Embodiment Construction

[0014] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Figure 1a It is a structural diagram of a drill reamer. The left cutter head 2 is a hard alloy with a grade of K10, and the right handle 5 is a steel with a grade of 40Cr. refer to Figure 1b , V-shaped welding is adopted, and the V-shaped welding surface 9 is shown in the figure, which can increase the welding area and combine more firmly.

[0016] figure 2 is a welding schematic. The device includes a cylinder 1, a cutter head 2, an induction coil 3, a sandwich welding piece 4, a knife handle 5, a fixed seat 6, a base 7 and a high-frequency welding machine 8. The connection relationship is shown in the figure. Stand up the knife handle 5 during welding, first smear the solder paste on the welding surface, put the sa...

Abstract

The invention discloses a method for welding a double-metal drill reamer, which is used for welding a drill reamer comprising a reamer head and a reamer handle. The method comprises the following steps: erecting the reamer handle; coating soldering paste on a welding surface, and putting on a soldering lug; aligning the reamer head and the reamer handle; applying pressure; welding by a welding machine; controlling welding temperature and welding time, wherein the welding surface of the reamer head and the reamer handle is in a V shape; and after the reamer head and the reamer handle are welded, keeping warm for the drill reamer. Based on the method, the reamer head and the reamer handle made of two different materials are firmly welded, thereby eliminating internal stress. The drill reamer has small possibility of deformation and has good precision.

Description

technical field [0001] The invention relates to a metal cutting tool for machining holes, in particular to a welding method for a bimetallic drill reamer. Background technique [0002] In order to reduce the cost of tools, under the premise of ensuring the normal use of tools, two different materials (tungsten carbide and steel) are often used to manufacture drills, reamers, etc. However, the cutting tools of the two materials have the following defects when they are welded: weak welding, internal stress, deformation and poor precision of the cutting tools. Contents of the invention [0003] The purpose of the present invention is to provide a bimetallic drill reamer welding method. Based on the present invention, the drill or reamer made of two different materials can be firmly welded, the internal stress is eliminated, and the deformation is not suitable and has good precision. [0004] The invention discloses a method for welding a bimetallic drill reamer. The method i...
