Description

Technical Field

[0001] The present invention relates to the technical field of plate cutting and processing, and in particular to a punching device and a processing method for processing building aluminum alloy templates. Background Art

[0002] In the construction industry, aluminum alloy formwork has gradually become the mainstream formwork material due to its advantages such as light weight, high strength, and reusability. However, the processing accuracy of aluminum alloy formwork directly affects the quality and efficiency of construction, and the drilling process is a key step in formwork processing. At present, the following problems are common when cutting and drilling traditional architectural aluminum alloy formwork: insufficient positioning accuracy. Most equipment uses manual or semi-automatic methods to adjust the drilling position and the plate clamping point, which can easily lead to hole position deviation due to human operation errors. Especially in the multi-hole processing of complex formwork, the cumulative error significantly affects the template splicing accuracy; poor clamping stability. Existing devices mostly rely on single mechanical clamping or simple pneumatic clamping, which cannot effectively suppress vibration during drilling. The plate is prone to displacement or deformation, resulting in hole size deviation, rough surface, and high scrap rate. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention solves the technical problems thereof by adopting the following technical solutions: a punching device for processing architectural aluminum alloy formwork, comprising: a processing table, the top end of the processing table is fixedly connected to a fixed frame, a driving frame is provided on the outside of the processing table, a cutting device is provided on the top of the driving frame, a clamping device is slidably connected to the outer wall of the processing table, a supporting device is provided on the inside of the fixed frame, and a fixing device is provided on the top end of the supporting device; the clamping device comprises a mounting frame, the top end of the mounting frame is fixedly connected to a connecting block, an upper moving rod is provided on the outside of the mounting frame, and a lower moving rod is provided on the bottom end of the upper moving rod. The outer walls of the upper moving rod and the lower moving rod are symmetrically fixedly connected to the sliding rod, the bottom end of the sliding rod is fixedly connected to the mounting block, and the outer wall of the mounting block is fixedly connected to the contact assembly; the fixing device includes a fixing block, the outer wall of the fixing block is fixedly connected to the friction pad, the outside of the fixing block is provided with a moving plate, the outer wall of the moving plate is symmetrically fixedly connected to the push rod, and the outer wall of the fixing block is fixedly connected to the air intake cylinder; the supporting device includes a supporting block, the outer wall of the support block is rotatably connected to the hinged rod, the bottom end of the support block is provided with an air outlet, the outer wall of the air outlet is fixedly connected to the air intake pipe, and the outer wall of the air intake pipe is fixedly connected to the bellows.

[0004] The present invention is further configured such that the outer wall of the mounting frame is slidably connected to the outer wall of the processing table, the outer wall of the connecting block is fixedly connected to the outer wall of the driving frame, and the outer wall of the slide rod is slidably connected to the inner wall of the mounting frame. The driving frame serves as the core of movement and is driven by an external power source such as a motor or a cylinder to achieve horizontal or vertical movement, and a cutting device such as a drill bit mounted on its top is moved to a target drilling position accordingly. The outer wall of the driving frame is fixedly connected to the connecting block of the clamping device, so that when the driving frame moves, it simultaneously drives the clamping device to slide along the outer wall of the processing table, ensuring that the clamping position is synchronously aligned with the drilling position.

[0005] The present invention further provides that the outer wall of the mounting frame is rotatably connected to a handle, and the outer wall of the handle is symmetrically rotatably connected to a pull rod, and the ends of the two pull rods, remote from the handle, are rotatably connected to the outer walls of the upper and lower movable rods, respectively. The handle is driven to rotate by an external drive motor, thereby driving the symmetrically arranged pull rods to push and pull the upper and lower movable rods, and the upper and lower movable rods drive the mounting block and the contact assembly toward the aluminum alloy plate.

[0006] The present invention further provides that the contact assembly includes a U-shaped frame, the inner walls of which are slidably connected to limit rods at the four corners of the U-shaped frame, the bottom ends of which are fixedly connected to a pressure plate, the inner wall of which is rotatably connected to a rotating wheel, the outer wall of which is fixedly connected to a push spring, and the outer wall of the U-shaped frame is fixedly connected to the outer wall of the mounting frame. The pressure plate in the contact assembly elastically presses against the sheet material via the push spring, the rotating wheel reduces frictional resistance during clamping, and the rotating handle automatically clamps the upper and lower surfaces of the sheet material in the area to be drilled, forming a localized rigid support to prevent the sheet material from shaking during drilling.

[0007] The present invention further comprises an external tube slidably connected to the inner wall of the air intake cylinder, a limit frame fixedly connected to the outer wall of the external tube, a block slidably connected to the inner wall of the air intake cylinder, a flow hole formed in the wall of the block, an air supply pipe fixedly connected to the outer wall of the air intake cylinder, and a return spring fixedly connected to the outer wall of the movable plate. An external cylinder injects compressed air into the external tube of the fixture. The air pressure moves the block within the air intake cylinder, which in turn drives the fixed block to slide along the inner wall of the fixed frame until the friction pads of the movable plate contact the ends of the aluminum alloy plate.

[0008] The present invention further provides that the outer wall of the fixed block is slidably connected to the inner wall of the fixed frame, the end of the limit frame remote from the external tube is fixedly connected to the outer wall of the fixed frame, the inner wall of the fixed block is slidably connected to the outer wall of the push rod, and the end of the return spring remote from the movable plate is fixedly connected to the inner wall of the fixed block. The return spring provides a reverse elastic force to ensure that the fixed block returns to its original position after the air pressure is removed; the flow hole of the block gradually aligns with the air pipe during movement, enabling subsequent transmission of air pressure; when the movable plate moves, the push rod synchronously pushes the block, and when the flow hole is connected to the air pipe, compressed air enters the bellows through the air pipe, triggering the suspension action of the support device.

[0009] The present invention is further configured such that the outer wall of the support block is slidably connected to the inner wall of the fixed frame, the end of the hinged rod remote from the support block is rotatably connected to the outer wall of the fixed frame, the outer wall of the outlet tube is fixedly connected to the outer wall of the fixed frame, and the end of the bellows remote from the air inlet pipe is fixedly connected to the outer wall of the air supply pipe. The air pressure within the bellows is transmitted to the outlet tube via the air inlet pipe, pushing the plug to move. The plug, through the mounting rod, pulls the support block to overcome the support force of the hinged rod and retracts toward the center of the fixed frame, leaving the aluminum alloy plate suspended below, facilitating the removal of debris during drilling and preventing plate deformation.

[0010] The present invention is further configured such that the inner wall of the punching bag is slidably connected to a leather plug, the outer wall of the leather plug is fixedly connected to a mounting rod, the outer wall of the mounting rod is slidably connected to a slide, the outer wall of the slide is fixedly connected to a tension spring, the other end of the tension spring is fixedly connected to the outer wall of the leather plug, and the end of the mounting rod away from the slide is fixedly connected to the outer wall of the support block.

[0011] A punching method for processing building aluminum alloy templates, comprising the following steps: Step 1: Place the aluminum alloy plate to be processed on the supporting device on the fixed frame, and support the aluminum alloy plate to be processed by multiple supporting blocks; Step 2: Inject air into the external pipe in the fixing device through the external cylinder, so that the air inlet cylinder moves on the fixing frame until the movable plate contacts the two ends of the aluminum alloy plate to fix it, and until the aluminum alloy plate is clamped and fixed by the friction pad; Step 3: By moving the movable plate, the push rod pushes the blocking block to move, and air can enter the bellows through the circulation hole, causing the plug to move, so that the mounting rod pulls the support block to move and contract, making the aluminum alloy plate suspended; Step 4. At this time, the dynamic movement of the driving frame drives the cutting device to move to the required drilling position, and drives the clamping device to move. The external motor drives the handle to rotate, so that the contact component clamps the upper and lower ends of the aluminum alloy plate where the drilling is required, and cuts a hole in the aluminum alloy plate through the rotation of the cutting device.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention ensures the correspondence between the drilling position and the clamping position by arranging a synchronous linkage between the driving frame and the clamping device. During the drilling process, the clamping device can dynamically follow the movement of the cutting device to achieve real-time positioning and clamping of the area to be drilled in the aluminum alloy plate, avoiding errors caused by manual adjustment and improving the processing efficiency of the drilling position.

[0013] 2. This invention utilizes a fixture that uses a pneumatic system to securely clamp the sheet at both ends. This, combined with a friction pad, increases friction and prevents sheet displacement during processing. Furthermore, the clamping device provides localized rigid support in the drilling area. The spring-loaded contact between the spring and the rotating wheel stabilizes the sheet while preventing surface damage caused by excessive clamping. This dual clamping mechanism effectively suppresses vibration and deformation during drilling, reducing scrap.

[0014] 3. This invention utilizes pneumatic linkage between the support and fixtures to automatically suspend the central region of the aluminum alloy plate after it is secured. This design not only facilitates the free fall of drilling debris, minimizing the impact of debris accumulation on machining accuracy, but also prevents interference between the support structure and the drill bit, reducing the risk of equipment failure. Furthermore, the suspended state provides more uniform force on the plate, further ensuring stability during the drilling process.

[0015] 4. The present invention realizes the automated control of operations such as plate fixing, support contraction, and clamping positioning by integrating the pneumatic system with the mechanical structure. The operator only needs to complete the loading and starting instructions, and the equipment can complete the punching task according to the preset process, reducing the manual intervention links and labor intensity, while improving the continuity and consistency of production, making it suitable for large-scale industrial production.

[0027] A punching method for processing building aluminum alloy templates, comprising the following steps: Step 1: Place the aluminum alloy plate to be processed on the supporting device 7 on the fixed frame 5, and support the aluminum alloy plate to be processed by a plurality of supporting blocks 71; Step 2: Inject air into the external pipe 64 in the fixing device 6 through the external cylinder, so that the air inlet cylinder 66 moves on the fixing frame 5 until the movable plate 63 contacts the two ends of the aluminum alloy plate to fix it, and until the aluminum alloy plate is clamped and fixed by the friction pad 62; Step 3: By moving the movable plate 63, the push rod 69 pushes the blocking block 67 to move, and air passes through the circulation hole 611 and enters the bellows 74, causing the plug 77 to move, so that the mounting rod 73 pulls the support block 71 to move and contract, leaving the aluminum alloy plate suspended in the air; Step 4. At this time, the dynamic movement of the driving frame 3 drives the cutting device 4 to move to the required drilling position, and drives the clamping device 2 to move. The external motor drives the handle 24 to rotate, so that the contact component 29 clamps the upper and lower ends of the aluminum alloy plate where the hole is required to be drilled, and cuts a hole in the aluminum alloy plate through the rotation of the cutting device 4.

[0028] Working principle: When in use, the driving frame 3 acts as the core of movement and is moved horizontally or vertically by an external power source such as a motor or a cylinder. The cutting device 4 such as a drill bit mounted on the top of the driving frame moves to the target drilling position accordingly. The outer wall of the driving frame 3 is fixedly connected to the connecting block 22 of the clamping device 2. Therefore, when the driving frame moves, it will simultaneously drive the clamping device 2 to slide along the outer wall of the processing table 1, ensuring that the clamping position is synchronously aligned with the drilling position. The clamping device 2 drives the handle 24 to rotate through the driving motor, driving the symmetrically arranged pull rods 25 to push and pull the upper moving rod 23 and the lower moving rod 26. The upper moving rod 23 and the lower moving rod 26 drive the mounting block 28 and the contact assembly 29 to approach the aluminum alloy plate. The pressure plate 294 in the contact assembly 29 elastically presses against the plate through the push spring 293. The rotating wheel 295 can reduce the friction resistance during clamping. At the same time, the limit rod 292 ensures the vertical movement of the pressure plate to achieve stable clamping. An external air cylinder injects compressed air into the external pipe 64 of the fixing device 6. The air pressure pushes the block 67 in the air inlet cylinder 66 to move, thereby driving the fixing block 61 to slide along the inner wall of the fixing frame 5 until the friction pad 62 of the movable plate 63 contacts the two ends of the aluminum alloy plate. The return spring 610 provides a reverse elastic force to ensure that the fixing block returns to its original position after the air pressure is removed. The flow hole 611 of the block 67 gradually aligns with the air pipe 68 during the movement, realizing the subsequent transmission of air pressure. When the movable plate 63 moves, the push rod 69 synchronously pushes the block 67. When the flow hole 611 is connected to the air pipe 68, the compressed air enters the bellows 74 through the air pipe, triggering the suspension action of the support device. The air pressure within bellows 74 is transmitted through inlet pipe 75 to outlet pipe 76, pushing piston 77 to move. The piston, through mounting rod 73, pulls support block 71, overcoming the support force of hinged rod 72 and retracting toward the center of fixed frame 5, leaving the aluminum alloy plate suspended below. This facilitates the removal of debris during drilling and prevents plate deformation. A tension spring 78 connects the piston to slide 79. When the air pressure is removed, the piston is pulled back to its original position, and the support block, through the hinged rod, re-expands to support the plate. Initially, the support block 71 is unfolded by the hinge rod 72 to support the aluminum alloy plate. After the fixing device 6 clamps the plate, the air pressure drives the support block 71 to shrink, leaving only the edge clamped and fixed, and the middle area suspended to ensure that the plate is stable and there is no support interference during drilling. The driving frame 3 drives the cutting device 4 to move to the drilling position. At the same time, the contact component 29 of the clamping device 2 automatically clamps the upper and lower surfaces of the plate to be drilled through the turning handle 24 to form a local rigid support to avoid the plate from shaking during drilling. The cutting device 4 processes holes in the aluminum alloy plate through the vertical feed movement of the driving frame 3. The dynamic following of the clamping device 2 ensures stability during the drilling process.
