The type JY radial presses are the equipments which was designed specially for the needs of crimp connection production of high- The type JY radial presses are the equipments which was designed specially for the needs of crimp connection production of high-voltage suspended compound isolator, with max pressing force 6000kN. Besides, the pillar and cross arm of small specifications also can be pressed on the radial press. This radial press must be operated by special persons and provided with exclusive maintenance personnel. Operating and maintenance must be trained, and the all contents in the operating instructions must be read carefully and mastered familiarly by operating and maintenance personnel, only after one is conformed to requirement, he will be on the post. The operator particularly conform to the every regulation in the instructions section 12 "the requirement for safety operation". The single oil cylinder on this radial press will be used for power fittings which loaded with pressure and crimp connection can be performed via cone bushing, so that not only the radial press can be worked with synchronization and higher accuracy, but also the maintaining work of cylinder and piping are greatly reduced oil. Cylinder is a key part. On this press the cylinder, piston rod and seal part with imported high accuracy wear-proof was used so that make sure that good sealing performance and very high working life. Both amount of pressing and pressing pressure are sued to control the press quality at the same time. Therefore under the same condition, the pressing effect for the maximum tensile loads and the minimum discreteness are obtained. Thus there is also more improvement effect for defect of different the pressing quality, which was resulted from different hardness of power fitting of ball head and ball socket. Under the more condition for quality consistency of power fittings and core bare, the amount of press or pressing force can be used singly on this radial press to control pressing quality. The functions for "amount of press""maximum limit pressure", "minimum pressure" and "pre-pressure" etc was set up on this radial press for the isolator of different specification, the different value can be chosen and showed randomly in the pressing procedure. When the "maximum limit pressure" is chosen, the over load pressure can be prevented from the core bare to be damaged. The tensile load less can be avoided by "minimum pressure". When "pre-pressure" was used, before pressing formally, at first the machining error of outside diameter of power fitting and the gap between the power fitting and core bar will be eliminated, and then the press procedure will be performed according to the setting amount of press, therefore make sure that the stable amount of press and the amount of work which power fitting and core bar was chosen and fitted by production factory was more reduced. In control and detection system of radial press, the "acoustic emission detection system" was provided, by which it can shown that real time curve of the acoustic emission energy rate and time as well as curve of corresponding oil cylinder pressure and time. It can be judged automatically that if there is a core bar being damaged in every press procedure, as well as the press quality is shown in the intuitive way of sound and color. The data of parameters, figures and distinguish result can be restored, replayed and printed for each time of the pressing. There are big external oil tank with oil cooler on the machine, so that it can be assured that the production of machine be run continuously even in hot summer.
