Description

Technical Field

[0001] The present invention belongs to the technical field of metal welding equipment, and particularly relates to a tooling for welding long welds of titanium-steel composite plates. Background Art

[0002] Titanium-steel composite plates are materials formed by laminating titanium plates and steel plates, with the corrosion resistance of titanium, the high strength of alloy steel, and excellent comprehensive properties such as good thermal conductivity. In industries such as chemical engineering and pressure vessels, titanium-steel composite plates have become indispensable structural materials.

[0003] Currently, titanium plates and steel plates are welded over a large area and laminated by explosive welding. Since the overall area of the titanium plate is relatively small compared to the steel plate, several titanium plates need to be assembled and welded before lamination. During the assembly welding, due to the relatively thin thickness of the titanium plate, it is more prone to deformation compared to the steel plate, and there may be partial bending or partial warping at the welding edge of the titanium plate. In this way, when two titanium plates are assembled, there will be a height difference at the welding edges of the two titanium plates. If welding is directly carried out, the welding area will be significantly uneven, resulting in local stress concentration in the welding area, which will cause insufficient strength in the welding area of the welded titanium plate, thereby reducing the overall fatigue resistance and crack resistance of the titanium-steel composite plate. Moreover, microcracks are likely to form in the stress concentration area, and these cracks may expand during subsequent processing or use, leading to the failure of the welded titanium plate.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0019] like Figure 1-Figure 6 As shown, a tool for welding a long weld of a titanium-steel composite plate comprises a base plate 1, a guide rail 2 mounted on the base plate 1, a welding machine 3 movably mounted on the guide rail 2, and two clamping frames 4 mounted on the base plate 1, two titanium plates 11 are held under the two clamping frames 4, and the long weld between the two titanium plates 11 is located between the two clamping frames 4; the tool also comprises: A sealing cover 5, on which a connecting rod 51 is disposed, the other end of which is fixed on a movable platform of the welding machine 3, and a welding head of the welding machine 3 is located in the sealing cover 5; The correction roller 6 and the sealing cover 5 are installed with a telescopic part 53 on one side, and a shaped plate 54 is provided at the output end of the telescopic part 53. The correction roller 6 is rotatably installed in the shaped plate 54. The correction roller 6 is tightly against the top surfaces of the two titanium plates 11, and the correction roller 6 is located at the front end of the moving direction of the sealing cover 5.

[0020] Furthermore, a plurality of telescopic parts 41 are provided on the pressing frame 4, the output end of the telescopic part 41 extends into the pressing frame 4 and is installed with a shaped plate 42, a pressure roller 43 is rotatably installed in the shaped plate 42, the pressure roller 43 is tightly pressed against the top surface of the titanium plate 11, and a driving part 44 is installed at one end of the pressure roller 43.

[0021] Furthermore, guide plates 52 are provided on both sides of the sealing cover 5 , and guide grooves 45 are provided on the pressing frame 4 , and the guide plates 52 are sleeved in the guide grooves 45 .

[0022] In one case of this embodiment, the telescopic member 1 41 and the telescopic member 2 53 can both be cylinders or other components that can be telescopically driven; the driving member 44 can be a motor or a component that can drive the pressure roller 43 to rotate.

[0023] In actual application of this embodiment, the long weld between the two titanium plates 11 is continuously welded by the mobile welding machine 3. Before welding, the telescopic member 2 53 is extended to make the correction roller 6 rest on the two titanium plates 11. During welding, the mobile welding machine 3 drives the sealing cover 5 to move through the connecting rod 51, so that the correction roller 6 rolls. The rolling of the correction roller 6 will flatten the bent part and the raised part on the titanium plate 11. Moreover, the correction roller 6 rolls at the moving front end of the welding machine 3. In this way, when the welding machine 3 is welding, the welding edges on the two titanium plates 11 remain flush, so that there will be no obvious unevenness in the welding area, and the local stress concentration in the welding area is effectively avoided, so as to ensure that the strength of the titanium plate after welding is sufficient, and effectively avoid reducing the overall fatigue strength and crack resistance of the titanium-steel composite plate after the welded titanium plate is composited with the steel plate, and avoid cracks in the welding area of ​​the welded titanium plate, thereby avoiding failure of the welded titanium plate. When the sealing cover 5 moves, the sealing cover 5 is guided by the guide plate 52 so that the sealing cover 5 moves in a horizontal direction to prevent the sealing cover 5 from shaking up and down, thereby ensuring that the correction roller 6 always rolls the two titanium plates 11, thereby ensuring that the welding edges on the two titanium plates 11 remain flush to avoid problems after welding; A heat sink 55 is installed on the sealing cover 5. The heat sink 55 can be a heat sink or a cooling water system. The heat sink 55 can effectively reduce the high temperature generated during the welding process to prevent the welding overheating from causing adverse effects on the welding quality and welding equipment. During welding, the pressure roller 43 is moved downward by extending a number of telescopic parts 41, thereby pressing the two titanium plates 11. This can effectively prevent the titanium plate 11 from shifting when being rolled by the correction roller 6, and prevent the two titanium plates 11 from being misaligned, thereby preventing the two sides of the welded titanium plate 11 from being misaligned, resulting in dimensional deviation, and avoiding cutting of the welded titanium plate 11 to cause waste of materials.

[0024] like Figure 4-Figure 8 As shown, a spacer ring 61 is arranged on the periphery of the correction roller 6, and the width of the spacer ring 61 is equal to the width of the weld between the two titanium plates 11. An auxiliary ring 62 is arranged on the periphery of the spacer ring 61, and the width of the auxiliary ring 62 is smaller than the width of the weld. A guide groove 14 is opened from the top to the bottom of the bottom plate 1, and part of the auxiliary ring 62 is located in the guide groove 14. The bottom of the guide groove 14 is in an inclined state, and the inclination direction is toward the moving direction of the sealing cover 5.

[0025] It should be noted that during welding, there may be deviations in the weld width between the two titanium plates 11, which can easily lead to uneven stress distribution inside the weld and easily form stress concentration areas in the welding area. These stress concentration points may become the starting points for crack initiation and expansion, thereby reducing the strength and toughness of the welding area; at the same time, it may also cause welding deformation, which may cause the welded titanium plates 11 to have dimensional deviations or poor fit during use; based on this problem, a spacer ring 61 is set to adjust the width of the weld.

[0026] In actual application of this embodiment, the spacer ring 61 is located between the two titanium plates 11, and the width of the spacer ring 61 is equal to the width of the weld between the two titanium plates 11. During welding, the correction roller 6 drives the spacer ring 61 to roll, and at the same time, the pressure roller 43 is rotated by the driving member 44. The rotation directions of the pressure rollers 43 on both sides are opposite, so that the titanium plates 11 on both sides move toward each other. When the two titanium plates 11 move toward each other, they are blocked by the spacer ring 61, so that the width of the weld between the two titanium plates 11 is always consistent, thereby ensuring the strength of the welding area of ​​the welded titanium plates 11, effectively avoiding the occurrence of stress concentration areas in the welding area, effectively avoiding reducing the strength and toughness of the welding area, and at the same time effectively avoiding deformation of the welding area, and avoiding problems such as dimensional deviation or poor fitting of the welded titanium plates 11 during use.

[0027] Furthermore, a plurality of movable grooves 621 are provided on both sides of the auxiliary ring 62, and a plurality of cleaning components 7, degreasing components 8 and wiping components 9 are respectively installed in the plurality of movable grooves 621. The cleaning components 7, degreasing components 8 and wiping components 9 form a group of components, and the plurality of groups of components are in a ring array. The cleaning components 7, degreasing components 8 and wiping components 9 in each group of components are connected together. When the correction roller 6 rolls, the cleaning component 7 first contacts the weld surface, then the degreasing component 8 contacts the weld surface, and finally the wiping component 9 contacts the weld surface.

[0028] Furthermore, the cleaning component 7 includes a movable plate 1 71, which is movably installed in the movable groove 621, and a wire brush 711 is arranged on the surface of the movable plate 1 71; the degreasing component 8 includes a movable plate 2 81, which is movably installed in the movable groove 621, and a degreasing block 811 is arranged on the surface of the movable plate 2 81, and a layer of cotton cloth soaked in ethanol is arranged on the surface of the degreasing block 811; the wiping component 9 includes a movable plate 3 91, which is movably installed in the movable groove 621, and a wiping block 911 is arranged on the surface of the movable plate 3 91, and a layer of dry cloth is arranged on the surface of the wiping block 911; a plurality of elastic members 10 are connected between the movable plate 1 71, the movable plate 2 81 and the movable plate 3 91 and the movable groove 621.

[0029] It should be noted that during welding, the groove on the weld of the titanium plate 11 is easily invaded by hydrogen, oxygen, nitrogen, etc. These gases will react with titanium at high temperature to form brittle compounds, reducing the mechanical properties of the weld. Based on this problem, a corresponding structure is set on the auxiliary ring 62 for cleaning.

[0030] In one case of this embodiment, the elastic member 10 may be a spring or other elastically expandable member. The elastic member 10 enables the movable plate 1 71 , the movable plate 2 81 and the movable plate 3 91 to always have a tendency to move out of the movable groove 621 .

[0031] In actual application of this embodiment, the correction roller 6 drives the auxiliary ring 62 to roll when rolling. When the auxiliary ring 62 rolls, the wire brush 711 first contacts the groove on the weld to clean the surface of the weld groove and remove impurities such as oil, scale, etc. on the surface of the weld groove. The cleaned impurities enter the guide groove 14 and fall to the bottom of the guide groove 14. After being cleaned by the wire brush 711, the degreasing block 811 contacts the groove surface. The degreasing block 811 is wrapped with a layer of cotton cloth soaked in ethanol, wherein the ethanol is sulfur-free ethanol. The degreasing block 811 degreases the groove surface, and then the wiping block 911 contacts the groove surface to wipe the groove surface clean, so that the groove surface reveals a metallic luster. The groove surface is cleaned by the wire brush 711, the degreasing block 811 and the wiping block 911, so that harmful gases such as hydrogen, oxygen, and nitrogen at the weld groove can be effectively cleaned, thereby improving the welding quality and strength of the welding area.

[0032] like Figure 5 and Fig. 9 As shown, an air pipe 12 is installed through one side of the sealing cover 5, and the air pipe 12 is connected to an external air supply unit, and the external air supply unit supplies inert gas to the air pipe 12. An air guide pipe 13 is installed on one side of the inner cavity of the sealing cover 5 close to the correction roller 6.

[0033] Further, the airway 13 comprises: An inclined plate 131, both ends of which are fixed on the inner wall of the sealing cover 5; The second inclined plate 132 is symmetrically arranged on one side of the inclined plate 131; A main conduit 133 is provided between the two inclined plates 132, and the main conduit 133 extends into the guide groove 14. The thickness of the main conduit 133 is less than the thickness of the guide groove 14; An air blowing pipe 134, one side of the main pipe 133 is connected with the air blowing pipe 134, and the air blowing pipe 134 faces the bottom of the auxiliary ring 62; The cooling pipe 135 is connected to the other side of the main conduit 133 . The cooling pipe 135 is L-shaped, with its end facing the inside of the sealing cover 5 , and the downward projection of the welding machine 3 faces the air outlet of the cooling pipe 135 .

[0034] In one case of this embodiment, the inert gas may be argon gas, and the purity of argon gas is higher than 99.99%.

[0035] In actual application of this embodiment, argon gas is input into the sealing cover 5 through the gas pipe 12. Argon gas is used as a protective gas to form an inert atmosphere to prevent the weld and the titanium plate 11 from reacting with oxygen, nitrogen, etc. in the air, thereby avoiding adverse effects such as oxidation and nitridation, thereby improving the welding quality; at the same time, the injection of argon gas can cool the titanium plate 11 and the weld, which helps to quickly cool the welding area and reduce the size of the heat-affected zone, thereby reducing the possibility of deformation of the titanium plate 11 and the weld area; in addition, argon gas can remove impurities, oxides and other harmful substances generated during welding from the weld, maintain the purity of the welding area, and improve the quality and strength of the weld; The argon gas is in the sealing cover 5, which can be guided to be evenly distributed around the welding area, thereby improving the protection effect, and at the same time can reduce the turbulence of the argon gas in the sealing cover 5, making the gas pressure and flow more stable, which is conducive to improving the welding quality; After the argon gas enters the sealing cover 5, the excess argon gas will enter the main duct 133 through the guidance of the inclined plate 131 and the two inclined plates 132. A part of the argon gas is blown out from the blowing pipe 134. The blown argon gas can blow the impurities cleaned by the wire brush 711 off the wire brush 711, thereby preventing the impurities from adhering to the wire brush 711 and preventing the impurities from adhering to the weld groove, thereby avoiding affecting the welding quality. At the same time, the argon gas flows along the guide groove 14, so that the cleaned impurities are discharged along the guide groove 14; another part of the argon gas is blown out from the cooling pipe 135, and the blown argon gas contacts the bottom of the welding area, thereby further reducing the possibility of deformation of the titanium plate 11 and the weld area.

[0036] like Figure 5 As shown, a monitoring device 15 is installed in the sealing cover 5.

[0037] In actual application of this embodiment, the monitoring device 15 can be a camera or other device for transmitting images. The monitoring device 15 is connected to an external display to monitor the welding situation through the external display, so that when welding errors occur, they can be discovered in time and the welding can be terminated, effectively avoiding welding errors.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
