Problems solved by technology

It can solve the problem that the forging equipment used in the existing GCr15 roller sleeve has a poor shaping effect on the inner and outer circles of the roller sleeve. The forming roll is easily damaged, and the roll sleeve cannot be extended well, which has a certain impact on the poor forging effect of the roll sleeve. technical issues

Embodiment Construction

[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] see Figure 1-7 Shown, a kind of forging process of GCr15 roller sleeve comprises the following steps:

[0036] S1: first place the metal blank material horizontally on the placement frame 2 in the forging equipment, start the second motor 24, when the output end of the second motor 24 rotates, it will drive the transmission gear 25 to rotate, and when the transmission gear 25 rotates, it will drive the first A rack plate 23 and the second rack plate 26 move towards each other, and the rollers 22 on the side of the ...

Abstract

The invention relates to the technical field of roller sleeve forging, in particular to a forging process of a GCr15 roller sleeve. Forging equipment used in the forging process comprises a base, forming roller mechanisms, a top seat, an auxiliary extension mechanism and an auxiliary pressure roller mechanism, supporting seats are fixedly connected to the two ends of the top of the base, the top seat is fixedly connected to the tops of the two supporting seats, the two forming roller mechanisms are slidably mounted between the two supporting seats at the top of the base, a placement frame is fixedly connected between the two forming roller mechanisms at the top of the base, the auxiliary pressure roller mechanism is mounted between the top of the base and the bottom of the top seat, the forming roller mechanisms comprise sliding boxes, forming rollers and first motors, and the sliding boxes are installed at the top of the base in a sliding mode. According to the forging equipment used in the forging process of the GCr15 roller sleeve, the double forming roller mechanisms are arranged, so that the length of forming rollers can be shortened, the forming rollers are prevented from being bent and deformed at a high temperature, and the forging and shaping effect on the roller sleeve is prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of roller sleeve forging, in particular to a forging process of a GCr15 roller sleeve. Background technique [0002] The forging equipment of GCr15 roller sleeve is mainly used for the forging work of GCr15 roller sleeve. GCr15 is a rolling bearing steel with an average chromium content of 1.5%. , forging is a processing method that uses forging machinery to exert pressure on metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate the looseness of the metal in the smelting process, etc. Defects, optimize the microstructure, and because the complete metal flow line is preserved, the mechanical properties of forgings are generally better than castings of the same material. The existing GCr15 roller sleeve forging process is divided into three steps of heating, forming and heat treatment. [0003] The existing GCr15 rolle...
