Do you know how pencil sharpeners are made? What are the automatic production methods of pencil sharpeners? This thing, scientifically known as a pencil sharpener, is a must-have stationery for elementary school students, and with just a few easy turns, you can sharpen the tip of a pencil. Let's take a look.

Clause. 1. The most important part of the production of a pencil sharpener is the blade, and the material used is generally high-carbon steel.

The steel coil is cut out by the horning machine, and then fed into the punching machine, the initial shape of the blade is cut, and the assembly hole is punched in the blade**, and the logo is printed at the same time. With the advent of modern machine tools, the coil blade can produce more than 100,000 blades per hour, and the efficiency is tens of thousands of times faster than 150 years ago. The finished cutting blade is to be fed into the oven at 815 degrees Celsius.

At high temperatures, the high-carbon steel is rotated and heated for 20 minutes, and the heated blade is taken out and cooled in oil, at which point the blade loses its luster but becomes harder.

Clause. 2. The cooled blade will be put into the hollow drum for oil dragging. Next is polishing, generally using a mixture of dry corn and polishing paste, through a rapid rotation of the roller, the blade is stirred for six hours, the blade slowly regains its shine, the blade is threaded with a metal rod, and then all the blades are opened, and the blade is made.

The next step is to make the shell of the pencil sharpener, the main material used is usually several magnesium strips, which are cut to a suitable length and then printed with a printer. Next is the opening, use a conical drill bit to drill a pencil-sized hole in the main body, and then drill another hole in the top of the main body, which is where the blade is fixed.

Clause. 3. Then soak the main body of the pencil sharpener with five chemical solutions to make the main body of the pencil sharpener brighter, and then remove the residue left by the chemical solution through the dryer, and then install the blade. With a special machine that screws the blade and body, these schoolchildren's favorite pencil sharpeners are ready.

That's all there is to the automatic production of pencil sharpeners.

It is necessary to choose the right blade, so that it can be better made, and in general, it is high carbon and high carbon to be fixed for use.

The most important thing in the production of pencil sharpeners is the blade, which is made of high-carbon steel, which is coiled through a keratin machine and then fed into a diaphragm cutter to cut out the shape of the blade, and the blade is assembled and punched with a mark. Pencil sharpener automation uses machines to make it, which can reduce the use of a lot of manual labor.

It must be made by assembly lines and machines. It is necessary to place all the parts on the assembly line first, and then the assembly line is finally assembled through a step-by-step operation, and then packaged, so that the production process is completed.

I know that it is to use CNC machine tools or mechanical processing and artificial processing, and at present, there are various manufacturing methods.

For the production of the pencil sharpener, first of all, there is some cost of plastic, and some blades are needed, so it uses this physical mechanical movement throughout the process.

Prepare the pencil: Pick up the pencil that needs to be sharpened.

Open the pencil sharpener: If you're using a handheld pencil sharpener, there will usually be a turning edge and a container for the chips. Open the edge of the pencil sharpener so that the pencil can be inserted.

Insert the pencil: Insert the pencil that needs to be sharpened into the edge of the pencil sharpener. Make sure that the insertion is at the right depth, usually a little bit of the lead core is exposed. Clean the pencil sharpener: If you're using a pencil sharpener that has a crumb container, empty it regularly so you can keep it clean.

The child's pencil sharpener is always lost, and with this method, there is no need to throw pencil scraps around.

From the perspective of materials, there are plastic, wood, metal, ceramic and so on. Most pencil sharpeners are made of plastic, and this type of pencil sharpener is common. Pencil sharpeners made of ceramic are relatively rare.

A pencil sharpener is a tool for sharpening pencils that can be made into various shapes. The pencil sharpener series is made of high-quality plastic, with a fashionable and delicate shape, which can be used as a decoration.
