800-Ton Danly Rebuild

Adding project to Projects

Our team completely rebuilt this 800-ton Danly 4-point stamping press. We disassembled, cleaned, and inspected each press component to ensure proper repairs were made. We manufactured new tie rod nuts, adjustment nuts, worm gears, worm shafts, slide adjust bearing retainers, slide adjust shafts, and eccentric pins.

Our Machinists machined the bed, bolster and slide flat and parallel, and repaired the damaged T-slots in the slide face and bolster face to allow proper die connection. Our welders repaired cracks in the slide, and eccentric gears.

Our Engineers designed a new metered lubrication system utilizing the existing reservoir and drainage systems and worked with outside contractors to install the press pit, support frame and floor plating.

Our technicians installed new divider valves, lubrication lines and hoses, as well as a new recirculating pump, filters, gauges, and cycle switches.  Our electricians stripped out the old wiring and wired new control panels with PLC programed to work with the new metered lubrication system and upgraded the motor, brake monitor, and tonnage monitor. Our team assisted in assembling the press and leveling the press and performed tests to ensure the press and all safety systems were running properly.

Minster Knuckle Joint Press

minister knuckle joint press yield strength

We provided servicemen, equipment and trucking to load this Minster Knuckle Joint Press and transport it to our facility. The machine was completely disassembled, cleaned and inspected. The customer wanted to increase the shut height of the press and widen the die space area. We completed a stress analysis to determine the maximum modifications that could be safely made, uprights were then modified from a 34 to 38 inch clear span between uprights for 15 3/8 inches above bolster face.

We removed enough material from the upright to allow a 37 inch wide slide plate clearance during the entire press stroke and adjustment. We manufactured a T-slotted bolster with die lifter slots to match their existing tooling. Increased the slide face flange to 37 L/R x 36 F/B inches and cut standard ¾ inch T-slots into the slide adapter face. We lengthened the existing counterbalance rod to accommodate the modified shut height adjustment. We provided the material and engineering to design an electrically powered wedge adjustment mechanism that replaced the manual adjustment. The original control was stripped off the press control and replaced with a Link 5000 control. We also calibrated the tonnage monitor and tested the linear tracking in our facility. The press was assembled in our facility where we replaced, troubleshot and tested the lubrication, control, and pneumatic systems to ensure proper operation. We transported the press to our customer\’s facility in Nebraska and rigged it into place and integrated the press to the feed line.
