Pole punch tool for forging the actual name of presses, mechanical and hydraulic generally divided into two categories, but recently there is a new form of liquid pressurized punch. Mechanical Presses is a traditional form of organization structure for the crank and connecting rod, crankshaft eccentric to promote the use of the slider up and down movement, reaching stamping purposes. Hydraulic presses is to promote high-pressure oil pump produces hydraulic cylinder action, which led to stamping slider moves to stress. Pressurized hydraulic liquid is basically the same, but he pushed the power source is compressed air, the use of air into the hydraulic pressure. Mainly aimed at stamping punch plate. Mechanical and hydraulic punch punch more pressure on the object based on a certain pressure, the pressure is the use of punch with mold on the metal parts processing, its bending deformation, tailoring. General machining is called molding, stretching, blanking, punching. Able to live mold, do Chula cutting, punching, forming, deep drawing, trimming, fine blanking, riveting and extruded parts, etc., are widely used in various fields. If we use the switches and sockets, cups, cupboards, dishes, computer case ...... there are very many accessories can be produced through a die with a punch. Use these processing functions to achieve the kind of sheet metal parts processing. Sheet Metal parts, for example, security doors various electrical cabinet and so on.
