Problems solved by technology

[0002] The nozzle shrinking device is the head part of the pipe shrinking machine, which is the key actuator to complete the nozzle shrinking. The nozzle shrinking device is to uniformly reduce the outer diameter of one end of the steel pipe to a certain length, and is used for the connection between multiple steel pipes. Or other forms of connection, because the sizes of steel pipes used in different situations are not the same, which requires different nozzle constriction devices to correspond to them, so this type of nozzle constriction device has a single function and poor adaptability, and increases equipment costs. At the same time, the external structure of the nozzle shrinking device in the prior art is a ring-shaped whole, and the interior is the executive part of the shrinking nozzle, which leads to the fact that the slag skin and other wastes that fall off the steel pipe head cannot fall out in

Embodiment 1

[0023] Embodiment one, see Figure 1-6 , a hollowed-out nozzle shrinking device, the device includes a fixed seat, a drive body installed inside the fixed seat and a shrinking mold;

[0024] The fixed seat includes a cylindrical main body, a guide flange and a sealing end plate respectively fixed at both ends of the main body, and the guide flange is fixed on the outer surface of the main body by bolts uniformly distributed along its edge and along the circumference. On the end face, the bolts horizontally penetrate the guide flange and are screwed on the outer end face of the main body. A sleeve is set on each bolt and the two ends of the sleeve are respectively supported on the end face of the guide flange and the main body. The guide flange is fixed on the main body through the bolt sleeve, and a hollow area is formed between them. When the tube is shrunk, the slag and other sheds can fall out through the gap between the mold seat monomers and the hollow area. To prevent a...

Abstract

The invention relates to a hollowed-out pipe orifice shrinking device. The device comprises a fixing seat, a driving body and a pipe shrinking mold, wherein the driving body and the pipe shrinking mold are arranged inside the fixing seat, the fixing seat comprises a cylindrical main body, a guide flange plate and a sealing end plate which are fixed at the two ends of the main body correspondingly,the driving body comprises a front-section cylindrical driving head and a rear-section cylindrical sliding tail, the pipe shrinking mold comprises N-numbered sector-shaped single pipe shrinking bodies with the inner arc surfaces and the outer arc surfaces, each single pipe shrinking body comprises a single mold base body and a single mold body used for shrinking pipes, every two single pipe shrinking bodies are supported by springs, the guide flange plate is fixed on the main body by the bolts sleeving sleeves, so that a circle of hollowed-out area is formed between the guide flange plate andthe main body, so that falling objects such as slag skin can be conveniently removed during the pipe shrinking process, and are prevented from being accumulated in the device, and different single mold bodies can be selected according to the pipe diameter.
