Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of thin plate bending devices, and in particular to a thin plate bending device. Background Technology
[0002] In the field of metal processing, it is often necessary to bend steel plates into the required shapes, which requires the use of bending machines and spring machines. Currently, most bending devices are manually loaded. In order to improve the working efficiency of bending devices, many companies are conducting research and development on high-speed and high-reliability steel plate bending devices.
[0003] Currently, when loading and unloading thin sheet metal bending equipment, if traditional manual loading methods are used, the working efficiency of the bending equipment will be determined by the loading speed, and the efficiency of the high-speed and high-reliability thin sheet metal bending equipment cannot be brought into play. Utility Model Content
[0004] Therefore, it is necessary to provide a thin plate bending device to address the technical problem of low bending efficiency caused by slow manual operation during the loading and unloading of the aforementioned thin plate bending device.
[0005] To achieve the above objectives, this utility model provides a thin plate bending device, including a frame and a bending mechanism. A conveyor is mounted on the frame, a fixed block is mounted on the conveyor, a rotating block is mounted on the fixed block, a spring is installed inside the fixed block, and the output end of the spring is connected to the rotating block. A limiting groove is provided on the frame, and the rotating block is slidably engaged in the limiting groove. A V-groove is provided on the frame, which is configured to cooperate with the bending mechanism. Several ejection grooves are provided in the V-groove, and push blocks are slidably engaged in the ejection grooves. A spring is installed in the ejection groove, and the output end of the spring is connected to the push block. A pressure plate is mounted on the conveyor, and a pressure plate is slidably engaged in the frame. An air bladder is mounted on the frame, and the output end of the air bladder is located on one side of the V-groove.
[0006] Preferably, the depth of the ejection groove increases with the distance from the airbag output end.
[0007] Preferably, the number of airbags can be increased as the weight of the sheet increases.
[0008] Preferably, an output receiving platform is installed on the frame.
[0009] Preferably, a ventilator is installed on the frame, with the inlet end of the ventilator connected to the airbag and the outlet end of the ventilator located on one side of the V-groove.
[0010] Preferably, both pressure plate one and pressure plate two are chamfered, and several universal balls are rotatably mounted on pressure plate one.
[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:
[0012] 1. By sliding the rotating block in the limiting groove, the rotating block can push the material placed above the limiting groove. After pushing it to the appropriate position, the rotating block collides and bends with the frame and is driven by the conveyor to rotate for the next push and feeding, thereby improving the feeding efficiency.
[0013] 2. While the conveyor drives the rotating block to rotate, it also drives the pressure plate to rotate. The pressure plate can squeeze and spray air through the pressure plate, so that the bent thin plate material can be pushed up by the push block and blown out quickly, thereby improving the feeding efficiency.

Detailed Implementation
[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0020] Please see Figures 1 to 4This application provides a thin plate bending device, including a frame 1 and a bending mechanism 101. The bending mechanism 101 can bend the thin plate by cooperating with a V-groove 6 after descending. A conveyor 2 is installed on the frame 1. The conveyor 2 can be a belt conveyor with a built-in motor or a double-row chain conveyor as in the prior art. When a belt conveyor is selected, the fixing block 3 and the pressure plate 10 are directly installed on the belt. When a double-row chain conveyor is selected, the fixing block 3 and the pressure plate 10 are fixedly installed on the connecting rods directly installed on the two rows of chains. A fixing block 3 is fixedly installed on the conveyor 2, and a rotating block 4 is rotatably installed on the fixing block 3. A spring is installed inside the fixing block 3, and the output end of the spring is connected to the rotating block 4. Next, a limiting groove 5 is provided on the frame 1, and the rotating block 4 is slidably engaged in the limiting groove 5. A V-shaped groove 6 is provided on the frame 1, and the V-shaped groove 6 is configured to cooperate with the bending mechanism 101. Several push-out grooves 7 are provided in the V-shaped groove 6, and push blocks 8 are slidably engaged in the push-out grooves 7. A spring 9 is fixedly installed in the push-out grooves 7, and the output end of the spring 9 is connected to the push block 8. A pressure plate 10 is fixedly installed on the conveyor 2, and a pressure plate 11 is slidably engaged in the frame 1. The pressure plate 11 is preferably made of a lighter material. The pressure plate 11 can be slidably engaged in the frame 1 by the sliding engagement of the locking block and the locking groove. An airbag 12 is fixedly installed on the frame 1, and the output end of the airbag 12 is located on one side of the V-shaped groove 6.
[0021] In this embodiment, the bent sheet material can be placed above the limiting groove 5. When the conveyor 2 drives the rotating block 4 on the fixed block 3, the portion of the rotating block 4 protruding from the limiting groove 5 can push the sheet above the V-groove 6. The rotating block 4 can cooperate with the frame 1 to limit the sheet. During limiting, the rotating block 4 also collides with the frame 1 of the limiting groove 5, causing it to be squeezed and deflected, allowing it to continue rotating with the conveyor 2 for the next feeding. After the rotating block 4 no longer abuts against the frame 1, the spring on the fixed block 3 can reset the rotating block 4. After feeding is completed, the bending mechanism 101 is driven downwards to cooperate with the V-groove 6 to bend the sheet. After pressing down, the pushing... The spring 9 inside the groove 7 can push the pusher 8, which was pressed down during bending, back out, thereby separating the bent sheet from the V-groove 6. After separation, as the conveyor 2 continues to rotate, the pressure plate 10 on it can collide with the pressure plate 11 on the frame 1 and push the pressure plate 11 to slide, so that the sliding pressure plate 11 can squeeze the airbag 12, so that the airbag 12 can blow the sheet that was bounced up by the pusher 8 and blow it out of the V-groove 6. Preferably, the fixing block 3 and the pressure plate 10 can be symmetrically arranged on the conveyor 2. When the pressure plate 11 no longer exerts pressure on the airbag 12, the airbag 12 can drive the pressure plate 11 to reset, or a spring can be added to push the pressure plate 11 to reset it.
[0022] In some embodiments, to further facilitate the airbag 12 to blow out the bent sheet metal, the depth of the ejection groove 7 increases with the distance from the output end of the airbag 12. Thus, after the sheet metal is ejected by the pusher 8, it is in an inclined state, and the airbag 12 can blow the inclined surface of the sheet metal to knock it off.
[0023] In some embodiments, to further facilitate the blowing off of the bent sheet, the number of airbags 12 may be increased as the weight of the sheet increases.
[0024] In some embodiments, an output receiving platform 13 is installed on the frame 1 to facilitate the collection of the blown sheet.
[0025] In some embodiments, in order to facilitate the airbag 12 to be compressed and then expelled, a vent pipe 14 is fixedly installed on the frame 1. The input end of the vent pipe 14 is connected to the airbag 12, and the output end of the vent pipe 14 is located on one side of the V-groove 6.
[0026] In some embodiments, to facilitate the pushing of pressure plate 10 onto pressure plate 21, both pressure plate 10 and pressure plate 211 are provided with chamfers, and a plurality of universal balls 15 are rotatably mounted on pressure plate 10. Pressure plate 10 is driven to rotate by conveyor 2. When it rotates to pressure plate 21, the chamfered portions of pressure plate 10 and pressure plate 21 press against each other, thereby pushing pressure plate 21 as pressure plate 10 continues to be driven, while the universal balls 15 reduce the friction between the two.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
