Description

Technical Field

[0002] As the core component of the front fork steering mechanism, the electric vehicle steel bowl is the key to ensuring the vehicle's steering performance and driving safety. In the vehicle steering system, it is like the core joint in precision machinery, providing stable and reliable support for the steering action of the front fork.

[0003] When the driver controls the steering, the front fork will rotate smoothly around the steel bowl. The steel bowl, with its precise structural design and excellent stability, ensures that the steering action is executed accurately and correctly, allowing the driver to easily control the direction of the vehicle.

[0004] However, in the traditional processing method of electric vehicle steel bowls, metal billets are often stamped and forged at room temperature. Although this processing method can quickly realize the production and processing of steel bowls, it has many significant technical defects: (1) The metal blank at room temperature has high strength and hardness, which makes it difficult to deform. As a result, the forming accuracy of the steel bowl is difficult to guarantee, and it is very easy to have problems such as dimensional deviation and irregular shape. (2) The plasticity of metal blanks at room temperature is relatively poor. When subjected to large punching pressure, cracks are prone to appear on the edges and corners of the steel bowl. The cracks will seriously reduce the strength and bearing capacity of the steel bowl, affecting its sealing and service life, posing a huge safety hazard to electric vehicles during use and increasing the risk of accidents.

[0018] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 7 As shown, the problem that the steel bowl is prone to cracks and poor processing accuracy when the metal billet is processed by room temperature stamping and forging in the prior art can be solved by the following solution; In this embodiment, a multi-station precision forging equipment for electric vehicle steel bowls includes a conveyor platform 1 and a station mounting plate 11 arranged above the conveyor platform 1.

Combined with the precise coordination of the lower die 23, the material transfer of the conveyor belt 14, and the orderly reception of multiple storage seats 15, a multi-station collaborative processing system for liquid metal forming, multi-frequency forging of the steel bowl, and grinding of the ball mounting surface of the steel bowl is constructed. This system simplifies the production process, reduces the waiting time between each process, and realizes the rapid and non-destructive forming of the initial shape of the steel bowl, thereby improving the overall processing quality and efficiency of the electric vehicle steel bowl. The forming station 2 includes an upper mold 21 movably mounted on the station mounting plate 11. Support plates 22 are symmetrically fixed on both sides of the top of the conveying platform 1. A lower mold 23 is provided between the support plates 22 for cooperating with the upper mold 21 to perform pressure casting on the electric vehicle steel bowl. The upper mold 21 and the lower mold 23 are combined to realize the forming process of liquid metal, so as to achieve the rapid and non-destructive forming process of the initial shape of the steel bowl. The pressure casting can improve the forming quality. The multi-frequency forging station 3 includes a mounting frame 31 fixedly connected to the bottom of the station mounting plate 11, and a forging head 32 is provided on the mounting frame 31, which matches the steel bowl of the electric vehicle and performs multi-frequency impact. The residual heat after forming is used to provide a thermal environment for the forging deformation of the formed steel bowl during the multi-frequency impact forging process, further avoiding the generation of forging cracks. It can also effectively refine metal grains, comprehensively improve the strength, toughness and fatigue resistance of the material, thereby improving the processing quality of the electric vehicle steel bowl, as well as the piston block 33 that vibrates and strikes the lower mold 23. The forging head 32 is fixedly connected to a support rod that slides with the mounting frame 31, which is used to increase the stability of the reciprocating lifting motion of the forging head 32.

[0020] A support plate 12 is fixedly connected to the conveyor platform 1 for receiving and processing the conveyor belt 14, intermittently providing a stable supporting force for the storage seat 15, and rotatably connected to four groups of rotating rollers 13 distributed in a rectangular array. The conveyor belt 14 sliding on the top of the support plate 12 is transmission-connected between the rotating rollers 13, and a plurality of storage seats 15 matching the steel bowls of the electric vehicle are equidistantly installed on the conveyor belt 14, which are used for receiving and conveying the steel bowls after forming. The conveyor belt 14 is used to drive the multiple storage seats 15 to move their positions.

[0021] A number of protrusions (not shown) distributed in a circular array are installed on the annular outer wall of each rotating roller 13, and grooves (not shown) that cooperate with the protrusions are opened on the conveyor belt 14 to prevent relative sliding between the rotating roller 13 and the conveyor belt 14, thereby improving the accuracy of the position movement of each storage seat 15. The storage seat 15 is fixedly connected to the conveyor belt 14 by a plurality of linearly distributed screws to avoid interference with the rotation of the conveyor belt 14. A servo motor that drives the corresponding rotating roller 13 to rotate is installed on the conveyor platform 1 by bolts.

[0022] An electric push rod 16 is symmetrically fixedly installed between the work station mounting plate 11 and the conveyor platform 1. The electric push rod 16 drives the work station mounting plate 11 to move up and down, and the bottom of the work station mounting plate 11 is fixedly connected to a plurality of support rods 2 that slide with the conveyor platform 1 to increase the lifting and lowering stability of the work station mounting plate 11.

[0023] A first spring 24 is fixedly connected between the upper mold 21 and the work station mounting plate 11. A hollow tube 25 is fixedly connected to the top of the upper mold 21 and located on the outside of the first spring 24. A pipe sleeve 26 that slides with the hollow tube 25 is fixedly connected to the bottom of the work station mounting plate 11. Liquid metal is injected into the molding groove of the lower mold 23. The work station mounting plate 11 carries the upper mold 21 to move downward. With the cooperation of the first spring 24, the upper mold 21 and the lower mold 23 are prompted to perform elastic extrusion molding first. The hollow tube 25 and the pipe sleeve 26 are used to prevent the upper mold 21 from sliding offset and assist in the precise docking of the upper mold 21 and the lower mold 23 to improve the processing accuracy of the steel bowl.

[0024] A crankshaft 34 is rotatably mounted on the mounting frame 31, and a first connecting rod 35 rotatably connected to the crankshaft 34 is hingedly connected to the forging head 32. A drive motor for driving the crankshaft 34 is bolted to the mounting frame 31. After the electric vehicle steel bowl is formed, the electric push rod 16 carries the station mounting plate 11 upward, causing the upper mold 21 to separate from the lower mold 23, and the formed electric vehicle steel bowl is placed in the storage seat 15. The servo motor drives the corresponding rotating roller 13 to rotate, and the conveyor belt 14 carries the storage seat 15 to move, causing the formed electric vehicle steel bowl to move to the bottom of the forging head 32, and the elastic pressurized electric vehicle steel bowl is cast again. The driving motor drives the crankshaft 34 to rotate, and the rotating crankshaft 34 is combined with the first connecting rod 35 to drive the forging head 32 to perform a lifting reciprocating motion. The forging head 32 contacts the formed electric vehicle steel bowl with heat energy inside, and performs multi-frequency impact forging treatment to further refine the metal grains and improve the strength, toughness and fatigue resistance of the material.

[0025] The surface treatment station 4 includes a U-shaped seat 41 fixedly connected to the bottom of the station mounting plate 11, and a rotating motor is installed on the U-shaped seat 41. A shaft sleeve 42 is fixedly installed on the output shaft of the rotating motor, and a spline shaft 43 is slidably connected to the shaft sleeve 42. A grinding disc 44 is fixedly connected to the spline shaft 43; While liquid metal rapid prototyping and multi-frequency forging of the steel bowl are being carried out, the grinding disc 44 contacts the forged steel bowl, and the rotating motor, in combination with the shaft sleeve 42 and the spline shaft 43, drives the grinding disc 44 to rotate. A second spring 45 is fixedly connected between the grinding disc 44 and the shaft sleeve 42. Under the elastic force of the second spring 45, the auxiliary grinding disc 44 contacts the steel bowl, and the ball mounting surface of the steel bowl is surface-grinded.

[0026] Example 2: Please refer to Figure 4-Figure 6 As shown in the figure, the long casting cooling molding time leads to low overall processing efficiency, and it is difficult to quickly unload and transport the material after casting molding, and to fully utilize the molding waste heat. The following solutions can be used to solve the problem; The multi-frequency forging station 3 in this embodiment includes a mounting frame 31 fixedly connected to the bottom of the station mounting plate 11, and the mounting frame 31 is provided with a forging head 32 that matches the electric vehicle steel bowl and performs multi-frequency impact, and a piston block 33 that vibrates and knocks the lower mold 23. By vibrating and knocking the lower mold 23, the discharge of the internal gas of the liquid metal is effectively assisted, and the generation of internal bubbles after the steel bowl is formed is eliminated from the root, thereby ensuring the density of the internal structure of the steel bowl. The forging head 32 is fixedly connected to a support rod 1 that slides with the mounting frame 31.

[0027] The lower mold 23 is rotatably connected to the support plate 22 via a fixed rotating shaft, and a gear 27 is fixedly connected to the rotating shaft. A limit plate 28 and a tooth plate 29 are fixedly connected to the upper mold 21. During the lowering and extrusion process of the upper mold 21, the limit plate 28 on the upper mold 21 slides against one side of the lower mold 23 to ensure the horizontal state of the lower mold 23. A material anti-slip seat 210 is fixedly connected between the support plates 22 and slides with the lower mold 23. A material through-hole is opened at the bottom of the material anti-slip seat 210. The continuous upward movement of the upper mold 21 carried by the work station mounting plate 11 causes the tooth plate 29 to engage with the gear 27, and the limit plate 28 is synchronously distributed with the lower mold 23, causing the lower mold 23 to flip 180°. In the flipping process, combined with the material anti-falling seat 210, the formed electric vehicle steel bowl is caused to fall through the material port to the storage seat 15 directly below, so that rapid flipping, unloading and transfer forging processing can be achieved while the inside of the formed steel bowl contains more heat energy, further improving the continuity and efficiency of production.

[0028] A fixing sleeve 36 is fixedly connected to the mounting frame 31 and slides with the piston block 33. An elastic impact block is fixedly connected to one side of the piston block 33. A second connecting rod 37 is hingedly connected to the piston block 33 and is rotatably connected to the crankshaft 34. The driving motor drives the crankshaft 34 to rotate. The rotating crankshaft 34, in conjunction with the second connecting rod 37, drives the piston block 33 to reciprocate horizontally, causing the elastic impact block to strike the lower mold 23 multiple times, thereby assisting in the discharge of gas inside the liquid metal. An air cavity hole 211 is provided on the lower mold 23 and on the outside of its forming groove. When the fixed sleeve 36 is connected to the air cavity hole 211, the reciprocating piston block 33 cooperates with the fixed sleeve 36 to draw external air into the air cavity hole 211 multiple times and discharge it, further accelerating the cooling and forming speed of the liquid steel bowl and improving the overall processing efficiency of the steel bowl.

[0029] Example 3: Please refer to Figure 1-Figure 7 As shown, the present invention also proposes a method for using a multi-station precision forging equipment for electric vehicle steel bowls, comprising the following steps: Step 1: Liquid metal is injected into the forming groove of the lower mold 23. The electric push rod 16 drives the station mounting plate 11 to move downward. The station mounting plate 11 carries the upper mold 21, the forging head 32 and the grinding disc 44 to move downward synchronously. With the cooperation of the first spring 24, the upper mold 21 and the lower mold 23 are urged to perform elastic extrusion molding first. During the descending and extrusion process of the upper mold 21, the limit plate 28 on the upper mold 21 slides against one side of the lower mold 23 to ensure the horizontal state of the lower mold 23. Step 2: After the electric vehicle steel bowl is formed, the electric push rod 16 carries the station mounting plate 11 to move upward, causing the upper mold 21 to separate from the lower mold 23. Then, the station mounting plate 11 carries the upper mold 21 to continue to move upward, causing the tooth plate 29 to engage with the gear 27, and the limit plate 28 is synchronously distributed with the lower mold 23, causing the lower mold 23 to flip 180°. During the flipping process, combined with the material anti-falling seat 210, the formed electric vehicle steel bowl is caused to fall through the material outlet into the storage seat 15 directly below. Step 3: The station mounting plate 11 moves downward, and the toothed plate 29 and the gear 27 are combined to cause the lower mold 23 to reset and flip, and the servo motor drives the corresponding rotating roller 13 to rotate, and the conveyor belt 14 carries the storage seat 15 to move, causing the formed electric vehicle steel bowl to move to the bottom of the forging head 32, and the elastic pressurized electric vehicle steel bowl is cast again; The driving motor drives the crankshaft 34 to rotate. The rotating crankshaft 34, in conjunction with the first connecting rod 35 and the second connecting rod 37, respectively drives the forging head 32 to perform lifting reciprocating motion, and the piston block 33 to perform horizontal reciprocating motion. The forging head 32 contacts the formed electric vehicle steel bowl with heat energy inside, performing multi-frequency impact forging treatment, further refining the metal grains and improving the strength, toughness and fatigue resistance of the material. Step 4: During the reciprocating motion of the piston block 33, the elastic striking block strikes the lower die 23 multiple times, thereby assisting in the discharge of gas inside the liquid metal and eliminating the generation of bubbles inside the steel bowl after it is formed. When the fixed sleeve 36 is in communication with the air cavity hole 211, the reciprocating piston block 33 cooperates with the fixed sleeve 36 to draw external air into the air cavity hole 211 multiple times and discharge it, thereby accelerating the efficiency of cooling and forming the liquid steel bowl. The steel bowl is turned over and blanked during the period when more heat energy is contained inside the formed steel bowl, thereby facilitating the convenience of multi-frequency forging. Step 5: Repeat the above-mentioned process of unloading and conveying the formed steel bowl, and simultaneously carry out liquid metal rapid forming and multi-frequency forging of the steel bowl. The grinding disc 44 contacts the forged steel bowl, and the rotating motor is combined with the sleeve 42 and the spline shaft 43 to drive the grinding disc 44 to rotate. Under the elastic force of the second spring 45, the auxiliary grinding disc 44 contacts the steel bowl to perform surface grinding on the ball mounting surface of the steel bowl.
