[0002] Air conditioner casing stamping parts are components that make up the casing of the indoor and outdoor units of the air conditioner. They are usually made of metal sheets (such as galvanized steel sheets, cold-rolled steel sheets, etc.) through a stamping process.

[0003] In the related art, when using a punch press to stamp air conditioner housing parts, the required mold is determined based on the model type of the air conditioner housing stamping part. Due to the large number of air conditioner housing stamping parts, some manufacturers are unable to meet the requirement of corresponding one stamping part to one punch press.

[0063] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 3 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0064] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0065] The present application embodiment discloses an intelligent production method for air conditioner housing stamping parts, referring to Figure 1The method flow of the intelligent production method of air conditioner shell stamping parts includes the following steps:

[0066] Step S100: Obtain the production schedule and the original operation type of each punching machine.

[0067] The production plan is a schedule for the air-conditioning casing stamping parts that need to be produced. Each order can be summarized for automatic production. The production plan records the types of stamping parts that need to be produced and the corresponding quantities; the original operation type is the type of mold installed on the punch press at the current time point, that is, the type of stamping parts that the current punch press can process.

[0068] Step S101: Determine the required production type and the corresponding required production quantity of stamping parts in the production plan table.

[0069] The required production type refers to the type of stamping parts that need to be produced, and the required production quantity refers to the quantity of stamping parts that need to be produced.

[0070] Step S102: determining the operation production efficiency of the required production type according to a preset efficiency matching relationship, and performing calculations based on the operation production efficiency and the corresponding required production quantity to determine the required production duration.

[0071] Operational production efficiency refers to the operational efficiency of a single stamping part in completing the stamping operation. Different demand production types indicate different specific situations of stamping parts, and the corresponding operational production efficiency is also different. The efficiency matching relationship between the two is determined by the staff through multiple tests in advance; the demand production time is the time required to complete the production of the corresponding single stamping part in the production schedule, which is determined by dividing the demand production quantity by the operational production efficiency.

[0072] Step S103: forming a production type set according to all required production types, and continuously randomly determining subsequent operation types in the production type set according to the original operation type.

[0073] The production type set is a set consisting of all required production types. The subsequent job type is the required production type in the production type set, and there will be no duplication of subsequent job types. For example, the production type set includes A, B, and C. When the original job type is A, the randomly appearing subsequent job types can only be B and C. When the original job type is D, the randomly appearing subsequent job types can be A, B, and C.

[0074] Step S104: randomly generate type operation duration according to the original operation type and all subsequent operation types, and construct the punch operation time axis according to the original operation type, all subsequent operation types, corresponding type operation duration and preset mold change duration.

[0075] The type operation duration is the randomly generated duration of the punch press operating on the stamping parts of each operation type. When the original operation type is not in the production type set, the corresponding type operation duration can only be 0, that is, the mold is replaced directly; the mold replacement duration is the time required to replace the mold on the punch press preset by the staff, and this duration is a fixed value; the punch press operation time axis is arranged in sequence according to different operation types, and the corresponding type operation duration and mold replacement duration are used as the length of the time axis, refer to Figure 2 .

[0076] Step S105 : randomly selecting a punching operation time axis from all punching operation time axes of each punching machine as a simulation operation time axis, and determining a simulation time axis set based on all the simulation operation time axes.

[0077] A punching machine operation time axis is randomly selected as a simulation operation time axis to simulate the specific operation condition of the punching machine, which is convenient for subsequent analysis; the simulation time axis set is a set containing the simulation operation time axes of each punching machine.

[0078] Step S106: randomly generating a simulation duration in the simulation time axis set, and determining the overall production duration of each required production type according to the simulation duration.

[0079] The simulation time is the time it takes for a randomly generated simulated punch press to perform an operation, and the overall production time is the time it takes to produce stamping parts of a single demand production type under the simulation time. For example, there are two simulation operation time axes, where the first simulation time axis is A3XB3XC1 (A3 represents 3 unit times for type A stamping parts, B3 represents 3 unit times for type B stamping parts, C1 represents 1 unit time for type C stamping parts, and X represents the mold change time for mold change. In this application, the mold change time is uniformly calculated as 1 unit time), and the second simulation time axis is A3XC3XD3. When the simulation time is 5 unit times, the corresponding overall production time of type A stamping parts is 6 unit times, the overall production time of type B stamping parts is 1 unit time, the overall production time of type C stamping parts is 1 unit time, and the overall production time of type D stamping parts is 0 unit time;

[0080] Step S107: defining the simulation time axis set when the overall production duration of each required production type is consistent with the required production duration as a valid time axis set, and defining the simulation duration corresponding to the valid time axis set as a valid duration.

[0081] When the overall production duration of each required production type is consistent with the required production duration, it means that the planned production of each stamping part can be completed according to the current simulation time axis set and the corresponding simulation duration. At this time, the effective time axis set and effective duration are defined to distinguish different data for subsequent analysis.

[0082] Step S108: Determine the effective duration with the minimum value according to a preset sorting rule, define the corresponding effective time axis set as the use time axis set according to the effective duration, and control the corresponding punch press to perform operation according to the use time axis set.

[0083] The sorting rule is a method set by the staff to sort the size of the values, such as the bubble method. The sorting rule can be used to determine the effective time length with the minimum value, that is, when the punching operation is controlled according to the effective time axis set corresponding to this time, the time required to complete the planned production is the shortest. At this time, determining it as the time axis set to be used to control each punching machine can improve the overall production efficiency of the stamping parts.

[0084] After the axis is determined during the punching operation, the intelligent production method for air conditioner housing stamping parts also includes:

[0085] Step S200: determining a mold replacement period corresponding to the mold replacement duration according to the punching machine operation time axis.

[0086] The replacement period is the time period corresponding to the length of time the die on the axis is replaced during punch operation.

[0087] Step S201: Counting according to the replacement period to determine the number of mold replacements.

[0088] The number of mold changes refers to the number of times the replacement period occurs, that is, the number of times the mold on the punch press is replaced.

[0089] Step S202: Deleting the punching machine operation axis whose mold replacement times are greater than the preset allowed times.

[0090] The permitted number of times is the maximum number of times the punch press mold can be replaced during a single operation, as set by the staff. When the number of mold replacements is greater than the permitted number, it indicates that the punch press operation axis determined at this time cannot meet the operation requirements. Therefore, the corresponding punch press operation axis will be deleted, thereby reducing the frequent replacement of molds on the punch press during subsequent actual operations.

[0091] After the effective time is determined, the intelligent production method for air conditioner shell stamping parts also includes:

[0092] Step S300: Determine whether there are at least two valid time axis sets with the same and minimum valid time lengths.

[0093] The purpose of the judgment is to find out whether there are multiple valid time axis sets that meet the requirements, so as to determine the only usable time axis set.

[0094] Step S3001: If there are not at least two minimum valid time axis sets with the same valid duration, the valid time axis set corresponding to the minimum valid duration is defined as the used time axis set.

[0095] When there are not at least two valid time axis sets with the same and minimum valid duration, it means that there is only one valid time axis set that meets the requirements, and it can be determined as the used time axis set.

[0096] Step S3002: If there are at least two valid time axis sets with the same and smallest valid duration, the valid time axis set corresponding to the smallest valid duration is defined as the candidate time axis set.

[0097] When there are at least two valid time axis sets with the same and minimum valid duration, it means that there are multiple valid time axis sets that meet the requirements. At this time, they are defined as alternative time axis sets to distinguish different valid time axis sets, which is convenient for subsequent analysis.

[0098] Step S301 : determining the number of mold replacements in each simulation operation time axis of each candidate time axis set, and performing mean calculation based on each mold replacement number to determine the mean replacement number.

[0099] The mean number of replacements is the average number of times the die needs to be replaced when all punches are operating with the alternative time axis set.

[0100] Step S302: Determine the minimum number of mean replacement times according to the sorting rule, and determine the candidate time axis set corresponding to the minimum number of mean replacement times as the used time axis set.

[0101] The sorting rules can be used to determine the minimum mean replacement times, that is, the number of molds that need to be replaced is the least in the current situation, and the staff's working time is the lowest at this time. Therefore, the alternative time axis set can be determined as the used time axis set.

[0102] After the average replacement times are determined, the intelligent production method for air conditioner housing stamping parts further includes:

[0103] Step S400: Determine whether there are at least two candidate time axis sets with the same and minimum number of mean value replacements.

[0104] The purpose of the judgment is to find out whether there are multiple alternative time axis sets that meet the mean replacement number, so as to determine the time axis set to be used.

[0105] Step S4001: If there are not at least two alternative time axis sets with the same minimum number of mean replacement times, the alternative time axis set corresponding to the minimum number of mean replacement times is determined as the used time axis set.

[0106] When there are not at least two alternative time axis sets with the same and minimum number of mean replacements, it means that there is only one alternative time axis set that meets the requirements, and it can be determined as the used time axis set.

[0107] Step S4002: If there are at least two candidate time axis sets with the same minimum number of mean replacement times, the candidate time axis set corresponding to the minimum number of mean replacement times is defined as the waiting time axis set.

[0108] When there are at least two alternative time axis sets with the same and minimum number of mean replacements, it means that there are multiple alternative time axis sets that meet the requirements. At this time, they are defined as waiting time axis sets to distinguish different alternative time axis sets, which is convenient for subsequent analysis.

[0109] Step S401 : defining the maximum mold replacement times in each waiting axis set as the representative replacement times.

[0110] Define the representative number of changes to identify the most frequent die changes in each punching machine, which is convenient for subsequent analysis.

[0111] Step S402: determining the minimum representative replacement times according to the sorting rule, and determining the waiting time axis set corresponding to the minimum representative replacement times as the used time axis set.

[0112] The sorting rules can be used to determine the number of representative replacements with the smallest value, which means that the possibility of frequent mold replacements in a single punch press is low. At this time, the corresponding waiting-time axis set can be determined as the used-time axis set. When there are multiple waiting-time axis sets with the same and smallest number of representative replacements, the number of punch presses corresponding to the representative replacement times can be determined first, so as to determine the waiting-time axis set with a smaller number as the used-time axis set. When the numbers are the same, the representative replacement times can be determined from the remaining mold replacement times. This type of analysis is repeated until a unique used-time axis set is determined.

[0113] After the axis set is determined during use, the intelligent production method for air conditioner housing stamping parts also includes:

[0114] Step S500: sorting the subsequent operation types in each simulation operation timeline in the current usage timeline set from front to back according to the simulation duration values from large to small to update the simulation operation timeline.

[0115] By updating the simulation operation time axis, the operation conditions under various identical circumstances can be unified to facilitate subsequent analysis. For example, if the two simulation operation time axes are A2XB3XC1 and A2XC1XB3, when the simulation duration is 9 units, the operation conditions of the two simulation operation time axes are the same, but the order is different. At this time, the two simulation operation time axes are uniformly updated to A2XB3XC1 for subsequent analysis. The position of A2 does not change because the original operation type exists.

[0116] Step S501 : defining the last subsequent operation type in each updated simulation operation timeline as a finishing operation type, and defining the simulation duration corresponding to the finishing operation type as a finishing duration.

[0117] Define the type of closing operation and the closing duration to distinguish different data for subsequent analysis.

[0118] Step S502: Determine whether the ending duration is shorter than a preset reference duration.

[0119] The benchmark duration is the minimum finishing time set by the staff to ensure that the mold can be effectively operated after replacement. The purpose of the judgment is to know whether it is necessary to replace the last mold at present, so as to reduce the situation where the mold is replaced for a long time and then only operated for a short time.

[0120] Step S5021: If there is no situation where the ending time is less than the preset reference time, the punching machine control operation is performed according to the currently updated simulation operation time axis.

[0121] When there is no situation where the ending time is less than the preset reference time, it means that the last mold on each punching machine can operate well after being replaced. At this time, the punching machine operation can be controlled normally according to the updated simulation operation time axis.

[0122] Step S5022: If the closing duration is less than the preset reference duration, the corresponding closing operation type is defined as an abnormal operation type, and the corresponding closing duration is defined as an abnormal compensation duration.

[0123] When the finishing time is less than the preset benchmark time, it indicates that the mold was replaced for a long time and then only operated briefly, which requires further analysis. Define the abnormal operation type and abnormal compensation time to distinguish different data for subsequent analysis.

[0124] Step S503: Define the simulated operation time axis corresponding to the punch press whose finishing operation type is consistent with the abnormal operation type as an alternative compensation time axis, select a unique compensation time axis from the alternative compensation time axes, update the compensation time axis in the compensation time axis according to the abnormal compensation duration, and perform the punch press control operation according to the updated compensation time axis.

[0125] An alternative compensation time axis is defined to distinguish the punch presses that can process the stamping parts required by the punch press corresponding to the current abnormal operation type, so as to update the abnormal compensation time by selecting a unique compensation time axis from the alternative compensation time axis, so that the molds on some punch presses do not need to be replaced so that the remaining punch presses with existing molds of the same type can continue to operate, thereby reducing the situation where the mold is replaced for a long time and then only operated for a short time; the updating method of the compensation time axis is to extend the abnormal compensation time at the end of the compensation time axis.

[0126] The steps of selecting a unique compensation time axis from among the alternative compensation time axes include:

[0127] Step S600: constructing a history interval on a preset time axis with the current time point as the end point and a width of a preset historical duration.

[0128] The time axis is a coordinate axis formed by the combination of various time points. The coordinate axis points from the time points that have passed to the time points that have not yet arrived. The time points that have passed are on the left side of the time axis, and the left side of the time axis is defined as the front of the time axis. The historical duration is the duration from the press being put into use to the current time point. By constructing a historical interval, it is convenient to obtain and analyze data within the historical duration.

[0129] Step S601: determining the overall operation duration of the current abnormal operation type according to the punch press corresponding to the candidate compensation time axis in the historical interval.

[0130] The overall operation time is the total time that the punch press takes to produce the stamping parts of the abnormal operation type.

[0131] Step S602: determining the overall operation duration with the smallest value according to the sorting rule, and determining the alternative compensation time axis of the punch press corresponding to the overall operation duration as the used compensation time axis.

[0132] The sorting rules can be used to determine the overall operation time with the minimum value, that is, at this time, the corresponding mold on the punch press has the least wear due to production, which is more conducive to the production of this type of stamping parts. At this time, the corresponding alternative compensation time axis can be determined as the compensation time axis to be used.
