Quantitative feeding device for casting spheroidal graphite cast iron

Abstract

The invention relates to a quantitative feeding device for casting. The quantitative feeding device comprises a material storage bin, a supporting frame and a cantilever; the quantitative feeding device is characterized in that the material storage bin is fixed to the cantilever, the cantilever is arranged on the supporting frame, a balancing weight is arranged on the other side of the supporting frame, an infrared sensor is arranged on the supporting frame, and the discharging direction of the material storage bin and the detecting direction of the infrared sensor are located in one plane; and a lifting type plug stick is arranged in the material storage bin and connected with a lifting type plug stick driving mechanism located on the cantilever. The quantitative feeding device has the beneficial effects that when molten iron flows through a detecting position of the infrared sensor, a PLC drives the lifting type plug stick to upwards move, the material storage bin is opened, automatic feeding is achieved, and conversely, feeding is stopped; through the feeding process synchronous to metal liquid, the material adding time and the stability of adding amount of materials are guaranteed, operation of quantitative feeding in the pouring process is achieved, instability of manual operation and other interference factors are avoided, the operation stability is improved, operation risks are reduced, and the controllable operation process is achieved.

Description

technical field [0001] The invention relates to a quantitative feeding device for casting ductile iron. Background technique [0002] The existing feeding device includes a hand-held storage bin and a hand-held baffle. The hand-held baffle is located below the outlet of the hand-held storage bin and is used to block the outlet. During the casting process, the molten iron flows out of the pouring ladle. Adding auxiliary materials in molten iron, by manually controlling the switch of the outlet of the storage bin, the synchronization and operation safety of the addition are very poor; the effect of adding auxiliary materials due to operation errors is very unstable, and thus leads to batches of waste products. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a quantitative feeding device for casting ductile iron with high stability, safe operation and good synchronization. [0004] The technical scheme...
