Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a punching device for a panel buckle of a clothes drying machine. Background Art
[0002] During the production of clothes drying machines, to ensure the aesthetic appearance of the exterior of the panel, the panel and light panel are typically assembled using snap-fit connections. This involves pre-placing the light panel on the inside of the panel, and then using a stamping device to bend and flatten the snaps on the inside of the panel onto the light panel, achieving a non-detachable assembly. Currently, the punch used in the industry to flatten the snaps typically has an inclined pressing surface. This type of punch can cause a certain amount of sticking when stamping the snaps, and the punch pressure applied to the snaps is uneven, resulting in the snaps being easily broken during the stamping process or having a poor snap-fitting effect after stamping.

[0035] See Figures 1 to 6, this embodiment provides a punching device for a clothes drying machine panel buckle, specifically, the punching device includes a frame 1, a working platform 11 for placing the clothes drying machine panel 4 on the top of the frame 1; a driving device 2, the driving device 2 is arranged on the frame 1; a punch device 3 for flattening the clothes drying machine panel buckle, the punch device 3 is arranged above the working platform 11, the driving device 2 drives the punch device 3 to approach or move away from the working platform 11, the punch device 3 includes a connecting component 31 and a punch 32, the top of the connecting component 31 is installed on the driving end of the driving device 2, and the bottom is connected to the punch 32, the punch 32 is provided with a flattening part 321 at one end close to the working platform 11, and the flattening part 321 is provided with a plurality of mutually connected stamping surfaces with different slopes, and the slope of the stamping surface gradually increases along the direction approaching the working platform 11. The design of the stamping surface with different slopes can guide the material to flow more smoothly during the stamping process. The stamping surface with a larger slope at the end of the punch 32 helps the buckle to gradually expand in the initial stage, reducing the frictional resistance between the buckle and the punch 32. As the bending degree of the buckle increases, the slope of the stamping surface gradually decreases, and a smaller stamping angle is still maintained between the punch 32 and the buckle to reduce the frictional resistance, thereby improving the smoothness of the stamping. In addition, since the slope of the stamping surface gradually increases in the direction close to the working platform 11, the punch 32 can gradually apply pressure when contacting the buckle, which helps to reduce the sudden deformation of the material and internal stress concentration, thereby reducing the risk of cracking or abnormal deformation of the buckle. In addition, the stamping surfaces with different slopes help to better control the deformation of the buckle during the stamping process, thereby reducing dimensional deviations caused by material rebound or mold wear, and helping to improve the overall quality and consistency of the product.
[0036] Among them, the clothes drying machine panel 4 of the present application is provided with a through hole 41 in the middle part for cooperating with the light board 5, and a circle of raised parts 42 is provided on the inner side of the clothes drying machine panel 4 around the through hole 41, and the raised part 42 is provided with a clip 43 arranged around the through hole 41, and the clip 43 is provided with a light board placement part 431 and a part to be punched 432, one end of the light board placement part 431 is connected to the raised part 42, and is suspended parallel to the inner wall of the clothes drying machine panel 4, and the part to be punched 432 extends from the other end of the light board placement part 431 perpendicular to the light board placement part 431 toward the inner wall away from the raised part 42, and the light board 5 is placed on the light board placement part 431, and the punch device 3 bends the part to be punched 432 ninety degrees and flattens it onto the light board 5.

[0040] The punching device also includes an assembly plate 7, which is provided at the driving end of the drive device 2. The assembly plate 7 is parallel to the working platform 11, and a plurality of punch devices 3 are installed at the bottom of the assembly plate 7.

The cooperation between the sliding rod 23 and the sliding sleeve 24 prevents shaking during the lifting and lowering movement of the assembly plate 7, improving accuracy. Preferably, the sliding sleeves 24 are symmetrically arranged on both sides of the cylinder 22 to further enhance the stability of the lifting and lowering movement of the assembly plate 7. In other embodiments, the number of sliding sleeves 24 can also be three, four, or another number.

The locking rod 3121 passes through the assembly plate 7 and is threadedly locked with the locking hole 3113. The anti-loosening spring 3122 elastically abuts against the anti-loosening portion and the assembly plate 7. The anti-loosening spring 3122 makes the assembly between the assembly plate 7 and the connecting block 311 tighter, thereby improving the stability and safety of the stamping device. In another embodiment, the locking member 312 and the locking hole 3113 can also be connected by interference fit, pin connection or other methods. In another embodiment, the anti-loosening spring 3122 can also be replaced by an anti-loosening component such as a spring washer.
[0044] The connecting block 311 is provided with a plug hole 3114 extending along its length. The flattening portion 321 of the punch 32 extends out a plug portion 322 at one end away from the work platform 11. The plug portion 322 is plugged and fixed to the plug hole 3114. The plug portion 322 cooperates with the plug hole 3114 to fix the punch 32 on the connecting block 311 and limit the lateral movement of the punch 32, thereby improving the stamping accuracy. The plug hole 3114 is provided on the second connecting block 3112. In this embodiment, the extension degree of the flattening portion 321 can be adjusted by adjusting the amount by which the plug portion 322 can be inserted into the plug hole 3114, thereby facilitating the processing of the buckle 43.
[0045] The stamping surface includes a first stamping surface 3211, a second stamping surface 3212 and a third stamping surface 3213 which are sequentially arranged in a direction close to the working platform 11. The slope of the first stamping surface 3211, the slope of the second stamping surface 3212 and the slope of the third stamping surface 3213 increase successively, and the first stamping surface 3211, the second stamping surface 3212 and the third stamping surface 3213 form a "factory" shaped structure. During the stamping process, the third stamping surface 3213, the second stamping surface 3212 and the first stamping surface 3211 bend the clothes drying machine panel buckle in turn to improve the smoothness of the stamping. In other embodiments, the number of the stamping surfaces may also be 2, 4 or other numbers. In other embodiments, the stamping surface may also be an arc-shaped surface formed by several inclined surfaces with different slopes. The angle between the first stamping surface 3211 and the working platform 11 ranges from 4 degrees to 6 degrees. Preferably, the angle between the first stamping surface 3211 and the work platform 11 is 5 degrees. In another embodiment, the angle between the first stamping surface 3211 and the work platform 11 may also be 4 degrees or 6 degrees. The angle between the second stamping surface 3212 and the work platform 11 ranges from 64 degrees to 66 degrees. Preferably, the angle between the second stamping surface 3212 and the work platform 11 is 65 degrees. In another embodiment, the angle between the second stamping surface 3212 and the work platform 11 may also be 64 degrees or 66 degrees. The angle between the third stamping surface 3213 and the work platform 11 ranges from 83 degrees to 85 degrees. Preferably, the angle between the third stamping surface 3213 and the work platform 11 is 84 degrees. In another embodiment, the angle between the third stamping surface 3213 and the work platform 11 may also be 83 degrees or 85 degrees. The bottom of the connecting assembly 31 is provided with an auxiliary pressing surface, which is parallel to the working platform 11. Since the angle between the first stamping surface 3211 and the working platform 11 is only 5 degrees, it can be equivalent to being parallel to the working platform 11 in actual work. In this case, the auxiliary pressing surface can be set flush with the first stamping surface 3211 to increase the flattening area of the buckle 43 and enhance the flattening effect.
[0046] The stamping surfaces are connected by arc-shaped transitions, which reduces the sense of jamming during stamping and further improves the smoothness of stamping.
