Abstract
The present invention relates to a kind of double metal grinding hardware tool, comprise shank and operate portions, its manufacture craft comprises shank procedure of processing, operate portions procedure of processing and welding step, it is characterized in that: described welding step is, earlier shank and operate portions after handling through processing are heated pressurization welding behind the arrival melt temperature separately respectively.Because the present invention has taked above technical scheme, operate portions adopts different metal ingredients with shank, and melt soldering by the special process electricity, simultaneously with price lower carbon steel or low, medium alloy steel replacement high-alloy steel, satisfying under the actual prerequisite of using, significantly reduce cost, and combination property also is improved.
Description
Technical field
The present invention relates to a kind of hardware ﹠ tools, specifically a kind of grinding tool, especially a kind of processing technology of double metal grinding hardware tool.
Background technology
Many in the market hardware ﹠ tools mainly adopt integrated design, as drill bit, the polishing first-class, be that shank and operate portions all adopt a kind of material (mainly being carbide alloy or tool steel), because the especially rise in price of alloy of raw material, and the reduction of the profit margin of hardware ﹠ tools own (not long ago, the refund policy tax refund rate that country newly issues this reduces greatly, and might cancel the refund policy gradually), substitute the requirement that carbide alloy can not satisfy actual use and use other material instead, make manufacturer face adverse conditions.And adopt bimetallic is that shank adopts different metal or alloy with operate portions, and finished product can not satisfy the real work requirement because processing technology does not pass a test again.
Summary of the invention
At above-mentioned existing problems, the invention provides a kind of double metal grinding hardware tool processing technology, shank adopts different metal or alloy with operate portions, and handle by special process, can satisfy real work, can significantly reduce cost again simultaneously, and combination property also be improved.
In order to reach above purpose, the present invention takes following technical scheme, a kind of double metal grinding hardware tool, comprise shank and operate portions, its manufacture craft comprises shank procedure of processing, operate portions procedure of processing and welding step, it is characterized in that: described welding step is earlier shank and operate portions after handling through processing to be heated pressurization welding behind the arrival melt temperature separately respectively.
Of the present inventionly further be optimized for: in welding process, feed protective gas to prevent the oxidation of material, protective gas is reproducibility or inert gas, is specially hydrogen, nitrogen, argon gas.
Because the present invention has taked above technical scheme, operate portions adopts different metal ingredients with shank, and melt soldering by the special process electricity, simultaneously with price lower carbon steel or low, medium alloy steel replacement high-alloy steel, satisfying under the actual prerequisite of using, significantly reduce cost, and combination property also is improved.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment one
A kind of double metal grinding hardware tool, comprise shank and operate portions, the Main Ingredients and Appearance of described shank is a steel, the present invention mainly adopts carbon steel or steel alloy, steel alloy mainly comprises low-alloy steel and medium alloy steel, general is high-alloy steel (with the operate portions integral production) in the market---carbide alloy, the Main Ingredients and Appearance of described operate portions are that carbide alloy comprises tungsten carbide (WC), titanium carbide (TiC), ramet (TaC) and niobium carbide (NbC) alloy.
The processing technology of above-mentioned double metal grinding hardware tool comprises that shank procedure of processing, operate portions procedure of processing and welding step are specially:
The shank procedure of processing---utilize machining tool that shank is shaped;
The operate portions procedure of processing---utilize the operate portions forming tool to shape;
Welding step---treated shank and operate portions are heated respectively simultaneously (adopting Electric heating usually), heating sequence can before can after, heating-up temperature basis composition separately, pressurize after requiring shank and operate portions to heat arrival melt temperature separately simultaneously, ooze mutually after shank and operate portions metal alloy are melted and dissolve each other, reach the cooling back purpose of welding naturally, the method welding fastness is very high.Usually also in addition gas shield in the process of welding to prevent shank and operate portions material oxidation, influences its performance, and protective gas is reproducibility or inert gas, is specifically as follows hydrogen, nitrogen, argon gas etc.
Embodiment two
With a kind of double metal grinding hardware tool of embodiment one, its difference is: described operate portions is grinding head (also can be drill bit, cutter head).
The present invention is applicable to the hardware ﹠ tools (various grinding heads, fluted drill, dental drill, little brill, various tool cutter) of all size and model, adopt processing technology of the present invention after, can guarantee the welding fastness, and processing cost is low, outward appearance is beautiful simultaneously.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
