Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, specifically to a pipe support welding mold. Background Technology

[0002] In the installation of piping systems such as industrial pipelines and building fire protection systems, pipe supports are crucial supporting components. Their fabrication typically involves welding structural steel (such as angle steel and channel steel) into a rectangular frame structure. Ensuring the dimensional accuracy (especially width) and perpendicularity of the final product is a critical technical aspect during the welding and assembly process of steel structures, pipe supports, or other metal frames. Traditional welding methods usually rely on the experience of pipe fitters or welders for manual layout, positioning, and welding, using simple tools such as right-angle rulers and measuring tapes for assistance.

[0003] However, the current method is prone to positioning errors, especially when performing multi-point and multi-angle welding. Errors accumulate, resulting in problems such as inconsistent width, twisting, or substandard verticality of the welded brackets. Secondly, each bracket needs to be measured, drawn, and aligned individually, which consumes a lot of time and results in low production efficiency. Thirdly, the quality of the finished product depends excessively on the technical level of the operators, making it impossible to achieve standardized and regulated production. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a pipe support welding mold that can effectively solve the problems mentioned in the background art.

[0005] The present invention adopts the following technical solution: a pipe support welding mold, comprising a frame body and multiple sets of positioning blocks. The frame body is composed of multiple legs and a rectangular worktable fixed to the top of the legs. The worktable surface is provided with scale lines. The multiple sets of positioning blocks include positioning block group one, positioning block group two and positioning block group three. The multiple sets of positioning blocks are fixedly installed on the edge of the worktable at preset positions, and together form a fixed cavity for clamping the support to be welded.

[0006] The positioning block group consists of multiple positioning blocks, which are fixedly arranged at intervals along one long side of the worktable and are used to position one long side of the bracket to be welded.

[0007] The second group of positioning blocks consists of multiple positioning blocks, which are symmetrically and fixedly set on the two short sides of the workbench to position the two short sides of the bracket to be welded.

[0008] The three positioning block groups consist of at least one positioning block, which is fixedly set on the other long side of the workbench opposite to the first positioning block group, and is used to position the bracket to be welded from the other side, working in conjunction with the first positioning block group.

[0009] The scale lines are used to assist in calibrating the dimensions of the bracket to be welded during the bracket welding process.

[0010] The workbench is welded from structural steel, and its surface is flattened to provide a stable welding reference surface.

[0011] The support to be welded is an angle steel or a channel steel.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the rigid cavity formed by the positioning block group ensures the relative position and included angle between the steel sections to be welded, and eliminates the verticality deviation problems such as frame twisting and rhomboid deformation caused by welding deformation. By changing the clamping position of the workpiece in the fixed cavity, the operator can weld brackets of different sizes and specifications, eliminating the need for repeated measurement and correction steps and shortening the production time of a single bracket. At the same time, the positioning relies on the same set of high-precision fixed positioning blocks and scale lines, avoiding systematic errors caused by using multiple different molds. The movement of the bracket ensures that the weld is always in the optimal welding position. Attached Figure Description

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] Please see Figure 1 , Figure 2 , Figure 3As shown, a pipe support welding mold includes a frame body and multiple sets of positioning blocks. The frame body consists of multiple legs 1 and a rectangular worktable 2 fixed to the top of the legs 1. The surface of the worktable 2 is provided with scale lines 21. The multiple sets of positioning blocks include positioning block group one 3, positioning block group two 4 and positioning block group three 5. The multiple sets of positioning blocks are fixedly installed on the frame of the worktable 2 at preset positions, and together form a fixed cavity for clamping the support to be welded.

[0017] The positioning block group 3 consists of multiple positioning blocks, which are fixedly arranged at intervals along one long side of the workbench 2 and are used to position one long side of the bracket to be welded.

[0018] The second positioning block group 4 consists of multiple positioning blocks, which are symmetrically and fixedly arranged on both short sides of the workbench 2 to position the two short sides of the bracket to be welded.

[0019] The positioning block group 3 5 consists of at least one positioning block, which is fixedly set on the other long side of the workbench 2 opposite to the positioning block group 1 3, and is used to position the bracket to be welded from the other side, working in conjunction with the positioning block group 1 3.

[0020] The scale line 21 is used to assist in calibrating the dimensions of the bracket to be welded during the bracket welding process.

[0021] The workbench 2 is welded from structural steel, and its surface is flattened to provide a stable welding reference surface.

[0022] The support to be welded is an angle steel or a channel steel.

[0023] Positioning block group 3, positioning block group 5 and positioning block group 4 are arranged perpendicular to each other. When the steel section is close to them, the included angle is strictly limited to 90 degrees, thus ensuring the squareness of the support frame on the horizontal plane and avoiding rhomboid deformation.

[0024] Workbench 2 provides a horizontal reference plane, ensuring that the support to be welded is level and flat.

[0025] One embodiment of this utility model: The main body of the mold is a sturdy welded frame, mainly composed of multiple support legs 1 and a rectangular worktable 2 fixed on its top. The worktable 2 is usually welded from channel steel, square steel and other shaped steel. Its upper surface is milled or ground to provide a stable reference plane. A scale line 21 is set in a prominent position on the surface of the worktable 2. The scale line can be used to quickly visually check whether the placement position of the steel to be welded is accurate before welding or during welding, and plays an auxiliary calibration role.

[0026] First, according to the size requirements of the target bracket, the operator places the first horizontal bracket 6 and the vertical bracket 7 close to the positioning block group 3 and the positioning block group 4. At this time, the clear scale line 21 on the edge of the workbench 2 can help the operator quickly and accurately adjust the steel to the predetermined position. After confirming that the position is correct, the welder can spot weld the intersection of the steel with the other steel that has been placed to initially form the bracket frame.

[0027] After spot welding one or two corners, move or flip the entire support frame on the workbench 2. For example, move the partially spot-welded support frame so that its long side on the other side aligns with positioning block group 3, or its short side aligns with positioning block group 4. Similarly, use the scale line 21 to ensure that the position after movement is accurate.

[0028] Under the new positioning reference, continue to position and spot weld the edges that were previously inconvenient to weld or newly aligned. By using this method of clamping once, welding on multiple sides, and then moving the workpiece and positioning it step by step, the precise positioning and welding of all the edges and corners and reinforcing ribs of the bracket can be completed gradually.

[0029] This allows for the continuous welding of new supports, eventually shaping the desired finished product.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
