Roller Hemming System
|
Hemming operation definition Hemming is a method of joining metal parts when welding or other similar methods are not possible. Typically, this process involves folding the overlapping flanges of the outer panel over the edges of the inner panel. Today, hemming is widely used in the automotive industry to assemble car closures such as doors, trunk lids and hoods. Of course, hemming has also become very common in areas such as rear fenders and sunroofs in recent years. Hemming operations generally involve following stages: 1. Flanging 2. Bonding 3. Marriage 4. Folding Unfortunately, since the first and second stages of hemming operations are usually performed in press shops, many engineers and experts consider the entire hemming operation to be only equal to the folding stage, while this stage is only the final stage of Hemming operation.

Today different Folding technologies are used in the automotive sector but the most important folding methods can be classified into three categories: Folding press, Table tops and Robotic Roller systems. These are distinguished by various factors such as investment level, process, time and technical requirements.
In recent years, due to the advantages of folding operations with the robotic roller hemming method, APQ company's technical and engineering focus has been on this method, and very good innovations have been created in the fields of design , engineering , construction and installation activities. Now it can be said that these efforts have made customers satisfied with the quality of project implementation.

Robotic Roller Systems
Robotic Roller System is a method which is not similar to other methods, is accompanied by a cylinder mechanism operating in a circular motion on the 6th axis of an industrial robot. Robotic roller in sheet metal folding application, cylinder mechanisms are used at different diameters according to process needs. These are called Robotic roller folding heads. Roller folding heads can be purchased as standard or specially designed according to process requirements. The geometric differences of required heads have an effect on the bending process. The heads should be designed and manufactured in the form of corner of the part to be fold, differently from the form of the twist, or supplied from suppliers on the market according to their suitability.
Robotic roller hemming is a relatively new method and there is very limited documentation and know-how about the process. Achieving and maintaining the right product quality is possible through a number of trial and error processes. Finite element analysis helps to shorten the trial and error process of the robotic roller hemming process. |

APQ and Roller Hemming systems
Since the construction of hardware equipment and software development in the field of roller hem systems is one of the most specialized activities defined in the strategies of this company, during the past years after the establishment of the company, our specialists made many efforts in various fields that have been associated with this activity.
Some of these research and developments are:
I. Material development (casting bed, rollers, blades, ...)
II. Preparing necessary engineering modules in standard softwares such as CATIA, DELMIA and AUTOFORM
III. Standardization of mostly used systems and mechanism
IV. Develop and apply quality control processes
