Description

Technical Field

[0001] The invention relates to the technical field of metal straightening, in particular to a mining wire rope straightening device. Background Art

[0002] During the quality inspection and performance evaluation of mining wire ropes, physical property testing of the wire is a crucial step. This first requires disassembling the complex structure of the wire rope to separate the individual wires that comprise its core. However, these individual wires, released from the strands, have accumulated significant residual stress due to multiple twisting steps during the wire rope manufacturing process (typically twisting wires into strands and strands into ropes). This results in a generally severely twisted, helical shape. This twisted state prevents the wire specimen from being directly and accurately clamped in the testing machine's fixture, nor can it maintain the ideal axial load during testing. Therefore, effective straightening of the individual wires is essential before testing.

[0003] Traditional mechanical straightening methods, such as the common roller straightening (wire drawing straightening), work with high-strength monofilaments extracted from mining wire ropes. The core principle is to repeatedly bend or stretch the wire between multiple staggered straightening rollers, pushing it beyond its elastic limit and into the plastic deformation zone, thereby eliminating the original curvature and unevenness. However, the high-speed friction or compression between the rigid straightening rollers and the wire surface can cause scratches, indentations, and even microcracks. These surface defects can affect subsequent physical performance testing.

[0004] Because traditional mechanical straightening methods carry the aforementioned unavoidable risk of damage, they can severely interfere with the accuracy of test data and fail to reflect the true performance of the steel wire within the rope body. Therefore, these methods are generally abandoned in the pre-treatment of single filaments in mining wire rope physical testing. Instead, they are replaced by the more cautious "artificial straightening" method, which involves less material intervention. The currently widely used "artificial straightening" method typically operates as follows: the operator places the twisted single steel wire on a thick, hard polyurethane pad and, using a copper hammer, selectively strikes the raised, curved areas of the wire along its length, based on observation and empirical judgment, with moderate force.

[0005] However, this manual straightening method that relies on human experience has significant limitations: 1. Intense Labor Intensity: Physical testing of mining wire ropes often requires a large number of valid specimens (dozens or even hundreds), each of which requires meticulous manual straightening. Operators must maintain high concentration for extended periods, performing repetitive observation, judgment, and tapping movements, which can easily lead to muscle fatigue (such as arm and wrist soreness) and visual fatigue, making the work extremely arduous.

[0006] 2. Extremely low efficiency: Manual straightening is a serial process that relies heavily on individual skill and focus, and processing each wire takes a long time. When faced with large-volume test specimens, straightening becomes a serious bottleneck in the entire testing process, significantly slowing down testing progress. Summary of the Invention

[0014] As a further solution of the present invention: the hardness of the liner is lower than the hardness of the steel wire; The liner includes a copper sheet.

[0015] As a further solution of the present invention: the lower pressing die includes a fine-tuning mechanism, the top of the fine-tuning mechanism is magnetically attracted to a lower die base, and multiple groups of the lower clamping plate assemblies are arranged in the lower die base; The fine-tuning mechanism includes a fine-tuning base and a fine-tuning base cover, a floating plate is installed on the fine-tuning base cover, and an adjustment component is arranged inside the fine-tuning base; The position of the floating plate is adjusted by adjusting the assembly.

[0016] As a further solution of the present invention: the adjustment assembly includes a cylindrical gear, a transmission gear and a driving gear respectively rotating through a rotating shaft and arranged inside the fine-tuning base; Four groups of lifting gears are symmetrically arranged on both sides of the cylindrical gear.

[0019] The limiting plates on both sides of the present invention limit the horizontal direction of the lower pressing die through the limiting grooves, and at the same time limit the upper and lower pressing die through the pressing grooves, thereby realizing the installation alignment of the upper and lower pressing dies and improving the consistency of straightening the twisted steel wire.

[0020] The present invention provides a V-shaped mounting groove in the punching groove of the middle splint, into which a liner can be removably installed. The liner has a lower hardness than the steel wire, and, for example, copper sheets can be used to effectively protect the steel wire during the punching and straightening process, achieving straightening without damaging it. Furthermore, if the liner becomes damaged after prolonged use, it can be replaced promptly, making it quick and convenient.

By changing the stamping position difference, the stamping degree of the bent part of the steel wire is increased to compensate for the rebound that occurs, and straightening is completed more conveniently and quickly, thereby improving the straightening effect.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figure 1 As shown, the present invention provides a mining wire rope straightening device, which includes a straightening base 100, a punching machine is arranged on the top of the straightening base 100, and a straightening die is installed inside the punching machine, and a foot switch 500 is arranged on the outside of the straightening base 100. The foot switch 500 is electrically connected to the punching machine and is used to control the punching action, so as to straighten the twisted steel wire disassembled from the mining wire rope through the straightening die.

[0028] Mechanical straightening is achieved by combining a straightening die with a punching machine, thereby replacing the widely used "manual straightening", reducing the operator's labor intensity. Mechanical straightening is not affected by the operator's own factors such as individual skills, concentration, physical fitness, etc. The processing time of each steel wire is shortened, greatly improving the processing efficiency.

[0029] Example 1

[0030] like Figure 1 As shown, the straightening base 100 in this embodiment includes a base body, and four corners of the bottom of the base body are provided with Forma wheels 101. The straightening base 100 can be stably placed on the ground by adjusting the Forma wheels 101.

[0031] like Figure 2-Figure 4 As shown, the punching machine in this embodiment includes a main body component 200 installed on the top of the straightening base 100, and a driving component 300 is provided on the main body component 200, which drives the main body component 200 to move, and an electric control box 400 is installed on one side of the main body component 200 for controlling the punching action of the main body component 200 (including multiple punching modes), wherein the foot switch 500 can be connected to the electric control box 400 by a wire.

[0032] It should be noted that the control circuit and control logic of the above-mentioned electric control box 400 are both existing technologies and will not be described in detail here.

[0033] like Figure 1As shown, the straightening die in this embodiment includes an upper die 600 and a lower die 700 mounted on the main assembly 200. The upper die 600 and the lower die 700 cooperate to perform straightening by stamping through the movement of the main assembly 200. The mechanical stamping of the upper die 600 and the lower die 700 allows for control of stamping parameters such as pressure and distance, further improving the consistency of straightening the twisted steel wire.

[0034] Preferably, if Figure 2-Figure 4 As shown, the above-mentioned main body component 200 includes a stamping base 201, which can be fixedly connected to the top of the straightening base 100 by bolts or the like. Columns 203 are symmetrically arranged at both ends of one side of the top of the stamping base 201. The two columns 203 cooperate to slide and connect the body 207, and a horizontal upper beam 205 is installed on the top of the two columns 203. An adjustment rod 206 is rotatably connected to the middle of the upper beam 205. The adjustment rod 206 is provided with an external thread, and the adjustment rod 206 is threadedly connected to the body 207. An adjustment handle is installed on the top of the adjustment rod 206. The adjustment handle is rotated to drive the adjustment rod 206 to rotate, thereby realizing the up and down movement of the body 207 along the column 203.

[0035] It should be understood that during the installation of the straightening die, the upper die 600 and the lower die 700 need to be aligned so that the upper die 600 and the lower die 700 can be aligned and then cooperate with each other to complete the stamping straightening.

[0036] Therefore, Figure 1-Figure 7 As shown, in order to achieve alignment adjustment of the upper die 600 and the lower die 700, a limiting component 204 is provided on the stamping base 201 in this embodiment. The limiting component 204 is used to position and install the straightening die, making the straightening action more precise. The above-mentioned limiting assembly 204 includes limiting plates 2041 located on both sides of the lower die 700, and the two limiting plates 2041 are symmetrically distributed about the center line of the lower die 700 along the length direction, and a positioning bolt 2042 is installed on each limiting plate 2041, and the positioning bolt 2042 is set through the limiting plate 2041, and a locking nut 2043 is installed on the top surface of the limiting plate 2041, and a sliding boss 2045 is set on the bottom surface of the limiting plate 2041 along the length direction perpendicular to the lower die 700, and a limiting groove 2011 is set horizontally through the top surface of the stamping base 201, and the limiting plates 2041 on both sides slide in the limiting groove 2011 through the sliding boss 2045.

[0037] Preferably, the above-mentioned limiting groove 2011 is set in an inverted T shape, and the cup head of the positioning bolt 2042 connected to the limiting plate 2041 slides in the limiting groove 2011. It should be noted that the cup head of the positioning bolt 2042 is cut to avoid interference according to the size of the limiting groove 2011.

[0038] Preferably, the above-mentioned limiting plate 2041 is provided with a pressing groove 2046 at the bottom of the side close to the lower die 700, and a limiting groove 2044 is provided on the same side of the pressing groove 2046. The limiting plates 2041 on both sides limit the lower die 700 in the horizontal direction through the limiting groove 2044, and at the same time limit the lower die 700 in the vertical direction through the pressing groove 2046, thereby realizing the installation and alignment of the upper die 600 and the lower die 700.

[0039] Preferably, if Figure 2-Figure 4 As shown, the drive assembly 300 of this embodiment includes a mounting base (such as Figure 4 As shown), the drive motor 301 is fixedly mounted on the mounting seat, and the front of the body 207 (with Figure 1 A crankshaft 304 is rotatably mounted (facing the observer). A connecting rod seat 305 is mounted in the middle of crankshaft 304. A connecting rod 306 is connected to the bottom of connecting rod seat 305. A slider 307 is attached to the bottom of connecting rod 306. Slider 307 is slidably mounted on the body 207. One end of crankshaft 304 passes through body 207 and is connected to clutch 303. The other end of clutch 303 is mounted to flywheel 302. A drive wheel is also mounted on drive motor 301. This drive wheel and flywheel 302 are connected via a belt drive to achieve power transmission.

[0040] Furthermore, the upper die 600 is installed at the bottom of the slider 307. By starting the drive motor 301, the drive motor 301 drives the flywheel 302 to rotate, and then the closed clutch 303 is controlled by the electronic control box 400. The rotating flywheel 302 drives the crankshaft 304 to rotate, and the crankshaft 304 drives the connecting rod 306 to move. The connecting rod 306 drives the slider 307 to slide up and down along the slide groove on the body 207, and then drives the upper die 600 to press down and cooperate with the lower die 700 to perform straightening operations.

[0041] It should be noted that the above-mentioned electric control box 400 is electrically connected to the clutch 303, and a control switch 202 is provided on the stamping base 201, which controls the start and stop of the drive motor 301. The specific control circuit is the existing technology and will not be described here.

[0042] Preferably, if Figure 7-11As shown, the upper die 600 in this embodiment includes an upper die base 601, with an upper shaft 602 mounted in the middle of the top surface of the upper die base 601. A combination cavity is defined within the upper die base 601, within which multiple sets of upper clamping plate assemblies 604 are evenly spaced. Adjacent upper clamping plate assemblies 604 are isolated and adjusted by upper isolation blocks 603. An upper fastening screw 1 605 and an upper fastening screw 2 606 are also disposed on one side of the upper die base 601. Both upper fastening screw 1 605 and upper fastening screw 2 606 extend through the side wall of the upper die base 601 into the combination cavity and engage with the opposite side wall of the upper die base 601. It should be noted that a nut is provided at the position through which the upper fastening screw 1 605 and the upper fastening screw 2 606 pass, corresponding to the upper isolation block 603 at the farthest end from the installation side of the upper fastening screw 1 605 and the upper fastening screw 2 606. The two nuts are threadedly connected to the corresponding upper fastening screw 1 605 and the upper fastening screw 2 606 to achieve the fastening of multiple groups of upper clamping plate assemblies 604.

[0043] When the upper fastening screw 1 605 or the upper fastening screw 2 606 is inserted from the installation side of the upper mold base 601, it passes through multiple groups of upper isolation blocks 603 and the upper clamping plate assembly 604 and is threadedly connected to the nut, driving the upper isolation block 603 farthest from the installation side of the upper fastening screw 1 605 and the upper fastening screw 2 606 to move laterally, thereby tightening the multiple groups of upper clamping plate assemblies 604. At the same time, during the tightening process, the other end of the upper fastening screw 1 605 or the upper fastening screw 2 606 is inserted into the upper mold base 601 to realize longitudinal limitation.

[0044] It should be noted that a set screw 308 is also provided on the slider 307. When the upper die 600 is inserted into the slider 307 through the upper shaft 602, the set screw 308 is rotated to fix the upper die 600, thereby completing the installation of the upper die 600.

[0045] Preferably, if Figure 10 and Figure 11 As shown, the upper splint assembly 604 in this embodiment includes side splints 6041 located on both sides and an intermediate splint 6042 located in the middle, and stamping grooves are provided in the middle of the side splints 6041 and the intermediate splint 6042, and arc avoidance grooves are also provided at the bottom of the stamping grooves of the side splints 6041 on both sides to avoid contact with the steel wire during stamping and damage to the steel wire.

[0046] Furthermore, a V-shaped mounting groove 6046 is provided in the stamping groove of the middle clamping plate 6042. A liner 6043 is detachably mounted in the mounting groove 6046. In this embodiment, the liner 6043 can be made of a copper sheet. Since the copper sheet is less hard than the steel wire, the copper sheet is used as the stamping contact piece. This can effectively protect the steel wire during the stamping and straightening process, thereby achieving straightening without damaging it. Furthermore, if the liner 6043 is damaged after long-term use, it can be replaced in a timely manner, which is convenient and quick. When replacing, remove the upper fastening screw 605, release the upper clamping plate assembly 604, remove the middle clamping plate 6042, remove the liner 6043 installed in the mounting groove 6046, and replace it. After replacement, insert the middle clamping plate 6042 between the two side clamping plates 6041, and then install the upper fastening screw 605 to complete the replacement.

[0047] It is further noted that the intermediate plate 6042 of this embodiment is provided with a connecting groove 6045 and a guide groove 6044. The guide groove 6044 is located at the bottom and is U-shaped with an opening facing downward. The guide groove 6044 cooperates with the second upper fastening screw 606 to suspend and position the intermediate plate 6042 and facilitate disassembly. The connecting groove 6045 cooperates with the first upper fastening screw 605 to achieve connection to the intermediate plate 6042.

[0048] It should be further explained that two groups of through holes are vertically opened on the side clamping plate 6041 in this embodiment, and the two groups of through holes are adapted to the upper fastening screw 1 605 and the upper fastening screw 2 606, so that the upper fastening screw 1 605 or the upper fastening screw 2 606 can smoothly pass through each group of upper clamping plate assemblies 604, thereby realizing the installation of multiple groups of upper clamping plate assemblies 604.

[0049] Preferably, if Figure 12 As shown, the lower die 700 in this embodiment includes a lower die base 702, which has a combination cavity defined therein. Multiple sets of lower clamping plate assemblies 704 are evenly spaced within the combination cavity of the lower die base 702, and the multiple sets of lower clamping plate assemblies 704 are isolated by lower isolation blocks 703. The specific structure of the lower clamping plate assemblies 704 is consistent with that of the upper clamping plate assemblies 604. When the mold is closed, the multiple sets of lower clamping plate assemblies 704 are interlaced with the multiple sets of upper clamping plate assemblies 604. A lower fastening screw 1 705 and a lower fastening screw 2 706 are provided on one side of the lower die base 702. It should be noted that both the lower fastening screw 1 705 and the lower fastening screw 2 706 extend through the side wall of the lower die base 702 into the combination cavity and are plugged into the opposite side wall of the lower die base 702.

[0050] Among them, the lower isolation block 703 farthest from the installation side of the lower fastening screw 1 705 and the lower fastening screw 2 706 is provided with a nut corresponding to the penetration position of the lower fastening screw 1 705 and the lower fastening screw 2 706. The two nuts are threadedly connected with the corresponding lower fastening screw 1 705 and the lower fastening screw 2 706 to achieve the fastening of multiple groups of lower clamping plate assemblies 704.

[0051] The fastening method of the lower fastening screw rod 1 705 and the lower fastening screw rod 2 706 is the same as the fastening method of the upper fastening screw rod 1 605 and the upper fastening screw rod 2 606 , and will not be described in detail here.

[0052] It should be understood that when straightening a twisted steel wire, the bent portion of the steel wire will rebound to a certain extent during the straightening process, such as Figure 18 As shown in the figure, part B is the unstraightened state, part C is the straightened state, and part D is the straightened state. Figure 18 As shown in the three parts B, C, and D in FIG, if only the liner 6043 of the upper clamping plate assembly 604 is controlled to keep flush with the liner 6043 of the lower clamping plate assembly 704 during the stamping process, the liner 6043 of the upper clamping plate assembly 604 will be reset after the steel wire has a certain elasticity. Figure 18 As shown in the middle portion D, the straightened steel wire rebounds, making it impossible to completely straighten the arched portion of the steel wire.

[0053] Therefore, Figure 13-16 As shown, the lower die 700 of this embodiment further includes a fine-tuning mechanism 701 , which is disposed at the bottom of the lower die base 702 and is magnetically connected to the lower die base 702 .

[0054] Specifically, the above-mentioned fine-tuning mechanism 701 includes a fine-tuning base 7011 located at the bottom, and pressure strips are symmetrically arranged on both sides of the fine-tuning base 7011, and limiting blocks 7014 are also arranged on the pressure strips on both sides. The limiting blocks 7014 cooperate with the above-mentioned limiting grooves 2044 to achieve horizontal limitation of the fine-tuning mechanism 701, and at the same time, the vertical limitation of the fine-tuning mechanism 701 is achieved by cooperating between the pressure strips on both sides and the pressure grooves 2046 on the limiting plates 2041 on both sides.

[0055] Furthermore, a motion cavity is provided inside the fine-tuning base 7011, in which a cylindrical gear 7015, a transmission gear 7018 and a driving gear 7019 are respectively arranged to rotate through a rotating shaft, wherein the transmission gear 7018 and the driving gear 7019 are meshed and connected, and four groups of lifting gears 7017 are symmetrically provided on both sides of the cylindrical gear 7015, and the four groups of lifting gears 7017 are all meshed and connected with the cylindrical gear 7015, and one group is meshed and connected with the transmission gear 7018 for power transmission.

[0056] It should be further explained that in this embodiment, a countersunk screw 7020 is installed at the position of the fine-tuning base 7011 corresponding to the lifting gear 7017, the screw portion of the countersunk screw 7020 passes through the fine-tuning base 7011 and extends into the motion cavity, and a flange nut 7016 is installed on the axis of the lifting gear 7017, and the flange nut 7016 is threadedly connected to the countersunk screw 7020.

[0057] During movement, the driving gear 7019 is driven to drive the transmission gear 7018 to rotate, and the transmission gear 7018 drives a group of lifting gears 7017 to rotate, and then the lifting gear 7017 drives the cylindrical gear 7015 to rotate, and the cylindrical gear 7015 drives the other three groups of lifting gears 7017 to rotate. When the lifting gear 7017 rotates, the flange nut 7016 of the axis moves vertically on the countersunk screw 7020, and then drives the lifting gear 7017 fixed with the flange nut 7016 to also move up and down, realizing the up and down movement of the lifting gear 7017 during the rotation process.

[0058] Preferably, in this embodiment, a fine-tuning seat cover 7012 is fixedly installed on the top of the fine-tuning base 7011. The fine-tuning seat cover 7012 limits the cylindrical gear 7015, transmission gear 7018, and driving gear 7019 inside the fine-tuning base 7011. The fine-tuning seat cover 7012 is provided with a lifting groove at the position corresponding to the lifting gear 7017, so that the lifting gear 7017 can be lifted and lowered smoothly. Further, a floating plate 7013 is installed on the top of the fine-tuning seat cover 7012. The bottom of the floating plate 7013 is provided with a pushing platform at the position corresponding to the lifting groove. In the initial state, there is no pushing and the pushing platform is located in the lifting groove. During fine-tuning, the rising lifting gear 7017 pushes the pushing platform, thereby causing the floating plate 7013 to float upward.

[0059] It should be noted that the floating plate 7013 is connected to the fine-tuning seat cover 7012 by bolts. During installation, a set distance is reserved between the bottom surface of the bolt cup head and the bottom of the groove on the floating plate 7013 as a floating limit to ensure that the floating plate 7013 floats within a reasonable range without falling off.

[0060] In addition, multiple groups of magnets 7021 are installed on the top surface of the floating plate 7013, and the magnetic force generated by the multiple groups of magnets 7021 can stably adsorb the lower die base 702. It should be noted that the magnetic force generated by the multiple groups of magnets 7021 can stably adsorb the lower die base 702 during the stamping and straightening process.

[0061] In this embodiment, when the upper die 600 and the lower die 700 are closed, the fine adjustment mechanism 701 is adjusted so that the distance between the highest point of the surface of the pad 6043 of the upper clamping plate assembly 604 and the lowest point of the surface of the pad 6043 of the lower clamping plate assembly 704 is H, wherein the highest point of the surface of the pad 6043 of the upper clamping plate assembly 604 is lower than the lowest point of the surface of the pad 6043 of the lower clamping plate assembly 704. By changing the position difference of the stamping (i.e., Figure 17 As shown in Figure 3, the degree of punching of the curved and arched part of the wire is increased to compensate for the rebound, making straightening more convenient and quick, and improving the straightening effect.

[0062] The specific process is as follows Figure 19 As shown in the figure, part E is the unstraightened state, part F is the straightened state, and part G is the straightened state. Figure 19 As shown in parts E, F, and G of the figure, when the pad 6043 of the upper clamping plate assembly 604 moves to the position difference state, the steel wire now experiences a reverse arching deformation. After the pad 6043 of the upper clamping plate assembly 604 is reset, the steel wire's initial arc-shaped arch rebounds. After the position difference stamping compensates, the steel wire rebounds to a relatively straight state, achieving the purpose of complete straightening. The specific parameter of the position difference H can be adjusted according to the degree of curvature of the steel wire. For example, taking the upward arch deformation of the steel wire as an example, if it is found that the upward arch still exists after stamping straightening, it indicates that the H value is too small and needs to be increased. Conversely, if the upward arch deformation is found to be a downward arch deformation after stamping straightening, the apparent H value is too large and needs to be reduced. Continuous observation and adjustment are required to achieve the optimal straightening effect.

[0063] The specific working process of this embodiment: The punching machine is activated by control switch 202, and the twisted steel wire is inserted into the straightening die. The operator then steps on foot switch 500, which controls the clutch 303 via the electrical control box 400. Once clutch 303 is engaged, flywheel 302, driven by drive motor 301, rotates crankshaft 304, which in turn drives connecting rod 306. The upward and downward movement of connecting rod 306 pushes slider 307, which in turn pushes upper die 600 downward. Upper clamping plate assembly 604 in upper die 600 cooperates with lower clamping plate assembly 704 in lower die 700 to straighten the twisted steel wire. During the straightening process, the steel wire twitches back and forth, rotating simultaneously and changing its position.

[0064] According to the observed straightening effect, the driving gear 7019 is adjusted, and the driving gear 7019 drives the transmission gear 7018 to rotate, and the transmission gear 7018 drives a group of lifting gears 7017 to rotate, and then the lifting gear 7017 drives the cylindrical gear 7015 to rotate, and the cylindrical gear 7015 drives the other three groups of lifting gears 7017 to rotate, so as to push the floating plate 7013, and then make the floating plate 7013 float. The floating plate 7013 drives the lower die 700 to move up and down, and fine-tunes the distance between the upper die 600 and the lower die 700, thereby adjusting the straightening effect.

[0065] Example 2

[0066] This embodiment provides three motion modes of the straightening device in embodiment 1: The first type is single action: step on the foot switch 500, and the upper die 600 moves once; The second type is linked motion: when the foot switch 500 is pressed and held, the upper die 600 continues to move; when the foot switch 500 is released, the upper die 600 stops moving; The third type is automatic: the upper die 600 continues to move when the foot switch 500 is stepped on once, and stops moving when the foot switch 500 is stepped on again.

[0067] This embodiment provides three motion modes, which are adjusted and controlled by the electric control box 400. The specific control logic and control circuit are prior art and will not be described in detail here.
