Detailed Description
The principles and features of the present invention are described below with examples given for the purpose of illustration only and are not intended to limit the scope of the invention.
Example 1
A brazed diamond beaded rope saw provided with a cooling channel, as shown in fig. 1-4, comprises a beaded 1 and a steel rope 2; the bead 1 comprises a matrix 3, wherein the inside of the matrix 3 is connected with a steel rope 2 in an adaptive manner by arranging a gluing filler 101, two ends of the matrix 3 are arranged as working ends, a diamond cutting layer 102 is arranged on the working ends, and the diameter of the middle part of the matrix 3 is smaller than that of the working ends to form a cooling channel. Two working ends are respectively arranged on the front end face and the rear end face of the steel matrix 3, one to multiple layers of diamonds are axially coated on the working ends by adopting a brazing process, the number of axial diamonds in a diamond cutting layer at an edge is larger than that of axial diamonds in a diamond cutting layer at a non-edge, so that the wear resistance at the edge is improved, and the polygonal deformation resistance is realized; as the diamond cutting layer 102, the binding agent has a degree of axial embedding of the front and rear diamond of 100% or more; the middle section of the base body 3 is reduced in diameter, the base body 3 is provided with two working ends, and a cooling channel is formed between the two working ends, so that the effect is greatly improved, the diamond abrasion rate is reduced, the channel simultaneously plays a role in containing scraps, the axial chip removal distance is greatly shortened, the friction resistance and the abrasion of the scraps to the bonding agent are reduced, the requirements on the compactness (related to holding force) of the bonding agent and the strength of a steel wire rope are indirectly reduced, and the development of the wire saw to the small diameter is facilitated. Solves the problems that the prior brazing method limits the small diameter development of the bead 1 and has short service life.
For a small-diameter rope saw, single-layer diamond can be adopted to reduce the requirement on the strength of the steel wire rope and the breakage rate of the steel wire rope; for the case where the strength of the wire rope is sufficient, axial multi-layer diamond may be used to increase the lifetime, which is not required to increase the diameter (i.e. increase the radial thickness of the diamond layer), and good yield may be achieved.
The glue filling may be a conventional adhesive, binder, such as a rubber adhesive layer or a rubber filling layer, etc.
The chip is removed rapidly, the requirement on the exposed height of the diamond is reduced, the selection of relatively finer diamond is facilitated, the negative effect of single diamond in the passivation state can be reduced, and the self-sharpening property of the bead 1 is facilitated to be improved.
The diamonds with the cutting edges participating in work are positioned on the end surfaces at the same time, and the circumferential intervals of the diamonds are small, so that the parts of the workpiece which are not sawed by the diamonds are in a convex state, more or less of the workpiece can be mechanically crushed without cutting, the work load of the diamonds is greatly reduced, and the service life of the beads 1 is prolonged and the cutting load is reduced.
Because the diamond is concentrated in the same axial position of the end face, the diamond layer concentration is high, the circumferential spacing between the diamond is short, and the diamond circumferential directions are orderly arranged to form the decomposition of the torsion force, the influence on the diamond falling caused by the circumferential rotation of the rope saw is greatly reduced, the integral concentration of the diamond is reduced, the requirement on the compactness of the bonding agent (related to the holding force) is reduced, the sawing load of the rope saw is reduced, and the design and manufacture of the small-diameter bead 1 are facilitated.
Example 2
In this embodiment, as shown in fig. 5-7, an intermediate inlet working end 6 is added, in order to better complete the cutting operation, the intermediate inlet working end 6 is disposed between the inlet working end 4 and the outlet working end 5, the intermediate inlet working end 6 is configured as a regular polygon having an edge combined with a plane, and the edge of the intermediate inlet working end 6 is not in the same straight line with the edge of the inlet working end 4.
In practical applications, the beads 1 may be designed in a desired shape. As shown in fig. 8, for example, the inclined body 301 and the middle inlet working end 6 may be designed according to requirements, and in addition, the inlet working end 4 and the outlet working end 5 may be provided with regular polygons.
Example 3
In this embodiment, as shown in fig. 2 and 6, in order to strengthen the substrate 3, the inlet working end 4, the outlet working end 5 and the side of the intermediate inlet working end 6 far from the diamond working layer on the substrate 3 are provided with inclined bodies 301. The outlet working end 5 is covered with a diamond cutting layer 102 at the rear end in the rope saw cutting movement direction. The diamond cutting layer 102 on the outlet working end 5 is provided on the inner side of the rear end face substrate 3 to back the steel substrate 3, thereby reducing the requirement of the bonding force between the brazing layer and the substrate 3. The front ends of the inlet working end 4 and the middle inlet working end 6 in the rope saw moving direction are covered with a diamond cutting layer 102. The diamond-cutting layer 102 density of the inlet working end 4 is greater than the diamond-cutting layer 102 density of the outlet end. The formulation parameters of the front end cutting layer and the rear end cutting layer can be different, the front end has higher shock resistance, and the diamond granularity can also be different.
Example 4
The diamond bead manufactured by the prior brazing technology has a single-layer or impregnated (multi-layer) working layer. The bead string 1 is a revolution body of a bus, and most buses are straight lines; the small number of generatrix is a curve, or a straight line plus curve, or a revolving body with a sectional curve. In the use process, the front end and the rear end of the bead string 1 are connected in a straight line in a supposition mode, and the connecting line is used as a revolving body, so that the diameter of each point in the axial direction is smaller than the diameter of the connecting line, and the bead string can be used as a space for containing scraps and introducing water in the use process.
When the rope saw works, the bead 1 moves axially and cuts on one hand, namely, is axially stressed; on the one hand, radial feeding, namely radial stress is realized; meanwhile, due to preset rotation stress, the device is stressed circumferentially. As for the impregnated beads 1, the whole circumference diamond working layer is difficult to be uniform and equal in thickness, so that the circumference is not consumed equally, the part which is consumed quickly is closer to the axle center, and is easier to be turned automatically for preferential use, so that the deflection is larger and larger, the beads 1 are insufficient to be used and fail, and the service life is greatly shortened.
When the bead string 1 is cut, the binding agent holding diamond particles is worn out faster at the front part and two sides of the particles, trailing effect, namely better supportability, is arranged at the rear part, and the diamond has a certain exposure height so as to ensure that a workpiece can be carved, and meanwhile, the bead string also has a exposure height space so as to realize chip/water containing, but the higher the exposure height is, the worse the capability of resisting damage to diamond falling caused by circumferential tangential force is.
When the bead 1 is cut, the contact section of the bead 1 and a workpiece is in an arc shape, the arc-shaped contact section has the macroscopic centering effect, but the rotation of the bead 1 is difficult to limit, and the rotation is beneficial to the balanced consumption of the bead 1 when the bead 1 is in a normal shape, and the diamond is subjected to the action of circumferential tangential force, so that the diamond is one of the largest stress sources causing unnecessary falling of the diamond, and is one of key factors causing unnecessary shortening of the service life of the bead 1.
When the bead 1 is cut, after the bead 1 is deformed, the abnormal circumferential stress rotates more frequently and is far greater than the preset internal stress circumferential stress of the rope saw, and the consolidation structure of the bead 1 fixed to the steel wire rope is also stressed greatly, so that the bead 1 is one of the largest stress sources for loosening the bead 1; the loosening of the bead 1 causes friction between the inner diameter of the bead 1 and the steel wire rope, so that the rope saw breaks the rope, which is one of the key factors affecting the service life of the rope saw.
The diamond beads 1 of the prior brazing technology are arranged on the outer diameter circumferential surface of the ring of the matrix 3, have various structural shapes, and the whole life of the rope saw of the single-layer brazing bead 1 is short; at present, more and more impregnated (multi-layer) brazing modes with various structural shapes are adopted, because of the string beads 1 in a brazing mode, the diamond holding force is strong but the self-sharpening property is relatively poor, in order to improve the self-sharpening property and ensure the service life, the capability of holding the diamond by brazing needs to be reduced, and meanwhile, thicker diamond working layers are selected, so that the development of the small diameter of the string beads 1 is limited; the length of the bead 1 is increased, the service life can be prolonged, but the flexibility of the rope saw is reduced, and the bead 1 is easy to be wound instantly when entering a workpiece, the fatigue strength of a steel wire rope is damaged, and the rope breakage rate is increased. The front end in the rope saw cutting movement direction is an inlet working end 4, the tail in the rope saw cutting movement direction is an outlet working end 5, the inlet working end 4 is a regular polygon with edges combined with a plane, and the outlet working end 5 is a cylinder. The diameter of the outlet working end 5 is not smaller than the diameter of the circumcircle of the inlet working end 4. The outer edge profile of the front end cutting layer in the rope saw cutting movement direction is regular polygon, the outer edge profile of the rear end cutting layer is circular, the diameter of the rear end cutting layer is larger than or equal to the diameter of the front end cutting layer circumscribed circle, the rear end cutting layer can play a role in optimizing the surface quality of a workpiece, and the front end cutting layer of the next bead string 1 can work in a high pressure mode. Ensure that the sharp angle has more diamonds to keep the shape, and the edge on the inlet working end 4 is provided with a rounding angle.
The rotating amplitude of the bead 1 with the polygonal front end cutting layer is limited during cutting; when the polygonal beads 1 leave the workpiece, the polygonal beads are free to rotate, so that the used positions are in a random state, the peripheral surface of the diamond working layer of the polygonal beads 1 is guaranteed to be uniformly worn, even if the peripheral surface of the diamond working layer is worn out in an unbalanced mode, further unbalance can not be accelerated, negative influences on diamond falling caused by circumferential tangential force are avoided or reduced, the diamond concentration is reduced, the diamond etching pressure intensity can be increased, the sharpness is improved, and the diamond cost is reduced.
The angles of the polygonal beads 1 when each polygonal bead 1 enters the workpiece are random, so that the probability that the cutting surfaces of the front and rear polygonal beads 1 are not coincident when cutting is extremely high, the contact area between the polygonal beads 1 and the workpiece is reduced, the pressure intensity of the polygonal beads 1 when cutting is increased, and diamond cutting is facilitated, namely the cutting efficiency is improved; the characteristics also provide space for increasing the diamond concentration, and can improve the service life of the polygonal beads 1; this phenomenon also provides favorable conditions for chip holding/cooling, and is favorable for reducing the heat loss of the diamond and maintaining the cutting edge angle, namely prolonging the service life and improving the sharpness.
