Abstract
The invention discloses a processing roll for a multi-wire saw capable of preventing wire fracture. The processing roll comprises a roll body of the processing roll and roll covers which are positioned at the two ends of the roll body of the processing roll as well as a rotary shaft which is positioned in the roll body of the processing roll and extends out of the roll covers, wherein the roll body of the processing roll is a double-layer hollow structure; a refrigerant fluid is stored in an inner cavity of the double-layer hollow structure; a silica gel sleeve is arranged outside the roll body of the processing roll in a sleeving mode; and the surface of the silica gel sleeve is uniformly provided with wire passing grooves. In this way, the refrigerant fluid is filled into the hollow layer of the roll body of the processing roll to reduce the surface temperature of the processing roll in high-speed rotation, so that influences of a high temperature to performances of a cut metal wire which passes through the grooves of the processing roll are reduced; meanwhile, the silica gel sleeve is arranged outside the roll body of the processing roll in the sleeving mode, and a wire passing groove is formed in silica gel sleeve, so that friction between the cut metal wire and the groove can be reduced, and therefore, a wire fracture phenomenon in a high-speed cutting process is effectively avoided.
Description
Technical field
The present invention relates to multi-line cutting machine part field, particularly relate to a kind of anti-fracture of wire multi-line cutting machine working roll.
Background technology
Multi-wire saw principle is by wire suitably tensioning, and with certain speed and pressure, reciprocating relative to the workpiece of cutting, in the process of cutting, between wire and workpiece, constantly add the cutting fluid being mixed with abrasive material, just can cut workpiece.In order to reduce the width of otch, wire generally uses tungsten filament or the steel wire of φ 0.1-0.25mm, speed wiry can up to 1000m/min, abrasive material can according to by the hardness of cut part, select carborundum, aluminium oxide and diamond, granularity is No. 150-No. 180, is mixed in machine oil, kerosene or water and uses.
The surface of multi-line cutting machine working roll is provided with groove, wire moves reciprocatingly through groove and to cut workpiece, in high-speed cutting workpiece fabrication, wire very easily causes fracture of wire phenomenon because occurring to wear and tear with working roll groove inner wall, has a strong impact on cut quality and efficiency.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anti-fracture of wire multi-line cutting machine working roll, can solve the defect that existing multi-line cutting machine working roll exists.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of anti-fracture of wire multi-line cutting machine working roll, comprise: working roll roll body and be positioned at the roller lid at described working roll roll body two ends and be positioned at described working roll roll body and extend to the rotating shaft outside described roller lid, described working roll roll body is double layer hollow structure, refrigerating fluid has been deposited in its internal cavity, be set with silica gel sheath cylinder outside described working roll roll body, uniformly offer line groove at described silica gel sleeve.
In a preferred embodiment of the present invention, described line groove is excessively semi-circular structure.
In a preferred embodiment of the present invention, the internal diameter of described line groove is excessively slightly larger than wire diameter, and groove inner wall described in line is coated with lube layer excessively.
The invention has the beneficial effects as follows: working roll roll body of the present invention is double layer hollow structure, refrigerating fluid is filled with in its hollow layer, the working roll surface temperature of High Rotation Speed can be reduced, thus reduce high temperature to the performance impact of the Metal Cutting silk in working roll surface groove, be set with silica gel sheath cylinder outside working roll roll body simultaneously, crossing line groove is opened on silica gel sleeve, can reduce the friction between Metal Cutting silk and groove, thus effectively avoids the fracture of wire phenomenon in high-speed cutting process.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's anti-fracture of wire multi-line cutting machine working roll one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, working roll roll body, and 2, roller lid, 3, rotating shaft, 4, refrigerating fluid, 5, silica gel sleeve, 6, cross line groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of anti-fracture of wire multi-line cutting machine working roll, comprise: working roll roll body 1, be welded on described working roll roll body 1 two ends roller lid 2, be arranged in described working roll roll body and the rotating shaft 3 extended to outside described roller lid 2, described working roll roll body 1 is double layer hollow structure, refrigerating fluid 4 has been deposited in its internal cavity, this refrigerating fluid 4 can effectively reduce the temperature that in high-speed rotation process, working roll roll body 1 distributes, be set with silica gel sheath cylinder 5 outside described working roll roll body 1, uniformly offer line groove 6 at described silica gel sleeve 5.
Preferably, described line groove 6 of crossing is in semi-circular structure, and its internal diameter is slightly larger than wire diameter, and described line groove 6 inwall of crossing is coated with lube layer, and the frictional force making this cross between line groove 6 and cutting metal wire is little.
Present invention is disclosed a kind of anti-fracture of wire multi-line cutting machine working roll, working roll roll body is double layer hollow structure, refrigerating fluid is filled with in its hollow layer, the working roll surface temperature of High Rotation Speed can be reduced, thus reduce high temperature to the performance impact of the Metal Cutting silk in working roll surface groove, be set with silica gel sheath cylinder outside working roll roll body simultaneously, crossing line groove is opened on silica gel sleeve, the friction between Metal Cutting silk and groove can be reduced, thus effectively avoid the fracture of wire phenomenon in high-speed cutting process.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
