Description

Technical Field

[0001] This application relates to the technical field of forging dies, and in particular to a forging equipment for manufacturing automotive steering arms. Background Technology

[0002] The steering arm is a crucial safety component in the automotive steering system. Each car uses two symmetrically shaped steering arms, which connect the wheels to the car body. During vehicle operation, the steering arms are subjected to frequent and complex variable stresses. Damage to these arms can lead to serious traffic accidents. Therefore, high requirements are placed on their manufacturing process and performance. Currently, automotive steering arms are mainly forged multiple times using forging dies. The forging process involves first installing an injection mold inside the die body. After the steering arm is formed for the first time inside the injection mold, it is removed and placed into a different cavity of the same die for further forging. After this forging, it is placed back into the forging die, where the scrap material at the edges is trimmed using the forging process. Finally, the steering arm is finished.

[0003] For example, Chinese patent document CN218835967U discloses a forging die for an automotive steering arm, including a forging die body and an injection frame. The injection frame is slidably connected to the top of the forging die body. Limiting components are fixedly connected to both sides of the forging die body, and support seats are fixedly connected to the four corners of the bottom of the forging die body. An auxiliary groove is provided at the bottom of the forging die body, and transmission boxes are provided on both sides of the bottom of the forging die body. A material-taking mechanism is fixedly connected to the bottom of the inner wall of the transmission box. The limiting components include limiting blocks, which are fixedly connected to the four corners of the bottom of the injection frame. A limiting groove is provided inside the forging die body to cooperate with the limiting blocks. The limiting blocks and limiting grooves are engaged. The material-taking mechanism includes a threaded ring, which is fixedly connected to the bottom of the inner wall of the transmission box. A screw is threadedly connected to the inside of the threaded ring, and a top plate is fixedly connected to the top of the screw. By setting a limiting component, the limiting component can limit and lock the injection molded frame, ensuring its use. When material needs to be picked up, the injection molded frame can be lifted by the material picking mechanism and then taken out.

[0004] In the aforementioned related technologies, when material needs to be removed, the injection mold can be lifted by the material removal mechanism, and then the injection mold can be removed to achieve the purpose of material removal. However, the removed car steering arm also needs to be placed into different cavities on the same mold for forging again. After forging, it needs to be placed back into the forging mold. The scrap at the edge of the formed car steering arm is cut off by the forging method. When the forged car steering arm is removed, there will be oxide scale in different cavities of the mold. The oxide scale needs to be removed before the new forging can be placed into the mold cavity, which will reduce the forging efficiency of the car steering arm. Summary of the Invention

[0005] This application provides a forging equipment for the production and processing of automotive steering arms, aiming to solve the problem of reduced forging efficiency of automotive steering arms in related technologies.

[0006] The forging equipment for manufacturing and processing automotive steering arms provided in this application adopts the following technical solution:

[0007] A forging device for manufacturing automotive steering arms includes a mounting frame, a drive assembly mounted on the mounting frame, an upper die fixed on the drive assembly, and a lower die mounted on the mounting frame. The drive assembly is used to drive the upper die to move away from or towards the lower die. The lower die includes a die body, a mounting shaft rotatably connected to the die body, and a rotating plate fixed on the mounting shaft. The die body has a first cavity mixed cutting chamber, and the rotating plate has a second cavity. A control assembly is provided on the die body to drive the rotating plate to rotate, so that the opening of the second cavity on the rotating plate faces downward and corresponds to the cutting chamber. A limiting assembly is provided on the rotating plate to limit the movement of the automotive steering arm in the second cavity.

[0008] By adopting the above technical solution, after the injection molding frame in the first cavity is forged, the drive assembly drives the upper mold to move upward, and then the control assembly drives the rotating plate to rotate. After the rotating plate rotates 180 degrees, the opening of the second cavity rotates downward. When the opening of the second cavity is completely downward, the opening of the second cavity corresponds to the cutting chamber. The car steering arm in the second cavity will fall into the cutting chamber under the action of gravity. At this time, the drive assembly drives the rotating plate to rotate in the opposite direction, so that the rotating plate is reset. After the reset, the opening of the second cavity on the rotating plate is set upward. Then, the drive assembly drives the upper mold to move downward. The moving upper mold cuts the scrap material on the edge of the car steering arm in the cutting chamber. During the rotation of the rotating plate, the oxide scale in the second cavity will also automatically fall off. In the subsequent forging process, there is no need to clean the oxide scale in the second cavity, thereby reducing the workload of the workers and improving the forging efficiency of the car steering arm.

[0009] Optionally, the upper surface of the mold body is provided with an installation groove for installing a limiting component. The limiting component includes a sliding rod fixedly connected in the installation groove and a limiting plate slidably connected to the sliding rod. A return spring is provided in the installation groove. One end of the return spring is fixed to the limiting plate, and the other end is fixed to the bottom wall of the installation groove. The limiting plate is provided with a locking component for locking the position of the moved limiting plate. The locking component causes the limiting plate to limit the car steering arm in the second cavity. When the locking component no longer limits the limiting plate, the return spring drives the limiting plate to reset, and the limiting plate no longer limits the car steering arm in the second cavity.

[0010] By adopting the above technical solution, during the rotation of the rotating plate, the locking assembly causes the limiting plate to limit the car steering arm in the second cavity. When the locking assembly no longer limits the limiting plate, the reset spring drives the limiting plate to reset, and the limiting plate no longer limits the car steering arm in the second cavity, so that the car steering arm in the second cavity can fall into the cutting cavity.

[0011] Optionally, the mold body is provided with a limiting groove, which is connected to the mounting groove. The snap-fit ​​assembly includes a connecting rod fixed to the limiting body, a snap-fit ​​rod sliding on the connecting rod, and a first snap-fit ​​block fixed to the snap-fit ​​rod. A snap-fit ​​spring is sleeved on the snap-fit ​​rod, with one end of the snap-fit ​​spring fixed to the connecting rod and the other end fixed to the first snap-fit ​​block. A second snap-fit ​​block is provided on the inner wall of the limiting groove. The second snap-fit ​​block reduces the communication position between the mounting groove and the limiting groove, and a snap-fit ​​inclined surface is provided on the second snap-fit ​​block. When the first snap-fit ​​block moves from the limiting groove into the mounting groove, the second snap-fit ​​block limits the position of the first snap-fit ​​block.

[0012] By adopting the above technical solution, when the limiting plate needs to limit the car steering arm in the second cavity, the locking rod and the first locking block on the limiting plate move from the limiting groove to the mounting groove, the locking spring is gradually compressed, and after the first locking block moves to the mounting groove, the locking spring drives the first locking block to reset, and the first locking block is limited by the second locking block. At this time, the limiting plate limits the car steering arm in the second cavity.

[0013] Optionally, the lower surface of the upper mold is provided with a first pushing component, which pushes the limiting plate to move so that the limiting plate limits the car steering arm in the second cavity. The mold body is provided with a second pushing component. After the rotating plate rotates 180 degrees, the second pushing component is used to push the limiting plate to no longer limit the car steering arm in the second cavity. The car steering arm in the second cavity falls into the cutting chamber under the action of gravity.

[0014] Optionally, the first pushing assembly includes a first pushing rod fixed to the lower surface of the upper mold and a first pushing inclined surface disposed on the first pushing rod. The first pushing inclined surface abuts against the end of the connecting rod, and the first pushing inclined surface on the first pushing rod is used to push the connecting rod, which is located in the limiting groove, to move.

[0015] By adopting the above technical solution, when the upper mold moves down to forge the car steering arm in the second cavity, the upper mold drives the first push rod to move down, and the first push inclined surface on the first push rod will push the connecting rod to move, thereby facilitating the connecting rod to drive the first snap block to move from the limiting groove to the mounting groove.

[0016] Optionally, the second pushing component includes a second pushing rod fixed to the upper surface of the mold body and a second pushing inclined surface disposed on the first snap-fit ​​block. During the rotation of the rotating plate, the second pushing rod will abut against the second pushing inclined surface on the first snap-fit ​​block.

[0017] By adopting the above technical solution, during the rotation of the rotating plate, the second push rod will abut against the second push inclined surface on the first locking block. As the rotating plate continues to rotate, the second push inclined surface will push the first locking block to move closer to the connecting rod, causing the first locking block to disengage from the second locking block. The connecting rod will move into the limiting groove, and the limiting plate will reset. The reset limiting plate will no longer limit the car steering arm in the second cavity, and the car steering arm will fall into the cutting cavity under the action of gravity.

[0018] Optionally, the limiting plate includes a limiting body, a plug plate slidably connected to the limiting body, and a plug slot formed on the plug plate. The plug slot is used to engage with the sliding rod. The limiting body is provided with an installation component, which is used to install the plug plate into the installation slot and make the plug on the plug plate engage with the sliding rod.

[0019] Optionally, the mounting assembly includes a mounting rod fixed to the limiting body and a mounting spring sleeved on the mounting rod, the plug plate being slidably connected to the mounting rod, and the mounting spring pushing the plug groove on the plug plate to abut against the surface of the sliding rod.

[0020] Optionally, the control component includes a control motor fixed on the mold body, a drive wheel fixed on the control motor, a driven wheel fixed on the mounting shaft, and a control belt wound around the drive wheel and the driven wheel. The output shaft of the control motor is fixedly connected to the drive wheel.

[0021] Optionally, the rotating plate is provided with multiple limiting components, each of which corresponds to a locking component.

[0022] By adopting the above technical solution, since multiple limiting components are set, the limiting effect of the car steering arm in the second cavity is better under the action of multiple limiting components, preventing the steering arm in the second cavity from falling off during the rotation of the rotating plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The drive component moves the upper mold downwards. The moving upper mold cuts the scrap material on the edge of the car steering arm in the cutting chamber. During the rotation of the rotating plate, the oxide scale in the second cavity will also fall off automatically. In the subsequent forging process, there is no need to clean the oxide scale in the second cavity, thereby reducing the workload of the workers and improving the forging efficiency of the car steering arm.

[0025] 2. When the snap-fit ​​assembly no longer limits the limiting plate, the reset spring drives the limiting plate to reset, and the limiting plate no longer limits the car steering arm in the second cavity, so that the car steering arm in the second cavity can fall into the cutting cavity.

[0036] The following combination Figures 1-9 This application will be described in further detail.

[0037] This application discloses a forging equipment for manufacturing automotive steering arms. (Refer to...) Figures 1 to 9 A forging equipment for manufacturing automotive steering arms includes a mounting frame 01, a drive assembly 02 mounted on the mounting frame 01, an upper die 03 fixed on the drive assembly 02, and a lower die 1 mounted on the mounting frame 01. The drive assembly 02 is used to drive the upper die 03 to move away from or towards the lower die 1. The lower die 1 has multiple chambers with different cross-sections. In this embodiment, the chambers include a first cavity 04, a second cavity 05, and a cutting cavity 06 mounted on the lower die 1. The drive assembly 02 is prior art, and its specific structure will not be described in detail.

[0038] In the forging process of the car steering arm, the injection mold is first placed into the first cavity 04. The upper mold 03 moves down to forge the injection mold in the first cavity 04. Then, the drive assembly 02 moves the upper mold 03 up and the robot arm takes out the forged car steering arm blank in the first cavity 04 and puts it into the second cavity 05. The drive assembly 02 moves the upper mold 03 down to forge the car steering arm blank in the second cavity 05. After forging, a ring of scrap will be formed on the surface of the car steering arm. Then, the forged part with a ring of scrap is put into the cutting chamber 06. The upper mold 03 moves down to cut the scrap edge of the car steering arm in the cutting chamber 06. The cut car steering arm falls out of the cutting chamber 06.

[0039] The lower mold 1 includes a mold body 11, a mounting shaft 12 rotatably connected to the mold body 11, and a rotating plate 13 fixed to the mounting shaft 12. A first cavity 04 is formed on the mold body 11, a second cavity 05 is formed on the rotating plate 13, and a cutting chamber 06 is formed on the mold body 11. A control component 2 is provided on the mold body 11 to drive the rotating plate 13 to rotate. After the rotating plate 13 rotates 180 degrees, the opening of the second cavity 05 on the rotating plate 13 faces downward and corresponds to the cutting chamber 06. Under the action of gravity, the second cavity 05... The car steering arm in cavity 05 falls into the cutting chamber 06. After the rotating plate 13 is reset, the upper mold 03 moves down. During the downward movement, the scrap material on the edge of the car steering arm in the cutting chamber 06 is disassembled. The cut car steering arm falls through the opening at the lower end of the cutting chamber 06. During the rotation of the rotating plate 13, the oxide scale in the second cavity 05 will also automatically fall off. In the subsequent forging process, there is no need to clean the oxide scale in the second cavity 05, thereby reducing the workload of the workers and improving the forging efficiency of the car steering arm.

[0040] The control assembly 2 includes a control motor 21 fixed on the mold body 11, a drive wheel 22 fixed on the control motor 21, a driven wheel 23 fixed on the mounting shaft 12, and a control belt 24 wound around the drive wheel 22 and the driven wheel 23. The output shaft of the control motor 21 is fixedly connected to the drive wheel 22. The control motor 21 drives the drive wheel 22 to rotate, which in turn drives the driven wheel 23 to rotate under the action of the control belt 24. The driven wheel 23 drives the mounting shaft 12 to rotate, and the mounting shaft 12 drives the rotating plate 13 to rotate, thereby facilitating the adjustment of the position of the rotating plate 13.

[0041] A limiting component 3 is provided on the rotating plate 13. The limiting component 3 is used to limit the car steering arm in the second cavity 05. During the rotation of the forged car steering arm driven by the rotating plate 13, it can prevent the car steering arm in the second cavity 05 from falling off. A first pushing component 4 is provided on the lower surface of the upper mold 03. The first pushing component 4 pushes the limiting component 3 to move, so that the limiting component 3 limits the car steering arm in the second cavity 05. A second pushing component 5 is provided on the mold body 11. After the rotating plate 13 rotates 180 degrees, the second pushing component 5 is used to push the limiting component 3 to no longer limit the car steering arm in the second cavity 05, so that the car steering arm in the second cavity 05 can fall into the cutting chamber 06 under the action of gravity.

[0042] An installation groove 6 is provided on the upper surface of the mold body 11. A limiting component 3 is set in the installation groove 6. The limiting component 3 includes a sliding rod 31 fixedly connected in the installation groove 6 and a limiting plate 32 slidably connected to the sliding rod 31. A return spring 33 is provided in the installation groove 6. One end of the return spring 33 is fixed to the limiting plate 32, and the other end is fixed to the bottom wall of the installation groove 6. A snap-fit ​​component 7 is provided on the limiting plate 32. The snap-fit ​​component 7 is used to snap the position of the moving limiting plate 32, so that the limiting plate 32 can better limit the car steering arm in the second cavity 05. When the snap-fit ​​component 7 no longer limits the limiting plate 32, the return spring 33 drives the limiting plate 32 to return to its original position, and the limiting plate 32 no longer limits the car steering arm in the second cavity 05.

[0043] The limiting plate 32 includes a limiting body 321, a plug-in plate 322 slidably connected to the limiting body 321, and a plug-in groove 333 formed on the plug-in plate 322. The plug-in groove 333 is used to engage with the sliding rod 31. An installation component 8 is provided on the limiting body 321. The installation component 8 is used to install the plug-in plate 322 into the installation groove 6, and to engage the plug-in plate 322 with the sliding rod 31. In this embodiment, sliding rods 31 are fixed on both side walls of the installation groove 6. Since there are two sliding rods 31, there are also two plug-in plates 322 on the limiting body 321, and there are also two installation components 8 on the limiting body 321. The installation component 8 can engage the plug-in grooves 333 on the two plug-in plates 322 with the two sliding rods 31.

[0044] The mounting assembly 8 includes a mounting rod 81 fixed to the limiting body 321 and a mounting spring 82 sleeved on the mounting rod 81. The plug plate 322 is slidably connected to the mounting rod 81. The mounting spring 82 pushes the plug groove 333 on the plug plate 322 to abut against the surface of the sliding rod 31. In this embodiment, the mounting rod 81 and the sliding rod 31 are set perpendicularly. During the installation of the limiting body 321, the operator uses a tool to push the two plug plates 322 closer to each other, and the mounting spring 82 is compressed. After the plug groove 333 on the plug plate 322 corresponds to the sliding rod 31, the operator releases the two plug plates 322. Under the action of the mounting spring 82, the two plug plates 322 are pushed away from each other, and finally the plug groove 333 on the two plug plates 322 are locked on the sliding rod 31. At this time, the plug plate 322 drives the limiting body 321 to slide on the sliding rod 31. During the sliding process, the steering arm of the car in the second cavity 05 can be limited.

[0045] A limiting groove 61 is provided on the mold body 11. The limiting groove 61 is connected to the mounting groove 6. When the snap-fit ​​component 7 is in the limiting groove 61, the limiting plate 32 cannot limit the car steering arm in the second cavity 05. When the snap-fit ​​component 7 enters the mounting groove 6 from the limiting groove 61, the limiting plate 32 limits the car steering arm in the second cavity 05. The snap-fit ​​component 7 includes a connecting rod 71 fixed on the limiting body 321, a snap-fit ​​rod 72 sliding on the connecting rod 71, and a first snap-fit ​​block 73 fixed on the snap-fit ​​rod 72. A snap-fit ​​spring 74 is sleeved on the snap-fit ​​rod 72. One end of the snap-fit ​​spring 74 is fixed on the connecting rod 71, and the other end is fixed on the first snap-fit ​​block 73. In this embodiment, two snap-fit ​​rods 72 are provided on the connecting rod 71. Each snap-fit ​​rod 72 is fixed with a first snap-fit ​​block 73, and each snap-fit ​​rod 72 is sleeved with a snap-fit ​​spring 74.

[0046] A second locking block 75 is provided on the inner wall of the limiting groove 61. In this embodiment, two second locking blocks 75 are provided. The two second locking blocks 75 reduce the communication position between the mounting groove 6 and the limiting groove 61. A locking inclined surface 76 is provided on the second locking block 75. The locking inclined surface 76 facilitates the movement of the first locking block 73 from the limiting groove 61 into the mounting groove 6. Then, it cannot enter the limiting groove 61 from the mounting groove 6. At this time, the position of the first locking block 73 is limited by the second locking block 75. The positioning plate moves to limit the car steering arm in the second cavity 05. During the process of the connecting rod 71 and the first locking block 73 moving from the limiting groove 61 into the mounting groove 6, due to the action of the locking inclined surface 76, the first locking block 73 moves closer to the connecting rod 71, and the locking spring 74 is gradually compressed. After the first locking block 73 disengages from the limiting groove 61, the locking spring 74 pushes the first locking block 73 to reset, and the side of the first locking block 73 abuts against the side of the mounting groove 6. At this time, the limiting plate 32 limits the car steering arm in the second cavity 05.

[0047] The first pushing assembly 4 includes a first pushing rod 41 fixed to the lower surface of the upper mold 03 and a first pushing inclined surface 42 disposed on the first pushing rod 41. The first pushing inclined surface 42 abuts against the end of the connecting rod 71. The first pushing inclined surface 42 on the first pushing rod 41 is used to push the connecting rod 71, which is located in the limiting groove 61, to move. When the upper mold 03 forges the workpiece in the second cavity 05, the upper mold 03 moves downward. The moving upper mold 03 drives the first pushing rod 41 to move downward. The first pushing rod 41 extends into the limiting groove 61 and then pushes the connecting rod 71 in the limiting groove 61 to move. During the movement of the connecting rod 71, it will drive the locking rod 72, the first locking block 73, and the limiting plate 32 fixed on the connecting rod 71 to move, so that the limiting plate 32 limits the car steering arm in the second cavity 05. During the movement of the connecting rod 71, the first locking block 73 on the connecting rod 71 moves from the limiting groove 61 to the mounting groove 6. The compressed locking spring 74 is reset. The first locking block 73 is blocked by the second locking block 75, and the reset spring 33 is in a compressed state. After the rotating plate 13 rotates 180 degrees, the opening of the second cavity 05 faces downward. The second pushing component 5 pushes the two first locking blocks 73 closer to each other. Then, under the action of the reset spring 33, the limiting plate 32 and the connecting rod 71 are pushed to reset. The first locking block 73 on the connecting rod 71 moves into the limiting groove 61. At this time, the limiting plate 32 no longer limits the car steering arm in the second cavity 05.

[0048] The second pushing assembly 5 includes a second pushing rod 51 fixed on the upper surface of the mold body 11 and a second pushing inclined surface 52 disposed on the first locking block 73. During the rotation of the rotating plate 13, the second pushing rod 51 will abut against the second pushing inclined surface 52 on the first locking block 73. During the continued rotation of the rotating plate 13, the second pushing rod 51 pushes the two first locking blocks 73 closer to each other. Then, under the action of the return spring 33, it pushes the limiting plate 32 and the connecting rod 71 to reset. The first locking block 73 on the connecting rod 71 moves into the limiting groove 61. At this time, the limiting plate 32 no longer limits the car steering arm in the second cavity 05, so the car steering arm in the second cavity 05 falls into the cutting chamber 06 under the action of gravity.

[0049] In this embodiment, in order to improve the limiting effect of the car steering arm in the second cavity 05, a plurality of limiting components 3 are provided on the rotating plate 13. Each limiting component 3 corresponds to a snap-fit ​​component 7, and each snap-fit ​​component 7 corresponds to a first pushing component 4 and a second pushing component 5.

[0050] The implementation principle of a forging equipment for manufacturing and processing automobile steering arms according to an embodiment of this application is as follows: When forging an automobile steering arm blank, the injection mold is first placed into the first cavity 04. The upper mold 03 moves down to forge the injection mold in the first cavity 04. Then, the drive assembly 02 drives the upper mold 03 to move up. The forged automobile steering arm blank in the first cavity 04 is taken out by the robot and placed into the second cavity 05. The drive assembly 02 drives the upper mold 03 to move down to forge the automobile steering arm blank in the second cavity 05. After forging, a ring of scrap will be formed on the surface of the automobile steering arm.

[0051] When the upper mold 03 forges the workpiece in the second cavity 05, the upper mold 03 moves downward. The moving upper mold 03 drives the first push rod 41 to move downward. The first push rod 41 extends into the limiting groove 61 and then pushes the connecting rod 71 in the limiting groove 61 to move. During the movement of the connecting rod 71, it will drive the locking rod 72, the first locking block 73, and the limiting plate 32 fixed on the connecting rod 71 to move, so that the limiting plate 32 limits the scrap material on the edge of the car steering arm in the second cavity 05. During the movement of the connecting rod 71, the first locking block 73 on the connecting rod 71 moves from the limiting groove 61 to the mounting groove 6. The compressed locking spring 74 returns to its original position. The first locking block 73 is blocked by the second locking block 75, and the return spring 33 is in a compressed state.

[0052] The drive assembly 02 moves the upper mold 03 upward, and the control assembly 2 drives the rotating plate 13 to rotate. During the rotation of the rotating plate 13, the second push rod 51 abuts against the second push inclined surface 52 on the first locking block 73. As the rotating plate 13 continues to rotate, the second push rod 51 pushes the two first locking blocks 73 closer to each other. Then, under the action of the return spring 33, the limit plate 32 and the connecting rod 71 are pushed to reset. The first locking block 73 on the connecting rod 71 moves into the limit groove 61. At this time, the limit plate 32 no longer limits the car steering arm in the second cavity 05. As a result, the car steering arm in the second cavity 05 falls into the cutting chamber 06 under the action of gravity. During the rotation of the rotating plate 13, the oxide scale in the second cavity 05 will also automatically fall off. In the subsequent forging process, there is no need to clean the oxide scale in the second cavity 05, thereby reducing the workload of the workers and improving the forging efficiency of the car steering arm.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
