Explosion proof vulcanizing machine is an explosion-proof electric vulcanizing machine used in mining and other explosive gas environments. It is a special portable lightweight vulcanizing equipment for the vulcanization and bonding of conveyor belt joints in the coal industry. It has the characteristics of small size, light weight, easy disassembly and assembly, fast heating, uniform temperature, safe and reliable operation. It is an ideal equipment for canvas, nylon, and steel cord tape joints.
1、 To ensure the normal operation of explosion-proof vulcanizing machines in production, it is necessary to strengthen shock absorption measures
1. Thickening the cushion plate on the workbench: Adding a certain thickness of cushion plate between the explosion-proof vulcanizing machine workbench and the lower mold can move the working stroke of the moving beam upward, thereby reducing the volume of the upper chamber of the working cylinder in case of sudden load loss, and correspondingly reducing the stored liquid elastic energy.
2. Add movable pads on the vulcanizing machine. Install a movable pad between the working cylinder piston and the moving beam of the vulcanizing machine to reduce the volume of the upper chamber of the working cylinder when the material breaks, and correspondingly reduce the stored elastic energy.
2、 The three commonly used sealing materials for explosion-proof vulcanizing machines are polyurethane rubber, oil resistant rubber, and polytetrafluoroethylene.
1. Polyurethane rubber is a new type of rubber material widely used in various hydraulic cylinders, with excellent physical properties and chemical stability. It has good strength, elasticity, and oil resistance, as well as wear resistance. Capable of withstanding high pressure.
2. Oil resistant rubber and cloth rubber: Nitrile rubber is commonly used and has good elasticity
3. Polytetrafluoroethylene (plastic): high heat resistance and good corrosion resistance.
When processing explosion-proof vulcanizing machine accessories, attention should be paid to the high cutting speed and fast wear of the outer edge of the double-edged grinding head, which can grind the double top angle and improve the heat dissipation conditions of the outer edge angle, thereby enhancing the strength of the blade. Drill bit to reduce the surface roughness of small holes. When the diameter of the Fried Dough Twists drill is large, the chip separation groove can be turned over on the front or back of the vulcanizer drill bit. The chip grooves on the front cutting surface have been made during the manufacturing process, and the chip grooves on the main and rear cutting surfaces are both ground off by workers on the grinder.
The working process of the explosion-proof vulcanizing machine is to load the uncured semi-finished product into the model and place it in the gap between two layers of hot plates. The plunger, under the action of hydraulic medium, pushes the movable platform and hot plate up and down, and pushes the movable flat plate to press the mold or product. While performing the above movements, a heating medium is introduced into the heating plate to obtain the pressure and temperature required for the vulcanization process of the model (or product). After a period of time (vulcanization cycle), the product is fully vulcanized.
