Description

Technical Field

[0001] This utility model relates to the field of metal sheet technology, specifically to a bending device. Background Technology

[0002] In the production and processing of metal sheets, due to the specific requirements of the products, it is often necessary to bend the metal sheets at a certain angle. This requires the use of appropriate bending devices. Usually, the thin sheet to be bent is placed on the workbench, and the bending pressure plate moves downwards, working in conjunction with the bending groove to bend the thin sheet.

[0003] For example, the national authorized patent announcement number CN220092621U discloses a bending device for metal sheets, including a lower die base. An auxiliary plate is fixedly installed on the top of the front of the lower die base. A fixing block is fixedly installed in the middle of the top of the auxiliary plate on the side away from the lower die base. A threaded rod is threaded in the middle of the fixing block. A knob is fixedly connected to one end of the threaded rod. This utility model of a bending device for metal sheets, by rotating the knob, drives the threaded rod to rotate, which drives the positioning rod to move back and forth, which drives the pointer to move back and forth until the value of the scale line pointed to by the pointer is equal to the distance between the bending point of the metal sheet and one side of the metal sheet. At this time, the distance between the positioning rod and the center of the bending groove is equal to the distance between the bending point of the metal sheet and one side of the metal sheet. When the corresponding side of the metal sheet is pressed against the positioning rod, the bending point of the metal sheet is located directly below the bending block, thereby achieving precise positioning of the bending point of the metal sheet.

[0004] However, although the bending device mentioned above has solved the corresponding problems, it cannot meet the needs of multi-angle bending in actual use, and it relies too much on manual adjustment, and the positioning efficiency is also poor. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a bending device.

[0006] The specific technical solution is as follows:

[0007] A bending device includes: a processing table, with fixed frames installed on both sides of the surface of the processing table, a bending block disposed within the fixed frames, a bending groove disposed at one end of the upper surface of the processing table, the bending groove being correspondingly disposed with the bending block, a through hole disposed at the center of the upper surface of the processing table, an auxiliary component disposed within the through hole, and hollow holes disposed at both ends of the surface of the processing table, each hollow hole containing a plurality of movable wheels rotatably mounted therein, the movable wheels being evenly distributed in length, a hydraulic cylinder disposed at one end of the lower surface of the inner wall of the fixed frames, the extension end of the hydraulic cylinder being connected to one end of the upper surface of the bending block, and guide rods fixedly connected to both ends of the upper surface of the bending block, the other end of the guide rods being inserted through one end of the upper surface of the fixed frames.

[0008] As a preferred embodiment of this utility model, a connecting frame is fixedly installed at one end of the fixed frame, a rotary motor is provided on one side of the connecting frame, a sliding groove is provided at one end of the lower surface of the inner wall of the connecting frame, a sliding block is slidably installed in the sliding groove, a threaded hole is provided at one end of the sliding block, a lead screw is threadedly connected in the threaded hole, and the output shaft of the rotary motor is connected to one end of the lead screw.

[0010] As a preferred embodiment of this utility model, the auxiliary component includes a linear cylinder, which is located at the lower end of a through hole provided in the center of the processing table. The extended end of the linear cylinder is connected to a connecting plate, and a rotating shaft is rotatably mounted on the upper surface of the connecting plate. A connecting rod is rotatably connected to the upper surface of the rotating shaft.

[0011] As a preferred embodiment of this utility model, a bearing plate is fixedly connected to the upper surface of the connecting rod, the bearing plate is located in a through hole provided in the center of the processing table, and a rotating gear is installed around the lower half segment of the connecting rod.

[0012] As a preferred embodiment of this utility model, a drive motor is provided at one end of the lower surface of the connecting plate, and the output shaft of the drive motor is connected to a transmission gear, which meshes with a rotating gear.

[0013] This utility model has the following beneficial effects:

[0014] 1. The bending device provided by this utility model, through the design of hydraulic cylinder, bending block, lower pressure plate, and auxiliary components, places the metal sheet to be bent on the processing table. The position of the metal sheet can be adjusted by the moving wheels to accurately place it in the appropriate position. After placement, the rotary motor drives the lead screw to drive the sliding block to move the electric push rod to the upper end of the metal sheet. The piston rod of the electric push rod drives the lower pressure plate to descend. The contact blocks installed at the four corners of the lower pressure plate contact the surface of the metal sheet. Then, the sliding block can be moved to move the lower pressure plate to the upper end of the bending groove. The hydraulic cylinder pushes the bending block down, and the sheet bends along the bending groove. The guide rod ensures the stability of the bending block's movement trajectory. The bending direction of the sheet can be changed by the auxiliary components, enabling multi-angle bending, improving adaptability, reducing manual labor, improving processing efficiency, and accelerating positioning efficiency.

[0015] 2. The bending device provided by this utility model, through the design of a linear cylinder, connecting plate, rotating shaft, and bearing plate, allows the linear cylinder to extend and drive the bearing plate to rise when the metal sheet needs to be bent at another angle. The retraction of the electric push rod causes the linear cylinder to extend and drive the bearing plate to rise. The metal sheet placed on the processing table then rises together with the bearing plate, contacting the surface of the lower pressure plate. The drive motor is then activated, driving the transmission gear to drive the rotating gear, which in turn drives the connecting rod to rotate. The rotating shaft, connected to the lower surface of the connecting rod, rotates, causing the connecting rod to drive the bearing plate to rotate as well. Because the rotating shaft is rotatably installed at the connection between the electric push rod and the lower pressure plate, the lower pressure plate can rotate accordingly, allowing the metal sheet to be bent at different angles. This adapts to multi-angle bending needs, eliminates the need for frequent manual adjustments, improves usability, and speeds up bending efficiency. Attached Figure Description

[0030] Example 1

[0031] The bending device provided in this embodiment, such as Figures 1-5As shown, it includes: a processing table 1, with fixed frames 2 installed on both sides of the surface of the processing table 1, and bending blocks 203 provided inside the fixed frames 2. A bending groove 204 is provided at one end of the upper surface of the processing table 1, and the bending groove 204 is correspondingly provided with the bending block 203. A through hole is provided at the center of the upper surface of the processing table 1, and an auxiliary component 4 is provided in the through hole. Holes are provided at both ends of the surface of the processing table 1, and multiple moving wheels 101 are rotatably installed in each of the holes. The moving wheels 101 are evenly distributed in length. A hydraulic cylinder 201 is provided at one end of the lower surface of the inner wall of the fixed frame 2. The extension end of the hydraulic cylinder 201 is connected to one end of the upper surface of the bending block 203. Guide rods 202 are fixedly connected to both ends of the upper surface of the bending block 203, and the other end of the guide rods 202 is inserted through one end of the upper surface of the fixed frame 2. A connecting frame 3 is fixedly installed at one end of a fixed frame 2. A rotary motor 301 is provided on one side of the connecting frame 3. A sliding groove 302 is provided at one end of the lower surface of the inner wall of the connecting frame 3. A sliding block 304 is slidably installed in the sliding groove 302. A threaded hole is provided at one end of the sliding block 304. A lead screw 303 is threaded into the threaded hole. The output shaft of the rotary motor 301 is connected to one end of the lead screw 303. An electric push rod 305 is installed at one end of the lower surface of the sliding block 304. The piston rod of the electric push rod 305 is connected to a lower pressure plate 306. A rotating shaft 308 is rotatably installed at the connection between the lower pressure plate 306 and the piston rod. Multiple pressing blocks 307 are fixedly installed on the lower surface of the lower pressure plate 306, and the multiple pressing blocks 307 are distributed in a rectangular shape at the four corners.

[0032] Through the design of hydraulic cylinder 201, bending block 203, lower pressure plate 306, and auxiliary component 4, the metal sheet to be bent is placed on the processing table 1. The position of the metal sheet can be adjusted by the moving wheel 101 to ensure it is accurately placed in the appropriate position. After placement, the rotary motor 301 drives the lead screw 303 to drive the sliding block 304, which in turn drives the electric push rod 305 to move to the upper end of the metal sheet. The piston rod of the electric push rod 305 drives the lower pressure plate 306 to descend. The contact blocks 307 installed at the four corners of the lower surface of the lower pressure plate 306 contact the surface of the metal sheet. Then, the sliding block 304 can be moved to move the lower pressure plate 306 to the upper end of the bending groove 204. The hydraulic cylinder 201 pushes the bending block 203 down, and the sheet is bent along the bending groove 204. The guide rod 202 ensures the stability of the movement trajectory of the bending block 203. The bending direction of the sheet can be changed by the auxiliary component 4, enabling multi-angle bending, improving adaptability, reducing manual labor, improving processing efficiency, and accelerating positioning efficiency.

[0033] Example 2

[0034] The bending device provided in this embodiment, such as Figures 2-5As shown, the auxiliary component 4 includes a linear cylinder 401 located at the lower end of a through hole at the center of the machining table 1. A connecting plate 403 is connected to the extended end of the linear cylinder 401. A rotating shaft 404 is rotatably mounted on the upper surface of the connecting plate 403, and a connecting rod 405 is rotatably connected to the upper surface of the rotating shaft 404. A bearing plate 402 is fixedly connected to the upper surface of the connecting rod 405, located within the through hole at the center of the machining table 1. A rotating gear 406 is mounted around the lower half of the connecting rod 405. A drive motor 408 is located at one end of the lower surface of the connecting plate 403. A transmission gear 407 is connected to the output shaft of the drive motor 408, and the transmission gear 407 meshes with the rotating gear 406.

[0035] Through the design of linear cylinder 401, connecting plate 403, rotating shaft 404, and bearing plate 402, when the metal sheet needs to be bent at another angle, the electric push rod 305 retracts, causing the linear cylinder 401 to extend and drive the bearing plate 402 to rise. Then, the metal sheet placed on the processing table 1 rises together with the bearing plate 402, so that the metal sheet contacts the surface of the lower pressure plate 306. The drive motor 408 is started, which drives the transmission gear 407 to drive the rotating gear 406, which drives the connecting rod 405 to rotate. The rotating shaft 404, which is rotatably connected to the lower surface of the connecting rod 405, rotates, causing the connecting rod 405 to drive the bearing plate 402 to rotate together. Since the rotating shaft 308 is rotatably installed at the connection between the electric push rod 305 and the lower pressure plate 306, the lower pressure plate 306 can rotate accordingly, allowing the metal sheet to be bent at different angles. This can adapt to the needs of multi-angle bending, eliminate the need for frequent manual adjustments, improve practicality, and speed up bending efficiency.

[0036] In summary, the bending device provided in this embodiment has the following advantages: it can adapt to the bending angle requirements during use without relying on manual adjustment, thus improving adaptability; and it can quickly position itself during use, thereby improving positioning efficiency and accelerating the bending process.

[0037] In use, the sheet metal is placed on the processing table 1, and its position is adjusted by sliding the movable wheels 101 on the surface of the processing table 1 to quickly align with the bending groove 204, reducing manual handling and rough adjustment time. Then, the rotary motor 301 drives the lead screw 303, which moves the sliding block 304 laterally above the sheet metal. The electric push rod 305 connected to the lower surface of the sliding block 304 moves together to achieve precise pre-positioning of the pressing position. The electric push rod 305 pushes the lower pressure plate 306 down, and the four corner contact blocks 307 simultaneously contact the surface of the sheet metal to ensure uniform distribution of the pressing force and prevent the sheet metal from shifting or warping. Then, the hydraulic cylinder 201 pushes the bending block 204. 3. Press down, the sheet metal is bent and formed along the bending groove 204. The guide rod 202 ensures the stability of the movement trajectory of the bending block 203. The electric push rod 305 retracts to release the sheet metal. The linear cylinder 401 pushes the bearing plate 402 to rise, lifting the sheet metal off the surface of the processing table 1. The drive motor 408 drives the connecting rod 405 through the transmission gear 407 and the rotating gear 406, causing the bearing plate 402 to rotate. The pressure plate 306 adjusts the direction of the sheet metal and adapts to the rotation angle through the rotating shaft 308. The sheet metal can be pressed again without disassembly. The bearing plate 402 descends and resets. The hydraulic cylinder 201 drives the bending block 203 again to complete the bending at a new angle.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
