On the processing of eye bolts

To make a pipe with a tightening bolt, if the ring part of the screw part of the screw is not used, if the batch processing can be used for processing as a whole.

Such as as long as a few pieces, you can use round steel simmer system processing ring, threaded rod material can use 10 #, 20 #, Q235 production, but should not use 16Mn, 35 # steel, cold after welding, generally do not require heat treatment, Should be calculated in terms of diameter, according to the material of the allowable stress, consider more than 1.3 times the safety factor. Round to the standard thread.

Ring bolts should be made of 20 or 25 steel GB699 production, but also the overall forging, normalizing treatment.

You can understand your boss, the length of standard parts is not enough, generally their own processing. But the pipe hanger selection ring suitable? You did not say the scene, I am not good to comment. Forging certainly can not do, and normalizing the heating temperature will be slightly higher it, heating to 860 degrees Celsius, after the use of forced ventilation cooling insulation. But must not be cold. 2T weight, taking into account the time on the suspension, the safety period of bolt diameter M30 ~ M36 enough

Only 2 tons only, just to find the root of the coarse point of the bar, a milling of the double plane and then drilling chamfer, the rest of the car M36 thread according to the required length of interception. Even if the waste of material and how much money ah. Since the decision to do their own processing do not consider whether the requirements of the standard parts, and do not take the standard ring to find their own trouble and no heat treatment, this thing is only the name of the ring fills, or you simply change the name of a rod who can not pick you Problems, 25 steel M36 as long as the lifting angle hanging vertical hanging 4 tons are all right. Heated curved ring but not good, no more than the number of welding safety. Brief description of processing technology and technical requirements of eyebolts.
