Description

Technical Field

[0001] The invention relates to the technical field of stainless steel welded pipe roller deformation correction, and more specifically, to a stainless steel welded pipe roller deformation correction device and a correction process thereof. Background Art

[0002] Stainless steel welded pipe rollers are key components used in the production of stainless steel welded pipes. In the production of stainless steel welded pipes, the rollers continuously extrude and deform the steel strips to gradually form a tubular structure. When the rollers are worn, deformed or damaged, they should be repaired or replaced in time to ensure the production quality of the welded pipes.

[0003] At present, when the roller is damaged during the processing of stainless steel pipes, mechanical processing methods are usually used to repair it. Grinding machines, milling machines and other equipment are used to cut the depressed parts to make them flat again. This repair method is suitable for situations where the roller damage is relatively minor. Only simple repair treatment is performed on the damaged parts of the roller. However, when the damage is severe and deep depressions appear, this method is not suitable for processing the roller and cannot repair the severely damaged parts. The staff has improved the mechanical processing repair method and set the simple grinding repair process to a method of welding first and then repairing to meet the processing needs when the damage is severe.

[0004] However, in the actual roll repair process, the damaged parts of the roll are repaired by welding. Due to the complex structure and different shapes of the roll body, the welding slag will fall to other parts of the roll, which increases the difficulty of roll repair and affects the roll repair efficiency, which will eventually affect the production quality of stainless steel welded pipes. A stainless steel welded pipe roll deformation correction device and a correction process are proposed to improve the existing problems. Summary of the invention

[0030] (2) By setting a protective cover and a telescopic spring, the protective cover is used to protect the remaining unprocessed parts of the roller body.

[0059] Embodiment 2: The existing mechanical repair of deformation of rolling mill rolls is a simple repair by grinding, which is unable to repair seriously sunken parts. The staff repairs the sunken parts by welding. However, during the repair welding process, direct welding is adopted, and the unwelded parts are not protected. The dropped welding slag will affect the rest of the rolling mill roll, requiring secondary repair, which increases the difficulty of repair.

[0060] To this end, a welding head mechanism 28 is provided at the bottom of the welding pipe 27, and the external structure of the welding head mechanism 28 is set to protect the unwelded part of the roller body 18 by using the external structure of the welding head mechanism 28 to protect the unwelded part of the roller body 18. The specific structure of the welding head mechanism 28 is as follows:

[0061] In this embodiment, refer to Figure 5 and Fig.10The welding head mechanism 28 includes a fixed seat 281, which is rectangular in shape. A welding head body 282 is provided in the middle of the fixed seat 281. One end of the welding head body 282 is fixedly connected to the welding pipe 27, and the other end of the welding head body 282 is in contact with the roller body 18. The welding head body 282 performs targeted processing and welding on the roller body 18. Two sets of protective covers 284 are provided on the outside of the welding head body 282. The protective covers 284 are used to protect the remaining unprocessed parts of the roller body 18. Each protective cover 284 is connected to the welding head body 282. A plurality of telescopic springs 283 are arranged in the middle position of the fixing seat 281. The telescopic springs 283 will be squeezed when the welding head body 282 contacts the raised texture of the roller body 18. If the welding head body 282 moves to the recessed position of the roller body 18, the telescopic springs 283 will be in an extended state. The extended and squeezed telescopic springs 283 can adapt to the special shape of the roller body 18 and can be adaptively used for welding protection of different rollers, thereby avoiding the influence of welding slag on the unprocessed part of the roller body 18 and achieving the purpose of protecting the roller body 18.

[0062] See also Figure 5 and Fig.10 The protective cover 284 is hollow inside, and a welding head body 282 is arranged inside the protective cover 284. A chamfer 285 is arranged at the bottom of the protective cover 284. The shape of the chamfer 285 is an arc. The contour shape of the roller body 18 is also an arc. The chamfer 285 is adapted to the contour of the roller body 18. Two groups of gaps 286 are arranged through the side walls of the two groups of protective covers 284. The setting of the two groups of gaps 286 has a separation effect on the two groups of protective covers 284. The two parts of the protective covers 284 are respectively provided with a telescopic spring 283. The two parts of the protective covers 284 can adaptively protect the unprocessed parts on both sides of the welding head body 282, thereby expanding the protection range.

[0071] Embodiment 5, a stainless steel welded pipe roll deformation correction process, using the above-mentioned stainless steel welded pipe roll deformation correction device, comprises the following steps:

[0072] S1. The roller body 18 is placed in the middle position of the two groups of clamping mechanisms 17. The roller body 18 is positioned and clamped by the clamping mechanism 17. After the roller body 18 is stably clamped, the second sliding mechanism 15 drives the flipping mechanism 16, the clamping mechanism 17 and the roller body 18 to move linearly up and down. The first sliding mechanism 14 drives the second sliding mechanism 15, the flipping mechanism 16, the clamping mechanism 17 and the roller body 18 to move linearly left and right. The roller body 18 is adjusted to the processing position, and then flipped by the flipping mechanism 16 to further determine the processing point of the roller body 18.

[0073] S11, after the roller body 18 is stably clamped by the clamping mechanism 17, start the first motor connected to the slider module 141, the first motor drives the screw rod 142, the screw rod 142 drives the connecting plate 143 to move left and right along the first slide rail 144, first determine the lateral position of the roller body 18, then start the second motor to drive the fastening plate 161 to move up and down along the second slide rail 151, determine the longitudinal processing position of the roller body 18, finally start the fastening plate 161 to drive the third output shaft 164 to rotate, the third output shaft 164 drives the fixing block 168 to rotate, and then the clamping mechanism 17 is driven to flip under the rotation of the fixing block 168, and finally determine the processing point of the roller body 18.

[0074] S2. After the processing position of the roller body 18 is determined, the mounting platform 25 is pushed forward by starting the second cylinder 24, and then the third slider 26 is driven to move left and right along the third slide rail 23 by starting the first cylinder 22 to determine the welding position point of the roller body 18 by the welding head mechanism 28. The roller body 18 is welded by the welding head mechanism 28 until the welding of the defective part of the roller body 18 by the welding head mechanism 28 is completed.

[0075] S21, after the processing point of the roller body 18 is determined, the second cylinder 24 drives the mounting platform 25 to move to determine the forward position of the mounting platform 25, and then the first cylinder 22 is started to drive the third slider 26 to move to determine the position of the mounting platform 25 moving left and right.

[0076] S22. After the position of the mounting platform 25 is determined, that is, the position of the welding head mechanism 28 is determined, the welding head mechanism 28 corresponds to the defect of the roller body 18, and the welding head mechanism 28 can perform welding processing on the defect of the roller body 18.

[0077] S23. When the welding head mechanism 28 welds the roller body 18, the welding head body 282 welds the defective part of the roller body 18. At this time, the chamfer 285 contacts the roller body 18. The surface of the roller body 18 is uneven. When the chamfer 285 touches the convex part of the roller body 18, the telescopic spring 283 will be compressed. When the chamfer 285 contacts the concave part of the roller body 18, the telescopic spring 283 is in a stretched state. According to the moving state of the telescopic spring 283, the two sets of protective covers 284 accurately protect the unprocessed parts of the roller body 18 until the defective part of the roller body 18 is welded by the welding head body 282.

[0078] S3. After the welding head mechanism 28 completes the welding of the roller body 18, the roller body 18 is moved to the position of the grinding assembly 3 under the drive of the transfer assembly 1. The grinding assembly 3 grinds the protrusions at the welding position of the roller body 18 until the roller body 18 is ground flat.

[0079] S31. After the defective part of the roller body 18 is welded, the roller body 18, driven by the transfer assembly 1, moves up and down and left and right to reach the processing position of the grinding assembly 3. At this time, the third cylinder 36 is started to control the fourth slider 33 to move along the fourth slide rail 32 to the opposite side of the roller body 18. At this time, the grinding head 37 corresponds to the welding part of the roller body 18, and the grinding head 37 grinds the welding protrusion of the roller body 18 until the welding protrusion of the roller body 18 is polished flat.

[0080] S4. After the grinding assembly 3 grinds the welding protrusions of the roller body 18 to make it smooth, the roller body 18 is moved to the position of the polishing assembly 4 through the transfer assembly 1, and then the polishing assembly 4 polishes the grinded part of the roller body 18 until the polishing of the roller body 18 is completed.

[0081] S41. After the welding protrusions of the roller body 18 are polished and smooth, the roller body 18, driven by the transfer component 1, reaches the processing position of the polishing component 4 through left and right translation and up and down linear movement, and then the fourth cylinder 45 is started to control the fifth slider 44 to move along the fifth slide rail 43 to the opposite side of the roller body 18. At this time, the polishing mechanism 48 corresponds to the grinding position of the roller body 18, and the polishing mechanism 48 polishes the roller body 18 until the roller body 18 is polished.
