A steel-aluminum connection mold

Abstract

The invention discloses a steel-aluminum connecting mold and an application method thereof. The steel-aluminum connecting mold comprises a bottom mold plate (1), bottom mold plate grooves (1-1), two lateral mold plates (2), two side mold plates (3), a top mold plate (4), a convex mold block (5), transverse pull rods (6), nuts (7) and vertical pull rods (8). The bottoms of the lateral mold plates (2) are inserted into the bottom mold plate grooves (1-1). The two side mold plates (3) are inserted between the two lateral mold plates (2). The two lateral mold plates (2) are fixed by the corresponding multiple transverse pull rods (6) and nuts (7). The top mold plate (4) and the bottom mold plate (1) are fixed by the corresponding multiple vertical pull rods (8) and nuts (7). One end of the topmold plate (4) and one lateral mold plate (2) are closed, an opening (5-1) is formed between the other end of the top mold plate (4) and the other lateral mold plate (2), and the convex mold block (5) can penetrate the opening (5-1). The steel-aluminum connecting mold has the advantages that mold plate machining is simple, and assembling is simple, convenient and efficient; a steel mold block andaluminum are connected tightly, strength is high, and the rigid structure is good; the connecting part load bearing force is large; and the hollow steel mold block is filled with the aluminum, and the problem of large resistance of steel-aluminum connection is effectively solved.

Description

technical field [0001] The invention relates to a steel-aluminum connection mold. Background technique [0002] In the production of electrolytic aluminum, the connection between the aluminum guide rod and the steel claw has always been a difficult problem. The current passing between the aluminum guide rod and the steel claw is large (thousands of amperes to tens of thousands of amperes), and it must also bear a large weight (the steel claw and the graphite block weigh more than 1 ton), so the strength of the joint surface of the connecting piece is required to be high. , the resistance should be small. [0003] Aluminum and steel cannot be directly connected by electric (gas) welding. At present, the connection between the aluminum guide rod and the steel claw is commonly used for explosive welding, but it is not ideal in actual production. When explosive welding is performed from the aluminum conductive rod to the steel claw It can only be welded around the periphery of...

AI Technical Summary

Problems solved by technology

[0004] Therefore, steel-aluminum explosive welding has the following problems: (1) The effective welding cross-sectional area is small; (2) The composition of the weld is not uniform; (3) The welding deformation is large; (4) The welding strength is low and the bearing capacity is low. Small, short service life; (5) produce sound, light, and gas pollution; (6) have safety problems
