During the operation of the oil press, the stability of the oil press base shell is crucial. First of all, from the overall shape, the design concept of low center of gravity should be adopted. For example, the cross-sectional shape is designed to be trapezoidal or rectangular, with a wide bottom and narrow top, which can lower the center of gravity of the entire oil press, making it more stable during operation and not easy to tip over due to vibration or external impact.
In terms of material selection, both strength and weight should be taken into account. High-strength cast iron or aluminum alloy is a good choice. They can provide sufficient support to withstand the various forces generated when the oil press is working, and will not make the base too heavy. For some key force-bearing parts, such as the support feet in contact with the ground and the parts connected to the main body of the oil press, the thickness of the material can be appropriately increased or a reinforcing rib structure can be adopted.
The layout of the reinforcing ribs is also very critical. Reasonable distribution of reinforcing ribs can effectively enhance the rigidity of the shell. On the sides and bottom of the oil press base shell, criss-cross reinforcing ribs are designed according to the principles of mechanics to form a stable grid structure. These ribs can evenly distribute the local forces to the entire shell, prevent deformation or damage caused by stress concentration, and thus improve overall stability.
In the design of the connection parts, a tight and firm connection method is adopted. For example, high-strength bolts are used, and the number and diameter of bolts are increased to ensure that the connection between the oil press base shell and the oil press body and the ground support parts is tight. At the same time, reasonable stoppers and positioning structures are designed at the connection to prevent displacement or loosening due to vibration during long-term use.
Considering the vibration that may be generated when the oil press is working, a shock-absorbing structure can also be designed inside the oil press base shell. For example, installing a rubber shock-absorbing pad at the part where the base contacts the ground can effectively absorb and buffer the vibration generated when the oil press is running, reduce the unstable factors caused by vibration transmission, and also reduce noise and improve the comfort of the working environment.
In addition, finite element analysis simulation of the oil press base shell is also an important means of optimizing the design. By simulating the stress conditions of the oil press base shell under different working conditions, potential weak links can be accurately discovered, and then targeted structural improvements and optimizations can be made to ensure stable and reliable operation in actual use, improve the working efficiency and service life of the oil press, and reduce maintenance costs and safety hazards caused by stability issues.
