A kind of flask bushing provision for disengagement and method for dismounting
Technical field
The present invention relates to is a kind of machinery dismantling device, the instrument of a kind of sand box used for casting set pin sleeve dismounting and method for dismounting thereof.
Background technology
In casting field, flask molding casting belongs to the forging type of high dimensional accuracy, is matched with flask bushing by mould set frame set pin sleeve, it is ensured that the dimensional accuracy of modeling process, thus ensure the dimensional accuracy of product in its production process.For foundry production, there is the condition that many causes pin guide to wear and tear, it is therefore necessary to make regular check on replacing pin guide, boring for alignment pin, it uses screw fastening means to fix, and replacing is easier, and set pin sleeve uses transition interference fit, dismounting difficulty.The most conventional method for dismounting is:
1, simple hand frock, uses inertia to form the power of relative guide installation direction, repeatedly taps and taken off by guide, about 20 minutes operating times;
2, sandbox being used driving hanging out mo(u)lding line, on level land, artificial percussion takes out guide, about 18 minutes operating times;
Both the above method, write off set process is the longest, big to the working strength of operator, 2nd kind of method there is also certain potential safety hazard, during stopping line maintenance of equipment, would is that a time-consuming huge intensive work, if occurring changing the situation of guide in process of production, production line will be caused to stop line for a long time, production is impacted, the most unfavorable.
