[0025] Working process of the present invention:

[0026] During the working process of the automatic connection for long material sawing of a high-speed metal circular sawing machine of the present invention, the feeding device 1 feeds the bar material into the high-speed metal circular sawing machine 2 for sawing. The sawn bar material is conveyed to the material receiving device 4 through the material pulling device 3.

[0027] When the material pulling device 3 is working, when the bar stock entering the front material receiving mechanism 322 is short bar stock, the short bar stock is pulled into the rear material receiving mechanism 323 by the material pulling assembly 34. Then, the hydraulic cylinder II 3231 drives the mounting seat 3235 to rotate, making the mounting seat 3235 in an inclined state. At this time, the bar stock resting on the roller 3233 and the material guiding seat 3234 rolls into the material guiding body 3243 and then into the material frame; when the bar stock entering the front material receiving mechanism 322 is long bar stock, the long bar stock is pulled into the material turning device 33 by the material pulling assembly 34. Then, the hydraulic cylinder IV 332 drives the material turning support plate 331 to rotate into an inclined state. At this time, the bar stock resting on the material guiding body 333 and the rotating roller 334 rolls into the material receiving device 4.

[0028] When the material pulling assembly 34 is working, the clamping seat clamps the bar stock by driving of the hydraulic cylinder III. Then, the driving motor drives the gear to rotate, and the gear meshes with the rack to drive the mounting slide to move. The mounting slide drives the hydraulic cylinder III to move through the seat body. The hydraulic cylinder III drives the bar stock clamped by the clamping seat into the rear material receiving mechanism 323 or the material turning device 33 through the clamping seat.

[0029] When the adjusting support device needs to be adjusted upward, the nut body 2221 is rotated clockwise to be loosened and drives the pin 2224 to rotate. When the pin 2224 moves to the end of the arc-shaped groove 2223 and is blocked, it will drive the T-shaped sleeve body 2222 to rotate. The T-shaped sleeve body 2222 drives the second T-shaped nut 224 to rotate together through the cooperation of the opening groove 223 and the plug-in body 225. Since the second T-shaped nut 224 needs to move downward while rotating, but the second T-shaped nut 224 is blocked and cannot move downward, it will drive the screw body 221 to move upward. The screw body 221 drives the shock absorption mechanism 21 to rise. After the adjustment is completed, the nut body 2221 is tightened;

[0030] When the adjusting support device needs to be adjusted downward, the nut body 2221 is rotated clockwise to be loosened, and then the second T-shaped nut 224 is rotated counterclockwise. The second T-shaped nut 224 drives the T-shaped sleeve body 2222 to rotate through the cooperation of the opening groove 223 and the plug-in body 225. The T-shaped sleeve body 2222 drives the nut body 2221 to rotate together through the cooperation of the arc-shaped groove 2223 and the pin 2224. Since the nut body 2221 moves upward while rotating counterclockwise, and the nut body 2221 is blocked and cannot move upward, it will drive the screw body 221 to move downward. The screw body 221 drives the shock absorption mechanism 21 to descend. After the adjustment is completed, the nut body 2221 is tightened.

[0031] When the feeding device 1 works, the pushing oil cylinder 112 pushes the connected swing arm 17 to swing. The swing arm 17 drives other swing arms 17 to swing through the cooperation of the sliding body 110 and the connecting rod 19. The swing arm 17 drives the stock pushing plate 16 to turn 90 degrees. The stock pushing plate 16 lifts the bar near the material blocking body 113. Since the working end of the stock pushing plate 16 is an inclined surface, the lifted bar rolls along the working end of the stock pushing plate 16 into the supporting roller 15 and the feeding table of the high-speed metal circular sawing machine 2.

[0032] The above embodiments are illustrative of the present invention, not limitations thereof. Any simple transformation of the present invention falls within the protection scope of the present invention.
