Cutting equipment and cutting process of bearing ring

Abstract

The invention discloses cutting equipment and a cutting process of a bearing ring, and relates to the technical field of bearing ring machining equipment. The cutting equipment specifically comprisesa base, a lifting mechanism, a linear cutting mechanism, a clamping mechanism, a supporting mechanism and a bearing ring reinforcing mechanism, wherein an air vertical plate is welded to an upper portion of an end face of the base, and the lifting mechanism is slidably mounted on a rear side vertical plate; the linear cutting mechanism is arranged on a front side vertical plate, a sliding seat isinstalled above a surface of the base in a sliding mode, the clamping mechanism is vertically arranged above the sliding seat, the supporting mechanism is horizontally welded to a side wall of the sliding seat, and the bearing ring reinforcing mechanism is installed above the sliding seat. According to the cutting equipment and cutting process of the bearing ring disclosed by the invention, through the arrangement of the lifting mechanism, a stable supporting effect is provided for the bearing ring while the bearing ring is subjected to cutting machining, so that the bearing ring is not proneto shaking or vibrating, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing ring processing equipment, in particular to a bearing ring cutting device and a cutting process thereof. Background technique [0002] The bearing ring is a ring-shaped part of a radial rolling bearing with one or several raceways. It is mostly made directly by forging. If overburning, overheating, and internal cracking into network carbides during the forging process will reduce the bearing ring Toughness and strength, so it is necessary to strictly control the processing temperature, cycle heating and heat dissipation conditions after forging (such as spray cooling), especially after the final forging of large size ferrules, the temperature is above 700 ℃, and they must not be piled up. [0003] Although the existing bearing rings can be directly made by forging process, some bearing rings of special sizes need to be cut twice, so cutting equipment is needed. When the ring is cut, after the bea...

Problems solved by technology

[0003] Although the existing bearing rings can be directly made by forging process, some bearing rings of special sizes need to be cut twice, so cutting equipment is needed. When the ring is cut, after the bearing ring is in contact with the cutting mechanism, it is affected by the vibration of the machine tool or other external forces, and the bearing ring is prone to vibration problems, which will cause the cutting surface to be not smooth enough, the cutting effect is not good, and there are errors

[0004] A cutting head of a bearing ring cutting machine disclosed in the Chinese invention patent application publication CN103331490A, although the cutting head of the bearing ring cutting machine has finished processing a section of bearing ring, the hydraulic pusher is started to make the cutter return to the cutting head. Back, and then start the hydraulic pushing body 2 to drive the slope elastic chuck 1 to move forward through the workpiece guide tube to loosen the workpiece, and also start the oil cylinder 3 at the same time, so that the oil cylinder piston rod 3 drives the slope elastic chuck 2 to reset, loosen the workpiece, The cut bearing ring falls off automatically. When the cut bearing ring falls off automatically, the workpiece located in the workpiece guide tube automatically moves forward until the front end of the workpiece bears against the end face of the size limit column, and then starts to repeat the previous processing action , which is processed sequentially, which effectively improves the processing efficiency. However, the cutting head of the bearing ring cutting machine completely wraps the workpiece, which is not conducive to chip removal and heat dissipation
