Pressurizing casting equipment and process for gun steel casting

Abstract

The invention discloses pressurizing casting equipment for gun steel casting. The equipment comprises a vacuum chamber and a door plate, the door plate is installed at the front side of the vacuum chamber in an opening and closing manner, and the pressurizing casting equipment further comprises a smelting mechanism installed at the left side of the upper surface of the vacuum chamber, a vacuum pump, a refrigerator, turnover mechanisms, fixed molds and first hydraulic oil cylinders. The vacuum pump is mounted in the middle of the upper surface of the vacuum chamber, and an air inlet communicates with the top of the vacuum chamber through an air pipe; the refrigerator is mounted at the right side of the upper surface of the vacuum chamber; and the two turnover mechanisms are fixedly connected to the bottoms of the left inner wall and the right inner wall of the vacuum chamber correspondingly. The fixed molds are arranged at the inner sides of the turnover mechanisms in a turnover manner; and the two first hydraulic oil cylinders are installed at the left side and the right side of the top of an inner cavity of the vacuum chamber correspondingly. Active cooling of the fixed molds and a movable mold can be achieved, the casting efficiency is improved, in addition, blank materials can be taken out without being grabbed by any equipment, the fixed molds are prevented from being damaged, and the casting safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a pressurized casting equipment and a process for gun steel casting. Background technique [0002] The most basic function of the artillery barrel is to launch the projectile to a designated location at a certain speed, so the barrel is part of the artillery-ammunition system that contains the projectile and propellant. Due to the extremely high requirements for the material of the gun barrel itself, this puts forward extraordinary requirements for the refining of steel, that is, after the steelmaking and smelting is completed, the blank needs to be forged by a hammer bed, and the residual sulfur and phosphorus in the steel are harmful. The elements that are harmful to strength and toughness are removed to meet the performance requirements, and then the impurity-removed blank is re-melted into molten steel, and the pouring is completed in a vacuum environment to pre...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a pressurized casting equipment and process for gun steel casting, to at least solve the problem that the existing technology cannot actively cool the mold after casting, the cooling time is long, which affects the casting effect of the gun barrel, and the blank is taken out Easy to damage the mold when feeding
