Description

Technical Field

[0001] The invention relates to the technical field of straightening devices, and in particular to an ultra-fine steel wire straightening device with an adjustment function. Background Art

[0002] In the metal processing and manufacturing industries, steel wire is a thin and long metal wire made by drawing and processing metal materials. The continued use of steel wire is inseparable from the processing of the double twisting machine, which can twist multiple thin steel wires to form products such as ropes or cables that meet specific requirements. However, during the manufacturing process, the steel wire may bend or twist due to processes such as drawing and cutting. If these defects are directly twisted without straightening, they may cause quality problems in the final product. Therefore, before the double twisting machine twists the steel wire, in order to ensure that the steel wire used can meet the expected quality and performance requirements during the twisting process, the steel wire is usually straightened so that during the twisting process of the double twisting machine, the steel wire can better maintain uniformity, stability and reliability, thereby ensuring the quality of the final product.

[0003] Wire straightening refers to the use of special equipment to correct the wire to make it straight for subsequent processing and use. And because the wire has rebound force, when straightening, it is necessary to gradually reduce the downward pressure of the adjusting wheel on the straightener from the inlet side to the outlet side, so that the wire can be fully deformed and the original internal stress is destroyed. Otherwise, the wire is easy to deform again after straightening.

[0004] Existing wire straightening machines can often only extrude the wire in one direction and cannot completely straighten the wire. The wire needs to be straightened multiple times, which increases the workload of workers. Moreover, the quality of the wire straightening is not high, which affects the quality of subsequent processed products.

[0005] Chinese patent CN108856575B discloses a bearing pressure straightening wire straightening machine, including a support plate, a rotating rod, and a rotating plate. By rotating an adjusting sleeve, the adjusting threaded rod can adjust the horizontal distance between the first transverse straightening roller and the second transverse straightening roller through a movable plate and a support rod, so that workers can adjust the longitudinal extrusion distance and the transverse extrusion distance of the bearing pressure straightening wire straightening machine according to the specifications of the steel wire, thereby increasing the application scope of the bearing pressure straightening wire straightening machine.

[0006] However, when used, this patent first straightens the steel wire in a first direction (up and down direction) and then straightens it in a second direction (left and right direction). This straightening method will cause the steel wire to be easily twisted in the second direction under the action of two forces in the first direction after being straightened in the first direction. Similarly, after the steel wire is straightened in the second direction, it will be easily twisted in the first direction under the action of two forces in the second direction, resulting in poor quality of the steel wire after final straightening. Summary of the invention

[0007] The invention provides an ultra-fine steel wire straightening device with an adjustment function, so as to solve the problem that the existing straightening device is prone to twisting during the straightening process, thus affecting the quality of the steel wire after straightening.

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.

[0029] An embodiment of an ultra-fine steel wire straightening device with an adjustment function of the present invention is as follows Figures 1 to 6 shown.

[0030] An ultra-fine steel wire straightening device with an adjustment function comprises a bracket 100 and a plurality of adjustment groups 200. The bracket 100 has an inlet end 101 and an outlet end 102, and the inlet end 101 and the outlet end 102 are respectively located on both sides of the bracket 100 along a first direction, and the first direction is a horizontal direction. Figure 1 As shown, the first direction is the direction shown by the X-axis.

[0031] The plurality of adjustment groups 200 are all mounted on the bracket 100. The steel wire 300 can enter the plurality of adjustment groups 200 from the inlet end 101 and be sent out from the outlet end 102 after passing through the plurality of adjustment groups 200. The adjustment group 200 includes a first adjustment wheel 210, a second adjustment wheel 220, a third adjustment wheel 230 and a fourth adjustment wheel 240. The first adjustment wheel 210 and the third adjustment wheel 230 are respectively arranged on both sides of the steel wire 300 along the second direction. The second direction is perpendicular to the first direction and is a horizontal direction. Figure 1The second direction is the direction shown by the Y axis. The second adjustment wheel 220 and the fourth adjustment wheel 240 are respectively arranged on both sides of the steel wire 300 along the third direction, and the third direction is perpendicular to the first direction and the second direction respectively, and the third direction is a vertical direction.

[0032] A straightening space through which the steel wire 300 can pass is defined between the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240, and the first adjusting wheel 210 and the third adjusting wheel 230 can be rotatably arranged around the second direction, and the second adjusting wheel 220 and the fourth adjusting wheel 240 can be rotatably arranged around the third direction, so that when the steel wire 300 passes through the straightening space, the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 can be tangent to the steel wire 300.

[0033] Specifically, the first adjusting wheel 210 , the second adjusting wheel 220 , the third adjusting wheel 230 and the fourth adjusting wheel 240 are sequentially arranged on the bracket 100 along the first direction.

[0034] See attached Figure 3 As shown, the first adjusting wheel 210 is arranged on the right side of the steel wire 300, the second adjusting wheel 220 is arranged on the lower side of the steel wire 300, the third adjusting wheel 230 is arranged on the left side of the steel wire 300, and the fourth adjusting wheel 240 is arranged on the upper side of the steel wire 300. The upper side, lower side, left side, and right side are all referred to in the attached Figure 3 Up, down, left and right as shown in .

[0035] In this embodiment, a first adjusting wheel 210, a second adjusting wheel 220, a third adjusting wheel 230 and a fourth adjusting wheel 240 are arranged, and the first adjusting wheel 210 and the third adjusting wheel 230 are respectively arranged on both sides of the steel wire 300 along the second direction, and the second adjusting wheel 220 and the fourth adjusting wheel 240 are respectively arranged on both sides of the steel wire 300 along the third direction, that is, the second adjusting wheel 220 is inserted between the first adjusting wheel 210 and the third adjusting wheel 230, and the second adjusting wheel 220 is inserted between the second adjusting wheel 220 and the fourth adjusting wheel 240. The third adjusting wheel 230 is inserted, so that when the steel wire 300 passes through the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 from the incoming end 101, the four sides (upper side, lower side, left side and right side) of the steel wire 300 will be straightened simultaneously under the action of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240, which can reduce or even avoid the twisting of the steel wire 300 during the straightening process, thereby improving the quality of the steel wire 300 after straightening.

[0036] And by arranging that the first adjusting wheel 210 and the third adjusting wheel 230 can both rotate around the second direction, and the second adjusting wheel 220 and the fourth adjusting wheel 240 can both rotate around the third direction, the second adjusting wheel 220 interleaved between the first adjusting wheel 210 and the third adjusting wheel 230 can be adjusted along the state of the steel wire 300. Similarly, the third adjusting wheel 230 interleaved between the second adjusting wheel 220 and the fourth adjusting wheel 240 can also be adjusted along the state of the steel wire 300. The steel wire 300 is limited by this positioning method, so that the steel wire 300 can be straightened along the arrangement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 after entering the straightening space. The straightening space is more compact and only needs to be unloaded once, thereby reducing the fatigue of the steel wire 300.

[0037] In this embodiment, the first adjusting wheel 210 includes an adjusting shaft 211 and a roller 212, the adjusting shaft 211 is mounted on the bracket 100, the roller 212 is rotatably mounted on the adjusting shaft 211 around its own axis, and the steel wire 300 can slide along the roller 212. The structures of the second adjusting wheel 220, the second adjusting wheel 220 and the fourth adjusting wheel 240 are the same as the structure of the first adjusting wheel 210.

[0038] Specifically, a limiting groove is provided on the roller 212, and the steel wire 300 can slide along the limiting groove.

[0039] In this embodiment, an ultra-fine steel wire straightening device with an adjustment function also includes four pressure rods 110, and the four pressure rods 110 are evenly distributed on the bracket 100 around a first direction. The first adjustment wheel 210, the second adjustment wheel 220, the third adjustment wheel 230 and the fourth adjustment wheel 240 are respectively arranged on the four pressure rods 110, and the four pressure rods 110 can rotate around the first reference axis respectively, so that the displacement of the first adjustment wheel 210, the second adjustment wheel 220, the third adjustment wheel 230 and the fourth adjustment wheel 240 approaching the steel wire 300 from the side of the input end 101 to the side of the output end 102 gradually decreases, and the direction of the first reference axis is perpendicular to the direction of the corresponding pressure rod 110.

[0040] In this embodiment, an ultra-fine steel wire straightening device with an adjustment function further includes a rotating ring 400, which is coaxially arranged with the bracket 100, and can be rotatably arranged on the side of the bracket 100 close to the inlet end 101 around the first direction, and the rotating ring 400 is located on the side of the four pressure rods 110 away from the steel wire 300 in the second direction, and the inner end of the rotating ring 400 is evenly distributed with four adjustment sections 410, and the four adjustment sections 410 are arranged one by one with the four pressure rods 110. The adjustment section 410 has a head end 411 and a tail end 412, and the head end 411 extends around the first direction to the tail end 412, and the head end 411 is located on the side of the tail end 412 away from the steel wire 300 along the second direction. In the initial state, the head end 411 of each adjustment section 410 contacts the corresponding pressure rod 110.

[0041] Furthermore, the rotating ring 400 and the bracket 100 are locked by bolts 420 .

[0042] In this embodiment, by setting the rotating ring 400 and the pressure rod 110 to cooperate, when it is necessary to adjust the distance from the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 to the steel wire 300 from the side of the inlet end 101 to the side of the outlet end 102, it is only necessary to manually rotate the rotating ring 400. When the rotating ring 400 rotates, the adjusting section 410 on it will cause the side of the inlet end 101 of the four pressure rods 110 to be respectively relative to the side of the outlet end 102. Rotating around the first reference axis, the four pressure rods 110 are all tilted, and then the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 on the four pressure rods 110 are respectively driven to move toward the side close to the steel wire 300, so that the displacement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 from the side of the inlet end 101 to the side of the outlet end 102 gradually decreases. That is to say, the displacement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 on the side of the inlet end 101 toward the side close to the steel wire 300 is the largest, and the displacement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 on the side of the outlet end 102 toward the side close to the steel wire 300 is the smallest, so that the steel wire 300 can be fully deformed and the original internal stress is destroyed.

[0043] That is, by setting the rotating ring 400, when in use, it is only necessary to rotate the rotating ring 400 to achieve synchronous adjustment of the four pressure rods 110, and then adjust the first adjustment wheel 210, the second adjustment wheel 220, the third adjustment wheel 230 and the fourth adjustment wheel 240 correspondingly set through the four pressure rods 110, and change the displacement of the first adjustment wheel 210, the second adjustment wheel 220, the third adjustment wheel 230 and the fourth adjustment wheel 240 from the side of the incoming line end 101 to the side of the outgoing line end 102 to the steel wire 300. The operation is simple, and the synchronous adjustment of the four pressure rods 110 can ensure that the inclination of the four pressure rods 110 is consistent, thereby improving the accuracy of straightening.

[0044] In this embodiment, an ultra-fine steel wire straightening device with an adjustment function further includes two mounting plates 500 , and the two ends of the bracket 100 along the first direction are fixedly mounted on the two mounting plates 500 respectively.

[0045] Specifically, the bracket 100 includes four support rods 103 and two support rings 104. The two support rings 104 are respectively fixedly mounted on two mounting plates 500. The four support rods 103 are all arranged along the first direction. The four support rods 103 are evenly distributed around the first direction between the two support rings 104. The pressure rod 110 is installed on the support rod 103 through a first elastic member, and the first elastic member is a spring.

[0046] Four swing grooves are provided on the support ring 104 near the side of the inlet terminal 101, and four hinged columns 111 are supported on the support ring 104 near the side of the outlet terminal 102. Four pressure rods 110 are arranged in a one-to-one correspondence with the four swing grooves and the four hinged columns 111. One end of the pressure rod 110 along the first direction is installed in the swing groove, and the other end of the pressure rod 110 along the first direction is rotatably connected to the hinged column 111, and the direction of the first reference axis is the axis direction of the hinged column 111. The first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 are connected to the corresponding pressure rods 110 after passing through their corresponding support rods 103 respectively.

[0047] The first adjusting wheel 210 and the third adjusting wheel 230 are provided with a first driving member, and the first driving member is used to drive the first adjusting wheel 210 and the third adjusting wheel 230 to rotate respectively around the second direction. The second adjusting wheel 220 and the fourth adjusting wheel 240 are both provided with a second driving member, and the second driving member is used to drive the second adjusting wheel 220 and the fourth adjusting wheel 240 to rotate respectively around the third direction. The first driving member and the second driving member are both motors.

[0048] More specifically, the two support rings 104 are fixedly connected to the mounting plate 500 via the annular hoops 130 .

[0049] In combination with the above embodiments, the specific working process is as follows:

[0050] Before straightening, the rotating ring 400 is in the initial state, the pressure rod 110 contacts the head end 411 of the corresponding adjustment section 410, and then the steel wire 300 is sent into the straightening space from the side of the inlet end 101 and sent out from the side of the outlet end 102. Subsequently, the rotating ring 400 is rotated according to the characteristics of the steel wire 300 to be straightened, and the adjusting section 410 on the rotating ring 400 is used to cause one end of the pressure rod 110 corresponding to the adjusting section 410 to swing in the swing groove. At this time, the other end of the pressure rod 110 swings relative to the hinge column 111, so that the entire pressure rod 110 is tilted, and then the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 thereon are respectively driven by the four pressure rods 110 to move toward the side close to the steel wire 300, so that the displacement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 approaching the steel wire 300 from the side of the inlet end 101 to the side of the outlet end 102 gradually decreases. That is, the displacement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 on the side of the incoming wire end 101 toward the side close to the steel wire 300 is the largest, and the displacement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 on the side of the outgoing wire end 102 toward the side close to the steel wire 300 is the smallest, so that the steel wire 300 can be fully deformed to destroy the original internal stress.

[0051] Then, the first driving member and the second driving member are started, and the first driving member drives the first adjusting wheel 210 and the third adjusting wheel 230 to rotate respectively around the second direction, and the second driving member drives the second adjusting wheel 220 and the fourth adjusting wheel 240 to rotate respectively around the third direction. The rotation directions of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 are changed, so that the second adjusting wheel 220 interspersed between the first adjusting wheel 210 and the third adjusting wheel 230 can be adjusted along the state of the steel wire 300. Similarly, the third adjusting wheel 230 interspersed between the second adjusting wheel 220 and the fourth adjusting wheel 240 can also be adjusted along the state of the steel wire 300. The steel wire 300 is limited by this positioning method, so that the steel wire 300 can be straightened along the arrangement of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 after entering the straightening space.

[0052] After the rotating ring 400 is rotated to a suitable position, the rotating ring 400 and the bracket 100 are locked by using the bolt 420 , and then the steel wire 300 is pulled out of the straightening space from the side of the outlet end 102 .

[0053] When the steel wire 300 passes through the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240 from the incoming end 101, the four sides (upper side, lower side, left side and right side) of the steel wire 300 will be straightened simultaneously under the action of the first adjusting wheel 210, the second adjusting wheel 220, the third adjusting wheel 230 and the fourth adjusting wheel 240, which can reduce or even avoid the twisting of the steel wire 300 during the straightening process and improve the quality of the steel wire 300 after straightening.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
