Machine removing weld bead projections arising when plastic frames for e.g. doors and windows are welded

摘要

This machine removes the projecting weld bead between plastic corner profile sections (2, 2). It comprises a frame (1) with side insertion opening (4) into which the corner with the weld bead is first introduced. Pneumatic cylinders (10, 10, 10) move a pressure clamp (9) vertically downwards to hold the sections down onto the resting table (5), clamping them there. A two-jaw clamping system (7, 7) working through a long slot (6) in the table travels up, actuated by pneumatic cylinder (8), to clamp the loose corner profile strips temporarily, oriented along the length, with subsequent release.
