Which high precision press is best?
The body of the high precision press determines whether the press runs stably, requires high wear resistance and impact resistance, and requires strict casting process.
The body weight of the high precision press accounts for more than 60% of the weight of the whole machine. The body of the high precision press directly determines the performance of the press. The fuselage is suitable for the pressing and mounting of shaft and sleeve parts and the stretching, bending, forming, blanking and other processes of simple sheet metal parts.
Zhejiang Yitian Precision Machinery Co., Ltd. has always respected the rigid and high-precision fuselage, using computer three-dimensional design, optimized processing after finite element analysis, to ensure the rigidity of the high precision press fuselage and the angular stiffness of the C-type machine tool. It has many advantages such as high operation accuracy and long service life.
The fuselage adopts an integral welding structure and adopts carbon dioxide gas shielded welding. The parts are precisely polished before welding to ensure welding accuracy. After welding, the welding seam is inspected by flaw detection. The welding seam of the gear transmission box is mainly inspected, and the oil tightness test is done. After welding, do tempering treatment, and after tempering, the surface is shot blasted to remove oxide scale (the company is equipped with a large-space natural gas tempering furnace and shot blasting room) to further eliminate welding stress and ensure the processing accuracy of the fuselage. The body processing adopts the world's advanced PAMA machining center, one-time clamping, to ensure the dimensional accuracy of the body processing and the shape and position accuracy of various parts, which greatly improves the operating accuracy and service life of the press.
The high precision press fuselage castings are made of high-strength steel to ensure the stability of the fuselage components under long-term operation, prolong the service life and reduce the amount of angular deformation.
The high precision and high rigidity high precision press body can not only extend the service life of the high precision press but also improve the running accuracy of various parts in the body. It is also the basis for the proper coordination of all high-performance components, the guarantee for the high-performance operation of the entire machine, and one of the basic elements to win the trust of the majority of users.
