Further, the shaft sections of the first supporting roller 3, the second supporting roller 4 and the third supporting roller 5 are arranged in an inverted triangle, and the third supporting roller 5 is arranged right below the symmetrical shaft positions of the first supporting roller 3 and the second supporting roller 4. The third supporting roller 5 is arranged right below and connected with the first supporting roller and the second supporting roller to form an inverted isosceles triangle structure, the structure is symmetrically arranged, the yielding space is increased to the maximum extent, the size of the three supporting rollers is limited, and the cutting range with the maximum size is realized through the most compact structural design.
Further, a bearing box 6 for supporting the rotation of the roll shafts is fixed on the frame 1, and the two ends of the first support roller 3, the second support roller 4 and the third support roller 5 are all rotationally fixed inside the frame 1 through the bearing box 6.
Furthermore, the first supporting roller 3, the second supporting roller 4 and the third supporting roller 5 are respectively provided with a wire groove for limiting a diamond wire.
Example 2
As shown in fig. 2, a three-roller wire saw device has the same structure as the embodiment of example 1, except that:
the wire web 2 between the first support roller 3 and the second support roller 4 forms a cutting zone below which a chip box 7 for receiving chips of cut material is arranged.
Further, the chip box 7 is disposed above the third supporting roller 5 with its opening upward.
Further, a chip box 7 is provided between the first support roller 3 and the second support roller 4.
The outer diameters of the first supporting roller 3 and the second supporting roller 4 are equal, the radiuses of the first supporting roller 3 and the second supporting roller 4 are both R, the axial distance between the first supporting roller 3 and the second supporting roller 4 is L, the radius of the third supporting roller 5 is R, and the vertical distance from the axis of the third supporting roller 5 to a top cutting area is H. In the actual production process, the actual cutting capacity of the wire saw is mainly related to the width of a wire mesh 2 of a cutting area, the size of a silicon rod is required to be less than L-2R-x, and the size of the silicon rod is required to be less than H-R-x, wherein x is an empirical constant, and the value range of x is 8-30 mm. The first supporting roller 3 and the second supporting roller 4 mainly determine the width L of the wire net 2, and the third supporting roller 5 mainly plays a role of supporting the wire net 2 to determine the height H of the wire net 2. Therefore, the smaller the width of the distance web 2 between the first and second support rollers 3 and 4, the smaller the size of the material that can be cut, and the larger the width of the web 2 between the first and second support rollers 3 and 4, the larger the size of the material that can be cut. The width of the wire mesh 2 of the first supporting roller 3 and the second supporting roller 4 also influences the cutting quality, when the size of the material is smaller, the smaller the width L of the wire mesh 2 is, the better the rigidity of the diamond wires fully distributed on the supporting rollers is, the better the cutting yield is, and as the width L of the wire mesh 2 is increased, the rigidity of the steel wires fully distributed on the cutting rollers is reduced, and the yield is correspondingly reduced, so that under the condition of meeting the size of the cut hard and brittle material, the smaller the center distance L is, the better the cutting quality is. However, in the actual cutting process, the diamond wire needs a certain linear velocity and the capability of overcoming the cutting resistance to ensure the cutting efficiency, so that the motor for driving the main roller must have a high rotating speed, and the motor is required to output a large torque to have the corresponding cutting capability. The conventional slicer is commonly used with a servo motor, and when the rated torque is large, the rated rotating speed is lower; when the rated torque is small, the rated rotating speed is high. Because of the characteristics of the rotating speed and the torque of the motor, the maximum roller motor determines the final cutting linear speed of the diamond wire slicer, and the small roller motor plays a following role. Therefore, the diameter of the third support roller 5 is limited to 150-300mm, and the proper optimal values of the rotating speed and the torque value of the large roller motor can be ensured. The outer diameter of the first support roller 3 or the second support roller 4 is suitably smaller than the outer diameter of the third support roller 5 by 0 to 150mm, preferably 0 to 100mm, more preferably 0 to 50 mm.
Through parallel arrangement's three backing rolls, compare common two roller coping saw devices, increased fore-and-aft space of stepping down for waiting to cut the piece and can cutting the darker length downwards in the cutting district, reduced the restrictive condition that the piece size was treated to the coping saw device, increased the cutting depth of coping saw, improve single cutting production efficiency, reduce the cutting number of times that waiting to cut the piece with similar size, improve the utilization ratio of buddha's warrior attendant line, reduction enterprise manufacturing cost. Bearing box 6 sets up at the both ends of every backing roll for fix the backing roll on frame 1, and make the backing roll can rotate under the drive of motor, bearing box 6 is connected with the backing roll is detachable, conveniently maintains or changes the backing roll.
Through setting up two backing rolls of smaller size side by side, when guaranteeing the cutting effect, increase the space of transversely stepping down to increase cutting area as far as is favorable to cutting wider work piece of waiting to cut. The layout mode of two small and large supporting rollers enables the structure of the fretsaw to be more compact, the distance between the first supporting roller 3 and the second supporting roller 4 is utilized to the maximum extent, meanwhile, the small-sized supporting rollers can save production materials of the supporting rollers, and the production cost of enterprises is reduced.
When the wire saw device cuts a hard and brittle material, due to the hard and brittle characteristics of the material, edge breakage or slag falling can occur in the cutting process, the falling fragments are easily adhered to the third supporting roller 5, and the fragments adhered to the third supporting roller 5 can rotate to the contact area of the wire net 2 along with the rotation of the third supporting roller 5, so that the wire net 2 is easily cut off by the fragments, and the normal operation of the cutting process is influenced. Through setting up fragment box 7, catch the piece that drops from the cutting area among the cutting process to avoid the piece to cut off the condition of gauze 2 and take place, inside fragment box 7 is detachable to be fixed in gauze 2, better receipt piece conveniently takes off the clearance after the cutting process finishes simultaneously. The fragment box 7 is arranged between the first supporting roller 3 and the second supporting roller 4, so that the cutting process of the workpiece to be cut is completely carried out in the fragment box 7, and the fragments generated in the cutting process are prevented from splashing to the first supporting roller 3 and the second supporting roller 4 on two sides to cause the wire net 2 to be broken. The opening area of the fragment box 7 is larger than the area of the actual cutting area, so that all fragments generated in the cutting process are ensured to be received.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
