800Ton Pressure Rubber spring vulcanizing machine / Rubber airbag vulcanization molding machine

Machine introduction:
Air spring vulcanizing machine is a key equipment used in the production process of air springs to vulcanize and mold rubber materials. The following is a detailed introduction:

1. Structural composition:

- Frame part: It is the basic support structure of the equipment to ensure the stability of the entire machine. Common structural types include double-column type and frame type. For example, the double-column air spring vulcanizing machine, its columns play the role of guiding and supporting the upper movable beam, ensuring the smooth and reliable lifting and lowering movement of the upper mold.

- Mold system:

- Upper mold and lower mold: The upper and lower molds are set relative to each other, and a closed space is formed after the mold is closed, which is used to accommodate rubber materials and other parts of the air spring for vulcanization molding. The shape and size of the mold are determined according to the specific specifications and design requirements of the air spring.

- Clamp or splint: Some vulcanizing machines are equipped with a clamp or splint on the outside of the lower mold. During the vulcanization process, the air spring can be pressed against the capsule and other parts from both sides, so that the air spring and the capsule fit more closely and ensure product quality.
- Heating system:
- Heating plate: The upper and lower heating plates are installed on the upper and lower molds, or at other locations of the equipment, to provide the heat required for vulcanization. The heating plate usually adopts electric heating or steam heating, which can quickly and evenly heat the mold and rubber material to ensure the vulcanization effect.
- Insulation device: In order to reduce heat loss and improve energy efficiency, insulation devices such as insulation rings or insulation boards are usually set on the periphery of the heating plate.
- Center mechanism:
- Center big rod and center small rod: The center big rod is usually fixed on the main frame of the equipment, and the center small rod is connected to the center big rod through a guide sleeve. The top of the center small rod can be connected to the inner bag of the air spring, which plays a role in positioning and supporting during the vulcanization process.
- Displacement sensor, proportional valve and pressure sensor: Used in conjunction with the center small rod, the displacement sensor is used to detect the displacement change of the center small rod, the proportional valve is used to control the flow of gas or liquid, and the pressure sensor is used to monitor the pressure change. These components work together to achieve precise control of the vulcanization process of the air spring.
- Cylinder system:
- Main hydraulic cylinder: used to drive the lifting and lowering movement of the upper mold to realize the opening and closing of the mold. The piston rod of the main hydraulic cylinder is connected to the upper mold, and the power provided by the hydraulic system enables the upper mold to accurately close or separate from the lower mold.
- Side hydraulic cylinder and bottom hydraulic cylinder: In some equipment, side hydraulic cylinders and bottom hydraulic cylinders are provided to drive the opening and closing and lifting of the side slide plate, which facilitates the demolding and loading operations of the mold and improves production efficiency.
- Boosting cylinder: Some vulcanization molding machines are also equipped with boosting cylinders, which provide additional pressure after the mold is closed to ensure that the mold is tightly closed so that the rubber material can be fully vulcanized.
2. Working principle:
- Put the pre-processed air spring semi-finished products (including rubber materials, wheel rims, inertia force blocks and other parts) into the lower mold.
- Drive the upper mold down through the cylinder system to close the upper mold and the lower mold to form a closed vulcanization space.
- The heating system starts to work, and the heating plate transfers heat to the mold and rubber material, so that the rubber material undergoes a vulcanization reaction under the action of high temperature and pressure, thereby forming the air spring.
- During the vulcanization process, the central rod of the central mechanism automatically adjusts the position and pressure according to the feedback information of the displacement sensor and the pressure sensor to ensure the accuracy and stability of the vulcanization process.
- After the vulcanization is completed, the cylinder system drives the upper mold to rise, and the side hydraulic cylinder and the bottom hydraulic cylinder drive the side slide plate to open, perform the demoulding operation, and take out the vulcanized air spring product.
3. Advantages:
- High production efficiency: The degree of automation is high, and the automatic opening and closing of the mold and the automatic adjustment of the center rod can be realized, which reduces the time and labor intensity of manual operation and greatly improves the production efficiency.
- Good product quality: Accurate temperature, pressure and time control, as well as good mold closure and heating uniformity, can ensure the vulcanization quality of the air spring, making it have good elasticity, sealing and durability.
- Strong applicability: The mold can be replaced and adjusted according to air springs of different specifications and models, and is suitable for the production of various types of air springs.
4. Application scope: Widely used in suspension systems of vehicles such as automobiles, trains, and airplanes, as well as shock absorbing devices in industrial equipment, construction projects and other fields.
