Abstract

620,070. Screwing; die-heads. LANDIS MACHINE CO. Dec. 18, 1946, No. 37320. Convention date, March 12. [Class 83 (iii)] In a pipe-screwing machine, the end of the pipe 34 is supported by a centring disc 106 engaging inside the pipe and secured to a plunger 82 rotatably and slidably mounted in the die head 44 and urged forward by a spring 102 or other resilient means. The initial position of the plunger forward of the die head can be set by nuts 100 on a rod 98 attached to the plunger. The end cap 78 is fitted with a thrust bearing 94 and plate 96, and holes 114 and 116 are provided for the escape of air from the plunger bore. Cuttings are removed from the bore 68 through a hole in the flange 72 and an oil nipple 84 is provided, the oil being retained by a seal 86. The support is applied to a machine having a die-head carriage 40 advanced by a lead screw 42, and having taper threading mechanism 50 operating the die-head through levers 56, 58 and 60. The pipe is carried within a rotating spindle 24 having two chucks 30, 32 operated by a hydraulic or other motor 38, the rear chuck 30 gripping the pipe to rotate it, and the forward chuck being adjusted so as to serve as a non-gripping guide for the pipe.
