Abstract
The invention discloses a method and device for controlling a crankshaft for a forging machine. The method includes the steps of judging whether the crankshaft falls back into a preparation area or not, if the crankshaft does not fall back into the preparation area, adopting the inching mode to control the crankshaft to descend in an inching mode until the rotation position of the crankshaft reaches or exceeds a falling point of the crankshaft, and starting a rapid return mode to control the crankshaft to be driven by a power mechanism to automatically ascend to be stopped in the preparation area. According to the method and device, the process that the crankshaft falls back to the preparation area is divided into two stages; in the first stage, the inching control mode is adopted for the descending process of the crankshaft from the original point to the falling point of the crankshaft; in the second stage, the rapid return mode is adopted for the process that the crankshaft passes through the falling point and ascends to reach an upper dead point. In this way, the trouble that frequent and repeated inching crankshaft operation is adopted in the whole falling-back process of the crankshaft is avoided, the falling-back control intelligent degree of the crankshaft is improved, the safety performance of the crankshaft in the descending process is guaranteed, and meanwhile the operation efficiency of the crankshaft is improved.
Description
Technical field
The present invention relates to forging press field, especially, relate to a kind of forging press bent axle control method and control device.
Background technology
Forging press generally comprises adjusting microinching pattern and automatic mode, in adjusting microinching mode process, and the bent axle of forging press crawl progressively under manual operation; Under automatic mode, the rotation that the bent axle of forging press goes round and begins again under the promotion of driving mechanism, and then drive punching module to carry out punching operation.
Fall after rise in the time preparing region because the top dead-centre of the bent axle of forging press only has, the single stroke of the punching module of guarantee forging press there will not be overshoot or the two degree phenomenon that falls, therefore need to guarantee in each stroke, bent axle can fall after rise preparatively to preparing region.When adjusting slide position, break down or other reasons interrupts bent axle when operation, or when bent axle is prepared region because the problem of running precision does not stop at, need to use adjusting microinching control mode and observe cam angle degree and show, slowly put dynamic crankshaft to preparing region, when drawing velocity fast, crawl is easy to occur overshoot, sometimes will carry out frequently crawl repeatedly, and bent axle just can stop at prepares region.Not only consumption energy consuming time of existing bent axle backhaul control method, and efficiency is low.
