Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 5 , a bottom pressing machine for cast iron cookware, which includes a frame device for supporting and pressing the bottom of the cast iron cookware to form, and further includes a limiting device installed on the frame device for the cast iron cookware to penetrate up and down. A supporting device for upwardly supporting the bottom of the cast iron cookware to form is arranged below the limiting device.

[0025] In this embodiment: The frame device includes a frame body 101. A positioning groove 102 is arranged in the frame body 101. A fixing frame 103 is arranged on the frame body 101. The fixing frame 103 and the frame body 101 are welded together. A first cylinder 104 is installed at the top of the fixing frame 103. A pressing plate 105 is installed at the bottom telescopic end of the first cylinder 104. The pressing plate 105 is circular. The frame body 101 supports the first cylinder 104 to expand and contract through the fixing frame 103 to push the pressing plate 105 to move up and down.

[0026] In this embodiment: The limiting device includes a forming die 201. The forming die 201 is square. A supporting edge 203 is arranged at the bottom of the forming die 201. A plurality of mounting holes 205 are evenly distributed on the supporting edge 203. A positioning table 204 is arranged below the supporting edge 203. A forming cavity 202 is arranged in the middle of the forming die 201. The forming cavity 202 is circular. The forming cavity 202 penetrates the forming die 201 from top to bottom. The supporting edge 203, the positioning table 204 and the forming die 201 are integrally formed. The forming die 201 is positioned by inserting the positioning table 204 into the positioning groove 102 on the frame body 101, and the forming die 201 is fixed on the frame body 101 by passing a stud through the mounting holes 205 on the supporting edge 203. The cast iron cookware with the bottom pressed passes out from the bottom of the forming cavity 202.

[0027] In this embodiment: The supporting device includes a second cylinder 301. A limiting plate 302 is installed at the top telescopic end of the second cylinder 301. A supporting table 303 is arranged on the limiting plate 302. The limiting plate 302 is square. The supporting table 303 is circular.
