Description

Technical Field

[0001] The utility model relates to the technical field of double-wall corrugated pipe processing, in particular to a hole expanding device for double-wall corrugated pipe processing. Background Art

[0002] The cross-section of the double-wall corrugated pipe is a double-layer structure, the inner wall is smooth and flat, and the outer wall is equidistantly arranged with a trapezoidal hollow structure. When expanding the hole of the PVC double-wall corrugated pipe, a hole expansion device is required.

[0003] According to publication number CN213648655U, a reaming device for processing PVC double-wall corrugated pipes is provided. When the reaming device for processing PVC double-wall corrugated pipes is used, the device is connected to an external power supply, and the PVC double-wall corrugated pipe is first placed on a first jacket, and then the second jacket moves downward under the extension of a second electric telescopic column, so as to clamp and fix the PVC double-wall corrugated pipe between the first jacket and the second jacket. Then, the first electric telescopic column and the second electric telescopic column are used in combination, and the PVC double-wall corrugated pipe moves up and down as a whole along with the first jacket and the second jacket until the PVC double-wall corrugated pipe is directly to the left of the reamer. Then, the electric telescopic rod is extended, and the bracket slides to the left under the action of the slide groove, thereby driving the reamer to move to the left and extend into the inner side of the PVC double-wall corrugated pipe. At the same time, the reamer rotates under the action of a motor and a motor shaft, so as to facilitate the reaming process of the PVC double-wall corrugated pipe, and the annular electric heating plate heats the PVC double-wall corrugated pipe, so as to facilitate and better complete the reaming operation.

[0004] The position of the double-walled corrugated pipe can be fixed by the above-mentioned structures such as the first jacket and the second jacket. However, when the double-walled corrugated pipe is expanded, since the length of the double-walled corrugated pipe is generally long, after one end is fixed by the first jacket and the second jacket, the other end moves downward, which can easily cause the fixed end to tilt and incline at a certain angle, thereby affecting the normal expansion of the double-walled corrugated pipe.

[0014] As a further improvement of the above solution, the adjustment plate is located between the second motor and the rotating plate, and the number of the second electric telescopic rods is four, and the four second electric telescopic rods are distributed circumferentially with the connecting column as the center.
