[0061] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0062] The method for determining the amount of lubricant applied provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, terminal 102 communicates with the server via a network. A data storage system can store the data that the server needs to process. The data storage system can be integrated on the server, or it can be placed in the cloud or on other network servers. The method for determining the amount of lubricant applied provided in this application embodiment can be executed by terminal 102 or the server alone, or by terminal 102 and the server working together. Taking execution by terminal 102 alone as an example: multiple types of lubricants 104 are respectively coated on the first surface of their corresponding stamping templates 106; the punch 108 is controlled to stamp the first surface of the stamping templates 106 corresponding to each lubricant 104, obtaining the bulging stroke corresponding to each lubricant 104; based on the bulging stroke corresponding to each lubricant 104 and the reference bulging stroke corresponding to a reference lubricant, a target lubricant is determined from the multiple types of lubricants 104 and the reference lubricant; based on the bulging stroke of the target lubricant under multiple application amounts, the target application amount of the target lubricant under the target bulging stroke is determined. The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle systems. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices. The server can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0063] In one embodiment, such as Figure 2 As shown, a method for determining the amount of lubricant applied is provided, which can be applied to computer equipment (the computer equipment can be...). Figure 1 Taking terminal 102 or server as an example, the following steps are included:

[0064] S202, applying various types of lubricants to the first surface of their respective corresponding stamping templates.

[0065] Lubricants are lubricating media used to reduce frictional resistance and slow down wear. Common types of lubricants include mineral lubricants, vegetable lubricants, animal lubricants, and synthetic lubricants. Lubricants come in various forms, including oily liquids such as lubricating oils, greases, and solid lubricants. The stamping template can be a metal sheet, for example, a steel sheet.

[0066] The method of applying lubricant to the die to be stamped can be to use computer equipment to control the application plate or brush to apply the lubricant to the die.

[0067] The first surface refers to one of the surfaces of the template to be stamped. The shape of the template can be square, round, rectangular, or any other arbitrary shape. Lubricant is applied to the first surface of the template, while the other surface is not coated with lubricant. This facilitates lubrication during stamping and allows for better simulation of stamping characteristics as needed.

[0068] In some embodiments, each type of lubricant is applied to the first surface of its respective stamping template; in other embodiments, multiple types of lubricants are applied to different locations on the first surface of a stamping template.

[0069] S204 controls the punch to press the first surface of the stamping template corresponding to each lubricant, thereby obtaining the bulging stroke corresponding to each lubricant.

[0070] In stamping dies, the punch is a part used to form the inner surface of the product; that is, a part whose working surface is its external shape. Stamping dies are special process equipment used in cold stamping to process a template into parts or semi-finished products. The punch is the most common component in stamping dies. The bulging stroke refers to the distance the punch travels.

[0071] Computer equipment controls the punch to punch the first surface of the stamping template corresponding to each lubricant, thereby obtaining the punch's bulging stroke when the stamping template is coated with each lubricant.

[0072] S206, determine the target lubricant from multiple types of lubricants and the reference lubricant based on the bulging stroke corresponding to each lubricant and the reference bulging stroke corresponding to the reference lubricant.

[0073] The reference lubricant is a lubricant with known lubrication properties. The reference bulging stroke refers to the bulging stroke of the punch when the template to be stamped is coated with the reference lubricant and stamped.

[0074] The bulging stroke may differ for each type of lubricant. The computer equipment determines the target lubricant from multiple types of lubricants and a reference lubricant based on the bulging stroke corresponding to each lubricant and a reference bulging stroke corresponding to a reference lubricant.

[0075] The target lubricant refers to the lubricant with the best lubrication performance among various types of lubricants and reference lubricants when stamping the sample to be stamped.

[0076] S208, based on the expansion stroke of the target lubricant under various oil application amounts, determine the target oil application amount of the target lubricant under the target expansion stroke.

[0077] Here, "oil application amount" refers to the amount of target lubricant applied to the template to be stamped. Computer equipment controls the punch to perform stamping under various oil application amounts, resulting in bulging strokes for different oil application amounts.

[0078] The target bulging stroke refers to the preset bulging stroke. The computer equipment determines the target amount of lubricant at the target bulging stroke from a variety of lubrication amounts. The appropriate amount of lubrication is beneficial for stamping.

[0079] In the above method for determining the amount of lubricant applied, multiple types of lubricants are applied to the first surface of their respective stamping templates. The punch is then controlled to press the first surface of the stamping template corresponding to each lubricant, obtaining the bulging stroke corresponding to each lubricant. Based on the bulging stroke corresponding to each lubricant and the reference bulging stroke corresponding to a reference lubricant, the target lubricant is determined from multiple types of lubricants and the reference lubricant. This method of applying lubricant to the first surface of the stamping template is beneficial for better simulating the punching characteristics. By comparing the bulging strokes corresponding to multiple types of lubricants and the reference lubricant, the target lubricant with the best lubrication performance can be determined. The target amount of the target lubricant determined based on the bulging stroke of the target lubricant under multiple application amounts has high accuracy.

[0080] In one embodiment, such as Figure 3 As shown, the stamping template also includes a second surface; controlling the punch to stamp the first surface of the stamping template corresponding to each lubricant to obtain the bulging stroke corresponding to each lubricant includes:

[0081] S302, for each type of lubricant, fix the stamping template corresponding to the current lubricant onto the pressure ring.

[0082] The blank holder is a component in a stamping die. It's a clamping device designed to prevent wrinkling of the die during the deep drawing process. Using the blank holder for variable blank holder control significantly reduces costs and offers high practicality. For each type of lubricant, computer equipment controls the corresponding die to be fixed onto the blank holder.

[0083] S304, control the punch to punch the first surface of the stamping template corresponding to the current lubricant, so that the second surface of the stamping template is close to the die, until the stamping template cracks, and obtain the punch stroke corresponding to the current lubricant.

[0084] The template to be stamped includes a first surface and a second surface. The second surface is not coated with lubricant. The die is a cavity mold used to shape the outer surface of the template to be stamped. The stamping die includes a punch, a die, and a blank holder.

[0085] The computer-controlled punch presses the first surface of the template corresponding to the current lubricant. After the blank holder and die close, the template is pressed tightly. The computer-controlled punch applies a blank holder force, the magnitude of which should ensure that the template does not wrinkle. The punch is controlled to move forward, gradually contacting the first surface of the template. After contacting the first surface, the punch continues to move forward, bringing the second surface of the template closer to the die, until the template cracks. The computer-controlled punch acquires the distance traveled from contacting the first surface until the template cracks, and uses this distance as the punch stroke corresponding to the current lubricant.

[0086] S306 defines the punch stroke corresponding to each lubricant as its corresponding bulging stroke.

[0087] In this system, the computer equipment uses the punch stroke corresponding to each type of lubricant as its corresponding bulging stroke. Multiple types of lubricants are processed using this method to determine their respective bulging strokes. The bulging stroke is used to indicate the lubricating performance of the corresponding lubricant.

[0088] In this embodiment, for each type of lubricant, the corresponding stamping template is fixed on the blank holder. The punch is controlled to stamp the first surface, while the second surface approaches the die, until the stamping template cracks. This yields the bulging stroke corresponding to each lubricant. The first surface of the stamping template contacts the punch; during stamping, only the first surface contacts the punch. Due to the friction generated during stamping, the lubricant provides lubrication. The magnitude of this lubrication effect is an evaluation index reflecting the lubricating performance of the lubricant, which helps to more accurately determine the amount of lubricant applied.

[0089] In one embodiment, applying multiple types of lubricants to the first surface of their respective corresponding stamping templates includes: obtaining the radius of the punch for each lubricant; determining the coating area based on the radius of the punch; and applying the current lubricant to the first surface of the corresponding stamping template based on the coating area.

[0090] In this embodiment, the radius of the punch is the radius of its cross-section. In some embodiments, the punch has a circular cross-section, or it may be a hemisphere. The computer device obtains the radius of the punch's cross-section and multiplies the square of this radius by π, using the result as the coating area. In other embodiments, the punch has a rectangular cross-section, or it may be a cuboid. The computer device obtains the length and width of the punch's cross-section and determines the coating area based on this information. The coating area is equal to the product of the length and width of the punch's cross-section. Multiple types of lubricants can be stamped using the same size punch or different punches. When multiple types of lubricants use different punches, the computer device obtains the radius of the punch corresponding to each lubricant.

[0091] The coating area is the area of ​​lubricant applied to the first surface of the stamping template. The computer equipment determines the coating position on the stamping template corresponding to the current lubricant, with the center of the coating position being the center of the stamping template. The area of ​​the coating position is equal to the area of ​​the coating region. The computer equipment controls an oiling plate or brush to apply the current lubricant to the corresponding coating position on the first surface of the stamping template. Multiple types of lubricants are applied to their respective coating positions on the first surface of the stamping template.

[0092] In this embodiment, by determining the coating area based on the punch radius for each lubricant, stamping is performed within the area of ​​the coating area, which helps to obtain an accurate amount of oil. The coating area allows for the determination of the coating position on the stamping template. The coating position can only be on the side in contact with the punch, and it cannot be applied to the entire first surface of the template; instead, it should be applied to the interior of the first surface, with a size equal to the coating area determined by the punch radius. This coating position facilitates accurate evaluation of the lubricating properties of the lubricant, improving the accuracy of the oil application. Since the coating position is in direct contact with the punch, using an appropriate amount of oil with good lubricating properties during the stamping process is beneficial for stamping.

[0093] In one embodiment, such as Figure 4 As shown, based on the bulging stroke corresponding to each lubricant and the reference bulging stroke corresponding to a reference lubricant, the target lubricant is determined from multiple types of lubricants and a reference lubricant, including:

[0094] S402 compares the bulging stroke corresponding to each lubricant with the reference bulging stroke corresponding to the reference lubricant.

[0095] The computer equipment compares the bulging stroke corresponding to each lubricant with the reference bulging stroke corresponding to a reference lubricant.

[0096] S404, in cases where the bulging stroke corresponding to all lubricants is greater than the reference bulging stroke, the reference lubricant shall be used as the target lubricant.

[0097] In cases where the bulging stroke for all types of lubricants across multiple categories is greater than the reference bulging stroke, it indicates that the lubrication performance of all types of lubricants is inferior to that of the reference lubricant. Computer equipment uses the reference lubricant as the target lubricant.

[0098] S406, if the bulging stroke corresponding to any lubricant is less than or equal to the reference bulging stroke, the corresponding lubricant is selected as a candidate lubricant; based on the bulging stroke corresponding to the candidate lubricant, the target lubricant is determined.

[0099] In this process, if the bulging stroke corresponding to any lubricant is less than or equal to the reference bulging stroke corresponding to a reference lubricant, it indicates that the lubricating performance of that lubricant is superior to that of the reference lubricant, and the computer device designates this type of lubricant as a candidate lubricant. The candidate lubricant's lubricating performance is superior to that of the reference lubricant. Based on the bulging stroke corresponding to the candidate lubricant, the computer device determines the target lubricant. Specifically, the candidate lubricants include at least one type of lubricant. If the candidate lubricants include multiple types, the computer device designates the candidate lubricant with the smallest bulging stroke among the multiple candidate lubricants as the target lubricant. If there is only one type of candidate lubricant, the computer device designates that candidate lubricant as the target lubricant.

[0100] In this embodiment, by comparing the bulging stroke corresponding to each type of lubricant with a reference bulging stroke, the reference lubricant is selected as the target lubricant when the bulging stroke of all lubricants is greater than the reference bulging stroke. If the bulging stroke of any lubricant is less than or equal to the reference bulging stroke, the target lubricant is determined based on the bulging stroke of the candidate lubricants. This method of determining the target lubricant ensures that the bulging stroke corresponding to the target lubricant is the smallest among various types of lubricants and the reference lubricant, thus identifying the target lubricant with the best lubrication performance and facilitating accurate application of the target lubricant.

[0101] In one embodiment, such as Figure 5 As shown, the target lubricant amount at the target expansion stroke is determined based on the expansion stroke of the target lubricant under various lubrication amounts, including:

[0102] S502, applying various amounts of target lubricant to the first surface of their respective stamping templates.

[0103] In this process, when applying multiple types of lubricants to the first surfaces of their respective stamping templates, the amount of each type of lubricant applied is equal. After determining the target lubricant with the best lubrication performance, the computer device further determines the precise amount of the target lubricant applied. The computer device controls an oiling plate or brush to apply the target lubricant in multiple amounts to the first surfaces of their respective stamping templates. In some embodiments, each amount of target lubricant corresponds to one stamping template; in other embodiments, multiple amounts of target lubricant are applied to different locations on the same first surface of the stamping template. In some embodiments, the computer device determines the coating area based on the radius of the punch, and applies the target lubricant in multiple amounts to the first surfaces of their respective stamping templates based on the coating area.

[0104] S504 controls the punch to press the first surface of the stamping template corresponding to various oil application amounts, thereby obtaining the expansion stroke of the target lubricant under various oil application amounts.

[0105] In this process, a computer-controlled punch presses the first surface of a stamping template corresponding to various oil application amounts, obtaining the bulging stroke of the target lubricant under different oil application amounts. Specifically, for each oil application amount, the computer-controlled punch fixes the stamping template corresponding to the current oil application amount onto the blank holder, and controls the punch to press the first surface of the stamping template corresponding to various oil application amounts, so that the second surface of the corresponding stamping template approaches the die, until the corresponding stamping template cracks, obtaining the punch stroke corresponding to the current oil application amount, and using the punch stroke corresponding to each oil application amount as its respective bulging stroke.

[0106] S506, based on the expansion stroke of the target lubricant under various oil application amounts, determine the target oil application amount of the target lubricant at the target expansion stroke.

[0107] The target bulging stroke is the target stroke of the punch when stamping a new blank to be stamped. The computer equipment fits bulging stroke curves for different lubricant application amounts based on the bulging stroke of the target lubricant at various application amounts. When evaluating the application amount of the target lubricant to the new blank to be stamped, the application amount corresponding to the target bulging stroke is determined based on the bulging stroke curve, and this application amount is taken as the target application amount of the target lubricant at the target bulging stroke.

[0108] In this embodiment, by applying target lubricants of various application amounts to the first surface of their respective corresponding stamping templates, and controlling the punch to stamp the first surfaces of the templates corresponding to the various application amounts, the bulging strokes under various application amounts are obtained, thereby determining the target application amount under the target bulging stroke. This is beneficial for determining the accurate target application amount of the target lubricant applied to the stamping template under different target bulging strokes.

[0109] In one embodiment, applying multiple amounts of target lubricant to the first surface of their respective corresponding stamping templates includes: determining multiple masses of target lubricant; for each mass, determining the current amount of lubricant based on the coating area and the current mass; and applying the multiple amounts of target lubricant to the first surface of their respective corresponding stamping templates.

[0110] Here, the amount of lubricant applied refers to the mass of lubricant applied per unit area. The mass of lubricant applied is easier to determine than the amount of lubricant applied. The computer equipment determines multiple different amounts of lubricant based on the different masses of lubricant. The computer equipment first determines multiple target masses of lubricant. For each mass, the computer equipment divides the current mass by the coating area to obtain the current amount of lubricant applied. Given the same coating area, multiple masses correspond to multiple amounts of lubricant. The computer equipment controls an oiling plate or brush to apply the target lubricant of various amounts to the first surface of the corresponding stamping template.

[0111] In this embodiment, multiple oil application amounts are determined by using target lubricants of various qualities. The quality of the applied lubricant is easier to determine than the direct oil application amount, which helps to improve the accuracy of the oil application amount.

[0112] To illustrate in detail the method for determining the amount of lubricant applied and its effect in this solution, a detailed embodiment is provided below, in which the stamping die includes a punch, a die, and a blank holder:

[0113] The computer equipment applies various types of lubricants to the first surface of their respective corresponding stamping templates; the stamping templates include a first surface and a second surface. Specifically, for each lubricant, the radius of the punch is obtained, the coating area is determined based on the punch radius, and the current lubricant is applied to the corresponding first surface of the stamping template based on the coating area. For example, the stamping template is a square template, which, after stamping, becomes a hemispherical shape. The punch and die are forming stamping dies used to shape the required stamping template so that the stamping template ultimately presents the desired shape. Figure 6 The diagram shows a sample plate to be stamped coated with lubricant.

[0114] The bulging cracking of the stamping template during the stamping process is caused by cracking to occur after stamping to a certain extent. The bulging cracking stroke will vary depending on whether lubricant is applied, the weight of different lubricants, or different types of lubricants. The bulging stroke refers to the distance the punch travels from the moment the punch makes contact with the first surface of the stamping template until the template cracks. The computer equipment, for each lubricant, fixes the stamping template corresponding to that lubricant on the blank holder and controls the punch to press the first surface of the stamping template corresponding to that lubricant, so that the second surface of the corresponding stamping template approaches the die, until the corresponding stamping template cracks. This obtains the punch stroke corresponding to the current lubricant, and the punch stroke corresponding to each lubricant is taken as the corresponding bulging stroke. For example... Figure 7 The diagram illustrates the cracking of a stamping template after stamping. Computer-controlled equipment directs the punch to contact the first surface of the template, which is coated with lubricant, while the second surface, in contact with the die, is uncoated. The computer-controlled equipment applies a blank holder force to the template, the magnitude of which is optimal to prevent wrinkling during the stamping process. Different blank holder forces affect the bulging stroke; for templates made of the same material, the blank holder force is a fixed value.

[0115] The computer equipment determines the target lubricant from multiple types of lubricants and a reference lubricant based on the bulging stroke corresponding to each lubricant and a reference bulging stroke corresponding to a reference lubricant. Specifically, the bulging stroke corresponding to each lubricant is compared with the reference bulging stroke corresponding to the reference lubricant. If the bulging stroke of all lubricants is greater than the reference bulging stroke, the reference lubricant is selected as the target lubricant. If the bulging stroke of any lubricant is less than or equal to the reference bulging stroke, the corresponding lubricant is selected as a candidate lubricant. The target lubricant is then determined based on the bulging stroke of the candidate lubricants. Figure 8The diagram shows various types of lubricants and their corresponding bulging strokes. The horizontal axis represents the type of lubricant, and the vertical axis represents the bulging stroke. A, B, D, E, and F represent different types of lubricants, and C represents the reference lubricant. The bulging stroke of reference lubricant C is 156 mm, while that of lubricant A is 157.3 mm, a difference of 1.3 mm. Therefore, the rating score for lubricant A is 100 + 1.3 = 101.3, indicating that the lubrication characteristics of reference lubricant C are superior to those of lubricant A. The bulging stroke of lubricant B is 155.6 mm, a difference of -0.4, resulting in a rating score of 100 + (-0.4) = 99.6. Therefore, the lubrication characteristics of reference lubricant C are inferior to those of lubricant B. Thus, the order of lubrication characteristics can be determined as B > C > A. The better the lubricating properties of the lubricant, the more fully the material will pass through the stamping sample during the stamping process, and the faster the bulging area will thin. Once a certain thinning rate is reached, i.e., the bulging stroke reaches a certain distance, the stamping sample will crack. The smaller the bulging stroke, the better the lubricating performance of the lubricant, and the faster the stamping sample will crack.

[0116] The computer equipment determines the target lubricant application amount at the target expansion stroke based on the expansion stroke of the target lubricant at various application amounts. Specifically, the target lubricant at various application amounts is applied to the first surface of the corresponding stamping template, and the punch is controlled to stamp the first surface of the stamping template corresponding to the various application amounts to obtain the expansion stroke of the target lubricant at the various application amounts. Based on the expansion stroke of the target lubricant at the various application amounts, the target lubricant application amount at the target expansion stroke is determined. For example... Figure 9 The diagram shows a fitting curve of oil application amount and bulging stroke. Based on the discrete point values ​​of various oil application amounts and bulging strokes of the target lubricant, a trend curve is fitted. When evaluating a new template, the appropriate oil application amount can be estimated based on the template's punching height to meet the requirements of the stamping process.
