Abstract
The invention discloses a continuous punching mold of a vehicle engine cabin. The mold comprises a guide traction lubrication structure, a leveling limiting fixed-length punching structure, a horizontal feeding structure, a hole position primary positioning punching and secondary horizontal positioning pull structure, a continuous punching waste dropping and feeding material detecting structure and a flat cutter discharge structure. A steel strip to be machined is sprayed with lubricant by itself, and is driven by a traction sub-mold to forwards move. Then, the steel strip enters the leveling limiting fixed-length punching structure to finish the striping fixed-width punching, and enters the horizontal feeding structure to perform the hole position primary positioning punching; the secondary horizontal positioning pull structure guarantees the continuous horizontal forward movement of materials; when the steel strip enters the continuous punching waste dropping, the product is basically molded; the steel strip is fed into the material detecting structure to detect the punching aperture and the striping fixed-length size; and finally, the flat cutter discharge structure performs the fixed-length cutting discharge. The six procedures of leveling, striping, feeding, punching, detection and discharge in the engine part machining process are integrated and finished by one set of mold, so that the production flow is shortened, the production efficiency is improved, the production cost is reduced, and the mold is suitable for continuous large-batch production.
