itsmoked,
Are you talking about ladder programming or by the FBD method?
I have not yet even begun to understand ladder logic, however in the FBD method, I have made some progress. I have not been able to figure how to tell it it's the end. Also I used a XOR block before the first solonoid, then...
Ok, I have the plr, power supply, etc.
I bought the TECO SG2-20HR-D

I have been trying my hand at the logic. I guess I'm not very logical...
I'm using the fbd programming. (function block programming) because it seemed easier to understand...
I really don't mind the learning aspect of it. It is nothing that has to be done right now. I enjoy tinkering with this stuff. I have a machine shop and we have machining centers to do these parts, but the pipes are about 10ft long, and I only have a 40" stroke. An automatic drill? That won't...
Hi,
I'm am completely new to PLC's. I am building a shuttle table/clamp for a drill press. We are drilling several thousand pieces of 3/4" cpvc pipe. The holes go pependicular to the pipe at regular intervals. Some pipe will have the holes spaced at 1", while others will have them spaced at 1.5"...
to tell you the truth, i dont know if there are alignment pins or not. i have only seen the dryers a couple of times. However, knowing our customer and the conditions of the dryers, I doubt it. They have 3 out of 5 of this size dryer giving them fits. I think you're right, torquing the nuts to...
Yes,
I reiterated the fact about the lube to my customer. We have also lengthened the threaded length and corresponding shoulder to give a little extra room for the nut to travel.
We picked up the nuts from our local supplier, and we have found that these are also a part of the problem. About...
It costs so much more than a few bolts to have to shut the dryer down every other day than to spend a little more for the quality bolts. I truly think that the B7 is the best choice for these bolts. I am suggesting to my customer to try torqing the B7 bolts to 1148 ft bts. In the meantime, we...
I have attached a picture of the failed bolts. So, just to get this correct, They should try to torque the B7 studs to 1148 ft lbs? or even more? The picture is not very clear at all, but you can see that it is not breaking at the end of the thread, but about 1/4" away from the end of the...
The root of the thread has an .008 radius. We single point the thread on a cnc lathe. The break is not where the thread ends, but further up in the threads. We have not used grade 5 in several years, but that is just what the OEM recommends. Also OEM recommends 680 ft lbs. I don't know where...
I talked with the customer again this morning. He states that the manufacturer of the dryer sends grade 5 bolts on new machines. They suggest a torque of 680 ft lbs.
The customer says they changed from a coarse pitch to a fine pitch to gain strength at the root of the thread. (a 12TPI doesn't...
Hi,
I'm new here. What a great resource.
I have a machine shop and we have been making some bull gear splice bolts for one of our customers. The material is 4142 G&P Q&T BHN 255/321 ASTM A193 GR B7.
These bolts keep breaking and I am looking for an alternate material. These studs are 1 3/16Ø by...
