Abstract

A flexible perforated metal band on which the saw teeth with various forms which are made of diamond, alloy steel or general carbon steel are inlaid or the saw teeth are directly made up is driven by rotary pinned drum to make straight-line high-speed motion so as to saw and cut stone material, metalic or non-metalic materials, etc.. It can raise processing speed, save equipment investment, save electric power and steel material, and can save floor area, and is easy to implement processing automation.

Description

Flexible band saw

The present invention is intended to make a kind of novel flexible band-saw diamond that solves the sawing of field of stone processing stone material, uses this saw blade, and directly sawing goes out slab and 10 millimeters with lower thin sheet, and the processing method that makes this field is to automation, low cost, push away further at a high speed.

Dali Waste stone material sawing both at home and abroad now has the marble buhl saw, and thin plate singly cuts open machine etc. with two cutters; The sawing of the waste material of granite has big plate framework sand saw, thin plate to saw, singly cut open machine etc. with two cutter sand.The full-automatic gate-type stone material sawing machine that uses the present invention to make can substitute above three kinds of expensive stone machining equipments, can finish heavy-gauge sheeting processing, the light sheet processing of waste material equally, and once finish.

Purpose of the present invention:

The machine for sawing of application flexibility diamond saw blade manufacturing is mixed economical advanced figure place control system, makes processing of stone realize automation, reduce labor intensity, improve working (machining) efficiency, improve the stone material utilization rate, reduce equipment investment, save electric power and steel, reduce floor space.

The present invention has compared following advantage with existing processing of stone technology:

1. equipment investment reduces by 2/3 5. electric power saving 80%

2. the place reduce 1/2 6. personnel save 50%

3. improve working (machining) efficiency and 7. be convenient to realize automation

4. 8. diamond sawtooth is replaceable in stone material utilization rate raising 10%, reduces maintenance cost.

The present invention is by forming with lower member, and states its machining manufacture:

(1) flexible steel band assembly: with the thick steel band of 0.3-0.5, surperficial titanium-nitride superhard thin film layer, the centre is accurately stamped the location perforation and is stamped connecting hole and sawtooth installing hole (see figure 1) by specification

(2) manufacturing of sawtooth assembly sawtooth: the material of sawtooth can be high-carbon steel, steel alloy and diamond sawtooth, should process installing hole in the time of the processing sawtooth, shape has different shapes such as rectangle (see figure 2), triangle (see figure 3), cylindrical (see figure 4), square (see figure 5).Sawtooth is whole, and the centre has the slit of saw blade thickness, also can be two combining structure (see figure 6)s.This sawtooth also will plate the titanium nitride superhard film, to improve its wearability and antiseptic property.

(3) pin rolls assembly: the manufacturing that pin rolls requires accurately, needle gage should with position, steel band hole movingly, to reduce the transmission resistance, the pin side of rolling down should leave the space in the sawtooth place, all is attached to the surface that pin rolls to protect positive steel band, does not roll on and sawtooth is affixed on, sawtooth is evenly distributed on the tangent line that pin rolls, this just requires sawtooth as far as possible short, and distortion is little when crooked, to improve the (see figure 7) in service life of saw blade.Pin rolls surperficial titanium-nitride superhard film, to improve hardness and decay resistance.Each component diagram of the present invention and assembly drawing are seen Fig. 8, Fig. 9

(4) guiding rubber-surfaced roll: 4 rubber-surfaced roll directive wheels are equipped with in the present invention at the two ends of every blade saw, totally 8 of whole flexible band saws.Its effect has two:

1. guarantee the perpendicularity of flexible band saw and the depth of parallelism of two saw blades.

2. can regulate the distance between saw blade, to adapt to the thickness requirement of different stone material plates.(see figure 10)

(5) power source: the present invention can roll at any two pins and add that buncher drives, and also can add the driving buncher simultaneously on two wheels.

(6) as required, above-mentioned flexible band saw group can be used in combination side by side, to improve cutting-rate.(seeing Figure 11)

Claims

1. one kind studs with the sawtooth of the different shape that diamond, steel alloy or common high-carbon steel makes and the sawtooth of directly making by dress on flexible perforated metal band and the metal tape on metal tape, this flexible band saw is under the drive that one or more pin rolls, do the straight line high-speed motion, to finish sawing to stone material, metal or object such as nonmetal.

2. according to its feature 1 of claim 1 described flexible band saw be: flexible steel band with holes, refer to metal tape with elastic restoring force, as steel band, brass band, copper-manganese band etc., require metal tape to have elasticity and pliability, wear-resisting, endurance.

3. according to its feature 2 of the described flexible band saw of claim 1 be: dress studs with the sawtooth of the different shape of diamond, steel alloy or the manufacturing of common high-carbon steel on the metal tape, refer to that these saws adopt multiple manufacture method dress to tumble in, as: laser weld, riveted joint, spot welding, electric welding or gas welding, refer to that also these sawtooth have shape to comprise trapezoidal, rectangle, triangle, cylindrical, square etc., and on steel band, directly make sawtooth etc.

4. according to its feature 3 of the described flexible band saw of claim 1 be: flexible band saw is done the straight line high-speed motion under the drive that one or more pin rolls.Refer to that power source can motor-driven, also can diesel engine, gasoline engine or manpower drive.

According to the described flexible band saw of claim 1 to finish sawing to stone material, metal or non-metallic objectsit is not a metal object, the number that pointer rolls can have one or more according to different processing requests, other rollers can not be that pin rolls.Other refers to that processing object can be stone material or other rocks, metal or nonmetal (as timber etc.).
