A kind of Shears for thin sheets cutting apparatus

Technical field

The utility model relates to a kind of shear, specifically refers to a kind of Shears for thin sheets cutting apparatus that can be used with motor drive mechanism.

Background technology

The thin plate clipper is as the indispensable instrument of mechanical processing industry, it uses frequent and extensive, and the Shears for thin sheets cutting apparatus that cooperates motor drive mechanism to use can directly be engaged in because of it and uses on power take-off mechanism such as electric drill, do not need the optional equipment motor, and manoeuvrable, cutter is joined and is changed conveniently, thereby is subjected to practitioner's favor, for this reason, people have made multiple research or improvement to the Shears for thin sheets cutting apparatus.For example the patent No. is 96225519 the disclosed electric drill driving of Chinese utility model patent plate-shears, it includes housing, handle, eccentric shaft, slide block, slide block set, sliding shaft rod, Upper shaft sleeve, Lower shaft sleeve and knife bar, lower part of frame is provided with support, the broach shell that is connected on the support, knife bar is attached at the lower end of sliding shaft rod by connector.During use, the outer end of eccentric shaft is installed on the chuck of electric drill, eccentric shaft and slide block drive slide block set and up and down reciprocatingly slide, thereby make the sliding shaft rod of fixedlying connected with slide block set drive the knife bar motion, thereby finish the cutting action.This utility model adopts electric drill to drive, and is easy to operate, and split is connected with cutter owing to knife bar, so cutter changing is convenient, and is easy to carry about with one.But this plate-shears only has a blade, relatively is fit to carry out the cutting of the cutting form of soft material, and is not suitable for for the hardboard that requires to shear; And these utility model parts are many, complex structure.

Summary of the invention

Technical problem to be solved in the utility model is the situation at prior art, provides a kind of simple and reasonable, is fit to carry out the Shears for thin sheets cutting apparatus that iron plate is sheared.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of Shears for thin sheets cutting apparatus, comprise housing, cutter, bottom knife and eccentric shaft, it is characterized in that: the tool bore that described housing front end is provided with and keeps supplying, the blade of bottom knife passes, its inside has cutter shaft, and the rear end has the axis hole that passes for eccentric shaft; The middle part of cutter and bottom knife is respectively equipped with upper and lower cutter shaft hole suitablely, the following cutter shaft hole of bottom knife is passed cutter shaft and is fixed in the housing, the upper slitter axis hole of cutter passes the cutter shaft axle and is fixed in the housing, the front axle that eccentric shaft has eccentric block is fixed in the housing, eccentric block is against the afterbody of cutter, and the rear portion of eccentric shaft passes axis hole and exposes outside the housing.

Installation and removal for convenience, housing preferably includes base and loam cake, cutter shaft is located at the front portion of base, the rear portion of base and loam cake have match and with the suitable axis hole of eccentric shaft; Loam cake and base are fixed together by screw bolt and nut.

Cover on described and also be provided with and the suitable screw hole in the position of cutter shaft, cutter spindle sleeve places the top of blade and is enclosed within on the cutter shaft, and screw DRIVE SCREWS hole is against on the cutter spindle sleeve.Screw hole and screw mating reaction can be regulated the gap between the upper and lower blade, with convenient iron plate of shearing different-thickness; Simultaneously,, after upper and lower blade is loosening because of shear action, can regulate easily, prolong the service life of blade by the cooperation of screw hole and screw.

More stably work in order to make this Shears for thin sheets cutting apparatus, the afterbody of described cutter can be designed to have the breach of " M " shape, the diameter of its width and eccentric block is suitable, cutter can accurately be worked under eccentric block ground drives like this, eccentric block is against on the protrusion at " M " v notch v middle part, makes that the butt of eccentric shaft and cutter is firm, strong.

Preferably be with the excentric sleeve that makes things convenient for the eccentric shaft location and fix on the described eccentric shaft, the axis hole at housing rear portion is and eccentric shaft and suitable " protruding " font of excentric sleeve; The use of excentric sleeve makes that the rotation of eccentric shaft is more flexible, has reduced the wearing and tearing of eccentric shaft simultaneously.

In order to make bottom knife fixing better, can on described base, establish a fixed axis, offer fixed shaft hole on the bottom knife suitablely, the height of fixed axis is identical with the thickness of bottom knife.

Described lower housing portion preferably is provided with the handle of a handled easily, when using this Shears for thin sheets cutting apparatus, can more accurately control the action of scissors like this.

Compared with prior art, the utility model is simple in structure, is used with power take-off mechanism such as electric drill, is particularly suitable for the shearing of iron plate, and flexible and convenient operation, and cutter changing is convenient; Especially cover the screw hole offered and the cooperation of screw on, can regulate the gap between the upper and lower blade more easily, not only expanded the scope of application of this Shears for thin sheets cutting apparatus, and prolonged the service life of blade.
