The operating principle of precision punching machine is that in the operation of precision punching machine, the automatic precision punching machine circuit receives the solid table press through two lifting oil cylinder mold support plates. The support plate specified by the die-casting mold is installed in the mold, and the punching machine manufacturer's mold is fixed on the upper module of the paper. The high-speed punching machine continuously moves to the left at a certain speed from left to right or right to the mold head.
The precision punching machine drives the pulley through an electric motor, which drives the belt to drive the pulley to rotate passively and actively, thereby driving the active crankshaft pulley. The crankshaft driven by the reverse rotation of the crankshaft gear drives the active stamping, and the active power of the crankshaft and crankshaft is driven by synchronous motion with the drive of four sets of crank connecting rods when rotating in reverse at the same speed. The shaft of the four connecting rods 2 is connected by the lower end of the sliding device, and the reciprocating up and down sliding punch driven by the reciprocating motion of the four connecting rods at the lower end is driven by the relative motion of the punching sheet material between the upper and lower molds and molds.
The precision punch presses the elastic plate at a speed fixed to one end of the body, while the other end is fixed to the sliding device. The precision punch uses the method of restricting the sliding component along the direction of motion. The displacement direction of the left sliding rod further refers to the movement without restriction in the vertical direction, while the movement direction of the rear sliding component refers to the front cover being set. In the curve limited by four rollers, but the curve of the roller and the wheel side of the sliding component relative to the rolling device, the movement of sliding along the vertical direction is not restricted. By moving up and down in the vertical direction on the elastic plate and the curved roller, and the combined effect of the four high-speed punch slider devices to be connected, and the accurate positioning of the lower mold, the positioning accuracy can reach more than 0.01. mm.
