Abstract
A cold pressing method for making a metallic tubular tap includes cutting copper tube or stainless steel tube by desired length, blocking its one end, pouring the low-melting-point molten metal or liquid in the tube from its another end, solidifying, die pressing, heating to melting the solidified metal, pouring it out of the tube, and cleaning the inner surface of said tube.
Description
Technical field
The present invention relates to the processing method of bleeder cock, particularly relate to the cold extruding processing method of tap metal adjutage.Mainly be applicable to bathtub, bleeder cock such as the cylinder that washes the dishes.
Background technology
The tap that existing bathtub etc. is located adopts cast copper processing usually, in order to guarantee the reliability of cast copper moulding, often adds metallic elements such as zinc, tin, lead in copper product during production.But compositions such as zinc, tin, lead discharge in water pipe, and entering in the water to influence health, and therefore, people seek true yellow copper pipe, copper tube, perhaps materials processing bleeder cock such as stainless steel tube.The moulding of bleeder cock has certain aesthetic requirement, and common hot extrusion or cold extrusion difficult processing are to realize.
Summary of the invention
The invention provides materials such as a kind of application brass tube, copper tube or stainless steel tube, adopt the method for cold extrusion process water tap.The technical scheme of described cold-extruding metal pipe tap processing method is: intercepting brass tube or copper tube or stainless steel tube, an obstruction with pipe, in pipe, pour into low-melting-point metal liquid or liquid from the other end, treat that the molten metal cooled and solidified becomes workpiece after filling molten metal, workpiece is put into extrusion die, be extruded to shape, then workpiece is heated, make in the pipe and pour out after the fusing of low-melting-point metal liquid, the moulding of cleaning tube chamber.Its described being extruded to shape is at first workpiece to be put into mould, by pressure mechanism pushing workpiece, workpiece is by die cavity, and one is extruded into slotted eye, become circular hole by another pressing mechanism to being squeezed into oval-shaped workpiece pressurization enlarging again, become circular water outlet.Its described low-melting-point metal liquid is lead or tin material or liquid etc.Described pressing mechanism is a hydraulic press etc.Heating to workpiece is by heating furnace whole work-piece to be heated, and temperature is controlled at about 300-450 ℃, makes material fusings such as lead or tin just, pours out lead (tin), and the cleaning tube chamber gets shaped article.Pour in the pipe as supporter with low-melting-point metal, pipe is pushed in the die cavity of mould and pass through, shape according to die cavity becomes ellipse, again of water outlet is squeezed into circle again from ellipse, after establishing the shape moulding of die cavity according to meter fully, metal support is poured out by heating, not only shape is attractive in appearance, and the tap that obtains is that brass, red copper or stainless steel material are made, and is harmless.
Description of drawings

Fig. 2 is that cold-extruding metal pipe tap A-A of the present invention is to schematic diagram.
The specific embodiment
The present invention relates to the method for cold extrusion processing metal pipe tap, take needed length such as brass tube or copper tube or stainless steel tube, one to pipe 2 is stopped up, in pipe, pour into low-melting-point metal liquid material or liquid such as other oil, water such as lead or tin from the other end, treat after filling that molten metal (lead or tin) cooled and solidified becomes workpiece.Again workpiece is put into extrusion die, be extruded to shape,, make and pour out after low-melting-point metal liquid dissolves in the pipe, the moulding of cleaning tube chamber then to the workpiece heating.For the method that is extruded to shape be: at first workpiece is put into mould cavity (the die cavity shape is the same with finished product tap shape), can be by the pressure mechanism pushing workpiece of equipment such as hydraulic press, because of die cavity is to become ellipse from cylindrical the differentiation gradually, so workpiece is by behind the die cavity, one produces distortion, be squeezed into oval endoporus 3, but the delivery port of tap can not elliptical aperture, therefore workpiece is pressurizeed from of oval pore by another pressing mechanism (oil cylinder) again, again enlarging becomes circular hole, becomes circular water outlet 4.Be two extruding at this moment, and to begin be the single head pushing.Open mould after the extrusion modling of two, take out shaping workpiece, again workpiece heating is made low-melting-point metal fusings such as lead in the tap or tin, pour out molten metal liquid, the purge tube inwall, obtain product as shown in Figure 1 and Figure 2, the water inlet 1 and the water outlet 4 of tap pipe 2 all are circular holes, and the stage casing is oval endoporus 3.The method of described workpiece heating is by heating furnace whole work-piece to be heated, and temperature is controlled at about 300-450 ℃, makes the fusing of lead or tin, pours out lead or tin melt, and the cleaning tube chamber gets shaped article.
Claims (5)
1, the processing method of cold-extruding metal pipe tap, it is characterized in that intercepting brass tube or copper tube or stainless steel tube, an obstruction with pipe, in pipe, pour into low-melting molten metal or liquid from the other end, treat after filling that the molten metal cooled and solidified becomes workpiece, puts into extrusion die with workpiece, be extruded to shape, then, make in the pipe and pour out after the fusing of low-melting-point metal liquid, the moulding of cleaning tube chamber the workpiece heating.
2, the processing method of cold-extruding metal pipe tap as claimed in claim 1, it is characterized in that described being extruded to shape is at first workpiece to be put into mould, by pressure mechanism pushing workpiece, workpiece passes through die cavity, one is extruded into slotted eye, by another pressing mechanism a workpiece pressurization enlarging that is squeezed into elliptical aperture is become circular hole again, become circular water outlet.
3, the processing method of cold-extruding metal pipe tap as claimed in claim 1 is characterized in that described low-melting-point metal liquid is lead or tin material.
