Description

Technical Field

[0001] The invention belongs to the technical field of steel wire straightening, and in particular relates to a mining steel wire straightening device with an automatic wire guiding function. Background Art

[0002] In the fields of mining, building support, etc., steel wire is an important load-bearing and connecting material, and its straightness directly affects the performance and safety factor. However, due to the external force during production, transportation or storage, steel wire often bends and deforms, and needs to be straightened before it can be put into use. Traditional steel wire straightening equipment generally has the following problems: 1. The straightening effect is limited: Most equipment only straightens by unidirectional extrusion, which makes it difficult to eliminate the multi-directional bending of the steel wire, resulting in large residual stress and easy rebound after straightening.

[0003] 2. Low degree of automation: Wire guiding, straightening and cutting processes require manual intervention, which is inefficient and manual operation can easily cause length errors.

[0004] 3. Poor synchronization: Each mechanism (such as pushing, straightening, and shearing) relies on independent drive, and the movement coordination is insufficient, which can easily lead to wire jamming or inaccurate shearing position.

[0005] 4. Lack of adaptability: Equipment parameters need to be adjusted frequently for steel wires of different diameters or curvatures, which makes the operation cumbersome.

[0006] In the existing technology, although some devices try to integrate wire guiding and straightening functions, their clamping mechanism is easy to damage the surface of the wire, and the straightening module lacks the ability to correct at multiple angles; and the shearing mechanism mostly uses timed cutting, which cannot accurately match the straightening rhythm, resulting in material waste.

The clamping component automatically completes the clamping-pushing-releasing-resetting action through the variable depth design of the guide groove, without the need for additional sensors or control systems.

[0021] 3. Accurate segment cutting: The pulley system based on the 2:1 transmission ratio triggers shearing after completing two straightening sections, ensuring that the cutting position is always located at the junction of the straightening sections, and the material utilization rate reaches 98%. The spring-buffered shearing mechanism avoids impact damage to the blade and extends its service life.

[0022] 4. Strong compatibility and low maintenance cost: The bell-mouth design of the pretreatment head can adapt to 5-20mm diameter steel wire. The upper and lower split box structure facilitates quick maintenance of the inspection door, and the key moving parts (such as bearing seats and slide rails) are all coated with wear-resistant coatings, reducing the failure rate by 40%.

[0023] 5. Energy saving and environmental protection: A single motor drives multiple mechanisms, reducing energy consumption by 35% compared to traditional multi-motor solutions; the closed box design effectively suppresses noise and metal debris splashing.

[0024] The present invention is particularly suitable for batch processing of mine support steel wires. The straightness error of the straightened steel wire is ≤0.1mm / m, and the shear length consistency is ±0.5mm, which significantly improves the installation efficiency and safety of subsequent projects.

[0057] The working principle of the present invention is: When the straightening device is not in operation, the first sliding seat 15 is located at the frontmost 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 knife 56 and the lower shearing knife 57 are away from each other. At this time, the outer end of the second action rod 38 is inserted into the connection between the outer spiral section 21 of the guide groove 20 and the front inclined section 23.

[0058] When the bent steel wire 80 needs to be straightened, the front end of the steel wire 80 is first passed through the pretreatment head 79 and the reciprocating seat 27 and then fully extended between the two guide seats 18. After the steel wire 80 passes through the pretreatment head 79, it is initially treated by the pretreatment hole, so that the steel wire 80 with a large degree of bending is slightly straightened.

[0059] Then, the driving motor 11 is started, and the driving motor 11 drives the driving shaft 12 to rotate through the chain transmission mechanism 13, and the driving shaft 12 drives the first crank 16, the second crank 54, and the driving pulley 75 to start rotating simultaneously.

[0060] The first crank 16 drives the first sliding seat 15 to slide back and forth in the front-back direction inside the first slide rail 14 through the first connecting rod 17. The second crank 54 drives the lower jaw block 41 to slide back and forth in the vertical direction through the fifth connecting rod 55. The active drive drives the driven pulley 74 to rotate through the synchronous belt 76, and the driven pulley 74 drives the dial 77 to rotate.

[0061] When the first crank 16 starts to rotate, the first crank 16 drives the first sliding seat 15 to slide backward along the first slide rail 14 through the first connecting rod 17, and the first sliding seat 15 drives the outer cylinder 29 to slide backward through the two fixed rods 30, and the outer cylinder 29 drives the inner cylinder 28 and the reciprocating seat 27 to slide backward. When the reciprocating seat 27 slides backward, the two first action rods 34 are also driven to move backward, and the outer ends of the two first action rods 34 slide backward inside the two spiral insertion grooves 25. Under the interaction between the first action rods 34 and the insertion grooves 25, the reciprocating seat 27 starts to rotate forward on the outer cylinder 29 during the backward sliding process. When the first sliding seat 15 slides to the rearmost 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 grooves 25, so that the reciprocating seat 27 begins to rotate in the opposite direction on the outer cylinder 29 during the forward sliding process.

[0062] When the reciprocating seat 27 slides backward, the second action rod 38 is also driven to slide backward in the spiral insertion groove 19; when the reciprocating seat 27 slides forward, the second action rod 38 is also driven to slide forward in the spiral insertion groove 19. When the reciprocating seat 27 slides back and forth in the front-back direction, the outer end of the second action rod 38 is always slidably inserted in the guide groove 20, and under the action of the rebound force of the second spring 39, the outer end of the second action rod 38 is always in contact with the bottom surface of each section of the guide groove 20.

[0063] The process of the reciprocating seat 27 sliding back and forth in the front-rear direction is divided into four stages.

[0064] Phase 1: When the first crank 16 just starts to rotate, the reciprocating seat 27 slides backward a short distance, and the outer end of the second action rod 38 moves from the connection between the outer spiral 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 spiral section 22. At this time, the second action rod 38 drives the first action rod 34 to slide radially inward along the reciprocating seat 27, and 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, and the two clamping blocks 33 clamp the steel wire 80.

[0065] Phase 2: As the first crank 16 continues to rotate, the reciprocating seat 27 continues to slide backward for a distance, and the outer end of the second action rod 38 moves from the front end of the inner spiral section 22 to the rear end of the inner spiral section 22. During this process, the outer end of the second action rod 38 always slides inside the inner spiral section 22, so the two first action rods 34 are always close to each other, and the two clamping blocks 33 always clamp the steel wire 80. The reciprocating seat 27 slides backward while clamping the end of the steel wire 80, thereby driving the steel wire 80 to slide backward for a distance, thereby achieving the backward wire guiding of the steel wire 80. Since the reciprocating seat 27 keeps rotating in the forward direction during the backward sliding process, the steel wire 80 is also driven to keep rotating in the forward direction, so that the steel wire 80 is rotated ninety degrees.

[0066] Phase 3: As the first crank 16 continues to rotate, the reciprocating seat 27 slides backward a short distance again, and the outer end of the second action rod 38 moves from the connection between the rear inclined section 24 and the inner spiral section 22 along the rear inclined section 24 to the connection between the rear inclined section 24 and the outer spiral section 21. Since the depth of the connection between the rear inclined section 24 and the outer spiral section 21 is greater than the depth of the rear inclined section 24 near the end of the outer spiral section 21, the outer end of the second action rod 38 will not return to the rear inclined section 24 after entering the outer spiral section 21. In this process, the first action rod 34 slides radially outward along the reciprocating seat 27 under the action of the rebound force of the first spring 36, and the two first action rods 34 move away from each other, and the two first action rods 34 drive the two clamping blocks 33 to move away from each other, and the two clamping blocks 33 loosen the ends of the steel wire 80.

[0067] Phase 4: As the first crank 16 continues to rotate, the reciprocating seat 27 begins to slide forward, and the outer end of the second action rod 38 moves from the rear end of the outer spiral segment 21 to the front end of the outer spiral segment 21, and enters the connection between the outer spiral segment 21 and the front inclined segment 23. Since the depth of the connection between the outer spiral segment 21 and the front inclined segment 23 is greater than the depth of the front end of the outer spiral segment 21, the outer end of the second action rod 38 will not be retracted into the outer spiral segment 21. In this process, the two clamping blocks 33 remain disengaged from the steel wire 80, and the reciprocating seat 27 returns to the initial frontmost position. The reciprocating seat 27 keeps rotating in the opposite direction during the forward sliding process, so that the reciprocating seat 27 rotates to the initial angle.

[0068] As the first crank 16 starts to rotate for the next circle, the two clamping blocks 33 continue to clamp the steel wire 80 and drive the steel wire 80 to move toward the rear side, so that the steel wire 80 is pushed backward again for a distance, and then the two clamping blocks 33 release the steel wire 80, and the reciprocating seat 27 returns to the initial frontmost position, thereby realizing the uninterrupted pushing of the steel wire 80. During each pushing process, the steel wire 80 rotates 90 degrees.

[0069] 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.

[0070] When the second crank 54 drives the lower jaw block 41 to slide back and forth in the vertical direction through the fifth connecting rod 55, the lower jaw block 41 also drives the upper jaw block 40 to move synchronously through 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 fit together.

[0071] When the reciprocating seat 27 is in the first stage of the initial push, the upper jaw block 40 and the lower jaw block 41 start to move away from each other from the mutually engaged state. When the reciprocating seat 27 is in the second stage of the initial push, the reciprocating seat 27 pushes the steel wire 80 backward, so that the front half of the steel wire 80 is sent between the upper jaw block 40 and the front half of the lower jaw block 41, and the steel wire 80 rotates through ninety degrees, at which 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 the initial push, the two clamping blocks 33 on the reciprocating seat 27 release the steel wire 80, at which time the upper jaw block 40 and the lower jaw block 41 move away from each other to the maximum distance. When the reciprocating seat 27 is in the fourth stage of the first push, the reciprocating seat 27 no longer pushes the steel wire 80 forward, the steel wire 80 is in the current position and does not move, the upper jaw block 40 and the lower jaw block 41 approach each other, the steel 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, and the steel wire 80 is guided by the upper triangular groove 49 and the lower triangular groove 45, so that the steel wire 80 moves between the upper pressing groove and the lower pressing groove. As the upper jaw block 40 and the lower jaw block 41 approach each other and gradually fit together, the upper pressing groove and the lower pressing groove press the steel wire 80, and the first section of the front side of the steel wire 80 is straightened by the mutual extrusion of the upper jaw block 40 and the lower jaw block 41.

[0072] 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, and then the above steps are repeated, so that the first section on the front side of the steel wire 80 is straightened for the second time, and the second section on the front side of the steel wire 80 is straightened for the first time.

[0073] Since the transmission ratio between the active 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 circles, the linkage shaft 73 drives the dial 77 to rotate one circle.

[0074] After the first and second sections of the front side of the steel wire 80 are straightened, the first and second sections of the front side of the steel wire 80 have not yet extended to the rear end outside 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 rod of the linkage frame 70, so that the linkage frame 70 is dialed downward, and the linkage frame 70 drives the U-shaped rod 69 to move downward, and the fourth spring 72 is compressed. The U-shaped rod 69 drives the action plate 67 to rotate around its center point, and the action plate 67 that starts to rotate drives the middle connecting plate 59 to slide upward, and drives the lower connecting plate 60 to slide downward. The lower connecting plate 60 drives the upper connecting plate 58 to slide downward through the connecting rods 63 on the left and right sides, and the upper connecting plate 58 and the middle connecting plate 59 approach each other, and the upper shearing knife 56 and the lower shearing knife 57 approach each other until they contact each other, and the third spring 65 is compressed. The upper shearing knife 56 and the lower shearing knife 57 that approach and contact each other complete the cutting action. Since the first and second sections of the front side of the steel wire 80 have not extended to the rear end outside of the upper jaw block 40 and the lower jaw block 41 after being straightened, the first cutting action of the upper shearing knife 56 and the lower shearing knife 57 is an empty cut. As the driven pulley 74 drives the dial 77 to continue to rotate, the lever 78 is separated from the lower rod of the linkage frame 70, and the linkage frame 70 begins to slide upward under the rebound force of the fourth spring 72, 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 shearing knife 56 and the lower shearing knife 57 gradually move away from each other until the initial distance is restored.

[0075] As the drive shaft 12 starts to rotate for the third time, the reciprocating seat 27 enters the stage of pushing the steel wire 80 for the third time. The first section of the front side of the steel wire 80 is sent to the outer side of the 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.

[0076] As the drive shaft 12 starts to rotate for the fourth time, the reciprocating seat 27 enters the fourth stage of pushing the steel wire 80. The first section and the second section on the front side of the steel wire 80 are sent to the outer rear ends of the upper jaw block 40 and the lower jaw block 41. The third section on the front side of the steel wire 80 is straightened for the second time, and the fourth section on the front side of the steel wire 80 is straightened for the first time.

[0077] As the drive shaft 12 rotates for the third and fourth times, the upper shearing blade 56 and the lower shearing blade 57 complete the cutting action again, thereby cutting off the first and second sections of the front side of the steel wire 80. Then the drive shaft 12 starts the fifth and sixth rotations, the fifth and sixth sections of the front side of the steel wire 80 are straightened, and the third and fourth sections of the front side of the steel wire 80 are cut. This process is repeated continuously, and the steel wire 80 is straightened and cut off in two sections.

[0078] Each section of the steel wire 80 rotates ninety degrees during the pushing process, and each section of the steel wire 80 is straightened for the first time by the front half of the upper jaw block 40 and the lower jaw block 41 and for the second time by the rear half of the upper jaw block 40 and the lower jaw block 41. Therefore, each section 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.
