Description

Technical Field

[0001] The utility model relates to the technical field of fin processing, in particular to a fin mounting hole processing device. Background Art

[0002] A heat pump is an efficient and energy-saving device that makes full use of low-grade thermal energy and forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It is mainly composed of a compressor, a condenser, a throttle valve, an evaporator and other components. The evaporator mainly adopts a finned evaporator. As the name suggests, its main structure is a fin. During production, it is necessary to process mounting holes on the fins for installing components such as steam pipes. In the prior art, a plate is usually moved to the bottom of a punching machine manually for punching. However, a punching machine generally has only one punch. When performing the punching operation, the fin needs to be continuously moved. Multiple mounting holes can be processed on the fins through multiple punchings, which is not conducive to improving production efficiency. At the same time, during the actual operation, workers may cause physical injuries due to operational errors. In addition, due to the use of multiple punchings, the positioning of the fins may be inaccurate during each punching, which causes the position of the mounting holes on the fins to shift. When the steam pipe is installed on the fin, it may be that the steam pipe cannot pass through the mounting hole, which affects the normal production. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0020] like Figure 1-Figure 4 As shown, this example provides a fin mounting hole processing device, including: a base 100, a limiting component 200, and a punching component 300.

[0021] Partitions 101 are provided on both sides of the length direction of the base 100. When the fins are placed on the base 100, the partitions 101 are used to limit the two sides of the fins; the limiting assembly 200 includes two pressure plates 201 respectively located on both sides of the length direction of the base 100 and moving in the vertical direction, which are used to limit the top surface of the tooth plate, and baffles 202 and limiting blocks 203 moving in the vertical direction are also provided at both ends of the pressure plate 201, which are used to limit the two ends of the fins; the punching assembly 300 is arranged above the base 100, including a lifting plate 301 moving in the vertical direction, and a plurality of punch rods 302 are provided on the bottom surface of the lifting plate 301 in a rectangular array, which are used to punch mounting holes on the fins.

[0022] Specifically, the base 100 is provided with a plurality of grooves 102 along its length direction. The length direction of the grooves 102 is parallel to the width direction of the base 100, and both ends pass through the base 100. When performing the stamping operation, the lower end of the punch rod 302 will enter the groove 102 to ensure that the mounting hole is smoothly stamped out on the fin. In order to avoid the punched discs from accumulating in the groove 102, a through groove 103 is also provided on the bottom surface of the groove 102 along its length direction. A push plate 104 is provided in the groove 102. The lower end of the push plate 104 passes through the through groove 103 and is connected to a movable plate 105. The movable plate 105 is connected to the movable end of the horizontal linear mechanism. The horizontal linear mechanism is installed on the bottom surface of the base 100. After the stamping is completed, the punch rod 302 rises, and at the same time, the horizontal linear mechanism drives the push plate 104 to move from the groove 102 to the other end, thereby pushing the punched disc out from one end of the groove 102. In order to facilitate the collection of the discs, a collection frame can also be set on both sides of the base 100.

[0023] Specifically, in order to adapt to fins of different thicknesses and facilitate the movement of the fins to the base 100, a connecting plate 204 is provided on the outside of the pressing plate 201, and a limiting groove 106 is provided on the side of the partition 101 in the vertical direction. The connecting plate 204 is inserted into the limiting groove 106 and sleeved on the vertical rod 107. Both ends of the vertical rod 107 are installed on the convex plate 108. The convex plate 108 is installed on the outside of the partition 101. The vertical rod 107 is also sleeved with a first spring 205. The first spring 205 The two ends respectively abut against the convex plate 108 and the connecting plate 204 located above, and are always in a compressed state. When the fin gradually moves to the base 100, the pressure plate 201 will be pushed upward. At this time, the first spring 205 is also further compressed until one end of the fin abuts against the baffle 202, and the other end contacts the side of the limit block 203. At this time, the fin will be pressed against the base 100 under the elastic force of the first spring 205, thereby achieving the limitation of the fin.

[0024] Specifically, in order to enable the fin to smoothly lift the pressure plate 201, an arc portion 207 is provided at one end of the pressure plate 201 close to the limit block 203, and the end of the arc portion 207 is bent upward. When the fin moves to the base 100, its edge will first contact the arc portion 207, thereby forcing the pressure plate 201 to move upward.

[0025] Specifically, the upper end of the baffle 202 is mounted on the cross bar 206, and both ends of the cross bar 206 are connected to the movable end of the vertical lifting mechanism. The vertical lifting mechanism is installed on the outside of the base 100. After the stamping is completed, the baffle 202 is driven to move upward by the vertical lifting mechanism, thereby releasing the limit on one end of the fin to facilitate the fin to be pushed out.

[0026] Specifically, the side of the limit block 203 away from the center of the base 100 is arc-shaped, and the lower end is penetrated in the base 100. When the fin is moved onto the base 100, the edge of the fin will first contact the arc-shaped part of the limit block 203 and force the limit block 203 to move downward. In order to enable the limit block 203 to bounce upward after moving downward to limit the end of the fin, a thrust plate 208 is also provided at the bottom of the limit block 203, and a push rod 209 is provided at the bottom of the thrust plate 208. The push rod 209 is penetrated in the mounting plate 109, and a second spring 210 is also sleeved on the push rod 209. The two ends of the second spring 210 respectively abut against the mounting plate 109 and the thrust plate 208, and are always in a compressed state. After the fin has completely passed the limit block 203, the limit block 203 will pop up under the action of the second spring 210.

[0027] Specifically, a slide groove 303 is provided at one end of the lifting plate 301 and extends to the other end. A plurality of support plates 304 are passed through the slide groove 303 and locked with screws. A plurality of screw rods 305 are provided on the bottom surface of the support plate 304 along its length direction. A plurality of long holes 306 are also provided at the bottom of the slide groove 303 along its length direction. The length direction of the long holes 306 is parallel to the width direction of the slide groove 303, and the screw rods 305 pass through the long holes 306. The punch rod 302 is installed on the screw rod 305. The punch rod 302 can be replaced as needed. At the same time, the support plate 304 can be moved to adjust the spacing between the punch rods 302 between two adjacent support plates 304.

[0028] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
