Punching machine

Abstract

The invention relates to a punching machine, which belongs to the technical field of mechanical presses. The punching machine includes a machine frame, a guide pillar and integrated production device.The integrated production device includes a machine base which is fixed on the machine base, a bed plate installed with molds and a pushing bar. The bed plate is installed under the machine base andis arranged on the guide pillar. The bed plate can move upward and downward along the guide pillar. Half cylinder push blocks are installed between the machine base and the bed plate. At least two groups of linkages are installed on half cylinder push blocks facing directly to each other. The half cylinder push blocks are fixed on the pushing bar, capable of repeatedly moving between the machine base and the bed plate. Arc chutes are installed on the half cylinder push blocks along the circumferential extension of the centerline. Every group of linkage includes a upper connection bar, a lowerconnection bar, a working bar and a pin roll. The punching machine is simple in structure and novel in transferring method. The novel transferring method enables transferring ability to enlarge several times, resulting in the effective reduction of energy consumption. The punching machine has a compact structure, a small volume and has the advantages of reducing shock vibration and shock noise.

Description

technical field [0001] The invention relates to a stamping machine, which belongs to the technical field of press operation. Background technique [0002] The devices currently used in the market for stamping, stretching and extrusion production, such as those used in hydraulic sheet blanking machines, are mechanical blanking machines driven by motors that drive pulleys, pulleys that drive gears to rotate, and gears that drive crank mechanisms. When it is working, not only the impact vibration and impact noise are large, but also the power consumption is high. [0003] The patent number applied by the inventor is ZL201120326594.7, and the name of the invention is a Chinese patent of a hydraulic sheet blanking machine. The lower end of the toggle lever is hinged at the corner of the toggle lever, and the lower end of the toggle lever is hinged on the flat lower support on the machine base plate. One end of the short connecting rod of the toggle booster mechanism is hinged to...
