[0026] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The present application embodiment discloses a flexible bonding pressurization tool and method, such as Figure 1 As shown, a flexible bonding and pressurizing tool comprises a flat belt 1, a first connecting member 2, a self-locking mechanism 3, a second connecting member 4 and an elastic rope 5.

[0028] The two ends of the flat belt 1 are respectively connected to the first connecting member 2 and the second connecting member 4, the self-locking mechanism 3 is connected to the first connecting member 2, the elastic rope 5 is connected to the second connecting member 4, and the other end of the elastic rope 5 can be fixed by the self-locking mechanism 3. Specifically, the end of the flat belt 1 passes through the first connecting member 2 and the second connecting member 4 and folds back to a connecting portion, and the connecting portion and the flat belt 1 are sewn by braided thread; one end of the elastic rope 5 passes through the second connecting member 4 and folds back to a fixed section, and the fixed section and the elastic rope 5 are sewn by braided thread.

[0029] The length of the flat belt 1 is 3 / 4 of the circumference of the bonding position of the irregular pipe.

[0030] like Figure 2 In Figures a, b and c, the self-locking mechanism 3 includes a fixed end 3-1 and two wedge blocks 3-2. The fixed end 3-1 has a V-shaped groove inside and an opening on one side for convenient placement of the elastic rope 5. The contact positions of the two wedge blocks 3-2 have semicircular grooves. The semicircular grooves of the two wedge blocks 3-2 relatively form a circular groove, and the surface of the semicircular groove has serrations to increase the extrusion friction.

[0031] The elastic rope 5 is placed in the circular grooves of the two wedge blocks 3-2, and then the combined wedge block 3-2 is placed in the fixed end 3-1 of the self-locking mechanism 3. The tension of the elastic rope 5 makes the wedge block 3-2 contact and lock with the V-shaped groove of the fixed end 3-1, thereby achieving the purpose of structural stability.

[0032] The flat belt 1 is a soft rope belt, and the material of the flat belt 1 is Kevlar, which has no elasticity itself.

[0033] The elastic rope 5 is made of elastic material and has a plurality of annular marking lines along its length. In a naturally collapsed state, the distances between adjacent annular marking lines are equal. When in use, the number of tightened marking lines is judged to determine whether the pressure meets the bonding requirements.

[0034] A pressurizing method for a flexible bonding pressurizing tool comprises the following steps:

[0035] 1. Calculate the length of flat belt 1 in the flexible bonding and pressurizing tooling according to the circumference of the bonding position of the irregular pipe fitting, and assemble the bonding and pressurizing tooling;

[0036] 2. After the gluing work on the irregular pipe surface is completed, place the flat belt 1 around the surface of the pipe bonding object;

[0037] 3. Assemble the elastic rope 5 with the two wedge blocks 3-2 in the self-locking mechanism 3;

[0038] 4. Place the assembled wedge block 3-2 into the fixed end 3-1 of the self-locking mechanism 3;

[0039] 5. Pull the free end of the elastic rope 5 to tighten the elastic rope 5, observe the annular marking line in the elastic rope 5, and when the tightening marking line is reached, press the wedge block 3-2 into the fixed end 3-1;

[0040] 6. The tension of the elastic rope 5 and the self-locking structure of the self-locking mechanism 3 are used to achieve a stable connection of the tooling, thereby achieving the purpose of circumferential pressure on the bonded parts.
