It is often necessary to cut into pieces large sheets of metal, pieces breaking off from them, cutting grooves and channels, removing the solid crust, etc.To accomplish all of these procedures use different methods.
How to cut the metal at home
Home metal cutting is carried out using the grip, hammer and chisel.The last tool consists of three parts - the shock, the middle and working.The working part is formed as a wedge for an average instrument holds master drum part has a rounded end and tapers upward.Chisels used for the production of carbon steel.Before you start cutting applied to the workpiece at the place of the future risks of cut.The sheet was then inserted into the vise so that risks were visible.The first blow chisel applied horizontally, all subsequent - at an angle of 25-30 degrees.Felling of metal sheet - a rather complicated and time-consuming procedure, so the above method is only suitable for processing small batches of material.In an industrial scale are more advanced automated methods.
felling of large quantities of metal
often in small workshops, and sometimes the enterprises for razrubaniya metal sheets used pneumatic chipping hammer.Work holding it with both hands, guiding the chisel exactly as planned cutting line.Felling of metal in a way different and less labor is faster than manual.Pnevmomolotok can work both on conventional network or from the compressor.
cutting metal sheets using a guillotine
In large enterprises, if there is a need in the treatment of very large quantities of metal, use a special tool significantly reduces the time of surgery, often making the process fully automated.This guillotine.Felling of metal guillotine is made from the entire length of the sheet.Before working metal blank is fixed to a horizontal support beam using the device.Then he induced a sharp knife of the guillotine.The sheet is cut in one motion of the knife.This incision turns out very smooth.
Advantages and disadvantages of a guillotine method
Felling of metal using a guillotine has many advantages such as:
- high speed;
- precision cutting;
- high quality (the seam does not require further processing);
- efficiency (low loss of metal).
However, this method has some drawbacks:
- workpiece size is limited;
- steel with a high content of silicon, titanium and chromium in this manner are not cut;
- relatively high cost of cutting;
- narrow range of thickness of the metal;
- restrictions in terms of working temperature (figure depends on the characteristics of the specific model of the guillotine).
electrical addition of guillotines in enterprises often used hand.Their convenience is primarily in the fact that the use of such tools can be in any conditions, even where there is no electricity.
Felling of metal - a very difficult, demanding attention and care process.With the use of modern devices intended for this purpose, you can significantly reduce labor costs, speed up processing and make the results of higher quality.
