[0026] Reference Figures 1 to 4 This application provides a punching die for an elliptical cookware, comprising: a lower template 100; two die inserts 200, arranged at intervals on the lower template 100, the top of the die insert 200 having a first arc surface 210; a positioning die 300, fixedly fitted onto the die insert 200, the positioning die 300 having an mounting surface 310 abutting against the lower template 100, the outer side of the positioning die 300 having a second arc surface 320, the second arc surface 320 being an elliptical arc surface, the second arc surface 320 cooperating with the first arc surface 210 to fit against the elliptical cookware 500, and the end face of the positioning die 300 having an abutting surface 330 abutting against the rim of the elliptical cookware 500.
[0027] By providing a second arc surface 320 on the outer side of the positioning jig 300, the second arc surface 320 being an elliptical arc surface, and the end face of the positioning jig 300 having an abutment surface 330, when the elliptical pot 500 is placed on the positioning jig 300, the first arc surface 210 and the second arc surface 320 fit together with the inner wall of the elliptical pot 500, and the rim of the elliptical pot 500 abuts against the abutment surface 330. At this time, precise positioning of the elliptical pot 500 is achieved, reducing the difficulty of punching and improving production efficiency. At the same time, the rotational freedom of the elliptical pot 500 is restricted, making the punching height stable and improving the punching accuracy. By providing two concave die inserts 200, they can cooperate with two punches 410 to punch, thereby completing the processing of two punches at one time, improving production efficiency and punching accuracy.
[0028] Reference Figures 1 to 4 In this embodiment, the positioning tire 300 is a one-piece molded structure, and a second arc surface 320 and an abutment surface 330 are formed through subsequent processing. It should be noted that the positioning tire 300 can also be configured as a split structure, that is, the positioning tire 300 includes a positioning tire 300 body and a positioning plate. The positioning tire 300 body is provided with the second arc surface 320, and the positioning plate is fixed to one side of the positioning tire 300 body by screws. The side of the positioning plate facing the positioning tire 300 body forms the abutment surface 330. In this case, the production and processing can be simplified and the production efficiency can be improved.
[0029] It is conceivable that the contact surface 330 is provided with clearances 340 to facilitate the quick placement and removal of the oval cookware 500 by operators, and to allow workers to safely and stably support the oval cookware 500 during punching, thus simplifying operation and improving production efficiency. Two sets of clearances 340 are provided, each corresponding to the major and minor axes of the oval cookware 500 respectively. Each set has two clearances 340, arranged opposite each other to ensure the stability of the oval cookware 500 and improve product quality.
[0030] Reference Figures 1 to 4 It is easy to understand that the positioning jig 300 is provided with a fixing hole 350, and a fastener 360 is provided in the fixing hole 350. The fastener 360 is connected to the die insert 200. The fastener 360 is a locking screw. Specifically, the positioning jig 300 is fitted onto the die insert 200, so that the mounting surface 310 abuts against the lower base plate. Then, the fastener 360 is inserted through the fixing hole 350 and connected to the die insert 200, thereby achieving the installation and fixation of the positioning jig 300. This allows for easy assembly and disassembly of the positioning jig 300, making operation simpler and improving production efficiency.
[0031] It should be noted that the positioning tire 300 can also be directly fixed to the lower base plate with screws, and this application does not limit this.
[0032] Reference Figures 1 to 3 Furthermore, the lower template 100 is provided with a first fixing plate 110, and the die insert 200 is disposed on the first fixing plate 110, with its mounting surface 310 abutting against the first fixing plate 110. Specifically, the die insert 200 is fixedly inserted into the first fixing plate 110, and then the first fixing plate 110 is fixed to the lower base plate by screws. At this time, the mounting surface 310 of the positioning jig 300 abuts against the first fixing plate 110. The first fixing plate 110 is provided with a first pin hole, and the lower template 100 is provided with a second pin hole. The first pin hole and the second pin hole are connected by a pin 120, which facilitates the positioning and installation of the first fixing plate 110 and the lower template 100.
[0033] Reference Figures 1 to 3 In some embodiments of this application, the punching die for elliptical cookware further includes an upper template 400, on which a punch 410 is provided. The die insert 200 has a relief groove 220, with the punch 410 located directly above the relief groove 220. The upper template 400 is mounted on a punch press, so that the punch 410 corresponds to the relief groove 220, thereby enabling punching. Further, the upper template 400 is provided with a second fixing plate 420, on which the punch 410 is disposed. Specifically, the second fixing plate 420 is connected to the upper template 400 by screws, allowing for detachable connection between the second fixing plate 420 and the upper template 400. This facilitates the replacement of punches 410 of different specifications, improving operational stability and reliability.
[0034] It is conceivable that the second fixing plate 420 is equipped with a ejector spring rubber 430, which is fitted onto the punch 410. The ejector spring rubber 430 is used for pressing and ejecting material during punching, and can also play a certain buffering role, improving the protection of the oval cookware 500. Optionally, the ejector spring rubber 430 is a polyurethane product. It is easy to understand that the top of the upper template 400 is provided with a die handle 440, which is used to connect the punch press to facilitate the installation of the upper template 400. The structure is simple and the operation is convenient.
[0035] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
