Sealing head forming mold with replaceable draw beads

Abstract

The invention discloses a sealing head forming mold with replaceable draw beads. The sealing head forming mold is matched with a double-action press and is characterized by comprising a pressing plate, n draw bead baffles, n detachable draw beads, a concave mold and a convex mold. Different draw bead baffles and detachable draw beads are replaced to form a mold for punching different draw beads. Through combination of different detachable draw beads and draw bead baffles, the replacement of the draw beads is achieved, so that different draw bead resistances are supplied for punching and forming sealing heads with different material thicknesses, and the purpose of punching the sealing heads with different material thicknesses by using the same mold can be achieved.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a head forming die with replaceable drawbeads, mainly for the head forming dies with replaceable drawbeads. Background technique [0002] As a pressure-bearing part, the head has different thickness requirements for heads with the same shape according to the specific pressure-bearing requirements. The early stamping forming was realized by the step-by-step forming of multiple molds. Although the step-by-step forming can realize the stamping and forming of the head, it has the disadvantages of cumbersome procedures, high production costs, and is not conducive to mass production; with the development of stamping technology, in The introduction of drawbeads in the head forming has realized the one-step cold stamping of the head, which is improved compared with the step-by-step forming, but there is still a single mold that can only produce one type of head, which has high prod...

Problems solved by technology

The early stamping forming was realized by the step-by-step forming of multiple molds. Although the step-by-step forming can realize the stamping and forming of the head, it has the disadvantages of cumbersome procedures, high production costs, and is not conducive to mass production; with the development of stamping technology, in The introduction of drawbeads in the head forming has realized the one-step cold stamping of the head, which is improved compared with the step-by-step forming, but there is still a single mold that can only produce one type of head, which has high production costs, low production efficiency, and scrap rate. high disadvantage

In the current head forming mold, the ribs of the drawbead are usually fixed on the binder plate or the die, but this kind of drawbead fixed mold cannot provide different drawbead resistance, and the mold can only be used for plates of the same thickness. Processing and forming

Using the same mold to process heads with different material thicknesses requires different drawbead resistances, while drawbead fixed molds cannot provide different drawbead resistances

In addition, this type of fixed drawbead mold is inconvenient to repair the mold, which may cause the die to be scrapped because the drawbead cannot be repaired, thus increasing the repair time of the mold and reducing the service life and production efficiency of the mold. thereby increasing production costs
