Hydraulic vulcanizing machine is a specialized equipment for vulcanizing and bonding of conveyor belt joints. The device is made of lightweight aluminum alloy material, with a small volume and light weight per piece. It is powered by an imported three-phase power supply, with uniform temperature of the hot plate and uniform pressure supply from the water pressure system. It is equipped with a lightweight electrical control box, which is connected to the main unit through an integrated plug-in and multi-core cable. The operation is convenient and reliable. It also has the characteristics of fast heating, uniform temperature, and high thermal efficiency. Hydraulic vulcanizing machine is an indispensable auxiliary equipment in current tape transportation machinery.
Performance Introduction:
1. PLC and HMI control can achieve manual and automatic control. Automatic control can achieve functions such as mold closing, exhaust, temperature control, vulcanization timing, alarm, mold opening and unloading; The touch screen displays the real-time temperature of each heating zone on the hot plate.
2. Mold opening assistance mechanism: During mold opening, the four oil cylinders located under the platform are activated to forcefully pull down the platform, preventing the phenomenon of sticking to the pot and unable to open the mold.
3. The hot plate edge adopts hydraulic automatic top iron, and the pad iron on both sides of the hot plate moves forward and backward simultaneously under the action of four oil cylinders; Both ends of the hot plate are equipped with anti pad iron overlap devices.
4. Each heating zone of the hot plate is equipped with a set of temperature regulating valves, which are controlled by PLC to ensure uniform and consistent temperature in each heating zone of the hot plate. Can achieve automatic: mold closing, exhaust, mold opening and unloading.
5. Mold closing guide device: There are mold closing guide devices on both sides of the underlying platform, and guide seats are installed on the frame plate and platform. The guide seats are machined with inclined surfaces, and the distance between the inclined surfaces can be adjusted by threading.
6. Mechanical synchronous balancing mechanism: There is a synchronous shaft that runs through the unit below the platform, and gears and racks are installed at both ends of the shaft to ensure the horizontal lifting and lowering of the platform.
Structural characteristics of hydraulic vulcanizing machine:
1. The hydraulic vulcanizing machine body is a fixed frame type, compact in structure, with good rigidity, and small deformation under large clamping force, which is beneficial for tire life and tire quality. Although hydraulic vulcanizing machines are also dual-mode chambers, from the perspective of force, only two single-mode vulcanizing machines are connected together. Under the action of clamping force, the slight deformation of the frame is symmetrical about the centerline of the mold;
2. Each action is fast and smooth, greatly reducing the auxiliary time of the vulcanizing machine;
3. The machine has high precision, greatly improving the accuracy of tire shaping. When opening and closing the mold, the upper part of the mold only moves vertically up and down, which can maintain high alignment accuracy and repeatability accuracy; On the other hand, it is also advantageous for maintaining the accuracy of the active mode;
4. The upper and lower clamping forces are evenly distributed and not affected by the working temperature;
5. The left and right racks of the machine can each be equipped with a control system, which can be controlled independently and work independently;
6. The various actions of the device are simple and effective. During user use, there are basically no vulnerable parts, spare parts need to be replaced, and there is no need for regular maintenance or major repairs like hydraulic vulcanizing machines, greatly reducing user operating costs and increasing equipment utilization.
The quality of the joint of the hydraulic vulcanizing machine tape directly affects the working efficiency and service life of the tape, especially in the current long-distance high-strength conveyor belts. The vulcanization insulation time of the hydraulic vulcanizing machine can be adjusted according to the thickness of the belt, using a fully automatic and accurate digital display control system. The vulcanization temperature is uniform and accurate, the vulcanization pressure is uniform, the whole machine is lightweight, reliable, and durable. The rapid water cooling time is 15 minutes, and the heating time from room temperature to vulcanization temperature does not exceed 25 minutes;
