[0011] Compared with the prior art, the present invention has the following beneficial effects: A cable tray roll forming device is provided, which arranges a motor on the top of a support frame to facilitate the movement of movable rods connected at both ends driven by the motor. When the movable rod swings downward under the drive of the motor, it will drive one end of an elliptical plate movably connected to the bottom to move downward synchronously. At this time, the first movable block connected to the other end of the elliptical plate will slide downward along the first sliding rod, and drive the cutting block fixedly connected to the bottom of the first movable block to move toward the cable tray blank until it is cut to a preset length.

[0014] A cable tray roll forming device is provided by arranging a concave block at the output shaft end of a double-axis cylinder. When the double-axis cylinder is driven, it can drive the movement of the concave block and the hollow block movably connected to its groove. When the double-axis cylinder contracts, the concave block will pull the push block to move toward the center. At this time, the second rotating shaft inside the push block rotates under the support of the hollow block, thereby driving the top grinding block to deviate to both sides, so that the cable tray model can be placed on the positioning protrusion on the top of the double-axis cylinder.

Example 2: Based on Example 1, Figure 3-8As shown, the movable device 51 includes a support frame 511, a motor 512 is provided on the top of the support frame 511, and the top of the support frame 511 is fixedly connected to the bottom of the motor 512, first rotating shafts 513 are provided on both sides of the motor 512, and both sides of the motor 512 are fixedly connected to the bottom of the first rotating shaft 513, movable rods 514 are provided on the tops of the two first rotating shafts 513, and the tops of the two first rotating shafts 513 are movably connected to one end of the movable rod 514, and an elliptical plate 515 is provided on the outer side of the other end of the movable rod 514, and the outer side of the other end of the movable rod 514 is movably connected to the top of the elliptical plate 515.

[0019] The inner raised portions at the bottom of the two elliptical plates 515 are both provided with a first moving block 516, and the inner raised portions at the bottom of the two elliptical plates 515 are movably connected to the raised portions at both ends of the first moving block 516, a first sliding rod 517 is provided at the rear end of the first moving block 516, and the rear end of the first moving block 516 is movably connected to the outer surface of the first sliding rod 517, and the top of the first sliding rod 517 is fixedly connected to the center of the support frame 511, a cutting block 518 is provided at the bottom of the first moving block 516, and the bottom of the first moving block 516 is fixedly connected to the top of the cutting block 518, a translation device 52 is provided at the bottom of the cutting block 518, and the motor 512 is set on the support The top of the support frame 511 facilitates the movement of the movable rods 514 connected at both ends driven by the motor 512. When the movable rods 514 swing downward under the drive of the motor 512, they drive one end of the elliptical plate 515, which is movably connected at the bottom, to move downward synchronously. At this time, the first movable block 516 connected to the other end of the elliptical plate 515 will slide downward along the first sliding rod 517, driving the cutting block 518 fixedly connected to the bottom of the first movable block 516 to move toward the cable tray blank until it is cut to a preset length. During the sliding process, the rear end protrusion of the first movable block 516 cooperates with the first sliding rod 517 to ensure that the cutting block 518 moves along the preset track, ensuring cutting accuracy. The bottom of the cutting block 518 is correspondingly connected to the top of the translation device 52.

[0020] The translation device 52 includes a telescopic column 521, and curved rods 522 are provided on both sides of the top of the telescopic column 521, and the two sides of the top of the telescopic column 521 are movably connected to one end of the curved rod 522, a swing rod 523 is provided on the outside of the other end of the curved rod 522, and the outside of the other end of the curved rod 522 is movably connected to the top groove of the swing rod 523, a connecting block 524 is provided at the bottom groove of the swing rod 523, and the bottom groove of the swing rod 523 is movably connected to the top of the connecting block 524, and a second moving block 524 is provided at the bottom of the connecting block 524 Block 525 is constructed by installing a curved rod 522 at the top of a telescopic column 521. When the telescopic column 521 is extended and retracted by the motor 512, it pushes the curved rods 522 movably connected to the top and bottom. Since the curved rods 522 are V-shaped, when one end is pushed, the center, supported by the raised portion of the support base 528, causes the other end to tilt downward, thereby driving the movement of a swing rod 523 movably connected to the other end of the curved rod 522. As the curved rod 522 tilts, the swing rod 523 can achieve a pushing operation. The bottom of the connecting block 524 is fixedly connected to one end of the top of the second movable block 525.

The second sliding rod 527 is provided at the groove at the bottom of the second moving block 525, and the groove at the bottom of the second moving block 525 is movably connected to the outer surface of the two second sliding rods 527. The bottom of the two second sliding rods 527 is provided with a supporting base plate 528, and the bottom of the second sliding rod 527 is fixedly connected to the two ends of the top of the supporting base plate 528. Placement platforms 529 are provided on both sides of the top of the supporting base plate 528, and the two sides of the top of the supporting base plate 528 are connected to the placement platform 529. 529 is fixedly connected to the bottom of the cutting block 518. The top of the placement table 529 is correspondingly connected to the bottom of the cutting block 518. By connecting the bottom of the curved rod 522 to the top of the connecting block 524, when the swing rod 523 pushes the connecting block 524 to move, the second movable block 525 fixedly connected to the bottom of the connecting block 524 slides horizontally along the outer surfaces of the two second sliding rods 527, ensuring the accuracy of the motion trajectory. When the second movable block 525 slides forward, it drives the push block 526 fixedly connected to the other end of the top synchronously forward, thereby pushing the cut cable tray model placed on the top of the placement table 529 toward the center of the polishing device 53. Because the groove structure at the bottom of the push block 526 forms a guiding fit with the raised portion on the top of the placement table 529, the smooth pushing process is ensured, achieving precise positioning and transportation of the cable tray model. The bottom end of the placement table 529 is correspondingly connected to the outside of the polishing device 53.

[0022] The grinding device 53 includes a long strip 531, a double-axis cylinder 532 is provided at the top center of the long strip 531, and the top center of the long strip 531 is fixedly connected to the bottom of the double-axis cylinder 532, concave blocks 533 are provided at the output shafts at both ends of the double-axis cylinder 532, and the output shafts at both ends of the double-axis cylinder 532 are fixedly connected to the rear end of the concave blocks 533, hollow blocks 534 are provided at the grooves of the two concave blocks 533, and the grooves of the two concave blocks 533 are movably connected to the groove parts at both ends of the hollow blocks 534, and the bottoms of the two hollow blocks 534 are connected to the top of the long strip 531.

[0023] The top of the two hollow blocks 534 is provided with a second rotating shaft 535, and the top of the two hollow blocks 534 is movably connected to the two ends of the second rotating shaft 535, the outer surface of the center of the two second rotating shafts 535 is provided with a pushing block 536, and the outer surface of the center of the two second rotating shafts 535 is fixedly connected to the inside of the pushing block 536, and the convex parts at the bottom of the two pushing blocks 536 are movably connected to the convex parts of the concave blocks 533, and the top of the two pushing blocks 536 is provided with a grinding block 537. A concave block 533 is provided at the output shaft end of the dual-axis cylinder 532. When the dual-axis cylinder 532 is driven, it drives the concave block 533 and the hollow block 534 movably connected to its groove. When the dual-axis cylinder 532 retracts, the concave block 533 pulls the push block 536 toward the center. At this time, the second rotating shaft 535 inside the push block 536 rotates under the support of the hollow block 534, thereby driving the top grinding block 537 to deflect to the sides, allowing the cable tray model to be placed on the positioning protrusions on the top of the dual-axis cylinder 532. When the dual-axis cylinder 532 extends, the concave block 533 pulls the raised portions of the two push blocks 536 back to their original positions along a preset trajectory, completing the surface treatment of the cable tray model. The tops of the two push blocks 536 are movably connected to the rear ends of the grinding block 537.

[0024] The working principle of the present invention is as follows: During operation, the base 1 provides a stable support for the entire device, ensuring that the cutting device 5 can perform different processing steps. The movable device 51 includes a motor 512. When the motor 512 is started, it drives the rotation of the first rotating shafts 513 on both sides, thereby driving the movable rod 514 connected to the bottom of the first rotating shaft 513 to swing downward, and then pulls the elliptical plate 515 connected to the bottom to push the first moving block 516 to slide downward along the first sliding rod 517. During the movement, the cutting block 518 fixed to the bottom of the first moving block 516 also moves accordingly, cutting the cable tray blank to a preset length. After the cutting is completed, the translation device 52 starts to operate. The telescopic column 521 in the translation device 52 will be extended and retracted up and down under the drive of the motor 512, and connected to push the movement of one end of the curved rod 522 on both sides of the top. By utilizing the flipping characteristics of its V-shaped structure, it can drive the movement of the swing rod 523 connected to the other end. At this time, the swing rod 523 will quickly push the connecting block 524, so that the second moving block 525 fixedly connected to the bottom of the connecting block 524 can slide horizontally along the outer surface of the second sliding rod 527. When the second moving block 525 slides forward, it will drive the push block 526 fixedly connected to the other end of the top to move forward synchronously, and the cut bridge frame model placed on the placement table 529 will be accurately transferred to the top of the grinding device 53. The grinding device 53 includes a double-axis cylinder 532. When the double-axis cylinder 532 contracts, it drives the concave block 533 connected to the output shaft end and the internal hollow block 534 to move. At this time, the pushing block 536 rotates under the support of the second rotating shaft 535, so that the grinding block 537 connected to the top of the pushing block 536 can be offset to both sides, which is convenient for placing the bridge model; after the bridge is in place, the double-axis cylinder 532 extends again, and the concave block 533 pulls the protruding part of the pushing block 536 back to its original position. The grinding block 537 polishes the edge of the bridge by double-sided grinding to eliminate cutting burrs and improve surface quality. Subsequently, the cable bridge after cutting and polishing will be pushed to the top of the groove block 4 and processed. By utilizing the mutual cooperation between the extrusion plate 3 on the top of the forming device 2 and the groove block 4, the cable bridge placed on the top of the groove block 4 will be initially pressed into the groove through a downward pressing action to complete the basic shape shaping; at this time, the pulling component 31 in the hollow area in the middle of the extrusion plate 3 starts to operate, and through lateral movement, the half-extruded cable bridge model is pulled backward in the horizontal direction, realizing the segmented molding of the entire bridge model, ensuring the dimensional accuracy of each bridge section.
