Apparatus for automatically preparing the ends of tubes made of reinforced rubber.

摘要

1. An automatic machine for cutting a flexible pipe of reinforced rubber to the desired length and baring the cut ends in order to permit connection thereof, comprising : - a support (1) having a main face (2), - a first block (10) and a second block (25) which each have a longitudinal geometrical axis (14, 14') and which are mounted on said main face (2) of the support (1) and which each have means (12, 26) for displacement in the longitudinal direction of a reinforced flexible pipe and means (13, 13') for holding said same pipe, said first block (10) and said second block (25) being mounted displaceably with respect to the support (1) between on the one hand a position of displacement of the flexible pipe in which said displacement means (12, 26) and said holding means (13, 13') of the two blocks have their geometrical axes (14, 14') in alignment and together define a general axis (30) of displacement of a reinforced flexible pipe, the holding means (13, 13') which respectively form part of the two blocks being turned towards each other and separated by a given spacing (31) and, on the other hand, a baring position in which the two blocks (10, 25) are disposed inclinedly respectively on one side of said general axis (30) and on the opposite side of said general axis, - a cutting means (32) having a cutting blade (34) with said cutting blade disposed in a plane (P) perpendicular to said general axis (30) and substantially equidistant from the two holding means (13, 13') when the first block (10) and the second block (25) are in their inclined positions, - first and second baring units (36, 36') each having a first end fitted with a baring tool (42, 42') acting coaxially with respect to a baring axis (37, 37'), said units (36, 36') being mounted on the support (1) respectively on the above-mentioned side and opposite side of said general axis (30), each geometrical baring axis (37, 37') being disposed respectively in line with the geometrical axis (14, 14') of the entrainment and holding means of the corresponding block (10, 25) when same is in its baring position, and - drive members (7, 7', 23, 23', 40, 40') such as jacks which are disposed on the one hand to produce relative movement towards each other of the blocks (10, 25) and the cutting means (32) in order to cut a pipe which is clamped in the holding means (13, 13') and on the other hand to displace the blocks (10, 25) between their displacement position and their baring position.
