Abstract
The invention provides a manufacturing technology for trimming blades. The manufacturing technology comprises the main steps of steelmaking, external refining, electroslag re-dissolving, ingot casting, forging, annealing, shot blasting, cutting and repairing. The processes of the manufacturing technology are simple, operation is easy, and produced trimming blades are sharp, resistant to abrasion, high in rigidity and tenacity and suitable for trimming and cutting.
Description
Technical field
The present invention relates to blade production technology, particularly relate to a kind of manufacturing process of trimmer blade.
Background technology
Blade comprises the blade part referring to non-hilt; Be contained in the stalloy of shaving in insurance knife rest; Be contained in the sheet cutlery being mechanically used as to cut.Blade is divided into a lot of type, as circular knife and circular shear blade.The circular shape of profile, general circular knife is applied in plant equipment, mainly cuts, the machining functions such as deburring.Circular knife all has interstitial hole usually, and object to make it be fixed in plant equipment, thus reach cutting function.Wherein also have a lot of money circular blade edge to be dentation (flat tooth, pointed tooth, irregular dentation), the edge of a knife put the first edge on a knife or a pair of scissors two-sided, one side, do not put the first edge on a knife or a pair of scissors three kinds.Slitting blade is mainly used in paper, film, gold/silver foil, cutting of the article such as aluminium foil, Copper Foil, tape, and require that blade cut-out resistance is minimum, mar proof is maximum.Sometimes micron accuracies must be reached for the requirement cutlery of commodity precision.Razor blade stock is widely used in pottery, printing machinery, paper industry, carton, forestry, rubber, plastics, food machinery, light textile, electrical equipment, light industry and machinery, aluminium foil, metalized film, tobacco, cigarette machinery, packaging material, film, electronic apparatus, electric wire, cable, shipbuilding, chemical fibre, glass, weaving, feed, paper tube, forestry, woodworking machinery, plastic crushing, banding, middle envelope machinery, bottom-sealing bag-making machine, timber is processed, packaging for foodstuff, papermaking aluminium foil is cut, metallurgical dynamo-electric, medicinal material, the various industry such as rubber.Therefore the development of following blade industry will be very good.
Summary of the invention
The invention provides a kind of manufacturing process of trimmer blade.For realizing object of the present invention, technical scheme of the present invention is as follows:
