Pyrography tool: (1) electric soldering iron or soldering iron bar. The power of electric soldering iron is generally150-300 W. The head type should be straight and bent, and it can be selected according to the needs when using. If there is no power supply, you can use a soldering iron to make your head square, round, flat or triangular. When pyrography, 3-4 soldering iron bars can be inserted into the furnace for heating at the same time and used alternately. (2) voltage regulator. Used to adjust the voltage level, so that the electric soldering iron can get proper heat. (3) planing and sanding. So as to carry out fine processing when encountering uneven wood and bamboo surfaces. (4) varnish and brush. It is used to draw the cover of pyrography.
The main process of making pyrography:
First, material selection. Tiles commonly used in pyrography are basswood board and basswood plywood, which require white color, fine texture and smooth and flat surface. If it is made by hanging pyrography, you can choose a diagonal saw with fine and beautiful wood grain to make the wood surface oval and then saw it into a square.
Two. Design. We should design various pictures according to the texture, texture, size and use of the selected raw materials. It's best to draw a sketch on the raw material or paper with a pencil first, so that we can be sure when ironing.
3. perm. First, the electric soldering iron is electrified and heated, or the soldering iron rod is put into the furnace and then smeared with it. When ironing, you should master the temperature, write accurately, and the speed and depth should be appropriate. Hook, roll, rub, point, stand before, side before, back before, etc., can make the "pen" touch cadence. Make the focal line appear in five different colors: focal, dry, moist, thick and light, forming a natural, harmonious and exquisite picture. When writing, you should avoid hesitation and hesitation, and avoid leaving a discordant brand on the picture, which is difficult to modify.
Fourth, the title. Pyrography generally pays attention to the title, and the seal should be stamped with the charm of the stone. Some seals can also be painted scarlet.
Fifth, cover the paint. Paint varnish on the painting with a brush to make it durable. Some of them should be appreciated as art, with borders, substrates and hooks. About pyrography tools. At first, it relied on a sharp fire stick. Later, people used carbon-based iron pens to burn carbon-based, and then they could continue to burn simple pictures on the wooden comb with the tip of the iron pen. This is a great progress in pyrography tools, but carrying a pen is cumbersome and inconvenient to operate. Until about 1960, Changzhou Comb Factory began to wind the needle with electric heating wire, and then made products with electric heating needle, which was a major reform of pyrography tools. I made many pyrography with this electronic pen. However, when using this equipment, it is not convenient to adjust the voltage and current intensity. In May 2002, according to the needs of making more works, with the help of experienced physics teachers and electronic engineering technicians, the voltage regulating transformer device of soldering iron was improved, and a very safe transformer material with low voltage and high current intensity was made by using modern electronic technology, and the voltage and current intensity can be adjusted by the knob according to the needs of pyrography (generally, the voltage is controlled between 8 volts and 15 volts) to ensure the required stylus temperature. With such a device, the operation is much more convenient. It greatly reduces the burning of the electric heating wire and prolongs the service life of the electric branding pen. At the same time, the metalworking technician improved the structure of the electrocautery pen. In addition to different shapes of electrocautery pens, the back of the pen head is also provided with a heat sink, so that when the pen head is electrified and heated, the pen holder will not feel hot. Pyrography tools can also be improved, for example, to complete large clouds or large areas of unified colors, you can try gasoline or diesel flamethrowers; For example, there is now a computer-controlled pyrograph machine. It can make pictures on small crafts,
