[0055] Example

[0056] This embodiment provides a hydraulic extrusion coil copper tube bending device, such as... Figures 2-5 As shown, it includes:

[0057] Press the main body 1;

[0058] Hydraulic drive component 2 is installed on clamping body 1;

[0059] The static mold body 4 is set on the clamping body 1;

[0060] The moving mold body 3 is disposed on the hydraulic drive component 2, and the moving mold body 3 is moved closer to or away from the stationary mold body 4 by the hydraulic drive component 2;

[0061] The working surface of the stationary mold body 4 and the moving mold body 3 is the opposite surface of the moving mold body 3. The working surface of the moving mold body 3 is composed of a first plane 51, a first arc surface 52, a second plane 53, a second arc surface 54, and a third plane 55, which are connected sequentially and smoothly transitioned (with continuously changing slopes). The first plane 51 and the third plane 55 are parallel to the bottom side surface 56, and the second plane 53 forms an angle of 40° to 50° with the bottom side surface 56. The distance from the first plane 51 to the bottom side surface 56 is greater than the distance from the third plane 55 to the bottom side surface 56. The working surface of the stationary mold body 4 corresponds to that of the moving mold body 3.

[0062] In this embodiment, the hydraulic extrusion coil copper tube bending device uses a hydraulic drive 2 to drive the moving mold 3 closer to or further away from the stationary mold 4 to extrude and bend the coil copper tube. The working surface has a structure of three planes and two arc surfaces, causing the processed coil copper tube to form a Z-shaped structure, such as... Figure 6 As shown, after the upper coil 91 and the lower coil 92 are wound, the gap at the joint is fitted together. Figure 6 The coil is less prone to breakdown (at the circle), thus increasing its lifespan.

[0063] Furthermore, the pressing body 1 includes a side plate 10, a bottom plate 11, a first longitudinal plate 12, a second longitudinal plate 13, a third longitudinal plate 14, and a fourth longitudinal plate 15. The first longitudinal plate 12, the second longitudinal plate 13, the third longitudinal plate 14, and the fourth longitudinal plate 15 are parallel to each other, and the first longitudinal plate 12, the second longitudinal plate 13, the third longitudinal plate 14, and the fourth longitudinal plate 15 are all located at the bottom of the bottom plate 11. One end of the first longitudinal plate 12, the second longitudinal plate 13, the third longitudinal plate 14, and the fourth longitudinal plate 15 is connected to the side plate 10. A hydraulic drive component 2 is installed on the side plate 10.

[0064] Furthermore, the first longitudinal plate 12, the second longitudinal plate 13, the third longitudinal plate 14, and the fourth longitudinal plate 15 are all I-beams, with the first longitudinal plate 12 and the second longitudinal plate 13 arranged opposite to each other, and the third longitudinal plate 14 and the fourth longitudinal plate 15 arranged opposite to each other. The use of I-beams can increase the strength of the first longitudinal plate 12, the second longitudinal plate 13, the third longitudinal plate 14, and the fourth longitudinal plate 15 while using relatively little material.

[0065] Furthermore, the base plate 11 is provided with a plurality of mounting holes 111, and the stationary mold body 4 is mounted on the mounting holes 111 by screws.

[0066] Furthermore, the hydraulic drive component 2 includes a cylinder 21, a telescopic rod 22, and a support ear plate 23 disposed at the end of the telescopic rod 22, wherein the support ear plate 23 is connected to the moving mold body 3.

[0067] Furthermore, the supporting ear plate 23 is connected to the moving mold body 3 via a rotating shaft.

[0068] Furthermore, the base plate 11 is provided with two cutouts 110, and the support ear plate 23 is disposed at the cutouts 110, and the position of the support ear plate 23 is restricted by the side wall at the cutouts 110.

[0069] Furthermore, the two openings 110 are located between the first longitudinal plate 12 and the second longitudinal plate 13, and between the third longitudinal plate 14 and the fourth longitudinal plate 15, respectively, to reduce the impact of the openings 110 on the strength of the base plate 11.

The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
