Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of turning processing equipment, in particular to a turning device for roller processing. BACKGROUND

[0002] The roller is the main working component and tool for continuous plastic deformation of metal on the rolling mill. The roller can be arranged in the form of two rollers, three rollers, four rollers or multiple rollers in the rolling mill stand. The roller is mainly composed of a roller body, a roller neck and a shaft head. The roller body is the middle part of the roller actually participating in the rolling of metal. It has a smooth cylindrical surface or a surface with rolling grooves. The roller neck is installed in the bearing and transmits the rolling force to the stand through the bearing seat and the pressing device. Roller repair refers to repairing the roller that has failed due to wear, cracks, fatigue and other damages through repair technology, so as to restore it to the original design size or meet specific use requirements. Turning is an important way of roller repair and an important means to ensure the performance of the roller. The surface of the roller is cut and processed by a lathe to remove the wear layer, so as to restore the surface precision of the roller. It has the advantages of simple process and smooth surface after repair.

[0003] The Chinese patent document with publication number CN210817484U discloses a lathe for cutting roller blanks, which comprises a lathe body, a positioning mechanism and a balancing mechanism. The positioning mechanism comprises a positioning block on the top surface of the lathe body. The front and rear surfaces of the lathe body are provided with limiting sliding grooves. The two sides of the top surface of the lathe body are provided with dovetail grooves. The dovetail grooves are provided with dovetail blocks inside. The front and rear surfaces of the positioning block are provided with fixed blocks. The limiting sliding grooves are provided with fixed bolts inside. One end of the fixed bolt is located on the outer surface of the lathe body, and the fixed bolt penetrates through the one side surface of the fixed block. The end of the fixed bolt located inside the limiting sliding groove is provided with a fixed nut. During processing, first, the roller blank is placed on the mounting frame to position and install the roller. Then, the fixed nut and the fixed bolt are rotated to change the distance between them, loosen the clamped fixed block, and make the fixed bolt movable inside the limiting sliding groove. Then, the position of the positioning block is moved, and the dovetail block at the bottom end surface of the positioning block slides inside the dovetail groove to adjust to the appropriate position. Then, the fixed block is fixed by rotating the fixed bolt, and the positioning device is adjusted. When the height of the lathe needs to be adjusted, the limiting clamping block is pulled down, the spring is compressed under stress, the handle is rotated, the handle drives the gear to rotate, the gear drives the height of the limiting rack to change, the appropriate height is adjusted, the limiting clamping block is loosened, the spring pushes the limiting clamping block upward without stress, and the top end of the limiting clamping block is clamped in the clamping groove.

[0004] In the above technology, when the turning tool performs turning on the rotating roll, a large amount of metal cutting chips are generated. On the one hand, some of the longer cutting chips will rotate with the roll. When the cutting chips rotate, they will rub against the workpiece surface, which can easily cause damage to the workpiece surface. On the other hand, some of the shorter cutting chips will fall onto the lathe, affecting the normal turning of the roll and resulting in poor machining quality of the turning device. Summary of the Invention

[0005] This invention provides a turning device for rolling mill processing, aiming to solve the technical problem of poor processing quality in existing turning devices.

The cutting disc is disposed on the worktable. The adjustment component energizes the adsorption roller, causing the chips to be magnetically attracted and adsorbed onto the adsorption roller. The adsorption roller is moved to the cutting disc, where the adsorption roller and the cutting disc compress and cut the chips. The adjustment component de-energizes the adsorption roller, and the chips fall into the collection box.

[0007] Beneficial effects: By adjusting the device, the adsorption roller is energized, and the adsorption roller can adsorb the cutting chips generated by the roll during the turning process. Then, the adsorption roller is moved towards the cutting disc, and the cutting chips on the adsorption roller are squeezed as the cutting disc and the adsorption roller gradually approach each other. Then, the cutting disc cuts the longer and shorter cutting chips. Finally, the adsorption roller is de-energized by adjusting the device, and the cutting chips fall into the collection box, thus completing the processing and collection of cutting chips and improving the processing quality of the turning device.

[0018] Beneficial effects: through the setting of the cutting mechanism, when the adsorption roller resets to the rotating rod, the pushing assembly can push the cutting chips adsorbed on the rotating rod and arrange them, and then cut them off by the cutting knife; when the adsorption roller slides away from the rotating rod and slides to the cutting disc, the pushing assembly can push the cut chips in the adsorption roller out; since the magnetic force of the adsorption roller is greater than that of the rotating rod, when the adsorption roller moves to the collection box, it can drive the chips to move simultaneously.

[0043] The implementation principle of the turning device for roll machining is as follows: when the roll needs to be machined, the roll is first installed between the clamping chuck and the positioning mechanism, then the turning tool is moved to the roll through the driving mechanism, then the roll is driven to rotate by the clamping chuck, and the turning tool is moved close to the positioning mechanism by the driving mechanism, and the turning tool is used for turning the roll.

[0044] The power supply part is powered to the adsorption roller 31, the adsorption roller 31 has magnetism after being powered, when the roll rotates, the linkage disc 521 is driven to rotate, the rotating rod 522 is driven to rotate, the adsorption part 311 and the extrusion part 312 are driven to rotate by the rotating rod 522, the adsorption part 311 adsorbs the long cutting chips and the short cutting chips generated in the turning process of the roll, the long cutting chips are wound during the rotation of the adsorption part 311, the adsorption part 311 can move close to the cutting disc 33 by cooperating with the bidirectional screw rod 51 during the rotation of the adsorption part 311, and the rotating rod 522 can collect the cutting chips generated in the turning process of the turning tool during the movement of the adsorption part 311.
