Problems solved by technology

[0003] Since the fusion welding of tin-copper alloy and steel mainly has problems such as difficult fusion on the copper side, thermal cracks and performance degradation of the base metal, the main problem of its connection is that its physical properties do not match, the melting point, thermal conductivity and linear expansion coefficient of the two The difference is large, which leads to large welding stress and deformation. Due to the presence of alloying elements or harmful impurity elements in the seam area, it is easy to form eutectic eutectic crystals at the grain boundary, resulting in thermal cracks. penetrating crack
Therefore, when the blade of the bronze sword is inlaid with medium carbon steel to make the sword, cracks often appear on the blade surface, which affects its quality.

Embodiment approach 1

[0009] Embodiment 1: see figure 1 First, the rough billet of the sword is made of tin bronze alloy in the form of a traditional sword. A groove is opened along the blade line at the blade of the sword. Then the manganese steel sheet is inserted into the groove, and the steel sheet is wrapped by bronze. Expose one side of the steel sheet, insert the steel sheet into the groove on the bronze sword blank, and then use acetylene oxygen welding to melt the bronze at the contact with the steel sheet to the steel sheet, so that the surface of the steel sheet is welded to the bronze, and then , Grind the blank of the finished steel sheet and bronze fusion, grind the steel blade on the edge of the knife, and finally heat the sword body, and then install the handle and other components to complete the production of the bronze sword.

Embodiment approach 2

[0010] Embodiment 2: Using tin-bronze alloy to make the rough blank of the sword in the form of a traditional big sword, a groove is opened along the blade line at the blade, and then the stainless steel sheet is inserted into the groove, and the stainless steel sheet is wrapped by bronze to expose it. On one side of the steel sheet, after inserting the steel sheet into the groove on the rough billet of the bronze sword, acetylene oxygen welding is used to melt the bronze at the contact with the steel sheet to the stainless steel sheet, so that the surface of the stainless steel sheet is welded to the bronze, and then, Grind the knife blank after the stainless steel sheet and the bronze are welded, grind the steel blade on the edge of the knife, and finally heat the sword body, and then install the handle and other parts to complete the production of the bronze knife.

Embodiment approach 3

[0011] Embodiment 3: First, forge the medium carbon steel into a strip of 4 cm wide and 60 cm (the shape of the blade of the sword), and drill small holes with a diameter of 1 cm every 4 cm in the middle. Sprinkle borax on the surface of the medium carbon steel strip and place it in the mold for later use.

[0012] After the tin bronze alloy is melted, it is poured into a mold with medium carbon steel strips, and allowed to cool and solidify, so that both sides of the steel sheet are wrapped by the tin bronze melt. After cooling, the steel sheet produced in the welding process The part that is not fused with the bronze is then melted on the steel sheet by acetylene oxygen welding. Then, the knife blank that has been welded between the stainless steel sheet and the bronze is polished, and the steel blade is sharpened on the blade, and finally the sword body Heat treatment, then install the handle and other parts to complete the production of the bronze sword.

Abstract

The invention discloses a manufacturing method of a bronze sword, which comprises the forming and forging process of the blade body of the sword. Firstly, a rough blank of the sword is made of bronze material according to the form of the sword to be forged, and a line is opened along the edge line of the sword. groove, and then wrap the steel sheet with bronze in the manganese steel sheet. It is melted onto the steel sheet, so that the surface of the steel sheet and the bronze are welded, and then the steel sheet and the bronze fused blade are polished, and the steel blade is ground on the edge of the blade, and finally the sword is heat-treated to complete the production of the bronze sword. Because the present invention realizes the combination of bronze and steel sheet through the bronze welding method, the bronze sword not only has the antique characteristics of bronze sword, but also makes the bronze sword have the sharp feature of steel knife, and solves the defect that the bronze sword is easy to break.

Description

Technical field [0001] The invention relates to the technical field of the production of swords, in particular to a method for manufacturing a bronze sword. Background technique [0002] The sword is a cold weapon commonly used in ancient times. In the Bronze Age, human society began to use bronze to make swords as weapons. This bronze is actually a tin-copper alloy. With the progress of the times, this bronze weapon has withdrawn from the weapon market. Because swords made of bronze have more ornate colors, they are often welcomed by the market as an artistic tool. However, because bronze is an alloy of copper and zinc, its hardness is low, so swords made of this material can often only be used for art collections and cannot be practical. If it is to be used as a fruit cutter or other cutting tools, it lacks practicality due to its weak edge. Therefore, in order to solve this defect, the makers of bronze swords often use the method of inserting manganese steel into the blade...
