Spinning machining device for blank bar for bearing production

Abstract

The invention discloses a spinning machining device for a blank bar for bearing production, and relates to the technical field of bearing machining. The problems that an existing shaping device generally performs shaping in a die extrusion mode, parts with different diameters need to correspond to different dies, the dies need to be repeatedly disassembled, the using effect is poor, and meanwhile, the machining efficiency is low are solved. The spinning machining device comprises a mounting base, a feeding driving part, an extrusion sliding seat and a lower extrusion sliding part. The feeding driving part is fixedly connected to the right side of the mounting base. The extrusion sliding seat is connected to the upper part of the mounting base in a sliding manner. The lower extrusion sliding part is connected to the upper part of the rear part of the extrusion sliding seat in a sliding manner. According to the spinning machining device for the blank bar for bearing production, an outer circle of a workpiece is extruded through rotary extrusion machining, shaping of the outer circle of the workpiece is achieved, meanwhile, the density of a machined bar is higher, the strength of parts can be greatly improved, machining of the parts with different diameters can be achieved, universality is good, and machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a spinning processing device for blank bars used in bearing production. Background technique [0002] In the bearing production process, the bar is generally used as the blank. Before the bar is used, it is generally necessary to shape the bar to ensure the roundness of the bar and facilitate post-processing. For example, application number: CN201510834111.7 The present invention discloses a pipe shaping machine, which includes an upper mold assembly with a template and a pressing die, a lower mold assembly, and a push-out mechanism arranged in the frame. The upper mold assembly is Movable, an intermediate connecting plate is set between the upper mold assembly and the lower mold assembly, the intermediate connecting plate is connected to the lower mold assembly through a guide column, and one end of it is connected to a rotatable ejection mechanism, and the upper mold...

Problems solved by technology

[0004] The object of the present invention is to provide a spinning processing device for rough blanks used in bearing production, to solve the problem that the existing shaping devices proposed in the above background technology generally carry out shaping by means of die extrusion, different diameters The parts need to correspond to different molds, and the mold needs to be disassembled repeatedly. At the same time, the roundness effect after plastic surgery is not ideal, the use effect is not good, and the processing efficiency is low.
