Description

Technical Field

[0001] The invention belongs to the technical field of aluminum single plate production, and relates to a punching device, in particular to a punching device for aluminum single plate production. Background Art

[0002] Architectural metal curtain wall decorative materials are a common product in the field of building curtain walls. The most commonly used metal curtain wall panels include aluminum veneer, aluminum-plastic composite panel and aluminum honeycomb panel. Among them, aluminum veneer generally uses 1.5-4.0mm thick AA3003 aluminum alloy plate, and building exterior walls generally use 2.5mm and 3.0mm thick aluminum alloy plates;

[0003] Aluminum veneers have a variety of shapes in actual applications. In order to reduce the weight of aluminum veneers and increase their aesthetics, holes are generally punched on the aluminum veneers. The punched aluminum veneers can effectively absorb noise. Therefore, punched aluminum veneers have a wide range of applications. When punching holes in aluminum veneers, the punching tool will produce a certain degree of wear. In order to ensure the quality of punching, it is necessary to stop the machine and replace the tool head with severe wear, thereby reducing the production efficiency of the aluminum veneer.

[0004] Based on this, we designed a punching device for aluminum veneer production. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a punching device for aluminum veneer production. The technical problem to be solved by the device is: how to replace the punching head without stopping the machine and improve the production efficiency of the aluminum veneer.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A punching device for aluminum single plate production comprises a centralized control box, a punching base is arranged at the front end of the centralized control box, a plurality of mold holes distributed at equal intervals are opened on the punching base, a gantry is fixed on the upper end of the punching base, vertical slide grooves are opened on both sides of the gantry, a pressing plate is slidably arranged between two vertical slide grooves, a plurality of hydraulic cylinders distributed at equal intervals are fixed above the gantry, and the output shafts of the hydraulic cylinders are fixedly connected to the pressing plate, support plates are fixed at both ends of the punching base, a channel steel is fixed between the two support plates, an air pipe is fixed at the bottom of the channel steel, and one end of the air pipe passes through the support plate and the gantry, a plurality of cylinders with sealed upper ends are fixed on the channel steel, and a plurality of cylinders with sealed upper ends are fixed on the channel steel, and a plurality of cylinders with sealed upper ends are fixed on the channel steel. The cylinders are evenly spaced, a rotating ring is rotatably arranged on the outer side of the cylinder, a pneumatic rotating mechanism is arranged between the rotating ring and the cylinder, two symmetrically distributed fixed rings are fixed on the side ends of the rotating ring, a clamping seat is rotatably arranged on the fixed ring, a clamping mechanism for clamping the punching tool is arranged on the clamping seat, and a self-resetting rotating mechanism is arranged between the clamping seat and the fixed ring, a square tube is fixed on the gantry, and a number of image sensors with equal spacing are installed on the lower end of the square tube, a number of alarm lights are fixed on the upper end of the square tube, and the positions of the alarm lights and the image sensors correspond to each other, and the image sensor is located directly in front of the punching tool at the corresponding position, and a collecting mechanism is arranged under the punching base.

[0008] The working principle of the present invention is: before use, one end of the air pipe is connected to the air press to maintain sufficient air pressure inside the air pipe. When in use, the hydraulic cylinder drives the pressing plate to squeeze downward, so that the punching tool located directly above the die hole moves downward and squeezes on the aluminum veneer to realize the punching function. During the punching process, a number of image sensors monitor the punching shape on the aluminum veneer at all times. When it is detected that there are many punching burrs on the aluminum veneer or the aperture changes, the corresponding alarm light sounds an alarm. At the same time, the pneumatic rotating mechanism at the corresponding position drives the rotating ring to rotate half a circle, and the two clamping seats are swapped. During the rotation process, when the punching tool is blocked by the channel steel, the clamping seat will rotate, so that the punching tool rotates to a horizontal position, and after the rotating ring rotates half a circle, it is reset under the action of the self-resetting rotating mechanism. At this time, the worn punching tool can be replaced, the equipment does not need to be shut down, and the production efficiency will not be affected. After receiving the alarm, the operator can remove the worn punching tool and replace or re-grind it, and then install it on the clamping mechanism. The whole process does not require the equipment to be shut down, thereby improving the punching efficiency and production efficiency.

[0009] The pneumatic rotating mechanism includes a solenoid valve connected to the air pipe, and the other end of the solenoid valve is connected to the bottom of the cylinder. Two symmetrically distributed limit slide grooves are provided at the side end of the cylinder. A pneumatic plate is slidably arranged inside the cylinder, and two support rods are fixed at the side end of the pneumatic plate. The support rods are slidably arranged in the limit slide grooves at corresponding positions. A compression spring is fixed at the upper end of the pneumatic plate, and the upper end of the compression spring is against the sealing end of the cylinder. A pressure relief assembly is provided at the lower end of the pneumatic plate. Two matching slide grooves are provided at the side end of the rotating ring, and the matching slide grooves are aligned with the limit slide grooves at corresponding positions. The support rod is slidably arranged in the matching slide groove, and two semicircular spiral grooves are provided between the two matching slide grooves, and the two semicircular spiral grooves are symmetrically distributed in the center, and a single-pass assembly is provided on the inner side of the matching slide groove.

[0010] With the above structure, when the image sensor signal is triggered, the solenoid valve at the corresponding position is turned on. At this time, the gas is squeezed from the air pipe into the cylinder, and the pneumatic plate is pushed upward through the pressure relief assembly. When the pneumatic plate moves upward, under the action of the single-pass assembly, the support rod slides from the bottom of the matching slide groove to the semicircular spiral groove, forcing the rotating ring to rotate. After the rotating ring rotates half a circle, the support rod rotates to another matching slide groove. At this time, the solenoid valve is closed, and the pneumatic plate and the support rod move downward under the action of the compression spring and the pressure relief assembly, and move to the bottom of the limit slide groove and the matching slide groove, thereby limiting the rotation of the rotating ring.

[0011] The single-pass component includes a guide plate, an embedding groove is opened on the inner wall of the matching slide groove, and a bearing seat is fixed on the upper inner wall of the embedding groove. The guide plate is rotatably arranged on the bearing seat through a torque shaft.

[0012] With the above structure, when the support rod moves downward and passes through the guide plate, the guide plate can be rotated downward and completely rotated into the embedded groove. After the support rod passes, it is reset under the action of the torsion shaft. When the support rod moves upward, the guide plate abuts against the upper side wall of the embedded groove and is in an inclined state, guiding the support rod into the semicircular spiral groove.

[0013] The pressure relief assembly includes a connecting rod fixed to the lower end of the pneumatic plate, a movable piston is fixed to the lower end of the connecting rod, a groove is provided at the side end of the movable piston, a sealing gasket is provided in the groove, and the sealing gasket is against the inner wall of the cylinder, and the diameter of the sealing gasket is smaller than the inner diameter of the groove, the movable piston and the cylinder are matched with each other, a plurality of notches distributed at equal intervals are provided at the upper end of the groove, and a vent is provided at the side end of the cylinder.

[0014] With the above structure, when the solenoid valve is opened, the gas inside the air pipe is squeezed into the cylinder, the aperture of the vent hole is small, the gas loss is less, and the moving piston is pushed upward. At this time, the sealing gasket is against the lower inner wall of the groove and moves up synchronously with the moving piston. When the solenoid valve is closed, the compression spring presses the pneumatic plate downward. In the initial stage, the gas is discharged through the vent hole, and then the moving piston moves downward. At this time, the sealing gasket is against the upper inner wall of the groove. At this time, the gas under the moving piston can be directly discharged through the notch, the exhaust speed is accelerated, and the pneumatic plate can be quickly reset.

[0015] The self-resetting rotating mechanism comprises two first protrusions fixed on both sides of the clamping seat and two second protrusions fixed on both sides of the rotating ring. A tension spring is installed between the first and second protrusions at corresponding positions, and a limiter is provided on the inner side of the clamping seat.

[0016] With the above structure, during the rotation of the rotating ring, the punching tool will rotate when it passes over the channel steel. At this time, the clamping seat and the fixed ring rotate and stretch the tension spring. After the punching tool passes over the channel steel, the tension spring contracts, driving the clamping seat and the punching tool to reset, making it convenient to continue punching.

[0017] The limiter comprises a layer plate fixed inside the clamping seat, an extension rod is fixed on the side end of the layer plate close to the fixing ring, and a notch matching the support rod is formed on the upper end of the extension rod.

[0018] With the above structure, when the support rod moves upward and drives the rotating ring to rotate, the support rod disengages from the notch. At this time, the clamping seat can rotate relative to the fixed ring. When the support rod is reset, the support rod is stuck in the notch. At this time, the clamping seat cannot rotate due to the action of the notch and the support rod, thereby ensuring the stability of the punching tool during punching.

[0019] The clamping mechanism includes a reset spring and a reset ring. A first circular hole is opened above the clamping seat, and a second circular hole is opened at the lower end of the clamping seat, and the diameter of the second circular hole is smaller than the first circular hole. The lower end of the reset spring is fixed on the lower inner wall of the clamping seat, and the reset ring is fixed on the upper end of the reset spring, and the reset ring is abutted against the upper inner wall of the clamping seat. The inner diameter of the reset ring is consistent with the diameter of the second circular hole, and the outer diameter of the reset ring is larger than the diameter of the first circular hole. The punching knife consists of a punching head, a knife rod and a punching block. The diameter of the punching block is consistent with the diameter of the first circular hole, and the knife rod is consistent with the diameter of the second circular hole.

[0020] With the above structure, the punching tool can be disassembled by directly moving it upwards, and vice versa for installation. When in use, the pressing plate presses the punching block downward and compresses the reset spring, and punches holes through the punching head. When the pressing plate rises, the punching tool can be reset under the action of the reset spring.

[0021] The collecting mechanism includes a chute plate fixed at the front end of the control box, and the chute plate is located directly below the punching base. A discharge port connected to the chute plate is opened at the side end of the control box, and a plurality of conical holes are opened below the punching base, and the conical holes are respectively connected to the mold holes at corresponding positions.

[0022] With the above structure, the aluminum sheets and wear debris left by punching fall down into the chute plate through the controlled conical hole, and are finally discharged through the discharge port for easy recycling.

[0023] Compared with the prior art, the punching device for aluminum veneer production has the following advantages:

[0024] 1. The punching tool with severe wear can be automatically replaced by rotating the ring, cylinder, image sensor, alarm light and pneumatic rotating mechanism. The replacement process does not require shutdown, which improves the punching efficiency and production efficiency and reduces the labor burden of operators.

[0025] 2. Through the pressure relief component, the discharge speed of the gas inside the cylinder is accelerated, the replacement speed of the punching tool is increased, and the production efficiency is further improved.

[0026] 3. Through the self-resetting rotating mechanism and the limiter, the replaced punching tool is further limited to prevent it from rotating, ensuring the stability of the punching tool during punching and improving the punching effect.

[0027] 4. The punching tool can be installed and disassembled through the clamping mechanism. The operation steps are simple, which makes it convenient for operators to replace worn tools and improve work efficiency.

[0028] 5. The aluminum sheets and debris left by punching are collected through the collection mechanism for easy recycling. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the hydraulic cylinder 6 drives the pressing plate 5 to press downward, so that the punching tool located just above the die hole moves downward and presses on the aluminum veneer to achieve the punching function. During the punching process, a number of image sensors 19 monitor the punching shape on the aluminum veneer at all times. When it is detected that there are many punching burrs on the aluminum veneer or the aperture changes, the corresponding alarm light 18 sounds an alarm. At the same time, the solenoid valve 12 at the corresponding position 01 is turned on, at this time, the gas is squeezed from the air pipe 9 into the cylinder 10, the vent hole 1216 has a smaller aperture, and the gas loss is less, the moving piston 1212 is pushed upward, and the sealing gasket 1214 abuts against the lower inner wall of the groove 1213, and moves up synchronously with the moving piston 1212, and the guide plate 1210 abuts against the upper side wall of the embedded groove 1208, in an inclined state, guiding the support rod 1204 into the semicircular spiral groove 1207, and the support rod 1204 moves from the bottom of the matching slide groove 1206 to the semicircular spiral groove 1207. 07 slides, forcing the rotating ring 11 to rotate, and the two clamping seats 14 are exchanged. During the rotation process, when the punching tool is blocked by the channel steel 8, the clamping seat 14 will rotate, so that the punching tool rotates to a horizontal position and the tension spring 1503 is stretched. After the rotating ring 11 rotates half a circle, the tension spring 1503 contracts, the clamping seat 14 is reset, and the support rod 1204 is stuck in the notch 1506. At this time, the clamping seat 14 cannot rotate due to the action of the notch 1506 and the support rod 1204, so as to ensure that when punching, the punching The tool is stable, and the worn punching tool can be replaced at this time. The equipment does not need to be shut down, and it will not affect the production efficiency. After receiving the alarm, the operator can remove the worn punching tool and replace it or re-grind it, and then install it on the clamping mechanism 16. The whole process does not require shutdown, which improves the punching efficiency and production efficiency. In addition, the aluminum sheets and wear debris left by punching fall down into the chute plate 2002 through the controlled conical hole 2001, and are finally discharged through the discharge port 2003 for easy recycling.

[0059] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
