Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal bending device with adjustable curvature. Background Art

[0002] With the rapid development of mechanical processing industry, my country's processing machinery is becoming more and more developed. A bending device for metal materials has appeared in the processing machinery. The bending device mainly realizes the processing of the shape of the object by changing the physical state of the formed material. It is used to make the blank into a part with a specific shape and size under the pressure of the bending machine.

[0003] According to the search, Chinese patent literature, announcement number: CN218424923U, discloses a sheet metal bending device with adjustable curvature, which starts the motor to rotate the transmission rod, and the transmission rod rotates the secondary chain wheel through the belt, and the secondary chain wheel rotates the lead screw. Due to the rotation of the lead screw, the slider slides along the front end of the bracket, thereby moving the slider, the slider moves the sliding sleeve, and the sliding sleeve moves the sliding column. When the sheet metal is placed on the placement plate, the roller can press against the surface of the sheet metal, so that other parts of the sheet metal surface can be bent normally and move toward the middle, avoiding damage to the sheet metal due to excessive pressure. When the curvature needs to be changed, the hydraulic rod is started to rotate the placement plate around the shaft rod, and the shaft rod rotates on the bracket and the fixed plate. By adjusting the angle, the inclination of the placement plate can be adjusted, thereby realizing the adjustment of the curvature of the sheet metal. However, during use, the top side of the sheet metal is limited by rollers. Although the limiting effect can be achieved, when bending is performed and the cylinder is started to adjust the rotation angle of the placement plate, the sheet metal is easily offset to the left and right under the reverse action, which can easily cause the bending position to change, thereby reducing the bending accuracy.
