TOOLING BATCHED EQUIPMENT Russian patent published in 2009 - IPC B21D22/00 B21D51/00 B21D41/04 

FIELD: mechanics.

SUBSTANCE: group of inventions relates to metal treatment by pressure, particularly to manufacture of double-part bodies of metal container. Module-type matrix includes circular body with inner and outer surrounding walls. The body is provided with die fixing elements, multiple molded cavities in the above mentioned inner surrounding wall. The moulded cavities are distributed along wall circle. Each cavity is provided with internal and external section, tensile damping element located on the said external section of each molded cavity. There is also hard contact element located on the above-mentioned internal section of each moulded cavity. The said contact element has trapezoidal shape, provided with a multiple set of friction surfaces, contacts with the said hard element and extends to the external direction of the above mentioned inner surrounding surface. The tooling batched equipment contains holder and die bearing element for the secondary extraction, at least one modular matrix having circular housing and a multiple set of damping elements for die self-centering with regard to the cyclic die. So the above-mentioned damping element includes hard contact element with a multiple set of surfaces and at least one separating element. The tooling batched equipment is designed to manufacture container body in multiple cycle process. It is comprised of a modular matrix having circular body with inner and outer surrounding walls and die fixing unit. At least one friction plate is located on the said outer surrounding wall of the matrix. A multiple number of molded cavities are available on the same outer surrounding wall and distributed along its circle. Each cavity is provided with internal and external sections, fixing section, elastic damping element located on the said external section of each moulded cavity. The above mentioned elastic element is provided with fixing element contacting with the said fixing section of the cavity. The hard contact element is located on the said internal section of each moulded cavity and provided with multiple friction surfaces. It contacts with the said elastic damping element and extends in the external direction from the said inner surrounding wall.

EFFECT: wide engineering capabilities and improved quality of items.
