Description
Technical field
The present invention relates to a kind of method of manufacture with the prefabricated mother metal of quartz; Concrete stretching device that relates to a kind of quartzy prefabricated rods and method; In that prefabricated mother metal is stretched as in the drawing process than the quartzy prefabricated rods of small dia with quartz, guaranteed the continuity that quartzy prefabricated mother metal is produced.
Background technology
Generally speaking, for the prefabricated mother metal of quartz is stretched as the quartzy prefabricated rods than small dia, normally utilizes horizontal flame stretching technology that the prefabricated mother metal of quartz is carried out thermoplastic and handle, with the quartzy prefabricated rods of stretched target external diameter.
Raising along with Technology; The size of quartzy prefabricated mother metal presents increasing trend; Existing horizontal flame stretching technology can't satisfy the requirement of quartzy prefabricated mother metal tensile, therefore in most of the cases uses the process furnace with induction heater or resistance heater that the prefabricated mother metal of quartz is carried out longitudinal stretching processing.At present; The longitudinal stretching method of quartzy prefabricated mother metal mainly is that two anchor clamps carry out clamping up and down to two of the prefabricated mother metal of quartz about adopting; Use process furnace that order is carried out in the effective area of hyaline-quartz prefabricated rods and soften, the mode that combines according to equal-volume principle and PID control stretches to quartzy prefabricated rods.
Above-mentioned longitudinal stretching equipment is difficult to accomplish one-off drawing when the prefabricated mother metal of quartz oversize under the height condition of limited.For example, be 8m when extending the pylon height, diameter is that 120mm and useful length are that its length will reach 9m, add the upper and lower handle of two ends welding after the quartzy prefabricated mother metal of 1m is drawn into diameter 40mm and is quartzy prefabricated rods, length overall will be above 11m.Even longitudinal stretching equipment can disposable completion stretching operation, load and unload quartzy prefabricated rods and also be unusual difficulty.
As countermeasure; Drawing process below some patent documentations (as: Chinese patent 200580002429.3) are open: side face setting external diameter big roller ditch excellent of the pinch roller that is constituted through the pair of metal material than mother metal, also draw extending the excellent clamping of the less mother metal of back diameter.This method of drawing the clamping of mother metal rod; In order to prevent that metal pinch roller from contacting with the mother metal rod; Coiling has not fixedly had weaving cotton cloth of heat-stable material formation on the surface of pinch roller, so needs often to exchange weaving cotton cloth of heat-stable material formation, has caused the cost rising; This switch-activity can influence the planeness on pinch roller surface again, makes to produce crooked mother metal rod.And this roller design is complicated, and processing and installation difficulty are big, and the probability that breaks down behind the continuous production is very high, has reduced production efficiency, has also increased production cost simultaneously.
Summary of the invention
For overcoming the deficiency of prior art, the object of the present invention is to provide the stretching device and the drawing process thereof of the prefabricated mother metal of a kind of quartz.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the present invention realizes through following technical scheme:
The stretching device of the prefabricated mother metal of a kind of quartz comprises anchor clamps, middle anchor clamps, lower clamp; The stretching pylon, caliper, process furnace; Programmable logic controller PLC, the said anchor clamps of going up are installed in said process furnace top, and said lower clamp is installed in the below of said process furnace; Said caliper connects said process furnace, and said middle anchor clamps are between said caliper and lower clamp, and a wherein end of said middle anchor clamps is provided with a cutting device.
