Description

Technical Field

[0001] The present application relates to the technical field of cooling tower fin processing, and in particular to a punching head for cooling tower fins. Background Art

[0002] For cooling towers, the heat sink is its most core component. The entire process of heat dissipation in the cooling tower is completed inside the heat sink. During the production of the heat sink, it is necessary to open holes in the heat sink so that water pipes or air ducts can pass through the heat sink and the heat exchange medium can dissipate heat through the heat sink.

[0003] A cooling tower fin punching head is a punching tool mounted on the output shaft of a punching device and driven by the punching device to contact the fins. Existing fin punching heads typically consist of a punch head and a connector for attaching the punch head to the active end of the punching device. The punch head is cylindrical in shape. Driven by the active end of the punching device, the punch head is pressed downward, bringing the blade of the open end of the punch into contact with the fins to complete the punching operation. However, due to the cylindrical shape of the punch head, waste material easily enters the punched hole after punching, making it difficult to clean and extremely inconvenient to use.

[0004] Therefore, the present application provides a punching head for cooling tower fins that can automatically withdraw materials to solve the above problems. Utility Model Content

[0005] The present application provides a punching head for cooling tower fins, which aims to solve the problem in the prior art that waste materials easily enter the interior of the punching head during use and are difficult to clean.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a punching head for cooling tower fins, comprising a punch, the punch being cylindrical, one end of the punch having a connection portion for connecting to a movable end of a punching device; the punching head also comprising a material stripping structure arranged inside the punch; the material stripping structure comprising a pressure plate that moves axially inside the end of the punch away from the connection portion and an elastic component arranged inside the punch, the two ends of the elastic component being connected to the punch and the pressure plate respectively; wherein, when the elastic component is in a released state, the end of the pressure plate away from the elastic component extends out of the end of the punch away from the connection portion. In this way, when the punching is completed, the elastic force of the elastic component pushes the pressure plate to move and extend, thereby pushing out the waste material remaining inside the punch, thereby completing the material stripping work, reducing the risk of waste material remaining inside the punch, and eliminating the need for subsequent manual cleaning, making it easy to use.

[0007] Preferably, the elastic component is a spring.

[0008] Preferably, a first spring seat and a second spring seat connected to the punch and the pressure plate respectively are provided at both ends of the elastic component.

[0009] Preferably, a flange connected to the punch is fixedly provided on one end of the first spring seat away from the elastic component.

[0010] Preferably, the pressure plate is welded to the second spring seat.

[0011] The punching head has a simple structure and is easy to use. By setting a material return structure, after punching is completed, the waste material is separated from the punch head under the elastic force of the elastic component, which can effectively prevent the waste material from remaining in the punch head and eliminates the need for manual cleaning.

[0017] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] The present application provides a punching head for cooling tower fins, such as Figure 1 As shown, the punch head includes a punch 1, which is cylindrical and has a connecting portion 2 at one end for connecting to the movable end of the punching device. In this way, when the blade of the open end of the punch 1 contacts and continuously applies pressure to the heat sink, the heat sink is punched.

[0019] In order to discharge the waste material after punching from the punch head 1, unlike the traditional cooling tower heat sink punching head, this punching head also includes a material removal structure 3 arranged inside the punch head 1. After the punching is completed and the punch head 1 is separated from the heat sink, the material removal structure 3 pushes the punched waste material out of the inside of the punch head 1, thereby completing the material removal work and reducing the risk of waste material remaining inside the punch head 1.

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the material stripping structure 3 includes a pressure plate 31 that moves axially inside the end of the punch 1 away from the connecting portion 2, and an elastic component 32 disposed inside the punch 1. The two ends of the elastic component 32 are respectively connected to the punch 1 and the pressure plate 31. When the elastic component 32 is released, the end of the pressure plate 31 away from the elastic component 32 extends out of the end of the punch 1 away from the connecting portion 2. Optionally, the elastic component 32 is a spring.

[0021] When the movable end of the punching device pushes the punch 1 to move and contact the heat sink to punch a hole, the pressure plate 31 first contacts the area to be punched. As it continues to move, it overcomes the elastic force of the elastic component 32 and causes the blade edge of the open end of the punch 1 to contact the heat sink, completing the punching of the heat sink. When the punching is completed and the punch 1 is separated from the heat sink, the elastic force of the elastic component 32 pushes the pressure plate 31 out from the inside of the punch 1, thereby pushing out the waste material remaining in the punch 1, thereby preventing the waste material from remaining inside the punch and eliminating the need for manual post-processing cleaning.

[0022] In order to install the elastic component 32 inside the punch 1 to support the pressure plate 31 and ensure the stability of the stripping mechanism 3, a first spring seat 33 and a second spring seat 34 are provided at both ends of the elastic component 32, which are connected to the punch 1 and the pressure plate 31 respectively. The pressure plate 31 is fixedly connected to the second spring seat 34, and a flange 331 connected to the punch 1 is fixedly provided at the end of the first spring seat 33 away from the elastic component 32.

[0023] It should be noted that the flange 311 and the punch 1 can be fixedly assembled by connecting parts, such as drilling a hole on the punch 1 and passing a bolt through the hole to screw it to the flange 331; the flange 331 and the first spring seat 33 and the pressure plate 31 and the second spring seat 34 can be fixedly assembled by welding.

[0024] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
