Abstract
The invention relates to a rubber tube core production process which is characterized in that the position, close to the hook end, of a tube core is additionally provided with a positioning block, a tube core bending tool is designed according to the shape and the size of the tube core, and the tube core is formed in a one-shot mode after being heated. The defect that tube openings in two ends become oval can be avoided through the rubber tube core production process, and the two ends portions are needless to be cut as long as the length of a tube blank is correct before vulcanization.
Description
Technical field
The present invention relates to sebific duct tube core production field, especially a kind of sebific duct tube core production technology.
Background technology
Traditional tube core two ends generally lengthen the long 25-30mm of pipe, and reason is that pipe packs into after tube core, and the mouth of pipe can be out of shape, and after sulfuration, just the Partial Resection of distortion, the method waste robber materials, increases and cut together crushed element operation, waste of manpower financial resources again; Die material aspect: common tube core is to adopt ordinary carbon steel, gets rusty easily, the frictional force while increasing the demoulding, and pipe internal layer can be pulled, and affects product quality.
In addition, the method that tradition is manufactured tube core is to calculate each curved angle and each corner between curved according to drawing, heats tube core curved each bent angle separately while manufacturing tube core, if adjacent bent angle is not same plane, need to mix up the angle between it.This method efficiency of manufacturing tube core is very low, foozle large (because each bent angle will be adjusted its corner, curved more, error is just larger, and serious is defective), lost labor, material and time.
Summary of the invention
In view of this, the object of this invention is to provide a kind of sebific duct tube core production technology.
The present invention adopts following scheme to realize: a kind of sebific duct tube core production technology, is characterized in that: at tube core, near hook end, increase a positioning block, and according to die shape and size design one pipe bending mandrel frock, after heating tube core, once curve type.
In an embodiment of the present invention, described locating piece has the groove of 30 °.
In an embodiment of the present invention, described tube core adopts stainless steel SUS316.
In an embodiment of the present invention, described tube core adopts centreless grinding to be worked into needed size after curving type, avoids the situation that in use tube core gets rusty, and can guarantee layer tissue and presentation quality in sebific duct.
The present invention can avoid the two ends mouth of pipe to occur oval shortcoming, as long as pipe length is correct before sulfuration, without cutting both ends.
Accompanying drawing explanation
Fig. 1 is that the present invention is with the tube core structure schematic diagram of locating piece.
Fig. 2 is pipe bending mandrel tool structure schematic diagram of the present invention.
The specific embodiment
For making object of the present invention, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the present invention be described in further detail.
The invention provides a kind of sebific duct tube core production technology, as depicted in figs. 1 and 2, at tube core 1, near hook end 3, increase a positioning block 2, and according to die shape and size design one pipe bending mandrel frock 4, after heating tube core, once curve type.
Locating piece effect has two: location when 1) pipe is installed, 2) because locating piece has the groove of 30 °, as long as be in place during installation, the elliptical shape that groove produces when just pipe is installed is corrected into circle.The method can avoid the two ends mouth of pipe to occur oval shortcoming, as long as pipe length is correct before sulfuration, without cutting both ends.Die material aspect: the present invention adopts stainless steel SUS316, adopts centreless grinding to be worked into needed size, avoids the situation that in use tube core gets rusty, and can guarantee layer tissue and presentation quality in sebific duct.
The present invention can design pipe bending mandrel frock according to 2D/3D product figure, with above product, is example, after heating tube core, can once curve type, has the top die tool that radian is corresponding to press down in curved process.This manufacture method efficiency is high, and error is little, and two ends mouth of pipe relative position size can guarantee, guarantee to install, and than traditional manufacture method, be that efficiency improves more than 80%, manufacturing qualification rate is 100%.
Above-listed preferred embodiment; the object, technical solutions and advantages of the present invention are further described; institute is understood that; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
