Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a 65Mn material hinge bud stamping die. Background Technology

[0002] 65Mn material usually refers to a high-quality carbon structural steel with a high manganese content, mainly used to manufacture small springs and other mechanical parts. Hinge budding refers to a structure in hardware stamping die design where a flange is formed at the edge of a hole through a budding process.

[0003] Currently, most existing stamping dies directly punch holes in the product and then perform burring. This method of burring can easily lead to cracking and detachment, thus affecting the stamping effect of the stamping die. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the use of existing stamping dies, most of them directly punch holes in the product and then perform budding. This method of budding is prone to cracking and falling off, thus affecting the stamping effect of the stamping die. Therefore, a 65Mn material hinge budding stamping die is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hinge drawing stamping die for 65Mn material includes an upper die assembly, a lower die assembly, and a product body. The upper die assembly includes an upper die base, an upper pad plate fixedly connected to the bottom of the upper die base, an upper clamping plate fixedly connected to the bottom of the upper pad plate, a stop plate at the bottom of the upper clamping plate, and a stripper plate at the bottom of the stop plate. A punching punch and a embossing punch are fixedly inserted into the bottom of the upper clamping plate, with the bottom ends of the punching punch and the embossing punch passing through the stop plate and the stripper plate. The lower die assembly includes a lower die base, a lower pad plate fixedly connected to the top of the lower die base, a lower template plate fixedly connected to the top of the lower pad plate, and the lower template plate located below the stripper plate. A die insert block is fixedly connected to the top of the lower die base, with the top of the die insert block passing through the lower pad plate and the lower template plate. The product body is placed on top of the die insert block.

[0007] Furthermore, multiple guide sleeves are fixedly connected to the top of the lower mold base.

[0008] Furthermore, the bottom of the upper mold base is fixedly connected with multiple guide pillars, and the bottom ends of the guide pillars are slidably inserted into the guide sleeve.

[0009] Furthermore, a nitrogen spring is fixedly connected to the bottom of the upper mold base, and the bottom end of the nitrogen spring passes through the upper pad, the upper clamping plate and the stop plate and is fixedly connected to the stripper plate.

[0010] Furthermore, the product body is located between the stripper plate and the lower template.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The punch press moves downward, causing the punching punch to move downward. The punching punch and the die block cooperate to press a protrusion onto the product body. Then, the punch press moves downward, causing the punching punch to move downward, thereby punching a hole in the protrusion and preventing breakage and detachment.

[0013] 2. Driven by the punch press, the upper die holder, upper pad, upper clamping plate, stop plate and stripper plate move downward, so that the stripper plate presses on the product body, thereby fixing the product body so that it can be operated on in the future. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3A 65Mn material hinge bud stamping die includes an upper die assembly, a lower die assembly, and a product body 10. The upper die assembly includes an upper die base 1, an upper pad 2 fixed to the bottom of the upper die base 1 by bolts, an upper clamping plate 3 fixed to the bottom of the upper pad 2 by bolts, a stop plate 4 at the bottom of the upper clamping plate 3, and a stripper plate 5 at the bottom of the stop plate 4. The stripper plate 5 is pressed onto the product body 10 by the action of the punch press, thereby fixing the product body 10. A punching punch 13 and a punching punch 14 are fixedly inserted into the bottom of the upper clamping plate 3. The punch press moves downward, thereby driving the punching punch 13 to move downward, and the punching punch 13 and the die insert 9 cooperate to press out a protrusion on the product body 10. The bottom ends of the punching punch 13 and the punching punch 14 pass through the stop plate 4 and the stripper plate 5. The punch press moves downward, driving the punching punch 14 to move downward, thereby punching a hole in the protrusion.

[0021] The lower mold assembly includes a lower mold base 8, a lower pad 7 fixed to the top of the lower mold base 8 by bolts, a lower template 6 fixed to the top of the lower pad 7 by bolts, the lower template 6 being located below the stripper plate 5, multiple guide sleeves 11 welded to the top of the lower mold base 8, multiple guide pillars 12 welded to the bottom of the upper mold base 1, the bottom ends of the guide pillars 12 slidingly inserted into the guide sleeves 11, thereby guiding the movement of the upper mold assembly and improving the stability of the movement of the upper mold assembly, a cavity mold insert 9 for placing the product body 10 fixed to the top of the lower mold base 8 by bolts, the top of the cavity mold insert 9 passing through the lower pad 7 and the lower template 6, and the product body 10 being placed on the top of the cavity mold insert 9.

[0022] A nitrogen spring 15 is fixed to the bottom of the upper mold base 1 by bolts. The bottom end of the nitrogen spring 15 passes through the upper pad 2, the upper clamping plate 3 and the stop plate 4 and is fixedly connected to the stripper plate 5. The nitrogen spring 15 pushes the stripper plate 5 to move downward, thereby causing the punch to detach from the product body 10. The product body 10 is located between the stripper plate 5 and the lower mold plate 6.

[0023] The working principle of this embodiment is as follows: In use, firstly, the product body 10 is placed on the die insert 9. Then, the punch provides downward force, and under the drive of the punch, the upper die holder 1, upper pad 2, upper clamping plate 3, stop plate 4, and stripper plate 5 move downward, so that the stripper plate 5 presses on the product body 10, thereby fixing the product body 10. The punch continues to move downward, thereby driving the punching punch 13 to move downward, and then the punching punch 13 and the die insert 9 cooperate to press out a protrusion on the product body 10. Then, the punch moves upward and pushes the product body 10 forward one step. Next, the punch moves downward and drives the punching punch 14 to move downward, thereby punching a hole in the protrusion. Then, the punch moves upward and pushes the stripper plate 5 downward through the nitrogen spring 15, thereby causing the punch to detach from the product body 10, completing one cycle.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
