DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: This example is intended to help solve the problem. Please refer to Figure 1-Figure 9A forging device and method for a hinge beam, comprising a forging table 1, a plurality of second guide rods 4 are fixed to the outer wall of the forging table 1, a lower lifting plate 3 is slidably provided on the outer wall of the second guide rod 4, a motor 11 is mounted on the lower lifting plate 3, an output shaft 12 is fixed to the output end of the motor 11, a fixed frame 10 is fixed to one end of the output shaft 12, a through slot 20 is provided on the fixed frame 10, a fourth guide rod 24 is fixed to the inner wall of the fixed frame 10, and two lower dies 26 are slidably provided on the outer wall of the fourth guide rod 24; The inner wall of the fixed frame 10 is slidably provided with a resisting block 18 for pushing the lower mold 26 to separate. A toggle rod 43 is fixed on the lower mold 26. The outer wall of the resisting block 18 is provided with a resisting edge 21 for resisting the toggle rod 43. A fixed plate 14 is fixed on the lower lifting plate 3, a first guide rod 22 is fixed on the outer wall of the abutment block 18, an annular groove 16 for guiding the moving track of the first guide rod 22 is provided on the fixed plate 14, and a smooth groove 161 is provided in the annular groove 16; A support plate 6 is fixed to the end of the second guide rod 4, a punch 7 is installed on the outer wall of the support plate 6, an upper lifting plate 8 is fixed to the output end of the punch 7, the upper lifting plate 8 is slidably sleeved on the outer wall of the second guide rod 4, and an upper mold 9 is assembled on the upper lifting plate 8.

[0021] This embodiment also discloses a forging method of a hinge beam forging device, which further includes the following steps: S1. First, a steel billet to be forged is placed in the cavity between the two combined lower dies 26, and then the punch 7 is started to force the upper die 9 to press down to forge the steel billet in the lower die 26; S2. After the forging is completed, the punch 7 is started to move the upper die 9 upward and reset, and then the motor 11 is started to rotate the fixed frame 10. During the rotation of the fixed frame 10, the two closely attached lower dies 26 are gradually separated. The separation of the lower dies 26 can promote the separation of the steel billet from the lower die 26, and as the fixed frame 10 continues to rotate, the steel billet after forging is dumped out; S3, after the two lower dies 26 are separated to the maximum extent, as the fixed frame 10 continues to rotate, the sleeve rod 39 is prompted to knock the outer wall of the lower die 26, so that the metal debris adhered to the lower die 26 due to forging is separated; S4. As the lower mold 26 continues to rotate, the sleeve rod 39 can change its angle to knock on other positions of the outer wall of the lower mold 26. Knocking on different positions can make a larger range of adhered iron chips in the lower mold 26 fall off.

[0022] When using the forging device, firstly, the steel blank to be forged is placed in the space formed between the two lower dies 26, and then the punch 7 is started. After the punch 7 is started, the upper lifting plate 8 with the output end begins to slide downward along the second guide rod 4, and the upper lifting plate 8 slides downward while the upper die 9 slides downward, until the upper die 9 touches the steel blank downward, and presses the steel blank, the lower die 26 and the fixed frame 10 downward, so that the entire lower lifting plate 3 is forced downward and compresses the first return spring 5 to move downward until the compression limit of the first return spring 5 is reached, and then the steel blank begins to be compressed and deformed, and the formed steel blank is in the shape of a hinge beam; After the forging is completed, the motor 11 is started. After the motor 11 is started, the output shaft 12 at the output end rotates, and the output shaft 12 rotates with the fixed frame 10. When the fixed frame 10 starts to rotate, the first guide rod 22 rotates along with the rotation of the fixed frame 10. The rotation of the first guide rod 22 makes it slide along the smooth groove 161, and gradually slides into the annular groove 16 along the inclined surface of the smooth groove 161. At this time, as the first guide rod 22 gradually slides into the annular groove 16 with the first ball 23, the gradually rising inclined surface of the smooth groove 161 causes the first guide rod 22 to be forced to move in the direction away from the fixed disk 14. The movement of the first guide rod 22 brings the resistance block 18 to move synchronously, and the resistance block 18 will compress the second reset spring 19 during the movement to facilitate subsequent reset. The movement of the resistance block 18 causes the resistance edge 21 on its outer wall to come into resistance with the outer walls of the two toggle rods 43. The resistance causes the two toggle rods 43 to gradually move the lower mold 26 in opposite directions along the fourth guide rod 24 under force. When the first guide rod 22 and the first ball 23 slide onto the annular groove 16, the two lower molds 26 are at the maximum degree of separation. At this time, the rotation and tilting of the fixed frame 10 will also cause the formed steel billet between the two separated lower molds 26 to detach and fall, and the single forging is ended.

[0023] In this embodiment: by starting the motor 11 after forging is completed, the lower die 26 can be gradually separated after forging is completed, and as the motor 11 is started, the lower die 26 can be gradually tilted and separated at the same time, and the internal molded steel billet can be poured out for better demoulding.

[0024] Embodiment 2: This embodiment is intended to help solve the problem that during the forging process, a layer of metal debris will fall off the outer wall of the red-hot steel billet after forging impact. These debris are easily adhered to the inner wall of the lower die 26 due to pressure. If they are not cleaned, the inner wall of the lower die 26 will become thicker, resulting in unclear contours in the die. Please refer to Figure 1-Figure 9A forging device and method for a hinge beam, wherein a second slide groove 27 is provided on a lower die 26, a fifth guide rod 28 is fixed to the inner wall of the second slide groove 27, a first slide groove 25 is provided on a fourth guide rod 24, the fifth guide rod 28 is arranged in the first slide groove 25, a third return spring 29 is sleeved on the outer wall of the fifth guide rod 28, one end of the third return spring 29 is fixed to the inner wall of the second slide groove 27, and the third return spring 29 abuts against the notch of the first slide groove 25; A third guide rod 17 is fixed to the outer wall of the fixed frame 10, and a second return spring 19 is sleeved on the outer wall of the third guide rod 17. One end of the second return spring 19 is fixed to the outer wall of the fixed frame 10, and the other end of the second return spring 19 is fixed to the outer wall of the abutment block 18. The abutment block 18 is slidably sleeved on the outer wall of the third guide rod 17. A plurality of evenly distributed first protrusions 13 are fixed to the outer wall of the lower lifting plate 3, and the first protrusions 13 are set to be hemispherical; A sliding frame 31 is fixed on the fixed frame 10, a sixth guide rod 32 is fixed on the inner wall of the sliding frame 31, a fourth return spring 33 is sleeved on the sixth guide rod 32, one end of the fourth return spring 33 is fixed to the inner wall of the sliding frame 31, a first slider 34 is fixed to the other end of the fourth return spring 33, and the first slider 34 is slidably sleeved on the sixth guide rod 32; A second guide rod 35 is provided on the first slider 34, and a sleeve 37 is connected to the second guide rod 35. A torsion spring 36 is sleeved on the second guide rod 35, and one end of the torsion spring 36 is fixed with the sleeve 37, and the other end of the torsion spring 36 is fixed to the outer wall of the first slider 34; A fifth return spring 38 is fixed to the inner wall of the sleeve 37, a sleeve rod 39 is fixed to the other end of the fifth return spring 38, and a second ball 40 is rotatably provided at the end of the sleeve rod 39; A first ball 23 is rotatably provided at the end of the first guide rod 22; A third guide rod 41 is fixed to the outer wall of the second guide rod 35, and a third ball 42 is rotatably provided at the end of the third guide rod 41; The outer wall of the second guide rod 4 is sleeved with a first return spring 5, one end of the first return spring 5 is fixed to the outer wall of the forging table 1, and the other end of the first return spring 5 is fixed to the outer wall of the lower lifting plate 3. A plurality of first guide rods 2 are fixed to the outer wall of the forging table 1, and the lower lifting plate 3 is slidably sleeved on the outer wall of the first guide rod 2.

[0025] After the forging device is forged, as the fixed frame 10 continues to rotate, the third guide rod 41 follows the synchronous rotation, and the third guide rod 41 rotates and continuously hits the evenly distributed first protrusion 13. When the third ball 42 at the end of the third guide rod 41 hits the surface of the first protrusion 13, the third guide rod 41 and the third ball 42 start to climb along the hemispherical surface of the first protrusion 13 with the circumferential movement. At this time, the third guide rod 41 will move in the direction away from the fixed plate 14, prompting the third guide rod 41 to move quickly with the second guide rod 35 and the sleeve 37 towards the direction close to the lower mold 26. At this time, the first slider 34 follows the synchronous movement along the outside of the sixth guide rod 32 and compresses the fourth return spring 33 to facilitate subsequent reset, until the second ball 40 hits the outer wall of the lower mold 26, and the hit will knock on the surface of the lower mold 26, and during the knocking, the second ball 40 presses the fifth return spring 38 with the sleeve rod 39 to buffer and prevent it from getting stuck. Since a plurality of first protrusions 13 are evenly arranged, when the third guide rod 41 and the third ball 42 pass through a plurality of first protrusions 13, the surface of the lower mold 26 can be knocked quickly and repeatedly to cause the metal debris adhering to the inner wall of the lower mold 26 to fall off. Since the opening of the lower mold 26 is rotated downward at this time, the metal debris can fall to the outside. Since the two lower molds 26 are at the maximum separation from each other at this time, that is, the two lower molds 26 are at the corresponding positions of the two grooves 30 opened on the inner wall of the fixed frame 10, it should be noted that The inner contour of the groove 30 matches the outer contour of the lower mold 26. Therefore, each time the lower mold 26 is struck, it will move with the fifth guide rod 28 in the direction away from the resistance block 18. At this time, the lower mold 26 will compress the third return spring 29 together with the notch of the first slide groove 25. When a single strike is completed, the third return spring 29 will rebound instantly and quickly return the lower mold 26 to its original position. Subsequently, due to the nature of the spring, it will vibrate repeatedly for several times, so as to better shake off the debris adhered to the inner wall of the lower mold 26.

[0026] In this embodiment: by continuing to start the motor 11, when the lower mold 26 opens downward after separation, the third guide rod 41 and the third ball 42 continuously knock on the outer wall of the lower mold 26, so that the metal debris adhered to the lower mold 26 due to forging will be separated from the inner wall and fall to the outside, preventing the metal debris from adhering to the inner wall of the lower mold 26 and accumulating on the inner wall of the lower mold 26, causing the inner contour of the mold to be blurred, and when the lower mold 26 is knocked, it will vibrate repeatedly and shake off the debris on the inner wall.

[0027] Embodiment 3: This embodiment is intended to solve the problem that only a single position of the lower mold 26 is struck, and the debris at other positions of the lower mold 26 is not easy to fall off, and the scope of the strike is limited. Please refer to Figure 1-Figure 9, a forging device and forging method of a hinge beam, a plurality of evenly distributed second protrusions 15 are fixed to the outer wall of a fixed plate 14, and the second protrusions 15 are set as arc-shaped protrusions.

[0028] In order to increase the range of the knocking effect on the lower mold 26, when the fixed frame 10 continues to rotate with the third guide rod 41, the third guide rod 41 will conflict with the surface of the second protrusion 15 at a certain distance. The conflict will cause the third guide rod 41 to move along the contour of the second protrusion 15 on the arc surface, causing the third guide rod 41 to bring the second guide rod 35 to turn upward by a certain angle with the rotation point of the inner wall of the first slider 34 as the rotation point. The turning will put the torsion spring 36 in a torsionally tightened state for subsequent reset, and the turning at this time will cause the sleeve The cylinder 37 synchronously flips a certain angle with the second guide rod 35, that is, at this time, the position of the sleeve 37 and the sleeve rod 39 toward the lower mold 26 changes. At this time, when the third guide rod 41 and the third ball 42 hit the surface of the first protrusion 13, the position where the sleeve rod 39 and the second ball 40 knock on the outer wall of the lower mold 26 will change, that is, the knocking and vibration effect is performed on a larger range of the lower mold 26. It should be noted that in the setting, no matter how the third guide rod 41 is deflected, the third ball 42 can keep hitting the surface of the first protrusion 13.

[0029] In this embodiment: during the rotation of the lower mold 26, the third guide rod 41 and the third ball 42 change the knocking position of the lower mold 26, so that the lower mold 26 can be knocked over a larger range, that is, the knocking and vibration can be performed on a larger range of the inner wall of the lower mold 26, further increasing the degree of cleaning of the debris on the inner wall of the lower mold 26.

[0030] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

The forging device for a hinge beam according to claim 1, characterized in that: The outer wall of the second guide rod (4) is sleeved with a first return spring (5), one end of the first return spring (5) is fixed to the outer wall of the forging table (1), and the other end of the first return spring (5) is fixed to the outer wall of the lower lifting plate (3), and a plurality of first guide rods (2) are fixed to the outer wall of the forging table (1), and the lower lifting plate (3) is slidably sleeved on the outer wall of the first guide rod (2).

9. The forging device for a hinge beam according to claim 1, characterized in that: A support plate (6) is fixed to the end of the second guide rod (4), a punch (7) is mounted on the outer wall of the support plate (6), an upper lifting plate (8) is fixed to the output end of the punch (7), the upper lifting plate (8) is slidably sleeved on the outer wall of the second guide rod (4), and an upper mold (9) is mounted on the upper lifting plate (8).

10. A forging method for a hinge beam forging device according to any one of claims 1 to 9, characterized in that: The following steps are also included: S1. First, a steel billet to be forged is placed in the cavity between two combined lower dies (26), and then a punch (7) is started to cause the upper die (9) to press downward to forge the steel billet in the lower die (26); S2, after the forging is completed, the punch (7) is started to move the upper die (9) upward and reset, and then the motor (11) is started to rotate the fixed frame (10). During the rotation of the fixed frame (10), the two closely attached lower dies (26) are gradually separated. The separation of the lower dies (26) can promote the separation of the steel billet from the lower die (26), and as the fixed frame (10) continues to rotate, the steel billet after forging is dumped out; S3, after the two lower dies (26) are separated to the maximum extent, as the fixed frame (10) continues to rotate, the sleeve rod (39) strikes the outer wall of the lower die (26), so that the metal debris adhered to the lower die (26) due to forging is separated; S4. As the lower mold (26) continues to rotate, the sleeve rod (39) can change its angle to strike other positions of the outer wall of the lower mold (26). Striking different positions can cause a wider range of adhered iron chips in the lower mold (26) to fall off.
