Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is further described in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] A manufacturing process for a rotating shaft, comprising the steps of:

[0027] Step a, material preparation: select the bar steel material according to the diameter;

[0028] Step b, material breaking: heating the bar steel to 1000-1200 degrees Celsius, and repeatedly transporting the raw material from one axial end to the other end to the forging device and then transporting the raw material in the opposite direction. The above forging ratio forges the full length of the raw material into steel segments;

[0029] Step c, rough turning: rough turning the outer circle to remove the blank allowance with high production efficiency;

[0030] Step d, rough cutting...

Abstract

The invention discloses a rotary shaft manufacturing process. The rotary shaft manufacturing process comprises the steps of material preparation, material cutting, rough turning, cutting rough machining, semi-finish turning, grinding machine finish machining, milling machine finish machining, chamfering, deburring, heat treatment, wire cutting and the like. According to the rotary shaft manufacturing process, two central holes are adopted as the positioning reference, so that the manufacturing process is simple, the machining steps are clear, the machining efficiency is high, the effect is good, machining is convenient and rapid, the machining precision is high., the machining cost is saved, the economic benefits are increased, the batch production is facilitated, the good wear resistanceand the good toughness are achieved, so that machining parts with the high reliability in the field of aircrafts and nuclear energy.

Description

technical field [0001] The invention relates to the technical field of shaft processing, in particular to a shaft manufacturing process. Background technique [0002] Shafts are one of the main parts that make up a machine. All transmission parts (such as gears and worms) that perform rotary motion must be installed on the shaft to transmit motion and power. Therefore, the main function of the shaft is to support the rotating parts and transmit motion and power. According to the different loads of the shaft, the shaft can be divided into three types: the rotating shaft, the mandrel and the transmission shaft. The shaft that bears both the bending moment and the torque during work is called the rotating shaft, the shaft that only bears the bending moment is called the mandrel, and the shaft that only bears the torque but not the bending moment is called the transmission shaft. [0003] The rotating shaft is made of cylindrical materials. Since it is a key component, it has...
