Problems solved by technology

The disadvantage of this method is that it takes 1-1.5 seconds for the press to accelerate from standstill to maximum speed, which is much slower than accelerating with a clutch, and thus takes up 90% of the production cycle (usually the entire production cycle is about 5 seconds). A majority

Embodiment approach

[0100] Figure 8 is a schematic diagram of a pressing cycle according to an improved method of operating a mechanical press, according to one embodiment of the present invention. The figure shows that, in this case rotating in a clockwise direction, the press approaches the deceleration point D at a point 8 just before the point UC. Deceleration begins and the press turns through UC, at which point the unloader / loader enters the press to unload the part. The press decelerates continuously at maximum torque and at Z 1 passing through zero speed, and then reversed to turn from Z 1 Small angle to R'. At point R' the press accelerates again in the forward clockwise direction with full torque and then at Z 2 ′ at zero velocity for the second time and from Z 2 ' Accelerate towards DP to pass DP towards point 1 at maximum possible speed. When the press reaches the DP, the loading / unloading robot, already loaded with new parts, has to be moved out of the press. In the pressing ph...

Abstract

A method for synchronising a first machine of a manufacturing process section arranged to carry out a production cycle comprising a working part and a non-working part, which said first machine is operated in conjunction with at least one second machine. The first machine carries out a process during the working part of the cycle on a workpiece which is loaded into and/or unloaded out of said first machine by said at least one second machine during the non-working part of each process cycle. The first machine is preferably a mechanical press and the second machine is preferably an industrial robot arranged to carry out a loader and/or unloader function. A system for carrying out the method and a computer program are also described.

Description

technical field [0001] The invention relates to an improved method for synchronizing a first machine for manufacturing a machining part and at least one second machine for loading and / or unloading the first machine. In particular, the invention discloses a machining section in which a first machine comprises a mechanical press of the type used for pressing, punching or punching metal parts from blanks. The press is driven by at least one electric motor, the second machine is a loading or unloading machine, such as an industrial robot. Background technique [0002] Mechanical presses such as connecting rod presses, crank presses or eccentric presses are often used for the production of automotive parts stamped or pressed from steel billets. At present, the vast majority of large mechanical presses are driven by flywheels. The function of the flywheel is to store the necessary energy to complete the pressing operation. A relatively low power motor drives the flywheel so tha...
