[0017] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please refer to Figures 1 to 4 , wherein Figure 1 is a schematic structural diagram of the punching and flanging device for the muffler cylinder body of the present invention, Figure 2 is a schematic structural diagram of the punching and flanging device for the muffler cylinder body of the present invention, Figure 3 is a partial schematic structural diagram of the punching and flanging device for the muffler cylinder body of the present invention, Figure 4 is a local schematic structural diagram of the punching and flanging device for the muffler cylinder body of the present invention.

[0019] The present invention provides a punching and flanging device for a muffler cylinder body, including a lower plate body 101, a plurality of guide assemblies 102, a buffer assembly 103, an upper plate body 104, an upper die 105, a punch 106, a mounting seat 107, a plurality of first springs 108, a fitting member, a flanging head 109 and an end face positioning assembly. The guide assemblies 102 are all arranged between the lower plate body 101 and the upper plate body 104. The buffer assembly 103 is also arranged between the lower plate body 101 and the upper plate body 104. The upper die 105 is arranged on the upper plate body 104. The punch 106 is fixedly connected to the upper die 105. The mounting seat 107 is fixedly connected to the lower plate body 101. The fitting member is slidably connected to the mounting seat 107. The first spring 108 is arranged between the mounting seat 107 and the fitting member. One end of the flanging head 109 is fixedly connected to the mounting seat 107. The flanging head 109 is fixedly connected to the mounting seat 107. The fitting member is provided with a through hole 117 and a limit block 118 adapted to the flanging head 109. The end face positioning assembly is arranged on one group of the guide assemblies 102.

[0020] For this specific embodiment, during actual use, place the muffler cylinder body on the fitting member, and make one end of the muffler cylinder body contact the limiting block 118. Limit the other end of the muffler cylinder body through the positioning assembly. Then, drive the upper plate body 104 to move downward by an external device. The upper plate body 104 drives the upper die 105 to move. When the upper die 105 moves, it will drive the punch 106 to move until the punch 106 contacts the muffler cylinder body and continues to move downward to complete punching. After punching is completed, the upper plate body 104 continues to move downward. The upper die 105 can drive the muffler cylinder body to move downward, drive the fitting member to move downward, and drive the first spring 108 to contract. At this time, since the flanging head 109 is fixedly connected to the mounting seat 107, the flanging head 109 will not move. The flanging head 109 will then generate a relative displacement with the through hole 117 until the flanging head 109 pushes out and flanges the punched hole, thus completing the punching and flanging processes. In this way, it solves the technical problem in the prior art that the existing method usually uses a punching die to punch holes and then uses a flanging die to perform flanging processing on the muffler cylinder body. This process requires repeated positioning of the muffler cylinder body, resulting in low processing efficiency.

[0021] Wherein, the fitting member includes a slide bar 110 and an upper end fitting plate 111. The slide bar 110 is slidably connected to the mounting seat 107, and the upper end fitting plate 111 is fixedly connected to the slide bar 110.

[0022] For this specific embodiment, when the muffler cylinder body moves downward, it drives the upper end fitting plate 111 to move, and the upper end fitting plate 111 drives the slide bar 110 to slide on the mounting seat 107.

[0023] Secondly, the end face positioning assembly includes a motor 112, a connecting block 113, and a positioning block 114. The motor 112 is installed on the corresponding guiding assembly 102. The output end of the motor 112 is fixedly connected to the connecting block 113, and the positioning block 114 is fixedly connected to the connecting block 113.

[0024] For this specific embodiment, start the motor 112. The output end of the motor 112 drives the connecting block 113 to rotate, and the connecting block 113 drives the positioning block 114 to rotate to limit the corresponding end face of the muffler cylinder body.

[0025] Meanwhile, the muffler cylinder body punching and flanging device further includes a lower end fitting plate 115. The lower end fitting plate 115 is fixedly connected to the mounting seat 107.

[0026] For this specific embodiment, the lower end fitting plate 115 can limit the inner lower end of the muffler cylinder body.

[0027] In addition, the muffler cylinder punching and flanging device further includes a second spring 116, and both ends of the second spring 116 are fixedly connected to the upper end fitting plate 111 and the mounting seat 107 respectively.

[0028] For this specific embodiment, the second spring 116 can improve the shock absorption effect of the upper end fitting plate 111.

[0029] When using a muffler cylinder punching and flanging device of this embodiment, during specific use, place the muffler cylinder on the fitting member, and make one end of the muffler cylinder contact the limiting block 118. Limit the other end of the muffler cylinder through the positioning assembly. Then, drive the upper plate body 104 to move downward by an external device. The upper plate body 104 drives the upper die 105 to move. When the upper die 105 moves, it will drive the punch 106 to move until the punch 106 contacts the muffler cylinder and continues to move downward to complete punching. After punching is completed, the upper plate body 104 continues to move downward. The upper die 105 can drive the muffler cylinder to move downward, drive the fitting member to move downward, and drive the first spring 108 to contract. At this time, since the flanging head 109 is fixedly connected to the mounting seat 107, the flanging head 109 will not move. The flanging head 109 will then generate a relative displacement with the through hole 117 until the flanging head 109 pushes out and flanges the punched hole, and thus the punching and flanging processing can be completed. In this way, it solves the technical problem in the prior art that the existing method usually uses a punching die to punch holes and then uses a flanging die to perform flanging processing on the muffler cylinder. This process requires repeated positioning of the muffler cylinder, resulting in low processing efficiency.

[0030] What is disclosed above is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of rights of the present invention. Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
