Extruder operators must pay attention to the following matters before formal operation to ensure normal, safe and continuous production.
(1) Check whether the equipment is normal, whether the operating parts of the machine are in place, the lubrication of the slide plate, whether the travel switch of the sensing device operates, whether fasteners (screws), etc. are loose, whether the circulating cooling water is turned on, and whether the oil level is sufficient. , whether the oil temperature is normal, whether there is any abnormal noise from the oil pump, whether the working speed is normal, and whether the action conversion is normal.
(2) Check the condition of the rod furnace (refer to Article 1), check the extrusion center line, check the heating of the extrusion barrel, and the fluctuation of the heating instrument. The operation status of tractor, material bed and rear equipment. Whether all kinds of operating equipment and maintenance hardware tools (molds, pads, pressure cakes, pressure plates, clamps, hammers, pliers, wrenches, screwdrivers, screwdrivers, crowbars, heat-insulating strips, shaping tools, etc.) are in fixed positions at the work site , driving, whether the mold heating furnace is normal. Whether various quenching cooling fans are running. Whether the various measuring tools are complete and correct.
(3) Whether there are irrelevant personnel on site, whether there are maintenance personnel, whether there are inspection personnel, whether there are new students, aluminum profiles should dissuade and inquire relevant personnel respectively based on the actual situation and the principle of safety first, Prompts, preventions, explanations, training, guidance, demonstrations, etc., and keep confidentiality of outsiders without leadership when necessary. Coordinate production according to schedule, team members, pay attention to the orderly connection between each process.
(4) Understand the production content, production requirements, and production sequence, make corresponding real data records during production, write clearly and clearly, mark the production date, and make it verifiable, traceable, learnable, and quotable. The drawings, forms, information, documents, etc. for the production of profiles must be prepared in advance and be familiar with them.
