Valve casting production line

Abstract

The invention relates to the technical field of valve casting, in particular to a valve casting production line. The valve casting production line comprises a shakeout machine. The shakeout machine comprises a supporting assembly, an excitation assembly, a shakeout bin and a pre-regeneration body bin. A sieve plate is arranged in the shakeout bin. A sieve frame is fixedly connected with the peripheral edge of the sieve plate. Crushing parts are arranged in both the sieve frame and the shakeout bin. Each crushing part is formed by a crushing baffle and a crushing cone in an integrated manner. The excitation assembly comprises an excitation plate, a first vibration motor and a second vibration motor, wherein the first vibration motor and the second vibration motor are arranged on the excitation plate. The first vibration motor and the second vibration motor are the same in model selection, and rotate reversely and synchronously. The valve casting production line has the beneficial effects that because of the first vibration motor and the second vibration motor which rotate reversely and synchronously, the shakeout bin only vibrates in the vertical direction, and the crushing efficiency of the crushing cone is improved; because the shakeout bin has the secondary crushing capacity, separation between a casting and molding sand is high in efficiency; and the structure is simple, andthe noise is low.

Description

technical field [0001] The invention relates to the technical field of valve casting, in particular to a valve casting assembly line. Background technique [0002] The sand casting process is a casting method in which sand is used as the main molding material to prepare molds. Sand casting is the most traditional casting method. Due to the characteristics of sand casting (not limited by the shape, size, complexity and alloy type of parts, short production cycle and low cost), sand casting is still the most widely used casting method in casting production, especially for valves, etc. Single piece or small batch castings. [0003] Shaking sand is an essential link in the production process of castings. The function of the ordinary inertia vibration shakeout machine is to transport the cooled sand block and sand box with castings to the shakeout machine, and the shakeout machine vibrates under the drive of the vibration motor to separate the sand block from the casting.

Problems solved by technology

However, the sand shakeout machines in the prior art have horizontal and vertical vibrations, which not only cause high noise, but also have low separation efficiency for sand blocks and castings.
