Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal straightening, in particular to a mine steel wire rope straightening device. BACKGROUND

[0002] In the process of quality detection and performance evaluation of mine steel wire rope, physical performance test of steel wire is a crucial link. This first requires the disassembly of the complex structure of the steel wire rope and the separation of the single steel wire constituting the main body. However, these single wires released from the rope are twisted into a spiral shape due to the accumulation of significant twisting residual stress in the steel wire rope manufacturing process, which is generally severely twisted. This twisted state makes the steel wire sample unable to be directly and accurately clamped in the clamp of the testing machine, and also cannot guarantee its ideal axial stress state during the test. Therefore, before the experiment, the single steel wire must be effectively straightened.

[0003] The traditional mechanical straightening method, such as the common roll straightening (wire drawing straightening), in the process of handling high-strength single wires disassembled from mine steel wire rope, its core principle is to make the steel wire repeatedly bend or stretch between multiple staggered straightening rollers, exceed its elastic limit, and enter the plastic deformation zone, so as to eliminate the original curvature and unevenness. However, the high-speed friction or extrusion of the hard straightening roller with the steel wire surface may cause scratches, indentations, and even micro-cracks, which will affect the subsequent physical performance test.

[0004] Because the traditional mechanical straightening method has the above-mentioned unavoidable damage risk, which will seriously interfere with the accuracy of the test data and cannot reflect the real performance of the steel wire in the rope body, therefore in the pre-treatment of the physical test of the single wire of the mine steel wire rope, this kind of method is usually abandoned. Instead, a more cautious and less material intervention "manual straightening" method is used. The specific operation of the widely used "manual straightening" is usually as follows: the operator places the twisted single steel wire on a very thick hard polyurethane pad, uses a red copper hammer, and selectively and moderately knocks the convex curved parts of the steel wire along the length direction of the steel wire by observation and experience.

[0005] However, this manual straightening method relying on manual experience has significant limitations:

[0006] 1. Huge labor intensity: The physical test of mine steel wire rope often requires a large number of effective samples (dozens or even hundreds), and each steel wire needs to be finely straightened by hand. The operator needs to maintain high attention for a long time, and the repeated observation, judgment and knocking actions are extremely tiring, which can easily lead to muscle fatigue (such as arm and wrist pain) and visual fatigue, and the work is extremely hard.

[0007] 2. Extremely low efficiency: manual straightening is a highly dependent on individual skills and concentration of the serial process, and the processing of each steel wire takes a long time. In the face of large sample demand, the straightening link becomes a serious bottleneck in the whole test process, which greatly slows down the test progress. SUMMARY

The two columns 203 are slidably connected to the body 207, and a transverse upper beam 205 is installed on the top of the two columns 203. An adjusting rod 206 is rotatably connected to the middle of the upper beam 205. The adjusting rod 206 has an external thread and is threaded to the body 207. An adjusting handle is installed on the top of the adjusting rod 206. By rotating the adjusting handle, the adjusting rod 206 is rotated, thereby enabling the body 207 to move up and down along the columns 203.

[0068] It should be understood that the upper die 600 and the lower die 700 need to be adjusted in position during the installation of the straightening die, so that the upper die 600 and the lower die 700 can be aligned and then cooperate with each other to complete the stamping and straightening.

The drive wheel and the flywheel 302 are connected by a belt drive to realize power transmission.

[0073] Furthermore, the upper pressure 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. Then, the control box 400 controls the clutch 303 to close. The rotating flywheel 302 drives the crankshaft 304 to rotate. 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 machine body 207, thereby driving the upper pressure die 600 to press down and cooperate with the lower pressure die 700 to perform a straightening operation.

[0074] It should be noted that the aforementioned electrical control box 400 is electrically connected to the clutch 303, and a control switch 202 is provided on the stamping base 201. The start and stop of the drive motor 301 are controlled by the control switch 202. The specific control circuit is existing technology and will not be described in detail here.

An upper shaft 602 is installed in the center of the top surface of the upper mold base 601, and a combined cavity is opened inside the upper mold base 601. Multiple sets of upper clamping plate assemblies 604 are arranged at equal intervals in the combined cavity, and 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 provided on one side of the upper mold base 601. The upper fastening screw 1 605 and the upper fastening screw 2 606 both extend through the side wall of the upper mold base 601 into the combined cavity and are inserted into the opposite side wall of the upper mold base 601. It should be noted that the upper isolation block 603, located at the farthest point from the installation side of the upper fastening screw 605 and the upper fastening screw 606, is provided with nuts at the penetration positions of the upper fastening screw 605 and the upper fastening screw 606. The two nuts are threadedly connected to the corresponding upper fastening screw 605 and the upper fastening screw 606 to achieve fastening of multiple sets of upper clamping plate assemblies 604.

[0076] Wherein when the upper fastening screw one 605 or the upper fastening screw two 606 is inserted from the upper die seat 601 installation side, it is connected with the nut through a plurality of groups of upper isolation blocks 603 and upper clamping plate assemblies 604, drives the upper isolation block 603 farthest to the upper fastening screw one 605 and the upper fastening screw two 606 installation side to move transversely, and then fastens a plurality of groups of upper clamping plate assemblies 604, and the other end of the upper fastening screw one 605 or the upper fastening screw two 606 is inserted into the upper die seat 601 to realize longitudinal limiting during the fastening process.

[0077] Need to be explained, the slider 307 is also provided with a set screw 308, when the upper die 600 is inserted into the slider 307 through the upper shaft 602, the set screw 308 is rotated to realize the fixing of the upper die 600, and the installation of the upper die 600 is completed.

Since the hardness of the red copper sheet is smaller than that of the steel wire, the red copper sheet is used as a stamping contact piece to well protect the steel wire during stamping and straightening, and straightening is realized on the basis of avoiding damage. And after the gasket 6043 is damaged after long-term use, it can be replaced in time, which is convenient and fast. When replacing, the upper fastening screw one 605 is taken out, the upper clamping plate assembly 604 is released, the intermediate clamping plate 6042 is taken out, the gasket 6043 mounted in the mounting groove 6046 is taken out and replaced, and after replacement, the intermediate clamping plate 6042 is inserted between the two side clamping plates 6041, and the upper fastening screw one 605 is mounted to complete the replacement.

During die closing, the multiple sets of lower clamping plate assemblies 704 and the multiple sets of upper clamping plate assemblies 604 are staggered. A lower fastening screw one 705 and a lower fastening screw two 706 are provided on one side of the lower die base 702.

[0085] It should be understood that when straightening a twisted steel wire, the bent portion of the wire will exhibit a certain degree of rebound during the straightening process, such as... Figure 18 As shown in the diagram, part B represents the uncorrected state, part C represents the corrected state, and part D represents the corrected state. Figure 18 As shown in parts B, C, and D, if only the downward limit position of the shim 6043 of the upper clamping plate assembly 604 during the stamping process is controlled to remain flush with the shim 6043 of the lower clamping plate assembly 704, due to the elasticity of the steel wire, after the shim 6043 of the upper clamping plate assembly 604 returns to its original position, it will be as follows: Figures 13-16 As shown in section D, the straightened wire bounces back, making it impossible to completely straighten the arched part of the wire.

[0086] Therefore, as Figure 17As shown, the lower pressing die 700 of the embodiment further comprises a fine adjustment mechanism 701, which is arranged at the bottom of the lower die seat 702 and is magnetically connected with the lower die seat 702.

[0087] Specifically, the fine adjustment mechanism 701 comprises a fine adjustment base 7011 at the bottom, pressure strips are symmetrically arranged at both sides of the fine adjustment base 7011, and limit blocks 7014 are further arranged on the pressure strips, which cooperate with the limit grooves 2044 to limit the horizontal direction of the fine adjustment mechanism 701, and the pressure strips cooperate with the pressure grooves 2046 on the limit plates 2041 to limit the vertical direction of the fine adjustment mechanism 701.

[0088] Further, the fine adjustment base 7011 is internally provided with a movement cavity, a cylindrical gear 7015, a transmission gear 7018 and a driving gear 7019 are rotationally arranged in the movement cavity through shafts, the transmission gear 7018 and the driving gear 7019 are meshed and connected, four groups of lifting gears 7017 are symmetrically arranged at both sides of the cylindrical gear 7015, 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.

[0089] It should be further explained that the fine adjustment base 7011 is provided with a countersunk screw 7020 at a position corresponding to the lifting gear 7017, the screw rod of the countersunk screw 7020 extends into the movement cavity through the fine adjustment base 7011, and the flange nut 7016 is installed on the shaft center of the lifting gear 7017, and the flange nut 7016 is threadedly connected with the countersunk screw 7020.

[0090] During movement, the driving gear 7019 drives the transmission gear 7018 to rotate, the transmission gear 7018 drives one group of lifting gears 7017 to rotate, and then the lifting gears 7017 drive the cylindrical gear 7015 to rotate, the cylindrical gear 7015 drives the other three groups of lifting gears 7017 to rotate, and when the lifting gears 7017 rotate, the flange nut 7016 on the shaft center moves vertically on the countersunk screw 7020, and then drives the lifting gears 7017 fixedly installed with the flange nut 7016 to also lift and lower, realizing the up and down movement of the lifting gears 7017 during rotation.

[0091] Preferably, in this embodiment, a fine-tuning cover 7012 is fixedly installed on the top of the fine-tuning base 7011. The fine-tuning cover 7012 limits the cylindrical gear 7015, transmission gear 7018, and drive gear 7019 inside the fine-tuning base 7011. Furthermore, the fine-tuning cover 7012 has a lifting groove at the corresponding position of the lifting gear 7017, allowing the lifting gear 7017 to move smoothly up and down. A floating plate 7013 is further provided on the top of the fine-tuning cover 7012. A pushing platform is provided at the bottom of the floating plate 7013 at the position corresponding to the lifting groove. In the initial state, the pushing platform is located in the lifting groove and does not push. During fine-tuning, the rising lifting gear 7017 pushes the pushing platform, thereby causing the floating plate 7013 to float upwards.

[0092] It should be noted that the floating plate 7013 and the fine-tuning cover 7012 are connected by bolts. During installation, a predetermined distance is reserved between the bottom of the bolt cup head and the bottom of the groove on the floating plate 7013 as a floating limit, ensuring that the floating plate 7013 floats within a reasonable range without falling off.

[0093] Furthermore, multiple sets of magnets 7021 are installed on the top surface of the floating plate 7013. The magnetic force generated by the multiple sets of magnets 7021 stably attracts the lower die base 702. It should be noted that the magnetic force generated by the multiple sets of magnets 7021 can stably attract the lower die base 702 during the stamping and straightening process.

[0094] In this embodiment, when the upper die 600 and the lower die 700 are closed, the fine-tuning mechanism 701 adjusts the distance H between the highest point of the pad 6043 surface of the upper clamping plate assembly 604 and the lowest point of the pad 6043 surface of the lower clamping plate assembly 704, wherein the highest point of the pad 6043 surface of the upper clamping plate assembly 604 is lower than the lowest point of the pad 6043 surface of the lower clamping plate assembly 704. This is achieved by changing the stamping position difference (i.e., as shown in the figure). Figure 19 As shown in H), the stamping degree of the bent and arched part of the steel wire is increased to compensate for the rebound, making it easier and faster to complete the straightening and improve the straightening effect.

[0095] The specific process is as follows: Figure 19 As shown in the diagram, part E represents the uncorrected state, part F represents the corrected state, and part G represents the corrected state. ​E, F, G in the three parts shown, when the gasket 6043 of the upper clamp plate assembly 604 moves to the differential state, the steel wire generates reverse arching deformation at this time, after the reset of the gasket 6043 of the upper clamp plate assembly 604, the initial state of the steel wire arches back, and after the compensation of the differential stamping, the steel wire arches back to the straight state, achieving the purpose of complete straightening. As for the specific parameters of the differential H, it can be adjusted according to the bending degree of the steel wire. For example, if the upward arching deformation still exists after stamping and straightening, it means that the value of H is too small and needs to be increased. On the contrary, if the upward arching deformation becomes downward arching deformation after stamping and straightening, it means that the value of H is too large and needs to be reduced. Continuous observation and adjustment are needed to achieve the best straightening effect.

[0096] The specific working process of the embodiment is as follows:

[0097] By controlling the switch 202 to start the stamping machine, the twisted steel wire is inserted into the straightening pressing die. The operator steps on the foot switch 500, and the clutch 303 is closed by the electric control box 400. After the clutch 303 is closed, the flywheel 302 driven by the driving motor 301 drives the crankshaft 304 to rotate, and the crankshaft 304 drives the connecting rod 306 to move. The up-and-down connecting rod 306 pushes the sliding block 307 to slide, and the sliding block 307 drives the upper pressing die 600 to move downward. The upper clamp plate assembly 604 in the upper pressing die 600 cooperates with the lower clamp plate assembly 704 in the lower pressing die 700 to straighten the twisted steel wire. During the straightening process, the steel wire moves forward and backward and rotates simultaneously, changing the straightening position.

[0098] According to the observed straightening effect, the main gear 7019 is adjusted to drive the transmission gear 7018 to rotate, the transmission gear 7018 drives a group of lifting gears 7017 to rotate, and the lifting gears 7017 drive the cylindrical gear 7015 to rotate, which drives the other three groups of lifting gears 7017 to rotate, pushing the floating plate 7013, and then making the floating plate 7013 float. The floating plate 7013 drives the lower pressing die 700 to move up and down, fine-tunes the distance between the upper pressing die 600 and the lower pressing die 700, and then adjusts the straightening effect.

[0103] Third, automatic: press the foot switch 500, the upper die 600 continues to move, and press the foot switch 500 again, the upper die 600 stops moving.
