 1251, the rotating shaft 1252, the gear 1253, and the rack 1231. The elastic element 143 and the support rod 141 are both mounted on the connecting seat 123. Therefore, the support rod 141 will continue to drive the copper tube 21 to move to the right for cold rolling. (See [reference]) Figure 9 The second spring 124 shortens. When the connecting seat 123 moves to the right end of the slide groove 122, the electric cylinder 1254 drives the gear 1253 to move upward through the output shaft. Since the rack 1231 extends horizontally, when the gear 1253 moves upward, the gear 1253 and the rack 1231 disengage. At the same time, the gear part 1255 and the second bevel gear 1251 disengage. Under the action of the second spring 124, the connecting seat 123 moves along the slide groove 122 to the left end of the slide groove 122. During this process, the servo motor 131 drives the lead screw 134 to rotate in the opposite direction. The main body 121 and the first umbrella 125 move to the left on the base 11, that is, the main body 121 and the first umbrella 125 move to the initial position. At this time, the torque of the lead screw 134 on the first umbrella 125 is relatively small, and the damping part 1256 and the damping groove 1212 are relatively fixed. See Figure 10 When the main body 121 returns to its initial position, the electric cylinder 1254 drives the gear 1253 to move downwards, and the gear 1253 re-engages with the gear 1253. At the same time, the gear part 1255 re-engages with the second bevel gear 1251. (See below) Figure 1 and Figure 4 The next copper tube 21 can continue to be cold rolled. In this application, when the main body 121 pushes the copper tube 21, the connecting seat 123 replaces the main body 121 to continue pushing the copper tube 21 to the right. While not affecting the pushing distance of the copper tube 21, the movement stroke of the main body 121 is reduced, thereby speeding up the return speed of the main body 121. While the main body 121 returns to its original position, the connecting seat 123 moves to the left along the slide groove 122. When the main body 121 returns to its initial position, the connecting seat 123 returns to the left end of the slide groove 122.
