摘要
The Design of the Pipe Bender  Expressure Experiment Machine Control System
——Control System Section
Abstract
The Pipe Bender experiment machine is profession heavy duty machinery equipment in the machine manufacture, is one of symbols that weighs a country machine manufacture level and ability. Bending machine as the main distributor of the ponents of its design and scientific rationality to the bending machine of the overall performance of the mentioned. The design and manufacture of our country forging pump press has experienced the process which the study,imitates unceasingly improving.
The paper introduces the principle of the Pipe Bender experiment machine, analyses the position , The operating results are fully approved. PLC in adverse circumstances than the relays, contacts with safe, reliable, durable. To hydrostatic testing machine programming controller programming for example, on a hydraulic, pneumatic, electrical system under the joint control of programmable design methods.
Keywords: Pipe Bender experiment machine, programme-logic Controller, control system
