Description

Technical Field

[0001] This utility model belongs to the field of cutting machine technology, and in particular relates to an adjustable-angle cable tray cutting machine. Background Technology

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building structures and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors after galvanizing are typically handled by cable tray cutting machines, which are specialized equipment for cutting cable trays (metal wire troughs, cable trays, etc.). They are commonly used in building electrical engineering and automated wiring applications for precise cutting, drilling, or bending of cable trays before pre-treatment.

[0003] Electrical wiring within a building needs to pass through walls, beams, columns, corners, and other locations. Cable trays need to be cut at specific angles to achieve turns or branch connections. For example, when a cable tray needs to turn along a corner, cutting at the front and back angles allows for a smooth splicing of two sections. There are also cable trays that require vertical differences, which need to be cut at the top and bottom angles.

[0004] Currently, the cutting angle of cable tray cutting machines is fixed. The required angle can only be cut by adjusting the angle of the cable tray. When the cable tray is long, a large space is required to adjust the angle, which makes the operation difficult. In order to facilitate multi-angle cutting of cable trays, we have designed an adjustable angle cable tray cutting machine. The cutting angle can be adjusted as needed, which is suitable for various cutting scenarios of cable trays and has high adaptability. Utility Model Content

Through the cooperation of the limiting rail 5 and the strip-shaped pads 6, the strip-shaped pads 6 can move on the surface of the limiting rail 5, and the distance between the two strip-shaped pads 6 can be adjusted as needed. This is suitable for various angle cutting scenarios. Furthermore, the two strip-shaped pads 6 can also support the cable tray, preventing damage to the cutting platform 2 during cutting. An angle adjustment assembly 3 is provided on the rear side of the top of the steel frame 1. The angle adjustment assembly 3 includes a connecting seat plate 31 fixedly installed on the rear side of the top of the steel frame 1. Two symmetrical semicircular plates 32 are fixedly connected to the top of the connecting seat plate 31, and the two semicircular plates 32 are fixedly spaced apart. A fan-shaped worm gear 33 is connected to the top of two semi-circular plates 32, and a U-shaped sleeve 34 is fitted on the top. The inner cavity of the U-shaped sleeve 34 is provided with a rotatable worm 36, which meshes with the fan-shaped worm gear 33. A cutting assembly 4 is provided on the top of the U-shaped sleeve 34. The cutting assembly 4 includes a fixed connecting seat 41 fixedly installed on the top of the U-shaped sleeve 34. A rotating shaft frame 42 is fixedly installed on one side of the fixed connecting seat 41. A load-bearing swing arm 43 is rotatably connected to the inner cavity of the rotating shaft frame 42 through a rotating shaft. A cutting machine 44 is installed at the end of the load-bearing swing arm 43. A cylinder 45 is fixedly installed on one side of the fixed connecting seat 41. A connecting seat 46 is fixedly installed at the output end of the cylinder 45. A pull rod 47 is installed between the connecting seat 46 and the load-bearing swing arm 43. A connecting pin 48 is fixedly connected to both the load-bearing swing arm 43 and the connecting seat 46. Both ends of the pull rod 47 are rotatably connected to the surface of the connecting pin 48.

[0025] Reference Figure 1-3Guide pins 37 are provided through the front and rear sides of the U-shaped sleeve 34. An arc-shaped elongated hole 38 is opened on one side of the semi-circular plate 32 for the guide pins 37 to slide. Through the cooperation of the guide pins 37 and the arc-shaped elongated hole 38, the U-shaped sleeve 34 will drive the guide pins 37 to slide in the inner cavity of the arc-shaped elongated hole 38 during rotation, providing limit and guidance for the movement of the U-shaped sleeve 34, ensuring that the U-shaped sleeve 34 will not detach from the surface of the two semi-circular plates 32, and improving the rotational stability of the U-shaped sleeve 34. Two base blocks 35 are fixedly installed on the top of the inner cavity of the U-shaped sleeve 34. A worm gear 36 is rotatably connected between the two base blocks 35. One end of the worm gear 36 passes through to the outside of the U-shaped sleeve 34 and is fixedly installed. Equipped with a swivel lever 39, the user can operate the worm gear 36 by using a ratchet wrench on the swivel lever 39, providing a force point for the user to operate the worm gear 36 and providing convenience. The U-shaped sleeve 34 has an indicator groove 310 in the middle of the front and rear sides. An angle scale 311 is provided on the opposite side of the two semicircular plates 32. Through the cooperation of the indicator groove 310 and the angle scale 311, the U-shaped sleeve 34 will move the indicator groove 310 during rotation. The indicator groove 310 can point to the angle scale 311 on the surface of the semicircular plate 32 to determine the rotation angle of the U-shaped sleeve 34 at this time, and thus determine the adjustment angle of the cutting component 4.

[0026] Working principle: When using this utility model, the user picks up the ratchet wrench and operates the worm 36 to rotate on the surface of the plum blossom bar 39. The worm 36 rotates on the fixed sector worm wheel 33, which in turn drives the U-shaped sleeve 34 to rotate through the base block 35. The U-shaped sleeve 34 then drives the guide pin 37 to slide in the inner cavity of the arc-shaped elongated hole 38, providing stability for the rotation of the U-shaped sleeve 34. The U-shaped sleeve 34 adjusts the tilt angle of the cutting component 4. The tilt angle of the cutting component 4 can be seen by pointing to the angle scale 311 through the indicator groove 310 on the U-shaped sleeve 34. The worm wheel 33 and the worm 36 themselves... It has a self-locking function and will not rotate when the worm gear 36 is not under force. When cutting, simply place the cable tray above the two strip pads 6 and press it to limit the cable tray. Then, control the cylinder 45 to extend, so that the connecting seat 46 pulls the pull rod 47. The pull rod 47 then pulls the load-bearing swing arm 43 to rotate downward around the inner shaft of the rotating shaft frame 42. The load-bearing swing arm 43 drives the cutting machine 44 to rotate downward to cut the cable tray at an angle. During the fixing of the cable tray, the placement of the cable tray can be switched to achieve cutting at the front-back or up-down angles.

[0027] In summary, this adjustable-angle cable tray cutter, by operating the worm gear 36 to rotate forward and reverse, in conjunction with the fixed sector worm wheel 33, causes the U-shaped housing 34 to rotate and drives the cutting assembly 4 to adjust its angle. After the angle adjustment is completed, the cylinder 45 extends, causing the pull rod 47 to pull the load-bearing swing arm 43 to rotate, thereby moving the cutting machine 44 in the working state towards the cable tray at the top of the steel frame 1, cutting the cable tray at the required angle. This achieves the goal of adjustable cutting angle, making it suitable for various cutting scenarios of cable trays and highly adaptable.

[0028] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
