Tank Dishing Presses

01/08/2009 11:35 PM

I am looking to purchase a surplus or used press that will bump or press flat pie shaped blanks into double curved segments of dome and elliptical roofs for water tanks. The blanks are 8 feet in length and 5 feet in width on the wide end. Metal thickness is usually .25 to .50 A36 mild carbon steel plate.

The blanks can be formed a bump or a press at a time and be advanced into the press. In past have used old mechanical c frame presses with male and female dies.

I thought perhaps some of the members may work for companies that have surplus presses.

Thanks in advance for any help.

Do you need a press and the tooling also? I own a tool and die shop I could make a package deal for you, as you would need a good size press.

Tooling would be required at some point. At the moment we are using a male and female die with 8 foot radius made of hardened steel. The mail is on buttress threads and is turned counter or counter clockwise to achieve the desired bump radius.

With the right size press we will require various dies and will stack press.

What type, size, etc. presses do you have available ?

I am checking with Valley Equipment to see if they have any left. The Chinesse were in last year and may have bought everything that was not nailed down.

Here is their web site not everything is listed on the web site might be worth a phone call.

Would you prefer mechanical or hydraulic? I would think hydraulic would be better for forming a part.Mechanical would be better for punching.

Hydraulic or Mechanical would do the job. We currently use a 200 ton mechanical with a two foot diameter die the we turn clockwise or counter clockwise to change dish radius. It engages with a mechanical clutch and continues to cycle until disengaged. This allows sufficient time for the men to move the sheet side to side and advance into the machine as they come to the end of the side.

Hydraulic would be to slow for one piece at a time but would allow us to stack press several blanks at a time. Hydraulic would require dies for each of our standard tank heads. This would be a considerable investment but a huge savings in labor.

Does anyone have a formula for spring back. We are pressing .25 inch thick A-36 plates into knuckle pieces for large diameter tank heads. The blank is 6' long and pie shaped with a 5' width in back and 3' width in front. The longitude's radius is 5.5' and the horizontal varies from 15' on large end to 22' on small end. We have made a die with ribs that have the compound radius. The dies are about 6 inches wider than the blank. The dies are also 1" larger than the blanks. We intend to start by over pressing by .25 inches and continue hoping to find our way the hard way. We are wondering if there is a formula to calculate the spring back.
