Description

Technical Field

[0001] The present invention relates to the field of cutting facilities, and particularly to a cutting device for the side plates of a compact busbar trunking. Background Art

[0002] The side plates of a compact busbar trunking are an important part of the busbar trunking. As a component of the outer shell of the busbar trunking, the side plates can protect the internal busbars, insulating materials, etc. from the influence of external environmental factors.

[0003] The side plates of the busbar trunking need to be bent at the edges after cutting to ensure that they can be assembled on both sides of the busbar trunking in the later stage. Since the busbar trunking often changes direction during layout, or due to the need to avoid water pipes, air ducts, building beams, etc. during layout, the lengths of the busbar trunkings to be produced vary greatly. Therefore, the material plates for producing the side plates need to be cut into various plates of different sizes during the cutting process. In the prior art, during the cutting process of the material plates, only one material plate can be cut at a time, and the number of single cuts is small, resulting in low cutting efficiency. At the same time, only a material plate of a single length can be cut in one cut, and material plates of different lengths cannot be cut, resulting in large cutting limitations. Frequent adjustment and loading / unloading of the material plates are not suitable for the cutting of the side plates of the busbar trunking. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the background art, and to propose a cutting device for the side plates of a compact busbar trunking.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a cutting device for the side plates of a compact busbar trunking, including a bench.

The pressure plate ear is screwed onto the outer surface of the first adjusting screw. Convex ribs extend from the front and rear ends inside the limit frame. The convex ribs fit through the front and rear end faces of the pressure plate ear.

[0007] Preferably, on the lower part of the opposite surfaces of the two limiting frames and on the lower parts of the front and rear end faces of the adjusting pressing seat, connecting frames are both extended. At the lower end of the connecting frame, a limiting post is fixedly installed. On the outer surface of the limiting post, an L-shaped seat is fitted. The end of the L-shaped seat is fixed to the lower end of the cutting table. A return spring is wound around the outer side of the limiting post. The upper end of the return spring is fixed to the connecting frame, and the lower end of the return spring is fixed to the upper end of the L-shaped seat. At the lower end of the limiting post, a limiting cap is coaxially inlaid. The limiting cap fits against the lower end of the L-shaped seat.

[0008] Preferably, the fixing member includes a second adjusting screw column rotatably installed at the upper end of the adjusting pressing seat. A threaded sleeve is screwed onto the outer surface of the second adjusting screw column. At the lower end of the threaded sleeve, a bearing plate is fixedly installed. A plurality of top ears are linearly arrayed and extended on the side surface of the bearing plate. The top ears penetrate through the side surface of the adjusting pressing seat. The top ears are slidably matched with the adjusting pressing seat. The end of the top ear presses tightly against the side surface of the adjusting plate.

[0009] Preferably, the cutting and pressing member includes a push knife table installed at the upper end of the table frame. On one side of the upper end of the push knife table, a cutting shaft is installed. At the front end of the cutting shaft, a cutting knife is coaxially fixedly installed. On the other side of the upper end of the push knife table, a cutting motor is fixedly installed. The output end of the cutting motor is connected to the cutting shaft.

[0010] Preferably, two shaft seats are symmetrically and rotatably installed on the outer surface of the cutting shaft. The lower end of the shaft seat is fixed to the upper end of the push knife table. At the rear end of the cutting shaft and at the output end of the cutting motor, belt pulleys are both coaxially fixedly installed. A synchronous belt is connected between the two belt pulleys. At the front and rear edges of the lower end of the push knife table, sliders are both extended. A guide rod is slidably installed through the inside of the slider. The end of the guide rod is fixed to the table frame.

[0011] Preferably, a threaded rod is screwed at the middle of the lower end of the push knife table. The threaded rod is rotatably installed at the upper end of the table frame. A servo motor is fixedly installed on the side surface of the table frame. The output end of the servo motor is fixed to the threaded rod. At the upper ends of the two shaft seats, a shaft frame is fixedly installed. The front end of the cutting shaft is rotatably connected to the shaft frame.

The end of the pressing rail is in contact with the wheel body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By sequentially stacking multiple material plates on the cutting table, at this time, the limiting frames are attached to both sides of the material plates, so that the multiple material plates are neatly stacked together. At the same time, the rear ends of the multiple material plates respectively abut against multiple fixed plate strips, so that the multiple material plates can be in a stepped shape. Subsequently, the cutting knife can be used to cut the multiple material plates simultaneously and cut out material plates of different lengths, thereby improving the cutting efficiency and reducing the cutting limitations.

[0015] 2. By directly rotating the second adjusting stud, the threaded sleeve can be driven to move, so that the top ears on the bearing plate can be separated from the adjusting plate, and the multiple adjusting plates can move without the top tightening of the top ears, so as to adjust the positions of the multiple fixed plate strips to meet the cutting requirements of different cutting lengths.

[0016] 3. When the cutting knife is driven to cut, the pressing rail will move synchronously. At this time, the wheel body will roll on the inclined surface of the pressing rail to drive the T-shaped frame to move down a certain distance, and then drive the limiting frame, the pressing plate ears and the pressing strips on the adjusting pressing seat to move down to press on the multiple material plates, so as to fix the multiple material plates by itself. The process does not require manual fixing by workers, thus effectively facilitating the cutting. Brief Description of the Drawings

Then stack multiple material plates 37 on the cutting table 2 in sequence. At this time, the limiting frame 14 is attached to both sides of the material plates 37, so that multiple material plates 37 are neatly stacked together. At the same time, the rear ends of multiple material plates 37 respectively abut against multiple fixed plate strips 31, so that multiple material plates 37 can be in a stepped shape. Subsequently, the servo motor 3 works to drive the threaded rod 5 to rotate, so that the push knife table 6 screwed on the threaded rod 5 can move. At this time, the slider 26 slides on the guide rod 4 to guide the push knife table 6. At the same time, the cutting motor 7 drives the cutter 11 on the cutting shaft 8 to rotate through the synchronous belt 24, so as to drive the moving push knife table 6 to drive the rotating cutter 11 to move towards the position where the material plates 37 are located. During this process, the push knife table 6 will also drive the pressing rail 13 to move synchronously. At this time, the wheel bodies 22 will roll on the inclined surface of the pressing rail 13 to drive the T-shaped frame 16 to move down a certain distance, and then drive the limiting frame 14, the pressing plate ear 27 and the pressing strip 30 on the adjusting pressure seat 15 to move down to press on multiple material plates 37 to fix multiple material plates 37 by itself. Subsequently, the cutter 11 continues to move to contact the material plates 37 to cut multiple material plates 37 at the same time, and cut out material plates 37 of different lengths in one cut to meet the cutting requirements.
