Technical Characteristics 1 Framed type spring compression structure. The mechanism adopts the framed springs to press the sliding plate tightly ,so the interfacial pressure of the sliding plate is constanthomogeneous accurateeasy to set up ,and does not be influenced by the high temperature and artificial factors. When the mechanism is on the working status, the thermal expansion from the temperature changing and the changes from the different operating habits of the workers will be absorbed by the springs, so there is constant homogeneous pressure on the interface of the sliding plates to ensure the mechanism working safely. 2 Door style structure. Close the door of the mechanism, connect the slider with the rod, actuate the hydraulic cylinder to draw the slider and bracket combination to make the wheels go to the working place, the interfacial pressure of the sliding plates will be set up automatically. So the door style structure in which the interfacial pressure of the sliding plate can be set up automatically, is easy to use, and its structure is reasonable and scientific. 3 Pressure homogeneous transforming structure. On the working status, the bracket combination is fixed. Through the rail of the slider and the bracket combination, the force is given to the interfaces of the upper and the lower sliding plate. This kind of pressure transforming structure is reasonablehomogeneous and safe. 4 Spring insulated structure. Considering the impaction of high temperature to the elasticity elements, we adopt particular insulating design and reasonable layout of springs, to make the springs be far from the high temperature zone and reduce the impaction of the high temperature. With the air-coolled device on the mechanism, the operating is safer and more reliable, and the life time is much longer too. 5 The main body of the mechanism is high strength and anti-high temperature material, so the life time is much longer. 6 The elasticity elements are high temperature belleville springs, so it saves time and energy for operating , and it is safe and of high reliability long life time and low cost.
