Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of auxiliary equipment for spiral welded pipe production, specifically to a welding wire feeder for spiral welded pipe production. Background Technology

[0002] Spiral welded pipe is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain spiral angle, and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower steel strips. Its specifications are expressed by outer diameter and wall thickness. The welded pipe should ensure that the water pressure test, tensile strength of the weld and cold bending performance meet the requirements. The strength is generally higher than that of straight seam welded pipe. It can produce welded pipes with larger diameters with narrower blanks. In the production process of spiral welded pipe, a welding wire feeder is needed to support the winding rollers that wind the welding wire, thereby completing the welding work.

[0003] However, the existing wire feeding racks for spiral welded pipe production are not very flexible, cannot adjust the height of the winding roller, and when the wire is not in use, the wire on the outside of the winding roller is easily dropped due to gravity.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0035] like Figures 1-4 As shown, it illustrates a welding wire feeder for spiral welded pipe production according to an embodiment of the present disclosure, comprising:

[0036] The base plate 1 and the base frame 2 are fixed to the surface of the base plate 1;

[0037] The winding roller 3 and the clamping mounting assembly 5 are provided. The winding roller 3 is mounted on the base frame 2, and the clamping mounting assembly 5 is mounted in the base frame 2.

[0038] A pair of uprights 4 and a fastening assembly 6, the uprights 4 are fixed to the surface of the base plate 1, and the fastening assembly 6 is set on the uprights 4;

[0039] The clamping and mounting assembly 5 includes a pair of grooves 5-1, which are formed at both ends of the top of the base frame 2. Several rolling wheels 5-2 are rotatably connected in the grooves 5-1. The winding roller 3 is placed on the rolling wheels 5-2. A pair of side frames 5-3 are rotatably connected to the bottom of the base frame 2 via pins. A spring 5-4 is connected between the side frames 5-3 and the base frame 2. A bottom groove 5-5 is formed at the bottom of the base frame 2. A pair of telescopic cylinders 5-6 are set in the bottom groove 5-5. A pressure plate 5-7 is set at the output end of the telescopic cylinders 5-6. A pressing block 5-8 is rotatably connected to the upper end of the side frame 5-3. The pressing blocks 5-8 are respectively inserted into both ends of the winding roller 3. A drive motor 5-9 is installed on one side of the side frame 5-3. The output end of the drive motor 5-9 is connected to the pressing block 5-8.

[0040] In some examples, to achieve the effect of tightening the winding roller 3 and maintaining stable rotation, a tightening assembly 6 is designed. This assembly includes a pair of grooves 5-1 at both ends of the top of the base frame 2. Several rolling wheels 5-2 are rotatably connected in the grooves 5-1 for placing the winding roller 3, allowing the winding roller 3 to roll on the rolling wheels 5-2. A pair of side frames 5-3 are rotatably connected to the bottom of the base frame 2 via pins. A spring 5-4 is connected between the side frames 5-3 and the base frame 2, providing a certain strength of tension. A bottom groove 5-5 is also provided at the bottom of the base frame 2. A pair of telescopic cylinders 5-6 are installed in the bottom groove 5-5, and a pressure plate is provided at the output end of the telescopic cylinders 5-6. 5-7 When the telescopic cylinder 5-6 is working, it can push the pressure plate 5-7 to rise or fall. When it rises, it will press against the side frame 5-3. The side frame 5-3 rotates outward through the pin connection and opens. In the open state, the winding roller 3 can be put in and taken out. The upper end of the base frame 2 is rotatably connected to the clamping block 5-8. The clamping block 5-8 is inserted into both ends of the winding roller 3 to fix and clamp both ends of the winding roller 3. One side of the base frame 2 is equipped with a drive motor 5-9. The output end of the drive motor 5-9 is connected to the clamping block 5-8. The drive motor 5-9 can drive the clamping block 5-8 to rotate, which can control the rotation of the winding roller 3 and actively release the welding wire.

[0041] like Figures 1-4 As shown, this embodiment proposes a tightening assembly 6 including a central cover 6-1, which is fixed to the top of the support frame 4. A rectangular cover 6-2 is provided on the side end face of the central cover 6-1. The connection between the rectangular cover 6-2 and the interior of the central cover 6-1 is an arc-shaped transition structure. A pair of long grooves 6-3 are opened on the surface of the rectangular cover 6-2. A round rod 6-4 and a screw 6-5 are respectively provided in the long grooves 6-3. A sliding frame 6-6 is connected to both the round rod 6-4 and the screw 6-5. The screw 6-5 and the sliding frame 6-6 are connected by a threaded engagement. A stabilizing sleeve 6-7 is connected between the sliding frames 6-6.

[0042] In some examples, to achieve the effect of keeping the welding wire in a centered position during release, a clamping assembly 6 is designed. This assembly includes a central cover 6-1 fixed to the top of the support frame 4. A rectangular cover 6-2 is provided on the side end face of the central cover 6-1, and the connection between the rectangular cover 6-2 and the interior of the central cover 6-1 adopts an arc-shaped transition structure. This transition makes the release of the welding wire smoother. A pair of long grooves 6-3 are formed on the surface of the rectangular cover 6-2. A round rod 6-4 and a screw 6-5 are respectively arranged in these two long grooves 6-3. Sliding brackets 6-6 are connected to both screw 6-4 and screw 6-5. Screw 6-5 and sliding brackets 6-6 are connected by a threaded connection. When screw 6-5 rotates, sliding brackets 6-6 will move along screw 6-5. At the same time, in conjunction with round rod 6-4, the movement of sliding brackets 6-6 will remain stable and the angle will remain unchanged. A stabilizing sleeve 6-7 is connected between the two sliding brackets 6-6. As sliding brackets 6-6 move, welding wire can pass through stabilizing sleeve 6-7. The height of welding wire feeding can be adjusted through stabilizing sleeve 6-7.

[0043] For example, such as Figure 3 As shown, section 6-7 of the stabilizing sleeve has a funnel-shaped opening structure.

[0044] In some examples, a flared opening structure makes the opening smoother and reduces wear on the welding wire.

[0045] For example, such as Figure 1 As shown, the central cover 6-1 has a triangular structure, and the central cover 6-1 is at the same height as the winding roller 3.

[0046] In some examples, a triangular structure is used to increase the opening range, which is combined with the repeated left and right movement when the welding wire is released.

[0047] For example, such as Figure 1 As shown, the inside of groove 5-1 is an arc-shaped concave structure, and the curvature inside groove 5-1 matches the curvature of the surface of winding roller 3.

[0048] In some examples, the rolling mechanism of the winding roller 3, combined with the arc-shaped structure, and the support of multiple points on the roller, makes the rolling more stable.

[0049] For example, such as Figure 4 As shown, the connection between the clamping block 5-8 and the winding roller 3 is a conical structure, and the surface of the clamping block 5-8 is an anti-slip surface.

[0050] In some examples, the conical structure, combined with the arc-shaped movement trajectory of the clamping block 5-8 and the side frame 5-3, makes insertion easier.

[0051] For example, such as Figure 4As shown, the surface of the rolling wheel 5-2 has a concave structure, and the size of the concave part of the surface of the rolling wheel 5-2 is the same as the thickness of the winding roller 3.

[0052] In some examples, the concave structure allows the winding roller 3 to be supported internally by an embedded method, making it more stable.

[0053] In actual use: First, adjust the position of the stabilizing sleeve 6-7 in the clamping assembly 6 according to the requirements. Rotate the screw 6-5 to move the sliding frame 6-6 on the round rod 6-4 and the screw 6-5, thereby adjusting the height of the stabilizing sleeve 6-7. First, start the telescopic cylinder 5-6 to pull the pressure plate 5-7. The pressure plate 5-7 presses against the side frame 5-3 to open to both sides. Then, place the winding roller 3 on the rolling wheel 5-2 of the clamping assembly 6. Start the telescopic cylinder 5-6 again, and the pressure plate 5-7 descends. The side frame 5-3, through the tension of the spring 5-4, inserts the clamping block 5-8 into both ends of the winding roller 3. The clamping block 5-8 fixes the winding roller 3. Start the drive motor 5-9 to drive the clamping block 5-8 to rotate, so that the winding roller 3 rotates to release the welding wire. The welding wire passes through the stabilizing sleeve 6-7 and is guided by the central cover 6-1 and the rectangular cover 6-2 to maintain stable material supply.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
