Generally, patterns for assembly or aesthetics, as well as through holes for positioning, are cut on the surface of the facade aluminum panels in advance for assembly. During the punching process, a clamping device is used for positioning to facilitate punching.

Each group of stepped clamps can be released from control individually. After the solenoid valve is closed, the support piston A will not lift the hole-retaining rod, thereby creating a space for accommodating punching or drilling, which is convenient for processing.

The waste chips are collected in the stepped clamp, and the waste chips can be conveniently collected when the hole-retaining rod and the stepped clamp are aligned.

[0018] 2. A mobile load-bearing frame is provided to provide a highly applicable positioning function. The two sides of the plate can be positioned through the flange of the load-bearing wheel. The load-bearing wheel provides a rotating effect so that the plate can still be moved. The built-in lead screw is used to drive the L-shaped push frame to move, and the other two sides of the plate can be fixed. In addition, the specific position of the plate can be adjusted and controlled by controlling the position of each group of L-shaped push frames and the load-bearing wheels on both sides, which provides convenience for the execution of different projects.

[0019] 3. An L-shaped limiting beam is set up to flexibly control the clamping position. The pressing beam lead screw is used to drive the L-shaped limiting beam to move and adjust the position of the L-shaped limiting beam to avoid the L-shaped limiting beam affecting the blanking. After the L-shaped limiting beam moves to a position where it does not affect the blanking, the clamping can be carried out. When the plate contacts the pressing block, the clamping is completed and the blanking can be carried out. The structure of the upper and lower positioning plate can be adjusted, and it has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, scheme and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention.

[0031] Example 1: Please refer to the attached drawings in the specification. Figures 1 to 8 As shown:

[0033] Among them, the telescopic end of the support piston B203 is fixedly provided with a stepped clamp 205, and the stepped clamp 205 is a square structure that is wide at the top and narrow at the bottom. The lower end of the stepped clamp 205 slides in the mounting stand 1, and the upper sides of the stepped clamp 205 fit together.

[0034] Among them, the telescopic ends of the supporting piston A202 are fixedly provided with a hole rod 206, and the hole rod 206 is a stepped cylindrical structure that is wide at the top and narrow at the bottom. The hole rod 206 slides inside the stepped clamp 205, and the hole rod 206 can slide downward inside the stepped clamp 205.

[0035] The bottom of the supporting piston A202 is fixedly connected with a solenoid valve 204 , and the lower end of the solenoid valve 204 and the lower end of the supporting piston B203 are connected by an integrated pipeline, and the integrated pipeline is also connected to a hydraulic pump 207 .

[0036] Among them, the outer side of the top of the movable carrier frame 3 is integrally provided with a vertical plate structure, and the inner side of the vertical plate structure is evenly distributed with load-bearing wheels 301, and the main body of the load-bearing wheel 301 is a T-shaped structure; the top surfaces of the stepped clamp 205 and the hole-retaining rod 206 can be raised to be higher than the load-bearing wheel 301; the adjacent surfaces of the movable carrier frames 3 on both sides are provided with sliding grooves 302.

[0037] Among them, a built-in lead screw 303 is rotatably arranged on the inner side of the sliding groove 302, and a positioning motor 304 is fixedly arranged at both ends of the movable carrier frame 3. The movable carrier frame 3 is connected to the built-in lead screw 303 through a transmission to provide a driving force; an L-shaped push frame 305 is slidably arranged in the sliding groove 302 through a guide rail, and the L-shaped push frame 305 is threadedly connected to the built-in lead screw 303.

[0038] The hydraulic pump 207 is a bidirectional pump, and the outer end of the hydraulic pump 207 is connected to an oil tank for carrying hydraulic oil.

[0039] Among them, the bottom surface of the top turning point of the L-shaped limiting beam 6 is fixedly provided with a pressing block 601, and the turning points of the L-shaped limiting beams 6 on both sides are close to the middle of the mounting stand 1.

[0040] like Figure 1-8 As shown, the punching machine is mounted above the device so as to process the sheet; when punching, the sheet is placed above the load-bearing wheels 301 on both sides, and then the side electric cylinder 102 is started to bring the movable load-bearing frames 3 on both sides closer, and the two sides of the sheet are positioned by the flange parts of the load-bearing wheels 301. At this time, the load-bearing wheels 301 provide a rotation effect so that the sheet can still move. Through program control and data setting, the positioning motor 304 is started to drive the built-in lead screw 303 to rotate, and the built-in lead screw 303 is used to drive the L-shaped push frame 305 to move, so that the other two sides of the sheet can be fixed, and the specific position of the sheet can be adjusted and controlled by controlling the positions of each group of L-shaped push frames 305 and the load-bearing wheels 301 on both sides;

[0041] Start the side end motor 5 to drive the pressure beam lead screw 4 to rotate, use the pressure beam lead screw 4 to drive the L-shaped limit beam 6 to move, adjust the position of the L-shaped limit beam 6 to prevent the L-shaped limit beam 6 from affecting the blanking, and after the L-shaped limit beam 6 moves to a position where it does not affect the blanking, it can be pressed;

[0042] The hydraulic pump 207 is used to deliver hydraulic oil to each group of supporting pistons A202 and supporting pistons B203, and the stepped clamp 205 and the hole-retaining rod 206 are extended synchronously to lift the plate. When the top of the plate contacts the pressing block 601, the clamping is completed and punching can be performed at this time.

[0043] Example 2: On the basis of Example 1, when punching is required, it is necessary to ensure that the punching machine or drilling drill bit passes through the plate. First, reverse the hydraulic pump 207 to retract the support piston A202 and the support piston B203. At this time, through program positioning, move the plate to move the punching position to a position aligned with an adjacent group of hole-leaving rods 206, and close the solenoid valve 204 connected to the bottom of the support piston A202 under the group of hole-leaving rods 206. Start the hydraulic pump 207 again to open each group of support pistons A202 and support pistons B203. Since the solenoid valve 204 is closed, the group of support pistons A202 will not lift the hole-leaving rod 206, leaving a hole in the stepped clamp 205, ensuring that the punching or drilling structure can pass through the plate and enter the middle of the stepped clamp 205.

[0044] Embodiment 3: Based on Embodiment 1, each group of supporting pistons A202 and supporting pistons B203 are uniformly controlled by a hydraulic pump 207, each group of supporting pistons A202 and supporting pistons B203 can be replaced and maintained separately, and each supporting piston A202 is controlled separately by a solenoid valve 204;

[0045] The solenoid valve 204 is used to independently control the supporting piston A202, which is more cost-effective than using an electric cylinder or other driving elements. The cost of the solenoid valve 204 and the supporting piston A202 is much lower than that of a separate driving component. Bulk purchasing can greatly reduce costs, and is easy to maintain and replace individually.

[0046] The specific usage and function of this embodiment: In the present invention, the main device before work Figure 1state, at this time, the plate is placed above the load-bearing wheels 301 on both sides, and then the side electric cylinder 102 is started to bring the movable load-bearing frames 3 on both sides together, and the two sides of the plate are positioned by the flange parts of the load-bearing wheels 301. At this time, the load-bearing wheels 301 provide a rotation effect, so that the plate can still move. Through program control and data setting, the positioning motor 304 is started to drive the built-in lead screw 303 to rotate, and the built-in lead screw 303 is used to drive the L-shaped push frame 305 to move, so that the other two sides of the plate can be fixed, and the specific position of the plate can be adjusted and controlled by controlling the positions of each group of L-shaped push frames 305 and the load-bearing wheels 301 on both sides;

[0047] A punching machine is mounted above the device to process the sheet material;

[0048] Start the side end motor 5 to drive the pressure beam lead screw 4 to rotate, use the pressure beam lead screw 4 to drive the L-shaped limit beam 6 to move, adjust the position of the L-shaped limit beam 6 to prevent the L-shaped limit beam 6 from affecting the blanking, and after the L-shaped limit beam 6 moves to a position where it does not affect the blanking, it can be pressed;

[0049] The hydraulic pump 207 is used to deliver hydraulic oil to each group of supporting pistons A202 and B203, and the stepped clamp 205 and the hole-retaining rod 206 are extended synchronously to lift the plate. When the upper part of the plate contacts the pressing block 601, the clamping is completed, and blanking can be performed at this time;

[0050] If punching is required, it is necessary to ensure that the punching machine or the drill bit of the drilling machine passes through the plate. First, reverse the hydraulic pump 207 to shrink the support piston A202 and the support piston B203. At this time, through program positioning, move the plate to move the punching position to a position aligned with an adjacent group of hole-retaining rods 206, and close the solenoid valve 204 connected to the bottom of the support piston A202 under the group of hole-retaining rods 206. Start the hydraulic pump 207 again to prop open each group of support pistons A202 and support pistons B203. Since the solenoid valve 204 is closed, the group of support pistons A202 will not lift the hole-retaining rods 206, leaving a hole in the stepped clamp 205, ensuring that the punching or drilling structure can pass through the plate and enter the middle of the stepped clamp 205.

[0051] Each group of supporting pistons A202 and supporting pistons B203 is uniformly controlled by a hydraulic pump 207, and each group of supporting pistons A202 and supporting pistons B203 can be replaced and maintained separately.
