Abstract
The utility model relates to a die device in a mechanical production field, in particular to a die used for producing a thread hole punching angle on a sartorius bobbin case, aimed at solving the problems of pilling and thread break due to the unevenness of the thread hole edge on the bobbin case during using the prior sartorius, and providing a die used for producing the thread hole punching angle on the sartorius bobbin case with the advantages of reasonable structure, evening function for the thread hole edge and reduced damage on the thread caused by the thread hole. The technical problems are solved through the technical proposal that: the die comprises two parts; an upper punch is axially arranged at the bottom of an upper cylinder, which is produced with the upper punch together and then produced for forming a transition arc; and a lower punch is arranged perpendicularly to the axis of a lower cylinder and is embedded into the lower cylinder.
Description
Technical field
The utility model relates to a kind of die device of field of machining, especially relates to a kind of mould of processing sewing machine shuttle putamen stay wire bore ram compression angle.
Background technology
Since the sewing machine invention was come out, people had done continuous raising and improvement to it, and are convenient in operation, improve the sewing efficiency aspect and done many work.Along with making the extensive development of industry, sewing machine is also had higher requirement, wherein the raising of sewing efficiency is one of continuous important topic of pursuing of people all the time, requires more urgent aspect industrial sewing machines.
Because China's Sewing Machine woker is crossed the development of decades already, formed and had considerable scale and certain level, output occupies first place in the world, and world sewing machine producing country mainly concentrates on a few countries and areas such as Germany, Japan, China and Korea S at present.China's industrial sewing machine output maximum accounts for more than 50% of worldwide production.At present, China has become universally acknowledged sewing machine big producing country and has used big country.Simultaneously, China is again maximum sewing machine market, and therefore, famous in the world major company all transfers to China now, along with increasing developed country transfers to China with its stitch machine manufacturing industry, the general layout that China and foreign countries' stitch machine is raced on the same stage highlights day by day.In recent years, that China's stitch machine industry has begun to change is of low grade in the world, quantity is many, low-cost image, and having stepped into the technological innovation is the Rapid development stage of principal character.When establishing independent intellectual property right, by type of production to producing developing transformation, product by copy to create, by low price to high added value, by single variety in enormous quantities to the many kinds development of small lot.
Constantly improve and improve the production technology of sewing machine component, improve and the quality of improving sewing machine component has crucial meaning for sewing machine industry and textile industry, at cost with technically all will surmount external technology by autonomous innovation.
Bobbin case is one of strength member of forming by sewing machine, and the quality of its quality has determined the stability of sewing machine running, the quality of production, the efficient of production; There are a lot of problems in bobbin case always, though can use reluctantly, but very big influence is arranged for production, in the process of using, line is rubbed easily such as the sewing machine bobbin case, wherein chief reason is that the edge in backguy hole is too sharp, as shown in Figure 3, thus make line in backguy hole surface (3a), because stressed excessive being rubbed.
At present, produce problems such as balling-up, broken string in order to overcome in the process of using sewing machine, the method that adopts is the method for chemical process mostly, for example adopts the method for plating or clad material; Further method can be to the direct modification of the material of sewing machine component, but the cost of these ways is very large beyond doubt, and the basic way that neither address this is that, because the material that coats has its certain useful life, after the long-time use of part, the material that coats in the above must wear and tear, like this, and in order in the process of using sewing machine, to produce problems such as balling-up, broken string again again.It as a kind of patent No. 93101180.9 sewing machine component, his technical characterictic is: in order to prevent the generation of balling-up, broken string, improve durability simultaneously, at piece surfaces such as inward turning bobbin case, outward turning bobbin case, peg or spindle, bobbin case, thread take-up tension lever, presser feet, rotating shuttle frame and the rotating shuttle bar coating titanium nitride of sewing machine.The price of titanium alloy is very expensive, produces problems such as balling-up, broken string for solving in the process of using sewing machine, and uses so expensive metal to address this problem, and too waste and luxurious seems.
Summary of the invention
The utility model mainly be at existing in prior technology in using the process of sewing machine, because the backguy bore edges out-of-flatness of bobbin case, produce technical problems such as balling-up, broken string, provide a kind of rational in infrastructure, can smooth backguy bore edges, make the mould of backguy hole to the processing sewing machine shuttle putamen stay wire bore ram compression angle of advantages such as the damage of line reduces.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: mould is made up of two parts, last cylinder lower end radially is provided with a upper punch, last cylinder and upper punch are for being made into integration, again through processing, produce arc-shaped transition, following cylinder axially is provided with low punch perpendicular to it, and low punch is installed in down on the cylinder for embedding.
As preferably, described cylinder down is hollow circular cylinder; Cylinder is made and has hollowly not only been saved material, and mould strength is increased.
As preferably, described upper punch and last cylindrical junction are arc-shaped transition; This arc-shaped transition can be processed the backguy hole, makes the edge slyness in backguy hole.
As preferably, the top of described low punch and the sidewall of low punch have one to be arc-shaped transition; This arc-shaped transition can be processed the backguy hole, makes the edge slyness in backguy hole.
As preferably, described arc-shaped transition is a section of circular arc; Arc-shaped transition can be the arc-shaped transition of multiple shape, and is the most suitable with the transition of circular arc.
Therefore, the utlity model has characteristics such as simple and reasonable for structure, easy to use, it can be effectively processed the backguy hole of sewing machine bobbin case, form the punching press angle, make the corner slyness in sewing machine bobbin case backguy hole, online when passing sewing machine bobbin case backguy hole, be difficult for rubbing.
