Builds New Punching and Shearing Machine To provide for the handling of a wider range of material including the lastest standard shapes and sections, the Steel Works Ocking, Dusseldorf, Germany, has redesigned its combina- MARINE REVIEW tion punching and shearing machine and is introduc- ing through its American repre- sentative, Amplex, Inc, New York a new triple com- bination machine. This machine, which is shown in the iaccompanying illustration is claimed to occupy little floor space and work can be done without the loss of time from changing tools. As shown in tthe il- lustration, the operator’s side of the. machine is free from flywheel and driving gears, all of these being placed on the op- posite side. A slan- ting centering slide is provided so .,; that, “mitterine=. cits 17 cam «be made without lifting the angle bar to be cut. The plate shear has extremely long knives varying from 13 to 16. inches. depending upon the size of the machine. The punch is arranged. for punching both webs and flanges of structural shapes and the height of the throat is designed to meet the increasing demands for handling board flanged shapes. A lowering device on the punch enables the operator to locate the center mark. Both hand and foot levers are provided to throw the machine into gear. The bar and angle cutter cuts any structural shape, but the — standard equipment | accommo- dates the cutting of rounds, squares, angles and tees only. After a change of knives, beams and channels may be AIt. To make the machine durable the frame has been made of cast steel and the sides have been made of steel also. These machines are made in several sizes ranging from those which will split 14-inch plates, cut 3%-inch angles and punch %-inch holes in %-inch material up to ‘those which will split 1:4-inch plates, cut 8 x 8 x %-inch angles and punch 134-inch holes in 1- inch material.
