APPARATUS FOR ASSEMBLING SPRING BLOCK, UNIT FOR FORMING BRACKET AND UNIT FOR FEEDING ELONGATED MATERIAL TO IT Russian patent published in 2006 - IPC B21F33/04 B21D11/10 B21D53/36 B21F45/16 B21D43/11 

FIELD: apparatuses for combining springs to blocks, possibly in furniture making or automobile making industry branches for making mattresses, sofa and chair seat cushions.

SUBSTANCE: apparatus for assembling spring block includes arranged successively according to order of manufacturing process: unit for feeding elongated material for forming bracket; unit for forming bracket with mechanism for cutting off elongated material; unit for joining peripheral springs to carcass of framework. Unit for forming bracket includes built-up plate assembled of two parts with equidistant mutually opposite surfaces. Between said surfaces there is gap that is no less than thickness of bracket material. Said surfaces are rounded to side of working zone for forming bracket. Unit for feeding elongated material for forming bracket includes leverage reciprocation-motion mechanism in the form of slide; drive device and lever. The last is mounted by its one end with use of rotation axle onto slide and its one arm is joined with rod of drive device. Invention provides improved strength and increased useful life period of spring block.

EFFECT: simplified design, enhanced operational reliability of apparatus for assembling spring block of improved strength.
