[0036] In the production process of automobile seat brackets, rolling followed by cold rolling is usually used. During the cold rolling process, the contour of the seat bracket is difficult to stably control within a small range, and there will be some products that exceed the customer's demand range. The traditional way is to develop two or more sets of molds to shape the contour of the seat bracket. Each set of molds is equipped with a corresponding mold bracket, which is costly.

[0037] In order to solve the problems in the prior art, the present embodiment provides a bidirectional shaping device, which includes a mold support, a first shaping mold 200, and a second shaping mold 300. The mold support includes a base 110 and a pressing plate 120. The pressing plate 120 is provided with a die mounting portion on the side facing the base 110, and the side of the pressing plate 120 facing away from the base 110 is connected to the driving member. The first shaping mold 200 includes a first die and a first support assembly 220. The first die is installed on the die mounting portion, and the first support assembly 220 is arranged on the base 110. The first die cooperates with the first support assembly 220 to shape the upturned product 10, so that the contour of the product 10 meets the required range; the second shaping mold 300 includes a second die and a second support assembly 320. The second die is installed on the die mounting portion, and the second support assembly 320 is arranged on the base 110. The second die cooperates with the second support assembly 320 to shape the downward bent product 10, so that the contour of the product 10 meets the required range.

[0038] The bidirectional shaping device provided in this embodiment reduces the development cost of the mold support, improves the compatibility of the mold support, and saves production costs by installing a first shaping mold 200 on the mold support to shape the upturned product 10, or installing a second shaping mold 300 on the mold support to shape the downward bent product 10.

[0039] Specifically, the product 10 in this embodiment is a seat support, which includes a first U-shaped groove 11, and second U-shaped grooves 12 are respectively provided on both sides of the first U-shaped groove 11, and the opening direction of the first U-shaped groove 11 is opposite to the opening direction of the two second U-shaped grooves 12. One end of the first support component 220 is connected to the base 110. When the seat support is placed on the first support component 220, the opening of the first U-shaped groove 11 is downward, and the end of the first support component 220 away from the base 110 extends into the first U-shaped groove 11 and supports the seat support. The first die includes two first pressing blocks 210, which are relatively arranged on both sides of the die mounting portion, and the two first pressing blocks 210 are respectively abutted against the two bottom walls of the two second U-shaped grooves 12 that are away from each other. When the driving member drives the two first pressing blocks 210 to drop, the two sides of the seat support that are upturned can be pressed downward until the contour of the seat support is within the standard range.

[0040] Optionally, the first support assembly 220 includes a product positioning block 221 and a limiting block 222. The product positioning block 221 is slidably disposed on the base 110, and the limiting block 222 is disposed at the bottom of the product positioning block 221. The limiting block 222 is used to limit the downward movement of the product positioning block 221, so that the product positioning block 221 forms a strong support for the middle part of the product 10, thereby improving the shaping effect. Specifically, the shape of the top of the product positioning block 221 matches the shape of the first U-shaped groove 11, thereby improving the supporting effect.

[0041] Optionally, when it is necessary to reshape the seat support with two sides bent downward, the first shaping mold 200 is removed from the mold support, and the second shaping mold 300 is installed on the mold support. Specifically, the second support assembly 320 includes two reverse pressing blocks 321, which are relatively arranged on the base 110, and the two reverse pressing blocks 321 are respectively abutted against the opposite sides of the two openings of the two second U-shaped grooves 12; the second die includes two second pressing blocks 310, which are respectively arranged on both sides of the die mounting portion, and the two second pressing blocks 310 are respectively abutted against the parts of the two bottom walls of the two second U-shaped grooves 12 that are close to each other. When the driving member drives the two second pressing blocks 310 to descend, the middle part of the seat support is subjected to downward pressure, and due to the action of the two reverse pressing blocks 321, the two sides of the seat support are tilted upward, thereby reshaping the bent seat support.

[0042] It should be noted that before shaping, the products 10 in the same state need to be classified, for example, the upturned seat bracket and the downward bent seat bracket need to be classified separately, and then the first shaping mold 200 is installed on the mold bracket to shape the upturned seat bracket. After the upturned seat bracket is completely shaped, the first shaping mold 200 is removed from the mold bracket, and the second shaping mold 300 is installed on the mold bracket to shape the downward bent seat bracket.

[0043] Optionally, a protrusion is provided on the mold mounting portion 121, and mounting positions are provided on both sides of the protrusion respectively. The two mounting positions are used to install two first pressing blocks 210 or two second pressing blocks 310. The first pressing blocks 210 or the second pressing blocks 310 are fastened to the protrusion by screws. This fastening method is simple and reliable, and can ensure that the mold will not loosen or shift during the shaping process, thereby ensuring the consistency and stability of the shaping effect.

[0044] Optionally, the second support assembly 320 further includes an elastic member 322, which is used to replace the limit block 222 to allow the product positioning block 221 to float up and down. It can be understood that when the limit block 222 is replaced by the elastic member 322, the combination of the product positioning block 221 and the elastic member 322 can be used to assist in supporting the seat support during the shaping process of the bent seat support, thereby improving the stability of the seat support.

[0045] Optionally, the elastic member 322 in this embodiment is a spring with good elasticity, which ensures that the product positioning block 221 is fully fitted with the seat bracket, prevents the seat bracket from shaking unnecessary during the shaping process, and improves the stability of the support.

[0046] Optionally, a guide groove is provided on the side of the product positioning block 221, and a guide block is provided on the base 110. The guide block is slidably connected to the guide groove, which can guide the movement process of the product positioning block 221, thereby improving the stability of the product positioning block 221 supporting the seat bracket.

[0047] Optionally, the base 110 includes an upper base plate 111, a lower base plate 113 and a vertical plate 112, the vertical plate 112 is arranged between the upper base plate 111 and the lower base plate 113, the upper end of the vertical plate 112 is connected to the upper base plate 111, and the lower end of the vertical plate 112 is connected to the lower base plate 113, and an assembly hole is provided in the middle of the upper base plate 111, and the product positioning block 221 is slidably penetrated in the assembly hole, so that the structure of the base 110 is more compact and beautiful. When the first shaping mold 200 is installed, the upper limit block 222 is padded at the bottom of the product positioning block 221, so that the product positioning block 221 forms a fixed support for the seat bracket; when the second shaping mold 300 is installed, the elastic member 322 is padded at the bottom of the product positioning block 221, so that the product positioning block 221 forms an elastic support for the seat bracket.

[0048] Optionally, the mold support also includes a plurality of guide rods 122, the die mounting portion is arranged on the pressing plate 120, the pressing plate 120 is connected to the output end of the driving member, and the plurality of guide rods 122 are evenly distributed between the pressing plate 120 and the base 110, one end of the guide rod 122 is fixed to the pressing plate 120, and the other end is slidably connected to the base 110, thereby guiding the rising and falling process of the first die or the second die on the die mounting portion, thereby improving the stability of the shaping process.

[0049] Optionally, the mold support further includes a limit assembly 400, which is used to limit the descending distance of the pressing plate 120 to prevent excessive shaping and improve the accuracy of shaping.

[0050] Optionally, the limiting assembly 400 includes a first limiting rod 410 and a second limiting rod 420, wherein the first limiting rod 410 is disposed on the pressing plate 120, and the second limiting rod 420 is disposed on the base 110 opposite to the first limiting rod 410, and the first limiting rod 410 can abut against the second limiting rod 420. The limiting assembly 400 has a simple structure, and through the cooperation of the first limiting rod 410 and the second limiting rod 420, the descending distance of the pressing plate 120 is precisely controlled, which can not only effectively prevent excessive shaping, but also ensure the processing quality and consistency of the product 10.

[0051] Optionally, the mold bracket also includes a supporting tooling 500, which includes a connecting plate 510 and a supporting block 520.
