Customer's Request We want to significantly shorten the production lead time by utilizing painted steel sheets. We aim to streamline production by eliminating work-in-progress items and reducing costs. We desire a line that can produce necessary items when needed. Additionally, we want to prevent environmental pollution in the atmosphere and water quality and significantly improve the workplace environment. Reason for Choosing Enami Seiki Due to the small space that fits into a low-ceiling assembly factory (about 3m), a pit for pressing is not necessary. They have a wealth of experience in the pressing of painted steel sheets. Development Goals By adopting PCM steel sheets, we aim to establish a method of joining components using riveting as an alternative to welding, while also achieving a scratch-free processing (pressing) of the outer frame appearance. Additionally, we aim to realize a no-changeover production line by only exchanging molds for two models with different curvatures that have a fully rounded shape. Results (Customer Feedback) We were able to reduce manufacturing costs by 20% before and after using painted steel sheets.

The Enarock series is a general-purpose press machine fixture designed for joining two metal plates using a press machine. It enables fastener-less joining of metals without the use of welding, fastening materials, or adhesives, allowing for simultaneous joining during the pressing process by being integrated into the mold. It can achieve appropriate fastening regardless of whether the materials are the same or different, such as iron, stainless steel, or aluminum. Additionally, since it does not require heating, it can also be used with painted steel sheets. Furthermore, by utilizing plastic processing, it allows for high-speed processing, thereby increasing productivity. Enarock helps achieve further reductions in running costs. We pursue the minimization of production costs with a long-lasting design, offering the low-cost, reusable dive blade "Cutlock" that can be used four times, and the "Drawlock," which is ideal for products requiring airtightness, responding to low cost and short delivery times.

We changed the production of various types of box containers from the traditional lot production method to a mixed production method according to the order quantity, significantly reducing work-in-progress and finished goods inventory while automating production and greatly shortening product delivery times. We devised a setup-free production line for various types of box containers and an instantaneous switching method within the mold, achieving a mixed production system capable of producing from a minimum lot size of one unit.

We changed the production method of external cases from the conventional spot welding and painting of surface-treated steel sheets to a joining method using clinching that combines PCM steel sheets and zinc-coated steel sheets. This transition eliminates the traditional welding and painting processes, significantly reducing the number of steps and work in progress, while also achieving an environmentally friendly production method that has gained particular recognition recently. We aimed to develop a cost-effective production line by adopting the case-integrated clinching technology of the Drawlock, one of the Enarock series, through the multi-tool approach and man-machine integration, which are our areas of expertise.

We have achieved press processing that includes drawing of painted steel sheets without any scratches. The transfer between processes can be automated with a conveyor system, allowing for unmanned operation. The height of the press machine is low, allowing it to be installed directly in the assembly line. Previously, after press processing, painting was done and labels were applied, but now, by using painted steel sheets combined with printed labels, the parts can be completed in the press process. With a press machine height of 2400mm, it can be installed within the assembly line factory, enabling a streamlined process from pressing to assembly completion. It can be installed without a pit, and layout changes are also easy.

The device can simultaneously process the end flaring, hemming bending, and roll forming of cylinders. The flaring processing section uses a servo press machine. In the conventional method, which involves expanding a core for shaping, it was easy to create processing marks on the inner surface of the cylindrical part. However, our equipment does not produce any processing marks. The device that simultaneously performs end flaring, hemming bending, and roll forming of cylinders has significantly improved productivity. The flaring process increases the strength of the flared section and allows for the use of thinner materials. Specifications

It is possible to perform press processing on painted steel plates without damage. Double-action press Simultaneous forming of central deep drawing/drilling, outer peripheral step drawing (two stages), and outer peripheral trimming (hydraulic mechanism). Curling device Simultaneous curling of the tip of the drawing part and the outer shape (square) (servo mechanism). Previously, there were 8 processes, but now it can be processed in 2 processes. By reviewing the processing methods and parts, we were able to significantly compact the processing machine. Until now, molds were required for each model, necessitating a large space, but the shortened processes and space-saving of the processing machine have also reduced the required storage space.

High-speed processing is possible due to simultaneous riveting. Assembly is performed using a technology that joins different materials, such as painted steel sheets and Galvalume steel sheets, without using welding. The machine installation space is very small (2.3m × 1.2m). By adopting the riveting method, high-speed processing has become possible, eliminating the need for screws and rivets. By dividing the outer box into four parts, it is possible to change the material of the back and bottom surfaces.

Simultaneously with SR molding, the overlapping on the back side is processed by riveting. By maintaining the rivet, it prevents the corners from opening. By switching from conventional spot welding to riveting, the fastening strength has become stable. There was also an effect of improving the working environment due to the elimination of the welding process.
