Until the lowering block 505 moves to the lower part of the rod, the first electric telescopic rod 309 drives the clamping block 305 to separate from the surface of the rod, and the rod can fall onto the surface of the lowering block 505. Then, the second rotating shaft 503 is driven clockwise by the second electric telescopic rod 510 to rotate clockwise, and the rod can be poured into the cleaning box 501 to complete the unloading. When the motor 312 drives the slide 303 to move closer to the mold frame 301, the second push plate 515 is driven to move synchronously through the third connecting rod 516 to push the rods in the cleaning box 501 to the surface of the storage plate 502 for storage, which is convenient for use.

[0048] A rod drawing method, applicable to the above-mentioned rod drawing device, comprises the following steps:

[0049] S1: feeding; the rod to be drawn is placed on the surface of the placement rack 401. When the motor 312 drives the slide 303 to move closer to the mold frame 301, the connecting plate 408 is driven to move synchronously, so that the first tooth plate 409 is meshed with the one-way gear 407, and the loading barrel 402 is driven to rotate clockwise for one circle, and the rod in the loading trough 403 is moved to the surface of the frame 2. With the movement of the connecting plate 408, when the third tooth plate 413 is meshed with the third gear 412, the first push plate 410 is driven to move closer to the frame 2, and one end of the rod on the surface of the frame 2 is pushed into the forming hole 302, and the loading is completed;

[0050] S2: Drawing; the motor 312 drives the slide 303 to move to the side wall of the die frame 301, drives the clamping blocks 305 on both sides to move closer, clamps and fixes the rod head, and then drives the slide 303 to move away from the die frame 301 to draw the rod. At the same time, the screw rod 311 drives the driving disk 319 to rotate synchronously, thereby driving the driving frame 320 to swing left and right, driving the piston 315 to move synchronously, so that the first one-way valve 317 and the second one-way valve 318 are alternately turned on, and the lubricating oil in the oil groove 313 is injected into the annular cavity 322, and sprayed onto the surface of the rod from the oil injection hole 323 to complete the coating of the lubricating oil;

[0051] S3: unloading; the fourth tooth plate 509 is driven to move by the second electric telescopic rod 510, thereby driving the fourth gear 508 to drive the second rotating shaft 503 to rotate counterclockwise, and the unloading block 505 is moved to the lower part of the rod. The first electric telescopic rod 309 drives the clamping block 305 to separate from the surface of the rod, and the rod can fall onto the surface of the unloading block 505. Then, the second rotating shaft 503 is driven clockwise by the second electric telescopic rod 510 to pour the rod into the cleaning box 501, and the unloading is completed. When the motor 312 drives the slide 303 to move closer to the mold frame 301, the third connecting rod 516 drives the second push plate 515 to move synchronously, and the rods in the cleaning box 501 are pushed to the surface of the storage plate 502 for storage.

[0052] Specifically, the working principle of the rod drawing device is as follows: when in use, the rod to be drawn is placed on the surface of the placement rack 401, and under the action of gravity, the rod moves toward the upper barrel 402 and enters the loading trough 403 in sequence. When the motor 312 drives the slide 303 to move toward the mold frame 301, it drives the connecting plate 408 to move synchronously, so that the first tooth plate 409 is engaged with the one-way gear 407, and drives the one-way gear 407 and the first rotating shaft 40 5 rotates counterclockwise for one circle, thereby driving the loading barrel 402 to rotate clockwise for one circle. During the rotation of the loading barrel 402, the rods in the loading trough 403 can be moved to the surface of the frame 2. With the movement of the connecting plate 408, when the third tooth plate 413 is meshed with the third gear 412, the second tooth plate 411 is driven to drive the first push plate 410 to move closer to the frame 2, and one end of the rod on the surface of the frame 2 is pushed into the forming hole 302, completing the loading and improving the drawing efficiency.

[0053] Then, the motor 312 drives the screw rod 311 to rotate, thereby driving the slide 303 to move to the side wall of the mold frame 301, so that the tying head is inserted between the two clamping blocks 305, and the V-shaped driving block 308 can be driven to move toward the wedge block 307 through the first electric telescopic rod 309, thereby driving the clamping blocks 305 on both sides to move closer and clamp the rod tying head. Then, the motor 312 drives the screw rod 311 to reverse, drive the slide 303 to move away from the mold frame 301, and pull the rod. At the same time, the screw rod 311 drives the driving disk 319 to rotate synchronously, thereby driving the driving frame 320 to swing left and right, driving the piston 315 to move synchronously, so that the first one-way valve 317 and the second one-way valve 318 are alternately turned on, and the lubricating oil in the oil groove 313 is injected into the annular cavity 322, and sprayed onto the surface of the rod from the oil filling hole 323, completing the coating of the lubricating oil for easy use.

[0054] After the drawing is completed, the fourth tooth plate 509 is driven to move by the second electric telescopic rod 510, thereby driving the fourth gear 508 to drive the second rotating shaft 503 to rotate counterclockwise. When the lowering block 505 contacts the surface of the bar, the wedge surface of the lowering block 505 is squeezed, the second spring 507 contracts, and the lowering block 505 is retracted into the inner cavity of the swing arm 504. Until the lowering block 505 moves to the lower part of the bar, the first electric telescopic rod 309 drives the clamping block 305 to separate from the surface of the bar, and the bar can fall onto the surface of the lowering block 505, and then the second rotating shaft 503 is driven clockwise by the second electric telescopic rod 510 to rotate clockwise, so that the bar can be poured into the cleaning box 501 to complete the unloading. When the motor 312 drives the slide 303 to move closer to the mold frame 301, the third connecting rod 516 drives the second push plate 515 to move synchronously, and the bars in the cleaning box 501 are pushed to the surface of the storage plate 502 for storage, which is convenient for use.
