Embodiment 1

[0048] Such as Figure 1 to Figure 3 As shown, a V-groove weld forming tool is used for V-groove welding, which includes three main components: a pressing device 100, a connecting device 200 and a flexible pad 300, through which three components Complete the welding seam forming work on the V-groove. Among them, the flexible gasket 300 adopts a heat-resistant fiber structure, and in order to be able to adapt to the back of the weld seam of the V-shaped groove and fit and seal it, the shape generally adopts a rectangular structure. The flexible gasket 300 of this embodiment adopts aluminum silicate fiber rope. The specific structure and working principle of the pressing device 100 and the connecting device 200 will be described in detail below.

[0049] The pressing device 100 includes a pressing plate 110 and a pressing assembly 120 . Wherein, the shape of the pressing plate 110 can be adaptively selected according to the actual situation, and it is a rectangular structure ...

Embodiment 2

[0068] A method for preparing the flexible pad 300 in Embodiment 1, the specific process is as follows:

[0069] 1. Use stamping equipment such as a punching machine to stamp the metal sheet, and form a row of sharp corner structures on the edges of both sides of the metal sheet, forming a shape such as Figure 8 structure shown.

[0070] 2. Then bend both sides of the metal sheet, and bend it into a Figure 9 structure as shown, and sharpen the corners with an angle grinder.

[0071] Three, such as Figure 10As shown, the bent metal sheet is placed on the rectangular flexible pad 300, and the bending parts on both sides are pressed down, so that the sharp corners are inserted into the flexible pad 300 from both sides of the flexible pad 300 to form a metal strip 310, the final formed flexible liner 300 as Figure 11 shown.

[0072] 4. Finally, spot-weld the fixing rings at the two ends of the metal strip to form a complete flexible gasket 300 assembly that can be quickly...

Abstract

The invention discloses a V-shaped groove weld joint forming tool and a preparation method of a gasket of the V-shaped groove weld joint forming tool, and belongs to the field of weld joint forming. The V-shaped groove weld joint forming tool comprises a compressing device, a connecting device and a flexible gasket. The compressing device comprises a pressing plate and a compressing assembly. Eachof the two sides of the pressing plate is provided with a pressing block; penetrating screw grooves are formed in the pressing blocks in the length direction of the pressing plate; the compressing assembly is used for fixing the pressing plate to a workpiece to be welded; the flexible gasket is of a rectangular strip structure; and the surface of the upper end of the flexible gasket is coated with a metal strip; the connecting device comprises a pair of fixing rings and a pair of adjusting bolts; the fixing rings are arranged at the two ends of the flexible liner respectively; the front endsof the adjusting bolts are of conical structures; the adjusting bolts penetrate through screw grooves and stretch into the fixing rings; the flexible gasket can be rapidly and accurately fixed in theV-shaped groove through the adjusting bolts; and operation and use are extremely convenient. The preparation method is used for preparing the flexible gasket in the tool; and the prepared flexible gasket effectively improves the welding efficiency of the V-shaped groove.

Description

technical field [0001] The invention belongs to the field of welding seam forming technology, and more specifically relates to a V-groove welding seam forming tool and a preparation method thereof. Background technique [0002] In the prior art, the ceramic liner forming method and the water-cooled copper backing plate forming method are mainly used to solve the problem of weld formation. However, in actual use, these two weld formation methods have many shortcomings. Among them, the ceramic material of the ceramic liner forming method is easily damaged, and the recycling rate is not high. At the same time, the ceramic liner is a rigid liner, which requires high assembly of welded joints, and is difficult to apply to the welding process of the circular seam of the cylinder middle. The water-cooled copper backing plate forming method has high manufacturing costs and poor adaptability to the state of the weld. At the same time, it is also difficult to apply to rigid liner cur...
