[0002] Wire straightening is a processing technology used to trim and straighten the steel wire to make it straighter and more regular.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a wire straightening machine, which has the following beneficial effects:

[0020] 1. The present invention drives the reciprocating screw to rotate, and the transmission reciprocating block reciprocates to drive the sleeve and the straightening and shaping cylinder to move. When the straightening and shaping cylinder moves in the same direction and at the same speed as the steel wire material, the first telescopic electric rod is controlled to extend, and the annular push plate pushes the first driving rod to make the straightening roller approach and press against the surface of the steel wire material. At the same time, the active pulley drives the straightening roller to rotate along the surface of the steel wire material through the transmission belt, so that the straightening roller rolls along the surface of the steel wire material, and the surface of the steel wire material is straightened and shaped twice. By utilizing the above structure, the steel wire can be evenly shaped at all angles, and the straightening roller and the steel wire material can be kept relatively still, thereby improving the radial rounding effect of the steel wire and reducing the wear between the straightening roller and the steel wire material.

[0021] 2. The present invention provides an anti-deformation component. When the straightening and shaping cylinder moves in the same direction and speed as the steel wire material, the controller controls the extension of the second telescopic electric rod to allow the fixed chuck to clamp the steel wire material, thereby improving the restraint effect on the steel wire material and the stability during the shaping process, thereby preventing the straightening roller from generating torque on the steel wire material to cause twisting and deformation of the steel wire material.

[0022] 3. Through the setting of the centering component, the present invention enables the second telescopic electric rod and the first telescopic electric rod to contract when the straightening and shaping cylinder and the steel wire material move in opposite directions, and the fixation of the steel wire material is released. The annular push plate pulls the first driving rod to make the straightening roller move away from the steel wire material. At the same time, the annular push plate pushes the second driving rod, and the centering frame centers and supports the steel wire material, so that the steel wire material remains straight during this process, avoiding the steel wire material from bending due to gravity, thereby improving the overall straightening and shaping effect of the straightening machine.

[0023] 4. The present invention arranges the wire cutting component so that the telescopic cylinder drives the wire cutting cutter head to cut the steel wire material when the wire cutting cutter head and the steel wire material move in the same direction and at the same speed. There is no need to stop the conveying of the steel wire material during the cutting time, thus saving the cutting time and improving the processing efficiency of the steel wire material. When the wire cutting platform moves in the opposite direction, the cut part of the steel wire material will be pushed out by the uncut part and fall into the blanking box, which is convenient for the collection of the cut material and improves the overall practicality of the straightening machine.

[0024] 5. The present invention can realize automatic backward conveyance of steel wire material through the arrangement of straightening and traction components, radial straightening and shaping components, centering components, anti-deformation components, and broken wire components, which is convenient for installation when replacing steel wire material and simple and convenient to operate.

[0045] Among them, the straightening traction component 2 is an existing component; the reciprocating block 403 is driven by the reciprocating screw rod 401 to drive the straightening and shaping cylinder 410 to move back and forth, so that the straightening roller 412 and the steel wire material 10 maintain the same speed and the same direction of displacement, so that the two are relatively stationary, reducing the wear of the straightening roller 412 and the steel wire material 10; when the driven pulley 406 rotates, the limit connecting rod 408 can drive the straightening and shaping cylinder 410 to rotate, so that the straightening roller 412 can rotate and shape and straighten along the surface of the steel wire material 10; through the extension and retraction of the first telescopic electric rod 414, when the straightening roller 412 and the steel wire material 10 move in the same direction and at the same speed, the straightening roller 412 can be pressed against the surface of the steel wire material 10, and when the straightening roller 412 and the steel wire material 10 move in the opposite direction, the straightening roller 412 is separated from the steel wire material 10 to avoid the influence of the reverse force of the straightening roller 412 on the steel wire material 10.

[0047] Specifically, the sensing information is fed back to the controller 5 through the laser displacement sensor 416, and then the controller 5 automatically controls the straightening and traction assembly 2, the driving motor 402, and the first telescopic electric rod 414 to perform corresponding operations.

[0048] Preferably, an electric heating mechanism is provided inside the straightening roller 412 , and the steel wire material 10 is heated by the electric heating mechanism to improve the plasticity of the steel wire material 10 , thereby facilitating the straightening roller 412 to shape it.

[0049] For further example 2, please refer to Figure 6 to Figure 7 As shown:

[0050] It also includes a centering component 6 for centering and supporting the steel wire material 10 after straightening and shaping. The centering component 6 includes four centering frames 601 that are slidably connected along the diameter direction of the straightening and shaping cylinder 410. The centering frame 601 is rotatably connected to the side of the steel wire material 10 with a centering wheel 602. The annular push plate 413 is also rotatably connected to a second driving rod 603. The second driving rod 603 is rotatably connected to the centering frame 601 at one end away from the annular push plate 413.

[0051] Preferably, each centering frame 601 corresponds to a group of centering wheels 602 arranged in a horizontal straight line, and the middle part of the centering wheel 602 is a concave structure adapted to the steel wire material 10, the first driving rod 415 and the second driving rod 603 are respectively arranged on both sides of the annular push plate 413, and the four roller frames 411 and the four centering frames 601 are staggered.

[0052] Specifically, when the straightening and shaping cylinder 410 moves in the same direction and speed as the steel wire material 10 and the first telescopic electric rod 414 is extended, the straightening roller 412 presses the steel wire material 10 and the centering wheel 602 moves away from the steel wire material 10. When the straightening and shaping cylinder 410 and the steel wire material 10 move in the opposite direction and the first telescopic electric rod 414 is contracted, the straightening roller 412 moves away from the steel wire material 10 and the centering wheel 602 presses the steel wire material 10 to support and center the steel wire material 10 to prevent the steel wire material 10 from bending due to gravity.

[0053] For further example 3, please refer to Figure 8 As shown:

[0054] It also includes an anti-deformation component 7 for clamping both sides of the steel wire material 10 during the straightening and shaping process, the anti-deformation component 7 includes a clamping ring frame 701 rotatably connected to the two end surfaces of the straightening and shaping cylinder 410, the upper and lower sides of the clamping ring frame 701 in the diameter direction are fixedly connected with a second telescopic electric rod 702, the end of the second telescopic electric rod 702 away from the clamping ring frame 701 is fixedly connected with a fixed chuck 703, the clamping surface of the fixed chuck 703 is provided with an anti-slip pad 704, the left and right sides of the clamping ring frame 701 in the diameter direction are fixedly connected with a telescopic rod 705, the end of the telescopic rod 705 away from the clamping ring frame 701 is fixedly connected with an L-shaped frame 706, the L-shaped frame 706 is fixedly connected to the outside of the straightening frame 3, and the second telescopic electric rod 702 is electrically connected to the controller 5;

[0055] Specifically, according to the sensing information of the laser displacement sensor 416, the controller 5 automatically controls the second telescopic electric rod 702 to perform corresponding operations. When the straightening roller 412 presses the steel wire material 10, the second telescopic electric rod 702 synchronously extends to fix the steel wire material 10, thereby improving the restraint effect on the steel wire material 10 and the stability during the shaping process, thereby preventing the torsion force generated by the straightening roller 412 on the steel wire material 10 from causing the steel wire material 10 to twist and deform. When the straightening roller 412 moves away from the steel wire material 10, the fixed chuck 703 moves away from the steel wire material 10 synchronously to release the fixation of the steel wire material 10.

[0056] Among them, the clamping ring frame 701 is always moved in a straight line through the telescopic rod 705, and the clamping ring frame 701 will not rotate synchronously with the straightening and shaping cylinder 410.

[0057] Preferably, the radius of the clamping ring frame 701 is smaller than the distance between the limiting link 408 and the axis of the clamping ring frame 701 , and the distance between the telescopic rod 705 and the axis of the clamping ring frame 701 is smaller than the radius of the through hole 409 , and the telescopic rod 705 passes through the through hole 409 .

[0058] For further example 4, please refer to Fig. 9 As shown:

[0059] It also includes a wire breaking assembly 8 arranged on the right side of the straightening frame 3 and a blanking box 9 fixedly installed on the straightening machine base 1, the wire breaking assembly 8 includes a wire breaking frame 801, the left side of the wire breaking frame 801 is fixedly connected to the reciprocating block 403, the bottom of the wire breaking frame 801 is fixedly installed with a supporting leg 802, the bottom of the supporting leg 802 is rotatably connected with a supporting wheel 803, the wire breaking frame 801 slides horizontally on the top surface of the straightening machine base 1 through the supporting leg 802 and the supporting wheel 803, a wire breaking platform 804 is fixedly installed on the top of the right side of the wire breaking frame 801, a tool holder 805 is fixedly installed in the middle of the wire breaking platform 804, a telescopic cylinder 806 is fixedly installed on the top of the tool holder 805, a wire breaking cutter head 807 is fixedly connected to the output end of the telescopic cylinder 806, a wire breaking groove 808 located below the wire breaking cutter head 807 is provided on the wire breaking platform 804, and the telescopic cylinder 806 is electrically connected to the controller 5;

[0060] Specifically, according to the sensing information of the laser displacement sensor 416, the controller 5 automatically controls the telescopic cylinder 806 to perform corresponding operations. The cutting length is calculated by the controller 5, so that the telescopic cylinder 806 drives the wire breaking cutter head 807 to cut the steel wire material 10 when the wire breaking cutter head 807 and the steel wire material 10 move in the same direction and at the same speed. There is no need to stop the transportation of the steel wire material 10 during the cutting time, which saves the cutting time and improves the processing efficiency of the steel wire material 10.

[0061] Preferably, the width of the outer side of the tool holder 805 is smaller than the spacing between the L-shaped frames 706, and the width inside the tool holder 805 is larger than the diameter of the steel wire material 10 and less than twice the diameter of the steel wire material 10, so that when the wire breaking platform 804 moves in the opposite direction, the broken part of the steel wire material 10 will be pushed out by the unbroken part and fall into the blanking box 9. The blanking box 9 is located directly below the wire breaking platform 804, and the front and rear sides of the straightening frame 3 are both hollow structures.

[0062] Everything in the above example works like this:

[0063] When in use, the steel wire material 10 is first inserted into the straightening and traction assembly 2 for straightening and shaping, and the steel wire material 10 is conveyed backwards, and the steel wire material 10 passes through the through hole 409 and enters the straightening and shaping cylinder 410. Then the controller 5 starts the driving motor 402, drives the reciprocating screw rod 401 to rotate, and drives the sleeve 404 and the straightening and shaping cylinder 410 to move reciprocatingly through the transmission reciprocating block 403. When the straightening and shaping cylinder 410 moves in the same direction and at the same speed as the steel wire material 10, the controller 5 controls the second telescopic electric rod 702 to extend, so that the fixed clamp 703 clamps the steel wire material 10, and then controls the first telescopic electric rod 41 4 is extended, the annular push plate 413 pushes the first driving rod 415, so that the roller frame 411 and the straightening roller 412 are close to and pressed against the surface of the steel wire material 10. At the same time, the reciprocating screw rod 401 drives the active pulley 405, and the active pulley 405 drives the driven pulley 406, the limiting connecting rod 408, the straightening and shaping cylinder 410, and the straightening roller 412 to rotate through the transmission belt 407, so that the straightening roller 412 performs secondary straightening and shaping on the surface of the steel wire material 10, and the steel wire material 10 is continuously transported backward. At the same time, the steel wire material 10 passes through the knife frame 805, and the telescopic cylinder 806 is started, so that the wire breaking knife head 807 cuts the steel wire material 10.

[0064] When the straightening and shaping cylinder 410 moves in the opposite direction to the steel wire material 10, the second telescopic electric rod 702 and the first telescopic electric rod 414 contract to release the fixation of the steel wire material 10, and the annular push plate 413 pulls the first driving rod 415 to make the straightening roller 412 move away from the steel wire material 10. At the same time, the annular push plate 413 pushes the second driving rod 603 to make the centering frame 601 center and support the steel wire material 10, and the wire breaking table 804 and the knife holder 805 move in the opposite direction, and the unbroken part of the steel wire material 10 pushes out the broken part, so that the broken part falls into the blanking box 9 for collection, and the above operation is repeated to straighten and shape the steel wire material 10.
