Description

Technical Field

[0001] This invention relates to the field of blanking technology, and in particular to a blanking device and an automated blanking system. Background Technology

[0002] In the field of metal stamping, for single-unit products that require post-processing such as electroplating, the process route is often "integral stamping - integrated post-processing (such as cleaning, electroplating) - single-unit removal". Among them, the key "single-unit removal" process usually adopts the following operation mode: the strip that has completed integrated post-processing is wound into a coil as the incoming material, and the single-unit is removed and separated by step feeding on a single-punch die and a punch press.

[0003] Specifically, each roll of material contains approximately 1,000 to 3,000 individual units, depending on the product structure and die pitch. During production, once each roll is depleted, the machine must be stopped for manual material replacement. Operators must manually pull and thread the head of the new roll until it is accurately delivered to the cutting edge working area of ​​the die. This manual material replacement method is time-consuming and detrimental to punching efficiency. Summary of the Invention

[0004] The main objective of this invention is to propose a die-cutting device and an automated die-cutting system, which aims to automate the feeding of materials and improve the working efficiency of the die-cutting device.

[0005] To achieve the above objectives, the present invention provides a punching device comprising:

[0006] A blanking mechanism includes an upper die assembly and a lower die assembly, with a blanking station formed between the upper die assembly and the lower die assembly; A feeder frame, installed on the lower die assembly, the feeder frame having a guide groove extending along the feeding direction to the punching station; and A feeding mechanism acts on the strip to guide it into the guide groove and move it along the guide groove to the punching station.

[0007] In one embodiment, the feeding frame includes two oppositely arranged feeding sub-frames, which extend along the feeding direction, and each feeding sub-frame has the guide groove formed thereon; the strip includes a guiding area on both sides and a punching area between the two guiding areas. The two material guiding areas are respectively embedded in the two guide grooves, and the upper and lower sides of the punching area are respectively arranged face-to-face with the upper die assembly and the lower die assembly.

[0008] In one embodiment, at least one wall of the guide groove is inclined at the material inlet end so that the opening of the guide groove at the material inlet end gradually decreases in the feeding direction.

[0009] In one embodiment, the upper mold assembly is equipped with a downwardly extending positioning pin, the strip is provided with a positioning hole, and the upper wall of the guide groove is provided with a clearance position so that the positioning pin passes through the clearance position and extends into the positioning hole.

[0010] In one embodiment, the material feeding frame is mounted to the lower mold assembly via a first elastic element.

[0011] In one embodiment, the edge of the material feeding frame is provided with a limiting groove, and a limiting pin is fixed on the lower mold assembly. The limiting pin can move relative to the limiting groove. The limiting pin and the limiting groove abut against each other to restrict the upward movement of the material feeding frame.

[0012] In one embodiment, the blanking equipment further includes a hanging plate, the lower end of which is fixedly connected to the upper die assembly, and the upper end of which is used to hang on the machine base of the automated blanking system.

[0013] In one embodiment, the upper mold assembly includes an upper pad, a clamping plate, a stripping plate, and a stripping plate arranged sequentially from top to bottom. The clamping plate and the upper pad are fixed together, and the stripping plate and the stripping plate are fixed together. The clamping plate and the stripping plate are connected by a second elastic element. The hanging plate is fixed to the upper pad. And / or, the lower die assembly includes a lower die plate and a lower pad arranged sequentially from top to bottom, the lower die plate and the lower pad are fixedly connected, and the bottom of the lower pad is used to contact the operating table of the punching equipment.

[0014] The present invention also proposes an automated blanking system, comprising: Machine tool; The power unit is installed on the machine tool; In the aforementioned punching equipment, the lower die assembly is located on the machine base, and the upper die assembly is connected to the output end of the power component.

[0015] In one embodiment, the automated die-cutting system includes a plurality of the threading racks, each of which has a different size of guide groove.

[0016] The technical solution of this invention automates the blanking process by incorporating a blanking mechanism, a feeding frame, and a material feeding mechanism within a blanking equipment. The blanking mechanism includes an upper die assembly and a lower die assembly, with a blanking station formed between them. The feeding frame is mounted on the lower die assembly and has a guide groove extending along the feeding direction to the blanking station. The material feeding mechanism acts on the strip to guide it into the guide groove and move it along the guide groove to the blanking station. Compared to manual material feeding in the prior art, this invention uses a feeding frame with a guide groove and a material feeding mechanism within the blanking equipment. The material feeding mechanism drives the strip movement, and the guide groove on the feeding frame constrains the strip's movement path, thereby automating the material feeding process, avoiding equipment downtime, and improving blanking efficiency. Simultaneously, the guide groove ensures the accuracy of material feeding and guarantees a high pass rate in the blanking process. Attached Figure Description

[0024] In the field of metal stamping, for single-unit products that require post-processing such as electroplating, the process route of "integral stamping forming - integrated post-processing (such as cleaning, electroplating) - single-unit removal" is often adopted. Among them, the key "single-unit removal" process usually adopts the following operation mode: the strip material that has completed integrated post-processing is wound into a coil as the incoming material, and the single-unit material is removed and separated by step feeding on a single-punch die and a punch press.

[0025] The existing operating model suffers from significant efficiency bottlenecks and reliance on manual labor. Specifically, each roll of material contains approximately 1,000 to 3,000 individual units, depending on the product structure and die pitch. During production, once each roll is depleted, the machine must be stopped for manual material replacement. Operators must manually pull and thread the head of the new roll until it is accurately delivered to the die's cutting edge. This manual threading process takes approximately 5 to 10 minutes, while the actual punching production time for each roll is only 7 to 15 minutes. This means that production is frequently interrupted by downtime for material replacement, and the manual threading time accounts for a very high proportion of the production cycle, resulting in low equipment utilization and severely restricting overall production efficiency.

[0026] In addition, relying entirely on manual material threading has problems such as high labor intensity, safety risks during operation, high dependence on the experience of operators, and potential increase in the initial scrap rate due to inaccurate material threading.

[0027] This invention proposes a punching device.

[0028] Please see Figures 1 to 3 In one embodiment of the present invention, the blanking equipment includes a blanking mechanism 100, a material feeding frame 200, and a feeding mechanism. The blanking mechanism 100 includes an upper die assembly 110 and a lower die assembly 120, and a blanking station 130 is formed between the upper die assembly 110 and the lower die assembly 120. The material feeding frame 200 is installed on the lower die assembly 120 and has a guide groove 210. The guide groove 210 extends along the feeding direction to the blanking station 130. The feeding mechanism acts on the strip 400 to introduce the strip 400 into the guide groove 210 and move the strip 400 along the guide groove 210 to the blanking station 130.

[0029] It is understood that the blanking equipment in this invention is not applied to a punch press, but rather to an automated blanking system. The automated blanking system includes a machine base, a power unit mounted on the machine base, and blanking equipment. The power unit is the power source for the blanking equipment, used to drive the action of the blanking mechanism 100 of the blanking equipment.

[0030] The blanking equipment is used to individually blank and separate strip 400 that has undergone previous processing, such as stamping or electroplating. Specifically, the blanking equipment includes a blanking mechanism 100, a feeding rack 200, and a feeding mechanism. The blanking mechanism 100 is the component that performs the blanking action, and it includes an upper die assembly 110 and a lower die assembly 120. The upper die assembly 110 is connected to the output end of a power component, allowing it to reciprocate vertically under the drive of the power component. The lower die assembly 120 is fixed to the machine base and is positioned opposite the upper die assembly 110, forming a blanking station 130 between them. At the blanking station 130, the strip 400 is subjected to the combined stamping action of the upper die assembly 110 and the lower die assembly 120, enabling the strip 400 to be blanked and separated into individual parts.

[0031] The feeder 200 is mounted on the lower die assembly 120, and a guide groove 210 is formed thereon, extending along the feeding direction of the strip 400. Understandably, the guide groove 210 is used to constrain and guide the movement of the strip 400 to prevent it from skewing or warping during movement, ensuring that the strip 400 can move straight and smoothly to the preset position. Since the strip 400 needs to move to the blanking station 130 for processing, the guide groove 210 needs to extend at least to the blanking station 130 to meet the requirement that the strip 400 needs to move to the blanking station 130.

[0032] The feeding mechanism provides the power for the movement of the strip 400. Specifically, the feeding mechanism can be located in front of the inlet of the guide groove 210 of the feeding frame 200, integrated on the feeding frame 200, or located in other positions on the machine tool of the automated punching system, as long as the feeding mechanism can drive the strip 400 to move. No restrictions are placed on the specific installation location of the feeding mechanism. The feeding mechanism can be any device that can provide stable linear feeding power, such as a clamping roller feeder, pneumatic gripper, or friction wheel. The specific structure of the feeding mechanism is existing technology and will not be described in detail here. The feeding mechanism automatically feeds the head of the strip 400 into the inlet of the guide groove 210 and continuously or intermittently drives the strip 400, causing it to move along the path defined by the guide groove 210 until the first area to be processed on the strip 400 is accurately moved below the punching station 130. After the punching operation is completed, the feeding mechanism continues to drive the strip 400 to move so that the next area to be processed moves below the punching station 130. This process is repeated until all areas on the material strip 400 that are to be processed are completed.

[0033] The technical solution of the present invention is to provide a punching mechanism 100, a material feeder 200 and a feeding mechanism in a punching equipment. The punching mechanism 100 includes an upper die assembly 110 and a lower die assembly 120, and a punching station 130 is formed between the upper die assembly 110 and the lower die assembly 120. The material feeder 200 is installed on the lower die assembly 120 and has a guide groove 210. The guide groove 210 extends along the feeding direction to the punching station 130. The feeding mechanism acts on the strip 400 to introduce the strip 400 into the guide groove 210 and move the strip 400 along the guide groove 210 to the punching station 130. Compared to the manual feeding method in the prior art, the present invention sets up a feeding frame 200 with a guide groove 210 and a feeding mechanism in the punching equipment. The feeding mechanism drives the material strip 400 to move, and the guide groove 210 on the feeding frame 200 constrains the movement path of the material strip 400, thereby realizing the automation of feeding, avoiding downtime of the punching equipment and improving punching efficiency. At the same time, the setting of the guide groove 210 ensures the accuracy of feeding the material strip 400 and ensures the pass rate of punching.

[0034] Please see Figure 3 In an embodiment of the present invention, the feeding frame 200 includes two oppositely arranged feeding sub-frames 201, which extend along the feeding direction. Each feeding sub-frame 201 has a guide groove 210 formed on it. The strip 400 includes a guiding area on both sides and a punching area between the two guiding areas. The two guiding areas are respectively embedded in the two guide grooves 210, and the upper and lower sides of the punching area can be respectively arranged face-to-face with the upper die assembly 110 and the lower die assembly 120.

[0035] Specifically, in one embodiment of the present invention, the material feeder 200 in the punching equipment is arranged in a split configuration. That is, the material feeder 200 is not a single block structure, but is composed of two oppositely arranged material feeder sub-feeders 201. The two material feeder sub-feeders 201 are parallel to each other. In one embodiment, the connection direction of the two material feeder sub-feeders 201 is perpendicular to the feeding direction. Both material feeder sub-feeders 201 extend along the feeding direction, and each material feeder sub-feeder 201 has a guide groove 210 formed on it, with the openings of the two guide grooves 210 facing each other. The two guide grooves 210 are arranged parallel to each other to jointly define the feeding channel.

[0036] Correspondingly, the material strip 400 includes guide zones located on both sides and a blanking zone between the two blanking zones in its width direction. The blanking zone can obtain multiple target products after blanking separation, while the two guide zones mainly serve the functions of conveying and guiding.

[0037] During the automatic feeding process, the conveyor belt 400 moves forward under the drive of the feeding mechanism. The guide areas on both sides of the conveyor belt 400 are respectively embedded in the guide grooves 210 on the corresponding feeding sub-frames 201. The cross-sectional shape of the guide grooves 210 matches the thickness and width of the guide areas, thereby accurately positioning and constraining both sides of the conveyor belt 400 during its movement, effectively preventing the conveyor belt 400 from swaying or twisting in the horizontal plane.

[0038] Meanwhile, due to the split design of the feeder 200, sufficient open space is left between the two feeder sub-feeders 201. Thus, when the two guide areas of the strip 400 are constrained within the guide grooves 210 on both sides, the punching area in the middle is completely exposed within this open space. This ensures that the upper and lower surfaces of the punching area are unobstructed, allowing for precise, face-to-face alignment and engagement with the lower surface of the upper die assembly 110 and the upper surface of the lower die assembly 120, respectively. During downward punching, the upper die assembly 110 can directly act on the exposed punching area to separate the target product, while the guide areas on both sides continue to be conveyed forward under the guidance of the guide grooves 210, preparing for the punching of the next target product.

[0039] In this way, by setting two opposing feeding sub-frames 201, the guide grooves 210 on both sides ensure the straightness and stability of the feeding, while the open space in the middle fully guarantees the effective execution space of the punching action, thereby further improving the accuracy and reliability of the punching process on the basis of realizing automatic feeding.

[0040] Understandably, when the conveyor belt 400 enters the guide groove 210, there is a certain clearance between the conveyor belt 400 and the groove wall of the guide groove 210. This clearance is used to meet the movement requirements of the conveyor belt 400 relative to the guide groove 210. This clearance should not be too large to avoid deviation of the conveyor belt 400 during movement. No specific value for this clearance is limited here, as long as it ensures the normal movement of the conveyor belt 400 without affecting the accuracy of its trajectory.

[0041] Of course, in other embodiments, the material feeding rack 200 can also be an integral structure, as long as it has a hollowed-out design in the part corresponding to the arbitration station to avoid affecting the punching action.

[0042] Please see Figure 3 and Figure 4 In an embodiment of the present invention, at least one wall of the guide groove 210 is inclined at the material receiving end so that the opening of the guide groove 210 at the material receiving end gradually decreases in the feeding direction.

[0043] Understandably, the guide groove 210 has a straight section, and the strip 400 moves along the straight section of the guide groove 210 to the punching station 130. The feeder 200 has a certain height, and correspondingly, the guide groove 210 also has a certain height and groove width. Driven by the feeding mechanism, when the head of the strip 400 just enters the guide groove 210, there may be a slight deviation between the head of the strip 400 and the groove opening of the guide groove 210. If the groove opening of the guide groove 210 is also set as a straight section, the strip 400 may directly hit the vertical groove edge of the guide groove 210 and get stuck. In view of this, in one embodiment of the present invention, at least one groove wall of the guide groove 210 is inclined at the end where the strip 400 first contacts.

[0044] Specifically, the inclined groove wall is roughly flared out, or it is a guide slope. In the vertical direction of the punching equipment, the guide slope can be any of the top wall, bottom wall, or side wall of the guide groove 210. In another embodiment, the opposite side walls of the guide groove 210 at the material feeding end, such as the top and bottom walls, can be simultaneously inclined relative to each other. This causes the opening of the guide groove 210 at the material feeding end to gradually decrease along the feeding direction, eventually smoothly transitioning to a stable cross-section consistent with the dimensions of the straight section of the main body of the guide groove 210.

[0045] Thus, in the initial stage of the automatic feeding process, when the feeding mechanism pushes the head of the strip 400 towards the guide groove 210, even if there is a slight alignment deviation or a slight upward or downward curve in the initial position of the strip 400 head, its end or edge will first contact the inclined groove wall. Due to the guiding effect of the inclined surface, the strip 400 head will slide along the inclined surface under the continuous forward thrust and be automatically corrected in position and posture, thereby being smoothly guided into the gradually narrowing groove opening, and finally completely entering the straight section of the guide groove 210 with a stable cross-sectional size. This avoids the problem of feeding jamming and also reduces the alignment accuracy requirements of the strip 400 in the initial stage of feeding.

[0046] Please see Figures 1 to 3 In an embodiment of the present invention, the upper mold assembly 110 is equipped with a downwardly extending positioning pin, the strip 400 is provided with a positioning hole, and the upper groove wall of the guide groove 210 is provided with a clearance 220 so that the positioning pin passes through the clearance 220 and extends into the positioning hole.

[0047] Understandably, to ensure the quality of the punching process, the positioning of the punching station 130 needs to be precise. Specifically, in an embodiment of the present invention, a positioning pin is installed at the bottom of the upper die assembly 110, extending along the vertical direction of the punching equipment. At least one positioning pin is provided; in the embodiment shown in the figures of the present invention, multiple positioning pins are spaced apart along the feeding direction. The positioning pins are typically made of a high-hardness material, with a tapered lower end or a guide bevel. No restrictions are placed on the material, specific shape, or number of the positioning pins. Correspondingly, the strip 400 is provided with positioning holes, the shape, number, and size of which match the positioning pins. In one embodiment, the diameter of the positioning hole is slightly larger than the outer diameter of the positioning pin to facilitate the insertion or removal of the positioning pin from the positioning hole. Understandably, to avoid the positioning affecting the punching position of the strip 400, the positioning hole is located in the guide area of ​​the strip 400.

[0048] Understandably, the guide area of ​​the material strip 400 is embedded in the guide groove 210 of the material feeder 200, and the upper wall of the guide groove 210 will obstruct the downward movement of the positioning pin. Therefore, this invention provides a dedicated clearance 220 on the upper wall of the guide groove 210, directly opposite the path of the downward movement of the positioning pin. This clearance 220 can be a notch or through hole penetrating the upper groove wall, with a size slightly larger than the diameter of the positioning pin, to ensure that the positioning pin can pass through unobstructed.

[0049] Please see Figure 1 and Figure 2 In an embodiment of the present invention, the material feeding rack 200 is mounted on the lower mold assembly 120 via a first elastic member 310.

[0050] Specifically, the lower end of the first elastic element 310 is fixed to the lower die assembly 120, and the upper end of the first elastic element 310 is fixedly connected to the bottom of the feeder 200. Thus, on the one hand, when the upper die presses down, if the strip 400 has slight waviness, uneven thickness, or experiences abnormal resistance, the compression of the first elastic element 310 can absorb this deviation and stress, preventing the strip 400 from being forcibly flattened and deformed or damaged, thereby enhancing the adaptability of the blanking equipment to fluctuations in materials and production conditions. On the other hand, when the strip 400 enters the guide groove 210 under the drive of the feeding mechanism, if there are slight height changes or unevenness in a localized area of ​​the strip 400, it will generate an upward pushing force on the groove wall of the guide groove 210, such as the upper groove wall. At this time, the feeder 200 can overcome the elastic force of the first elastic element 310 and generate a small, upward elastic floating displacement relative to the lower die assembly 120. This floating effect prevents jamming, scratching, or abnormal wear caused by rigid contact between the strip 400 and the guide groove 210. On one hand, after the blanking operation is completed, the upper die assembly 110 moves upward relative to the lower die assembly 120. At this time, the strip 400 may move upward under the elastic force of the first elastic element 310, causing the feeder 200 to automatically reset to its initial position, preparing for the next guiding operation. In one embodiment, the first elastic element 310 is configured as a spring, sheet metal, etc.

[0051] Please see Figures 1 to 3 In an embodiment of the present invention, the edge of the material feeding rack 200 is provided with a limiting groove 230, and a limiting pin is fixed on the lower mold assembly 120. The limiting pin can move relative to the limiting groove 230. The limiting pin and the limiting groove 230 abut against each other to limit the upward movement of the material feeding rack 200.

[0052] Understandably, the material threading frame 200 is mounted on the lower die assembly 120 via the first elastic member 310. To prevent the material threading frame 200 from excessively moving upwards and losing its working position or affecting the guiding accuracy, the present invention also provides a limiting structure. Specifically, the limiting structure includes a limiting groove 230 and a limiting pin, wherein the limiting groove 230 is located on the edge of the material threading frame 200. In the embodiment shown in the figures of the present invention, both material threading sub-frames 201 are provided with limiting grooves 230, and the limiting grooves 230 are located on the side of one material threading sub-frame 201 away from the other material threading sub-frame 201. The axis of the limiting pin is approximately parallel to the floating direction of the material threading frame 200, that is, along the vertical direction. In one embodiment, the limiting pin includes a connected pin body and a limiting head, wherein the pin body is fixed on the lower die assembly 120. During the extension and retraction of the first elastic member 310, the material threading frame 200 is driven to float up and down, causing the limiting groove 230 to move up and down relative to the limiting pin. When the limiting head of the limiting pin abuts against the bottom of the limiting groove 230, the upward movement of the material feeder 200 is restricted. Thus, the cooperation between the limiting pin and the limiting groove 230 limits the upward travel of the material feeder 200, preventing it from leaving its working position.

[0053] In one embodiment, along the feeding direction, the edge of the feeding rack 200 is provided with a plurality of spaced limiting grooves 230, and correspondingly, a plurality of limiting pins are also provided. The limiting pins and the limiting grooves 230 correspond one to one, further avoiding the possibility of the feeding rack 200 leaving the working position.

[0054] Please see Figure 1 and Figure 2 In an embodiment of the present invention, the punching equipment further includes a hanging plate 320, the lower end of which is fixedly connected to the upper die assembly 110, and the upper end of which is used to hang on the machine base of the automated punching system.

[0055] It is understood that the blanking equipment of this invention is suitable for automated blanking systems. The blanking equipment needs to be installed on a machine base, wherein the lower die assembly 120 is fixed on the machine base, and the upper die assembly 110 also needs to be installed on the machine base, located above the lower die assembly 120. In one embodiment, a hanging plate 320 is fixed on the upper die assembly 110, and the upper die assembly 110 is hung on the machine base via the hanging plate 320, so as to be located above the lower die assembly 120. Thus, the connection method between the blanking equipment and the machine base is simplified by the setting of the hanging plate 320. In one embodiment, two hanging plates 320 are provided at intervals on the upper die assembly 110 of the blanking equipment to improve the connection stability between the upper die assembly 110 and the machine base. No specific limitations are made on the specific structure and number of the hanging plates 320.

[0056] Please see Figure 1 and Figure 2In an embodiment of the present invention, the upper mold assembly 110 includes an upper pad 111, a clamping plate 112, a pad removal plate 113, and a stripping plate 114 arranged sequentially from top to bottom. The clamping plate 112 is fixed to the upper pad 111, the pad removal plate 113 is fixed to the stripping plate 114, and the clamping plate 112 and the pad removal plate 113 are connected by a second elastic member 115; the hanging plate 320 is fixed to the upper pad 111. And / or, the lower die assembly 120 includes a lower die plate 121 and a lower pad 122 arranged sequentially from top to bottom. The lower die plate 121 and the lower pad 122 are fixedly connected, and the bottom of the lower pad 122 is used to contact the operating table of the punching equipment.

[0057] The blanking mechanism 100 of a blanking device typically used on a punch press has an upper die assembly 110 with an upper die holder and die shank fixed above an upper pad 111, and a lower die assembly 120 with a lower die holder fixed below a lower pad 122. The bottom of the lower die holder is provided with feet to accommodate the height of the punch press. It is understood that the blanking device of this invention is suitable for automated blanking systems, not for use on a punch press. Thus, the upper die assembly 110 of this invention eliminates the need for an upper die holder and die shank, and the lower die assembly 120 eliminates the need for a lower die holder and feet, thereby further simplifying the blanking device and reducing its cost.

[0058] This invention also proposes an automated blanking system, which includes a machine base, a power unit, and a blanking device. The specific structure of the blanking device is as described in the above embodiments.
