Background technique
Lathe is mounted on fixture during processing, by the relative motion of cutter and fixture, while with tool sharpening
On workpiece.But this process not necessarily machining, it is also possible to pressure processing (such as annular knurl is carried out on lathe
Or spinning).In this process, machine tool guideway face played an important role.But machine tool guideway face is in the work of lathe
In the process, it will cause the case where plucking scratches due to various reasons.It is very serious to be, if cannot timely repair, draw
Hurting scored surface can rapidly expand, and finally result in entire guide pass and be destroyed, and the serious precision for having influenced lathe and set
Standby serviceability rate.
The method of traditional renovation machine guide pass is the method for surfacing or arc welding.(1) in the repair process of surfacing
In, it needs for the preheating face of guide rail to be heated to 150 degree or more, after the spraying for completing preliminary welding powder, spray-coating surface is heated to 900-
1200 degree or more, burnishing surface is formed after melting welding powder.But the time that this process heats and preheats is long, workpiece heating surface area
Greatly, thermal stress is big, is very easy to crack, at the same linear shrinkage crack tendency it is bigger.(2) in the repair process of arc welding
In, cylinder iron welding rod Z248 carries out soldering by corresponding technique, and process for welding repair is divided to two kinds, the first: weld preheating is to 550 DEG C -650
DEG C when carry out soldering, keep the temperature 5-8 hours, second after soldering: workpiece weldering before does not preheat, postweld heat preservation 3-4 hours.Two methods
Quality of welding repair be not easy to guarantee, easy cracked, hard spot is not easy to be machined after soldering.
Traditional surfacing the disadvantage is that obviously, be first it is very easy cracked in this process, workpiece is heated
It is easily deformed and secondary blowhole.This is also the basic original that traditional process for welding repair cannot thoroughly solve machine tool guideway defect repair
Cause.In addition, traditional process for welding repair is not suitable for the reparation of visible machined surface, it is suitable for non-processing face or invisible machined surface
Reparation.Meanwhile in the mending course, quality of welding repair is not easily controlled, and needs the technology of operator and experienced.

This characteristic makes the material enormously simplify operation in for the coating after heating, and is easy to use.
Summary of the invention
The purpose of the present invention is to overcome the deficiency in the prior art, provides a kind of room temperature liquid for renovation machine guide pass
State metal and its processing technology.The material not only has extremely excellent binding force with matrix ferroalloy, when in coating procedure
Big range of temperature in have more constant solid-liquid two-phase proportion.This characteristic makes the material after for heating
Coating in enormously simplify operation, be easy to use.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of room temperature liquid metal and its processing technology for renovation machine guide pass.By weight percentage, the alloy
Group becomes Nb:2.0-3.0wt.%, Fe:1.0-1.5wt.%, In:4.0-6.0wt.%, Sb:8.0-10.0wt.%, Ge:0.5-
0.8wt.%, Mn:0.2-0.5wt.%, Ni:1.0-2.0wt.%, surplus are tin.
Above-mentioned a kind of room temperature liquid metal and its processing technology for renovation machine guide pass, including following processing
With use step :(a) by alloy according to required ingredient with postponing, be put into induction furnace and carry out melting, and using magnesia or
Person's alumina crucible carries out the melting under argon gas protection；10 minutes are kept the temperature using electromagnetic agitation sufficiently by alloy in 500-600 degree
Melt after mixing evenly, is imported in cast iron die and is cast；(b) dregs on the alloy molten solution surface melted are scraped off, is poured
Casting in the triangle metal trough at about 25 degree or so of an inclination angle reparation item.It repairs item and is about 200-300 millimeters, width is 8-10 milli
Rice, thick about 3-5 millimeters is advisable；(c) decontamination: with cotton yarn repairing position and the greasy dirt wiped clean of surrounding；Degreasing is pressed from both sides with tweezers
Cotton dips in acetone and wipes at repairing position, until cotton-wool is not in black；Electric iron with 300-350 degree or so is pulling position
Ironing one time, make to clean not clean greasy dirt evaporation in groove；(d) it derusts: dipping in pickling solution (dilute hydrochloric acid) with tweezers folder absorbent cotton and wipe
