Description

Technical Field

[0001] The invention relates to the technical field of aluminum veneer cutting, and in particular to an aluminum veneer cutting device for curtain wall production. Background Art

[0002] Curtain wall is the outer wall of the building, which is non-load-bearing and is hung like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is composed of panels and supporting structure systems, and can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and is an external protective structure or decorative structure of the building that does not bear the effects of the main structure (the external wall frame support system is also a type of curtain wall system).

[0003] The main material of the curtain wall is aluminum, which is formed by bending aluminum veneers. Before bending, the aluminum veneers need to be bent into the shape of the curtain wall through a laser cutter. Because it is used for curtain walls, the thickness of the aluminum veneer is relatively thin. Because the material of aluminum is softer than other metal materials, and because the sizes of aluminum veneers are different, when the aluminum veneer is placed on the cutting bed, if the two ends of the aluminum veneer are located between the teeth of the sawtooth cutting bed, then the two ends of the aluminum veneer cannot be supported by the sawtooth cutting bed, which will cause the unsupported edges of the aluminum veneer to sink;

[0004] The sinking edge of the aluminum veneer will cause the edge of the horizontal plate to tilt. If you still cut according to the cutting distance of the horizontal plate when you encounter a drooping and tilted plate surface, there will be a cutting error. In addition, cutting when it is tilted will cause the cut surface to tilt. Because it is a material used for curtain walls, metal slag will appear during the cutting process, and the metal slag will scratch the surface of the plate, affecting the appearance of the curtain wall.

[0043] The driving mechanism 4 is installed on one side of the lifting and cleaning mechanism 3 and is used to drive the lifting and cleaning mechanism 3 to operate.

[0044] The driving mechanism 4 includes a motor fixing frame 41 fixed to one side of one of the fixing frames 31, a motor 42 is fixed inside the motor fixing frame 41, a gear 43 is fixed to one end of the output shaft of the motor 42, one side of the gear 43 is meshed with the one-way gear 1 33, and the other side is meshed with the one-way gear 2 321;

[0045] A controller is fixed on one side of the bed frame 11 , and the controller is electrically connected to the rodless cylinder 1 22 , the rodless cylinder 2 23 , the laser cutter 24 , the motor 42 , the pressure sensor 39 and the distance sensor 311 .

[0046] Working principle:

[0047] First, the cutting program is started through the controller, and then the motor 42 is started according to the program to drive the gear 43 to rotate forward. The forward rotation of the gear 43 satisfies the one-way gear 1 33 to drive the double-stage reciprocating threaded rod 32 to rotate. The double-stage reciprocating threaded rod 32 rotates to make the two moving plates 34 approach each other. The movement of the moving plate 34 drives the multiple sleeve plates 36 to move. The sleeve plate 36 pushes the paddle plate 310 to move forward through the spring 38. The paddle plate 310 moves forward to drive the detection mechanism and the support plate 322 to move. The support plate 322 drives the slag removal triangular blade 312 to move.

[0048] The movement of the moving plate 34 drives the L-shaped supporting plate 313, the rotating shaft 1 314, the lever 315, the bevel gear 1 316 and the mounting plate 317 to move. The mounting plate 317 moves outside the rotating shaft 2 318 and pushes the bevel gear 2 319 to move, so that the bevel gear 2 319 is always meshed with the bevel gear 1 316. Then the bevel gear 2 319 drives the slider to slide in the slide groove 320. The ramp block 323 moves with the support plate 322, and then is inserted from one side of the aluminum single plate 13 to the bottom. The ramp block 323 makes the drooping edge of the aluminum single plate 13 slide along the slope to the top of the support plate 322, so that the drooping edge of the aluminum single plate 13 becomes horizontal, and the edge of the aluminum single plate 13 is lowered. The sinking will make the horizontal plate tilted. If the horizontal plate is cut according to the cutting moving distance and the plate surface is still cut after encountering a sagging and tilted plate surface, there will be a cutting error, and the cut surface at one end of the cutting plate will be tilted when tilted. Therefore, the sinking position of the edge of the aluminum single plate 13 can be lifted up to avoid affecting the cutting accuracy of this position. Continuing to approach will center the aluminum single plate 13 in the middle and correct the tilted aluminum single plate 13. When the pressure sensor 39 feels the pressure, it means that the dial plate 310 is in contact with the aluminum single plate 13. When the pressure sensors 39 within the size range of the aluminum single plate 13 all feel the pressure, it means that the aluminum single plate 13 has been corrected and centered.

[0049] The controller controls the mobile cutting mechanism 2 to cut along the edge of the aluminum single plate 13, and cuts it into a shape that can be bent into a curtain wall. When the edge of the aluminum single plate 13 adjusted to a horizontal position is cut, the distance sensor 311 located at the edge of the aluminum single plate 13 detects the movement of the laser cutter 24, and the motor 42 is started to drive the gear 43 to reverse. The reversal of the gear 43 satisfies the direction of the one-way gear 2 321 to drive the second shaft 318 to rotate. The rotation of the second shaft 318 drives the bevel gear 2 319 to rotate by the slide groove 320 and the slider. The bevel gear 2 319 drives the bevel gear 1 316 to rotate so that the shaft 1 314 drives multiple levers 315 to rotate. When the lever 315 rotates, it will contact the side of the dial plate 310 that contacts the aluminum single plate 13. Continuing to rotate will push the dial plate 310 and the damping rod 37 backward to compress the spring 38. The dial plate 310 pushes back to drive the support plate 322 and the ramp block 323 The slag removing triangular blade 312 moves and is pulled out from under the aluminum single plate 13. The other unmoved supporting plates 322 still lift the edge of the aluminum single plate 13, so that there is no object under the cutting position while keeping the aluminum single plate 13 in a horizontal state. As the laser cutter 24 moves and cuts, the paddles 310 at different positions drive the supporting plates 322 to withdraw, making room for the cutting position for the distance laser cutter 24 that is about to move over. After the cutting at this position, the spring 38 pushes the damping rod 37 and other structures to reset, and continues to lift the aluminum single plate 13. After the processing is completed, the soft aluminum single plate 13 is manually removed from the serrated support plate 12, and then the motor 42 is started again to drive the gear 43 to rotate forward, so that the double-section reciprocating threaded rod 32 continues to rotate, so that the two moving plates 34 continue to move, the slag removing triangular blade 312 continues to move, and then the cutting slag remaining in the tooth groove is removed, and the moving plate 34 moves to the wire tail and then moves back and forth to complete the processing.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
