DETAILED DESCRIPTION

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figures 1-7 As shown, a drawing device for fireproof cable production includes a workbench 1, with an unwinding sleeve 2 installed above the workbench 1. The operator places the cable on the outside of the unwinding sleeve 2, passes one end of the cable through the limiting ring 3 and the drawing box 14, and fixes it on the outside of the winding sleeve 7. The cable is unwound through the unwinding sleeve 2, and at the same time, the turntable 28 and the winding sleeve 7 are rotated by the motor 27 to wind the cable. The cable is then drawn through the drawing die 24 installed inside the drawing box 14.

[0025] Example 2, as Figures 1-7 As shown, a drawing device for fireproof cable production limits the cable by setting a limiting ring 3. A set of rollers 13 are controlled by a first cylinder 10 to move up and down to press the cable and straighten it. When the cable passes through the drawing die 24, the cooling oil inside the drawing box 14 is delivered to the nozzle 19 by the oil pump 18 in the prior art. The oil is sprayed onto the connection between the cable and the drawing die 24 to cool down the cable and prevent it from deforming after being heated during drawing. The cooling oil sprayed from the nozzle 19 falls into the bottom of the drawing box 14. During the falling process, the impurities in the cooling oil are filtered by the filter screen 17.

[0026] It should be noted that this utility model is a drawing device for the production of fire-resistant cables. In use, the cable is unwound through the unwinding sleeve 2, and a set of rollers 13 are moved up and down by the first cylinder 10 to clamp and straighten the cable. One end of the cable is passed through the inner wall of the drawing die 24 and fixed to the outside of the winding sleeve 7. The winding sleeve 7 is rotated by the motor 27 to wind up the cable. During the winding process, the cable is drawn through the drawing die 24. During the drawing process, the cooling oil at the bottom of the drawing box 14 is delivered to the inside of the nozzle 19 by the oil pump 18. The solution is sprayed onto the cable surface for cooling. When the worker needs to replace the drawing die 24, the die sleeve 22 is loosened, and the worker can clamp the two sides of the drawing die 24 with both hands through the groove 21. Then the die is removed. During installation, the drawing die 24 is simply inserted into the arc groove of the die base 23 and fixed by the drawing die 24. When the worker needs to replace the winding sleeve 7, the winding sleeve 7 is placed on top of the turntable 28, the fixing pin 8 is inserted into the slot 29, and then the limiting plate 30 is tightened to complete the installation and disassembly of the winding sleeve 7.
