[Introduction to Sheet Metal Processing Technology] A method for positioning half punches without exposing them on the surface.

basic information

The front of machines and equipment often has strong aesthetic elements, and there are many cases where spot marks and unevenness on the surface are undesirable. For example, in the case of a cabinet door, it is common to spot weld reinforcement plates on the back, and the positioning of these plates often employs the "half punch" method. This method offers advantages such as greater dimensional accuracy compared to methods using punches (marking) or jigs, and it is less affected by the skill level of the workers. However, a disadvantage of using a standard half punch is that it can create dents on the surface. If left as is, it cannot meet the aesthetic requirements for the finished surface, so methods such as filling the welds to create a uniform surface or using putty treatment to achieve uniformity are employed to finish the appearance. Naturally, this increases manufacturing costs, which becomes a significant drawback.

Applications/Examples of results

The mold we use, known as the "FP mold," retains the advantages of half punches as positioning tools while eliminating the disadvantage of surface dents, allowing for the molding of half punches without these issues. While there may be some minor draw marks on the surface, they can be leveled out with minimal effort, and this can be managed with a slight increase in cost. Additionally, it prevents human error during welding or when filling with putty. However, it is not suitable for processing materials like SUS or aluminum, or for both sides of a surface, and is specifically used for certain items like iron decorative covers. Our goal is to combine optimal processing methods that cater to customer needs, whether they prioritize aesthetic appearance or not, and to propose a system in the design and CAM processes that meets both cost and quality requirements.
