h lraises progressive stamping performance to new level.

The knuckle link slide motion and the ultra-highly rigid frame bed structure have changed
the concept of stamping processes and enabled high value added and high precision
production. Precision and roughness of surface have been improved and processing ofproducts having sharp and complicated shape have been enabled by utilizing, in addition
to punching, bending, drawing and burring, cold forging technologies of upsetting,extrusion and ironing, and a cutting method of shaving

Possibilities of press process expands.
So far, in case of metal processing for complicated shaped products, jointing, cutting or some other processing methods
must have been used to complete the products after processed in a stamping process. But, since the high precision knuckle link press enables metal processing for complicated three-dimensional shape with a single stamping press machine, youcan produce products that were impossible to process with one machine before (transfer robot compatible).
● Conventional methods(non-stamping process)1. Lost-wax casting
2. Sintering and MIM
3. Die-casting
4. Cutting
5. Welding

2● Change of process conversion to stamping
process with knuckle link press〈Processing of 3 dimension parts by stamping press〉
Complicated shape products without jointing andcutting steps can be processed by progressive
stamping combined with coining, restriking, shaving, ironing, etc.

Time required for highly accurate processing

・By decelerating at near bottom dead center and almost stopping at bottom deadcenter, accurate plastic process can be made and unconventional, high precision
working that doesn't accompany spring back can be realized.
・Slow return movement of a normal punch when returning from a die clears
obstacle in operation rate due to scrap rising accurately.

PDL series

Highly rigid frame bed structure
・This frame is several times more rigid than normal press, and small elongation when being pressurized with highly rigid structure of the column, slideand crown. The machine has an optimum frame bed structure.
・Overall elongation is 0.005 mm/10 kN or less.
・Difference in elongation of right and left of the frame due to eccentric load isvery small and maintaining of parallelism is stable.

・With combination of highly rigid frame bed structure and T-shaped bolster structure, high precision and high value added production of stamping process havebeen realized.
4High precision slide guide utilizing 4 post guides
・Adoption of four quenched and polished post guides assures the structure
superior in eccentric load resistant property.

・The load monitor detects overload and monitors left-to-right eccentric loads toprotect the press and provide consistent part quality.
・Anti-jamming function is adopted to enable lifting as it is even if stopped at bottom
dead center with load of 100%.

2 High value added and high precision progressive stamping process1

Solution to problem (improvement of product precision, stability of quality)
・Stable precision of products is realized by high precision press process.
・Strength of shape deformation can be improved with continuous layer of material (material flow line) and processing hardening. Also,
development of downsizing for products is available from stating parts design.

2

Process conversion (cost reduction and rationalization are achieved)
・Complicated shape process can be produced with only stamping process for using super accurate knuckle link press. Therefore, conventionally required cost for each process can be saved and also, production steps are reduced. As a result, rational production
processes are created.

3Improvement of working environment (creation of clear work environment)
・The working environment is kept clean as the front of slide is covered by a guard.
・Touching noise of the upper die and processing noise have been reduced by the highly rigid frame.
・The suction system of oil mist for cooling dies and other optional features assists the creation of clean environment.
