stamped wrenches
« on: July 29, 2011, 04:26:21 PM »
Id like to know the process for making a flat stamped steel wrench in the late 20. I am assuming that there was an initial steel sheet brought in and that some sort of cookie cutter punching press cut them out. So I guess if this is it than they were punched out cold and that would take a tremendous press with lots of force, any ideas how many could be punched out at one time, what would have been the process within that time frame. Are there are vintage photos floating around that anyone has of these machines that could do this work. Thanks
Always looking for what interests me, anything early Dodge Brothers/Graham Brothers trucks ( pre 1932 or so ) and slant six / Super six parts.

Bring up the google front page, and click on the videos search button. Then, type in "how wrenches are made", and you will see not only how wrenches are made, but pliers, sockets, etc. Very Interesting!!!!. As far as the old stamp cut method, I have seen shears that would cut thru 3/8" steel like butter, so I imagine the old stamed wrenches were cut like a cookie cutter, with a series of die cutters, but I could not find an old video of it.

Thank-you Wayne, if I look at the edges of these wrenches ( they are approx 1/8 thick ) I see that it appears the centers are slightly concaved ( very slightly ) and there are very minimal lines drawn thru them in places running up and down so I am thinking that if a large press were to punch these out that the press would hit the wrench and initially drag the steel which would made and ever so slight ridge on the edge and again as the press went thru the wrench it would again have a tendency to drag the steel making the outer ridge there by forming the slightly concave center.
I would like to confirm this, I would  like to know how many could be punched at one time, was the machine set-up ( as Rusty described at one point ) with a sheet of steel no wider than a wrench and that steel ran thru a machine that would punch one at a time or maybe the sheet was 4 by 6 for example and the press punched out a hundred at a time.
These questions maybe describe better what I am seeking. I will check out the videos if my comp will let me, thanks again
