[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Combination Figure 1 and Figure 2As shown, a feeding mechanism for a triangular workpiece punching device includes a worktable 1. A conveyor belt 2 is provided on one side of the worktable 1, and the right end of the conveyor belt 2 extends to the middle of the worktable 1. A first stop bar 3 is provided on the worktable 1 at the right end of the conveyor belt 2. The first stop bar 3 is arranged longitudinally. A first push block 4 and a second push block 5 are respectively provided on the worktable 1 on the left and right sides of the front end of the first stop bar 3. The first push block 4 and the second push block 5 are respectively movably connected to the worktable 1. The first push block 4 is arranged corresponding to the right end of the conveyor belt. A third push block 5 is movably connected to the worktable 1 on the rear side of the conveyor belt 2. Push block 6, the workbench 1 to the right of the third push block 6 is provided with a punching seat 7, the workbench 1 in front of the punching seat 7 is provided with a discharge port 13, the workbench 1 to the right of the punching seat 7 is provided with a second stop bar 8, the second stop bar 8 is arranged longitudinally, the second push block 5 is arranged between the first stop bar 3 and the second stop bar 8, the workbench 1 is also provided with a third stop bar 9 arranged laterally, the third stop bar 9 is located behind the conveyor belt 2 and is arranged to avoid the third push block 6, the third stop bar 9 and the second stop bar 8 are kept apart, the workbench 1 behind the punching seat 7 is also connected to a fourth push block 10 that moves back and forth.

[0018] The working principle of the above structure is as follows: Triangular workpieces are placed sequentially on conveyor belt 2 and fed to workbench 1 on the right. The rightmost triangular workpiece is named the first workpiece 11, and the workpiece behind it is named the second workpiece 12. The first workpiece 11 is first stopped by the first stop bar 3. Then, the first push block 4 moves backward, pushing the first workpiece 11 until it abuts the third stop bar 9. At this point, before the first push block 4 retracts, the second workpiece 12 is stopped by the first push block 4 and cannot continue to move to the right. Then, the third push block 6 pushes the first workpiece 11 to the right until it enters the punching seat 7 and abuts the second stop bar 8 before retracting. After that, the second push block 5 moves backward, causing the first workpiece 11 to abut the fourth push block 10, so that the first workpiece 11 is accurately positioned on the punching seat 7. The drilling mechanism then lowers to drill the first workpiece 11. While the first workpiece 11 is being drilled, the second workpiece 12 is pushed and abuts the third stop bar 9. After the first workpiece 11 is drilled, The fourth pusher 10 moves forward, pushes the first workpiece 11 into the discharge port 13 and resets it. The above action is repeated to send the second workpiece 12 to the punching hole, and this cycle continues.

[0019] The advantages of the above structure are: it is simple to construct, can realize the automated and orderly feeding and unloading of workpieces, and can accurately push the workpieces onto the punching seat, which is conducive to realizing fully automated punching of workpieces.

[0020] In another embodiment, combined Figure 1 and Figure 2As shown, a baffle 14 is provided on each side of the conveyor belt 2. The right ends of the two baffles 14 and the first baffle 3 maintain a distance corresponding to the width of the first push block 4 to ensure that the workpiece will not be deviated on the conveyor belt 2 and to avoid the displacement of the first push block 4.

[0021] In another embodiment, combined Figure 1 and Figure 2 As shown, the third stop bar 9 and the second stop bar 8 maintain a spacing corresponding to the length of the workpiece.

[0022] In another embodiment, combined Figure 1 and Figure 2 As shown, the length of the first push block 4 is greater than or equal to twice the width of the workpiece, so as to ensure that the first push block 4 can maintain the limit on the second workpiece 12 when pushing the first workpiece 11.

[0023] In another embodiment, combined Figure 1 and Figure 2 As shown, a cover 15 is also provided above the right end of the two baffles 14. This part is the position where the conveyor belt 2 and the first push block 4 meet the workpiece. Since the conveyor belt 2 always maintains the trend of conveying to the right, there is a risk that the workpiece will be pushed and bounced up due to positional displacement during the handover process. Therefore, the cover 15 is provided to avoid this risk.

[0024] In another embodiment, combined Figure 1 and Figure 2 As shown, the cover 15 is a transparent cover to facilitate real-time observation by the operator.

[0025] In another embodiment, combined Figure 1 and Figure 2 As shown, the workbench 1 is also equipped with four cylinders 16 that drive the first push block 4, the second push block 5, the third push block 6 and the fourth push block 10 to move.

[0026] In another embodiment, combined Figure 1 and Figure 2 As shown, the workbench 1 is also provided with a mounting base 17 for a corresponding drilling machine. The mounting base 17 is located behind the fourth push block 10 to make the layout reasonable.
