For all those who are concerned about the quality and cost of mass-produced parts for automobiles, robots, precision equipment, etc.
This is a case in which the issue was to change the gear manufacturing method and integrate the parts.
At the development stage, a two-part assembly of a shaft and gear (sintered product) was considered, but we were consulted to see if there was a way to further reduce costs.
To address specific issues, we have achieved a reduction in the press-in process and cost by integrating molding with an 8-stage parts former.
The product originally consisted of two parts. The gear was formed by a powder press, and the pin made of SUS was finished by cutting with an automatic machine, and then the pin was inserted and assembled to the gear using a press-fit machine.
The key point of our proposal this time was to reduce the number of processes.
As a result, the three processes (sintering, cutting, and assembly (press fitting)) were reduced to one process, resulting in the following three merits.
(1) Cost reduction by reducing man-hours
(2) Increased strength through integration
(3) Increased hardness due to cold forge hardening of the gear section
Although the final product was not mass-produced, the customer appreciated the high quality of the technology.
A client consulted us regarding a change in gear construction method. This is a proposal for a VE case involving drawing changes, which is one of our specialties.
