The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0039] For workpieces with flatness requirements, due to the influence of thermal stress or mechanical stress on the workpieces, therefore, after the workpieces are welded by heating, deformation phenomena such as bending or warping are likely to occur. In order to facilitate the shaping of the bent or warped workpieces to correct the flatness, shaping jigs are usually used to shape the workpieces.

[0040] Currently, the shaping jig generally includes a base and a pressing plate. The base is provided with a groove adapted to a workpiece of a certain shape, and the pressing plate is connected to the base in a liftable manner. After the workpiece is clamped into the groove, the pressing plate is lifted to clamp and shape the workpiece to correct the flatness of the workpiece. However, the above structure can only be adapted to workpieces of a certain shape, resulting in low adaptability of the shaping jig.

[0041] In view of this, the present utility model provides an embodiment of a shaping fixture 100, which can press and shape workpieces to be shaped with different shapes, improving the adaptability of the shaping fixture 100.

[0042] For the above-mentioned shaping fixture 100, please refer to Figures 1 to 4 , the shaping fixture 100 includes a base 1, a first lifting component 2, a shaping component 3 and a positioning component 4. The first lifting component 2 is arranged on the base 1. The shaping component 3 includes a shaping base 31, a pressing member 32, a first shaping member 33 and a second shaping member 34. The shaping base 31 is arranged on the base 1. The shaping base 31 is provided with a bearing portion 311 for bearing the workpiece to be shaped. The pressing member 32, the first shaping member 33 and the second shaping member 34 are all connected to the first lifting component 2. The first lifting component 2 is used to drive the pressing member 32, the first shaping member 33 and the second shaping member 34 to make linear reciprocating motions synchronously along a preset axis. The pressing member 32, the first shaping member 33 and the second shaping member 34 are all located above the shaping base 31. The pressing member 32 is aligned with the bearing portion 311. The first shaping member 33 and the second shaping member 34 are located on opposite sides of the pressing member 32. Along the preset axis, at least part of the first shaping member 33 and the second shaping member 34 protrudes from the end of the pressing member 32 facing the shaping base 31. The ends of the first shaping member 33 and the second shaping member 34 facing the shaping base 31 are flush. The positioning component 4 is arranged on the shaping base 31 and is used to position the workpiece to be shaped. Among them, the preset axis refers to the direction of the pressing member 32 facing the shaping base 31.

[0043] In the above manner, the positioning component 4 positions the workpiece to be shaped, the pressing member 32 and the bearing portion 311 cooperate to press and fix the workpiece to be shaped, and the first shaping member 33 and the second shaping member 34 shape the workpiece to be shaped, so that the embodiment of the present utility model can press and shape workpieces to be shaped with different shapes, improving the adaptability of the shaping fixture 100. In addition, in the above manner, the first shaping member 33 and the second shaping member 34 shape the workpiece to be shaped synchronously from multiple positions, so that the embodiment of the present utility model can better correct the flatness and reduce the bending and warping phenomena.

[0044] For the above-mentioned shaping component 3, please refer to Figure 3 , the first shaping member 33 is provided with a first inclined portion 331. Along the preset axis, at least part of the first inclined portion 331 protrudes from the end of the pressing member 32 facing the shaping base 31. The side of the first inclined portion 331 away from the pressing member 32 is close to the shaping base 31, and the side of the first inclined portion 331 close to the pressing member 32 is away from the shaping base 31, and / or, the second shaping member 34 is provided with a second inclined portion 341. Along the preset axis, at least part of the second inclined portion 341 protrudes from the end of the pressing member 32 facing the shaping base 31. The side of the second inclined portion 341 away from the pressing member 32 is close to the shaping base 31, and the side of the second inclined portion 341 close to the pressing member 32 is away from the shaping base 31.

[0045] In the above manner, due to the presence of the first inclined portion 331 and the second inclined portion 341, during the shaping process, the protruding portions of the first inclined portion 331 and the second inclined portion 341 first contact the workpiece to be shaped, and then gradually apply uniform pressure to the shaping seat 31, thereby guiding the workpiece to be shaped step by step. In this process, the shaping can be smoother and the sudden stress concentration problem is reduced. At the same time, due to the presence of the first inclined portion 331 and the second inclined portion 341, during the shaping process, the first shaping member 33 and the second shaping member 34 can select the maximum thickness position of the workpiece to be shaped as the pressure point to avoid selecting the minimum thickness position of the workpiece to be shaped as the pressure point to produce local indentation or deformation. In addition, in the above manner, the first inclined portion 331 and the second inclined portion 341 can reduce the material cost of the first shaping member 33 and the second shaping member 34.

[0046] In some embodiments, see Figure 3 , a third inclined portion 3111 is provided on one side of the bearing portion 311, a fourth inclined portion 3112 is provided on the other side of the bearing portion 311, the third inclined portion 3111 is aligned with the first inclined portion 331, and the inclination direction and inclination of the third inclined portion 3111 are equal to the inclination direction and inclination of the first inclined portion 331, and the fourth inclined portion 3112 is aligned with the second inclined portion 341, and the inclination direction and inclination of the fourth inclined portion 3112 are equal to the inclination direction and inclination of the second inclined portion 341. In the above manner, the presence of the third inclined portion 3111 and the fourth inclined portion 3112 enables the bearing portion 311 to adapt to different thickness positions of the bearing member to be shaped.

[0047] For the above shaping component 3, see Figure 3 The shaping seat 31 is provided with a first avoidance groove 312 and a second avoidance groove 313 on both sides of the bearing portion 311. The first avoidance groove 312 is aligned with the first shaping piece 33, and the second avoidance groove 313 is aligned with the second shaping piece 34. In the above manner, the first avoidance groove 312 provides a movement space for the first shaping piece 33, and the second avoidance groove 313 provides a movement space for the second shaping piece 34, so as to avoid the first shaping piece 33 and the second shaping piece 34 from colliding or interfering with the shaping seat 31. In addition, in the above manner, the first avoidance groove 312 and the second avoidance groove 313 can accommodate the irregular convex part of the piece to be shaped, so that the shaping jig 100 can press and fix the irregular shaped piece to be shaped, thereby improving the adaptability of the shaping jig 100.

[0048] For positioning component 4 above, see Figure 4 and Figure 5, the positioning component 4 includes at least two positioning pins 41. The at least two positioning pins 41 are arranged on the shaping base 31. The at least two positioning pins 41 are located on one side of the bearing portion 311.

The second lifting component 5 is connected to the positioning component 4. The second lifting component 5 is used to drive the positioning component 4 to perform a linear reciprocating motion along a preset axis. In this way, the positioning component 4 can have a sinking function, so that the positioning component 4 can be separated from the workpiece to be shaped, which is convenient for disassembling the workpiece to be shaped after shaping.

[0050] For the above-mentioned second lifting component 5, please refer to Figure 6 and Figure 7 , the second lifting component 5 includes a support seat 51, a push rod 52, a first connecting piece 53, a connecting rod 54 and an elastic piece 55. The shaping base 31 is provided with a sliding space 314. The support seat 51 is connected between the base 1 and the shaping base 31. The support seat 51 is provided with a lifting space 511.

The elastic piece 55 is connected between the other side of the first connecting piece 53 and the bottom wall of the lifting space 511. In this way, the positioning pin 41 can perform a linear reciprocating motion along a preset axis, so that the positioning pin 41 has a sinking function and a reset function. Among them, the sinking function is convenient for disassembling the workpiece to be shaped after shaping, and the reset function is convenient for reinstalling the workpiece to be shaped after disassembly.

[0051] For the movement process of the above-mentioned second lifting component 5, the example is as follows: First, push the push rod 52 to slide along the sliding space 314. Then, the connecting rod 54 slides along the inclined groove 521. Immediately afterwards, the connecting rod 54 descends along the preset axis. Then, the first connecting piece 53 follows the connecting rod 54 to descend along the preset axis to realize the sinking of the positioning pin 41. At this time, the elastic piece 55 is compressed and deformed. Finally, push the push rod 52 in the reverse direction to slide along the sliding space 314, so that the elastic piece 55 restores deformation, and the connecting rod 54 and the first connecting piece 53 rise synchronously along the preset axis to realize the reset of the positioning pin 41.

In this way, by rotating the screw, the nut is disengaged from or abutted against the base 1, so that the clamping block is clamped or loosened, enabling the support base 51 to be locked or unlocked, and further enabling the second lifting assembly 5 to be locked or unlocked.

[0053] Please refer to Figure 8 , the shaping fixture 100 includes guide posts 6. The guide posts 6 are connected to the first lifting assembly 2. The shaping base 31 is provided with guide holes 315. The guide posts 6 are located above the guide holes 315 and are aligned with the guide holes 315. In this way, the cooperation between the guide posts 6 and the guide holes 315 provides a guiding function, which can guide the movement of the first lifting assembly 2, prevent the first lifting assembly 2 from shifting or shaking, improve the shaping accuracy of the first shaping member 33 and the second shaping member 34, and contribute to improving the shaping efficiency.
