Further, said elbow-bar mechanism is a pair of, is symmetricly set on the slide block top.
Further; Be provided with governor motion between the undersetting of said slide block and elbow-bar mechanism; This governor motion comprises last movable voussoir, the following fixedly voussoir that the inclined-plane cooperatively interacts, and is fixed on the framework on the slide block, and the clamping screw and adjusting bolt in the framework stretched in the end that is threaded on the said framework; The end of said clamping screw props up movable voussoir, regulates the end and following fixedly voussoir threaded engagement of bolt.
Further; The syndeton of said side pressure system cylinder and frame is: comprise a cover plate; Drive locating hole behind the side pressure system cylinder on the cover plate, on the vertical gusset of said frame, have side pressure system cylinder prelocalization hole, the cylinder body front and back ends of said side pressure system cylinder is provided with the annular table terrace respectively; Clamp the front and back ends annular table terrace of side pressure system cylinder cylinder body by the vertical gusset of frame and cover plate respectively from the front and back ends of side pressure system cylinder, cover plate is connected fixing and locking side pressure system cylinder with frame through bolt.
The invention has the advantages that: during use, move the sight line compacting by hydraulic cylinder and side pressure system cylinder action drives patrix, left punch, the counterdie of right punch on workbench.Slide block drives elbow-bar mechanism by driving mechanism and realizes moving, and the slide block backhaul, descend speed fast soon, and speed of working stroke is slow and steady; And stamping press longer duration in the impulse stroke, compacting efficient is high, and the frame stressed effect is good; Reduce installed power, reduced production cost.
Elbow-bar mechanism is a pair of, and the slide block stressed effect is good, guarantees the compacting quality.Be provided with governor motion between the undersetting of slide block and elbow-bar mechanism, so that after connecting the middle bearing pin wearing and tearing of upper and lower toggle link in the elbow-bar mechanism, carry out the adjustment of slide position, can normal smoothly no gap matched moulds when making compacting.
Side pressure system oil cylinder is fixedly clamped through the vertical gusset of cover plate and frame, is difficult for causing the fracture of bolt during use, improves bolt service life greatly.
