Description
Technical field
The present invention relates to a kind of equipment of making glass punching articles, relate to a kind of corresponding method in addition.
Background technology
This kind equipment is extensive especially.It comprises a molten bath that is used for molten glass or crucible, molten bath or crucible, a homogenizing part and a so-called material feeder that is used to refine glass melt.This material feeder comprises that can reach the long groove of 10m in practice., also be equipped with one and cut except a needle-valve with a valve body and a bar and a valve seat is installed in the end of groove.Needle-valve moves back and forth under certain stroke and certain stroke height situation.Wherein, at such one back and forth in the cycle, there is a certain amount of liquation to flow out, and forms molten drop by outlet.When end cycle, molten drop disconnects by described cutting with the liquation of top.Be dropped in the pressing mold after the molten drop, and therein by the moulding of an extruding tringle.On the press bench of a turntable structure form, generally be provided with a plurality of pressing molds.
To system with regard to the weight of glass punching articles carry out continuous detecting.When deviation occurring, just the quantity of molten drop is being carried out being corrected in the quantitative process.This point particularly important.Thereby must definitely guarantee have the molten drop of exact quantity to drop onto in the die cavity.If there is too many glass molten drop to drop onto in the die cavity, will produce overdraft (Ueberpressung), seldom can compression moulding, the structure of stamping parts is also imperfect.
In order as far as possible accurately to keep the nominal amount of molten drops, people have taked many measures.For example the viscosity of the liquation in the groove is detected, because viscosity and molten drop quantitatively have very important dependency.But these measures do not cause satisfied result, because also have other influence factor, for example type of glass in action, and can change at the measuring condition of different choice position.
Keep molten drop weight to have very important significance.The weight of molten drop is on 2 to 30kg the order of magnitude.The deviation of 20g will constitute the mass defect of glass punching articles.
Summary of the invention
The object of the present invention is to provide a kind of method or device, so that the glass punching articles of manufacturing has uniform quality.
The present invention realizes by a kind of equipment of making glass punching articles about the purpose of device aspect,
-it comprises a material feeder that is used for the Locating Glass liquation, it has:
-one horizontal channel;
-one needle-valve, it has a valve rod, a valve body and a valve seat;
-one cutting unit that is connected after the valve seat;
-described needle-valve is arranged on the downstream end of groove;
-described equipment also comprises: a mold pressing platform that is connected after the material feeder;
-one device that is used for regulating valve stem and valve body stroke position;
-one device that is used to detect stamping parts weight; And
-being provided with one first regulating loop, this regulating loop changes stroke position when the weight offrating of stamping parts;
Its characteristics are:
-one device that is used to regulate glass melt temperature in the groove;
-being provided with one second regulating loop, it changes the temperature of glass melt when the stroke position offrating.
The present invention realizes that by a kind of method with glass melt manufacturing glass punching articles it has following method steps about the purpose of method aspect:
-described glass melt flows through a horizontal channel;
-in the end of groove, glass melt is derived by a needle-valve;
-described needle-valve is for localized purpose, under certain stroke and certain stroke position situation, opens and closes by certain time interval;
-when closing, the molten drop of metering disconnects with glass melt subsequently;
-molten drop is extruded moulding;
The weight of-detection stamping parts;
-when the weight offrating of stamping parts, change stroke position;
Its characteristics are:
-when the stroke position offrating, change the glass melt temperature in the groove.
The contriver has found one to solve the path thus, and its required equipment is simple in structure and cheap, and can bring perfect results.Two regulating loops are set for this reason:
The first regulating loop work is as follows: if record weight (thereby also be the weight of the molten drop simultaneously) offrating of made stamping parts just, just with this deviate as adjusting parameter, and be used to change the stroke position of needle.What this was emphasized is that itself remains unchanged stroke.Only be that geography (geodaetische-vertical) position height of needle above valve seat changes.Its result can cause the curve of stroke position to change in time.
Second regulating loop work is as follows: if after the work of first regulating loop, stroke position departs from certain value or certain scope, just changes the glass melt temperature in the groove, and till readjusting the nominal stroke position.
Description of drawings
By accompanying drawing the present invention is described in detail below, is specifically illustrated as follows in the accompanying drawing:
Fig. 1 is a diagrammatic depiction that has the material feeder of molten drop;
Fig. 2 is a diagrammatic depiction that is in the pressing mold of below;
Fig. 3 is a diagrammatic depiction with rotating disk of a plurality of pressing molds;
Fig. 4 is stroke position time history plot in a plurality of quantitative cycle of a legacy equipment (Portionierzyklen);
Fig. 5 is that stroke position is according to the present invention's time history plot in a plurality of quantitative cycles (Portionierzyklen).
Embodiment
Material feeder shown in Figure 1 comprises a horizontal channel 1, and glass melt is housed in it.From figure, except the horizontal plane 1.1 that can see glass melt, can also see a needle-valve 2 with a valve rod 2.1, a valve body 2.2 and a valve seat 2.3.After needle-valve 2, be provided with one and cut 3.A glass molten drop 4 is cut off.
Pressing mold 5 shown in Figure 2 is configured to allow molten drop 4 drop in the die cavity 5.1.The volume of die cavity 5.1 is corresponding with the nominal volume of molten drop 4.
The extruding tringle that also has that belongs to pressing mold, but also not shown in the drawings.
In Fig. 4, the bar 2.1 of needle-valve 2 and the stroke position of valve body 2.2 illustrate as ordinate zou, and the time is then as X-coordinate.Once shear by cutting 3 at X point place respectively, liquation stream is cut off thus, molten drop 4 separate with top liquation and the pressing mold 5 that drops in.In practice, one-period for example has only 1/3rd seconds.
People can see two curves from Fig. 4.Above the change curve of curve representation stroke position when glass melt is colder, below the change curve of curve representation stroke position when glass melt is warmmer.
Curve shown in Figure 5 then is illustrated in two regulating loops and works the back stroke position over time.First regulating loop deviation occurs to the weight of stamping parts and rated value reacts, and it offers a setter with this deviate as adjusting parameter, and this setter is used to change the position stroke.It is in two regulating loops the reaction faster that.
People see a sea line 6 from Fig. 5, the last rated value of its expression stroke position.This rated value should not be exceeded.When it is exceeded, just start second regulating loop.In the present embodiment, greatly about shown in the intermediate point place of chart start, see also arrow Y for this reason.The deviation of stroke position is imported in the setter as adjusting parameter, and this setter can influence the glass melt in the groove 1, and stroke position falls back to again in the rated value scope.Stroke is originally unaffected in whole regulate process.But for example change fully when operation conditions, for example because of equipment during with the glass run of complete heterogeneity, also can be adjusted.
