Description

Technical Field

[0001] The invention belongs to the technical field of rolling machines, in particular to an automatic radial and axial rolling machine. Background Art

[0002] A rolling mill is a steel rolling equipment used for rolling medium and thick steel plates. The rolling mill consists of a working machine base and a transmission device. The working machine base mainly includes a rolling mill frame, a roll system, a balancing system, a press-down device and a roll changing device. The transmission device consists of a large electric motor and a reducer. Due to the development of electric motor manufacturing technology, modern ring rolling mills are usually directly driven by electric motors.

[0003] At present, enterprises often need to use rolling mills when producing and processing steel plates. Although the existing rolling mills can realize the rolling function of steel plates in actual use, their rolling structures generally adopt a fixed design, which makes it inconvenient for operators to process steel plates of different thicknesses, reducing the application scope of the rolling mill.

[0004] At the same time, the existing rolling mill often produces a large amount of debris and residue during the rolling process of steel plates, and these debris and residue will fall under the rolling structure, increasing the difficulty of subsequent cleaning for operators, so it needs to be improved.

[0005] Patent application number CN89103335.1 discloses a rolling method and a rolling machine, in which many pits are formed on the surface of the workpiece to be rolled to store lubricating liquid therein, and then rolling is performed with the lubricating liquid remaining in the pits of the workpiece. This method can reduce roller wear and reduce rolling load, but does not achieve precise control of the workpiece.

[0006] Patent application number CN200780050016.1 discloses a rolling roller that is coupled to a separately manufactured shaft and rotates together with the shaft to perform rolling operations, so that stress acts evenly around the keyway of the rolling roller, solving the problem of concentrated tensile stress. However, this method does not achieve the treatment of debris residues during the rolling process.

[0042] Among them, a collecting box 3 located between the side frames 2 is fixedly installed on the top of the base 1, and inclined blocks 4 are fixedly installed on the front and rear sides of the collecting box 3. The bottom of the inclined block 4 is fixedly connected to the top of the base 1. Due to the design of the two inclined blocks 4, the debris and residue inside the collecting box 3 can be guided so that it can be discharged smoothly.

[0043] Among them, a first power motor 18 is fixedly installed on the left side of the bottom of the inner cavity of the base 1, and a first rotating rod 19 is fixedly sleeved on the other end of the output shaft of the first power motor 18.

[0046] The working principle and use process of the present invention:

[0047] When the steel plate needs to be rolled, start the first drive motor 10, the second drive motor 28, the third drive motor 29 and the fourth drive motor 30, and control the rotation direction of the first drive motor 10, the second drive motor 28, the third drive motor 29 and the fourth drive motor 30 so that the first active rolling roller 12 and the second active rolling roller 24 rotate in the opposite direction, and the third active rolling roller 14 and the fourth active rolling roller 25 rotate in the opposite direction. At this time, with the cooperation of the first active rolling roller 12 and the second active rolling roller 24, and the cooperation of the third active rolling roller 14 and the fourth active rolling roller 25, the steel plate can be rolled well.

[0048] If the operator needs to adjust the distance between the first active rolling roller and the second active rolling roller 24, and the third active rolling roller 14 and the fourth active rolling roller 25, the first pneumatic cylinder 6 and the second pneumatic cylinder 26 are started. At this time, the operation of the first pneumatic cylinder 6 will drive the first active rolling roller 12 to rise and fall through the first movable frame 7, thereby changing the distance between the first active rolling roller 12 and the second active rolling roller 24. The operation of the second pneumatic cylinder 26 will drive the third active rolling roller 14 to rise and fall through the second movable frame 26, thereby changing the distance between the third active rolling roller 14 and the fourth active rolling roller 25, so that it can roll steel plates of different thicknesses.

[0049] When the operator needs to clean the debris and residue inside the collection box 3, the first power motor 18 and the second power motor 21 can be started. Due to the operation of the first power motor 18 and the second power motor 21, the first rotating rod 19 and the second rotating rod 22 will rotate, and the first scraper 20 and the second scraper 23 will rotate, so that the debris and residue inside the collection box 3 can be pushed out, and finally slide out by the inclined block 4, which is convenient for the operator to clean it.

[0050] Example 2

[0051] In the actual production process, there are strict regulations on the thickness of the rolled steel plate. In order to achieve accurate control of the thickness of the rolled steel plate, the applicant, based on Example 1, fixedly connects a first thickness gauge to the end of the first movable frame 7 away from the second movable frame 27 to detect the actual thickness H1 of the steel plate before rolling. When the steel plate needs to be rolled, before the steel plate enters the first active rolling roller 12 and the second active rolling roller 24, the actual thickness H1 of the steel plate is measured by the first thickness gauge. A second thickness gauge is fixedly connected to the end of the first movable frame 7 close to the second movable frame 27 to detect the thickness h1 of the steel plate after being rolled by the first active rolling roller 12 and the second active rolling roller 24. After the steel plate is rolled by the first active rolling roller 12 and the second active rolling roller 24, the thickness of the steel plate changes. The second thickness gauge is used to measure the thickness h1 of the steel plate after being rolled by the first active rolling roller 12 and the second active rolling roller 24. The third active rolling roller 14 is provided with a pressure measuring device. The instrument is used to detect the actual pressure P1 generated when the third active rolling roller 14 and the fourth active rolling roller 25 roll the steel plate. When the steel plate enters between the third active rolling roller 14 and the fourth active rolling roller 25 for rolling again, the pressure gauge is used to detect the actual pressure P1 generated during rolling. The fixed seat 5 is fixedly installed with a processor, a memory and a controller. The memory is set with the original steel plate thickness value H0, the actual required steel plate thickness h0, and the set rolling pressure P0. The processor compares and calculates the results measured by the first thickness gauge, the second thickness gauge and the pressure gauge with the original steel plate thickness H0, the actual required steel plate thickness h0, and the set rolling pressure P0 set in the memory respectively. The controller controls the lifting of the first pneumatic cylinder 6 and the second pneumatic cylinder 26 according to the data transmitted by the processor, and adjusts the movement amount ΔS1 of the first movable frame 7 and the movement amount ΔS2 of the second movable frame 27. The specific adjustment amount of the movement amount ΔS1 of the first movable frame 7 and the movement amount ΔS2 of the second movable frame 27 is:

[0052] When the actual thickness of the steel plate before rolling is not less than the set original steel plate thickness, that is:

[0053] When H1-H0≥0,

[0054] Then the movement amount of the first movable frame 7 ΔS1=(H1-H0)M / K,

[0055] The movement amount of the second movable frame 27 ΔS2 = (h1-h0)-(P0-P1) / K;

[0056] Among them, H0 is the set original steel plate thickness, H1 is the actual thickness of the steel plate before rolling, ΔS1 is the movement amount of the first movable frame 7, ΔS2 is the movement amount of the second movable frame 27, h0 is the actual required steel plate thickness, h1 is the thickness after rolling by the first active rolling roller 12 and the second active rolling roller 24, P0 is the set rolling pressure, P1 is the actual pressure generated when rolling the steel plate, M is the plastic stiffness coefficient of the rolled steel plate, and K is the stiffness coefficient of the device.

[0057] When the actual thickness of the steel plate before rolling is less than the set original steel plate thickness, that is:

[0058] When H1-H0<0, if H1≥h0,

[0059] Then the movement amount of the first movable frame 7 ΔS1 = 0,

[0060] The movement amount of the second movable frame 27 ΔS2 = (H1-h0)-(P0-P1) / K;

[0061] If H1<h0, the steel plate is judged as defective.

[0062] That is, the movement amount of the first movable frame 7 is ΔS1=0,

[0063] The movement amount ΔS2 of the second movable frame 27 is 0.

[0064] The specific working process is:

[0065] When the steel plate needs to be rolled, the first thickness gauge is used to measure the actual thickness of the steel plate before it enters the first active rolling roller 12 and the second active rolling roller 24, and the measured actual thickness H1 of the steel plate is transmitted to the processor, and the processor compares the actual measured steel plate thickness value H1 with the set original steel plate thickness value H0. If H1-H0≥0, it means that the actual thickness of the steel plate before rolling is not less than the set original steel plate thickness. At this time, it is necessary to adjust the distance between the first active rolling roller 12 and the second active rolling roller 24 according to the difference between the actual thickness value of the steel plate and the set original steel plate thickness value. , the specific adjustment amount ΔS1 is: the movement amount of the first movable frame 7 ΔS1 = (H1-H0)M / K, wherein H0 is the set original steel plate thickness, H1 is the actual thickness of the steel plate before rolling, M is the plastic stiffness coefficient of the rolled steel plate, and K is the stiffness coefficient of the device. The processor transmits the processed result to the controller, and the controller controls the first pneumatic cylinder 6 to start. At this time, the operation of the first pneumatic cylinder 6 will drive the first active rolling roller 12 to be lowered through the first movable frame 7, and the reduction amount is ΔS1. After the distance between the first active rolling roller 12 and the second active rolling roller 24 is adjusted, the steel plate enters the initial rolling stage.

[0066] After the steel plate is rolled by the first active rolling roller 12 and the second active rolling roller 24, its thickness changes. At this time, the second thickness gauge measures the actual thickness of the steel plate after being rolled by the first active rolling roller 12 and the second active rolling roller 24, and the measured value is h1. The measured value is transmitted to the processor, and the processor compares the thickness h1 of the steel plate after initial rolling with the actual required steel plate thickness h0, and obtains the adjustment amount ΔS2 required to be adjusted between the third active rolling roller 14 and the fourth active rolling roller 25, which is specifically: the movement amount ΔS2 of the second movable frame 27 = (h1-h0)-(P0-P1) / K, wherein h0 is the actual required steel plate thickness, and h1 is the thickness after being rolled by the first active rolling roller 12 and the second active rolling roller 24. degree, P0 is the set rolling pressure, P1 is the actual pressure generated when rolling the steel plate, K is the stiffness coefficient of the device, the processor transmits the processed result to the controller, and the controller controls the second pneumatic cylinder 26 to start. At this time, the operation of the second pneumatic cylinder 26 will drive the third active rolling roller 14 to be lowered through the second movable frame 27, and the reduction amount is ΔS2. After the distance between the third active rolling roller 14 and the fourth active rolling roller 25 is adjusted, the steel plate enters between the third active rolling roller 14 and the fourth active rolling roller 25 for re-rolling. The steel plate is initially rolled by measuring the thickness before entering the rolling. The thickness of the steel plate after the initial rolling is accurately controlled again according to the feedback of the initial rolling result, thereby ensuring the accuracy of the thickness of the steel plate after rolling.

[0067] If the thickness H1 of the steel plate before rolling detected by the first thickness gauge is less than the set thickness H0 of the original steel plate, that is, H1-H0<0, then there is no need to adjust the distance between the first active pressing roller 12 and the second active pressing roller 24, that is, the steel plate is not squeezed when entering between the first active pressing roller 12 and the second active pressing roller 24. At the same time, the processor compares the thickness H1 of the steel plate before rolling with the actual required thickness h0 of the steel plate. When H1≥h0, it means that the thickness of the steel plate needs to be adjusted again. The specific adjustment amount is: the first active frame 7, the movement amount ΔS1=0, the movement amount ΔS2=(H1-h0)-(P0-P1) / K, the processor transmits the processed result to the controller, the controller controls the second pneumatic cylinder 26 to start, and drives the third active rolling roller 14 to descend through the second movable frame 27, the adjustment amount is ΔS2, after the distance between the third active rolling roller 14 and the fourth active rolling roller 25 is adjusted, the steel plate enters between the third active pressing roller 14 and the fourth active pressing roller 25 for rolling to obtain the actual required steel plate thickness h0.

[0068] If the thickness H1 of the steel plate before rolling detected by the first thickness gauge is less than the set thickness H0 of the original steel plate, that is, H1-H0<0, then there is no need to adjust the distance between the first active pressing roller 12 and the second active pressing roller 24, that is, the steel plate is not squeezed when entering between the first active pressing roller 12 and the second active pressing roller 24, and at the same time, the processor compares the thickness H1 of the steel plate before rolling with the actual required thickness h0 of the steel plate. When H1<h0, it means that the steel plate is defective, and the distance between the first rolling roller 12 and the second rolling roller 24 is not adjusted. There is no need to adjust the distance between the rolling rollers 24 and the distance between the third rolling roller 14 and the fourth rolling roller 25. The specific adjustment amount is the movement amount ΔS1=0 of the first movable frame 7 and the movement amount ΔS2=0 of the second movable frame 27. The processor transmits the processed result to the controller, and the first pneumatic cylinder 6 and the second pneumatic cylinder 26 are not started, that is, the first movable frame 7 and the second movable frame 27 do not move. The steel plate directly passes through the first rolling roller 12, the second rolling roller 24, the third rolling roller 14 and the fourth rolling roller 25 into the scrap area.

[0069] By setting up the first thickness gauge, the second thickness gauge, the pressure gauge, the processor, the memory and the controller, the thickness of the rolled steel plate can be accurately controlled, thereby improving the accuracy of the thickness of the rolled steel plate.
