Description

Technical Field

[0001] The invention relates to the technical field of wire drawing, and in particular to a stainless steel wire drawing die. Background Art

[0002] The wire drawing die includes a die sleeve and a die core. It refers to a tool that forces metal to pass through the die under the action of external force during metal pressure processing, compresses the metal cross-sectional area, and obtains the required cross-sectional area shape and size. When processing stainless steel wire, it is necessary to use a wire drawing die for wire drawing processing and forming. However, there are usually the following problems during the processing:

[0003] First of all, in the process of metal extrusion through the die, impurities and lubricant residues on the surface of the stainless steel wire will gradually accumulate in the drawing holes of the die, affecting the drawing quality and die life, so the die needs to be replaced regularly.

[0004] Secondly, the wear of the mold should be monitored regularly, and the degree of mold wear should be timely understood by measuring the size change of the drawing hole and observing the wear marks on the mold surface. When the mold wear reaches a certain limit, it should be replaced or repaired in time. However, in actual operation, it is usually very difficult to detect the stainless steel wire being drawn. It is only after the drawing is completed that the drawing hole is found to be worn during the drawing process and the subsequent use is affected.

[0005] For this purpose, we designed a stainless steel wire drawing die. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that it is usually extremely difficult to detect the stainless steel wire being drawn in actual operation, and only after the wire drawing is completed can the wear of the drawing hole in the wire drawing process be found. A stainless steel wire drawing die is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A stainless steel wire drawing die, comprising a wire drawing box body and a first rotating shaft arranged below the wire drawing box body. A stainless steel wire passes through the wire drawing box body. A wire supporting frame and a rubber clamping ring for stabilizing the stainless steel wire are arranged in the wire drawing box body. A plurality of wire drawing dies are arranged circumferentially on the first rotating shaft. The stainless steel wire passes through one of the wire drawing dies. The wire supporting frame and the rubber clamping ring are respectively arranged on both sides of the wire drawing die. A detection collar for detecting the diameter size of the stainless steel wire is arranged between the wire drawing die and the wire supporting frame. On the other side of the wire supporting frame, there is a cutting knife assembly connected to the detection collar and coaxially sleeved with the stainless steel wire. The rubber clamping ring slides in the wire drawing box body through a sliding bracket, and a magnet block is fixed on the sliding bracket. An electromagnetic generator for pushing the magnet block away is further arranged on the wire drawing box body.

[0009] Preferably, the first rotating shaft rotates at the bottom of the wire drawing box body through a shaft bracket, and a rotating frame is fixed on the outer side wall of the first rotating shaft. A plurality of wire drawing dies are fixedly arranged circumferentially on the rotating frame. A side hole is formed in the side wall of the wire drawing box body, and the rotating frame drives the plurality of wire drawing dies to cross over the side hole.

[0010] Preferably, a slide rail is arranged on the top of the wire drawing box body, and the wire supporting frame is fixed on the slide rail. The sliding bracket slides on the slide rail through the magnet block. A first return spring is connected between the electromagnetic generator and the magnet block.

[0011] Preferably, a first inner cavity and a second inner cavity are circumferentially formed in the detection collar, and the first inner cavity and the second inner cavity are separated by a baffle. A roller bracket slides in the first inner cavity, and a rotating wheel that abuts against the outer side wall of the stainless steel wire is rotatably arranged on the roller bracket. A second return spring is arranged between the baffle and the roller bracket.

[0012] Preferably, the roller bracket includes a top frame and two side wall frames. The rotating wheel is arranged between the two side wall frames and rotates. The rotating wheel is connected to the bottom of the top frame. A swinging hole is formed through the top frame, and a rotating part is rotatably arranged in the swinging hole. The rotating part is connected to the rotating wheel.

[0013] Preferably, a lifting plate slides up and down in the second inner cavity. A positioning plate for preventing the lifting plate from descending is fixed in the second inner cavity. A pressing rod penetrating through the baffle is fixed to the bottom of the lifting plate, and the pressing rod pushes against the lifting plate to lift it.

[0014] Preferably, the rotating part includes a combination of a semi-circular block and a triangular block. The rotating part rotates in the swinging hole through a second rotating shaft. A third inner cavity is provided on the rotating part, and a reset spring is coaxially sleeved in the third inner cavity. One end of the reset spring is fixed to the third inner cavity, and the other end is fixed to the side wall of the swinging hole. A positioning block for limiting the rotation of the rotating part is fixed on the inner wall of the swinging hole.

[0015] Preferably, the end of the triangular block of the rotating part is provided with a flat top end, and the flat top end of the rotating part in the vertical state is flush with the top frame.

[0016] Preferably, an oil cavity is provided on the detection collar. The oil cavity is semi-circular arc-shaped, and communication holes communicating with the second inner cavity are provided at both ends of the oil cavity.

[0018] The beneficial effects of the present invention are as follows:

[0019] The tremor of the stainless steel wire in the present invention will drive the continuous swinging of the stainless steel wire, but the diameter of the stainless steel wire will not change. Referring to Figure 4 the state, when the stainless steel wire trembles and presses towards the rotating wheel 16A, it can also drive the rotating wheel 16A to continue rotating. However, at this time, the stainless steel wire will break away from the symmetrical rotating wheel 16B, and then the rotating wheel 16B will no longer rotate, and at the same time, it will not let the stainless steel wire press the rotating wheel 16B. That is, in the tremor state, the rotating wheel 16A is squeezed and rotates, while the rotating wheel 16B is not squeezed and does not rotate. When the wire drawing die is damaged, the diameter of the drawn stainless steel wire increases, which will evenly squeeze the rotating wheel 16A and the rotating wheel 16B and drive both the rotating wheel 16A and the rotating wheel 16B to rotate.

[0020] An installation cavity is further provided in the detection collar of the present invention. The push rod extends into the installation cavity, and a communication circuit device is provided in the installation cavity. The communication circuit device is a parallel circuit. Two opposite rotating wheels form a parallel switch trigger part and connect the communication circuit device in the installation cavity. Thus, if one of the opposite rotating wheels is jointly squeezed and rotated, the opening of the communication circuit device will be triggered. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Refer to Figures 1-10A stainless steel wire drawing die comprises a wire drawing box body 1 and a first rotating shaft 3 arranged below the wire drawing box body 1, a stainless steel wire 6 is passed through the wire drawing box body 1, the first rotating shaft 3 rotates at the bottom of the wire drawing box body 1 through an axis bracket, and a rotating frame 4 is fixed to the outer side wall of the first rotating shaft 3, and a plurality of wire drawing dies 5 are fixed on the rotating frame 4 in a circular shape, wherein the wire drawing dies 5 and the rotating frame 4 are in a detachable state, that is, when the wire drawing dies 5 are damaged, they are disassembled and replaced.

[0033] A side hole 2 is provided on the side wall of the wire drawing box body 1, and the rotating frame 4 drives multiple wire drawing dies 5 to pass through the side hole 2. Multiple wire drawing dies 5 are circumferentially arranged on the first rotating shaft 3, and the stainless steel wire 6 passes through one of the wire drawing dies 5. Then, when the stainless steel wire 6 is cut off, the first rotating shaft 3 is driven by the external driving mechanism to rotate, driving the original wire drawing die 5 to detach and switch to the next new wire drawing die 5, thereby completing the rapid replacement of the damaged wire drawing die 5.

[0034] A wire supporting frame 7 and a rubber clamping ring 13 are provided in the wire drawing box body 1 to assist in stabilizing the stainless steel wire 6. The wire supporting frame 7 and the rubber clamping ring 13 are respectively arranged on both sides of the wire drawing die 5, wherein the wire supporting frame 7 is used to support the stainless steel wire 6 between the wire drawing die 5 and the cutting knife assembly 10 for stability, and the rubber clamping ring 13 on the other side of the wire drawing die 5 is sleeved on the stainless steel wire 6. It should be noted that a telescopic rubber device is provided in the rubber clamping ring 13, and the telescopic rubber device is used to clamp the outer wall of the stainless steel wire 6, that is, when the stainless steel wire 6 is cut off, the telescopic rubber device is opened, and when the rubber clamping ring 13 is inserted into a new wire drawing die 5 with the stainless steel wire 6, the telescopic rubber device will release the clamping of the outer wall of the stainless steel wire 6. The device is a prior art and only plays a pulling and traction effect on the cut stainless steel wire 6, which will not be elaborated here.

[0035] Reference Figure 4 and Figure 9 In this state, a detection ring 11 for detecting the diameter size of the stainless steel wire 6 is provided between the wire drawing die 5 and the wire supporting frame 7, and a first inner cavity 17 and a second inner cavity 18 are circumferentially opened in the detection ring 11, and the first inner cavity 17 and the second inner cavity 18 are blocked by a baffle 19, and a lifting plate 20 is provided in the second inner cavity 18 for lifting and sliding, and a positioning plate 25 for preventing the lifting plate 20 from descending is fixed in the second inner cavity 18, and a pressing rod 21 penetrating the baffle 19 is fixed at the bottom of the lifting plate 20, and the pressing rod 21 pushes the lifting plate 20 to lift it. It should be noted that the lifting of the positioning plate 25 is lifted by the lifting of the rotating part 23.

[0036] A roller support 24 slides within a first inner cavity 17, and a rotating wheel 16 that abuts against the outer sidewall of the stainless steel wire 6 rotates on the roller support 24. It should be noted that during the process of the stainless steel wire 6 passing through the detection collar 11, the rotating wheel 16 can timely feedback the state of the surface of the stainless steel wire 6 to the detection collar 11;

[0037] Among them, during the movement of the stainless steel wire 6, continuous tremors will occur, which will continuously strike the rotating wheel 16 in the corresponding detection collar 11. For conventional detection means, such as diameter detection, monitoring errors will occur due to this part of the tremors, resulting in misjudgment. Therefore, this technical solution is used to eliminate the errors caused by the tremors of the stainless steel wire 6.

[0038] First, due to the tremors of the stainless steel wire 6, it will drive the continuous swinging of the stainless steel wire 6, but the diameter of the stainless steel wire 6 will not change. Refer to Figure 4 the state. When the stainless steel wire 6 trembles and squeezes towards the rotating wheel 16A, it can also drive the rotating wheel 16A to continue rotating. However, at this time, the stainless steel wire 6 will disengage from the symmetrical rotating wheel 16B, and then the rotating wheel 16B will no longer rotate, and at the same time, it will not allow the stainless steel wire 6 to press the rotating wheel 16B;

[0039] That is, in the tremor state, the rotating wheel 16A is squeezed and rotates, while the rotating wheel 16B is not squeezed and does not rotate;

[0040] When the wire drawing die 5 is damaged, the diameter of the stainless steel wire 6 being drawn increases, which will evenly squeeze the rotating wheel 16A and the rotating wheel 16B and drive both the rotating wheel 16A and the rotating wheel 16B to rotate.

[0041] Based on the above two state changes, this technical solution makes the following responses:

[0042] The roller support 24 includes a top frame and two side wall frames. The rotating wheel 16 is arranged between the two side wall frames and rotates. The rotating wheel 16 is connected to the bottom of the top frame. A through swinging hole 33 is opened on the top frame, and a rotating part 23 rotates within the swinging hole 33. The rotating part 23 is connected to the rotating wheel 16. Therefore, when the rotating wheel 16 rotates, it will also drive the rotating part 23 to rotate.

[0043] Refer to Figure 9 and Figure 10State, the rotating part 23 includes a combination of a semi-circular block and a triangular block. The rotating part 23 rotates in the swinging hole 33 through the second rotating shaft 35. A third inner cavity 34 is provided on the rotating part 23, and a reset spring 36 is coaxially sleeved in the third inner cavity 34. One end of the reset spring 36 is fixed to the third inner cavity 34, and the other end is fixed to the side wall of the swinging hole 33. A positioning block 38 for limiting the rotation of the rotating part 23 is fixed on the inner wall of the swinging hole 33. It should be noted that when the rotating wheel 16 rotates, it will drive the rotating part 23 to rotate by relying on friction. Therefore, the rotating part 23 will be in an upright state. Since the end of the triangular block of the rotating part 23 is provided with a top flat end 37, and the top flat end 37 of the vertically standing rotating part 23 is flush with the top frame, this will provide bottom support for the pressing rod 21;

[0044] When the rotating wheel 16 does not rotate, the rotating part 23 is reset under the action of the reset spring 36 and will change from Figure 9 to Figure 10 state, and thus will also lose the support for the pressing rod 21.

[0045] From Figure 9 and Figure 10 states, it can be seen that when the rotating wheel 16 is subjected to rolling extrusion, when the rotating part 23 is in the Figure 9 state, at this time, when the rotating wheel 16 squeezes and lifts the roller bracket 24, it will push and lift the lifting plate 20 with the pressing rod 21; conversely, when the rotating wheel 16 is not subjected to rolling extrusion, when the rotating part 23 is in the Figure 10 state, at this time, when the rotating wheel 16 does not squeeze and lift the roller bracket 24, it will not push and lift the lifting plate 20 with the pressing rod 21, and at the same time, the lifting plate 20 is in a free state at this time, that is, in a non-support state.

[0046] A second reset spring 22 is provided between the baffle 19 and the roller bracket 24. When the rotating wheel 16 on the roller bracket 24 is squeezed, it will be reset under the action of the second reset spring 22.

[0047] An oil cavity 26 is formed in the detection collar 11. The oil cavity 26 is semi-circular, and communication holes 31 communicating with the second inner cavity 18 are formed at both ends of the oil cavity 26. A sliding hole 27 communicating with the oil cavity 26 is formed in the oil cavity 26. A piston 29 slides in the sliding hole 27. A resisting rod 28 is provided on the piston 29. The piston 29 is reset and telescoped in the sliding hole 27 by a third return spring 30. It should be noted that the setting of the oil cavity 26 can ensure that the two ends on both sides are exactly located in the two opposite second inner cavities 18, that is, exactly make the two opposite second inner cavities 18 communicate with each other. That is, when tremors occur, it will drive the stainless steel wire 6 to squeeze one side of the rotating wheel 16, which will drive the oil in the second inner cavity 18 to be squeezed into the communication hole 31 by the lifting plate 20 and flow into the oil cavity 26. Due to the existence of the third return spring 30, the oil will not push the piston 29, but will enter the second inner cavity 18 on the other side. Since the lifting plate 20 at the symmetric position is not supported in the second inner cavity 18, it will push the lifting plate 20 at this position to descend, and thus will not push the piston 29.

[0048] On the contrary, when the diameter of the stainless steel wire 6 becomes larger, the rotating parts 23 that lift the lifting plates 20 on both symmetric sides at the same time will be resisted, and will be lifted as the rotating wheel 16 is lifted, and together push the piston 29 and the positioning block 38 at the end to extend into the installation cavity 32.

[0049] An installation cavity 32 is also provided in the detection collar 11. The resisting rod 28 extends into the installation cavity 32. A connected circuit device is provided in the installation cavity 32. The connected circuit device is a parallel circuit. Two opposite rotating wheels 16 form a parallel switch triggering part and connect the connected circuit device in the installation cavity 32. Thus, if one of the opposite rotating wheels 16 is jointly squeezed and rotated, the connected circuit device will be triggered to be turned on. The connected circuit device is a prior art and will not be elaborated here.

[0050] On the other side of the wire support 7, a cutting knife assembly 10 connected to the detection collar 11 and coaxially sleeved with the stainless steel wire 6 is provided. The rubber clamping ring 13 slides in the wire drawing box body 1 through a sliding bracket 12, and a magnet block 14 is fixed on the sliding bracket 12. An electromagnetic generator 9 for pushing the magnet block 14 away is also provided on the wire drawing box body 1. The connected circuit device is connected to the cutting knife assembly 10 and the electromagnetic generator 9. When the circuit is connected, the cutting knife assembly 10 and the electromagnetic generator 9 will be triggered to be turned on, and the cutting knife assembly 10 will complete the cutting of the stainless steel wire 6.

[0051] A slide rail 8 is provided at the top of the wire drawing box body 1, and the wire support frame 7 is fixed on the slide rail 8. The sliding bracket 12 slides on the slide rail 8 through the magnet block 14. A first return spring 15 is connected between the electromagnetic generator 9 and the magnet block 14. When the stainless steel wire 6 is cut off, the electromagnetic generator 9 will be triggered to start at the same time, generating a magnetic field identical to the opposite end of the magnet block 14, thereby clamping and detaching the rubber clamping ring 13 from the damaged wire drawing die 5. Then, a new wire drawing die 5 is replaced in the wire drawing box body 1, and the cut stainless steel wire 6 is reinserted into the wire drawing die 5 to continue wire drawing the stainless steel wire 6.

[0052] The working principle of the present invention is as follows:

[0053] The first rotating shaft 3 rotates at the bottom of the wire drawing box body 1 through the shaft support, and a rotating frame 4 is fixed on the outer side wall of the first rotating shaft 3. A plurality of wire drawing dies 5 are fixed in a circle on the rotating frame 4. The wire drawing die 5 and the rotating frame 4 are in a detachable state, that is, when the wire drawing die 5 is damaged, it is disassembled and replaced. The stainless steel wire 6 passes through one of the wire drawing dies 5. Then, when the stainless steel wire 6 is cut off, the peripheral drive mechanism drives the first rotating shaft 3 to rotate, driving the original wire drawing die 5 to disengage and switch to the next new wire drawing die 5, completing the rapid replacement of the damaged wire drawing die 5.

[0054] When the rotating wheel 16 rotates, it drives the rotating part 23 to rotate by relying on friction, so that the rotating part 23 is in an upright state. Since the triangular block end of the rotating part 23 is provided with a top flat end 37, and the top flat end 37 of the vertically state rotating part 23 is flush with the top frame, this will provide bottom support for the pressing rod 21.

[0055] When the rotating wheel 16 does not rotate, the rotating part 23 is reset under the action of the reset spring 36, and it will Figure 9 become Figure 10 state, and thus also lose the support for the pressing rod 21.

[0056] From Figure 9 and Figure 10 states, it can be seen that when the rotating wheel 16 is subjected to rolling extrusion, when the rotating part 23 is in the Figure 9 state, at this time, when the rotating wheel 16 squeezes and lifts the roller support 24, it will push and lift the lifting plate 20 with the pressing rod 21; conversely, when the rotating wheel 16 is not subjected to rolling extrusion, when the rotating part 23 is in the Figure 10 state, at this time, when the rotating wheel 16 does not squeeze and lift the roller support 24, it will not push and lift the lifting plate 20 with the pressing rod 21, and at the same time, the lifting plate 20 is in a free state at this time, that is, in a non-support state.

[0057] The arrangement of the oil cavity 26 can ensure that the two ends are exactly located in the two opposite second inner cavities 18, that is, exactly make the two opposite second inner cavities 18 communicate with each other. That is, when tremors occur, it will drive the stainless steel wire 6 to squeeze the rotating wheel 16 on one side, which will drive the hydraulic fluid in the second inner cavity 18 to be squeezed into the communication hole 31 by the lifting plate 20 and flow into the oil cavity 26. Due to the existence of the third return spring 30, the hydraulic fluid will not push the piston 29, but will enter the second inner cavity 18 on the other side. Since the lifting plate 20 at the symmetric position in the second inner cavity 18 has no support, it will push the lifting plate 20 at this position to descend, and thus will not push the piston 29;

[0058] The two opposite rotating wheels 16 form a parallel switch trigger part and connect the communication circuit device in the installation cavity 32. Thus, if one of the two opposite rotating wheels 16 is jointly squeezed and rotated, it will trigger the opening of the communication circuit device. When the circuit is connected, it will trigger the opening of the cutting knife assembly 10 and the electromagnetic generator 9, complete the cutting of the stainless steel wire 6 by the cutting knife assembly 10, and trigger the opening of the electromagnetic generator 9. In this way, a magnetic field identical to the opposite end of the magnet block 14 will be generated, and then the rubber clamping ring 13 will be clamped and separated from the damaged wire drawing die 5. Then, a new wire drawing die 5 is replaced in the wire drawing box body 1, and then the cut stainless steel wire 6 is reinserted into the wire drawing die 5, so as to continue wire drawing of the stainless steel wire 6.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
