Mill-owner of intelligence of digitlization of oil cylinder of project brief introduction should include piston lever product line, crock canister product line and assembly line to wait, covered car, mill, grind, polishing, heat treatment, solder, eletroplate, blow roller, clean, assemble, hit a code to read the of all kinds equipment such as outfit of code, besmear, deserve additionally to the workshop discharges bits, concentration centrally MCIS(of system of informatization of system of informatization of content shedding, enterprise, factory, workshop makes cooling, automation control information) the system. The fundamental compose of intelligent factory becomes numerical control machine tool and automation content to sort equipment. According to demand, use the advanced technique on international and sound program, the CNC facility that has process designing function and long-range data to receive a function and PLC equipment, deserve to go up to discharge bits, concentration centrally content shedding, workshop always accuses cooling, automation the unit such as the system, break stand-alone treatment and artificial content to spread the way of have a change of luck, realize product line thereby automation, intelligence is changed and flexible change a requirement. The implementation of intelligent factory asks besides the hardware such as equipment outside, still need the software such as digital chemical plant, fictitious prototype prop up. Its superstratum is neurological be a workshop advocate control network system, adopt MCIS system, undertake with the equipment on product line information is mixed interactively control, from production order government, content sheds the respect such as management, quality management, equipment management, cutting tool management, unusual monitoring management to achieve informatization administration, the intelligence that realizes a factory finally turns production. 2.

Project characteristic and advanced sex are current product line place is with craft domestic and international more advanced treatment means, crucial working procedure broke through a tradition to machine a method, this also is the window place of product line. Be like: Piston lever dangler solders use friction welding to receive kind, improve manufacturing efficiency greatly not only, and solder the annulus seam welding of quality outclass tradition receives kind; Crock canister flange solders used a robot to solder, while treatment efficiency rises, solder quality also got promotion likewise; Eletroplate use full automatic eletroplate line, of the spare parts eletroplate tradition of quality far outclass eletroplates artificially means; Cleaning machine uses advanced carbolic hydrogen means to replace traditional bath pattern, the exterior cleanness that raised a part not only is spent. And carbolic hydrogen clear lotion can be used circularly, avoid waste of water natural resources to cause an effect to the environment; Assembly line is used automatic and semi-automatic assemble what change equipment to replace a tradition artificially, rise assemble quality while, greatly reduced artificial operation time and the uncertainty that bring artificially. Place should deploy feet of high accuracy grating with the machine tool, overall use full closed-loop control. Cutting kind the machine tool has lock of functional each other, realize 3 axes linkage and interpolation. The machine tool uses system of advanced numerical control, provide long-range control software and software of network edition DNC, in order to realize the long-range control to the machine tool, diagnose and data is transmitted. Deserve to have cutting tool management center, and stock is opposite automatically knife function. Of all kinds equipment all has protection of journey limits control, soft limit, journey protection, UPS to cut off the power the multiple protection function such as protection of protection, pitching moment overload. Production unit has locks of a variety of protective function each other, ensure the person that handles personnel is safe.
