Embodiment Construction

[0030] The present invention will be described in further detail below by means of specific embodiments:

[0031] The processing technology of the direction column includes the following steps: 1. cutting; 2. screening; 3. preheating; 4. preliminary forging; 5. edge trimming; 6. polishing; 7. heat treatment; 8. milling and locking plane; Drilling three major holes; 10. Inspection; 11. Welding standpipe; 12. Reaming; 13. Breaking side holes;

[0032] details as follows:

[0033] 1. Cutting: the steel pipe is cut by an automatic cutting machine with the same frequency, and a steel pipe with a length of 30cm is cut out, and a feeding mechanism and a transmission mechanism are installed on the cutting machine. The automatic cutting machine realizes the steel pipe through the cooperation of two cams. Carry out cutting, and set a feeding mechanism at the place where the steel pipe is cut to automatically feed the steel pipe, and set a transmission mechanism directly below the cutte...

Abstract

The invention belongs to the technical field of combined machining, and specifically discloses a machining process for a direction column. The machining process comprises the following steps: 1. cutting; 2. screening; 3. preheating; 4. primary forging and pressing; 5. trimming; 6. polishing; 7. heat treatment; 8. locking plane milling; 9. drilling for three large holes; 10. detection; 11. vertical tube welding; 12. reaming; 13. side hole breakage; 14. deburring; 15. oiling; and 16. painting. The machining process solves the problems of a low strength, a high possibility of oxidation rusting, and a high defective rate of a direction column produced by the prior art.

Description

technical field [0001] The invention belongs to the field of combined processing, and in particular relates to a processing technology of a direction column. Background technique [0002] The steering column is generally composed of a standpipe and a connecting plate, and is an important part of the motorcycle steering system. The motorcycle combines the front shock absorber, front wheel, etc. with the frame, handlebars, etc. through the steering column, and most of the steering and steering of the motorcycle need the steering column to complete. The upper end and the middle and lower part of the standpipe are supported on the frame by bearings, and the lower end of the standpipe is provided with a steering pipe installation hole for the installation of the steering pipe, and the middle part of the standpipe is provided with a mounting hole connected with the steering lock. . [0003] The traditional processing technology of the direction column is: 1. Drilling the side ho...
