Description
Technical field
The invention belongs to high pressure waterjet technical fields, and in particular to a kind of high-pressure water knife drilling method and bucket elevator conveying
Band.
Background technology
Water Cutting is also known as water knife, is a kind of equipment cut using high pressure water flow using High Pressure Water Jet Cutting Technology,
The lower automatic realization work pieces process of the consoles such as computer programming control, has many advantages, such as that inexpensive, easy to operate, yields is high.With pressure
Power divides the type of water knife：Including high-pressure type, low-pressure type and super-pressure three classes, generally using 100MPa as boundary, 100MPa with
Upper is high-pressure type, and 100MPa or less is low-pressure type, and 200MPa or more is superelevation die mould
Existing high pressure waterjet device and method, although have the advantages that it is various, due to the high pressure sprayed from water knife nozzle
Waterline, when passing through air to work piece cut face, under high pressure, conditions of high flow rate, suffered air drag can also be passed at double
Increase, causes waterline serious as jet path diverging is incremented by, due to there is this, on the one hand, the precision of cutting can be influenced；Separately
On the one hand, energy consumption and water consume are also increased.
And when cutting it is the damage for avoiding chip, flow from sputtering to components such as water knife nozzles, water knife nozzle can not be also close to
Workpiece surface is processed.
Conveyer belt is the important component of bucket elevator, by completing the conveying of material, bucket elevator conveyer belt with the cooperation of hopper
Quality and mounting stability with hopper, be directly related to the performance of bucket elevator.In use, most common problem
Be exactly conveyer belt be torn with hopper loosen, lead to the problem Producing reason, first, the intensity with conveyer belt itself is related；
Second, hopper is loosened has close association with the drilling quality on conveyer belt.
Punched on existing conveyer belt and mostly use mechanical stamping mode greatly, perforating by punching easy to produce pitch-row, aperture and
Shape it is irregular, so that the metallic framework in conveyer belt is fluffed, be more troublesome when wearing bolt in hopper mounting hole；While by
It is inconsistent in hole own form and aperture parameters, metapore is used for a long time and generates abrasion with bolt, hopper loosening, conveyer belt is caused to be opened
It splits, influences use quality and the service life of bucket elevator conveyer belt.
Such as Chinese patent（Application publication number CN 107856124A）It is disclosed " a kind of water-jet cutting machine easy to use and
Its application method ", including outline border are fixedly connected with sliding panel, the surface of the sliding panel between the both sides of the outline border inner wall

Side is fixedly connected with spring lever, and is fixedly connected on the left of the left end of spring lever and outline border inner wall, the right side of the movable plate
It is fixedly connected with steady rest, the present invention relates to water-jet cutting machine technical fields.The water-jet cutting machine easy to use has reached just
In the purpose for adjusting cutting head position, different positions can be cut, be convenient for the use of people, improve the practicality of device
Property, it prevents workpiece from shifting, ensure that the quality of cutting, conveniently adapt to different workpiece, improve the use scope of device, prevent
The only waste of resource so that device is more environmentally friendly, while saving production cost.
For another example Chinese patent（106827260 A of Authorization Notice No. CN）Disclosed " a kind of method and dress of high pressure waterjet
Set ", after transport mechanism receives and moveable processing platform is transmitted to processing stations, will movably it be added by elevating mechanism
Work platform drops to inside the pond of water-jet cutting machine；Carry out second step when, first pass through elevating mechanism will movably process it is flat
Platform lifts away from above the pond of water-jet cutting machine, then sends out water-jet cutting machine by the transport mechanism in water-jet cutting machine again.With
Prior art is compared, and has the advantages that so that water-jet cutting machine is come into operation in time, service efficiency is high.
High pressure waterjet device and method disclosed above still fails to solve the problems, such as that waterline is easily spread.
