DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , a fin punching device for a radiator is provided, and the specific implementation of the utility model is described in detail below in combination with specific embodiments:

[0025] Example 1

[0026] See also Figure 1 The truss 10 is fixedly connected to the ground, and the ground may also be other bearing structures to maintain the overall stability.

[0027] See also Figure 1 , Figure 2 The frame 20 is arranged on the truss 10, and a punching plate 30 and a power assembly 40 are arranged on the frame 20. The power assembly 40 is used to drive the punching plate 30 to punch downward. There is a punching knife at the bottom of the punching plate 30. The number and distribution position of the punching knife are determined according to the through holes actually required on the fin.

[0028] See also Figure 1 , Figure 3 The motion assembly 50 includes a first motor body 51 mounted on the truss 10 and a movable frame 52 rotatably connected to the truss 10. The movable frame 52 has a plurality of processing positions. The first motor body 51 is connected to the movable frame 52 through a gear set 53, and is used to drive the plurality of processing positions to circulate under the punch plate 30. The second motor body 41 has a self-locking function, and its output shaft will not rotate after the drive stops.

[0029] See also Figure 1 , Figure 3 There are multiple carrier plates 60, and multiple carrier plates 60 are correspondingly arranged on each processing position. There are multiple receiving holes distributed on the carrier plate 60, and the receiving holes are through holes corresponding to the punching knife, so that the punching knife can discharge the punched waste along the receiving holes. The waste discharged downward falls during the rotation of the movable frame 52, and will not affect the punching process.

[0030] The carrier plate 60 supports the blank. The carrier plate 60 keeps horizontal as the processing position passes under the punching plate 30 and stays there to perform the punching process. After the punching is completed, it leaves so that the next station can immediately fill in and perform the punching process again, which effectively improves the punching efficiency.

[0031] See also Figure 3 A cover plate 70 and a fixing assembly 80 are provided on the carrier plate 60. The cover plate 70 and the carrier plate 60 form a side groove into which the blank can be inserted. The fixing assembly 80 is used to position the blank inserted in the side groove.

[0032] When placing the workpiece, a station on the side is in a vertical state, and the side groove opening on the station is vertically facing upward. The blank will not fall out after being inserted into the side groove, and the punching area of ​​the blank is exposed. The blank is then positioned by the fixing component 80, so that each blank maintains a consistent relative position with the punching plate 30 during the punching process, and the processing accuracy is high.

[0033] Example 2

[0034] See also Figure 2 A plurality of straight columns 31 are arranged on the punch plate 30 , and the plurality of straight columns 31 are vertically penetrated through the frame 20 , and a first spring 32 is wound around each of the straight columns 31 .

[0035] See also Figure 2 The power assembly 40 includes a second motor body 41 mounted on the frame body 20 and a support rod 42 rotatably connected to the frame body 20 . The support rod 42 is provided with a cam body 43 in contact with the punch plate 30 . The output shaft of the motor body is connected to the support rod 42 .

[0036] The second motor body 41 drives the support rod 42 to rotate, driving the cam body 43 to rotate and press the punch plate 30 to perform the punching process on the blank. After the punch plate 30 is pressed down, it can be reset upward by the first spring 32, thereby realizing multiple punching processes.

[0037] Example 3

[0038] See also Figure 3 , Figure 4 The fixing assembly 80 includes a first electric cylinder body 81 mounted on the carrier plate 60 . The movable rod of the first electric cylinder body 81 penetrates into the side groove and is connected to a push plate 82 . The push plate 82 can push the blank against the inner wall of the cover plate 70 .

[0039] That is, the push plate 82 is driven by the extension of the movable rod of the first electric cylinder body 81 to push the blank against the inner wall of the cover plate 70 to complete the positioning.

[0040] See also Figure 3 , Figure 4 The fixing assembly 80 further includes a plurality of second springs 83 disposed on the inner top wall of the cover plate 70 , the plurality of second springs 83 are connected to a lining plate 84 , and a plurality of balls 85 that can contact the blank are disposed on the lining plate 84 .

[0041] The lining plate 84 drives the balls 85 to contact the blank under the elastic force of the multiple springs, pressing the blank onto the carrier plate 60, so that the workpiece is contacted by the balls 85 during positioning and movement, and will not deflect.

[0042] See also Figure 3 , Figure 4 The cover plate 70 is mounted with a second electric cylinder body 86 , and a movable rod of the second electric cylinder body 86 penetrates into the side groove and is connected with the lining plate 84 .

[0043] After the punching process is completed, the blank becomes a fin, and moves with the station on the carrier 60 to the other side where the blank is placed and is in a vertical state. The side slot on the station opens vertically downward. At this time, the movable rods of the first electric cylinder body 81 and the second electric cylinder body 86 are both retracted, the push plate 82 is separated from the fin, and the lining plate 84 compresses the second spring 83 upward to drive a number of balls 85 to also separate from the fin, so that the fin falls by its own gravity to complete the discharge, without manual material removal. Of course, the fall of the fin requires a flexible material to support it from below or to be manually received to avoid deformation and damage to the fin.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
