Description

Technical Field

[0002] As a common material processing technology, aluminum plate bending has a very wide range of applications and involves many industries and product fields. Aluminum plate bending is a process commonly used to process aluminum alloy plates. By using a numerical control bending machine, the aluminum plate is bent according to requirements to produce the required product parts.

[0003] However, when the bending machine bends the aluminum plate, the aluminum plate is usually positioned by an operator taking it and cooperating with the positioning plate in the bending machine. Only one side is positioned during the bending process. If the aluminum plate deviates to the left and right during bending, the product quality will be reduced; and during the forming process of the aluminum plate, due to the high ductility of the material, aluminum chips are easily generated. The remaining aluminum chips in the lower die will cause indentations on the subsequent aluminum plates; and when it is necessary to replace the die of the bending machine, since the die of the bending machine is heavy and the installation position is high, it is difficult to operate when replacing the upper die and the lower die.

[0037] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12As shown, through holes 205 are provided on both sides of the upper die 204 and the lower die 207.

When the first lead screw 402 rotates, it threadedly drives the slider 401 to move downward. When the slider 401 moves downward, it drives the mold to be replaced to move downward through the connection frame 403 and the adjustment block 404. By the cooperation of the slider 401, the connection frame 403 and the adjustment block 404 to drive the mold to be replaced to move downward, the operation difficulty of replacing the two molds is reduced.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 10 , Figure 11 and Figure 12As shown in the figure, the dust suction structure 5 includes a guide frame 501 fixedly connected to the front of the bending machine body 1 and a guide block 502 slidably connected within the guide frame 501. A connecting rod 504 is fixedly connected to the bottom of the guide block 502, and a dust suction hood 505 is installed at the bottom of the connecting rod 504. A first connecting pipe 506 is installed on the left side of the dust suction hood 505. A fixed frame 508 is fixedly connected to the left side of the bending machine body 1. A collection box 509 is installed in the fixed frame 508. An installation frame 510 is installed within the fixed frame 508, and a filter screen 511 is fixedly connected within the installation frame 510. A vacuum pump 512 is installed above the fixed frame 508. An air suction port of the vacuum pump 512 is installed with a second connecting pipe 513, and the other end of the second connecting pipe 513 is fixedly connected to the fixed frame 508. A hollow pipe 514 is rotatably connected to the front of the fixed frame 508. The other end of the first connecting pipe 506 is fixedly connected to the hollow pipe 514, and the first connecting pipe 506 communicates with the hollow pipe 514. The second connecting pipe 513 communicates to the upper part of the filter screen 511. A third lead screw 503 is rotatably connected within the guide frame 501, and the guide block 502 is threadedly connected to the third lead screw 503. A third motor 507 is installed on the right side of the guide frame 501, and the third lead screw 503 is fixedly connected to the output shaft of the third motor 507. A winding structure 6 is provided between the bending machine body 1 and the hollow pipe 514. The winding structure 6 includes a fixing plate 601 fixedly connected to the left side of the bending machine body 1 and two mounting discs 602 fixedly connected to the lower part of the fixing plate 601. The mounting discs 602 are rotatably connected to the hollow pipe 514. A mounting seat 603 is fixedly connected within the front mounting disc 602. A connecting shaft 604 is rotatably connected within the mounting seat 603, and the connecting shaft 604 is fixedly connected to the hollow pipe 514. A fourth motor 605 is installed in front of the mounting seat 603, and the connecting shaft 604 is fixedly connected to the output shaft of the fourth motor 605. After each aluminum plate is bent and processed, by starting the third motor 507, when the output shaft of the third motor 507 rotates, it drives the third lead screw 503 to rotate. When the third lead screw 503 rotates, it threadedly drives the guide block 502 to slide within the guide frame 501. When the guide block 502 slides, it drives the connecting rod 504 to move to the right. The connecting rod 504 drives the dust suction hood 505 to move to the right. The dust suction hood 505 will drive the first connecting pipe 506 to move. At the same time, the fourth motor 605 can be started. When the output shaft of the fourth motor 605 rotates, it drives the connecting shaft 604 to rotate. The connecting shaft 604 drives the hollow pipe 514 to rotate. At this time, the dust suction hood 505 continuously drives the first connecting pipe 506 to move to the right. The vacuum pump 512 can be started. When the vacuum pump 512 sucks air, the aluminum chips in the lower die 207 enter from the dust suction hood 505 into the first connecting pipe 506, then enter from the first connecting pipe 506 into the hollow pipe 514, and finally are adsorbed at the bottom of the filter screen 511 within the installation frame 510. After the cleaning is completed,Turn off the vacuum pump 512. At this time, the aluminum chips at the bottom of the filter screen 511 will fall into the collection box 509 in the fixed frame 508, and the aluminum chips are collected through the collection box 509. The setting of the filter screen 511 prevents the aluminum chips from entering the vacuum pump 512 through the second connecting pipe 513. At this time, move the guide block 502 to the left. At the same time, the fourth motor 605 drives the connecting shaft 604 and the hollow pipe 514 to rotate, so that the first connecting pipe 506 is wound between the two mounting plates 602. By using the hollow pipe 514 and the two mounting plates 602 in cooperation, it is convenient to wind the first connecting pipe 506, avoiding the influence of the too long first connecting pipe 506 on the bending. At the same time, by cleaning the aluminum chips in the lower die 207, it is avoided that the aluminum chips in the lower die 207 cause indentations on the aluminum plate during the subsequent bending process.,

[0039] Specifically, such as Figure 5 、 Figure 6 、 Figure 9 、 Figure 8 、 Figure 9 and Figure 11As shown in the figure, the positioning structure 7 includes a sliding seat 701 slidably connected to the bending machine body 1 and two adjusting seats 702 slidably connected to the sliding seat 701. An installation shaft 704 is rotatably connected to the adjusting seat 702. A positioning plate 703 is fixedly connected to the installation shaft 704. The positioning plate 703 is rotatably connected to the adjusting seat 702. A torsion spring 705 is fixedly connected between the installation shaft 704 and the adjusting seat 702. A fourth lead screw 706 is rotatably connected to the sliding seat 701. The adjusting seat 702 is threadedly connected to the fourth lead screw 706. The thread directions at both ends of the fourth lead screw 706 are opposite. A fifth lead screw 708 is rotatably connected to the bending machine body 1. The sliding seat 701 is threadedly connected to the fifth lead screw 708. A fifth motor 707 is installed on the right side of the sliding seat 701. The fourth lead screw 706 is fixedly connected to the output shaft of the fifth motor 707. A sixth motor 709 is installed behind the bending machine body 1. The fifth lead screw 708 is fixedly connected to the output shaft of the sixth motor 709. A guide post 710 is fixedly connected to the left side of the bending machine body 1. The sliding seat 701 is slidably connected to the guide post 710. When bending the aluminum plate, first start the sixth motor 709. When the output shaft of the sixth motor 709 rotates, it drives the fifth lead screw 708 to rotate. When the fifth lead screw 708 rotates, it threadedly drives the sliding seat 701 to slide back and forth in the bending machine body 1. When the sliding seat 701 slides, the position of the positioning plate 703 is adjusted. At the same time, the fifth motor 707 can be started. When the output shaft of the fifth motor 707 rotates, it drives the fourth lead screw 706 to rotate. Since the thread directions at both ends of the fourth lead screw 706 are opposite, when the fourth lead screw 706 rotates, it drives the two adjusting seats 702 to slide towards each other. When the adjusting seats 702 slide, they drive the positioning plate 703 to move. By the two adjusting seats 702 sliding towards each other, it is convenient to adjust the position of the positioning plate 703 according to the width of the aluminum plate. At this time, the operator can take the aluminum plate, make one side of the aluminum plate contact with the positioning plate 703, and then start the second hydraulic rod 304. When the telescopic end of the second hydraulic rod 304 extends, it drives the connecting plate 305 to move to the right. When the connecting plate 305 moves to the right, it drives the left sliding rod 301 to move to the right. At the same time, the connecting plate 305 pulls the pull rope 308 to move. The pull rope 308 will be guided through the cooperation of the rotating shaft 306 and the guide roller 307. At the same time, the pull rope 308 pulls the connecting block 309 to move to the left. The connecting block 309 will drive the right sliding rod 301 to move to the left. The right sliding rod 301 will slide with the guide rod 310. The setting of the guide rod 310 makes the sliding of the right sliding rod 301 more stable. The right sliding rod 301 compresses the spring 312. At this time, the two sliding rods 301 move towards each other, driving the two adjusting frames 302 to move towards each other, so that the adjusting frames 302 drive the anti-deviation plates 303 to move, making the anti-deviation plates 303 contact with both sides of the aluminum plate. Through the settings of the anti-deviation plates 303 and the connecting plate 305, the aluminum plate is prevented from shifting during the bending process, thereby improving the bending quality of the aluminum plate. When the positioning is completed,By starting the first hydraulic rod 202, the telescopic end of the first hydraulic rod 202 extends to drive the slide plate 201 to move downward, and the slide plate 201 moves downward to drive the upper mold 204 to move downward. When the upper mold 204 moves downward, it cooperates with the lower mold 207 to bend the aluminum plate.

[0040] When the present invention is in use, when it is necessary to bend the aluminum plate, the sixth motor 709 is first started. When the output shaft of the sixth motor 709 rotates, the fifth screw rod 708 is driven to rotate. When the fifth screw rod 708 rotates, the thread drives the slide 701 to slide back and forth in the bending machine body 1. When the slide 701 slides, the position of the positioning plate 703 can be adjusted. At the same time, the fifth motor 707 can be started. When the output shaft of the fifth motor 707 rotates, the fourth screw rod 706 is driven to rotate. Since the threads at both ends of the fourth screw rod 706 are in opposite directions, the fourth screw rod 706 is When the screw rod 706 rotates, the two adjustment seats 702 are driven to slide toward each other. When the adjustment seats 702 slide, the positioning plate 703 is driven to move. The two adjustment seats 702 slide toward each other, so that the position of the positioning plate 703 can be adjusted according to the width of the aluminum plate. At this time, the operator can take the aluminum plate, put one side of the aluminum plate against the positioning plate 703, and then start the second hydraulic rod 304. When the telescopic end of the second hydraulic rod 304 is extended, it drives the connecting plate 305 to move rightward. When the connecting plate 305 moves to the right, it drives the left sliding bar 301 to move rightward. When the connecting plate 305 pulls the pull rope 308 to move, the pull rope 308 will be guided by the rotating shaft 306 and the guide roller 307. At the same time, the pull rope 308 pulls the connecting block 309 to move leftward, and the connecting block 309 will drive the right sliding bar 301 to move leftward. The right sliding bar 301 will slide with the guide rod 310. The setting of the guide rod 310 makes the right sliding bar 301 slide more smoothly. The right sliding bar 301 shrinks the spring 312. At this time, the two sliding bars 301 move toward each other, driving the two adjustment frames 302 to move toward each other. The adjusting frame 302 drives the anti-deflection plate 303 to move, so that the anti-deflection plate 303 contacts the two sides of the aluminum plate. The anti-deflection plate 303 and the connecting plate 305 are arranged to avoid the aluminum plate from deflecting during the bending process, thereby improving the bending quality of the aluminum plate. After the positioning is completed, the first hydraulic rod 202 is started, and the telescopic end of the first hydraulic rod 202 is extended to drive the slide plate 201 to move downward, and the slide plate 201 moves downward to drive the upper mold 204 to move downward, and the upper mold 204 cooperates with the lower mold 207 to bend the aluminum plate.

[0041] After each aluminum plate is bent, by starting the third motor 507, when the output shaft of the third motor 507 rotates, it drives the third lead screw 503 to rotate. When the third lead screw 503 rotates, it thread-drives the guide block 502 to slide within the guide frame 501. When the guide block 502 slides, it drives the connecting rod 504 to move to the right. The connecting rod 504 drives the dust suction hood 505 to move to the right. The dust suction hood 505 drives the first connecting pipe 506 to move. At the same time, the fourth motor 605 can be started. When the output shaft of the fourth motor 605 rotates, it drives the connecting shaft 604 to rotate. The connecting shaft 604 drives the hollow pipe 514 to rotate. At this time, the dust suction hood 505 continuously drives the first connecting pipe 506 to move to the right. The vacuum pump 512 can be started. When the vacuum pump 512 sucks air, the aluminum chips in the lower die 207 enter the first connecting pipe 506 from the dust suction hood 505, then enter the hollow pipe 514 from the first connecting pipe 506, and finally are adsorbed at the bottom of the filter screen 511 in the mounting frame 510. After the cleaning is completed, the vacuum pump 512 is turned off. At this time, the aluminum chips at the bottom of the filter screen 511 will fall into the collection box 509 in the fixed frame 508, and the aluminum chips are collected by the collection box 509. The setting of the filter screen 511 prevents the aluminum chips from entering the vacuum pump 512 from the second connecting pipe 513. At this time, the guide block 502 is moved to the left, and at the same time, the fourth motor 605 drives the connecting shaft 604 and the hollow pipe 514 to rotate, so that the first connecting pipe 506 is wound between the two mounting disks 602. By using the hollow pipe 514 and the two mounting disks 602 in cooperation, it is convenient to wind the first connecting pipe 506, avoiding the influence of the too long first connecting pipe 506 on the bending. At the same time, by cleaning the aluminum chips in the lower die 207, it is avoided that the aluminum chips in the lower die 207 cause indentations on the aluminum plate during the subsequent bending process;

[0042] When it is necessary to replace two molds at the same time, the first motor 406 can be started. When the output shaft of the first motor 406 rotates, it drives the second lead screw 405 to rotate. When the second lead screw 405 rotates, it thread-drives the adjusting block 404 to move backward. When the adjusting block 404 drives the insertion rod 407 to move until it aligns with the through holes 205 on both sides of the mold, the second hydraulic rod 304 is started, so that the two sliding rods 301 and the adjusting frame 302 drive the two insertion rods 407 to move towards each other, and the insertion rods 407 are inserted into the through holes 205. At this time, the fixing bolts of the corresponding mold can be removed. After the adjusting block 404 moves forward a certain distance, the second motor 409 is started. When the output shaft of the second motor 409 rotates, it drives the first lead screw 402 to rotate. When the left first lead screw 402 rotates, it drives the right first lead screw 402 to rotate through the belt and the pulley 408, so that the two first lead screws 402 rotate simultaneously. When the first lead screw 402 rotates, it thread-drives the slider 401 to move downward. When the slider 401 moves downward, it drives the mold to be replaced to move downward through the connecting frame 403 and the adjusting block 404. By the cooperation of the slider 401, the connecting frame 403 and the adjusting block 404 to drive the mold to be replaced to move downward, the operation difficulty of replacing the two molds is reduced.
