Problems solved by technology
[0002] At present, the production of battery steel shells uses progressive continuous ordinary molds, which are straight up and down, and the mold is punched in a single way. Only ordinary straight-walled steel shells can be produced. The steel shells produced have large limitations and thick walls, resulting in small capacity of the steel shells. Unable to meet the basic requirements of the existing high-capacity lithium battery steel case

Embodiment Construction
[0012] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0013] Such as figure 1 Shown, a kind of one-time composite mould, comprises C mold 1, and C mold top is provided with C mold upper die punch core 2 correspondingly, and C mold comprises inner mold 11 and one-time composite outer mold 12, and one-time composite outer mold 12 sockets Become combined type lower mold on inner mold 11. The primary composite outer mold is in the shape of a cylinder, a convex ring is provided on the outer side of the bottom of the primary composite outer mold, an expansion port is provided on the inner side of the bottom, and a snap ring inclined inward is arranged on the inner side of the top of the primary composite outer mold. The inn...

The invention discloses a one-step composite die which comprises a C die. An upper C die core is arranged above the C die and corresponds to the same, the C die comprises an inner die and a one-step composite outer die, and the one-step composite outer die sleeves the inner die to form a combined lower die. The one-step composite outer die is cylindrical, a convex ring is arranged on the outer side of the bottom of the one-step composite outer die, an expansion port is formed in the inner side of the bottom of the one-step composite outer die, and an inward inclined clamp ring is arranged on the inner side of the top of the one-step composite outer die. The inner die is cylindrical, an inner die convex ring is arranged on the outer side of the bottom of the inner die, and an inward inclined inner die clamp ring is arranged on the inner side of the top of the inner die. The outer diameter of the inner die convex ring of the inner die is larger than the inner diameter of the one-step composite outer die and smaller than the outer diameter of the convex ring. The one-step composite die has the advantages of rapid forming property and more precise size controllability.
Description
technical field [0001] The invention belongs to the technical field of moulds, in particular to a composite mould. Background technique [0002] At present, the production of battery steel shells uses progressive continuous ordinary molds, which are straight up and down, and the mold is punched in a single way. Only ordinary straight-walled steel shells can be produced. The steel shells produced have large limitations and thick walls, resulting in small capacity of the steel shells. It cannot meet the basic requirements of the existing high-capacity lithium battery steel case. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art, and provides a one-time composite mold, which has the advantages of fast forming, more precise dimensional control and the ability to punch new steel shells with different wall thicknesses at one time. [0004] In order to solve the above technical problems, the present invention provides the foll...
