[0034] Reference Figure 1-Figure 5 A wire break protection device for a stainless steel wire drawing machine includes a wire break protection structure arranged behind a wire drawing die in the wire drawing machine. The wire drawing machine is a prior art, which includes a main machine, a wire drawing part, a winding part, a lubrication system, an electrical transmission part and an auxiliary part.

[0035] Furthermore, the main machine is the core part of the wire drawing machine, which is usually driven by an electric motor and realizes the drawing of the wire through a series of gear transmission systems.

[0036] The wire drawing section consists of a wire drawing wheel, a die fixing frame, and a die. After the wire passes through the die, it is wound on the wire drawing wheel and passed through the wire drawing die to make the wire from thick to thin, obtaining wires of different wire gauges. In order to protect the wire drawing die from damage and to prevent the wire unfolding problem caused by the wire breaking, the present invention sets a wire break protection structure at the rear of the wire drawing die, wherein the rear refers to the wire routing area subsequent to the wire outlet end of the wire drawing die.

[0037] The winding section provides the traction tension of the wire for the operation of the winding wheel. Under the action of the traction tension, the wire is wound through the drawing wheel.

[0038] The lubrication system is used to reduce friction, extend the service life of the equipment and ensure the smooth progress of the wire drawing process.

[0039] The electrical transmission part includes the drawing motor, the wire taking-up motor and the wire arranging motor, etc., which control the operation of the wire drawing machine.

[0040] Among them, auxiliary parts, such as the swing rod tension frame, positioning wheel, wire dividing wheel, etc., are used to ensure the wire drawing quality and stable equipment operation.

[0041] The innovative part of the present invention lies in the wire break protection structure arranged at the wire outlet end of the wire drawing die, which includes a wire reel assembly 1, an elastic reel 2, a wire clamping assembly 3 and an actuating assembly 4, wherein the wire reel assembly 1 is divided into two groups, and the stainless steel wire 6 coming out of the wire drawing die passes through the wire clamping assembly 3, the first group of wire reel assemblies 1, the elastic reel 2, the second group of wire reel assemblies 1, the wire clamping assembly 3 in sequence and then moves to the winding part in the wire drawing machine.

[0042] Reference Figure 1 and Figure 2 Each group of wire reel assemblies 1 consists of two wire reels, which are in a reel-shaped structure and have an annular wire groove on their outer wall, which is used to constrain the routing of the stainless steel wire 6. In addition, a wire reel shaft is coaxially fixed on one side of the wire reel, and the other ends of the two wire reel shafts in the same group are connected by the same wire reel bracket. The preferred wire reel bracket is a vertical strip structure, wherein the wire reel bracket is arranged on the side wall of the wire drawing machine, wherein the side wall of the wire drawing machine is a shell for installing the wire drawing machine component structure.

[0043] Reference Figure 1 and Figure 2 In some embodiments, the elastic disk 2 is arranged as a group, which is located below the center position of the two wire disk assemblies 1. After passing through the wire drawing die, the stainless steel wire 6 is sequentially wound around one group of wire disk assemblies 1, the elastic disk 2 and the other group of wire disk assemblies 1, so that the stainless steel wire 6 has a V-shaped routing structure.

[0044] Among them, a group of elastic disks 2 is composed of two disk bodies, which have the same structure and external dimensions as the wire disk, and are also provided with an annular wire groove for constraining the routing of the stainless steel wire 6; in addition, the two disk bodies of the elastic disk 2 are also coaxially fixed with an elastic disk shaft, and the other ends of the two elastic disk shafts are fixed with the same elastic disk bracket. The preferred elastic disk bracket is a vertical strip structure, and the elastic disk bracket slides linearly on the side wall of the wire drawing machine. In some embodiments, a vertical linear slide groove corresponding to the elastic disk bracket is provided on the side wall of the wire drawing machine.

[0045] Based on the setting of the elastic disk 2, the present embodiment also discloses an elastic driving structure of the elastic disk 2, which serves as a trigger structure for the stainless steel wire 6 to break, that is, when the stainless steel wire 6 breaks, the elastic disk 2 moves linearly under the drive of the elastic driving structure, thereby causing the wire clamping assembly 3 to work through the actuating assembly 4. The elastic driving structure is an elastic member, which is arranged between the elastic disk 2 and the side wall of the wire drawing machine. Preferably, the elastic member is a reset spring 50.

[0046] Furthermore, based on the setting of the return spring 50, in order to facilitate the installation of the return spring 50 and to easily drive the elastic disk 2, the elastic member also includes a slide 5, which is arranged between the two elastic disk shafts, and the slide 5 is provided with a positioning groove corresponding to the elastic disk shaft, so that the slide 5 and the elastic disk shaft move synchronously; in addition, a slide groove for linear sliding of the slide 5 is provided on the side wall of the wire drawing machine. Preferably, at least one positioning slide column 51 is provided in the slide groove, and the slide 5 slides on the positioning slide column 51, and the return spring 50 is sleeved on the outer wall of the positioning slide column 51, and at the same time, the two ends of the return spring 50 are respectively connected to the slide 5 and the inner wall of the slide groove.

[0047] After the elastic disk 2 is matched with the two sets of wire disk assemblies 1, the stainless steel wire 6 wound outside the elastic disk 2 is located at the top, and because the support of the elastic disk 2 is completely dependent on the reset spring 50, when the overall tension of the stainless steel wire 6 is adjusted, the elastic disk 2 is prevented from moving, and an adjustable limit portion can be set on the top of the slide 5. The limit portion is a limit block 52. By adjusting the vertical position of the limit block to match the maximum upward position of the elastic disk 2 under the preset tension of the stainless steel wire 6, when the slide 5 hits the limit block 52, the slide 5 is blocked from moving upward, and it is inconvenient to maintain the maximum tension of the stainless steel wire 6. In some embodiments, the adjustment and positioning of the limit block 52 can be achieved by screws or screws, but is not limited to the above two methods of adjusting and positioning the limit block 52. Any method that can achieve the adjustment and positioning of the limit block 52 is acceptable.

[0048] Reference Figure 1 and Figure 2 The wire clamping assembly 3 is arranged on the opposite sides of the two wire reel assemblies 1. Specifically, the wire clamping assembly 3 is arranged in two groups, one group of wire clamping assembly 3 is located between the wire drawing die and the wire reel assembly 1, and the other group of wire clamping assembly 3 is located between the winding part and the wire reel assembly 1. When the stainless steel wire 6 breaks, the wire clamping assembly 3 clamps the broken stainless steel wire 6, thereby preventing the stainless steel wire 6 from damaging the wire drawing die and the winding part after uncontrolled movement.

[0049] The wire clamping assembly 3 includes at least two relatively movable wire clamping protrusions and a driving portion of the wire clamping protrusions.

[0050] In this embodiment, the clamping protrusion is an arc block 30 with the outer wall turned outward, and the arc block 30 is provided in plurality. Figure 4 , multiple arc blocks 30 are arranged in a ring shape. In this embodiment, the stainless steel wire 6 passes through the circular hole in the middle of the multiple arc blocks 30. When the multiple arc blocks 30 are driven by the driving part of the wire clamping protrusion, they converge inward, causing the multiple arc blocks 30 to clamp the peripheral wall of the stainless steel wire 6 in a surrounding clamping manner, thereby preventing the movement of the stainless steel wire 6 after the wire is broken. However, the wire clamping protrusion is not limited to the arc block 30 structure with the outer wall turned outward, and can also be a relatively movable block structure.

[0051] In some embodiments, the driving portion of the wire clamping protrusion is composed of an inner tube body 31, an outer tube body 32 and a driving tube 33, and the inner tube body 31 and the outer tube body 32 are coaxially fixed by connecting ribs, and the setting position of the connecting ribs does not affect the sliding of the driving tube 33. In addition, the driving tube 33 slides between the inner tube body 31 and the outer tube body 32, and the arc block 30 is fixed to the outer end of the inner tube body 31. When the driving tube 33 moves toward the arc block 30, the inner wall of the driving tube 33 presses the outer wall of the arc block 30, so that multiple arc blocks 30 converge to clamp one end of the stainless steel wire 6 after the wire is broken.

[0052] Reference Figure 1 and Figure 2 The actuating assembly 4 is arranged between the elastic disk 2 and the wire clamping assembly 3. When the stainless steel wire 6 is broken, the elastic disk 2 senses the pressure change, and under the drive of the return spring 50, the transmission force of the actuating assembly 4 causes the driving tube 33 in the wire clamping assembly 3 to move in advance, thereby preventing the broken stainless steel wire 6 from reaching the wire drawing die, thereby protecting the wire drawing die.

[0053] In some embodiments, the actuation assembly 4 includes a snap-on disk 40 and an actuation disk 41. Figure 1 , Figure 2 and Figure 3 The snap-on disk 40 is a boss structure, and a snap-on disk shaft 400 is eccentrically fixed to one side of its outer wall, and the snap-on disk shaft 400 rotates on the side wall of the wire drawing machine; the actuating disk 41 is a disc structure, and an actuating disk shaft 410 is concentrically fixed to one side of its outer wall, and the actuating disk shaft 410 rotates on the side wall of the wire drawing machine. It should be supplemented that: the snap-on disk 40 and the actuating disk 41 are both connected to the side wall of the wire drawing machine through a torsion spring 45, and the preferred torsion spring 45 is wound around the snap-on disk shaft 400 and the actuating disk shaft 410, and the two ends of the torsion spring 45 are respectively connected to the side wall of the wire drawing machine and the outer wall of the snap-on disk 40 or the actuating disk 41, and the torsion spring 45 is provided to stabilize the snap-on state of the snap-on disk 40 and the actuating disk 41, and at the same time provide power for driving the wire clamping assembly 3.

[0054] Furthermore, the buckling mode of the buckling disk 40 and the actuating disk 41 is preferably a snap-on mode, preferably, the buckling is achieved through an elastic buckling portion 44, and the elastic buckling portion 44 includes a buckling portion 440 and a buckling groove 441. The buckling portion 440 can be stored in the buckling disk 40. Preferably, a receiving groove for storing the buckling portion 440 is provided in the buckling disk 40. In order to ensure that the buckling portion 440 automatically pops out in a natural state, the buckling portion 440 is connected to the inner wall of the receiving groove through a buckling portion spring, wherein the buckling portion 440 is a sickle-shaped structure, and a buckling secondary groove 4400 is formed between it and the outer wall of the buckling disk 40 to enhance the buckling effect, but the buckling portion 440 is not limited to a sickle-shaped structure. In addition, the buckling groove 441 is V-shaped and is provided on the actuating disk 41, and the inner wall of the buckling groove 441 is provided with a buckling secondary groove protrusion 4410 corresponding to the buckling secondary groove 4400.

[0055] Based on the arrangement of the snap-fit ​​portion 440 and the snap-fit ​​groove 441, when the snap-fit ​​portion 440 is located in the snap-fit ​​groove 441, the snap-fit ​​disk 40 and the actuating disk 41 cannot rotate independently, and the snap-fit ​​secondary groove 4400 and the snap-fit ​​secondary groove protrusion 4410 cooperate to strengthen the snap-fit ​​stability of the snap-fit ​​portion 440 and the snap-fit ​​groove 441; on the contrary, when the snap-fit ​​portion 440 and the snap-fit ​​groove 441 are disengaged, under the action of the torsion spring 45, the snap-fit ​​disk 40 and the actuating disk 41 are both Figure 2 Rotate clockwise.

[0056] The elastic snap-fitting portion 44 is connected to the elastic member through the pull wire 42. Specifically, the connection positions at both ends of the pull wire 42 are the outer wall of the slide 5 and the snap-fitting portion 440, respectively. Through the connection of the pull wire 42, when the elastic disk 2 senses that the stainless steel wire 6 is broken, the slide 5 moves downward, pulling the pull wire 42, causing the snap-fitting portion 440 to be received in the snap-fitting disk 40, and then disengaged from the snap-fitting groove 441, then the snap-fitting disk 40 and the actuating disk 41 lose the mutual restraining force, and the snap-fitting disk 40 and the actuating disk 41 rotate under the action of the torsion spring 45, thereby driving the wire clamping assembly 3 to clamp the broken stainless steel wire 6.

[0057] In some embodiments, in order to facilitate the routing of the pull wire 42, a restraining disk for restraining the routing of the pull wire 42 is provided on the snap-fit ​​disk shaft 400, and a pull wire connecting seat is also rotatably provided on the snap-fit ​​disk 40, and the other end of the pull wire 42 is tied to the pull wire connecting seat. In addition, the pull wire connecting seat is fixed to the snap-fit ​​portion 440, so that the snap-fit ​​portion 440 rotates with the pull wire connecting seat as the center of rotation. When the pull wire 42 pulls the pull wire connecting seat, the snap-fit ​​portion 440 is received into the receiving groove in a rotational manner.

[0058] In addition, refer to Figure 1 and Figure 2 , wherein the actuating disk 41 and the driving portion of the wire clamping protrusion are connected by a sliding link 43, and further, the driving tube 33 is fixed to the sliding link 43; in addition, an actuating portion 411 is also fixed to one side of the actuating disk 41, and a linear sliding opening 4110 for sliding of the sliding link 43 is provided on the actuating portion 411, wherein the sliding link 43 is in a U-shaped structure, and the horizontal end of the sliding link 43 slides in the linear sliding opening 4110. When the actuating disk 41 rotates, the actuating portion 411 follows the rotation, and then the driving tube 33 is driven to move horizontally through the resistance force of the inner wall of the linear sliding opening 4110 on the sliding link 43, thereby completing the wire clamping process.

[0059] Reference Figure 1 and Figure 2 This embodiment also discloses a wire extension component for delaying the rapid movement of the wire end of the stainless steel wire 6 after the wire is broken. The wire extension component is configured as follows:

[0060] First, a wire drawing roller 7, a wire winding roller 8 and a connecting wall 9 are horizontally slidably mounted on the side wall of the wire drawing machine. The connecting wall 9 is fixed to one end of the wire drawing roller 7 and the wire winding roller 8. The wire winding roller 8 and the wire drawing roller 7 are respectively located at the upper and lower sides of the wire reel assembly 1;

[0061] Secondly, a connecting shaft 401 is also fixed to the outer wall of the buckling disk 40, wherein the wire connecting seat is rotatably sleeved on the outer wall of the connecting shaft 401; in addition, the connecting shaft 401 is connected to the wire guide roller 7 through a connecting rod A402.

[0062] Based on the setting of the wire extension assembly, when the wire is broken, the buckle plate 40 rotates, and the lead roller 7, the winding roller 8 and the connecting wall 9 are driven to move forward synchronously through the connecting rod A402. Figure 1 and Figure 2 , the broken stainless steel wire 6 is under the horizontal thrust of the lead roller 7, so that the outer wall of the lead roller 7 generates an upward force on the broken stainless steel wire 6, so that the stainless steel wire 6 moves upward and is wound on the winding roller 8. When the broken stainless steel wire 6 is wound on the winding roller 8, the recovery speed of the broken stainless steel wire 6 is delayed. At the same time, when the end of the broken stainless steel wire 6 is wound on the winding roller 8, the friction force and winding force on the surface of the winding roller 8 will also offset the recovery force on the broken stainless steel wire 6, thereby further reducing the recovery speed of the broken stainless steel wire 6, providing time for the clamping assembly 3 to clamp the broken stainless steel wire 6, thereby ensuring the clamping effect of the clamping assembly 3 on the broken stainless steel wire 6.

[0063] It should be added that: the connecting wall 9 is a telescopic arm structure or a non-telescopic arm structure. When the connecting wall 9 is a non-telescopic arm structure, the line where the center of the lead roller 7 and the center of the buckle disk shaft 400 are located is in the same horizontal movement direction as the lead roller 7; when the connecting wall 9 is a telescopic arm structure, the setting position of the lead roller 7 is not limited by space, refer to Figure 1 and Figure 2 Specifically, the connecting wall 9 is composed of an upper sleeve wall and a lower embedded wall structure, and the lower embedded wall slides linearly in the upper sleeve wall.

[0064] In order to further enhance the friction force on the surface of the winding roller 8, the winding roller 8 is prismatic and an anti-slip groove 80 is provided on the winding roller 8. Figure 4 The anti-skid groove 80 is an embedded groove, and the anti-skid groove 80 includes a surface groove and a corner groove. The surface groove is arranged along the prismatic surface of the winding roller 8, and the corner groove is arranged at the corner of the winding roller 8, and the corner groove is an eight-shaped structure. In this way, it is ensured as much as possible that the stainless steel wire 6 contacts the surface groove after passing through the corner groove after breaking, thereby further increasing the friction force by increasing the contact area.

[0065] Finally, in order to further increase the number of windings of the stainless steel wire 6 on the winding roller 8 after the wire is broken, thereby further delaying the recovery speed of the stainless steel wire 6 after the wire is broken, refer to Figure 2 A slide rail 90 for horizontal sliding on the side wall of the wire drawing machine is fixed on the connecting wall 9, wherein a slideway for horizontal sliding of the slide rail 90 is arranged on the side wall of the wire drawing machine, wherein the slideway is embedded; in addition, the slide rail 90 is connected to the wire reel assembly 1 through a horizontally arranged connecting rod B91, further, both ends of the connecting rod B91 are rotatably connected to the wire reel bracket and the slide rail 90, and the connecting rod B91 is arranged in a horizontal state and only rotates in the same horizontal plane; secondly, the wire reel assembly 1 can extend into the side wall of the wire drawing machine.

[0066] Based on the setting of the connecting rod B91 and the slide rail 90, when the lead roller 7, the winding roller 8 and the connecting wall 9 extend forward, the connecting rod B91 drives the wire reel assembly 1 to move into the side wall of the wire drawing machine, so that when the stainless steel wire 6 is recovered after the wire is broken, the wire reel assembly 1 moves into the side wall of the wire drawing machine relative to the winding roller 8, so that the position of the stainless steel wire 6 wound on the winding roller 8 after the wire is broken is constantly changed. Specifically, the stainless steel wire 6 is spirally wound on the winding roller 8 after the wire is broken, which not only increases the number of winding turns of the stainless steel wire 6, but also increases the contact area between the stainless steel wire 6 and the winding roller 8 after the wire is broken. Furthermore, in this embodiment, the stainless steel wire 6 is further increased after the wire is broken, and the surface groove of the anti-slip groove 80 is inclined, and the inclination direction is the opposite setting of the movement of the wire reel assembly 1 relative to the winding roller 8.

[0067] It should be noted that: when the connecting wall 9 is Figure 1 and Figure 2 When the telescopic arm structure is used, the slide rail 90 is arranged on the outer wall of the upper sleeve wall of the connecting wall 9.

[0068] The working principle of the present invention is as follows:

[0069] When the stainless steel wire 6 breaks, the elastic disk 2 loses the pulling force of the stainless steel wire 6, and under the action of the return spring, the slide 5 moves downward, and the snap-fitting portion 440 is stored in the snap-fitting disk 41 through the pull wire 42. Further, the snap-fitting disk 40 and the actuating disk 41 lose their mutual restraint, and then under the operating force of the torsion spring 45, the snap-fitting disk 40 and the actuating disk 41 deflect.

[0070] The deflection of the snap-fit ​​disk 40 causes the wire extension assembly to move horizontally and the wire reel assembly 1 to move toward the side wall of the wire drawing machine through the action of the connecting rod A402 and the connecting rod B91. The horizontal movement of the wire extension assembly can guide the movement direction of the broken wire end and the winding, and the movement of the wire reel assembly 1 can further enhance the effect of the broken wire end being sleeved on the wire extension assembly to avoid the movement of the broken wire end of the wire body.

[0071] The deflection of the actuating disk 41 drives the wire clamping assembly 3 to work through the sliding connecting rod 43, thereby clamping the broken wire end, thereby preventing the broken wire end from moving and causing damage to components such as the wire drawing die.
