Recently, the first 1,000 tons of reverse-phase double-acting aluminum extruder independently developed and manufactured in China was formally put into use at Guangdong Chuangkeda Aluminum Co., Ltd., marking that China's aluminum processing equipment manufacturing level has reached a new level.
The metal extrusion machine has the forward extrusion machine and the reverse extrusion machine. Reverse extrusion can produce high-precision, uniform microstructure, coarse grain ring and other high performance requirements of aluminum pipe bar, back extrusion The application has achieved significant benefits.
China's reverse extrusion of aluminum began late. In 1986, it introduced the first 25MN aluminum tube bar inverse extrusion machine from Japan. The Chinese indirect extrusion machines using extruded aluminum are all produced by Ube Japan. UBE), SMS (Germany) and Taiwan Province and other companies.
Guangdong's private-owned company, Weicheng Machine Manufacturing Co., Ltd. began research and development in 2005. In March 2006, it successfully manufactured the first Chinese-built 1,000-ton reverse double-acting aluminum extruder, which was officially delivered to Guangdong Chuangkeda Aluminum Industry Co., Ltd. Use, operation is recognized, in 2007 has been for the new user Shenzhen special aluminum alloy manufacturing plant to re-manufacture a 1000 tons reverse double-acting aluminum extruder. Weicheng 1000 tons reverse double-acting aluminum extruder main technical parameters:
Nominal extrusion force 1000 (MN)
Piercing force 190(MN)
Extrusion speed 0-9.4(mm/s)
Extrusion cylinder diameter 152(mm)
Extruding tube length 450 (mm)
Piercing needle diameter 50 (mm)
Extrusion spindle diameter 148(mm)
Extruded ingot length 350 (mm).
Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.
