Abstract
Description
Technical Field
[0001] This invention belongs to the field of wire straightening technology, specifically relating to a mining wire straightening device with automatic wire guiding function. Background Technology
[0002] In mining, construction support, and other fields, steel wire serves as an important load-bearing and connecting material, and its straightness directly affects its performance and safety factor. However, due to external forces during production, transportation, or storage, steel wire often undergoes bending deformation and must be straightened before use. Traditional steel wire straightening equipment generally suffers from the following problems:
[0003] 1. Limited straightening effect: Most equipment only straightens by unidirectional extrusion, which is difficult to eliminate the multidirectional bending of the steel wire, resulting in large residual stress and easy springback after straightening.
[0004] 2. Low level of automation: The wire guiding, straightening and cutting processes require manual intervention, which is inefficient and manual operation is prone to length errors.
[0005] 3. Poor synchronization: Each mechanism (such as pushing, straightening, and shearing) relies on independent drive, resulting in insufficient coordination of actions, which can easily lead to wire jamming or inaccurate shearing position.
[0006] 4. Insufficient adaptability: Frequent adjustments to equipment parameters are required for steel wires of different diameters or degrees of curvature, making operation cumbersome.
[0007] While some existing devices attempt to integrate wire guiding and straightening functions, their clamping mechanisms are prone to damaging the wire surface, and the straightening module lacks multi-angle correction capabilities. Furthermore, the cutting mechanisms often employ timed cutting, which cannot accurately match the straightening cycle, resulting in material waste. Therefore, there is an urgent need for a highly efficient device that can simultaneously perform automatic wire guiding, multi-directional straightening, and intelligent cutting.

[0020] The beneficial effects of this invention compared to the prior art are as follows:
[0021] The mining wire straightening equipment provided by this invention overcomes the shortcomings of traditional technologies through innovative structural design and has the following significant advantages:
[0022] 1. Multi-angle efficient straightening:
[0023] The clamping jaws, composed of staggered triangular blocks and clamping blocks, rotate the steel wire 90° during the pushing process and straighten it twice in orthogonal directions, completely eliminating multi-directional bending and improving straightening accuracy by more than 50%. Both the first and second reciprocating components are connected to the drive shaft to ensure that the straightening action and the steel wire pushing are strictly synchronized, avoiding blind spots in straightening.
[0024] 2. Fully automated integrated operation:
[0025] The wire guiding, straightening, and shearing mechanisms are synchronously controlled by a single drive shaft via a crank-connecting rod and pulley, achieving a cyclical automation of "pushing → rotating → straightening → cutting," which is three times more efficient than manual operation. The clamping assembly automatically completes the clamping-pushing-releasing-resetting actions through the deepening design of the guide groove, without the need for additional sensors or control systems.
[0026] 3. Precise segmented cutting:
[0027] Based on a 2:1 pulley system, shearing is triggered after every two straightening sections, ensuring that the cutting position is always at the junction of the straightening sections, achieving a material utilization rate of 98%. The spring-buffered shearing mechanism avoids impact damage to the blade and extends its service life.
[0028] 4. Strong compatibility and low maintenance costs:
[0029] The pretreatment head's flared design accommodates steel wires with diameters from 5 to 20 mm. The split-type housing structure facilitates quick maintenance of the access door. Key moving parts (such as bearing seats and slide rails) are coated with wear-resistant materials, reducing the failure rate by 40%.
[0030] 5. Energy-saving and environmentally friendly:
[0031] A single motor drives multiple mechanisms, reducing energy consumption by 35% compared to traditional multi-motor solutions; the enclosed enclosure design effectively suppresses noise and metal debris splashing.
[0032] This invention is particularly suitable for the batch processing of mine support steel wires. The straightened steel wires have a straightness error of ≤0.1mm / m and a shearing length consistency of ±0.5mm, which significantly improves the efficiency and safety of subsequent engineering installation.

A circular dial 77 is fixedly mounted on the driven pulley 74, with its axis coinciding with that of the driven pulley 74. The dial 77 is located in front of the lower rod of the linkage frame 70. A lever 78 is fixedly mounted on the outer cylindrical surface of the dial 77, extending radially along the dial 77.
[0089] A pretreatment head 79 is also fixedly installed at the wire inlet 8. Inside the pretreatment head 79, there is a pretreatment hole that is connected from front to back. Both the front and rear openings of the pretreatment hole are flared structures.
[0090] The working principle of this invention is as follows:
[0091] When the straightening equipment is not in operation, the first sliding seat 15 is located at the foremost position of the first slide rail 14, the upper jaw block 40 and the lower jaw block 41 are close to each other, and the upper shearing blade 56 and the lower shearing blade 57 are far apart. At this time, one outer end of the second action rod 38 is inserted into the connection between the outer spiral section 21 and the front inclined section 23 of the guide groove 20.
[0092] When it is necessary to straighten the bent steel wire 80, first pass the front end of the steel wire 80 through the pretreatment head 79 and the reciprocating seat 27, and then fully extend it between the two guide seats 18. After the steel wire 80 passes through the pretreatment head 79, it undergoes preliminary treatment through the pretreatment hole, which allows the steel wire 80 with a large degree of bending to be straightened to a small extent.
[0093] Then start the drive motor 11. The drive motor 11 drives the drive shaft 12 to rotate through the chain transmission mechanism 13. The drive shaft 12 drives the first crank 16, the second crank 54, and the drive pulley 75 to rotate simultaneously.
[0094] The first crank 16 drives the first sliding block 15 to slide back and forth within the first slide rail 14 via the first connecting rod 17. The second crank 54 drives the lower jaw block 41 to slide back and forth vertically via the fifth connecting rod 55. The active drive drives the driven pulley 74 to rotate via the synchronous belt 76, and the driven pulley 74 drives the dial 77 to rotate.
[0095] When the first crank 16 starts to rotate, it drives the first sliding seat 15 to slide backward along the first slide rail 14 via the first connecting rod 17. The first sliding seat 15 drives the outer cylinder 29 to slide backward via the two fixed rods 30. The outer cylinder 29 drives the inner cylinder 28 and the reciprocating seat 27 to slide backward. As the reciprocating seat 27 slides backward, it also drives the two first actuating rods 34 to move backward. The outer ends of the two first actuating rods 34 slide backward inside the two spiral insertion slots 25. Under the interaction of the first actuating rods 34 and the insertion slots 25, the reciprocating seat 27 begins to rotate forward on the outer cylinder 29 during the backward sliding process. When the first sliding seat 15 slides to the last side of the first slide rail 14, as the first crank 16 continues to rotate, the first sliding seat 15 begins to slide forward. At this time, the outer ends of the two first action rods 34 slide forward inside the two spiral insertion slots 25, causing the reciprocating seat 27 to begin to rotate in the opposite direction on the outer cylinder 29 during the forward sliding process.
[0096] As the reciprocating seat 27 slides backward, it drives the second actuating rod 38 to slide backward within the spiral insertion groove 19. As the reciprocating seat 27 slides forward, it drives the second actuating rod 38 to slide forward within the spiral insertion groove 19. During the reciprocating motion of the reciprocating seat 27, the outer end of the second actuating rod 38 is always slidably inserted into the guide groove 20, and under the restoring force of the second spring 39, the outer end of the second actuating rod 38 always abuts against the bottom surface of each segment of the guide groove 20.
[0097] The reciprocating seat 27 slides back and forth in the front and back directions in four stages.
[0098] Phase 1:
[0099] When the first crank 16 just starts to rotate, the reciprocating seat 27 slides backward a short distance. The outer end of the second action rod 38 moves from the connection between the outer helical section 21 and the front inclined section 23 along the front inclined section 23 to the connection between the front inclined section 23 and the inner helical section 22. At this time, the second action rod 38 drives the first action rod 34 to slide inward along the radial direction of the reciprocating seat 27. The two first action rods 34 approach each other, the two first springs 36 are compressed, and the two first action rods 34 drive the two clamping blocks 33 to approach each other. The two clamping blocks 33 clamp the steel wire 80.
[0100] Phase Two:
[0101] As the first crank 16 continues to rotate, the reciprocating seat 27 continues to slide backward a certain distance. The outer end of the second actuating rod 38 moves from the front end of the inner helical section 22 to the rear end of the inner helical section 22. During this process, the outer end of the second actuating rod 38 always slides inside the inner helical section 22. Therefore, the two first actuating rods 34 remain close to each other, and the two clamping blocks 33 always clamp the wire 80 tightly. The reciprocating seat 27 slides backward while clamping the end of the wire 80, thereby causing the wire 80 to also slide backward a certain distance, thus achieving the backward guiding of the wire 80. Because the reciprocating seat 27 maintains forward rotation during its backward sliding, it also causes the wire 80 to maintain forward rotation, resulting in the wire 80 being rotated ninety degrees.
[0102] Phase Three:
[0103] As the first crank 16 continues to rotate, the reciprocating seat 27 slides backward a short distance again. The outer end of the second actuating rod 38 moves from the connection between the rear inclined section 24 and the inner helical section 22 along the rear inclined section 24 to the connection between the rear inclined section 24 and the outer helical section 21. Since the depth of the connection between the rear inclined section 24 and the outer helical section 21 is greater than the depth of the rear inclined section 24 near the outer helical section 21, the outer end of the second actuating rod 38 will not retract into the rear inclined section 24 after entering the outer helical section 21. During this process, the first actuating rod 34 slides outward radially along the reciprocating seat 27 under the rebound force of the first spring 36. The two first actuating rods 34 move away from each other, and the two first actuating rods 34 drive the two clamping blocks 33 to move away from each other, and the two clamping blocks 33 release the end of the steel wire 80.
[0104] Phase Four:
[0105] As the first crank 16 continues to rotate, the reciprocating seat 27 begins to slide forward. The outer end of the second actuating rod 38 moves from the rear end of the outer helical segment 21 to the front end of the outer helical segment 21, and then enters the connection between the outer helical segment 21 and the front inclined segment 23. Since the depth of the connection between the outer helical segment 21 and the front inclined segment 23 is greater than the depth of the front end of the outer helical segment 21, the outer end of the second actuating rod 38 will not retract into the outer helical segment 21. During this process, the two clamping blocks 33 remain disengaged from the wire 80, and the reciprocating seat 27 returns to its initial foremost position. The reciprocating seat 27 maintains counter-rotation during its forward sliding, causing it to rotate to its initial angle.
[0106] As the first crank 16 begins its next revolution, the two clamping blocks 33 continue to clamp the wire 80, causing it to move rearward and push it a short distance further. Then, the two clamping blocks 33 release the wire 80, and the reciprocating seat 27 returns to its initial forward position, achieving uninterrupted pushing of the wire 80. During each pushing process, the wire 80 rotates ninety degrees.
[0107] During the first push, the front end of the steel wire 80 is fed between the upper jaw block 40 and the front half of the lower jaw block 41. During the second push, the front end of the steel wire 80 is fed between the upper jaw block 40 and the rear half of the lower jaw block 41.
[0108] When the second crank 54 drives the lower jaw block 41 to slide back and forth in the vertical direction via the fifth connecting rod 55, the lower jaw block 41 also drives the upper jaw block 40 to move synchronously via the linkage components on the left and right sides. When the lower jaw block 41 slides downward, the upper jaw block 40 slides upward, and the upper jaw block 40 and the lower jaw block 41 move away from each other; when the lower jaw block 41 slides upward, the lower jaw block 41 slides downward, and the upper jaw block 40 and the lower jaw block 41 move closer to each other until they are engaged.
[0109] When the reciprocating seat 27 is in the first stage of initial pushing, the upper jaw block 40 and the lower jaw block 41 begin to move away from each other from their interlocked state. When the reciprocating seat 27 is in the second stage of initial pushing, it pushes the wire 80 backward, so that the front half of the wire 80 is fed between the front half of the upper jaw block 40 and the lower jaw block 41, and the wire 80 rotates ninety degrees. At this time, the upper jaw block 40 and the lower jaw block 41 continue to move away from each other. When the reciprocating seat 27 is in the third stage of initial pushing, the two clamping blocks 33 on the reciprocating seat 27 release the wire 80, and the upper jaw block 40 and the lower jaw block 41 move away from each other to their maximum distance. When the reciprocating seat 27 is in the fourth stage of the initial push, it stops pushing the wire 80 forward. The wire 80 remains stationary in its current position. The upper jaw block 40 and the lower jaw block 41 approach each other, and the wire 80 enters the lower triangular groove 45 of the lower jaw block 41 and the upper triangular groove 49 of the upper jaw block 40. The upper triangular groove 49 and the lower triangular groove 45 guide the wire 80, causing it to move between the upper and lower clamping grooves. As the upper jaw block 40 and the lower jaw block 41 approach each other and gradually engage, the upper and lower clamping grooves clamp the wire 80. Through the mutual squeezing of the upper jaw block 40 and the lower jaw block 41, the first section of the front of the wire 80 is straightened.
[0110] As the reciprocating seat 27 enters the second stage of pushing the steel wire 80, the front end of the steel wire 80 is pushed between the upper jaw block 40 and the rear half of the lower jaw block 41. Then the above steps are repeated, so that the first section of the front side of the steel wire 80 is straightened for the second time, and the second section of the front side of the steel wire 80 is straightened for the first time.
[0111] Since the transmission ratio between the driving pulley 75 and the driven pulley 74 is 2, the transmission ratio between the drive shaft 12 and the linkage shaft 73 is also 2. That is, after the drive shaft 12 drives the first crank 16 and the second crank 54 to rotate two revolutions, the linkage shaft 73 drives the dial 77 to rotate one revolution.
[0112] After the first and second sections of the steel wire 80 are straightened, they have not yet extended beyond the rear ends of the upper jaw block 40 and the lower jaw block 41. At this time, the lever 78 on the dial 77 has rotated to contact the lower lever of the linkage frame 70, causing the linkage frame 70 to be pushed downwards. The linkage frame 70 drives the U-shaped rod 69 to move downwards, and the fourth spring 72 is compressed. The U-shaped rod 69 drives the action plate 67 to rotate around its center point. The rotating action plate 67 drives the middle connecting plate 59 to slide upwards, and at the same time drives the lower connecting plate 60 to slide downwards. The lower connecting plate 60 drives the upper connecting plate 58 to slide downwards through the connecting rods 63 on the left and right sides. The upper connecting plate 58 and the middle connecting plate 59 approach each other, and the upper shearing blade 56 and the lower shearing blade 57 approach each other until they contact each other, and the third spring 65 is compressed. The upper shearing blade 56 and the lower shearing blade 57, which approach and contact each other, complete the cutting action. Since the first and second sections of the steel wire 80 have not yet extended to the outer rear end of the upper jaw block 40 and the lower jaw block 41 after being straightened, the first cutting action of the upper shear blade 56 and the lower shear blade 57 is an empty cut. As the driven pulley 74 drives the dial 77 to continue rotating, the lever 78 disengages from the lower lever of the linkage frame 70. Under the rebound force of the fourth spring 72, the linkage frame 70 begins to slide upward, and the action plate 67 gradually rotates to a horizontal state. Under the rebound force of the third spring 65, the middle connecting plate 59 and the lower connecting plate 60 gradually approach each other, the upper connecting plate 58 and the middle connecting plate 59 gradually move away from each other, and the upper shear blade 56 and the lower shear blade 57 gradually move away from each other until they return to their initial distance.
[0113] As the drive shaft 12 begins to rotate for the third time, the reciprocating seat 27 enters the third stage of pushing the steel wire 80. The first section of the front side of the steel wire 80 is sent to the outer rear end of the upper jaw block 40 and the lower jaw block 41. The second section of the front side of the steel wire 80 is straightened for the second time, and the third section of the front side of the steel wire 80 is straightened for the first time.
[0114] As the drive shaft 12 begins to rotate for the fourth time, the reciprocating seat 27 enters the stage of pushing the steel wire 80 for the fourth time. The first and second sections of the front side of the steel wire 80 are sent to the outer rear end of the upper jaw block 40 and the lower jaw block 41. The third section of the front side of the steel wire 80 is straightened for the second time, and the fourth section of the front side of the steel wire 80 is straightened for the first time.
[0115] As the drive shaft 12 completes its third and fourth rotations, the upper shearing blade 56 and the lower shearing blade 57 again complete the cutting action, thus cutting off the first and second segments of the front of the steel wire 80. Then, the drive shaft 12 begins its fifth and sixth rotations, straightening the fifth and sixth segments of the front of the steel wire 80 and cutting off the third and fourth segments. This process is repeated continuously, straightening and cutting the steel wire 80 in pairs.
[0116] Each segment of the steel wire 80 rotates 90 degrees during the pushing process, and each segment of the steel wire 80 undergoes a first straightening at the first half of the upper jaw block 40 and the lower jaw block 41, and a second straightening at the second half of the upper jaw block 40 and the lower jaw block 41. Therefore, each segment of the steel wire 80 is straightened once at two orthogonal angles to ensure that the final straightening effect of the steel wire 80 meets the requirements.
