Bandsaw Metal is a high-performance equipment, responsible for the implementation of a number of functions, such as metal stamping and cutting a variety of durable and high-strength materials.This kind of equipment is used quite successfully and in the manufacture of steel structures, and in the construction industry to make a quick cut any material.Through the use of a closed thin steel strip serving as a cutting element band saw, saw through the workpiece straight line completely.
Device features
If we look at the manual band saw for metal in more detail, it is similar to a jigsaw, since their work is similar to the scheme.There is only one difference - a closed web which is connected to the ring by welding, makes no reciprocating motion, contour and two pulleys in the same direction.This arrangement enables movement longer belt life fabric and also prevents the saw blunt too quickly.That is why for band saw machines do not become dull very quickly, that is, they do not need to be replaced too often.Small rough plane cutting eliminates the need for the production of surface finishing.
If you are using a manual band saw for metal, cutting the rolled profiles and pipes will be the highest quality.Due to the special design of the equipment it is possible to reduce power consumption and minimize the loss of expensive materials.This is achieved by the fact that the cutting of metal in this case is done with a minimum width of cut.That is why these machines are increasingly being used where the works are carried out related to reveal expensive metals and alloys, as well as parts with thin walls.
Efficiency of band equipment
If you need a band saw for metal, you need to know that the market is currently rife with equipment which is operated in manual, automatic or semi-automatic mode.Hand tools are easy to use, maximum reliability, as their design is not burdened with electronic elements, often coming out of the system.Their work is carried out with a certain force and speed set in advance.
Gravity machines
These devices get their name because the cutting of metal workpieces is carried out by the pressure of the weight of the console on the processed material.For the adjustment of the speed of the hydraulic cylinders are responsible and butterfly valves.Unlike ribbon cutting it consists in the fact that the tooth pitch is dependent on the web being cut profile.
Execution Tape equipment can vary significantly.This criterion makes it possible to identify some types of machines.
console machine for cutting .In this case, the saw frame (console) makes movement by a hinge.These models are used for cutting pipes shaped profile, high-quality and continuous rolling.
gooseneck, two-column and portal .The first type is characterized by a horizontal frame saw, which descends along the rack.The double column frame makes a motion along these two columns.They are used mainly for the miter and complex processing.Gantry machines are made in the form of a fixed table gantry.This device is used during operations with materials that are difficult to handle.
Vertical band saw for metal .Use it to cut metal on any line, straight or curved.In this case, the workpiece is fed manually into the working area, and the saw frame remains fixed.
Rotary horizontal machine for cutting .In this case the rotation about the axis of the frame is carried out in one or two directions at a right angle relative to the axis of the part.This arrangement makes it possible to carry out cuts at various angles, as well as instantaneous migration miter angle.
Advantages devices
Bandsaw Metal has a whole set of advantages in comparison with previously released fellow, morally obsolete.Precision cutting of such a device as high as possible, and the resulting surface is of excellent quality.Manufacturer resulting receives substantial material savings, and the presence of on-site cutting burrs and nicks can be forgotten.Technique described type allows machining packages.You can use it to cut like a normal tube rolling, and continuous billet.Bandsaw Metal characterized sophisticated design, thereby ensuring the smooth progress of the web and the high speed of the operator.The mechanism is quite a long time due to the presence of the cooling system.
How it works in all devices of this category used the same principle: the operator to manually set the workpiece on the machine, after which she served until it stops, and then automatically takes the entire cycle, including material clamping, lifting of the saw frame andits filing, unclamping.This equipment is characterized by the highest performance, and the ability to function in a fairly heavy loads in a small batch or unit production.As the cutting part of the machine used steel ribbon of small thickness.In one of its edges it has teeth, and it's called cutting, or the front and the second - back.
Appointment machines
machines that operate with metal blanks are used quite actively in the field of mechanical engineering.They are used for cutting non-ferrous metals, shaped profile pipes in size, as well as solid rental.Among its advantages include greater accuracy, higher productivity, reduced consumption of materials.Band saws for metal, the price of which is quite high for the smallest model starts at 28,000 rubles, allow to obtain the output large amounts of products, and ensure the durability of drinking in case of correct selection of a material to be treated.
Advantages of
have machining on band saws, there are a number of advantages:
- precision cutting;
- quality surfaces are cut;
- the minimum width of cut, so the material is consumed sparingly;
- cutting pieces packages.
If existing production requires updating or improvement, the most right will have the choice of semi-automatic band saws.
Automatic equipment
for this category is characterized by minimal operator involvement in the process, which significantly facilitates the work.To control the equipment used by the TNC, independently calculates all necessary action mechanisms.In the mass production of automatic band saw for metal shows itself at its best.Durability and reliability of parts, high accuracy and high quality of cut allows to implement with the help of the most complex tasks.
Semiautomatic two-column machines
This equipment is a high performance, and use it mainly for work with different steels and alloys.In particular, they made via metal cutting continuous rolling, as well as elements with a rather large diameter.They are used for thin-walled material: profiles, pipes and others.
Features of
as structural parts for the double column band saw machines are heavy-duty cast iron.They are designed to protect the materials processed by the smallest vibration, and also from strong shocks and bumps.The movement of the bracket is carried out on the four-digit guide.These parts are characterized by high load capacity, which provides an opportunity for them to work successfully with forgings, large parts, as well as other elements.Operation of this equipment in semi-automatic cycle is ensured by a special hydraulic system, which is characterized by the presence of electrical control.
two-column semi-automatic machines for cutting perpendicular
This kind of equipment is characterized by the presence of the saw frame, placed horizontally.When a task set by the operator, this element makes movement between a pair of racks arranged vertically.Saw frame to the frame combines mobile connection.Its stiffness in combination with reliability of the parts allows the creation of high pressure on the workpiece, which is directed as precisely as possible.
Heavy machines for cutting workpieces with large dimensions
Reserve data rigidity machines can use them for cutting pieces of large size and materials, which are badly treated.This equipment is used in steel mills.Also, stores are used to store metals.In addition, they can be used in shops, in the areas of procurement of various types of high-tech enterprises, where to complete the work requires the highest performance on each piece of equipment.
Features works on machines
work on hand band saws - a process rather complicated and time-consuming, as all operations, particularly the clamp and feed the material into the cutting area, turn, lowering and raising of the saw frame, blade tension, etc.does he work.Therefore, they are usually used in small batch and unit production, which are characterized by low volume of production.Pila tape for machine tools, in this case, too, used a kind.
work on semi-automatic machine is much easier, as the manual is only required to drive the workpiece.This equipment is appropriate to use even in the medium series.Speaking of automatic machines, it is important to note here their independence in terms of doing all the work.That is why they are actively used in mass and large-scale production.For such machines may require welding band saw, but it is used special equipment.
Methods ribbon cutting
To achieve these goals, it is required to choose the tape web having the desired pitch of the teeth.This takes into account a number of factors, among which the most important is the profile of sawn blanks.And the sharpening of band saws to be the highest quality.In practice, the selection of the desired blade pitch used special tables.When calculating step webs have to remember that at the moment of cutting in contact with the workpiece tooth is 3-4.And there is not so important, what it uses band saw (price it is 10 or 250 thousand rubles), you must select the correct size.
