Abstract: In the car body repair teaching activities or car body repair skills competitions in vocational colleges, the indentation with the same position and shape must be made safely and quickly on the door so that students or competitors can use it. The indentation machine designed in this paper can be used to specially manufacture the door indentation. Through the analysis of ANSYS, the main components of the indentation machine can meet the mechanical performance requirements that need to be met in work. Compared with the common indentation machine on the market, this new type of indentation machine has the advantages of simple structure, more convenient use, lower cost, easy control of indentation depth and position, and can make corresponding molds according to different indentation requirements, which is convenient for teaching and competition.
