Assembling tool for flap type end enclosure

Abstract

The invention discloses an assembling tool for a flap type end enclosure, and belongs to positioning and adjusting tools. The problem of difficult assembling of medium-large flap type end enclosures in the pressure vessel manufacturing field is mainly solved. The assembling tool comprises positioning plates 1, portal frames 2 and taper pins 3. When the tool is used for mounting, the positioning plates 1 are welded and fixed to the two sides of an opposite opening of flaps 8, the portal frames are symmetrically inserted into the positioning plates 1, the taper pins 3 are knocked in and fixed, thus, the adjacent flaps 8 are connected and fixed, and tapered iron 4 and tapered iron 5 are inserted for adjusting in order to further ensure the opposite opening alignment tolerance and gap requirement. Through the tool, all the flaps 8 can be rapidly fixed, overall assembling is achieved, meanwhile, the alignment tolerance and gaps are easy to adjust, the advantages of the simple structure, easy manufacture and rapid mounting and dismounting are achieved, the assembling quality and efficiency can be improved, and the assembling tool can be used as a standard part to be further popularized to assembling of other large split parts such as barrels and cones.

Description

technical field [0001] The invention relates to a pairing tool, in particular to a pairing tool for a large melon flap type head in the field of pressure vessel manufacturing. Background technique [0002] The development trend of large-scale chemical equipment makes the diameter and wall thickness of the main parts of the head more and more large. Due to the limitation of forming equipment and molds, this kind of head usually cannot be integrally formed, and can only be formed by mold pieces. The first method is to form a piece of melon petals first, and then the whole melon petals are assembled and welded to form the whole head. Although it is a melon petal, its weight and shape are still huge. At the same time, due to the inevitable size and shape deviations in the melon petals during processing and forming, the overall assembly of the melon petals is very arduous and difficult, especially when adjusting the gap. It is time-consuming and labor-intensive, often unable to ...

Problems solved by technology

Although it is a melon petal, its weight and shape are still huge. At the same time, due to the inevitable size and shape deviations in the melon petals during processing and forming, the overall assembly of the melon petals is very arduous and difficult, especially when adjusting the gap. It is time-consuming and labor-intensive, often unable to meet the requirements, and eventually leads to a vicious cycle of various welding defects and repairs. Therefore, how to quickly fix the melon petals as a whole, and at the same time effectively adjust the pairing gap and misalignment between the melon petals The requirement to ensure the overall size, shape and welding quality of the parts has become a difficult problem in the assembly of such large melon-shaped heads.
