[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] The figure marks in the drawings of the specification include: upper die base 1, upper pad 2, upper clamping plate 3, upper stripping plate 4, lower template 5, lower die base 6, lower pad 7, limit column 8, side hanging plate 9, flat tube groove blade 10, core rod pad 11, core rod seat 12, auxiliary positioning sleeve 13, positioning seat 14, clamping block 15, core rod assembly 16, cylinder 17, auxiliary removal mechanism 18, inclined surface 19.

[0022] Implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown:

[0023] A mold for punching a straight section of a flat tube groove of a collecting pipe comprises an upper mold base 1 and a lower mold base 6, an upper pad 2, an upper clamping plate 3, and an upper stripping plate 4 arranged on the upper mold base 1, a lower mold plate 5, a flat tube groove blade 10 arranged on the lower mold base 6, and a limiting column 8 arranged between the upper mold base 1 and the lower mold base 6, the upper clamping plate 3 and the upper stripping plate 4 are used to clamp the flat tube groove blade 10, the lower mold base 6 is provided with a mold positioning groove, the mold positioning groove is used to place the collecting pipe, the bottom of the lower mold base 6 is provided with a lower pad 7, and the upper clamping plate 3 and the upper stripping plate 4 are provided with side hanging plates 9 on both sides.

[0024] The above is the conventional design of the mold. The core improvement of this case is:

[0025] The contact surface between the flat tube slot blade 10 and the header is a sloped surface 19;

[0026] Specific: such as Figure 1 and Figure 2 As shown, the collecting pipe is produced by punching a flat tube groove die. The punched product has fewer straight sections at the R position at both ends of the flat tube groove. When welded with the flat tube, there is a phenomenon of loose welding and water leakage. Based on this phenomenon, the inclination of both ends of the flat tube groove blade 10 is changed. The straight sections at the R position at both ends of the punched flat tube groove are much longer than before. After verification, it meets customer requirements.

[0027] The slope is adjusted because the size of the collecting pipe is not fixed. Therefore, pre-production is required before each production.

[0028] It also includes a core rod assembly 16 connected to the manifold and an auxiliary removal structure for moving the core rod assembly 16 .

[0029] Specifically: when the collecting pipe is placed in the positioning groove of the mold, although the left and right movement is restricted, it can move forward and backward. In order to solve this problem, this case is designed to also include a fixing component for fixing the position of the collecting pipe, and the fixing component includes a front end fixation and a rear end fixation. The front end fixation includes a positioning seat 14 and a block 15, and the rear end fixation includes a core rod seat 12, a core rod pad 11 arranged in the core rod seat 12, and an auxiliary positioning sleeve 13 for assisting the position of the collecting pipe.

[0030] Specific: such as Figure 4 As shown, the core rod assembly 16 is used in conjunction with the rear end fixation. The core rod assembly 16 is a long rod structure. One end of the collecting tube is fixed by the rear end fixation, and one end of the collecting tube is fixed by the core rod assembly 16.

[0031] Specifically: the manifold is inserted into the auxiliary positioning sleeve 13 until the core rod seat 12 contacts the core rod pad 11, the manifold is connected by the core rod assembly 16, and then the clamping block 15 is installed on the positioning seat 14, and then the clamping block 15 is fixed with the connecting screws to fix the entire manifold, thereby completing the stamping.

[0032] like Figure 4 As shown, the auxiliary pick-up structure includes a cylinder 17 arranged on one side of the lower die base 6, a cylinder 17 mounting seat and an auxiliary pick-up mechanism 18 connected to the extended end of the cylinder 17, and the auxiliary pick-up mechanism 18 drives the core rod assembly 16 to pull out the manifold.

[0033] Regarding the auxiliary picking mechanism 18: The auxiliary picking mechanism 18 is a rocker arm assembly. When the cylinder 17 drives one end of the rocker arm assembly to move up or down, it will drive the other end of the rocker arm assembly to move down or up. Since the auxiliary picking mechanism 18 is connected to the core rod assembly 16, the core rod assembly 16 can be moved up or down.

[0034] Specific implementation process:

[0035] The upper die base 1 and the lower die base 6 are fixed on the slide and the table of the press machine by pressing plates respectively. Put the product in the mold positioning groove, first put the manifold into the core rod assembly 16, then put the manifold on the outside of the core rod assembly 16 and the core rod pad 11, lock the clamp block 15 to fix the position of the manifold, after the upper and lower molds are closed to punch out the flat tube groove, release the clamp block 15, pull out the manifold under the action of the cylinder 17 and the auxiliary take-out mechanism 18, and finally remove the manifold manually.

[0036] The device solves the problem that the traditional mold has too few straight line segments at the R position at both ends of the flat tube groove.

[0037] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
