Aph-125 series gantry precision four guide pillar press
The structure of high steel alloy casting frame (the most suitable frame is designed by computer analysis) is further improved by eliminating the internal stress process, which is indispensable for the accuracy of the high steel frame. The low noise and low vibration are realized, and the service life of the die is improved.
APH series has 9 models in total
High speed punch adhering to the "high speed, precision, long service life" design concept. High strength cast iron is adopted as a whole, and stress relief is carried out to ensure long-term accuracy, no deformation during long-term operation, and control of overlapping accuracy of bottom dead point, so as to improve the stability of operation. For the connection between the frames, screw is used to fasten and add pressure force to preload the frame structure to improve the rigidity of the frame.
A. The main shaft is made of alloy steel and processed by heat treatment and grinding. The balance weight at the eccentric part of the spindle is integrated with the spindle, which requires good strength and long service life;
B. The crankshaft adopts forced cooling system, and the crankshaft is cooled and lubricated;
C. A lubricating oil port is opened in the center of the crankshaft to ensure the effectiveness and reliability and reduce the failure rate.
The slide block is guided by axial bearing without clearance. The relative position and size of each part and body must be accurate. The hardness of the matched parts must be above hrc58 ° with high manufacturing cost, long manufacturing cycle and high process requirements;
