Description
Technical Field
[0001] The utility model relates to the technical field of bending machines, and particularly relates to a double-station loading and unloading workbench for a bending machine. Background Technique
[0002] A bending machine is an important device for bending and forming workpieces in the sheet metal industry. During the production process of aluminum single plates, when bending the edges of aluminum plates, the commonly used device is a bending machine. At present, during the use of a bending machine, it is usually necessary to use a robotic arm to send the aluminum plate to the bending position for bending, and then take it down and place it properly after bending. However, after the robotic arm loads the material, it needs to wait for the bending machine to bend the sheet before taking it down. Therefore, the idle time when the bending machine waits for loading or unloading is relatively wasted, resulting in low working efficiency of the bending machine and inconvenience for popularization and use. Therefore, we introduce a double-station loading and unloading workbench for a bending machine. Content of the Utility Model

[0030] A double-station loading and unloading workbench for a bending machine, comprising a bending machine body 1 and a bearing plate 2. The positions of the bending machine body 1 and the bearing plate 2 correspond to each other front and back. Support columns 3 are provided at the left and right parts of the front end and the left and right parts of the rear end of the bearing plate 2. Support plates 4 are fixedly installed at the lower ends of the two support columns 3 on the left and the two support columns 3 on the right. Two universal wheels 5 are provided at the lower ends of the two support plates 4. Placement tables 6 are provided at the upper ends of the two support plates 4. Moving grooves 7 are provided at the left and right parts of the lower end of the bearing plate 2. First motors 8 are provided at the left and right ends of the bearing plate 2. First threaded rods 9 are fixedly installed at the output ends of the two first motors 8. Guide rods 10 are provided inside the two moving grooves 7. Moving blocks 11 are jointly provided on the outer surfaces of the first threaded rods 9 and the guide rods 10 on the left and right parts. Fixing covers 12 are provided at the lower ends of the two moving blocks 11. Adjusting mechanisms 13 are provided on the inner surfaces of the two fixing covers 12. Fixing devices 14 are provided inside the two adjusting mechanisms 13.
[0031] In this embodiment, the adjusting mechanism 13 includes an electric slide rail 130. An electric slider 131 is arranged on the outer surface of the electric slide rail 130. A fixed frame 132 is fixedly installed at the lower end of the electric slider 131. A second motor 133 is fixedly installed on the inner lower wall of the fixed frame 132. A second threaded rod 134 is fixedly installed at the output end of the second motor 133. A U-shaped frame 135 is fixedly installed on the outer surface of the second threaded rod 134 through a driving block. A fixing plate 136 is fixedly installed at the lower end of the U-shaped frame 135. An installation plate 137 is fixedly installed on the inner front wall of the U-shaped frame 135; the fixing plate 136 is movably installed on the outer surface of the second threaded rod 134 through the U-shaped frame 135 and the driving block; the fixed frame 132 is slidably installed on the outer surface of the electric slide rail 130 through the electric slider 131; the fixed cover 12 is movably installed on the outer surfaces of the first threaded rod 9 and the guide rod 10 through the movable block 11.
[0032] Through the above scheme: The electric slide rail 130 in the adjusting mechanism 13 is started, and the electric slider 131 on its outer surface can move along the electric slide rail 130. Therefore, the movement of the electric slider 131 will drive the entire fixed frame 132 to move horizontally. The second motor 133 on the inner lower wall of the fixed frame 132 is started to drive the second threaded rod 134 to rotate. The U-shaped frame 135 fixedly installed through the driving block will move up and down with the rotation of the second threaded rod 134. The U-shaped frame 135 fixedly installed through the driving block will move up and down with the rotation of the threaded rod, which is convenient to adjust the position of the fixing plate 136 according to the actual situation and facilitate the subsequent picking and placing of workpieces.
[0033] In this embodiment, the fixing device 14 includes a vacuum pump 140. An output pipe 141 is arranged at the output end of the vacuum pump 140. A communicating pipe 142 is arranged at the lower end of the output pipe 141. Four cross pipes 143 are fixedly installed through the outer surface of the communicating pipe 142. Three air vent pipes 144 are arranged at the lower parts of the outer surfaces of the four cross pipes 143. Suction cups 145 are arranged at the lower ends of the twelve air vent pipes 144. A control valve 146 is arranged at the upper part of the outer surface of the output pipe 141; the suction cups 145 are interconnected with the vacuum pump 140 through the output pipe 141, the communicating pipe 142, the cross pipes 143 and the air vent pipes 144. The vacuum pump 140 is fixedly installed at the upper end of the installation plate 137.
[0034] Through the above solution: When the vacuum pump 140 is started, the vacuum pump 140 generates negative pressure, and the negative pressure is transmitted through the output pipe 141 at the output end. The negative pressure in the output pipe 141 is then transmitted to the connecting pipe 142 at the lower end. The connecting pipe 142 distributes the negative pressure to the four horizontal pipes 143 fixedly installed on its outer surface in an interspersed manner. The four horizontal pipes 143 then transmit the negative pressure to the three air vent pipes 144 provided at the lower part of their respective outer surfaces. Since suction cups 145 are provided at the lower ends of the twelve air vent pipes 144, the negative pressure is finally transmitted to the suction cups 145, causing negative pressure to be generated inside the suction cups 145, enabling the suction cups 145 to adsorb the plates, facilitating loading and unloading.
[0035] It should be noted that the present utility model is a double-station loading and unloading workbench for a bending machine. During use, first stack the aluminum plates to be bent on the placing table 6 on the left, and make the left fixing plate 136 located above the left placing table 6. Turn on the second motor 133 through the controller. The second motor 133 drives the second threaded rod 134 to rotate, thereby driving the U-shaped frame 135 to move up and down. When the U-shaped frame 135 moves downward to a suitable position and the twelve suction cups 145 below come into contact with the plates above the placing table 6, start the vacuum pump 140. The vacuum pump 140 generates negative pressure, which is sequentially transmitted to the connecting pipe 142, the four horizontal pipes 143, the twelve air vent pipes 144, and the twelve suction cups 145 through the output pipe 141. Negative pressure is generated inside the twelve suction cups 145, enabling the twelve suction cups 145 to adsorb the plates, facilitating loading. Turn on the first motor 8 on the left through the controller. The first motor 8 drives the first threaded rod 9 to rotate, thereby facilitating the movement of the components below the movable block 11 to the rightmost side. Turn on the electric slide rail 130 and the electric slider 131 through the controller, thereby facilitating the movement of the plates adsorbed by the twelve suction cups 145 to the bending machine body 1 for bending. Move the left fixing plate 136 to the leftmost side again through the controller to adsorb the plates. At the same time, the right fixing plate 136 moves to above the bent plates through the cooperation of the electric slide rail 130 and the electric slider 131. Through the cooperation of the vacuum pump 140 and each component, it is convenient to adsorb the plates. Then, through the cooperation of the first motor 8, the second motor 133, the electric slide rail 130, and the electric slider 131, it is convenient to move the bent plates to the placing table 6 on the rightmost side and place them properly for subsequent use, thereby reducing the idle time of the bending machine body 1 due to waiting for loading or unloading and improving the working efficiency of the bending machine body 1.
