What are burins made of?

Question 1: What is a burin made of? burin

zànzi

By chiseling, engraving, spinning, chipping the processing of material tools, with a short metal rod, at one end has a sharp edge.

Generally can be divided into flat burin, narrow burin, oil groove burin.

Question 2: Handsaw saw blade, file, burin with what materials are made of carbon tool steel or alloy tool steel.

Hand saw blade is generally used T8Mn or T8MnA,

file is generally used T10 wow T10A,

burin is generally used T11 or T11A.

Problem three: the general repairman with the burin what is the material so good steel and toughness 45 steel on the line is the main edge of the quenching

Problem four: burin How to heat treatment? burin, is a pliers commonly used tools. The material is generally selected T9A or T10A, in front of the edge, the hardness requirements for 56 ~ 60HRC, the handgrip part and the tail part of the hardness requirements, that is, I hope to keep for the annealed state, that is, in the steel hammer under the strong blow with good toughness and plasticity, will not occur in the fragmentation of the collapse of the explosion phenomenon.

The heat treatment method is, after forging annealed burin preliminary open edge forming, the edge of 30 ~ 50mm parts immersed in 780 ~ 800 ℃ salt bath furnace heating - burin to be in the salt bath constantly shaking, so that it is heated thoroughly and uniformly; visual inspection, when the burin temperature is basically the same as the salt bath, remove the burin and quickly Quenched into 10 ~ 15% brine, 1 ~ 2 seconds after the burin will be raised to the surface, burin residual heat back, see the quenched surface will become yellow - red - blue, and quickly 10 ~ 20mm or so continue to be immersed in the brine, so that several times, and finally make it completely cooled down. This burin obtained hardness distribution is, near the edge of the part of the hardness of about 58HRc near, and then to the end of the hardness gradually decreased - in a strong impact both burin cutting ability, but not to the collapse of the edge or fracture.

If there is no salt bath furnace, the use of gas welding flame heating can also be, but in the heating technique should be a little experience and the corresponding heat treatment knowledge.

Practice makes perfect. Handling this type of hand tools, basically based on personal experience, good or bad, the quality varies greatly!

Question 5: What steel is good for a craftsman's burin? Woodworking burin with tool steel to do a good job.

Question six: pliers with a burin can be done with 45 steel? Spring steel is not is said to be the yellow plate just? Know the seniors please do not hesitate to advise. 1, with 45 steel do pliers with burin, the biggest advantage is moderate, too hard chisel can not, but not avalanche edge, with long time.

2, spring steel is often referred to as the plate spring, with this burin feel too meat, but not easily broken. Automobile repair shop to replace the valve plug, valve plug head is a round, the other end of the shot flat on the line, especially suitable for small grooves chiseling.

3, the best material is high-speed steel, is often referred to as sharp steel, hardness and durability can be, my hand pliers sharp steel burin, has been with me for 40 years, is still very good to use. There is also a valve plug made very well.

Question 7: How to quench the burin to increase the hardness Depending on what material your burin is used, if it is a high-carbon carbon steel, then, with the sea quenching on the line. If it is alloy steel, then we have to use quenching oil to quench. It is best to quench only the burin head hardened, the back of the hardness is not too high, so as not to make the burin break.

Question 8: Why should the burin be heat treated? Heat treatment refers to the metal material in the solid state, by means of heating, holding and cooling, change the chemical composition and organization of the material surface or internal, to obtain the required properties of a metal thermal processing technology

is usually said "quenching" "dip fire ", can increase the hardness, so more durable

Question 9: the difference between flat shovels and burins for pliers 10 points Flat shovels made of mild steel, wooden handle, the edge of the store tool steel hardened. Use the ingot to chisel wood.

The burin as a whole is forged with tool steel, hardened edge. Used to chisel iron.

Question 10: burin is a what The clamping technology refers to the use of files, drills, reamers, vise and other tools for machine and equipment equipment and parts production, repair, shaping of the processing and production technology. Commonly used clamping technology includes burring, filing, sawing, drilling, tapping and other aspects of metal processing production technology.

(a) burin

burin refers to the use of burin and other tools to cut the plate, or trim the plate. Burin commonly used in cutting is not easy to cut, but also not suitable for sawing and filing, the thickness of the appropriate metal plate. Burin commonly used tools such as burin, hammer and vise.

The burin is made of hard and not very brittle steel (such as tool steel, spring steel, etc.). Usually used burin has two types, that is, according to the burin width is divided into flat burin and pointed burin. According to the burin plate characteristics, burin size, length points. Burin good or bad, not only depends on the burin material, also depends on the shape of the burin and ruler, usually burin are ground into 50 ° inclination.

Vise is a commonly used clamping tools for clamping processing workpiece, in sawing, filing, shaping, tapping should be used. There are many types of vise, there are table vise, desk vise, flat vise, hand vise, etc. DIY suitable for use with a jaw width of 100 mm can be taken.

The general method of burin is to use the left hand to hold the burin, the right hand to hold the hammer, the burin is aligned with the burin, with the hand hammer hammer burin head. Here are several specific methods of burin.

1. burin plate edge

The plate will be clamped in a vise, so that the burin parallel to the jaws, clamping, with a flat burin diagonal to the work surface, about 35 ° angle of inclination, from the right to burin along the jaws.

2. burin plate

Clamp the plate in the vise, so that the burin parallel to the jaws, with a flat bur right to the plate, from right to left burin a groove line, and then the plate before and after the reciprocating plate folding, so that it breaks. With this method can also be burin broken thicker plate or thicker steel.

3. burin forming

When the plate is directly burin forming, you can first drill a dense hole in the burin to prevent deformation of the plate when burin, and then burin. If the burin contour line for the arc. Should use a pointed burin; for straight lines, should use a flat burin.

The burin is also used for burin plane, burin burr, burin cut rivet head and screw head.

It should be noted that the burin is a rough machining, its machining accuracy is very low. Therefore, burin should be left for finishing margin.

(B) sawing

Sawing refers to the use of hacksaw cutting material. Sawing is suitable for straight line sawing thicker plates or profiles of larger columns, tubes, etc.. Sawing is commonly used to saw metallic materials, but can also be used to saw non-metallic materials.

The main tool used for sawing is a hacksaw, commonly used mainly hand saws. Hand saw on the saw blade length of 300 millimeters, divided into coarse, medium, fine three kinds of teeth, DIY use of medium and fine tooth saw blade is appropriate. Installation of the saw blade should be made so that the teeth are forward, to ensure that the sawing with the thrust work. Saw blade installation should not be too tight or too loose, otherwise it is easy to break the saw teeth or break the saw blade.

Sawing in the first material clamped in a vise, with the right hand holding the handsaw handle, the left hand in the saw blade in the sawing position, to be sawed 2 ~ 3 mm saw groove, and then the left hand holding the saw body, push and pull the handsaw straight, until the saw open.

When sawing with a hand saw, attention should be paid to the full length of the saw blade sawing, at least 2/3 of the full length of the saw should be used, so as to fully utilize the teeth, improve the service life of the saw blade.

In addition, sawing should pay attention to, push the saw when the left hand on the saw body pressure, back to the saw shall not apply force, back to the saw can be slightly lifted saw body, reduce tooth wear.

It should be pointed out that the precision of sawing is not high, usually in the repair or homemade equipment, sawing also needs to be filed and other finishing, so sawing the workpiece should be left to chance.

(C) file

File refers to the file to file the work surface material, so that it reaches the required size, shape and surface finish. File is one of the most important components of the clamping skills. The accuracy of filing is higher than burring and sawing. Hand filing is usually applied to machining small and medium-sized metal parts to finalize their shape. File the use of tools is mainly a file, file file according to the thickness of its file teeth are divided into coarse file, file, fine file and oil file. Coarse file is suitable for processing more than the required precision of the workpiece is low; fine file is suitable for processing less than the required precision of the workpiece is higher. File according to the shape can also be divided into flat file, round file, triangular file, half-round file, etc., for the processing of different shapes of the workpiece. Flat file is suitable for filing plane, round surface, convex surface. Round file is suitable for filing he hole, concave surface, oval surface. In addition for processing small parts, especially when finishing shaping, but also commonly used assorted files.

File processing workpiece, according to the hardness of the workpiece material, the size of the machining allowance and machining accuracy, choose the appropriate file. Such as filing copper, aluminum, plastic parts can choose a coarse file and should not choose a fine file; filing metal surface oxidation layer or casting with sand can only choose a coarse file.

The file is good or bad mainly depends on the file file ...... >>
