COMPRESSION SPRING

At that time, it was necessary to assemble 32 springs in order to press 16 needles against the retainer with one-way clutch bearings for automobiles. However, the assembly takes a lot of man-hours. The customer was seeking to reduce the man-hours required for the work.

As an operation, since two compression springs of the same shape are assembled per needle, if this push spring is one part connected from the beginning, the assembly can be completed in one operation. Can this not be connected?

• Development Speed
• Advanced Technological Capabilities to Reduce the Number of Cutting-Edge Equipment Components

Since the machine setter which heard the explanation could not be processed at all by the conventional coiling machine, it was decided to change to the NC multi-forming machine. However, because of the structure of the machining machine, machining is not possible by a series of programs, but by devising such as preparing a sub-program halfway, it was possible to make two springs into a set. As a result, 32 assembly steps were reduced by half to 16 steps, and customer ordering management was also simplified. After 10 years of development, the line became the standard product with 24 hours full operation a month.
