DETAILED DESCRIPTION

[0020] Reference Figure 1-Figure 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.

[0021] 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.

[0022] 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.

[0023] Reference Figure 4 and Fig. 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 pressing rod 21 to lift. It should be noted that the lifting of the positioning plate 25 is lifted by the lifting of the rotating part 23.

[0024] A roller bracket 24 slides in the first inner cavity 17, and a rotating wheel 16 is rotated on the roller bracket 24 to abut against the outer wall of the stainless steel wire 6. It should be noted that when the stainless steel wire 6 passes through the detection ring 11, the rotating wheel 16 can timely feed back the state of the surface of the stainless steel wire 6 to the detection ring 11; Among them, the stainless steel wire 6 will vibrate continuously during the movement, so it will continuously touch the rotating wheel 16 in the corresponding detection ring 11, and conventional detection methods, such as diameter detection, will cause monitoring errors due to this part of the vibration, and then misjudgment will occur. Therefore, the technical solution is used to eliminate the error caused by the vibration of the stainless steel wire 6.

[0025] First, the vibration of the stainless steel wire 6 will drive the stainless steel wire 6 to swing continuously, but the diameter of the stainless steel wire 6 will not change. Figure 4 In the state, when the stainless steel wire 6 vibrates, it is squeezed toward the rotating wheel 16A, and can also drive the rotating wheel 16A to continue rotating. However, at this time, the stainless steel wire 6 will be separated from the symmetrical rotating wheel 16B, and the rotating wheel 16B will no longer rotate, and the stainless steel wire 6 will not press the rotating wheel 16B. That is, in the vibration 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 5 is damaged, the diameter of the stainless steel wire 6 being drawn increases, which will squeeze the rotating wheel 16A and the rotating wheel 16B, and drive the rotating wheel 16A and the rotating wheel 16B to rotate.

[0026] According to the above two state changes, this technical solution responds as follows: The roller bracket 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 swing hole 33 is provided on the top frame, and a rotating part 23 rotates in the swing hole 33. The rotating part 23 is connected to the rotating wheel 16, so when the rotating wheel 16 rotates, the rotating part 23 will also rotate.

[0027] Reference Fig. 9 and Fig.10The rotating part 23 comprises a combination of a semicircular block and a triangular block. The rotating part 23 rotates in the swing 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 swing hole 33. A positioning block 38 for limiting the rotation of the rotating part 23 is fixed to the inner wall of the swing hole 33. It should be noted that when the rotating wheel 16 rotates, the rotating part 23 will be driven to rotate by friction, so the rotating part 23 will be in an upright state. Since a top flat end 37 is provided at the end of the triangular block of the rotating part 23, and the top flat end 37 of the rotating part 23 in the vertical state is flush with the top frame, this will provide bottom support for the pressing rod 21. When the rotating wheel 16 does not rotate, the rotating part 23 is reset under the action of the reset spring 36. Fig. 9 become Fig.10 state, and the support for the pressing rod 21 will also be lost.

[0028] from Fig. 9 and Fig.10 As can be seen from the state, when the rotating wheel 16 is subjected to rolling extrusion, when the rotating part 23 is Fig. 9 When the rotating wheel 16 is pressed and the roller bracket 24 is lifted, it will push the lifting plate 20 with the pressing rod 21 to lift; on the contrary, when the rotating wheel 16 is not pressed by rolling, the rotating part 23 is Fig.10 When the rotating wheel 16 does not press and lift the roller bracket 24, it will not push the lifting plate 20 with the pressing rod 21 to lift. At the same time, the lifting plate 20 is in a free state, that is, an unsupported state.

[0029] A second return 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 returned to its original position under the action of the second return spring 22 .

[0030] An oil chamber 26 is provided on the detection collar 11. The oil chamber 26 is semi-arc-shaped, and communicating holes 31 communicating with the second inner chamber 18 are provided at both ends of the oil chamber 26. A sliding hole 27 communicating with the oil chamber 26 is provided on the oil chamber 26. A piston 29 slides in the sliding hole 27. A push rod 28 is provided on the piston 29. The piston 29 is reset and retracted in the sliding hole 27 by a third reset spring 30. It should be noted that the setting of the oil chamber 26 can ensure that the ends on both sides are exactly located at the two opposite second inner chambers 18, that is, the two opposite first inner chambers 18 are exactly located at the two opposite second inner chambers 18. The two inner chambers 18 are interconnected, that is, when vibration occurs, the stainless steel wire 6 will be driven to squeeze the rotating wheel 16 on one side, which will drive the oil in the second inner chamber 18 to be squeezed into the connecting hole 31 by the lifting plate 20 and flow into the oil chamber 26. Due to the presence of the third return spring 30, the oil will not push the piston 29, but will enter the second inner chamber 18 on the other side. Since the lifting plate 20 in the second inner chamber 18 at the symmetrical position has no support, the lifting plate 20 at this position will be pushed down, and the piston 29 will not be pushed.

[0031] On the contrary, when the diameter of the stainless steel wire 6 increases, the lifting plates 20 on both sides will be supported by the raised rotating parts 23 at the same time, and will be lifted along with the lifting of the rotating wheel 16, pushing the piston 29 and the positioning block 38 at the end to extend into the installation cavity 32.

[0032] An installation cavity 32 is also provided in the detection ring 11, and the push rod 28 extends into the installation cavity 32. A connecting circuit device is provided in the installation cavity 32, wherein the connecting circuit device is a parallel circuit, and a parallel switch triggering part is formed relative to the two rotating wheels 16, and the connecting circuit device in the installation cavity 32 is connected, so that if one of the relatively rotating wheels 16 is squeezed and rotated together, the opening of the connecting circuit device will be triggered. The connecting circuit device is a prior art and will not be elaborated on here.

[0033] On the other side of the wire support frame 7, there is a cutting knife assembly 10 connected to the detection ring 11 and coaxially sleeved with the stainless steel wire 6. The rubber clamping ring 13 slides in the wire drawing box body 1 through the sliding bracket 12, and a magnet block 14 is fixed on the sliding bracket 12. The wire drawing box body 1 is also provided with an electromagnetic generator 9 for pushing the magnet block 14 away, wherein the connecting circuit device is connected to the cutting knife assembly 10 and the electromagnetic generator 9. When the circuit is connected, the opening of the cutting knife assembly 10 and the electromagnetic generator 9 will be triggered to complete the cutting of the stainless steel wire 6 by the cutting knife assembly 10.

[0034] A slide rail 8 is provided on 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 reset 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 also be triggered to turn on, which will generate the same magnetic field as the opposite end of the magnet block 14, thereby clamping the rubber clamping ring 13 away from the damaged wire drawing die 5, and then replacing the new wire drawing die 5 in the wire drawing box body 1, and then reinserting the cut stainless steel wire 6 into the wire drawing die 5, so as to continue drawing the stainless steel wire 6.

[0035] The working principle of the present invention is as follows: The first rotating shaft 3 rotates at the bottom of the wire drawing box body 1 through the shaft bracket, and a rotating frame 4 is fixed to the outer side wall of the first rotating shaft 3, and multiple wire drawing dies 5 are fixed on the rotating frame 4 in a circumferential manner, 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, 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, so that the original wire drawing die 5 is driven to disengage and switch to the next new wire drawing die 5, thereby completing the rapid replacement of the damaged wire drawing die 5; When the rotating wheel 16 rotates, the rotating part 23 is driven to rotate by the friction force, so 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 rotating part 23 in the vertical state is flush with the top frame, the bottom support is provided for the pressing rod 21. When the rotating wheel 16 does not rotate, the rotating part 23 is reset under the action of the reset spring 36. Fig. 9 become Fig.10 state, and the support for the pressing rod 21 will also be lost.

[0036] from Fig. 9 and Fig.10 As can be seen from the state, when the rotating wheel 16 is subjected to rolling extrusion, when the rotating part 23 is Fig. 9 When the rotating wheel 16 is pressed and the roller bracket 24 is lifted, it will push the lifting plate 20 with the pressing rod 21 to lift; on the contrary, when the rotating wheel 16 is not pressed by rolling, the rotating part 23 is Fig.10 In the state, when the rotating wheel 16 does not squeeze and lift the roller bracket 24, it will not push the lifting plate 20 with the pressing rod 21 to lift. At the same time, the lifting plate 20 is in a free state, that is, an unsupported state; The setting of the oil chamber 26 can ensure that the ends of both sides are exactly located in the two opposite second inner chambers 18, that is, the two opposite second inner chambers 18 are just connected to each other, that is, when vibration occurs, it will drive the stainless steel wire 6 to squeeze the rotating wheel 16 on one side, so that the oil in the second inner chamber 18 will be squeezed into the connecting hole 31 by the lifting plate 20 and flow into the oil chamber 26. Due to the presence of the third return spring 30, the oil will not push the piston 29, but will enter the second inner chamber 18 on the other side. Since the lifting plate 20 in the second inner chamber 18 at the symmetrical position has no support, the lifting plate 20 at this position will be pushed down, and the piston 29 will not be pushed. A parallel switch triggering part is formed relative to the two rotating wheels 16, and the connecting circuit device in the installation cavity 32 is connected, so that if one of the relatively rotating wheels 16 is squeezed and rotated together, the connecting circuit device will be triggered to open. When the circuit is connected, the cutting knife assembly 10 and the electromagnetic generator 9 will be triggered to open, and the cutting knife assembly 10 will cut the stainless steel wire 6, triggering the electromagnetic generator 9 to turn on, which will generate the same magnetic field as the opposite end of the magnet block 14, and then clamp the rubber clamping ring 13 away from the damaged drawing die 5, and then replace the new drawing die 5 in the drawing box body 1, and then reinsert the cut stainless steel wire 6 into the drawing die 5, so as to continue drawing the stainless steel wire 6.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
