Embodiment Construction

[0020] Equipment layout and equipment function of the present invention and the annex (punching, extruding die) on the equipment require:

[0021] 1. The principle of making the workpiece flow fast and short in the layout of the equipment is placed in the shape of "工";

[0022] 2. There are three processing stations on the presses of the equipment (2, 5) so that the processing time of the workpiece is short and the speed is fast;

[0023] 3. Medium frequency induction heating is adopted, with fast speed and stable heating;

[0024] 4. In the back-extrusion die on the equipment, the weight of the forging punching core is adjusted by means of an adjustable pad, so that there is enough forging material to enter the second and third sets of forgings in the subsequent process, that is, the back-extrusion punch passes through Add or subtract to adjust the thickness of the pad to control the distribution of materials.

[0025] The equipment 1 described in the present invention is a...

Abstract

The invention discloses a process for forging and molding three connecting kits of a bearing ring roughcast. On equipment which is put in an I-shaped arrangement, a metal material section is sent to an intermediate frequency heating furnace of equipment 1; after the heating temperature of the metal material section reaches between 1,200 and 1,250 DEG C, the metal material section is sent to the equipment, is subjected to continuous upsetting, back extrusion, punching and ring rolling; and the bearing ring roughcast after chambering is subjected to finishing and correction to complete the processing of the first kit, the second kit and the third kit (the ring roughcasts). The process for forging and molding three connecting kits of the bearing ring roughcast can fully utilize residual materials, achieve effective conservation of the materials, simplify the production process, improve production efficiency and complete the production of a plurality of forging pieces of the bearing ring roughcast on one production line under the condition of not increasing the consumption of the raw materials.

Description

technical field [0001] The invention relates to a forging process technology of a metal ferrule, in particular to a forging forming process of a bearing ring blank triple set, and belongs to the technical field of metal thermal processing. Background technique [0002] In the traditional processing methods of bearing ring blanks, most of them use high-temperature forging and then mechanical cutting. This manufacturing process makes materials and energy consumption account for 60%-70% of the total cost, which is no longer possible. It is suitable for the production requirements of forging and forming of bearing ring blanks. In order to reduce the cost of forgings, it is necessary to increase material utilization, reduce energy consumption, and increase productivity, which is also the direction that the forging industry has been striving for. [0003] In order to solve the problems of low production efficiency and high cost of bearing rings, people continue to study and make ...
