Example Embodiment

[0024] The technical solutions of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] see figure 1 , the present embodiment is a method of processing a diamond engineering thin-walled drill base. First, determine the components of the diamond engineering thin-walled drill base, which is composed of three parts: a steel pipe body 1, a joint piece 2 and a joint 3, wherein the steel pipe body 1 The raw material is obtained by cold gadolinium method, the outer diameter of the joint piece 2 and the outer diameter of the steel pipe body 1 are machined and polished to the same size after welding, and the shape of the joint 3 is a hexagonal nut shape.

[0026] There is a boss 21 at the connection part between the joint piece 2 and the steel pipe body 1, such as figure 2 As shown, the outer diameter of the boss 21 is a clearance fit with the inner diameter of the steel pipe body 1 . 8 tooth r...

Abstract

The invention relates to the technical field of core drill bits, in particular to a processing method for an engineering diamond core drill matrix, which aims to solve the problems of low efficiency, low precision and more loss of traditional engineering diamond core drill matrix processing technique. The processing method is characterized in that the engineering diamond core drill matrix comprises a steel pipe, a joint piece and a joint, the outer diameter of the joint piece is equal to that of the steel pipe, a boss is arranged at the connection position of the joint piece with the steel pipe, the outer diameter of the boss is in clearance fit with the inner diameter of the steel pipe, a plurality of concave teeth are evenly distributed on the periphery of an inner hole of the joint piece, convex teeth matched with the concave teeth are arranged at one end of the joint, the steel pipe is processed and clamped by an elastic sleeve device of a center frame, the elastic sleeve device is provided with a tubular elastic sleeve, a steel pipe positioning seat is arranged at one end of an inner hole of the elastic sleeve, a plurality of through grooves are axially arranged on the wall of the elastic sleeve, and a positioning sleeve and a locking nut are mounted on the outer circumference of the elastic sleeve. Fewer raw materials are consumed, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of thin-wall drill manufacturing, in particular to a method for processing a diamond engineering thin-wall drill matrix. Background technique [0002] Diamond engineering thin-wall drill bits are widely used in scientific research and construction engineering reinforced concrete drilling, walls, roads, airports and other infrastructure, ceramics, glass and other building materials and brittle hard non-metallic materials, as engineering consumables , not only require high technical indicators such as wear resistance and service life, but also have strict requirements on the coaxiality and concentricity of the drill bit. Diamond engineering thin-walled drills have decades of processing history in China. The traditional process is to directly process thick-walled pipes with a wall thickness of 9mm to 12mm, and finally process them to a finished product with a wall thickness of 2mm to 3mm. Obviously, such as lo...
