Abstract

The utility model discloses a span-hole number adjustable punching mechanism, belonging to paper punching machinery. The punching mechanism is provided with identical rail through holes or through slots respectively on the rear part of the die body of each arch-shaped hole, and the through hole or the through slot are penetrated by a rail of which back is provided with equidistant location holes which can be locked through a spring pin. A base board is provided with a paper scrap outlet of which span and quantity are corresponding to that of the rail location hole; an eccentric cylinder compression bar hinged with a handle shank is pressed to be contacted with the cambered surface of the tip of a spherical surface vertical to the cutting tool to cause the cutting tool to be lifted. The punching mechanism designed in this way, realizes that the hole number and the hole span can be optionally adjusted according to needs and meet the binding requirement.

Description

The adjustable perforating mechanism of spacing hole count

The utility model relates to paper punching machinery, the adjustable perforating mechanism of particularly a kind of spacing hole count.

Must first eleven punch 11 or punching before the paper spare data bookbinding, common commercially available card punch no matter single hole, diplopore, porous all is structure as a whole, and whether the pitch-row method of adjustment of porous card punch is to utilize the punching cutter of fixed position and spacing to descend and determine hole count and spacing.Be that hole count and spacing become integral multiple increase and decrease, and can not arbitrarily adjust as required, and cutter descends and also mostly is directly to exert pressure or is the lever emphasis with the cutter top that arm of force pressurization is finished.

The purpose of this utility model is exactly to contact the random adjustable perforating mechanism of the pitch-row hole count that presses down cutter in order to provide a kind of with eccentric garden cambered surface, and therefore, the utility model is had any different in prior art.

The utility model designs by following technical scheme.

But the support body that surrounds by plate behind the base plate side plate, pressure handle handle, bow type casement body and go up cutter through the spring-loaded vertical lift, the bow type casement body rear portion that each structure is identical has identical guide rail through hole or guide rail groove, and run through by cross slide way, the guide rail dorsal part is provided with the equidistant locating hole through spring pin locking bow type casement body.

During use,, the bow type casement body of corresponding number is installed on guide rail according to the hole count needs, according to the pitch-row requirement, with spring pin bow type casement body is locked on the locating hole of corresponding spacing position, pushes the pressure handle handle cutter is vertically descended, can will give the paper spare punching that is contained in casement mouth place.

She Ji adjustable perforating mechanism moves, increases and decreases bow type casement body like this, realizes that promptly hole count can increase and decrease as required, and pitch-row is arbitrarily adjustable, has satisfied the binding parts requirement.

Below in conjunction with drawings and Examples it is described the utility model.

Fig. 1 is the utility model assembly structure front-view schematic diagram.

Fig. 2 is the utility model guide rail schematic rear view.

Fig. 3 is the utility model bow type casement body guide rail groove vertical profile schematic side view.

1, pressure handle handle, 2, eccentric garden post depression bar, 3, side plate, 4, base plate, 5, bow type casement body, 6, cutter, 7, spring, 8, square rail, 9, circular guideway, 10, rectangular guideway and base plate right angle integrated section, 11, spring pin, 12, locating hole, 13, the technology connecting hole, 14, paper scrap portals, and 15, screw.

The adjustable perforating mechanism of spacing hole count through base plate, side plate, after the support body that surrounds of plate by screw and technology connecting hole assembling one.

Base plate up-bow type casement body spring-loaded cutter, the guide rail two ends are spirally connected through screw and side plate.

Shaped as frame pressure handle handle two ends are through the hinged eccentric cylinder depression bar of side plate two ends, and eccentric cylinder contacts as cambered surface with cutter sphere termination arranged side by side, makes the cutter lifting.

The guide rail through hole side-looking at each bow type casement body rear portion can be identical circular port or square opening or swallow-tail form hole etc., and with its in section should be guide rail circular or square or swallow-tail form mutually and be slidingly matched.

The guide rail groove notch at each bow type casement body rear portion is downward.

The rectangular guideway and the base plate at bow type casement body rear portion are the right angle integrated section.

The position of guide rail locating hole, spacing and quantity are corresponding with position, spacing and quantity that the base plate paper scrap portals.

According to the hole count needs, can give on the guide rail of this perforating mechanism and adorn 3,5,6,8,10,12 or more a plurality of independent bow type casement body.

Claims
