Problems solved by technology

[0008] The technical problem to be solved and the technical task proposed by the present invention are to overcome the inconsistency of the temperature change of the molten metal in various parts of the mold cavity easily caused by the existing pouring method, and the overflow or splash of the molten metal caused by the excessive pouring flow rate of individual parts To solve the defects of the mold, a robot quantitative pouring method is provided. For this reason, the present invention adopts the following technical solutions:

Embodiment 1

[0028] Such as Figure 1~4 As shown, it is four state schematic diagrams when the set rotation range of the ladle of the present invention is divided into three angle segments by PLC, and the turning time of each angle segment is set by PLC at the same time, so that the robot takes the ladle in each Each angle segment is flipped at a constant speed, that is, according to the following Figure 5 The broken line segment b of the corresponding relationship between the rotation angle and the time shown is poured, so that the defects of the prior art can be avoided.

Embodiment 2

[0030] Let the robot carry the ladle according to the following Figure 6 The gradual curve c of the corresponding relationship between the rotation angle and the time shown is poured, so that the defects of the prior art can be avoided. Moreover, the speed between the various angle segments is continuous, which can better avoid the splashing of molten metal caused by sudden changes in speed.

[0031] The industrial robot controls the rotation angle of the ladle, and divides the rotation angle of the ladle, such as into three angles, or it can be divided into any angle according to the needs, and each angle is input through the external PLC control program. The time variable is associated, and the value of the time variable can be manually input through the PLC operation terminal. For example, the time variable of 0-15 degrees is 2 seconds, which means that the machine will control the ladle from 0 degrees to 15 degrees in 2 seconds. , if the time variable is set to 5 seconds...

Abstract

The invention discloses a robot quantitative pouring method which belongs to a pouring method. The existing method easily causes the inconsistent temperature change of molten metal at each part in a mold cavity and the overhigh pouring flow rate of a certain part so that the molten metal overflows or spills out of a mould. The robot quantitative pouring method uses a robot for taking a pouring ladle to the mould and controlling the set continuous overturn angle of the pouting ladle so as to pour. The robot quantitative pouring method is characterized in that the set angle is divided into a plurality of angle sections, and the pouring ladle turns over according to a set speed in each angle section to pour. When the molten metal is poured in, with different structures of the mould, the pouring quantity and the pouring speed can be adjusted in the process of pouring so as to have obvious action of improving the making rate of castings with relatively complicated structures such as cylinder covers, aluminum wheels of the motorcycle, and the like. In addition, the same pouring ladle is used for pouring moulds in different sizes so as to change pouring tracks aiming at different moulds.

Description

technical field [0001] The invention relates to a casting method, in particular to a robot quantitative pouring method. Background technique [0002] Pouring is the process of injecting molten metal into the mold during the casting process. Most of the existing pouring methods are realized by scooping up an appropriate amount of molten metal with a ladle and pouring the molten metal into the mold. For example, No. 200420109280.1 "robot The Chinese utility model patent of "casting mechanical arm" and the Chinese utility model patent of No. 200520015393.X "a kind of automatic metal casting and casting equipment" relate to this pouring method. [0003] The above pouring method needs to pour the molten metal into the mold cavity in time and continuously, so that the gravity and fluidity of the molten metal can quickly fill the cavity of the mold before the molten metal crystallizes and solidifies, so as to avoid the poor flow of the molten metal and cause the product It cannot ...
