Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a pneumatic device with multi-position adjustment. Background Technology

[0002] Right-angle trimming of board edges refers to machining or stamping to turn right angles on the edges of boards into rounded corners with a certain radius. This is mainly used to improve appearance, eliminate stress concentration, enhance safety (avoiding scratches), or meet specific process requirements. Current right-angle trimming of board edges is primarily achieved through a multi-position adjustable starting device. This device is used in the tracking mechanism of edge banding machines. The motor follows the movement of the board, milling the two ends of the edge banding strip into rounded corners. The board is conveyed to the tracking position via a pressure beam guide rail and fixed to the tracking blade by a template and a contour wheel. Conventional tracking requires manual adjustment of the blade's forward and backward movement using an adjusting screw, depending on the thickness of the edge banding strip, to increase or decrease the cutting area. When the edge banding strip is thick, the tracking blade moves forward; when the edge banding strip is thin, the tracking blade moves backward. This method cannot be quickly implemented when trimming different edge banding strips, resulting in low work efficiency. Utility Model Content

[0024] This utility model relates to a pneumatic device with multi-position adjustment, such as... Figure 1-7As shown, the system includes a base plate 1 and a mounting frame 2. The mounting frame 2 is located on the upper end of the base plate 1 and is equipped with an upper tracking trimming mechanism 3. A lower tracking trimming mechanism 4 is located on the upper end of the base plate 1 away from the mounting frame 2. A pressure beam guide rail 5 for transporting the sheet metal is located at the front end of the upper tracking trimming mechanism 3 and the lower tracking trimming mechanism 4 on the upper end of the base plate 1.

The lower tracking trimming mechanism 4 includes a lower tracking moving mechanism 41, a lower tracking trimming component 42, and a lower tracking trimming advance / retreat component 43. The upper tracking trimming component 32 and the upper tracking trimming advance / retreat component 33 are connected to the upper tracking moving mechanism 41. The lower tracking trimming assembly 42 and the lower tracking trimming forward / backward assembly 43 are installed with the lower tracking moving mechanism 41. The upper tracking trimming forward / backward assembly 33 is connected to the upper tracking trimming assembly 32, and the lower tracking trimming forward / backward assembly 43 is connected to the lower tracking trimming assembly 42 in a front-to-back position transmission connection, so as to drive the upper tracking trimming assembly 32 and the lower tracking trimming assembly 42 to move in a front-to-back position. The upper tracking trimming assembly 32 is slidably connected to the upper edge of the plate, and the lower tracking trimming assembly 42 is slidably connected to the lower edge of the plate. By setting the base plate 1 and the mounting frame 2, it serves as the main body for the installation of the multi-position adjustable pneumatic device. The upper tracking trimming mechanism 3 and the lower tracking trimming mechanism 4 are respectively used to track and trim the upper edge. The R-angle and the lower edge R-angle of the tracking trimming are controlled by a pressure beam guide rail 5. The pressure beam presses the board from the top and bottom to ensure it is in a horizontal position. The board is transported along the pressure beam by a crawler, allowing it to pass sequentially through the lower tracking trimming mechanism 4 and the upper tracking trimming mechanism 3. An upper tracking moving mechanism 31, an upper tracking trimming assembly 32, and an upper tracking trimming advance / retreat assembly 33 are included. The upper tracking moving mechanism 31 moves the upper tracking trimming assembly 32 and the upper tracking trimming advance / retreat assembly 33, causing the upper tracking trimming assembly 32 to follow the board and mill the two ends of the edge banding strip along the upper edge of the board into rounded arcs. The lower tracking moving mechanism 41 and the lower tracking trimming assembly 33 then complete the process. The lower tracking trimming advance and retreat component 43 and the lower tracking moving mechanism 41 drive the lower tracking trimming component 42 and the lower tracking trimming advance and retreat component 43 to move, so that the lower tracking trimming component 42 follows the wooden board and mills the two ends of the edge banding strip sealed on the lower edge of the wooden board into arcs at right angles. The upper tracking trimming advance and retreat component 33 and the upper tracking trimming component 32, and the lower tracking trimming advance and retreat component 43 and the lower tracking trimming component 42 are connected in a front-to-back position so that the upper tracking trimming component 32 and the lower tracking trimming component 42 can move back and forth, thereby adapting to edge banding strips of different thicknesses. The R angle of the tracking trimming is quickly adjusted by the advance and retreat of the cylinder, thereby solving the problem to be solved by this utility model.

[0025] In an embodiment of this utility model, the lower tracking and moving mechanism 41 includes a first height adjusting cylinder 411, a first rotation adjusting cylinder 412, a lower fixed bracket 413, and a lower swing arm 414. The first height adjusting cylinder 411 and the first rotation adjusting cylinder 412 are rotatably mounted on the lower and upper ends of the base plate 1, respectively. The bottom of the lower swing arm 414 is rotatably mounted on the upper end of the base plate 1. The top of the lower swing arm 414 is rotatably connected to the bottom of the lower fixed bracket 413. The telescopic ends of the first height adjusting cylinder 411 are rotatably connected to a position near the middle of the lower swing arm 414 via telescopic rods. The telescopic end of 1 is rotatably connected to the bottom of the lower fixed bracket 413 away from the lower swing arm 414 via a telescopic rod. By setting a first height adjustment cylinder 411, a first rotation adjustment cylinder 412, a lower fixed bracket 413, and a lower swing arm 414, the telescopic end of the first height adjustment cylinder 411 drives the lower swing arm 414 to rotate via the telescopic rod, the lower swing arm 414 drives the lower fixed bracket 413 to rotate, the telescopic end of the first rotation adjustment cylinder 412 drives the lower fixed bracket 413 to rotate via the telescopic rod, and the lower fixed bracket 413 drives the tracking knife 322 to rotate to complete the R-angle tracking trimming of the lower edge of the plate.

[0026] In an embodiment of this utility model, the upper tracking and moving mechanism 31 includes a second height adjusting cylinder 311, a second rotation adjusting cylinder 312, an upper fixed bracket 313, and an upper swing arm 314. The second height adjusting cylinder 311 and the second rotation adjusting cylinder 312 are rotatably mounted on the side and top of the mounting frame 2, respectively. The top of the upper swing arm 314 is rotatably mounted on the top of the mounting frame 2, and the bottom of the upper swing arm 314 is rotatably connected to one end of the upper fixed bracket 313. The telescopic end of the second height adjusting cylinder 311 is rotatably connected to the end of the upper fixed bracket 313 away from the upper swing arm 314 via a telescopic rod. The telescopic end of the adjusting cylinder 312 is rotatably connected to a position near the middle of the upper swing arm 314 via a telescopic rod. By setting a second height adjusting cylinder 311, a second rotation adjusting cylinder 312, an upper fixed bracket 313, and an upper swing arm 314, the telescopic end of the second height adjusting cylinder 311 drives the upper swing arm 314 to rotate via the telescopic rod. The upper swing arm 314 drives the upper fixed bracket 313 to rotate. The telescopic end of the second rotation adjusting cylinder 312 drives the upper fixed bracket 313 to rotate via the telescopic rod. The upper fixed bracket 313 drives the tracking knife 322 to rotate to complete the R-angle tracking trimming of the upper edge of the plate.

[0027] In an embodiment of this utility model, the upper tracking trimming advance / retreat assembly 33 includes two guide posts 331, a mounting plate 332, an advance / retreat cylinder 333, a transmission block 334, and an advance / retreat plate 335. The two guide posts 331 are respectively mounted on both sides of the upper fixed bracket 313. The bottom sides of the mounting plate 332 are respectively mounted to the two ends of the two guide posts 331. The advance / retreat plate 335 is slidably connected to the mounting plate 332 via a slider. The advance / retreat cylinder 333 is mounted on one end of the advance / retreat plate 335. A transmission block 334 is mounted on the mounting plate 332 at the position corresponding to the advance / retreat cylinder 333. The telescopic end of the advance / retreat cylinder 333 is sleeved with the transmission block 334 via a telescopic rod. The tracking trimming assembly 32 includes a tracking motor 321, a tracking blade 322, a contouring wheel 323, and a template 324. The template 324 and the contouring wheel 323 are mounted on the mounting plate 332 near the end of the tracking blade 322, with the contouring wheel 323 positioned at the front end of the template 324. The template 324 has a hollow structure in its center. The tracking blade 322 is rotatably connected to the center of the template 324. The tracking motor 321 is mounted on the side of the advance / retract plate 335 away from the mounting plate 332. The output end of the tracking motor 321 is mounted to the tracking blade 322. The lower tracking trimming advance / retract assembly 43 has the same structure as the upper tracking trimming advance / retract assembly 33. 2. Similar in structure to the upper tracking trimming component 32, it incorporates two guide posts 331, a mounting plate 332, a forward / reverse cylinder 333, a transmission block 334, and a forward / reverse plate 335. The two guide posts 331 are respectively installed on both sides of the fixed bracket. The mounting plate 332 is fixed to the upper end of the upper fixed bracket 313 via the guide posts 331. The telescopic end of the forward / reverse cylinder 333 is connected to the transmission block 334 via a telescopic rod. When the forward / reverse cylinder 333 extends, it moves one end of the telescopic rod towards the extended mounting plate 332, pushing the forward / reverse plate 335 away from the mounting plate 332. When the forward / reverse cylinder 333 retracts, it moves one end of the telescopic rod towards the transmission block 334, pushing the forward / reverse plate 335 away from the mounting plate 332. The moving plate 335 moves towards the mounting plate 332, causing the moving plate 335 to move back and forth via the slider, thereby driving the tracking knife 322 to move back and forth. By setting up a tracking motor 321, tracking knife 322, contour wheel 323, and template 324, the output end of the tracking motor 321 drives the tracking knife 322 to rotate. The template 324 abuts against the side of the edge banding, and the contour wheel 323 abuts against the bottom of the board, so that the board is fixed at the tracking knife 322. The upper tracking moving mechanism 31 and the lower tracking moving mechanism 41 drive the motor to follow the board, and the two ends of the edge banding sealed by the board are milled into arcs at right angles.

[0028] In this embodiment of the invention, the forward / reverse plate 335 is threadedly connected to a front limiting screw 6 and a rear limiting screw 7 on both sides symmetrically related to the forward / reverse cylinder 333. One end of each of the front and rear limiting screws 6 passes through the forward / reverse plate 335. A front limiting block 8 is provided on the mounting plate 332 at the position corresponding to the front limiting screw 6. An anti-detachment block 9 is installed at the end of the front limiting screw 6 that passes through the forward / reverse plate 335. The anti-detachment block 9 is internally sleeved with the front limiting block 8. By setting the front limiting screw 6 and the rear limiting screw 7, the front limiting screw 6 can be rotated. The front limit screw 6 drives one end of the anti-detachment block 9 to move inside the front limit block 8. The anti-detachment block 9 has a moving space in the length direction of the front limit screw 6. By adjusting the height of the anti-detachment block 9 inside the front limit block 8, the forward distance of the advance plate 335 is limited, so that the component of the tracking knife 322 completes the front positioning. By rotating the rear limit screw 7 and adjusting the distance between the end of the rear limit screw 7 close to the mounting plate 332 and the mounting plate 332, the backward distance of the advance plate 335 is limited, so that the component of the tracking knife 322 completes the positioning.

[0029] In this embodiment of the utility model, position displays are installed on both sides of the advance / retreat plate 335, which are rotatably connected to the front limit screw 6 and the rear limit screw 7. By setting the position displays, it is convenient to accurately control the adjustment distance of the front limit screw 6 and the rear limit screw 7.

[0030] In an embodiment of this utility model, a waste discharge pipe 10 covering the outside of the tracking knife 322 is installed on the side of the mounting plate 332 away from the template 324. An exhaust fan is installed at the end of the waste discharge pipe 10 away from the tracking knife 322. The end of the exhaust fan away from the tracking knife 322 is connected to a collection container. By setting the exhaust fan, the exhaust fan generates suction at the end of the waste discharge pipe 10 away from the tracking knife 322, so that the waste generated by trimming is sucked into the waste discharge pipe 10 and then discharged into the collection container by the exhaust fan, which facilitates waste collection and avoids waste splashing to other work stations.

[0031] In an embodiment of this utility model, a buffer rod 11 is provided on the mounting frame 2. The telescopic end of the buffer rod 11 abuts against the side of the second rotation adjustment cylinder 312. By providing the buffer rod 11 and the telescopic end of the buffer rod 11 abutting against the side of the second rotation adjustment cylinder 312, the vibration generated by the second rotation adjustment cylinder 312 is buffered, ensuring the stability of the movement process.

[0032] In an embodiment of this utility model, a buffer block 12 is provided on the mounting frame 2 at the position corresponding to the second rotation adjustment cylinder 312. The buffer block 12 is made of rubber. The buffer block 12 limits the rotation range of the second rotation adjustment cylinder 312 and buffers the vibration of the second rotation adjustment cylinder 312, thereby further improving the buffering effect of the second rotation adjustment cylinder 312.

[0033] In this embodiment of the invention, the interior of the mounting frame 2 has a hollow structure. By setting the interior of the mounting frame 2 to have a hollow structure, it is easier for the upper tracking trimming mechanism 3 to move inside the mounting frame 2, thereby reducing the weight of the device.

[0034] In use, firstly, the pressure beam guide rail 5 transports the sheet metal to the tracking point, allowing the sheet metal to pass sequentially through the lower tracking trimming mechanism 4 and the upper tracking trimming mechanism 3. The telescopic end of the first height adjustment cylinder 411 drives the lower swing arm 414 to rotate via the telescopic rod, which in turn drives the lower fixed bracket 413 to rotate. The telescopic end of the first rotation adjustment cylinder 412 drives the lower fixed bracket 413 to rotate via the telescopic rod, which in turn drives the tracking blade 322 to rotate and complete the R-angle tracking trimming of the lower edge of the sheet metal. The telescopic end of the second height adjustment cylinder 311 drives the upper swing arm 314 to rotate via the telescopic rod, which in turn drives the upper fixed bracket 313 to rotate. The telescopic end of the throttle cylinder 312 drives the upper fixed bracket 313 to rotate via the telescopic rod. The upper fixed bracket 313 drives the tracking knife 322 to rotate to complete the R-angle tracking trimming of the upper edge of the plate. The front limit screw 6 holds the tracking knife 322 in place, and the tracking knife 322 can be positioned forward by adjusting the front limit screw 6. If the cylinder moves backward, the slider drives the tracking knife 322 to move backward, and the rear limit screw 7 holds the tracking knife 322 in place. The tracking knife 322 can be positioned backward by adjusting the rear limit screw 7. The movement distance of the tracking knife 322 is limited, and the trimming of two different thicknesses of edge banding tape can be achieved with one click.
