Description

Technical Field

[0001] This utility model relates to the field of cable trays, and in particular to a forming device for processing cable tray bends. 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 and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] When laying cables, they are usually bent according to the shape and structure of the building. This means that cable trays need to be installed using cable tray bend structures, so that the laying path of the cable trays can be bent as needed.

[0004] Cable tray elbows have a more complex shape than straight cable trays. They are composed of a base plate, two side plates, and a top plate. Therefore, during the production and processing of cable tray elbows, the two side plates of the cable tray elbow need to be bent to correspond to the shape of the base plate, so that the two side plates correspond to the shape of the cable tray elbow. Then, the two side plates need to be welded to the base plate. Finally, the top plate is fixed to the upper end of the two side plates to complete the formation of the cable tray elbow. This process requires multiple devices to work together to produce a batch of cable tray elbows, which can easily lead to a longer production time for a batch. Utility Model Content

[0005] The purpose of this invention is to provide a forming device for processing cable tray elbows in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A forming device for processing cable tray elbows includes an operating table, a fixed structure installed at the lower end of the operating table, and a forming mechanism.

[0008] The forming mechanism includes a base with a placement groove at the top and an elbow base plate placed in the middle of the groove. A first bending frame is provided at the top of the base, and a second bending frame is provided in front of the first bending frame. A drive structure for adjusting the distance between the first and second bending frames is installed at the lower ends of the first and second bending frames. A gantry frame is provided around the base and is fixed to the operating table. An electric push rod is installed at the top of the gantry frame, and a contour frame is installed at the telescopic end of the electric push rod. Multiple welding heads are evenly installed on the edges of the lower end of the contour frame.

[0009] Preferably, the corresponding ends of the first bending frame and the second bending frame are both designed to fit the outer shape of the placement groove.

[0010] Preferably, the shape and dimensions of the profile frame correspond to the bottom plate of the elbow.

[0011] Preferably, the drive structure includes a double-segment screw, which is rotatably connected inside the base. A motor is installed at the input end of the double-segment screw, and sliders are threadedly connected to the periphery of the two threaded segments of the double-segment screw. The first bending frame and the second bending frame are respectively fixed to the upper ends of the two sliders.

[0012] Preferably, the two sections of the double-screw have opposite thread directions, and the slider is slidably connected to the base.

[0013] Preferably, the fixing structure includes two base frames, which are fixed to the lower end of the operating table, and multiple fixing bolts are provided in the middle of the base frames.

[0014] The advantages compared to existing technologies are as follows:

[0015] During operation, the device first activates the electric actuator, causing the profile frame to move down and press onto the elbow base plate. Then, the two prepared side plates are placed at the corresponding ends of the first and second bending frames, respectively. After preparation, the drive structure simultaneously pushes the two side plates towards the profile frame. Once the side plates contact the profile frame, they are bent to correspond to the elbow base plate. This not only bends the side plates but also fixes their position relative to the elbow base plate. Subsequently, the welding head welds and fixes the gap between the side plates and the bottom of the elbow base plate. This allows the device to form the cable tray elbow in a short time, making the production of cable tray elbows faster and more efficient. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a forming device for processing cable tray elbows includes an operating table 1, a fixed structure installed at the lower end of the operating table 1, and a forming mechanism.

[0026] The fixed structure includes two base frames 11, which are fixed to the lower end of the operating table 1. Multiple fixing bolts 12 are provided in the middle of the base frames 11. The fixing bolts 12 can be used to fix the device in a suitable position.

[0027] The forming mechanism includes a base 2, with a placement groove 21 at the upper end of the base 2. A bent base plate 22 is placed in the middle of the placement groove 21. A first bending frame 26 is provided at the upper end of the base 2, and a second bending frame 27 is provided in front of the first bending frame 26. A drive structure for adjusting the distance between the first bending frame 26 and the second bending frame 27 is installed at the lower end of the first bending frame 26 and the second bending frame 27. The drive structure includes a double-segment screw 23, which is rotatably connected inside the base 2. A motor 24 is installed at the input end of the double-segment screw 23. Slider 25s are threadedly connected to the periphery of the two threaded segments of the double-segment screw 23. The two threads of the double-segment screw 23 have opposite directions of rotation. The slider 25s are slidably connected to the base 2. The first bending frame 26... The first bending frame 26 and the second bending frame 27 are respectively fixed to the upper ends of the two sliders 25. The corresponding ends of the first bending frame 26 and the second bending frame 27 are respectively placed in the outer shape of the slot 21. A portal frame 28 is provided on the periphery of the base 2, and the portal frame 28 is fixed to the operating table 1. An electric push rod 29 is installed on the upper end of the portal frame 28. A contour frame 210 is installed on the telescopic end of the electric push rod 29. The outer shape and size of the contour frame 210 correspond to the elbow base plate 22. Multiple welding heads 211 are evenly installed on the lower edge of the contour frame 210. Through the threaded connection between the two sliders 25 and the double-segment screw 23 and the sliding connection between the sliders 25 and the base 2, the distance between the two sliders 25 can be adjusted when the motor 24 drives the double-segment screw 23 to rotate.

[0028] Working principle: During device operation, the prepared elbow base plate 22 is first placed in the placement slot 21. After placement, the electric actuator 29 is activated to press the lower end of the contour frame 210 against the upper end of the elbow base plate 22. Then, the two prepared side plates are placed at the corresponding ends of the first bending frame 26 and the second bending frame 27, respectively. At the same time, the motor 24 is activated. Through the threaded connection between the two sliders 25 and the double-segment screw 23, and the sliding connection between the sliders 25 and the base 2, when the motor 24 drives the double-segment screw 23 to rotate, the first bending frame 26 and the second bending frame 27 on the two sliders 25 can push the two side plates towards the contour frame 210. Once the side plates contact the contour frame... After step 210, the side plate can be bent to correspond to the elbow base plate 22. This not only bends the side plate but also fixes its position to correspond to the elbow base plate 22. Then, the welding head 211 welds and fixes the bottom gap between the side plate and the elbow base plate 22. This allows the device to form the cable tray elbow in a short time, making the production of cable tray elbows faster and more efficient. After processing is completed, the motor 24 drives the double-segment screw 23 in the opposite direction, thereby resetting the first bending frame 26 and the second bending frame 27. At the same time, the electric push rod 29 is activated to reset the contour frame 210. Then, the formed cable tray elbow structure can be taken out.
