Abstract
The present invention relates to a cutter group used for sewing machine, it provides a suture or a cutter group cut by sewing cloth, the cutter group includes a fixed lower cutter and a movable upper cutter, one end of the fixed lower cutter and one end of the movable upper cutter both have a relative cutting edge separately; the fixed lower cutter is the mirror finishing and polishing surface and is fixed on a holder, and the cutter of the movable upper cutter also is the mirror finishing and polishing surface and is fixed on a movable base rotating around a axle, in addition the cutter of the movable upper cutter has a opposing touching end which is close to the upper of the fixed lower cutter to make the backward and forward rotation of the movable base rotating around a axle drive the movable upper cutter sliding back and forth with respect to the upper of the fixed lower cutter, the cutting edge forms folding movement and the purpose of cutting suture or being sewed, so it can reduce the loss caused by cutter groups mutual friction effectively.
Description
Technical field
The present invention relates to a kind of use in sewing machine cutting knife group, particularly relate to and a kind ofly block thread or by the cutting knife group of sewing cloth.
Background technology
Industry is the most normal metal that is used to iron and steel for Sewing machines, and in its most spare part (cutting knife group) application, has enough intensity and reliability.And ferrous materials is based on ferro element, adds some elements again, as carbon, silicon, manganese, nickel, chromium, molybdenum, tungsten, vanadium, titanium etc.These iron-based alloys, character are very extensive, and at first, the present invention's carbon steel and steel alloy just commonly used earlier compared.
Carbon steel, according to the number of phosphorus content can be divided into one, mild steel; Two, medium carbon steel; Three, high-carbon steel:
One, mild steel: phosphorus content is lower than 0.3% steel, because its phosphorus content is less than 0.25% usually, is unresponsive for the heat treatment that forms marquensite therefore, and the reinforcement of its steel mainly is to finish by cold working.Can be used as body of a motor car and protective plate materials, make structure and other parts that needs carburizing of bridge and building, also can be used for the bolt of production automobile frame and cold forming.
Two, medium carbon steel: the steel of phosphorus content in 0.3%～0.55% scope, these steel can be by Austenitizing, and hardening heat treatment such as tempering is then improved engineering properties, the most often uses with the Annealed Strip attitude, and its microstructure is a tempered martensite.Then can be used for some need improve the goods of hardness to prevent to wear and tear by increasing carbon content, and as cutter, agricultural tool also can be used to make the spring of various kind.
Three, high-carbon steel: carbon containing is higher than the steel more than 0.55%, for the hardest the strongest in the carbon steel, and the poorest person of ductility, wherein the tool die steel is representative, they almost always use with sclerosis and tempering situation, and so special mode is that the workpiece that is the production abrasion performance uses.
Steel alloy is meant and adds the formed steel material of one or more alloying elements in the carbon steel, and the steel material is added nickel, chromium, vanadium, molybdenum etc. according to different purposes.According to the addition element kind, be called the monobasic steel as only adding a kind of element, for example: nickel steel, molybdenum steel; Add two kinds of elements and be called the binary steel, with the content of alloying element, steel is except carbon, if contain other element that surpasses trace, for example: Mn measures more than 1.65%, Si amount 0.60% or more or Cu measure 0.06% when above, promptly belong to steel alloy, the case hardness of this steel alloy is higher than high-carbon steel, therefore, the height abrasion cutting knife group on Sewing machines,, then can improve the loss of spare part because of rubbing and caused each other if can use the high-carbon steel or the steel alloy of high rigidity.Therefore, for the abrasion of the height on Sewing machines cutting knife group, how to reduce the loss that rubs and caused because of each other, a real big problem that designs the producer for Sewing machines.
In addition, the inventor also recognizes, the metal surface roughness is only the subject matter that causes the abrasion of cutting knife group in fact, so if the cutting knife group is polished processed, then can reduce cutting knife group surface roughness and reduce mutual to each other abrasion.Surface after the medal polish processed can be divided into bright, minute surface and lousiness face, is the modification processing that utilizes flexible polishing instrument and abrasive grain or other polishing mediums that the metal works surface is carried out.Polishing can not improve the dimensional accuracy or the geometrical precision of workpiece, but is purpose to obtain smooth surface or bright luster.Usually with polishing wheel as polishing tool.Polishing wheel is generally pressed to workpiece with the polishing wheel of rotation at a high speed, makes surface of the work produce roll extrusion and micro cutting, thereby obtains the finished surface (being bright face) of light; And minute surface can be removed the surplus of 0.01 millimeter, and purpose is to reduce surface roughness, and its surface roughness generally can reach R
a0.63～0.01 micron.And after continuous high speed rotation polishing wheel essence is thrown a few hours, can obtain the surface (being the lousiness face) of dazzling light, its surface roughness is not more than R
a0.01 micron does not observe any blemish, its surface roughness minimum at the microscopically that amplifies 40 times.
For the Sewing machines that need are used for a long time, the sharpness that its cutting knife group cuts is the principal element that influences product quality and man-haur efficiency.In sum, influence sharpness that the cutting knife group cuts as can be known and must see the abrasion hardness of this cutting knife group and surface roughness thereof; Therefore, how to reduce the loss problem that the cutting knife group rubs mutually and caused, the problem that needs to be resolved hurrily for the present relevant industry of Sewing machines.
This shows that above-mentioned existing sewing machine still has many defectives with the cutting knife group, and demands urgently further being improved.In order to solve the problem that use in sewing machine cutting knife group exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing sewing machine exists with the cutting knife group, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of founding a kind of novel use in sewing machine cutting knife group, can improve general existing sewing machine cutting knife group, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
