Automatic production system for metal gravity casting

Abstract

The invention discloses an automatic production system for metal gravity casting. The system comprises a heat-preserving furnace, a sliding table, a plurality of gravity casting machines, a robot, a liquid taking arm and a control system, wherein the heat-preserving furnace is used for containing molten metal and keeping the temperature of the molten metal within a certain range; the sliding table is arranged beside the heat-preserving furnace and used for bearing the robot; the gravity casting machines are arranged on the two sides of the sliding table; the robot is arranged on the sliding table and can make reciprocating movement on the sliding table; the liquid taking arm is connected with the robot and provided with a liquid taking spoon and a servo driving system for driving the liquid taking spoon to rotate; the control system is used for controlling the liquid taking arm to take liquid from the heat-preserving furnace when the robot slides to the heat-preserving furnace and controlling the robot to move to the position beside the pre-determined gravity casting machine after the liquid is taken, then, the liquid taking arm is controlled to pour the molten metal to the pre-determined gravity casting machine, and next, the robot is controlled to slide to the initial position after the molten metal is poured by the liquid taking arm. According to the production system, the production efficiency, the safety and the percent of pass of products can be improved.

Description

Technical field [0001] The invention relates to the technical field of auxiliary equipment for metal gravity casting, in particular to an automated production system for metal gravity casting. Background technique [0002] At present, in the production of metal products, casting machines are often used for production. The prior art generally uses manual methods. Workers scoop molten metal (also called metal soup) from the holding furnace, then pour them into the casting machine, and then turn them over. Forming; Since the temperature of the molten metal reaches a high temperature of about 700°C, this method of manual liquid extraction has the following disadvantages: [0003] 1. Low qualification rate: Because manual operation is often limited to visually scooping soup, it is easy to cause the amount of soup scooped to be unstable, resulting in a low qualified rate of produced products. [0004] 2. Poor safety: manual operation makes workers work in a high temperature environment fo...

AI Technical Summary

Problems solved by technology

[0003] 1. Low qualified rate: Since manual operation is often limited to visual scooping of soup, it is easy to cause instability in the amount of scooped soup, resulting in low qualified rate of produced products

[0004] 2. Poor safety: Manual operation makes workers work in high temperature environment for a long time, which is prone to work fatigue and burnout

In addition, workers are exposed to danger for a long time, and the air is full of exhaust gas, which prevents them from working for a long time

[0005] 3. Low production efficiency: In the manual operation mode, workers are always in a high-temperature environment, and they must rest for 15 minutes every hour of work, otherwise the human body cannot withstand the long-term heat, resulting in production suspension and low production efficiency

[0006] 4. Large energy loss: In the current manual operation mode, workers must rest for 15 minutes every hour, and all production equipment cannot be stopped at the same time. Once stopped, the temperature is not enough to prevent pouring and molding, which will cause huge energy consumption such as electricity.

[0007] 5. The probability of misoperation is high: workers are prone to fatigue and burnout in high-temperature environments, so during the operation of equipment, it is inevitable that misoperation of equipment will occur, resulting in poor product quality and increased loss
