Large synchronous multitubular long-stroke tube expander device

Abstract

The invention discloses a large synchronous multitubular long-stroke tube expander device which comprises a rack structure and a tube fixing clamp, wherein the tube fixing clamp is fixed on the rack structure; the rack structure comprises a main support and a main beam which is fixed on the main support; a pushing and expanding guide track and a pushing and expanding toothed bar are arranged on the upper surface of the main beam; the tube fixing clamp is fixed at one end of the main beam; at least one expanding rod bracket is arranged on the pushing and expanding guide track between the tube fixing clamp and an expanding rod installation plate; expanding rods are arranged side by side; one end of each expanding rod is fixed on the expanding rod installation plate; the expanding rods are supported and limited by the expanding rod bracket; and the other end of each expanding rod penetrates through the tube fixing clamp. The large synchronous multitubular long-stroke tube expander device has the advantages as follows: a device which can adjust the position and expand each row of finned tubes automatically is provided; the device is convenient to use and high in working reliability and provided with an automatic slipping detection mechanism; and moreover, the device can be suitable for two types of tube-pitch production, and the application range for production can be expanded by changing the fixation of the expanding rods.

Description

technical field [0001] The invention relates to the field of tube expansion equipment. Background technique [0002] With the acceleration of the global industrialization process, the requirements for resource conservation and environmental protection are getting higher and higher. Steam power, thermal power and nuclear power have more and more urgent requirements on how to save energy, how to reduce costs and fully protect the environment. Faced with such a requirement, a super-large heat exchange system was produced and installed in the hyperbolic tower of the current power plant, allowing the sub-pressure steam to dissipate heat through the heat exchanger pipes, fully recovering the sub-pressure steam for power generation, and turning the steam into hot water. Recycling, thereby saving energy consumption. [0003] The production of large-scale heat exchange products requires that the diameter of the heat sink aluminum tube or copper tube is 25mm, and the length of a sin...

AI Technical Summary

Problems solved by technology

Due to the asynchronous operation of the expansion rods, the four expansion rods have a sequence. The first to expand must wait for the unexpanded ones, causing the friction wheel to slip on the expansion rods, the expansion rods wear, the pressure wheel wears and the pressure wheel bearing damage

Frequent machine maintenance and low efficiency result in product quality. Lubricating inside the tube is done by manual oiling. One-time tube expansion is completed by manually moving the machine for alignment. Tube removal is completely done by manual observation. All these increase the intensity of manual labor and damage the health of workers.
