Abstract

The utility model relates to a W-Mo wire drawing device. The utility model comprises a wire unreeling wheel, a wire coiling wheel and a wire drawing die. The utility model is characterized in that the utility model also comprises a transformer, a voltage regulator, an electrode and an insulated block; the electrode is installed at one end near the wire unreeling wheel; a spring attachment is arranged above the electrode; one end of two output ends the transformer is connected with the electrode, and the other output end is connected with the input end of the wire drawing die; the output end of the voltage regulator is connected with the input end of the transformer. In the utility model, the W-Mo wire is used as a section of conducting wire in a circuit, and the W-Mo wire is directly heated; therefore, the heat loss is little, and the energy saving effect is noticeable. The utility model can be widely used in various W-Mo wire drawing industries.

Description

Tungsten silk wire-drawing frame

The utility model relates to a kind of metal-working plant, particularly about a kind of equipment that draws the tungsten silk.

Draw the tungsten silk that uses in the bulb at present both at home and abroad, all adopt the naked light heating to finish basically, the heating of tungsten silk, mould also will heat.And the method for heating mainly contains two kinds, and a kind of is the coal gas heating, and auxiliary equipment such as air compressor machine, gas station need be set; Another kind is the oil gas heating, needs gasoline air compressor machine, steam etc.Because these two kinds of heatings all are to adopt the heating of naked light heating source, thermal loss is big, and consumes energy is many, and air pollution is serious, workman's high-temperature operation, and working environment is very poor.

At the problems referred to above, the purpose of this utility model is that the heater to wire drawing machine improves, and provides a kind of equipment simple, and energy consumes little, the tungsten silk wire-drawing frame of good work environment.

For achieving the above object, the utility model is taked following design: a kind of tungsten silk wire-drawing frame, it comprises actinobacillus wheel, take-up pulley and wire drawing die, described wire drawing die is installed near described take-up pulley one end, it is characterized in that: it also comprises transformer, pressure regulator, electrode and collets, described electrode is installed near described actinobacillus wheel one end, a spring attachment is set on described electrode, two output one ends of described transformer are connected on the described electrode, the other end is connected the input of described wire drawing die, the output of described pressure regulator is connected with the input of described transformer, in the installing hole of described actinobacillus wheel and take-up pulley, put into described collets respectively, the tungsten filament winding is crossed described actinobacillus wheel, pass described electrode and wire drawing die, be looped around on the described take-up pulley.

The utility model is owing to take above design, and it has the following advantages: 1, owing to adopt devices such as transformer, pressure regulator, electrode, with the tungsten silk as the section lead in the circuit, directly heat, thermal loss is little, and the energy utilization is abundant, and energy-saving effect is very remarkable.For example: originally MR-500 wire drawing machine power consumption is 3 kilowatts, uses the utility model power consumption instead and only is 60 watts.2, need not heat owing to wire drawing die, and the tungsten silk is to enter wire drawing die the hottest time marquis that therefore the tungsten mercerising of pulling out is bright, does not have burr, good product quality.3, owing to removed the naked light heating source, there are not air pollution and hyperthermia radiation, workman's good operational environment.The utility model is simple in structure, and is easy to operate, and the product processed cost is low, and quality is good.It can be widely used in the various drawing tungsten silk industries.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is the utility model structural representation

Fig. 2 is that retractable line wheel is installed the collets schematic diagram

As shown in Figure 1, the utility model is the improvement of carrying out on the basis of original wire drawing machine heater, and the parts relevant with improvement part comprise actinobacillus wheel 1, take-up pulley 2 and wire drawing die 3.In the installing hole of actinobacillus wheel 1 and take-up pulley 2, fix collets 4 (as shown in Figure 2) respectively, so that insulate with complete machine, and actinobacillus wheel 1 and take-up pulley 2 be installed in together with collets 4 on the installation site of original wire-drawing frame, at this moment may need certainly the installing hole of retractable line wheel 2,1 is enlarged a bit.As shown in Figure 1, wire drawing die 3 is installed near take-up pulley 2 one ends, electrode 5 is installed near actinobacillus wheel 1 one ends.Electrode 5 is two electrode blocks in parallel, two electrode blocks is separated certain distance install, and at two a spring attachment 6 is set above the electrode block.The input of a transformer 7 is connected a pressure regulator 8, two output one ends of transformer 7 are connected on the electrode 5, the other end is connected the input of wire drawing die 3.At last tungsten silk 9 is walked around actinobacillus wheel 1, pass the gap between electrode 5 and the spring attachment 6, enter wire drawing die 3, after tungsten silk 9 is pulled out from wire drawing die 3, be wrapped on the take-up pulley 2.

In the above-described embodiments, the installation of electrode and electrode can also be taked other form.

The time marquis of operation connects power supply, heating-up temperature regulation voltage as required with the input of pressure regulator.At this moment tungsten silk and the circuit turn-on between electrode and the wire drawing die, in the process of wire, the tungsten silk is heated gradually from electrode one end, and temperature is the highest when arriving the input of wire drawing die.Under the rotation of take-up pulley, the tungsten silk is drawn into necessary diameter in wire drawing die.
