[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0025] Embodiment one: a key shape rotation axis is with shaping die, such as Figure 1 - Figure 4As shown, it comprises a supporting lower die 1, a supporting upper die 2, a supporting bottom plate 3, and an auxiliary groove 401 provided through the supporting lower die 1, a flow-through groove 4 provided through the supporting upper die 2, and a supporting groove 402 opened at the upper end of the supporting bottom plate 3. The auxiliary groove 401, the flow-through groove 4, and the supporting groove 402 are located at the same vertical position. The auxiliary groove 401 is inserted with a shaping supporting block 501. The flow-through groove 4 is inserted with a shaping block 5. An elastic connecting plate 14 is provided below the shaping supporting block 501 to elastically support. A pressing support 6 is provided at the upper end of the shaping block 5 to press support.

[0026] Firstly, the supporting lower die 1, the supporting upper die 2, the shaping supporting block 501, and the shaping block 5 are combined to limit the lower part, so that a key-shaped shaping space is formed in the middle part. After the product is placed in the shaping space, the supporting lower die 1 and the supporting upper die 2 are fastened to limit the product as a whole. Then, the shaping block 5 is moved to gradually contract the distance between the shaping block 5 and the shaping supporting block 501. Then, the shaping block 5 is continuously pressed to forcibly plastically deform the product as a whole by the shaping block 5 and the shaping supporting block 501. The product is stably shaped under the constraint of the shaping space and the continuous extrusion of the shaping block 5 and the shaping supporting block 501. Thus, the device can stably and accurately shape the product to improve the shaping effect on the product.

[0027] As shown in Figure 1 - Figure 4 The supporting lower die 1, the supporting upper die 2, the shaping supporting block 501, and the shaping block 5 form a shaping space. The upper end surface of the supporting lower die 1 is in contact with the lower end surface of the supporting upper die 2. The upper end surface of the shaping supporting block 501 is in contact with the lower end surface of the shaping block 5.

[0028] The use of the shaping space ensures the stability of shaping the product. Based on the mutual contact of the adjacent surfaces of the supporting lower die 1 and the supporting upper die 2 and the mutual contact of the adjacent surfaces of the shaping block 5 and the shaping supporting block 501, the shaping effect on the product is further improved, and the accuracy and stability of the device are improved.

[0029] As shown in Figure 1 - Figure 4 The supporting groove 402 is internally installed with at least two groups of elastic components 15. The elastic component 15 internally comprises a supporting cylinder, an extension rod, and a return spring. The extension rod is located in the middle of the return spring. The return spring is located in the supporting cylinder. The extension rod is in sliding connection with the supporting cylinder. The return spring and the extension rod are fixedly arranged on the lower end surface of the elastic connecting plate 14.

[0030] A positioning hole 16 is opened in the side edge of the elastic connecting plate 14. The positioning hole 16 is used for inserting with an external positioning rod. A guide groove is opened in the upper end surface of the supporting bottom plate 3 and the lower end surface of the supporting lower die 1. The guide groove is in communication with the positioning hole 16 when fastened. The positioning rod is inserted with the guide groove and the positioning hole 16.

[0031] Under the elastic action of the elastic component 15, when the elastic connecting plate 14 is subjected to pressure, when the elastic component 15 is pressed and contracted, based on the elastic action of the elastic component 15 itself, it can provide an upward force for the elastic connecting plate 14 and the shaping support block 501. Combined with the downward pressure of the device, it can use a combination of pressure in two directions on the product to improve the shaping strength of the product. In addition, with the combined use of the positioning hole 16 and the outer positioning rod, the position of the elastic connecting plate 14 can be positioned to ensure the accuracy of the position of the shaping support block 501 when the product is placed, thereby improving the accuracy of the use of the device.

[0032] Example 2: A shaping die for a key-shaped rotating shaft, such as Figure 1 - Figure 4 As shown, two sliding guide rods 7 are provided on the upper end surface of the supporting upper mold 2, and the pressing bracket 6 is simultaneously plugged into the two sliding guide rods 7. A limiting guide rod 8 is installed in the middle of the pressing bracket 6, and the limiting guide rod 8 is plugged into the pressing transmission rod 9. A positioning frame 10 is plugged into the middle of the pressing transmission rod 9, and a driving motor 13 is installed at the other end of the pressing transmission rod 9.

[0033] The lower half of the positioning frame 10 is connected to the support rail 12, and the positioning frame 10 is slidably set in the guide groove on the support rail 12, and a plurality of positioning holes are opened on the upper end surface of the support rail 12. The support rail 12 is connected to the positioning frame 11 through the positioning holes, and the positioning frame 10 is connected to the positioning frame 11.

[0034] The driving motor 13 is installed on the upper end surface of the supporting lower mold 1 , and the driving motor 13 is located at the midpoint of the pressing bracket 6 , and the pressing transmission rod 9 is connected to the output end of the driving motor 13 .

[0035] By starting the driving motor 13, it pushes one end of the pressing transmission rod 9 to move upward, and based on the fixed-point support of the positioning frame 10, the other end of the pressing transmission rod 9 moves downward under the limit of the limiting guide rod 8, and the pressing and pressing bracket 6 moves downward synchronously under the guidance of the sliding guide rods 7 on both sides, so that the shaping block 5 is pressed, and by adjusting the position of the positioning frame 11 on the support rail 12, the positioning frame 10 is driven to move synchronously, and the force point of the pressing transmission rod 9 can be adjusted, so that the ratio between the force applied to the lifted end of the pressing transmission rod 9 and the force applied to the pressed end of the pressing transmission rod 9 is adjusted, so that the same lifted force is converted to different degrees, and the pressing of the shaping block 5 is formed in a sequentially increasing manner, so that it can steadily shape the product and improve the stability and uniformity of the pressure on the product.

[0036] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
