Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] The embodiment of the present invention discloses a production process of a diamond thin-walled drill base, which not only uses the steel plate to cut and roll the tube to make the tube body, has high processing efficiency and low loss, but also welds both the inside and outside of the tube to avoid the problem of open welding ;In addition, the use of a linear axial circle calibration machine improves the concentricity of the diamond thin-walled drill ma...

Abstract

The invention discloses a production process of a diamond thin-walled drill base body, comprising: (1) processing of the pipe body: a. plate cutting: first calculate the length and width of the pipe body, and then use a shearing machine to cut the material; b .Rolling tube: Use four-roller tube coiling machine to form the plate; c. Welding: First use argon arc welding machine for spot welding, then use argon arc welding machine to fill wire for outer circle welding, and then use argon arc welding machine Carry out inner hole welding; d. Shaping: carry out roundness shaping through a shaping machine; e. Calibration: use a linear axial circle calibration machine to calibrate the circle, and the technical requirements for the roundness of the pipe body to reach within 0.3mm; (2) the pipe body Welding with the joint plate: adjust the position of the welding head of the argon arc welding machine so that it corresponds to the connection between the pipe body and the joint plate, and then weld the pipe body and the joint plate. The invention not only has high processing efficiency, short time and low loss, but also has high concentricity, which improves the yield and service life.

Description

technical field [0001] The invention relates to the field of processing and manufacturing a diamond thin-walled drill base, and more specifically relates to a production process for a diamond thin-walled drill base. Background technique [0002] As a drilling tool, the diamond thin-wall drill is mainly used to drill holes of large and small diameters in various building materials, especially in the process of laying wires or pipes, it has become an indispensable tool. [0003] Diamond thin-walled drills have been processed for decades in China. The traditional process of pipe body processing is to directly process thick-walled pipes with a wall thickness of 5mm to 20mm, and finally process them to a wall thickness of 2mm to 4mm. The problems of low efficiency, long time, and large loss, the utilization rate of raw materials is only about 20%, and the surface processing accuracy is low, and the concentricity is poor. In addition, the production of joints and joint plates is m...
