Method for processing yak horn comb blank

Abstract

The invention discloses a method for processing an yak horn comb blank, which comprises the following steps: (1) preparing the primary yak horn comb blank: choosing an yak horn with the shape and thickness suitable for making a comb, cutting off leftover materials, making the yak horn into the primary yak horn comb blank by cutting the yak horn from the middle part along the direction extending towards the ox-head from the tip of the yak horn, and storing for later use; (2) heating and softening: putting the made primary yak horn comb blank into a paraffin liquid which is melted and is at 120-150 DEG C, and heating and softening for 2-3 minutes; and (3) preparing the yak horn comb blank: putting the softened primary yak horn comb blank into a pressing machine for flattening and straightening the primary yak horn comb blank, and obtaining the yak horn comb blank after cooling the flattened and straightened primary yak horn comb blank. By using the method provided by the invention, the phenomenon that a large amount of water is sucked in the process of preparing the yak horn comb blank is completely eradicated, the original organic matters of the raw materials are protected well, the yak horn comb blank cannot be easily carbonized in the preparation process, the prepared product is difficult to deform and is not brittle, the yak horn comb blank can be produced in batch, and the quality and the service life of the yak horn comb blank are promoted.

Description

technical field [0001] The invention relates to a processing method of a yak horn comb blank, in particular to a method for softening a yak horn comb blank placed therein by heating paraffin wax with electric control. Background technique [0002] Since ancient times, my country has produced horn combs (buffalo horn combs) for thousands of years. However, an indispensable process for making horn combs is to straighten and flatten the horns (the initial blanks of horn combs). The general method is to bake the horn comb blank with firewood and charcoal fire. The main purpose is to dry the moisture in the horn comb blank; In recent years, people have also begun to bake the horns directly on the electric stove to soften and flatten them after drying, or bake them in an electric oven, or heat them up in a far-infrared oven to soften them and then flatten them. All there is weak point in above these methods: the one, feel operation by experience entirely, and horn comb blank is o...

AI Technical Summary

Problems solved by technology

There are deficiencies in the above methods: one is to operate entirely by experience, and the horn comb blanks are often heated unevenly, commonly known as soft and old.

However, in practice, this method will lead to a series of problems. Problem 1: Since the material density of yak is several times higher than that of other horns, and the hardness is relatively high, the moisture content and organic structure of yak horns in different regions are quite different. , the storage time is also different, and the patent drying the yak horn comb blank at 60-70 degrees can easily cause the material to crack, which is not conducive to the production of combs

Question 2: Heating and softening the raw material of animal horn combs is an extremely critical and important technology for making animal horn combs, and boiling yak horns has always been a taboo method for making yak horn combs. The methods of making combs from ancient times to the present include open fire, The direct heating method of the electric furnace and the indirect heating method of the far-infrared ray were also called treasures from the fire by the ancients; in this patent, it is impossible to press the yak horn comb blank by heating the blank in water at 80-100 degrees to soften it, and boiling it in water When yak horns are used, a large amount of water will penetrate into the yak horns, and the yak horns will not soften, and will crack when exposed to air drying. The above facts and practices have proved that heating water at 80-100 degrees to soften and flatten the yak horn comb blank is Impossible

Usually, the pressing force used to manufacture yak horn combs and other animal horn combs is less than 20 tons, but the patented method uses 25 tons to 35 tons of pressure to press the unsoftened yak horn comb blank, which can only crush the yak horn comb blank tearing, resulting in the scrapping of the billet
