As a fundamental and practical hydraulic machinery, the simple four-column hydraulic press has been widely applied in numerous fields due to its unique advantages. With the continuous development of the manufacturing industry, higher requirements have been put forward for the flexibility, economy, and efficiency of production equipment. Thanks to its simple structure, convenient operation, and wide applicability, the simple four-column hydraulic press has become an ideal choice for small and medium-sized enterprises as well as small processing workshops to achieve product molding and processing. In-depth research on its applications and characteristics helps to give full play to the performance of this equipment and promote the development of related industries. In the metal processing industry, the simple four-column hydraulic press is one of the key equipment for metal forming. During the manufacturing process of automotive parts, the preliminary forming of engine blocks requires precise pressure control. The simple four-column hydraulic press can stamp metal sheets into the required shapes through stable pressure output. For automotive body panels, such as car doors and hoods, their complex curved surfaces can also be processed with the help of this equipment in conjunction with specific molds. In addition, in the hardware products industry, the simple four-column hydraulic press can efficiently complete forming processes such as stretching and bending, from daily metal tableware to decorative metal products, meeting diverse market demands. The production of plastic products is inseparable from molding equipment, and the simple four-column hydraulic press also performs outstandingly in this field. Take daily necessities such as plastic basins and buckets as examples. After putting plastic raw material particles into the mold cavity, the simple four-column hydraulic press applies pressure to make the plastic melt and fill the cavity under heat. After cooling, the molded products can be obtained. For the production of plastic toys, due to the variety of toy shapes, the simple four-column hydraulic press can quickly produce different styles of toys by changing molds, with high production efficiency and stable product quality. Powder metallurgy is a process of preparing parts by pressing metal powders or other powder materials into shape. The simple four-column hydraulic press is mainly used in the powder pressing stage in this field. When producing mechanical parts, uniformly mixed metal powders are put into the mold, and the hydraulic press applies high pressure to make the powder particles combine closely, forming blanks with certain shapes and strengths. By controlling the pressure and pressing time, the density and dimensional accuracy of the blanks can be precisely adjusted, laying a foundation for subsequent processes such as sintering. The vulcanization molding process of rubber products requires certain pressure and temperature conditions, and the simple four-column hydraulic press provides the necessary pressure guarantee. In tire production, after putting the mixed rubber semi-finished products into the tire mold, the hydraulic press quickly applies pressure and maintains it for a certain period, so that the rubber undergoes a vulcanization reaction in the mold, forming tires with high strength and good elasticity. Similarly, for rubber seals, rubber pads and other products, the simple four-column hydraulic press can also ensure that they obtain accurate shapes and sizes during the molding process, meeting the sealing and shock absorption requirements of different industrial equipment. The simple four-column hydraulic press adopts the classic four-column structure, mainly composed of the upper crossbeam, lower crossbeam, four columns, and the movable crossbeam. This structural design has good symmetry and stability, and can evenly bear the pressure during the working process. The upper and lower crossbeams are fastened to the columns by nuts or other connection methods to form a rigid frame. The movable crossbeam can slide up and down on the columns, driving the mold to perform pressing actions. Compared with the structures of complex hydraulic equipment, the simple four-column hydraulic press has fewer components and relatively simple manufacturing processes, which not only reduces the manufacturing cost of the equipment but also facilitates installation and maintenance. The equipment is usually equipped with an intuitive operation panel, and operators can master the operation method proficiently after simple training. Through the buttons or handles on the operation panel, the start, stop, lifting of the slider, and pressure adjustment of the hydraulic press can be easily controlled. In addition, some simple four-column hydraulic presses also have semi-automatic or automatic operation modes, which can automatically complete a series of actions such as pressing, pressure maintaining, and return stroke according to the preset program, greatly improving production efficiency and reducing the labor intensity of operators. The hydraulic system is the core part of the simple four-column hydraulic press for pressure output, mainly including components such as oil pumps, cylinders, and hydraulic valves. The oil pump converts the mechanical energy of the motor into the pressure energy of the hydraulic oil and transports it to the cylinder through the oil pipe. In terms of pressure control, the hydraulic system is equipped with pressure control components such as relief valves and reducing valves, which can precisely adjust the system pressure according to different process requirements. Whether it is metal forming processing that requires a large amount of pressure or plastic product pressing with relatively low pressure requirements, the simple four-column hydraulic press can provide stable pressure output to ensure the consistency of product molding quality. One of the significant characteristics of the simple four-column hydraulic press is its high adaptability to different production needs. By changing molds of different specifications and shapes, the equipment can quickly switch to produce different types of products, and it is competent for both simple flat plate pressing and complex curved surface forming. At the same time, parameters such as its pressing speed and stroke can also be adjusted according to actual production needs to meet diversified process requirements. This flexibility gives the simple four-column hydraulic press unique advantages in the production mode of small batches and multiple varieties. Compared with large and complex hydraulic equipment, the simple four-column hydraulic press has a lower manufacturing cost. Due to its simple structure, it requires fewer components and relatively less complex processing techniques, reducing raw material and manufacturing costs. During operation, the simple four-column hydraulic press has a small power demand and low energy consumption, further reducing production costs. In addition, its maintenance is relatively easy, and the cost of replacing components is not high, keeping the overall use cost of the equipment at a low level. It has a high cost-performance ratio for small and medium-sized enterprises with limited capital and technical strength. With its extensive applications in metal forming, plastic products processing, powder metallurgy, rubber products production and other fields, as well as remarkable characteristics such as simple structure, convenient operation, stable pressure, strong adaptability, and high cost-effectiveness, the simple four-column hydraulic press has become an indispensable and important equipment in modern industrial production. With the continuous advancement of industrial technology and the continuous growth of manufacturing demands, the simple four-column hydraulic press will continue to develop and improve in terms of optimizing structural design, enhancing automation, and improving pressure control accuracy, further expanding its application areas and providing more powerful support for the efficient and stable operation of industrial production. In the future, the research and application of simple four-column hydraulic presses will develop in-depth towards intelligence, energy conservation, and environmental protection to better meet the development needs of the manufacturing industry in the new era 五、技术参数（Technical Parameters）：
