[0046] The first punching device 5 is arranged between the second punching device 6 and the pressing device 4, the distance between the pressing device 4 and the tensioning portion 13 is smaller than the distance between the first punching device 5 and the tensioning portion 13, a stamping area is arranged between the upper plate 21 and the lower plate 22, the first punching device 5, the pressing device 4, and the second punching device 6 are all arranged in the stamping area and the stamping area is divided into several areas, the pressing device 4 is located in the first area, the first punching device 5 is located in the second area, the second punching device 6 is located in the third area, and the first plate body 33 passes through the first area, the second area, and the third area in sequence.

[0047] In this example, see Figure 1 - Fig.14When in use, the flat plate 31 is transferred from the feed part 12 to the tensioning part 13 and then enters the stamping area. The first plate body 33 is the part of the flat plate 31 that enters the stamping area. The material of the flat plate 31 is oxygen-free copper, phosphorus deoxidized copper and other materials. The thickness of the flat plate 31 is 2-3 mm, and the thickness of the flat plate 31 is thin. When the first plate body 33 moves to the first area, the first plate body 33 is located below the pressing plate 41. The first plate body 33 is composed of a first sub-plate 46 and a second sub-plate 47. The second sub-plate 47 is located directly below the pressing plate 41. The arc plate 43, the side plate 42, and the flat plate 31 together form a template. The second sub-plate 47 is located directly above the template. The telescopic member 18 sequentially presses the upper plate 21 and the pressing plate 41 downward. The pressing plate 41 is adapted to the template. The pressing plate 41 and the template are the same size and shape. The arc plate 43 first contacts and squeezes the second sub-plate 47. The arc plate 43 and the second sub-plate 47 The small contact area facilitates the deformation of the second split plate 47 under stress, and then the side plate 42 contacts and squeezes the second split plate 47. Due to the thin thickness and high plasticity of the flat plate 31, the second split plate 47 is concave under the squeezing action of the pressing plate 41, and the concave part of the second split plate 47 is in contact with the template, which plays a supporting and shaping role. Under the joint action of the pressing plate 41 and the template, the compressed part of the second split plate 47 is concave from the flat plate 31 to a V-shaped plate, and a V-shaped first pressing groove 48 is formed on the top of the second split plate 47. The shapes of the V-shaped plate and the first pressing groove 48 are the same as those of the pressing plate 41. The angle between the side panel 42 and the horizontal plane is 20°-30°. When the angle between the side panel 42 and the horizontal plane is 20°, the stretching degree of the second sub-panel 47 is small, the deformation amount is small, and the toughness requirement for the second sub-panel 47 is low; when the angle between the side panel 42 and the horizontal plane is 30°, the stretching degree of the second sub-panel 47 is large, and the contact area between the second sub-panel 47 and the external environment is large. Next, the first plate body 33 continues to move forward, and the first plate body 33 moves to the second area. The first sub-plate 46 is located directly below the first punch 55, and the second sub-plate 47 is located directly below the cross plate 51. The telescopic member 18 moves downward with the upper plate 21, the first punch 55, the cross plate 51, and the ring plate 52. The first punch 55 is cylindrical. The first punch 55 first contacts and squeezes the first sub-plate 46, and continues to move downward. The ring plate 52 and the cross plate 51 simultaneously contact and squeeze the first plate body 33 and form a second pressing groove 57 and a third pressing groove 58 respectively. The spring 53 is compressed to relieve the pressure to prevent the ring plate 52 and the cross plate 51 from moving downward too far. The second pressing groove 57 is circular, and the third pressing groove 58 is a straight notch. The first punch 55 penetrates the first sub-plate 46 and forms a first punching hole 56.The first plate body 33 continues to move forward, and the first plate body 33 moves to the third area. The second split plate 47 is located directly above the mold plate 61. The mold plate 61 is the same as the template. The telescopic member 18 moves downward with the upper plate 21, the second punch 62 and the third punch 63. The second punch 62 and the third punch 63 are squeezed and penetrate the first pressing groove 48 to form a second punching hole 66 and a third punching hole 67. The downwardly moved second punch 62 is inserted into the first type hole 64, and the downwardly moved third punch 63 is inserted into the second type hole 65. The second punch 62 and the third punch 63 are positioned by the first type hole 64 and the second type hole 65 respectively. The support of the mold plate 61 prevents the convex V-shaped plate from deforming during extrusion, thereby ensuring the shape of the finished product and improving the quality of the finished product. There are several profiling devices 4, first punching devices 5, second punching devices 6, mold plates 61, and templates, and the distribution methods are the same. Adjacent profiling devices 4 are staggered and distributed, and the separated profiling devices 4 are distributed in parallel, so that the adjacent first plate bodies 33 are also staggered. A second sub-plate 47 is sandwiched between the two first sub-plates 46. The second sub-plate 47 is provided with a second punching hole 66 and a third punching hole 67. The second punching hole 66 and the third punching hole 67 are equivalent to being opened in the middle of the two first sub-plates 46, and the gas flow effect is better. The second sub-plate 47 is pressed into a V-shaped plate, and the contact area between the outer side of the V-shaped plate and the environment is large, which can increase the amount of gas passing through per unit time and improve the heat dissipation efficiency.

[0048] In summary, in this embodiment, a punching line for the first plate body 33 is formed by the profiling device 4, the first punching device 5, and the second punching device 6, so that the horizontal second sub-plate 47 is extruded to form a V-shaped plate and multiple holes are opened, the number of windows is increased, the contact area between the window outlet and the environment is increased, the heat dissipation and air outlet effects are improved, and the adjacent first plate bodies 33 are staggered so that the second sub-plate 47 is located in the middle of two adjacent first sub-plates 46, and the distance between the opened air holes and the first punching holes 56 is short, thereby increasing the effect of gas flow. Example 2

[0049] Reference Figure 1 - Fig.16A punching device for producing a gas water tank core group includes: a first plate body 33 is connected to a side strip 32, and a side material processing device 8 is provided at an end of the lower plate 22 away from the tensioning portion 13. The side material processing device 8 is used to cut off the side strip 32 on the first plate body 33. The side material processing device 8 includes: a saw body 81, the saw body 81 is installed at an end of the lower plate 22 away from the tensioning portion 13, and a first side plate 83 is provided on the side of the saw body 81 away from the tensioning portion 13. The bottom of the first side plate 83 is connected to the top of the lower plate 22, and the side of the first side plate 83 close to the side strip 32 is located in the same plane as the side of the saw body 81 close to the side strip 32. The thickness of one side plate 83 is not greater than the thickness of the saw body 81. The side of the first side plate 83 close to the side strip 32 is connected to the second side plate 85 through the second connecting plate 84. The bottom of the first side plate 83 is connected to the third connecting plate 86 through the fourth connecting plate 87. The side of the third connecting plate 86 away from the first side plate 83 is connected to the second side plate 85. The top of the first side plate 83 is connected to the baffle plate 82. The bottom of the baffle plate 82 is connected to the top of the second side plate 85. The projection width of the third connecting plate 86 is greater than the thickness of the side strip 32. A channel is opened through the upper surface of the lower plate 22. The second side plate 85 is a quadrilateral, and both waists of the quadrilateral are curves.

[0050] In this example, see Figure 1 - Fig.14 When in use, in order to ensure the quality of the finished product, the width of the flat plate 31 is greater than the required width of the finished product, so the excess side strips 32 are cut off by the saw body 81. In order to prevent impurities from accumulating in the stamping area, the cut garbage waste needs to be discharged in time. The first side plate 83, the second side plate 85, the second connecting plate 84, the third connecting plate 86, and the fourth connecting plate 87 form a material guide box, and a material guide cavity is opened in the material guide box. The side strips 32 after cutting are no longer connected to the first plate body 33. The side strips 32 sag under the action of gravity and enter the material guide cavity. If the discharge speed of the first plate body 33 is fast, the moving speed of the side strips 32 is also fast. Before the side strips 32 have time to sag, the top of the baffle 82 is located above the top of the side strips 32. The baffle 82 blocks the fast-moving side strips 32, so that the side strips 32 fall into the material guide cavity after the collision. The third connecting plate 86 has a large curvature, and the side strips 32 slide into the channel along the third connecting plate 86 without manual processing. The side strips 32 are blocked and guided by the material guide box, and the gravity of the side strips 32 themselves is used as the power to complete the collection of the side strips 32, saving time and effort.

[0051] In summary, in this embodiment, the excess edge strips 32 are cut off by the edge material processing device 8, and the drooping edge strips 32 are guided by the material guide box composed of the first side plate 83, the second side plate 85, the second connecting plate 84, the third connecting plate 86, and the fourth connecting plate 87, so that the collection of the edge strips 32 can be easily completed without manpower.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0053] The above is only a preferred embodiment of the present invention.
