Embodiment 1

[0031]SeeFigure 1 to Figure 3In one embodiment, a special-shaped copper strip top-drawing continuous casting mold includes a graphite mold 1, a cooler, and a seal. among them,

[0032]The cooler includes a shell 6, a middle tank 4, an inner tank 3, a water inlet unit 8, and a water outlet unit 7. The inner liner 3 passes through the outer shell 6, and the head end of the inner liner 3 is provided with a connecting groove, and the notch of the connecting groove is connected with the outer shell 6. The tail end of the inner bladder 3 is connected to the tail end of the housing 6 for connecting external devices. The middle bladder 4 is arranged between the inner bladder 3 and the outer shell 6. The middle bladder 4 cooperates with the inner bladder 3 to form a cooling liquid cavity, the middle bladder 4 cooperates with the outer shell 6 to form a liquid outlet cavity, and the cooling liquid cavity communicates with the liquid outlet cavity. The water inlet unit 8 penetrates the housing 6 ...

Embodiment 2

[0047]A special-shaped copper strip production equipment includes the special-shaped copper strip upward continuous casting mold of the first embodiment. By arranging the inner bladder 3 and the outer bladder in the shell 6 of the crystallizer, and cooperate to form a connected cooling liquid cavity and a liquid outlet cavity, and setting the liquid inlet and the liquid outlet so that the cooling liquid enters and exits from the cooling liquid cavity The liquid cavity flows out and then circulates after cooling. The special-shaped copper strip in the inner tank 3 is cooled during the flow in the two cavities. The cooling liquid has a large contact area with the inner tank 3 to ensure the cooling speed of the special-shaped copper strip to ensure the copper strip The production quality improves the qualification rate of special-shaped copper strips.

Abstract

The invention discloses a special-shaped copper strip up-drawing continuous casting crystallizer and special-shaped copper strip production equipment. An inner container and an outer container are arranged in a shell of the crystallizer and form a cooling liquid cavity and a liquid outlet cavity which communicate with each other in cooperation, and a liquid inlet and a liquid outlet are formed, sothat cooling liquid enters from the cooling liquid cavity, flows out from the liquid outlet cavity, and then circulates after being cooled. In the flowing process in the two cavities, a special-shaped copper strip in the inner container is cooled, the contact area of the cooling liquid and the inner container is large, the cooling speed of the special-shaped copper strip is guaranteed, the production quality of the copper strip is guaranteed, and the percent of pass of the special-shaped copper strip is increased.

Description

Technical field[0001]The invention belongs to the technical field of copper strip production, and in particular relates to a special-shaped copper strip upward continuous casting mold and special-shaped copper strip production equipment.Background technique[0002]High-precision special-shaped copper strip is an important raw material for the manufacture of triodes. It needs a high-precision special-shaped copper strip with a certain degree of resistance to pressure, not easy to bend, electroplating, spot welding and high-temperature packaging. The current production methods for special-shaped copper strips include forging hammer method and upward drawing method. The forging hammer method makes the special-shaped copper strip gradually formed by rapid forging. The special-shaped copper strip produced by this method has a precise density, but the material size cannot be effectively controlled, and the cost is high. There are many processes for the up-drawing method: the upper-drawing p...
