Description

Technical Field

[0001] The invention relates to the technical field of tool stamping, in particular to a western pastry blade stamping forming system. Background Art

[0002] Bakery serrated knives are an indispensable tool in the baking process, mainly used for cutting various cakes and breads. The serrated design of this type of knife allows it to easily penetrate the outer crust of the food without crushing or damaging the soft tissue inside. For example, long serrated knives are suitable for cutting fluffy and soft cakes such as chiffon cakes, sponge cakes and butter cakes. The cutting principle is to create an initial puncture point through the tip of the serrations, and then perform a sawing action to ensure a smooth cut without breaking or damaging the edges; in addition to cakes, bakery serrated knives are also suitable for cutting bread. For example, a bread knife has long and wide serrations, designed to slice crusty bread without crushing the soft interior. In addition, fine serrated knives are suitable for cutting loose texture or smaller cakes, such as light cheesecakes.

[0003] When using a baking serrated knife, you need to pay attention to some skills. For example, when cutting a cake, you should wipe the blade clean before cutting the next one to ensure a clean cut surface. In addition, for some special cakes, such as heavy cheesecake and mousse cake, you can heat the knife on the fire first and cut it while it is hot, so as to avoid the cake sticking to the knife. Therefore, baking serrated knives are widely used in baking. Choosing the right knife and mastering the correct use method can greatly improve the beauty and quality of the baked works.

[0004] At present, when conventional pastry knives are produced, metal plates are often punched directly by a punching machine to obtain plates with the same shape as the pastry knives. Finally, the cutting edge of the plate is grinded and sharpened by a grinder to form serrations and blades. However, the current conventional operating methods have certain defects. The serrations at the serration position of the plate obtained by direct punching are large in size and cannot be arranged in small serrations. Therefore, if a pastry knife with small serrations is required, the serrations of the pastry knife need to be further polished and then reduced. Another method is to punch out a plate without serrations and then grind the cutting edge of the plate to form small serrations by subsequent separate grinding. However, no matter which method is used, additional processing is required to form small serrations.

[0005] However, if the large serrations are retained directly on the pastry knife, the large serrations will produce larger notches when cutting bread, cakes and other pastries, and more food residues will fall during the cutting process. Therefore, it is necessary to ensure that the serrations are as small as possible when the pastry blade is formed.

[0006] Therefore, a pastry blade stamping system is proposed to solve or alleviate the above problems. Summary of the invention

The input module 1 is coupled to the data processing module 2, and the output end of the data processing module 2 is coupled to the input end of the control module 3. The control module 3 is coupled to the laser pre-cutting module 4 and the stamping separation module 5. The input module 1 inputs the part model and basic parameters of the Western pastry blade and transmits them to the data processing module 2. The data processing module 2 optimizes and generates a hollow model according to the part model and basic parameters of the Western pastry blade and outputs it to the control module 3. The control module 3 controls the laser pre-cutting module 4 and the stamping separation module 5 to work in sequence according to the feedback content of the data processing module 2.

[0029] More specifically, the input module 1 includes a touch screen, which inputs the part model and basic parameters of the pastry blade and transmits them to the data processing module 2. The data processing module 2 includes a processor, which optimizes and generates a hollow model based on the part model and basic parameters of the pastry blade and outputs it to the control module 3. The control module 3 includes a controller, which controls the laser pre-cutting module 4 and the stamping separation module 5 to work in sequence based on the feedback content of the data processing module 2.

[0030] Preferably, if Figure 1 As shown, the laser pre-cutting module 4 includes a workbench 408, longitudinal slide rails 406 fixedly connected to both sides of the top surface of the workbench 408 in the feeding direction, limit seats fixedly connected to both ends of the longitudinal slide rails 406, longitudinal slide seats 405 slidably connected to the longitudinal slide rails 406, longitudinal screw rods 407 rotatably connected between the limit seats at both ends and threadedly connected to the longitudinal slide seats 405, transverse slide rails 401 fixedly connected between the longitudinal slide seats 405 on both sides, transverse slide seats 403 slidably connected to the transverse slide rails 401, and longitudinal slide seats 405 rotatably connected between the longitudinal slide seats 405 on both sides. The transverse lead screw 402 is threadedly connected to the transverse slide 403, and there is a gap between the transverse slide 401 and the top surface of the workbench 408. A laser is fixedly connected to the transverse slide 403. A first servo motor is fixedly connected to one of the limit seats, and the output shaft of the first servo motor is coaxially connected to one end of the longitudinal lead screw 407. A second servo motor is fixedly connected to one of the longitudinal slides 405, and the output shaft of the second servo motor is coaxially connected to one end of the transverse lead screw 402. The first servo motor, the second servo motor, and the laser are all coupled to the control module 3.

[0031] Preferably, if Figure 1 As shown, the stamping separation module 5 includes a base 501, a plurality of guide columns 502 fixedly connected to the top surface of the base 501 and vertically arranged, a top frame 503 fixedly connected to the top surface of the guide columns 502, a hydraulic cylinder 504 fixedly connected to the top frame 503, and a pressure plate 505 slidably connected to the guide columns 502, the pressure plate 505 is fixedly connected to the piston rod of the hydraulic cylinder 504, and the hydraulic cylinder 504 is coupled to the control module 3.

[0032] When the system processes the pastry blade, specifically before the metal sheet is processed into the pastry blade, it allows the part model and basic parameters of the pastry blade to be input in the input module 1, and determines through the data processing module 2 whether the blade can be processed into small serrations that meet the standards, thereby avoiding the risk of not being able to produce too small serrations. When it is confirmed that production is possible, the system will optimize the part model to ensure that all strength indicators meet the requirements, and design a suitable material-saving groove on the blade surface, thereby effectively reducing the amount of material used. This not only reduces the weight of the pastry blade, but also reduces production costs, and improves production efficiency by recycling the cut waste.

[0033] Then, when the data processing module 2 has completed the optimization of the part model of the pastry blade, the control module 3 can be used to control the laser pre-cutting module 4 to perform laser cutting on the metal sheet. The control module 3 drives the forward and reverse control of the first servo motor and the second servo motor, as well as the number of rotations, so that the laser can be moved to the corresponding position for laser cutting. The cut metal sheet can be pushed onto the base 501 of the stamping and separation module 5 together with the pastry blade, and then the control module 3 controls the hydraulic cylinder 504, so that the hydraulic cylinder 504 drives the pressure plate 505 to move downward, thereby completing a short stamping and knocking action on the metal sheet and the pastry blade, so that the pastry blade can fall off the metal sheet, and the excess material in the material saving slot of the pastry blade can also fall off, which is convenient for material separation.

[0034] The data processing module 2 generates a hollow model based on the part model and basic parameters of the pastry blade and outputs it to the control module 3, including the following steps: Determine the part model of the pastry blade and the basic parameters of the pastry blade, including size and material; Determine whether the input pastry blade is suitable for processing by the laser pre-cutting module 4. If so, proceed to the subsequent steps. If not, feed back to the input module 1 an unusable output result. The strength thresholds of the pastry blade are set, the part model of the pastry blade is optimized, and a material-saving groove is generated on the part model of the pastry blade to obtain a hollow model; The strengths are calculated according to the basic parameters of the hollow model and compared with the strength thresholds of the pastry blade. If they meet the requirements, the hollow model is output to the control module 3. If they do not meet the requirements, the previous steps are repeated.

[0035] Preferably, it is determined whether the input pastry blade is suitable for processing by the laser pre-cutting module 4. If it is suitable, the subsequent steps are entered. If it is not suitable, the input module 1 is fed back with an unusable output result, including the following steps: Get the dimensions of the pastry blade, including the tooth height h and the tooth base width , Sawtooth top width , Sawtooth Angle , and the spacing between adjacent teeth ; Analyze the width of the narrowest part of the sawtooth to determine whether this part can be achieved with the minimum aperture accuracy of the laser cutting machine. It can be obtained through geometric analysis that the two sides of the sawtooth form an acute angle The narrowest part appears at the intersection of two adjacent saw teeth. The narrowest spacing is calculated using trigonometric functions. ; Obtain the minimum cutting accuracy of the laser pre-cutting module 4 and determine the minimum cutting aperture of the laser pre-cutting module 4 ; According to the thermal expansion coefficient of the material of the pastry blade and the laser beam diameter of the laser pre-cutting module 4 Correct the thermal effects that may occur during laser cutting and calculate the changes caused by thermal effects , where t is the time the material is heated during the cutting process, and the corrected narrowest width is ; The judgment is made based on the final comparison of the corrected narrowest part width, the sawtooth top width and the spacing between adjacent sawtooth with the minimum cutting aperture of the laser pre-cutting module 4. If , the output result is applicable, otherwise the output result is not applicable.

[0036] According to the above method steps, through precise dimensional analysis and thermal effect correction, it is ensured that the laser pre-cutting module 4 can accurately cut the designed saw teeth, which not only improves the cutting accuracy, but also reduces the cutting error caused by thermal effects, thereby improving production efficiency and product quality.

[0037] Preferably, the strength thresholds of the pastry blade are set, the part model of the pastry blade is optimized, a material saving groove is generated on the part model of the pastry blade, and a hollow model is obtained, including the following steps: Obtain the part model of the pastry blade, and calculate the strength and rigidity of different areas of the pastry blade based on the basic parameters of the pastry blade; Set the objective function, which needs to reduce the material usage of the pastry blade and meet the minimum strength thresholds , where X is the design parameter of the material saving trough, , , , is the weight coefficient, is the volume of the pastry blade, is a quantity related to stiffness, usually the inverse of deformation, is the stress of each part of the pastry blade, is the damage accumulation function considering fatigue strength; Design a convolutional neural network model, take the geometry and material parameters of the pastry blade as a grid or image input, and extract the features of the input blade geometry and material distribution through multiple convolutional layers. After the convolution operation, the pooling layer will reduce the size of the image and extract important features. The extracted features are mapped to various indicators of the objective function through the fully connected layer. The gradient of the loss function with respect to the parameters of the economizer is calculated by the back-propagation algorithm:

[0038] in, is the gradient of the loss function with respect to the output, To output the gradient of the design parameters; The position, shape and area of ​​the material-saving slot are determined by optimizing the design parameters to obtain a hollow model.

[0039] In the above method steps, the use of the convolutional neural network model improves the efficiency and accuracy of model optimization. Through feature extraction and back propagation algorithms, the optimal design parameters can be quickly found to generate a hollow model that meets the strength and performance requirements. This not only improves production efficiency, but also ensures the quality and performance of the blade.

If it meets the requirements, the hollow model is output to the control module 3. If it does not meet the requirements, the previous steps are repeated, including the following steps: Determine the geometric parameters of the pastry blade in the hollow model, the geometric parameters of the pastry blade include blade length L, blade width W, blade thickness h, position of the material saving groove, depth of the material saving groove, and width of the material saving groove; Calculate the effective material volume of the pastry blade based on the geometric parameters and the specifications of the material saver , ,in, The volume of the material saving trough; Calculate flexural strength, shear strength, fatigue strength, rigidity, bending stress ,in, is the bending moment, which can be calculated from the external load and geometry, y is the distance from any point in the West Point blade to the neutral axis, and I is the moment of inertia of the blade section, which can be calculated using , shear stress ,in, is the shear force on the West Point blade, A is the effective cross-sectional area of ​​the West Point blade, and the fatigue limit ,in, is the material alternating stress of the pastry blade, N is the number of cycles, b is the fatigue index, and the rigidity of the pastry blade , where E is the Young's modulus of the material of the pastry blade, I is the moment of inertia of the blade cross section, and L is the blade length; The bending strength, shear strength, fatigue strength and rigidity are compared with each strength threshold. If they meet the requirements, the hollow model is output to the control module 3. If they do not meet the requirements, the previous steps are repeated.

[0041] According to the above method steps, through accurate geometric parameter calculation and strength accounting, it is ensured that the hollow model meets all strength and performance requirements during the design stage. This not only improves production efficiency, but also reduces production waste caused by improper design, ensuring the quality and performance of the final product.
