Abstract
A bit welding device comprises a shell and gas inlets arranged on a side wall of the shell. A welding platform is fixed in the shell, one end of the welding pipe is connected to a high-frequency welder, the other end of the welding pipe is arranged above the welding platform, the welding pipe arranged on the welding platform is in a shape of a screw, and the center line of the welding pipe is perpendicular to the welding platform. A welding piece is disposed between a steel drill and a diamond bit and in the screw of the welding pipe 4, inert gas is filled into the shell through the gas inlets, the high-frequency welder transmits heat energy to welding materials for heating through the welding pipe so as to enable the welding materials to be heated, and the welding piece is thermally melted under an oxygen-lacking or oxygen-free condition to connect the steel drill with the diamond bit. The bit welding device has the advantage that damages to the bit caused by welding are reduced.
Description
Technical field
The utility model relates to a kind of welder, particularly a kind of drill bit welder.
Background technology
In daily production drill bit, golden steel diamond bit is loaded onto in need to adding at the ready-made steel brill of system body front end of having, and golden steel bit affects the quality of drill bit in the situation that oxidation reaction very easily occurs the high temperature polyoxy.
Summary of the invention
The purpose of this utility model provide a kind of efficient, reduce welding to the hurtful welder of drill bit.
The purpose of this utility model is achieved in that the drill bit welder comprises housing and is located at air inlet on the housing sidewall, jig is fixed in housing, welded pipe one end is connected with high-frequency induction welder, the other end is arranged at the jig top, welded pipe in the shape of a spiral, its center line is perpendicular to jig.
All right, three air inlets are uniformly distributed on the housing sidewall.
This practical advantage is: when using above structure, bonding pad is placed between steel brill and the golden steel diamond bit, and be positioned in the welded pipe helical form, start the high-frequency induction welder that welded pipe one end connects, utilize simultaneously the air inlet filling with inert gas in the housing on the housing sidewall, be full of housing at inert gas, greatly reduce oxygen content in the housing, form the welding surroundings of a few oxygen or anaerobic, reduce or avoided oxidation reaction, effectively reduce the infringement that welding causes drill bit, welded pipe has increased welded pipe and the contact-making surface that needs the welding thing in the shape of a spiral, has improved welding efficiency; Three air inlets are uniformly distributed on the housing sidewall, improve the inert gas intake efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the drill bit welder comprises housing 1 and is located at air inlet 2 on housing 1 sidewall, three air inlets 2 are uniformly distributed on housing 1 sidewall, jig 3 is fixed in housing 1, welded pipe 4 one ends are connected with high-frequency induction welder 5, the other end is arranged at jig 3 tops, be arranged on the jig 3 welded pipe in the shape of a spiral, its center line is perpendicular to jig 3.
Operation principle: bonding pad is placed between steel brill and the golden steel diamond bit, and be positioned in welded pipe 4 helical forms, by air inlet 2 to housing 1 interior filling with inert gas, start high-frequency induction welder 5, high-frequency induction welder 5 is given by welded pipe 4 conduction heat energy and is needed the heating of welding thing, the welding thing is heated up, at the situation bonding pad generation thermosol of few oxygen or anaerobic, connect steel and bore and golden steel diamond bit.
