[0041] The technical solutions of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] Embodiment 1: as Figures 1-5As shown, a rotating and twisting device for connecting beams of automobile shock towers includes a continuous die 10, which is provided with multiple stations corresponding to processes such as edge pressing, twisting, and punching. This embodiment focuses on the basic structure of claim 1: a rotating and twisting mechanism 20 is arranged corresponding to the twisting station of the continuous die 10, which includes a bearing seat 21, and a set of opposite rotating twisting components 22 is rotatably arranged on the bearing seat 21. The twisting component 22 includes a connecting head arranged at the end of the rotating shaft, which is used for clamping the connecting beam, and a gear and rack assembly 23 for driving the rotating shaft to rotate. The rotating and twisting mechanism 20 further includes a first moving mechanism 24 for pushing the twisting component 22 to clamp or release the connecting beam. In actual operation, after the continuous die 10 receives the raw material, it first flattens the ends of the connecting beam at the edge pressing station, and then enters the twisting station, where the twisting component 22 clamps one or both ends of the connecting beam through the connecting head, and the gear and rack assembly 23 drives the rotating shaft to rotate, realizing the twisting deformation of a predetermined angle. The first moving mechanism 24 realizes clamping and releasing through linear movement, ensuring smooth switching of processes. This embodiment covers the core features of claim 1 and provides basic rotating and twisting functions.

[0043] Embodiment 2: Based on embodiment 1, further illustrate the structure optimization of claims 2-4. As shown, Figure 4 The rotating and twisting mechanism 20 includes a first bottom plate 25 fixedly connected with the bearing seat 21, and the first bottom plate 25 is provided with a first driving cylinder 26 for driving the first bottom plate 25 to rise and fall, so that the twisting component 22 approaches or moves away from the connecting beam in the vertical direction, realizing the switching of the clamping state. The device further includes a rack, the rack bottom of the gear and rack assembly 23 is fixedly connected with the rack, and the rack is slidingly connected on the bearing seat 21, ensuring that the rack remains stable when the bearing seat moves, providing reliable rotating drive. The first moving mechanism 24 includes a second bottom plate fixedly connected with the rack, and the first bottom plate 25 is slidingly connected with the second bottom plate and driven to slide by a second driving cylinder 27, realizing the approaching / away movement in the horizontal direction. In this embodiment, the first driving cylinder 26 and the second driving cylinder 27 work cooperatively: first, the second driving cylinder 27 pushes the first bottom plate 25 to move horizontally to the connecting beam position, then the first driving cylinder 26 lifts the bearing seat 21 to make the connecting head clamp the connecting beam, and finally the gear and rack assembly 23 drives the twisting. This variant improves the flexibility and precision of the device, and is suitable for processing connecting beams of different sizes.

[0044] Embodiment 3: Based on the foregoing embodiments, further integrate the carrying mechanism of claims 5-7. As shown, Figure 2As shown, the device also includes a connecting beam transport mechanism 30, comprising a mounting back plate 31. The mounting back plate 31 has multiple sets of grippers, including a set of loading grippers, multiple sets of translational grippers, and a set of unloading grippers. The mounting back plate 31 is equipped with two sets of translational drive devices for driving the loading and unloading grippers to move horizontally. Each set of grippers has two grippers for simultaneously gripping two symmetrical connecting beams (such as a left connecting beam and a right connecting beam). The connecting beam transport mechanism 30 also includes a second moving mechanism 32 for driving the mounting back plate 31 to rise, fall, and translate. In operation, the loading grippers grip a pair of connecting beams from the raw material area and translate them to the pressing station of the continuous die 10; the translational grippers transfer workpieces between stations; and the unloading grippers remove the finished product. The second moving mechanism 32 uses a cylinder or motor to achieve the rising, falling, and translating of the mounting back plate 31, ensuring precise positioning of the grippers. This embodiment achieves parallel processing, doubling the output, covering all features of claims 5-7, and supporting continuous production.

[0045] Example 4: This example focuses on illustrating the rotational torsion process of claim 8, based on the apparatus of Example 1. For example... Figure 6 As shown, the process includes the following steps: S1, feeding the raw material to the pressing station of the continuous die 10, flattening both ends of the connecting beam to ensure the ends are flat for subsequent twisting; S2, feeding the flattened connecting beam into the twisting station, where the twisting component 22 engages at least one end of the connecting beam and drives the engaged end to rotate and twist relative to the longitudinal axis of the connecting beam at a predetermined angle (e.g., 45° or 90°); S3, feeding the twisted end into the next stamping station for end stamping, such as punching or trimming; S4, feeding the connecting beam into the next stamping station for end stamping of the other end; S5, unloading to obtain the finished connecting beam. This process is completed sequentially within the continuous die 10 with a fixed step feed, each step taking approximately 5-10 seconds, achieving cycle-based production. This embodiment emphasizes the flexibility of single-end or double-end twisting, suitable for connecting beam designs of different vehicle models.

[0046] Example 5: Based on Example 4, further illustrate the process details of claim 9. In step S2, the twisting assembly 22 is driven by the gear rack assembly 23 to rotate the shaft synchronously to implement the twist, ensuring that the twist angles at both ends are consistent, avoiding stress concentration; the first driving cylinder 26 drives the first bottom plate 25 fixedly connected with the bearing seat 21 to lift, so that the twisting assembly 22 switches between clamping and releasing the connecting beam, for example, lifting to clamp and lowering to release; the first moving mechanism 24 is used to push the twisting assembly 22 to move linearly close to / distance from the connecting beam to complete clamping and releasing. Specific operation: the second driving cylinder 27 pushes the first bottom plate 25 to approach the connecting beam, the first driving cylinder 26 lifts the bearing seat 21 to clamp, and then the gear rack assembly 23 rotates to twist, and finally releases in reverse order. This example combines the structures of claims 2-4 to illustrate the coordination of the cylinder and the rack to ensure that the twist precision is within ±1°.

[0047] Example 6: Based on the previous process examples, further illustrate the automation production integration of claim 10. Steps S1 to S5 are completed in the continuous die 10 in step increments and are transferred by the loading clamps, translation clamps and unloading clamps of the connecting beam handling mechanism 30; the handling mechanism 30 drives the installation back plate 31 to realize lifting and translation through the second moving mechanism 32, each set of clamps contains two clamps to synchronously grab and process a pair of left and right symmetric connecting beams in parallel, thereby realizing continuous and beat automatic production. Specifically, the loading clamps grab a pair of connecting beams and place them into the edge pressing station, the translation clamps transfer between the twisting and stamping stations, and the unloading clamps remove the finished products; the second moving mechanism 32 can be driven by a servo motor to ensure that the transfer precision is within 0.1 mm. This example covers the combination of claims 5-7 and the process to realize an automatic production line with a daily output of more than 1000 pieces.

[0048] Example 7: This example provides a variant process combining all the features of claims 1-10 for high-strength connecting beam processing. On the basis of the device, a sensor is added to monitor the twist angle; in the process, step S2 can choose single-end twisting (clamping one end only) or double-end twisting (clamping both ends), and the actions of the first driving cylinder 26, the second driving cylinder 27 and the second moving mechanism 32 are coordinated through the PLC control system. The clamps of the handling mechanism 30 use pneumatic clamping to ensure uniform gripping force. In practical applications, this variant is suitable for aluminum alloy connecting beams, the twist angle can be adjusted to 120°, and the efficiency is improved by 30% by processing a pair of connecting beams in parallel. This example fully verifies the compatibility and expandability of the device and the process.

The technical scope of the present application is not limited to the content of the specification, and the technical scope must be determined according to the scope of claims.
