A press frame assembly includes a base plate, a load cell, and an overload protection element; a first plate, a plurality of guideposts disposed on the base plate; a plurality of springs disposed on the plurality of guideposts, a displacement transducer arranged to monitor a linear displacement of the first plate, and a controller, in communication with the load cell and the displacement transducer. The first plate is disposed to translate on the plurality of guideposts, and wherein the springs are disposed to urge movement of the first plate in relation to the base plate. The load cell is arranged to monitor a load exerted upon the base plate. The controller generates a signal that is based upon the load exerted upon the base plate or the linear displacement of the first plate in relation to the base plate.

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment and a swage machine. The pipe fitting includes a fitting jacket to be conformally deformed around tubing of the pipe segment. The swage machine includes a grab plate that interlocks with the pipe fitting, a die plate, in which a die is to be loaded in the die plate, a swaging actuator secured to the die plate, in which the swaging actuator facilitates conformally deforming the fitting jacket around the tubing of the pipe segment by causing the die plate and the grab plate of the swage machine to move toward one another, and a die retainer actuator secured to the grab plate of the swage machine, in which the die retainer actuator extends through the grab plate toward the die plate and pushes against the die.

A method of performing pressing on a workpiece using a press machine. The pressing method includes: performing pressing on the workpiece between a lower die and an upper die by causing the upper die to approach the lower die by using the hydraulic cylinder in a state in which the workpiece is disposed between the lower die and the upper die, and performing the pressing on the workpiece between the lower die and the upper die, in a state in which a shape of each of the frame, the lower die and the upper die has a rotationally symmetric shape about the reference axis and in which the workpiece center axis coincides with the reference axis.

A heavy-duty press is a mechanical machine used for compressing various parts and can be used for forging, molding, blanking, punching, deep drawing and many other applications. The force is generated by the use of hydraulic fluids based on Pascal's principle. The Press With Center Hole Hydraulic Cylinders simplifies the press design by using center hole hydraulic cylinders installed on the mobile platen with the press column inside the center hole. Center hole hydraulic cylinders being connected directly to the column eliminate the need of the third platen. A press with only two platens is cheaper and does not need large pits to be installed in. Also the design of the Press With Center Hole Hydraulic Cylinders use columns made of small section of hexagonal heat-treated steel bars arranged in an array forming a larger column of hexagonal shape. Columns made of small heat-treated bars are stronger, better connected to other press components and are much easier to fabricate and install.
