DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] like Figures 1 to 5 As shown, the present invention provides an embodiment of a wire rod processing and straightening device, including a wire rod shelling machine body 1, the wire rod shelling machine body 1 is used to straighten the wire rod 2, and also includes a dephosphorization mechanism 3, a wire clamping mechanism 4 and a locking mechanism 5, the dephosphorization mechanism 3 includes a rotating base 6, an elastic limiter 7, a connecting plate 8 and two extrusion dephosphorization rollers 9, the two extrusion dephosphorization rollers 9 are rotatably installed at both ends of the connecting plate 8, the center of the connecting plate 8 is fixed on the rotating base 6, the rotating base 6 is rotatably installed on the elastic limiter 7, the wire rod 2 can pass between the two extrusion dephosphorization rollers 9 after being straightened, and the elastic limiter 7 presses the two extrusion dephosphorization rollers 9 onto the wire rod 2 by pushing the connecting plate 8 to rotate.

[0024] There are two elastic limiters 7, and the two elastic limiters 7 are centrally symmetrically arranged with the rotating base 6 as the center. Each elastic limiter 7 includes a fixed base 14, a fixed plate 15, a movable plate 16, a return spring 17 and a positioning plate 18. The rotating base 6 is rotatably mounted on the upper surface of the fixed base 14, the fixed plate 15 is mounted on one side of the fixed base 14, and the positioning plate 18 is mounted on the other side of the fixed base 14. The movable plate 16 is fixed to the bottom of the connecting plate 8 and is located between the fixed plate 15 and the positioning plate 18. The two ends of the return spring 17 are respectively connected to the fixed plate 15 and the movable plate 16. The return spring 17 is used to push the movable plate 16 toward the positioning plate 18.

[0025] The working principle of the elastic limiter 7 is as follows: when the straightened wire rod 2 passes through the two extrusion dephosphorization rollers 9, the reset spring 17 is compressed, and the extrusion dephosphorization roller 9 is pressed against the wire rod 2 by the thrust provided by the reset spring 17. After the straightened wire rod 2 is squeezed by the extrusion dephosphorization roller 9, the oxidized rust on the surface is crushed and peeled off from the wire rod 2, thereby achieving the purpose of dephosphorizing the wire rod 2. When the wire rod 2 is not broken, it can be understood that the two extrusion dephosphorization rollers 9 are limited by the wire rod 2, so that the reset spring 17 is always kept in a compressed state. If the wire rod 2 breaks during the dephosphorization process, the two extrusion dephosphorization rollers 9 are lost. Remove the limit, the reset spring 17 can push the connecting plate 8 and the movable plate 16 to rotate around the rotating base 6. During the rotation of the connecting plate 8, the extrusion and dephosphorization roller 9 will drive the extrusion and dephosphorization roller 9 to move toward the wire-carding mechanism 4. During the movement of the extrusion and dephosphorization roller 9, the broken wire rod 2 will be pushed to move to the wire-carding mechanism 4. Finally, the broken part of the wire rod 2 is fixed by the wire-carding mechanism 4 to prevent the wire rod 2 from breaking and flying off, thereby reducing the safety hazard caused by the breakage of the wire rod 2. On the other hand, a limit switch can also be installed under the connecting plate 8. When the limit switch is triggered, the power supply of the wire rod 2 shelling machine is disconnected to stop conveying the wire rod 2.

[0026] The dephosphorization mechanism 3 also includes an active motor 13, which is fixed under the rotating base 6 and is used to drive the extrusion dephosphorization roller 9 to rotate. The extrusion dephosphorization roller 9 is a steel roller, and a plurality of rubber strips 28 are fixed on the surface of the extrusion dephosphorization roller 9. The rubber strips 28 can prevent the wire rod 2 from slipping on the one hand, and can also increase the friction between the extrusion dephosphorization roller 9 and the wire rod 2 on the other hand, so that the oxidized rust on the surface of the wire rod 2 can be more easily peeled off.

[0027] The wire clamping mechanism 4 includes a claw seat 10, a fixed claw 11 and a movable claw 12. The fixed claw 11 is connected to the elastic limiter 7 through the claw seat 10. The height of the fixed claw 11 is greater than the height of the wire rod 2, and the height of the movable claw 12 is less than the height of the wire rod 2. When the wire rod 2 breaks, the extrusion dephosphorization roller 9 can press the wire rod 2 between the fixed claw 11 and the movable claw 12 to fix the wire rod 2.

[0028] The thread clamping mechanism 4 also includes a push plate 19, a push rod 20, a guide rod 21, a slider 22 and a top block 23. The fixed claw 11 is fixed to the top of the claw seat 10, and the movable claw 12 is vertically slidably installed on the claw seat 10 and is located below the fixed claw 11. The tail end of the movable claw 12 is fixedly connected to the slider 22. The lower surface of the slider 22 is an inclined surface and slides with the upper surface of the top block 23.

[0029] The push rod 20 and the guide rod 21 are vertically slidably installed on the positioning plate 18, and the two ends of the push plate 19 are respectively connected to the push rod 20 and the guide rod 21. When the movable plate 16 moves toward the positioning plate 18, the movable plate 16 can push the push plate 19, the push rod 20 and the guide rod 21 to move. A slide rail 24 is also fixed to the bottom of the claw seat 10, and the top block 23 is slidably installed in the slide rail 24. The push rod 20 is fixedly connected to the bottom of the top block 23. The push rod 20 is used to push the top block 23 to move horizontally, and the top block 23 is used to push the slider 22 to move vertically.

[0030] The working principle of the wire clamping mechanism 4 is: when the wire rod 2 breaks, the reset spring 17 pushes the movable plate 16 toward the positioning plate 18, and the extrusion dephosphorization roller 9 pushes the broken wire rod 2 toward the fixed claw 11 and the movable claw 12, and because the diameter of the extrusion dephosphorization roller 9 is larger, the wire rod 2 will be pushed into between the fixed claw 11 and the movable claw 12 first, and then the movable plate 16 contacts with the push plate 19 and pushes the push plate 19 toward the positioning plate 18, so that the push rod 20 pushes the top block 23 to slide horizontally along the slide rail 24, and when the top block 23 slides horizontally, it pushes the slider 22 to move upward, and the slider 22 moves upward to drive the movable claw 12 to move toward the fixed claw 11, and then the broken wire rod 2 is clamped by the movable claw 12 and the fixed claw 11.

[0031] The locking mechanism 5 is used to limit the movable claw 12. The locking mechanism 5 includes a socket 25 and a latch 26. The guide rod 21 is slidably connected to the socket 25. The latch 26 is plugged into the top of the socket 25. The bottom end of the latch 26 abuts against the guide rod 21. A limiting opening 27 is provided on the guide rod 21. When the limiting opening 27 moves to the bottom of the latch 26, the latch 26 can be inserted into the limiting opening 27.

[0032] When the movable plate 16 drives the push plate 19 to move, it will also drive the guide rod 21 to slide along the socket 25. When the movable claw 12 clamps the broken wire rod 2, the limit opening 27 on the guide rod 21 just moves to the bottom of the latch 26, so that the latch 26 can be inserted into the limit opening 27 to lock the guide rod 21. After the locking is completed, even if the return spring 17 vibrates and causes the movable plate 16 to disengage from the push plate 19, the push plate 19, the push rod 20 and the top block 23 can still maintain the locked state to prevent the wire rod 2 from loosening from the movable claw 12 and the fixed claw 11. When it is necessary to unlock, only the latch 26 needs to be pulled out to allow the movable claw 12 to move down smoothly to loosen the wire rod 2.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above are only preferred implementation methods of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
