Description

[0002] Rolls are the main components of a steel rolling mill. In order to ensure that the steel rolling mill can produce steel that meets the requirements, the precision requirements of the rolls are usually quite high. Moreover, the precision of the rolls will decrease due to wear during the production process, and repeated regrinding is required to restore the precision.

[0003] Since the rolls are usually quite large, the center hole cannot be ground on a center hole grinding machine. Currently, the center hole is usually turned on a lathe or milled on a boring machine. This method involves a large amount of turning and a large consumption of the roll.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0064] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] like Figure 1 As shown in the preferred embodiment of this application, a method for grinding roll holes on an intelligent lathe includes:

[0066] S101: Obtain parameters of the roll to be processed;

[0067] S102: Set the number of grooves, the rolling cycle expansion parameters, and the initial turning speed according to the parameters of the roll to be processed;

[0068] S103: Establish multiple correction cycles and correction time nodes, generate turning evaluation values ​​based on correction time nodes, and generate correction instructions based on turning evaluation values.

[0069] Specifically, setting the initial single-pass turning speed includes:

[0070] Obtain the machining parameters of the previous roll to be processed, and generate a turning speed sequence V based on the machining parameters, V=(v1,v2…v…). m ), where m is the number of times the previous roll to be processed has been expanded, and v i Let be the turning speed during the i-th hole enlargement;

[0071] Generate the processing evaluation value d for the previous roll to be processed, and set the adjustment coefficient e based on the processing evaluation value d;

[0072] The initial turning speed v of the roll to be processed is generated based on the turning speed sequence V and the adjustment coefficient e;

[0073] v=e* v m ) / m.

[0074] Specifically, the number of grooves is set according to the required diameter of the roll to be processed.

[0075] Specifically, setting the parameters for the cyclic expansion of the sleeve roller includes:

[0076] The required aperture diameter is generated based on the parameters of the roll to be processed.

[0077] The number of reaming cycles and the amount of reaming per cycle are generated based on the required hole diameter.

[0078] Multiple feedback time points are set based on the number of hole enlargements;

[0079] Based on the feedback time point, obtain the real-time aperture value a1 and the corresponding expected aperture value a2;

[0080] The turning difference value b is generated based on the real-time aperture value a1 and the expected aperture value a2;

[0081] An adjustment command is generated based on the turning difference value b;

[0082] The turning speed v between the current feedback time node and the next feedback time node is set according to the adjustment command. i And the amount of hole expansion.

[0083] Specifically, a feedback time node is set according to the end time of each hole reaming process. After a hole reaming process is completed, a turning difference value is generated. If the real-time hole diameter value a1 is greater than the expected hole diameter value a2, the hole reaming amount for the next time is reduced. If the real-time hole diameter value a1 is less than the expected hole diameter value a2, the hole reaming amount for the next time is increased. The change value of the hole reaming amount is the same as the current turning difference value.

[0084] Specifically, when generating adjustment commands based on the turning difference b, the following are included:

[0085] A first turning difference value B1 and a second turning difference value B2 are preset, and B1 <B2

[0086] If the turning difference b is less than the preset first turning difference, no turning speed compensation coefficient is set; if the turning difference is greater than the preset first turning difference and less than the preset second turning difference, the turning speed compensation coefficient k is set to the preset first turning speed compensation coefficient k1; if the turning difference is greater than the preset second turning difference, the turning speed compensation coefficient k is set to the preset second turning speed compensation coefficient k2; where k2 <k1<1;

[0087] Set the turning speed v between the current feedback time node and the next feedback time node. i =k*v i-1 .

[0088] Specifically, a turning speed compensation coefficient is generated based on the real-time turning difference, and the real-time turning speed is dynamically adjusted to avoid excessive difference in a single hole enlargement process, which would affect the machining quality.

[0089] Specifically, by using a sleeve roll machining process, while keeping the original roll diameter unchanged, the specifications are gradually increased from small to large. By continuously expanding the hole, the roll is ultimately machined into the required specification and shape, thereby improving machining accuracy and reducing roll consumption.

[0090] In a preferred embodiment of this application, generating the processing evaluation value d of the previous roll to be processed includes:

[0091] Establish a sequence of turning difference values ​​B, B = (b1, b2, ..., bb) m ), where m is the number of times the previous roll to be processed has been enlarged, and b i The turning difference during the i-th hole enlargement;

[0092] If bi > 0, it is set as an outlier;

[0093] Based on the turning difference sequence B, obtain the number of outlier points m1 and the total difference Δb of the hole diameter difference;

[0094] Generate an outlier count evaluation value F1 based on the outlier count m1;

[0095] The difference evaluation value F2 is generated based on the sum of the differences Δb;

[0096] Generate a processing evaluation value d, d = n1 * F1 + n2 * F2, where n1 is the preset first weight coefficient and n2 is the preset second weight coefficient.

[0097] Specifically, the evaluation values ​​of the number of outliers F1 and the difference evaluation value F2 have the same range. The larger the number of outliers m, the larger the corresponding evaluation value of the number of outliers F1. The larger the total difference Δb, the larger the corresponding evaluation value of the difference F2. The larger the processing evaluation value, the worse the processing quality of the roll to be processed, and the higher the possibility of processing errors during each hole expansion process.

[0098] Specifically, when setting the adjustment coefficient e based on the processing evaluation value d, it includes:

[0099] The first processing evaluation value range (D1, D2), the second processing evaluation value range (D2, D3), and the third processing evaluation value range (D3, D4) are preset.

[0100] If the processing evaluation value d is within the preset first processing evaluation value range, the adjustment coefficient e is set to the preset third adjustment coefficient e3; if the processing evaluation value d is within the preset second processing evaluation value range, the adjustment coefficient e is set to the preset second adjustment coefficient e2; if the processing evaluation value d is within the preset third processing evaluation value range, the adjustment coefficient e is set to the preset third adjustment coefficient e1; and e1 <e2<e3<1。

[0101] Specifically, in the above embodiments, by presetting multiple machining evaluation value ranges and setting adjustment coefficients based on real-time machining evaluation values, the set initial turning speed v is made to better meet machining requirements and improve machining accuracy.

[0102] In a preferred embodiment of this application, establishing multiple correction cycles includes:

[0103] Generate the number of rolls to be processed and the required aperture based on the parameters of the rolls to be processed;

[0104] A first evaluation value is generated based on the number of rolls to be processed;

[0105] A second evaluation value is generated based on the required aperture diameter;

[0106] Real-time monitoring and evaluation values ​​are generated based on the first and second evaluation values;

[0107] The time interval for correction cycles is set based on the monitoring and evaluation values.

[0108] Specifically, the more rolls to be processed, the smaller the corresponding first evaluation value; the larger the required aperture, the larger the corresponding second evaluation value. The first evaluation value and the second evaluation value have the same range. The monitoring evaluation value is generated based on the weighted average of the first evaluation value and the second evaluation value. The larger the monitoring evaluation value, the longer the time interval of the correction cycle.

[0109] Specifically, when generating turning evaluation values ​​based on the correction time point, the following is included:

[0110] Obtain all processed rolls from the previous correction period and select the sampling target;

[0111] Generate a sequence of processing evaluation values ​​D, D=(d1,d2…d c ), where c is the sampling size and di is the processing evaluation value of the i-th sampling target;

[0112] Generate an initial turning evaluation value z1 based on the machining evaluation value sequence;

[0113] Generate defect evaluation values ​​for the sampling targets, and set a correction coefficient j for the turning evaluation values ​​based on the defect evaluation values;

[0114] Generate the turning evaluation value z, z=j*z1.

[0115] Specifically, based on the surface aperture of the sampled target and combined with penetrant testing, a corresponding defect evaluation value is generated. The larger the defect evaluation value, the greater the possibility that there is a problem with the current processing roll.

[0116] Specifically, when generating correction instructions based on turning evaluation values, the following are included:

[0117] A preset turning evaluation value threshold is set. If the turning evaluation value z is less than the turning evaluation value threshold, a turning speed correction coefficient g is generated based on the turning evaluation value, and g < 1.

[0118] The initial turning speed v for the next correction cycle is set according to the turning speed correction factor.

[0119] v=g*e* v m ) / m.

[0120] Specifically, the turning evaluation value threshold can be set based on historical machining parameters.

[0121] Specifically, when setting the turning evaluation value correction coefficient j based on the defect evaluation value, it includes:

[0122] Preset the first defect evaluation value range and the second defect evaluation value range;

[0123] If the defect evaluation value is within the first defect evaluation value range, the turning evaluation value correction coefficient j is set to the preset first turning evaluation value correction coefficient j1; if the defect evaluation value is within the second defect evaluation value range, the turning evaluation value correction coefficient j is set to the preset second turning evaluation value correction coefficient j2; and j2 <j1<1。

[0124] It is understood that, in the above embodiments, by setting the rolling mill cycle expansion parameters and correction cycle, and making micro-adjustments based on the processing parameters after single expansion, the processing accuracy of a single roll is ensured. At the same time, by setting the correction cycle and combining it with penetrant testing, the processing parameters are corrected based on the surface parameters of the completed roll, thereby improving the overall processing accuracy, ensuring the processing quality of the roll, and reducing the consumption of the roll.

[0125] According to the first concept of this application, a sleeve roll processing method is used to process the roll into the required specification of the hole by continuously expanding the hole size while keeping the original roll diameter unchanged. This improves the processing accuracy and reduces the consumption of the roll.

[0126] According to the second concept of this application, by setting the rolling mill cyclic enlargement parameters and correction cycle, and making micro-adjustments based on the processing parameters after individual enlargement, the processing accuracy of a single roll is ensured. At the same time, by setting the correction cycle in conjunction with penetrant testing, the processing parameters are corrected based on the surface parameters of the completed roll, thereby improving the overall processing accuracy, ensuring the processing quality of the roll, and reducing the consumption of the roll.

[0127] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
