Abstract

The utility model relates to a vertical two-shaft digital-control band sawing machine which comprises a machine body, a saw frame, a workbench, a chip removal device, a cramping apparatus and a control device. The vertical two-shaft digital-control band sawing machine is characterized in that an addle arranged on the workbench is a cross-shaped saddle composed of a longitudinal and a transversal saddles; each cross saddle is correspondingly provided with a guide rail and a screw rod, connected with a digital-control device through an actuating motor and controlled to move by the digital-control device. The vertical two-shaft digital-control band sawing machine has the advantages that the utility model cuts different plane surfaces, different number and optional positions, and various pattern curves can be sawn rapidly and exactly. The utility model can become a board band sawing machine by locking the transversal saddle, and can be used for cutting the casting head of the automobile aluminum alloy casting and processing moulds and various machine parts.

Description

Vertical two-axis numerical control band sawing machine

The utility model relates to a kind of vertical two-axis numerical control band sawing machine that is used for metal cutting.

Existing vertical band sawing machine on the market, workbench has only vertical planker not have cross slide, and vertically planker also is to do reciprocating linear motion with artificial promotion or with oil cylinder, can not make X-Y two axis coordinate motions, there is following shortcoming in such band sawing machine: because workbench can only rectilinear motion, add man-hour like this, must promote by manual shape of pressing the working surface line, do feeding processing by line, its machining accuracy is poor, the inhomogeneous processing fineness that causes of hand push table feed is poor, and easily goes out industrial accident, and efficient is also low.

The purpose of this utility model is for overcoming the prior art shortcoming, provide the vertical two-axis numerical control band sawing machine that has horizontal, vertical planker and controlled by numerical control device.

The technical solution of the utility model is to realize like this, vertical two-axis numerical control band sawing machine comprises lathe bed and is located at saw frame on the lathe bed, workbench, chip removal device, anchor clamps and control device, its characteristics are, set planker is a cross saddle on the workbench, it is made up of cross slide and vertical planker, every block of planker is corresponding to be equipped with two guide rails, screw mandrel constitutes, in length and breadth planker respectively the servomotor by separately be connected with the two-axis numerical control device, by the motion of numerical control device control cross saddle, clamping workpiece on work top is done fast or the work feed campaign by the instruction of numerical control device.

The utility model embodiment is described further in conjunction with the accompanying drawings.

By Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, vertical two-axis numerical control band sawing machine comprises lathe bed 1 and is located at saw frame 2, workbench, cross saddle on the lathe bed 1, chip removal device 15, anchor clamps 6 and numerical control device 11, on the workbench set cross saddle by cross slide 8 and vertically planker 9 forms, every block of planker is that each is corresponding to

guide rail

16,17 for cross slide and vertical planker,

screw mandrel

24,18,

servomotor

21,23 constitutes, and the also available tooth bar of screw mandrel replaces, and servomotor also available step motor substitutes.The servomotor of planker by separately is connected with two-axis numerical control device 11 in length and breadth, servomotor is done corresponding rotation by the instruction of two Shaft and NC Machining Test devices, the workpiece of clamping on work top done fast or the work feed campaign by the instruction of two-axis numerical control device, two-axis numerical control device ONC-2102 is by built-in programmable controller and driver MSM5A2A1A, encoder is formed, encoder and servomotor are integrated, servomotor adopts MSM102AIC, the two-axis numerical control device has fault self-diagnosis function and other miscellaneous functions, the positioning accuracy height, good reproducibility, programming is convenient, good reliability.

The working condition of present embodiment can be done an explanation by Fig. 1～Fig. 5, be provided with driven pulley 5 and driving wheel 12 in the saw frame 2, bands for band 4, two places up and down at bands for band are provided with directive wheel 13, the tensioning degree of bands for band is regulated by band saw blade tensioner 3, during work, bands for band 4 is motionless, the cutting feeding by numerical control device respectively to leading screw, gear, vertical transmission mechanism 10 formed by motor and horizontal transmission mechanism 7 sends instruction, be that servomotor 22 turns round according to the instruction of numerical control device, through timing belt pulley 19, synchronous belt 20 and synchronous pulley 21, order about ball screw 18 rotations, make the vertical planker that is installed on the rolling guide 17 on lathe bed 1, obtain corresponding sports by programmable device regulated procedure, same servomotor 23 is also under the instruction of numerical control device, by synchronous pulley 25, synchronous belt 26, synchronous pulley 27 and ball screw 24, make the cross slide 8 that is installed on the rolling guide 16 also in accordance with regulations program obtain corresponding sports, workpiece to be machined is by the anchor clamps 6 that are arranged on the cross slide 8, carries out clamping by hydraulic means 14.When sawing workpieces, cut a large amount of metal fillings are by being placed in by motor, decelerator, the chip removal device 15 that conveying screw rod and chip area are formed is discharged in the storage bits case of lathe bed outside, in time getting rid of the smear metal in the saw blade chip pocket, also is provided with rotating brush wheel at saw frame 2.

Because the utility model characteristics are the workbench on the sawing machine frame cross saddle is arranged, and control its vector motion and speed by numerical control device, thereby can be at a high speed, accurately, reliable sawing Different Plane automatically, varying number, the otch of optional position, but the also curve of sawing different shape, for example can excise not dead head (as shown in Figure 6) at grade, the cutting shaped face, the folding face, the ear groove, circular hole, curved surface (as shown in Figure 7), form of gear tooth, and cutting different shape goods group etc., after the cross slide locking, then become the sheet material band sawing machine, therefore, the utility model can be applicable to the cutting of aluminium alloy car casting pressing port, mould and the processing of various machine components.
