Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile sheet metal bending and discloses an automobile sheet metal bending device. Background Art
[0002] Automotive sheet metal generally refers to the metal shell of the car, which is usually made of steel plates. On the basis of ensuring a certain strength, reducing the weight as much as possible is the basic requirement. In addition to protection and beautification, automotive sheet metal is also the main carrier for the car to withstand air resistance.
[0003] Before the automobile sheet metal is put into use, it needs to be bent according to demand, which requires the use of a bending device. The traditional bending device places the automobile sheet metal on the platform and fixes the automobile sheet metal by pressing down on the positioning parts to complete the bending work of the automobile sheet metal.
[0004] When this kind of bending work is in progress, since the positioning parts are fixed by downward pressure, in the actual processing process, the pressure generated during the bending work is relatively large. If only downward pressure is used, there is a hidden danger of instability, which may cause deviation during the bending work and affect the accuracy of the bending. Utility Model Content

[0008] Furthermore, at least two of the first mounting frames are provided, and linear motors are installed at both ends of the processing platform, and the first mounting frames are slidably arranged on the linear motors.
[0009] Furthermore, at least two first cylinders are installed on the first mounting frame, and telescopic ends of the first cylinders are connected to the positioning plate.
