Which Component is On This Picture?

It's a bolt! If you would notice the link you provided. It's an automotive wheel bolt. The process shown is the cold forming of the head.

Can be those explanation, sentences near pictures and pictures themself used when describing classical ''M'' bolts and how are they made? Those pictures look very weird for M bolt. Never seen the M bolt like that - it looks like it is produced together with nut but bolts aren't produced WITH nuts at the same time. Never seen four different diameters right after ''classical'' bolt is pushed away from machine (= JUST been produced). However, I have been searching for good explanation of cold heading for a long time and don't want to lose this article.

Each stage represents the addition of features to the prior stage. The pictures do not provide a clear idea of the net finished part. Here are drawings of various cold formed bolts.

This is just the first part of the articles. But do those pictures relate to all type of bolts on the topic How are they made? Or just bolts for wheels? Its extremly complicated for me to translate those sentences, specially the ones near pictures and one sentence can take up to two hours also. Its not easy. However, I would say that the answer is ''no, the picture don't relate to all type of bolts''. I worked 8 months on practical work in the manufactory of bolts and there were no types of bolts which such a hole inside the bolt's head. If pictures are not related to classical bolts, could I get the replacement picture that could replace pictures number 4, 5, 6 and 7? Picture 1, 2 and 3 is probably the same for every single type of bolt, so including classical M bolts with one or two sizes of diameters under the head.

I think the text is related to all types of bolts but pictures aren't.

Here are the rest of parts to this article:

Could anyone please assist with those four pictures and sentence(s) near pictures? They probably aren't for ''classical bolts''... But the main content on the left side is for every single bolt type.

I've just read through the first nominated link.

Since English is not your primary language I'll keep sentences short.

Maybe they are making a "hex drive" bolt. Sometimes called "allen" drive.

These have hexagonal "hole" in centre of head.

Yes, as member ozzb already told me, bolt, which is shown on those 7, or better say 5 (because on first two is just a wire) pictures, can be used for wheels. The picture number 3 on the first link (first part of article) can be understandable as ANY type of bolt but this cannot be said for rest of the pictures (4, 5, 6 and 7).

I will repeat my ''question'':

Could anyone please provide me the pictures (or it can be just one single) that could ''replace'' fourth, 5th, 6th and 7th on the first link link (the one in my first post id=1560)? With ''replace'' I meant that I need the picture(s) which says the same as those four do BUT can be understandable also for classical M bolts? Also those four sentences near four pictures would be probably edited.

The reason why I don't need to replace the first three pictures is because they can be understandable as they are showing/describing any type of bolt.

The content on the left side, and also on other links provided in my previouns post, can be understandable as it is describing production of ANY type of bolt, am I correct?

Its is only giving you a 'sense' of what takes place during cold heading of a bolt process. Are the drawings unclear..yes, because its intent is not to give you exact drawings of seven sets of tools but instead give more of a understanding of what happens as the part is deformed in each stage. Im sure with more surfing you MAY find something.

The pictures in the article are clear. They are showing you what comes out at each stage and the last stage is the bolt with the complete head.

Acutally it is not. Stage number five is backward extrusion, but yet it doesnt show this extrusion at all. It is lacking some hidden lines, in fact it looks identical to blow number two. Station seven details are finishing blow "large shoulder is trimmed' when something is trimmed material is being cut off(usually), yet it doesnt show that either.

I agree. Poor illustrations. Especially for someone with limited English skills.

So my question, as asked in post number 7, remains. Would appreciate an answer. Thank you in advance.

My question is: What is shown on those pictures (i know only for first two - its a wire)? It might be understandable from the text but Im not native English speaker and Im having some issues with understanding the text. The word ''shoulder'' doesn't help me much. With ''shoulder'' I understand the part of bolt which is under head, so the part with smaller diameter but this is already formed in picture number 3 so I don't know what is shown on pictures 4, 5, 6 and 7?

Another proof that (unfortunately for me) this is not bolt is picture number 5; there is no ''center hole'' in the bolt.

Im sure there is some sort of 'center/profile' but they dont give you a top view, so it could look like anything, this would be done to lighten the part so less steel is used.

Also: whatever this is, could anyone ''convert'' with better sentence the text near pictures from 4 to 7 so it can be more trusty described for

Centering marks are used in the next 'die' because the part design must need them for part flow/forming of the next process. They do not do a very good job showing this, but that article isnt intended for that. Each die has certain characteristics that carry over to the next operation which they require to avoid chevrons, laps etc..

cold fusion thank you for reply but I have no idea what are you trying to say? I need the picture(s) (no matter one or four) which will have the same meaning as 4, 5, 6 and 7 BUT it/they should be related to all types of bolts - so also for classical M bolt and not just the wheel bolt?

The reason for this is because Im trying to do some project in my native language for university on how bolts are produced and cold heading is just first out of 5 main processes that should be described.

Explanation in the main content on the pages are related to all types of bolts so its no problem in that. I don't know yet what I will do with the sentences near the pictures but now Im worried about picture(s) that will replace those four ones. I have been trying to search through google as well as on this web site (cartech.com/techarticles) but no luck so far. Pictures on other pages (parts) of the same article cannot replaced mentoined four. So Im keep trying to search the correct one(s).
