[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example: A gradient roll cooling device for irregularly shaped welded pipe molds, such as... Figures 1-5 As shown, it includes a welding pipe device main unit 11 and a roller patterning mold 1 rotatably mounted on its upper surface via a support shaft. Several baffles 5 are fixedly installed on the upper surface of the roller patterning mold 1, and an overflow groove 10 is opened on the upper surface of the roller patterning mold 1.

[0031] Several coolant pipes 2 are fixedly installed on the upper surface of the main unit 11 of the pipe welding device, and a swing pipe 4 is fixedly installed on one end of the coolant pipe 2.

[0032] Coolant pipe 2 has a built-in actuating fan blade 6;

[0033] A contact block 8 is fixedly installed on the inner wall surface of the swing tube 4.

[0034] The contact block 8 is made of wear-resistant and non-plastic material, and the swing pipe 4 is made of material with high plasticity and fatigue resistance.

[0035] When the roller pattern mold 1 is cooled, the cooling liquid first flows at high speed in the cooling liquid pipe 2, and at the same time, the cooling liquid contacts the driving fan blade 6, which is pushed by the cooling liquid. When the driving fan blade 6 rotates to the contact block 8, the driving fan blade 6 extrudes the contact block 8, and at the same time, the contact block 8 pushes the swing pipe 4 to deform. At this time, the swing pipe 4 can drive the liquid outlet to swing up and down or left and right, and the cooling liquid is uniformly sprayed on the pipe mold. At the same time, when the cooling liquid is sprayed on the upper surface of the roller pattern mold 1, the cooling liquid is limited on the upper surface of the roller pattern mold 1 by the baffle 5, thereby preliminarily cooling the roller pattern mold 1. At the same time, the rotation of the rotating roller pattern mold 1 guides the cooling liquid to the inside of the overflow groove 10 by the principle of centrifugal force. When the overflow groove 10 is filled with cooling liquid, the cooling liquid flows down along the surface of the roller pattern mold 1, thereby uniformly cooling the surface of the roller pattern mold 1. By arranging the driving fan blade 6, the contact block 8 can be pushed to make the swing pipe 4 swing regularly, thereby uniformly spraying the cooling liquid on the roller pattern mold 1, thereby achieving the effect of uniform cooling. At the same time, the rotating driving fan blade 6 can reduce the flow rate of the cooling liquid in the cooling liquid pipe 2, thereby avoiding the splashing of the cooling liquid on the roller pattern mold 1 caused by high-speed ejection, thereby achieving the effect of preventing the splashing of the cooling liquid. By arranging the baffle 5, the cooling liquid can be retained on the upper surface of the roller pattern mold 1, thereby slowing down the flow rate of the cooling liquid on the upper surface and ensuring the cooling effect of the upper surface of the roller pattern mold 1, thereby achieving the effect of uniform cooling. The baffle 5 can block the cooling liquid to prevent the cooling liquid from being thrown by centrifugal force, thereby achieving the effect of good cooling. By arranging the overflow groove 10, the cooling liquid can be stored, so that the cooling liquid flowing out of the baffle 5 flows into the inside, thereby avoiding the direct throwing of the cooling liquid. At the same time, when the cooling liquid fills the overflow groove 10, the edge of the overflow groove 10 can guide the cooling liquid by centrifugal force, and the cooling liquid flows down along the surface of the roller pattern mold 1 by the liquid film adhesion ability, thereby achieving the effect of uniform cooling.

[0036] As shown in Figures 1-5 The driving fan blade 6 is symmetrical and has a guide groove 9 on one side of the driving fan blade 6, and the top end of the driving fan blade 6 is arc-shaped.

[0037] The guide groove 9 is V-shaped and inclined at an angle of two degrees.

[0038] The top end surface of the driving fan blade 6 is made of wear-resistant material.

[0039] Two of the two toggle leaves 6 can ensure the stability of rotation, while too few toggle leaves 6 reduce the cooling liquid flow rate and have poor effect, and too many toggle leaves 6 will excessively reduce the cooling liquid flow rate, resulting in poor cooling effect, therefore, two toggle leaves 6 can better achieve the effect of reducing the cooling liquid flow rate, and the flow guide groove 9 can guide a part of the cooling liquid, when the flow guide groove 9 rotates to contact the block 8, at this time, the space here is in the smallest state, the cooling liquid will press the contact block 8, thereby further increasing the swing amplitude of the swing pipe 4, and the circular arc-shaped toggle leaf 6 at the top can more smoothly slide from the surface of the contact block 8, thereby avoiding the phenomenon of jamming, resulting in uneven cooling, and the shape of the flow guide groove 9 can accelerate the flow of the cooling liquid, thereby being able to push the contact block 8, and the certain angle of inclination can ensure the flow rate range of the cooling liquid, thereby avoiding the situation that the cooling liquid flow rate occasionally decreases to cause the contact block 8 unable to be pushed, and the flow direction of the cooling liquid can be guided.

[0040] As shown in Figures 1-5 , the contact block 8 is in a semicircular shape, and the contact block 8 is perpendicular to the toggle leaf 6.

[0041] The surface of the contact block 8 is made of wear-resistant material.

[0042] The semicircular contact block 8 can reduce the local pressure of movement, avoid excessive swing of the swing pipe 4 caused by excessive pressure, and ensure smooth sliding of the toggle leaf 6, so that it will not jam, the contact block 8 in a vertical state and the toggle leaf 6 can ensure the accuracy of contact between the two, and can ensure the swing angle of the swing pipe 4.

[0043] As shown in Figures 1-5 , the height of the baffle 5 is five millimeters, the interval between the baffles 5 is one to two centimeters, and the baffles 5 are in a gradually expanding circular shape.

[0044] The overflow groove 10 is in a ring-shaped closed shape, and the groove depth of the overflow groove 10 is five to one centimeter.

[0045] The height of the baffle 5 can ensure that the cooling liquid will not be thrown out due to centrifugal force, while too low baffle 5 will lose the blocking effect, and too high baffle 5 will make the cooling liquid thrown into its interior less, resulting in uneven distribution of the cooling liquid on the surface of the roller pattern mold 1, and the gradually expanding baffles 5 can maintain the flow space of the cooling liquid on them, ensure the effect of centrifugal force, and make it flow into the overflow groove 10, thereby ensuring the effects of uniform cooling and preventing the cooling liquid from splashing.

[0046] As shown in Figures 1-5As shown, the inner wall surface of the cooling liquid pipe 2 is fixedly installed with a flow limiting plate 7, a flow limiting hole 12 is formed through the middle part of the flow limiting plate 7, and the flow limiting plate 7 is fixedly connected with the push fan blade 6 through a rotating shaft.

[0047] The flow limiting plate 7 can reduce the flow rate of the cooling liquid, the flow limiting hole 12 can ensure the flow of the cooling liquid, and the phenomenon that the cooling liquid pipe 2 is broken due to excessive pressure can be avoided.

[0048] Working principle: when the roller pattern mold 1 is cooled, the cooling liquid pushes the push fan blade 6, the push fan blade 6 rotates, the contact block 8 drives the swing pipe 4 to swing, at this time, part of the cooling liquid falls on the upper surface of the roller pattern mold 1, the baffle 5 blocks and guides the cooling liquid, and the overflow groove 10 guides the cooling liquid, so that uniform cooling and prevention of cooling liquid splashing are ensured.

[0049] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
