Description

Technical Field

[0001] The present application relates to the field of atomizer core shell stamping, and in particular to a method, medium, and equipment for manufacturing an atomizer core shell. Background Art

[0002] The conventional turning process used in the atomizer core shell takes a long time to manufacture and wastes raw materials.

[0003] Some atomizer core shells use a stamping process, such as the prior art CN113680879B. However, when squeezing the boss of the atomizer core shell during the existing stamping process, it is easy for the stamping speed to be too fast, causing the material to flow rapidly in the mold, resulting in local excessive deformation. In addition, too fast a speed can easily result in excessive impact force, especially for thin-walled materials, which can easily cause cracking, tearing or surface damage.

[0004] However, if the stamping speed is too slow, each cycle will take too long in large-scale production, resulting in low overall production efficiency. Furthermore, too slow a stamping speed can lead to insufficient material flow, resulting in incomplete filling of the mold, especially for complex bosses or small structures. It can also cause the material to remain in the mold for too long, resulting in uneven springback during cooling.

[0005] Therefore, a method, medium and equipment for manufacturing an atomizer core shell that can accurately control the punching speed are needed. Summary of the Invention

[0006] In view of this, it is necessary to provide a method, medium and equipment for manufacturing an atomizer core shell with precise control of the stamping speed to solve the above problems.

[0007] An embodiment of the present application provides a method for manufacturing an atomizer core housing for thin-wall stamping of a cylinder, the method comprising the steps of:

[0008] S10: The mold stretches the plate to form a cylindrical structure;

[0009] S20: The upper mold drives the cylinder into the lower mold;

[0010] S30: The upper mold drives the cylinder into the lower mold forming groove, generates extrusion force and performs stamping, and the cylinder fills the lower mold forming groove, and the lower mold forming groove includes: an annular boss forming part and a rounded corner forming part connected to the annular boss and away from the cylinder;

[0011] S40: The upper die uses a first punching speed and generates a first extrusion pressure, so that the cylinder fills the annular boss forming portion and forms an annular boss integrally connected to the cylinder. The first punching speed increases the strength of the first extrusion pressure to reduce the forming time of the annular boss.

[0012] S50: Determine the forming time of the annular boss and then fill the fillet forming portion;

[0013] S60: The upper mold uses a second punching speed and generates a second extrusion pressure. The cylinder fills the rounded corner forming part and forms a rounded corner integrally connected to the annular boss. The second punching speed is 3 / 4 to 1 / 4 of the first punching speed. The filling time is extended to evenly fill the rounded corner forming part.

[0014] In at least one embodiment of the present application, the first punching speed is 1 / 2 of the second punching speed.

[0015] In at least one embodiment of the present application, the lower mold forming groove is provided with a heating wire, which generates heat to heat the lower mold forming groove to improve the ductility of the cylinder entering the lower mold forming groove and prevent the cylinder from breaking.

[0016] In at least one embodiment of the present application, the volume of the cylinder and the volume of the annular boss forming portion are obtained;

[0017] According to the volume ratio of the cylinder and the annular boss, the first reduced height of the cylinder is obtained;

[0018] The first reduction height of the cylinder is the second movement distance of the upper mold. After detecting the second movement distance of the upper mold, the extrusion of the annular boss is completed.

[0019] In at least one embodiment of the present application, after the annular boss is extruded, the fillet is extruded;

[0020] According to the volume of the cylinder and the set volume of the fillet, the second reduction height of the cylinder is obtained;

[0021] The second reduction height of the cylinder is the third movement distance of the upper mold. After detecting the third movement distance of the upper mold, the rounded corner extrusion is completed.

[0022] In at least one embodiment of the present application, a first movement distance of the upper mold driving cylinder into the lower mold is obtained;

[0023] The upper mold applies a constant speed to drive the cylinder into the lower mold;

[0024] According to the first moving distance and the constant speed, the first moving time is obtained, and the first moving time is recorded as T1.

[0025] In at least one embodiment of the present application, when the upper mold drives the cylinder into the forming groove of the lower mold, the upper mold supports the inner surface of the cylinder to limit the filling direction of the cylinder;

[0026] When the cylinder is located in the lower mold forming groove, the lower mold forming groove is annularly arranged on the outer surface of the cylinder.

[0027] In at least one embodiment of the present application, after the rounded corner stamping is completed, the upper and lower molds are closed and the heating wire of the lower mold forming groove is closed;

[0028] The gas is passed into the guide groove provided in the lower mold to cool the annular boss portion and the rounded corner forming portion;

[0029] After cooling, open the upper and lower molds;

[0030] Wherein, the guide groove is connected with the heating wire.

[0031] A computer-readable storage medium stores a computer program, which, when executed by a processor, causes the processor to perform the steps of any of the above methods.

[0032] A computer device comprises a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes the steps of any one of the above methods.

[0033] The beneficial effects of the above-mentioned method for manufacturing an atomizer core shell are as follows:

[0034] The stamping speed is adjusted in stages according to the filling state of the lower die forming groove and the flow of the material. The thin-walled material of the cylinder will be formed into two parts when it is squeezed into the lower die forming groove. The two parts are the annular boss and the rounded corner structure.

[0035] Moreover, in the closed-loop space of the mold, it is impossible to intuitively determine the flow of the thin-walled material from the cylinder into the lower mold forming groove. Therefore, it is necessary to calculate the volume of the lower mold forming groove and the change in volume height after the thin-walled material from the cylinder fills the lower mold forming groove to determine the filling state of the lower mold forming groove. After determining the filling state, the time point for switching the stamping speed is determined.

[0036] In order to ensure the rapid filling of the annular boss and to ensure that the details of the fillet can be evenly filled, the stamping speed is reduced and the stamping time is extended. A heating wire is wrapped around the lower mold forming groove to heat the material entering the lower mold forming groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] A method for manufacturing an atomizer core shell for thin-wall stamping of a cylinder, comprising the steps of:

[0049] The mold stretches the plate to form a cylindrical structure;

[0050] The upper mold drives the cylinder into the lower mold;

[0051] The upper mold drives the cylinder into the lower mold forming groove, generates extrusion force and performs stamping, and the cylinder fills the lower mold forming groove, and the lower mold forming groove includes: an annular boss forming part and a rounded corner forming part connected to the annular boss and away from the cylinder;

[0052] The upper die uses a first punching speed and generates a first extrusion pressure, the cylinder fills the annular boss forming portion and forms an annular boss integrally connected to the cylinder. The first punching speed increases the strength of the first extrusion pressure to reduce the forming time of the annular boss.

[0053] Determine the forming time of the annular boss and then fill the fillet forming part;

[0054] The upper mold uses a second punching speed and generates a second extrusion pressure. The cylinder fills the rounded corner forming part and forms a rounded corner integrally connected to the annular boss. The second punching speed is 3 / 4 to 1 / 4 of the first punching speed. The filling time is extended to evenly fill the rounded corner forming part.

[0055] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0056] See also Figure 1-Figure 7 The embodiment of the present application provides a method 100 for manufacturing an atomizer core housing, which is used for thin-wall stamping of a cylinder 210. The method comprises the following steps:

[0057] The mold stretches the plate to form a cylindrical body 210 structure.

[0058] The upper mold drives the cylinder 210 into the lower mold 400 .

[0059] The upper mold drives the cylinder 210 into the lower mold forming groove 410, generates extrusion force and performs stamping, and the cylinder 210 fills the lower mold forming groove 410. The lower mold forming groove 410 includes: an annular boss 220 forming part and a fillet 230 forming part connected to the annular boss 220 and away from the cylinder 210.

[0060] The upper mold uses a first punching speed and generates a first extrusion pressure. The cylinder 210 fills the annular boss 220 forming portion and forms an annular boss 220 integrally connected to the cylinder 210. The first punching speed increases the strength of the first extrusion pressure to reduce the forming time of the annular boss 220.

[0061] The molding time of the annular boss 220 is determined, and then the fillet 230 molding portion is filled.

[0062] The upper die uses a second punching speed and generates a second extrusion force, and the cylinder 210 fills the fillet 230 forming portion and forms the fillet 230 integrally connected to the annular boss 220. The second punching speed is 3 / 4 to 1 / 4 of the first punching speed, extending the filling time to evenly fill the fillet 230 forming portion.

[0063] Specifically, the upper die cooperates with the stretching die to complete the sheet metal stamping process in at least one pass, ensuring uniform sheet metal expansion and a uniform wall thickness. The flat sheet metal is transformed into a cylindrical structure 210, providing a basic form for subsequent stamping operations. This avoids the direct use of solid metal bar turning, thereby reducing raw material waste.

[0064] The upper mold is attached to and fixed on the inner surface of the cylinder 210 , and the upper mold drives the cylinder 210 into the lower mold 400 to punch the cylinder 210 , wherein the lower mold 400 is a punching mold.

[0065] The upper mold fits the inner surface of the cylinder 210, applying a supporting force to the cylinder 210, and during extrusion, since the upper mold fits the inner surface of the cylinder 210, deformation of the cylinder 210 will not occur on the inner surface of the cylinder 210, thereby limiting the deformation direction of the cylinder 210.

[0066] The servo motor provides driving force, and the upper mold moves downward, applying an axial pressure (P) to the cylinder 210.

[0067] Pressure P calculation:

[0068] P = F / A;

[0069] (Where F is the force applied by the upper mold and A is the contact area)

[0070] By adjusting the pressure value and speed of the servo press, the extrusion force can be precisely controlled.

[0071] Since the cylinder 210 is a thin-walled metal structure, the material will expand and flow outward under the pressure of the upper mold. This flow will be constrained by the lower mold forming groove 410, that is, the material will fill the space in the groove along the shape of the mold.

[0072] When the material enters the molding tank, it is blocked by the tank wall and its flow is restricted. The friction between the material molecules causes the extrusion pressure to increase further, so that the material fills the mold evenly.

[0073] To reduce the material's resistance to deformation and improve its fluidity, a heating wire is installed in the lower die forming groove 410. Its operating principle is as follows: the heating temperature is controlled between 100°C and 300°C. This heat is transferred to the metal material, improving its plasticity and reducing cracking caused by stress concentration during the stamping process. The heated metal softens, making it easier to fill the die under the extrusion pressure, while also reducing impact force.

[0074] Extrusion force F 挤压 :

[0075] F 挤压 =k×σ s ×A;

[0076] Where: k is the safety factor, the value is 1.1 to 1.5;

[0077] σ s is the yield strength of the material (unit: MPa)

[0078] A is the contact area (unit: mm)

[0079] The first punching speed provides sufficient extrusion force to quickly fill the annular boss 220 .

[0080] The second punching speed ensures uniform filling of the fillet area.

[0081] The punching speed also determines the size of the extrusion force, and the size of the extrusion force determines the forming speed of the material. Therefore, it is necessary to use a larger extrusion force in the first punching speed stage to quickly fill the annular boss forming portion 420.

[0082] The upper mold is driven by a servo press to ensure stable speed and precise position control.

[0083] Move downward at a constant speed to avoid damage to the cylinder due to excessive impact force.

[0084] In addition, by studying the effects of different settings of the second stamping speed on the stamping quality (filling time, defect rate) when the first stamping speed is fixed, the optimal ratio of the first stamping speed to the second stamping speed settings is determined.

[0085] Equipment and Materials

[0086] Material: 0.3mm stainless steel thin-walled cylinder

[0087] equipment:

[0088] Servo press (maximum punching force 100MPa)

[0089] Transparent upper and lower molds (temperature control range 100~300℃)

[0090] Pressure sensor (measures extrusion force)

[0091] High-speed camera (to observe material filling status)

[0092] Data acquisition system (recording punching speed, pressure, filling time, defect rate)

[0093] Experimental Table 1 (the first punching speed is fixed, and the second punching speed is variable):

[0094]

[0095]

[0096] Experimental Table 2 (fixed value of the second punching speed, the first punching speed is variable):

[0097]

[0098] From Experimental Table 1 and Experimental Table 2, it can be concluded that when the speed ratio (second punching speed / first punching speed) is greater than 3 / 4 and the first punching speed is a fixed value, the second punching speed punches the rounded corners, and the filling time of the rounded corners is short. The filling time of the rounded corners is short, and it is easy for the material to be quickly filled in the rounded corner forming part, resulting in uneven filling and a high defect rate.

[0099] When the second punching speed is a fixed value, the first punching speed punches the annular boss, and the filling time of the annular boss is too long. The second punching speed is too slow, which will also make the material flow speed insufficient, resulting in incomplete filling of the material in the annular boss part, resulting in a high defect rate.

[0100] When the speed ratio (second punching speed / first punching speed) is less than 1 / 4 and the first punching speed is a fixed value, the second punching speed is used to punch the rounded corners. The filling time of the rounded corners is too long. If the second punching speed is too slow, the material flow rate will be insufficient, resulting in incomplete filling of the material in the rounded corner forming part, resulting in a high defect rate.

[0101] When the second punching speed is a fixed value, the annular boss is punched at the first punching speed, and the filling time of the annular boss is short, resulting in local excessive deformation. Moreover, if the speed is too fast, the impact force is too large, which may cause rupture of the cylinder. Therefore, the defect rate is high.

[0102] The speed ratio (second punching speed / first punching speed) is 3 / 4 to 1 / 4, and the defect rate is similar. And when the speed ratio (second punching speed / first punching speed) is 1 / 2, both the punching time and the punching strength are guaranteed, and the defect rate is the lowest.

[0103] In a specific embodiment, the lower mold forming groove 410 is provided with a heating wire 440, which generates heat to heat the lower mold forming groove 410 to improve the ductility of the cylinder 210 entering the lower mold forming groove 410 and prevent the cylinder 210 from breaking.

[0104] Specifically, heating wires 440 are installed at appropriate positions of the lower mold forming groove 410. These heating wires 440 are connected to a power source and can generate heat in a controlled manner.

[0105] By controlling the power supply, the heating wire 440 starts to generate heat, and the heat is transferred to the lower mold forming groove 410 to increase its temperature.

[0106] Because the lower mold forming groove 410 is heated, when the cylinder 210 is driven into the groove by the upper mold, the cylinder 210 material has better ductility at a higher temperature. Improved ductility helps the cylinder 210 fill the lower mold forming groove 410 more smoothly and reduces the risk of cracking caused by excessive hardness of the material.

[0107] In one embodiment, the volume of the cylindrical body 210 and the volume of the formed portion of the annular boss 220 are obtained. Based on the volume ratio of the cylindrical body 210 to the annular boss 220, the first reduced height of the cylindrical body 210 and the first reduced height of the cylindrical body 210 are obtained. The forming time of the annular boss 220 is calculated based on the first reduced height, the first extrusion force, and the first punching speed.

[0108] Specifically, the methods for obtaining the volume of the cylinder 210 and the volume of the forming portion of the annular boss 220 include: a drainage method (or a replacement method), a gas expansion method, and a volume calculation method.

[0109] The plate is stretched into a cylinder. The dimensions of the cylinder are also known. The annular boss is formed according to the needs. The dimensions of the annular boss are known. According to the inner radius r1, outer radius r2, and height h1 of the cylinder, the volume V1 of the cylinder is:

[0110] V1=πr2 2 h1-πr1 2 h1;

[0111] The annular boss is connected to the outer surface of the cylinder. The inner radius of the annular boss is equal to the outer radius r2 of the cylinder. The outer radius r3 of the annular boss is the height h2 of the annular boss. The volume V2 of the annular boss is:

[0112] V1=πr3 2 h2-πr2 2 h2;

[0113] After the first stamping and extrusion, the material of the cylinder will flow into the annular boss forming groove. According to the volume of the cylinder and the volume of the annular boss forming part, the height of the cylinder material reduced after flowing into the annular boss forming part can be obtained. The reduced height is the first reduction height h 缩小 ;

[0114] h 缩小 =h1-(r3 2 -r2 2 )×h2) / (r2 2 -r1 2 );

[0115] When the extruded cylinder 210 enters the forming portion of the annular boss 220 , the upper mold drives the cylinder 210 to move. During the mold manufacturing process, the moving distance of the upper mold is set according to the first shrinking height of the cylinder 210 .

[0116] This is achieved through the control system of mold manufacturing equipment (such as injection molding machines, punching machines, etc.), which controls the movement distance of the upper mold to ensure the correct molding of the annular boss 220, improve production efficiency and product quality, and reduce scrap rate.

[0117] Methods for monitoring the upper mold's travel distance primarily include using precision measuring equipment such as mechanical displacement sensors, laser rangefinders, magnetic scales, or linear scales, as well as providing position feedback and monitoring through the mold manufacturing equipment's built-in control system. The upper mold's travel distance is monitored in real time. When the travel distance reaches a preset value (the first reduction height), the annular boss 220 is extruded.

[0118] In one embodiment, after the annular boss 220 is extruded, the fillet 230 is extruded. The second reduction height of the cylinder 210 is determined based on the volume of the cylinder 210 and the set volume of the fillet 230. The second reduction height of the cylinder 210 is the third movement distance of the upper mold. When the third movement distance of the upper mold is detected, the extrusion of the fillet 230 is completed.

[0119] After the annular boss 220 is extruded, the cylinder 210 begins to be extruded into the fillet 230. The extruded cylinder 210 then enters the fillet 230 from the annular boss 220.

[0120] The volume of the fillet 230 is obtained by the drainage method (or replacement method), the gas expansion method and the volume calculation method, and the second shrinkage height of the cylinder is calculated using the cylinder volume V1 obtained in the previous step.

[0121] Based on the previously calculated second reduction height, the upper die determines the distance it needs to move, known as the third movement distance. The upper die then moves this distance at the second stamping speed while continuously applying the second extrusion force until the fillet 230 is completely filled and integrally connected to the annular boss 220. During this process, the upper die's movement distance is monitored in real time to ensure it reaches the desired position, completing the extrusion of the fillet 230.

[0122] Methods for monitoring the upper mold's travel distance primarily include using precision measuring equipment such as mechanical displacement sensors, laser rangefinders, magnetic scales, or linear scales, as well as providing position feedback and monitoring through the mold manufacturing equipment's built-in control system. The upper mold's travel distance is monitored in real time. When the travel distance reaches a preset value (the second reduction height), the 230° fillet extrusion is complete.

[0123] In one embodiment, the first movement distance of the upper mold driving cylinder 210 into the lower mold 400 is obtained. The upper mold applies a constant speed to drive the cylinder 210 into the lower mold 400. Based on the first movement distance and the constant speed, the first movement time is obtained and recorded as T1.

[0124] Specifically, during the mold design phase, the size and shape of the barrel 210 and the size of the molding groove of the lower mold 400 are taken into consideration to determine the distance the upper mold needs to move, i.e., the first movement distance. This distance serves as the basis for controlling the speed and time of the subsequent upper mold movement.

[0125] After determining the initial movement distance, the upper mold will begin moving at a constant speed to drive the cylinder 210 into the lower mold 400. This constant speed is determined based on the properties of the material, the mold design, and the desired stamping effect. In actual operation, this constant speed can be achieved by adjusting the parameters of the drive system. The purpose of applying a constant speed is to ensure that the cylinder 210 can enter the lower mold forming groove 410 smoothly and evenly, avoiding material deformation or uneven filling due to speed changes.

[0126] The time required for the upper mold to complete its first movement, T1, is calculated using the first movement distance and constant speed. This calculation can be achieved using a simple physical formula: distance = speed × time. In practice, this time can be automatically calculated and monitored through programming or by setting a timer.

[0127] The first movement time T1 is a key parameter for controlling the subsequent stamping process. It helps us understand the speed and timing of the upper die entering the lower die 400, thereby better controlling the extrusion force and filling state during the stamping process. T1 also serves as a basis for subsequent adjustments to the stamping speed and extrusion force to ensure the quality and consistency of the final product.

[0128] In one embodiment, when the upper mold drives the cylinder 210 into the lower mold forming groove 410, the upper mold supports the inner surface of the cylinder 210 to limit the filling direction of the cylinder 210. When the cylinder 210 is located in the lower mold forming groove 410, the lower mold forming groove 410 is annularly arranged on the outer surface of the cylinder 210.

[0129] The upper mold ensures support for the inner surface of the cylinder 210 as it is driven into the lower mold's forming groove 410. This support is typically achieved through an adaptive shape within the upper mold, which matches the inner surface of the cylinder 210, providing a stable support force as the cylinder 210 is pushed into the lower mold 400. This support not only helps maintain the shape stability of the cylinder 210 but also effectively limits the deformation direction of the cylinder 210 during the filling process, ensuring that the material is filled along the predetermined path.

[0130] When the cylinder 210 is successfully pushed into the lower mold groove 410, the lower mold 400's groove is designed as an annular structure, tightly fitting the outer surface of the cylinder 210. This design ensures uniform external pressure on the cylinder 210 during the filling process, helping to evenly distribute the material between the inner and outer surfaces of the cylinder 210, forming a stable structure. The annular groove also takes into account the uniformity of material flow and filling efficiency.

[0131] The rounded corners 230 of the atomizer core housing 200 are stamped and formed. Subsequently, the upper and lower molds 400 are completely closed to ensure a tight seal within the molds. The heating wire 440 in the lower mold groove 410 is also closed. This not only provides a stable cooling environment for the subsequent cooling step, helping to control the cooling rate and uniformity, but also prevents material property changes or structural damage caused by continued heating during the cooling process.

[0132] In one embodiment, after the rounded corners 230 are stamped, the upper and lower molds 400 are closed and the heating wire 440 of the lower mold forming groove 410 is closed;

[0133] The gas is passed into the guide groove 450 provided in the lower mold 400 to cool the annular boss 220 and the fillet 230. After cooling, the upper and lower molds 400 are opened. The guide groove 450 is connected to the heating wire 440.

[0134] After the upper and lower molds 400 are closed and the heating wire 440 is turned off, cooling gas is introduced into the mold through the pre-set guide groove 450. The guide groove 450 is typically designed to directly connect to the annular boss 220 and the fillet 230, ensuring that the cooling gas can directly act on the lower mold groove 410. Parameters such as the type, flow rate, and temperature of the cooling gas need to be adjusted according to the specific material and molding requirements.

[0135] Directly introducing cooling gas lowers the temperature within the lower mold groove 410, as well as the annular boss 220 and fillet 230 within the lower mold groove 410. This helps form a stable microstructure and improves the mechanical properties of the product. The guide groove 450 avoids problems such as deformation or cracking caused by uneven cooling.

[0136] The connectivity between the guide groove 450 and the heating wire 440 ensures that when the cooling gas is introduced into the mold, it can exchange heat with the heat generated by the heating wire 440, thereby accelerating the cooling process. This design not only improves cooling efficiency but also helps maintain temperature uniformity within the mold.

By way of illustration and not limitation, RAM is available in many forms, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDRSDRAM), enhanced SDRAM (ESDRAM), synchronous link DRAM (SLDRAM), RAMbus direct RAM (RDRAM), direct RAMbus dynamic RAM (DRDRAM), and RAMbus dynamic RAM (RDRAM), etc.

[0140] Thus, the beneficial effects of the method 100 for manufacturing the atomizer core housing 200 are as follows:

[0141] The stamping speed is adjusted in stages according to the filling state of the lower die forming groove 410 and the flow of the material. The thin-walled material of the cylinder 210 is squeezed into the lower die forming groove 410 to form two parts, namely the annular boss 220 and the rounded corner 230.

[0142] Furthermore, in the closed-loop space of the mold, it is impossible to intuitively determine the flow of the thin-walled material of the cylinder 210 into the lower mold forming groove 410. Therefore, it is necessary to calculate the volume of the lower mold forming groove 410 and the change in volume height after the thin-walled material of the cylinder 210 fills the lower mold forming groove 410 to determine the filling state of the lower mold forming groove 410. After the filling state is determined, the time point for switching the stamping speed is determined;

[0143] In order to ensure that the annular boss 220 is quickly filled and the details of the fillet 230 are evenly filled, the stamping speed is reduced and the stamping time is extended. A heating wire 440 is wound around the groove of the lower mold 400 to heat the material entering the lower mold forming groove 410.

[0144] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
