For the same plate thickness, regardless of the width of the plate, the constant pressure is pressed during the entire shearing process. The disadvantage is that the tool holder has an impact when it is descending from the top dead center, but it can be overcome by increasing the balance force or increasing the braking torque. After more than two years of practical use, the structure proves that the material is reliable and fully meets the design requirements.
The diameter of the screw of the friction press is up to the outer diameter of the sound nut. In the overhaul, it is generally necessary to replace the screw nut pair with severe wear. The press is used for about 10 years, the maximum wear of the thread thickness of the main drive nut is increased to the gap of the transmission pair, and the radial working yaw amount between the transmission flywheel and the main friction wheel is reduced from the rated energy to the repeated Argumentation and careful practice, using the process of repairing the old screw with the new screw, finally made the press reach the technical standard after the overhaul.
Correctly check the wear of the nut. Measure the circumferential direction and the up and down direction respectively. The wear amount of the thread thickness is the lower end of the thread. The standard thickness is the lower end. The upper end is the lower end. The upper end is the difference in the circumferential direction of the nut. The wear is poor. The upper end of the inner diameter of the thread is the lower end of the Shanghai, the standard inner diameter of the Shanghai thread is the bamboo shoot, then the inner diameter of the inner diameter is calculated. The upper end is the maximum end. The maximum wear amount of the thread circumference is calculated from the measured data, and the tool used for the inspection side is the tooth. Thick caliper thousand calipers and inner calipers. The components used, except for those imported from Japan, all use domestic components. We have installed a long-term program that can be stored without a battery.
