Description

The planer-type flying sawing machine

Technical field

The utility model relates to a kind of metallurgy industry flying sawing machine, especially planer-type flying sawing machine of the continuous straight-line cold-forming shapes of cutting automatically of being used for.

Background technology

At present, in the cold-forming shapes of cutting continuous rolling, the employed saw that flies is essentially single saw head, for big specification steel pipe cutting, has increased saw cutter diameter, has increased stroke, causes frictional resistance big, reduces saw cutter service life, has reduced the cutting quality of section.

Summary of the invention

The utility model provides a kind of cut surface precision height for solving the technical problem that exists in the known technology, and cutting efficiency is higher flies saw.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

The planer-type flying sawing machine, by lathe bed, lathe bed is provided with the round guide parallel with workpiece, along the reciprocating saw car of guide rail, the saw cutting mechanism of installing on the saw car, compositions such as workpiece level and vertical clamping device, the whole operation system is controlled by microcomputer, described saw cutting mechanism is two shaped as frame bogie side frames of parallel installation on the saw car, two bogie side frame upper surfaces respectively have two grooves, in groove by screw and bogie side frame vertical install two parallel, the crossbeam that also has the groove that matches, on two crossbeams, below on guide rail respectively is installed, by guide rail left slide and right slide are installed on two crossbeams, a left side, the main shaft that an output has the motor of belt pulley and has belt pulley respectively is installed on the right slide, the belt pulley of each main shaft one end and respectively be connected with driving belt between the belt pulley of motor separately, the other end of each main shaft respectively is equipped with the circular saw cutter, the feed cylinder that drives two slides also is installed on the side frames, the piston rod of two oil cylinders is connected with slide, the crossbeam top of two slides is equipped with two travel switches, the buting iron that prevents that two saw cuttves from colliding also is installed on two slides, the saw cutter protective cover that has cooling device also is installed on the saw car.

The utility model can also adopt following technical measures:

Described guide rail is a linear rolling track.

The alignment of shafts of described left and right slide is not contour.

Advantage and the good effect that the utlity model has are: owing to adopt the saw cutting mechanism of the two saws of planer-type, make the workpiece two-way simultaneous stressed, therefore stress balance has improved the quality of cut surface, it is more shallow than the single head saw to saw the cutter penetraction depth simultaneously, frictional force when having reduced sawing, improve saw cutter service life, shortened the time of cutting, improved efficient.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, reciprocating saw car 2 is installed on the lathe bed 1.Parallel two the shaped as frame bogie side frames 3,31 that are equipped with on the saw car 2 are vertically installed with two parallel beams 13,131, as shown in Figure 3 and Figure 4 on the side frames.In order to increase the coupling stiffness of side frames and two crossbeams, all have groove 18,12 in the lap-joint of bogie side frame and crossbeam, as shown in Figure 5 and Figure 6.Two linear

rolling tracks

15,16 and 151,161 respectively are installed on two crossbeam above and below.17,171, two slides of two slides are installed on same rail on two pairs of linear rolling tracks.The motor 9,91 that has belt pulley 7,71 is installed, as shown in Figure 2 on two slides respectively.Also be separately installed with main shaft 21,211 on two slides, in order to adapt to the big specification side of cutting, rectangular steel pipe, two alignments of shafts are not on a level height, as shown in Figure 4.One end of two main shafts is separately installed with belt pulley 5,51, as shown in Figure 4.The belt pulley of two main shafts is by the belt pulley of driving belt 6,61 connections two motor, and with this transfer motion power, the other end of two main shafts is installed saw cutter 14,141 respectively.An end that connects feed cylinder 8,81 piston rods in two slides respectively, the earthen pipe of two feed cylinders are connected on the bogie side frame 3,31, as shown in Figures 2 and 3.The workpiece grip mechanism 4 of clamping work pieces also is housed on the saw car.For the safety of high-speed cutting, on the saw car, protective cover 10 is installed also, and cooling water pipe 11 is housed in protective cover in order to cool off the saw cutter.On the crossbeam top of two slides two travel switches 20,201 are installed also in addition.In order to prevent two saw cuttves collisions, at the inner side edge of two slides the buting iron 19,191 that can adjust is installed respectively, control two is sawed cuttves apart in 5 millimeter.

Operating principle:

The computer control system that flies to saw is provided with adjustment, semi-automatic, auto state.When the state of adjustment, change the horizontal hydraulic pressure anchor clamps fixture block of different-thickness on the sport(s) car and the clamping stroke piece of adjustment vertical hydraulic anchor clamps according to the difference of pipe appearance and size.According to the steel pipe of different size, adjust on the sport(s) car about F.F., the worker of saw hair oil cylinder advance, the speed and the stroke of rewind down.When semiautomatic control, press the motion of starting button saw car, consistent with the speed of steel pipe when sport(s) car, sawing machine has been finished the clamping to steel pipe in rolling.At this moment, pressure switch or time-delay are signaled, when steel pipe during greater than 200 millimeters width; a left and right saw slide is by oil cylinder promotion separately on the saw car; about the F.F. simultaneously of saw cutter, the worker advances steel pipe is cut, when flying to saw high-speed cutting at a distance of 5 millimeters for two; there is mechanical buting iron to protect; electrical trip switch signals, and makes one to fly saw and return original position fast, flies saw in addition and continues the worker and advance; after the steel pipe cut-out, return original position fast by the travel switch signalling.When the steel pipe width can fly the disconnected steel pipe of sawing by one during less than 150 millimeters, fly to saw original position stop in addition.Afterwards, sport(s) car drives anchor clamps and rolled steel tube continues advanced in unison to saw car terminal point, is signaled by the lathe bed upper stroke switch, and level, vertical anchor clamps are unclamped simultaneously, and the reposition of saw car stops, and finishes a circulation under the semiautomatic control.

When auto state, fly to saw the working angles that can automatically finish continuously under the semiautomatic control, and automatically show scale cutting steel pipe length, counting automatically finishes until the steel pipe cutting of this specification.
