Production technology for diamond thin-wall drill base body

Abstract

The invention discloses a production technology for a diamond thin-wall drill base body. The production technology comprises the steps that firstly, pipe body machining is conducted, wherein a, plate tailoring is conducted, the length and the width of a pipe body are calculated, and discharging is conducted through a plate shearing machine; b, pipe rolling is conducted, and plate rolling forming is conducted on a plate through a four-roller pipe rolling machine; c, welding is conducted, an argon arc welding machine is adopted for spot welding, then wire filling is conducted through the argon arc welding machine for outer circle welding, and then the argon arc welding machine is adopted for inner hole welding; d, shaping is conducted, and a shaping machine is adopted for roundness shaping; and e, circle correcting is conducted, a linear axial circle correcting machine is adopted for circle correcting, and the roundness of the pipe body is technically required to be within 0.3 mm; and secondly, pipe body and connector disc welding is conducted, the position of a welding head of the argon arc welding machine is adjusted, the welding head corresponds to the connecting position of the pipe body and the connector disc, and pipe body and connector disc welding is conducted. According to the production technology, the machining efficiency is high, time is short, losses are low, concentricity is high, the yield is increased, and the service life is prolonged.

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...
