The portable mechanism puncher

Technical field

The utility model belongs to small-sized electric power tool, is specifically related to a kind of portable mechanical punching facility.

Background technology

Portable mechanical punching machine is mainly used in department's circuit distribution cross-arms such as electric power, telecommunications, railway, the punching of iron tower of power transmission line tower material, repaiies hole, reaming, the copper bar of converting equipment, aluminium row's punching and device clamp, band steel perforate etc.Existing portable mechanism puncher has two kinds of hand-hydraulic perforating press and hand mechanical drilling machines.The hand-hydraulic perforating press is made up of compression system and drift punch die, and workpiece is fixed on the perforating press, and the drift punch die is sheared punching to workpiece under the pressure effect of compression system, changes the drift punch die and can change punching hole diameter.This perforating press disposes hydraulic system because of needs, and its structure is not only comparatively complicated, and weight is big, the about 20-22Kg of unit weight, and carrying and operation are all inconvenient.Hand mechanical drilling machine is made up of frame and hand drill holes mechanism, though this drilling machine is relatively simple for structure, unit weight is 9.5Kg only, but this puncher is owing to be to be that power is holed on workpiece with the manpower, therefore deposit following deficiency: the operational forces during 1. because of boring is a revolving force, so the operation complete machine is fixing difficult in the open air; 2. inefficiency generally bored a hole in 5-6 minute; 3. labour intensity is big, and the hand power of pulling when general hand mechanical puncher is worked is 300-400N.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, propose a kind of simple in structure, unit weight is little, fireballing portable mechanism puncher punches.

The technical scheme that realizes above-mentioned purpose is: the portable mechanism puncher, it includes two support arm-tie, two identical yoke plates, a pressure head plate, a die head and one group of die-punch that shape is identical.The shape approximation of described support arm-tie respectively has a through hole perpendicular to the plate face in an obtuse triangle on three angles; The shape approximation of described pressure head plate is in a U-shaped plate, and the two ends of pressure head plate respectively has a through hole perpendicular to the plate face; There is a boss upper end of described die head, and interposition is equipped with a horizontal breach, and being positioned at this horizontal breach one side has a vertical top through hole and lower thread hole.Two support arm-ties separately the through hole by the position, obtuse angle with its below an end of yoke plate hinged, the through hole of an end is hinged on the other end of yoke plate and the pressure head plate; The pressure head plate is fixed on the boss of die head; The drift of described die-punch set is installed on the briquetting, the both sides of described briquetting respectively with two the support arm-ties an acute angle on through hole hinged, punch die is fixed in the screwed hole of die head; The upper end of two support arm-ties is connected with leading screw with screw by the screw in the through hole separately respectively, and there is a ratchet leading screw centre, has interlocked a ratchet wrench frame assembly on the ratchet.

During the work of the utility model portable mechanism puncher, the position of workpiece desire punching is positioned in the horizontal breach of die head, the rocking arm of the moving ratchet wrench frame assembly of plate, leading screw rotates, and drive two the support arm-ties close up in opposite directions, drift is moving downward in the through hole at die head under the effect of briquetting, can finish the shearing punching to workpiece.

As a kind of improvement technology of the utility model, at an end of leading screw a rocking arm is installed, rotate rocking arm and can make the leading screw quick rotation, realize the quickly opening and closing of support arm-tie.

The utility model portable mechanism puncher punching speed is fast, can dash a hole in general 1 minute, and compared with prior art efficient can improve 5-6 doubly, and the hand power of pulling during work only is 150-200N.In addition, the replaceable drift of the utility model can not only be towards circular hole, and can be towards square hole.
