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

[0029] Example 1

[0030] A device for punching row connection holes in a collecting pipe according to the present embodiment includes a supporting mechanism and a punching mechanism.

[0031] like Figure 2 As shown, the supporting mechanism includes a workbench 1 and a positioning plate 2; the positioning plate 2 is fixed on the workbench 1; the front end of the upper surface of the positioning plate 2 extends backward horizontally and is provided with a first groove 3 extending in a straight line, and the cross-section of the first groove 3 is arc-shaped; the workbench 1 is located around the positioning plate 2 and a plurality of positioning columns 4 are vertically and evenly provided.

[0032] In this embodiment, a gap is left between the end of the first groove 3 and the rear end of the positioning plate 2. This arrangement can effectively resist the manifold of the connecting hole to be punched, thereby playing a positioning role.

[0033] like Figure 3 As shown, the stamping mechanism includes a support seat 5, a pressing plate 6 and a plurality of stamping knives 7; a plurality of sleeves 8 are provided on the lower surface of the support seat 5, and the sleeves 8 correspond one-to-one to the positioning columns 4. The support seat 5 is sleeved on the positioning columns 4 of the workbench 1 through the sleeves 8.

[0034] In this embodiment, a first spring 9 is sleeved on the positioning column 4, one end of the first spring 9 contacts the upper surface of the workbench 1, and the other end contacts the lower surface of the sleeve 8; such an arrangement plays a certain buffering role.

[0035] The lower surface of the support seat 5 is located opposite to the first groove 3, and a plurality of punching knives 7 are vertically and evenly spaced along the length direction of the first groove 3; the support seat 5 is connected to an external hydraulic device, and driven by the hydraulic device, the support seat 5 is moved in the vertical direction.

[0036] A plurality of guide posts 10 are vertically fixed to the upper surface of the pressing plate 6, and the guide posts 10 slide through the support seat 5; Figure 4 As shown, a second groove 11 is provided on the lower surface of the pressing plate 6 at a position opposite to the first groove 3, and the cross-section of the second groove 11 is an arc-shaped structure and is adapted to the first groove 3; a guide hole 12 is provided at a position of the pressing plate 6 opposite to each of the punching knives 7, and the guide hole 12 passes through the upper and lower surfaces of the pressing plate 6.

[0037] In this embodiment, a second spring 13 is sleeved on the guide column 10 between the support seat 5 and the pressing plate 6, which can play a certain buffering role when the pressing plate 6 presses down the manifold with the connecting holes to be punched.

[0038] In this embodiment, a plurality of first limiting columns 14 are vertically arranged upward on the workbench 1, and a plurality of second limiting columns 15 are vertically arranged on the lower surface of the support seat 5, and the second limiting columns 15 correspond to the first limiting columns 14 one by one, and the first limiting columns 14 and the corresponding second limiting columns 15 share the same axis. Such an arrangement can effectively limit the descending distance of the stamping mechanism and avoid crushing the manifold.

[0039] When the above-mentioned device for punching the row of connecting holes for the collecting pipe is in operation, the collecting pipe is first placed in the first groove 3 on the positioning plate 2, and one end of the collecting pipe is close to the end of the first groove 3; the external hydraulic device is started, and the support seat 5 descends until the second groove 11 on the pressing plate 6 cooperates with the first groove 3 to press the collecting pipe; the hydraulic device continues to drive the support seat 5 to move downward, and the punching knife 7 moves downward along the guide hole 12 to punch out the connecting holes on the collecting pipe.

[0040] 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.
