Description

Technical Field

[0002] Band saw is a kind of sawing equipment, usually used for sawing wood, aluminum, copper, profiles and other materials. The background technology of band saw has undergone years of development and improvement. With the continuous advancement of science and technology, the sawing accuracy, cutting speed, safety and other aspects of band saw have been significantly improved. At present, band saw has been widely used in industrial production.

[0003] At present, the general production process for punching teeth of band saw materials is: first install the processed band saw material on the punching machine, and then install a single tooth die on the punching machine to open the teeth.

[0043] Specifically, the working process or working principle of this band saw CNC punching machine is as follows: first, the staff places the raw materials to be processed into the band saw on the surface of the conveyor belt 204, and then starts the motor 208.

[0044] At the same time, the rotating first double-groove pulley 209 can drive the eccentric plate 219 to perform eccentric movement, and then drive the first threaded rod 220 to slide up and down inside the first threaded cylinder 221, so as to drive the first threaded cylinder 221 to reciprocate, and the reciprocating rotation of the first threaded cylinder 221 can drive the first gear 222 to reciprocate. When the first gear 222 reciprocates, the toothed belt 224 will move reciprocatingly, so as to drive the two second double-groove pulleys 223 to reciprocate. When the second double-groove pulley 223 reciprocates, the reciprocating second double-groove pulley 223 can drive the second pulley 226 to reciprocate, and the reciprocating rotation of the second pulley 226 can drive the second threaded rod 225 to reciprocate. The surface of the second threaded rod 225 is threadedly installed with a second slider 227, which can drive the second slider 227 to slide up and down. The up and down movement of the second slider 227 allows the punching head 230 to punch teeth on the raw material of the band saw.

[0045] At the same time, the rotating first double-groove pulley 209 can drive the third pulley 303 to rotate, the rotating third pulley 303 can drive the second rotating shaft 302 to rotate, the rotating second rotating shaft 302 can drive the front second gear 304 to rotate, the rotation of the front second gear 304 can drive the rear second gear 304 to rotate in the opposite direction, the rotating second gear 304 can drive the two first half gears 307 to rotate in the opposite direction, and thus the first tooth plate 306 can slide back and forth inside the first sliding track 305, the reciprocating sliding of the first tooth plate 306 can drive the grinding head 309 to reciprocate, and thus the burrs of the band saw with completed punching teeth can be removed.

[0046] When the conveyor belt 204 moves, it can drive the toggle frame 406 to rotate, and then drive the third rotating shaft 404 to rotate. The rotating third rotating shaft 404 can drive the two second half gears 405 to rotate, and then drive the two second tooth plates 402 to perform staggered motion. When the two second tooth plates 402 perform staggered motion, they can drive the gear ring 408 to rotate. The rotating gear ring 408 can drive the two second threaded cylinders 410 to rotate in the same direction, and the rotation of the two second threaded cylinders 410 can make the internal third threaded rods 412 perform staggered motion up and down. When the toggle frame 406 rotates a certain number of circles, any one of the two third threaded rods 412 rises to a place where it can touch the control button 418, driving the hydraulic telescopic rod 419 to extend and retract up and down, thereby driving the cutting knife 423 to cut the band saw.
