Embodiment Construction

[0031] see figure 1 , figure 1 It is a schematic diagram of the overall structure of the portable thermite welding shaft welding device of the present invention. Depend on figure 1 It can be seen that the portable thermite welding shaft welding device of the present invention includes a broken shaft fixer 1, a mold 3 and a self-propagating welding pot 2;

[0032] The structure of the broken shaft fixer 1 is as follows: figure 2 As shown, it includes a base 1.3, a supporter 1.4, a baffle 1.2 and a ring holder 1.1, and the base is mainly used to fix the supporter and the baffle. There is a rectangular slot on the base for the supporter 1.4 to slide or be fixed on it, so as to adjust the gap between the two broken shafts. There are multiple supporters 1.4, and the multiple supporters 1.4 are divided into two groups, one on the left and one on the other. , the baffle plate 1.2 is fixedly arranged on the base 1.3, and placed on the left side of the supporter 1.4, the ring hold...

Abstract

The invention relates to a method for welding a shaft of a portable exothermic welding shaft welder. The problem of fast welding and repairing of broken shafts of military equipments and civilian vehicles is solved. The shaft welder comprises a broken shaft fixer (1), a die (3) and a self-propagating tinker (2), wherein the broken shaft fixer (1) comprises a base (1.3), a supporter (1.4), a baffle plate (1.2) and a ring fixer (1.1); the self-propagating tinker (2) comprises a steel pot (2.5); a bottom refractory brick (2.4) and an upper refractory brick (2.2) are arranged on lining of the steel pot (2.5); a thermit welding flux and an igniter (2.6) are arranged inside the upper refractory brick (2.2); and the thermit welding flux and the igniter (2.6) are pressed together as a whole. The method comprises the following processing steps: treating the surface; filling a die, loading the thermit welding flux and the igniter, casting and pressurizing, stripping the die and polishing. According to the invention, shaft parts of battle-scarred tanks are fast welded and repaired by utilizing an exothermic welding technology, particularly, proper pressure is exerted in the welding process, so that metallographic structure of a welding area is obviously improved and the welding strength is improved.

Description

technical field [0001] The invention relates to an aluminothermic shaft welding device and a shaft welding method thereof. It is mainly used to solve the problem of rapid welding repair of broken shafts of military equipment and civilian vehicles. It belongs to the technical field of broken shaft aluminothermic welding. Background technique [0002] At present, there are more than one hundred shaft parts on tanks and broken shaft vehicles, which are responsible for force transmission, damping, support, fixing and other functions. In actual application or in combat, once damaged, it is generally replaced, and the combat effectiveness will be affected if there are no spare parts. [0003] Aluminothermic welding is a new maintenance technology that has emerged rapidly in recent years. It can be operated by a single soldier on the battlefield without electricity or gas. It has been successfully applied to rail welding. Contents of the invention [0004] The object of the pr...
