Description
Technical Field
The utility model relates to the technical field of welding, in particular to a welding auxiliary device.
Background
A heat exchanger is a device widely used in chemical, oil refining, power, food, light industry, pharmaceutical and many other industrial sectors. In chemical enterprises, the investment of the heat exchanger accounts for about 10-20% of the total investment. Due to the worldwide energy crisis, the demand of industrial production for heat exchangers is rapidly increasing to reduce energy consumption, and higher requirements are put on the production efficiency and production cost of heat exchanger manufacturers.
In the prior art, when a large-scale heat exchanger is produced, a shell cylinder of the heat exchanger is manufactured in multiple sections and then is spliced together by welding. In the welding process, the barrel is subjected to the action of an uneven temperature field and a large residual stress exists in a heat affected zone, so that the barrel can deform. Once the barrel is deformed, the correction is very complicated, and the time is wasted, thereby increasing the production cost. There is a need for a device that prevents the barrel from deforming during the welding process.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a welding tool for a water cooler shell of a reduced-roof supercharger, which can keep the shell of a heat exchanger from deforming in the welding process and has a simple structure.
The utility model is realized by the following technical scheme:
a welding tool for a water cooler shell of a top reduction supercharger comprises a circular ring, wherein the outer diameter of the circular ring is slightly smaller than the inner diameter of the shell of a heat exchanger to be welded, a gap is formed in the circular ring, and a cushion block is padded in the gap; and two sides of the notch are respectively provided with a convex block extending towards the inner part of the circular ring.
Further: and square bar blocks are welded at the notches.
Further: the circular ring is provided with a plurality of through holes.
Further: and a plurality of rib plates are symmetrically arranged on the side surface of the circular ring.
Further: the circular ring is formed by welding a plurality of sections of same segmented rings.
Further: the circular ring is welded with a support column, and the axis of the support column is coincided with the diameter of the circular ring.
Compared with the prior art, the utility model has the following advantages:
firstly, embedding the circular ring into the inner diameter of the heat exchanger shell, and then clamping the circular ring between the two convex blocks by using a jack, so that the gap can be opened by using the jack, and the outer diameter of the circular ring is expanded to fully support the inner diameter of the heat exchanger shell; and filling a plurality of cushion blocks into the gap, and detaching the jack. At the moment, the inner diameter of the heat exchanger shell is fully supported by the circular ring, so that the heat exchanger shell is prevented from being heated and deformed.
And secondly, the through holes on the circular ring are convenient for hoisting the circular ring with large size and heavy weight.
And thirdly, the rib plate can ensure that the ring is more stably installed on the inner diameter of the shell of the heat exchanger.
Fourthly, the circular ring adopts a multi-section welding mode, and the manufacturing difficulty and the manufacturing cost of the large-size circular ring are reduced.
And fifthly, the supporting columns support the circular ring, so that the circular ring is not easy to deform, and the effect that the circular ring supports the shell of the heat exchanger and is not deformed is improved.
