Pillows
When the actuator is used for drawing operations, the way in which the low holding pressure is used to control the flow of the low metal is important. Applying pressure to the low holding position is one of the functions of the double-acting presses. Single-acting presses lack this function and therefore require extra low-holding equipment. Molds sometimes constructed using a low holder with compression springs, air cylinders, or high pressure nitrogen cylinders to provide holding pressure. This will greatly increase the cost of the matrix. The presses pad meets this requirement, which reduces tool costs. NC Shearing Machine
Pneumatic pillows
The pneumatic punch is supplied with workshop air pressure. The design usually uses one or two pistons and cylinders. The recommended capacity of the cushion is about 15-20% of the nominal tonnage of the presses. The size of the press bed opening limits the size, type, and capacity of the cushion.
Upgrade of existing presses
Older presses are candidates for modernization for smoother, more reliable operation and lower tool wear. In some cases, rebuilding a damaged press can pay off quickly in reducing tool repair costs and improving part quality.
Electrical controls
Electrical controls that may no longer meet safety requirements may be replaced. Often the most satisfactory way to recreate a press is to install a new control package specifically designed for the application. Such systems are available from many suppliers.
power press
A power press is a machine that supplies energy to a die used in forming, shaping or forming metal as a non-metallic material. Therefore, the machine press is part of a manufacturing system that combines a press, a die, a material, and a method of feeding to produce a part. The press consists of a frame, a bed or a support plate and a reciprocating member called a ram or slide, which forces the material to work with special tools attached to the frame and the bed. The energy accumulated by the rotating flywheel by the mechanical press transfer to the ram to ensure linear movement. The system designer shall determine suitable operating point guards to protect the press staff.
Hydraulic forming machines and dies
The process uses a thick rubber pad that is located inside the press frame. The die is located on the lower press plates or bed. This process has long use to create short segments of thin soft materials such as aluminum. Many processes apply hydraulic pressure to the workpiece through a flexible rubber diaphragm or membrane. These systems combine many of the benefits of direct noise-free fluid use. The forming process uses the method of applying direct hydraulic pressure to a rubber forming pad. Semi-finish products, similar to those use in Guerin’s process placed on ordinary men who died.
Hydraulic forming machine. The shores and the dead transfer to the press frame of the carrier. The build-up of pressure apply by hydraulically inflating a rubber bag onto the stationary roof of the press.
