Problems solved by technology

For this reason, it is necessary to solve the problem of dynamic heat and cold isolation between the two different functional sections of the orientation cone. The above-mentioned patent does not solve this problem; and the cooling water ring of the above-mentioned patent is fixed on the inlet pipe port of the cooling water tank, and cannot move forward and backward. , the process adjustment of the hot and cold sections of the two different functional areas of the orientation cone cannot be carried out; in addition, the thermal retraction force at the end of the biaxial orientation is particularly large, and the straight section of the cone should not be too long, otherwise it will cause huge damage to the traction. Burden, it is better to use the immersion type to improve cooling efficiency and cooling uniformity, but the circulating water in the water chamber in the patent CN 202357431U is to directly cool the pipe with pressurized water, which requires the orientation of the cone part in the biaxial orientation of the PVC pipe. A dynamic thermal isolation is not possible

Abstract

The invention belongs to the technical field of PVC pipe cooling equipment, and particularly relates to an internal shaping cooling device for a PVC biaxial oriented pipe. The internal shaping coolingdevice comprises a water ring, wherein a water inlet connector is arranged on the outer circumference of the water ring; water outlet holes are formed in the inner wall of the water ring, a sponge sleeve is arranged on one side of the inner wall of the water ring, and a front ring pressing plate and a rear ring pressing plate are arranged at the two ends of the water ring correspondingly; and supporting assemblies and a connecting plate are arranged outside the water ring, a guide column is arranged between the supporting assemblies, the connecting plate is provided with a guide column sleeve, the water ring can freely move along the guide column through the guide column sleeve arranged on the connecting plate, and the connecting plate is connected with the supporting assemblies through an arranged lead screw. According to the internal shaping cooling device for the PVC biaxial oriented pipe, the lead screw enables the water ring to move to finely adjust the pipe diameter, the front ring pressing plate and the rear ring pressing plate clamp an elastic sealing ring to limit the elastic freedom degree of the elastic sealing ring, and the heating and cooling boundary of an orientation part can be accurately adjusted according to needs, so that the production process is guaranteed; and the structure is simple, cost is low, and dismounting and mounting are convenient, so that application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of PVC pipe cooling equipment, and in particular relates to an internal shaping cooling device for PVC biaxially oriented pipes. Background technique [0002] As a new type of pipe, PVC biaxially oriented pipe has the advantages of good impact resistance and strong pressure bearing capacity. Performance allows it to be applied to higher pressures and harsher environments. It is a subject that people have been pursuing but not easy to achieve while reducing product cost and improving its performance. [0003] In recent years, a large number of domestic plasticizing enterprises have entered the research and production of PVC biaxially oriented pipes. This invention is a "one-step" PVC biaxially oriented pipe cooling and sizing device designed for the special processing process of PVC biaxially oriented pipes. [0004] All plastic pipes have cooling and shaping of the product. Now the common shaping methods a...
