Description

Technical Field

[0001] The invention relates to the field of metal pipe welding, in particular to an anti-deformation tool for metal pipe welding. Background Art

[0002] Currently, metal pipe welding is a common and important process in modern industrial manufacturing. However, due to the high temperature during welding, metal pipes often deform, which not only affects the appearance quality of the product, but also reduces its structural strength and service life.

[0003] Prior to welding, the metal pipe is limited. However, the limitation is generally only performed for metal pipes of one size. When the size of the metal pipe changes, the limiting structure needs to be reinstalled, which is not practical. Summary of the Invention

[0004] In order to improve the applicability of the limiting structure and enhance processing efficiency, the present application provides an anti-deformation tool for metal pipe welding.

[0005] The present application provides an anti-deformation tool for metal pipe welding, which adopts the following technical solution:

[0006] A deformation prevention tool for metal pipe welding includes a workbench and a pair of pressure plates. The two pressure plates are arranged horizontally and located directly above the table surface of the workbench. The two pressure plates are arranged horizontally at intervals. The position between the pressure plates and the workbench is a positioning space, and the positioning space is used for metal pipes to pass through. The workbench is equipped with a driving component for driving the pressure plates to move toward or away from the workbench.

[0007] By adopting the above technical solution, when welding is required, the two ends of the metal pipe are first inserted into the two positioning spaces, and then the driving assembly drives the pressure plate to move toward the workbench until the two ends of the metal pipe are clamped, so that the branch pipe can be welded between the two ends of the metal pipe, which greatly reduces the deformation of the metal pipe during the welding process and reduces subsequent pyrotechnics and profiling processing; and the pressure plate can be driven to move to meet the positioning of metal pipes of different sizes and specifications, thereby improving the applicability of the limiting structure and thus improving processing efficiency.

[0008] Preferably, the driving assembly includes a plurality of screws and a plurality of limit nuts, and the plurality of screws are respectively arranged on both sides of the positioning space, one end of the screw is installed on the workbench, and the other end extends vertically upward; the pressure plate is provided with a through hole, and the screw is passed through the through hole in the pressure plate; a limit nut is threadedly installed on each of the screws, and the limit nut abuts against the side of the pressure plate away from the workbench.

[0009] By adopting the above technical solution, when the two ends of the metal tube are stuck in the positioning space, the limit nut can be rotated to push the pressure plate down to position the metal tube; when welding is completed, the limit nut can be rotated in the opposite direction to make the pressure plate move vertically upward until the pressure plate is removed from the screw and the product can be taken out; the structure is simple, and the limiting effect of the limit nut makes the pressure plate more stable.

[0010] Preferably, a pair of the screw rods is provided on each side of the positioning space, and the two screw rods of the same pair are spaced apart from each other in the arrangement direction of the two pressing plates.

[0011] By adopting the above technical solution, the pressure at each position of the pressure plate is made more constant, thereby improving the limiting stability of the metal pipe.

[0012] Preferably, a protective plate is laid on the table top of the workbench and on the line connecting the positioning spaces.

[0013] By adopting the above technical solution, the position strength of the workbench for positioning the metal pipe can be improved.

[0014] Preferably, the protection plate is located between the two positioning spaces and has a convex limiting section.

[0015] By adopting the above technical solution, since there will be different degrees of concave deformation at the welding point of the metal pipe when the metal pipe is welded, the upper convex limiting section can be set to support the deformed position of the metal pipe, thereby further reducing the deformation of the metal pipe during the welding process.

[0016] Preferably, the pressure plate is provided with a retaining ring at a position corresponding to each of the through holes, and the retaining ring extends along the circumference of the through hole.

[0017] By adopting the above technical solution, when the pressure plate needs to be mounted on each screw, the top end of each screw can be clamped into the clamping ring first, and then the pressure plate can be pressed synchronously, so that each screw can pass through accurately and smoothly, reducing the offset when the screw is aligned with each perforation in turn.

[0018] Preferably, the inner ring of the retaining ring away from one end of the pressure plate is provided with a guide surface extending circumferentially.

[0019] By adopting the above technical solution, the top end of the screw can be inserted into the retaining ring more smoothly.

[0020] Preferably, the workbench includes a plate surface, support rods and connecting rods, the support rods are arranged at circumferential intervals along the bottom of the plate surface, and the support rods are arranged vertically; the connecting rods are installed at the bottom between two adjacent support rods, and the two ends of the connecting rods are respectively connected to the support rods.

[0021] By adopting the above technical solution, the overall structure is made more stable, thereby improving the stability of the welding structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When welding is required, first insert the two ends of the metal pipe into the two positioning spaces, then use the drive assembly to drive the pressure plate to move towards the workbench until the two ends of the metal pipe are clamped, so that the branch pipe can be welded between the two ends of the metal pipe, greatly reducing the deformation of the metal pipe during welding, and reducing subsequent ignition and shape correction processing; and by driving the pressure plate to move, it can meet the positioning of metal pipes of different sizes, improve the applicability of the limit structure, and thus improve processing efficiency;

[0024] 2. Since there will be a slight concave deformation at the welding point of the metal pipe when it is welded, the convex limiting section can be set to support the deformed position of the metal pipe, thereby further reducing the deformation of the metal pipe during the welding process.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a deformation prevention tool for metal pipe welding. Figure 1 and Figure 2The anti-deformation tooling includes a workbench 1 and a pair of pressing plates 2. The surface of the workbench 1 is extended horizontally. The pressing plates 2 are rectangular plates. The two pressing plates 2 are horizontally arranged. The two pressing plates 2 are located directly above the surface of the workbench 1. The two pressing plates 2 are respectively located at both ends of the surface of the workbench 1. The position between the pressing plates 2 and the workbench 1 is a positioning space 3, which is used for the metal pipe to pass through.

[0032] The workbench 1 is equipped with a drive assembly 4, which includes a plurality of screws 41 and a plurality of limit nuts 42. The number of the screws 41 is consistent with the number of the limit nuts 42. In this embodiment, there are two pairs of screws 41, and the two pairs of screws 41 are respectively arranged at the two sides of the positioning space 3. The two screws 41 of the same pair are spaced apart in the arrangement direction of the two pressure plates 2. The four screws 41 correspond to the four corners of the pressure plate 2 respectively. One end of the screw 41 is fixedly mounted on the workbench 1 by welding, and the other end extends vertically upward; the pressure plate 2 is provided with a through hole 21, and the screw 41 is passed through the pressure plate 2 through the through hole 21; each limit nut 42 is threadedly mounted on each screw 41, and the limit nut 42 abuts against the side of the pressure plate 2 away from the workbench 1.

[0033] Therefore, after the two ends of the metal tube are respectively inserted into the two positioning spaces 3, the pressure plate 2 is placed on the screw rod 41, and then the limit nut 42 is threadedly installed on each screw rod 41 until the pressure plate 2 presses the metal tube firmly; subsequently, the branch pipe can be welded at the position where the metal tube is located between the two positioning spaces 3.

[0034] Reference Figure 1 and Figure 2 The workbench 1 includes a plate surface 11, a support rod 12 and a connecting rod 13. The plate surface 11 is arranged horizontally and is a rectangular plate; four support rods 12 are provided, and the four support rods 12 are arranged at the four corners of the plate surface 11 along the circumferential direction. One end of the support rod 12 is fixedly installed on the bottom of the workbench 1 by welding, and the other end extends vertically downward; a connecting rod 13 is fixedly installed at the bottom between two adjacent support rods 12, and the connecting rod 13 is arranged horizontally. The two ends of the connecting rod 13 are fixedly installed on the support rod 12 by welding.

[0035] Reference Figure 1 and Figure 2 A protective plate 14 is fixedly installed on the plate surface 11 by welding. The protective plate 14 is arranged between the two pairs of screws 41 connecting the same pressing plate 2, and the protective plate 14 is laid on the connecting line of the two positioning spaces 3; the protective plate 14 is located between the two positioning spaces 3 and has a convex limiting section 15, thereby limiting the concave deformation of the welding position during welding.

[0036] Reference Figure 2 and Figure 3A retaining ring 22 is fixedly installed on the side of the pressure plate 2 away from the limit nut 42 and at the position corresponding to each through-hole 21. The retaining ring 22 extends along the circumference of the through-hole 21, so that each screw 41 can pass through the pressure plate 2 from each through-hole 21 more quickly; the inner ring of the retaining ring 22 away from one end of the pressure plate 2 is provided with a guide surface 23 extending along the circumference.

[0037] The implementation principle of the anti-deformation tooling for metal pipe welding in the embodiment of the present application is: when welding is required, first insert the two ends of the metal pipe into the two positioning spaces 3, then make the top end of each screw 41 be clamped into the corresponding clamping ring 22, and then synchronously make the screw 41 pass through each through-hole 21, and finally, thread the limit nut 42 on each screw 41 until the pressure plate 2 presses the metal pipe firmly, so that the branch pipe can be welded between the two ends of the metal pipe.
