Description

Technical Field

[0001] The present invention relates to the technical field of diamond wire saw production, and particularly relates to a wire saw pre-twisting device. Background Art

[0002] Diamond wire saws have been widely used in stone quarrying, special-shaped cutting, and building component cutting. During the cutting process of diamond wire saws, the beads will naturally wear. After a certain period of use, the cutting efficiency will decrease until it has to be discarded. Sometimes, serious uneven wear of the beads will occur, and they have to be scrapped in advance. The uneven wear phenomenon means that during the use of diamond wire saws, the beads do not wear evenly along their circumferential surfaces, but only one side of the beads wears, resulting in serious wear on one side of the beads, even wearing down to the steel wire rope and falling off, while the other side wears less and remains relatively intact, which greatly shortens the service life of diamond wire saws. To solve the problem of uneven wear, factories generally pre-twist the produced wire saws to a certain extent, that is, pre-twist. Usually, before using diamond wire saws, the steel wire rope is pre-twisted 1.5 to 4 turns per meter, and then the two ends of the wire saw are connected. By this method, a certain amount of pre-twisting internal force is stored in the steel wire rope. During the use process, when the diamond wire saw rotates around the large guide wheel (flywheel) of the wire saw machine, the steel wire rope will rotate around its axis under the drive of the pre-twisting internal force, driving the beads to rotate, so as to achieve uniform wear and avoid uneven wear, which affects the service life of the wire saw. When factories pre-twist wire saws, most still rely on manual operation by workers. Manual pre-twisting is slow, inefficient, and the feel of each worker is different, and it is also impossible to ensure that the pre-twisting degree of the wire saw is the same each time the pre-twisting operation is performed, resulting in unstable product quality. Summary of the Invention

[0003] The object of the present invention is to provide a wire saw pre-twisting device to solve the above problems, which can conveniently and quickly complete the pre-twisting work of the wire saw and can more accurately control the pre-twisting degree of the wire saw.

[0004] The technical solution of the present invention to solve the above problems is: a wire saw pre-twisting device, including a frame, a twisting device, and a driving mechanism; a horizontal workbench is provided on the frame; the driving mechanism is arranged on the workbench, the driving mechanism is connected to the twisting device, and can drive the twisting device to rotate; the twisting device is a cylinder, and the connection point between the twisting device and the driving mechanism is arranged on its axis.

[0005] Further, the driving mechanism includes a motor, a transmission shaft, and a bearing block. The transmission shaft is installed on the workbench plane through the bearing block. There are two bearing blocks, one installed near the motor in the driving mechanism, and the other installed on one side near the torsion device. The motor is connected to the transmission shaft and drives the transmission shaft to rotate. The motor and the transmission shaft are driven by gears or by a belt. Preferably, the motor is a stepping motor and is driven by gears with the transmission shaft.

[0006] Further, the torsion device is circular, and its center coincides with the connection point, so that the center of gravity is relatively stable when the torsion device rotates.

[0007] Further, a pressing device for fixing one end head of the wire saw is provided on the torsion device. Preferably, the pressing device is arranged on the circumference of the distribution circle of the limit rods, which is beneficial for visually observing the number of turns of the wire saw winding and is also more convenient for calculation.

[0008] Further, the other end of the transmission shaft is detachably connected to the torsion device, and the connection position is the aforementioned connection point, and the transmission shaft and the torsion device are coaxial.

[0009] Further, there can be multiple torsion devices, and the diameters of the cylinders of each torsion device are different. When in use, different torsion devices can be installed according to needs to achieve different degrees of pre-twisting of the wire saw.

[0010] Advantages of the present invention: The device of the present invention can conveniently and quickly complete the pre-twisting work of the wire saw, and can more accurately control the degree of pre-twisting of the wire saw by controlling the number of turns of the wire saw wound on the torsion device; the entire wire saw pre-twisting device has a simple, compact structure and low cost.
