[0001] The utility model relates to the technical field of mechanical processing, in particular to a flying saw automatic tracking cutting device. Background Art

[0002] In many fields such as industrial production, wire cutting is a common and important processing operation. Traditional wire cutting methods mainly rely on manual operation or simple semi-automatic equipment.

Fatigue may also lead to operational errors, posing a threat to workers' safety. On the other hand, manual cutting is difficult to ensure high precision and consistency of cutting length. Although semi-automatic cutting equipment has reduced the labor intensity of workers to a certain extent, it still has limitations. These devices often cannot achieve automatic tracking cutting of steel wire and require manual assisted positioning or adjustment, which cannot achieve continuous and efficient cutting operations.

[0041] Example 2: Figure 2-6 As shown, as an improvement to the previous embodiment.

[0042] Specifically, the output end of the reduction motor 10 is fixedly connected to the drive shaft 9, and a toothed disc is fixedly connected to the outside of the drive shaft 9 and meshes with the chain 19. The advantage is that when the cutter 5 is provided, the reduction motor 10 is started to rotate the drive shaft 9 during use, which drives the chain 19 and the grab assembly 17 outside the chain 19 to move.

[0043] Specifically, the left end of the second spring 1703 is fixedly connected to the base 1701, and the right end of the second spring 1703 is fixedly connected to the cylinder 1702. The middle part of the guide plate 18 is a horizontal structure, and the front and rear ends are both retracted structures. The advantage is that there are two grabbing components 17. When in use, the grabbing components 17 move with the chain 19, and the moving path at the upper end of the guide rail 11 is from front to back. When the first grabbing component 17 flips to the upper end of the guide rail 11, the guide rail 11 guides the grabbing component 17, so that the grabbing component 17 is in a horizontal state. During the movement, the pulley 1705 contacts the inclined structure at the front end of the guide plate 18. The pulley 1705 moves to the left after being squeezed, driving the cylinder 1702 and the clamping seat 1704 to move to the left. When the pulley 1705 contacts the middle part of the guide plate 18, the clamping seat 1704 and the base 1701 are separated to the maximum gap to accommodate the steel wire. During continuous movement, the pulley 1705 contacts the inclined structure at the rear end of the guide plate 18, and the gap between the clamping seat 1704 and the base 1701 is reduced until the steel wire is clamped, and the grabbing component 17 pulls the steel wire backward.

The advantage is that when the cutting assembly 16 is set, the grabbing assembly 17 pulls the steel wire to move, and contacts the gear rod 1604 of the cutting assembly 16, driving the cutting assembly 16 to move backward, and the spring 14 is stretched. During this process, the roller of the guide rod 1603 rolls on the bottom plate 1501 until it contacts the rotating ramp 1503. The guide rod 1603 moves upward along the rotating ramp 1503, pushing the rotating seat 1601 to rotate around the sliding column 13. The cutter 1602 approaches the steel wire grabbed by the grabbing assembly 17 until the previous section of the steel wire is cut, and the guide rod 1603 is pulled upward. After the rod 1603 reaches the top of the rotating ramp 1503, it falls and lands on the inclined plate 1502. The height of the inclined plate 1502 is relatively low, and the gear lever 1604 is in an upward tilted state. The gear lever 1604 is separated from the base 1701, and the spring 14 contracts to drive the cutting assembly 16 back to its original position along the inclined plate 1502.

[0046] Working principle: When in use, the wire roll 2 is plugged into the mounting rod 104, and the fluororubber pad provided on the surface of the turntable 102 provides greater friction. When the turntable 102 rotates to cut the wire, the wire roll 2 rotates and unwinds accordingly, and the movable seat 305 is inserted into the groove 303, and the mounting plate 309 is inserted into the slide groove 306. The splint 304 is installed on the upper end of the mounting seat 302 to limit the movable seat 305. The steel wire of the wire roll 2 is inserted between the straightening wheels 307, and the screw 308 is rotated. The screw 308 is threadedly connected to the mounting seat 302. When the screw 308 rotates, it moves along the mounting seat 302, thereby adjusting the position of the movable seat 305, so that the multiple straightening wheels 307 reach an appropriate spacing, which is convenient for straightening different sizes. The steel wire of the grid is used to cover the top cover 310 on the upper end of the mounting seat 302. The steel wire passes through the long groove 311 to fix the fixing plate 312 to the top cover 310. The long groove 311 and the guide groove 313 cooperate to limit the steel wire. The reduction motor 10 is started to drive the drive shaft 9 to rotate, driving the chain 19 and the grabbing assembly 17 outside the chain 19 to move. The grabbing assembly 17 moves with the chain 19. The moving path at the upper end of the guide rail 11 is from front to back. When the first grabbing assembly 17 flips to the upper end of the guide rail 11, the guide rail 11 guides the grabbing assembly 17 so that the grabbing assembly 17 is in a horizontal state. During the movement, the pulley 1705 contacts the inclined structure at the front end of the guide plate 18. The pulley 1705 is squeezed and moves to the left, bringing The moving cylinder 1702 and the clamping seat 1704 move to the left. When the pulley 1705 contacts the middle of the guide plate 18, the clamping seat 1704 and the base 1701 are separated to the maximum gap to accommodate the steel wire. During the continuous movement, the pulley 1705 contacts the inclined structure at the rear end of the guide plate 18. The gap between the clamping seat 1704 and the base 1701 is reduced until the steel wire is clamped. The grabbing assembly 17 pulls the steel wire backward. When the grabbing assembly 17 pulls the steel wire to move, it contacts the gear lever 1604 of the cutting assembly 16, driving the cutting assembly 16 to move backward. The spring 14 is stretched. During this process, the roller of the guide rod 1603 rolls on the bottom plate 1501 until it contacts the rotating ramp 1503. The guide rod 1603 rotates along the rotating ramp. 1503 moves upward, pushing the swivel seat 1601 to rotate around the sliding column 13, and the cutting machine 1602 approaches the steel wire grabbed by the grabbing assembly 17 until the previous section of the steel wire is cut off. The guide rod 1603 reaches the top of the rotating ramp 1503 and falls onto the inclined plate 1502. The height of the inclined plate 1502 is relatively low, and the gear lever 1604 is in an inclined upward state. The gear lever 1604 is separated from the base 1701, and the spring 14 contracts to drive the cutting assembly 16 back to its original position along the inclined plate 1502. The first grabbing assembly 17 grabs the steel wire and moves until the second grabbing assembly 17 grabs the steel wire and drives the cutting assembly 16 to cut this section of the steel wire. This process is repeated to automatically track and cut the steel wire. The structure is ingenious and saves manpower.
