Description

Technical Field

[0001] The utility model relates to the technical field of punching processing, and more specifically, to a punching device. Background Art

[0002] During the production process of some workpieces, such as sheet metal parts, it is necessary to punch holes in the workpieces. This is accomplished using an automated punching device, typically using a pair of punches punching from both sides of the workpiece. A waste channel is provided inside one of the punches, and the other punch pushes the punched waste into the waste channel, ultimately producing the finished product. However, in some working conditions, such as when the punching waste is small or when there is oil on the workpiece surface, the other punch can easily carry the punching waste out of the waste channel. If the punching waste falls onto the mold surface or the workpiece surface, it can cause damage to the workpiece or damage to the mold, resulting in product failure. Utility Model Content

[0005] In the technical solution of the present utility model, the workpiece to be punched is placed between the first punching module and the second punching module, and the workpiece is punched from both sides by the first punch and the second punch. The waste generated during the punching enters the first waste channel inside the second punch. Since the first punch is provided with a first high-pressure air flow channel, it can be connected to an external air source device to blow high-pressure air toward the first waste channel. This can effectively prevent the first punch from carrying the waste out of the first waste channel and prevent the waste from clogging in the first waste channel, thereby ensuring the quality of the workpiece punching process.

The other end of the third high-pressure air flow channel is used to connect to an external air source device.

[0013] In this solution, multiple high-pressure air flow channels are provided and connected in sequence, thereby facilitating connection to an external high-pressure air source device.

[0014] Furthermore, an inlet end of the third high-pressure air flow channel is connected to an air pipe joint.

[0020] Furthermore, the base is connected to a linear drive mechanism, and the movable end of the linear drive mechanism is connected to the second punching module.

[0021] In this solution, the second punching module is driven to move by a linear drive mechanism, so that the first punch and the second punch punch against each other to perform punching processing on the workpiece.

[0022] Furthermore, a slide rail is fixedly connected to the base, a slider is fixedly connected to the bottom of the second punching module, and the slide rail is slidably connected to the slider.

[0023] In this solution, the slide rail and the slider guide the movement of the second punching module and can also play a bearing role in the vertical direction.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The punching device of the present invention places the workpiece to be punched between a first punching module and a second punching module, and punches the workpiece from both sides using a first punch and a second punch. Waste generated during punching enters a first waste channel within the second punch. Because the first punch is provided with a first high-pressure air flow channel, it can be connected to an external air source device to blow high-pressure air toward the first waste channel.

[0033] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0034] Example 1

[0035] refer to Figures 1 to 4 This embodiment discloses a punching device, including a base 1, a first punching module 2 and a second punching module 3. The first punching module 2 is fixedly connected to the base 1, and the second punching module 3 is movably connected to the base 1 in a direction close to or away from the first punching module 2. The first punching module 2 is fixedly connected to a first punch 4, and the second punching module 3 is fixedly connected to a second punch 5 arranged opposite to the first punch 4. A first waste channel 51 is axially penetrated in the interior of the second punch 5, and a first high-pressure air flow channel 41 is axially penetrated in the interior of the first punch 4. The high-pressure air flow channel is used to connect to an external air source device.

[0036] In this embodiment, the workpiece to be punched is placed between the first punching module 2 and the second punching module 3, and the workpiece is punched from both sides by the first punch 4 and the second punch 5. The waste generated during punching enters the first waste channel 51 inside the second punch 5. Since the first punch 4 is provided with a first high-pressure air flow channel 41, it can be connected to an external air source device to blow high-pressure air toward the first waste channel 51. This can effectively prevent the first punch 4 from carrying the waste out of the first waste channel 51 and prevent the waste from being blocked in the first waste channel 51.

The conical groove at the entrance of the punch mounting groove 21 can guide the second punch 5 so that the first punch 4 and the second punch 5 are hedged in the conical groove.

[0040] In this embodiment, the first punching module 2 has a working plane 22 for placing the workpiece to be punched, and the first punch 4 and the second punch 5 are respectively located on either side of the working plane 22. Specifically, the working plane 22 can be the side surface where the first punching module 2 and the second punching module 3 meet. The working plane 22 is used to place the workpiece to be punched. The workpiece to be punched can be placed directly on the working plane 22 or fixed to the working plane 22 via other fixing members. During punching, the working plane 22 can provide a certain degree of support for the workpiece to be punched.

[0041] In some preferred embodiments, a guide groove may be further provided on the first punching module 2, and a guide block corresponding to the guide groove may be provided on the second punching module 3. The guide groove of the first punching module 2 opens toward the second punching module 3, and the guide block of the second punching module 3 extends toward the first punching module 2. When the second punching module 3 moves toward the first punching module 2, the guide groove and the guide block play a positioning and guiding role, so that the first punch 4 and the second punch 5 can be accurately docked during punching.
