Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of casting technology, and specifically relates to a stamping device for integrally forming a thin metal sheet for plugging a straight sprue in a pouring cup. BACKGROUND

[0002] In casting pouring, in order to prevent a small amount of molten iron from entering a mold cavity in the initial stage of pouring and forming casting defects such as iron beans and dirty holes, a "water gap plug" is usually arranged at a straight sprue of a pouring cup. When the molten iron surface reaches a certain height, the "water gap plug" is lifted. This method has some problems in actual production. First, the "water gap plug" is mostly made of graphite material, and repeated use can cause damage to the graphite column, resulting in liquid leakage and failing to play a good plugging role. Second, when the liquid surface in the pouring cup rises to a certain height and the "water gap plug" needs to be lifted, manual picking or mechanical transmission is usually adopted. In manual picking, the "water gap plug" cannot be smoothly lifted due to the pressure of the molten iron occasionally, affecting pouring. In mechanical transmission, the "water gap plug" cannot be lifted due to mechanical failure. Third, due to the characteristics of the graphite material, the "water gap plug" can also be broken in the straight sprue, resulting in failure to pour. In addition, no matter what way the "water gap plug" is lifted, workers need to operate close to the "water gap plug", which has certain safety risks. Therefore, it is necessary to improve the "water gap plug". A thin metal sheet can be used in combination with a custom-made straight sprue pipe, and the thin metal sheet is embedded in the straight sprue before pouring. During pouring, the thin metal sheet is melted by the rising temperature of the molten iron in the pouring cup, avoiding human intervention in the process, reducing errors, and avoiding safety risks. Therefore, a large number of thin metal sheets for plugging the straight sprue in the pouring cup are needed in this production process, and the stamping manufacturing device of the thin metal sheet is provided.
