Abstract
The present invention relates to a kind of rope saw string ball and its manufacturing methods.The rope saw string ball includes carcass working lining and liner body, is mainly characterized by liner body using iron-copper powder and adds a small amount of small size diamond sintering molding, is then integrated again with carcass working lining hot pressed sintering.In addition, on the inside of the liner body and concaveconvex structure is respectively set in end for the fixation convenient for rope saw string ball on a steel cord.Compare common rope saw string ball on existing market, and the wearability of the rope saw string ball liner body is stronger, and has the function of auxiliary cutting.On the one hand, it can avoid axially or radially consuming unevenness because of beading carcass working lining, be ground to liner body and steel cable quickly, carcass working lining is caused not consume the waste for completely and cutting material；On the other hand, the manufacture craft of the rope saw string ball liner body is easy, and high production efficiency and overall cost are low.The rope saw string ball has great practical value and technical advantage.
Description
Technical field
The present invention relates to a kind of rope saw string ball and its manufacturing methods, are mainly used in strong concrete and all kinds of granite
The cutting field of equal hard brittle materials.
Background technique
Diamond wire saw is as a kind of green product for stone mining and processing, with its excellent cutting
Performance is just gradually applying to concrete cutting etc..
The structure of diamond wire saw is as depicted in figs. 1 and 2, is made of a beading 1, steel cable 2, fixing sleeve 3, a beading 1 by
Carcass working lining 11 and liner body 12 are constituted, and the material of liner body is usually to be made of steel or Copper fabrication, process include vehicle, brill,
The cumbersome process such as milling, liner body also needs to do tapping processing after beading sintering, leads to comprehensive process higher cost (the about 0.3- of liner body
0.5 yuan /).Belong to soft material than liner body with the diamond phase of carcass working lining simultaneously, wearability is poor.
When using rope saw cut armored concrete, since the cutting area of single concrete beam is relatively small, generally
0.5m2Hereinafter, being different from the big face of stone material cuts (generally 20m2More than), auxiliary guide wheel can not be installed substantially, so that rope saw is cut
Track envelope very little is cut, the front end of beading carcass working lining is serious vulnerable to impact wear；In addition, rope used in cut surface is small
It is also relatively short to saw length, rope saw rotation is unsmooth, is also easy to produce rope saw string ball eccentric wear.It is not wear-resisting since the material is soft for liner body, one
The abrasion of denier part carcass working lining, liner body and armored concrete generate friction, and beading liner body and steel cable are worn quickly, and are finally led
Cause rope is sawed-off to split.It is analyzed by the actual use to rope saw, service life only has the 50-62% of projected life substantially, causes
Great waste of raw materials also in a disguised form increases the use cost of rope saw.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provide it is a kind of cost is relatively low, the longer rope saw string ball of service life and its
Manufacturing method.
The technical scheme adopted by the invention is as follows a kind of rope saw string ball, including carcass working lining and liner body, it is characterized by
Liner body is by being sintered after diamond and powder mixing.
Since liner body is by being sintered after diamond and powder mixing, main function is enhancing liner body wearability, really
The carcass working lining consumption for protecting a beading is thorough, and then improves the Acceptable life of rope saw and the utilization rate of material, while liner body
It is sintering into without machining, reduces processing cost, advantageously reduce beading overall cost.
The material of liner body forms are as follows: iron powder, copper alloy powder and diamond, wherein iron powder, copper alloy powder and diamond weight
Percentage is respectively as follows: iron powder 72-85%, copper alloy powder 10-20%, diamond 5-8%；Iron powder used is electrolytic iron powder；Copper alloy powder
For atomized powder, wherein accounting for 0-25% containing Zn, Sn accounts for 0-15%, surplus Cu；Diamond grit is 60-100 mesh.Since liner body includes
Small size diamond, wearability will greatly improve.The Novel rope saw cut time extends 10-15%, and cutting area improves
12-15%, actual life are increased to 78-85% by original 50-62%.
The present invention also carries out following improve to the structure of liner body: liner body front and rear sides designs fluted, 6-14 groove etc.
Circle distribution.Rubber or plastics etc. since liner body front and back end is equipped with groove, in rope saw injection moulding for making fixing sleeve
Packing material is embedded in groove, keeps the combination between liner body and fixing sleeve more stable, effectively prevent the loosening of liner body.
The outer diameter of liner body is 4-8mm, recess width 1.5-2.0mm, depth 1.0-2.0mm.
The design of liner body central bore has a plurality of equidistant boss.In rope saw injection moulding for making fixing sleeve
The packing materials such as rubber or plastics are embedded in the interval of boss, are kept the connection of liner body and steel cable stronger, are effectively prevent liner body
Relative rotation between steel cable.
The internal diameter of liner body is 3-5mm, boss height 1.0-1.5mm, width 1.0-1.5mm.
A kind of manufacturing method of rope saw string ball, it is characterised in that include the following steps:
1. iron powder 72-85% by weight percentage, copper alloy powder 10-20%, diamond 5-8%, add granula, granulation agent is
Iron powder, copper alloy powder and diamond total weight 2-4% carry out mixing；Iron powder used is electrolytic iron powder；Copper alloy powder is atomized powder,
0-25% wherein is accounted for containing Zn, Sn accounts for 0-15%, surplus Cu；Diamond grit is 60-100 mesh；
2. powder is uniformly mixed, the isopropanol that addition accounts for powder total weight 2-4% carries out powder pelletization；Powder granulation
After be put into cold press hopper, and be cold-pressed green body using cold stamping die compacting liner body；
3. cold pressing green body carries out once sintered molding after the completion of compacting, sintered liner body carries out surface sand-blasting and derusting
Processing；
4. in the cold pressing green body of the liner body insertion carcass working lining after surface treatment, the carcass working lining after hot pressed sintering
Together with liner body metallurgy soldering.
The step 3. in the sinter molding of liner body carried out in meshbeltfurnace, protective atmosphere is pure hydrogen or decomposed ammonia
It is 1000-1050 DEG C Deng, sintering temperature, sintering time 20-40min.
The step 4. in carcass working lining hot-pressing sintering technique are as follows: sintering temperature is 750-850 DEG C, and sintering time is
3-5min, pressing pressure 30MPa.
The other types that a compare beading, the invention has the following advantages that the liner body of the beading is that iron-copper alloy powder is primary
Sinter molding, and inexpensive diamond is included, for solving existing conventional rope saw string ball in use because of carcass working lining
Eccentric wear and taper it is bigger than normal and cause rope saw scrap in advance, it is ensured that rope saw in use carcass working lining can reach substantially completely
Consumption improves stock utilization, avoids generating material waste and increases the use cost of rope saw.In addition, simplifying a beading produces work
Skill and the production efficiency for improving a beading.
