Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a welding wire feeding turntable device. Background Art

[0002] Large-diameter steel pipes used in deep-sea construction are usually welded after spiral splicing of steel plates, so welding wire is needed. Since the weld seam of large-diameter steel pipes is long, more welding wire is required. Conventional welding wire reels are small, and they need to be replaced more frequently and at a faster frequency, which affects welding efficiency.

[0003] In the related art, a specific large turntable is used as a feeding tray for welding wire. The size of the feeding tray is much larger than that of a conventional welding wire tray, so that it can wind more welding wire and drive the welding wire for feeding. In addition, due to the large size of the feeding tray and the small space in the working area where there are welding equipment, it is not easy to place the feeding tray. Therefore, the place where the feeding tray is placed needs to be separated from the working area by a certain distance.

[0004] When a day's welding work is finished, it is usually necessary to rewind the welding wire between the loading tray and the welding equipment on the loading tray. When winding, the worker needs to rotate the loading tray, but at this time there is no tension on the end of the welding wire, which makes it easy for the welding wire rewound on the loading tray to be pressed or entangled with each other. Therefore, another worker needs to apply a pulling force to the end of the welding wire, which makes it inconvenient to rewind the welding wire on the loading tray. Utility Model Content

[0005] In order to improve the convenience of recycling welding wire on a loading tray, the present application provides a welding wire loading turntable device.

[0006] The present application provides a welding wire feeding turntable device, which adopts the following technical solution:

[0007] A welding wire feeding turntable device comprises a welding wire turntable, a support frame and an elastic resistance component, wherein the welding wire turntable is rotatably mounted on the support frame, a mounting frame extending outward is mounted on the support frame, and two groups of the elastic resistance components are symmetrically arranged, and the two groups of the elastic resistance components are mounted on the mounting frame to provide clamping resistance for the welding wire rewound on the welding wire turntable.

[0008] In order to provide a damping force to the welding wire rewound on the welding wire turntable, the elastic resistance component includes a clamping block, and the two clamping blocks in the two groups are provided with wire passing grooves that are interconnected and allow the welding wire to pass through on their adjacent sides.

[0009] In order to enable the welding wire to smoothly enter the wire slot at the beginning of the rewinding process and obtain a clamping damping force as it moves, the wire slot is a conical slot, and the slot diameter of the wire slot close to the welding wire turntable is smaller than the slot diameter of the wire slot away from the welding wire turntable.

[0010] In order to increase the damping force provided by the clamping block to the welding wire, a damping rubber pad is arranged on the groove wall of the wire passing groove.

[0011] In order to automatically provide a clamping damping force for the welding wire when rewinding the welding wire to improve convenience, the elastic resistance component also includes a driving spring that drives the two clamping blocks to approach each other.

[0012] In order to reduce the damping force exerted by the elastic resistance component of the wire turntable on the welding wire during the wire unwinding process, the mounting frame is provided with an adjusting component for driving the two clamping blocks to move away from each other so that the welding wire can smoothly pass through the wire slot.

[0013] The adjustment assembly includes a fixing plate fixedly mounted on the mounting frame and an adjusting column threadedly mounted on the fixing plate and insertable into the wire slot, the adjusting column is located on the side of the clamping block away from the welding wire turntable, and a wire threading hole for inserting the welding wire is provided on the side of the adjusting column close to the clamping block, and the aperture of the wire threading hole is larger than the diameter of the welding wire.

[0014] The adjusting column comprises a threaded column threadedly mounted on the fixing plate and a conical head inserted into the thread passing groove to drive the two clamping blocks to move away from each other.

[0015] In order to facilitate a forklift or a gantry crane to lift the welding wire turntable for replacement, a lifting ring plate for inserting a fork arm or a hook of a forklift is installed on the welding wire turntable through bolts.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] When the welding wire between the welding wire turntable and the welding equipment needs to be rewound on the welding wire turntable after the work is finished, only one worker needs to reversely rotate the welding wire turntable. During the reverse rotation of the welding wire turntable, the elastic resistance component will provide a damping tension to the welding wire that is about to be wound on the welding wire turntable, thereby preventing the wire from being pressed or tangled.

[0018] The wire slot is set as a tapered slot, so that the welding wire can smoothly enter the wire slot at the beginning during the rewinding process, and then obtain a clamping damping force as it moves. In addition, the setting of the damping rubber pad increases the damping force when the welding wire passes through the wire slot;

[0019] During welding, when the wire turntable is releasing the wire normally, turn the adjusting column to insert the conical head into the wire slot to drive the two clamping blocks away from each other, thereby enlarging the wire slot so that the welding wire will not be easily affected by the damping force and can pass through the wire slot more smoothly.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses a welding wire feeding turntable device. Figure 1 and Figure 2 The welding wire feeding turntable device includes a welding wire turntable 1, a support frame 2 and an elastic resistance component 3. The welding wire turntable 1 is rotatably mounted on the support frame 2, and the welding wire turntable 1 can be disassembled from the support frame 2, so that the welding wire on the welding wire turntable 1 located on the support frame 2 can be directly replaced after use. A mounting frame 21 is provided on the support frame 2, and the elastic resistance component 3 is provided on the mounting frame 21 and is spaced a certain distance from the welding wire turntable 1. When the welding wire turntable 1 is reversed to make the external welding wire rewound on the welding wire turntable 1, the elastic resistance component 3 will provide a damping force to the welding wire at this time, so that the welding wire between the welding wire turntable 1 and the elastic resistance component 3 is in a relatively straight state, so that the welding wire is not easy to be pressed (referring to the upper and lower layers of welding wires being staggered and stacked) or entangled and knotted due to relaxation after being wound on the welding wire turntable 1. At the same time, only one staff member is needed to reverse the welding wire turntable 1, thereby improving the convenience of the feeding tray when recycling welding wire.

[0027] The two ends of the welding wire turntable 1 are fixedly installed with a rotating shaft 11, and the top of the support frame 2 is provided with a semi-circular notch. The rotating shaft 11 is sleeved with a bearing and embedded in the notch, so that the welding wire turntable 1 is rotatably installed on the support frame 2. The end of the welding wire turntable 1 is also installed with a lifting ring plate 12 by bolts. The fork arm of the forklift can be inserted into the lifting ring to fork the welding wire turntable 1 for replacement. At the same time, the hook of the gantry crane can also hook the lifting ring plate 12 to lift the welding wire turntable 1 for replacement. After the replacement of the welding wire turntable 1 is completed, the lifting ring plate 12 can be removed, reducing the risk of the lifting ring plate 12 interfering with the support frame 2.

[0028] Reference Figure 1 and Figure 2 , the mounting frame 21 extends in the horizontal direction away from the support frame 2, and then the side of the mounting frame 21 away from the support frame 2 will be separated from the welding wire turntable 1 by a certain distance. The elastic resistance component 3 is located on the side of the mounting frame 21 away from the support frame 2, so that the welding wire between the welding wire turntable 1 and the elastic resistance component 3 can be in a straight state. Among them, there are two groups of elastic resistance components 3, and the two groups of elastic resistance components 3 have the same structure and are symmetrically arranged. The welding wire will pass between the two groups of elastic resistance components 3, so the two groups of elastic resistance components 3 will clamp the welding wire to generate a damping force. The mounting frame 21 is provided with a wire hole for the welding wire to pass through. After the welding wire passes through the wire hole, it will be located between the two groups of elastic resistance components 3. The following is explained by taking one group of elastic resistance components 3 as an example.

[0029] Reference Figure 2 and Figure 3 The elastic resistance assembly 3 includes a clamping block 31, a driving spring 32 and an abutting plate 33. The abutting plate 33 is welded to the mounting frame 21. The driving spring 32 is located between the clamping block 31 and the abutting plate 33, and one end of the driving spring 32 is fixed to the clamping block 31; the other end is fixed to the abutting plate 33. The two clamping blocks 31 move toward each other through the corresponding driving springs 32, thereby clamping the welding wire.

[0030] Combination Figure 1 Reference Figure 3 and Figure 4 , a wire passing groove 34 is provided on the side where the two clamping blocks 31 are close to each other, and the wire passing groove 34 passes through the clamping blocks 31 along the direction of movement of the welding wire. The wire passing grooves 34 on the two clamping blocks 31 are connected to each other, and the wire passing grooves 34 on the two clamping blocks 31 are spliced ​​to form a tapered groove, that is, the groove diameter of the wire passing groove 34 close to the welding wire turntable 1 is smaller than the groove diameter of the wire passing groove 34 away from the welding wire turntable 1. In addition, damping rubber pads 35 are glued to the groove walls of the wire passing grooves 34. Since a tapered groove is formed after the two wire passing grooves 34 are spliced, the damping rubber pads 35 in the two wire passing grooves 34 will also be tapered after splicing. The welding wire passes between the two damping rubber pads 35.

[0031] Among them, the notch of the wire slot 34 close to one end of the welding wire turntable 1 is slightly smaller than the diameter of the welding wire under the action of the damping rubber pad 35, so that the damping rubber pad 35 can wrap the welding wire to generate a damping force.

[0032] Combination Figure 2 Reference Figure 3 and Figure 4 A side of the mounting frame 21 on which the elastic resistance component 3 is arranged is also provided with an adjustment component 22. The adjustment component 22 can drive the two clamping blocks 31 to move away from each other, thereby increasing the diameter of the slots at both ends of the wire slot 34, so that when the welding wire turntable 1 is loaded, the welding wire can smoothly pass through the wire slot 34, making it difficult for the welding wire to rub against the damping rubber pad 35 to generate resistance.

[0033] The adjustment assembly 22 includes a fixing plate 23 and an adjustment column 24. The fixing plate 23 and the abutment plate 33 are located on the same side of the mounting frame 21, and the fixing plate 23 is welded to the mounting frame 21. The adjustment column 24 is located on the side of the clamping block 31 away from the mounting frame 21 along the direction of the welding wire movement, and the adjustment column 24 is threadedly mounted on the fixing plate 23. After the adjustment column 24 moves, it can be inserted into the wire slot 34, thereby driving the two clamping blocks 31 to move away from each other.

[0034] Combination Figure 2 Reference Figure 3 and Figure 4 The fixing plate 23 is an L-shaped plate body, and a plate body of the fixing plate 23 is located on the side of the clamping block 31 away from the mounting frame 21 and is arranged at intervals with the clamping block 31. The adjusting column 24 includes a threaded column 25 and a conical head 26. The conical head 26 is located at one end of the threaded column 25 and the threaded column 25 and the conical head 26 are integrally formed. The outer diameter of the conical column close to the clamping block 31 is smaller than the outer diameter of the conical column close to the threaded column 25. The conical column is located between the fixing plate 23 and the clamping block 31. The fixing plate 23 is provided with a threaded hole that penetrates the fixing plate 23, and the threaded column 25 is threadedly inserted into the threaded hole. The end of the conical head 26 away from the threaded column 25 is provided with a threading hole 27 for the welding wire to pass through. The threading hole 27 penetrates the conical head 26 and the threaded column 25, and the aperture of the threading hole 27 is larger than the diameter of the welding wire. The threaded column 25 is rotated to drive the conical head 26 to be inserted into the thread groove 34. As the conical head 26 goes deeper, the two clamping blocks 31 will move away from each other.

[0035] The implementation principle of a welding wire feeding turntable device in an embodiment of the present application is: when the welding wire turntable 1 is normally feeding, the threaded column 25 is rotated to insert the conical head 26 into the wire slot 34 and drive the two clamping blocks 31 away from each other, thereby making it difficult for the welding wire to contact the damping rubber pad 35.

[0036] When the work is finished and the welding wire between the welding wire turntable 1 and the welding equipment needs to be rewound on the welding wire turntable 1, the threaded column 25 is rotated to make the conical head 26 completely disengaged from the wire slot 34. At this time, the two clamping blocks 31 will approach each other under the action of the two driving springs 32, and then clamp the welding wire. The damping rubber pad 35 will also be pressed against the welding wire to provide a clamping damping force for the welding wire, so that the welding wire between the clamping block 31 and the welding wire turntable 1 is in a straight state. At this time, only one staff member is needed to reversely rotate the welding wire turntable 1.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
