[0002] like Figure 1 The figure shows a manifold, which needs to have rows of connection holes punched on its side wall for connecting flat capillaries. When punching the connection holes, the manifold is easily deformed, resulting in product scrapping. Therefore, before punching, a support rod is inserted into its interior, and the support rod is processed into an avoidance zone facing the connection hole, which can effectively prevent the manifold from deforming during processing. However, after punching the manifold, it is difficult for the manifold to detach from the lower mold. If it is manually pried open with force, there is a great safety hazard.

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 2 As shown, a device for punching connection holes on a manifold for convenient material cutting in this embodiment comprises a workbench 1 and a punching mechanism 2. The punching mechanism 2 is arranged on the workbench 1 and is used for punching connection holes on the manifold.

[0031] The device for punching connecting holes of a manifold for convenient material removal in this embodiment also includes a positioning mechanism and an ejection mechanism.

[0032] The positioning mechanism is arranged on the workbench 1 and faces the discharge end of the punching mechanism 2 .

[0033] Specifically, in this embodiment, Figure 4 As shown, the positioning mechanism includes a pair of positioning seats 3 and a slide block 4; the pair of positioning seats 3 are fixed on the workbench 1 and are distributed on both sides of the discharge end of the punching mechanism 2; a slide groove is horizontally arranged in any of the positioning seats, and the slide groove runs through both ends of the positioning seat and is perpendicular to the discharge direction of the punching mechanism 2. Before punching the connecting hole of the manifold, the support rod is sleeved on the manifold and placed on the lower die seat of the punching mechanism 2, and then the slide block 4 is slid to make it against the handle of the support rod, which can effectively prevent the manifold from moving during punching.

[0034] Furthermore, a limiting long groove 5 is horizontally provided on the outer side of the positioning seat with the slide groove, and the limiting long groove 5 is connected to the slide groove; a toggle rod 6 is horizontally fixed on the side of the slider 4 facing the limiting long groove 5, and the toggle rod 6 passes through the limiting long groove 5; such a configuration can facilitate the operator to adjust the position of the slider in the slide groove through the toggle rod 6, so as to facilitate the positioning of the support rod.

[0035] The ejection mechanism includes a vertical plate 7, a connecting rod 8 and a cylinder 9. The vertical plate 7 is vertically fixed on the workbench 1 and is located on the outside of any positioning seat; the middle part of the connecting rod 8 is hinged on the vertical plate 7, and the connecting rod 8 always remains horizontal. One end of the connecting rod 8 faces the outer baffle of the support rod, and the other end of the connecting rod 8 is connected to the piston rod of the cylinder 9. With such an arrangement, after the manifold completes the punching of the connecting hole, the cylinder 9 is started, so that the connecting rod 8 rotates around the hinge with the vertical plate 7, and finally the other end of the connecting rod 8 pushes the outer baffle of the support rod to eject the support rod with the manifold sleeved thereon.

[0036] In this embodiment, if Figure 3As shown, the cylinder 9 is fixed on the workbench 1, and the piston rod of the cylinder 9 is horizontally arranged and vertically passes through the vertical plate 7; a long groove 10 is provided on the end of the connecting rod 8 connected to the cylinder 9, and the long groove 10 passes through the upper and lower surfaces of the connecting rod 8; a connecting rod 11 is provided at the end of the piston rod of the cylinder 9, and the connecting rod 11 is slidably inserted in the long groove 10; such an arrangement avoids the cylinder 9 being hingedly arranged on the workbench 1 and interfering with other components.

[0037] like Figure 5 As shown, after the punching connection hole of the collecting pipe is completed, the slider 4 is slid by toggling the rod 11, so that the slider 4 moves into the slide groove, driving the cylinder 9. The connecting rod 8 is driven by the cylinder 9 to rotate around the hinge with the vertical plate 7, and finally the other end of the connecting rod 8 pushes the outer baffle 13 of the support rod 12 to eject the support rod with the collecting pipe.

[0038] In this embodiment, a rubber protrusion 14 is provided on one end of the connecting rod 8 facing the outer baffle plate 13 of the supporting rod 12 to avoid rigid contact with the outer baffle plate 13 on the supporting rod 12 .

[0039] 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.
