Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile punching equipment, in particular to aluminum profile punching equipment with a limiting function. Background Art

[0002] Punching refers to a punching method that separates the material in the blank from the blank with a closed outline to obtain a perforated part. It usually refers to punching various patterns on materials such as steel plates, leather, cloth, and wood to meet different needs. Punching products have different uses in various aspects such as industry, architecture, and design due to their good practicality and aesthetic characteristics. The punching equipment moves through a hydraulic mechanism to drive the punch to press down and shear, and uses the punch to form a hole of the corresponding shape on the surface of the material to complete the punching work.

[0003] The invention with publication number CN112719039A discloses a positioning punching device for processing aluminum profiles for doors and windows. The punching device can accurately adjust the punching depth according to a ruler to make the punching process more precise. According to the punching limit pointer, it can cooperate with the positioning punching device to accurately position and punch the aluminum profile.

[0004] However, when the above equipment is used to punch different types of profiles, such as plates, pipes and other profiles, there is a lack of effective limiting measures to ensure that different types of profiles can be effectively fixed during punching to prevent sliding deviation and thus causing the hole position to shift. In addition, there is a lack of recycling measures for waste generated by punching, so that the waste is scattered all over the ground during processing, affecting the processing environment. Therefore, in response to the above problems, an aluminum profile punching equipment with a limiting function is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an aluminum profile punching equipment with a limiting function. The aluminum profile punching equipment is provided with a buffering pressing and limiting mechanism with a buffering function. While pressing the profile to prevent sliding and deviation, it can also avoid deformation of the profile caused by excessive pressure. At the same time, the waste recovery box provided can recycle the punching waste falling from the waste mouth, avoid affecting the environment of the processing site, and reduce the burden of later cleaning. In particular, a recovery port baffle mechanism is provided at the bottom of the waste mouth, which is in a normally closed state, and can prevent dust or foreign matter from falling into the waste recovery box. When the equipment is running, the buffering pressing and limiting mechanism will drive the transmission part to move when it works, and press down the recovery port baffle mechanism to automatically open it, ensuring the smoothness of the overall operation of the equipment. The technical problems in the prior art that there is a lack of effective limiting measures, it is difficult to ensure that different types of profiles can be effectively fixed during punching, and there is a lack of synchronous waste recovery measures.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A punching device for aluminum profiles with a limiting function comprises a punching device body, which is used for punching profiles, and a waste opening and a matching hole are provided on a plate below the punch, a buffer pressing and limiting mechanism, which is arranged on the front side of the punching structure of the punching device body, a waste recovery box, which is arranged below the waste opening, and a recovery opening baffle mechanism, which is arranged below the waste opening and can cover the bottom of the waste opening; wherein, a transmission member is connected to the upper transmission of the buffer pressing and limiting mechanism, and when the buffer pressing and limiting mechanism is in operation, the bottom of the transmission member can pass through the matching hole and press against the recovery opening baffle mechanism to open it.

[0008] Through the above-mentioned structural form, the buffering pressing and limiting mechanism with a buffering function can not only press the profile to prevent sliding and deviation, but also avoid deformation of the profile caused by excessive pressure; the waste recovery box set at the same time can recycle the punching waste falling from the waste outlet, avoid affecting the environment of the processing site, and reduce the burden of subsequent cleaning; in particular, a recovery port baffle mechanism is provided at the bottom of the waste outlet, which is in a normally closed state, and can prevent dust or foreign matter from falling into the waste recovery box. When the equipment is running, the buffering pressing and limiting mechanism will drive the transmission part to move when it works, and press down the recovery port baffle mechanism to automatically open it, thereby ensuring the smoothness of the overall operation of the equipment.

[0009] In a possible implementation, the buffering, clamping and limiting mechanism includes a door frame, on which a hydraulic cylinder is mounted, and a connecting plate, which is slidably arranged between the door frames and fixedly connected to the output shaft of the hydraulic cylinder. In addition, guide rods and a pressure plate are slidably connected at both ends, and are fixedly connected to the bottom end of the guide rod; wherein a buffer spring is provided between the connecting plate and the pressure plate and is sleeved on the outside of the guide rod.

[0010] Through the above-mentioned structural form, the hydraulic cylinder can drive the connecting plate to move up and down, and then drive the pressure plate to move up and down. When the pressure plate contacts the profile, the hydraulic cylinder can transfer the pressure from the connecting plate to the buffer spring, and then transfer it to the pressure plate by the buffer spring, thereby pressing the profile to a limit position to prevent it from sliding and deviating. Moreover, since the buffer spring participates in the force transmission, it can buffer the pressure by its own deformation when the pressure is too large, thereby protecting the profile.

[0011] In a possible implementation, the fixing sleeve at the top end of the guide rod is provided with an anti-dropping piece, and when the anti-dropping piece is in close contact with the connecting plate, the buffer spring is still in a compressed rebound state.

[0012] Through the above-mentioned structural form, the effective connection between the connecting plate and the pressure plate can be ensured by preventing the plate from falling off, and the state of the buffer spring can ensure that it can provide a certain degree of force transmission when it is in the initial state.

[0013] In a possible implementation, guide grooves are provided on both sides of the door frame, and sliders are fixedly provided at both ends of the connecting plate and the pressure plate. The sliders are slidably set in the guide grooves. In addition, an anti-deviation sliding plate is fixedly provided on the slider and is in sliding contact with the inner side surface of the door frame.

[0014] Through the above-mentioned structural form, the slider can slide in the guide groove to constrain the connecting plate and the pressure plate to only move straight up and down along the guide groove, thereby facilitating the transmission of downward force. In addition, the anti-deviation slide can prevent the connecting plate and the pressure plate from deflecting during the sliding process through its own sliding contact with the door frame.

[0015] In one possible implementation, the waste recovery box includes an outer cover plate, which is installed at the front end of the punching equipment body, a herringbone guide plate, which is fixedly set on the outer cover plate, and the top tip is aligned with the middle of the waste opening, and a recovery drawer, which is slidably set in the outer cover plate, and a handle is fixedly connected to the outer end face.

[0016] Through the above-mentioned structural form, when waste falls through the waste opening, it will fall on the herringbone guide plate and be guided to the two sides of the recovery drawer by the herringbone guide plate, so that the waste can be distributed more evenly in the recovery drawer, thereby increasing the storage capacity of the recovery drawer in disguise.

[0017] In one possible implementation, the recovery port baffle mechanism includes a main baffle, which is rotatably arranged directly below the waste port and can completely cover the bottom of the waste port, and a transmission baffle, which is rotatably arranged directly below the matching hole; wherein the main baffle and the transmission baffle are fixedly connected by connecting the transmission plate.

[0018] Through the above-mentioned structural form, the main baffle can shield the waste opening to prevent foreign matter or dust from entering the waste recovery box through the waste opening. When the transmission baffle is rotated due to the downward pressure of the transmission member, the main baffle can be driven to rotate and open synchronously by connecting the transmission plate, so that the punched holes can enter the waste recovery box through the waste opening.

[0019] In a possible implementation, a return torsion spring is provided on the shaft sleeve on one side of the main baffle, one end of the return torsion spring is fixedly connected to the main baffle, and the other end of the return torsion spring is fixedly connected to the punching device body.

[0020] Through the above-mentioned structural form, the reset torsion spring can provide a reverse reset torque. When the transmission member leaves the transmission baffle, the reset torsion spring can provide a torque to reset the main baffle and continue to block the waste opening.

[0021] In one possible implementation, the transmission member includes a slide cylinder, which is fixedly mounted on the punching equipment body, a pressure rod, which is slidably arranged in the slide cylinder and is located directly above the matching hole, and an L-shaped connecting rod, one end of which is fixedly connected to the pressure rod and the other end of which is fixedly connected to the connecting plate.

[0022] Through the above-mentioned structural form, when the connecting plate moves, the pressure rod will be driven to slide up and down in the slide cylinder through the L-shaped connecting rod, so that the pressure rod slides out or inserts into the matching hole, which plays a role in pushing the transmission baffle to rotate and open the main baffle.

[0023] In a possible implementation, a notch is provided in the middle of the lower end surface of the pressure plate, in which a pipe pressing block is detachably installed, and notches are provided on both sides of the lower end surface of the pressure plate, in which a plate pressing sheet is detachably installed.

[0024] Through the above-mentioned structural form, by replacing different pipe pressing blocks, tubular profiles of different sizes and shapes can be pressed and fixed. The friction between the pressure plate and the plate profile can be increased by the plate pressing plate, thereby improving the pressing and fixing effect.

[0025] In a possible implementation, a spherical contact is connected to the bottom end of the pressure rod, and the spherical contact is threadedly connected to the pressure rod.

[0026] Through the above-mentioned structural form, the friction between the pressure rod and the transmission baffle can be significantly reduced, so that the pressure rod can smoothly push the transmission baffle to rotate when it is pressed down, and the connection form between the two can facilitate the replacement of the spherical contact when it is severely worn.

[0027] In summary, the present invention includes the following beneficial technical effects:

[0028] The buffer pressing and limiting mechanism with buffer function can play the role of pressing the profile to prevent sliding and deflection, and at the same time, it can also avoid deformation of the profile due to excessive pressure due to its buffering effect;

[0029] The waste recycling bin can recycle the punching waste dropped from the waste outlet, avoiding affecting the environment of the processing site and reducing the burden of later cleaning.

[0030] In particular, a recovery port baffle mechanism is provided at the bottom of the waste port, which is in a normally closed state to prevent dust or foreign matter from falling into the waste recovery box. When the equipment is running, the buffering and clamping limit mechanism will drive the transmission parts to move, and the recovery port baffle mechanism will be pressed down to open it automatically, ensuring the smoothness of the overall operation of the equipment.

[0039] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0040] like Figure 1 , Figure 3 , Figure 4 As shown, the present embodiment provides an aluminum profile punching device with a limiting function, comprising a punching device body 1, which is used for punching the profile, and a waste port 11 and a matching hole 12 are provided on the plate below the punch, a buffer pressing and limiting mechanism 2, which is arranged on the front side of the punching structure of the punching device body 1, and a waste recovery box 3, which is arranged below the waste port 11. Through the above-mentioned structural form, the buffer pressing and limiting mechanism 2 with a buffering function can not only press the profile to prevent sliding and deviation, but also avoid deformation of the profile due to excessive pressure.

[0041] In addition, a recovery port baffle mechanism 4 is provided below the waste port 11, which can cover the bottom of the waste port 11, wherein a transmission member 5 is connected to the buffer pressing limit mechanism 2, and when the buffer pressing limit mechanism 2 is in operation, the bottom of the transmission member 5 can pass through the matching hole 12 and press against the recovery port baffle mechanism 4 to open it. Through the above-mentioned structural form, the waste recovery box 3 set up can recycle the punching waste falling from the waste port 11, avoid affecting the environment of the processing site, and also reduce the burden of later cleaning; in particular, a recovery port baffle mechanism 4 is provided at the bottom of the waste port 11, which is in a normally closed state, and can prevent dust or foreign matter from falling into the waste recovery box 3, and when the equipment is running, the buffer pressing limit mechanism 2 will drive the transmission member 5 to move when it works, and press down the recovery port baffle mechanism 4 to automatically open it, thereby ensuring the smoothness of the overall operation of the equipment.

[0042] like Figure 2 As shown, the buffering, pressing and limiting mechanism 2 includes a door frame 21, on which a hydraulic cylinder 22 and a connecting plate 23 are mounted. The connecting plate 23 is slidably arranged between the door frames 21 and fixedly connected to the output shaft of the hydraulic cylinder 22. In addition, guide rods 24 and pressure plates 25 are slidably connected at both ends thereof and are fixedly connected to the bottom ends of the guide rods 24. A buffering spring 26 sleeved on the outside of the guide rods 24 is provided between the connecting plate 23 and the pressure plate 25. Through the above-mentioned structural form, the hydraulic cylinder 22 can drive the connecting plate 23 to move up and down, thereby driving the pressure plate 25 to move up and down. When the pressure plate 25 contacts the profile, the hydraulic cylinder 22 can transfer the pressure from the connecting plate 23 to the buffering spring 26, and then from the buffering spring 26 to the pressure plate 25, thereby pressing and limiting the profile to prevent it from sliding and deflecting. Moreover, since the buffering spring 26 participates in the force transmission, it can buffer the pressure by its own deformation when the pressure is too large, thereby protecting the profile.

[0043] Among them, the top fixed sleeve of the guide rod 24 is provided with an anti-slip sheet 241, and when the anti-slip sheet 241 is in close contact with the connecting plate 23, the buffer spring 26 is still in a compressed rebound state. Through the above-mentioned structural form, the anti-slip sheet 241 can ensure the effective connection between the connecting plate 23 and the pressure plate 25, and the state of the buffer spring 26 can ensure that when it is in the initial state, it can provide a certain degree of force transmission.

[0044] In addition, guide grooves 211 are opened on both sides of the door frame 21, and sliders 27 are fixedly set at both ends of the connecting plate 23 and the pressure plate 25. The slider 27 is slidably set in the guide groove 211. In addition, an anti-deviation slide 28 is fixedly sleeved on the slider 27 and is in sliding contact with the inner side surface of the door frame 21. Through the above-mentioned structural form, the slider 27 can slide in the guide groove 211 to constrain the connecting plate 23 and the pressure plate 25 to only go up and down along the guide groove 211, thereby facilitating the transmission of downward force. In addition, the anti-deviation slide 28 can prevent the connecting plate 23 and the pressure plate 25 from deflecting during the sliding process by sliding in contact with the door frame 21.

[0045] like Figure 3 As shown, the waste recovery box 3 includes an outer cover plate 31, which is installed at the front end of the punching equipment body 1, a herringbone guide plate 32, which is fixedly set on the outer cover plate 31, and the top tip is aligned with the middle of the waste port 11, and a recovery drawer 33, which is slidably set in the outer cover plate 31, and the outer end surface is fixedly connected with a handle 34. Through the above-mentioned structural form, when the waste falls through the waste port 11, it will fall on the herringbone guide plate 32, and the herringbone guide plate 32 will guide it to both sides of the recovery drawer 33, so that the waste can be distributed more evenly in the recovery drawer 33, thereby increasing the storage capacity of the recovery drawer 33 in disguise.

[0046] like Figure 4-Figure 5 As shown, the recovery port baffle mechanism 4 includes a main baffle 41, which is rotatably arranged just below the waste port 11 and can completely cover the bottom of the waste port 11, and a transmission baffle 42, which is rotatably arranged just below the matching hole 12; wherein, the main baffle 41 and the transmission baffle 42 are fixedly connected by connecting the transmission plate 44. Through the above-mentioned structural form, the main baffle 41 can shield the waste port 11 to prevent foreign matter or dust from entering the waste recovery box 3 through the waste port 11, and when the transmission baffle 42 is rotated by the downward pressure of the transmission member 5, it can synchronously drive the main baffle 41 to rotate and open by connecting the transmission plate 44, so that the punched hole can enter the waste recovery box 3 through the waste port 11.

[0047] Among them, a reset torsion spring 43 is provided on the shaft sleeve on one side of the main baffle 41, one end of the reset torsion spring 43 is fixedly connected to the main baffle 41, and the other end of the reset torsion spring 43 is fixedly connected to the punching equipment body 1. The reset torsion spring 43 can provide a reverse reset torque. When the transmission member 5 leaves the transmission baffle 42, the reset torsion spring 43 can provide a torque to reset the main baffle 41 and continue to block the waste port 11.

[0048] like Figure 4-Figure 5 As shown, the transmission member 5 includes a slide cylinder 51, which is fixedly mounted on the punching equipment body 1, a pressure rod 52, which is slidably arranged in the slide cylinder 51 and is located directly above the matching hole 12, and an L-shaped connecting rod 53, one end of which is fixedly connected to the pressure rod 52, and the other end is fixedly connected to the connecting plate 23. Through the above-mentioned structural form, when the connecting plate 23 moves, the pressure rod 52 will be driven to slide up and down in the slide cylinder 51 through the L-shaped connecting rod 53, so that the pressure rod 52 slides out or is inserted into the matching hole 12, which plays a role in pushing the transmission baffle 42 to rotate so that the main baffle 41 opens.

[0049] like Figure 2As shown, a notch is provided in the middle of the lower end surface of the pressure plate 25, in which a pipe pressing block 251 is detachably installed. Notches are provided on both sides of the lower end surface of the pressure plate 25, in which a plate pressing sheet 252 is detachably installed. Through the above-mentioned structural form, different pipe pressing blocks 251 can be replaced to clamp and fix tubular profiles of different sizes and shapes. The plate pressing sheet 252 can increase the friction between the pressure plate 25 and the plate profile, thereby improving the clamping and fixing effect.

[0050] like Figure 5 As shown, a spherical contact is connected to the bottom end of the pressure rod 52, and the spherical contact is threadedly connected to the pressure rod 52. Through the above-mentioned structural form, the friction between the pressure rod 52 and the transmission baffle 42 can be significantly reduced, so that the pressure rod 52 can smoothly push the transmission baffle 42 to rotate when it is pressed down, and the connection form between the two can facilitate the replacement of the spherical contact when it is severely worn.

[0051] The use principle and use process of the present invention:

[0052] The buffering, pressing and limiting mechanism 2 with a buffering function is provided, which can press the profile to prevent sliding and deviation, and while pressing the profile, due to its buffering effect, it can also avoid deformation of the profile due to excessive pressure. Specifically, the hydraulic cylinder 22 can drive the connecting plate 23 to move up and down, and then drive the pressing plate 25 to move up and down. When the pressing plate 25 contacts the profile, the hydraulic cylinder 22 can transfer the pressure from the connecting plate 23 to the buffer spring 26, and then from the buffer spring 26 to the pressing plate 25, so as to press and limit the profile to prevent it from sliding and deviation, and because the buffer spring 26 participates in the force transmission, it can buffer the pressure by its own deformation when the pressure is too large, thereby protecting the profile.

[0053] The waste recycling box 3 provided at the same time can recycle the punching waste falling from the waste port 11, avoid affecting the environment of the processing site, and also reduce the burden of later cleaning. Specifically, when the waste falls through the waste port 11, it will fall on the herringbone guide plate 32, and the herringbone guide plate 32 will guide it to the two sides of the recovery drawer 33, so that the waste can be distributed more evenly in the recovery drawer 33, thereby increasing the storage capacity of the recovery drawer 33 in disguise.

[0054] In particular, a recovery port baffle mechanism 4 is provided at the bottom of the waste port 11, which is in a normally closed state, thereby preventing dust or foreign matter from falling into the waste recovery box 3. When the equipment is running, the connecting plate 23 will drive the pressure rod 52 to slide up and down in the slide cylinder 51 through the L-shaped connecting rod 53, so that the pressure rod 52 slides out or inserts into the matching hole 12, thereby pushing the transmission baffle 42 to rotate so that the main baffle 41 opens, and the main baffle 41 is opened only for a short period of time after the punching is completed, allowing waste to pass through, which can effectively block dust and foreign matter, and the automatic opening and closing of the main baffle 41 can ensure the smoothness of the overall operation of the equipment.

[0055] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
