Abstract

The utility model provides a puncher punches a hole and actuates improvement of mechanism is that the noose has a capping piece in the pivot of blade holder holds the hole, through the pressure arm pressurized deflects and forces the cutter produces when punching a hole the action, makes the interlock pivotal axis jack -post face forms the level contact and the displacement of axis and terminal surface on the interior periphery face of capping piece, can avoid that the jack -post face of pivotal axis is direct in the pivot of blade holder holds the hole to produce the wearing and tearing phenomenon that the axle moved with the contact dististyle, promotes stability and the life of puncher in the action of punching a hole.

Description

The improvement of puncher punching actuation mechanism

Technical field

The utility model relates to a kind of actuation mechanism of paper punching office accommodation, particularly a kind of improvement of puncher punching actuation mechanism.

Background technology

Refer to shown in Fig. 7 to Figure 11, conventional puncher roughly includes a bearing 1, two to be incorporated into respectively in described bearing 1 and to have the tool rest 2 in two start holes 21, two to stretch through respectively between described tool rest 2 and described bearing 1 and can be tied by pivot the cutter 3 carrying out reciprocating type displacement in described start hole 21, one to tie with described tool rest 2 and described cutter 3 pivot and can the pressure arm 4 of cutter 3 punching start described in interlock, and two are located in respectively between described tool rest 2 and described pressure arm 4 and provide described pressure arm 4 spring element that start is replied 5 according to this.

When above-mentioned puncher pressure arm 4 be used as power be delivered to paper punching time, because described pressure arm 4 is linked with described cutter 3 respectively by two action shafts 22, and be subject to the stroke restriction in described start hole 21, the upper and lower displacement that therefore described cutter 3 only can be vertical in described start hole 22; And the fulcrum pivotal axis 23 that described pressure arm 4 links with described tool rest 2, hold lateral displacement start in hole 24 in the pivotable of described tool rest 2 strip, after described in described pressure arm 4 interlock, cutter 3 pairs of paper complete punching operation, described pressure arm 4 can be returned back to initial inactive state by described spring element 5.

But, described puncher is used for the cutter 3 of punching, and to be through described action shaft 22 interconnected with described pressure arm 4, and described pressure arm 4 itself is be provided with the hole position (not shown) corresponding with described fulcrum pivotal axis 23, so described punching spatially can be produced the phenomenon of skew by initial inactive state, be in fact exactly because be incorporated in the pivotable appearance hole 24 of described tool rest 2 in described fulcrum pivotal axis 23.

From explanation above, when the stressed deflection start punching of described pressure arm 4, described cutter 3, therefore only can displacement vertically downward in described start hole 21 because being subject to the consolidation restriction of its stroke of described start hole 21;

Relative, the fulcrum pivotal axis 23 fixedly connected with above-mentioned pressure arm 4, solid owing to being subject to described pressure arm 4

If distance restriction, that is, described in described fulcrum pivotal axis 23, the drag distance of action shaft 22 is under remaining unchanged, described fulcrum pivotal axis 23 only can hold in the pivotable of the strip of described tool rest 2 lateral displacement making fraction in hole 24, and move in displacement at the axle of long-term pressurized, described fulcrum pivotal axis 23 is direct start on the contact site in described pivotable appearance hole 24 and produces the dynamic wearing and tearing of axle, causes described pivotable appearance hole 24 to produce the phenomenon of reaming gradually;

When after the long-term start of puncher, the eroded area 25 that above-mentioned reaming phenomenon is formed will expand gradually, then described fulcrum pivotal axis 23 will to top offset at the start length of support that described pivotable is held in 24 holes, this kind makes the displacement deviation of activity supporting point, by cause cutter 3 cannot punching to the stroke of described bearing 1 bottom, and then affect the through of overall paper punching, what is more, will the service life of puncher be lowered.

Summary of the invention

The purpose of this utility model is the improvement being to provide a kind of puncher punching actuation mechanism, that a kind of jack-post face of pivotal axis and contact dististyle of tool rest avoided produces wear phenomenon, can the stability of lifting, punching machine punching start and service life, particularly a kind of improvement of puncher punching actuation mechanism.

For this reason, the utility model proposes a kind of improvement of puncher punching actuation mechanism, it includes: a bearing, is a platform pedestal; Two tool rests, be incorporated in described bearing respectively, each tool rest has relative start hole, two intervals, and each tool rest be provided with one can overlap have a groove cover plate pivotable hold hole, described groove cover plate is formed with the inner peripheral edge surfaces lamellar body of the horizontal end face of a tool, holds between hole to be installed with a pivotal axis in described groove cover plate inner peripheral edge surfaces and described pivotable; Two cutters stretch through respectively between described tool rest and described bearing, and can be stretched through pivot knot by an action shaft, and carries out shuttle displacement in the start hole of described tool rest; One pressure arm ties with described tool rest and described cutter pivot, and can cutter described in interlock in order to paper punching operation; And two spring elements, be located between described tool rest and described pressure arm respectively, the start restoring force of described pressure arm is provided thus, when making the deflection of described pressure arm pressurized force described cutter to produce punching start, will form flat contact and the displacement of an axis and an end face in the jack-post face of pivotal axis in the inner peripheral edge surfaces of described groove cover plate described in interlock, the contact dististyle avoiding the jack-post face of described pivotal axis and described tool rest pivotable to hold hole thus produces the dynamic abrasive conditions of axle.

Described pivotal axis cording has a jack-post face, and the start of described jack-post face system is in the inner peripheral edge surfaces terminating in described groove cover plate.

Described spring element one end is provided with a combined hole, described spring element and described tool rest is linked in the lump in described bearing in order to do for a conjunction.

The described spring element other end is provided with and can be used for cutter described in support and support stop section only with action shaft.

Described pressure arm is provided with itself can the pivot hole tied of pivot corresponding to described pivotal axis.

By learning above, the utility model is compared to prior art, be that the pivotable of described tool rest is held in hole to be firmly arranged with a groove cover plate, when forcing described cutter to produce punching start by described pressure arm pressurized deflection, make pivotal axis jack-post face described in interlock in the inner peripheral edge surfaces of groove cover plate, form flat contact and the displacement of axis and end face, can avoid the jack-post face of pivotal axis in the pivotable of tool rest to hold in hole directly with contact dististyle and produce the wear phenomenon that axle moves, thus the stability of lifting, punching machine in punching start and service life.
