Press action simulator for aerial cam set up
View Patent ↗Adjustment of the tools ( 24 ) on the tool holder ( 10 ) in an Aerial Cam of a metal stamping press may be readily effected by opening the press to remove the upper die ( 14 ) from the stamping area and then removing the tool holder ( 10 ) on the driver ( 18 ) for controlled reciprocation simulating normal operation of the press. The tools ( 24 ) may then be adjusted in relation to the workpiece without the interference of the press dies ( 14 and 20 ).
1. A method of facilitating adjustment of tools on a tool holder in an aerial cam without the presence of an upper die obstructing access to a die work area comprising:
removing the upper die from the die work area;
removing the tool holder from a cam adapter on an upper shoe of a press and mounting the tool holder on a driver for sliding movement as in normal operation of an aerial die;
mounting an installation bracket on the tool holder;
using a key to limit the movement of the bracket, thereby limiting movement of the tool holder on the driver
shifting the tool holder toward and from a workpiece independent of the cam adapter to simulate the sliding action of the tool holder on the driver when the upper die closes and opens;
during such simulated sliding action of the tool holder adjusting the tools on the tool holder in relation to the workpiece; and
remounting the tool holder on the cam adapter on the upper die.
2. The method of claim 1 characterized by connecting a tool holder actuator between the tool holder and the driver for moving the tool holder reciprocally on the driver to simulate the sliding action of the tool holder on the driver.
3. The method of claim 2 wherein said actuator comprises one portion connected to the tool holder and another portion connected to the driver and a third portion extending between the first and second portions and operable to shift the first portion relative to the second portion to move tools carried by the tool holder toward and away from a workpiece.
4. The method of claim 1 characterized by mounting the tool holder on the driver with opposed wearing surfaces of the tool holder and driver in full engagement whereby there are no gaps between such wear surfaces.
5. The method of claim 1 characterized by pushing the tool holder against the driver to urge opposed wear surfaces thereof toward each other to eliminate gaps therebetween.
6. An apparatus for simulating the sliding action of a tool holder on a driver in an aerial cam when dies of the aerial cam are open thereby facilitating adjustment of tools on the tool holder in relation to a workpiece, comprising:
an installation bracket for securement to the tool holder;
a key for attachment to the driver and in cooperation with the installation bracket to limit movement of the tool holder on the driver;
an adjustment member for connecting the key to the installation bracket; and the adjustment member controllably shifting the tool holder toward and from a workpiece simulating the action when a cam adapter on an upper die slidably shifts the tool holder on the driver.
7. The apparatus of claim 6 characterized by said adjustment member comprising a threaded part rotatably threadedly connected to one of said key and bracket and operable upon rotation to shift the tool holder on the driver to simulate normal operation of the tool holder on the driver.
8. The apparatus of claim 6 wherein said key overlies said bracket, and an adjustment member cooperates with the bracket and key to urge the key away from the bracket to push the tool holder against the driver and eliminate gaps between opposed wear surfaces thereof.
