Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0076] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0077] Example 1:

[0078] like Figure 1 As shown, this application embodiment provides a stamped automotive suspension control arm assembly, including a mounting plate 101, a plurality of ball joint mounting holes 102, a plurality of bushing mounting holes 103, and a connecting edge 104, characterized in that it further includes:

[0079] Several reinforcing ridges 105 are spaced apart on the mounting plate 101;

[0080] The connecting edge 104 is integrally formed on the edge of the mounting plate 101 and is formed in one step by stamping together with each reinforcing protrusion 105.

[0081] In this embodiment of the application, due to the above-mentioned structure, the connecting edge 104 and each reinforcing protrusion 105 serve to enhance the structural strength of the mounting plate 101, and are all formed by one-time stamping, which strengthens the structure of the connecting plate and facilitates manufacturing.

[0082] Example 2:

[0083] like Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes:

[0084] A stamping device is also disclosed, comprising a base 201, a support column 202, a top box 203, a linear actuator 204, a punch 205, and a cavity 206, characterized in that it further comprises:

[0085] The slot 207 is located at the bottom of the top box 203, allowing the punch 205 to be raised and lowered;

[0086] Cooling device 3 is used to cool the lower end of punch 205;

[0087] The cleaning device 4 is used to remove impurities from the lower surface and periphery of the punch 205.

[0088] A method for producing a stamped automotive suspension control arm assembly is also disclosed, including the following steps:

[0089] S1. Cut the board material to obtain a rough board blank;

[0090] S2. Punching to obtain a rough blank of mounting plate 101 with several ball head mounting holes 102 and several bushing mounting holes 103;

[0091] S3. Place the mounting plate 101 blank in the cavity 206, and the punch 205 descends to punch out the connecting edge 104 and several reinforcing protrusions 105 on the mounting plate 101 blank to obtain the stamped automobile suspension control arm assembly.

[0092] S4. The punch 205 rises, and the cooling device 3 is activated to dissipate heat from the lower end of the punch 205.

[0093] S5. The cleaning device 4 is activated to clean the lower end face and bottom of the peripheral wall of the punch 205.

[0094] S6. Remove the stamped automotive suspension control arm assembly formed in cavity 206, degrease, remove rust, and spray paint the surface to obtain the finished stamped automotive suspension control arm assembly.

[0095] In this embodiment of the application, due to the above-described structure and method, the punch 205 can punch the connecting edge 104 and each reinforcing protrusion 105 on the mounting plate 101 in one go. After the punching action is completed and the punch rises to the top, the cooling device 3 and the cleaning device 4 can cool down the punch 205 and clean its bottom surface and the lower part of its peripheral sidewalls to ensure that the lower surface of the punch 205 is clean and maintains a low temperature so that it will not deform due to temperature accumulation and affect the stamping accuracy.

[0096] Example 3:

[0097] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the cooling device 3 includes an annular shell 301, which is fixedly installed on the top of the inner cavity of the top box 203 and sleeved on the outside of the punch 205; a cooling flow channel 302, which is S-shaped and disposed inside the punch 205; a pair of connecting pipes 303, which are symmetrically fixedly installed on the inner peripheral wall of the annular shell 301, one end of which extends into the inner cavity of the annular shell 301, and the other end is connected to both ends of the cooling flow channel 302 when the punch 205 rises to the highest position; and a circulating pump 304, which is installed at one end of one of the connecting pipes 303 that extends into the inner cavity of the annular shell 301.

[0098] Furthermore, it also includes a pair of blocking grooves 305, symmetrically arranged in the middle of the punch 205, which are respectively connected to both ends of the cooling flow channel 302; a pair of floating blocks 306, which can be floated in the corresponding blocking grooves 305 by corresponding preload springs 307; a pair of limiting grooves 308, symmetrically arranged at the bottom of the inner peripheral wall of the annular shell 301; and a pair of stop blocks 309, which are respectively fixedly arranged at the bottom of the outer wall of each floating block 306 and can slide in the corresponding limiting grooves 308.

[0099] In this embodiment of the application, due to the above-described structure, when the punch 205 rises, a pair of stops 309 enter the corresponding limiting grooves 308. As the punch 205 continues to rise, the pair of stops 309 contact the top of the corresponding limiting grooves 308, each preload spring 307 is compressed, and a gap appears between the top of each floating block 306 and the top of the corresponding blocking groove 305. As the punch 205 rises, the gap increases until the punch 205 rises to the top position, and each floating block 306 completely descends below the port of the cooling channel 302 and the port of the connecting pipe 303. At this time, the upper part of each connecting pipe 303 and each blocking groove 305 is completely connected to both ends of the cooling channel 302. The circulation pump 304 is started, and the coolant inside the ring shell 301 enters from one end of the cooling channel 302 and exits from the other end through each connecting pipe 303 and each blocking groove 305, thereby reducing the temperature of the lower part of the punch 205.

[0100] When the punch 205 descends, the circulation pump 304 shuts down, and each preloaded spring 307 releases its elastic potential energy. As the lower end of the punch 205 descends, the gap between the top of each floating block 306 and the top of the corresponding blocking groove 305 narrows until the top of each floating block 306 is in complete contact with the top of the corresponding blocking groove 305. At this time, both ends of the cooling channel 302 are closed. As the punch 205 continues to descend, a pair of stops 309 also disengage from the corresponding limiting groove 308. The punch 205 continues to descend to perform the stamping operation.

[0101] Example 4:

[0102] like Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the cleaning device 4 includes a rotating cover 401, which is rotatably installed in the inner cavity of the top box 203 and sleeved on the outside of the punch 205; a rotating actuator 5, used to drive the rotating cover 401 to rotate; an exhaust chamber 402, which is disposed on the upper part of the rotating cover 401 and communicates with the inner cavity of the rotating cover 401 through multiple exhaust ports 403; and an air supply unit 6, which is used to discharge the airflow outside the inner cavity of the top box 203 after passing through the exhaust chamber 402, the exhaust ports 403 and the inner cavity of the rotating cover 401.

[0103] Furthermore, the rotary actuator 5 includes a mounting ring groove 501 disposed at the top of the slot 207; a gear ring 502 fixedly mounted at the bottom of the outer peripheral wall of the rotating cover 401 and located in the mounting ring groove 501; and a gear 503 driven by a motor 504 and meshing with the gear ring 502 for transmission.

[0104] Furthermore, the air supply unit 6 includes an annular cover 601, which is fixedly installed at the bottom of the annular shell 301, with its inner sidewall slidingly abutting against the outer sidewall of the rotating cover 401; a blower 602, whose outlet end is connected to the inner cavity of the annular cover 601 through an air supply pipe 608; a plurality of air inlets 603, spaced apart on the outer sidewall of the top of the rotating cover 401, connecting the exhaust chamber 402 and the inner cavity of the annular cover 601; an exhaust chamber 604, which is located inside the top box 203, surrounding the slot 207, and connected to the peripheral wall of the slot 207 through a plurality of vent holes 609; and an exhaust fan 605, whose inlet end is connected to the exhaust chamber 604 through an air inlet pipe 606, and whose exhaust end is connected to an exhaust pipe 607 extending out of the top box 203.

[0105] In this embodiment of the application, due to the above-described structure, when the lower end of the punch 205 completely enters the inner cavity of the top box 203 through the slot 207 and is located in the inner cavity of the rotating cover 401, the blower 602 operates, causing the airflow to pass through the air supply pipe 608, the inner cavity of the ring cover 601, each air inlet 603 and the exhaust chamber 402 in sequence, and then blown from each exhaust port 403 to the peripheral side wall of the punch 205. At the same time, the exhaust fan 605 operates, causing the airflow to pass over the impurities on the peripheral side wall and bottom wall of the punch 205, and then be discharged from the top box 203 through each vent 609, the discharge chamber 604, the air inlet pipe 606 and the discharge pipe 607. At the same time, the motor 504 operates, and through the cooperation of the gear 503 and the gear ring 502, the rotating cover 401 rotates, and the position of each exhaust port 403 changes, so that all parts of the lower part of the peripheral side wall of the punch 205 can directly contact the airflow, ensuring the removal effect of impurities.

[0106] The middle sections of the air supply pipe 608 and the exhaust pipe 607 are both S-shaped and located inside the annular shell 301. The airflow passing through them can cool the coolant inside the annular shell 301.

[0107] Example 5:

[0108] like Figure 2 and Figures 4 to 6As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the cleaning device 4 also includes a mounting groove 404, which is disposed through the lower side wall of the rotating cover 401; a swing arm 405, which is rotatably mounted in the mounting groove 404 via a hollow connecting column 406, with its inner end extending into the inner cavity of the rotating cover 401 and its outer end extending out of the rotating cover 401; a ventilation ring groove 407, which is disposed in the swing arm 405 and surrounds the hollow connecting column 406; a connecting hole 408, which is disposed on the hollow connecting column 406 and connects its inner cavity to the ventilation ring groove 407; an exhaust main pipe 409, which is disposed in the swing arm 405 and connects to the top surface of the inner end of the swing arm 405 via multiple exhaust branch pipes 410; and a swing control unit 7, which cooperates with the outer end of the swing arm 405 to control the swing of the swing arm 405, with the top end of the hollow connecting column 406 open and its inner cavity connected to the exhaust chamber 402.

[0109] Furthermore, the swing control unit 7 includes a ring edge 701, which is fixedly installed at the bottom of the inner cavity of the top box 203 and surrounds the rotating cover 401; a blocking surface 702, which protrudes inwardly on one side of the inner peripheral wall of the ring edge 701; a fixing block 703, which is fixedly installed on the outer wall of the hollow connecting column 406; a moving block 704, which is fixedly installed on the top surface of the middle part of the swing arm 405; an arc-shaped limiting rod 705, one end of which is fixedly installed on one end of the fixing block 703, and the other end is movably inserted into the moving block 704; and a return spring 706, which is sleeved on the outside of the arc-shaped limiting rod 705, with both ends abutting against the adjacent end faces of the fixing block 703 and the moving block 704 respectively. When the outer end of the swing arm 405 contacts the blocking surface 702, its inner end moves into the mounting groove 404.

[0110] In this embodiment of the application, due to the above-described structure, during the lifting and lowering process of the punch 205, the outer end of the swing arm 405 contacts the blocking surface 702, and the inner end of the swing arm 405 is located in the mounting groove 404. At this time, the distance between the adjacent end faces of the fixed block 703 and the moving block 704 is minimal, and the return spring 706 is compressed to its shortest length. When the punch 205 rises to the point where its end face is higher than the top surface of the swing arm 405, and the rotating cover 401 rotates under the drive of the rotating actuator 5, the return spring 706 releases its elastic potential energy, pushes the moving block 704, and drives the swing arm 405 to rotate around the periphery of the hollow connecting column 406, causing the outer end of the swing arm 405 to disengage from the blocking surface 702, and its inner end to extend into the inner cavity of the rotating cover 401 and move to... Below the punch 205, some of the airflow entering the exhaust chamber 402 will pass through the inner cavity of the hollow connecting column 406, the connecting hole 408, the ventilation ring groove 407 and the exhaust main pipe 409 in sequence, and then blow from each exhaust branch pipe 410 to the bottom of the punch 205. As the rotating cover 401 rotates, the movement trajectory of the inner end of the swing arm 405 completely covers the bottom of the punch 205, so that multiple airflows can fully contact the bottom surface of the punch 205, ensuring the impurity removal and cooling effect. After the rotating cover 401 rotates one revolution, during the process of the outer end of the swing arm 405 moving to the blocking surface 702, the swing arm 405 and the moving block 704 rotate around the hollow connecting column 406, so that the return spring 706 is compressed and shortened, and the inner end of the swing arm 405 also moves into the mounting groove 404.
