Description

Technical Field

[0001] The invention relates to the technical field of nut processing, in particular to a continuous processing and forming device for hard alloy nuts. Background Art

[0002] Carbide nuts are nuts made of carbide materials, usually used in situations where high strength and wear resistance are required. Carbide is a composite material composed of metal and carbide, usually with high hardness, wear resistance and corrosion resistance, suitable for use in extreme environments;

[0003] In the production process of cemented carbide nuts, the selected metal powder and carbide powder need to be mixed in proportion and placed in a mold of a specific shape. A preliminary nut shape is formed by high-pressure pressing, and the pressed green body is placed in a high-temperature sintering furnace for sintering. The high temperature makes the powder particles fuse together to further improve its strength. After sintering, cemented carbide nuts usually need to be threaded. Usually, special cutting tools (such as cemented carbide tools) are used for thread spinning. When the alloy tool is used to spin the thread of the cemented carbide nut, metal scraps will be wrapped around the alloy tool. The entanglement of the metal scraps will hinder the contact between the coolant and the nut and the alloy tool. The heat generated during the thread processing of the alloy tool cannot be dissipated in time, which will reduce the tool life. The entangled scraps will scratch the nut when they come into contact with the nut surface during rotation. The scratches will affect the surface finish of the nut and reduce the product quality. Secondly, the inner wall thread processing of the nut usually uses a rotary tapping machine. The rotary tapping machine can only perform thread processing on a single thread at a time, and the production and processing efficiency has certain limitations. In view of the above problems, the inventor proposes a continuous processing and forming device for cemented carbide nuts to solve the above problems. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention sets a workstation alternating component and a waste chip cleaning component. The workstation alternating component drives two corresponding alloy thread cutters to rotate counterclockwise during the alternation process, and the waste chips are thrown out by the centrifugal force generated by the reverse rotation. The step-by-step intermittent feeding component is set, so that the step-by-step intermittent feeding component drives the hard alloy thread intermittent feeding and simultaneously drives the workstation alternating component to alternate once. Through the above operation, the waste chips wrapped around the alloy thread cutters are automatically cleaned during the alternation process, and the loading and unloading are performed simultaneously;

[0017] 2. The present invention sets a station alternating component and a waste chip cleaning component, so that when the station alternating component drives the transmission shaft to pass through the waste chip cleaning component, the transmission shaft always keeps rotating counterclockwise. The counterclockwise rotation of the transmission shaft is opposite to the clockwise rotation direction of the No. 1 motor, so that the waste chips wound clockwise by the alloy thread cutter in the process of threading are reversely rotated in the alternating process to change the original winding structure of the waste chips and reduce the adhesion between the waste chips and the tool. The centrifugal force generated by the reverse rotation loosens and falls off the wound waste chips, so as to avoid the waste chips wound on the alloy thread cutter from scratching the nut during the rotation process, thereby improving the product quality.

[0018] 3. The present invention sets a station alternating component and a step-by-step intermittent feeding component, so that the step-by-step intermittent feeding component drives the station alternating component to replace two alloy thread cutters synchronously while loading and unloading. The two groups of stations operate simultaneously to improve the production efficiency of opening thread grooves in alloy nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Working principle: First, control the No. 2 motor 710 to rotate clockwise, and the driving end of the No. 2 motor 710 drives the driving shaft 702 to rotate one circle clockwise through the pulley transmission group. During the rotation of the driving shaft 702, the protrusion of the No. 1 cam 703 first contacts the No. 1 roller 609, pushing the No. 1 folding rod 608 to flip upward with the connection of the No. 1 fixed block 607 as the axis. The No. 1 folding rod 608 pushes the No. 2 folding rod 612 to flip upward synchronously with the connection of the No. 2 fixed block 611 as the axis through the No. 1 connecting rod 610. The No. 2 folding rod 612 slides at the bottom of the No. 2 lifting frame 604 through the No. 2 roller 613 to push the No. 2 lifting frame 604 to rise under the guidance of the No. 4 guide rail 603. After the No. 2 lifting frame 604 has finished rising, the No. 2 cam 70 The protrusion of No. 4 contacts with the third roller 617 and pushes the bottom of the slide bar 615 to flip to the right side with the rotating frame 614 as the axis through the third roller 617. The flipping of the slide bar 615 stretches the third reset spring 618, and the upper part of the slide bar 615 flips to the left side with the rotating frame 614 as the axis. The upper part of the slide bar 615 drives the second moving plate 602 to move to the left side under the guidance of the third guide rail 601 through the second connecting rod 616. The second moving plate 602 moves to the left side and drives the loading frame 605 to move to the left side synchronously. After the loading frame 605 moves to the left side, the driving shaft 702 continues to rotate to make the protrusion of the first cam 703 separate from the first roller 609 first, and according to the above reverse operation, the second lifting frame 604 is driven to descend. After the second lifting frame 604 is lowered, the second lifting frame 604 is driven to descend. The protrusion of the cam 704 is separated from the No. 3 roller 617, and the slide bar 615 is reset under the action of the No. 3 reset spring 618, and the No. 2 movable plate 602 is driven to move to the right and reset according to the above reverse operation. According to the above operations, the carbide nuts on the workbench 8 are transported to the bottom of the alloy tool in sequence through the step-by-step movement of the loading frame 605. When the thread is opened in the carbide nut, the No. 2 motor 710 stops running, and the carbide nut is clamped and fixed by an external fixing device, and then the No. 1 motor 405 is controlled to rotate clockwise, and the driving end of the No. 1 motor 405 drives the rotating column 406 to rotate, and the rotating column 406 drives the alloy thread cutter 407 to rotate synchronously, and the electric cylinder 408 is started synchronously, and the driving end of the electric cylinder 408 extends and pushes The No. 1 lifting frame 404 descends under the guidance of the No. 2 guide rail 403 so that the rotating alloy thread cutter 407 rotates on the carbide nut to open the thread. After the thread opening is completed, the No. 1 lifting frame 404 rises and resets. After the No. 1 lifting frame 404 is reset, the No. 1 motor 405 is turned off, and the No. 2 motor 710 is continuously turned on. The No. 2 motor 710 drives the driving shaft 702 to rotate clockwise once to realize one loading. During the loading process, the driving shaft 702 rotates one circle and drives the driven shaft 706 to rotate half a circle synchronously through the pulley transmission group. The driven shaft 706 drives the connecting shaft 707 to rotate half a circle through the No. 1 bevel gear 708 and the No. 2 bevel gear 709. The connecting shaft 707 drives the rotating shaft 303 to rotate half a circle through the synchronous wheel transmission group.The rotation of the rotating shaft 303 drives the rotating rod 304 to rotate, and the rotating rod 304 drives the left sliding frame 308 to move to the right through the sliding frame 302, and the right sliding frame 308 is synchronously switched to the left through the transmission belt 306. During the movement of the sliding frame 308, the No. 1 moving plate 402 is driven to move toward the side of the corresponding side plate 501 under the guidance of the No. 1 guide rail 401 under the action of the guide wheel 410 and the guide groove 310. The two No. 1 moving plates 402 move synchronously toward the side of the corresponding side plate 501 during the alternation process to avoid collision so that the two alloy thread cutters 407 always remain on the same horizontal line after the alternation is completed. The movement of the No. 1 moving plate 402 drives the corresponding No. 1 lifting plate 501 to move. The second extension plate 411 on the descending frame 404 moves synchronously. During the alternating process, when the sliding frame 308 moves from the left to the right, the guide plate 511 will be located in the middle of the first arched guide frame 502 and the second arched guide frame 503. Under the guidance of the guide plate 511, the transmission gear 510 is meshed with the first rack 504. The transmission gear 510 rotates counterclockwise on the first rack 504 as it moves. The transmission gear 510 drives the transmission shaft 509 to rotate synchronously counterclockwise. The transmission shaft 509 drives the rotating column 406 to rotate synchronously counterclockwise through the synchronous wheel transmission group. The rotating column 406 rotates counterclockwise to drive the alloy thread cutter 407 to rotate counterclockwise, and the first motor 405 rotates counterclockwise. The rotation direction is opposite, and the waste chips originally wrapped around the alloy thread cutter 407 are thrown outward due to the centrifugal force through the reverse rotation, and fall onto the baffle plate, and are discharged under the guidance of the baffle plate. When the guide plate 511 moves to the folding plate 507, the guide plate 511 moves and pushes the folding plate 507 to fold outward. After the guide plate 511 is separated from the folding plate 507, it is reset under the action of the No. 1 reset spring 508. When the sliding frame 308 moves from the right to the left, when the guide plate 511 moves to the folding plate 507, the guide plate 511 will move upward along the folding plate 507 and the inclined plate 506 to the No. 1 arched guide frame 502 and the No. 2 arched guide frame 503 The transmission gear 510 and the guide plate 511 rise under the guidance of the transmission shaft 509 and push the reset plate 516 to rise synchronously to squeeze the No. 2 reset spring 517. At this time, the transmission gear 510 is meshed with the No. 2 rack 505. The transmission gear 510 drives the transmission shaft 509 to rotate counterclockwise synchronously under the action of the No. 2 rack 505, and the transmission shaft 509 always keeps rotating counterclockwise during the alternating process. When the guide plate 511 is separated from the No. 1 arched guide frame 502 and the No. 2 arched guide frame 503, the reset plate 516 is pushed downward under the guidance of the No. 2 reset spring 517, and the guide plate 511 and the transmission gear 510 are pushed to reset through the reset plate 516.
