Abstract
The utility model discloses a dieless drawing device for copper-phosphorus filaments. The dieless drawing device comprises a sealed box body with a heat insulation layer and a pair of step pulleys which are arranged in the box body and are driven by a motor, wherein the speed ratio of the step pulleys is 1.05:1; the bottom of the box body below the step pulleys is provided with an electric heating disc, and the side wall of the box body is provided with a wire guiding hole; and the box body corresponding to the wire guiding hole is provided with an winding reel externally. When the dieless drawing device is used, thicker copper-phosphorus welding wires are sleeved on the pair of step pulleys, the end parts of the copper-phosphorus welding wires are lead out from the wire guiding hole and are fixed on the winding reel; and heat-conducting oil is poured into the box body, the electric heating disc is electrified to heat heat-conducting oil, the motor is started to drive the step pulleys to rotate, so that the isothermal drawing of the copper-phosphorus brazing filler metal filaments is realized, and the problems that difficulty in dimensional precision and higher filament breakage rate during processing when the copper-phosphorus brazing filler metal filaments are processed conventionally are solved.
Description
Technical field
The utility model relates to the drawing welding wire device, especially relates to a kind of copper phosphorus filament dieless drawing device.
Background technology
Copper-phosphorus brazing alloy is the most a kind of hard solder of current application, mainly is used for metals such as brazed copper and copper alloy, silver, molybdenum, and is huge in refrigeration, motor, electric power, automobile and other industries consumption.The processing method of copper-phosphorus brazing alloy can be divided into direct casting, ingot casting hot extrusion and hot pull, powder by atomization, amorphous state preparation etc.Because the plasticity extreme difference of copper-phosphorus brazing alloy under the cold working condition, people adopt the hot-working means that the copper-phosphorus brazing alloy welding wire is carried out drawing usually.Though had certain methods and equipment can realize copper-phosphorus brazing alloy is carried out hot pull at present, when carrying out copper-phosphorus brazing alloy filament (Φ 1.0mm and following) drawing, the dimensional accuracy of welding wire is difficult to guarantee, adding the man-hour wire broken rate sharply increases.
Summary of the invention
The purpose of the utility model is to utilize the superelastic characteristics of copper-phosphorus brazing alloy and a kind of copper phosphorus filament dieless drawing device of providing.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described copper phosphorus of the utility model filament dieless drawing device, it comprises the enclosed housing that has heat-insulation layer, and it is interior by motor-driven a pair of cone pulley to be arranged on said casing, the speed ratio between the said cone pulley is 1.05:1; The bottom half that is positioned at the cone pulley below is provided with electric heat-generating disc, on the sidewall of said casing, offers and draws a hole, is outside equipped with take-up block with the said corresponding casing in a hole that draws.
On said cabinet exterior, be fixed with supporting frame, said take-up block is positioned on the support frame as described above body.
The advantage of the utility model has been to realize the isothermal drawing of copper-phosphorus brazing alloy filament (Φ 1.0mm and following), and dimensional accuracy is difficult to guarantee when having solved conventional worked copper phosphorus brazing alloy filament, processing wire broken rate problem of higher.
During use, the copper phosphorus welding wire that will omit thick (Φ 1.2mm) is enclosed within on a pair of cone pulley successively, and the end is fixed on the take-up block after draw in a hole from drawing; Conduction oil is injected in the casing, do not have cone pulley and copper phosphorus welding wire, with electric heating plate energising heating conduction oil; When treating that the conduction oil temperature rises to 220 ℃～300 ℃; Starter motor drives cone pulley and slowly rotates, because copper-phosphorus brazing alloy generation superplastic deformation; Can obtain the copper phosphorus filament of Φ 0.93mm, the finished product filament is wrapped on the take-up block through drawing a hole.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the described copper phosphorus of the utility model filament dieless drawing device, it comprises the enclosed housing 2 that has pearlite insulating layer 3, and the speed ratio that is arranged between a pair of cone pulley 4, two cone pulleys 4 that driven by motor 1 in the casing 2 is 1.05:1; The bottom half that is positioned at cone pulley 4 belows is provided with electric heat-generating disc 5, on the sidewall of casing 2, offers to draw a hole 6, and draws a hole 6 corresponding casings 2 and is outside equipped with take-up block 7.For making its compact conformation, on cabinet exterior, be fixed with supporting frame, take-up block 7 is positioned on the supporting frame.
During work, the copper phosphorus welding wire of Φ 1.2mm is mounted on the cone pulley 4 successively, the end is drawn from draw a hole 6 and is fixed on the take-up block 7.Conduction oil is injected in the enclosed housing 2, do not have cone pulley 4 and cover copper phosphorus welding wire above that, with electric heat-generating disc 5 energisings; Treat that the conduction oil temperature rises 220 ℃～300 ℃ the time; Starter motor 1 drives cone pulley 4 and slowly rotates, because copper-phosphorus brazing alloy generation superplastic deformation; Can obtain the copper phosphorus filament of Φ 0.93mm, the finished product filament is wrapped on the take-up block 7 outside the casing 2 through drawing a hole 6.
