[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] A sleeve assembly for stamping a collecting pipe in this embodiment includes an upper sleeve bar 1 and a lower sleeve bar 2 .

[0023] like Figure 2 As shown, the bottom of the upper sleeve strip 1 is a plane, the upper surface of the upper sleeve strip 1 is an arc-shaped surface, and the upper surface of the upper sleeve strip 1 is adapted to the inner wall of the header to be processed.

[0024] A plurality of avoidance grooves 3 are provided on the upper surface of the upper sleeve connecting strip 1 at equal intervals along the length direction of the upper sleeve connecting strip, and the interval between two adjacent avoidance grooves 3 is adapted to the interval between the connection holes on the processed header.

[0025] like Figure 3 As shown, the upper surface of the lower sleeve bar 2 is a plane; the lower surface of the lower sleeve bar 2 is an arcuate surface, and the lower surface of the lower sleeve bar 2 is matched with the inner wall of the collecting pipe.

[0026] When in use, first fix the lower sleeve strip 2 on the lower die base of the stamping device and keep the lower sleeve strip 2 horizontal; sleeve the collecting pipe to be processed on the upper sleeve strip 1, and then insert the lower sleeve strip 2. At this time, the upper surface of the lower sleeve strip 2 fits with the lower surface of the upper sleeve strip 1, and the arc surface of the upper / lower sleeve strip fits with the inner wall of the collecting pipe; the tool on the external stamping device moves downward to perform the stamping operation.

[0027] In this embodiment, if Figure 4 As shown, one end of the lower sleeve strip 2 has a connecting block 9, and the connecting block 9 has a bolt 10. The lower sleeve strip 2 is detachably fixed to the lower mold base through the bolt 10 on the connecting block 9, realizing a detachable connection, which is convenient for maintenance and replacement.

[0028] In this embodiment, if Figure 4 As shown, the socket assembly also includes a handle 4, the handle 4 has a socket part 5, one end of the upper socket strip 1 has an insertion part 6, the upper socket strip 1 is inserted into the socket part 5 on the handle 4 through the insertion part 6, and the handle 4 is also provided with a fastening bolt 7, one end of the fastening bolt 7 extends all the way into the socket part 5; such an arrangement realizes a detachable connection, and the user can hang a suitable upper socket strip according to the collecting pipes of different cross-sectional sizes and install it on the handle, thereby increasing the applicability.

[0029] Furthermore, a stopper 8 is fixed on the outer end of the handle 4. After the punching connection hole of the collecting pipe is completed, the collecting pipe is difficult to be separated from the upper / lower connecting strips. The stopper 8 can be pushed by an external driving device to separate the upper connecting strip 1 from the lower connecting strip 2, making it convenient to remove the collecting pipe.

[0030] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
