Embodiment Construction

[0017] The following examples describe in further detail specific embodiments of the present invention. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] A manufacturing process of a shaft coupling, comprising the following steps:

[0019] a. Put the steel ingot into the furnace and heat it to 1120°C, press the pliers to hold the material, gnaw the bottom, and chamfer the edge;

[0020] b. Reheat the billet obtained in step a to 1200-1250°C, upsetting, elongating, and opening as much as possible. The first forging ratio is controlled at 2.0-2.5;

[0021] c. Reheat the billet obtained in step b to 1100-1150°C, upsetting, elongating, flattening the end surface and printing according to the drawing number;

[0022] d. Reheat the billet obtained in step c to 1000-1050°C, and upset and form the flange end of the back-end tooth billet in the die ring;

[0023] e. Reheat the billet obtain...

Abstract

The invention discloses a manufacturing process for a shaft coupler. The manufacturing process comprises the following steps of: a, putting steel ingot into a smelting furnace to heat to 1120 DEG C, clamping the steel ingot by a pressure clamp, performing bottom chewing on the steel ingot and chamfering the steel ingot; b, re-heating the blank obtained in the step a to 1200-1250 DEG C, upsetting the blank, drawing out the blank, cogging down the blank, and controlling a primary forging ratio to 2.0-2.5; c, re-heating the blank obtained in step b to 1100-1150 DEG C, upsetting the blank, drawing out the blank, flattening the end surface of the blank and printing the blank according to a figure number; d, re-heating the blank obtained in step c to 1000-1050 DEG C, and putting the blank into a mould ring to upset and form a rear-end gear blank flange end; e, re-heating the blank obtained in step d to 950-1000 DEG C, drawing out a small shaft end of the blank to a process dimension by a core rod, controlling a shaft end total forging ratio to be greater than or equal to 5, trimming and straightening the blank; f, mounting a semi-finished product obtained in the step e into a processing center to process, firstly processing the outline of the semi-finished product and then processing an inner hole; and g, performing thermal treatment on the semi-finished product obtained in step f, and coating the processed semi-finished product for preservation. The manufacturing process for the shaft coupler disclosed by the invention is long in service life.

Description

technical field [0001] The invention belongs to the field of manufacturing technology of a shaft coupling, and in particular relates to a manufacturing technology of a shaft coupling. Background technique [0002] Couplings belong to the category of general mechanical parts. They are used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque. They are commonly used parts in the machinery industry and are in great demand. , mostly forging is used to make blanks, and then processed. Due to the special structure of some products, the traditional forging process cannot meet their production requirements, so the production and forging efficiency is low, and the service life is low. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to propose a manufacturing process of the shaft coupling to solve the problem of lo...
