Description
Technical Field
The invention relates to the technical field of sand casting, in particular to an automatic sand filling method of a continuous sand mixer.
Background
Sand casting is widely used for preparing castings made of aluminum alloy, cast steel, magnesium alloy and the like, and various castings with complex shapes, and is an extremely important casting method. Because the sand mold is used as the forming mold, the mold has good air permeability, the defects of air holes, cold shut and the like are not easy to appear in the casting process, and the casting formed by the sand mold casting method has excellent mechanical properties. In the sand casting process, the preparation of the sand mold is very important. The good sand mould not only needs to have a forming shape, but also needs to have certain size precision and roughness so as to ensure the size and the surface quality of a formed part, and meanwhile, the sand mould also needs to have proper compactness so as to avoid the occurrence of box crossing, poor air permeability and the like. However, the traditional sand mold manufacturing process mainly depends on manual sand filling and molding, so that the quality consistency of the sand mold is poor, the molding efficiency is low, and human resources are wasted. Therefore, how to improve the quality of the sand mold and the molding efficiency is of great importance.
Disclosure of Invention
The invention aims to provide an automatic sand filling method of a continuous sand mixer, which can improve the sand mold quality and the molding efficiency.
In order to achieve the aim, the automatic sand filling method of the continuous sand mixer comprises the following steps:

The whole process is highly automatic, artificial participation is not needed, the sand mold processing efficiency is high, the quality of the sand mold repeatedly manufactured has high consistency, and uncertain factors of artificial processing and manufacturing are eliminated.
Further, the step S2 specifically includes the following steps:
s21, scanning the casting model through the camera, and generating warning information if the coded information is not identified on the casting model, and informing an expert end of manual sand filling; if the coded information is recognized on the casting model, executing step S22;
and S22, after the coded information is recognized, obtaining the modeling parameter information of the corresponding casting model and the motion trail information of the sand mixing robot from the database, and if the modeling parameter information and the motion trail information of the sand mixing robot are not obtained, generating warning information and informing an expert end of manual sand filling.
When the coded information is not recognized on the casting model or the modeling parameter information of the corresponding casting model and the motion trail information of the sand mixing robot cannot be acquired from the database, warning information can be generated and an expert end is informed to perform manual sand filling. The manual sand filling is carried out by informing the expert end, so that the condition that the sand mixing robot stops working midway and is lack of intervention to influence the whole working efficiency can be avoided, and on the other hand, technical experts are informed to record related sand filling modeling data to avoid the same problem in the follow-up process.
Further, the generation of the coded information on the casting model in the step S2 specifically includes the following steps:
s23, marking coded information on the casting model, associating the casting model with the coded information, and storing the casting model and the coded information in a database;

and S25, storing the modeling parameter information of the casting model and the movement track information of the sand mixing robot when the sand mixing robot is controlled into a database, and associating the modeling parameter information of the casting model and the movement track information with the coding information of the casting model.
When the sand mixer is manually operated to move for filling sand, the molding parameter information and the movement track information of the sand filling completed for the first time are recorded and stored in the database. When the same coding information is identified again, the modeling parameter information of the corresponding casting model and the motion trail information of the sand mixing robot can be obtained from the database, and the sand mixing robot is controlled to automatically complete sand filling, so that the working efficiency is improved.
Further, the molding parameter information comprises a sand filling starting point, liquid material proportioning, sand output, large arm rotation speed, small arm rotation speed, a large arm rotation angle and a small arm rotation angle; the large arm rotation speed is (300-1000) mm/min, the small arm rotation speed is (500-1500) mm/min, the large arm rotation angle is 0-120 degrees, the small arm rotation angle is 0-260 degrees, the liquid material comprises resin and a curing agent, wherein the mass ratio of the resin to the molding sand is (0.8-1.2)%: 1, the mass ratio of the curing agent to the resin is 0.5: 1.
The setting of molding parameter information, through quantifying each step for sand mould manufacturing efficiency is higher, the specification is more unified, sand mould quality uniformity is high, the foundry goods quality of production is more stable.
Further, the method also comprises the following steps:
s26, analyzing the segment-type action track in the motion track information, and carrying out continuous action optimization on the segment-type action track;
and S27, analyzing the segmented sand output in the molding parameter information, continuously optimizing the segmented sand output, recording the actual sand output and collecting the residual sand output, calculating the actual sand consumption according to the actual sand output and the residual sand output, storing the actual sand consumption into a database, and correlating the actual sand consumption with the coding information of the casting model.
The continuous action optimization and the continuous sand discharging optimization are used for ensuring the continuity of the operation of the sand mixing robot, so that the time is saved, and the working efficiency is improved. The calculation of the real sand consumption can ensure that the sand consumption is enough to be used without generating the problem of excessive waste, thereby saving the material cost.
