[0014] 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.

[0015] The figure marks in the drawings of the specification include: upper die base 1, upper pad 2, upper clamping plate 3, lower template 4, lower pad 5, lower die base 6, lower pad 7, punch 8, cylinder 9, force transmission rod 10, positioning sleeve 11, punching core groove 12, positioning seat 13, fixing sleeve 14.

[0016] Implementation example Figure 1 and Figure 2 As shown:

[0017] A collector punching die, comprising an upper die base, a lower die base, a lower pad, an upper pad plate and an upper clamping plate arranged on the upper die base, a plurality of punches clamped and fixed by the upper clamping plate, a lower pad plate and a lower die plate arranged on the lower die base, and a plurality of punching core grooves for placing collectors, the number and position of which correspond to the punches one by one, opened on the lower die plate;

[0018] Specifically: the upper die seat, the lower die seat, the lower pad, the upper pad set on the upper die seat, the upper clamping plate, and the plurality of punches clamped and fixed by the upper clamping plate are the established designs of the stamping die. Punching is achieved by using the punch. In order to achieve multi-hole punching, the punch should be designed as a continuous punch. Then, based on the design position of the punch, a punching core groove is designed on the lower die seat, and the punching core groove is used to place the collector.

[0019] Due to the design of the punching core groove, the left and right movement of the header can be limited. However, in the stamping process, the front and back movement of the header needs to be considered. In order to ensure the accuracy and precision of the punching, the front fixing component and the rear fixing component are designed.

[0020] Specific:

[0021] The two ends of the collecting pipe are respectively provided with a front fixing assembly and a rear fixing assembly, and the front fixing assembly can be used to push the collecting pipe out of the punching core groove.

[0022] like Figure 2 As shown, the rear fixing component: the rear fixing component is detachably connected to the lower die base, the rear fixing component is a fixing sleeve, the fixing sleeve is provided with a slot, one end of the manifold is inserted into the slot, the fixing sleeve is a detachable fixing sleeve, when the upper end of the manifold is fixed, the fixing sleeve is used to fix the lower end of the manifold, when the manifold needs to be taken out, only the fixing sleeve needs to be removed;

[0023] At this time, as can be seen from the above, the left and right movement of the header can be limited due to the design of the punching core groove. Although this design can limit the left and right movement of the header, it will make it inconvenient to remove the header. Therefore, the mold is designed with a front fixing component, which is not only used to fix the upper end of the header, but also used to push out and remove the header.

[0024] The front fixing assembly includes a cylinder, a force transmission rod, a positioning seat and a positioning sleeve. The cylinder is installed on one side of the lower mold seat, the protruding end of the cylinder is connected to the force transmission rod, the force output end of the force transmission rod is connected to the positioning seat, the positioning sleeve is installed on the positioning seat, and the other end of the collecting pipe is inserted into the positioning sleeve.

[0025] Specifically: the manifold is fixed by using a positioning sleeve and a fixing sleeve. After the punching of the manifold is completed, the fixing sleeve is removed, and then the cylinder is started. The cylinder drives the force transmission rod to move. After the force transmission rod moves, the positioning seat and the positioning sleeve move, and the manifold is pushed out toward the lower end, so that it is convenient to manually remove the punched manifold.

[0026] The device solves the problem that the traditional manual drilling of the collecting pipe has burrs and serious insufficient production capacity.

[0027] 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.
