Description

Aluminum bus welding die with fume collecting hood Technical Field The utility model relates to the technical field of repairing defects on the surface of an aluminum bus, in particular to an aluminum bus welding mold with a fume collecting hood. Background The aluminum bus is often damaged accidentally in production, and the welding aluminum bus is mainly used for welding by gas welding, but the welding method is only suitable for welding thin plates and has low efficiency, has limitation in practical application and can only be used for local repair of aluminum soft belts, and the welding method is used for repairing by arc welding. However, due to the existence of a strong magnetic field, when the welding is started, sparks are splashed everywhere to form no arc column, and the phenomena of magnetic bias blowing and splashing of the electric arc are serious, so that the labor intensity and the construction difficulty are increased, the effective welding cannot be performed, the aluminum bus is welded through the self-propagating reaction, and the metal solution is input to the defect position of the surface of the aluminum bus, so that the problems can be avoided. When the aluminum bus is welded through the self-propagating reaction, the aluminum bus can be subjected to severe heat release through the thermit reaction in the crucible, so that a metal solution is generated, and great smoke and fire light are generated, and even splashed out, so that the surrounding staff can be disturbed and injured, and a certain safety risk exists. Disclosure of utility model The utility model aims to provide an aluminum bus welding die with a fume collecting hood, which is used for solving the problems in the background technology. The aluminum bus welding mould with the fume collecting hood comprises an aluminum bus to be welded, graphite plates fixed on the periphery of the aluminum bus to be welded and a crucible, wherein the number of the graphite plates is four, the four graphite plates are respectively positioned at the front, back, left and right sides of the aluminum bus to be welded, the graphite plates at the front and back sides are tightly fixed with the aluminum bus to be welded, and limiting mechanisms are arranged on the outer sides of the left and right graphite plates; The limiting mechanism comprises a fixed seat and a screw rod, and the end part of the screw rod passes through the fixed seat and then butts against graphite plates positioned on the left side and the right side of the aluminum bus to be welded; The crucible is of a cylindrical tank structure, the bottom surface of an internal accommodating cavity of the crucible is of a concave shape, a self-fluxing gasket is arranged in the center of the concave surface of the crucible, a flow passage port communicated with the bottom end of the self-fluxing gasket is connected with a flow guide pipe, and the end of the flow guide pipe is contacted with the surface defect of the aluminum bus to be welded after passing through a graphite plate on the front surface of the aluminum bus to be welded; The top end of crucible is provided with keeps off lid mechanism, it includes the collection petticoat pipe of openly opening structure to keep off lid mechanism, the collection petticoat pipe is for having the drum structure of openly breach, has the arc to keep off the lid through spout slidable mounting on the inner wall of collection petticoat pipe, be provided with the cylinder arch on the surface of arc keeps off the lid, install the suction fan on the top cap of collection petticoat pipe, the top end of suction fan is connected with the exhaust column. Preferably, a filter screen is arranged at the position where the inner top surface of the fume collecting hood is communicated with the suction fan, the fume collecting hood is fixedly sleeved on the crucible through threads, and the suction fan is externally connected with a power supply. Preferably, the flow guide pipe is obliquely arranged from top to bottom. Preferably, the arc-shaped blocking cover is positioned at the front opening of the fume collecting hood. Advantageous effects The utility model provides an aluminum bus welding die with a fume collecting hood, which has the following beneficial effects: In the scheme, the fume collecting hood with the front opening structure is arranged on the crucible as the cover blocking mechanism, the arc cover is slidably arranged in the fume collecting hood, the top cover of the fume collecting hood is provided with the suction fan, the top end part of the suction fan is connected with the exhaust pipe, and the whole fume collecting hood is fixedly sleeved with the crucible through threads, so that the fume collecting hood is convenient to clean after being disassembled, and the impression of harm to surrounding staff caused by a large amount of smoke and fire in the aluminothermic reaction process in the crucible is avoided; After the metal solution gene
