[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 3 This invention provides a technical solution: a stamping device for automotive sunroof sheet metal parts, including an upper template 1 and a lower template 2. The upper template 1 and the lower template 2 are respectively installed on an external punch press. The upper template 1 is provided with a punching part 3, and a positioning frame 4 is provided on the outer side of the punching part 3. The positioning frame 4 is fixedly installed on the upper template 1. A forming part 5 is provided directly below the punching part 3. The forming part 5 and the punching part 3 are stamped into shape under the pressure of the punch press. The forming part 5 is divided into two parts and the two parts are connected by an elastic rod 6. A pad 7 is provided below the forming part 5, and a support plate 8 is provided below the pad 7. The support plate 8 is connected to the lower template 2 by a support column 9. An auxiliary part removal component 10 is provided in the pad 7 and the support plate 8. The auxiliary part removal component 10 is used to assist the operator in removing the sunroof sheet metal part from the forming part 5. The forming part 5 is set in a concave shape to better fit the contour of the car roof. The main forming part is set in the forming part 5 so that the stamped sheet metal part can remain in the lower die part.

[0024] The bottom of the positioning frame 4 is connected to the upper template 1 through a pad. The positioning frame 4 is higher than the punching part 3. The working surface of the positioning frame 4 is an inclined surface. Through the cooperation of the inclined surface of the positioning frame 4 and the inclined surface on the forming part 5, the two forming parts 5 can be wedged tightly. Since it is wedged by the positioning frame 4 of the upper mold part, the accuracy of the punching part 3 and the forming part 5 can be guaranteed, thereby improving the stamping accuracy of the sheet metal parts.

[0025] The forming part 5 has a working surface corresponding to the inclined surface of the positioning frame 4. The forming part 5 has a guide bar 51 below it. The guide bar 51 can slide freely in the pad 7. This guide bar 51 can provide positioning for the forming part 5 so that the lateral position of the forming part 5 will not move.

[0026] The auxiliary part removal component 10 includes an air passage assembly 101, a sealing pad 102, several air nozzles 103, and an air jet protrusion 104. The air passage assembly 101 is installed on the lower surface of the upper template 1. The sealing pad 102 is located directly below the air passage assembly 101 and is installed in a corresponding groove on the pad 7. The lower part of the sealing pad 102 is connected to the air passage 105 located on the pad 7 and the support plate 8. The end of the air passage 105 is connected to all the air nozzles 103. The air nozzles 103 have air jet protrusions 104 at their air outlets. The air jet protrusions 104 have slits for airflow to be ejected. The air passage assembly 101 blows air into the air nozzles 103. After the two forming parts 5 are opened, air can be blown into the forming parts 5 through the air jet protrusions 104, which facilitates the loosening of the sheet metal parts in the forming parts 5 and provides convenience for removing the sheet metal parts.

[0027] The sealing pad 102 is provided with multiple vent holes 1021, so that the air in the air passage assembly 101 can be ejected normally through the sealing pad 102.

[0028] The air passage assembly 101 includes a fixed base 1011 and an extended air nozzle 1012. The fixed base 1011 is fixed on the upper template 1, and the extended air nozzle 1012 is installed inside the fixed base 1011. An air valve 1013 communicating with an external air pump is provided on the outer side of the fixed base 1011. An air passage communicating with the air valve 1013 on the fixed base 1011 is provided inside the extended air nozzle 1012. Air pumped out from the external air pump is introduced into the extended air nozzle 1012 through the air valve 1013, and then flows into the sealing pad 102 through the extended air nozzle 1012, and finally acts on the molding part 5.

[0029] The working principle is as follows: When in use, first install all the components correctly, then put the sheet metal part into the forming part 5, and control the upper mold part to press down through the punch press. During the pressing process, the positioning frame 4 will close the two parts of the forming part 5, and at the same time, the extended air nozzle 1012 will compress the sealing soft pad 102. After forming, the upper mold part is lifted. At this time, the sealing frame 4 will no longer squeeze the forming part 5, and the forming part 5 will slowly separate. At the same time, the extended air nozzle 1012 blows air into the sealing soft pad 102. The air will eventually be blown into the forming part 5 by the air jet boss 104, causing the sheet metal part to loosen in the forming part. As the upper mold part continues to rise, the extended air nozzle 1012 will detach from the sealing soft pad 102, and the air will no longer be ejected. The forming part 5 will separate to the maximum distance, and the sheet metal part will be completely separated from the forming part 5, making it easy to remove the sheet metal part.

[0030] Based on the above, the present invention can ensure that the stamped sheet metal part remains in the lower die by setting the concave forming part. After stamping is completed, the forming parts on both sides will separate to prevent the stamped sheet metal part from getting stuck in the forming part.

[0031] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
