Description

A kind of multi-line cutting machine

Technical field

The utility model relates to material cutting equipment, refers to a kind of multi-line cutting machine especially.

Background technology

Multi-line cutting machine is a kind of equipment being used for the hard brittle material such as cutting silicon wafer, semiconductor, the principle of multi-thread process technology grinding-material is brought into the machining area of material to be cut, moved back and forth at a high speed by many steel wires of machining area, be cut into the hundreds of even technology of thousands of by disposable for material to be processed.Existing multi-line cutting machine comprises the lifting body that a Multi-wire cutting device and are equipped with workpiece to be added, and lifting body is positioned at the top of cutter sweep, and elevating movement direction is vertical with many lines of cut, is realized the feeding of workpiece by the decline of lifting body.But the workpiece of shape for the change of cylindrical or other cut surfaces, along with the decline of lifting body, going deep into of cutting, the length that workpiece to be added contact with line of cut increases, Cutting Drag increase, and cutting speed is slack-off, cutting efficiency reduction.

Utility model content

In view of this, the purpose of this utility model is that proposing one can accelerate cutting speed, improves the multi-line cutting machine of cutting efficiency.

Based on the multi-line cutting machine that above-mentioned purpose the utility model provides, for cutting columniform workpiece or becoming the workpiece of large non-cylindrical from bottom to top at least partly with line of cut contact area, described multi-line cutting machine comprises lifting part and is positioned at the standing part of described lifting beneath portions, described standing part comprises worm and worm wheel, described worm screw is connected rotationally with the bottom of described lifting part, and vertical with the described lifting direction being elevated part, described worm gear to be positioned at below described worm screw and with described worm engaging;

Carry out in the process of cutting at described multi-line cutting machine, described worm screw is rotated, and drives described worm gear to swing in the perpendicular parallel with work piece cut face centered by the front end central shaft of its bottom.

Preferably, described lifting unit divides and comprises slideway, leading screw, two tracks be arranged in parallel and multiple slide block, multiple described slide block is positioned at described slideway both sides, and be slidably matched with two described tracks, described leading screw is set in parallel in two described track centre, described leading screw is connected rotationally with described slideway, and described screw turns drives described slideway and described slide block to slide on the track.

Preferably, based on the central shaft parallel with described lifting direction, described worm gear swings in the scope of ± 9 °.

Preferably, described worm screw is rotated by driven by motor.

As can be seen from above, the multi-line cutting machine that the utility model provides, the length of line of cut and absorption surface to be added become large cutting speed reduce time, by making workpiece axial-rotation to be added, reduce Cutting Drag, thus accelerate cutting speed, improve cutting efficiency.The utility model regulates the anglec of rotation of to be processed by worm gear, worm screw, and structure is simple, easy to operate.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.

As a preferred embodiment, as shown in Figure 1, figure middle and upper part is the lifting part of multi-line cutting machine, lifting beneath portions is standing part, for fixing workpiece 13 to be added, standing part lower triangular part is cutter sweep, after standing part installs workpiece 13 to be added, drive rise and fall by lifting part, realize the feeding of workpiece 13 to be added.

The lifting part of multi-line cutting machine is fixed on workbench 1 by slideway support 2, and track 4 is positioned on slideway support 2 in vertical two, and leading screw 5 is positioned in the middle of two tracks 4, and parallel with track 4, and slide block 3 is positioned on track 4, and slideway 6 two ends are fixed on slide block 3.Can realize slideway 6 by the rotation of leading screw 5 and be parallel to sliding up and down of workbench 1, now fixing with slideway 6 slide block 3 slides up and down on track 4 with moving up and down of slideway 6.

The below of multi-line cutting machine lifting part is standing part, wherein worm screw installing plate 7 is connected with slideway 6 bottom, worm screw 8 is fixed on worm screw installing plate 7, worm screw 8 is vertical with the glide direction of slideway 6, the side of worm screw 8 is motor 12, worm gear 9 is positioned at below worm screw 8, engage with worm screw 8, for waving slideway 10 between worm gear 9 and workbench 1, for fixing workpiece 13 to be added, wave slideway 10 top to be connected with bottom slideway 6, worm gear 9 lower end is front end central shaft 11, waves slideway 10 and is fixedly connected with worm gear 9 by front end central shaft 11.

As shown in Figure 2, during use, be fixed on by workpiece 13 to be added and wave in slideway 10 and clamp, one end of the central shaft of workpiece 13 to be added overlaps with front end central shaft 11.

When cutting, driven by motor leading screw 5 is utilized to rotate, slideway 6 and slide block 3 slide downward on track 4, and drive workpiece 13 to be added to move downward, roller 14 on cutter sweep is tied with several line of cut left and right high-speed motions, to cut the workpiece to be added 13 of vertical drop, the cut surface of workpiece 13 to be added is its cross section parallel with workbench 1.

Because workpiece 13 to be added and the contact surface of line of cut partly become large from bottom to top, along with workpiece 13 to be added moves down gradually, increase with line of cut contact surface, the contact length of line of cut and workpiece to be added 13 becomes greatly, and Cutting Drag becomes large, and cutting progress is slack-off, now motor 12 drives worm screw 8 to rotate, worm gear 9 thereupon with front end central shaft 11 for axle center, swing in the scope of ± 9 °, worm gear 9 swing plane parallel with the cut surface of workpiece 13 to be added; Front end central shaft 11 rotates with worm gear 9, and drives workpiece 13 axial rotation to be added, and rotational angle is similarly ± and 9 °.

The time that motor 12 is opened artificially determines according to the cutting progress in process, can open when observing cutting speed and being slack-off, also can determine that a time point is opened.

Swing angle ± 9 ° of worm gear are an empirical value, find that this angle is best angle in great many of experiments process, adopt this swing angle at utmost can accelerate cutting speed.

As shown in Figure 3, when workpiece 13 to be added normally declines, as shown by the solid line, along with cutting is goed deep into, the length that line of cut contacts with workpiece 13 to be added increases gradually, and cutting speed is slack-off for cut surface and line of cut; When worm screw 8 is rotated, when worm gear 9 swings, front end central shaft 11 rotates, workpiece 13 to be added rotates thereupon, cut surface and line of cut shown in dotted line, now contact with line of cut for do not rotate time cut surface one end, the area of workpiece 13 to be added and line of cut contact surface reduces, the length that line of cut contacts with workpiece 13 to be added as shown in Figure 3 reduces, thus accelerates cutting speed, improves cutting efficiency.

Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any amendment of making, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
