[0053] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0054] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a stamping machine that can improve production efficiency while reducing production costs.

[0055] The following is for reference. Figures 1-7 Describes a stamping apparatus 1 according to an embodiment of this application.

[0056] like Figure 1 As shown, the stamping equipment 1 includes: a first punch 10, a second punch 20, a mold assembly 30, an upper mold base 40, a slide block 50, and a drive mechanism 60.

[0057] The first punch 10 and the second punch 20 are the core components of the stamping equipment 1, responsible for transmitting pressure to the workpiece to achieve stamping. During the stamping process, the first punch 10 and the second punch 20 respectively penetrate the first punch 311 and the second punch 312 in the mold assembly 30, apply pressure to the workpiece during the stamping process, and complete different punching operations. In addition, the first punch 10 and the second punch 20 are distributed separately along the first direction X, and the first punch 10 or the second punch 20 can be automatically switched by control.

[0058] The die assembly 30 is the main die part of the stamping equipment 1 and has a punching function. The die assembly 30 is provided with a first punch 311 and a second punch 312 for the first punch 10 and the second punch 20 to pass through respectively. During the stamping process, the die assembly 30 is used to provide positioning and guidance for the workpiece, so that the punch can accurately punch.

[0059] The upper die holder 40 is the support part of the stamping equipment 1. It is usually used to receive the stamping force and transmit the stamping force to the first punch 10 or the second punch 20. The upper die holder 40 is equipped with a die shank, which can be connected to the mechanism that provides the stamping force through power coupling, thereby transmitting the stamping force to the upper die holder 40.

[0060] like Figure 2As shown, the slider 50 is a movable component connecting the upper die holder 40 and the first punch 10, as well as the upper die holder 40 and the second punch 20. It can move along the first direction X on the upper die holder 40. During the movement, the slider 50 can contact one of the first punch 10 or the second punch 20. The punching shapes of the first punch 10 and the second punch 20 are different. When the slider 50 contacts the first punch 10, the upper die holder 40 transmits the punching force to the first punch 10 through the slider 50, and the first punch 10 is used for punching. When the slider 50 contacts the second punch 20, the upper die holder 40 transmits the punching force to the second punch 20 through the slider 50, and the second punch 20 is used for punching. This allows a stamping equipment 1 to automatically switch between two different hole shapes for punching.

[0061] The slider 50 performs stamping operations by switching between punches of different hole types. The movement of the slider 50 is mainly achieved through cooperation with the drive mechanism 60. The drive mechanism 60 is poweredly coupled to the slider 50 and can drive the slider 50 to move along the first direction X. The drive mechanism 60 can be a motor, cylinder, or hydraulic cylinder, depending on the type and specifications of the stamping equipment 1. During stamping, the drive mechanism 60 controls different punches by driving the movement of the slider 50, thereby completing stamping operations of different hole types.

[0062] Some products on the market have different hole patterns on their surfaces, requiring the stamping of two different hole patterns. In related technologies, two sets of molds are usually used to perform the punching operation separately. However, the mold manufacturing cost is high, and frequent mold changes during the production process consume time, reduce production efficiency, and increase the complexity of operation and the risk of errors. There is room for improvement.

[0063] Based on the above considerations, in order to solve the problem of the many drawbacks of punching holes with multiple sets of molds, the inventors, after in-depth research, designed a stamping equipment 1.

[0064] According to the stamping equipment 1 provided in the embodiments of this application, by optimizing the die punching structure, a set of dies can be used to perform punching operations when punching different hole types, which helps to reduce production steps, improve production efficiency, and reduce production costs.

[0065] In some embodiments, such as Figure 3 As shown, the upper mold base 40 is provided with a slide groove 410, and the slider 50 is movably installed in the slide groove 410. The cross-section of the slider 50 includes a first section 510, a second section 520 and a third section 530 connected in sequence. The cross-sectional shape of the slide groove 410 is the same as that of the first section 510 and the second section 520.

[0066] The groove 410 is a channel in the upper die holder 40 used to guide the movement of the slider 50. The shape of the groove 410 matches the structure of the slider 50, so that the slider 50 can slide precisely and smoothly in the upper die holder 40 to prevent the slider 50 from tilting or deviating. This allows the punch to perform stamping operations accurately and smoothly. At the same time, the presence of the groove 410 can also help reduce friction and improve the movement efficiency and service life of the slider 50.

[0067] The cross-section of the slider 50 adopts an I-shaped structure, consisting of three parts: the first section 510, the second section 520, and the third section 530. The I-shaped structure helps to provide better strength and rigidity. The cross-sectional shape of the first section 510 and the second section 520 is the same as that of the groove 410, which allows the slider 50 to slide stably within the groove 410, reducing swaying or deviation during movement and stabilizing the movement trajectory of the slider 50. The third section 530 is used to contact the punch and bear the task of transmitting the punching force. At the same time, the I-shaped design is generally beneficial to disperse stress when subjected to external forces, thereby improving the load-bearing capacity and deformation resistance of the slider 50. In addition, there is a gap of about 0.5-1mm between the contact surface of the groove 410 and the slider 50, which can reduce deviation or instability during movement.

[0068] Understandably, through the design of the I-shaped cross section, the slider 50 can slide precisely in the groove 410 of the upper die holder 40, maintaining a stable motion trajectory. At the same time, the cooperation between the groove 410 and the slider 50 can provide the necessary stability and precision for the stamping equipment 1, reducing malfunctions or wear caused by friction and poor movement.

[0069] In some embodiments, such as Figure 4 As shown, the drive mechanism 60 includes a power source 610, a mounting plate 620 and a connector 630. The mounting plate 620 is provided with a fixing hole 621, and the power source 610 is connected to the connector 630 through the fixing hole 621.

[0070] The power source 610 drives the movement of the entire system by providing the necessary energy. It is usually an electric motor, cylinder, or hydraulic device, depending on the needs of the mechanical system. The mounting plate 620 is the basic structure for mounting and supporting the power source 610 and other mechanical components. It is usually a sturdy metal plate with fixing holes 621 for limiting the position, so that the components can be stably installed in the appropriate position. The mounting plate 620 can provide a solid support for the power source 610 and reduce the impact of vibration or displacement generated during movement on the stability of the system.

[0071] Meanwhile, the fixing hole 621 is an opening on the mounting plate 620, which allows the mounting plate 620 to be connected to other mechanical components more easily, improving the fitting accuracy between various parts. The connector 630 is a bridge connecting the power source 610 and other parts such as the slider 50. It uses a snap-fit ​​method to transmit the power transmitted by the power source 610 to the parts that need to be driven, so that the entire system moves along a predetermined path.

[0072] Understandably, the drive mechanism 60 achieves power transmission and coordinated movement of components through the combination of power source 610, mounting plate 620 and connector 630. At the same time, the design of fixing hole 621 on mounting plate 620 allows connector 630 to be stably connected to power source 610 and transmit power to the components that need to be driven.

[0073] In some embodiments, such as Figure 3 and Figure 4 As shown, the slider 50 is provided with a slot 540, and the connector 630 is provided with a boss 631, which engages with the slot 540.

[0074] The slot 540 is a groove or opening on the slider 50 designed to receive the boss 631 of the connector 630. Both the slot 540 and the boss 631 have a T-shaped cross-section. The slot 540 usually has a certain depth and width, which are greater than the depth and width of the boss 631. Specifically, there is a gap of about 0.5-1mm between the slot 540 and the boss 631 so that the boss 631 can be smoothly inserted and fixed therein, and reduce the displacement or instability that occurs during movement.

[0075] The slot 540 can effectively restrict the lateral or longitudinal movement of the connector 630, keeping the connector 630 in a predetermined position and relatively stationary with respect to the slider 50, reducing offset or instability during movement. At the same time, the slot 540 can also provide a stable mating position for the connector 630, making the power transmitted to the slider 50 through the connector 630 more stable and reducing losses caused by loose connection.

[0076] The boss 631 is a protruding part on the connector 630. Its size and shape match the slot 540 on the slider 50, allowing it to be precisely inserted into and locked in the slot 540, forming a secure connection. After the boss 631 enters the slot 540, the locking action firmly connects the connector 630 and the slider 50, reducing the risk of loosening between the slider 50 and the connector 630. In addition, the locking design simplifies the assembly process. Through the locking method of the boss 631 and the slot 540, fixing can be completed without additional fasteners, reducing assembly time and cost.

[0077] Understandably, the snap-fit ​​structure between the slot 540 and the boss 631 can strengthen the solid connection between the slider 50 and the connector 630, enhance the stability of the system, and at the same time, through this snap-fit ​​design, power can be smoothly and accurately transmitted to the slider 50, reducing the risk of inaccurate movement or low efficiency caused by loose or misaligned parts.

[0078] In some embodiments, such as Figure 1 As shown, the first punch 10 includes a first punch body 110 and a first positioning plate 120, and the second punch 20 includes a second punch body 210 and a second positioning plate 220. The first punch body 110 and the second punch body 210 are respectively used to penetrate the first punch hole 311 and the second punch hole 312, and the first positioning plate 120 and the second positioning plate 220 are used to contact the slider 50.

[0079] The first punch body 110 is typically a stamping tool with a specific shape, capable of forming precise holes in the workpiece. The first positioning plate 120 is used to contact the slider 50, and its function is to reduce the offset of the first punch body 110, improve its accuracy and stability, and ensure that the first punch body 110 is accurately positioned during the stamping process.

[0080] The second punch body 210 is used to penetrate the second punch hole 312. Its function is similar to that of the first punch body 110, but it corresponds to a punch hole of a different shape. The second positioning plate 220 is used to contact the slider 50 and also plays a positioning role, so that the second punch body 210 is kept in an accurate position during operation and the deviation is reduced.

[0081] In practical applications, the punch and the positioning plate work together to achieve a precise punching process. The positioning plate provides a stable contact surface to ensure accurate alignment of the punch body. During the punching process, the punch body moves along the punching hole and acts on the workpiece through the punching process to produce a precise hole.

[0082] Understandably, the first punch 10 and the second punch 20, through the precise positioning plate design, can improve the stability and accuracy of the punching operation. At the same time, by the contact between different positioning plates and the slider 50, the punches can be switched, thereby achieving punching of different shapes on the same component.

[0083] In some embodiments, such as Figure 1 and Figure 5 As shown, the stamping equipment 1 also includes a first reset mechanism 710 and a second reset mechanism 720. The first reset mechanism 710 is installed between the mold assembly 30 and the first positioning plate 120, and the second reset mechanism 720 is installed between the mold assembly 30 and the second positioning plate 220.

[0084] In the stamping equipment 1, the reset mechanism is usually used to enable the punch to return to its original position after each stamping operation so that the next stamping operation can be carried out. The reset mechanism mainly uses a certain force to enable the positioning plate to drive the punch body back to its original position after the stamping is completed, thereby improving the production efficiency of the equipment. At the same time, through reasonable reset force distribution, the risk of excessive wear or deformation of the punch and die assembly 30 is reduced.

[0085] The first reset mechanism 710 and the second reset mechanism 720 are respectively installed between the mold assembly 30 and the first positioning plate 120 and between the mold assembly 30 and the second positioning plate 220. When the first punch 10 is used for stamping, after the stamping action is completed, the first reset mechanism 710 will provide a reverse force to restore the first positioning plate 120 to its initial position. When the second punch 20 is used for stamping, after the stamping action is completed, the second reset mechanism 720 will also provide a reverse force to restore the second positioning plate 220 to its initial position.

[0086] The reset mechanism can restore the original position of the mold assembly 30 or the positioning plate in different ways. For example, the reset mechanism can be a nitrogen spring, a cylinder or other elastic element. During stamping, the punch and the mold assembly 30 are subjected to pressure and produce a small displacement. The reset mechanism provides a restoring force through the elastic element, so that the positioning plate returns to the predetermined position quickly and accurately.

[0087] Spring reset mechanisms primarily use the restoring force of compressed springs to reset the positioning plate. Pneumatic reset mechanisms mainly use cylinders to control changes in air pressure to achieve precise reset actions. Hydraulic reset mechanisms are similar to pneumatic reset mechanisms, providing restoring force through hydraulic control.

[0088] Understandably, the first reset mechanism 710 and the second reset mechanism 720 provide the necessary restoring force so that the positioning plate can quickly return to its initial position after each stamping action, thereby achieving accuracy and high efficiency in each stamping.

[0089] In some embodiments, such as Figure 5 and Figure 6 As shown, the mold assembly 30 is provided with a first mounting hole 313 and a second mounting hole 314. The first reset mechanism 710 is installed in the first mounting hole 313, and the second reset mechanism 720 is installed in the second mounting hole 314.

[0090] The mold assembly 30 is provided with a first mounting hole 313 and a second mounting hole 314. The first mounting hole 313 is used to install the first reset mechanism 710, and the second mounting hole 314 is used to install the second reset mechanism 720. The reset mechanism is located between the mold assembly 30 and the positioning plate and is installed in the corresponding mounting hole by interference fit. Its function is to enable the punch to quickly and accurately return to the initial position after completing the stamping operation. The first mounting hole 313 and the second mounting hole 314 are located on the side of the mold assembly 30 facing the positioning plate and correspond one-to-one with the first reset mechanism 710 and the second reset mechanism 720, respectively.

[0091] Specifically, the first reset mechanism 710 is installed in the first mounting hole 313 and abuts against the first positioning plate 120. The projection of the first positioning plate 120 on the mold assembly 30 in the vertical direction can cover the first mounting hole 313. Similarly, the second reset mechanism 720 is installed in the second mounting hole 314 and abuts against the second positioning plate 220. The projection of the second positioning plate 220 on the mold assembly 30 in the vertical direction can cover the second mounting hole 314.

[0092] Furthermore, the second reset mechanism 720 and the first reset mechanism 710 do not operate synchronously during the working process, but their working processes are basically the same, only the objects they act on are different.

[0093] Understandably, through the positioning and coordination between the mold assembly 30 and the reset mechanism, each component can quickly return to its original position after each stamping action, maintaining the accuracy of the stamping equipment 1 and improving stamping efficiency.

[0094] In some embodiments, such as Figure 1 and Figure 7 As shown, the mold assembly 30 includes a fixed plate 310 and a lower mold assembly 320. The lower mold assembly 320 is connected to the fixed plate 310 by fasteners. The fixed plate 310 is provided with a first punch 311 and a second punch 312.

[0095] The fixing plate 310 serves as a connecting bridge between the lower die assembly 320 and other components, providing both connection and support. The first punch 311 and the second punch 312 on the fixing plate 310 allow the first punch body 110 and the second punch body 210 to pass through, serving a positioning function. The first punch body 110 and the second punch body 210 pass through the first punch 311 and the second punch 312 to punch the lower die assembly 320 located below the fixing plate 310.

[0096] The lower die assembly 320 is part of the die assembly 30. It is responsible for direct contact with the workpiece or bearing the stamping operation. At the same time, the lower die assembly 320 is connected to the fixed plate 310 by fasteners, which can be easily disassembled and replaced when needed.

[0097] Fasteners are used to securely connect the fixed plate 310 and the lower mold assembly 320 together, so that the mold assembly 30 does not loosen or shift during operation, maintaining the accuracy of the parts and the molding quality. Fasteners can be bolts, nuts or screws, etc., and the strength of the connection is determined according to the actual working pressure and the mold material.

[0098] In addition, fasteners are subjected to repeated forces during the stamping process, and the edges of the punched holes may wear. Wear-resistant materials or surface treatments can be used to increase the durability of the punching holes. The lower die assembly 320 can reduce the risk of die deformation due to excessive weight by optimizing its weight and structure, thereby improving operational efficiency.

[0099] Understandably, the connection between the fixed plate 310 and the lower mold assembly 320 in the mold assembly 30 via fasteners can improve the stability and reliability of the mold assembly 30.

[0100] In some embodiments, such as Figure 7 As shown, the lower mold assembly 320 includes a cavity mold 330 and a lower mold base 340, with the cavity mold 330 installed between the fixed plate 310 and the lower mold base 340.

[0101] The die 330 is the part of the lower die assembly 320 that contacts the workpiece. It is responsible for supporting the workpiece during stamping. The die 330 can also be used to form the outer or internal shape of the workpiece. During the stamping process, the die 330 and the punch are used together. The die 330 provides the negative shape of the workpiece, and the punch applies pressure by cooperating with the die 330 to complete the forming of the material.

[0102] The lower die holder 340 is the supporting part of the entire lower die assembly 320. It is installed on the worktable of the punch press and connected to the mechanical system of the punch press. It can provide a stable platform to fix the die 330. The lower die holder 340 is fixedly connected to the fixing plate 310 by fasteners and forms a cavity. The die 330 is fixedly connected to the lower die holder 340 in the cavity. The function of the lower die holder 340 is to provide support and positioning for the die 330, and at the same time bear the pressure generated during the stamping process.

[0103] The die 330 is a consumable component that is detachably connected to the lower die holder 340, for example, by fasteners, to achieve precise fit during the stamping process. In addition, during high-intensity stamping, both the die 330 and the workpiece generate a lot of heat. The lower die holder 340 can be equipped with cooling channels to prevent overheating from affecting the performance of the die and the quality of the workpiece. At the same time, the lower die holder 340 has sufficient rigidity and strength and can be made of cast iron, steel or alloy materials to withstand the impact and pressure from the press and prevent deformation during the stamping process.

[0104] It is understandable that the lower mold assembly 320 consists of a cavity mold 330 and a lower mold base 340, and the cavity mold 330 is installed between the fixed plate 310 and the lower mold base 340. The stability and precision of the mold can be improved through precise design and assembly.

[0105] In some embodiments, such as Figure 7 As shown, the die 330 is provided with a first punch hole 331 and a second punch hole 332. The first punch body 110 extends into the first punch hole 331, and the second punch body 210 extends into the second punch hole 332.

[0106] The first punch hole 331 and the second punch hole 332 are disposed on the side of the die 330 facing the fixed plate 310, and are aligned with the first punch hole 311 and the second punch hole 312 respectively in the vertical direction. The first punch hole 331 and the first punch hole 311 are the same size and shape, and the second punch hole 332 and the second punch hole 312 are the same size and shape.

[0107] Specifically, the workpiece is positioned between the die 330 and the fixed plate 310. During the stamping process, the first punch body 110 penetrates the first punch hole 311 to stamp the workpiece. The first punch body 110 punches out part of the material and removes it through the first punch hole 331. After passing through the workpiece, the first punch body 110 continues to extend into the first punch hole 331. The second punch body 210 penetrates the second punch hole 312 to stamp the workpiece. The second punch body 210 punches out part of the material and removes it through the second punch hole 332. After passing through the workpiece, the second punch body 210 continues to extend into the second punch hole 332.

[0108] The first punch body 110 is tightly fitted with the first punch hole 311 and the first blanking hole 331, and the second punch body 210 is tightly fitted with the second punch hole 312 and the second blanking hole 332, respectively. This allows the punch body to act precisely on the workpiece during the stamping process, while reducing errors caused by poor fit. Furthermore, multiple different stamping processes can be completed in the same mold, thereby effectively improving production efficiency and workpiece quality.

[0109] It is understandable that the first punch hole 331 and the second punch hole 332 are used in conjunction with the first punch 10 and the second punch 20, so that the stamping equipment 1 can accurately process the workpiece through multi-step stamping, thereby improving the stamping efficiency, enabling it to complete multiple stamping steps in the same processing cycle, saving mold change time, and improving the processing accuracy of the workpiece.
