Description

Technical Field

[0001] This invention relates to the field of spring steel wire production traction equipment technology, and in particular to an instantaneous stopping device for a spring steel wire traction machine. Background Technology

[0002] In the industrial production and processing of spring steel wire, the traction machine is the core equipment for the wire conveying, stretching, and straightening processes. To ensure production safety and processing accuracy, the traction equipment needs to be equipped with a stop structure to cope with sudden working conditions such as equipment failure, wire deviation, and emergency shutdown. Currently, the stop structure of existing spring steel wire traction machines mostly adopts a single hydraulic cylinder rigid clamping braking structure. The structural design is simple, but it has many defects in actual use. The traditional stop structure has poor synchronization in the clamping process, and the clamping components on both sides are prone to deviation and misalignment, resulting in uneven force on the wire clamping. This can easily cause the wire to be squeezed and deformed, surface worn, or even broken, seriously affecting the quality of the finished spring steel wire. At the same time, the existing rigid stop structure cannot buffer the impact force generated by the traction inertia of the wire during instantaneous braking. The huge instantaneous impact force not only aggravates the wear of the clamping structure and transmission components, reducing the service life of the equipment, but also easily causes problems such as stop lag and unstable locking, posing significant production safety hazards. In addition, traditional stopping devices have a single braking and reset adjustment method, which cannot flexibly switch between instantaneous stopping, rapid reset and normal traction states according to working conditions. The braking buffer adaptability is poor, making it difficult to adapt to the needs of high-speed and continuous spring steel wire traction production operations. Overall, the practicality and stability are insufficient, and it cannot meet the requirements of high-precision and high-safety spring steel wire production and processing. Summary of the Invention

[0029] like Figure 5 As shown, the synchronous transmission structure 32 includes a bevel gear 321, a transmission shaft 322, a spur gear 323, a connecting gear 324, a transmission gear 325, a connecting gear 326, a spur gear 327, a transmission shaft 328, and a bevel gear 329. The spur gear 323, connecting gear 324, transmission gear 325, connecting gear 326, and spur gear 327 are sequentially and movably connected inside the mounting base 2. The central shaft end of the transmission gear 325 is fixedly connected to the end of the transmission shaft 314, and the transmission gear 325 is connected to the connecting gear... A spur gear 324 is connected to a connecting gear 326; a spur gear 323 is connected to a connecting gear 324, a transmission shaft 322 is fixedly connected to the center of the spur gear 323, and a bevel gear 321 is fixedly connected to the end of the transmission shaft 322, and the bevel gear 321 is connected to a connecting transmission device 4; a spur gear 327 is connected to a connecting gear 326, a transmission shaft 328 is fixedly connected to the center of the spur gear 327, and a bevel gear 329 is fixedly connected to the end of the transmission shaft 328, and the bevel gear 329 is connected to a connecting transmission device 5.

[0030] like Figure 6 As shown, the connecting transmission device 4 and the connecting transmission device 5 have the same structure and are arranged in parallel. The connecting transmission device 5 includes a swing arm 51, an end face gear 52, a connecting shaft 53, a linear-to-rotation mechanism 54, and a support 55. One side of the swing arm 51 is movably connected to the inside of the mounting base 2 through the connecting shaft 53. The end face gear 52 is movably connected inside one side of the swing arm 51, and the center of the end face gear 52 is movably connected to the outside of the connecting shaft 53. The end face gear 52 is connected to the bevel gear 329. The linear-to-rotation mechanism 54 is located inside the other side of the swing arm 51. One side of the linear-to-rotation mechanism 54 is connected to the end face gear 52, and the other end of the linear-to-rotation mechanism 54 is hinged to the support 55. The support 55 is connected to the clamping mechanism 8.

[0031] like Figure 7 As shown, the linear-to-rotation mechanism 54 includes a bevel gear 541, a screw 542, a sliding hole 543, a nut block 544, and a telescopic arm 545. The sliding hole 543 is located inside the other side of the swing arm 51. The telescopic arm 545 is movably connected inside the sliding hole 543. The screw 542 is movably connected to the center of the inner side of the sliding hole 543, and the end of the screw 542 is fixedly connected to the bevel gear 541, which is connected to the end face gear 52. The nut block 544 is fixedly connected to the opening on the inner side of the telescopic arm 545, and the nut block 544 is connected to the screw 542. The outer end of the telescopic arm 545 is hinged to the support 55.

[0032] like Figure 8 As shown, the clamping mechanism 8 includes a fixed base 81, a parallel slide groove 82, a parallel block 83, a connecting groove 84, a clamping groove body 85, and a clamping slot 86. The fixed base 81 has a parallel slide groove 82 inside. There are two parallel blocks 83, which are movably connected to the upper and lower positions of the parallel slide groove 82, respectively. The inner side of each of the two parallel blocks 83 has a connecting groove 84, and the clamping groove body 85 is fixedly connected inside the connecting groove 84. The inner side of the clamping groove body 85 has a clamping slot 86. The outer sides of the two parallel blocks 83 are fixedly connected to the corresponding supports 55.

[0033] The width of the parallel block 83 is equal to the distance between the front and rear ends of the parallel groove 82. The invention is used in the following ways: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. When pulling the spring steel wire, the spring steel wire passes through the openings on both sides of the outer shell 1, conforming to the surfaces of the upper and lower sets of guide wheels 9 to complete the guiding and limiting, preventing the steel wire from shifting or shaking during traction, and ensuring the stability of the traction path. The upper and lower fixed mounting seats 2 inside the outer shell 1 provide a fixed installation benchmark for the overall transmission, buffering, and clamping structure. The synchronous buffering mechanism 3, connecting transmission device one 4, and connecting transmission device two 5 inside the two sets of mounting seats 2 are in a synchronous standby linkage state. In this state, the two hydraulic cylinders one 7 remain in a retracted state, and the piston rod of hydraulic cylinder one 7 pulls the corresponding side of the connecting transmission device two 5 through the hinged connecting block 6, causing the connecting transmission device two 5 to engage with the connecting transmission device two 5. The transmission device 4 remains in an open position, thereby driving the clamping mechanism 8 to be in a released state. The two parallel blocks 83 inside the fixed seat 81 of the clamping mechanism 8 slide and separate to both sides along the parallel slide groove 82. The clamping groove 85 fixed in the inner connecting groove 84 of the parallel blocks 83 opens synchronously. The slots 86 of the upper and lower clamping grooves 85 move away from each other and do not contact the spring steel wire passing through the middle. The steel wire can continue to move at a uniform speed under the guidance of the guide wheel 9. At the same time, the buffer structure 31 and the synchronous transmission structure 32 inside the synchronous buffer mechanism 3 are in a pre-tensioned and ready state. The buffer spring 312 inside the inner cavity 311 of the buffer structure 31 remains in a slightly compressed pre-tensioned state. The piston block 313, the long slider 316, and the rack 317 are in their initial positions. The transmission gear 3... 15. Drive shaft 1 314 is locked in place; the piston rod of cylinder 2 319 drives piston block 2 318 to contact the right side of long slider 316, completing the position limit. The drive gear 2 325, connecting gear 1 324, connecting gear 2 326, spur gear 1 323, and spur gear 2 327 inside the synchronous transmission structure 32 remain engaged and ready. The bevel gear 1 321 at the end of drive shaft 2 322 meshes with connecting transmission device 1 4, and the bevel gear 2 329 at the end of drive shaft 3 328 meshes with connecting transmission device 2 5, realizing the synchronous linkage preparation of the left and right transmission structures. Connecting transmission device 1 4 and connecting transmission device 2 5 have the same structure and operate in parallel and symmetrically. The swing arm 51 of connecting transmission device 2 5 is limited to the inside of the mounting base 2 by the connecting shaft 53. Gear 52 meshes stably with bevel gear 329. The bevel gear 541 of the internal linear-to-rotary mechanism 54 meshes with the end face gear 52 for transmission. Screw 542, nut block 544, and telescopic arm 545 are at their initial telescopic lengths. The support 55, hinged at the end of the telescopic arm 545, stably connects to the parallel block 83, reserving transmission stroke for subsequent locking actions. In case of instantaneous stop, if the traction machine malfunctions, the wire deviates, or an emergency stop is required, the device triggers the instantaneous stop function. All mechanisms are synchronized and quickly lock the spring wire, achieving a lag-free stop. First, two sets of hydraulic cylinders 7 extend synchronously, and the piston rod pushes the connecting block 6 to move, causing the two connecting transmission devices 5 to swing inward around the connecting shaft 53. Simultaneously, the linked connecting transmission device 4 retracts inward synchronously.The synchronous drive mechanism 8 of the two-sided transmission structure completes the locking. During the swinging process of the connecting transmission device 1 4 and the connecting transmission device 2 5, the two parallel blocks 83 move closer to each other in parallel, which causes the upper and lower clamping grooves 85 to close quickly. The grooves 86 tightly clamp the spring steel wire. After the moving spring steel wire is clamped momentarily, it will also drive the two parallel blocks 83 to move to the left a small distance. When the parallel blocks 83 move to the left a small distance, the telescopic arm 545 will retract along the sliding hole 543. At the same time as the telescopic arm 545 retracts, it will drive the screw 542 to rotate through the nut block 544. The rotation of rod 542 drives the end face gear 52 to rotate via bevel gear 3 541. The rotation of end face gear 52 drives the transmission shaft 3 328 and spur gear 2 327 to rotate via bevel gear 2 329. Then, the connecting gear 2 326 drives the central transmission gear 2 325 to rotate, which in turn drives the transmission shaft 1 314 and the externally fixed transmission gear 1 315 to rotate. Transmission gear 1 315 meshes with rack 317, causing the long slider 316 to slide laterally along the inner cavity 311, pushing the piston block 1 313 to compress the buffer spring 312. Through the buffer spring 312... The elastic deformation absorbs the instantaneous impact force at the moment of stopping, avoiding deformation, breakage, or wear of the equipment transmission structure caused by rigid clamping. The synchronous buffer mechanism 3 here ensures that the telescopic arms 545 in the connecting transmission device 1 4 and the connecting transmission device 2 5 can retract simultaneously for buffering, thus ensuring that the parallel block 83 is always in a horizontal state during clamping and buffering, thereby ensuring the clamping and buffering effect. After stopping, the extension of the hydraulic cylinder 2 319 allows the telescopic arms 545 in the connecting transmission device 1 4 and the connecting transmission device 2 5 to continue to retract, thus... The slots 86 in the two parallel blocks 83 quickly separate from the spring steel wire, thus not affecting the continued traction of the spring steel wire. If further stopping is required, the hydraulic cylinder 319 can be retracted, and then the telescopic arm 545 is driven to extend along the sliding hole 543 under the action of the buffer spring 312, thereby causing the two parallel blocks 83 to move closer to each other in parallel, which in turn causes the upper and lower clamping slots 85 to close quickly. The slots 86 tightly clamp the spring steel wire for a quick and instantaneous stop. If it is necessary to restore the normal traction operation state for a long time, the hydraulic cylinder 7 can be shortened to completely separate the two parallel blocks 83.
