Abstract
526,186. Blank-punching. BRITISH THOMSON-HOUSTON CO., Ltd. March 9, 1939, No. 7697. Convention date, March 9, 1938. [Class 83 (iii)] An automatic stamping and cutting press particularly for making two different stampedout parts, such as stator and rotor stampings, from a strip 20, has the tool carriers 1, 2 mounted on rams which move together horizontally and are driven by synchronized cranks with different throws so that the tools move at different speeds to obtain a low resultant cutting speed. One ram may have a lag or lead or the stroke lengths may be varied to alter the cutting speed. The crankshafts 6, 7 carry flywheels 8, 9, and may be driven by synchronized motors 17, 18, or by a single motor through gearing. The blanks are stripped by ejectors 12, 13, and drop past a separating device 14 on to separate conveyers 15, 16, which convey the blanks to separate stacks 19 on opposite sides of the machine. The strip may be fed manually or automatically.
