China's sheet bending forming equipment has made a major breakthrough

<

On December 14th, the National Science and Technology Major Project – 30000kN×14000mm full-closed high-precision servo bending machine was launched in Hubei Sanhuan Forging Equipment Co., Ltd., marking the high precision and high reliability of China's sheet bending forming equipment. The development of intelligent bending direction has filled the gap in China's technical equipment field and can meet the urgent needs of large-scale and high-end CNC bending machines in the automotive, shipbuilding, energy, electric power and engineering machinery industries.
The full-closed high-precision servo bending machine has the characteristics of full closed loop, high precision, high efficiency, wide process range, convenient and safe, and pleasant, and its key technical performances such as structural stability, geometric precision, workpiece precision and automation. The index has reached the technical level of the international high-end CNC bending machine, which can fully meet the requirements of high-precision bending forming of large-size high-strength sheets.
In the subject of implementing the national high-end CNC machine tools and basic manufacturing equipment technology special project "30000~65000kN full-closed high-precision servo bending machine", Sanhuan Forging Co., Ltd. is aiming at the world's technological frontiers, gathering elites, carefully organized and carefully implemented. Strengthening the cooperation of "production, learning, research and use", carrying out deep integration innovation and original innovation, and conquering a series of key technologies with independent intellectual property rights, and achieved a number of major achievements. Such as the successful development of the domestic laser online detection, full-length multi-point intelligent compensation system and full-loop bending control, to achieve high-precision bending of high-strength sheet, the precision of its parts is much higher than the similar products at home and abroad; innovative design The heavy-duty internal force balance automatic variable pitch bending lower mold, the quick change upper mold mold base, and the adaptive large-size bending part support mechanism are all new technical achievements applied on the bending machine for the first time; novel compensation A multi-point independent convex device for bending plate thickness and material difference accurately compensates for the local angle difference caused by the plate error and realizes high-precision bending; the self-developed high-strength plate bending forming process software fills the domestic blank. A major breakthrough has been made in theory.
The successful development of the full-closed high-precision servo bending machine has enabled China's bending forming technology and equipment to reach the international advanced level and improve the international competitiveness of China's forging equipment.

The series FFB Tow-Piece,Floating Ball Valve 1/2"-6" ANSI Class 150-600,1/2"-2" ANSI Class 900-1500,1/2"-1" ANSI Class 2500 in full and reduce port

Design Features

ZC standard floating ball valves are manufactured in tow pieces bolted body,ball valves could be supplied full or reduced bore,designed for maximum rigidity against pipeline thrust,made from forged components or barstock.

Bolted body constructions allow easy service and maintenance opration on site,Pressure rating is from class ANSI 150 up to ANSI 2500 Lbs.

Valves are usually supplied with lever operator,with gear box or bare stem on customer request. All standard floating ball valves have below features:

  1. Lock device:valve is equipped iwth an integral locking device to secure line flow.
  2. Blow-out proof stem:the stem is made separately from the ball with integral T-type round shoulder,which ensures total safety and integrity.
  3. Anti-Static Design:grounding device are supplied form positive anti-static between ball/stem and body.
  4. ISO 5211 mount plate:simplifies the installation of actuators with standard connections.
  5. Emission-free gasket:the primary gaskey is emission free graphite to eliminate leakage.

Fire Safe Design

ZC Ball Valve have acquired API 607 certification,Fire safe is standard desing on all ZC Ball valves,

When fire burned out the primary O-ring and seat insert,the secondary seat fire-safe packing graphite seal,and seat ring & ball metal to metal contact preloaded by spring will minimize the internal process medium leakage.
