Description

Technical Field

[0001] This invention relates to the field of product processing technology, and more specifically, to a punching device. Background Technology

[0002] In the field of stamping die manufacturing, the traditional production mode generally adopts a transverse feeding method, that is, the strip material is continuously conveyed in the horizontal direction, and the stamped products are distributed perpendicular to the strip plane. This layout requires the die design to set up a lateral blanking mechanism perpendicular to the feeding direction in order to complete the forming of the product contour.

[0003] To address the placement issue of side-cut products, existing technologies typically utilize robotic arms for flipping operations. These robotic arms require three-axis coordinated movements—grabbing, rotating, and placing—resulting in a lengthy placement process for each product and consequently, an excessively long stamping cycle. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a novel punching device.

[0005] According to one aspect of the present invention, a punching apparatus is provided, comprising:

[0006] A first mold and a second mold are arranged opposite each other in a vertical direction. The second mold includes a first sub-mold and a second sub-mold arranged opposite each other in a horizontal direction. A material strip channel is provided between the first sub-mold and the second sub-mold. The material strip channel extends in the vertical direction and can pass through the material strip. The first sub-mold or the second sub-mold has a supporting part that can fix the material strip.

[0007] A cutting blade, one end of which is connected to the first mold, and the other end of which faces the supporting part. The first mold can drive the cutting blade to move along the vertical direction and approach the supporting part.

[0008] A receiving component, which faces the bearing portion, is capable of collecting the cut products.

[0009] Optionally, it further includes a first positioning element, which is disposed on the second mold and is capable of positioning the strip along the horizontal direction.

[0010] Optionally, the first positioning element includes a positioning block and a positioning pin, one end of the positioning pin is connected to the positioning block, and the other end of the positioning pin can pass through the first positioning hole of the material strip.

[0011] Optionally, the positioning block includes a support having a baffle extending along the vertical direction, the baffle being able to abut against the material strip that passes through it, and the positioning pin passing through the baffle and connected to the first positioning hole.

[0012] Optionally, the first positioning element further includes a first spring, which is sleeved on the outer periphery of the positioning pin and abuts against the baffle.

[0013] And / or, the support is provided with a groove, the groove opening faces the baffle, and the sidewall of the groove is on the same horizontal plane as the bearing part.

[0014] Optionally, it further includes a second positioning element, wherein the first mold includes an upper mold and a stripper plate arranged opposite each other along the vertical direction, one end of the second positioning element is connected to the stripper plate, and the other end of the second positioning element can pass through to the second positioning hole of the strip.

[0015] Optionally, it also includes a floating part, which is disposed on the second mold and can drive the material strip to move along the vertical direction.

[0016] Optionally, the floating part includes a limiting post and a floating block. The floating block is disposed in the second mold and can carry the material strip. One end of the limiting post is connected to the floating block, and the other end of the limiting post is connected to the upper mold.

[0017] Optionally, the floating part further includes a second spring, which is clamped between the limiting post and the upper mold;

[0018] And / or, the buoyant block includes a first part and a second part that are bent and connected, the first part being connected to the limiting post, and the second part having a support platform that is capable of abutting against the bottom of the material strip.

[0019] Optionally, it also includes a limiting member, one end of which is connected to the first mold, and the other end of which abuts against the receiving member.

[0020] Optionally, the first mold includes an upper mold and a stripper plate disposed opposite each other along the vertical direction, the limiting member is connected to the stripper plate, and the cutting blade is connected to the upper mold.

[0021] Optionally, the receiving component includes a third part and a fourth part that are bent and connected, the third part being disposed on the bearing portion and the fourth part extending to the outside of the bearing portion;

[0022] And / or, the receiving component has a suction nozzle connected to the carrier.

[0023] One technical advantage of the embodiments disclosed herein is that:

[0024] By setting a material strip channel between the first and second sub-dies, the material strip extends vertically and can pass through it. The first or second sub-dies has a support portion that can fix the material strip, allowing the cut product to fall from the support portion into the receiving component below under its own weight, and slide along the inclined surface of the receiving component for automatic collection. Afterwards, the receiving component can move laterally to the suction area, where suction cups can pick up the product and place it in the product holder, thus achieving product holder conveying. In this way, the receiving component only performs linear movement without flipping, which helps save punching time and avoids product damage and other abnormalities caused by flipping processes.

[0041] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0043] The present invention provides a punching device 100, which can be applied to the punching processing of strip 200 in industries such as electronics and hardware, so as to efficiently and accurately complete the punching separation of product 2001 from strip 200 and realize the convenient collection of product 2001.

[0044] like Figure 1 As shown, the blanking apparatus 100 provided in this embodiment of the invention includes:

[0045] A first mold 1 and a second mold 2 are arranged opposite each other in a vertical direction. The second mold 2 includes a first sub-mold 21 and a second sub-mold 22 arranged opposite each other in a horizontal direction. A material strip channel is provided between the first sub-mold 21 and the second sub-mold 22. The material strip channel extends in the vertical direction and can pass through the material strip 200. The first sub-mold 21 or the second sub-mold 22 has a supporting part 23, which can fix the material strip 200.

[0046] The cutting blade 3 has one end connected to the first mold 1 and the other end facing the support part 23. The first mold 1 can drive the cutting blade 3 to move along the vertical direction and approach the support part 23.

[0047] The receiving component 4 faces the bearing part 23 and is capable of collecting the cut product 2001.

[0048] like Figure 1 As shown, the first die 1 and the second die 2 are arranged opposite each other in a vertical direction, forming a basic punching frame structure. The first die 1 may include a die base, a pad, and a clamping plate, and the second die 2 may also include a die base, a pad, and a clamping plate. The first die 1 can move vertically to approach the second die 2.

[0049] The first die 1 can be made of high-strength alloy material, making its structure robust enough to withstand the reaction force during the punching process. The first die 1 can be connected and guided to the second die 2 through guide pillars, which can improve the accuracy of the first die 1 when it moves in the vertical direction, so that the cutting blade 3 on the first die 1 can accurately punch and cooperate with the strip 200 on the support part 23.

[0050] like Figure 2 As shown, the second mold 2 may include a first sub-mold 21 and a second sub-mold 22 arranged opposite each other in the horizontal direction, forming a strip channel between them. The strip 200 can pass through the strip channel in the vertical direction for punching. The first sub-mold 21 and the second sub-mold 22 may be made of high-strength alloy steel, giving the second mold 2 high hardness, high wear resistance, and good toughness, thus enabling it to withstand the enormous pressure and friction generated during the punching process, thereby ensuring the service life and punching accuracy of the punching device 100.

[0051] The strip channel is located between the first sub-mold 21 and the second sub-mold 22. Its width is designed according to the width of the strip 200 being processed. It is generally slightly larger than the width of the strip 200, which can ensure that the strip 200 passes through smoothly and effectively restrict the lateral movement of the strip 200, thereby improving the punching accuracy.

[0052] This design allows the strip 200 to move stably along a predetermined channel when entering the punching device, and restricts its horizontal swaying and deviation. Simultaneously, the support portion 23 on the first sub-die 21 or the second sub-die 22 firmly secures the strip 200. The support portion 23 can be specifically designed according to the characteristics of the strip 200 and the product 2001. For example, its shape may be adapted to the bottom contour of the product 2001, and its surface may have a special anti-slip treatment or a textured surface to increase friction. This ensures that the strip 200 will not shift due to the impact force of the cutter 3 when punching, thus guaranteeing the accuracy of the punching position and improving the dimensional and shape accuracy of the product 2001.

[0053] Among these measures, the inner wall of the conveyor belt channel can be polished to reduce the friction between the conveyor belt 200 and the inner wall of the channel, so that the conveyor belt 200 can move smoothly in the vertical direction and avoid deformation or damage to the conveyor belt 200 due to excessive friction.

[0054] like Figure 2 and Figure 3 As shown, a support portion 23, i.e. a processing portion, can be provided on the first sub-mold 21. The support portion 23 can be a groove 5112 structure with a certain depth and width. Its depth can be designed according to the size of the strip 200 to ensure that it can stably support the product 2001 on the strip 200, thereby facilitating the subsequent cutting process.

[0055] The surface of the bearing part 23 can be specially treated, such as by using a hard chrome plating process, to increase the surface hardness and wear resistance, while also increasing the friction between it and the strip 200 to prevent the strip 200 from moving during the punching process.

[0056] like Figure 2 and Figure 3 As shown, the cutting blade 3 is connected to the first mold 1, enabling the first mold 1 to drive the cutting blade 3 to move vertically and punch away the product 2001 on the strip 200. One end of the cutting blade 3 can be bolted to the lower surface of the first mold 1 to ensure a secure and reliable connection between the cutting blade 3 and the first mold 1, preventing loosening during the punching process. This allows for vertical punching, facilitating control of the punching process and reducing the risk of damage to the product 2001.

[0057] Driven by an external power source such as a hydraulic cylinder or pneumatic cylinder, the first die 1 drives the cutting blade 3 to reciprocate vertically. During the punching process, the first die 1 moves downward, causing the cutting blade 3 to gradually approach the strip 200 on the support part 23. When the cutting blade 3 contacts the strip 200, it applies pressure to the strip 200 to punch and separate the product 2001 from the strip 200. After punching is completed, the first die 1 moves upward, causing the cutting blade 3 to move away from the support part 23 and prepare for the next punching. In this way, this vertical punching method avoids the lateral forces that may be caused by oblique punching, thereby reducing the deformation of the strip 200 and the wear of the device caused by lateral forces.

[0058] In one embodiment, the cutter 3 can be made of materials such as high-speed steel. High-speed steel has high hardness and good wear resistance, so that it can maintain a sharp cutting edge during high-speed punching, thereby ensuring that the punched product 2001 has neat and smooth edges, without burrs or flash.

[0059] In one embodiment, the shape of the cutter 3 can be designed according to the shape of the product 2001. For example, if the product 2001 is rectangular, the cutting edge of the cutter 3 is also rectangular, and the size of the cutter 3 is slightly larger than the size of the product 2001, so as to ensure that the product 2001 can be completely cut off from the strip 200.

[0060] In one embodiment, an elastic gasket can be provided at the connection between the cutter 3 and the first mold 1. The elastic gasket is made of elastic materials such as rubber and has a certain elastic deformation capability. During the punching process, the elastic gasket can play a buffering role, reducing the impact force between the cutter 3 and the first mold 1, thereby extending the service life of the first mold 1. At the same time, it can also ensure the stability of the cutter 3 during the punching process and improve the punching quality.

[0061] like Figure 1 and Figure 3 As shown, the receiving component 4 is connected to the second mold 2 with its receiving end facing the carrier part 23, enabling it to collect the cut products 2001 through the receiving end, thereby realizing an automated production process. This also eliminates the need for manual collection of products 2001, reducing downtime during production and allowing the production line to operate continuously and stably, thus improving overall production efficiency.

[0062] The receiving end can be an inclined trough-shaped structure, with the inclination angle designed according to the falling speed of product 2001 and collection requirements. Generally, the inclination angle is between 30° and 60°. For example, an inclination angle of 45° can be selected so that the cut product 2001 can smoothly slide into the receiving part 4 under its own gravity, thereby realizing automatic collection.

[0063] In one embodiment, the receiving part 4 can be made of materials such as stainless steel. Stainless steel has the advantages of corrosion resistance and easy cleaning, which can ensure that the receiving part 4 is not corroded during long-term use, so as to maintain a smooth surface and reduce the friction between the product 2001 and the receiving part 4, thereby allowing the product 2001 to slide smoothly into the collection container.

[0064] In one embodiment, the surface of the receiving component 4 may be polished to improve the sliding performance of the product 2001, thereby ensuring the smooth collection of the product 2001.

[0065] During punching, the strip 200 is inserted from above the strip channel, allowing it to move vertically downwards until the product 2001 on the strip 200 is positioned above the support portion 23. By adjusting the position of the strip 200, the product 2001 is ensured to be accurately placed at the center of the support portion 23. Then, an external power source is activated, driving the first die 1 downwards. The first die 1 moves the cutter 3 closer to the strip 200 on the support portion 23. When the cutter 3 contacts the strip 200, pressure is applied, and the product 2001 is punched off. Afterwards, the cut product 2001, under its own weight, falls from the support portion 23 into the receiving member 4 below, sliding along the inclined surface of the receiving member 4 for automatic collection. Finally, the external power source drives the first die 1 upwards, moving the cutter 3 away from the support portion 23, returning to its initial position, and preparing for the next punching operation. By repeating the above steps, continuous strip punching can be achieved.

[0066] In this way, the strip 200 can continuously enter the punching device 100 for punching processing along the vertical direction through the strip channel. The first die 1, driven by the power device, can quickly and accurately drive the cutter 3 to reciprocate and achieve high-speed punching. Compared with the traditional intermittent punching device 100, the interval time between each punching is shortened, and the number of punchings per unit time is increased, thereby improving production efficiency.

[0067] like Figure 6 As shown, the cut product 2001, under its own weight, falls from the supporting part 23 into the receiving part 4 below, sliding along the inclined surface of the receiving part 4 for automatic collection. Afterwards, the receiving part 4 can move laterally to the suction area, where the suction cups inside the receiving part 4 can pick up the product 2001 and place it into the product holder 300, thus achieving conveying of the product holder 300. In this way, the receiving part 4 only performs linear movement without flipping, which helps save punching time and avoids abnormalities such as damage to the product 2001 caused by the flipping process.

[0068] Optionally, it also includes a first positioning element 5, which is disposed on the second mold 2 and is capable of positioning the strip 200 along the horizontal direction.

[0069] like Figure 1 and Figure 2 As shown, the second mold 2, also known as the lower mold, includes a first sub-mold 21, a second sub-mold 22, a lower mold base, and a lower backing plate. The lower backing plate is located between the first sub-mold 21, the second sub-mold 22, and the lower mold base. A first positioning element 5 can be provided on the lower mold base so that the first positioning element 5 can position the strip 200 passing through it in the horizontal direction, that is, the relative direction of the first sub-mold 21 and the second sub-mold 22, thereby improving the accuracy of subsequent punching.

[0070] Optionally, the first positioning member 5 includes a positioning block 51 and a positioning pin 52, one end of the positioning pin 52 is connected to the positioning block 51, and the other end of the positioning pin 52 can be inserted into the first positioning hole of the material strip 200.

[0071] like Figure 4 As shown, the positioning block 51 can be placed on the lower mold base, and the positioning pin 52 can be connected to the positioning block 51, so that the positioning pin 52 can form a threaded connection, snap-fit ​​connection or other connection with the first positioning hole of the strip 200, thereby realizing the positioning of the strip 200. The top opening of the positioning block 51 can be provided to facilitate the connection of the positioning pin 52.

[0072] Optionally, the positioning block 51 includes a support 511, the support 511 having a baffle 5111 extending along the vertical direction, the baffle 5111 being able to abut against the material strip 200 that passes through it, and the positioning pin 52 passing through the baffle 5111 and connected to the first positioning hole.

[0073] like Figure 4 As shown, the support 511 can be an L-shaped structure or a near-L-shaped structure, and its interior has a baffle 5111 extending in the vertical direction, which can be used to limit the passing material strip 200, so as to facilitate the convenient and reliable connection of the positioning pin 52. In this case, depending on the actual design, the support 511 and the baffle 5111 can be integrally formed, or they can be formed independently.

[0074] like Figure 4 As shown, the positioning block 51 may also include a connecting seat, which is connected to the support 511 in a vertical direction. The connecting seat is used to fix one end of the positioning pin 52, and the other end of the positioning pin 52 passes through the through hole of the baffle 5111 and is connected to the first positioning hole of the material belt 200.

[0075] In one embodiment, the connector may be Figure 4The L-shaped structure shown has one side abutting against the baffle 5111 and the other side parallel to the baffle 5111, so as to facilitate the assembly of the positioning block 51.

[0076] Optionally, the first positioning member 5 further includes a first spring 53, which is sleeved on the outer periphery of the positioning pin 52 and abuts against the baffle 5111.

[0077] And / or, the support 511 is provided with a groove 5112, the groove opening of the groove 5112 faces the baffle 5111, and the side wall of the groove 5112 is on the same horizontal plane as the bearing part 23.

[0078] like Figure 4 As shown, the positioning pin 52 may include a large-diameter portion and a small-diameter portion. One end of the large-diameter portion can be connected to one end of the small-diameter portion, the other end of the large-diameter portion can be connected to the connecting seat or support 511, and the other end of the small-diameter portion can be connected to the first positioning hole of the material strip 200. Depending on the actual design, the large-diameter portion and the small-diameter portion can be integrally formed, or they can be formed independently.

[0079] In one embodiment, an external thread can be provided on the small diameter portion, and a corresponding internal thread can be provided in the through hole of the baffle 5111, so that the positioning of the first positioning hole of the strip 200 can be achieved by utilizing the threaded engagement of the two.

[0080] In one embodiment, a first spring 53 may be fitted around the outer periphery of the small diameter portion. One end of the first spring 53 abuts against the large diameter portion, and the other end of the first spring 53 abuts against the baffle 5111. This allows the elastic deformation of the first spring 53 to adjust the insertion depth of the positioning pin 52 and the baffle 5111, thereby adjusting the positioning position of the positioning pin 52 to better adapt to the positioning requirements of different material strips 200.

[0081] In one embodiment, a force transmission rod 54 can also be provided, with one end of the force transmission rod 54 passing through the through hole of the connecting seat and connected to the large diameter part of the positioning pin 52. The other end of the force transmission rod 54 can be connected to the drive structure, so that the drive structure can drive the positioning pin 52 to move through the force transmission rod 54 and realize the engagement of the positioning pin 52 with the first positioning hole of the material strip 200.

[0082] In one embodiment, a horizontal groove 5112 can also be formed on the support 511, with the opening of the groove 5112 facing the baffle 5111, and the sidewall of the groove 5112 being on the same horizontal plane as the bearing portion 23. Thus, when punching the product 2001 of the strip 200 on the bearing portion 23, the groove 5112, being on the same horizontal plane, can also support the remaining products 2001 on the strip 200, thereby enabling vertical positioning of the strip 200, preventing punching abnormalities caused by strip 200 displacement during punching, and facilitating convenient punching of the remaining products 2001 on the strip 200, thus improving punching efficiency.

[0083] Optionally, it also includes a second positioning member 6. The first mold 1 includes an upper mold 11 and a stripper 12 arranged opposite to each other along the vertical direction. One end of the second positioning member 6 is connected to the stripper 12, and the other end of the second positioning member 6 can pass through the second positioning hole of the material strip 200.

[0084] like Figure 1 As shown, the first mold 1 may include an upper mold 11 and a stripper plate 12 arranged opposite each other along the vertical direction. The upper mold 11 includes an upper mold base, an upper pad, and an upper clamping plate. The upper pad is clamped between the upper mold base and the upper clamping plate. The upper mold 11 and the stripper plate 12 can be connected by guide posts. The upper mold 11 can move vertically relative to the stripper plate 12, and the upper mold 11 can also move vertically together with the stripper plate 12.

[0085] like Figure 3 As shown, one end of the second positioning member 6 can be connected to the stripper plate 12, and the other end of the second positioning member 6 can face the second positioning hole of the strip 200. During the process of the upper die 11 and the stripper plate 12 moving vertically together and approaching the support portion 23, the other end of the second positioning member 6 can pass through the second positioning hole of the strip 200 and connect with the strip 200, thereby positioning the strip 200 for reliable subsequent punching. The second positioning hole is typically located close to the product 2001 to be punched to improve punching accuracy.

[0086] Optionally, it also includes a floating part 7, which is disposed on the second mold 2 and can drive the material strip 200 to move along the vertical direction.

[0087] like Figure 2 As shown, the floating part 7 is provided on the second mold 2 and can float vertically on the second mold 2, so as to drive the material strip 200 it carries to move together to adjust the vertical position, thereby placing the product 2001 on the material strip 200 on the carrying part 23 for subsequent punching process.

[0088] Optionally, there are multiple floating parts 7, which are spaced apart on the second mold 2 so that different parts of the strip 200 can be supported by multiple floating parts 7, which helps to improve the reliability and controllability of the movement of the strip 200.

[0089] Optionally, the floating part 7 includes a limiting post 71 and a floating block 72. The floating block 72 is disposed on the second mold 2 and can carry the material strip 200. One end of the limiting post 71 is connected to the floating block 72, and the other end of the limiting post 71 is connected to the upper mold 11.

[0090] like Figure 2 As shown, the floating block 72 can be placed on the second mold 2. The floating block 72 can carry the strip 200 in the vertical direction to ensure the vertical position of the strip 200, so that the product 2001 on the strip 200 can be placed on the bearing part 23 for subsequent punching process.

[0091] Before punching, under the drive of the upper die 11, the limiting post 71 can drive the material strip 200 it carries to descend vertically through the floating block 72 until the product 2001 on the material strip 200 is on the bearing part 23, so as to facilitate the subsequent punching process. At the same time, it can also avoid the deformation of the material strip 200 caused by the strip plate 12 directly contacting the material strip 200, which helps to improve the reliability of punching. After punching is completed, under the drive of the upper die 11, the limiting post 71 can drive the material strip 200 it carries to rise vertically through the floating block 72 until the product 2001 on the material strip 200 leaves the bearing part 23, so as to facilitate the replacement of the product 2001.

[0092] Optionally, the floating part 7 further includes a second spring 73, which is clamped between the limiting post 71 and the upper mold 11;

[0093] And / or, the buoy 72 includes a first part and a second part that are bent and connected, the first part being connected to the limiting post 71, and the second part having a support platform that can abut against the bottom of the material belt 200.

[0094] like Figure 5As shown, one end of the second spring 73 can be abutted against the limiting post 71, and the other end of the second spring 73 can be abutted against the upper die 11. When the upper die 11 moves downward, the upper die 11 can compress the second spring 73, and the second spring 73 can undergo elastic deformation to buffer part of the pressure. This allows the upper die 11 to drive the material strip 200 it carries to descend slowly and smoothly in the vertical direction through the limiting post 71 and the floating block 72, so as to avoid abnormalities in the material strip 200 caused by sudden pressure changes. After the blanking is completed and the downward pressure applied to the upper die 11 is removed, the second spring 73 can elastically reset and drive the material strip 200 it carries to rise in the vertical direction to the initial position through the floating block 72. This can also save driving force and help reduce the overall energy consumption of the blanking device 100.

[0095] like Figure 2 As shown, the floating block 72 may include a first part and a second part (not shown in the figure) that are bent and connected. The first part is located on the second mold 2 and connected to the limiting post 71, and the second part extends into the material channel and is capable of carrying the material strip 200. The second part may be provided with a support platform for carrying the bottom of the material strip 200.

[0096] In one embodiment, the first part can be configured in an I-shape to facilitate the connection of its upper limit post 71 and to improve the structural stability of the buoy 72.

[0097] In one embodiment, the second part can be configured in an L-shape, with one sidewall of the L-shape connected to the first part and the other sidewall of the L-shape used to support the bottom of the material belt 200.

[0098] Optionally, it also includes a limiting member 8, one end of which is connected to the first mold 1, and the other end of which abuts against the receiving member 4.

[0099] like Figure 2 and Figure 3 As shown, one end of the limiting member 8 can be connected to the first mold 1, so that the first mold 1 can drive the limiting member 8 to move vertically until the other end of the limiting member 8 abuts against the receiving member 4. At this time, the limiting member 8 can push the receiving member 4 vertically downward to the avoidance position, thereby avoiding the receiving member 4 from crushing the product 2001 during the punching process, and also avoiding the receiving member 4 from interfering with the punching process. After the punching is completed, the first mold 1 can drive the receiving member 4 vertically upward to the receiving position through the limiting member 8, so that the punched product 2001 can fall into the receiving member 4.

[0100] In this design, the connection position between the limiting member 8 and the first mold 1 is set lower than the connection position between the limiting member 8 and the cutting blade 3 in the vertical direction. This allows the limiting member 8 to contact the receiving member 4 and press down to the avoidance position first during the vertical downward movement of the first mold 1, and then the cutting blade 3 contacts the product 2001 and performs punching, thereby ensuring the safety of the punching process.

[0101] In one embodiment, the limiting member 8 may be in the form of a long handle to facilitate its connection with the first mold 1. Its end is oriented towards the receiving member 4 to facilitate contact or abutment with the receiving member 4.

[0102] In one embodiment, a third spring can be provided between the receiving member 4 and the bearing surface of the bearing part 23, so that the third spring can be continuously compressed during the process of the limiting member 8 pushing the receiving member 4 vertically downward to the avoidance position. After the pressure of the limiting member 8 is removed, the third spring can elastically reset and drive the receiving member 4 vertically upward to the receiving position. At this time, it is only necessary to set the other end of the limiting member 8 to abut against the receiving member 4. No connection is required, which can also simplify the assembly process of the punching device 100.

[0103] Optionally, the first mold 1 includes an upper mold 11 and a stripper 12 disposed opposite to each other along the vertical direction, the limiting member 8 is connected to the stripper 12, and the cutting blade 3 is connected to the upper mold 11.

[0104] like Figure 1 As shown, the first mold 1 may include an upper mold 11 and a stripper plate 12 arranged opposite each other along the vertical direction. The upper mold 11 may include an upper mold base, an upper pad, and an upper clamping plate. The upper pad is clamped between the upper mold base and the upper clamping plate. The upper mold 11 and the stripper plate 12 may be connected by guide posts. The upper mold 11 may move vertically relative to the stripper plate 12, and the upper mold 11 may also move vertically together with the stripper plate 12.

[0105] like Figures 1 to 3 As shown, the limiting member 8 can be connected to the stripper plate 12, so that the stripper plate 12 can drive the limiting member 8 to move vertically until the other end of the limiting member 8 abuts against the receiving member 4. At this time, the limiting member 8 can push the receiving member 4 vertically downward to the avoidance position, thereby avoiding the receiving member 4 from crushing the product 2001 during the punching process, and also avoiding the receiving member 4 from interfering with the punching process. After the punching is completed, the stripper plate 12 can drive the receiving member 4 vertically upward to the receiving position through the limiting member 8, so that the punched product 2001 can fall into the receiving member 4.

[0106] The device is configured such that, in the vertical direction, the limiting member 8 is connected to the stripper plate 12 and the cutting blade 3 is connected to the upper mold 11. This allows the limiting member 8 to contact the receiving member 4 and press down to the avoidance position before the cutting blade 3 contacts the product 2001 and performs punching, thus ensuring the safety of the punching process.

[0107] Optionally, the receiving component 4 includes a third part 41 and a fourth part 42 that are bent and connected, the third part 41 being disposed on the bearing part 23, and the fourth part 42 extending to the outside of the bearing part 23;

[0108] And / or, the receiving part 4 has a suction nozzle connected to the carrier part 23.

[0109] like Figure 3 As shown, the included angle between the third part 41 and the fourth part 42 is adapted to the structure of the support part 23, such that the third part 41 is located on the support surface of the support part 23, while the fourth part 42 can extend to the outside of the support part 23. In this way, the punched product 2001 can fall into the third part 41 and enter the interior of the receiving part 4 through the fourth part 42 for subsequent recycling.

[0110] During the punching process, the cut-off product 2001 will fall smoothly into the receiving component 4 under its own weight or guided by the receiving component 4, and will be collected into a designated container through the guiding structure (such as an inclined slide) within the receiving component 4. This design eliminates the need for manual collection of product 2001, reduces downtime during production, enables the production line to operate continuously and stably, and thus improves overall production efficiency.

[0111] In one embodiment, a suction nozzle can also be provided in the receiving part 4. The suction nozzle can use negative pressure to adsorb the product 2001 that has fallen after the punching is completed, and guide the product 2001 to fall into a predetermined position in the receiving part 4.

[0112] The present invention also provides a conveying system, including a material belt 200 and the aforementioned punching device 100, wherein the receiving member 4 is detachably connected to the bearing portion 23 along the vertical direction. Thus, the cut product 2001 can fall from the bearing portion 23 into the receiving member 4 below under its own weight, and slide along the inclined surface of the receiving member 4 for automatic collection.

[0113] Depending on the product 2001 being cut, different receiving parts 4 can be replaced, thereby simplifying the receiving process.

[0114] Optionally, it also includes a product seat 300, wherein the receiving member 4 is movable between the punching device 100 and the product seat 300.

[0115] like Figure 6 As shown, the cut product 2001, under its own weight, falls from the supporting part 23 into the receiving part 4 below, sliding along the inclined surface of the receiving part 4 for automatic collection. Afterwards, the receiving part 4 can move laterally to the suction area, where the suction cups inside the receiving part 4 can pick up the product 2001 and place it into the product holder 300, thus achieving conveying of the product holder 300. In this way, the receiving part 4 only performs linear movement without flipping, which helps save punching time and avoids abnormalities such as damage to the product 2001 caused by the flipping process.
