Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a general-purpose overlay welding forming device. Background Technology

[0002] Currently, materials with low melting points and high fluidity, such as Babbitt metal, tin, copper, and aluminum, are often subject to edge leakage and poor forming conditions when undergoing additive welding and weld repair, such as Babbitt metal torpedo welding. Due to the fluidity of the material during welding, edge leakage and poor forming conditions often occur. Usually, forming molds are set up to fix the edge shape in order to form the weld metal layer and protect the weld edge from leakage.

[0003] Most existing molding dies adopt a fixed rigid structure, that is, a fixed rigid mold is made by welding steel plates according to the shape of the Towa Babbitt alloy weld overlay layer. Because the mold is a welded structure, the anti-leakage effect is good. However, the rigid structure mold can only be used one-to-one with the Towa size. When the Towa size is different, a mold needs to be made for each Towa size, which increases the cost of Towa welding and seriously reduces the welding efficiency.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Summary of the Invention

Detailed Implementation

[0018] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings. Example 1

[0019] like Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional structural view of the lower forming template; Figure 2 This is a three-dimensional structural view of the upper forming template.

[0020] This embodiment mainly focuses on the localized overlay welding of materials such as Babbitt metal, tin, copper, and aluminum onto a plate surface.

[0021] The universal overlay welding forming device of this utility model includes a lower forming template 1 and / or an upper forming template 2. Both the lower forming template 1 and the upper forming template 2 are vertically arranged rectangular plates. The lower forming template 1 and the upper forming template 2 are made of magnetically absorbable materials such as iron and steel. A first magnetic block 3 is embedded in one end face of the lower forming template 1 and the upper forming template 2 in the extending direction. Adjacent lower forming templates 1 or upper forming templates 2 are magnetically connected and vertically arranged through the first magnetic block 3, thereby forming an adjustable rectangular frame structure on the workpiece to be overlaid for overlay welding of rectangular cross-section overlay layers.

[0022] Preferably, a second magnetic block 4 is embedded in the bottom end face of the lower forming template 1. The lower forming template 1 is magnetically fixed to the workpiece to be welded by the second magnetic block 4, thereby ensuring that the rectangular frame structure is stable on the workpiece to be welded, and at the same time, the position can be adjusted adaptively.

[0023] Both ends of the upper forming template 2 are embedded with the first magnetic block 3. Adjacent upper forming templates 2 are magnetically connected to the same plane through the first magnetic block 3 to form a forming limiting plate. The ends of the forming limiting plate are perpendicularly connected to the adjacent forming limiting plates through the first magnetic block 3, thereby forming the rectangular frame structure. The size of the rectangular frame structure can be adjusted by adjusting the number of upper forming templates 2 on the forming limiting plate.

[0024] Preferably, the upper end face of the lower forming template 1 is provided with a first slide rail groove 5 extending in a straight line, and the upper and lower end faces of the upper forming template 2 are respectively provided with a second slide rail groove 6 and a guide rail 7 extending in a straight line. The lower forming template 1 and the upper forming template 2 that are adjacent to each other are connected by the first slide rail groove 5 and the guide rail 7, and the upper forming template 2 that are adjacent to each other are connected by the second slide rail groove 6 and the guide rail 7. Through the structural arrangement of the first slide rail groove 5, the second slide rail groove 6 and the guide rail 7, the height of the rectangular frame structure can be adjusted, thereby facilitating the setting of the limit layer of different heights.

[0025] The cross-sections of the first slide rail groove 5, the second slide rail groove 6, and the guide rail 7 are all set as T-shaped structures with matching dimensions, thereby ensuring a stable connection between adjacent lower forming templates 1 and upper forming templates 2, as well as between adjacent upper forming templates 2.

[0026] This invention forms an adjustable rectangular frame structure by setting up a magnetically attachable lower forming template 1 and an upper forming template 2. This restricts the flow of material during welding, making it easier to weld materials with low melting points and high fluidity, such as Babbitt metal, tin, copper, and aluminum. At the same time, the magnetic structure ensures a tight fit at the connection points, reducing material leakage caused by gaps. Example 2

[0027] like Figure 3 As shown, Figure 3 This is a structural view of Embodiment 2 of the general-purpose overlay forming device; in this embodiment, the main focus is on overlay forming of materials such as Babbitt alloy, tin, copper, and aluminum on the top of a tile on a single steel base 10.

[0028] The general-purpose surfacing forming device of this utility model further includes a forming template shoulder clamp 8, which is fixedly set on the operating platform 9. The workpiece to be surfacing is clamped and fixed on the operating platform 9 by the forming template shoulder clamp 8. The forming template shoulder clamp 8, the lower forming template 1 and the upper forming template 2 are arranged sequentially from bottom to top. The lower forming template 1 and the upper forming template 2 are both arranged around the outside of the workpiece to be surfacing.

[0029] The operating platform 9 has multiple mounting slots 11 extending in a straight line in parallel. The mounting slots 11 are T-shaped slots. The forming template shoulder pad clamp 8 is provided with mounting holes 12. The bolt heads of the mounting bolts 13 are engaged in the mounting slots 11 and can move linearly along the mounting slots 11. The mounting bolts 13 pass through the mounting holes 12 and are threadedly connected to the mounting nuts 14, thereby realizing the installation and fixation of the forming template shoulder pad clamp 8 on the operating platform 9. By adjusting the position of the forming template shoulder pad clamp 8 on the operating platform 9, the workpiece to be welded can be clamped and fixed.

[0030] Generally, the forming template shoulder clamp 8 is horizontally provided with a mounting plate 15 of magnetically adsorbable materials such as iron and steel, which is used to fix and place the lower forming template 1. Example 3

[0031] like Figure 4 and Figure 5 As shown, Figure 4 This is a structural view of Embodiment 3 of the general-purpose overlay welding forming device; Figure 5 This is an internal structural view of Embodiment 3 of the general-purpose overlay welding forming device. In this embodiment, the main focus is on simultaneously overlaying and forming the top of the brackets made of materials such as Babbitt alloy, tin, copper, and aluminum on multiple straight-lined steel bases 10. In this embodiment, the brackets are straight-edge Babbitt alloy brackets, that is, the rectangular cross-sectional dimensions of the steel bases 10 are consistent from top to bottom.

[0032] The universal overlay welding forming device of this utility model also includes a partition 16, which is made of ceramic fiber material. The partition 16 is disposed between adjacent steel bases 10. The top height of the partition 16 is slightly lower than the height of the overlay layer, and the top of the partition 16 is provided with a side strip 17. The side strip 17 is made of welding wire material for overlay welding, thereby separating the overlay layer areas on each steel base 10. Multiple support tiles can be overlaid at the same time, while leaving gaps between adjacent support tiles to facilitate later cutting and separation. At the same time, it can also ensure that the forming template shoulder clamp 8 clamps and fixes multiple steel bases 10.

[0033] Preferably, the universal overlay welding forming device of this utility model further includes an auxiliary support 18. Multiple lower forming templates 1 are magnetically connected on the same plane by the first magnetic block 3 to form a fixed limiting plate for contacting and fixing on the side of the steel base 10. By setting different numbers of lower forming templates 1 on the fixed limiting plate, the needs of overlay welding multiple steel bases 10 can be met. The auxiliary support 18 is fixed on the operating platform 9, and the top of the auxiliary support 18 is in contact with the bottom end of the middle part of the fixed limiting plate to ensure the stability of the long fixed limiting plate structure formed by multiple lower forming templates 1. Example 4

[0034] In this embodiment, the main focus is on simultaneously welding the top of the brackets made of materials such as Babbitt alloy, tin, copper, and aluminum onto multiple straight steel bases 10. In this embodiment, the brackets are folded Babbitt alloy brackets, that is, the steel base 10 has a folded corner in the middle. The rectangular cross-sectional dimension above the folded corner is smaller than the rectangular cross-sectional dimension below the folded corner, resulting in a larger gap at the top between adjacent steel bases 10.

[0035] In this embodiment, the partition 16 is arranged around the corner of the steel base 10 to avoid the formation of gaps between adjacent steel bases 10 and between the steel base 10 and the upper forming template 2, which would cause material to accumulate in the gaps. The edge strip 17 adopts a rectangular frame structure and is set on the top of the partition 16 around the steel base 10. Example 5

[0036] The specific molding method of this utility model includes the following steps: S1, with the surface of the tile to be welded facing upwards, the base 10 of the tile is placed on the operating platform 9; S2, clamp the forming template shoulder pad clamp 8 on both sides of the tile, and fix the bottom of the forming template shoulder pad clamp 8 on the operating platform 9; S3, Install the fixed limiting plate; Specifically, the top of each of the lower forming templates 1 on the fixed limiting plate is attracted to the top of the forming template shoulder clamp 8 by the second magnetic block 4, and the surface of the fixed limiting plate is in close contact with one side of the base 10; adjacent fixed limiting plates are vertically fixed by the first magnetic block 3 at the end, thereby surrounding the four fixed limiting plates outside the base 10, and the fixed limiting plates are in close contact with the four sides of the base 10 respectively.

[0037] S4, Install the forming limiting plate and perform overlay welding within the welding area enclosed by the forming limiting plate.

[0038] Specifically, the guide rail 7 at the bottom of the upper forming template 2 is inserted into the first slide rail groove 5 at the top of the fixed limiting plate. Adjacent upper forming templates 2 on the same forming limiting plate are connected by the first magnetic block 3. Adjacent forming limiting plates are vertically fixed by the first magnetic block 3 at their ends, thereby surrounding the four forming limiting plates at the corresponding weld overlay positions. The guide rail 7 of the upper forming limiting plate is inserted into the second slide rail groove 6 of the lower adjacent forming limiting plate, thereby setting the height of the forming limiting plate.

[0039] Preferably, when multiple straight-edge brackets are welded simultaneously, they can be placed side by side, with a 3mm-4mm partition plate 16 between each bracket. A Babbitt metal welding wire or Babbitt metal edge strip 17 bent to the same arc is then placed on top of the partition plate 16. Because there are no gaps between the straight-edge brackets, some of the weld layer will be lost during cutting after welding, resulting in missing material on the sides and dimensional discrepancies on the brackets. This method ensures sufficient cutting allowance when separating the straight-edge brackets after welding. The brackets are clamped using the forming template shoulder clamp 8, and then the fixing limiting plate and the forming limiting plate are installed, enabling simultaneous welding of multiple straight-edge brackets and improving welding efficiency.

[0040] When multiple folded edge brackets are welded simultaneously, they are placed side by side, with a partition 16 of the corresponding size between each bracket according to the size of the folded edge. A Babbitt metal welding wire or Babbitt metal edge strip 17 bent to the same arc is then placed on top of the partition 16. Because the gaps between the folded edge brackets are relatively large, the molten metal during welding will leak out through these gaps. This method ensures that the molten metal does not leak out during welding and forms a good weld layer. The forming template shoulder clamp 8 is used to clamp the brackets, and then the fixing limit plate and the forming limit plate are installed, enabling simultaneous welding of multiple straight edge brackets and thus improving welding efficiency.

[0041] During the repair welding of the tomato, if the gap between the fixed limiting plate and the forming limiting plate is too large due to the original wear of the local side of the tomato after assembly, which may cause the liquid metal to be lost during welding, a thin ceramic fiber cloth can be placed between the base 10 and the fixed limiting plate at the position with the larger gap to reduce the gap and prevent the liquid metal from being lost during welding.

[0042] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
