The utility model relates to a kind of non-excavation light curing repair hose manufacturing technical field, specifically to a kind of light curing hose forming machine. Including the conveying assembly for pushing multiple layers of flat cloth, the cloth folding assembly for the layering folding of multiple layers of flat cloth, cloth folding assembly is located above conveying assembly, cloth folding assembly is fixedly connected with conveying assembly. The utility model is sequentially arranged in conveying direction by multiple cloth folding units (each unit corresponds a layer of cloth), realizes the continuous, sequential folding (from top to bottom) of multiple layers of flat cloth, avoids the low-efficiency problem of traditional manual or single-layer processing, significantly improves production efficiency, and can handle multiple-layered structure simultaneously, facilitating subsequent sewing into hose. Conveying assembly promotes cloth movement, and cloth folding assembly automatically completes folding, without interrupting the process, reducing manual intervention.

This invention discloses a powder metallurgy external helical gear workpiece forming die, comprising a forming base with a forming cavity; a first punch; a second punch with a first forming end and a first connecting end, and a first through-channel within the second punch; a third punch with a second forming end and a second connecting end, and a second through-channel within the third punch; forming helical teeth on the inner surface of the second forming end; at least two clearance through holes on the second connecting end, extending circumferentially along the second connecting end; a fourth punch with a third forming end and a third connecting end; guiding helical teeth on the outer surface of the third forming end, the guiding helical teeth engaging with the forming helical teeth; and a mandrel assembly including a mounting base and at least two mandrels spaced apart axially from the mounting base. This invention can form helical teeth and holes on the helical teeth in a single die-casting operation.

The invention relates to the technical field of water electrolysis equipment, and discloses a polymer proton exchange membrane electrolysis device and an electrolytic bath with the same. The polymer proton exchange membrane electrolysis device comprises: a pair of conductive polar plates, at least one surface of which is a plane; the number of the flat plate diffusion layers is one pair, the pair of flat plate diffusion layers is arranged between the pair of conductive polar plates, overflowing runners are arranged between the flat plate diffusion layers and the conductive polar plates, and the overflowing runners between the adjacent flat plate diffusion layers and the conductive polar plates are formed on the faces, facing the conductive polar plates, of the flat plate diffusion layers or the faces, facing the flat plate diffusion layers, of the conductive polar plates; and the membrane electrode is arranged between the pair of flat diffusion layers. One surface or two surfaces of the conductive polar plate are planes, so that the forming step of the conductive polar plate is simplified, and the manufacturing cost of the conductive polar plate can be reduced. And at least one surface of the conductive polar plate is a plane without an overflowing runner, so that the planeness of the conductive polar plate can be improved.
