Embodiment 1

[0038] The embodiment of the present invention provides an automatic quantitative weighing device for molten metal, such as figure 1 , figure 2 with Figure 6As shown, it includes a bracket 1, a balance board 2 that is movably arranged on the bracket 1 through a rotating shaft, a pouring bucket 3 that is movably arranged at one end of the balance board 2, a weight storage box 5 that is arranged at the other end of the balance board 2, and the The driving mechanism of the pouring barrel connected to the barrel 3; the pouring barrel 3 is used to receive the molten metal in the external ladle or crucible, and is eccentrically arranged on the balance plate 2 through the rotating shaft, and its center of gravity is located outside the balance plate 2. The pouring barrel drive mechanism includes a positioning assembly for limiting the turning of the pouring barrel 3 and a trigger assembly for releasing the limiting assembly.

[0039] It also includes a metal ball circulation mech...

Embodiment 2

[0060] An embodiment of the present invention provides an automatic quantitative weighing method for molten metal, the method comprising:

[0061] Step S1: Obtain the weight of the prefabricated casting, place an equal amount of counterweights in the counterweight holding box 6 of the balance board according to the weight of the prefabricated casting, the balance board 2 tilts, and the pouring bucket 3 is hinged on the balance board 2 and keep level;

[0062] Step S2: Pouring the molten metal into the positioned pouring barrel 3, when the weight of the molten metal gradually increases until the balance plate 2 tilts in the opposite direction, the pouring barrel 3 eccentrically arranged on the edge of the balance plate 2 will be released And it rotates under the action of its own gravity, and the molten metal liquid in the pouring barrel 3 is poured into the mould; at the same time, the metal ball returns to the initial end of the metal ball release groove under the action of t...

Abstract

The invention provides an automatic quantitative weighing device and quantitative weighing method for molten metal. The automatic quantitative weighing device for molten metal comprises a support, a balance plate, a pouring bucket, a weight storage box and a pouring bucket driving mechanism, wherein the balance plate is movably arranged on the support through a rotating shaft, the pouring bucket is movably arranged at one end of the balance plate, the weight storage box is arranged at the other end of the balance plate, and the pouring bucket driving mechanism is connected with the pouring bucket; the pouring bucket is eccentrically arranged on the balance plate through the rotating shaft, and the center of gravity of the pouring bucket is located outside the balance plate; and the pouring bucket driving mechanism comprises a positioning assembly used for limiting turning of the pouring bucket, a triggering assembly used for releasing the limiting assembly, and a metal ball circulating mechanism used in cooperation with the triggering assembly. The automatic quantitative weighing device and quantitative weighing method for molten metal have the beneficial effects that molten metal can be quantitatively weighed accurately, the working efficiency is improved, the quality of castings is improved, and materials are saved.

Description

technical field [0001] The patent of the invention relates to the technical field of metallurgical equipment manufacturing, in particular to an automatic quantitative weighing device and a quantitative weighing method for molten metal. Background technique [0002] In the metallurgical industry, after the ore is mined, it must be smelted in a high-temperature furnace to obtain the required alloy liquid, and then pour the alloy liquid into the mold. When the amount of poured alloy liquid is low, the solution cannot be obtained in the mold cavity. Feeding can easily lead to shrinkage, porosity and shrinkage cavities, forming casting defects. When the amount of poured alloy liquid is high, it is easy to cause waste of alloy liquid. Therefore, quantitative weighing of molten metal liquid is important for improving the quality of castings, saving resources and protecting the environment. has important practical significance. In addition, many metallurgical factories and scientif...
