Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a multifunctional composite sheet metal bending auxiliary tool. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Its significant characteristic is that the thickness of the same part is uniform. Products processed through sheet metal processing are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly. In sheet metal processing, bending is usually done by a bending machine. Currently, bending sheet metal parts typically requires manual lifting or support. After prolonged periods of repetitive bending, workers are prone to fatigue, potentially leading to accidents due to fatigue or operational errors. Therefore, we propose a multi-functional composite sheet metal bending auxiliary tool. Utility Model Content

[0021] Example 1

[0022] Please see Figures 1-5As shown, this embodiment provides a multifunctional composite sheet metal bending auxiliary tool, including a bending die 1. A U-shaped connecting block 6 is slidably disposed on the outer side of the bending die 1. Side grooves 4 are formed on both sides of the bending die 1, and rollers 5 are rotatably disposed inside the side grooves 4. The rollers 5 are rotatably mounted inside the U-shaped connecting block 6. When the U-shaped connecting block 6 slides, the rolling of the rollers 5 inside the side grooves 4 guides and limits the sliding of the U-shaped connecting block 6. At the same time, the rolling of the rollers 5 reduces the friction between the bending die 1 and the U-shaped connecting block 6, thus protecting the device. A first adjusting device 2 is provided on one side of the U-shaped connecting block 6. The first adjusting device 2 includes a first connecting block 21. An inner groove 22 is formed inside the first connecting block 21. A screw 26 is rotatably disposed inside the inner groove 22. The end of the screw 26 away from the bending die 1 passes through the first connecting block 21 and extends outward. A screw sleeve 23 is threadedly connected to the outer side of the screw 26 and is slidably disposed inside the inner groove 22. A push plate 24 is slidably mounted on the upper side of the first connecting block 21. L-shaped connecting rods 25 are fixedly connected to both sides of the push plate 24. The horizontal end of the L-shaped connecting rod 25 passes through the first connecting block 21 and is fixedly connected to the screw sleeve 23. When the position of the sheet metal part needs to be adjusted, the screw 26 is rotated to make the screw sleeve 23 slide inside the inner groove 22, thereby driving the push plate 24 to slide on the upper side of the first connecting block 21 and pushing the sheet metal part to move closer to the bending die 1, thus adjusting the position of the sheet metal part. Guide grooves 27 are provided on both the upper and lower sides of the inner groove 22. A guide block 28 is slidably mounted inside the guide groove 27. The guide block 28 is fixedly mounted on the screw sleeve 23. When the screw 26 rotates, the sliding of the guide block 28 inside the guide groove 27 guides the sliding of the screw sleeve 23, preventing the screw sleeve 23 from being affected by the rotation of the screw 26 during sliding, thus avoiding excessive scraping of the screw sleeve 23 against the first connecting block 21 and extending the service life of the device.

[0023] A second adjusting device 3 is provided on the other side of the U-shaped connecting block 6. The second adjusting device 3 includes a second connecting block 31. A fixing plate 32 is fixedly connected to the upper side of the second connecting block 31. An extrusion plate 33 is slidably disposed on the upper side of the second connecting block 31 between the fixing plate 32 and the bending die 1. A first connecting rod 34 is fixedly connected to the side of the fixing plate 32 near the bending die 1. A second connecting rod 35 is slidably disposed inside the first connecting rod 34. One end of the second connecting rod 35 passes through the first connecting rod 34 and extends outward to be fixedly connected to the extrusion plate 33. A spring 36 located inside the first connecting rod 34 is fixedly connected to the end of the second connecting rod 35 away from the extrusion plate 33. When When the push plate 24 pushes the sheet metal part to move, the sheet metal part will come into contact with the surface of the extrusion plate 33 as it moves. The elastic thrust applied to the second connecting rod 35 by the spring 36 makes the extrusion plate 33 support the sheet metal part. When the sheet metal part is moved to the appropriate position, the two ends of the sheet metal part are subjected to opposing thrusts, thereby fixing the sheet metal part. The first connecting rod 34 has a limit groove 37 inside, and a limit block 38 is slidably arranged inside the limit groove 37. The limit block 38 is fixedly installed on the second connecting rod 35. The position of the second connecting rod 35 is limited by the sliding of the limit block 38 inside the limit groove 37, so as to prevent the second connecting rod 35 from slipping and causing device failure.

[0024] A multi-stage telescopic rod 39 located on both sides of the first connecting rod 34 is fixedly connected between the fixed plate 32 and the extrusion plate 33. When the extrusion plate 33 slides on the upper side of the second connecting block 31, the multi-stage telescopic rod 39 keeps the extrusion plate 33 balanced, preventing it from getting stuck due to uneven force. At the same time, a groove 311 is provided on the upper surface of the second connecting block 31, and a slider 322 is slidably arranged inside the groove 311. The slider 322 is fixedly installed on the lower side of the extrusion plate 33. When the extrusion plate 33 slides, the slider 322 guides the sliding of the extrusion plate 33 by sliding inside the groove 311, and keeps the extrusion plate 33 in contact with the second connecting block 31, preventing the extrusion plate 33 from being lifted up during the movement of the sheet metal part, making the device more stable.

[0025] In this embodiment, a multifunctional composite sheet metal bending auxiliary tool is used by the user who first pushes the U-shaped connecting block 6 to move the first connecting block 21 and the second connecting block 31 to the appropriate position. Then, the sheet metal part is placed on the upper side of the first connecting block 21, and the spring 36 is rotated to make the screw sleeve 23 slide inside the inner groove 22. This causes the push plate 24 to push the sheet metal part towards the bending die 1. As the sheet metal part moves, it abuts against the extrusion plate 33, and the spring 36 acts on the second connecting rod. The elastic thrust applied by 35 causes the extrusion plate 33 to extrude the sheet metal part, thereby fixing the position of the sheet metal part. The sliding of the slider 322 inside the slide groove 311 guides and limits the sliding of the extrusion plate 33, so that the extrusion plate 33 always abuts against the second connecting block 31. At the same time, the multi-stage telescopic rod 39 keeps the extrusion plate 33 balanced, preventing the extrusion plate 33 from tilting due to uneven force. After the sheet metal part moves to the appropriate position, the bending device is opened to bend the sheet metal part.
