葫芦丝的制作The production of cucurbit silkWord文档格式.docx

1、 the simpler instruments, the more difficult to draw quality. A lot of cucurbit lovers want to make their own gourds, but they cant start without any data. I have made a little of my experience in making it. I hope it will help the novice producer.Figure 1Chapter 1 reed productionSection 1 materials

2、 selectionReed is the most critical part of cucurbit, and it is also the most difficult to master. Production of cucurbit reed materials of copper, beryllium or Tin Phosphorus Bronze usually used. After comparing experiments, we should optimize the tin bronze by considering the sound quality, sound

3、quality, sound volume and life expectancy. Copper skin thickness is generally 0.1 mm, but it is best to use 0.2 mm copper skin, after forging, so as to reach 0.1 mm better. Because forging has two advantages: first, it can increase the density of the copper skin and increase the elasticity, thus inc

4、reasing the life of the reed. Second, due to the copper in the production process of rolling, it is bound to form a texture. Forging can eliminate or reduce the texture, thereby improving the quality of sound.Second pieces of cutting materialThe actual size of the reed is 25 mm long and 10 mm wide.

5、Since the copper skin will have an extension in the forging process, the material should be taken into consideration when cutting. 0.2 mm copper skin, just cut out 7 mm wide, the length is generally 80100 mm on it. Note that you must see the texture of the copper skin and cut the length along the te

6、xture.Third quarter forgingWhen forging, it is necessary to choose the flat pier first. It is better to use a flat steel pier machined by the grinder. The hammer is not too big, 100 grams can be. Top hammer should be micro convex edge, do not have sharp edges. Forging must follow the light, uniform,

7、 dense, flat four character tips. Light is every hammer can not be too hard; even that every hammer should be uniform, forging range should be uniform, not light a heavy hammer a hammer, a hammer a hammer is not close to the West; is a hammer - hammer, hammer hammer is overlapping; flat to smooth ca

8、n not be shaken dangling; forging after there will be three situations: the first one is the most perfectly flat ideal. In the second case, the stress is produced and the copper is bent to one side. If you pull your hand to the other side, you will suddenly turn to the other side. Turn back again, a

9、nd so do i. This shows that the central part of the copper sheath is too heavy and can be drawn gently until it is smooth. The third case is that the edges of the copper crust appear wavy, and the entire copper sheath appears soft and inelastic. This shows that the edges of the copper skin are too h

10、eavy to be forged. In contrast to the second case, the center of the copper skin should be lightly hammered until smooth. Sometimes it takes several and several times to achieve leveling requirements. Under normal circumstances, 0.2 mm thick, 7 mm wide copper skin, forged to 910 mm wide, it can reac

11、h 0.1 mm thick.Fourth quarter grindingThe surface of the copper surface is not smooth after forging. It must also be scraped to smooth it. It should be scraped and ground first. When scraping, press the copper skin on the flat pier with a sharp flat blade. One hand press the knife, the other hand tw

12、itch copper skin. Both sides take turns, rotation, until the copper surface has no obvious concave pits. Then use a fine sand paper to clamp the copper skin, with the index finger and thumb pinch tight, the other hand twitch copper skin, the same two turns, until the copper skin is smooth and bright

13、. This copper crust can be cut into a section of 25 millimeters long to be used as the main reed. Vice tube reed can be properly reduced, usually 1720 mm long, 78 mm wide.The Fifth Festival OpeningOpen, is in the prepared copper out with vibration of the vocal languette, the key process is made of r

14、eed.This process must be more careful, can not have the slightest negligence, otherwise it will come to naught. First, prepare a flat, plastic （1020 mm） thickness, plexiglass or electric board, with 801 glue to stick the copper onto the board. Then, by drawing a needle in the copper skin to draw the

15、 main position. The size of the main charge is 17 mm long, 0.70.8 mm wide tongue, tongue base width 2.5 mm. The size of the main auxiliary pipe is 10 mm long, 0.60.7 mm wide tongue, tongue 11.5 mm wide. According to the drawing of the line with a sharp knife, carved languette. Can use steel ruler co

16、rnered, so as not to go. At the moment, the lower part of the tongue is broken off by the lower blade at the tip of the tongue. Then from the root under the knife, carved a long tongue, both sides take turns. Dont press the knife too hard. Each knife is engraved with a few more knives until it is ca

17、rved. Finally, the sword with the copper skin down from the board, cutting is completed.Sixth piece retouchingFor a good spring, it needs trimming. Sometimes, in the process of cutting some parts not carved through, you need to make time to the main frame and spring completely stripped. At the same

18、time, there are a lot of burrs that have to be opened and must be removed. Do the gap is uniform, tongue, tight and do not touch the main frame, move up and down freely. Finally, smooth the reed with fine sandpaper. Later, you can install it to the supervisor and debug it. The tuning of the reed wil

19、l be further introduced in later articles.If there is any inappropriate, I would like to ask you to correct me.The renewal process of silk gourdThe second chapter, gourd processingChoose the gourd in the first sectionTo make Hulusi, gourd is essential. Choose what kind of gourd, for cucurbit silk ap

20、pearance and internal quality, have great influence. First of all, different tunes of cucurbit silk have different requirements on the size of gourds. In general, small C, D adjustable hoist lower diameter is 75 mm; B flat, lower hoist A diameter is 90 mm; F, G adjustable hoist lower diameter is 100

21、 mm; other keys can refer to the above rules selection. Require smooth surface, no scars, scratches and mildew, the color is consistent, preferably gold yellow. Shape Zhou Zheng, symmetry, from both sides of the straight, both sides should be symmetrical, not askew. With a nail hammer, the sound sho

22、uld be crisp and bright. This kind of gourd can be used to make cucurbit silk.Second external processingIf you choose a rough processed gourd, you can omit the process of removing epidermis. Otherwise, the gourd should be soaked in warm water for 30 minutes, and then use a bamboo knife to scrape the

23、 gourd skin. Scraping the skin, it is best to follow the gourd up and down the direction of scraping, requiring uniform scraping, can not be omitted. Dry after scraping and grind with fine sandpaper. Next, make sure the front and the right sides of the gourd are well drawn, draw the center line on t

24、he front and ask to cross the center of the bottom. Next, draw the side center line at the bottom and cross over the front center line. Outline the interface of the intubation line on the cross line, and drill the hole of the intubation interface according to the contour line. Interface requirements

25、 and intubation are tightly combined with not have too big gap, otherwise the adhesion is not easy to secure and easy to leak. Finally, the pattern is stamped on the front and the gourd is machined.If the article is to help you, please. Later on. Ha-ha！Send gourd silk technologyThird sections of int

26、ernal processingAfter the external processing of the gourd, it can be processed internally. A small spoon shaped tool made of curved wire 10 in advance. The front end is flat and then the edge is cut into the edge of the knife. Use it through the cannula interface mounting hole, the gourd flesh cut

27、net. We must dig clean, has been swept into the xylem, not a gourd flesh remaining, otherwise, will affect the quality and volume, especially the volume. Cut after the milk white glue diluted in water, the inner surface coating. Coating should not be too thick, must be uniform. Clean the excess glue

28、 and let it dry.The third chapter of bamboo processingThe bamboo material made of Hulusi has many kinds, such as bamboo, bamboo, bamboo and Mianzhu, but it is best to zizhu. The south by Yunnan zizhu,The North should adopt Fujian zizhu. Because Yunnan Zizhu in the north, due to climate, easy to crac

29、k. Fujian Zizhu is more adapted to the climate, not easy to crack. Hulusi different tune, the bamboo diameter is different. This aspect is to take into account the size and size of the gourd, the appearance of relatively beautiful. More importantly, from pronunciation, tone, volume and so on. Small

30、C, D tune director, outer diameter of 1718 mm, length of about 300 mm. The outer diameter of the vice pipe is 1314 mm, the length is about 250 millimeters. The outer diameter of the head of B and A is 1820 mm, and the length is about 350 millimeters. The outer diameter of the auxiliary pipe is 1415 millimeters, the length is about 270 millimeters; the big F and G are in charge of the outer diameter of 2224 mm, and the length is about 400 millimeters. The outer diameter of the secondary pipe is 1617 mm, and the length is about 350 millimeters. All the bamboo are required at both ends
