[0025] Example

[0026] like Figure 1As shown, the utility model is a pre-cooling device for adding a cooling water ring of a wire tube, comprising a pipeline water cooling device 1 and a pipeline air cooling device 2. The pipeline water cooling device 1 uses water circulation to cool the tube blank 11 by heat conduction, so as to achieve the effect of rapid cooling and shaping of the tube blank 11. By adding the pipeline air cooling device 2 at the rear end of the pipeline water cooling device 1, the pipeline air cooling device 2 performs non-contact cooling treatment on the high-temperature tube blank 11, and increases the hardness of the tube by surface pre-cooling to solve the problem of precipitation of the threading tube in the sizing sleeve; the present invention first lowers the outer surface temperature of the high-temperature and unshaped tube blank 11 just extruded from the die for initial shaping, so that the tube blank 11 has a certain hardness when it enters the pipeline water cooling device 1 for the shaping and cooling process, which can effectively avoid the damage of the inner wall of the sizing sleeve of the inner cooling water ring 4 to the shaping process of the tube blank 11.

[0027] The pipeline water cooling device 1 includes an outer cooling water ring 3 and an inner cooling water ring 4. The outer cooling water ring 3 is buckled on the inner cooling water ring 4 to form a cooling water sleeve ring cavity 5. A water inlet 6 is provided on the outer cooling water ring 3, and a water outlet 7 is provided on the inner cooling water ring 4. The circulating water pipe inlet is connected from the water inlet 6, and the outlet pipe is connected to the water outlet 7 to discharge the circulating water after absorbing heat.

[0028] The rear end face of the pipeline water cooling device 1 is connected to a pipeline air cooling device 2, and the pipeline air cooling device 2 includes an outer cooling air ring 8 and an inner cooling air ring 9. The outer cooling air ring 8 and the inner cooling air ring 9 are both connected to the rear end face of the outer cooling water ring 3. The outer cooling air ring 8 is buckled on the inner cooling air ring 9 to form a cooling air sleeve cavity 10. An air cooling ring cavity 12 is reserved between the inner cooling air ring 9 and the tube blank 11. An air inlet 13 is provided on the outer cooling air ring 8. A plurality of air outlet holes 14 are evenly distributed around the inner ring surface of the inner cooling air ring 9. The air inlet pipe is connected to the air inlet 13. Cold air enters the air cooling ring cavity 12 through the air inlet 13, and then is evenly sprayed on the tube blank 11 through the air outlet holes 14 on the inner ring surface of the inner cooling air ring 9. From the rear end process of the inner cooling air ring 9, the tube blank 11 first passes through the pipeline air cooling device 2 to reduce the outer surface temperature of the tube blank 11 for initial shaping, and then passes through the pipeline water cooling device 1 to achieve shaping.

[0029] Before extrusion production, the outer cooling water ring 3 and the inner cooling water ring 4 are assembled through threaded connection, and then installed at the front end of the cooling water tank; the outer cooling air ring 8 and the inner cooling air ring 9 are assembled through threaded connection, and then installed on the end face of the cooling water jacket through threaded connection; the cooling water pipe and air pipe are connected, and the installation is completed.

[0030] During normal production, the tube billet is extruded from the extrusion die, passes through the pre-cooling connection sleeve, and the air enters the air pipe. The air is blown through the hole screen to act on the outer surface of the tube billet, and the outer surface temperature of the tube billet is reduced, the toughness of the tube billet is reduced, and the strength is increased, thereby achieving the pre-cooling effect; the tube billet is transferred through the pre-cooling and enters the cooling water ring, and the cooling water enters the flow channel between the cooling water ring and the cooling water jacket for heat alternation to achieve water cooling; the vacuum cooling water tank provides negative pressure vacuum, and the tube billet is sizing by negative pressure vacuum water cooling.

[0031] The cross section of the outer cooling water ring 3 is an L-shaped structure, and the cross section of the inner cooling water ring 4 is also an L-shaped structure, and the two L-shaped structures are connected to each other to form a cooling water jacket ring cavity 5. This structure is convenient for installation and connection, and also convenient for subsequent maintenance.

[0032] The tube blank introduction port 15 at the rear end of the inner cooling water ring 4 is rounded. The rounded corner treatment can reduce the damage of the inner wall of the sizing sleeve of the inner cooling water ring 4 to the shaping process of the tube blank 11. The tube blank outlet 16 at the front end of the inner cooling water ring 4 is provided with a water-cooling transition ring cavity 17. The water-cooling transition ring cavity 17 is provided so that after the tube blank 11 is led out from the pipeline water cooling device 1, it can effectively reduce the influence of temperature on the structural shape and strength of the tube blank 11 during the transition in the water-cooling transition ring cavity 17. The outer ring surface of the inner cooling water ring 4 is partially provided with a plurality of heat dissipation ring grooves 18. The heat dissipation ring grooves 18 are provided to facilitate heat exchange between the inner cooling water ring 4 and the cooling water, thereby improving the cooling efficiency of the tube blank 11.

[0033] The utility model discloses a precooling device for adding a cooling water ring of a wire pipe. A pipeline air cooling device 2 is added to the rear end of a pipeline water cooling device 1. The pipeline air cooling device 2 performs non-contact cooling treatment on a high-temperature pipe blank 11, and increases the hardness of the pipe material by surface precooling to solve the problem of precipitation of the threading pipe material in the sizing sleeve. When precipitation is adhered and accumulated on the inner wall of the sizing sleeve, the toughness of the pipe blank is reduced, and the precipitation can be better brought out, and the phenomenon of sinking or breaking of the pipe blank between the extrusion mold and the cooling water tank can be better avoided. The structure of the pipeline water cooling device 1 is reasonably arranged, and the damage of the inner wall of the sizing sleeve of the inner cooling water ring 4 to the shaping process of the pipe blank 11 is effectively reduced, and the production quality of the plastic pipe is effectively improved.
