Hand saws are often used in daily decoration, so how is the steel sheet made into a hand saw?

The hand saw is a tool commonly used by carpenters, it is composed of a handle and a saw blade, which is very convenient to use, and can also be replaced with a saw blade for reuse. So how are handsaws made?

Clause. First, a coil of steel sheet is first pulled closer to the punching agent, and then the punching machine cuts out serrations on the steel sheet at a rate of 140 notches per minute, and each serration needs to be cut twice to form. The freshly cut steel sheet is then rolled up with a reel and sent back to the punch to cut out the serrations on the other side.

Next, the steel pieces with serrations are cut on both sides, and the robotic arm pushes it towards the automatic jaws, and the jaws will be bent in opposite directions alternately with serrations, this process is called setting the saws, which can make the hand saw operate smoothly when sawing wood. Then use the airfoil to cut the steel coil into a double-faced steel piece, the reason for the name, because it will cut out two saw blades, and at the same time, the impression will make a hole at one end of the steel sheet, so that it is convenient to add a hand stick in the back.

Clause. Second, the steel sheet is then fed into a cutting machine, and the blade on it will cut it in half diagonally to make two saw blades, and sandbags will polish the edges of the saw blades smooth. The next step is to make a more advanced saw blade machine progressive die.

effect, cut out the serrations and rinse the steel sheet with coolant. This method is more time-consuming, but it can make a good quality hand saw. Then start setting the sawtooth and use the mechanical front to process one blade at a time, rather than the previous long hacksaw.

The roller then passes the blade through an electronic coil, which in just a few seconds reinforces the blade by raising its temperature to 900 degrees Celsius.

Clause. 3. After that, the saw blade will fall from the conveyor belt into a box, and the edge of the heat-treated saw blade will turn black, which is also a sign that it can withstand pressure. The portal then soaks the blade in a pool filled with a transparent protectant, making the surface of the blade smooth and shiny.

After the saw blade dries, the product information is silk-screened on the surface of the saw blade with a foam scraper, and then the saw blade is placed into the infrared oven through the conveyor belt. When the saw blade comes out of the other side of the oven, the worker will put the hard and sleeve on the saw blade, which will prevent the rear installation of the handlebar cut. Before installing the handlebar, the worker first assembles the two handlebar components together, then places them on a rotating machine, and then uses a sealing machine to fuse the two plastic components together to make a handle for the handpiece.

Finally, the worker loads the handle to the saw blade. And the machine rivets it and fixes it, and a hand saw that can easily sawn through wooden blocks is made.

It is to first grind the steel sheet into a sheet with a coarse knife, and then use a tool similar to a tower crane to make the gear of the steel sheet, and then put it on the mill to grind.

After smelting, the steel pieces will be put into a model of a handsaw, which will be made into the shape of a handsaw, and then a frame will be made of rope and wood to fix it.

Just cut the steel sheet to the right length, then make two screw holes in the head of the steel sheet, and fix the steel sheet with screws and a wooden hand saw handle.

1. Saw blades are generally made of metal, carbon and other materials.

2. Bimetal saw blade: a saw blade made of two metal welded rulers, specifically composed of carbon steel saw body and high-speed steel sawtooth. For cutting pipes, solid bodies, wood, plastics and all machinable metals.

Compared with single-metal saw blades, they have higher heat and wear resistance and longer service life.

3. Carbonized sand saw blade: used for cutting glass, hardened steel, stranded optical fiber and ceramic tiles. It is extremely resistant to heat and abrasion, and can cut all other things that the blade or blade cannot cut.

4. High-speed hacksaw blade: used for cutting pipe fittings, solid bodies, wood, plastics and all machinable metals. The hardness of the saw blade is higher than that of other high-speed steels.

It is flexible and suitable for use with a saw frame with low tension. The center of the back of the band is not hardened to avoid cracking during cutting.

5. Carbon steel saw blade: used to cut pipe fittings, solid bodies, wood, plastics and all machinable metals. The cost is low and it is more versatile.

Summary. Dear dear, it's a pleasure to answer your <>

What are the ways to use hacksaws; When installing the saw blade, the direction of its sawtooth should be the direction of forward advancement, as shown in 1. Depending on the requirements, the saw surface can be parallel to the plane of the saw frame or at an angle of 90°. When starting to saw an item, press the left side of ** with the thumbnail of your left hand, hold the saw handle with your right hand, make the saw blade next to your thumb, press the ** on the sawtooth, and <> the saw blade at an appropriate angle (such as about 15°) with the plane of the material

Dear dear, it's a pleasure to answer your <>

What are the aspects of the use of hacksaws; When installing the saw blade, the direction of the sawtooth should be the direction of the forward propulsion, as shown in the first show. Depending on the requirements, the saw surface can be parallel to the plane of the saw frame or at an angle of 90°. When starting to saw an item, press the thumbnail of your left hand on the left side of the Morichun line, hold the saw handle with your right hand, make the saw blade lean against your thumb, press the sawtooth on the **, and <> the saw blade and the material plane at an appropriate angle (such as about 15°).

expand information; When the sawing angle is too large, the sawtooth will be stuck by the edge of the industrial oak piece, which may crack the sawtooth and cause the handsaw to run unstable; If the sawing angle is too small, the number of teeth in contact between the saw blade and the workpiece is too much, it is not easy to cut the artificial part, and the sawing position may be deviated, and the sawing needs to be done many times, and multiple saw marks appear, which will affect the surface quality of the workpiece. Gently push the saw blade to make a small opening, repeat several times, and when the saw edge reaches a certain depth, start to control the normal sawing with both hands, standing position on both feet and arm posture. During normal sawing, the right hand is used to hold the saw handle, which is mainly responsible for pushing and pulling the movement and grasping the direction, and the left hand gently supports the front end of the saw bow, and cooperates with the right hand to straighten the saw and apply a certain amount of pressure downward.

When advancing, the saw blade should be pressurized, and when exiting, do not apply pressure to the saw bow, and the saw body should be gently lifted to reduce the contact between the saw tooth and the sawn surface as much as possible to reduce the wear of the saw tooth, and the speed should be faster than when pushing. The posture and amplitude of each push and pull movement of the body, the speed of sawing should be uniform, stable and rhythmic, and the speed should be moderate. Too fast can easily fatigue the operator and cause the saw blade to overheat and damage quickly.

The general speed is 40 min, the hardness of the material is lower, the direction of the two-handed push should be consistent with the direction of the saw edge, to prevent the bending wheel from being fast, to avoid excessive force to advance and fast forward, to prevent the inference of the saw blade. When the workpiece is about to be sawed, it is necessary to visually see the sawing place, hold the part of the material to be sawed with the left hand, and push the saw with the right hand, the pressure should be small, the propulsion should be slowed down, and the stroke should be small. <>

Summary. The use of hacksaws mainly includes the following aspects: 1. Safe operation; 2. Use the hacksaw correctly; 3. Define sawing parameters; 4. Maintain the hacksaw.

What to look out for when using a micrometer.

When using a micrometer, it should be noted that: 1. Before measuring, carefully check the stool to check the roughness of the smoothing liquid on the processing surface; 2. When tightening, it should be lightly tightened and not too tight, so that the content of the measurement will change in time; 3. Carefully compare the data during operation; 4. The correct accuracy should be selected according to the need.

What are the rules for the safe use of power tools.

The rules for the safe use of power tools mainly include: 1. Check whether the condition of the tool itself is in good condition before operation; 2. Grounding protection wires should be used; 3. Pay attention to safety in the process of use, and do not block the tomb to use Jian Bi Qi too much; 4. Clean the tool and disconnect the power supply after use.

Woodworking saw blades are generally made of carbon tool steel, and there are two commonly used grades: T9 and T10. (i.e. carbon steel with a carbon content of about and ). Woodworking saw blades are used to process wood, which can be divided into left and right teeth and cross-cut teeth according to the tooth shape.

How to use woodworking saw blades.

1.The machine should have good performance without swing;

2.The size of the flange should be the same as 1 3 of the diameter of the saw blade

3.The surface of the flange should be flat and clean, and intersect perpendicular to each other;

4.The gasket should be absolutely vertical;

5.The shaft should be flat and straight, and the tolerance should not exceed H7;

6.The saw blade should be scrubbed clean before installation, and if there is resin sticking to the saw body, it needs to be diluted and wiped out;

7.If the saw blade has a dull feeling, it should be sharpened in time and pay attention to maintaining the original cutting angle of the sawtooth;

8.When grinding, it is not only necessary to choose the right diamond grinding wheel, but also to use coolant;

9.It is recommended that the reaming of the saw blade should not exceed 20 mm of the original hole, otherwise it will cause loss of tension, and the cutting effect of the saw blade will be affected;

10.Each installation must ensure that the flange and gasket are clean and flat;

11.Be careful when grinding the rear angle and saw body, do not operate manually, which will cause the saw tooth to break and the saw body to be unbalanced;

12.When installing the row saw, pay attention to the iron frame and the material table need to be at the same level;

13.Before cutting, check that the saw blade is installed and fastened, and the saw blade is slipping on the shaft.

Saw blade technology Saw blades are specialized in R&D and manufacturing. The substrate for the production of alloy saw blades adopts the unique technology and manufacturing process of weft processing of circular rotary cone roll rolling in the world today, so that the matrix has excellent rigidity and is symmetrically distributed in the center of the circle.

Fabric structure and mechanical properties, stress is evenly distributed in the center of the circle to exert extraordinary rotational straightening ability, cemented carbide saw blade.

It has excellent cutting accuracy. High performance of sintering with advanced technology of high-quality nano-scale tungsten carbide, cobalt and other rare metals.

Can alloy the serration, making the saw blade sharp and durable. The sawing path has good linearity, and the cutting surface is smooth and traceless.

In the case of a carpenter's hand saw, for example, the tendency of the sawtooth (called "saw road" in the row) is applied to the corresponding process. The formation of the saw road is called "left" or "right" by using a metal "office" to tilt the sawtooth to the left or right, and the immovable sawtooth is called "middle". Depending on the application, different saw paths are used.

That is, it is equipped with a variety of saws for different purposes, although it seems to be cumbersome, but it is characterized by the perfection of the process and the ease of operation. The saws that are generally equipped are:

1.Tenon saw, serrations: left, middle, right, middle, ......, use: open tenon. The saw path in the middle of the left and right is more stable and straight when used along the wood grain.

2.Tenon and shoulder saw, serrations: left and right middle ......Purpose: Cut off one or both sides of the tenon to expose the tenon and form a tenon shoulder. The sawing road on the left and right makes the wood cross-sawed and finally cut off without wood thorns and affecting the appearance of the furniture.

3.Transporting saw, saw blade width of about 5 6 mm, serrations: left and right middle ......, use: cutting the inner circle or outer circle of the sawn plate.

The angle of the sawtooth tilt to the left and right of the above three saws should not be too large, and the gap between the sawing out should be narrow to make the saw section smooth. The angle of the serration tilting to the left and right of the next section can be slightly larger, which is more labor-saving and fast to operate

4.Cutting saw, sawtooth: left, right, center......, hence the name implies, is used for the rough cutting of plates and fangs.

The ellipsis after the above sawtooth form indicates the direction of the sawtooth of the entire saw blade, for example: left-center-right-centerleft-centerleft-centerleft-centerleft-centerright-center-right-center.

It is suitable for cutting all kinds of dry softwood, hardwood, fiberboard, MDF, MDF, high-density board, plywood, blockboard, large core board, wood-based board, laminate, particleboard, veneer, fireproof board, melamine ammonia, melamine board, bamboo, bamboo plywood, bamboo flooring, bamboo cutting board, bamboo products, etc.

Woodworking saw blades. When slitting, you can choose the saw blade with less teeth in different outer diameters, the cutting resistance is small, the efficiency is high, and the cutting is smooth, and the saw blade with more teeth in different outer diameters can be selected when the woodworking saw blade is cross-sectioned, with high cutting accuracy and smooth cutting surface. When taking into account the longitudinal cutting and cross-section of woodworking saw blades, you can choose saw blades with moderate teeth in different outer diameters.

MDF and veneer can be selected with ladder flat tooth shape.

The cutting precision is high, the cutting seam is neat, the cutting surface is smooth, the cutting noise is small, the substrate is not deformed, and the cutting service life is long.

Woodworking saw blades are generally made of carbon tool steel, and there are two commonly used grades: T9 and T10. (i.e. carbon steel with a carbon content of about and ). It is used to process wood, and can be divided into left and right teeth and cross-cut teeth according to the tooth shape.
