Description
Technical field
The utility model relates to small-sized hydraulic paper cutter accessory device, particularly foot-operated prepressing device.
Background technology
Along with the ripe and development of hydraulic technique, the output of small-sized hydraulic paper cutter increases fast.The paper-pressing mechanism of existing small-sized hydraulic paper cutter adopts double-action hydraulic press structure and single-acting hydraulic mechanism, and the former resets for hydraulic pressure platen and hydraulic pressure, and the latter is hydraulic pressure platen and spring reset; And two class paper-pressing mechanisms all do not have pre-platen function.In the paper cutting process, for guaranteeing accurately to cut, often need carry out trace adjustment to the position that cuts, pre-platen is the needs that are fit to the trace adjustment; Because described paper-pressing mechanism does not have pre-platen function, thus many inconvenience brought to the operator, thus influence operating efficiency and cut quality.
Existing floor push mode realizes pre-platen function, and its principle is to switch ultralow pressure oil circuit (oil pressure is below 0.1MPa) fast at pre-platen time control system magnetic valve.Because paper cutter is the very high equipment of a kind of operational danger, simple hydraulic system is kept oil pressure at 0.1MPa ultralow pressure poor stability, the fluctuation of oil pressure, and the speed of magnetic valve switching time all directly has influence on operator's personal safety.
Summary of the invention
The utility model will solve existing small-sized hydraulic paper cutter paper-pressing mechanism not to be had pre-platen function and causes inconvenient operation, and influence operating efficiency and cut the problem of quality; And the existing problem that can differ from by the pre-platen functional safety of control magnetic valve realization.Provide a kind of small-sized hydraulic paper cutter of the present utility model to ride mechanical prepressing device, this prepressing device is simple in structure, and is easy to operate, high safety for this reason.
For addressing the above problem, the technical solution adopted in the utility model is to be connected with two swing arms of stretching down to support on main working plate, two swing arms are supported upward, and each pivot is connected with swing arm, inner each pivot of two swing arms is connected with connecting plate, two connecting plates upper end span is associated with jacking block on the oil cylinder, two swing arm outer ends respectively are connected with extension spring, the extension spring upper end is connected in main working plate, place and be connected with the gallows pull bar on the gallows between the gallows guide plate, the outer end pivot of gallows pull bar lower end and described swing arm connects, its special character is that a swing arm outer end is connected with down the foot-operated pull bar of stretching, and foot-operated pull bar lower end is connected with foot-driven lever, and jacking block and oil cylinder piston masthead end break away from the described oil cylinder.
Should be provided with the pull bar adjustment seat at foot-operated pull bar and foot-driven lever junction, foot-operated pull bar is connected with foot-driven lever after the cylinder lever connecting rod adjustment seat.
Should on the left and right riser at place, gallows two ends, respectively be provided with the up spacing adjustment screw of gallows,, guarantee that cutting knife does not expose gallows, improve processing safety with accurate adjusting gallows upper limit position.
The utility model is owing to be connected with the foot-operated pull bar of stretching down in a swing arm outer end, and foot-operated pull bar lower end is connected with foot-driven lever, so only need depress foot-driven lever, the foot-operated pull bar of pulling is descending, just can make the swing arm outer end bottom, thereby overcome tension spring tension, the pulling gallows is descending, realizes foot-operated pre-platen; The utility model is owing to jacking block on the oil cylinder and the disengaging of oil cylinder piston masthead end, and the pressure of the foot-operated precompressed of old friend worker is little and laborsaving; The utility model adopts the mechanical system of foot-driven lever to realize pre-platen function, and preload pressure, squeeze time are controlled flexibly by the operator, and man-machine conformability is good, and is easy to operate, the security performance height; Preload pressure can conveniently be regulated by the utility model that the pull bar adjustment seat is connected with foot-driven lever in foot-operated pull bar lower end; Left and right riser is provided with the utility model of the up spacing adjustment screw of gallows, can accurately adjust the gallows upper limit position, guarantees processing safety.
