Rubber press machine advantages
(1) Under a certain center distance, large diameter hydraulic cylinders are allowed to be installed, so as to reduce the number of hydraulic cylinders, and simple structure, less maintenance;
(2) The beam force is reasonable, the required section modulus is far smaller than the column type, can reduce the weight;
The manufacture and installation is simple, the pipeline configuration is hidden, the machine appearance is neat and beautiful.
Rubber press machine characteristics
- The equipment adopts frame type structure. The main cylinder is made of QT500-7 material, and the piston is made of cold-hard alloy cast iron. The maximum pressure resistance reaches 20MPa, with high strength and good wear resistance. Hydraulic system high and low pressure respectively drive control, using 2 set of 7.5KW motor drive.
- the equipment adopts automatic PLC+ HMI controller electrical hydraulic joint intelligent control, automatic intelligent display temperature, curing pressure and curing time can be adjusted; It has the ability of automatic air discharge, the number of air discharge can be adjusted and the air discharge stroke can be adjusted.
- Vulcanizing machine in the process of opening and closing mold, cylinder stroke is larger. When closing the mold, the cylinder is required to close the mold quickly first. When approaching the setting, in order to prevent the inertia forward thrust caused by the excessive speed, the cylinder needs to slow down, that is, slow forward, and then stop in place. After the second setting, the speed of the closing cylinder is also small when the mold is completely closed. In addition, vulcanization is completed, when the upper mold is opened, in order to improve efficiency, the mold should be quickly opened, in order to quickly reach the predetermined position, in order to prevent impact, need to slow down to reach the dead point after locking.
With the development of hydraulic technology, the proportion technology appeared in the late 1990s, because the proportion control has the advantages of excellent dynamic and static characteristics of electro-hydraulic servo system, and simple manufacturing, low price, reliable work, convenient maintenance. Therefore, in the design, for the first time the proportional technology this advanced technology is applied to the hydraulic system, improve the technical content of the product.
