Kallsme Posted February 9, 2006 Share Posted February 9, 2006 Here is a series of pictures how to forge a big shaft to Volvo Powertrain transmissions from a 170mm rounbar, and a lengt och 160mm.

HWooldridge Posted February 10, 2006 Share Posted February 10, 2006 How many of these do you make for Volvo? Is it for research purposes or in production quantities? Quote Link to comment Share on other sites More sharing options...
Ed Thomas Posted February 10, 2006 Share Posted February 10, 2006 Hi, Roger. Do you do the machining afterward? What is the steel type? Did you have an original pattern to make the swages? Or did you make the first one yourself to make the swages? Which hammer is that one? I like your pictures of transferring control of the tongs. You obviously work well together. Are your forges gas or oil? (They look like gas) Thanks again for sharing. Quote Link to comment Share on other sites More sharing options...
mike-hr Posted February 10, 2006 Share Posted February 10, 2006 You do amazing work. Thank you for posting pictures of the things you make. Please keep posting pictures and don't ever leave us! Quote Link to comment Share on other sites More sharing options...
Strine Posted February 10, 2006 Share Posted February 10, 2006 I get the gist. Start with a whopping great piece of hot stuff, get it under a whopping great hammer with the aid of whopping great pairs of tongs and let it rip. Eh presto a shaft. I agree with comments re the saftey glasses...and for "Volvo" of all manufacturers :wink: Are the parking lights on the hammer kept on day and night? And I totally concur with comments about the nature of the work. Jolly well done...keep up the good work and the posts. Great stuff...love to see more Quote Link to comment Share on other sites More sharing options...

Kallsme Posted February 10, 2006 Author Share Posted February 10, 2006 Hello folks This is only for the prototype workshop at Volvo Powertrain. We do about 30 pices of this type and year, so it Quote Link to comment Share on other sites More sharing options...
Ed Thomas Posted February 10, 2006 Share Posted February 10, 2006 Roger: Thanks for the answers. Your spelling and English grammar is bettern than most of us! I should have recognized the soot on the forge doors as evidence that you burn diesel oil, not gas. Do you normally fit your swages with springs, or just hinges? I see the main one is a top and bottom tool separated, right? But the one for the shaft looks like it is joined at the operator's end.

Kallsme Posted February 11, 2006 Author Share Posted February 11, 2006 Yes you notice that right. The reson for that is, if you fit springs on the big swages you will not be able to lift the tool up on the dies because they been to heavy. This swages weigh nearly 30kilos each And another reason is, lets say , after ten hit with the hammer you hawe to lift the shaft and the swages to blow away slag (is that the right word ??) in the lower swages so the surface will be good. Roundbar swages is fitted with springs up to about 70mm. Roger Quote Link to comment Share on other sites More sharing options...
Ironscot Posted February 14, 2006 Share Posted February 14, 2006 I don't have a particular questions.

Kallsme Posted February 14, 2006 Author Share Posted February 14, 2006 Ironscot, If you come to Sweden, I promisse that you are welcome to "play" with my hammer in my shop, for a day. Roger Quote Link to comment Share on other sites More sharing options...
sqeezplay Posted February 14, 2006 Share Posted February 14, 2006 have you ever dropped a piece of white hot steel that big when forging? or have it shoot out from under the hammer? i bet that could burn a mighty big hole! Quote Link to comment Share on other sites More sharing options...
Kallsme Posted February 15, 2006 Author Share Posted February 15, 2006 No I hawe newer drop a pices that big in 28years, (knock on wood) And i newer got injured during those years either when blacksmithing. Roger Quote Link to comment Share on other sites More sharing options...
