Description

Technical Field

[0001] This utility model belongs to the field of cable tray production and processing technology, and in particular relates to a continuous bending die for cable tray metal plates. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or attached to various building and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. This applies to cable trays installed outdoors. A search revealed patent application number 201922130729.1, which discloses a bending mold for trough-type large-span cable trays. The mold includes a press, an upper module, and a lower module. The upper module is driven vertically by the press to open and close with the lower module. The upper module has a flat-push bending mechanism on each of its two long sides.

[0003] However, in actual use, the applicant found that when bending the two ends of the cable tray metal plate horizontally, it is necessary to drive the horizontal bending strip to bend the metal plate through multiple horizontal hydraulic push rods. Moreover, the multiple horizontal hydraulic push rods are all set between the horizontal bending strip and the upper module. Due to space limitations, it is inconvenient for personnel to perform maintenance operations on the horizontal hydraulic push rods. In view of this, we propose a continuous bending die for cable tray metal plates. Utility Model Content

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses a continuous bending die for cable tray metal plates. By driving a hydraulic push rod, the drive plate moves to the right, causing the rollers to roll along the inclined surface of the guide block. This causes the guide arms on both sides, along with the horizontal bending strips, to move away from the upper die base. Thus, the two ends of the cable tray metal plate can be bent horizontally by the horizontal bending strips on both sides, eliminating the need for multiple hydraulic push rods to drive the horizontal bending strips. Furthermore, the hydraulic push rod is located on one side of the upper die base, making maintenance easier. By manually rotating the shaft counterclockwise, the cam rotates, which in turn lifts the lifting plate upwards. This allows the bent cable tray to be lifted, making it easier for personnel to remove the cable tray from the bending groove, resulting in better performance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A continuous bending die for cable tray metal plates includes a base 1. An L-shaped support frame 3 is fixedly connected to the top of the base 1. A hydraulic push rod 2 5 is fixedly installed on the top of the L-shaped support frame 3. The telescopic end of the hydraulic push rod 2 5 passes through the top of the L-shaped support frame 3 and is fixedly connected to a connecting plate 7. Guide posts are symmetrically arranged on the top of the connecting plate 7 for guiding the connecting plate 7. An upper die base 8 is fixedly connected to the bottom of the connecting plate 7. Horizontal bending strips 81 are symmetrically elastically connected to the front and rear sides of the upper die base 8 by springs 86. Receiving grooves 82 for receiving the horizontal bending strips 81 are symmetrically opened on the front and rear sides of the upper die base 8. A hydraulic push rod 1 4 is fixedly installed on one side of the upper die base 8. A controller 6 is fixedly installed on the front side of the support frame 3. The controller 6 is electrically connected to an external power supply via a wire. Hydraulic push rod 4 and hydraulic push rod 5 are respectively electrically connected to the controller 6 via wires. The telescopic end of hydraulic push rod 4 is fixedly connected to one end of the drive plate 83 inside hydraulic push rod 4. The upper mold base 8 has a guide groove inside for guiding the drive plate 83, so that the drive plate 83 can move left and right under the drive of hydraulic push rod 4. Guide inclined blocks 831 are symmetrically fixedly installed side by side at equal intervals on the front and rear sides of the drive plate 83. Guide arms 84 are fixedly connected side by side at equal intervals on the inner wall of the horizontal bending strip 81. The end of the guide arm 84 away from the horizontal bending strip 81 A roller 841 extends into the interior of the upper mold base 8 and is rotatably connected to it via an axle. The roller 841 rolls along the inclined surface of the guide ramp 831, which is higher on the left and lower on the right. A guide rod 85 is fixedly connected to the horizontal bending strip 81 between two adjacent guide arms 84. One end of the guide rod 85, away from the horizontal bending strip 81, extends into the interior of the upper mold base 8 and is fixedly provided with a limit plate 851. A spring 86 is sleeved on the guide rod 85, with one end of the spring 86 abutting against the upper mold base 8 and the other end of the spring 86 abutting against the limit plate 851. A lower mold base 2 is fixedly connected to the top of the base 1 below the upper mold base 8. A bending groove 21 is provided at the top. U-shaped limiting strips 22 are symmetrically fixed on the top of the lower mold base 2 on both sides of the bending groove 21. The openings of the two U-shaped limiting strips 22 are opposite each other. By driving the hydraulic push rod 4, the drive plate 83 is moved to the right, which allows the roller 841 to roll along the inclined surface on the guide block 831. This causes the guide arms 84 on both sides, together with the horizontal bending strips 81, to move away from the upper mold base 8. Thus, the two ends of the cable tray metal plate can be bent horizontally by the horizontal bending strips 81 on both sides without the need for multiple hydraulic push rods to drive the horizontal bending strips 81. Furthermore, the hydraulic push rod 4 is located on one side of the upper mold base 8, which makes maintenance easier.

[0022] A lifting plate 9 is placed at the bottom of the bending groove 21. A stepped groove 23 is formed at the bottom of the bending groove 21. The lifting plate 9 is inserted into the stepped groove 23, and the top of the lifting plate 9 is flush with the bottom of the bending groove 21. Guide vertical plates are symmetrically arranged at the bottom of the lifting plate 9, and the guide vertical plates slide along the side wall of the inner groove formed inside the lower mold base 2 to guide the lifting plate 9, so that the lifting plate 9 can move up and down and prevent the lifting plate 9 from deviating, so that the lifting plate 9 can fall smoothly into the step. In groove 23, a rotating shaft 10 is rotatably connected to the lower mold base 2 below the lifting plate 9 via a bearing. A cam 11 is fixedly sleeved on the rotating shaft 10. The front end of the rotating shaft 10 extends to the outside of the lower mold base 2 and is fixedly provided with a handle 101. By manually rotating the rotating shaft 10 counterclockwise, the cam 11 is driven to rotate, which can lift the lifting plate 9 upward through the cam 11. Thus, the bent cable tray can be lifted by the lifting plate 9, making it easier for personnel to remove the cable tray from the bending groove 21, resulting in better performance.

[0023] Working principle: In use, the metal plate of the cable tray to be bent is placed on top of the lower die base 2 between the two U-shaped limit bars 22. The controller 6 drives the hydraulic push rod 2 5 to move the connecting plate 7 and the upper die base 8 downward. Through the cooperation of the upper die base 8 and the bending groove 21, the metal plate can be vertically bent. Then, the controller 6 can drive the hydraulic push rod 4 to move the drive plate 83 to the right. At this time, the drive plate 83 drives the guide inclined block 831 to move to the right, which allows the roller 841 to roll along the inclined surface on the guide inclined block 831, and drives the guide arm 84 together with the horizontal bending bar 81 to move away from the upper die base 8. The horizontal bending bars 81 on both sides can be used to horizontally bend the front and rear ends of the vertically bent metal plate. During the process, the movement of the horizontal bending strip 81 can drive the guide rod 85 and the limiting plate 851 to move outward and compress the spring 86. After the horizontal bending is completed, the reverse drive hydraulic push rod 4 drives the drive plate 83 to move to the left to reset. At this time, under the elastic force of the spring 86, the horizontal bending strip 81 can be driven to move towards the upper mold base 8 to reset and the horizontal bending strip 81 can be re-stored in the bending groove 21. Then, the reverse drive hydraulic push rod 5 drives the connecting plate 7 and the upper mold base 8 to move upward to reset. Finally, the handle 101 is held to drive the rotating shaft 10 and the cam 11 to rotate counterclockwise. The cam 11 can lift the lifting plate 9 and lift the bent cable tray through the lifting plate 9, so that the cable tray can be easily removed from the bending groove 21.
