Tube Fixing Fixtures for Tube Expansion Equipment

Abstract

The invention discloses a tube fixing clamp of tube expansion equipment. The tube fixing clamp comprises multiple locking mechanisms which are distributed side by side and suitable for multi-tube-pitch adjustment, wherein each locking mechanism is formed by a locking clamping jaw and a locking sleeve; the locking clamping jaws are fixed on clamp mounting bases which are fixed on a machine head mounting bottom plate; the locking sleeves are fixed on a synchronous pushing block; the synchronous pushing block is connected with air cylinder rods of locking air cylinders fixed on supporting columns of the machine head mounting bottom plate. The tube fixing clamp has the advantages that the tube fixing clamp can be used for fixing multiple tubes simultaneously and is matched with multiple distributed expansion rods to realize a synchronous tube expansion function; the clamp can detect whether a tube falls in time, the phenomenon that the expansion rods push equipment backwards is avoided, and the work stability and the reliability of the equipment are improved.

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...

Problems solved by technology

In addition, at present, whether the pipes fall off is mostly manually observed. If the production is large-scale, and multiple pipes are expanded at the same time, the effect will inevitably be observed. In addition, manual observations are inevitable, and when the pipes fall off, even if the power is turned off quickly, There will also be a delay, causing damage to equipment and finished products, and this damage is sometimes even irreversible!
