Description

Connecting rod device for high precision press

Technical Field

The utility model belongs to the technical field of connecting rod devices, in particular to a connecting rod device for a high-precision press.

Background Art

A press (including punching machines and hydraulic presses) is a general-purpose press with an exquisite structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. The metal blank is processed into parts by applying strong pressure to the metal to cause plastic deformation and fracture. When the mechanical press is working, the motor drives the large pulley (usually also serving as a flywheel) through the V-belt, and drives the crank slider mechanism through the gear pair and clutch, so that the slider and the punch go down in a straight line. After the forging work of the mechanical press is completed, the slider moves upward, the clutch automatically disengages, and the automatic device on the crank shaft is turned on, so that the slider stops near the top dead center.

Presses are widely used, and some conventional large pressing machines also belong to the category of presses. They hammer the workpieces continuously for many times to make them into the required state. However, this working state requires manual adjustment of the position of the workpiece to cooperate with the pressing, which is not convenient enough.
