Problems solved by technology

The entire machining process is completely realized by machining. Obviously, because the flange is protruding, a large amount of raw materials will be cut during the machining process, and the bar needs to be drilled, which is cumbersome, time-consuming and labor-intensive.
In addition, after processing such as drilling, it will also affect the strength of the spindle.

Embodiment 1

[0037] Such as figure 1 As shown, the main shaft of the lathe includes a cylindrical shaft body 1 and a flange 2 located at the end of the shaft body. The flange 2 protrudes from the end of the shaft body 1 in a ring shape.

[0038] The processing method of this lathe spindle comprises the following steps:

[0039] A. Material selection: Select the raw material of seamless steel pipe with a diameter of 100 mm and a wall thickness of 21 mm, and cut a pipe section that meets the length from the raw material by a sawing machine.

[0040] B. End heating: Heat one end of the above-mentioned pipe section to 750°C by electric heating.

[0041] C. End forging: place the heated pipe section in the positioning mold and make the heated end of the pipe section protrude from the positioning mold. There is a forming mold on the forging equipment. After heating, the heated end of the pipe section extends out of the positioning mold, and the forging equipment moves At the same time, the hea...

Embodiment 2

[0048] The processing method of this embodiment is basically the same as that of the embodiment, except that: in step A, the seamless steel pipe material with a diameter of 110 mm and a wall thickness of 18 mm is selected; in step B, the first heating temperature of the pipe section is 1070 ° C, and The secondary heating temperature is 1060°C, and the forging equipment is a 45-ton forging bed.

Abstract

The invention provides a method for processing a lathe spindle, belonging to the field of mechanical technology. By means of the method, the problems of serious waste of materials and cumbersome processing in a conventional processing method of the spindle are solved. The method for processing the lathe spindle comprises the following steps of: A, material selecting; B, end heating; C, end hammering; D, machining; and E, surface treatment. The method for processing the lathe spindle has the advantages of material saving, strong stability in flange forming and high processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a lathe, in particular to a processing method for a lathe spindle. Background technique [0002] Machine tool is an important tool for human beings to carry out productive labor, and it is also an important symbol of the development level of social productivity. Ordinary machine tools have experienced nearly two hundred years of history. Lathes are one of the machine tools. Lathes have shown their unique superiority and strong vitality in machining operations, and have found effective solutions to many problems that could not be solved before. . Lathe is a kind of equipment with good versatility, high processing precision and high processing efficiency. It is the most widely used machine tool in China with the widest coverage. [0003] Among them, the main shaft is a particularly important part in the lathe. It is installed at the head box of the lathe. One end of the main shaf...
