Composition and Design of 400-Ton Vermiculite Board Forming Hydraulic Press
The 400-ton vermiculite board forming hydraulic press is a type of hydraulic press that is compact in structure, quick in action, energy-efficient, and easy to operate, gaining widespread attention. In this design, extensive literature review and dynamic performance simulation software were utilized. Leveraging the structural features of the 400-ton four-column hydraulic press and the PLC control system, energy conversion, regulation, and transportation were achieved through pumps, cylinders, and various hydraulic valves to complete various process actions. This led to the further design of the hydraulic system and PLC system for the 400-ton vermiculite board forming hydraulic press.
Through calculations of hydraulic system pressure loss and temperature rise, the design of the hydraulic system for the 400-ton four-column hydraulic press can meet the sequential cycling requirements of the 400-ton vermiculite board forming hydraulic press, enabling various forming processes such as forging, stamping, cold extrusion, straightening, bending, etc., for plastic materials. The 400-ton vermiculite board forming hydraulic press is mainly composed of the main unit, hydraulic system, and electrical system. The realization of the entire working process of the hydraulic press is first controlled by the electrical system, and then the hydraulic system controls the sequential actions of the main cylinder and ejector cylinder. Overall, the operation of the 400-ton vermiculite board forming hydraulic press is simple, and maintenance is convenient.
The main unit of the 400-ton vermiculite board forming hydraulic press is mainly composed of the upper beam, guide column, worktable, moving crossbeam, main cylinder, ejector cylinder, etc. Specific parameter calculations and working condition analysis were performed to formulate the overall control scheme. After comparing various schemes, the hydraulic control system schematic was drawn up. The hydraulic system uses an insert valve integrated control system, known for its good sealing, large flow capacity, and low pressure loss. To address the issue of insufficient oil supply during the fast forward of the main cylinder, an oil replenishment tank is installed on the top of the main unit for oil replenishment. The speed switching and safety stroke limitation of the main cylinder are controlled by stroke switches. To ensure the forming quality of the workpiece, a pressure-holding circuit is set in the hydraulic system, stabilizing the workpiece during forming. To prevent hydraulic shock, a pressure relief circuit is included in the system, ensuring the safe and stable operation of the equipment. Additionally, the 400-ton vermiculite board forming hydraulic press has an overall layout design for the hydraulic station, and important hydraulic components undergo structural, dimensional, and process design. Brief design is also conducted for the main unit and electrical control system.
Advantages of the 400-ton Vermiculite Board Forming Hydraulic Press:
1. Can conveniently and flexibly configure various components of the hydraulic transmission according to customer needs.
2. The 400-ton vermiculite board forming hydraulic press is lightweight, small in size, has low inertia, and reacts quickly.
3. Convenient operation control, achieving a wide range of stepless speed regulation (speed regulation range up to 2000:1).
4. Overload protection can be automatically realized.
5. Generally uses mineral oil as the working medium, with self-lubrication of relative moving surfaces, resulting in a long service life.
6. Linear motion is easy to achieve.
7. The 400-ton vermiculite board forming hydraulic press is easy to automate, employing electro-hydraulic joint control. It not only achieves a higher degree of automatic control but also allows for remote control.
8. The equipment has a compact structure, occupying a relatively small floor area, saving plant space.
9. The 400-ton vermiculite board forming hydraulic press adopts a four-column guiding structure, precise positioning, stable performance, and avoids the occurrence of pressing deviation or mold damage.
10. By changing molds, the press can achieve the pressing of products in various shapes and sizes, providing versatility.
The 400-ton vermiculite board forming hydraulic press is a powder forming hydraulic press independently designed and produced by the company. It adopts a four-beam four-column dual-cylinder structure design, and the electrical control system is equipped with servo and industrial touchscreen PLC automatic control. A displacement sensor is installed on one side of the crossbeam, and the system has a position exhaust function. The exhaust stroke position is set based on the compression ratio and working stroke of the powder-formed product, and all signals and data can be set via the touchscreen. The electrical control system is integrated into the power cabinet, with an external movable operation console connected via aviation plugs for a neat appearance, easy maintenance, and convenience of use. The interfaces of the pressure oil pipes use SAE flange connections, ensuring strong fastening and avoiding oil leakage. The ejecting force of the lower ejector cylinder is large, with both the main cylinder and the lower ejector cylinder being 400 tons, bidirectional pressure, and the lower cylinder is equipped with a 40-ton core pulling cylinder device, and the core pulling stroke can be customized according to customer product requirements. The 400-ton vermiculite board forming hydraulic press can be equipped with safety protection light curtain devices and emergency stop buttons, ensuring high safety.
