Title: Improvements in pressing, stamping, drawing, shearing or the like machines
IPC: B21D43/04
Filed: 1953-04-07
Abstract: 738,202. Stamping; shearing. FEINPRUEF FEINMESSUND PRUEFGERAETE GES. April 7, 1953 [April 4, 1952], No. 9295/53. Classes 83 (3) and 83 (4). Machine-tool details.-A workpiece feed unit for stamping and shearing machines has a work holder displaceable from a feed position to a work position and vice versa and is attachable to and detachable from the machine, the driving and control members for the work holder being included therein. The unit 3 is attached to the work-table of the machine and the workpiece 5 is located in an apertme in a holder 17 and supported on a cover-slide 18 beneath the holder. The holder and cover-slide are reciprocated by a rack and pinion 12 operating a pair of cranks 13 engaging the holder-slide 15, said rack being reciprocated by a solenoid 10 controlled by a pedal 7. The holder is mounted in a vertically-adjustable carrier 16. The pedal 7 also operates the switch controlling the machine, but safety means prevent operation of the tool until the holder has positioned the blank in the machine. The safety means consist of a sliding catch-plate 23, a rod 24 having an adjustable stop 25 and a switchactuating rod 21. On forward movement of the holder 17 the rod 24 follows until the stop 25 abuts the catch-plate 23, which is moved until a hole therein aligns with a head 22 on the rod 21 when the work is positioned, so that the rod, which is attached to the pedal 7, is depressed and actuates the switch 11 by a collar 27. When the lever is released the head 22 moves clear of the hole in the catch-plate and a spring 28 returns the catch-plate to its initial position which prevents downward movement of the rod. During the feeding stroke of the holder the cover slide is arrested by the lower die 2 of the machine whilst the holder continues to the end of its stroke, whereupon a spring-loaded pawl 19 moves upwards and locks the holder and slide in position. On the return movement of the holder and slide the blank 5 falls through the aperture, Fig. 7, and is discharged from the machine. The pawl works automatically but may also be hand operated at 20. When the holder has returned to its initial position the pawl is released and the cover-slide closes the aperture in the holder ready to receive the next blank. The work holder may be constructed as a die and may be operated hydraulically or pneumatically.

Abstract: A strip of material (9) which moves upwardly (between plates 27, 29) through a chamber (3) is heated by the discharge of hot gas as a multiplicity of jets on to its surface in a direction normal to that surface, the gases, after striking <PICT:1100892/C6-C7/1> the strip (9) moving laterally of the strip to an exhaust passage extending along one edge of the strip (9).  The gases e.g. hydrogen, air an inert gas, or gaseous products of combustion) are circulated by a fan 11 and heated in a chamber 21 by a gas burner 17 (burning, e.g. town gas) or alternatively an electric heater or an indirect heat exchanger.  The gases pass from chamber 21, through ducting and downwards into plenum chambers 23, 25 horizontally into ducts 47 formed between baffles 41 and pass through a plurality of circular apertures 31 in plates 27, 29 to impinge on the strip (9).  The ducts 47 extend over the height of the chamber (3) through which the strip (9) passes, and is divided vertically into three portions, a central portion in which baffles 41 are vertical, and upper and lower portions in which baffles 41 are slightly inclined to the vertical, and across the strip, to enable even heating across the width of strip (9).  Plates (not shown) over the upper and lower portions prevent gases entering the ducts except via the central portion, where the entrance is controlled by a plurality of individually controllable dampers 49. The spent gases may exhaust to atmosphere or be returned to the fan inlet.  A second exhaust passage may be provided along the other edge of the strip (9), the gases from which being exhausted to atmosphere, or returned to fan 11, or passed to the inlet of a second fan serving a second heater, in which case each heater may supply either both plenum chambers or its respective plenum chamber.  In the case of the spent gases being exhausted to air, they may be used to pre-heat the air entering the fan(s) or to pre-heat the strip (9).
