Centralized clutch drive mechanism for square tube roll forming device

Abstract

This utility model relates to a centralized clutch drive mechanism for a square tube rolling device, including a main drive, a secondary drive, a transmission system, and the square tube rolling device. The transmission system and the square tube rolling device are connected by a clutch joint. The secondary drive drives the transmission system to slide to engage or disengage from the square tube rolling device. By setting the transmission system between the main drive and the square tube rolling device, and using a telescopic universal coupling to connect the main drive and the transmission system, and using a clutch joint to connect the transmission system and the square tube rolling device, the secondary drive drives the transmission system to slide away from the square tube rolling device as a whole, thereby separating the cooperating clutch joint and the transmission system from the square tube rolling device. This allows the upper and lower rollers of the square tube rolling device to quickly disengage from the upper and lower transmission shafts, improving the convenience of overall transfer and maintenance of the square tube rolling device.

Description

Technical Field

[0001] This utility model belongs to the field of steel strip roller pressing technology, specifically relating to the centralized clutch drive mechanism of square tube roller pressing device. Background Technology

[0002] The square tube rolling mill is the main equipment used in the manufacturing process of square tubes to gradually roll and press square tubes into square tubes. It uses a drive device to drive the pressure rollers to rotate, extruding the strip steel and gradually deforming it into a square tube structure. Traditionally, the square tube rolling mill and drive device are directly connected by a universal coupling. This connection structure means that when changing the pressure rollers, the universal coupling must first be removed, and then the entire rolling mill must be lifted off the production line for maintenance. After maintenance, the rolling mill must be lifted back onto the production line, and then the universal coupling must be reinstalled. Due to the limited operating space on the production line, disassembling and assembling the universal coupling on the production line is quite difficult. Therefore, the maintenance of traditional square tube rolling mills is rather cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a centralized clutch drive mechanism for a square tube rolling device, thereby solving the technical problem of inconvenient maintenance of traditional square tube rolling devices.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a centralized clutch drive mechanism for a square tube rolling device, including a main drive, a transmission system, and a square tube rolling device. Multiple sets of the square tube rolling device are arranged sequentially. Each set of the square tube rolling device includes a pair of opposing rolling frames, a lower roller shaft, an upper roller shaft, four rolling side sliders, and four rolling side worm gear screw jacks. The upper roller shaft is parallel to the lower roller shaft directly above it. Both ends of the upper roller shaft are rotatably connected to the two rolling side sliders, and both ends of the lower roller shaft are also rotatably connected to the two rolling side sliders. The rolling side sliders at both ends of the upper and lower roller shafts are slidably connected up and down to the rolling frames. Upper and lower pressure rollers are respectively connected to the upper and lower roller shafts, facing each other. Two rolling side worm gear screw jacks... The screw jacks are mounted on the roller pressing frame above the upper roller shaft and are connected one-to-one with the roller pressing side sliders at both ends of the upper roller shaft. Two roller pressing side worm gear screw jacks are fixedly mounted below the lower roller shaft and are connected one-to-one with the roller pressing side sliders at both ends of the lower roller shaft. The four roller pressing side worm gear screw jacks are used to drive the upper and lower roller shafts to move up and down respectively. The transmission system is fixedly mounted on a base plate, which is slidably connected to a base. The base plate is connected to a secondary drive unit that drives the base plate to slide back and forth towards the square tube rolling device. The transmission system includes a transmission frame corresponding to each set of square tube rolling devices, an upper transmission shaft, a lower transmission shaft, and multiple telescopic universal couplings. The upper and lower transmission shafts are slidably connected to the transmission frame through transmission side sliders. The lower drive shafts are rotatably connected to the drive-side sliders. A drive-side worm gear screw jack is fixedly connected to the transmission frame above the upper drive shaft. This drive-side worm gear screw jack is used to drive the drive-side sliders connected to the upper drive shafts to slide up and down. A drive-side worm gear screw jack is also fixedly installed on the transmission frame below the lower drive shafts. This drive-side worm gear screw jack is used to drive the drive-side sliders connected to the lower drive shafts to slide up and down. Each drive-side worm gear screw jack on the transmission frame is connected to a lifting drive. Telescopic universal couplings are used to connect each upper drive shaft to the main drive and each lower drive shaft to the main drive. The upper drive shafts correspond one-to-one with the upper roller shafts of the square tube rolling device. The corresponding upper drive shafts and upper roller shafts are coaxially arranged, and their close ends are respectively connected to mutually matching couplings. The clutch joints are configured such that the lower drive shaft corresponds one-to-one with the lower roller shaft of the square tube rolling device. The corresponding lower drive shafts and lower roller shafts are coaxially arranged and their near ends are respectively connected to mutually cooperating clutch joints. The input shafts of the two rolling-side worm gear screw jacks located above the upper roller shaft on the same set of square tube rolling devices are coaxially arranged and connected to each other through a connecting shaft to achieve synchronous operation. The input shafts of the two rolling-side worm gear screw jacks located below the lower roller shaft are also coaxially arranged and connected to each other through a connecting shaft to achieve synchronous operation. The input axis of the rolling-side worm gear screw jack near the transmission frame on the square tube rolling device extends out of the transmission frame and is connected to a clutch joint. The input axes of the two transmission-side worm gear screw jacks on the transmission frame extend out of the corresponding square tube rolling device and are also connected to clutch joints.The corresponding upper roller shaft and upper drive shaft, with their respective drive-side worm gear screw jacks and roll-pressing-side worm gear screw jacks, achieve transmission through two clutch joints. Similarly, the corresponding lower roller shaft and lower drive shaft, with their respective drive-side worm gear screw jacks and roll-pressing-side worm gear screw jacks, also achieve transmission through two clutch joints.

[0005] As a preferred embodiment, the lifting driver is a servo motor or a stepper motor.

[0006] As a preferred embodiment, the main drive includes a main drive motor, a reducer, and multiple dual-output shaft worm gear transmission boxes connected to each other.

[0007] As a preferred embodiment, the auxiliary drive includes multiple clutch-side worm gear screw jacks connected to a base on the side of the base plate away from the square tube rolling device. The input shafts of the multiple clutch-side worm gear screw jacks are coaxially connected and driven by a clutch motor connected to the base. The output shafts of the multiple clutch-side worm gear screw jacks are connected to the base plate, driving the base plate to slide along the base. The sliding direction of the base plate is perpendicular to the arrangement direction of the square tube rolling devices. The multiple clutch-side worm gear screw jacks are arranged sequentially along the arrangement direction of the square tube rolling devices.

[0008] The beneficial effects of this utility model are as follows: By setting up a transmission system between the main drive and the square tube rolling device, and using a telescopic universal coupling to connect the main drive and the transmission system, and using a clutch joint to connect the transmission system and the square tube rolling device, the auxiliary drive drives the entire transmission system to slide away from the square tube rolling device so that the mutually cooperating clutch joints are separated, thereby separating the transmission system from the square tube rolling device. This enables the upper and lower rollers of the square tube rolling device to quickly disengage from the upper and lower transmission shafts, improving the convenience of overall transfer and maintenance of the square tube rolling device.

[0011] like Figure 1 and Figure 2 The centralized clutch drive mechanism of the square tube rolling device shown includes a main drive 1, a transmission system 2, and a square tube rolling device 3. Multiple sets of the square tube rolling device 3 are arranged sequentially. Each set of the square tube rolling device 3 includes a pair of opposing rolling frames 301, a lower roller shaft 302, an upper roller shaft 303, four rolling-side sliders 304, and four rolling-side worm gear screw jacks 305. The upper roller shaft 303 is parallel to and directly above the lower roller shaft 302. Both ends of the upper roller shaft 303 are rotatably connected to the two rolling-side sliders 304, and both ends of the lower roller shaft 302 are also rotatably connected to the two rolling-side sliders 304. The roller-side sliders 304 at each end are slidably connected to the roller frame 301. The upper roller shaft 303 and the lower roller shaft 302 are respectively connected to the upper pressure roller 306 and the lower pressure roller 307 facing each other. Two roller-side worm gear screw jacks 305 are set on the roller frame 301 above the upper roller shaft 303 and are connected to the roller-side sliders 304 at both ends of the upper roller shaft 303. Two roller-side worm gear screw jacks 305 are fixedly set below the lower roller shaft 302 and are connected to the roller-side sliders 304 at both ends of the lower roller shaft 302. The four roller-side worm gear screw jacks 305 are used to drive the upper roller shaft 303 and the lower roller shaft 302 to move up and down.

[0012] The transmission system 2 is fixedly mounted on a base plate 4, which is slidably connected to a base 5. A secondary driver 6 is connected to the base 5 to drive the base plate 4 to slide back and forth towards the square tube rolling device 3. The transmission system 2 includes a transmission frame 201 corresponding to each set of square tube rolling devices 3, an upper transmission shaft 202, a lower transmission shaft 203, and multiple telescopic universal couplings 204.

The upper transmission shaft 202 and lower transmission shaft 203 rotate with the transmission-side sliders 205. A transmission-side worm gear screw jack 206 is fixedly connected to the transmission frame 201 above the upper transmission shaft 202. The transmission-side worm gear screw jack 206 is used to drive the transmission-side slider 205 connected to the upper transmission shaft 202 to slide up and down. A transmission-side worm gear screw jack 206 is also fixedly installed on the transmission frame 201 below the lower transmission shaft 203. The transmission-side worm gear screw jack 206 is used to drive the transmission-side slider 205 connected to the lower transmission shaft 203 to slide up and down. The transmission-side worm gear screw jacks 206 on the transmission frame 201 are all connected to a lifting driver 207.

[0013] The telescopic universal coupling 204 is used to connect each upper drive shaft 202 and the main drive 1, and each lower drive shaft 203 and the main drive 1. The upper drive shaft 202 corresponds one-to-one with the upper roller shaft 303 of the square tube rolling device 3. The corresponding upper drive shaft 202 and upper roller shaft 303 are coaxially arranged and their near ends are respectively connected to mutually matching clutch joints 7. The lower drive shaft 203 corresponds one-to-one with the lower roller shaft 302 of the square tube rolling device 3. The corresponding lower drive shaft 203 and lower roller shaft 302 are coaxially arranged and their near ends are respectively connected to mutually matching clutch joints 7.

[0014] On the same set of square tube rolling device 3, the input shafts of the two rolling-side worm gear screw jacks 305 located above the upper roller shaft 303 are coaxially arranged and connected to each other via a connecting shaft 308 to achieve synchronous operation. The input shafts of the two rolling-side worm gear screw jacks 305 located below the lower roller shaft 302 are also coaxially arranged and connected to each other via a connecting shaft 308 to achieve synchronous operation. The input shaft of the rolling-side worm gear screw jack 305 on the square tube rolling device 3, which is close to the transmission frame 201, extends out of the transmission frame 201 and is connected to a clutch joint 7. The two transmission-side worm gear screw jacks 206 on the frame 201 extend from the input axis of the corresponding square tube roller pressing device 3 and are also connected to clutch joints 7; the transmission-side worm gear screw jacks 206 and roller pressing side worm gear screw jacks 305 above the upper roller shaft 303 and upper transmission shaft 202 respectively cooperate with each other to achieve transmission. The transmission-side worm gear screw jacks 206 and roller pressing side worm gear screw jacks 305 below the lower roller shaft 302 and lower transmission shaft 203 respectively cooperate with each other to achieve transmission.

[0015] In this embodiment, the lifting driver 207 is a servo motor or a stepper motor.

[0016] In this embodiment, the main drive 1 includes a main drive motor 101, a reducer 103, and multiple dual-output shaft worm gear transmission boxes 102 connected to each other. The dual-output shaft worm gear transmission boxes 102 correspond one-to-one with the transmission frame 201. Each dual-output shaft worm gear transmission box 102 has an output shaft that corresponds one-to-one with the upper transmission shaft 202 and the lower transmission shaft 203. The two output shafts of the dual-output shaft worm gear transmission box 102 are connected to the corresponding upper transmission shaft 202 and lower transmission shaft 203 through a telescopic universal coupling 204.

[0017] To ensure that the transmission system 2 and the corresponding square tube rolling device 3 are synchronously separated, the auxiliary drive 6 in this embodiment includes multiple clutch-side worm gear screw jacks 601 connected to the base 5 on the side of the base plate 4 away from the square tube rolling device 3. The input shafts of the multiple clutch-side worm gear screw jacks 601 are coaxially connected and driven by a clutch motor 602 connected to the base 5. The output shafts of the multiple clutch-side worm gear screw jacks 601 are connected to the base plate 4, driving the base plate 4 to slide along the base 5. The sliding direction of the base plate 4 is perpendicular to the arrangement direction of the square tube rolling devices 3. The multiple clutch-side worm gear screw jacks 601 are arranged sequentially along the arrangement direction of the square tube rolling devices 3.

[0018] The working process of this utility model is as follows: Figure 1 and Figure 2 As shown, when the square tube rolling device 3 is working normally, the clutch joint 7 on one side of the transmission system 2 is connected to the clutch joint 7 on the other side of the square tube rolling device 3 to realize transmission. The main drive 1 drives the upper roller shaft 303 and the lower roller shaft 302 to rotate through each telescopic universal coupling 204, the upper transmission shaft 202, the lower transmission shaft 203 and the clutch joint 7, which in turn drives the upper pressure roller 306 and the lower pressure roller 307 to rotate and extrude the strip steel or square tube. When the upper pressure roller 306 and lower pressure roller 307 of the square tube rolling device 3 need to be replaced, the clutch motor 602 of the auxiliary drive 6 drives the clutch-side worm gear screw jack 601 to rotate synchronously. The clutch-side worm gear screw jack 601 drives the floor 4 to the square tube rolling device 3, the interconnected clutch joints 7 separate, the telescopic universal coupling 204 retracts, and the square tube rolling device 3, which is disconnected from the transmission system 2, is removed from the production line and hoisted to the maintenance point for pressure roller replacement. After the replacement is completed, the square tube rolling device 3 is hoisted back to the production line, and the auxiliary drive 6 drives the transmission system 2 to move toward the square tube rolling device 3, so that the corresponding clutch joints 7 are reconnected, and the main drive 1 can then drive the square tube rolling device 3 to work again.

[0019] Since the transmission-side worm gear screw jack 206 is used to position the transmission-side slider 205 connected to the upper transmission shaft 202, the position of the upper transmission shaft 202 remains unchanged after the transmission system 2 is disengaged from the square tube rolling device 3, thereby achieving rapid docking with the rolling-side worm gear screw jack 305 on the square tube rolling device 3.

[0020] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
