[0021] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0022] The embodiment of the present application discloses a mold for making a round tube.

[0023] Reference Figure 1-Figure 3 A mold for making a round tube comprises a first mold block 1, a second mold block 2 and a third mold block 3, wherein the first mold block 1, the second mold block 2 and the third mold block 3 are all in the shape of long strips; a limiting groove 4 adapted to the outer wall of the round tube is opened at the top of the first mold block 1 along its length direction, and a shape of the bottom end of the second mold block 2 is adapted to the inner wall of the round tube; a cylindrical core 5 is arranged between the first mold block 1 and the third mold block 3, and the outer wall of the cylindrical core 5 is adapted to the inner wall of the round tube, and a positioning groove 6 adapted to the outer wall of the round tube is opened along its length direction.

[0024] The operator places the sheet on the first mold block 1, and then places the second mold block 2 on the sheet and presses the sheet downward. The first mold block 1 and the second mold block 2 cooperate to press the sheet, so that the sheet is pressed into the limiting groove 4, and the flat sheet is pressed into a "U" shape. At this time, the "U"-shaped sheet is placed on the first mold block 1, and the operator places the cylindrical core 5 on the sheet, and then places the third mold block 3 on the sheet, and operates the third mold block 3 to press the sheet downward until the outer wall of the sheet fits with the limiting groove 4 and the positioning groove 6, thereby obtaining a cylindrical round tube, and finally taking the cylindrical core 5 out of the round tube to complete the convenient manufacturing process of the round tube.

[0025] The top width of the second mold block 2 is greater than the bottom width of the second mold block 2. When the operator presses the second mold block 2, the operator contacts the wider end of the second mold block 2, which makes it easier for the operator to apply pressure and makes the operation process more convenient.

[0026] The bottom end of the second mold block 2 is provided with a receiving area 8, and the receiving area 8 is used to receive a "U"-shaped plate. When the second mold block 2 applies force to press the flat plate into a "U" shape, the "U"-shaped plate can be gradually bent and placed in the receiving area 8, and the receiving area 8 limits the plate so that the plate can be well bent into a desired shape.

[0027] The first mold block 1 is provided with a cut corner 7, and the cut corner 7 is respectively located on both sides of the limiting groove 4. The angle of the cut corner 7 is 30-60 degrees. The outer wall of the first mold block 1 where the cut corner 7 is located is adapted to the outer wall of the third mold block 3. When the first mold block 1 and the third mold block 3 cooperate to make a round tube, the cut corner 7 can increase the contact area between the limiting groove 4 and the outer wall of the plate, so that the first mold block 1 supports the plate more stably. At the same time, during the pressing process, the outer wall of the third mold block 3 can converge the two sides of the plate, which is conducive to improving the stability during the production of the round tube.

[0028] Positioning plates 9 for positioning the sheet are provided on both sides of the first mold block 1. The positioning plates 9 are connected to the first mold block 1 by bolts 10. When the sheet is processed, the positioning plates 9 fit the outer edge of the sheet, and the positioning plates 9 limit the sheet so that the sheet is not easily offset relative to the first mold block 1. At the same time, the bolts 10 realize the detachable connection between the positioning plates 9 and the first mold block 1, which is convenient for operators to disassemble and replace the positioning plates 9.

[0029] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
