Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and typical embodiments.

[0023] In Fig. 1, the curved inlay of the present invention consists of four circles above the main body (1), the central axis (2), five circles above the left axis of symmetry (3), and five circles above the right axis of symmetry (3). Five circles overlap each other. From the side view, it can be seen that the axis of symmetry (4), its own axis (5), the radius (6) and the radius (8) should be the same, and the arc (7) of the arc-shaped inlay is the angle θ, and the range of the arc is based on the needs of the site Should satisfy 0°<θ<180°.

[0024] The mold used when installing the arc-shaped insert in Figure 2 is divided into two modes, one of which consists of the mold positioning hole 9 and the 5 limit holes on the left, namely the limit hole 1-1 (10), the limit hole 1- 2 (11), spacer hole 1-3 (12), spacer hole 1-4 (13), spacer hole 1-5 ...

Abstract

The invention relates to a device used to repair the surface crack of metal object and relative method. Wherein, it is characterized in that: it uses the arc embed element with same arc degree as crack surface; based on the condition of arc surface, preparing mould, marking crack line on the mould, and setting special bolts at two ends of crack line, to limit the crack; and drilling two mounting holes for positioning the mould at two ends of crack; and mounting the arc mould via said positioning holes on the arc surface; processing the arc embedded element mounting holes, and layering mounting the bolts on the crack part inside the mounting holes, to eliminate the crack; mounting special bolts at the joint between mounting hole and the crack, to be layered with the inner bolt of mounting holes; and processing the embedded element mounting hole.

Description

technical field [0001] The invention relates to the field of mechanical maintenance, in particular to methods for repairing cracks on the surface of metal objects. Background technique [0002] In daily life, some metal objects with poor toughness, such as the furnace body of a large boiler, are prone to cracks and cracks due to poor toughness, and once the cracks occur, they will extend along the trend, become longer and longer Large, and finally lead to cracks, so it is necessary to repair them in time at the initial stage of cracks. The method commonly used in the prior art is to adopt the method of welding repair, utilizes welding to carry out high-temperature heating to the metal surface around the crack, make it melt one body, eliminate crack. Because this method will cause the internal stress change after the crack, the effective time is very short, and the crack will further aggravate or regenerate the crack; Further expansion has a certain restrictive effect, but ...
