Hi, how can I help?
The fuselage is made of three parts:the bed, base and worktable,the subplate on the worktable is used to install chess. The fuselage is mostly cast iron material, while the large press machine is made of steel plate welding. First, the fuselage need to meet the rigidity and strength conditions, conductive to vibration and noise reduction,guaranteed the press stability.
The operating mechanism is a crank-link mechanism consists of crankshaft, connecting rod and slider. The crankshaft is the most important part of the press, and its strength determines the punching capacity of the press; the connecting rod is a connecting member, and its both ends are connected with the crankshaft and slider; the slider with the upper die is the executive element, and finally,to complete the punching action. The input power rotates through the crankshaft, drives the connecting rod to swing up and down, and converts the rotating motion into the reciprocating linear motion of the slider along the guide rail fixed on the fuselage.
Crankshaft adopts fine copper material, wearproof, long life.
Mould installation, simple and convenient.
Maintain convenient and stability, mould height adjustment.
Bimanualness, inching, interlock.Safety and realiable.
Pedal brake, operation simply.
Adopts Schneider electric appliance, long life.
The power transmission system composed of a motor, a transmission device (gear drive or belt drive) and a flywheel, in which the motor and flywheel are power components. In the empty stroke of the press, the kinetic energy is accumulated by the moment of inertia of the flywheel itself; when the moment force of the punching workpiece is maximum, the flywheel releases the accumulated energy, which makes the load of the motor is balanced, the energy utilization is reasonable and the vibration is reduced. Some punching machines use big gear or belt wheel to achieve the function of flywheel.
