Abstract

The utility model provides a welding heating device which is used for heating welding flux disposed on the top of a tool rod during welding of a tool bit and the tool rod of a drill. The welding heating device comprises an ultrahigh frequency generator and an induction coil extending out from one end of the ultrahigh frequency generator. The welding heating device employs the ultrahigh frequency generator and the induction coil driven by high-frequency current to surround and heat the welding flux, and realizes easy control of temperature; the induction coil can heat the tool rod or the welding flux uniformly without being contacted with the tool rod or the welding flux, and the non-contact heating method prevents deformation and damage caused by uneven heating and excess temperature of the drill parts or the welding flux during welding, thereby improving stability and quality of welding; and, since the induction coil only heats portions requiring heating, the welding heating device guarantees uniform heating of the welding flux and prevents heat loss of the welding flux, thereby saving energy.

Description

The weld heating device

Technical field

The utility model relates to the drill bit welding technology field, relates in particular to the weld heating device that in the drill bit welding process, scolder is heated.

Background technology

Drill bit is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming.Drill bit generally adopts Hardmetal materials such as tungsten copper or tungsten-cobalt alloy to make at present, and hardness is very high, and is very wear-resisting, and certain intensity is arranged, and be suitable for high-speed cutting, but cost is higher.

The drill bit of Hardmetal materials adopts the mode of whole skiving or welding to make usually.Cutter head and knife bar that whole skiving is a drill bit are global formation, and integral body all is Hardmetal materials, accomplish the further processing of cutter head and knife bar through cutting and skiving.Because the Hardmetal materials price is higher, the drill bit that whole skiving is made is more because of the alloy material of its processing waste, and the processing cost height causes its drill bit cost of manufacture expensive.

Adopt the mode of welding cutter head and knife bar to make in order to save the present many drill bits of cost, knife bar adopts stainless steel, and the drill bit that welding method is made is saved Hardmetal materials, greatly reduces the cost of manufacture of drill bit accordingly.The welding of Hardmetal materials at present adopts manual welding to add the acetylene gas welding more, and the acetylene gas combustion high temperature adds hot solder and makes its fusing in the welding process, manual then cutter head and knife bar is linked together.But this welding method is because the temperature of flame heat and speed are difficult to control, and welding material deforms or breakage easily in the welding process, influences welding quality.

The utility model content

The utility model is exactly in order to solve the problem that above-mentioned prior art exists a kind of new type of welding heater to be provided, and the scolder that in the cutter head of drill bit and knife bar welding process, is opposite to the knife bar top heats.

The purpose of the utility model realizes through following technical scheme:

A kind of weld heating device is used for heating the scolder that places the knife bar top in the cutter head and the knife bar welding process of drill bit, comprises a ultra-high frequency generator, and an end of ultra-high frequency generator extends an induction coil.

Preferably, said induction coil is the horizontal direction setting.

Preferably, said induction coil is over against knife bar, and the knife bar top is positioned in the middle of the induction coil.

Preferably, said induction coil is the individual layer inductance coil.

Compared with prior art, the utlity model has following beneficial effect:

The weld heating device of the utility model adopts ultra-high frequency generator and the induction coil that is connected with high frequency electric to surround and adds hot solder; Temperature is easy to control; And induction coil need not to contact and can evenly heat it with knife bar or scolder; The noncontact mode of heating can prevent in the welding process that be heated inequality or Yin Wendu of drill bit assembly or scolder is too high and produce distortion, breakage, improves the stability and the welding quality of welding.Induction coil only heats the part that needs heating, and scolder is heated evenly and does not have heat loss, helps energy savings.

Description of drawings

Fig. 1 is the three-dimensional structure diagram of the utility model one embodiment;

Fig. 2 is the front view of Fig. 1;

Fig. 3 is installed on the structural representation on the operating desk for weld heating device shown in Figure 1.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing.

Fig. 1,2 is depicted as a preferred embodiment of the utility model, and Fig. 3 is installed on the structural representation on the operating desk 100 for weld heating device shown in Figure 1.A kind of weld heating device is used for heating the scolder that places the knife bar top in the cutter head and the knife bar welding process of drill bit, comprises a ultra-high frequency generator 1, and an end of this ultra-high frequency generator 1 extends an induction coil 2, and induction coil 2 is the individual layer inductance coil.

Ultra-high frequency generator 1 is installed on the operating desk 100; Induction coil 2 is horizontal direction setting and over against knife bar 101; In the welding process, the top of knife bar 101 is positioned in the middle of the induction coil 2, and induction coil 2 produces high temperature through high frequency electric; Add hot solder (placing the knife bar top) to fusing, then cutter head and knife bar are coupled together the formation drill bit.

More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
