Abstract

572,845. Angular bending. MILLARD, E. H., and WILSON, F. R. July 14, 1943, No. 11469. Convention date; April 3. [Class 83 (iv)] A plate is bent into a trough or like form, without any part of the metal at any time being gripped, by means of relatively movable members 11, 17, which engage it at relatively spaced parallel lines to bend it into a shallow channel P, Fig. 4, and then bending the end portions, Fig. 7, in the reverse direction into a plane parallel to the plane of the central portion p. The member 17 has pedestals 22, with adjusting shims 25 and wear pieces 24 having rounded corners c, and a central abutment 23. The member 11 has a central depending abutment 14 with rounded corners a supported by bolts 13 and backed by adjusting shims 15, and small abutments 16 spaced to align with the pedestals 22. The member 11 is fixed to a frame 8, Fig. 1, and the member 17 is moved on guides 21 by a piston 19 until it reaches the position shown in Fig. 7 and the plate has been given its finished form F without gripping. The members 11, 17 may be long enough to operate on the whole plate, but, as shown, there are a number of bending units arranged along the length of the plate, all the pistons 19, Fig. 9, being raised simultaneously by pressure fluid from a pump P<1> admitted by a solenoid-operated valve A when a switch B is operated. An adjustable contact F engages a switch S, when the operation is finished, and reverses the valve A to connect the cylinders 20 to exhaust K.
