The Designing Of The Automatic Molding And Welding Equipment For The Trusses Which Used In Mines' Shoring

Jinchuan Nickel Mine is the largest undergrounded metal mines, the company's nickel output accounting for 90% in our nation ,.The Jinchuan company located in Jinchang city , because the city rich in nickel, it has known to the wold for nickel city. However, when the company expand the production of nickel further, they have to do with the lowly efficiency difficult in the process of production.through actual inspectin in the company,we found that people need a large number or supporting truss in the process of mining ore.but Jinchuan Group make the truss throng the old method at present.for example:they used to artificial welding methods,which increase workers intensity and make the conditions worse.at the other hand ,the raw materials and energy waste quite strong,especislly on the electrode waste very alarming.thirdly there is different in the quality of welding truss,it bring great inconvenience on the following use.considering above shortcomings,we intend to design an automatic molding and welding eqipument,which could keep the quality or welding and welding process to achieve industrislized production.which also make the quality of welding more desirable.This automatic welding equipment solve the order of welding power grid to prevent pollution and non-straight long tendons material automatically sent to and accurate positioning.It also give the design of the mine supporting truss with the automatic production lines for welding.the machine make up of PLC technology,microcontroller technology, automation technology, welding, gas (liquid) pressure technology and PC technology, integrated configuration.The machine reduce the labor intensity of the workers to a large extent;We also abandoned the manual arcwelding method to reduce the environmental pollution and improve the working environment for workers;It due to resistance spot welding and resistance welding method in the production process saves. The electrode power also reduce the cost of production truss and save a lot of labor, thus could enhance the company's products in the market competitiveness.This subject meet actual production as a main point,it also give the whole process of design options for truss forming welding equipment.The subject is designed as a small welding production lines,which include mechanical parts and control parts. In my design,welding method used mainly resistance spot welding and butt welding,molding process is a hard thrust cylinder shape, right triangle rings taken special molding.We adapt the programmable controller(PLC) as control parts, Finally, this paper use MATLAB software to do manipulator positioning system simulation in the actual design and debugging on the basis of the scene, its purpose is to enable simulation manipulator ideal location process which can achieve in theory. It also can determine the parameters in the controller in theory.
