Title: Improvements in and relating to spring hammers
IPC: B21J7/12
Filed: 1949-06-28
Abstract: 664,864. Power hammers. MASCHINENFABRIK ANDRITZ AKT.-GES., and PIRKNER, I. June 28, 1949 [July 10, 1948], No. 17105/49. Class 83 (iv). A spring hammer driven by a crank or an eccentric is characterized in that the driving mechanism is connected with a fly-wheel through a releasable coupling and that the hammer-head is balanced by springs, compressed air pistons and the like. The frame 1 has bearings 2 for the crank-shaft 3, on which is mounted a coupling disc 4 slidable along a key 5 and co-operating with the coned driving flywheel 15 mounted on ball-bearings 14 at one end of the shaft. A brake pulley 6 is keyed on the other end of the shaft 3. The hammer head 11 is guided by the frame 1 and is actuated by a connecting-bar 7 attached to the shaft 3 and a laminated spring 10 supported in bearing 9. The head is balanced by the spring 16. The spring 10 exerts a pressure on the forging during and after the hammer blow and a band brake 17 on the brake pulley 6 takes up the tension of the spring 10 and a clutch (Fig. 4) consisting of a strap 19, outer and inner shoes 20, 21 connected by a bell-crank 22 and pressed by a spring 23 against a rim 18 on the pulley 6, prevents the spring tension from rotating the shaft 3. For automatic operation the coupling disc 4 has a cam 24 on which runs a roller 25 at one end of a bell-crank lever 26, the other end being pivotally attached to a pull-back latch member 28 which rests on a lug 27 on the lever 26. By depressing a pedal 29 a shaft 32 is rotated through bevel gearing and two rocking levers 33 mounted on the shaft 32 throw the coupling disc 4 into engagement. When starting, the roller 25 is in the swell of the cam 24 and the latch 28 is out of engagement with a connecting-rod 34 joining the rocking-levers 33 which can thus move the disc 4 into engagement with the fly-wheel 15. On rotation of the shaft 3 and the cam 24 the roller 25 with the bell-crank 26 moved downwards due to the cam profile and by displacing the latch member 28 and lowering the lug 27 the latch 28 engages the rod 34. As the roller ascends the cam the latch 28 pulls the rocking levers 33 back and disconnects the fly-wheel from the hammer. At the end of its pull-back motion the latch member 28 is lifted by the lug 27 off the rod 34. Any play in the coupling rods is taken up by a spring 36. The hammer may be used for sitting blows delivered singly or in succession and may also be made to function automatically.
