Title: Improvements in and relating to apparatus for the production of rubber rings
IPC: B29C67/00
Filed: 1955-07-01
Abstract: 844,843. Rolling rubber sealing rings. ANGUS & CO. Ltd., G., JAGGER E., T., and WALTON, B. June 25, 1956 [July 1, 1955 ; Oct. 10, 1955], Nos. 19050/55 and 28750/55. Class 87(2). Apparatus for rolling rubber rings, particularly for oil seals, each in the annular space between a mandrel and a coaxial cylinder, comprises a mandrel carrier 1 carrying an array of spaced parallel mandrels 2, each with a free end a cylinder block 5 coaxial with the mandrel carrier and having a set of spaced cylindrical apertures 6 respectively coaxial with the mandrels and means for effecting guided, axial, relative reciprocation of the mandrel carrier and cylinder block. The mandrel carrier 1 is bolted to the top of a cylindrical column 15 in which a hydraulic ram 16 is reciprocable to move a rod 4 connected to the block 5 and the reciprocation is effected by the alternate admission of oil through ports 17, 18 under the control of pneumatic plunger valves 21, 22 which are operated by the rod 4 through a roller 23 thereon, the stroke being adjustable by a screw 24. The locus of the stroke is progressively displaced axially during the reciprocation by the elevation of the valves 21, 22 as a unit by a slight amount at every stroke due to the admission of compressed air, past a non-return valve 25, into a lifting cylinder 26. An overriding manual control enables the rod 4 to be moved in either direction up to the full stroke of the ram 16. and the rod is first raised to its full extent to lift the cylinder block 5 and with it a cover 7 which carries an ejector carrier plate 11 with dependent ejector plungers 12. The plate 11 is free to turn on a boss 8 to permit the cover 7 to be attached to a lower housing 3 by a bayonet joint. The ring blanks are placed one each on the tapered free end of the mandrels 2. The rod 4 is lowered till the ejector plungers rest on top of the mandrels, when the flared mouths of the cylinders 6 have entrained the rubber blanks and -rolled them into the annular spaces. The cover 7 is closed on the lower housing 3. Heating for vulcanization is supplied by electrical elements 37, 38 and, to prevent gas-distension of the rubber, steam or compressed air is admitted through a port 36. The rod is reciprocated, the the progressive displacement of the locus of the stroke avoiding uneven compression of the material. After the rolling and vulcanizing operation the cover 7-is released and the rod 4 is raised to lift the cylinder block, initially to the top of the mandrels so that the ejector plungers 12 displace on to the tapered side of the mandrels any rubber rings which may have lodged in the cylinders 6. A valve (not shown), is then operated manually to admit fluid to pneumatic and hydraulic cylinders 31 and cause rods 10 to raise a stripper plate 9 which sweeps the rings off the mandrels. The second Provisional Specification mentions that the rings can be removed by a blast of air and that the means for varying the locus of the stroke may be a screw and nut.
