Machine tool bearing packaging principle and material introduction
Machine tool bearing packaging Abstract: Bearing outer packing part bearing manufacturing finished inspection for cleaning rust prevention treatment into the packaging to use convenient maintenance quality precision bearing waterproof and moistureproof and dustproof shock the sales objective bearing rust into rust antirust packing is suitable for bulk shipments into use short-term bearing the same subscribers 2002: the principle of mutual agreement convenient use easy packaging machine, The wto is a challenge but also opportunity experts point out that to strengthen research and development of CNC machine tools in our country to speed up the development of the popular type segment in the machine tool talk at random service competition in the machine tool manufacturing industry in China the status quo of Chinese milling machine and machining center market development direction and prospect of the technology level of domestic and international lathe and machining center production, demand and development trend of world machine tool numerical control system development trend of world development trend both at home and abroad Development of cutting technology and CNC machine tools.
Machine tool bearing packaging is divided into inner packaging and outer packaging.
After the machine tool bearing is manufactured and inspected, it is cleaned and rust-proof, and then put into the inner packaging, in order to achieve waterproof, moistureproof, dustproof, anti-impact, maintenance of bearing quality and accuracy, as well as the purpose of convenient use and sales.
Machine tool bearing inner packaging is divided into three categories according to rust prevention period:
① Short anti-rust period packaging: anti-rust period of 3 to 6 months, suitable for mass shipment to the same subscriber, in a short period of time will be put into use bearings. By mutual agreement, simple packing will be adopted for convenience. (2) General anti-rust period packaging: anti-rust period of one year, suitable for general purpose bearings. (3) Long anti-rust period packaging: anti-rust period of two years, suitable for special and precision bearings.
Machine tool bearing inner packing materials are polyethylene plastic tube (box), kraft paper, plain and wrinkle polyethylene composite paper, paper box, POLYETHYLENE or polyethylene plastic film, nylon fastening belt or plastic woven fastening belt, waterproof high-strength plastic belt, hemp bag, etc. The above materials shall be guaranteed to pass the corrosion resistance test.
Principles and requirements for the inner packing method of machine tool bearings:
① Bearing of miniature machine tool: every 10 ~ 15 sets of bearings are loaded into a plastic cylinder, and every 5 ~ 10 plastic cylinders are loaded into a paper box (or bag, roll package). (2) Medium and small bearings: multiple sets of bearings are rolled with polyethylene film, kraft paper or polyethylene composite paper; Multiple sets of bearings are loaded into a plastic cylinder (box); A single set of bearings are packed in a polyethylene film bag, folded or sealed into a paper box after the bag opening.
③ Large machine tool bearings:
Packing with polyethylene film or polyethylene composite paper sheet, and then into a carton; Use polyethylene film bag, pack folding bag mouth in a single set, and then put into a carton; Single set into special plastic box; Single set of three layers: polyethylene film tape or composite paper tape for inner layer, fastening tape for middle layer, waterproof permeable plastic tape for outer layer.
④ Bearings for oversize machine tools:
A single set of three wrapping packages (same as above); Single four wrapping: After the above three wrapping, wrap another layer of linen tape for the outermost layer.
For detachable tapered roller bearings with an outer diameter greater than or equal to 150mm, polyethylene film should be lined before packing the inner and outer components, or the inner and outer components should be separately packed. For interchangeable cylindrical roller bearings with outer diameter ≥150mm, they can be packed separately by internal and external components because of their easy damage in complete package.
General materials and requirements for outer packaging of machine tool bearings are as follows:
(1) Double corrugated cartons, each carton gross weight (gross weight) not more than 25kg, the box with plastic packing belt binding; Nailed board cases (wooden cases), the total weight of each case is not more than 30kg, and the boxes are bound with blue steel bands. Calcium plastic corrugated box, the total weight of each box is not more than 25kg, the box love to use plastic packing belt bound.
When packing machine tool bearing products with inner packaging into the box, the box should be lined with plastic bags or plastic films; If there is a gap in the box, it needs to be filled with dry materials such as corrugated paper block and paper scraps.
