Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, in particular to a wire drawing device for automobile wheel hub. BACKGROUND

[0002] The automobile wheel hub wire drawing equipment is an equipment used for wire drawing processing of automobile wheel hub, which is widely used in the production and processing of automobile wheel hub, is a common wheel hub surface renovation, repair and modification method, and can effectively remove the oxidation layer on the surface of the wheel hub, change the texture of the wheel hub surface, or make it present a better visual effect. When wire drawing is performed on the wheel hub, the wheel hub is usually clamped by the clamping structure of the wire drawing equipment, and then the wheel hub is rotated to process the texture on the surface of the wheel hub by using a milling cutter.

[0003] For example, patent number CN202220693784.0, a wire drawing device for automobile wheel hub forging, includes a base, a collecting hopper, a turntable and an electric sliding rail. The inside of the base is fixed with a collecting hopper, the inside of the collecting hopper is provided with a middle table, the middle of the middle table is embedded with a motor, the output end of the motor is fixed with a turntable, and the middle table is fixed in the inside of the collecting hopper through a connecting rod. The top surface side of the turntable is fixed with a fixed plate, the inside of the fixed plate is rotatably installed with a screw rod, and one end of the screw rod is rotatably connected with a clamping plate. The utility model discloses a collecting hopper, which can collect and transport the debris generated by processing the wheel hub on the surface of the turntable, achieves the effect of gathering and transmitting, and through the cooperation of the motor and the turntable, the wheel hub fixed on the surface can be rotated, which achieves the effect of rotating the wheel hub to cooperate with the wire drawing grinding head for wire drawing processing. The utility model discloses a fixed plate, a screw rod and a clamping plate, which can clamp and fix the wheel hub placed on the surface of the turntable, achieve the effect of clamping and fixing the wheel hub for wire drawing processing, and through the cooperation of the pulley and the sliding groove, the turntable can be stabilized on the side when being rotated by the motor, which achieves the effect of stabilizing the rotation of the turntable. The utility model discloses an electric sliding rail, which can change the horizontal use position of the hydraulic cylinder, achieves the effect of indirectly adjusting the use position of the wire drawing grinding head, and through the hydraulic cylinder, the height position of the wire drawing grinding head can be changed, which achieves the effect of adjusting the use position of the wire drawing grinding head. The utility model discloses a wire drawing grinding head, which can scrape and draw the wire of the wheel hub fixed on the surface of the turntable, which achieves the effect of wire drawing processing.

[0004] The above wire drawing device still has obvious deficiencies in practical application: in the wheel hub wire drawing process, a large amount of metal debris is generated, although the rotating wheel hub can make most of the debris difficult to adhere to the surface through the centrifugal force, but part of the small volume debris may still remain and adhere to the wheel hub due to the weak centrifugal force, and these residual debris will be crushed or scraped by the subsequent milling cutter, thereby forming irregular scratches and indentations on the wheel hub wire drawing surface, which not only directly destroys the uniformity of the wire drawing texture, but also causes the processing surface to be completely scrapped, and finally needs to be reprocessed.
