Abstract
The utility model belongs to the field of a mechanical machining cutter, and particularly relates to a welding molding cutter, and the welding molding cutter comprises a cutter holder and a cutter head, wherein the cutter holder is in welding connection with the cutter head, the top end of the cutter holder is provided with a V-shaped groove, and the lower end of the cutter head is provided with an oblique-wedge welding surface corresponding to the V-shaped groove; and the cutter head is a drilling tool, a milling tool or other forming tool. The welding molding cutter has advantages that the manufacturing cost of the cutter is greatly reduced, the service life is long, and the cutter is not easy to break.
Description
Technical field
The utility model relates to the machine tools field, particularly a kind of brazed shank tool by welding fabrication.
Background technology
Cutter is instrument commonly used in the machining, it also is a kind of consumptive material in the machining, work in-process, breakage occurs in the cutter head of cutter easily, therefore, and in some fields, the hardness requirement of cutter cutter head is higher, if but whole cutter adopts the integrated words of hard material, cost can be very high, therefore, usually need to adopt other materials as knife bar, be combined with each other with cutter head, existing cutter head and cutter connected mode are direct welding mostly, and joint face is the plane, like this, when cutter in use, stress point concentrates on the pad, easily fracture.
Summary of the invention
The purpose of this utility model is for the one-body molded cost of existing cutter described in the background technology too high, and composite molding is the problem of easy fracture then, and a kind of welding fabrication cutter that can solve foregoing problems is provided.
It is as follows to solve goal of the invention technical scheme of the present utility model:
A kind of welding fabrication cutter, it comprises knife bar and cutter head, and knife bar and cutter head are welded to connect, and the knife bar top is provided with V-shaped groove, and the lower end of cutter head is provided with the wedge solder side corresponding with V-shaped groove.
Described cutter head is for boring cutter, milling cutter or other forming cutters.
The cost of making in order to save cutter, described knife bar are the chromium steel material.
For the steadiness that guarantees that knife bar is connected with cutter head, the angle of described V-shaped groove is 60 °～110 °.
The advantage of welding fabrication cutter of the present utility model is because the knife bar top is provided with V-shaped groove, the cutter head lower end is provided with the wedge solder side corresponding with V-shaped groove, after the welding, contact-making surface between cutter head and the knife bar is the wedge solder side, cutter in use, the force part mainly on the wedge solder side, welding position stressed very little, therefore, cutter is difficult for fracture.
Description of drawings
Fig. 1 is the schematic diagram of welding fabrication cutter of the present utility model;
Among the figure, 1 is knife bar, and 2 is cutter head, and 3 is V-shaped groove, and 4 is the wedge solder side.
The specific embodiment
With reference to a kind of welding fabrication cutter shown in Figure 1, it comprises knife bar 1 and cutter head 2, and knife bar 1 is welded to connect with cutter head 2, and knife bar 1 top is provided with V-shaped groove 3, and the lower end of cutter head 2 is provided with the wedge solder side 4 corresponding with V-shaped groove.
Cutter head 2 described in the aforementioned schemes can be to bore cutter, milling cutter or other forming cutters.
The cost of making in order to save cutter, described knife bar 1 are the chromium steel material.
For the steadiness that guarantees that knife bar is connected with cutter head, the angle of described V-shaped groove 3 is 60 °～110 °.
