[0054] Embodiment one

[0055] Referring to Figures 1-16 The embodiment discloses a frame forming die, which comprises a driving piece 10, a shaping module 20 and a base 30; the moving direction of the driving piece 10 relative to the base 30 is a first direction Z, and the moving direction of the shaping module 20 relative to the base 30 is perpendicular to the first direction, that is, each shaping module 20 moves in a plane perpendicular to the first direction (Z direction);

[0056] The base 30 is a fixed piece, mainly used for mounting the driving piece 10 and the shaping module 20, and the driving piece 10 and the shaping module 20 are both movable pieces and can move relative to the base 30;

[0057] like Figure 10 As shown, a plurality of second driving inclined surfaces 101 are formed on the upper part of the driving member 10. The second driving inclined surfaces 101 are inclined relative to the first direction. All the second driving inclined surfaces 101 are arranged around the outer periphery of the driving member 10. Specifically, all the second driving inclined surfaces 101 are arranged circumferentially around the axis of the driving member 10.

[0058] like Figure 9 As shown, the shaping module 20 includes a shaping part 201 and a push-pull part 202. The shaping part 201 includes a shaping surface 2011 and a connecting surface 2012. One end of the push-pull part 202 is connected to the connecting surface 2012 of the shaping part 201, and the other end is provided with a sliding surface 2021 that can slide along the driving member 10. The sliding surface 2021 includes a first driving inclined surface 20211. The first driving inclined surface 20211 of each shaping module 20 corresponds one-to-one with the second driving inclined surface 101. The first driving inclined surface 20211 of each shaping module 20 can slide along the corresponding second driving inclined surface 101.

[0059] The base 30 has a main sliding cavity 301 formed inside for the sliding of the driving component 10. A slot 302 is provided on the side wall of the base 30, and the slot 302 is connected to the main sliding cavity 301. Each slot 302 corresponds one-to-one with a push-pull portion 202 of the shaping module 20. Each push-pull portion 202 of the shaping module 20 can be slidably connected to its corresponding slot 302. The shaping surfaces 2011 of all the shaping modules 20 on the base 30 are arranged in a first shape; that is, connecting the shaping surfaces 2011 end-to-end can form a first shape. Figure 1 , Figure 4 and Figure 8 As shown, the shaping surfaces 2011 of all the shaping modules 20 on the base 30 form a rectangle;

[0060] The driving component 10 has a first position and a second position, see below. Figures 1-5 When the driving component 10 is in the first position, the first driving inclined surface 20211 of the shaping module 20 contacts the corresponding second driving inclined surface 101. When the driving component 10 switches from the first position to the second position, refer to... Figures 11-13 The shaping module 20 moves outward, and the first driving inclined surface 20211 of the shaping module 20 disengages from the corresponding second driving inclined surface 101.

[0061] The above structure allows the first driving inclined surface 20211 to slide relative to the corresponding second driving inclined surface 101 through the push-pull driving component 10, thereby allowing the shaping module 20 to move outward relative to the base 30. The moving shaping module 20 can push against the external blank, thereby causing the external blank to deform and finally form a frame-like product with the first shape.

[0062] The shape of the shaping surface 2011 of all the shaping modules 20 on the base 30 determines the shape of the final shaped frame 50, and the shape of the shaped frame 50 can be changed by changing the shape of the shaping surface 2011, thereby obtaining frame products of different shapes.

[0063] In some embodiments, as shown in Figure 6 and Figure 10 The driving member 10 includes a prism 102, and the upper part of the prism 102 is formed with a pyramid 103, and the side surface of the pyramid 103 is formed with a second driving slope 101.

[0064] Further, the prism 102 and the pyramid 103 have the same number of side edges, for example, the prism 102 is a quadrangular prism, and the pyramid 103 is a quadrangular pyramid, which is more convenient for arrangement and better control of the movement direction of the shaping module 20.

[0065] The prism 102 can be a quadrangular prism, a hexagonal prism, an octagonal prism, etc., and the corresponding pyramid 103 can be a quadrangular pyramid, a hexagonal pyramid, an octagonal pyramid, etc.

[0066] In this embodiment, the prism 102 of the driving member 10 is a quadrangular prism, and the pyramid 103 is a quadrangular pyramid, and there are four second driving slopes 101 and four shaping modules 20, and each shaping module 20 corresponds to a second driving slope 101.

[0067] In some embodiments, the sliding surface 2021 further includes a first sliding plane 20212, and the lower part of the first sliding plane 20212 can be obtained by beveling the first driving slope 20211, and the first sliding plane 20212 is used to abut the side surface of the prism 102. When the driving member 10 is switched from the first position to the second position, the shaping module 20 moves outward, and the first driving slope 20211 of the shaping module 20 is separated from the corresponding second driving slope 101, and at this time, the first sliding plane 20212 moves to abut the corresponding side surface of the prism 102.

[0068] It can be understood that when the prism 102 is a quadrangular prism, the prism 102 has four side surfaces, and each side surface corresponds to a first sliding plane 20212 of a shaping module 20, and each first sliding plane 20212 is in contact with the corresponding side surface of the prism 102 when sliding to a certain position.

[0069] By providing the first sliding plane 20212, the movement stability of the shaping module 20 is better ensured.

[0070] The aforementioned connecting surface 2012 can be a plane, and the connecting surface 2012 is parallel to the first sliding plane 20212 to better improve the connection stability.

[0071] In some implementations, such as Figure 9 As shown, the thickness H1 of the shaping part 201 along the first direction is not less than the thickness H2 of the push-pull part 202 along the first direction, that is, H1≥H2. This method makes the shaping part 201 thicker, which is more conducive to improving the stability of the molding process and also conducive to meeting the depth requirements of different molded parts. On the other hand, the thickness of the push-pull part 202 is relatively small, which can reduce the overall weight of the shaping module 20, reduce its driving force, and make its movement more flexible.

[0072] In some implementations, such as Figure 10 As shown, the tilt angle α of the second driving inclined surface 101 relative to the first direction Z is 2° to 88°. The above tilt angle determines the outward movement stroke of the shaping module 20, which can be selected according to actual needs.

[0073] In some embodiments, the tilt angle of the second driving ramp 101 relative to the first direction can be 30° to 60°.

[0074] Preferably, the second driving inclined surface 101 has an inclination angle of 45° relative to the first direction.

[0075] In some preferred embodiments, the axis of the drive member 10 coincides with the axis of the main sliding cavity 301 to ensure the smoothness of the movement of the drive member 10.

[0076] In some implementations, such as Figure 7 As shown, the base 30 is also provided with a plurality of circumferentially arranged auxiliary parts 303, and a receiving space 304 is formed between two adjacent auxiliary parts 303. Each receiving space 304 contains a shaping part 201. Each auxiliary part 303 has an auxiliary surface 3031, which is used to abut against the inner wall of the finally formed frame 50. The auxiliary surface 3031 plays an auxiliary shaping role during the forming process, which is more conducive to ensuring the accuracy of the shape of the final frame 50. For example, there are four shaping modules 20, and each shaping module 20 has an L-shaped shaping surface 2011. During the final forming, the auxiliary surface 3031 of each auxiliary part 303 is on the same plane as part of the side surfaces of the shaping surfaces 2011 on both sides, thereby better ensuring the flatness of the sides of the final frame.

[0077] Understandably, in some other methods, auxiliary part 303 may not be required.

[0078] In some embodiments, the slot 302 may be an open slot or a closed channel without a bottom opening.

[0079] It can be understood that when the above-mentioned slot 302 is an open slot with a bottom opening, the mold should be placed on a workbench during use, so that the bottom surface of the base 30 is supported by the workbench to prevent the shaping module 20 from falling off the base 30.

[0080] In this embodiment, the first shape is a rectangle, and the product of the rectangular frame 50 can be obtained by the above-mentioned mold.

[0081] In this embodiment, as shown in Figure 1 , the mold has one driving member 10, four shaping modules 20 and one base 30. The prism 102 in the driving member 10 is a quadrangular prism, and the pyramid 103 is a quadrangular pyramid. At this time, the shaping surface 2011 of each shaping module 20 is L-shaped, and the shaping surfaces 2011 of the four shaping modules 20 are enclosed to form a rectangle. The molding process of the rectangular frame 50 will be described in detail with this mold as an example:

[0082] The molding process of the above-mentioned rectangular frame 50 (see Figures 14-16 ) includes the following steps:

[0083] 1) As shown in Figure 1 and Figure 14 , the tubular blank 40 is sleeved on the outside of the molding mold, so that all four shaping modules 20 are located inside the tubular blank 40, and the driving member 10 is located at the first position. At the first position, the first driving inclined surface 20211 of each shaping module 20 is in contact with the corresponding second driving inclined surface 101 of the driving member 10;

[0084] Among them, the tubular blank 40 is a circular pipe-shaped blank;

[0085] 2) Push the driving member 10 to move upward in the first direction in the main body sliding cavity 301 of the base 30, so that the first driving inclined surface 20211 slides along the corresponding second driving inclined surface 101 to push each shaping module 20 to move outward, so that the shaping surface 2011 of each shaping module 20 abuts against the tubular blank 40 and gradually pushes and pulls the tubular blank 40 to deform. In this process, the tubular blank 40 gradually fits on the shaping surface 2011 of each shaping module 20, as shown in Figures 11-13 and Figures 14-15 , the shape of the blank gradually approaches the first shape-rectangle, until the final complete deformation of the rectangular frame 50, thereby realizing the conversion from the circular pipe-shaped blank to the rectangular frame 50.

[0086] Further, referring to Figures 11-13 , when the rectangular frame 50 is obtained, the shaping surface 2011 of each shaping module 20 is fitted with the inner wall of the rectangular frame 50.

[0087] If the base 30 is also provided with the auxiliary part 303, then in the process of forming the frame body 50 product, a part of the tubular blank 40 is also gradually attached to the auxiliary surface 3031 of each auxiliary part 303 (see Figures 11-13 ), so as to obtain a rectangular frame body product with higher precision.

[0088] It can be understood that if the size of the rectangular frame body to be formed is smaller, each shaping module 20 moves outward by a smaller distance, and at this time the first driving slope 20211 only needs to slide along the corresponding second driving slope 101 to a smaller displacement without sliding out of the second driving slope 101; if the size of the rectangular frame body to be formed is larger, each shaping module 20 needs to move outward by a larger distance, and at this time the first driving slope 20211 needs to slide along the corresponding second driving slope 101 and finally slide out of the second driving slope 101, so that the first sliding plane 20212 of the sliding surface 2021 moves to contact the corresponding side surface of the driving piece 10, at this time the driving piece 10 moves to the second position, and the distance of the outward movement of each shaping module 20 is the maximum distance.

[0089] Using the mold of the present embodiment to prepare the frame body product greatly simplifies the preparation process of the frame body product, and compared with the traditional drawing forming process, it does not need to be repeatedly drawn and annealed, and can be formed at one time, so that a frame body product with a thinner wall thickness can be directly prepared, and the thinnest wall thickness can reach 0.04mm, which is 1 / 5 of the wall thickness that can be achieved by the conventional drawing process;

[0090] In addition, using the mold of the present embodiment to prepare the frame body product can obtain a frame body product with no R angle or a smaller R angle (the R angle refers to the round angle formed by the edge of the product or the intersection of two planes, such as Figure 16 the R angle 501 in the figure), while the R angle of the formed product obtained by the traditional drawing forming process is larger, and the smallest R angle is 10-15 times the thickness of the material;

[0091] Using the mold of the present embodiment to prepare the frame body product has a simple process, not only improves the production efficiency, but also is more conducive to improving the size precision and quality of the product, and greatly reduces the production cost, has high universality, can be used alone or in cooperation with other equipment, and can prepare a variety of complex-shaped frame body products.

[0092] Embodiment Two

[0093] Referring to Figures 17-19 , the main difference between the present embodiment and embodiment one is that only two shaping modules 20 are placed in the present embodiment, the prismatic body 102 in the driving piece 10 adopts a quadrangular prism, the pyramid body 103 adopts a quadrangular pyramid, there are four second driving slopes 101, and only the shaping modules 20 are correspondingly arranged at the two oppositely arranged second driving slopes 101.

[0094] The shaping surfaces 2011 of the two shaping modules 20 mentioned above are both semi-circular. The shaping surfaces 2011 of these two oppositely arranged shaping modules 20 enclose an oblong shape. An oblong frame product can be produced by this mold. The molding process is as follows (see...). Figure 17 ):

[0095] 1) The tubular blank 40 is fitted onto the outside of the forming mold, so that all two shaping modules 20 are located inside the tubular blank 40, and the driving member 10 is located in the first position. In the first position, the first driving inclined surface 20211 of each shaping module 20 is in contact with the corresponding second driving inclined surface 101 on the driving member 10.

[0096] Among them, tubular billet 40 is a round tubular billet;

[0097] 2) The driving component 10 moves upward in the main body sliding cavity 301 of the base 30 along the first direction, so that the first driving inclined surface 20211 slides along the corresponding second driving inclined surface 101 and pushes each shaping module 20 outward, so that the shaping surface 2011 of each shaping module 20 abuts against the tubular blank 40 and gradually pushes and pulls the tubular blank 40 outward to deform it. In this process, the tubular blank 40 gradually fits onto the shaping surface 2011 of each shaping module 20, and its shape gradually approaches the first shape - oblong, until it is finally completely deformed into an oblong frame 50, thereby realizing the transformation from a round tubular blank to an oblong frame 50.

[0098] When forming the oblong frame 50, refer to the mold status. Figure 18 .

[0099] Similarly, see Figures 20-21 If the shaping surfaces 2011 of the two shaping modules 20 are both rectangular, and the shaping surfaces 2011 of the two oppositely arranged shaping modules 20 enclose a rectangle, a rectangular frame-like product can be produced by this mold, which will not be elaborated here.

[0100] Example 3

[0101] See Figures 22-23 The main difference between this embodiment and embodiment one is that this embodiment still has four shaping modules 20, but the shape of the shaping surface 2011 of each shaping module 20 is different from that in embodiment one.

[0102] Among them, the shaping surfaces 2011 of the four shaping modules 20 are enclosed in a parallelogram. With this mold, a frame-like product with a parallelogram shape can be prepared. The specific process steps are roughly the same as in Example 1, and will not be repeated here.

[0103] Example 4

[0104] Referring to Figures 24-25 The main difference between the embodiment and the embodiment one is that the embodiment still has four shaping modules 20, but the shape of the shaping surface 2011 of each shaping module 20 is different from that of the embodiment one.

[0105] The shaping surfaces 2011 of the four shaping modules 20 are enclosed in a trapezoidal shape, so that the mold can be used to prepare a trapezoidal frame product, and the specific process steps are substantially the same as those of the embodiment one, which will not be described here.

[0106] All the optional technical solutions described above can be combined to form optional embodiments of the present application, that is, any number of embodiments can be combined to meet the needs of different application scenarios, which are all within the protection scope of the present application and will not be described one by one here.

[0107] It should be noted that the above embodiments are only examples for clear illustration, and are not a limitation on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
