In addition, the method implementation may include additional steps and / or omit the steps shown. The scope of the present utility model is not limited in this respect.

[0018] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "connected" may be directly connected or indirectly connected through intermediate components (elements). The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0019] Please combine Figure 1 and Figure 2 The utility model relates to an easy-pull lid punching machine, which adds a lubricant at the position where the lid body and the rivet are combined. The lubricant is mainly an oily lubricating material (lubricating oil), such as pull ring oil or paraffin. When the lubricated lid passes through the mold, the mold is lubricated to prevent the mold from wearing the rivet and causing spots, thereby improving the yield rate.

[0020] The easy-open lid punching machine comprises a punching machine body and a lubricating device 40 connected to the punching machine body, wherein the lubricating device is used to add lubricant to the rivet position when the punching machine is punching. The punching machine body comprises a lower platform 10, a cover conveying belt 20 arranged on the lower platform, and an upper slider 30 arranged above the lower platform and capable of sliding up and down, wherein the cover conveying belt 20 is provided with a positioning hole for accommodating a cover sheet. The lubricating device 40 comprises a lubricating conduit 41 for conveying lubricating oil and a felt 42 arranged at the output end of the lubricating conduit and capable of absorbing lubricating oil, wherein the lubricating conduit is arranged directly above the cover conveying belt and enables the felt to contact the cover sheet in the positioning hole when the upper slider moves downward.

[0021] In one embodiment, the cover conveying belt 20 is provided with at least two rows of positioning holes, the number of the lubrication ducts is arranged in one-to-one correspondence with the number of rows of positioning holes, and the output end of each lubrication duct is provided with the felt. By providing at least two rows of positioning holes, multiple covers can be conveyed synchronously, thereby completing stamping production and improving production efficiency.

[0022] In one embodiment, the lubrication device further comprises an oil distributor 45 having an oil inlet hole and an oil outlet hole whose number is the same as the lubrication duct, and the oil inlet hole is connected to an external oil supply device via an oil inlet duct 451 .

[0023] In one embodiment, the lubrication device further includes a flow regulating unit 46, which is connected to the oil distributor 45 and is used to regulate the flow of the lubricating oil in each lubrication duct.

[0024] In one embodiment, the lubrication device includes an L-shaped mounting plate 43, one side of the L-shaped mounting plate 43 is fixed to the upper slider 30, and the other side is provided with a mounting hole, the felt 42 is connected to the lubrication duct 41 through a hollow threaded tube 44, and the threaded tube 44 is passed through the mounting hole.

[0025] In one of the embodiments, the L-shaped mounting plate 43 is provided with a limit nut on both sides, which is threadedly connected to the threaded tube 44. The limit nut is tightly attached to the mounting plate. By setting the limit nut and the threaded tube in connection, the position of the felt 42 in the up and down directions can be controlled to adapt to the lubrication of covers of different sizes.

[0026] When the cover passes through the punch press, in order to ensure that the pull ring is riveted to a fixed position on the cover surface, the cover is usually fixed. In this embodiment, a cover transfer belt plus vacuum adsorption is adopted. In one of the implementations, a vacuum chamber connected to the positioning hole is provided corresponding to the positioning hole under the cover transfer belt, and the vacuum chamber is connected to a vacuum pump. When the cover body falls into the positioning hole, the vacuum chamber is turned into a vacuum by the vacuum pump to provide negative pressure, so as to firmly adsorb the cover body to prevent it from rotating when the pull ring is riveted to the cover body.

[0027] The working principle of the utility model is:

[0028] After the lids pass through the lid separation wheel, each lid falls into the positioning hole of the lid transfer belt and is brought into the mold. Since there is a vacuum chamber under the belt, the vacuum pump provides negative pressure to firmly adsorb the easy-open lid on the lid transfer belt, so that the easy-open lid will not rotate in the belt hole. Since the lubrication device is fixed on the slider of the punch press, the lubrication duct is aligned with the rivet position on the lid surface. With each punch press, the felt on the lubrication duct applies a small amount of paraffin or ring-pulling oil to the rivet position. When the lids coated with lubricant pass through the mold again, the mold is lubricated, so it is not easy to have spots when riveting, thereby improving the yield rate.

[0029] The above description is only a preferred embodiment of the utility model and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the utility model is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the above utility model.
