Angle steel corner cut Digit Control Machine Tool
The utility model relates to a kind of Digit Control Machine Tool, particularly a kind of angle steel corner cut Digit Control Machine Tool.
At present, the iron tower of power transmission line grade improves (750,000 and 1,000,000 volts of transmission lines of electricity), and the strength of materials of the used angle steel of iron tower has been had higher requirement.Present angle steel cornering machine can not satisfy 200 * 200 * 20 big angle steel to ∠; The angle steel of high strength material carries out corner cut, because of angle steel corner cut angle changes, needs to regulate the angle of the relative cutter of angle steel; Angle steel to big specification; Rotate if desired, not only need change big power but also need change big space, regulate inconvenient.And existing big specification angle steel corner cut is through flame cutting, sawing machine sawing.
All there is weak point in the processing method of these two kinds of forms:
1, flame cutting, though this processing mode is easy to operate, this processing technology is to the intensity of angle steel own, material has destruction, and the flame cut quality is not high, and environment is polluted.Angle steel for big specification in the UHV transmission line bans use of this processing mode.
2, this processing mode is adopted in sawing machine sawing, troublesome poeration, and working (machining) efficiency is lower.

In order to make upper tool post and pressure head be easy to when mounted be connected, the bottom surface of described pressure head is provided with T type groove, is fixed with connecting axle on the upper tool post, and the upper end of connecting axle is provided with round boss, and the round boss on the connecting axle hangs in the T type groove.
Said vertical guider comprises and is fixed on down the vertical guide plate of polylith on the tool rest, and the vertical guide plate of polylith surrounds a vertical guide groove, and upper tool post is stuck in the vertical guide groove.It is big that this vertical guider bears unbalance loading, and guiding accuracy is high, improves lathe stability greatly.
In order to reduce the wearing and tearing of guide plate, described upper tool post is provided with the self-lubricating plate that contacts with guide plate.
For the ease of two faces of fly-cutting angle steel, described cutter comprises that two are arranged in L shaped blade, and described bottom knife comprises that two are arranged in L shaped blade.
In order to be suitable for cutting the angle steel of different-thickness, described two bottom knife are provided with strip hole, are provided with the bolt that is connected with following tool rest in the strip hole on two bottom knife, are fixed with L shaped lath on the following tool rest, and lath is provided with the screw that is against on the bottom knife knife back.
For the ease of manually control mould rotation, said driving mechanism comprises worm and gear group and rocking handle, and the worm-wheel shaft of worm and gear group vertically is provided with, and following tool rest is fixed on the worm-wheel shaft of worm and gear group, and worm screw is connected with rocking handle.Only rotation crank can be adjusted shearing inclination arbitrarily gently.Do not need the artificial angle steel that moves, just can shear arbitrarily angledly, manually-operated makes things convenient for.
The beneficial effect of the utility model: when the utility model need be regulated at cutting angle, need not to rotate angle steel, only need to rotate mould, be fit to angle steel corner cut, improved corner cut efficient and crudy greatly to big specification, high strength material.And this lathe takes up room little.Be suitable for processing big specification angle iron component in the UHV transmission line.

The specific embodiment
A kind of specific embodiment shown in Fig. 1-4 comprises main frame, mould 6, hydraulic system 5 and electrical system 1.
As depicted in figs. 1 and 2, main frame comprises lathe bed 4, oil cylinder 3 and pressure head 2, and the cylinder body of oil cylinder 3 vertically is fixed on the lathe bed 4, the piston rod of oil cylinder 3 down, pressure head 2 is fixed on the piston rod of oil cylinder 3.
Like Fig. 3 and shown in Figure 4; Mould 6 comprises upper tool post 9, following tool rest 17, cutter 11 and bottom knife 16; Upper tool post 9 slides up and down through vertical guider with following tool rest 17 and is connected; Vertical guider comprises and is fixed on down the vertical guide plate 10 of polylith on the tool rest 17, and the vertical guide plate 10 of polylith surrounds a vertical guide groove, and upper tool post 9 is stuck in the vertical guide groove; Upper tool post 9 is provided with the self-lubricating plate 14 that contacts with guide plate 10, and self-lubricating plate 14 can be the little and wear-resisting plate bodys of surface roughness such as copper coin.Cutter 11 comprises that two are fixed on the upper tool post 9 and are arranged in L shaped blade; Bottom knife 16 comprises that two are arranged on down on the tool rest 17 and are arranged in L shaped blade; The position of the blade of the blade of cutter 11 and bottom knife 16 is to corresponding, and bottom knife 16 is provided with strip hole, and the length direction of strip hole is vertical with the length direction of the blade of bottom knife 16; Be provided with the bolt that is connected with following tool rest 17 in the strip hole on two bottom knife 16; Be fixed with L shaped lath 15 on the following tool rest 17, lath 15 is provided with the screw that is against on bottom knife 16 knife back, through the position of bolt on adjustment screw and the bottom knife 16; Can regulate bottom knife 16 and cutter 11 gap in the horizontal, to be suitable for cutting the angle steel of different-thickness.
The bottom surface of pressure head 2 is provided with T type groove, is fixed with connecting axle 7 on the upper tool post 9, and the upper end of connecting axle 7 is provided with round boss, and the round boss on the connecting axle 7 hangs in the T type groove, between the downside of round boss and T type groove, is provided with thrust washer 8 on the connecting axle 7.
