[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment

[0021] Given by Figures 1-3 There is a trimming die for forgings, which includes a workbench 1, guide columns 2 and a top plate 3. The workbench 1 is connected between the guide columns 2 and the top plate 3. In the middle of the upper end surface of the workbench 1, there is a placement cavity 11. A cleaning component is arranged in the middle of the workbench 1. A hydraulic cylinder 4 is movably installed on the upper end surface of the top plate 3. One end of the piston rod of the hydraulic cylinder 4 is provided with a cutting component;

[0022] The cutting component includes a lifting plate 5 and a cutting knife 6. The cutting knife 6 is assembled with the lifting plate 5, and there are multiple cutting knives 6 which are arranged in a circle. In the middle of the lower end surface of the lifting plate 5, there is a pressing plate 7 connected. The cleaning component includes a cutting groove 61 and multiple push plates 62. The cutting groove 61 is opened on the upper end surface of the workbench 1, and the cutting groove 61 is arranged along the edge of the placement cavity 11 in a circle and corresponds to the cutting knife 6.

[0023] In this embodiment, by arranging the placement cavity 11 in the middle of the workbench 1 and opening the cutting groove 61 in a circle, the push plate 62 is slidably connected in the cutting groove 61, and the cutting knife 6 is assembled on the lower end surface of the lifting plate 5. The forging is placed in the placement cavity 11, and the hydraulic cylinder 4 drives the lifting plate 5 to descend, driving the cutting knife 6 to descend and slide along the inner side surface of the cutting groove 61 for cutting. With the multiple cutting knives 6 arranged in a circle, the excess corners and edges of the forging are cut. When the cutting knife 6 cuts, it will push the push plate 62 to descend and compress the first spring 63, and the cut edge materials will fall into the cutting groove 61 accordingly. When the cutting knife 6 moves upward and disengages from the push plate 62, the push plate 62 will push the corner materials out of the cutting groove 61 under the action of the rebounding force of the first spring 63. The air cylinder 8 drives the scraping plate 9 to slide on the upper end surface of the workbench 1, so as to scrape the pushed-out corner materials off the upper end surface of the workbench 1, realizing the rapid cleaning of the corner materials accumulated in the cutting groove 61 and improving the cleaning efficiency and trimming efficiency.

[0024] It should be noted that, given by Figure 2 and Figure 3 it can be seen that the thickness of the cutting knife 6 is less than the width of the cutting groove 61, so that when the cutting knife 6 slides along the inner side wall of the cutting groove 61 for cutting, the excess corner materials will fall into the cutting groove 61. At the same time, the material of the cutting knife 6 in the figure can refer to high heat-resistant die steels such as 8566 die steel and LG die steel or high-speed steel, etc., so that the adhesion of the corner materials can be reduced during cutting.

[0025] Specifically, please refer to Figure 1 and Figure 3, in order to improve the cleaning efficiency and trimming efficiency, the push plate 62 is slidably connected to the cutting groove 61, and a plurality of first springs 63 are movably installed between the push plate 62 and the bottom of the cutting groove 61. The cutting groove 61 communicates with the placement cavity 11, and the inner side wall of the cutting groove 61 and the outer side wall of the placement cavity 11 are on the same plane, which is convenient for more complete cutting. The cleaning assembly further includes a cylinder 8 and a scraper 9. The cylinder 8 is movably installed on one side of the upper end surface of the workbench 1, the scraper 9 is movably installed at one end of the piston rod of the cylinder 8, and the scraper 9 is slidably connected to the upper end surface of the workbench 1.

[0026] In this embodiment, by setting the push plate 62 to be slidably connected to the cutting groove 61, and the inner side wall of the cutting groove 61 and the outer side wall of the placement cavity 11 are on the same plane, and cooperating with the first spring 63 arranged between the push plate 62 and the bottom of the cutting groove 61, when the cutting knife 6 trims the edge, the cutting knife 6 pushes the push plate 62 to slide along the inner wall of the cutting groove 61 and compresses the first spring 63. After the cutting is completed, the first spring 63 pushes the push plate 62 back to its original position and pushes out the trimmed edge material from the cutting groove 61, preventing the cutting groove 61 from being blocked. At the same time, by driving the scraper 9 to slide on the upper end surface of the workbench 1 through the cylinder 8, the pushed-out edge material is scraped off, improving the cleaning efficiency and trimming efficiency.

[0027] Specifically, please refer to Figure 2 , in order to increase the stability of cutting, the lifting plate 5 is provided with a groove and slidably connected to the guide post 2 for the cutting assembly to cut stably. A plurality of second springs 72 are movably installed between the lower end surface of the lifting plate 5 and the pressing plate 7. A silicone pad 71 is provided on the lower end surface of the pressing plate 7 for fitting and pressing the upper surface of the forging to prevent the surface of the forging from being worn during pressing.

[0028] In this embodiment, by setting the lifting plate 5 to be slidably connected to the guide post 2 and arranging the pressing plate 7 on the lower end surface of the lifting plate 5 through the second spring 72, when cutting, the guiding of the guide post 2 increases the stability of the lifting plate 5 during lifting. At the same time, when lifting and cutting, the silicone pad 71 fits the surface of the forging and compresses the second spring 72, and the rebounding force of the second spring 72 pushes the pressing plate 7 to press the surface of the forging, preventing the forging from shifting during cutting, affecting the cutting efficiency and quality, and thus increasing the stability of cutting.

[0029] The working principle of the above embodiment is:

[0030] A placement cavity 11 is arranged in the middle of the workbench 1, and a cutting groove 61 is circumferentially opened. A push plate 62 is slidably connected in the cutting groove 61. A cutting knife 6 is assembled to the lower end surface of the lifting plate 5. The forging is placed in the placement cavity 11. The hydraulic cylinder 4 drives the lifting plate 5 to descend, driving the cutting knife 6 to descend and slide along the inner side surface of the cutting groove 61 for cutting. With multiple cutting knives 6 arranged circumferentially, the excess corners and edges of the forging are cut. When the cutting knife 6 cuts, it will push the push plate 62 to descend and compress the first spring 63, and the cut edge materials will fall into the cutting groove 61 accordingly. When the cutting knife 6 moves upward and disengages from the push plate 62, the push plate 62 will push the corner and edge materials out of the cutting groove 61 under the action of the rebounding force of the first spring 63. The air cylinder 8 drives the scraping plate 9 to slide on the upper end surface of the workbench 1, so as to scrape the pushed-out corner and edge materials off the upper end surface of the workbench 1, realizing the rapid cleaning of the corner and edge materials accumulated in the cutting groove 61, and improving the cleaning efficiency and the edge cutting efficiency.
