Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat dissipation fin processing, in particular to a heat dissipation fin drilling and cutting device. BACKGROUND

[0002] The heat dissipation fin is a commonly used heat exchange device in gas and liquid heat exchangers, and the heat dissipation fin is installed on the ordinary base pipe to achieve the purpose of strengthening heat transfer. In order to facilitate the installation of the heat dissipation fin, drilling is usually performed on the heat dissipation fin to realize the positioning installation of the heat dissipation fin.

[0003] Since the heat dissipation fin is a whole long strip when it is just processed, it usually needs to be drilled and cut, so that the installation hole is drilled on the installation position of the heat dissipation fin, and the heat dissipation fin is cut into the designed size.

[0004] However, for the drilling and cutting of the heat dissipation fin, the whole heat dissipation fin is usually cut into several segments by manual operation of the cutting machine, and then the cut heat dissipation fin is transported to the drilling process for positioning and calibration, and the drilling position is found, and then the heat dissipation fin is drilled by manual operation of the bench drill. Such processing method makes the processing period of the cutting and drilling of the heat dissipation fin longer, thereby resulting in lower processing efficiency of the heat dissipation fin.

[0020] The heat dissipation fins are cut and then conveyed to the discharge port for discharging treatment. The cut heat dissipation fins are stacked in the discharging frame for storage. When the discharging frame is filled with the heat dissipation fins, the pushing motor is controlled to rotate the pushing screw, thereby driving the pushing plate to push the discharging frame forward by a distance, so that the heat dissipation fins can be continuously stacked in the discharging frame, and the heat dissipation fins can be continuously stored.

[0021] In an embodiment, the discharging frame is provided with a plurality of partitions arranged along the length direction of the discharging frame, and the partitions divide the discharging frame into a plurality of storage areas. Each storage area of the discharging frame is provided with a guide plate on the side close to the discharge port. The guide plate comprises a vertical section and a bent section.

[0025] In one specific implementation, the control assembly comprises a positioning clamping plate, an unlocking block and a positioning spring, a mounting plate is slidably installed on the side wall of the sliding table in the vertical direction, the positioning clamping plate is installed on the top wall of the mounting plate, a plurality of push rods are installed on the bottom wall of the falling frame, the push rods are slidably connected with the sliding rod, the positioning clamping plate is used for limiting the push rods, the positioning spring is installed in the sliding table, one end of the positioning spring is connected with the bottom wall of the sliding table, and the other end is connected with the bottom wall of the mounting plate, the unlocking block is installed on the top wall of the mounting plate, and the unlocking block is used for being connected with the buffer rod, and the length of the unlocking block is the length of one storage area.

[0026] By adopting the technical scheme, when the heat dissipation fins reach the upper limit in one of the storage areas, the buffer rod abuts against the unlocking block and drives the unlocking block to move downward, so that the unlocking block drives the mounting plate to move downward, thereby driving the positioning clamping plate to move downward and separate from the push rod, then the push motor is actuated, so that the push motor drives the push lead screw to rotate, thereby driving the push plate to move, so that the push plate drives the falling frame to move along the sliding table, thereby driving the buffer rod to slide along the top wall of the unlocking block, when the buffer rod slides and separates from the unlocking block, the mounting plate moves upward and resets under the action of the positioning spring, so that the mounting plate separates from the control switch, thereby stopping the push motor from working, and meanwhile, the mounting plate drives the positioning clamping plate to reposition the push rod, thereby facilitating the falling frame to continue to store the heat dissipation fins.

[0027] In summary, the present application has at least one of the following beneficial effects:

[0028] 1. The present application sequentially sets a drilling device and a cutting device in the case, so that when the whole heat dissipation fin is fed into the case, it sequentially passes through the drilling station and the cutting station to form a processing line, thereby shortening the processing period of the heat dissipation fin, so as to improve the processing efficiency of the heat dissipation fin.

[0029] 2. The application sets a partition in the blanking frame, which separates the blanking frame into several storage areas for storing the heat dissipation fins through the partition, so as to fully utilize the space in the blanking frame and facilitate the neat arrangement of the heat dissipation fins.

[0060] Referring to Figure 7 The pushing screw rod 949 is rotatably installed on the side wall of the sliding table 941 in the length direction of the sliding table 941, and one end of the pushing screw rod 949 penetrates through the side wall of the sliding table 941. The pushing motor 948 is fixedly installed on the side wall of the sliding table 941, and the output shaft of the pushing motor 948 is coaxially connected with the end of the pushing screw rod 949. The pushing plate 947 is slidably installed on the side wall of the sliding table 941, and one end of the pushing plate 947 is threadedly connected with the pushing screw rod 949. The other end of the pushing plate 947 is used to push the side wall of the blanking frame 91. A control switch 9410 is fixedly installed below the installation plate 944 in the sliding table 941, and the control switch 9410 is used to contact with the installation plate. A display lamp (not shown in the figure) is also installed on the side wall of the sliding table 941, and the control switch 9410 is also used to control the display lamp to be on or off.

[0061] Referring to Figure 7 and Figure 8 When the new storage area 911 is completely aligned with the discharge port 12, the buffer rod 923 just slides away from the top wall of the unlocking block 946, at this time, the new buffer rod 923 is located above the unlocking block 946, the unlocking block 946 no longer receives the pushing force of the buffer rod 923, so that the mounting plate 944 moves upward to reset under the action of the positioning spring 945, thereby driving the unlocking block 946 and the positioning clamping plate 943 to move upward to reset, so that the mounting plate 944 is separated from the control switch 9410, thereby making the display lamp extinguished, then controlling the pushing motor 948 to stop working, so that the blanking frame 91 stops moving, at this time, the side wall of the right angle edge of the positioning clamping plate 943 just abuts against the push rod 914, thereby limiting the blanking frame 91.

[0062] Referring to Figure 8 and Figure 9 When the new storage area 911 is completely aligned with the discharge port 12, the buffer rod 923 just slides away from the top wall of the unlocking block 946, at this time, the new buffer rod 923 is located above the unlocking block 946, the unlocking block 946 no longer receives the pushing force of the buffer rod 923, so that the mounting plate 944 moves upward to reset under the action of the positioning spring 945, thereby driving the unlocking block 946 and the positioning clamping plate 943 to move upward to reset, so that the mounting plate 944 is separated from the control switch 9410, thereby making the display lamp extinguished, then controlling the pushing motor 948 to stop working, so that the blanking frame 91 stops moving, at this time, the side wall of the right angle edge of the positioning clamping plate 943 just abuts against the push rod 914, thereby limiting the blanking frame 91.

[0063] The working principle of the embodiment of the application is as follows: a whole heat dissipation fin is sent into the cabinet 1 from the feeding port 11, so that the heat dissipation fin is inserted into the feeding sleeve 21 in the feeding device 2, the feeding cylinder 22 is controlled to work, so that the feeding cylinder 22 positions the heat dissipation fin through the pressing plate 23, then the feeding sleeve 21 is pushed to the direction of the processing platform 7 through the pushing cylinder 25, so as to drive the whole heat dissipation fin to move to the processing platform 7, then the feeding cylinder 22 controls the pressing plate 23 to separate from the heat dissipation fin, and then the feeding sleeve 21 is moved to the initial position in the direction of the feeding port 11 through the pushing cylinder 25, so as to repeat the above steps to gradually send the heat dissipation fin into the cabinet 1.

[0064] When the heat dissipation fin moves to the drilling device 3, the first positioning cylinder 81 drives the first positioning block 82 to position the heat dissipation fin, the lifting mechanism 32 in the drilling device 3 drives the drilling mechanism 31 to descend, so as to drill the heat dissipation fin. After drilling, the first positioning cylinder 81 drives the first positioning block 82 to release the heat dissipation fin, and then the feeding device 2 drives the heat dissipation fin to move forward by a distance, so that the heat dissipation fin after drilling moves below the stamping device 4, at this time, the second positioning cylinder 83 drives the second positioning block 84 to position the heat dissipation fin, and then the stamping cylinder 42 drives the stamping head 43 to stamp the drilling position on the heat dissipation fin. After stamping, the second positioning cylinder 83 drives the second positioning block 84 to release the heat dissipation fin, and then the feeding device 2 drives the heat dissipation fin to move by a distance, so that the heat dissipation fin after drilling and stamping moves to the cutting limiting block 71, at this time, the third positioning cylinder 85 drives the third positioning block 86 and the fourth positioning cylinder 87 drives the fourth positioning block 88 to position the heat dissipation fin, and then the cutting device 5 cuts the heat dissipation fin.

[0065] After cutting, the heat dissipation fins are continuously fed into the cabinet 1 through the feeding device 2, and sequentially pass through the drilling device 3, the punching device 4 and the cutting device 5 for processing, and then the cut heat dissipation fins are pushed out to the discharge port 12 and fall into a storage area 911 in the drop frame 91. When the heat dissipation fins stored in the storage area 911 reach the upper limit, the buffer rod 923 presses the unlocking block 946, and the unlocking block 946 drives the mounting plate 944 to move downward, and presses the positioning spring 945 and the contact control switch 9410, so as to control the display lamp to light up, and the positioning clamp plate 943 is released from the positioning of the push rod 914, and then the push motor 948 is started to drive the push lead screw 949 to rotate, so as to control the push plate 947 to push the drop frame 91 along the length direction of the slide table 941, so as to align the new storage area 911 with the discharge port 12. At this time, the buffer rod 923 in the storage area 911 full of heat dissipation fins is separated from the unlocking block 946, so that the mounting plate 944 drives the unlocking block 946 to move upward under the action of the positioning spring 945, and the mounting plate 944 is separated from the control switch 9410, so as to control the display lamp to be turned off, and then the push motor 948 is stopped to work, so as to stop the drop frame 91 from moving, and the right angle edge of the positioning clamp plate 943 limits the push rod 914. Then the new storage area 911 in the drop frame 91 stores the heat dissipation fins again.

[0066] When each storage area 911 in the drop frame 91 is full of heat dissipation fins, the guide plate 93 is lifted out of the drop frame 91 by holding the handle 933 on the guide plate 93, so that the heat dissipation fins are lifted by the supporting plate 934 and taken away from the drop frame 91, so as to facilitate packaging of the heat dissipation fins stacked and stored in the storage area 911. Then the guide plate 93 is put back into the drop frame 91, so as to use the drop frame 91 to store the heat dissipation fins again.

[0067] The above is the preferred embodiment of the present application, which does not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
