Abstract
The invention discloses a stocking falling barrel of a stocking knitter and a production method thereof. The stocking falling barrel of the stocking knitter comprises a round-tube-shaped body, wherein a tube wall is provided with a plurality of small holes; the body is an integrally formed round tube; and the small holes are formed by etching. The production method for the stocking falling barrel of the stocking knitter comprises the following steps of: cutting a metal round tube of appropriate specifications into sections with required length; cleaning the tube wall, and coating a protective layer according to the design requirement; etching the tube wall uncovered by the protective layer by using acidic liquid to form the small holes; and removing the acidic liquid and the protective layer. The stocking falling barrel has a completely smooth tube wall and high verticality and hardness; in addition, only a few steps such as cutting, coating, etching, cleaning and the like are quickly performed in the production process, and mass repeated production can be realized, so production efficiency is greatly improved.
Description
Technical field
The invention belongs to the Knitting Machinery field, particularly relate to the stocking leg that falls that footwear machine is used, and the production method of this stocking leg that falls.
Background technology
The stocking leg that falls is the vitals of footwear machine, after the socks braiding is finished, need utilize negative pressure, makes socks leave footwear machine from the stocking leg that falls.For realizing this purpose of design, the stocking leg that falls need be the pipe shape, has some apertures on the circumferential wall so that socks are pasting tube wall slides.In the prior art, fall the stocking leg with sheet metal coil around after be welded, earlier on sheet metal, stamp out some apertures by design, again it is wound as the pipe shape, weld then, polish, obtain smooth tube wall.The shortcoming of this stocking leg that falls is, can leave the formed regulus of machined, crator etc. on the tube wall, will hook the silk of socks and its hook is broken during work, therefore must obtain smooth tube wall by polishing; The polishing operation quite takes time and effort, and be difficult to accomplish smooth fully, the influence quality of the stocking leg that falls thus, in addition since be with sheet metal coil around forming, so perpendicularity and hardness are not good.
Summary of the invention
It is simple to the purpose of this invention is to provide a kind of production, and tube wall is smooth, perpendicularity and the high stocking leg that falls of hardness.
Another object of the present invention provides the production method of this stocking leg that falls.
For realizing first goal of the invention, the technical scheme of being taked is such: the stocking leg that falls of footwear machine, comprise a pipe shape body, and tube wall is provided with some apertures, it is characterized in that: described body is the pipe of global formation; Described aperture is that etching gets.
For realizing second goal of the invention, the technical scheme of being taked is such: the production method of the stocking leg that falls of footwear machine, comprise the steps: to choose the suitable metal circular tube of specification, and it is cut into required length; Clean tube wall, armor coated by designing requirement; Dissolve the not tube wall of protected seam covering with acidic liquid, form aperture; Remove acidic liquid and protective layer.
The present invention adopts integrated metal circular tube to make the main body of the stocking leg, processing such as does not need to weld again, also just not have to weld the crator welding slag that brings etc.; Adopt the way of chemical etching to produce aperture, formed hole wall progressively enlarges with molecular level, can not produce shape sudden change physically in the forming process, so there are not shape defects such as regulus, burr, the tube wall of the stocking leg of falling is perfectly smooth, and the circularity of the stocking leg that therefore falls improves.Owing to be one-body molded, do not have external force that stack shell is exerted pressure and make it distortion, so its perpendicularity be good simultaneously, hardness also significantly improves than prior art.On the other hand, in several steps such as production process of the present invention only need be blocked, coating, etching, cleaning, these steps are all than faster, and duplication of production in force, so production efficiency has also improved greatly.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is the fall schematic diagram of the stocking leg of the present invention.
The specific embodiment
Referring to Fig. 1.The copper pipe that the stocking leg 1 that falls is formed in one, aperture 2 spread all over to fall half area of the stocking leg 1 vertical stack shell, and second half of the stocking leg 1 that falls be not for the copper pipe of aperture 2.After socks fall into the stocking leg 1, the effect of being under pressure, socks are close to narrow meshed one and are breakked away, and can not produce upset and accumulation in the stocking leg 1 that falls.
The production method of the stocking leg that falls of footwear machine comprises the steps: to choose cross-sectional diameter and is 5 centimetres copper pipe, and it is cut into required length; Clean the outer tube wall of copper pipe, the film that will have an aperture by designing requirement is attached on the outer wall of copper pipe and forms protective layer; Tube wall with the etching solution dissolving is not covered by film forms aperture; Obtain the stocking leg 1 after removing protective layer and etching solution.
Certainly, also can other materials make the stocking leg that falls of the present invention,, all fall within protection scope of the present invention as long as its production method is identical with the present invention with product.
Claims (2)
