Abstract
Description
Technical Field
[0001] The invention relates to the technical field of steel pipe rolling processing and manufacturing, and in particular to a disassembly device for a roller assembly in steel pipe rolling manufacturing. Background Art
[0002] Steel pipe rolling technology is widely used in engineering fields such as construction, machinery, automobiles, and ships. Steel pipes produced by roll forming technology have the advantages of high strength, light weight, easy processing and installation. Steel pipe rolling technology has high production efficiency and strong adaptability. During the steel pipe rolling process, metal sheets or strips are fed into the roll forming device, which consists of a series of rollers. These rollers apply pressure to the metal sheets or strips through continuous rolling and bending, so that they are gradually deformed into the desired steel pipe shape.
[0003] In the rolling manufacturing of steel pipes, different rolls need to be replaced to meet different manufacturing needs. The rolls are clamped by a fixing mechanism. In the traditional disassembly and replacement process, it is usually necessary to remove the fixing mechanism on one side first and then gradually disassemble the roll components. However, the rolls are heavy, and direct disassembly is time-consuming and labor-intensive, which increases downtime and affects production efficiency. In addition, disassembling the roll components separately can easily lead to the scattered loss of roll components, affecting subsequent applicability and not conducive to production management specifications.

[0006] When the present invention is working, the box body is pushed toward one side of the roll assembly to the working point by the transverse movement of the worm gear box, and then the push plate is extended by the oil cylinder. After the pull rod on the push plate is synchronously extended and moved into place, the steering pull plate at the end of the pull rod rotates relatively and contacts the end of the roll spacer. Then the pull rod moves in the opposite direction under the drive of the oil cylinder, and the box body is transversely moved to the side away from the roll assembly, so that the roll assembly is pulled out of the frame of the machine base as a whole, and the disassembly of the roll assembly is completed.

[0011] Furthermore, the push plate is an I-shaped plate, and pull rods are fixedly arranged at the four end corners of the push plate, and the output shaft end of the oil cylinder outside the box body passes through the box body and is connected to the push plate; pull rods are arranged at the four end corners of the I-shaped plate to form a solid frame structure, which can resist the external torque brought by the roller assembly, avoid twisting or tilting of the roller push-pull mechanism when it is subjected to force, and can also disperse the stress when it is subjected to large loads, which is beneficial to improving the overall strength and durability of the roller push-pull mechanism.
[0012] Furthermore, the steering pull plate is rotatably clamped in the groove at the end of the pull rod through a rotating shaft, a notch is provided on one side of the groove, and the steering pull plate is rotated toward the notch to be locked with the roller spacer.
[0013] Furthermore, the roller spacer is sleeved inside the roller and passes through the roller to fix the roller to the frame, and the roller spacer facing the connecting sleeve shaft can be sleeved and fixed with the connecting sleeve shaft; after the roller push-pull mechanism moves horizontally to the working point, the end of the roller spacer is sleeved into the connecting sleeve shaft to form a stable connection, which is convenient for driving the roller assembly as a whole to be moved out of the frame.
