Abstract

The utility model relates to a multifunctional hand pressure shearing machine which is composed of a body, upper and bottom blades, a lever head, a toggle rod, a swaging support, swaging screw bolts, a torsion spring, a handle, a lever head half axle, and an upper blade half axle. The body is a twist-shaped one chip structure. The upper blade is a double edge symmetric body so that the service life is prolonged by one time. Both ends of the bottom blade is an acute angle longitudinal section so that steel plates can be clipped and flat steels, round steels and angle steels including oblique angles and breaches of angle steels can be cut off. The utility model has the advantages of multiple functions, large force of cutting, convenient operation, labour saving, simple structure, and light weight. The utility model is a novel of product of manual shearing equipment.

Description

Multi-functional cutting machine

A kind of multi-functional hand cutter is the manual shearing equipment in the mechanical engineering, is mainly used in to the cutting blanking of steel board and for the shearing operation of band steel, round steel, angle steel.

The manual shearing equipment that uses in producing now, kind is more, mostly be eccentric slider type on the structure, except having body, cutter, lever head, bottom knife only is fixed in following of body for square bar shaped bloom, can't shear the oblique angle and the breach of angle steel, cutter is the single-blade structure, low and the lever head of valuable steel utilization ratio adopts gear to be connected with bindiny mechanism between the blade, thereby force increasing ratio is little, shear effort, and the complete machine heaviness, style is outmoded, cost is high, function singleness, effect is low, is not easy to carry and moves.

The purpose of the utility model aims to provide that a kind of novel structure is simple, cost is low, shearing force is big, rapid operation, and can shear steel plate, band steel, the round steel of certain specification, the multi-functional hand cutter of angle steel.

Fig. 1 is the utility model structural front view;

Fig. 2 is the utility model structure right view;

Fig. 3, Fig. 4 are the bottom knife three-dimensional view.

Fig. 5 is the cutter three-dimensional view.

Technical solution of the present utility model is: this multi-functional cutting machine, consisted of by body (7), cutter (3), bottom knife (6), lever head (1), toggle link (2), material-pressing rack (4), binder bolt (5), torsion spring (8), handle (9), lever head semiaxis (10), cutter semiaxis (11), body (7) is the twisted shape one-piece construction, bottom knife (6) two ends are the acute angle vertical section, cutter (3) one ends are installed by cutter semiaxis (11) and are connected body (7) middle part, cutter (3) other end is flexibly connected lever head (1) by toggle link (2), and cutter (3) both sides have blade, and lever head (1) end is connected with body (7) top movable by lever head semiaxis (10).

Be described in further detail below in conjunction with accompanying drawing: as Fig. 1, shown in Figure 2, this multi-functional hand cutter is by body (7), cutter (3), bottom knife (6), lever head (1), toggle link (2), binder frame (4), binder bolt (5), torsion spring (8), handle (9), lever head semiaxis (10), cutter semiaxis (11) constitutes, body (7) is the twisted shape single chip architecture, the employing high-strength cast iron is made, the bottom has only three legs as fixing feet, also has the little discharging angle that is particularly suitable for the cutting steel plate, the cutter bed of body (7) bottom partly has with bottom knife (6) installs the chamfering that matches, bottom knife (6) is fixed on the body (7) by set bolt, bottom knife (6) two ends are the acute angle vertical section, when placing separately, three-dimensional shape such as Fig. 3, special-shaped vertical section body shown in Figure 4, bottom knife of the present utility model (6) is installed, can shear the oblique angle or the angle breach of the various angles of angle steel, binder frame (4) is fixed on body (7) top, binder frame (4) lower end suit binder bolt (6) is adjusted binder bolt (5).Push down with it and to cut material, prevent upset and damage body or blade, torsion spring (8) is installed on lever head (1) and the lever head semiaxis (10), realize opening automatically of blade clip, cutter (3) one ends are installed by cutter semiaxis (11) and are connected body (7) middle part, cutter (3) rotates around cutter semiaxis (11), cutter (3) other end flexibly connects lever head (1) by toggle link (2), and lever head (1) end is connected with body (7) top movable by lever head semiaxis (10), lever head semiaxis (10) is fixed on the body (7), lever head (1) can rotate around lever head semiaxis (10), body (7) top, all have roundwood on the cutter (3) and cut off the hole, cut off operation to realize round steel.Cutter (3) is the symmetric body (as shown in Figure 5) of two sides band blade.

This multi-functional hand cutter, adopt the high-strength cast iron material to make one chip twisted shape body, the last bottom knife of adapted cantilevered semiaxis and special shape, the cutter both sides have blade, thereby valuable steel have greatly been saved, blade prolongs one times service life, transmission is by the reinforcement of hinged quadric chain, make that this machine is simple in structure, light, machine heavily has only 1/3～1/5 of like product, and cost only is 1/2～1/3 of a like product, shearing force is big, except that the cutting steel plate, also can cut off band steel, round steel and angle steel particularly can be chamfered 45 ° of oblique angles and 90 ° and other angle breach of steel, the function uniqueness, rapid operation, body is light to be taken, with low cost, is a kind of novel manual machine that is worthy to be popularized.
