Description

Hand hydraulic dual purpose machine for shearing plate and folding plate

The utility model relates to the dual-purpose machine of a kind of hand-hydraulic shear bending, be applicable to that thickness is below 2.5 millimeters, width is less than the shear and the bending of 600 millimeters sheet metal.

What the shear of sheet metal and bending were adopted usually is special-purpose large and medium-sized machinery, and not only price is expensive, floor space is big, the most important thing is with electric power to be power source.For small processing factory, township enterprise, the area of particularly not having electricity, few electricity is unfavorable.

At the deficiencies in the prior art, the purpose of this utility model provides the dual-purpose machine of a hand-hydraulic shear bending.Can shear also can bending, and cost is low, floor space is little, and is easy to operate, reliable operation.Be applicable to that township enterprise, scientific experiment unit are shear and the bending of width below 2.5 millimeters less than 600 millimeters sheet metal to thickness.

Key point of the present utility model is to adopt hydraulic principle, has both taked method that hydraulic jack is decomposed, and the plunger tip that utilizes jack is the sill jack-up of moving knife fixedly, reaches shear or bending by moving knife and quiet cutter.

The utility model has following several characteristics:

1, consumed power not, floor space is little, low price;

2, dual-use, easy to operate, reliable operation.

Therefore, the utlity model has tangible progressive meaning and good effect, have very big development prospect.

Below in conjunction with accompanying drawing, exemplary embodiments of the present utility model is set forth.

Fig. 1, front view.Fig. 2, plate shearing machine structural representation.

Fig. 3, bender structural representation.

Embodiment.See Fig. 1.With bolt 26 fixed head 18 is fixed on the base 15.On fixed head 18, be fixed with both hydraulic control parts of jack of manual jack 1(); Be fixed with leading screw seat 3 between two guide pin bushings 12.One side of leading screw seat 3 has a slotted hole 4(and sees Fig. 2), both main body jack-up parts of jack of leading screw 11 plunger tip 10(are equipped with at 3 center) plunger tip 10 below be oil pocket 22, lock female 21 hydraulic oil pipes 2 in oil pocket 22 bottom sides by slotted hole 4 usefulness hydraulic tube bolts and join with manual jack 1, the setting of slotted hole 4 is for mobile usefulness when leading screw 11 oscilaltions.

Fig. 1 is seen on top at leading screw seat 3, an annular groove 5 is arranged, pressure bearing 9 is arranged at the top, be stamped a mother lead screw 8 above the top, on 8, there are handgrip 7 and steel ball, spring, jackscrew 6 to rotate handgrip 7, mother lead screw 8 is rotated, because in the annular groove 5 of steel ball, spring, jackscrew 6 embedding leading screw seats 3, limited moving up and down of mother lead screw 8, made that leading screw 11 can fast rise or decline and then drive the liter of plunger tip 10 or fall.

Be furnished with guide pillar 13 in two guide pin bushings 12, guide pillar 13 is fixed on down on horizontal 14, shear moving knife 23 support 33(is housed on 14 sees Fig. 1, Fig. 2).

Two support arms 16 are equipped with in the outside at 15 two covers 12 of base, the quiet cutter 17(of shear is housed on 16 sees Fig. 1, Fig. 2), be equipped with by screw rod 28 in 17 front, nut 27, spring 34, pressing plate crossbeam 29,32 compositions and the presser device that can under the guiding of bolt 31 slotted holes 30, do the vertical direction slip of pressing plate.(seeing Fig. 1, Fig. 2).

The utility model is to realize shear like this.

The sheet material 35 that at first will draw line is placed on the support 33 and stretches out shear moving knife 23(and see Fig. 2), the boss 36(that rotation handgrip 7 makes 10 risings of mother lead screw 8 drive leading screws 11 plunger tips withstand sill 14 sees Fig. 1), along with the continuation rising pressing plate 32 of plunger tip 10 is at first pushed down sheet material 35, when sheet material 35 and upper slitter are the quiet cutter 17 of shear when connecing erosion, handgrip 7 stops operating.At this moment see Fig. 2 with the manual pressure handle 20(that presses jack on hand down), make hydraulic oil be pressed into oil pocket 22 and thereby plunger tip 10 jack-up (see figure 1) jack-up shear moving knife 23(seen Fig. 2) until sheet material 35 is cut off, stop to press handgrip 20 this moment, unclamp oil-draining locknut 19, backward rotation handgrip 7 descends leading screw 11 plunger tips 10, under the gravity effect of pressing plate 32 and sill 14 etc., shear moving knife 23 is descended, return to initial position, finish an overall process of shear.

The bending of sheet metal is to realize like this.(see figure 3)

At first the needs according to the bending angle install the quiet cutter 24 of bending, bending moving knife 25.Operating process when in addition, the whole operation process is with shear is identical.

Shear moving knife 23, bending moving knife 25; The quiet cutter 17 of shear, the quiet cutter 24 of bending; Can be made of one or two bodies according to actual conditions.The quiet cutter 17 of shear is 2～8 ° with horizontal angle and is advisable.

As select for use 6 tons jack to decompose when installing, the sheet metal thickness of its shear bending is:

Shear thickness is below 2.5 millimeters; 600 millimeters of width:

Bending, when thickness is 2 millimeters 300 millimeters of width:

Width was 500 millimeters when thickness was 1.5 millimeters:

Thickness is below 1.2 millimeters the time, and width is 600 millimeters.
