Pouring system

Abstract

The invention discloses a pouring system, and belongs to the technical field of casting equipment. A pouring machine comprises a pouring position correction mechanism and a pouring device; the pouringposition correction mechanism comprises a pouring position correction vehicle track, a pouring position correction vehicle and a longitudinal displacement adjustment device; the pouring position correction vehicle comprises a pouring position correction vehicle frame and a pouring position correction vehicle wheel connected with the pouring position correction vehicle frame in a rolling mode; thelongitudinal displacement adjustment device comprises a sand mold positioning mark, a visual positioning camera and a position correction vehicle hydraulic oil cylinder, one end of the position correction vehicle hydraulic oil cylinder is hinged to the pouring position correction vehicle frame, the other end of the position correction vehicle hydraulic oil cylinder is hinged to an oil cylinder connecting seat fixed to the ground or the pouring position correction vehicle track, and two switch control signal output terminals of the visual positioning camera control the extension or contractionof a piston rod of the position correction vehicle hydraulic oil cylinder respectively. The pouring system has the characteristics of high degree of automation, safety and reliability, stable pouringand good consistency of casting quality.

Description

technical field [0001] The invention relates to the technical field of casting equipment. Background technique [0002] Casting is the process of obtaining metal molding objects through a certain method. The pouring machine is used to pour molten iron into the sand mold. After the molten iron is cooled in the sand mold, the casting blank is obtained. During the casting operation of the production line, the sand mold molded by the sand molding machine is made of The sand mold production outlets are ejected one by one and pushed towards the direction of the pouring machine through the sand mold sliding channel. The pouring machine is installed close to the sand mold sliding channel, so that when pouring, the ladle mouth of the ladle is aligned with the position of the sand mold sliding channel.

[0002] Casting is the process of obtaining metal molding objects through a certain method. The pouring machine is used to pour molten iron into the sand mold. After the molten iron is cooled in the sand mold, the casting blank is obtained. During the casting operation of the production line, the sand mold molded by the sand molding machine is made of The sand mold production outlets are ejected one by one and pushed towards the direction of the pouring machine through the sand mold sliding channel. The pouring machine is installed close to the sand mold sliding channel, so that when pouring, the ladle mouth of the ladle is aligned with the position of the sand mold sliding channel. The pouring operation is carried out in the sand casting cup of the corresponding sand mold; in actual work, the sand mold will be longitudinally offset within a certain range relative to the installation position of the pouring machine, which will cause the pouring mouth of the ladle relative to the sand casting of the sand mold. The deviation of the relative position of the cup is caused by the following reasons: due to the error of the ejection distance of the sand mold molded by the sand molding machine, it will cause a longitudinal offset of the sand mold relative to the installation position of the pouring machine; in addition, due to the composition ratio of the sand mold, The amount of water added, the compaction strength and other reasons cause the thickness of the sand mold to be inconsistent, which will also cause the sand mold to have a longitudinal offset relative to the installation position of the pouring machine, so that the pouring mouth of the ladle deviates from the position of the sand mold pouring cup of the sand mold. As a result, molten iron leaks out, which affects production safety and product quality. The casting process currently used is casting by manual pouring.

The efficiency of manual pouring is low, the waste is serious, and the yield is poor. The pouring is unstable due to manual differences, and there are phenomena such as broken pouring, undercasting, and overcasting. The quality of castings is unstable, and manual pouring is not suitable for vertical line production with increasing automation. High labor cost and high risk factor
