The problem of adhesion occurs frequently in the automated production line for forging.

The automated forging production line, apart from the problem of low forging efficiency, also exhibits a significant issue of product sticking to the mold in the context of the automated forging project. Such problems can cause the production line to come to a halt and affect the production schedule. The main reason for the occurrence of these problems is that the forging process needs to be carried out in a high-temperature environment, and after the product melts, it is prone to stick to the mold. Regarding this issue, there are mainly four approaches to address it:
1. It is done by manually cleaning the mucosal area.
2. It involves applying release agent to the molds to enhance their lubricity, thereby reducing the likelihood of the molds adhering to the product materials.
3. The hydraulic machine equipment is installed at the upper part of the mold. Through hydraulic pressure, the forged products are lifted off the mold in real time, which effectively prevents the occurrence of adhesion problems.
4. The improvement of the mold's anti-sticking performance is achieved by modifying the mold design, thereby preventing the occurrence of sticking problems.
In the automated forging production line, if the manual method of knocking and cleaning the adhered substances requires a certain amount of manpower and cost, the optimized method of applying release agent to the molds is more convenient to operate. However, in this automated forging production line project, this method also has certain drawbacks. Under the previous manual operation mode, people's application of release agent was not a mechanized task. It could be reasonably controlled based on people's perception, touch, etc., such as the amount used. But in the automated production mode, the application of release agent is directly completed by the forging robot. The forging robot merely focuses on executing a program instruction. As for whether this instruction is correct or not, and whether the execution is complete, the forging robot does not make subjective judgments. However, according to the changes in the actual production situation in the workshop, the spraying amount of the release agent will not remain constant.
In this regard, based on the previous idea of using a hydraulic press to push out the mucosal products, the key point lies in how to precisely control the operation timing of the automated hydraulic press, so that it can push out the products at the exact moment of the product forging. To achieve this goal, a comprehensive consideration of factors such as the press stroke, the time of descent, the impact pressure, and the rebound speed is required, and it is necessary to ensure that these factors can be controlled under varying conditions, which is quite challenging. Based on this, in the design process of the automated forging production project, the original thinking was changed. Considering that the electrical control effect cannot be achieved, mechanical direct control can be used instead. Compared with electrical control, the time nodes of mechanical control are clear, which can effectively ensure the tightness of the operation nodes.
The original control mechanism of the automated hydraulic press equipment was removed, and then a mechanical control mechanism was reinstalled. Through the hard spring mechanism, the product would be pushed out at the moment of each strike. As a result, the contact time between the product and the mold would be significantly shortened, and the problem of adhesion would be effectively improved.
