Benefits of technology

This technology makes it easier than ever before to make complicated or shaped items that are difficult to form by hand without requiring expensive tools like diesel guns. It also helps save on materials used during production while still producing quality products at competitive prices.

Problems solved by technology

The technical problem addressed by this patented method relates to improving the accuracy and productivity of creating complicated parts through multi directionally die forged materials used during hydrostatic pressure casting (HIP). Existing methods are limited because they require expensive equipment or slow down production times due to issues such as complexity shape design requirements.

Abstract

The invention discloses a left and right convex-mold die-forging process, which comprises an upper concave mold, a lower concave mold, and a multidirectional die-forging oil press, further comprises a left convex mold and a right convex mold. The process comprises the following steps of step A preheating the upper concave mold, the lower concave mold, the left convex mold and the right convex mold by using a heater; step B placing a forged-piece material in the lower concave mold, and introducing a low pressure into the multidirectional die-forging oil press to enable the upper and lower surfaces of the forged-piece material to be positioned and molded; step C continuously introducing a high pressure into the multidirectional die-forging oil press to enable the upper concave mold to be pressurized and kept to be pressed with the lower concave mold; step D then introducing a medium pressure into the multidirectional die-forging oil press to enable a convex-mold body to be pressed into the forged-piece material to finish the die pressing, positioning and molding of the left and right lateral surfaces of a forged piece; step E sequentially removing the medium pressure and the low pressure of the multidirectional die-forging oil press, and taking out the forged piece to obtain a finished-product forged piece. The left and right convex-mold die-forging process has the advantages of simplicity and rapidness in operation, good applicability and strong practicability, and the molding of the forged piece in a complicated structural shape can be effectively finished, so that the utilization ratio of the material is markedly increased, and the forging cost is lowered.
