Big size frame structure presses

Structural form and characteristics

1. Characteristics of frame structure

The frame of the frame vulcanizing machine is composed of multiple frame plates, forming a closed frame structure. This design has the following characteristics:

-Reasonable force distribution: The upper crossbeam has a reasonable force distribution, which can reduce the weight of the equipment

-* * Allow large diameter hydraulic cylinders * *: It is allowed to install hydraulic cylinders with larger diameters at a certain center distance, which can reduce the number of hydraulic cylinders

-* * Simple structure * *: Simple manufacturing and installation, concealed pipeline configuration, neat and beautiful appearance of the whole machine

-Good lateral stiffness: Although the lateral stiffness of a single frame plate is worse than that of a column, the whole machine has sufficient lateral stiffness when multiple frame plates are combined

2. Form of suppression

Frame vulcanizing machines often adopt a downward (upward) pressing form:

-Rising (mold closing): The plunger rises under the pressure of the working fluid, driving the hot plate to close and apply pressure to the product

-* * Lowering (mold opening) * *: Relying on the weight of the hot plate, platform, and plunger, the working fluid is driven back to the storage tank to achieve lowering and opening

3. Core components

The main components of the frame vulcanizing machine include:

-* * Piston and working cylinder * *: Made of ductile iron to improve compressive strength and wear resistance

-Sealing device: Use oil resistant rubber sealing rings to ensure that the working fluid does not leak

-Hot plate system: including upper heating plate, middle heating plate, and lower heating plate, used to provide vulcanization temperature

-* * Rack structure * *: composed of upper crossbeam, frame plate, and movable platform, etc

-* * Insulation system * *: reduces heat transfer to the hydraulic system and protects the oil cylinder

application field

The frame vulcanizing machine is mainly suitable for the production of the following products:

rubber products

-Large rubber bearings

-Large rubber sealing ring

-O-ring seal

-Conveyor belt, flat tape

-Rubber sheet, rubber pad

-Mining accessories

-Automotive rubber parts

-Industrial rubber spare parts

Selection suggestions

When choosing a frame vulcanizing machine, it is recommended to consider the following factors:

|Factor | Explanation|

|------|------|

|Product specifications | Select hot plate specifications based on the maximum product size|

|Mold clamping force requirement | Calculate the required pressure based on the product area and rubber hardness (refer to unit surface pressure of 20-35kg/cm ²)|

|Working layer | Single layer is suitable for large products; Multi layer is suitable for efficient production of small and medium-sized batches|

|Heating method | Electric heating is flexible and suitable for small and medium-sized batches; Steam heating is suitable for continuous large-scale production|

|Automation level | Choose manual, semi-automatic or fully automatic control according to production requirements|

|Auxiliary functions | Do you need automatic pushing and pulling of molds, quick lifting, etc|

|Budget cost | Taking into account equipment procurement, energy consumption, and maintenance costs comprehensively|

Non standard customization options

-The clamping pressure, hot plate size, number of layers, and spacing can be designed as needed

-Heating options include electric heating, steam heating, or thermal oil heating

-Safety gratings and guardrails can be configured as required

-Customizable automatic push-pull mold

Key points of equipment maintenance

1. * * Hydraulic system * *: Regularly check the oil level and temperature, observe whether there are leaks in the pipelines, and replace the hydraulic oil every six months

2. * * Hot plate maintenance * *: Keep the surface of the hot plate clean to prevent residual adhesive from affecting heat transfer uniformity

3. * * Sealing Inspection * *: Regularly inspect the oil cylinder sealing ring and replace it promptly if any leaks are found

4. * * Electrical System * *: Check the working status of PLC, temperature control module, and sensors, and clean the control cabinet

5. * * Cooling System * *: If equipped with a cooling system, regularly check the smoothness of the water circuit

6. * * Accuracy verification * *: Regularly check the parallelism and temperature uniformity of the hot plate
