Description

Technical Field

[0001] The present invention relates to the technical field of continuous rolling and winding equipment for steel wires, and particularly to a steel wire rolling and winding equipment. Background Art

[0002] According to the requirements of different products, the preparation of steel wires usually includes billet selection, surface treatment, heat treatment, pre-annealing treatment, multi-pass rolling, lubrication and cooling, post-test treatment, post-annealing treatment, etc. In particular, in the continuous operation of rolling and winding of steel wires, existing equipment such as a steel wire rolling and winding equipment disclosed in Chinese Patent Document CN107413846A, includes a first vertical rolling mechanism, a first horizontal rolling mechanism, a second horizontal rolling mechanism, and a second vertical rolling mechanism that are fixedly arranged on the side of a support plate in sequence, and a winding mechanism formed downstream of an operation table, which automatically winds the rolled steel wire into a coil. However, especially when winding steel wires on a reel with a certain width, it is necessary to control the uniform winding along the axial width of the reel. For this, in the prior art, such as a cyclic guiding automatic uniform wire winding structure disclosed in CN105966989A, an additional cyclic guiding module and a motor are required. The motor drives the cyclic guiding module, and a reciprocating sliding slider is designed through the structural characteristics of a screw to perform cyclic uniform wire winding. However, since the winding distance of the steel wire changes at different width positions along the reel, the tension of the steel wire changes, resulting in difficult tension control in the continuous rolling and winding of the steel wire, and the design of the attached cyclic guiding module and motor is obviously not conducive to the efficiency of the entire continuous rolling and winding operation. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a steel wire rolling and winding equipment to solve the problem that it is difficult to perform automatic tension control simultaneously in the continuous operation of rolling and uniform winding of existing steel wires.

[0004] Based on the above purpose, the present invention provides a steel wire rolling and winding equipment, including a frame. A roll group is rotatably connected to the frame, and a winding reel is arranged at the rear end of the roll group for rotationally winding the steel wire: The frame includes a cross frame and a vertical frame arranged on one side of the cross frame. The roll group includes a front-pass extrusion roll and a rear-pass extrusion roll. The front-pass extrusion rolls are arranged opposite to each other up and down. The steel wire passes through the gap between the upper and lower front-pass extrusion rolls. A plurality of front-pass extrusion rolls are arranged at intervals transversely on the cross frame; The rear-pass extrusion roll is movably connected to the vertical frame and includes an upper rotating roll and a lower rotating roll arranged opposite to each other up and down. The roll shape of the lower rotating roll is designed as a circular shape, and the roll shape of the upper rotating roll is designed as an oval shape; A guiding roller is provided between the front-pass squeezing roller and the rear-pass squeezing roller. The steel wire is sequentially conveyed through the front-pass squeezing roller and the guiding roller, and passes through the gap between the upper rotating roller and the lower rotating roller. When the upper rotating roller rotates, it pushes the lower rotating roller to move up and down. A pushing roller device is provided between the rear-pass squeezing roller and the vertical frame, which is used to push the rear-pass squeezing roller to deflect forward and backward with its vertical diameter as the axis. When the pushing roller device pushes the rear-pass squeezing roller to a deflected position, the steel wire is wound at the front-end position or the rear-end position in the axial direction of the winding drum. When the lower rotating roller moves down to a low position state, and when the pushing roller device pushes the rear-pass squeezing roller to an intermediate position, the steel wire is wound at the intermediate position in the axial direction of the winding drum, and the lower rotating roller moves up to a high position state.

[0005] Preferably, a front bracket is fixedly connected to the vertical frame. An upright connecting frame is provided inside the rear-pass squeezing roller. The bottom end of the upright connecting frame is rotatably connected to the front bracket. The inner side of the upper rotating roller is connected with an upper roller shaft, and the inner side of the lower rotating roller is connected with a lower roller shaft. The upper roller shaft is rotatably connected to the upright connecting frame. A first slider is vertically slidably connected to the lower part of the upright connecting frame. The lower roller shaft is rotatably connected to the first slider. An elastic member is connected between the lower rotating roller and the front bracket.

[0006] Preferably, a transverse through-hole is provided on the vertical frame. The upper roller shaft sequentially passes through the upright connecting frame and the transverse through-hole, and is connected with a driving part for driving the upper roller shaft to rotate.

[0007] Preferably, a rear bracket is fixedly connected to the inner side of the vertical frame. The bottom end of the driving part is connected with a second slider, and the second slider is slidably connected to the rear bracket.

[0008] Preferably, a bottom bracket is provided at the bottom end of the lower rotating roller. The inner end of the bottom bracket is connected with a third slider, and the third slider is slidably connected to the upright connecting frame. The elastic member is connected between the bottom bracket and the front bracket.

[0009] Preferably, the pushing roller device includes a circular ring frame connected to the inner end of the upper rotating roller. A convex platform is provided on the vertical frame at a position on one side of the circular ring frame. The convex platform abuts against one side of the circular ring frame. When the circular ring frame rotates synchronously with the upper rotating roller, the rear-pass squeezing roller is pushed to deflect forward and backward by the change in the length of the position where the circular ring frame abuts against the convex platform.

[0010] Preferably, the convex platform is fixed to the upper end of the vertical frame, and a side roller is connected to one side of the convex platform and abuts against the middle position of the side end of the circular ring frame.

[0011] Preferably, a plurality of mesh holes are arranged on the outer circumference of the upper rotating roller, and a plurality of convex teeth are arranged on the outer circumference of the lower rotating roller. When the upper rotating roller rotates, the convex teeth are sequentially engaged in the mesh holes to drive the lower rotating roller to rotate synchronously.

[0012] Preferably, an elastic column is provided inside the upper rotating roller. The elastic column elastically protrudes outwards and is used to press against the passing steel wire. A detection sensor is provided on one side of the elastic column for detecting the distance that the elastic column protrudes outwards. An alarm is provided on the frame and is electrically connected to the detection sensor. When the detection sensor detects that the protruding distance of the elastic column is too long or too short, the alarm is triggered to give an alarm.

[0013] Preferably, the elastic columns are respectively located at the long-axis end and the short-axis end of the upper rotating roller. When the detection sensor detects that the protruding distances of the elastic columns at the long-axis end and the short-axis end differ too much, the alarm is triggered to give an alarm.

[0014] The beneficial effects of the present invention: A rolling mill group is rotatably connected to the frame. The rolling mill group includes a front-pass extrusion roller and a rear-pass extrusion roller. The rear-pass extrusion roller is movably connected to the vertical frame and includes an upper rotating roller and a lower rotating roller that are arranged oppositely up and down. The roller shape of the lower rotating roller is designed to be circular, and the roller shape of the upper rotating roller is designed to be elliptical. The steel wire is sequentially conveyed through the front-pass extrusion roller and the guiding roller and passes through the gap between the upper rotating roller and the lower rotating roller. When the elliptical upper rotating roller rotates, it pushes the lower rotating roller to move up and down. At the same time, a pushing roller device is provided between the rear-pass extrusion roller and the vertical frame for pushing the rear-pass extrusion roller to deflect back and forth along its vertical diameter as the axis. When the pushing roller device pushes the rear-pass extrusion roller to a deflected position, the steel wire is wound at the front-end position or the rear-end position along the axial direction of the winding drum. At this time, the lower rotating roller moves down to a low position state, so that the winding distance becomes longer, but the wire guiding distance of the lower rotating roller becomes shorter. When the pushing roller device pushes the rear-pass extrusion roller to an intermediate position, the steel wire is wound at the intermediate position along the axial direction of the winding drum. At this time, the lower rotating roller moves up to a high position state, so that the winding distance becomes shorter, and the wire guiding distance of the lower rotating roller becomes longer. During the continuous rolling and winding operation of the steel wire, the pushing roller device pushes the rear-pass extrusion roller to continuously deflect from front to back and then from back to front, so that the steel wire is evenly wound from front to back and then from back to front along the axial direction of the winding drum. And corresponding to the design of the elliptical upper rotating roller, the elliptical long-axis end and the elliptical short-axis end of the upper rotating roller sequentially and continuously rotate and press against the lower rotating roller, pushing the lower rotating roller to continuously move up and down reciprocally. Thereby, the wire guiding distance of the lower rotating roller changes correspondingly and continuously. Thus, while the rear-pass extrusion roller is normally rolling, uniform winding of the steel wire and automatic adaptive tension adjustment are achieved, and there is no need for redundant circulating guiding modules and motor settings, and the operation efficiency is higher.

[0021] The present invention is based on the existing main equipment structure for wire rolling and winding, including a frame, a rolling roll group is rotatably connected to the frame, a winding drum 1 is arranged at the rear end of the rolling roll group, the wire 2 is sequentially rolled by the rolling roll group of each pass and is rotatably wound by the rear winding drum 1. In particular, such as Figure 1 , Figure 2 , Figure 9As shown, the frame includes a horizontal frame 3 and a vertical frame 4 provided on one side of the horizontal frame 3. The roll set includes a front-pass extrusion roll 5 and a rear-pass extrusion roll 6. The front-pass extrusion rolls 5 are arranged oppositely up and down. The steel wire 2 passes through the gap between the upper and lower front-pass extrusion rolls 5. A plurality of front-pass extrusion rolls 5 are arranged transversely and spaced apart on the horizontal frame 3. The rear-pass extrusion roll 6 is movably connected to the vertical frame 4 and includes an upper rotating roll 61 and a lower rotating roll 62 arranged oppositely up and down. By designing the shape of the roll gap between the upper and lower extrusion rolls, such as circular, square, rectangular, triangular, elliptical, flat, trapezoidal, etc., it is used to roll the steel wire into a corresponding cross-sectional shape. For example, a steel wire with a circular shape, such as Figure 6 As shown, by designing the size change of the roll gap, the steel wire passing through is gradually extruded to change its diameter, and finally it is extruded and rolled into a steel wire with the target wire diameter. More particularly, the roll shape of the lower rotating roll 62 is designed to be circular, and the roll shape of the upper rotating roll 61 is designed to be elliptical. The elliptical upper rotating roll 61 does not affect its synchronous relative rotation with the lower rotating roll 62. The upper rotating roll 61 and the lower rotating roll 62 are in contact with each other up and down, and the roll gap between them is still designed as a circular hole, so as not to affect the extrusion and rolling of the passing steel wire. A guide roll 7 is provided between the front-pass extrusion roll 5 and the rear-pass extrusion roll 6. The steel wire 2 is sequentially transmitted through the front-pass extrusion roll 5 and the guide roll 7 and passes through the gap between the upper rotating roll 61 and the lower rotating roll 62. When the elliptical upper rotating roll 61 rotates, it naturally pushes the lower rotating roll 62 to move up and down. At the same time, a pushing roll device is provided between the rear-pass extrusion roll 6 and the vertical frame 4, which is used to push the rear-pass extrusion roll 6 to deflect back and forth around its vertical diameter as the axis, such as Figure 9 , Figure 11 As shown, when the pushing roll device pushes the rear-pass extrusion roll 6 to a deflected position, the steel wire 2 is wound at the front end position or the rear end position in the axial direction of the winding drum 1. At this time, the lower rotating roll 62 moves down to a low position state, so the winding distance becomes longer, but the wire guiding distance of the lower rotating roll 62 becomes shorter. When the pushing roll device pushes the rear-pass extrusion roll 6 to the middle position, such as Figure 1 , Figure 2 , Figure 10As shown, the steel wire 2 is wound at the middle position in the axial direction of the winding drum 1. At this time, the lower rotating roller 62 moves upward to a high position state, so that the winding distance becomes shorter, while the wire guiding distance of the lower rotating roller 62 becomes longer. In the continuous rolling and winding operation of the steel wire, the pushing roller device pushes the subsequent pass squeezing roller 6 to continuously deflect from front to back and then from back to front, so that the steel wire is evenly wound from front to back and then from back to front in the axial direction of the winding drum 1. And corresponding to the designed elliptical upper rotating roller 61, the long axis end and the short axis end of the ellipse of the upper rotating roller 61 continuously rotate and press against the lower rotating roller 62 in sequence, pushing the lower rotating roller 62 to continuously move up and down reciprocally. Thus, the wire guiding distance of the lower rotating roller 62 changes correspondingly continuously. Therefore, while the subsequent pass squeezing roller 6 is rolling normally, uniform winding of the steel wire and automatic adaptive tension adjustment are realized, and there is no need for redundant circulating guiding modules and motor settings, and the operation efficiency is higher.

[0022] In an embodiment of the present invention, as Figure 1 、 Figure 2 、 Figure 3 shown, a front bracket 8 is fixedly connected to the vertical frame 4. An inner side of the subsequent pass squeezing roller 6 is provided with a vertical connecting frame 9. A bottom end of the vertical connecting frame 9 is rotatably connected to the front bracket 8. Specifically, a bottom end of the vertical connecting frame 9 is connected with a cross plate 91. The bottom end of the cross plate 91 is rotatably connected to the front bracket 8 through a rotating shaft, which is beneficial for the subsequent pass squeezing roller 6 to stably deflect back and forth around its vertical diameter as an axis. An inner side of the upper rotating roller 61 is connected with an upper roller shaft 611. An inner side of the lower rotating roller 62 is connected with a lower roller shaft 621. The upper roller shaft 611 is rotatably connected to the vertical connecting frame 9. A first slider 10 is vertically slidably connected to a lower part of the vertical connecting frame 9. The lower roller shaft 621 is rotatably connected to the first slider 10. An elastic member 11 is connected between the lower rotating roller 62 and the front bracket 8. Thus, the lower rotating roller 62 is pushed upward by the elastic member 11, so that the lower rotating roller 62 presses against the upper rotating roller 61 and rotates relatively synchronously with the upper rotating roller 61, which is beneficial for efficient extrusion rolling.

[0023] In an embodiment of the present invention, as Figure 1 、 Figure 2 、 Figure 3 shown, a through opening 41 is formed in the vertical frame 4. The upper roller shaft 611 sequentially penetrates through the vertical connecting frame 9 and the through opening 41 and is connected with a driving part 12. The driving part 12 adopts existing structures such as a driving motor mechanically connected to a speed reducer, etc., for driving the upper roller shaft 611 to rotate and driving the upper rotating roller 61 to rotate.

[0024] In an embodiment of the present invention, as Figure 1 、 Figure 2 、 Figure 3As shown, a rear bracket 13 is fixedly connected to the inner side of the vertical frame 4. The bottom end of the driving part 12 is connected with a second slider 14, and the second slider 14 is slidably connected to the rear bracket 13. When the post-pass extrusion roller 6 deflects back and forth with its vertical diameter as the axis, the second slider 14 slides on the rear bracket 13, and the stable support and guiding deflection functions are realized by using the rear bracket 13 and the second slider 14.

[0025] In an embodiment of the present invention, as Figure 1 , Figure 2 , Figure 3 As shown, a bottom bracket 15 is provided at the bottom end of the lower rotating roller 62. Preferably, a roller 151 is rotatably connected inside the bottom bracket 15, and the roller 151 abuts against the outer bottom end of the lower rotating roller 62. The inner end of the bottom bracket 15 is connected with a third slider 16, and the third slider 16 is slidably connected to the vertical connecting frame 9. When the lower rotating roller 62 moves up and down, the first slider 10 and the third slider 16 slide up and down synchronously along the vertical connecting frame 9. The elastic member 11 is connected between the bottom bracket 15 and the front bracket 8. Specifically, the elastic member 11 can adopt existing elastic components such as springs and elastic telescopic rods, and is used to push the bottom bracket 15 upward.

[0026] In an embodiment of the present invention, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the push roller device includes a circular ring frame 17 connected to the inner end of the upper rotating roller 61. A convex platform 18 is provided on the vertical frame 4 at a position on one side of the circular ring frame 17, and the convex platform 18 abuts against one side of the circular ring frame 17. When the circular ring frame 17 rotates synchronously with the upper rotating roller 61, through the change in the length of the circular ring frame 17 in its own axial direction, the distance between the position where the circular ring frame 17 abuts against the convex platform 18 changes, thereby pushing the post-pass extrusion roller 6 to deflect back and forth. That is, the position of the convex platform 18 is fixed, and the distance between the outer end of the circular ring frame 17 along its circumferential circle and the inner side wall of the upper rotating roller 61 continuously changes, realizing the function of pushing the post-pass extrusion roller 6 to deflect back and forth.

[0027] In an embodiment of the present invention, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the convex platform 18 is fixed to the upper end of the vertical frame 4, and a side roller 181 is connected to one side of the convex platform 18. The side roller 181 abuts against the middle position of the side end of the circular ring frame 17. As Figure 5 shown, it is a side view of the circular ring frame 17, that is, the upper and lower ends of the circular ring frame 17 are long axis ends, and the middle two sides are short axis ends. As Figure 4 shown, it is a front view of the side roller 181 abutting against the circular ring frame 17. At this time, the side roller 181 abuts against the short axis end of the circular ring frame 17.

[0028] In an embodiment of the present invention, as Figure 7 , Figure 8 shown, a plurality of mesh holes 19 are arranged on the outer circumference of the upper rotating roller 61, and a plurality of convex teeth 20 are arranged on the outer circumference of the lower rotating roller 62. As another embodiment of the present invention, a plurality of mesh holes 19 can also be arranged on the outer circumference of the lower rotating roller 62, and a plurality of convex teeth 20 are arranged on the outer circumference of the upper rotating roller 61. When the upper rotating roller 61 rotates, the convex teeth 20 are sequentially engaged in the mesh holes 19 to drive the lower rotating roller 62 to rotate synchronously.

[0029] In an embodiment of the present invention, as Figure 1 , Figure 2 , Figure 8 , Figure 9 shown, an elastic column 21 is arranged inside the upper rotating roller 61. The elastic column 21 elastically extends outwards to press against the passing steel wire 2. A detection sensor is arranged on one side of the elastic column 21 to detect the distance that the elastic column 21 extends outwards. An alarm is arranged on the frame and is electrically connected to the detection sensor. When the detection sensor detects that the extension distance of the elastic column 21 is too long or too short, it indicates that the wire diameter of the steel wire 2 rolled deviates from the preset target, and the alarm is triggered to give an alarm.

[0030] In an embodiment of the present invention, as Figure 1 , Figure 2 , Figure 8 , Figure 9 shown, the elastic columns 21 are respectively located at the long axis end and the short axis end of the upper rotating roller 61. When the detection sensor detects that the extension distances of the elastic columns 21 at the long axis end and the short axis end differ too much, the alarm is triggered to give an alarm. The head end of the elastic column 21 is designed with an arc transition. When the elastic column 21 rotates with the upper rotating roller 61 to the position of the steel wire 2, the head end of the elastic column 21 is naturally pushed, so that part of the elastic column 21 retracts. The detection positions of the elastic columns 21 are only at the long axis end and the short axis end of the upper rotating roller 61, and the detection frequency is reasonable. And no matter whether the extension distance of the elastic column 21 detected by the detection sensor meets the expected range, as long as the detection sensor detects that the extension distances of the elastic columns 21 at the long axis end and the short axis end differ too much, it indicates that the tension change is too large when the steel wire 2 is wound at the middle position and the two ends of the winding drum 1, indicating that the adaptive adjustment of the tension does not meet the expectation, and the alarm is also triggered, so as to facilitate the staff to check, maintain or adjust devices such as the ring frame 17, the bottom bracket 15, and the elastic member 11 to achieve the expected tension adjustment effect.

[0031] Those of ordinary skill in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above, which are not provided in detail for the sake of brevity.
