Description

However, manual bending has low production efficiency and relies on the experience of operators, making it difficult to achieve standardization. Moreover, manual bending has poor consistency, resulting in large deviations in the flatness of the water cooling plate bends and difficulty in subsequent shaping. Utility Model Content

[0028] like Figure 1-Figure 3As shown, the water-cooled bent pipe 100 includes a connected bent section 101 and a section to be bent 102 . After the section to be bent 102 is bent, the gap between the section to be bent 102 and the bent section 101 is small.

[0029] In order to bend a water-cooled bent pipe 100 with a small gap, this embodiment provides a wheel mold structure for bending pipes, which is configured to be fixed on a pipe bending device. The wheel mold structure for bending pipes includes a support plate 1 and a strip block 2, the strip block 2 is arc-shaped in the length direction, one end face of the strip block 2 in the width direction is an arc-shaped convex surface 23, and the other end face is an arc-shaped concave surface 24, a first arc-shaped pipe placement groove 25 is provided on the arc-shaped convex surface 23, the first arc-shaped pipe placement groove 25 extends along the length direction of the strip block 2, one end of the first arc-shaped pipe placement groove 25 in the length direction passes through one end of the strip block 2 in the length direction, the support plate 1 is connected to the arc-shaped concave surface 24, in the height direction of the strip block 2, the upper end face of the support plate 1 is not higher than the lower groove edge of the first arc-shaped pipe placement groove 25, and the support plate 1 is configured to be fixed on the pipe bending device.

[0030] During installation, the support plate 1 of the wheel mold structure is fixed on the pipe bending equipment to keep it stationary. When in use, first, the bent section 101 of the water-cooled bent pipe 100 is placed on the side of the arc-shaped concave surface 24 away from the arc-shaped convex surface 23, and placed on the support plate 1, supported by the support plate 1, and then, the section to be bent 102 connected to the bent section 101 is led out from one end of the first arc-shaped pipe placement groove 25 through the strip block 2 to the side of the arc-shaped convex surface 23 away from the arc-shaped concave surface 24, and the pipe bending equipment can be used to bend the section to be bent 102, so that the section to be bent 102 is embedded in the first arc-shaped pipe placement groove 25 to form a certain degree of curvature, and the bending is completed.

[0031] In the wheel mold structure for pipe bending provided in this embodiment, the upper end surface of the support plate 1 is not higher than the lower groove edge of the first arc-shaped pipe placement groove 25. In the process of the section to be bent 102 following the first arc-shaped pipe placement groove 25, there is no spatial interference problem between the bent section 101 and the support plate 1, and the section can be supported by the support plate 1, thereby ensuring the stability of the pipe bending process. As a strip block 2, its narrow and long characteristics are conducive to being suitable for smaller pipe bending gaps at a smaller width size. At the same time, the strip block 2 can meet the bending of a certain length of water-cooled bent pipe 100 at a longer arc length.

[0032] In this embodiment, the strip block 2 includes a first bending section 21 and a second bending section 22 connected along its length direction, one end of the first arc-shaped tube placement groove 25 in the length direction passes through the first bending section 21 away from the end of the second bending section 22, and the other end extends to the second bending section 22, and the curvature of the first bending section 21 is greater than the curvature of the second bending section 22. The larger curvature of the first bending section 21 makes the distance between the bent section 102 and the bent section 101 smaller after bending, meeting the requirement of a small gap.

[0033] In this embodiment, the upper end surface of the support plate 1 and the lower groove edge of the first arc-shaped pipe placement groove 25 are at the same height in the height direction of the strip block 2. Specifically, the water-cooled bent pipe 100 is planar, and the upper end surface of the support plate 1 is a plane. Therefore, when the section to be bent 102 follows the first arc-shaped pipe placement groove 25, the bent section 101 is supported on the support plate 1.

[0034] In this embodiment, a pipe bend avoidance groove 26 is provided on the arc-shaped concave surface 24, and the pipe bend avoidance groove 26 passes through the upper end surface of the strip block 2 in the height direction, and the pipe bend avoidance groove 26 is located above the support plate 1. The pipe bend avoidance groove 26 can further avoid the bent section 101 of the water-cooling elbow 100 to avoid interference.

[0035] In this embodiment, the support plate 1 is provided with a connection hole 11, and the support plate 1 is configured to be fixed to the pipe bending device through the connection hole 11. Specifically, there are two connection holes 11, and bolts pass through the connection holes 11 to fasten the support plate 1 to the pipe bending device.

[0036] In this embodiment, the support plate 1 and the strip block 2 are integrally formed, and the structure has high strength and does not need to be disassembled.

[0037] This embodiment further provides a wheel die assembly for bending a pipe, comprising a clamping member 3 and the wheel die structure for bending a pipe, wherein the clamping member 3 is provided with a clamping concave surface 31 that can conform to the arcuate convex surface 23. Specifically, the clamping concave surface 31 conforms to the first bending section 21, thereby fixing the end of the section to be bent 102 and preventing the section to be bent 102 from deflecting during the bending process.

[0038] In this embodiment, the clamping concave surface 31 is provided with a second arc-shaped tube placement groove 32 opposite to the first arc-shaped tube placement groove 25. That is, the first arc-shaped tube placement groove 25 and the second arc-shaped tube placement groove 32 clamp and limit the end of the section to be bent 102 together, with a high clamping degree and stable limiting of the section to be bent 102.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
