[0051] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0052] Embodiment 1:

[0053] like Figure 1 As shown, the present invention provides a flattening machine for steel wire processing, comprising:

[0054] A machine platform 1 is provided with an unwinding roller 2, a self-balancing unit 5, a pressure roller assembly and a winding roller 3 in sequence. The pressure roller assembly includes two pressure rollers 4 arranged up and down. The unwinding roller 2, the winding roller 3 and the pressure roller 4 are connected to a power device. A steel wire 6 is led out from the unwinding roller 2, passes through the self-balancing unit 5 and the gap between the two pressure rollers 4 in sequence and is wound around the winding roller 3. The self-balancing unit 5 is used to adjust the position of the steel wire 6 so that it corresponds to the steel wire groove on the pressure roller 4.

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] The present invention provides a flattening machine for steel wire processing, wherein the steel wire 6 to be formed is wound on an unwinding roller 2, the end of the steel wire 6 is led out, passes through a self-balancing unit 5 and steel wire grooves on two pressure rollers 4 in sequence, and is wound on a winding roller 3; during operation, the motors of the unwinding roller 2 and the winding roller 3 are started to drive the unwinding roller 2 and the winding roller 3 to rotate continuously, thereby realizing continuous feeding of the steel wire 6; and the motors of the two pressure rollers 4 are started to drive the pressure rollers 4 to rotate, the steel wire 6 is squeezed in the steel wire groove, and the steel wire 6 is flattened as the pressure rollers 4 rotate. By providing a self-balancing unit 5, the steel wire 6 can correspond to the position of the steel wire groove after passing through the self-balancing unit 5, and when the steel wire 6 deviates from the steel wire groove, the position of the steel wire 6 is automatically adjusted.

[0057] The present invention provides a flattening machine for steel wire processing. A self-balancing unit 5 is arranged in front of a pressing roller 4 to guide the unwound steel wire 6 to correspond to the steel wire groove on the pressing roller 4, so that the steel wire 6 can enter in a direction parallel to the steel wire groove. When the steel wire 6 deviates, the position of the steel wire 6 is automatically adjusted to reduce the squeezing of the steel wire 6 by the end edge of the steel wire groove 8, reduce the friction deformation and damage of the steel wire 6, and improve the quality of the steel wire product.

[0058] Embodiment 2:

[0059] On the basis of the above-mentioned embodiment 1, a plurality of steel wire grooves of different sizes are arranged in parallel on the pressure roller 4 .

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] A plurality of steel wire grooves are arranged on the pressing roller 4 , and the sizes of the steel wire grooves are different, so that the steel wires 6 of different diameters can be accommodated and pressed into the required size, which is suitable for flattening and forming steel wires 6 of various specifications.

[0062] Embodiment 3:

[0063] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1, the front and rear positions of the self-balancing unit 5 are adjustable and locked with the machine 1, and the routing position of the self-balancing unit 5 corresponds to the position of the wire groove currently in use; a guide wheel assembly 8 is arranged between the unwinding roller 2 and the self-balancing unit 5, and the steel wire 6 corresponds to the routing position of the self-balancing unit 5 after wrapping around the guide wheel assembly 8.

[0064] The working principle and beneficial effects of the above technical solution are:

[0065] The self-balancing unit 5 can move forward and backward along the slide rail above the machine 1 and be locked. The preset locking positions of the self-balancing unit 5 correspond to the positions of the wire grooves. When different wire grooves are used, the self-balancing unit 5 can be pre-locked to the balancing position as a reference for subsequent balancing conditions.

[0066] Embodiment 4:

[0067] like Figure 2-4 As shown, based on the above embodiment 1, the self-balancing unit 5 includes:

[0068] A base 11, the base 11 is slidably connected to the machine platform 1, and both sides of the top of the base 11 are set as inclined surfaces;

[0069] A balancing rod 12, the balancing rod 12 is hinged to the middle of the top end of the base 11;

[0070] A threading tube 13, which is connected to the top of the balance rotating rod 12, and the steel wire 6 passes through the threading tube 13;

[0071] The slide groove 14 is arranged on the inclined surfaces on both sides of the base 11;

[0072] A balancing block 15, the balancing block 15 is slidably connected in the slide slot 14;

[0073] The detection rod 16 has two ends which are respectively hinged to the upper part of the balancing rod 12 and the balancing block 15 , and an angle sensor is provided at the hinge to obtain the rotation angles of the two ends of the detection rod 16 .

[0074] The working principle and beneficial effects of the above technical solution are:

[0075] When adjusting the position of the self-balancing unit 5, the base 11 is pushed to slide on the machine 1 and locked. When the self-balancing unit 5 is in use, the steel wire 6 passes through the threading tube 13 and generates pressure on the inner wall of the threading tube 13; when the position of the steel wire 6 is offset, lateral pressure is generated on the threading tube 13, driving the threading tube 13 to rotate to one side; the threading tube 13 drives the balance rod 12 to rotate synchronously. On the one hand, the detection rods 16 on both sides of the balance rod 12 can provide a small amount of support to it, reduce the rotation of the balance rod 12, and help maintain the position of the steel wire 6; on the other hand, when the balance rod 12 rotates, it drives the balance block 15 to slide along the slide 14, and the angle sensors at both ends of the balance rod 12 detect the rotation angle of the conveying detection rod 16 to determine the accurate rotation angle of the detection rod 16; when there is a transmission gap between the base 11 and the machine 1, the influence of the force tilt of the base 11 on the detection result is eliminated, and the detection accuracy of the offset angle of the self-balancing unit 5 is improved, which is convenient for subsequent balance adjustment.

[0076] Embodiment 5:

[0077] like Figure 2-4 As shown, based on the above-mentioned embodiment 4, the self-balancing unit 5 further includes a first reset component, and the first reset component includes:

[0078] A first incomplete gear 17, wherein the first incomplete gear 17 is connected to the bottom end of the balancing rod 12, and the center of the first incomplete gear 17 coincides with the hinge point of the balancing rod 12;

[0079] A first gear 18, the first gear 18 is meshed and connected to the bottom end of the first incomplete gear 17;

[0080] A second gear 19, the second gear 19 is meshed and connected to the bottom end of the first gear 18;

[0081] The balance gear 21 is meshedly connected to the bottom end of the second gear 19, and an elastic reset member is disposed at the rotation center of the balance gear 21.

[0082] The working principle and beneficial effects of the above technical solution are:

[0083] When the balance lever 12 is deflected by the pressure of the steel wire 6, it needs to be reset to adjust the position of the steel wire 6. The first reset component is adopted, and when the balance lever 12 rotates, the first incomplete gear 17 is driven to rotate, the first incomplete gear 17 is meshed with the first gear 18 for transmission, the second gear 19 is meshed with the first gear 18 for transmission, and the balance gear 21 is meshed with the second gear 19 for transmission, thereby driving the balance gear 21 to rotate synchronously; the multi-gear transmission method can effectively reduce the transmission error and make the transmission more accurate; an elastic reset member is arranged at the center of the balance gear 21, and when the balance gear 21 rotates, the elastic reset member is stored with energy, so that it has a tendency to reset and rotate, and when the offset distance of the steel wire 6 is within the preset range, the elastic reset member can drive the balance gear 21 and the balance lever 12 to reset, and then quickly reset the steel wire 6 to achieve self-balancing adjustment.

[0084] Embodiment 6:

[0085] like Figure 4 As shown, on the basis of the above-mentioned embodiment 5, the balance gear 21 is configured as a gear ring structure, and the inner wall and the outer wall of the balance gear 21 are both provided with gear teeth, the outer wall of the balance gear 21 is meshed with the second gear 19, a center wheel 22 is concentrically arranged inside the balance gear 21, the center wheel 22 is rotatably connected to the base 11, and a coil spring 23 is provided at the connection, a plurality of planetary gears 24 are meshed and connected between the inner wall of the balance gear 21 and the center wheel 22, and the balance gear 21, the center wheel 22 and the planetary gears 24 form a planetary gear train.

[0086] The working principle and beneficial effects of the above technical solution are:

[0087] The balance gear 21, the center wheel 22 and the planetary gear 24 form a planetary gear train. When the balance gear 21 rotates, the center wheel 22 is driven to rotate through the planetary gear 24, thereby storing energy in the coil spring 23, which is an elastic reset member. When resetting, the coil spring 23 drives the center wheel 22 to rotate in the opposite direction under the action of elastic force, and drives the balance gear 21 to rotate in the opposite direction through the planetary gear 24. The design of the planetary gear train can improve the balance of torque transmission and reduce the relative slip between gears.

[0088] Embodiment 7:

[0089] like Figure 2-4 As shown, based on the above-mentioned embodiment 6, the self-balancing unit 5 further includes a second reset component, which is provided in two groups and respectively located on both sides of the base 11. The second reset component includes:

[0090] A second incomplete gear 25, the second incomplete gear 25 is rotatably connected to one side of the base 11, and the rotating shaft of the second incomplete gear 25 is connected to the output end of the motor;

[0091] A third gear 26, the third gear 26 is rotatably connected to the base 11 and meshes with the second incomplete gear 25;

[0092] The connecting rod 27 has two ends which are eccentrically hinged to the third gear 26 and the center wheel 22 respectively.

[0093] The working principle and beneficial effects of the above technical solution are:

[0094] The rotation angle of the balancing lever 12 is determined by the detection result of the angle sensor. When the rotation angle of the balancing lever 12 exceeds the preset value, or the balancing lever 12 cannot be completely reset, that is, the angle remains at a certain value after reset, the motor is started to drive the second incomplete gear 25 to rotate, the second incomplete gear 25 is meshed with the third gear 26 for transmission, and the third gear 26 drives the center wheel 22 to rotate through the connecting rod 27, assisting the center wheel 22 to reset, and then assisting the balancing lever 12 to reset, so that the steel wire 6 is restored to a state corresponding to the steel wire groove. The second reset assembly is set as two groups, which can adapt to the deflection of the steel wire 6 in different directions.

[0095] Embodiment 8:

[0096] like Figure 5-7 As shown, on the basis of the above-mentioned embodiment 4, a wire breaking prevention component is provided in the threading tube 13, and the wire breaking prevention component includes:

[0097] The hose 31 is concentrically arranged at the center of the threading tube 13, and the steel wire 6 passes through the hose 31; two fixing rings 32 are connected to both ends of the threading tube 13 to fix the ends of the hose 31;

[0098] The limiting pressure plate 33 is arranged in the groove at the top of the threading tube 13. A fixing plate 34 is arranged near the side of the groove on the threading tube 13. The limiting pressure plate 33 is hinged to the fixing plate 34. An end plate 35 is arranged near the end of the groove on the threading tube 13. The end plate 35 is connected to the limiting pressure plate 33 through a spring 36.

[0099] An electric telescopic rod is arranged on the side of the limiting pressure plate 33, and a limiting hole corresponding to the electric telescopic rod is arranged in the slot. When the electric telescopic rod is inserted into the limiting hole, the limiting pressure plate 33 is locked. A waist-shaped groove 37 is arranged on the top of the limiting pressure plate 33.

[0100] The working principle and beneficial effects of the above technical solution are:

[0101] The steel wire 6 is reset by the action of the threading tube 13, and is pulled by the threading tube 13. In the process of flattening the steel wire 6, it is subjected to the pulling force of the unwinding roller 2 and the winding roller 3, so there is a risk of wire breaking of the steel wire 6. In order to solve the above technical problems, an anti-breaking component is provided in the threading tube 13. When in use, the steel wire 6 is passed through the hose 31, and the steel wire 6 is closely attached to the bottom end of the inner wall of the hose 31, and then acts on the threading tube 13, ensuring that the threading tube 13 moves synchronously with the movement of the steel wire 31. A wire breakage detection component is provided on the flattening machine, for example, the wire breakage state is detected by means of pressure sensors provided on the unwinding roller 2 and the winding roller 3; when a wire breakage is detected, the electrically controlled telescopic rod on the limit pressure plate 33 is started to separate it from the limit hole, the limit of the limit plate 33 is released, and the limit pressure plate 33 rotates rapidly under the action of the spring 36; the limit pressure plate 33 is provided as an arc-shaped plate, and the curvature at each position is different with the hinge point as the center. When the limit pressure plate 33 is in the limit state, the compression amount of the hose 31 is small. When the limit pressure plate 33 rotates, the compression amount of the hose 31 increases, so that after the hose 31 is compressed and deformed, the upper part also fits on the surface of the steel wire 6, thereby clamping the steel wire 6 to prevent the steel wire 6 from falling off further.

[0102] Through the above-mentioned structural design, when the wire is not broken, the limit pressure plate 33 is in a locked state, and the top of the hose 31 is slightly deformed, which does not affect the feeding of the steel wire 6; when the wire is broken, the anti-wire breakage component is automatically started, the contact limit pressure plate 33 is locked, and the steel wire 6 is clamped to prevent further falling off; after the wire breakage problem is contacted, the limit pressure plate 33 can be manually rotated to the locked state and locked, and the wire breakage component can be reused, and the use effect is good.

[0103] Embodiment 9:

[0104] like Figure 5-8 As shown, on the basis of the above-mentioned embodiment 8, the anti-breaking assembly further includes: a limit clamping frame, the limit clamping frame is concentrically arranged between the threading tube 13 and the hose 31, and the limit clamping frame includes:

[0105] A first circular ring 41 and a second circular ring 42, both of which are connected to the inner wall of the threading tube 13; the second circular ring 42 is away from the limiting pressure plate 33 and rotates relative to the threading tube 13;

[0106] Support rods 43, four support rods 43 are connected between the first ring 41 and the second ring 42, and are arranged at a preset angle, and the connection between the support rods 43 and the ring is set as a ball joint;

[0107] The arc plate 44 is connected to the top of the second ring 42, and the arc plate 44 rotates relative to the arc groove on the threading tube 13;

[0108] The linkage rod 45 has two ends which are hinged to the arc plate 44 and the waist-shaped groove 37 respectively.

[0109] The working principle and beneficial effects of the above technical solution are:

[0110] When the anti-breaking assembly is not started, the limit clamping frame is in the initial state, the four support rods 41 are in a parallel state, the support rods 41 and the hose 31 are not in contact, and the movement of the steel wire 6 is not affected at this time, and the linkage rod 45 and the limit pressing plate 33 are at a preset angle. When the anti-breaking assembly is started, the limit pressing plate 33 rotates rapidly under the action of the spring 36, pulling one end of the linkage rod 45 to move, and the other end of the linkage rod 45 pulls the arc plate 44 to rotate along the arc groove of the threading tube 13, driving the second ring 43 to rotate, so that the second ring 42 and the first ring 41 are relatively deflected, and the linkage rod 45 is twisted to form a preset angle, pressing the hose 31 inward, and clamping the steel wire 6, further preventing the steel wire 6 from falling off, improving the anti-breaking performance of the flattening machine, and having higher safety.
