It is caused by the weak strength and stiffness of the hydraulic cylinder of the scrap iron briquetting machine. According to the uniform load theory of material mechanics, the strength and stiffness are distributed in a parabola, which is proportional to the uniformly distributed pressure of the working oil pressure and the fourth power of the uniform load length. Therefore, the expansion of the pipe wall is easy to occur in the slender cylinder, and the expansion position is often close to the midpoint of the high-pressure cavity. Then, in view of the reason why the hydraulic cylinder block of the briquetting machine is easy to swell, this problem will be discussed in detail. The reasons are mainly reflected in the following four aspects:
1. It is the hydraulic cylinder of scrap iron forming machine that may be due to material or process problems during production, resulting in insufficient strength and stiffness.
2. The materials used in the hydraulic cylinder of the scrap iron briquetting machine also have unreasonable reasons in the structural design. Perhaps there is a special high pressure phenomenon in the operation of the briquetting machine. For example, for a piston with large load or high speed, a large inertia force will occur during the working process of the hydraulic cylinder. When it stops instantaneously, the internal pressure value suddenly increases greatly, which leads to the expansion of cylinder diameter, etc.
3. The hydraulic cylinder of scrap forming machine is often overloaded. Restart after emergency stop will make the instantaneous oil pressure exceed 2 times, and it is easy to cause expansion in the cylinder.
4. The material of hydraulic cylinder of scrap iron briquetting machine may be unreasonable in manufacturing structure design. If the low strength steel cylinder is abused, the stability coefficient will be reduced. If the hydraulic cylinder is used for a long time, the diameter of the hydraulic cylinder will inevitably swell and deform.
Then, the causes of the hydraulic cylinder wall swelling of the scrap iron briquetting machine have been found. What measures should be taken?
1. Operate the scrap iron briquetting machine according to the operation and operation requirements, and do a good job in daily protection and maintenance.
2. When purchasing scrap iron briquetting machine equipment, observe whether the hydraulic cylinder wall is provided with a reinforcement structure.
3. After the equipment operates for a period of time, if the deformed inner diameter of the hydraulic cylinder of the scrap metal briquetting machine is relatively severe, reinforcement measures should be taken. For the wall, honing method should be used to repair it.
The above is about the reason analysis of the hydraulic cylinder wall swelling and deformation in the scrap iron briquetting machine and the remedial measures that should be taken. It is expected that through the analysis of this article, you can help you deal with this problem and make the scrap iron briquetting machine play its role and value smoothly in the production and operation.
