Abstract
The present invention is one kind of diamond rope saw bead string with equiwear carcass structure, and the equiwear carcass structure has axially gradually weakened wear resistance from front end to back end. Specifically, the bead string may have axial sectional beads, in which the sections have gradually decreased carcass hardness and/or gradually decreased diamond concentration from the front section to the latter section; stepped beads, in which the bead carcass diameter decreases gradually from front section to latter section; or back taper beads, in which the bead carcass diameter decreases gradually to form a cone of 5-20 deg, preferably 8-16. The present invention has homogeneous wear of beads, 20 % raised work efficiency and 30 % over increased rope saw life.
Description
(1) technical field:
The present invention relates to a kind of diamond rope saw beading structure, be specifically related to the diamond rope saw beading of abrasion carcass structures such as having.
(2) background technology:
Diamond rope saw is with the linear velocity motion of 20-30 meter per second in sawing process and cuts in the material (stone material or concrete etc.), every beading front end load that all will have certain impact, therefore beading front end is than the rear end quick abrasion, beading carcass forms uneven wear, work later stage beading are big cone-shaped in the little rear end of front end, and this not only influences the life-span and the efficient of rope saw, and wear and tear too early because of front end, cause steel rope abrasion to fracture, whole rope saw is scrapped.The present diamond rope saw that in heterotype profiled sheet processing or material mine exploitation, uses, often be beading as yet wearing and tearing put in place, just scrap and can't use.
(3) summary of the invention:
In order to give full play to the usefulness of diamond bead, the present invention proposes the new mentality of designing of abrasion such as beading carcass, take measures from aspects such as carcass structure, diamond concentration proportionings, solve beading effectively and effectively wait the abrasion problem, thereby improve the life-span and the service efficiency of diamond rope saw.
The technical scheme that realizes foregoing invention is a kind of beading of design, and its carcass has waiting of weakening gradually from front end to the rear end abrasion resistance and wears away structure.Specifically can be:
1. axial segmentation formula beading
1) structural design
The segmentation vertically of beading carcass, can divide two sections, three sections or more, each segment length can be the same or different, from leading portion backward the section, every section is selected the matrix formula of different hardness that tyre body hardness is descended piecemeal, perhaps every section diamond that adopts variable concentrations even diamond concentration reduces piecemeal, or adopts aforementioned two kinds of methods simultaneously.
2) principle Analysis
When working according to general beading, the front end wearing and tearing are big, the little characteristics of rear end wearing and tearing, and we adopt the method for different tyre body hardness in front and back end and different diamond concentrations.For example in same prescription, front end is selected the diamond concentration of 60-80% for use, the rear end is selected the diamond concentration of 30-50% for use, just beading front end manys the diamond concentration of 20-30% than the rear end, obviously the diamond concentration height ratio is more wear-resisting, remove to bear the unfavorable conditions such as frequent impact that front end runs into the diamond that has more 20-30% concentration, in the hope of reaching the effect of wearing and tearing with backend synchronization.In like manner, beading front end high rigidity carcass is more wear-resisting than the rear end, can reach the effect of synchronous wearing and tearing equally.
2. multiple stage type beading
The segmentation vertically of beading carcass, from leading portion section backward, the diameter of beading carcass is step-like and reduces piecemeal, can be two stage steps, three grades of steps or more, and distance can equate or do not wait between the step.
3. desk-top beading of back taper
1) beading structure
Beading carcass is the inversed taper platform shape that diameter dwindles gradually to the back-end from front end, and tapering is generally 5-20 °, is preferably 8-16 °.
2) principle Analysis
It is big that common beading present the front end wearing and tearing at work, the rear end wearing and tearing are little, be cone-shaped after work a period of time, promptly the little rear end of front end is big, therefore on structural design, act in a diametrically opposite way, it is desk-top to have a mind to be designed to the little back taper in the big rear end of front end, and the leading portion diameter is big like this, and is wear-resisting, can control the size of tapering according to rock behavio(u)r, to reach the purpose of equivalence abrasion.
Multiple stage type beading only are the mould structure differences therewith in like manner.
The desk-top beading of back taper and multiple stage type beading also can adopt axial segmentation formula beading structural design simultaneously, be beading carcass vertically from leading portion backward the section, every section is selected the matrix formula of different hardness that tyre body hardness is descended piecemeal, perhaps every section diamond that adopts variable concentrations, even diamond concentration reduces piecemeal, or adopt aforementioned two kinds of methods simultaneously.
Design of the present invention has solved beading uniform wear at work, increases work efficiency more than 20%, and the life-span that increases the rope saw is more than 30%.
(4) description of drawings:
Fig. 1 is a kind of embodiment structural representation of axial segmentation formula beading of the present invention;
Fig. 2 is the another kind of embodiment structural representation of axial segmentation formula beading of the present invention;
Fig. 3 is a kind of multiple stage type beading of a present invention embodiment structural representation;
Fig. 4 is the desk-top beading embodiment of a kind of back taper of a present invention structural representation.
Number in the figure is:
1, pearl core, 2, carcass.
(5) specific embodiment:
Be several non-limiting examples of the present invention below.
1, axial segmentation formula beading
Cut a granite and concrete beading for difficulty, adopt segmentation structure, generally divide two sections also can divide three sections, the front and back segment length can equate also can not wait.Adopt identical matrix formula, different diamond concentrations, better effects if is a little.
2, multiple stage type beading
Multiple stage type beading also are used for difficulty and cut rock and require long diamond rope saw of life-span.
3, the desk-top beading of back taper
No matter the processing of desk-top beading cold stamping die of back taper or carbon mould is easier than step, carcass 2 abrasion are joined in the work, meet front end and wear away the little mechanism of big rear end wearing and tearing.Tapering is neglected beading diameter, length and purposes selection greatly, generally selects 5-20 °, preferably 8-16 °.
Embodiment illustrated in fig. 43 are the granite mine finishing desk-top beading of ￠ 11mm back taper, and beading comprise pearl core 1 and carcass 2, and beading carcass 2 point diameters are 11mm, and beading length is 8mm, and the carcass tapering is 12 °.
