The equipment restricts some waste materials to the shape of a cuboid or a cube to facilitate better transportation. As a relatively high-tech product in today’s society, many of our customers think it is simple and easy to understand by looking at the appearance of the product. In fact, its built-in structure is very complicated. If customers want to make it work better for us, they must understand its built-in. There are many ways to classify the briquetting machine. According to the direction of the effect force, the briquetting machine has two types: vertical and horizontal. The briquetting machine is mostly horizontal. According to the structure type, the hydraulic press has two-column, four-column, eight-column, welded structure and multi-layer steel belt surrounding structure, etc., and medium and small vertical hydraulic presses also use C-frame type. The C-frame hydraulic press is open on three sides, which is convenient for operation, but has poor rigidity. The welded structure hydraulic press used for stamping has good rigidity, open front and back, but closed left and right. In the vertical four-column free casting hydraulic press with upper transmission, the oil cylinder is fixed in the upper beam, the plunger is rigidly connected with the movable beam, and the movable beam is guided by the column and moves up and down under the effect of the pressure of the working fluid. There is a workbench that can move back and forth on the beam. The upper anvil and the lower anvil are respectively installed under the movable beam and on the work table. The working force is received by the structure composed of upper and lower beams and uprights. Large and medium-sized free forging hydraulic presses driven by pump-accumulators often use three working cylinders to obtain three-level working force. The working cylinder is also provided with a balance cylinder and a return cylinder that exert upward force. These only plan the production principles of hydraulic presses. After thoroughly analyzing these structures, we can have a deeper understanding of hydraulic presses. While continuing to explore new business development models.
