Toggle link, the lower elbow lever are hinged on sliding block, and described upper elbow lever one end is hinged on connecting rod, and the other end of upper elbow lever is hingedly expert at
On journey regulating mechanism, the stroke control mechanism includes the mandrel being mounted on fuselage, and being set on the mandrel can be along mandrel
Movable block in axial sliding is equipped with the retaining mechanism that can be locked at movable block on mandrel on the movable block.
When the invention works, movable block is locked on mandrel by retaining mechanism, it is avoided to move axially along mandrel, when
When needing to adjust stroke, retaining mechanism only need to be unclamped, is adjusted at the top of upper elbow lever by adjusting position of the movable block on mandrel
Fixed position is formed after the completion of adjusting, then lock retaining mechanism to complete the adjusting to stroke, can normal use pressure
Machine.Compared with prior art, the beneficial effects of the present invention are the present invention is realized by adjusting position of the movable block on mandrel
The adjusting of the stroke of a press, and lock mechanism and guarantee the stable operation of press machine, the configuration of the present invention is simple, stroke adjustment is just
Victory, during the present invention can be used for knuckle-lever press stamping products.
As a further improvement of the present invention, screw rod is provided through on the fuselage, the screw rod protrudes into the one of fuselage
End is connected on movable block, can be convenient sliding motion block.
As a further improvement of the present invention, one end that the screw rod protrudes into fuselage is fixedly connected with jacking block, the jacking block
It is connected on movable block, the stress surface of movable block can be further increased, so that push-and-pull effect is more preferable.
Institute as a further improvement of the present invention, stating retaining mechanism includes locating rod, is fixed on fuselage at the top of locating rod
On, the axis hole equal with positioning shank diameter is offered on the movable block, offers multiple stroke location holes, institute on the mandrel
The bottom insertion stroke location hole for stating locating rod, can be convenient the adjusting of stroke, realizes that multiple-pass is adjusted, improve degree of regulation.
As a further improvement of the present invention, first boss, first boss periphery set are processed at the top of the locating rod
Equipped with the pressing plate that locating rod is pressed on to stroke positioning hole, the pressing plate is fixed on fuselage through screw, so that locating rod exists
More secure under locking state.
As a further improvement of the present invention, second boss is processed into the first boss, the periphery of second boss adds
Work has screw thread, and locking nut is threaded in second boss, can be further improved the peace of locating rod in the locked condition
Full property and fastness.
