Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumper grinding, in particular to an automobile bumper blank grinding device. Background Art

[0002] The bumper on the car is basically a curved plastic shell, which has a certain function of absorbing and mitigating external impact and protecting the car body and occupants. When the car bumper is separated from the mold, there will be burrs and uneven surfaces. The burrs and uneven surfaces need to be trimmed before the painting operation. However, it is too expensive to improve the mold body to solve the burrs and uneven surfaces caused by the demoulding of the car bumper. In addition, there are many types and sizes of car bumpers, and the mold volume is large, which undoubtedly increases the cost of improving the mold. Therefore, the bumper needs to be polished to remove burrs and trim the surface, and the paint adhesion of the bumper surface after polishing is better.
