Attached Figure Description

[0014] Figure 1 : Schematic diagram of the overall structure of the punching device. Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 As shown. A manual punching device includes a base 1 and a punching platform 2. A punching rod 11 that can be pressed down vertically is connected to the base 1. The punching platform 2 includes a movable base 21 and a support platform 22 rotatably connected above the movable base 21. The movable base 21 can drive the support platform 22 to move laterally. The support platform 22 is used to support and fix the workpiece and has a clearance area.

[0017] In this embodiment, the device can be used to complete the punching operation conveniently and efficiently. During operation, the workpiece position is quickly and accurately adjusted using the rotatable and laterally movable base 21. Once the workpiece position is determined, the vertically pressing punch rod 11 can be used to penetrate the workpiece surface to complete the punching operation. The operator can operate the positioning movable base 21 with one hand and operate the pressing punch rod 11 with the other hand to complete the punching operation of the entire workpiece.

[0018] In a more preferred embodiment, the base 1 includes guide posts 12 and a crossbeam 13 connected perpendicularly to each other. The punching rod 11 is vertically connected to the crossbeam 13. A pressing unit is also provided on the crossbeam 13, which can drive the punching rod 11 to move vertically downward. The pressing unit is mainly used to apply vertical downward pressure to the punching rod 11. The pressing unit is an independently operable force-applying component. After adjusting the workpiece position, the operator can operate the pressing unit to drive the punching rod 11 to move vertically downward to complete the punching.

[0019] In a more preferred embodiment, the pressing unit includes a pressing rod 14 hinged to the crossbeam 13 at one end, and a punching rod 11 passing through the crossbeam 13 with its top end extending beyond the upper surface of the crossbeam 13. When the pressing rod 14 is pressed down, it can drive the punching rod 11 to move vertically downward. This embodiment provides a possible implementation of the pressing unit. Specifically, the pressing rod 14 is connected to the crossbeam 13 through a hinged seat, and its other end is connected to an operating handle. When the operating handle is pressed down, the pressing rod 14 can drive the punching rod 11 to move vertically downward to complete the punching. The punching rod 11 and the pressing rod 14 can also be connected by a hinge. Under the guiding action of the punching rod 11 passing through the crossbeam 13, pressing down and lifting the pressing rod 14 can drive the punching rod 11 to move vertically downward reciprocally.

[0020] In a more preferred embodiment, the punching rod 11 is connected to the crossbeam 13 via a spring, and the pressing rod 14 can contact the top end of the punching rod 11 when it is pressed down. In this embodiment, the pressing rod 14 and the punching rod 11 are not directly connected. When the pressing rod 14 is pressed down, contact with the top end of the punching rod 11 can drive the punching rod 11 to move vertically downward. After the pressing rod 14 is lifted, the punching rod 11 springs back away from the workpiece surface under the action of the spring to complete the punching.

[0021] In a more preferred embodiment, one end of the crossbeam 13 is also connected to an adjustable limiting rod 15. The adjustable limiting rod 15 can adjust the length protruding from the upper surface of the crossbeam 13 to limit the downward stroke of the pressing rod 14. In this embodiment, although the supporting platform 22 has a clearance area, the height of this clearance area is limited. When the punching rod 11 punches vertically downward through the surface of the workpiece, if its stroke is not restricted, it is very likely to touch the surface of the supporting platform 22, causing damage to the punching rod 11. To avoid this problem, the adjustable limiting rod 15 is used to limit the downward stroke of the pressing rod 14, thereby limiting the punching stroke of the punching rod 11. In this embodiment, the adjustable limiting rod 15 uses a screw that passes through the crossbeam 13, and the limiting stroke can be easily adjusted using a nut.

[0022] In a more preferred embodiment, the crossbeam 13 is vertically connected to the guide post 12 via a lifting screw 16, and the top of the lifting screw 16 is connected to a lifting adjustment handwheel 18. In this embodiment, the crossbeam 13 is designed to be height-adjustable. Compared to a fixed height, the height-adjustable crossbeam 13 allows for a certain adjustable range of the punching stroke, making it suitable for punching workpieces of different heights. The operator can precisely adjust the height of the crossbeam 13 using the lifting adjustment handwheel 18.

[0023] In a more preferred embodiment, a fixed base 3 is located below the movable base 21. The fixed base is connected to the movable base 21 via a transverse guide rail 31. The top of the movable base 21 is connected to the support platform 22 via a rotating seat 23. The rotating seat 23 is connected to a rotary adjustment handwheel 25 via a synchronous belt 24. In this embodiment, the position of the workpiece can be adjusted by rotating the adjustment handwheel 25. When the holes are arranged in a ring, after the workpiece is positioned laterally, adjusting the rotary adjustment handwheel 25 drives the workpiece to rotate, thus completing the punching of the holes.

[0024] In a more preferred embodiment, the fixed base 3 is provided with a transverse lead screw 32, one end of which is connected to the movable base 21, and the other end is connected to a transverse adjustment handwheel 33. Similar to the above embodiment, the operator can use the transverse adjustment handwheel 33 to adjust the transverse position of the workpiece.
