Description

Technical Field

[0001] The invention relates to the technical field of shielding tube processing, in particular to a shielding tube rib rolling device and a processing technology thereof. Background Art

[0002] When the metal bellows is used in the vacuum switch cabinet, the shielding tube needs to be placed outside the metal bellows to provide shielding protection for the metal bellows. In order to connect the shielding tube with the mounting components, ribs need to be provided on the surface of the shielding tube, and the shielding tube and the mounting components of the vacuum switch cabinet are embedded through the ribs.

[0003] When the equipment in the prior art rolls the shielding tube, it is necessary to sleeve the shielding tube on the rolling column, and then the rolling wheel presses the shielding tube against the rolling column from the side. The rotation of the rolling column drives the shielding tube and the rolling wheel to rotate through friction to complete the rolling of the side of the shielding tube. In this process, a rotatable pressure plate coaxial with the rolling column is also required to press the shielding tube against the rolling column to prevent the shielding tube from shifting in position during the rolling process. However, since the inner diameter of the shielding tube is larger than the outer diameter of the rolling column, during the rolling process, one side of the inner surface of the shielding tube is in close contact with the rolling column, and there is a large gap between the other side and the rolling column. The rotation of the shielding tube is not coaxial with the rotation of the pressure plate, which causes the contact surface of the shielding tube and the pressure plate to be relatively displaced and generate dynamic friction. If the pressure of the pressure plate on the shielding tube is insufficient, the position of the shielding tube may be shifted during rolling. If the pressure is too large, the friction between the shielding tube and the pressure plate may be too large, causing greater wear on both, and at the same time, it brings greater resistance to the operation of the power source for rotating the rolling column, resulting in a waste of power resources. Summary of the invention

[0004] In order to solve the problem of mutual wear caused by the non-coaxial rotation of the pressure plate and the shielding cylinder during the shielding cylinder bead rolling process, the present invention provides a shielding cylinder bead rolling equipment and a processing technology thereof.

[0005] In the first aspect, the present invention provides a shielding tube bead rolling device, a shielding tube bead rolling device includes a base, a control mechanism, a limit pressure plate, a shielding tube and a bead rolling mechanism, the bead rolling mechanism includes a motor, a support plate, a bead rolling shaft and an upper bead rolling assembly, the motor and the support plate are fixedly arranged on the base, the output shaft of the motor passes through the support plate and is rotatably connected to the support plate, the bead rolling shaft is keyed to the output shaft of the motor, the shielding tube is sleeved on the bead rolling shaft, the upper bead rolling assembly is used for cooperating with the bead rolling shaft to roll the shielding tube, a plurality of universal ball discs are fixedly arranged on a side of the limit pressure plate close to the shielding tube, and the control mechanism is used for controlling the movement of the limit pressure plate to press the shielding tube against the bead rolling shaft when the bead rolling mechanism rolls the shielding tube.

[0006] From the above, it can be seen that when the shielding tube is rolled, the limit pressure plate presses the bottom of the shielding tube onto the rolling shaft through the universal ball disc, and then the upper rolling assembly presses the side of the shielding tube onto the rolling shaft. The output shaft of the motor drives the rolling shaft to rotate, and the rolling shaft drives the shielding tube to rotate through static friction. When the shielding tube rotates, it drives the balls on the universal ball disc to rotate through friction. The balls can maintain pressure on the shielding tube during the rolling process and only bring very small resistance to the rotation of the shielding tube. While ensuring that the position of the shielding tube is not offset, the mutual wear caused by direct contact between the limit pressure plate and the shielding tube is avoided.

A connecting bolt 8 is threadedly connected in the second threaded hole 73. One end of the connecting bolt 8 is threadedly connected in the first threaded hole 71 provided on the roller shaft 53.

[0024] As can be seen from the above, before the equipment is put into operation, the staff can sleeve the shielding cylinder 4 that needs to be rolled on the rolling shaft 53 and make the bottom of the shielding cylinder 4 contact with the bottom surface of the adjusting disk 7, and then start the equipment, the second electric push cylinder 21 pushes the sliding plate 23 to slide on the slide rail 22, the limit pressure plate 3, the universal ball plate 31 and the stripping strip 63 approach the shielding cylinder 4, and the arc surface 631 on the stripping strip 63 will first contact the edge of the bottom of the shielding cylinder 4. Since the inner diameter of the shielding cylinder 4 is larger than the outer diameter of the rolling strip 531, when the shielding cylinder 4 is naturally placed on the rolling shaft 53, the shielding cylinder 4 The top of the inner circumference is in contact with the ribbed strip 531, while the bottom keeps a certain distance from the ribbed shaft 53 and the ribbed strip 531; as the stripping strip 63 continues to move, the vertical force exerted by the arc surface 631 on the edge of the shielding tube 4 pushes the end of the shielding tube 4 in contact with the arc surface 631 to move upward until the stripping strip 63 moves to the bottom of the shielding tube 4, and the top of the stripping strip 63 is in contact with the outer circumference of the shielding tube 4, and then the stripping strip 63 continues to move and passes under the shielding tube 4 until it is no longer in contact with the shielding tube 4, at which time the shielding tube 4 returns to its initial position under the action of gravity; When the balls on the universal ball disc 31 come into contact with the shielding cylinder 4, the shielding cylinder 4 blocks the movement of the limit pressure plate 3 and the connecting shaft 254, and the output shaft of the second electric push cylinder 21 pushes the sliding plate 23 and the first housing 24 to continue to move a certain distance. During this process, the piston 253 slides relative to the spring groove 241 toward the direction close to the limit shaft 251, and the spring 252 is compressed under the action of the limit shaft 251 and the piston 253. The spring 252 applies pressure to the connecting shaft 254 to make the universal ball disc 31 press the shielding cylinder 4, thereby The cylinder 4 is pressed against the adjusting disk 7; then the output shaft of the first electric push cylinder 542 pushes the sliding support plate 544 downward, and the sliding support plate 544 drives the rib wheel 545 downward until the rib wheel 545 contacts the side of the shield cylinder 4 and presses the shield cylinder 4, at which time the inner circumference of the shield cylinder 4 abuts against the rib strip 531; the output shaft of the motor 51 drives the rib shaft 53 to rotate, and the rib strip 531 drives the shield cylinder 4 to rotate through friction, and similarly the shield cylinder 4 drives the rib wheel 545 to rotate, and then the first electric push cylinder 542 continues to slide The support plate 544 applies pressure, and the sliding support plate 544 causes the rib wheel 545 to continue to apply pressure to the side of the shielding cylinder 4. The side of the shielding cylinder 4 begins to deform under the action of the rib strip 531. As the shielding cylinder 4 continues to rotate, the rib strip 531 and the rib groove 5451 press the side of the shielding cylinder 4 into annular ribs. In this process, since the shielding cylinder 4 rotates and drives the balls on the universal ball disk 31 to rotate through friction, the balls can maintain pressure on the shielding cylinder 4 during the rolling process and only cause the shielding cylinder 4 to rotate. The resistance is very small, and the mutual wear caused by the direct contact between the limit pressure plate 3 and the shielding cylinder 4 is avoided while ensuring that the position of the shielding cylinder 4 does not shift; the buffer component 25 can play a buffering role when the universal ball disc 31 contacts the shielding cylinder 4, so that the pressure applied by the universal ball disc 31 to the shielding cylinder 4 gradually increases, and at the same time, the second electric push cylinder 21 can be allowed to have a certain error in the position control of the universal ball disc 31, so as to avoid direct collision without buffering when the universal ball disc 31 contacts the shielding cylinder 4, causing damage to certain parts of the equipment; After completing the rib rolling of the shielding cylinder 4, the second electric push cylinder 21 drives the sliding plate 23 to move, and the limiting pressure plate 3 and the universal ball disk 31 gradually move away from the shielding cylinder 4, and at the same time the material stripping strip 63 starts to move back. Since the top of the material stripping strip 63 is higher than the lowest point on the side of the shielding cylinder 4, after the material stripping strip 63 contacts the shielding cylinder 4, it drives the shielding cylinder 4 to move away from the motor 51. When the shielding cylinder 4 is completely separated from the adjusting disk 7, the shielding cylinder 4 passes through the material stripping port 11 under the action of gravity and falls to the bottom of the base 1. The staff can collect the shielding cylinder 4 that has completed the rib rolling operation by setting a material collecting facility under the material stripping port 11, and the staff no longer needs to manually remove the shielding cylinder 4 from the rib rolling shaft 53, which can improve the working efficiency of the equipment and reduce the safety hazards when the equipment is working; when producing shielding cylinders 4 with a larger outer diameter, the height of the lowest point on the side of the shielding cylinder 4 will be different. When the stripping strip 63 contacts the shielding tube 4, it cannot push the shielding tube 4 upward, which causes the stripping strip 63 to be unable to move further. The staff can adjust the height of the stripping strip 63 according to the shielding tube 4 of different specifications, and turn the second screw rod 641 by the handle 6411. The second screw rod 641 drives the limiting plate 642 to rotate inside the stripping strip 63. The threaded hole pushes the second screw rod 641 and the limiting plate 642 to move. The limiting plate 642 drives the stripping strip 63 to slide up and down inside the second slide groove 621, so that the height of the stripping strip 63 can be adjusted so that the top of the stripping strip 63 is slightly higher than the lowest point of the side of the shielding tube 4 and lower than the lowest point of the rolling strip 531, thereby ensuring that the stripping strip 63 can be smoothly moved to the farthest end and complete the subsequent automatic stripping operation, thereby improving the practicability of the equipment. If the elastic force applied by the spring 252 to the piston 253 is too large during the rolling process, the universal ball disc 31 may apply too much pressure to the shielding cylinder 4. Since the shielding cylinder 4 and the adjusting disk 7 do not rotate coaxially, the excessive pressure between the shielding cylinder 4 and the adjusting disk 7 may cause the shielding cylinder 4 to rotate poorly or be unable to rotate. Excessive pressure may also accelerate the wear inside the universal ball disc 31. At this time, the staff can turn the first screw rod 261 through the hand wheel 2611 when the equipment stops running. The first screw rod 261 is pushed by the threaded hole connected to the first housing 24 to pull the limit The limiting plate 262 slides inside the first slide groove 242, and the limiting plate 262 drives each limiting shaft 251 away from the piston 253. The spring 252 is extended to reduce the pressure of the spring 252 on the piston 253, which also reduces the pressure of the universal ball plate 31 on the shielding cylinder 4 when the first housing 24 moves the same distance, thereby avoiding the shielding cylinder 4 from rotating smoothly. Similarly, when the elastic force of the spring 252 is too small and the universal ball plate 31 cannot effectively limit the position of the shielding cylinder 4 from shifting, the first screw rod 261 can be twisted in the opposite direction to increase the elastic force of the spring 252. The staff can change the position of the ribs on the side of the shielding tube 4 by reducing or adding adjusting disks 7. For example, when the rib position needs to be moved away from the bottom surface of the shielding tube 4, the staff can add adjusting disks 7 of a certain thickness and quantity; when the equipment is shut down, take out the adjusting disk 7 that needs to be added, and then insert the pin 74 on the adjusting disk 7 into the socket on the installed adjusting disk 7, and at the same time, align the two second threaded holes 73 on the adjusting disk 7 with the two first threaded holes 71 on the installed adjusting disk 7, and then fix the adjusting disk 7 on the installed adjusting disk 7 by connecting bolts 8; after the adjustment work is completed, the shielding tube 4 is sleeved on the rib shaft 53 and the adjusting disk 7. When the bottom of the shielding tube 4 is pressed onto the adjusting disk 7, the contact point between the inner circumference of the shielding tube 4 and the rib strip 531 is changed, thereby completing the adjustment of the rib position, improving the practicability of the equipment, and simplifying the complexity of the equipment relative to the method of adjusting the position of the rib shaft 53 and the rib wheel 545.

[0025] Embodiment 2: The embodiment of the present application also provides a processing technology of a shielding tube 4 rib rolling device, and the processing technology of a shielding tube 4 rib rolling device includes the following steps: S1: Sleeve the shielding tube 4 on the rib rolling shaft 53 and make the inner bottom surface of the shielding tube 4 contact with the adjustment disk 7, then start the equipment, the second electric push cylinder 21 controls the limit pressure plate 3 to move so that the universal ball plate 31 contacts with the outer bottom surface of the shielding tube 4 to press the shielding tube 4 on the adjustment disk 7, the first electric push cylinder 542 pushes the sliding support plate 544 downward to make the rib rolling wheel 545 contact with the shielding tube 4, the rib rolling wheel 545 presses the side of the shielding tube 4 on the rib rolling shaft 53, the motor 51 rotates to drive the rib rolling shaft 53, the shielding tube 4 and the rib rolling wheel 545 to rotate to perform the rib rolling operation on the shielding tube 4; S2: After the bar rolling operation is completed, the motor 51 stops, the first electric push cylinder 542 controls the bar rolling wheel 545 to move away from the shielding cylinder 4, and the second electric push cylinder 21 controls the universal ball disc 31 to move away from the shielding cylinder 4. After the stripping strip 63 contacts the shielding cylinder 4, it gradually pushes the shielding cylinder 4 away from the bar rolling shaft 53 until the shielding cylinder 4 falls off the bar rolling shaft 53 and the adjustment disk 7. The shielding cylinder 4 that has completed bar rolling falls from the stripping port 11 to the bottom of the base 1. The staff can collect the shielding cylinder 4 that has completed bar rolling from the stripping port 11.
