Description
Technical field
The invention belongs to hydraulic press renovation technique field, be specifically related to a kind of side that strengthens oil cylinder oil inlet passage conveyance capacityMethod and device, be applicable to substitute the transformation side that increases fuel feed hole quantity or expand original fuel feed hole diameter on original oil cylinderMethod.
Background technology
Generally, master cylinder in hydraulic press especially in, in large hydraulic press, (comprise hydraulic extrusion press, forgingLiquid making press, hydralic stamping press etc.), belong to the first important parts. Along with the ability of different hydraulic presses from several million Ns greatly to mistake100000000 Ns, the diameter of its master cylinder also can be from more than greatly to 3 of hundreds of millimeter meter, and the weight of master cylinder also can be from several tons greatly to exceeding hundredTon, only the cost of single oil cylinder will exceed millions of yuans, and cost is very expensive, and its total manufacturing cost becomes at complete machineThe larger ratio of occupation ratio in this; Due to the force-bearing situation complexity of master cylinder, severe, any unnecessary hole, groove, wedge angle,Minor radius fillet and fault in material all can cause that its stress is in various degree concentrated and the decline of oil cylinder intensity, and severe patient can be directlyCause oil cylinder fracture failure, cause thus complete machine loss of function, economic loss is huge. So, in the transformation of this kind equipment, asWhat avoids weakening and damage to master cylinder intensity is very important.
At present, the transformation process of hydraulic press is by strengthening fuel supply flow rate to master cylinder, realizes and improves master cylinderPlunger motion speed, reaches the object that improves hydraulic press operating rate. After the fuel delivery of master cylinder is strengthened, the original oil-feed of oil cylinderThe conveyance capacity relative deficiency of mouth. In order to improve the conveyance capacity of oil-in, existing modification scheme is mainly to increase on oil cylinderThe diameter of former fuel feed hole, or on oil cylinder, newly increase the quantity of fuel feed hole, although this modification scheme can strengthen overcurrent energyPower, but this method has obvious drawback, and it can weaken oil cylinder intensity, cause stress to concentrate, and causes oil cylinder safety coefficientReduction, can directly cause what is more oil cylinder work time to be broken, cause hydraulic press complete machine ability to work to lose efficacy.
Master cylinder and the prefill valve of original hydraulic press directly link together, and as shown in Figure 1, former high pressure fuel feed hole is as A in figureShown in, if directly the original aperture shown in A in figure is strengthened, or increase the quantity of fuel feed hole at other position, thisAlthough way has reached the object of the conveyance capacity that strengthens master cylinder high pressure fuel feed hole, has significantly weakened the original of oil cylinder and has establishedMeter intensity, has newly increased the hole that as far as possible avoid, has formed new stress raiser, reduces the fatigue of this mill type cylinderIn the life-span, even master cylinder short term strength is caused and had a strong impact on; Especially work as the reserved safety coefficient of master cylinder not high, or master cylinder isWhile concentrating sensitive material to manufacture by stress, this destruction will be more serious. Moreover, transform above class mill type cylinder at thisProcessing, exists and a series of retrofit works with difficulty such as needs to dismantle, lift, transport, reprocess, reinstall, and causesThe increasing of transformation risk, cost up, cycle stretch-out. So, this remodeling method in, large hydraulic press, drawback isMany, should not adopt.
Summary of the invention
