DEVICE FOR CONFIGURED PRESSING OF WOODEN PARTS Russian patent published in 2000 - IPC

Abstract RU 2143971 C1

FIELD: wood-working, applicable for configured pressing of parts of raw wood. SUBSTANCE: the device comprises punch press 2 with pusher 3 hinge-joined to actuating member 1 and a member protecting the blank against cracking, matrix 4 and finished part receptacle 5 attached to press lower plate 6. Pusher 3 is made in the form of bell- cranks installed circumferentially to punch 2 for radial movement. Matrix 4 has an internal cavity comprising an entry cone, cylindrical loading zone and a shape-forming zone-profile draw plate. The member protecting the blank against cranking is made in the form of projections on the ends of the lower arms of the bell-cranks enveloping the upper free end of the blank. Tapered surfaces engageable with the blank are positioned on these ends. Matrix 4 has an intermediate zone, which may be made in the form of one cylinder or in the form of several stepped cylindrical surfaces. EFFECT: enhanced quality of pressed parts, simplified design of the device. 5 cl, 7 dwg
