Description

Technical Field

[0001] This utility model belongs to the field of ring forging flange punching technology, specifically relating to a replaceable punching disc for ring forging flange punching. Background Technology

[0002] A punching stencil for ring forging flanges is a piece of equipment used in the ring forging flange production process. It is mainly used to punch holes in the flange to create the required openings, such as mounting holes and drainage holes. The punching stencil is typically used in conjunction with a punch press or hydraulic press, using a punch to press the flange material to form the specified hole diameter and spacing.

[0003] While existing replaceable slugs allow for the removal and replacement of the core to accommodate slug holes of different diameters, the core is often horizontally attached to the platform. When removing the core, its surface is relatively smooth with few pressure points, making it difficult to remove the core easily and thus impractical. Utility Model Content

[0004] The purpose of this invention is to provide a replaceable slotted disc for punching ring forging flanges, which can use an auxiliary disc-removing assembly to lift the replaceable disc core upwards, so that the replaceable disc core protrudes to the upper side of the annular disc for easy removal.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A replaceable punching tray for ring forging flanges includes an annular disc, a replaceable core is provided on the inner side of the annular disc, a material discharge hole is opened at the center of the top surface of the replaceable core, a base plate is provided on the lower side of the annular disc, a support plate is fixedly connected to the top surface of the base plate, the support plate has a C-shaped structure, a plurality of side ribs are fixedly connected to the side wall of the support plate, the side ribs and the support plate are both fixedly connected to the bottom surface of the annular disc, the replaceable core is placed on the top surface of the support plate and the side ribs, a guide plate is fixedly connected to the inner side of the support plate below the material discharge hole, the guide plate extends to the outer side of the support plate, the guide plate has a downward inclined structure, and an auxiliary tray-retrieving assembly is provided in the inner cavity of the support plate near the rear side.

[0007] The auxiliary tray retrieval assembly includes a through groove opened on the side wall of the support plate near the rear side. A top plate is provided in the through groove. The top plate has a Z-shaped structure. A rotating shaft is fixedly connected to the front and rear side walls of the top plate, respectively. The other end of the rotating shaft is rotatably connected to the side wall of the through groove. A torsion spring is installed on the side wall of the rotating shaft.

[0020] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4As shown, a replaceable punching tray for ring forging flanges includes an annular disc 1, a replaceable core 2 is provided on the inner side of the annular disc 1, a material discharge hole 3 is opened at the center of the top surface of the replaceable core 2, a base plate 6 is provided on the lower side of the annular disc 1, a support plate 4 is fixedly connected to the top surface of the base plate 6, the support plate 4 has a C-shaped structure, a number of side ribs 5 are fixedly connected to the side wall of the support plate 4, both the side ribs 5 and the support plate 4 are fixedly connected to the bottom surface of the annular disc 1, the replaceable core 2 is placed on the top surface of the support plate 4 and the side ribs 5, a guide plate 7 is fixedly connected to the inner side of the support plate 4 below the material discharge hole 3, the guide plate 7 extends to the outer side of the support plate 4, the guide plate 7 has a downward inclined structure, and an auxiliary tray-removing assembly is provided in the inner cavity of the support plate 4 near the rear side.

[0022] Specifically, there are several replaceable disc cores 2, and the outer diameter of each replaceable disc core 2 is the same. The diameter of the material discharge hole 3 on its surface is commonly 643mm-800mm. Users can choose to use them according to their punching needs.

[0023] like Figure 2 and Figure 4 As shown, the auxiliary tray-retrieving assembly includes a through groove 9 opened on the side wall of the support plate 4 near the rear side. A top plate 10 is provided in the through groove 9. The top plate 10 has a Z-shaped structure. A rotating shaft 11 is fixedly connected to the front and rear side walls of the top plate 10, respectively. The other end of the rotating shaft 11 is rotatably connected to the side wall of the through groove 9. A torsion spring 12 is installed on the side wall of the rotating shaft 11. One end of the top plate 10 extends to the rear side of the annular disk 1.

[0024] The top surface of the top plate 10 is located below the replaceable disc core 2 and is rotatably connected to several movable wheels 13.

[0025] An anti-slip plate 14 is fixedly connected to the top surface of the top plate 10 at the rear side of the annular disc 1. In addition, the anti-slip plate 14 is made of high-temperature resistant rubber, latex, plastic or metal, which can increase the friction with the operator's hand and ensure stability when pressing.

[0026] The top plate 10 in the auxiliary plate retrieval assembly operates on a seesaw principle. When one end is pressed down, the force of the pivot 11 causes the other end to tilt upward, allowing the replaceable plate core 2 to be easily removed. In addition, by setting multiple movable wheels 13, friction between the replaceable plate core 2 and the plate is reduced, making it easier to press the top plate 10 and reducing friction on the replaceable plate core 2, thus avoiding scratches on its surface.

[0027] like Figure 1 As shown, several mounting holes 15 are provided on the top surface of the base plate 6 near the edge. These mounting holes 15 facilitate the installation of the entire assembly on the stamping table; this installation method is a conventional structure and will not be described in detail in this design.

[0028] like Figure 1 As shown, two baffles 8 are fixedly connected to the top surface of the guide plate 7. By setting the baffles 8, a U-shaped structure can be formed between them and the guide plate 7, so that the material plate falling during stamping will not enter the inner side of the support plate 4, ensuring the smoothness of material discharge.

[0029] The working principle of this utility is as follows: First, the device is fixed on the stamping table through the mounting hole 15. Then, according to the punching process requirements, a suitable replacement disc core 2 with a suitable material leakage hole 3 is selected and placed inside the annular disc 1. It is supported by the support plate 4 and the side wing rib plate 5. The material plate generated during the stamping process falls from the material leakage hole 3 onto the guide plate 7. The inclined surface of the guide plate 7 is used to discharge the material plate.

[0030] When it is necessary to replace the replaceable disc core 2 with another specification, press the position of the anti-slip plate 14 on the back of the top plate 10, and the front side of the top plate 10 will be tilted upward through the pivot 11. The movable wheel 13 will contact the replaceable disc core 2, and the replaceable disc core 2 will be pushed upward, making the replaceable disc core 2 higher than the annular disc 1, so that the replaceable disc core 2 can be taken out. Then, release the top plate 10, and use the force of the torsion spring 12 to drive the top plate 10 to return to its original position, thereby completing the replacement of the replaceable disc core 2.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
