Description

Iron shears hydraulic material pressing device

Technical field

The utility model relates to a kind of hydraulic material pressing device, specifically a kind of Iron shears hydraulic material pressing device.

Background technology

The Iron shears that uses does not generally have material pressing device at present, and when shearing iron charge, the meeting of the iron charge of cutting edge both sides very easily causes the shear tipping and cuts body distortion damage because the gravity effect is sunk, and the iron charge of mid portion can upwarp; Minority is provided with the Iron shears of material pressing device, and the pressure of material pressing device is controlled by the operator, if binder tightly can not cause iron charge to come off and shear precision is low, has a strong impact on operating efficiency and service life.

Summary of the invention

Goal of the invention of the present utility model is at the deficiency of existing shearing technique, and the Iron shears that a kind of sight line is good, pressure is big hydraulic material pressing device is provided.

The utility model is realized above-mentioned purpose by the following technical solutions: a kind of Iron shears hydraulic material pressing device, comprise that Iron shears cuts body, cut handle, stay cord, holding pad, also comprise fixed block, the binder lever, connecting rod, hydraulic cylinder, cylinder barrel, petroleum pipeline, piston, plug cock, the binder pillar, stage clip, push rod, connecting axle and steady pin, described fixed block is fixed in cuts body one side, hydraulic cylinder is fixed on the fixed block, be provided with the push rod affixed in this hydraulic cylinder with piston, push rod one end is fixed between two connecting rods with steady pin, the two connecting rod other ends are fixed in the lump with connecting axle and binder lever and cut on the body, reseting pressuring spring also is housed between two connecting rods, the bottom of hydraulic cylinder is connected with cylinder barrel, its inside is provided with the binder pillar, this binder pillar upper end is connected with plug cock, the plug cock below is socketed with stage clip, the lower end is connected with holding pad, on the cylinder barrel barrel tubing valve is housed, its top is communicated with hydraulic cylinder with the petroleum pipeline that cylinder barrel inside is connected as a single entity, the lower end of binder lever is fixed on connecting axle and cuts on the body, its upper end with stay cord with cut the handle be connected.

Compared with prior art, the beneficial effects of the utility model are: this Iron shears is simple in structure, easy to operate, time saving and energy saving with the hydraulic material pressing device, effectively solves tipping, cuts problem such as body damage, increase binder pressure, sight line is good, alleviates operator's workload, improves shear precision.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 be among Fig. 1 A-A to partial view.

Among the figure: binder lever 1, connecting plate 2, hydraulic cylinder 3, petroleum pipeline 4, fixed block 5, cylinder barrel 6, plug cock 7, holding pad 8, binder pillar 9, stage clip 10, tubing valve 11, connecting axle 12, reseting pressuring spring 13, piston 14, push rod 15, steady pin 16.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Referring to accompanying drawing, in the present embodiment, material pressing device comprises binder lever 1, connecting plate 2, hydraulic cylinder 3, petroleum pipeline 4, fixed block 5, cylinder barrel 6, plug cock 7, holding pad 8, binder pillar 9, stage clip 10, tubing valve 11, connecting axle 12, reseting pressuring spring 13, piston 14, push rod 15, steady pin 16.

Wherein: fixed block 5 is welded on a side of cutting body, hydraulic cylinder 3 usefulness connectors are fixedly connected on the fixed block 5, push rod 15 is equipped with in the inside of hydraulic cylinder 3, one end and the piston 14 of push rod 15 are affixed, its other end is fixed between two connecting rods 2 with steady pin 16, the other end clamping connection of two connecting rods 2 has binder lever 1, and with connecting axle 12 itself and binder lever 1 are fixed in the lump and cut on the body, between two connecting rods 2 reseting pressuring spring 13 is housed also, one end of reseting pressuring spring 13 is fixed on the connecting rod 2, the other end touches mutually with binder lever 1, the bottom of hydraulic cylinder 3 also is connected with cylinder barrel 6, its inside is provided with binder pillar 9, the upper end of this binder pillar 9 also is connected with plug cock 7, be socketed with stage clip 10 on the binder pillar 9 of these plug cock 7 belows, the lower end of binder pillar 9 is welded with rectangle holding pad 8, when this holding pad 8 remains static, its bottom is a little less than the Iron shears lower scissor blade, tubing valve 11 is equipped with on the barrel top of cylinder barrel 6, the top of this tubing valve 11, be communicated with the cylinder body of hydraulic cylinder 3 with the petroleum pipeline 4 that cylinder barrel 6 inside are connected as a single entity, the lower end of described binder lever 1 is fixed on connecting axle 12 and cuts on the body, its upper end with stay cord with cut the handle be connected.

Concrete using method of the present utility model is as follows: the reinforcing bar that will need to shear places between two cutting edges, hand is pinched and is cut handle, stay cord drives binder lever 1 and rotates, under the effect of connecting axle 12, thereby promote connecting rod 2 and promote push rod 15 with its motion, make the hydraulic oil of piston 14 compression hydraulic cylinders 3 inside, hydraulic oil is compressed into cylinder barrel 6 by petroleum pipeline 4, hydraulic oil extruding plug cock 7 promotes binder pillar 9 and presses down, to reach the purpose that compresses iron charge; Pull on dynamic pressure material lever 1, compress reseting pressuring spring 13, binder lever 1 rotational angle strengthens, and tubing valve 11 is compressed into, and is about to it and closes, and stops the hydraulic oil of cylinder barrel 6 inside to reflux.When iron charge upwarped, because stay cord strains at binder lever 1, its each parts compressed iron charge under pulling force and pressure effect, and it is loosening that iron charge is difficult for, and guarantees shear precision; After shearing finishes, unclamp and cut handle, under spring action, each parts can automatically restore to initial position.
