INSTALLATION FOR CONTINUOUS MANUFACTURE OF LONG-SIZED PROFILE WORKPIECES OF COMPOSITE MATERIALS Russian patent published in 2002 - IPC

FIELD: equipment for processing of composite materials, in particular, for manufacture of long-sized profile workpieces, applicable in chemical, electrical engineering and other branches of industry and construction. SUBSTANCE: installation has successively installed bobbin holder with bobbins of longitudinal material and guide members, means for preliminary moulding of the workpiece of longitudinal material, bobbins of band material with guide members, means for preliminary profiling of band material, moulding die and a drawer. The moulding die has inner longitudinal bulges and a moulder of the inner channel of the profile workpiece. The guide member of band material is made in the form of a box-like profile of thin-walled plate material coaxially located at the outlet with the profile of the moulding die. The box-like profile is made with a longitudinal cavity, external working surface and at least one inner longitudinal corrugation with a guide groove. The means for preliminary moulding of the workpiece of longitudinal material is positioned in the longitudinal cavity of the box-like profile. The above means is made at least with two longitudinal channels for feed of band material through them, and channels for feed of longitudinal material to its walls. The moulder of the inner channel of the profile workpiece is made in the form of longitudinal members located in the longitudinal channel of the moulding die parallel to its inner longitudinal bulge. The means for preliminary profiling of band material is made in the form of a core-type guide member installed in the groove of the box-profile longitudinal corrugation. EFFECT: enhanced strength and reliability of workpieces, reduced consumption of materials. 10 cl, 21 dwg
