[0023] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, the double-conical gasket involved in this embodiment contains two flanged holes, which are located on the longitudinal center line of the gasket. The flanged holes are conical with an angle of 109.2° and a thickness of 3.6 mm. The gasket has an elliptical structure with a thickness of 1.2 mm.

[0025] In view of the above problems of low machining efficiency and difficult size control of double cone gaskets, Figures 2 to 8As shown, this embodiment provides a double-cone gasket pressing device, including a punch assembly, a die assembly, and a push rod 7. The punch assembly is placed above the die assembly, and the double-cone gasket blank 10 is placed between the punch assembly and the die assembly. The push rod 7 penetrates into the die assembly and can move freely up and down. The double-cone gasket can be quickly taken out by using the push rod.

[0026] In this embodiment, the punch assembly includes a punch seat 1 and a punch 2. The punch 2 is placed in the punch seat 1 and fixed by a hexagon socket screw Ⅰ3 to form a whole. Specifically, the punch seat 1 is provided with two mold mounting grooves Ⅰ11, and the bottom of the mold mounting groove Ⅰ11 is connected with a threaded fixing hole Ⅰ12. The punch 2 is provided with a mounting portion Ⅰ21 and a pressing portion Ⅰ22. The mounting portion Ⅰ21 is provided with a threaded hole 23. The mounting portion Ⅰ21 is placed in the corresponding mold mounting groove Ⅰ11 and is fixedly connected by the threaded hole 23 and the threaded fixing hole Ⅰ12. The working surface 221 of the pressing portion Ⅰ22 matches the shape of the flanging hole of the double cone gasket.

[0027] In this embodiment, the die assembly includes a die seat 4 and a die 5. The die 5 is placed in the die seat 4 and fixed by a hexagon socket screw Ⅱ6 to form a whole. Specifically, two mold mounting grooves Ⅱ41 are provided on the die seat 4, and a threaded fixing hole Ⅱ42 is connected to the bottom of the mold mounting groove Ⅱ41. A top material hole is provided at the bottom of the die seat 4, and a top material rod 7 that can move up and down is provided in the top material hole. The die 5 is provided with a mounting part Ⅱ51 and a pressing part Ⅱ52. A threaded hole 53 is provided on the mounting part Ⅱ51. The mounting part Ⅱ51 is placed in the corresponding mold mounting groove Ⅱ41 and is fixedly connected by the threaded hole 53 and the threaded fixing hole Ⅱ42. The working surface 521 of the pressing part Ⅱ52 matches the shape of the flanging hole of the double cone gasket.

[0028] The working principle of the above structure:

[0029] The first step is to assemble the punch assembly, install the punch 2 into the punch seat 1, and tighten it on the back with the hexagon socket screw Ⅰ3;

[0030] The second step is to assemble the die assembly, install the die 5 into the die seat 4, and tighten it on the back with the hexagon socket screw II 6;

[0031] The third step is to install the ejector rod 7 into the die 5;

[0032] The fourth step is to magnetically attach the assembled punch assembly and die assembly to the upper and lower end surfaces of the four-column hydraulic press and align them;

[0033] The fifth step is to load the double-cone gasket blank 10, start the four-column hydraulic press, and move the punch 2 downward with the equipment so that the punch 2 presses the double-cone gasket blank 10, and the punch 2 contacts the die 5. When the punch 2 and the die 5 cannot move up and down relatively, a pressing cycle is completed, and the ejector rod 7 is pushed to take out the gasket and detect the size of the gasket.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
