[0034] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0035] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0036] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0037] In the related art, when gas-electric vertical welding is used for welding, a water-cooled slider is used on the front side of the weld, and a water-cooled stopper (or pad) is used on the back side of the weld. The flux-cored welding wire is fed into the groove formed by the weldment and the stopper, and the molten pool is constrained on all four sides to achieve single-sided welding and double-sided forming in one go.

[0038] The water-cooled slider is driven by a motor and rises synchronously with the molten pool. At the same time, in order to ensure that the metal liquid in the molten pool does not flow out, a certain pressure needs to be applied to the water-cooled slider, which will cause hard friction between the contact part of the water-cooled slider and the steel plate. When the wear reaches a certain level, there is a risk of internal cooling water leakage, causing welding accidents. Therefore, the entire water-cooled slider needs to be replaced, which causes a certain amount of waste.

[0039] The present application provides a water-cooled slider of gas-electric vertical welding equipment, which improves the structure of the water-cooled slider, and designs the part that is prone to severe wear into a friction rod and separates it from the main body, that is, it is constructed in a combined design of the slider body and the friction rod. The friction rod of the water-cooled slider can be replaced separately after severe wear, which reduces the replacement frequency of the entire water-cooled slider and effectively reduces the cost of use.

[0040] It should be noted that the water-cooled slider described in the following embodiments of the present application, in addition to being used as a water-cooled slider after water is passed into the interior, other heat exchange media can also be passed into the interior to achieve cooling of the welding position.

[0041] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and implementation methods can be combined with each other if there is no conflict.

[0042] In an exemplary embodiment of the utility model, a water-cooled slider of a gas-electric vertical welding device is provided, such as Figure 1 As shown, Figure 1 1 is a front view of a water-cooled slider according to an exemplary embodiment. The water-cooled slider comprises: a slider body 1 and a friction rod 2.

[0043] The slider body 1 is used to move along the corresponding welding track during the material welding process to cool and shape the material welding position, wherein the first outer side surface of the slider body 1 (corresponding to Figure 1The side shown in the figure is bent around the vertical direction to form a cooling shaping groove, and the left and right groove top edges of the cooling shaping groove are respectively provided with friction rod mounting grooves. The friction rod 2 is detachably arranged in the friction rod mounting groove, and a part of the friction rod 2 protrudes from the groove top edge of the cooling shaping groove. In the process of welding the material, the water-cooled slider is in sliding contact with the welded material through the part of the friction rod 2 protruding from the groove top edge.

[0044] In this exemplary embodiment, the structure of the water-cooled slider is improved, and its severely worn part is designed as a friction rod 2 and is separated from the main body, that is, it is configured as a combination design of the slider body 1 and the friction rod 2. The friction rod 2 of the water-cooled slider can be replaced separately after it is severely worn, reducing the replacement frequency of the entire water-cooled slider and effectively reducing the use cost.

[0045] In some exemplary embodiments, Figure 1-Figure 4 As shown, in order to realize that the heat exchange medium inside the water-cooled slider can be circulated or transported in one direction to ensure the cooling of the material welding point, a water-cooling cavity 12 can be set inside the slider body 1 and equipped with corresponding inlets and outlets. Exemplarily, a water-cooling cavity 12 is set inside the slider body 1, and the second outer side surface of the slider body 1 opposite to the first outer side surface (corresponding to Figure 2 A liquid inlet 121 and a liquid outlet 122 are provided on one side (shown in FIG. 1 ), wherein the liquid inlet 121 and the liquid outlet 122 are communicated with the water cooling chamber 12 respectively.

[0046] In this embodiment, by arranging the liquid inlet 121 and the liquid outlet 122 on the same side and connecting the corresponding pipelines on the second outer side, there will be no interference between the liquid inlet and outlet pipelines and other components of the equipment. On the one hand, it is convenient to control the drive of the water-cooled slider, and on the other hand, it can also achieve an overall aesthetic effect.

[0047] In some exemplary embodiments, Figure 1-Figure 4 As shown, in order to ensure good contact between the electrode of the welding mechanism and the material to be welded during welding and prevent overheating and damage, a protective atmosphere can be formed in the welding area by delivering a shielding gas to the welding area, thereby reducing the influence of oxygen on welding, preventing oxidation and pollution, and improving welding quality and efficiency. Exemplarily, the slider body 1 is provided with a shielding gas channel 11 running through the body thereof, wherein the shielding gas channel 11 is used to deliver shielding gas, and one end of the shielding gas channel 11 extends to the first outer side surface and forms a shielding gas outlet 112, and the other end of the shielding gas channel 11 extends to the second outer side surface and forms a shielding gas inlet 111.

[0048] In this embodiment, considering that the slider body 1 needs to be provided with a shielding gas channel 11 and a water cooling chamber 12, the shielding gas channel 11 should not be made too large, so as to reserve sufficient space for the water cooling chamber 12. However, in order to facilitate comprehensive protection of the welding area, the shape of the shielding gas outlet 112 can be optimized. Exemplarily, the shielding gas outlet 112 adopts a trumpet-shaped structure that gradually expands along the shielding gas delivery direction. Optionally, the trumpet-shaped structure can be a square gradually expanding mouth, or a duckbill-shaped gradually expanding mouth.

[0049] It should be noted that the size of the shielding gas outlet 112 can be designed according to the range of the welding area, and it is only necessary to ensure that the shielding gas outputted can cover the entire welding area.

[0050] In some exemplary embodiments, Figure 1-Figure 4 As shown, when the gas-electric vertical welding equipment welds materials, the water-cooled slider will be controlled to move from bottom to top. At this time, the water-cooling chamber 12 can be designed at the lower part of the slider body 1, and the shielding gas channel 11 can be designed at the upper part of the slider body 1. Correspondingly, the shielding gas outlet 112 is also located at the upper part of the first outer side surface.

[0051] During the welding process, the welding area will be covered by the output shielding gas to form protection. Since the water-cooling chamber 12 corresponds to the cooling and shaping groove, the corresponding welding area can be gradually cooled and shaped as the water-cooling slider moves.

[0052] In some exemplary embodiments, Figure 1-Figure 4 As shown, since the water-cooled slider moves from bottom to top, friction rods 2 can be installed on both vertical edges of the first outer side surface, thereby forming an overall protection for the slider body 1. Exemplarily, the friction rod installation groove is opened along the vertical direction at the groove top edge of the corresponding cooling shaping groove.

[0053] Optionally, the friction rod 2 adopts a columnar structure, and the friction rod 2 includes: a friction section 21 and a limiting section 22, wherein the friction section 21 adopts a circular columnar structure; the limiting section 22 adopts a columnar structure with a non-circular cross section, the limiting section 22 is arranged at one end of the friction rod 2 and is coaxial with the friction section 21, and the orthographic projection of the cross section of the limiting section 22 is located within the cross section of the friction section 21. Accordingly, the friction rod installation groove extends from the upper part of the groove top edge of the cooling and shaping groove to the lower part, wherein the first groove portion of the friction rod installation groove corresponding to the friction section 21 covers part of the outer peripheral wall of the friction section 21; the second groove portion of the friction rod installation groove corresponding to the limiting section 22 at least covers most of the outer peripheral wall of the limiting section 22.

[0054] The structure of the limiting section 22 can be designed as a regular polygonal columnar structure or other limiting structures that can limit the rotation of the friction rod 2 in the friction rod installation groove. For example, when the limiting section 22 adopts a square columnar structure, the second groove portion at least covers three edges of the limiting section 22; when the limiting section 22 adopts a triangular columnar structure, the second groove portion at least covers two edges of the limiting section 22. When the limiting section 22 is designed as a regular polygonal columnar structure, if the friction section 21 corresponding to an edge or a side of the limiting section 22 is worn, so that the friction rod 2 cannot protect the first outer side surface of the slider body 1, the corresponding angle between the friction rod 2 and the friction rod installation groove can be adjusted, so that the friction rod 2 can continue to be used, further reducing the number of replacement times of the friction rod 2, and further reducing the comprehensive cost of the water-cooled slider.

[0055] The exemplary embodiment of the utility model also provides a gas-electric vertical welding device, which includes: a welding mechanism for welding materials; a driving mechanism, on which a water-cooled slider in any of the above embodiments is arranged, which is used to drive the water-cooled slider to move along the corresponding welding track during the welding process of the materials, wherein the driving arm of the driving mechanism is connected to the connecting portion 13 arranged on the second outer side of the slider body 1, and the connecting portion 13 can be designed as a cross-shaped structure, so that the two can be connected more stably, such as Figure 2 and a water cooling system, which is connected to the water cooling chamber 12 of the water cooling slider and is used to cooperate with the water cooling slider to cool and shape the material welding position.

[0056] Specifically, the water-cooled slider is used in the welding of steel plates with large-line energy gas-electric vertical welding during use. It is placed on the front of the weld and forms a quadrilateral structure with the groove of the steel plate and the lining plate on the back of the weld. Based on the hollow three-dimensional structure of the water-cooled slider body, two circular openings are set at the lower part of its second outer side surface for the entry and exit of the coolant; a shielding gas channel 11 is set at its upper part, and a shielding gas inlet 111 for receiving the shielding gas is set at the upper part of the second outer side surface, and a trumpet-shaped shielding gas outlet 112 is formed at the upper part of the first outer side surface, so that the trumpet opening direction is the direction of contact with the steel plate. The first outer side surface of the water-cooled slider contacts the material (such as the steel plate), and the first outer side surface is a cooling shaping groove (a shape with protruding sides and a concave middle) to meet the weld excess height requirements. The friction rod mounting groove at the top edge of the groove (the protruding parts on both sides) is a C-shaped structure, and the opening size of the C-shaped structure must be smaller than the maximum diameter of the C-shaped structure, wherein the lower end of the C-shaped structure set by the slider body 1 is a "coin-shaped" structure, that is, an inner square and outer circle structure. The upper end of the friction rod 2 is designed to be cylindrical. Based on the C-shaped opening design, the friction section 21 of the friction rod 2 can protrude from the C-shaped opening of the slider body 1. The lower end is a rectangular parallelepiped or a cube. The interface size is just consistent with the rectangular parallelepiped or square opening in the C-shaped structure at the lower end of the water-cooled slider body. After plugging and assembling, the direction of the friction rod 2 can be fixed to prevent it from rotating at will. By separating the existing gas-electric vertical welding water-cooled slider into a slider body 1 and a friction rod 2, the consumption of the water-cooled slider body with a high cost can be effectively reduced; by matching the lower end of the friction rod 2 with the square at the lower end of the C-shaped structure of the slider body 1, the friction rod 2 can be reused after a 90° rotation, that is, one friction rod 2 can be used in four positions, which reduces the loss again.

[0057] A usage scenario of the gas-electric vertical welding equipment in this embodiment is described below.

[0058] Step 1, when performing gas-electric vertical welding, assemble the friction rod 2 through the friction rod mounting groove of the water-cooled slider, and fix the relative position of the friction rod 2 and the slider body 1 unchanged.

[0059] Step 2, then connect the slider body 1 installed with the friction rod 2 to the cooling water and protective gas, and press the water-cooled slider onto the welding groove of the material through the driving mechanism (including pressure sensing and driving motor). After welding starts, push the water-cooled slider to move upward as a whole.

[0060] Step 3. After the water-cooled slider has been used for a period of time, if the friction rod 2 is severely worn, that is, the height of the friction rod 2 protruding from the friction rod mounting slot can no longer effectively isolate the slider body 1 and the welded steel plate, the friction rod 2 needs to be pulled out of the friction rod mounting slot, and the orientation needs to be adjusted (for example, when the limiting section 22 of the friction rod 2 is a square columnar structure, it needs to be rotated 90° each time) and then installed and used again, so that each friction rod 2 can be used in multiple directions.

[0061] When the friction rod 2 is worn out in multiple directions to the point where it cannot effectively isolate the water-cooled slider body and the welding steel plate, replace it with a new friction rod 2 and repeat steps 1-3.

[0062] In this embodiment, the gas-electric vertical welding water-cooled slider is designed to be split, and a separate design is made for the part that is severely worn due to hard friction with the welding steel plate, effectively reducing the waste caused by the need to replace the entire part due to severe wear. At the same time, a directional slot design is performed to maximize the use of the friction rod 2 component for multiple times, further reducing consumption.
