design cutting machine
Anywork related to the metal, it requires processing and cutting, which uses specialized cutting machines.The use of this device is very wide: from domestic use to large enterprises and factories.
It should be noted that the machines of this type represent a device that allows you to make cross-cutting - the workpiece
cutting machine is able to saw the details of any type of metal - aluminum and PVC profile to thick pieces of steel.The profile can be cut from two angles: a direct and sharp at 45 degrees.Using cutting machine can cut and cut pipes of large and small diameters.
The most important element of the instrument, his "heart" is the electric motor and the cutting disc, which are connected to each other by means of gears or belts.Each transmission has its advantages over the other.For example, the belt is characterized by a calm way, is more resistant to overload and emits less noise.It can be installed even on a powerful cutting equipment.
A gear is capable to take up little space and because of this characteristic is suitable for a small home-made cutting machine.Therefore, the choice of the cutting machine is necessary to pay attention to the type of transmission.
Almost all models are equipped with machines abrasive wheels, but sometimes there are aggregates and with hard disks.In addition, all cutting saw blades equipped with clutches, which are capable of securely fixing the workpiece.
Choice cutting machine
If you need to select the cutting machine, it is recommended to pay attention to certain features and capabilities of the device, which depend on the conditions for its use.One has already been mentioned above - the presence of gears or belts.And now should lead other features.
Motor power - this parameter on which will depend directly on the performance of equipment.Cutting machines usually have a high power of about 2000 watts.Next
should go to the characterization of the number of revolutions of the disc.The more frequent the cutting disc rotates, the speed of operation of the device will be higher as a whole.Moreover, the number of revolutions may affect the quality of the products obtained.
's documentation, which has a certain diameter of the disc manual cutting machine.From the maximum size will depend on the maximum height of the details that you can be treated on a similar device.Dependency in this case is directly proportional to: the larger the diameter - the larger the height, the smaller the diameter - the lower the height.Usually cutting machines equipped discs whose diameter is within 400 millimeters.
Another important characteristic - the cutting angle, which is able to determine the position of the workpiece during the cutting with respect to the cutting disc.This figure can be adjusted typically from a right angle to an acute angle of 45 degrees.
And the last thing you should look - the weight of the cutting machine.The range of today's retailers are mobile models, but there are quite bulky, more than a hundred kilograms.
Classification of cutting machines according to the number of cutting heads
variety of cutting machines differ among themselves their own parameters: the number of cutting heads, cutting capability at an adjustable angle, a way of feeding the saw blade.Depending on the number of cutting heads, which are present in the structure of the cutting machine, and isolated single miter machines.
As the name implies, you can understand that this cutting machine is equipped with only one cutting tool - the saw blade.It follows that such a self-made metal cutting machine is compared with other lower performance.To cut a blank piece for frame profile, you need to perform more than one operation, but two.
installs on such machines, roller conveyors - a device by which measure the length of the machined profile.Roller conveyors are input and output.The output is equipped with thrust-measuring device shown in a simple metric ruler.
however, is manual assembly and optical performance or a special automatic, which are used in a high-precision models.Attachments of the first embodiment is almost completely eliminates errors at work and marriage in manufacturing.
Dvugolovochnye cutting machines, as opposed to single-head, they have in their two cutting tool designs.This allows the frame profile cut in a single operation, in other words - in a single pass.In this equipment, one cutting head is fixed and the other can be moved to the desired distance.
To measure the distance, which are heads in the equipment used = metric ruler, complete with special optical or digital display visor.Also, instead of using the built-line taken the automatic movement of the working head a certain distance.
classification tools for applying the cutting tool
By type of tool feed, which carries out cutting, cutting machines are drawings with a pendulum, front and bottom feed.In cutting machines with pendulum feed sawing disk is supplied from above.And if cutting machine has one such tool, the saw blade is supplied in manual or automatic mode.If the machine is characterized by dual-head snap, then saw feeder takes place exclusively in the automatic mode.
To cut angle wheels in a vertical plane can rotate.In some models, it provides the possibility of horizontal blade pitch.In the cutting equipment with a pendulum feed, tilt and rotate the saw blade does not have an automated mode.All should prodelyvat manually.
have cutting machines, which are equipped with front loading of the cutting tool automatically changes the tilt of the disc.On sale there are special models, equipped with special electronic control units that allow the machine to memory to make up to 99 different types of profiles that can be cut.
There is the possibility to calculate all parameters of cut, and it is automatic.Cutting machines with front loading of the cutting tool can memorize up to 100 different types of designs of windows and doors.In many machines, by recording certain commands on a floppy disk, in memory of the machine, you can download maps of cuts, in contrast to the improvised cutting machines of grinders.
cutting machines, which have a lower feed drive inherent in a multi-purpose.Tools for cutting is applied in such machines automatically.Its slope can occur in any direction.Thanks to this characteristic bending machines of this type, regardless of whether they are single head or dvugolovochnymi, capable of performing complex spatial cuts that are used in the manufacture of translucent structures.
Production cutting machine
in trade are a lot of tools for different price, but you can gather with their hands properly cutting machine from scrap materials with characteristics that are necessary for you.
In the process, you will need these tools and materials: channels, angles, welder, drill, coil, shaft, bearing a pair of electric motor, automatic, start-up circuit, the button layout and electric box for wiring.
Production should start from the frame, the frame, the size of which should be 40 by 60 by 120 centimeters.The material for the frame is the area №25, cut and weld grinder workpiece.Cooked frame, you must be welded to her feet from the corner or the same profile.Weld to the table top channel №10, which serves as a guide and strengthens the frame itself and the entire structure.To him are bolted two uprights.
Then you need from profile pipe sizes 60 to 45 to cook the second frame, which is intended to be mounted on its electric motor and the shaft for cutting stone.Set at the rear of the upper frame plate on which to fasten a motor that has a power of 1.5 kW.
recommended to give preference asynchronous motors, which are considered more reliable and durable.Practice shows that to, homemade cutting machine works correctly, perfect "three thousands," which has a capacity of 2.2 kW and is powered by three-phase network.
Suitable and "the thousand and a half," but recommended the transfer belt transmission rate chosen in such a way that the shaft was observed near 6000 rpm.In the situation of a single-phase supply network, it is necessary to increase engine power by 30% and use the starting and running capacitors.
The design of the shaft and the principle of its attachment can be arbitrary, important to remember that the transmission of the rotation from the electric motor to the shaft to be transmitted via the V-belt.Working shaft bearings, pulleys and a belt drive flanges for better order turner, it is worth to provide a projection of the flange Ø32 mm.
shaft pulley to install and support bearings.They should strengthen in the nests of plates that are on the upper frame.For the location of the wiring, it is desirable to buy a box, attaching it at the bottom of the frame of the cutting machine.The shaft and the engine are fastened with nuts and bolts.
Racks are connected with shaft Ø12 mm clad sleeve.To avoid end motion drive shaft and connected to the sleeve with a minimum clearance sliding fit.This sleeve must be welded yoke of channel №10, which has a size of 800 millimeters, and so that the shoulders were in the ratio of 1 to 3.
stroke rocker limited chain, and from the motor to facilitate the return of the spring is set toexample, from the sports expander.Bracing springs and chains perform with the bolts.The motor is attached to the lower part of the rocker shaft work - in most.Transfer traffic is carried using a belt drive.
to build the circuitry necessary to prepare the case, the cost of which is much cheaper than in the manufacture of their own hands.To connect the machine you need a three-pole automatic start-up, it must be connected to the engine start-up circuit and emergency stop button.The motor is connected via a three-pole machine and a box, emergency stop button - directly.
And finally, remember that the table is made made of planed boards, and in order to equalize the small irregularities - are covered with plywood.Once done cutting machine, you can connect it to the mains and to conduct a test run.Ensure proper operation of the cutting machine, fix the shaft cutting disc and start to work.
