punch press machine that changes the size or shape of a piece of material, usually sheet metal, by applying pressure to a die in which the workpiece is held. The form and construction of the die determine the shape produced on the workpiece.
A punch press has two coacting components: the punch, which is attached to the reciprocating ram of the machine, and the die, which is clamped onto a bed or anvil whose flat surface is perpendicular to the path of the ram. In operation, the punch pushes against the workpiece, which is held in the die. A blanking die shears out a slug of sheet metal to make it into a blank that will fit dies for subsequent punch-press operations.
These include forming or bending and drawing, in which cup-shaped articles are produced by a process that entails some plastic flow of the metal.
1. Before starting, check parts of press manipulation, clutch and brakes are active, the security guard is complete and easy to use, whether ministries crank exception. If abnormal, should immediately take the necessary measures 2. Before formal operating subject to idle test, be sure each part can normal work. 3. The operation must use the tools, is prohibited by hand directly into his mouth extract die, hand tool should not be putted on the mold. 4. Foot must be far away from the foot pedals, when adjust or get the workpiece in mould area. 5. Sudden power off or operate finished, we should close the power, and restored to the clutch in neutral gear manipulator, brake in braking. 6. On the press for maintenance, adjustment and installation, adjustment, dismantling the mold should be disconnected the machine energy (such as electricity, gas, liquid). Putting warning notice on the startup switches.
