Abstract
The invention relates to a combined mandrel of a corrugated rubber pipe for an automobile. The combined mandrel comprises a mandrel I and a mandrel II, wherein a stud 2, a threaded hole 3, positioning pins 1 and a positioning hole 4 are connected between the mandrel I and the mandrel II, and the connecting position of the mandrel I and the mandrel II can be cut off corresponding to the corner of the corrugate rubber pipe; the stud 2 is arranged at the center of the mandrel II, and the threaded hole 3 is fixed corresponding to the mandrel II; and the two positioning pins are arranged between the mandrel I and the mandrel II, and the included angle of the two positioning pins is more than 90 degrees. Through the combined mandrel provided by the invention, after one corner is divided, the two corners of the mandrel can be changed into one corner in demolding in the use process very easily.
Description
Technical field
The present invention relates to sebific duct Mould Machining field, particularly a kind of automobile is with twining cloth sebific duct combination plug.
Background technology
Automobile is used the turbocharging sebific duct, requires the sebific duct internal diameter generally more than 70mm, and pressure is bigger, uses expressing technique to be difficult to reach the product size requirement.We can use and twine cloth technology, but this technology has limitation for shape of product, has only a bent angle like fruit product; The demoulding easily be two or more like the fruit product bent angle, and length is long; Very difficulty of the back demoulding is accomplished in sulfuration, can only produce relatively simply product of some shapes at present.We invent a kind of combined type plug mould, and it is long to solve present product, and bent angle too much is difficult to the problem of the demoulding.Through this invention, can make this technology not receive the restriction of shape of product, enlarge heavy caliber and twine cloth sebific duct production kind.
Summary of the invention
The object of the present invention is to provide a kind of cloth sebific duct combined type plug that twines; Twining the cloth sebific duct is through manual film and cloth to be wrapped on the mould plug, and through high temperature vulcanized, releasing process is produced then; Plug of the present invention is a combined type plug; Plug is divided into two parts,, solves because the difficult problem that the shape of product complicacy is difficult to the demoulding through assembling accurately and rapidly.
The present invention realizes through following technical scheme:
A kind ofly be used to twine cloth sebific duct combination plug, it is made up of plug I and plug II, is provided with double-screw bolt 2, screwed hole 3, alignment pin 1 and the locating hole 4 of connection between plug I and the plug II; The link position of plug I and plug II is that correspondence twines the position that the position of the bent angle of cloth sebific duct is broken off; Plug II center is provided with double-screw bolt 2; Fixing with plug I correspondence position screwed hole 3; Be equipped with two alignment pins between plug I and the plug II, the position angle between two alignment pins is greater than 90 degree.
Above-mentioned alignment pin exposes section 3 ~ 5mm, and locating hole 4 degree of depth are less than 10mm, and alignment pin 1 is completely fixed in locating hole.
The present invention is used to twine the preparation method of cloth sebific duct combination plug: the plug that at first is processed into two bent angles like Fig. 2; Position like Fig. 1 plug I and plug II bent angle cuts off; Tapped through hole 3 of plug II center processing; Screwed hole of the same processing in plug I center, the degree of depth is for can not penetrate the plug I.Position angle on the plug II section between processing two alignment pins 1, two alignment pin is greater than 90 degree, on the corresponding position of plug I section and plug II section alignment pin 1, processes two locating holes 4 then, and alignment pin 1 can be inserted in the locating hole fully.Process a double-screw bolt 2 with screwed hole 3 corresponding specifications then, double-screw bolt length can connect plug I and plug II.Through double-screw bolt 2, locating hole 4, alignment pin 1 plug I and plug II are linked together, accomplish a combined type plug.
The present invention is specially adapted to the above heavy caliber of 70mm, the sebific duct of two bent angles or two above bent angles.
Effect of the present invention: heavy caliber twines the cloth sebific duct, and rubber inside contains cloth, and cloth elastic force is very little; Be difficult to the demoulding above being enclosed within crooked plug; Run into the plug of two bent angles especially, through the present invention, after we cut apart one of them bent angle; In use can make plug in the demoulding, become a bent angle, be very easy to make the sebific duct after the production to separate with plug by two bent angles.

Fig. 3: plug I sketch map of the present invention;
Fig. 4: plug II sketch map of the present invention.
The specific embodiment
Below in conjunction with the marginal data specific embodiment of the present invention.
The present invention is that a kind of heavy caliber of two bent angles twines cloth sebific duct plug.
Like Fig. 1, shown in 2, a kind of cloth sebific duct plug 5 that twines of complicated shape is made up of plug I, plug II, double-screw bolt 2, screwed hole 3, two alignment pins 1, two locating holes 4.
As shown in Figure 4; The tapped through hole of a M10 of processing on the section center line of plug II; On section, process the circular hole of two
then; Degree of depth 5mm; The alignment pin 1 of ready two diameters
is inserted in the hole; Position angle between two alignment pins is greater than 90 degree, and alignment pin 1 exposes section 5mm.
As shown in Figure 3, the screwed hole of a M10 of processing on the section center line of plug I, degree of depth 15mm, requirement can not penetrate plug.Two locating holes 4 of processing on section require position of positioning hole corresponding with alignment pin then, and diameter matches with alignment pin 1, and the degree of depth requires apart from section 10mm, guarantee that alignment pin 1 exposed portions serve can be inserted in the locating hole fully.
As shown in Figure 1, two section butt joints with plug I and plug II are inserted into alignment pin 1 in the locating hole fully, use double-screw bolt 2 that plug I and plug II are combined, and accomplish a combined type plug mould.
Twined the cloth sebific duct all can be designed to be easy to processing near straight shape in the past.Along with improving constantly of customer requirement, twine the cloth sebific duct gradually by straight alteration of form in order to contain one, the perhaps different form of two bent angles.Product is the structure that contains one deck cloth in the middle of the two-layer rubber, and the elastic force of cloth is very little, and the manufacturing process that twines the cloth sebific duct is: initial sheet rubber and cloth are wrapped on the sebific duct, put into vulcanizing tank then and add sulphur; After the completion, sheet rubber has formed a tubulose, needs to break away from plug; When running into the plug of two bent angles, because the restriction of cloth elastic force, sebific duct can not break away from plug; Use the combined type plug, before the demoulding, can be with wherein one section plug disengaging earlier; Reduce by a bent angle, do not had the resistance of continuous bent angle, sebific duct just is easy to break away from remaining plug.
Structure of the present invention has no pro forma restriction, allly does any simple modification and modification according to instance of the present invention, all belongs within the technical scheme scope of the present invention.
