Description

Technical Field

[0001] The present invention relates to the field of vulcanization technology, and in particular to a high-efficiency vulcanization method, system, device and storage medium. Background Art

[0002] Vulcanization is an important process in rubber processing, which involves chemical cross-linking between rubber molecules to form a three-dimensional network structure, thereby significantly improving the elasticity, heat resistance, tensile strength and chemical stability of the rubber.

[0003] In the process of vulcanizing rubber, a vulcanizing machine is generally used to vulcanize the unvulcanized semi-finished products. After the rubber strips to be vulcanized are transported to the designated location by the conveyor platform of the feeding line, the multiple rubber strips are grabbed by the grabbing assembly of the feeding line and placed on the lower hot pressing plate, and then the rubber strips to be vulcanized are manually stretched to the required length, and the vulcanizing machine is started to control the upper hot pressing plate to move closer to the lower hot pressing plate until the upper hot pressing plate and the lower hot pressing plate press the rubber to be vulcanized, and then the heating medium is passed between the upper hot pressing plate and the lower hot pressing plate, and after a vulcanization cycle, the rubber to be vulcanized is subjected to a vulcanization reaction under certain temperature, time and pressure conditions.

[0004] In the process of vulcanizing the unvulcanized semi-finished products using a vulcanizer, the rubber strip to be vulcanized needs to be stretched to the required length manually and then placed in the vulcanizer for vulcanization. The rubber strip is prone to shrinkage after being stretched manually, which requires the operator to stretch the rubber strip to be vulcanized again, which prolongs the overall time of the rubber vulcanization process, thereby reducing the overall efficiency of the rubber vulcanization process.

By calculating the distance between two single area stretching position points in the same area and using it as the single area stretching position distance value, it is convenient for subsequent use.

[0160] Step S560: Calculate the difference between the single area stretching position distance value and the pressure coverage area length value and use it as the stretching position deviation distance value.

[0161] Among them, the stretching position deviation distance value refers to the deviation value corresponding to the deviation between the distance between the clamping positions and the length of the rubber strip when a single rubber strip is stretched. The difference between the stretching position distance value of a single area and the length value of the pressure coverage area is calculated and used as the stretching position deviation distance value, which is convenient for subsequent use.

[0162] Step S570: determining a stretching position deviation influence value corresponding to the stretching position deviation distance value according to the correspondence between the stretching position deviation distance value and the preset stretching position deviation influence value, and adding the stretching position deviation influence value to the stretching movement value to form a new stretching movement value.

[0163] The stretching position deviation influence value refers to the influence degree value of the deviation between the distance between the clamping positions and the length of the rubber strip on the subsequent actual stretching distance required, and the stretching position deviation influence value is obtained by querying from a database storing stretching position deviation distance values ​​and stretching position deviation influence values, and the database is obtained and stored after the test. The stretching position deviation influence value is determined by querying the stretching position deviation distance value, and the stretching position deviation influence value is added to the stretching movement value to form a new stretching movement value, thereby reducing the influence of the rubber strip width, and then improving the accuracy of the obtained stretching movement value.

[0164] Step S580: combining the single-region stretching position point with the new stretching movement value to form single-region control information, and combining the single-region control information of each region as stretching control information.

[0165] Among them, the single area control information refers to the control information when the stretching device is controlled to stretch a single rubber strip. The single area stretching position point is combined with the new stretching movement value to form the single area control information, and the single area control information of each area is combined as the stretching control information, thereby improving the accuracy of the obtained stretching control information.

[0166] exist Figure 6 In step S540, in order to further ensure the rationality of the stretching position points of the single region, it is necessary to further analyze and calculate the stretching position points of the single region. Figure 7 The steps shown are explained in detail.

[0167] Reference Figure 7 , the method for determining the stretching position point of a single area includes the following steps:

[0168] Step S541: Analyze the deviation between the width change curve of a single area and the preset width change reference curve and use it as width change information.

[0169] The width change reference curve refers to the reference curve corresponding to the width change of the rubber strip under normal circumstances, and the width change reference curve is obtained after being pre-input by the operator. The width change situation information refers to the specific change size, position and other situation information corresponding to the width change of the rubber strip. By analyzing the deviation between the width change curve of a single area and the preset width change reference curve and using it as the width change situation information, it is convenient for subsequent use.

[0170] Step S542: Retrieve the width change value, width change position point and change value based on the width change information.

[0171] Among them, the width change information includes the width change value, the width change position point and the number of change values. The width change position point refers to the position point corresponding to the width change on the rubber strip, the width change value refers to the change value corresponding to the width change position point, and the number of change values ​​refers to the number of values ​​corresponding to the width change position point. The width change value, the width change position point and the number of change values ​​are retrieved through the width change information to facilitate subsequent use.

[0172] Step S543: based on the change value, a width change position point is selected as the center initial position point, and the width change position points except the center initial position point are selected as the remaining position points.

[0173] Among them, the center initial position point refers to the position point corresponding to the middle position of the two clamping positions initially selected when the rubber strip is stretched. The width change position point is selected according to the parity of the change value. When the change value is an odd number, the middle position point of the width change position point is directly selected and used as the center initial position point. When the change value is an even number, two position points close to the middle position of the width change position point are selected, and the middle position point of the two position points is calculated as the center initial position point. Then, the width change position points except the center initial position point are used as the remaining position points, so as to facilitate subsequent use.

[0174] Step S544: Calculate the distance between the remaining position points and the center initial position point and use it as the center deviation distance value.

[0175] Among them, the center deviation distance value refers to the distance value between the position where each width changes and the selected initial center position. The distance between the remaining position points and the center initial position point is calculated and used as the center deviation distance value for convenience in subsequent use.

[0176] Step S545: Calculate the sum of the center deviation distance values ​​on both sides of the center initial position point respectively and use it as the comprehensive value of the single-side deviation distance.

[0177] Among them, the comprehensive value of the one-sided deviation distance refers to the sum of the distances between the positions where the widths change on one side of the initial center position and the initial center position. The sum of the center deviation distance values ​​on both sides of the center initial position point is calculated separately and used as the comprehensive value of the one-sided deviation distance for easy subsequent use.

[0178] Step S546: Calculate the sum of the width change values ​​on both sides of the center initial position point and use it as the comprehensive value of the unilateral change.

[0179] Among them, the comprehensive value of unilateral change refers to the sum of changes corresponding to the changes in each width on one side of the initial center position. The sum of the width change values ​​on both sides of the center initial position point is calculated separately and used as the comprehensive value of unilateral change for easy subsequent use.

[0180] Step S547: Determine the center position adjustment value based on the comprehensive value of the unilateral deviation distance on both sides of the center position point and the comprehensive value of the unilateral change.

[0181] Among them, the center position adjustment value refers to the adjustment value corresponding to the adjustment of the initial center position. By analyzing the comprehensive value of the one-sided deviation distance and the comprehensive value of the one-sided change on both sides of the center position point, the one-sided deviation distance impact value is queried for the comprehensive value based on the database obtained from the experiment, and the one-sided change impact value is queried for the comprehensive value of the one-sided change. Then, the sum of the one-sided deviation distance impact value and the one-sided change impact value on the same side is calculated and used as the comprehensive impact value on the same side. Then, the difference between the two comprehensive impact values ​​on the same side is calculated and used as the center position adjustment value for subsequent use.

[0182] Step S548: adjusting the center initial position point based on the center position adjustment value and selecting the center position point.

[0183] The center position point is selected by moving the center initial position point by a distance corresponding to the center position adjustment value, so as to facilitate subsequent use.

[0184] Step S549: Calculate the distance between the selected center position point and the length end position point and use it as the center-end distance value.

[0185] Among them, the center-end distance value refers to the distance value between the selected center position and the end position of the rubber strip. The distance between the selected center position point and the length end position point is calculated and used as the center-end distance value for convenience in subsequent use.

[0186] Step S54A: Select a position point based on the smaller value of the center-end distance value and the center position point and use it as a single area stretching position point.

[0187] Among them, by comparing the center-end distance values ​​corresponding to the two ends of the same rubber strip, and selecting the center position point corresponding to the position of the smaller center-end distance value as the single area stretching position point, the accuracy of the obtained single area stretching position point is improved.
