Description

Barrel heat treatment tool

Technical Field

The utility model relates to an operation frock especially relates to a to the barrel of equipment such as pressure vessel support, in order to prevent its frock of warping at thermal treatment in-process.

Background

At present, after the welding forming of a cylinder body of equipment such as a pressure container and the like is finished, heat treatment is needed to improve the metal performance of the cylinder body; however, in the heat treatment process, it is found that the two ends of the cylinder are easy to deform in the heat treatment process (especially the composite plate), so that a wrong variable is generated during subsequent end enclosure installation or cylinder butt joint, the end enclosure installation or butt joint precision is affected, the possibility of unqualified subsequent shooting, leakage and cracking is caused, and the subsequent safety performance of the cylinder is extremely unstable; therefore, an auxiliary tool is needed to support the cylinder during heat treatment to prevent deformation.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a barrel thermal treatment frock, it can effectually prevent that the barrel among the thermal treatment process from producing deformation.

The purpose of the utility model is realized like this:

the utility model provides a barrel thermal treatment frock, includes the inner ring of suit in the barrel, and the external diameter of inner ring is unanimous with the internal diameter of barrel, and the outer loop suit is outside the barrel, and the internal diameter of outer loop is not less than the external diameter of barrel, be connected with the polylith strap between the anchor ring of inner ring and the anchor ring of outer loop, be provided with a plurality of openings on the inner wall of outer loop, a wedge plate has all been inserted in every opening, and the bottom surface of wedge plate slides and laminates on the outer wall of barrel, the wedge surface of wedge plate and the bottom inner wall sliding contact of opening.

The utility model relates to a barrel thermal treatment frock, the thickness of wedge plate is unanimous with the width of opening.

The utility model relates to a barrel thermal treatment frock, the attachment strap is the U-shaped structure, and the one end and the interior annular ring of the attachment strap of this U-shaped structure weld mutually, and the other end welds mutually with the annular ring of outer loop.

The utility model relates to a barrel thermal treatment frock, the cover is equipped with the stainless steel ring on the outer anchor ring of inner ring, and the stainless steel ring contacts with the inner wall stainless steel layer of barrel.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an inner ring supports the barrel both ends and prevents to warp, and prevents through the stainless steel ring that the material of inner ring itself from polluting the barrel inner wall when carrying out thermal treatment to the composite sheet, and has guaranteed the stability and the simple operation nature of inner ring through attachment strap and outer loop in the support process to make the frock more have popularization and application and worth.

Detailed Description

Referring to fig. 1 to 3, the utility model relates to a barrel heat treatment tool, include the inner ring 1 of suit in barrel 101, and the external diameter of inner ring 1 is unanimous with the internal diameter of barrel 101, and outer loop 2 suit is outside barrel 101, and the internal diameter of outer loop 2 is no less than the external diameter of barrel 101, be connected with polylith strap 3 between the anchor ring of inner ring 1 and the anchor ring of outer loop 2, be provided with a plurality of openings 2.1 on the inner wall of outer loop 2, a wedge 4 has all been inserted in each opening 2.1, and the bottom surface of wedge 4 slides and closes on the outer wall of barrel 101, and the wedge of wedge 4 and the bottom inner wall sliding contact of opening 2.1;

further, the thickness of the wedge-shaped plate 4 is consistent with the width of the notch 2.1;

furthermore, the butt strap 3 is of a U-shaped structure, one end of the butt strap 3 of the U-shaped structure is welded with the annular surface of the inner ring 1, and the other end of the butt strap 3 is welded with the annular surface of the outer ring 2;

further, a stainless steel ring 1.1 is sleeved on the outer ring surface of the inner ring 1, and the stainless steel ring 1.1 is in contact with the stainless steel layer on the inner wall of the cylinder 1;

further, the installation process of whole frock does: firstly, an inner ring 1 is sleeved into a cylinder body 101, then an outer ring 2 is sleeved outside the cylinder body 101, then a wedge-shaped plate 4 is inserted into a gap 2.1 of the outer ring 2 along the outer wall of the cylinder body 101 until the whole outer ring 2 is in a tensioning state, and then two ends of a plurality of butt straps 3 are sequentially welded between the inner ring 1 and the outer ring 2.

In addition: it should be noted that the above-mentioned embodiment is only a preferred embodiment of the present patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present patent.
