Types of Press Machines
Press machine is a machine that was created to make sheet metal, bending sheet metal with the desired angle shape. Press machines have 3 main parts namely the frame, ram and bed. The mechanical system of this machine works to drive the ram, then proceed to the press dies and push the sheet metal so that it can be formed and cut into the function of the press dies used. In general, press machines consist of 3 types of power namely manual, hydraulic and mechanical.
- Press Manual
This machine still relies on human power. Manual press machine has a steering wheel that can be driven by the operator to be able to raise and lower the piston. If you want to reduce the piston, then turn the steering wheel to the right, while to increase the piston turn the steering wheel to the left. Because it is manual, the use of this machine is still relatively inexpensive and inexpensive. However, this machine can only be applied to thin iron plates with a minimum thickness of 1mm to 2mm.
2. Hydraulic Press
Unlike the type of manual, the type of hydraulic press is a machine that works relies on pascal legal theory that is utilizing the pressure applied to a special fluid to be able to press the plate. This machine has several components namely piston, cylinder, hydraulic pipe and others. In terms of durability, you could say this machine has a better power endurance system than an electric powered engine. The level of accuracy is also quite controlled, and the maintenance process is so easy.
3. Mechanical Press
Mechanical types rely on the fly wheel system or are driven by an electro motor, then proceed to the crank shaft and slide up and down. Then to control the position utilizing a clutch and break system that relies on pneumatic power. The pneumatic system is used as a balancer and die cushion. For in Indonesia, mechanical press machines still rely on compressive strength only reaching 2500 tons.
