A kind of double action press
Technical field
The utility model relates to punching machine technical fields, more particularly to a kind of double action press.
Background technique
Punching machine is exactly a kind of punching type press machine, is mainly used for the production of plate type component.Pass through mold, presser
Skill can make blanking, punching, molding, drawing, finishing, fine, shaping, riveting and extrusion etc..Compared to traditional machinery
For processing technology, Sheet Metal Forming Technology saves material and the energy, high-efficient, not high to operator's technical requirements and pass through due to having
Various mold applications can make these advantages such as the impossible product of machining institute, keep its application field more and more wider
It is general, in the various aspects of national product.
The design principle of punching machine is that circular motion is converted to linear motion, is contributed by main motor, drive flywheel, through from
Clutch band moving gear, crankshaft, connecting rod etc. operate, and to reach the linear motion of sliding block, sliding block mating mold presses to material,
Make its plastic deformation, and obtains required shape and precision.In routine techniques, punching machine is typically only capable to completion one in a station
The processing of a process, such as the same station of workpiece need to be sheared, drawing multiple working procedure, then need successively complete by more punching machines
At or separate unit punching machine adjustment mold after complete several times, using trouble and efficiency is lower.
The Chinese patent of Publication No. CN206702030 discloses a kind of reverse double eccentric crankshaft punching machines, including crankshaft, the
One sliding block and the second sliding block, the crankshaft are successively arranged the first eccentric part and the second eccentric part, and first in its axial direction
