Description

Technical Field

[0001] The invention relates to the field of aluminum wire production, and in particular to high-purity aluminum wire drawing equipment. Background Art

[0002] As is known, aluminum wire drawing refers to the process of making aluminum material into slender aluminum wire through a stretching process. The aluminum rod with surface treatment is drawn through a series of drawing dies by a drawing machine. Each drawing will reduce the diameter of the aluminum wire by a certain proportion, which is called the drawing pass reduction rate. During the drawing process, the aluminum wire may break. After the aluminum wire breaks, the rotating wheel will continue to rotate, which makes it easy for the broken aluminum wire to be entangled on the rotating shaft of the rotating wheel. It is troublesome to remove the aluminum wire from the rotating shaft.

[0003] For example, the Chinese patent document with publication number CN116748319A, publication date 2023-09-15, and titled "A kind of aluminum-magnesium alloy wire drawing device and its drawing method", includes a fixed plate fixed inside the chassis, a slide rail is fixedly installed above the fixed plate, and a first broken wire clamping assembly and a second broken wire clamping assembly are slidably connected above both ends of the slide rail; a tensioning wheel connected to the chassis through a rotating shaft is arranged at the upper position between the first broken wire clamping assembly and the second broken wire clamping assembly; when the aluminum-magnesium alloy wire is broken, the movable frame loses the restraint of the wire, and at this time the pushing spring is quickly released according to its own elasticity, and the driving connecting member pushed by the elastic force drives the sliding bracket to slide to one side along the sliding cylinder, and the broken wire clamping assembly is quickly flipped downward under the obstruction of the stopper, thereby clamping the aluminum-magnesium alloy wire in the sliding bracket, which can prevent the aluminum-magnesium alloy wire from being entangled on the transition wheel or the rotating wheel when the equipment is broken. Damage to the equipment.

[0004] Including the above-mentioned shortcomings of the prior art, after the aluminum wire breaks, although the stopper can clamp the aluminum wire in the sliding bracket, the rotary wheel is always in a rotating state.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] In the description of the present invention, it is necessary to understand that Figure 3 The middle slide bar 20 is on the left relative to the inner ring 1601, and vice versa. Figure 3 The position of the middle connecting column 17 relative to the inner ring 1601 is above, and vice versa. The terms "center", "longitudinal", "lateral", "length", "width", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] Reference Figure 1-9A high-purity aluminum wire drawing device provided by an embodiment of the present invention comprises a vertical plate 1 and a tensioning assembly arranged on the vertical plate 1 for providing the tensioning force required for the aluminum wire during the drawing process, a rotating wheel 2 is rotatably arranged on the vertical plate 1, the rotating wheel 2 comprises an inner disk 201 and an outer ring 202 rotatably arranged on the inner disk 201, and a connecting piece is arranged on the vertical plate 1 for preventing the inner disk 201 and the outer ring 202 from rotating relative to each other; a wire breaking protection mechanism is also arranged on the vertical plate 1, and after the aluminum wire breaks, the wire breaking protection mechanism is used to drive the connecting piece away from the rotating wheel 2 during the process of fixing the aluminum wire.

[0037] Specifically, the vertical plate 1 is preferably a vertically arranged rectangular plate-shaped structure, the tensioning assembly can be a sliding bracket that is arranged by rotation, and an elastic member is arranged on the sliding bracket, and the sliding bracket has a tendency to rotate through the elastic member to provide the tensioning force required for the aluminum wire, and a bracket is arranged on the vertical plate 1, and the rotating wheel 2 is rotatably connected to the bracket, and the rotating wheel 2 can be driven by a structure that provides a rotating force such as a motor, and the rotation of the rotating wheel 2 is used to provide power for conveying the aluminum wire and adjust the direction of the aluminum wire. The aluminum wire is wound around the rotating wheel 2 and the tensioning assembly and other structures, and passes through the wire drawing die, and then the diameter of the aluminum wire is changed through the drawing die to complete the drawing process of the aluminum wire. This is a prior art and will not be described in detail. For details, please refer to the patent document with publication number CN116748319A. One of the core innovations of the embodiment of the present invention is that the rotating wheel 2 is divided into an inner disk 201 and an outer ring 202 that are rotatably connected to each other, and A connecting piece is provided between the inner disk 201 and the outer ring 202 to prevent the two from rotating relative to each other. The wire breaking protection mechanism can be a cooperation structure of a pressure sensor and an electric push rod. When the pressure sensor senses that the tensioning force of the tensioning assembly is abnormal, an actuator is driven by the electric push rod to compress the aluminum wire to prevent the aluminum wire from continuing to move. The purpose of such a setting is that during the aluminum wire drawing process, the aluminum wire is wound around the outer ring 202 of the rotary wheel 2, and the inner disk 201 can drive the outer ring 202 to rotate synchronously under the action of the connecting piece. After the aluminum wire breaks, the wire breaking protection mechanism fixes the aluminum wire and drives the connecting piece away from the rotary wheel 2. Due to the lack of the connecting function of the connecting piece, the inner disk 201 and the outer ring 202 can rotate relative to each other at this time, that is, at this time, the kinetic energy of the inner disk 201 can hardly be transmitted to the outer ring 202, so that the aluminum wire cannot be continuously conveyed, so as to minimize the accumulation and entanglement of the aluminum wire.

[0038] Preferably, the tensioning assembly includes a sliding seat 3 and a tensioning wheel 4 rotatably disposed on the sliding seat 3 , a sliding groove 5 is opened on the vertical plate 1 , the sliding seat 3 is slidably connected to the sliding groove 5 , and a first spring 6 is disposed between the sliding seat 3 and the sliding groove 5 . Specifically, a protrusion 7 is provided on the vertical plate 1, and the slide groove 5 is arranged vertically on the protrusion 7. One end of the first spring 6 is fixedly connected to the inner wall of the slide groove 5, and the other end is fixedly connected to the sliding seat 3. Two guide wheels 8 are arranged in a triangle between the two guide wheels 8 and the tensioning wheel 4. The aluminum wire passes from the top of the left guide wheel 8, then passes from the bottom of the tensioning wheel 4, and then passes from the top of the right guide wheel 8, and then passes from the right side of the rotary wheel 2. The effect of such arrangement is that the first spring 6 is always in a stressed state. During the drawing operation, when the tensioning force of the aluminum wire is small, a part of the elastic force of the first spring 6 is released, thereby driving the sliding seat 3 and the tensioning wheel 4 to move downward. When the tensioning force of the aluminum wire is too large, the tensioning wheel 4 will be pulled upward, thereby further accumulating force on the first spring 6, so that the tensioning wheel 4 is always in close contact with the aluminum wire to provide the tensioning force required for the aluminum wire, so that the aluminum wire is always kept in a taut state.

[0039] Preferably, the broken wire protection component mechanism includes a guide frame 9, a placement slot 10 is opened on the guide frame 9, a pressure plate 11 is slidably arranged on the vertical plate 1, and the placement slot 10 is located on the movement stroke of the pressure plate 11; and also includes a first power component for driving the pressure plate 11 to move back and forth. Specifically, the guide frame 9 is in the shape of an elongated strip, and the guide frame 9 is arranged between the guide wheel 8 and the tensioning wheel 4, and its cross section is preferably L-shaped. The placement groove 10 is a hollow area between the guide frame 9 and the surface of the protrusion 7, and the aluminum wire is located in the placement groove 10. The surface of the protrusion 7 is provided with an inclined groove 12, and the pressure plate 11 is slidably connected with the inclined groove 12. The end of the pressure plate 11 is an arc-shaped surface, and the thickness of the pressure plate 11 outside the inclined groove 12 is less than the width of the placement groove 10. The first power component can be an existing reciprocating drive component such as an electric push rod. The purpose of such a setting is that when the aluminum wire breaks, the first power component controls the pressure plate 11 to move toward the placement groove 10. When the pressure plate 11 abuts against the aluminum wire inside the placement groove 10, the aluminum wire can be fixed in the guide frame 9, so that the aluminum wire cannot continue to move. When the aluminum wire needs to be taken out of the placement groove 10, the pressure plate 11 is controlled to move in the opposite direction by the first power component to release its restrictive effect on the aluminum wire.

[0040] Furthermore, a roller 13 is rotatably arranged on the guide frame 9. Specifically, there are four rollers 13, and the four rollers 13 are respectively arranged at the two ends of the two guide frames 9. The purpose of such arrangement is that when the tensioning force provided by the tensioning wheel 4 makes the aluminum wire close to the inner wall of the placement groove 10, the aluminum wire will contact the roller 13 to drive the roller 13 to rotate, thereby converting the sliding friction between the aluminum wire and the placement groove 10 into rolling friction, so as to minimize the wear of the aluminum wire, thereby reducing the risk of aluminum wire breakage.

[0041] As an alternative solution for the above-mentioned electric push rod to control the reciprocating movement of the pressing plate 11, the first power assembly includes a connecting frame 14 fixedly connected to the sliding seat 3, and a connecting rod 15 is rotatably arranged between the connecting frame 14 and the pressing plate 11. Specifically, the connecting frame 14 is fixedly connected to the upper surface of the sliding seat 3, which is approximately a T-shaped structure, and fixed shafts are arranged at both ends of its horizontal section edge. A fixed shaft is also arranged on one end of the pressure plate 11 close to the connecting frame 14. There are two connecting rods 15, and the two ends of the connecting rod 15 are rotatably connected to the connecting frame 14 and the fixed shafts on the pressure plate 11 respectively. The effect of such a setting is that when the aluminum wire breaks, its force on the tensioning wheel 4 disappears. At this time, the elastic force of the first spring 6 is released, which will drive the sliding seat 3 and the tensioning wheel 4 to move downward, thereby driving the connecting frame 14 to move downward synchronously. The connecting frame 14 will provide a downward force for the connecting rod 15, thereby pushing the pressure plate 11 to slide toward the inside of the placement groove 10, so that the end of the pressure plate 11 abuts against the aluminum wire. In this process, the first spring 6 has two advantages. First, it provides tensioning force during the drawing process of the aluminum wire. Second, when the elastic force of the first spring 6 is released, it drives the pressure plate 11 to abut against the aluminum wire to achieve passive fixation of the aluminum wire.

[0042] Preferably, the connecting member comprises a mounting ring 16, a connecting column 17 is arranged on the mounting ring 16, and connecting holes 18 adapted to the connecting column 17 are respectively provided on the inner disk 201 and the outer ring 202, and the connecting column 17 is plugged into the connecting hole 18. Specifically, the mounting ring 16 is arranged below the rotary wheel 2, a convex ring is arranged on the outer edge of the inner disk 201, and a convex ring is also arranged on the inner edge of the outer ring 202, and the convex ring parts of the two are superimposed together, and the connecting hole 18 is arranged in the convex ring part. When the connecting column 17 is inserted into the connecting holes 18 on the inner disk 201 and the outer ring 202 at the same time, a limiting effect is generated on the circumferential direction of the two, so that the inner disk 201 and the outer ring 202 cannot rotate. At this time, the inner disk 201 can drive the outer ring 202 to rotate synchronously while rotating.

[0043] Furthermore, a movable groove 19 is provided on the vertical plate 1, and a slide bar 20 is provided on the mounting ring 16. The slide bar 20 is slidably connected with the movable groove 19. An avoidance groove 21 is provided on the inner wall of the movable groove 19, and a pad 22 is slidably provided in the avoidance groove 21; and a second power assembly for driving the pad 22 to reciprocate is also included. Specifically, the movable groove 19 is provided inside the protruding portion 7, and the mounting ring 16 includes an inner ring 1601 and an outer ring 1602. The inner ring 1601 and the outer ring 1602 are rotatably connected, and a limiting structure for preventing the two from detaching from each other is provided between the two. The slide bar 20 is fixedly connected to the outer peripheral surface of the outer ring 1602, which is inserted into the movable groove 19, and a limiting structure for preventing the slide bar 20 from moving along the length direction of the movable groove 19 is provided between the slide bar 20 and the movable groove 19. The connecting column 17 is fixedly connected to the upper surface of the outer ring 1602, and the pad 22 is positioned at the bottom of the movable groove 19. The movable groove 19 is located below the slide bar 20, and the vertical height of the movable groove 19 is approximately equal to the sum of the vertical heights of the slide bar 20 and the cushion block 22. The second power assembly can also be an existing reciprocating drive assembly such as an electric push rod. The effect of such a setting is that during the normal drawing process of the aluminum wire, the slide bar 20 fits the inner top wall of the movable groove 19. At this time, the connecting column 17 is inserted into the connecting holes 18 on the inner disk 201 and the outer ring 202 at the same time, so that the inner ring 1601 can rotate with the rotary wheel 2, and at this time the cushion block 22 is located below the slide bar 20, so that the slide bar 20 cannot move downward. When the aluminum wire breaks, the connecting frame 14 moves downward to drive the pressure plate 11 to move toward the direction of the aluminum wire. The second power assembly drives the cushion block 22 to slide toward the inside of the avoidance groove 21. When the cushion block 22 completely enters the inside of the avoidance groove 21, its limiting effect on the vertical direction of the slide bar 20 disappears. At this time, the slide bar 20, the mounting ring 16 and the connecting column 17 move downward under the action of gravity, so that the connecting column 17 is pulled out of the connecting hole 18. At this time, the power of the inner plate 201 It will not be transmitted to the outer ring 202, thus realizing the passive disconnection of the inner disk 201 and the outer ring 202. After the aluminum wire is removed, align the connecting holes 18 on the inner disk 201 and the outer ring 202, then lift the slide bar 20 upward, and then insert the connecting column 17 into the connecting holes 18 on the inner disk 201 and the outer ring 202 at the same time to complete the resetting of the connecting column 17. At this time, the cushion block 22 is controlled to move in the opposite direction by the second power component, so that the cushion block 22 is inserted between the slide bar 20 and the inner bottom wall of the movable groove 19 to realize the resetting of the cushion block 22.

[0044] As an alternative to the above-mentioned electric push rod driving the cushion block 22 to move back and forth, the second power assembly includes a transmission rod 24 fixedly connected to the pressure plate 11, and the transmission rod 24 abuts against the cushion block 22; and a second spring 23 is provided between the cushion block 22 and the avoidance groove 21. Specifically, the transmission rod 24 is fixedly connected to one of the pressure plates 11, and its end is hemispherical, and the end of the transmission rod 24 abuts against the side of the cushion block 22, one end of the second spring 23 is fixedly connected to the cushion block 22, and the other end is fixedly connected to the side wall of the avoidance groove 21, and the second spring 23 is in a stretched state. The effect of such a setting is that when the aluminum wire breaks, the connecting frame 14 drives the pressure plate 11 to slide along the inclined groove 12, which will drive the transmission rod 24 to move synchronously. When the end of the transmission rod 24 moves away from the side of the cushion block 22, Under the action of the second spring 23, the cushion block 22 is pulled toward the inside of the avoidance groove 21. When the cushion block 22 is away from the slide bar 20, the limiting effect of the slide bar 20 is passively released, so that the slide bar 20 can move downward. In summary, the tensioning assembly has the following functions: first, maintaining the tensioning force of the aluminum wire; second, driving the pressure plate 11 to abut against the aluminum wire to passively fix the aluminum wire; and third, driving the connecting column 17 to be pulled out of the connecting hole 18 to separate the inner disk 201 from the outer ring 202.

[0045] Preferably, the surfaces of the inner disk 201 and the outer disk that are in contact with each other are made of frosted metal material. When the aluminum wire breaks, the inner disk 201 and the outer ring 202 will rotate relative to each other, and friction will be generated between the frosted metals to emit a piercing alarm sound. This is a prior art and will not be elaborated on. The alarm sound is used to remind the staff that the aluminum wire has broken and needs to be stopped for processing.

[0046] In order to facilitate the resetting of the cushion block 22 , preferably, the cushion block 22 is provided with a wedge-shaped surface. Specifically, the wedge-shaped surface is arranged on the surface of the pad 22 close to the transmission rod 24. The purpose of such arrangement is that during the normal pulling process of the aluminum wire, the transmission rod 24 abuts against the vertical surface of the pad 22. When the aluminum wire breaks, the connecting frame 14 will move downward, thereby driving the transmission rod 24 to move obliquely downward. During the oblique downward movement of the transmission rod 24, the transmission rod 24 and the vertical surface of the pad 22 will be separated. At this time, the elastic force of the second spring 23 is gradually released, which will cause the transmission rod 24 to slide downward along the wedge-shaped surface of the pad 22 to achieve avoidance. When the broken aluminum wire is removed, the sliding rod 20 is lifted upward, and the connecting column 17 is inserted into the connecting hole 18, and then the sliding seat 3 is lifted upward, so that the transmission rod 24 abuts against the wedge-shaped surface of the pad 22, so that the pad 22 slides passively toward the outside of the avoidance groove 21, thereby fixing the position of the sliding rod 20 again, so that the pad 22 is driven to be passively reset during the resetting of the tensioning wheel 4.

[0047] It should be noted that when the device is idle, the position of the reset tensioning wheel 4 can be fixed by bolts. During this process, the first spring 6 is force-accumulated, so that the positions of structures such as the cushion block 22 and the slide rod 20 can be synchronously fixed, thereby preventing the inner disk 201 and the outer ring 202 from rotating relative to each other. When the aluminum wire is wound, the limiting effect of the tensioning wheel 4 is released, the elastic force of the first spring 6 is released, and it abuts against the aluminum wire to facilitate the winding of the aluminum wire.

[0048] Furthermore, the inner disk 201 and the outer ring 202 are respectively provided with indicator marks 25. Specifically, the indicator marks 25 are preferably arrows, which are provided on the upper surfaces of the inner disk 201 and the outer ring 202. When the arrows on the inner disk 201 and the outer ring 202 are opposite to each other, that is, the connecting holes 18 inside the two overlap, at this time, the connecting column 17 can be inserted into the connecting holes 18 inside the inner disk 201 and the outer ring 202 at the same time, so as to facilitate the resetting of the connecting column 17.

[0049] As another embodiment of the present invention, a baffle 26 is rotatably provided on the outer ring 202, a blocking rod 27 is elastically provided on the outer ring 202, a limiting portion 28 is provided on the baffle 26, and the blocking rod 27 abuts against the limiting portion 28, a first abutting rod 29 is fixedly connected to the inner disk 201, a second abutting rod 30 is slidably provided on the blocking rod 27, a limiting groove 31 is provided on the outer ring 202, a limiting rod 32 is fixedly connected to the blocking rod 27, the limiting rod 32 is slidably connected to the limiting groove 31, and the second abutting rod 30 is located on the rotation stroke of the first abutting rod 29. Specifically, the baffle 26 is preferably an arc-shaped plate, and the baffle 26 includes a body 2601 and a connecting portion 2602. A rotating seat is fixedly connected to the outer ring 202, and a torsion spring (not shown) is arranged between the connecting portion 2602 and the rotating seat. The elastic force of the torsion spring makes the baffle 26 have a tendency to swing downward, and the limiting portion 28 is arranged on the connecting portion 2602. The blocking rod 27 includes a first horizontal section 2701, a second horizontal section 2702 and a vertical section 2703. The limiting portion 28 is a groove structure opened on the connecting portion 2602, and the end of the first horizontal section 2701 abuts against the inner wall of the groove, and the end of the second horizontal section 2702 abuts against the inner wall of the groove. There is a gap between the horizontal section 2702 and the connecting portion 2602, a transverse groove 33 is provided on the upper surface of the outer ring 202, and a third spring 34 is provided between the elastic arrangement, that is, the vertical section 2703 and the transverse groove 33, and the third spring 34 is in a compressed state, the second abutting rod 30 is arranged through the vertical section 2703, the limiting rod 32 is located at the end of the second abutting rod 30 away from the inner disk 201, and the limiting groove 31 includes a transverse section 3101 and an inclined section 3102, and the inclined section 3102 is arranged in an inclined direction away from the inner disk 201. The function of such an arrangement is that when the aluminum wire is broken, After the crack, there will be relative rotation between the inner disk 201 and the outer ring 202, and because the second abutting rod 30 is located on the movement stroke of the first abutting rod 29, the first abutting rod 29 will abut against the second abutting rod 30 during the rotation, thereby driving the second abutting rod 30 and the limiting rod 32 to slide along the transverse section 3101 of the limiting groove 31, thereby driving the blocking rod 27 to slide along the transverse groove 33 through the second abutting rod 30, and accumulating force on the third spring 34, so that the first horizontal section 2701 is pulled out of the limiting portion 28, and the elastic force of the torsion spring is released at this time, which drives the baffle 26 to move. The first horizontal section 2701 is rotated downward to cover the annular groove on the rotating wheel 2, thereby preventing the aluminum wire from falling off the rotating wheel 2, thereby further preventing the aluminum wire from being entangled on the rotating shaft. During the subsequent rotation of the first abutting rod 29, the first abutting rod 29 and the second abutting rod 30 will be separated. At this time, the elastic force of the third spring 34 is released, thereby driving the blocking rod 27 to move in the reverse direction. At this time, the first horizontal section 2701 lacks the blocking effect of the limiting portion 28, so that the elastic force of the third spring 34 can be further released, thereby driving the blocking rod 27 to slide in the reverse direction for a greater distance. In this process, it has the following stroke:First, after the baffle 26 rotates downward to cover the annular groove of the rotating wheel 2, the connecting portion 2602 will rotate from the vertical state to the horizontal state. Therefore, the first horizontal section 2701 will move to the upper side of the connecting portion 2602, thereby limiting the connecting portion 2602, so that the baffle 26 cannot rotate in the reverse direction, so as to stably limit the baffle 26 in this state. Second, the further movement of the blocking rod 27 will cause the transverse section 3101 of the limiting rod 32 to enter the inclined section 3102. Since the inclined section 3102 is arranged in a direction away from the inner disk 201, it will drive the second abutting rod 30 to move away from the inner disk 201. 01, so that the second abutment rod 30 is no longer located in the movement stroke of the first abutment rod 29. In the subsequent rotation process of the inner disk 201, the first abutment rod 29 can be prevented from abutting against the second abutment rod 30 multiple times, reducing the resistance to the rotation of the inner disk 201. After the abnormality of the aluminum wire breakage is handled, the blocking rod 27 is pulled in the reverse direction while the baffle 26 is rotated in the reverse direction. When the connecting portion 2602 is rotated to a vertical state, the blocking rod 27 is released and moves in the reverse direction under the action of the third spring 34, so that the first horizontal section 2701 abuts against the limiting portion 28 again, so as to realize the reset of the baffle 26 and the blocking rod 27.
