[0055] The technical solution of the utility model is further described in conjunction with the following embodiments.
[0056] Example 1
[0057] A stamping and shaping device, such as Figures 1 to 4 As shown, an upper mold assembly 100, a molding assembly 200 for shaping the side of a product 400, and a lower pad 300 are provided. The molding assembly 200 is assembled on the upper surface of the lower pad 300, and the upper mold assembly 100 is movably abutted against the molding assembly 200;
[0058] The forming assembly 200 is provided with a plurality of shaping sliders 220 , a slider seat 210 and a supporting plate 250 . The slider seat 210 is assembled on the supporting plate 250 , and the shaping sliders 220 are slidably connected to the slider seat 210 .
[0059] Before the product 400 is shaped, a plurality of shaping sliders 220 protrude from the slider seat 210, such as Figure 5 ;
[0060] When the product 400 is shaped, the plurality of shaping sliders 220 are located inside the slider seat 210, and the plurality of shaping sliders 220 form a closed structure, and a shaping cavity 224 for shaping the side of the product 400 is formed inside the closed structure, such as Figure 6 .
[0061] It should be noted that the shaping sliders 220 of the utility model can be set to 2, 3, 4, 5, etc., as long as all the shaping sliders 220 can form a closed structure when the product 400 is shaped. This embodiment takes 4 shaping sliders 220 as an example to illustrate the utility model.
[0062] It should also be explained that the downward direction of the upper mold assembly 100 is defined as downward. During the downward movement of the upper mold assembly 100 of the utility model, multiple shaping sliders 220 are simultaneously driven to move downward. When the shaping slider 220 moves downward, the slider seat 210 restricts the multiple shaping sliders 220 to gather toward the center at the same time, thereby simultaneously squeezing and shaping the sides of the product 400, and the upper mold assembly 100 also squeezes the top surface of the product 400 during the downward movement. By squeezing the product 400 on the sides and the top surface, the shaping accuracy of the product 400 can be improved.
[0063] The shaping slider 220 is provided with a first sub-block 221 and a second sub-block 222, and the first sub-block 221 and the second sub-block 222 are integrally connected. Figure 7 ,in Figure 7The dotted area is the second sub-block 222. The first sub-block 221 and the second sub-block 222 are both slidably mounted on the slider seat 210. One wall of the first sub-block 221 forms a shaping cavity 224. The side wall of the second sub-block 222 is an inclined surface. The slider seat 210 is provided with a sliding groove 211 that matches the contour of the shaping slider 220. The angle between the inclined surface and the bottom surface of the second sub-block 222 is A, and there is 90°<A≤130°. Figure 8 The width of the first sub-block 221 is defined as B 1 , the width of the second sub-block 222 is defined as B 2 , there exists B 1 <B 2 ≤1.5B 1 ,like Fig. 9 .
[0064] It should be noted that the angle between the inclined surface and the bottom surface of the utility model can ensure that the shaping slider 220 smoothly enters and gathers along the slider seat 210, and the width range of the second sub-block 222 can prevent the shaping slider 220 from sliding along the corresponding track.
[0065] It should also be noted that the matching of the sliding groove 211 and the contour of the shaping slider 220 mentioned in the present invention refers to the matching of the shaping slider 220 to limit its movement within the corresponding trajectory while ensuring its smooth movement.
[0066] The shaping slider 220 is further provided with a guide rib 223 , and the guide rib 223 is integrally connected to the lower end of the second sub-block 222 .
[0067] The molding assembly 200 is also provided with a plurality of first springs 240, an assembly plate 230, a center column 260, a lower ejector pin 270 for demolding the molded product 400, and a second spring 280. The assembly plate 230 is assembled on the upper side of the support plate 250, the slider seat 210 is embedded in the assembly plate 230 and fixedly assembled with the support plate 250, one end of the first spring 240 is embedded in the support plate 250, the other end of the first spring 240 is fixed to the shaping slider 220, one end of the center column 260 is fixed to the support plate 250, and the other end of the center column 260 passes through the molding cavity 224. The lower ejector pin 270 is arranged inside the center column 260, and one end of the lower ejector pin 270 can be movably extended from the center column 260, one end of the second spring 280 is assembled on the lower pad 300, and one end of the second spring 280 is fixed to the bottom of the lower ejector pin 270.
[0068] When the product 400 is shaped, the product 400 is located in the gap between the outer surface of the central column 260 and the first sub-block 221 .
[0069] It should be noted that before the product 400 is shaped, the product 400 is directly placed on the upper end of the lower ejector 270. When the upper mold assembly 100 moves downward, the upper mold assembly 100 drives the lower ejector 270 and the product 400 to move downward as a whole, and at the same time the second spring 280 is compressed, and finally the product 400 is sleeved on the upper end of the center column 260; when the product 400 is shaped, the upper mold assembly 100 moves upward, the second spring 280 expands and contracts, and the lower ejector 270 pushes the product 400 upward, thereby separating the product 400 from the center column 260.
[0070] Because some products 400 have an inner R angle at the end of the product 400 to be shaped in the pre-treatment process, the stamping die of the prior art is not suitable for stamping the inner R angle into a right angle. In the stamping shaping device of the utility model, when the product 400 is shaped, the central column 260 supports the inside of the product 400, and the product 400 is squeezed in the gap between the outer surface of the central column 260 and the first sub-block 221 to form the final shape. Moreover, the surface of the central column 260 can stamp the inner R angle of the product 400 into a right angle.
[0071] The upper mold assembly 100 is provided with an upper pad 110, an upper clamping plate 120, a stripping plate 130, a third spring 140 and a guide column 160. The upper pad 110 is fixedly stacked on the upper clamping plate 120, and the upper clamping plate 120 and the stripping plate 130 are stacked and connected by the third spring 140. One end of the guide column 160 is fixedly assembled on the bottom surface of the upper pad 110, and the other end of the guide column 160 passes through the upper clamping plate 120 and the stripping plate 130 in sequence. The bottom surface of the stripping plate 130 is provided with a shaping groove 131 for shaping the top surface of the corresponding product 400, and the shaping groove 131 is located directly above the shaping cavity 224, as shown in FIG. Fig.10 .
[0072] It should be noted that the function of the guide column 160 is to guide the upper mold assembly 100 as a whole.
[0073] The supporting plate 250 and the assembly plate 230 are both provided with guide holes through which the guide pillars 160 penetrate; when the product 400 is being shaped, the other end of the guide pillars 160 is located inside the supporting plate 250 .
[0074] The upper mold assembly 100 is also provided with an upper guide sleeve 150, which is fixedly assembled inside the stripper plate 130, and the guide post 160 movably penetrates the upper guide sleeve 150. The molding assembly 200 is also provided with a lower guide sleeve 290, which is fixedly assembled in the guide hole of the assembly plate 230, and the guide post 160 movably penetrates the lower guide sleeve 290.
[0075] It should be noted that the function of the upper guide sleeve 150 and the lower guide sleeve 290 is to reduce the friction between the guide column 160 and the stripper plate 130 and the assembly plate 230 .
[0076] The punching and shaping device of the utility model can make the product 400 (such as Figure 11-13 ) is shaped into a product with a diameter of 25.300mm 400 (such as Figure 14-16 ), the diameter is reduced by 0.394%. After shaping, the inner R angle of the bottom of the product 400 (such as Fig.13 ) is rounded to a right angle (such as Fig.16 ), so the stamping shaping device can effectively improve the stamping accuracy and the accuracy of the product 400. Of course, the utility model can adjust the size of the shaping slider 220 and the center column 260 according to the size of the product 400 to shape different products 400 and requirements.
[0077] It should also be noted that the upper die assembly 100 and the forming assembly 200 of the punching and shaping device of the present invention are both composed of different individual parts, so when a part is damaged, only the corresponding part needs to be replaced, and the maintenance cost is low. For example, when a shaping slider 220 is damaged, only the shaping slider 220 needs to be removed from the slider seat 210 and replaced with a new shaping slider 220.
[0078] The punching and shaping device can improve the punching accuracy and the product 400 accuracy by providing multiple shaping slide blocks 220 and slide block seats 210. The punching and shaping device of the utility model has low maintenance cost, simple structure and low production cost.
[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
