Description

Technical Field

[0001] The invention belongs to the technical field of shearing machine clutch system adjustment, and in particular relates to a quick adjustment method for a friction plate shearing machine clutch system. Background Art

[0002] In order to ensure production quality and eliminate safety hazards, medium plate mills need to regularly maintain and adjust friction plate shears. As the thickness of the plates sheared by the medium plate mills increases and the output increases, the wear of the friction plate shears increases further. The adjustment cycle of the shearing machine clutch system is shortened, and an average of 2 adjustments are required per month. The total adjustment time increases, affecting the production rhythm.

[0003] Traditional friction plate clearance adjustment methods require simultaneous adjustment of the shear and brake side clearances, requiring repeated adjustments. This consumes significant labor and time, often leading to clearance errors and the need for further downtime for adjustment. During downtime, the flywheel must be brought to a stable, free-standing position, which is time-consuming and difficult to perform, significantly impacting the plate mill's production schedule. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: how to realize the fast adjustment of the clutch system of the shearing machine, save the adjustment time and improve the one-time success rate of the adjustment.

[0005] To achieve the above object, the technical solution of the present invention is:

[0006] In a first aspect, the present invention provides a method for quickly adjusting a clutch system of a friction plate shearing machine, comprising the following steps:

[0007] Cut off the main power supply of the shearing machine, close the solenoid valve, release the residual energy on the flywheel, and position the shearing machine in the maintenance position;

[0008] The clutch solenoid valve makes the cylinder in the closed state, remove the pressure plate, clear the impurities between the shear side friction plates, close and open the clutch solenoid valve cylinder several times, and adjust the shear side friction plate gap for the first time;

[0009] Obtaining position parameters and a preset adjustment distance of the shear side lever guide plate, the shear side friction plate, and the shear side adjustment ring after the first adjustment, calculating a radial displacement of the shear side adjustment ring based on the position parameters and the preset adjustment distance, determining an adjustment number of the shear side adjustment ring based on the radial displacement, and rotating the shear side adjustment ring based on the adjustment number to achieve a second adjustment of the shear side friction plate gap;

[0010] Repeat the above steps to adjust the clearance of the friction plate on the shear side to adjust the clearance of the friction plate on the brake side;

[0011] The clutch solenoid valve puts the cylinder in the closed state and installs the pressure plate.

[0012] The position parameter is: the actual measured distance between the shear side lever guide plate and the shear side friction plate, or the actual measured distance between the shear side lever guide plate and the shear side adjustment ring, or the actual measured distance between the shear side friction plate and the shear side adjustment ring.

[0013] The adjusting ring is provided with a plurality of grooves evenly distributed along the circumferential direction, and the pressing plate is installed in cooperation with the grooves.

[0014] The method for determining the number of adjustment grids of the shear side adjustment ring is as follows:

[0015] a1=M*(L11-L10) / N

[0016] Wherein, a1 is the number of adjustment grids of the shear side adjustment ring, L11 is the actual measured distance between the shear side lever guide plate and the shear side friction plate, L10 is the preset adjustment distance between the shear side lever guide plate and the shear side friction plate, M is the total number of grids of the outer ring of the shear side adjustment ring, and N is the thread size of the inner ring of the shear side adjustment ring.

[0017] The inner ring size of the adjusting ring is M378*4.

[0018] The method further includes: comparing the adjusted position parameter with a preset adjustment distance; if the adjusted position parameter corresponds to the preset adjustment distance, it indicates that the friction plate gap adjustment is completed; otherwise, repeating the steps of the adjustment method to readjust.

[0019] The pressure plate is used to fix the shear side adjustment ring, the shear side lever guide plate, the brake side adjustment ring and the brake side lever guide plate to prevent the shear side adjustment ring and the brake side adjustment ring from shifting during system operation.

[0020] The preset adjustment distance is the initial installation distance between the shear side lever guide plate and the shear side friction plate, or the initial installation distance between the shear side lever guide plate and the shear side adjustment ring, or the initial installation distance between the shear side friction plate and the shear side adjustment ring.

[0021] Beneficial effects of the present invention: The technical solution of the present invention can realize the rapid adjustment of the friction plate of the clutch system of the shearing machine. After the test, it was verified that the shearing machine adjusted by this method had normal shearing formation, normal parking position, favorable shearing and no shearing stop occurred. Compared with the traditional adjustment scheme, the technical solution described in the present invention can save 25-30 minutes of time per time, and has a high success rate of one-time adjustment. It effectively solves the problem that the traditional scheme often requires secondary shutdown adjustments, eliminates potential operational safety hazards, and improves production efficiency. The medium plate plant is a continuous production plant, and the rolling mill capacity is greater than the shearing capacity. Therefore, saving the maintenance and adjustment time of the shearing machine is to increase production time, which can increase the benefits by 500,000 to 600,000 yuan per year.

[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] Example 1

[0028] A method for quickly adjusting the clutch system of a friction plate shearing machine comprises the following steps:

[0029] Cut off the main power supply of the shearing machine, close the solenoid valve, release the residual energy on the flywheel, and position the shearing machine in the maintenance position;

[0030] The clutch solenoid valve puts the cylinder in the closed state, removes the pressure plate, clears the impurities between the shear side friction plate 1, closes and opens the clutch solenoid valve and cylinder several times, and adjusts the gap of the shear side friction plate 1 for the first time;

[0031] Obtaining position parameters and a preset adjustment distance of the shear-side lever guide plate 3, the shear-side friction plate 1, and the shear-side adjustment ring 2 after the first adjustment, calculating a radial displacement of the shear-side adjustment ring 2 based on the position parameters and the preset adjustment distance, determining an adjustment number of the shear-side adjustment ring 2 based on the radial displacement, and rotating the shear-side adjustment ring 2 based on the adjustment number to achieve a second adjustment of the clearance of the shear-side friction plate 1;

[0032] Repeat the above steps of adjusting the clearance of the shear side friction plate 1 to adjust the clearance of the brake side friction plate 4;

[0033] The clutch solenoid valve puts the cylinder in the closed state and installs the pressure plate.

[0034] The clutch solenoid valve is energized, the cylinder is ventilated, and the piston rod is pushed to close the friction plate on the shearing side, and the shearing machine has shearing ability.

[0035] The first adjustment is a coarse adjustment to reduce the friction plate gap; the second adjustment is a fine adjustment to ensure that the friction plate gap meets the power transmission requirements in actual operation.

[0036] More specifically, taking the shear side friction plate 1 as an example, the specific method of adjusting the friction plate gap is described. Figures 1 to 3 As shown, in this embodiment, the acquisition of the position parameters of the shear side lever guide plate 3, the shear side friction plate 1, and the shear side adjustment ring 2 refers to positioning with the shear side lever guide plate 3 as a reference, and measuring the actual distance L11 between the shear side lever guide plate 3 and the shear side friction plate 1; the preset adjustment distance refers to the initial installation distance between the shear side lever guide plate 3 and the shear side friction plate 1, that is, the distance L10 between the shear side lever guide plate 3 and the shear side friction plate 1 under the optimal working state of the shearing machine obtained through preliminary test verification.

[0037] In this embodiment, the inner ring size of the shear side adjustment ring 2 is M378*4, and 12 grooves are evenly arranged on the outer ring. When the shear side adjustment ring 2 rotates one circle, the radial displacement is 1 thread (4mm). Therefore, the radial displacement corresponding to the distance of rotating one groove is 0.33mm. At this time, the calculation method for the adjustment number of the shear side adjustment ring 2 is a1=(L11-L10) / 0.33.

[0038] Measure the distance L12 between the shear side lever guide plate 3 and the shear side friction plate 1 after adjustment. If L10 is the same as L12, it indicates that the displacement of the adjustment ring is adjusted correctly. Otherwise, repeat the steps of the above adjustment method.

[0039] Both the shear-side adjustment ring 2 and the brake-side adjustment ring 5 are provided with grooves evenly distributed along the circumference, and the pressure plates are mounted in conjunction with the grooves. The shear-side pressure plate secures the shear-side adjustment ring 2 and the shear-side lever guide plate 3, while the brake-side pressure plate secures the brake-side adjustment ring 5 and the brake-side lever guide plate 6. The pressure plates effectively prevent the adjustment rings from shifting during system operation, which could cause changes in the friction pad clearance.

[0040] Example 2

[0041] In a possible embodiment, the obtaining of the position parameters of the shear side lever guide plate 3, the shear side friction plate 1, and the shear side adjustment ring 2 refers to positioning with the shear side lever guide plate 3 as a reference, and measuring the actual distance L21 between the shear side lever guide plate 3 and the shear side adjustment ring 2; the preset adjustment distance refers to the initial installation distance between the shear side lever guide plate 3 and the shear side adjustment ring 2, that is, the distance L20 between the shear side lever guide plate 3 and the shear side adjustment ring 2 under the optimal working state of the shearing machine obtained through preliminary test verification.

[0042] The other steps are the same as those in Example 1 and will not be repeated here.

[0043] Example 3

[0044] In a possible embodiment, the obtaining of the position parameters of the shear side lever guide plate 3, the shear side friction plate 1, and the shear side adjustment ring 2 refers to positioning with the shear side lever guide plate 3 as a reference, and measuring the actual distance L31 between the shear side friction plate 1 and the shear side adjustment ring 2; the preset adjustment distance refers to the initial installation distance between the shear side friction plate 1 and the shear side adjustment ring 2, that is, the distance L30 between the shear side friction plate 1 and the shear side adjustment ring 2 under the optimal working state of the shearing machine obtained through preliminary test verification.

[0045] The other steps are the same as those in Example 1 and will not be repeated here.

[0046] In summary, the present invention changes the axial position by rotating the threaded adjustment ring, pushing the pressure plate to apply pressure to the friction plate or release the gap, thereby compensating for the travel loss caused by the wear of the friction plate. The technical solution of the present invention can realize the rapid adjustment of the friction plate of the clutch system of the shearing machine. After testing and verification, the shearing machine adjusted by this method has normal shearing formation, normal parking position, favorable shearing and no shearing stop occurs. Compared with the traditional adjustment scheme, the technical solution described in the present invention can save 25-30 minutes of time at a time, and has a high success rate of one-time adjustment. It effectively solves the problem that the traditional scheme often requires secondary shutdown adjustments, eliminates potential operational safety hazards, and improves production efficiency. The medium plate plant is a continuous production plant, and the rolling mill capacity is greater than the shearing capacity. Therefore, saving the maintenance and adjustment time of the shearing machine is equivalent to increasing production time, which can increase the benefits by 500,000 to 600,000 yuan per year.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
