Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and more specifically, to a welding and forming device for guardrail mesh. Background Technology

[0002] Fences are widely used in railways, highways, bridges, factories and other places. They are mainly made of longitudinal and transverse wires welded together. Fence welding and forming equipment is an automated or semi-automated equipment used to produce various fence products and is used in the manufacture of protective and isolation facilities.

[0003] Traditional welding equipment has a fixed welding head position, which cannot be adapted to fences with different mesh sizes. The process of changing welding fixtures is cumbersome and lacks versatility. The number of welding nodes is not fixed and it is difficult to deal with flexibly. The mesh is prone to displacement during the welding process, resulting in problems such as weak welding points, incomplete welding, and misaligned welding, which affect the welding quality. The degree of welding automation is low and the production efficiency is low.

[0004] In summary, to achieve efficient, precise, and automated welding of guardrail mesh, it is necessary to address the problems of poor versatility, unstable mesh positioning, and low automation in existing guardrail mesh welding and forming devices, so that the welding and forming devices can be adapted to guardrail mesh of various specifications. Utility Model Content

[0005] The problem to be solved by the fence welding and forming device provided by this utility model is that the existing fence welding and forming devices have poor versatility, unstable mesh positioning, and low degree of automation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fence welding and forming device, including a workbench, a fence blank being provided at the upper end of the workbench, support frames being symmetrically fixedly connected to the upper end of the workbench, an mounting frame being slidably connected between the two support frames, a lifting cylinder being fixedly connected to the lower end of the inner wall of the mounting frame, an adjusting frame being fixedly connected to the output end of the lifting cylinder, the lifting cylinder being used to drive the adjusting frame to lift, a threaded rod being rotatably connected inside the adjusting frame, a fixed slide, a driven slide, and a driving slide being slidably connected to the front end of the adjusting frame, a welding head being fixedly connected to the front end of the fixed slide, the driven slide, and the driving slide through a connecting block, and limit seats being slidably connected to the upper end of the workbench and on both sides of the fence blank, with a pusher pulley being rotatably connected to the end of the limit seat near the fence blank.

[0007] In a preferred embodiment, a fixing rod is fixedly connected inside the left support frame, and the fixing rod moves through the left end of the mounting frame. A threaded rod is fixedly connected inside the right support frame, and the outer side of the threaded rod is threadedly connected to the right end of the mounting frame.

[0008] In a preferred embodiment, a movable motor is fixedly connected to the outer side of the right support frame, and the output shaft of the movable motor is fixedly connected to the lead screw. The movable motor is used to drive the lead screw to rotate.

[0009] In a preferred embodiment, an adjustment motor is fixedly connected to the right end of the adjustment frame. The output shaft of the adjustment motor is fixedly connected to the threaded rod. The adjustment motor is used to drive the threaded rod to rotate. Both the fixed slide and the driven slide are slidably connected to the threaded rod. The drive slide and the threaded rod are threadedly connected.

[0010] In a preferred embodiment, a connecting plate is fixedly connected to the upper end of the fixed slide, and a fastening bolt is threadedly connected to the upper end of the connecting plate. The lower end of the fastening bolt is adapted to the upper end of the adjusting bracket.

[0011] In a preferred embodiment, both the fixed slide and the driving slide are rotatably connected to a short connecting rod at their front ends, and both driven slides are rotatably connected to a long connecting rod at their front ends. One end of two adjacent long connecting rods is rotatably connected via a pivot, and the other end of the long connecting rod is rotatably connected to the short connecting rod via a pivot.

[0012] In a preferred embodiment, electric push rods are fixedly connected to both the front and rear ends of the upper end of the worktable via mounting plates. The output end of the electric push rod is fixedly connected to the limit seat. The electric push rod is used to drive the limit seat to move. The surface of the pusher pulley is provided with an anti-slip rubber pad layer.

[0013] The beneficial effects of this utility model are as follows: This invention establishes a stable adjustment benchmark through the rotation of the threaded rod and the positioning of the fixed slide. In conjunction with the linkage between the short and long connecting rods, it drives the driven slide and the driving slide to move synchronously, achieving rapid and precise adjustment of the welding head spacing. The adjustment is flexible and stable, and it can adapt to the welding needs of fence mesh with different mesh sizes without changing the tooling. This broadens the application range of the equipment and improves its versatility and production efficiency.

[0014] This invention uses a pusher pulley to clamp and position the fence blank, preventing the mesh from shifting during welding and ensuring welding quality. The mounting frame slides back and forth, driving the welding heads to weld in batches. After a group of welds is completed, the pusher pulley pushes the mesh to the left, and the operation is repeated until the overall welding is completed. It has a high degree of automation, precise positioning, stable welding, and improved welding efficiency. Attached Figure Description

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 The guardrail welding and forming device includes a workbench 1, with a guardrail blank 2 placed on the upper end of the workbench 1. Support frames 3 are symmetrically fixedly connected to the upper end of the workbench 1. An installation frame 4 is slidably connected between the two support frames 3. A lifting cylinder 5 is fixedly connected to the lower end of the inner wall of the installation frame 4. An adjusting frame 6 is fixedly connected to the output end of the lifting cylinder 5. The lifting cylinder 5 is used to drive the adjusting frame 6 to lift. A threaded rod 7 is rotatably connected inside the adjusting frame 6. A fixed slide 8, a driven slide 9, and a driving slide 10 are slidably connected to the front end of the adjusting frame 6. Welding heads 11 are fixedly connected to the front ends of the fixed slide 8, driven slide 9, and driving slide 10 through connecting blocks. Limit seats 12 are slidably connected to the upper end of the workbench 1 and located on both sides of the guardrail blank 2. A pusher pulley 13 is rotatably connected to the end of the limit seat 12 near the guardrail blank 2.

[0023] It should be noted that the extension and retraction of the lifting cylinder 5 can drive the adjusting frame 6 to lift and lower, thereby adjusting the height of the welding head 11 to adapt to the welding requirements of guardrail blanks 2 of different thicknesses. The pusher pulley 13 assists in pushing the welded guardrail to the left, realizing automated displacement and unloading.

[0024] Refer to the instruction manual appendix Figure 2The left support frame 3 has a fixed rod 14 inside, and the fixed rod 14 moves through the left end of the mounting frame 4. The right support frame 3 has a screw rod 15 inside, and the outside of the screw rod 15 is threaded to the right end of the mounting frame 4.

[0025] It should be noted that the rotation of the lead screw 15 drives the mounting bracket 4 to move back and forth, and the fixing rod 14 plays a guiding role, so as to adjust the position of the welding head 11 in the horizontal direction, so as to weld the welding points at different positions.

[0026] Refer to the instruction manual appendix Figure 2 A movable motor 16 is fixedly connected to the outer side of the right support frame 3. The output shaft of the movable motor 16 is fixedly connected to the lead screw 15. The movable motor 16 is used to drive the lead screw 15 to rotate.

[0027] It should be noted that the moving motor 16 drives the lead screw 15 to rotate.

[0028] Refer to the instruction manual appendix Figure 3 An adjustment motor 17 is fixedly connected to the right end of the adjustment frame 6. The output shaft of the adjustment motor 17 is fixedly connected to the threaded rod 7. The adjustment motor 17 is used to drive the threaded rod 7 to rotate. The fixed slide 8 and the driven slide 9 are both slidably connected to the threaded rod 7. The drive slide 10 is threadedly connected to the threaded rod 7.

[0029] It should be noted that adjusting the motor 17 drives the threaded rod 7 to rotate, and driving the slide block 10 to move along the axial direction of the threaded rod 7.

[0030] Refer to the instruction manual appendix Figure 4 A connecting plate 18 is fixedly connected to the upper end of the fixed slide 8, and a fastening bolt 19 is threadedly connected to the upper end of the connecting plate 18. The lower end of the fastening bolt 19 is adapted to the upper end of the adjusting bracket 6.

[0031] It should be noted that tightening the fastening bolt 19 will fix the connecting plate 18 and the fixed slide 8 onto the adjusting frame 6.

[0032] Refer to the instruction manual appendix Figure 4 Both the fixed slide 8 and the drive slide 10 are rotatably connected to a short connecting rod 20 at their front ends, and both the driven slide 9 are rotatably connected to a long connecting rod 21 at their front ends. One end of two adjacent long connecting rods 21 are rotatably connected by a pivot, and the other end of the long connecting rod 21 is rotatably connected to the short connecting rod 20 by a pivot.

[0033] It should be noted that, through the connection of the short connecting rod 20 and the long connecting rod 21, the movement of the drive slide 10 will drive the driven slide 9 to move synchronously, thereby realizing the flexible adjustment of the spacing between each welding head 11 to adapt to the welding of guardrail mesh with different mesh sizes.

[0034] Refer to the instruction manual appendix Figure 5Electric push rods 22 are fixedly connected to the front and rear ends of the upper end of the worktable 1 via mounting plates. The output end of the electric push rod 22 is fixedly connected to the limit seat 12. The electric push rod 22 is used to drive the limit seat 12 to move. The surface of the pusher pulley 13 is provided with an anti-slip rubber pad.

[0035] It should be noted that the electric push rod 22 pushes the limit seat 12 to move, the push pulley 13 clamps the fence blank 2, and the sliding rubber pad increases the friction to prevent the fence from shifting during the welding process.

[0036] Working principle: Tighten the fastening bolt 19 to fix the position of the slide block 8. Adjust the motor 17 to drive the threaded rod 7 to rotate, driving the slide block 10 to move along the threaded rod 7. Under the action of the short connecting rod 20 and the long connecting rod 21, the driven slide block 9 moves synchronously. Adjust the spacing between the welding heads 11 according to the specifications of the fence to be welded to improve the applicability of welding. Place the fence blank 2 on the workbench 1. The two electric push rods 22 push the limit seat 12 to move in opposite directions. The pusher pulley 13 clamps the fence blank 2 to achieve precise positioning. The moving motor 16 drives the lead screw 15 to rotate, so that the mounting frame 4 slides back and forth along the fixed rod 14. The lifting cylinder 5 drives the welding heads 11 to weld in batches in sequence. After one group of fence blanks 2 is welded, the pusher pulley 13 pushes the fence blank 2 to the left to carry out the next group of welding work until the welding is completed, and the material is automatically unloaded. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
