Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of straightening equipment, in particular to a straightening device for cable production and a use method thereof. BACKGROUND

[0002] The existing straightening device for cable production usually adopts a multi-roller straightening machine for straightening. The core principle of the multi-roller straightening machine is to form a continuous curved path through a plurality of groups of staggered straightening rollers. When the cable passes through, the repeated bending of the plurality of groups of straightening rollers can effectively eliminate the internal stress generated by the bending state, and finally achieve a flat state.

[0003] In the cable production process, there is a situation of winding the cable on a winding drum for storage. The cable is prone to internal stress in a long-term curved state. During the process of gradually releasing the cable from the outer side of the winding drum layer by layer, the curvature of the cable gradually increases, representing that the bending degree of the cable gradually increases. Therefore, the internal stress to be eliminated will gradually increase layer by layer. However, when the existing technology adopts a multi-roller straightening method, the height of the straightening roller is only adjusted according to the average diameter and the number of layers of the winding drum during the winding change. This operation method cannot adjust the straightening effect according to the real-time curvature of the cable, and is prone to cause the situation that the cable in the inner layer of the winding drum cannot be straightened due to small straightening degree. If direct processing is performed on the non-straight cable, it will cause uneven thickness, eccentricity and other defects of the insulation or sheath, and seriously affect the processing quality of the cable.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application.

The present application is in no way limited to any specific configuration and algorithm set forth below, but covers any modification, replacement, and improvement of elements, components, and algorithms without departing from the spirit of the present application. In the accompanying drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessary obscuring of the present application.

[0037] Embodiment 1, with reference to Figures 1-8 For the first embodiment of the present application, a straightening device for cable production is provided, which comprises a frame 1 and a reel 2, a straightening assembly, and a driving assembly arranged on the frame 1. The straightening assembly comprises a first mounting plate 13 fixed on the frame 1, a plurality of lower straightening rollers 44 rotatably connected to the first mounting plate 13, and a plurality of first sliding carriages 41 slidably connected to the first mounting plate 13. Each first sliding carriage 41 is rotatably connected to an upper straightening roller 42 on one side, and the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44 are arranged alternately.

[0038] The first slide 41 is fixedly installed with a slide rod 48 on the other side, and the outer side of the slide rod 48 farthest from the winding drum 2 is rotatably connected with a rotating plate 47, the rotating plate 47 is provided with a guide groove 471, the rest of the slide rods 48 are slidably connected in the guide groove 471, and one end of the slide rod 48 closest to the winding drum 2 is fixedly installed with a sliding block 49; the rack 1 is fixedly installed with a fixed rod 12, the outer side of the fixed rod 12 is rotatably sleeved with a threaded cylinder 45 which penetrates the sliding block 49, and the outer side of the threaded cylinder 45 is coaxially fixed with a gear 46;

[0039] The rack 1 is slidably connected with a sliding seat 32, and the rack 1 is vertically slidably connected with a lifting frame 3 below the winding drum 2, the lifting frame 3 is rotatably connected with a top roller 31, the lifting frame 3 is fixedly installed with a spring 34 between the bottom of the lifting frame 3 and the top of the rack 1, and the lifting frame 3 is rotatably connected with a connecting rod 33 between the lifting frame 3 and the sliding seat 32. The sliding seat 32 is fixedly installed with a rack 36, and the rack 36 and the gear 46 are in meshing connection.

[0040] The rack 1 is provided with a sliding groove 11, and the sliding seat 32 is fixedly installed with a protruding block which is slidably connected in the sliding groove 11.

[0041] The lifting frame 3 is fixedly installed with a guide rod 35 which slidably penetrates the rack 1, and the spring 34 is sleeved on the outer side of the guide rod 35.

[0042] The driving assembly comprises a second mounting plate 14 fixed to the rack 1 and a driving roller 5 rotatably connected to the second mounting plate 14, the second mounting plate 14 is slidably connected with a second slide 51, one side of the second slide 51 is rotatably connected with a pressing roller 52, and the pressing roller 52 is located directly above the driving roller 5.

[0043] The second slide 51 and the top of the first slide 41 farthest from the winding drum 2 are fixedly installed with an adjusting plate 4, the top of the threaded cylinder 45 is rotatably connected with the adjusting plate 4, and the rack 1 is fixedly installed with a hydraulic push rod 43, and the telescopic end of the hydraulic push rod 43 is fixedly connected with the adjusting plate 4.

[0044] During use, first, one end of the cable wound on the winding drum 2 is pulled out and passes between the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44 of the straightening assembly, then the cable passes between the driving roller 5 and the pressing roller 52 of the driving assembly, then the hydraulic push rod 43 is started to retract the telescopic end to drive the adjusting plate 4 to descend, the adjusting plate 4 drives the second slide 51 to descend, so that the adjusting plate 4 drives the pressing roller 52 to move towards the driving roller 5, and the pressing roller 52 and the driving roller 5 press the cable;

[0045] At the same time, the elastic force of the spring 34 in the compressed state makes the top end of the top roller 31 on the lifting frame 3 always contact the bottom of the cable on the winding drum 2, and at this time, there is a specific angle between the center line of the plurality of upper straightening rollers 42 and the center line of the plurality of lower straightening rollers 44, so that a continuous curved path is formed between the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44, and then the driving roller 5 is driven to rotate, so that the cable moves with the driving roller 5 by relying on the friction between them, thereby gradually pulling the cable out of the winding drum 2, and the cable moves along the curved path between the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44, so that the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44 repeatedly bend the cable, thereby causing the cable to be plastically deformed to a certain extent, effectively eliminating the internal stress generated by the bending state, and finally the cable is straightened.

[0046] Then, as the cable outside the winding drum 2 is pulled out layer by layer, when the outermost cable on the winding drum 2 is completely pulled out, the position of the bottom of the cable on the winding drum 2 is raised, at this time the curvature of the cable increases, the elastic force of the spring 34 in the compressed state pushes the lifting frame 3 to move upward, at the same time the guide rod at the bottom of the lifting frame 3 slides on the rack 1, ensuring the vertical upward movement of the lifting frame 3, so that the lifting frame 3 drives the top roller 31 to move upward, so that the top end of the top roller 31 again contacts the bottom of the cable on the winding drum 2. When the lifting frame 3 moves upward, the lifting frame 3 pulls the sliding block 32 to move along the sliding groove 11 towards the winding drum 2 through the rotating connecting connecting rod 33, so that the sliding block 32 drives the rack 36 to move towards the winding drum 2, and through the meshing transmission of the rack 36 and the gear 46, the gear 46 drives the threaded cylinder 45 to rotate, and then the sliding block 49 moves downward along the threaded cylinder 45, because the first sliding frame 41 farthest from the winding drum 2 is fixed with the adjusting plate 4, the sliding rod 48 farthest from the winding drum 2 cannot move up and down, so that the sliding rod 48 connected with the sliding block 49 drives the rotating plate 47 to rotate around the sliding rod 48 farthest from the winding drum 2 through the guide groove 471, so that the rotating plate 47 pushes the plurality of sliding rods 48 through the guide groove 471 to make the corresponding first sliding frame 41 move downward, thereby driving all the upper straightening rollers 42 except the upper straightening roller 42 farthest from the winding drum 2 to move downward by a certain distance, so that the angle between the center line of the plurality of upper straightening rollers 42 and the center line of the plurality of lower straightening rollers 44 increases, thereby increasing the degree of plastic deformation of the cable during straightening. With the layer-by-layer pulling out of the cable, the curvature of the outermost cable of the winding drum 2 gradually increases, so that the lifting frame 3 gradually moves upward under the elastic force of the spring 34, so that the straightening assembly can adjust the straightening degree of the cable in real time according to the curvature of the outermost cable of the winding drum 2, and ensure the straightening effect of the cable.

[0047] In addition, the preferred gear 46 is selected to be longer, so that when the adjusting plate 4 drives the threaded cylinder 45 and the gear 46 outside the threaded cylinder 45 to rise and fall when adjusting the cable of different diameters, the longer gear 46 can always be engaged with the rack 36, so that the straightening degree can be adjusted in real time according to the curvature of the outermost cable of the reel 2 when the cable of different diameters is compressed.

[0048] Embodiment 2, refer to Figures 1-6 As a second embodiment of the present application, the difference between this embodiment and the first embodiment is that:

[0049] One side of the second mounting plate 14 is fixedly provided with a motor 53, an output shaft of the motor 53 is fixedly connected with one end of the driving roller 5, the rack 1 is provided with a battery box 54 and a sliding rheostat 55, the sliding rheostat 55 is provided with a sliding seat for adjusting resistance, the motor 53, the battery box 54 and the sliding rheostat 55 are sequentially connected with a wire 56.

[0050] The fixed frame 37 is fixedly installed on the sliding seat 32, one end of the fixed frame 37 is fixedly connected with the sliding seat on the sliding rheostat 55.

[0051] During use, as the cable outside the reel 2 is pulled out layer by layer, the curvature of the cable outside the reel 2 gradually increases, and the bending degree of the cable gradually increases, so that the required straightening force increases and the required straightening time also needs to be prolonged, therefore, when the outermost cable on the reel 2 is pulled out completely, the curvature of the outermost cable on the reel 2 increases, the position of the cable at the bottom of the reel 2 rises, and the elastic force of the spring 34 in the compressed state pushes the lifting frame 3 and the top roller 31 to move upward, the lifting frame 3 pulls the sliding seat 32 to move along the sliding groove 11 towards the reel 2 through the rotating connecting connecting rod 33, so that the sliding seat 32 drives the fixed frame 37 to move synchronously while driving the rack 36 to move, so that the fixed frame 37 drives the sliding seat on the sliding rheostat 55 to move, so that the resistance of the circuit connected to the sliding rheostat 55 increases, so that the current passing through the motor 53 decreases under the condition that the total voltage of the battery box 54 is unchanged, so that the rotating speed of the motor 53 decreases, and further the rotating speed of the driving roller 5 driven by the motor 53 decreases, so that the moving speed of the cable moving with the driving roller 5 decreases, so as to prolong the straightening time of the cable with larger curvature in the inner layer, and ensure the straightening effect of the cable.

[0052] The remaining structure is the same as that of embodiment 1.

[0053] Embodiment 3, refer to Figures 1-3 and Figures 9-10 As a third embodiment of the present application, the difference between this embodiment and the second embodiment is that:

[0054] The fixed seat 15 is fixedly connected to the rack 1, and the movable seat 23 is slidably connected to the rack 1, and the fixed seat 15 and the movable seat 23 are each provided with a guide assembly, and the two guide assemblies each include two groups of guide rollers 6 arranged in a cross shape and rotatably arranged.

[0055] The rack 1 is provided with a cross rod sliding through the movable seat 23 and a reciprocating screw rod 24, the reciprocating screw rod 24 is provided with a reciprocating groove 241, the reciprocating screw rod 24 and one end of the winding drum 2 are coaxially fixedly provided with a belt pulley 22, and the two belt pulleys 22 are transmissionally connected through a belt 21, and the movable seat 23 is fixedly provided with a sliding column 231 which is slidably matched in the reciprocating groove 241.

[0056] In use, after the cable is pulled out from the winding drum 2, the cable end is sequentially threaded through the guide assemblies on the movable seat 23 and the fixed seat 15, and the cable passes through the middle part of the two groups of guide rollers 6 arranged in a cross shape and rotatably arranged, and the rotatably arranged guide rollers 6 can effectively reduce the friction with the cable;

[0057] In addition, the guide assembly on the fixed seat 15 enables the cable to smoothly enter the straightening assembly, avoiding the cable from deviating in the curved path between the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44;

[0058] In addition, the guide assembly on the movable seat 23 can ensure that the cable is gradually discharged from the outer side of the winding drum 2, and when the cable is pulled out by the compression roller 52 and the driving roller 5, the winding drum 2 is rotated by the cable, thereby driving the belt pulley 22 at the end of the winding drum 2 to rotate, and then driving the other belt pulley 22 to rotate through the belt 21, so that the winding drum 2 and the reciprocating screw rod 24 are synchronously rotated, the reciprocating groove 241 is a closed spiral track formed by two thread grooves with the same pitch and opposite rotation directions connected through a transition curve, when the reciprocating screw rod 24 rotates, the reciprocating groove 241 on the reciprocating screw rod 24 pushes the sliding column 231 to make the movable seat 23 reciprocate along the reciprocating screw rod 24 and the cross rod, so that the guide assembly on the movable seat 23 drives the cable to move along with the position of the cable pulled out from the winding drum 2, avoiding the cable between the winding drum 2 and the guide assembly on the movable seat 23 from deviating, thereby avoiding the cable from overlapping during the discharging process, and further avoiding affecting the movement of the top roller 31 and the adjustment of the straightening degree.

[0059] The remaining structure is the same as that of the structure of the second embodiment.

[0060] Referring to Figures 1-10 The present application provides a method for using a straightening device for cable production, comprising the following steps:

[0061] Step one: pull one end of the cable wound on the winding drum 2 out and through the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44 of the straightening assembly, then make the cable pass through the driving assembly and make the driving assembly compress the cable;

[0062] Step two: the spring 34 makes the top roller 31 top end of the lifting frame 3 from the cable bottom of the drum 2, and at this time the center line of the plurality of upper straightening rollers 42 and the center line of the plurality of lower straightening rollers 44 exist a certain angle, then start the drive assembly to gradually pull the cable from the drum 2, when the cable moves along the curved path between the plurality of upper straightening rollers 42 and the plurality of lower straightening rollers 44, so that the cable produces a certain degree of plastic deformation, thereby being straightened;

[0063] Step three: the cable outside the drum 2 is pulled out layer by layer, when the outermost cable on the drum 2 is pulled out, the cable bottom position on the drum 2 is raised, the spring 34 pushes the lifting frame 3 to move the top roller 31 upwards, so that the top roller 31 top end again touches the cable bottom on the drum 2, while the lifting frame 3 moves upwards, the slide 32 is pulled to move through the connecting rod 33, thereby driving the rack 36 to move, the screw cylinder 45 is rotated through the meshing transmission of the rack 36 and the gear 46, thereby the slider 49 moves downwards along the screw cylinder 45, the slide rod 48 connected with the slider 49 drives the rotating plate 47 to rotate around the slide rod 48 farthest from the drum 2 through the guide groove 471, so that the angle between the center line of the plurality of upper straightening rollers 42 and the center line of the plurality of lower straightening rollers 44 increases, thereby increasing the degree of plastic deformation during straightening, so as to adjust the straightening degree in real time according to the curvature of the outermost cable of the drum 2.

Both the fixed seat and the movable seat are provided with guide components. Each of the two guide components includes two sets of guide rollers arranged in a grid pattern and rotatably disposed.

9. A straightening device for cable production according to claim 8, characterized in that: The frame is provided with a crossbar that slides through the moving seat and a reciprocating screw. The reciprocating screw is provided with a reciprocating groove. The reciprocating screw and one end of the drum are both fixed with pulleys on the same axis, and a belt is connected between the two pulleys for transmission. A sliding column that slides in the reciprocating groove is fixedly installed on the moving seat.

10. A method of using the straightening device for cable production as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Pull one end of the cable wound on the drum and pass it between the upper and lower straightening rollers of the straightening assembly. Then, pass the cable through the drive assembly and press the cable with the drive assembly. Step 2: The spring force causes the top roller on the lifting frame to contact the bottom of the cable on the drum from below. At this time, there is a specific angle between the center line of the multiple upper straightening rollers and the center line of the multiple lower straightening rollers. Then, the drive assembly is activated to gradually pull the cable out of the drum. As the cable passes between the multiple upper and lower straightening rollers, it moves along the bending path, causing the cable to undergo a certain degree of plastic deformation, thereby straightening it. Step 3: The cables on the outer side of the drum are pulled out layer by layer. When the outermost layer of cables on the drum is completely pulled out, the bottom position of the cables on the drum rises. The spring force pushes the lifting frame to move the top roller upward, so that the top of the top roller contacts the bottom of the cables on the drum again. At the same time as the lifting frame moves upward, the connecting rod pulls the slide block to move, thereby driving the rack to move. Through the meshing transmission of the rack and gear, the threaded drum rotates, which in turn causes the slider to move downward along the threaded drum. The slide rod connected to the slider drives the rotating plate to rotate around the slide rod that is farthest from the drum through the guide groove. This increases the angle between the center line connecting the multiple upper straightening rollers and the center line connecting the multiple lower straightening rollers, thereby increasing the degree of plastic deformation during straightening. The straightening degree is adjusted in real time according to the curvature of the outermost layer of cables on the drum.
