Description

Technical Field

[0001] This invention relates to the field of aluminum processing equipment technology, and in particular to an aluminum strip cutting and punching equipment. Background Technology

[0002] Aluminum strips, as a common metal profile, are widely used in architectural decoration, transportation, electronics, photovoltaic brackets, and other fields. In the production and processing of aluminum strips, long strips typically require cutting (cutting) and punching according to actual usage requirements. Traditional processing methods often involve manual feeding combined with a single cutting machine. Operators manually place the aluminum strips at the cutting station and cut them to preset dimensions. If punching is required, the strips must be transferred to a separate punching machine. This manual operation method is not only inefficient and labor-intensive, but the separate cutting and punching processes result in long turnaround times. Furthermore, the operator's hands are close to the cutting blades during manual feeding, posing a significant safety hazard.

[0003] To overcome the shortcomings of manual feeding, existing technologies have developed aluminum strip processing equipment with automatic feeding functions. For example, Chinese patent publication CN119857797A discloses an aluminum strip punching device with automatic feeding function, which includes a punching assembly, a docking assembly, and a positioning and picking assembly connected in sequence. The punching assembly is also equipped with a feeding roller assembly. The positioning and picking assembly includes a product positioning clamping part and a pushing part. The product positioning clamping part raises the stacked long strip products by the thickness of one product at a time. The pushing part is equipped with a movable pushing plate that pushes the product out by pressing against the end of the topmost product. This solution positions and pushes out the stacked long strip products individually through the positioning and picking assembly, and then the products are gradually pushed into the punching equipment for punching through the docking assembly and the feeding roller assembly, which reduces the workload of the operator to a certain extent. However, this technical solution still has obvious shortcomings: First, it pushes the top layer of products in a stacked state, which requires the product positioning and clamping part to achieve layer-by-layer rising, making the structure relatively complex and the equipment cost high; Second, the method of pushing the insert plate to pick up the material from above requires high clamping stability of the aluminum strip, and the aluminum strip is prone to displacement during the picking process; Third, the equipment only has a punching function, and the cutting of aluminum strip still needs to be completed separately with the help of other equipment, and the process is not effectively integrated.

[0004] Furthermore, patent document CN220112843U discloses an automatic switching aluminum strip cutting tool assembly, which includes a cutting table with cutting tools mounted on its upper surface. Fixed frames are mounted on both sides of one end of the cutting table, and a positioning mechanism is located in the middle of the cutting table. The positioning mechanism includes a fixed plate, a positioning plate, a first screw, and a positioning block. A second screw is threadedly connected to the top of the positioning plate, and the positioning block is fixed to one end of the first screw. A pushing mechanism for pushing aluminum strips is located on the back of the positioning plate. This solution, through the cooperation of the second screw and a scale, allows multiple aluminum strips to be stably stacked between the fixed plate and the positioning plate, and the pushing mechanism pushes the aluminum strips onto the cutting tool for cutting. However, this technical solution also has many drawbacks: First, the equipment only involves the cutting process and does not have a punching function. If punching is required after the aluminum strip is cut, it still needs to be transferred to other equipment for processing. The process turnover leads to low efficiency and loss of precision. Second, in this solution, multiple aluminum strips are directly stacked between the fixed plate and the positioning plate. When pushing, the upper aluminum strip and the lower aluminum strip are prone to relative sliding and friction, which not only affects the feeding accuracy but also easily causes scratches on the surface of the aluminum strip. Third, when the aluminum strips are directly stacked, the surface oxide layer or residual oil stains are prone to sticking together. When the pushing mechanism pushes, it may bring out multiple aluminum strips at once, resulting in feeding failure.

[0005] In summary, existing aluminum strip cutting and punching equipment suffers from the following main technical problems: the stacking feeding method is unreasonable; the top-layer pushing method requires a lifting mechanism, resulting in a complex structure; direct stacking and pushing easily leads to friction scratches and adhesion between aluminum strips, lacking effective anti-adhesion and separation measures, resulting in poor feeding reliability; the cutting and punching processes are separated, leading to low processing efficiency; and the aluminum strip's positioning at the feeding and cutting ends is inadequate, affecting processing accuracy. To address these problems, this invention provides an aluminum strip cutting and punching equipment to solve them. Summary of the Invention

[0006] Based on this, it is necessary to provide an aluminum strip cutting and punching device to address the aforementioned technical problems. This device separates the stacked aluminum strips one by one through a partition support structure, avoiding direct contact and friction between the aluminum strips and effectively preventing scratches on the surface of the aluminum strips. It realizes an automatic feeding method that separates the aluminum strips one by one from the stacked state and pushes the bottom layer of aluminum strips. It also uses the weight of the aluminum strips themselves to achieve automatic replenishment. The structure is simple and the cost is low. During the cutting process, the limiting structure of the lower die component accurately limits the aluminum strips, thereby realizing full automation and high-precision processing of aluminum strips from feeding and delivery to cutting.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An aluminum strip cutting and punching equipment includes a frame, and the top surface of the frame is provided with a first table and a second table; A limiting mechanism is provided on the first platform to limit the placement of stacked aluminum strips, and the limiting structure is provided with a separating support structure, which is used to separate the stacked aluminum strips one by one. A feeding mechanism is located below the limiting frame. The feeding mechanism includes a sliding frame and a linear drive module. The linear drive module drives the sliding frame to slide along the length of the aluminum strip. The sliding frame is provided with a pushing structure, which is used to push the bottom aluminum strip and provide support. A cutting mechanism is provided on the second platform. The cutting mechanism includes a frame, a power element and a cutting mold. The cutting mold includes an upper mold assembly and a lower mold assembly.

The lower die template is provided with a plurality of lower punch holes. The limiting structures are symmetrically arranged on both sides of the punch holes. The two limiting structures cooperate with the lower die template to limit the aluminum strip, so that the aluminum strip can only move along the length direction. The lower die template is provided with a stop block on the side of the aluminum strip being cut. The stop block slides through the lower die base and is connected to the second cylinder.

[0009] In a preferred embodiment of the aluminum strip cutting and punching equipment provided by the present invention, the lower template is provided with a first support block at the feeding end of the aluminum strip, and the lower template is provided with a second support block between two limiting structures. Both the first support block and the second support block are connected to the lower mold base by springs.

[0010] In a preferred embodiment of the aluminum strip cutting and punching equipment provided by the present invention, the upper mold assembly includes an upper mold base, an intermediate plate and a pressure plate. The intermediate plate is fixedly connected to the upper mold base, and the pressure plate is elastically limited to the intermediate plate. The intermediate plate is provided with a plurality of punching posts and punching blades. The punching posts are correspondingly arranged with the punching holes on the lower mold plate, and the punching blades are correspondingly arranged with the elastic support blocks.

[0011] In a preferred embodiment of the aluminum strip cutting and punching device provided by the present invention, the pressure plate is provided with an upper punch and a punching through groove, and the upper punch is provided with grooves on both sides that match the limiting structure. The pressure plate is in contact with the lower template, and the aluminum strip is pressed down between the two grooves.

[0012] In a preferred embodiment of the aluminum strip cutting and punching equipment provided by the present invention, the limiting mechanism includes a limiting frame, a first end plate structure, and a second end plate structure. Multiple sets of limiting frames are provided between the first end plate structure and the second end plate structure, and adjacent limiting frames are connected by connecting rods. The limiting frame includes symmetrically arranged L-frames and vertical plates. The vertical plates are fixed on the L-frames, and a space for placing aluminum strips is formed between the two vertical plates. A stop bar is fixed to the bottom of the two vertical plates, and the stop bar is used to support the aluminum strip. The first end plate structure and the second end plate structure limit the two ends of the aluminum strip.

[0013] As a preferred embodiment of the aluminum strip cutting and punching equipment provided by the present invention, the inner side of the vertical plate is provided with two sets of separating support structures, and the vertical plate is provided with a vertical groove. The separating support structure is placed in the vertical groove. The separating support structure is used to separate the stacked aluminum strips and avoid friction between the aluminum strips when the feeding mechanism pushes the bottom layer of aluminum strips.

[0014] In a preferred embodiment of the aluminum strip cutting and punching equipment provided by the present invention, the partition support structure includes a fixed frame and a first cylinder fixed at both ends of the fixed frame. The output end of the first cylinder is fixed with a mounting base. A support frame is fixed on the mounting base, and a protrusion is provided on the support frame. The protrusion is not located at the end of the support frame, and the height of the protrusion is not greater than the thickness of the aluminum strip.

[0015] In a preferred embodiment of the aluminum strip cutting and punching device provided by the present invention, the pushing structure includes a fixed frame, with a first cylinder installed at both ends of the fixed frame. A mounting base is fixed at the output end of the first cylinder, and a support frame is fixed on the mounting base. A protrusion is provided on the support frame, and the thickness of the protrusion is not greater than the thickness of the aluminum strip.

[0016] In a preferred embodiment of the aluminum strip cutting and punching device provided by the present invention, the first end plate structure is provided with a first through groove for the support frame to pass through, and the second end plate structure is provided with a second through groove for the aluminum strip to pass through.

[0017] Compared with the prior art, the present invention has the following advantages: By setting a limiting mechanism on the first platform, the stacked aluminum strips are suspended and positioned within the limiting frame. A separating support structure further separates the stacked aluminum strips one by one, avoiding direct contact and friction between them and effectively preventing scratches on the surface. A linear drive module drives a sliding frame to slide along the length of the aluminum strips. The pushing structure on the sliding frame precisely pushes the bottommost aluminum strip and provides support, thus achieving an automatic feeding method that separates and pushes the bottommost aluminum strip one by one from the stacked state. The system utilizes the weight of the aluminum strip itself to achieve automatic feeding, which greatly simplifies the overall structure and significantly reduces equipment costs. At the same time, the pushing structure lifts and pushes the aluminum strip from below, providing stable support during the pushing process and avoiding the problem of the aluminum strip easily shifting. This significantly improves the stability and reliability of feeding. The aluminum strip pushed out by the limiting mechanism can directly and accurately enter the processing station of the cutting mold. During the cutting process, the limiting structure of the lower mold component precisely limits the aluminum strip, thereby realizing the full automation and high-precision processing of the aluminum strip from feeding and delivery to cutting.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0023] 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 further defined and explained in subsequent figures.

[0024] Please refer to Figure 1A cutting and punching equipment for aluminum strips is provided, which includes a frame 1. The top surface of the frame 1 is provided with a first table 11 and a second table 12. A PLC control system is arranged inside the frame 1 for automatic control of the overall electric structure. A control panel is also fixed on the frame 1. The PLC control system is electrically connected to a linear drive module 82, a first cylinder 832, a second cylinder 725, a power element 6, and an infrared detection sensor 10, respectively, for controlling the feeding action of the feeding mechanism 8 and the timing of the cutting action of the cutting mechanism, so as to realize fully automated continuous processing.

[0025] like Figures 1-3 As shown, a limiting mechanism is provided on the first platform 11 to limit the placement of stacked aluminum strips 9. Below the limiting mechanism is a feeding mechanism 8, which includes a sliding frame 81 and a linear drive module 82. The linear drive module 82 is fixed on the first platform 11 by a horizontal frame and adopts a belt drive structure. The linear drive module 82 drives the sliding frame 81 to slide along the length direction of the aluminum strips 9. Guide rails are provided on both sides of the sliding frame 81 to ensure that the sliding frame 81 moves in a straight line. A guide groove structure with sliding fit is provided between the guide rail and the sliding frame 81, so that the sliding frame 81 can slide back and forth smoothly under the drive of the linear drive module 82. A pushing structure 83 is provided on the sliding frame 81. The pushing structure 83 is located directly below the stacked aluminum strips 9. The pushing structure 83 pushes the bottom aluminum strip 9 out of the aluminum strip stack and provides support during the pushing process.

[0026] like Figure 1 , Figure 7As shown, a cutting mechanism is provided on the second platform 12. The cutting mechanism includes a frame 5, a power element 6, and a cutting mold 7. The cutting mold 7 includes an upper mold assembly 71 and a lower mold assembly 72. The lower mold assembly 72 is fixed on the frame 5. The upper mold assembly 71 slides vertically within the frame 5 via guide rods 51. Four guide rods 51 are provided and distributed at the four corners of the frame 5 to ensure the verticality and stability of the lifting and lowering movement of the upper mold assembly 71. The power element 6 adopts a hydraulic cylinder or pneumatic cylinder structure. The power element 6 is fixed on the top of the frame 5, and the output end of the power element 6 is fixedly connected to the upper mold assembly 71. The power element 6 drives the upper mold assembly 71 to lift and lower. A limiting structure 73 is provided on the lower mold assembly 72. The limiting structure 73 adopts a symmetrically arranged pressure strip structure. The limiting structure 73 limits the aluminum strip 9, ensuring that the aluminum strip 9 can only move along the length direction. There is a small gap between the inner side wall of the limiting structure 73 and the two side walls of the aluminum strip 9 in the width direction. This ensures that the aluminum strip 9 can slide freely along the length direction and avoids the aluminum strip 9 moving around in the width direction. The aluminum strip cutting channel entrance formed by the two limiting structures 73 is set correspondingly to the pushing structure 83. When the pushing structure 83 pushes the aluminum strip 9, the aluminum strip 9 is pushed out from the limiting mechanism and directly enters the aluminum strip cutting channel formed by the two limiting structures 73. This achieves seamless connection between the feeding channel and the cutting channel, ensuring that the aluminum strip 9 will not deviate during the transfer process.

[0027] Furthermore, such as Figures 2-6 As shown, the limiting mechanism includes a limiting frame 2, a first end plate structure 3, and a second end plate structure 4. The first end plate structure 3 is located at the end of the feeding mechanism 8 away from the cutting mechanism, and the second end plate structure 4 is located at the end of the feeding mechanism 8 close to the cutting mechanism. The second end plate structure 4 is fixed on the upright frame 5. Multiple sets of limiting frames 2 are provided between the first end plate structure 3 and the second end plate structure 4, and adjacent limiting frames 2 are connected by connecting rods 21. In this embodiment, three sets of limiting frames 2 are provided. The limiting frame 2 includes symmetrically arranged L-frames 22 and vertical plates 23. The vertical plates 23 are suspended and fixed on the L-frames 22. The vertical plates 23 and the L-frames 22 are connected. The vertical parts of 2 are detachably fixedly connected by bolts, which makes it easy to adjust the spacing between the two vertical plates 23 according to the different widths of aluminum strips 9. The space between the two vertical plates 23 is formed to place the aluminum strips 9. The bottom of the two vertical plates 23 is fixed with a baffle 24, which is used to support the aluminum strips 9. The upper surface of the baffle 24 is a horizontal support surface. The bottom surface of the bottom layer of aluminum strips 9 is attached to the upper surface of the baffle 24. The baffle 24 bears the weight of all the stacked aluminum strips 9. The first end plate structure 3 and the second end plate structure 4 limit the two ends of the aluminum strips 9. There is a gap between the two baffles 24 to facilitate the passage of the pushing structure 83.

[0028] Specifically, such as Figures 2-4As shown, the pushing structure 83 includes a fixed frame 831 and a first cylinder 832 fixed at both ends of the fixed frame 831. A mounting base 833 is fixed to the output end of the first cylinder 832. A support frame 834 is fixed to the mounting base 833, and a protrusion 835 is provided on the support frame 834. The protrusion 835 is not located at the end of the support frame 834, but is positioned close to the end of the support frame 834, so that after the support frame 834 passes through the first through groove 31, the protrusion 835 is just positioned at the limiting mechanism. The internal structure can fit against the end face of the bottom aluminum strip 9, and the height of the protrusion 835 is not greater than the thickness of the aluminum strip 9, ensuring that only one aluminum strip 9 is pushed at a time. When multiple aluminum strips 9 need to be pushed, the support frame 834 with the corresponding height of the protrusion 835 can be replaced. The height of the protrusion 835 is adapted to the total thickness of the aluminum strips 9 to be pushed. In order to facilitate the pushing of aluminum strips 9, a first through groove 31 for the support frame 834 to pass through is provided on the first end plate structure 3, and a second end plate structure 4 is provided for... As the aluminum strip 9 passes through the second through slot 41, the sliding frame 81 moves the pushing structure 83 to the leftmost position when the aluminum strip 9 is pushed, causing the left support frame 834 to pass through the first through slot 31. Then, the first cylinder 832 drives the support frame 834 to rise, so that the top surface of the support frame 834 is in contact with the bottom aluminum strip 9. The sliding frame 81 moves the pushing structure 83 to the right, and the protrusion 835 on the left support frame 834 is in contact with the left end face of the bottom aluminum strip 9. When it continues to move to the right, it pushes... The bottom aluminum strip 9 passes through the second through groove 41 and enters the cutting mold 7 for cutting. The second through groove 41 ensures that only one aluminum strip 9 can pass through at a time and also ensures that the support frame 834 passes through the bottom of the second through groove 41, thereby ensuring that the aluminum strip 9 can be pushed into place. The height of the second through groove 41 is adapted to the thickness of a single aluminum strip 9, and the width of the second through groove 41 is adapted to the width of the aluminum strip 9, so that the second through groove 41 has a dual function of guiding and limiting the aluminum strip 9 when it passes through.

[0029] Of course, for some thinner aluminum strips 9, the cutting die 7 can cut two or more at a time, and the pushing structure 83 can push two or more aluminum strips 9 at a time. The height of the matching protrusion 835 also corresponds to the total thickness of the pushed aluminum strips 9.

[0030] like Figure 5 , Figure 6As shown, friction occurs between aluminum strips 9 during the pushing process, causing damage to their surface. To address this, two sets of separating support structures 25 are provided on the inner side of the vertical plate 23, and the vertical plate 23 has vertical grooves 26. The separating support structures 25 are placed within the vertical grooves 26. The separating support structures 25 are used to separate the stacked aluminum strips 9, preventing friction between the aluminum strips 9 when the feeding mechanism 8 pushes the bottom layer of aluminum strips 9, thus avoiding damage to the surface of the aluminum strips 9. The separating support structures 25 are arranged vertically on the inner side of the vertical plate 23, and their height range covers the vertical distribution area of ​​all stacked aluminum strips 9, ensuring that each stacked aluminum strip 9 can be effectively separated.

[0031] Specifically, such as Figure 6 As shown, the partition support structure 25 includes a closed-loop track 251. Drive shafts 252 are located at both ends of the closed-loop track 251. Several equally spaced support strips 253 are arranged on the closed-loop track 251. The distance between two adjacent support strips 253 is greater than the thickness of the aluminum strip 9. The drive shafts 252 at both ends of the closed-loop track 251 are axially connected to the two ends of the vertical groove 26. When force is applied to one side, the force-affected side of the closed-loop track 251 can automatically move downwards. The drive shafts 252 are rotatably mounted on both ends of the vertical groove 26. The closed-loop track 251 is fitted onto the two drive shafts 252 to form a ring-shaped rotating structure. The side of the closed-loop track 251 closer to the aluminum strip 9 is the load-bearing side, and the side farther from the aluminum strip 9 is the rotating side. The support strips 253 are rubber strips and are attached to the closed-loop track. The belt 251 is an integral structure. When the bottom surface of the aluminum strip 9 is attached to the stop strip 24, the top two sides of the aluminum strip 9 are attached to the support strip 253 on the inner side of the closed-loop track 251. This restricts the rotation of the closed-loop track 251 and keeps the support strip 253 at the current height position to provide stable support for the aluminum strip 9. After the aluminum strip 9 is pushed out of the limiting mechanism by the pushing structure 83, the support strip 253 is no longer under force. Under the pressure of the gravity of the upper aluminum strip 9, the closed-loop track 251 on the two vertical plates 23 rotates automatically, causing the second-to-last layer of aluminum strip 9 to fall onto the stop strip 24. This operation is repeated to achieve automatic replenishment of material after pushing the aluminum strip 9 and to separate two adjacent aluminum strips 9, avoiding surface damage caused by friction between the aluminum strips 9 during the pushing process.

[0032] Furthermore, the aluminum strip 9 does not contact or apply pressure to the inner side of the closed-loop track 251 on both sides in the width direction, ensuring that the aluminum strip 9 can fall smoothly downwards.

[0033] like Figures 7-13As shown, the lower mold assembly 72 includes a lower mold base 721 and a lower mold template 722. The lower mold template 722 has several lower punches 723. The number and position of the punches are determined according to the structure of the aluminum strip 9 to be cut. Limiting structures 73 are symmetrically arranged on both sides of the lower punches 723. The two limiting structures 73 cooperate with the lower mold template 722 to limit the aluminum strip 9, so that the aluminum strip 9 can only move along the length direction. The lower mold template 722 has a stop 724 on the cutting side of the aluminum strip 9. The stop 724 slides through the lower mold base 721. After 21, it connects to the second cylinder 725. When the pushing structure 83 pushes the aluminum strip 9, the second cylinder 725 drives the stop block 724 to move upward, so that the stop block 724 can position the aluminum strip 9 in the sliding direction to ensure the punching accuracy. The stop block 724 achieves the limiting function. At the same time, a first support block 726 is provided at the feeding end of the lower template 722 located on the aluminum strip 9, and a second support block 727 is provided between the two limiting structures 73. Both the first support block 726 and the second support block 727 are connected to the upper template 722. Spring 728 is connected to the lower mold base 721. Spring 728 is a compression spring, one end of which is fixed in the spring mounting hole on the lower mold base 721, and the other end is fixedly connected to the bottom surface of the first support block 726 or the second support block 727. In its natural state, spring 728 pushes the first support block 726 and the second support block 727 upward, so that the upper surface of the first support block 726 and the second support block 727 is flush with or slightly higher than the upper surface of the lower mold plate 722. 726 is located at the punching position and can act as a buffer when punching and cutting the aluminum strip 9. Together with the second support block 727, it can lift the aluminum strip 9 upward under the action of elasticity to prevent the aluminum strip 9 from shaking and play a role in shock absorption and stability. In addition, slots are also opened at the corresponding positions of the lower die base 721 and the lower punch hole 723 to facilitate the collection of the punched waste. At the same time, the lower die plate 722 is set as a sloping groove structure at the discharge end, and a guide groove is connected at the sloping groove structure to directly discharge the cut and punched aluminum strip 9.

[0034] Furthermore, such as Figures 7-13As shown, the upper mold assembly 71 includes an upper mold base 711, an intermediate plate 712, and a pressure plate 713. The intermediate plate 712 is fixedly connected to the upper mold base 711, and the pressure plate 713 is elastically limited to the intermediate plate 712. The pressure plate 713 and the intermediate plate 712 are connected by a guide post 714 and a return spring 715. One end of the guide post 714 is fixed to the lower surface of the intermediate plate 712, and the other end slides through a guide hole on the pressure plate 713, so that the pressure plate 713 maintains a predetermined distance from the intermediate plate 712 in its natural state. When subjected to external force, the pressure plate 713 can move upward relative to the intermediate plate 712 and compress the return spring 715. The intermediate plate 712 is provided with a plurality of punching posts 716 and punching cutters 717. The punching posts 716 and the... The lower template 722 has corresponding lower punch holes 723, and the punching cutter 717 is correspondingly set with the second support block 727. The pressure plate 713 has upper punch holes 718 and punching slots 719, and on both sides of the upper punch holes 718 are slots 7110 that match the limiting structure 73. The pressure plate 713 fits against the lower template 722, and the aluminum strip 9 is pressed down between the two slots 7110. The position and number of the upper punch holes 718 correspond one-to-one with the punching posts 716, and the position and shape of the punching slots 719 match the punching cutter 717. The slots 7110 and the limiting structure 73 are in concave-convex fit, achieving precise positioning between the pressure plate 713 and the lower template 722 when the mold is closed. Specifically, the intermediate plate 712 and the pressure plate 713 are connected by a composite... The spring 715 and guide post 714 are connected, so that when the upper die assembly 71 is pressed down, the pressure plate 713 first fits against the lower die plate 722 and presses down the aluminum strip 9. As the upper die assembly 71 continues to press down, the punching post 716 and the cutting blade 717 extend from the upper punch 718 and the punching slot 719 to punch the aluminum strip 9 on the lower die assembly 72, achieving the cutting and punching of the aluminum strip 9. After passing through the upper punch 718, the punching post 716 continues to punch downwards into the lower punch 723, pushing the punching waste into the corresponding slot in the lower die base 721. After passing through the punching slot 719, the cutting blade 717 punches downwards to cut the aluminum strip 9 above the second support block 727. Under the action of the cutting blade 717, the second support block 727 overcomes the elastic force of the spring 728 and moves downwards, providing... The punching blade 717 provides clearance to ensure that the aluminum strip 9 is completely cut off. Infrared detection sensors 10 are also provided on both sides of the upper mold assembly 71 and the lower mold assembly 72. The infrared detection sensor 10 includes an infrared transmitter and an infrared receiver arranged opposite each other. When the upper mold assembly 71 is in the mold closing position, the infrared receiver does not receive the signal from the infrared transmitter. When the upper mold assembly 71 leaves the lower mold assembly 72, the infrared receiver receives the signal from the infrared transmitter. The control system determines that the upper mold assembly 71 has been reset based on this. Only after the infrared detection sensor 10 detects that the upper mold assembly 71 has left the lower mold assembly 72 will the pushing structure 83 push the aluminum strip 9 to achieve safety interlock and avoid collision between the pushing structure 83 and the upper mold assembly 71.

[0035] The working principle of the aluminum strip cutting and punching equipment provided by this invention: In the initial state, the operator stacks multiple aluminum strips 9 vertically between the two vertical plates 23 of the limiting mechanism. The bottom surface of the lowest aluminum strip 9 is in contact with the upper surface of the stop strip 24. Adjacent aluminum strips 9 are separated by the support strips 253 of the separating support structure 25, and each aluminum strip 9 is in a suspended stacked state. The protrusion 835 of the pushing structure 83 is in the initial position, the stop block 724 is in the descending position, and the upper mold assembly 71 is in the ascending position.

[0036] During feeding, the PLC control system activates the linear drive module 82, causing the sliding frame 81 to move along the guide rail away from the cutting mechanism to the leftmost position. This allows the left support frame 834 to pass through the first through slot 31 on the first end plate structure 3 and extend into the limiting mechanism. Subsequently, the PLC control system activates the first cylinder 832, driving the mounting base 833 and the support frame 834 to move upwards, causing the protrusion 835 on the support frame 834 to rise until its top surface is in contact with the lower surface of the bottom aluminum strip 9. Then, the PLC control system activates the linear drive module 82 in the opposite direction, driving the sliding frame 81 to move closer to the cutting mechanism. After the protrusion 835 on the support frame 834 is in contact with the left end face of the bottom aluminum strip 9, it pushes the bottom aluminum strip 9 along its length. The aluminum strip 9 passes through the second through slot 41 on the second end plate structure 4 and is pushed onto the lower template 722 of the cutting mechanism, entering the aluminum strip cutting channel formed by the two limiting structures 73. During this process, the second through groove 41 guides and limits the aluminum strip 9, ensuring that the aluminum strip 9 enters the cutting mold 7 in the correct posture.

[0037] During positioning, when the aluminum strip 9 is pushed to the predetermined position, the PLC control system controls the second cylinder 725 to move, driving the stop block 724 to move upward. The upper end face of the stop block 724 extends out of the upper surface of the lower template 722, and the end of the aluminum strip 9 abuts against the positioning surface of the stop block 724, thereby achieving precise positioning of the aluminum strip 9 along its length.

[0038] During cutting, the PLC control system controls the power element 6 to move, driving the upper mold assembly 71 to move downward along the guide rod 51. The pressure plate 713 first fits against the lower template 722. The grooves 7110 on the pressure plate 713 and the limiting structure 73 on the lower template 722 cooperate to achieve precise alignment. The part between the two grooves 7110 on the pressure plate 713 presses the aluminum strip 9 tightly onto the lower template 722. Power component 6 continues to output power, and intermediate plate 712 continues to move downward against the elastic force of return spring 715. Punching post 716 passes through upper punch hole 718 on pressure plate 713 and punches aluminum strip 9. Punching waste falls through lower punch hole 723 on lower template 722 into slot in lower mold base 721 for collection. At the same time, punching cutter 717 passes through punching slot 719 on pressure plate 713 and cuts aluminum strip 9. Second support block 727 retracts downward against the elastic force of spring 728 under the pressure of punching cutter 717, providing clearance for punching cutter 717. Punching and cutting of aluminum strip 9 are completed simultaneously in one mold closing action.

[0039] During reset, the PLC control system controls the power element 6 to reverse its action, driving the upper mold assembly 71 to reset upwards. The pressure plate 713, under the action of the reset spring 715, returns to its initial distance from the intermediate plate 712. The second cylinder 725 is then controlled to reverse its action, driving the stop block 724 to reset downwards to below the lower mold plate 722. The cut and punched aluminum strip 9 slides through the inclined groove structure at the discharge end of the lower mold plate 722 into the guide chute for discharge.

[0040] Automatic feeding: After the bottom aluminum strip 9 is pushed out, the support strip 253 corresponding to the original position of the aluminum strip 9 is no longer under force. The upper aluminum strip 9 moves downward under the action of gravity, applying pressure to the support strip 253 below it, driving the closed-loop track 251 to rotate around the drive shaft 252, so that the upper aluminum strip 9 moves downward synchronously with the support strip 253 until the aluminum strip 9 falls onto the stop strip 24 and becomes the new bottom aluminum strip 9, realizing automatic feeding.

[0041] Safety interlock: The infrared detection sensor 10 detects the position of the upper mold assembly 71 in real time. Only when the infrared detection sensor 10 detects that the upper mold assembly 71 has completely left the lower mold assembly 72 will the PLC control system allow the feeding mechanism 8 to perform the next pushing action, ensuring that the pushing structure 83 does not interfere with or collide with the upper mold assembly 71.

[0042] Repeat the above feeding, positioning, cutting, resetting and automatic replenishment steps to achieve continuous automated processing of aluminum strip 9.
