1, the main mechanical parts such as connecting rod, crank gear on the movement of vice, is made up of copper set of sliding bearing, easy to wear, impact on the accuracy;
2, up and down mould clamping force is uneven, for dual-mode tyre vulcanizing presses, two side force, the force of more than two inside;
3, upper and lower parallel degree, coaxial degree of the hot plate, manipulator jaw roundness and alignment of hot plate inner hole, such as precision level is low, especially the repeated low accuracy; Clamping force is crank pin to bottom dead center moment decided by each mechanical components elastic deformation, the temperature stress component size will vary, the mould clamping force also will change, so in the process of production, temperature fluctuations will cause mould clamping force. On the hydraulic vulcanizing machine structure has the following characteristics:
1, the body is the framework of fixed type, compact structure, good rigidity, small deformation under large clamping force, is advantageous to the tire life and tire quality. Although the hydraulic vulcanizing machine is double cavity, but from the mechanical point of view, only two single-mode vulcanizing machine linked together, under the effect of clamping force, the frame of tiny deformation is mould center line of symmetry;
2, smooth the action quickly, greatly reducing the vulcanizing machine auxiliary time.
3, high precision machine, greatly improve the precision of tire forming. On the movable die, mould parts for vertical movement up and down, only to keep high in accuracy and repeat precision; To keep active, on the other hand, the precision of the die are favourable;
4 force uniform, upper and lower clamping force, and is not affected by temperature;
5, the machine of each frame can match a set of control system, can be individually control, work independently;
6, the action is simple and effective, the user use process, basically no wearing parts, spare parts need to change, also do not need mechanical vulcanizer as regular long, overhaul, greatly reducing the user cost and increase the equipment utilization rate.
