Abstract
The invention relates to a generator stator core pressing process, which is characterized in that the steps comprise fixing the lower pull head of a 1000 ton oil press in the middle position of the chassis and adjusting chassis position and level; mounting the three-cylinder synchronous hydraulic elevator on the chassis and fixing the support legs of the three-cylinder synchronous hydraulic elevator; equispaced placing the support square box and the tie plate around the three-cylinder synchronous hydraulic elevator and placing the stator base on the tie plate; entering the elevator platform to work from the inside of the three-cylinder synchronous hydraulic elevator for operator, overlaping the stator segmental lamination layer by layer and strip by strip from bottom to top and pressing by subsection, thereby completing the pressing process of the whole stator core. The invention has advantages of advanced and reasonable structure, convenient use, good stability, high efficiency.
Description
Technical field
The present invention relates to a kind of technique for press-loading generator stator iron core, can be used for that turbine generator stator core is inside and outside to press-fit, belong to the turbine generator stator core technical field.
Background technology
Stator core is the important component part of generator magnetic circuit, one of critical piece of generator.The quality of quality, performance directly has influence on the stable and generating efficiency of unit, and its manufacturing process is particularly important.
In the technology that in the 600MW turbine generator stator core, press-fits, traditional technology is that out frame stands up, the operator stands on the interior frock combined bay of support, from bottom to top repeatedly set sub-segmental punching piecewise layer by layer, segmentation compresses, frock combined bay segmentation composite assembly, thus the process that press-fits of whole stator core finished.And when the stator core segmentation compressed, the frock combined bay segmentation composite assembly mode that lasting for years is traditional was obviously inapplicable, especially for shortening the unit stator iron core pressing time, guaranteed product quality, enhanced productivity, and this technology can not adopt especially again.
It is combination wood assembling type structure that unit stator iron core pressing adopts traditional frock, its technology shortcoming is that the adjustable height of standing is by manual combined section adjustment, non-cutting time length, poor rigidity, the beat amount is big, carrying is little, not only instability but also dangerous during use, production efficiency is low, be easy to generate the collision between frock combined bay and the stator core inwall, influence product quality.
Stator core repeatedly the segmental punching of dress to press-fit the high internal diameter of back core little, the centre of stator core also has 1000 tons of hydraulic press pull bars.In narrow space, if adopt traditional unit stator iron core pressing technology, can not solve above-mentioned these problems, therefore traditional process is inapplicable.
Summary of the invention
The purpose of this invention is to provide a kind of shortening unit stator iron core pressing time, guarantee product quality, the technique for press-loading generator stator iron core of enhancing productivity.
For realizing above purpose, technical scheme of the present invention provides a kind of technique for press-loading generator stator iron core, it is characterized in that, the steps include:
The first step. fix the following pull head of 1000 tons of hydraulic presses in the centre position on chassis, adjust position, chassis and level;
Second step. three cylinder synchronous mode hydraulic elevators are installed on the chassis, fix the supporting leg of three cylinder synchronous mode hydraulic elevators;
The 3rd step. around three cylinder synchronous mode hydraulic elevators, evenly lay and support square chest and backing plate, lay out frame on the backing plate;
The 4th step. the operator enters elevator landing work from three cylinder synchronous mode hydraulic elevator inside, from bottom to top repeatedly sets sub-segmental punching piecewise layer by layer, and segmentation compresses, thereby finishes the process that press-fits of whole stator core.
Described three cylinder synchronous mode hydraulic elevators comprise elevator landing, and the elevator landing of being located on the synchronous frame is connected with oil cylinder, and oil cylinder is connected with electric liquid combined system.
The present invention adopts three cylinder synchronous mode hydraulic elevators to carry out lifting; 1500mm is raised to 9000mm from elemental height; the platform cylindrical of hydraulic elevator posts the rubber baffle, and hoistable platform can be changed according to the frame bore size, is applicable to dissimilar unit stator iron core pressings.After the disposable installation, eliminated the assembling non-cutting time of stator core former frock combined bay in press-fiting process in the use, alleviated the tense situation that the workshop crane uses, shortened press-fiting the production cycle of whole stator core, because good stability, also eliminate the collision phenomenon between the stator core inwall, guaranteed the product quality of stator core.
Advantage of the present invention is that structure is rationally advanced, economic and practical, easy to use, and good stability is safe and reliable, the efficient height.
