[0060] The usage method and advantages of the present invention: The thread cutting device for fastener processing works as follows:

[0061] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 shown in

[0062] S1: When the cutting starts, control the driving motor 2 to drive the reciprocating lead screw 3 to rotate, so that the cutting table 402 translates to one side of the machine table 1 for loading operation. When the mounting shaft 401 contacts the end face of the transmission cylinder 409, the transmission cylinder 409 drives the rotating cylinder 408 to translate from the front side of the sleeve 407 to the rear side. At this time, the transmission cylinder 409 gradually compresses the first spring 414, and at the same time, the positions of the transmission cylinder 409 and the rotating cylinder 408 do not change. After the rotating cylinder 408 contacts the end face of the sleeve 407, the rotating cylinder 408 stops horizontal movement. At this time, the mounting shaft 401 continues to push the transmission cylinder 409 into the rotating cylinder 408, so that the transmission cylinder 409 is gradually retracted into the rotating cylinder 408. At the same time, when the convex block 413 follows the translation, it slides in the spiral groove 411, causing the rotating groove to rotate. The clamping rod 410 contacts the retaining piece 405 and wraps the retaining piece 405. When the rotating groove rotates, it drives the cutting table 402 to rotate synchronously, so that the cutting table 402 rotates 180 degrees during the horizontal movement, causing the two pneumatic clamps 404 above and below the cutting table 402 to exchange positions;

[0063] S2: When the sleeve 407 is retracted into the rotating cylinder 408 and starts to rotate, the lever 418 abuts against the dial head 417, causing the lever 418 to drive the dial head 417 to rotate synchronously. At the same time, the belt 416 is tightened, causing the slide block 421 on the side table 406 to drive the first rack 422 to translate. The first rack 422 drives the second rack 603 to move in the opposite direction through the gear, causing the feeding table 607 on the mounting frame 601 to move from above the cutting table 402 to above the conveyor belt 605. After moving above the first fastener blank at the front, the lever 418 contacts the release block 420, and the lever 418 approaches the clamping rod 410, gradually disconnecting from the dial head 417, causing the third spring 423 to be quickly released. The second rack 603 returns to its original position, causing the feeding table 607 to drive the blank to translate above the cutting table 402. After the two clamping arms 608 contact the trigger plate 615, the clamping of the blank is released, allowing the blank to automatically fall into the pneumatic fixture 404 that has been repositioned through the feeding port 602. During the clamping process of the two clamping arms 608, when passing through the third rack 614, the second gear 610 rotates. Through several toothless openings 611 opened inside it, the clamping plate 612 is clamped during rotation, driving the double-sided cam 609 to rotate. Before approaching the first blank, the double-sided cam 609 rotates and synchronously opens the two clamping arms 608. After aligning with the upper part of the blank, the second gear 610 disengages from the third rack 614, and the double-sided cam 609 returns to its initial state under the clamping action of the two clamping arms 608, with its convex surface not contacting the clamping arms 608. The two clamping arms 608 move relatively closer and clamp the blank. When the clamping arms 608 move towards the pneumatic fixture 404, through the clamping rod 410 and the toothless openings 611, when the second gear 610 meshes with the third rack 614 again, the clamping rod 410 inside the second gear 610 is pressed back into the double-sided cam 609, thus not driving the double-sided cam 609 to rotate again. After the blank is clamped and taken away, the servo motor 606 rotates the conveyor belt 605 by a distance equal to the diameter of one blank;

[0064] S3: After the blank enters the pneumatic fixture 404, the pneumatic fixture 404 automatically tightens to clamp the blank. When the frame body 501 approaches one side of the machine table 1, the inclined opening of the dislocating plate 505 contacts the disengaging rod 506, causing the dislocating plate 505 to drive the side plate 503 and the retaining shaft 504 to automatically rise. Subsequently, the pneumatic fixture 404 disconnects from the clamping of the retaining shaft 504. When the pneumatic fixture 404 returns to its original position, it pushes the group of retaining shafts 504 that have not risen forward, and the raised retaining shaft 504 automatically falls and clamps the other side of the pneumatic fixture 404. Subsequently, the cutting motor 502 is started, and during the movement of the pneumatic fixture 404 and the cutting table 402, it moves synchronously with them to perform thread cutting on the blank inside the pneumatic fixture 404;

[0065] S4: When the pneumatic fixture 404 exchanges positions again, turn the end where cutting is completed downward, and load the upward-turned end. When moving again for cutting, as the gear at the bottom of the frame body 501 moves synchronously, it meshes with the rack four 701 and rotates. And the control rod 707 passes through the ramp 706, its position gradually rises and tends to be horizontal, so that the height of the brush barrel 705 gradually rises during rotation and extends into the interior of the cut fastener located below, continuously rotates to clean the cutting debris, and moves downward on the other side of the ramp 706 and automatically withdraws from the interior of the fastener to complete the chip cleaning operation. When the pneumatic fixture 404 moves above the discharge port 9, it automatically opens for discharging, and the cut fasteners are stacked at the discharge port 9.
