Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal chassis multi-point bending machine. Background Art

[0002] Sheet metal chassis bending is an indispensable processing method in the production of sheet metal chassis. At present, the common sheet metal chassis bending methods mainly include manual bending and bending by bending machine. Since manual bending is time-consuming and labor-intensive, bending by bending machine is more desirable.

[0003] However, traditional bending machines can usually only install the upper mold or the lower mold, and cannot install them at the same time. This requires additional positioning work when assembling the mold, which increases the preparation and replacement time of the mold and increases production costs. In addition, the upper mold will generate a lot of heat due to frequent contact and friction with the plate during operation. However, most existing bending machines do not have effective cooling measures. Excessive heat in the upper mold will not only affect its service life, but may also cause mold deformation, further affecting the bending accuracy.

[0004] Therefore, it is necessary to provide a sheet metal chassis multi-point bending machine to solve the above technical problems. Utility Model Content
