[0032] like Figures 3 to 4 As shown, the longitudinal bending assembly 21 moves up and down toward the fixed base assembly 13, while the longitudinal pressing head 212 slides and is confined within the receiving space, bending the first support leg 31 to the vertical direction. The lifting motion component 214 is fixedly installed on the top of the gantry frame 12. Optionally, the lifting motion component 214 is existing technology, such as a hydraulic cylinder, electric push cylinder, or pneumatic cylinder, which will not be described in detail here.

[0033] The first bending assembly 22 is mounted on one side of the frame 1. The first bending assembly 22 includes a first telescopic member 223 and a first pressure block 222 mounted on the frame 1.

[0034] The gantry frame 12 has a horizontal hole, and the first telescopic shaft 221 slides in the horizontal hole. When the first bending assembly 22 moves translatably towards the movable seat assembly 14, it bends and fastens the first vertical support leg 31 to one side of the front-mounted engine bracket body 3. The first telescopic component 223 is fixedly installed on one side of the gantry frame 12. The first telescopic component 223 is connected to the intelligent control center via a wire, and automated program control is achieved using a PLC or industrial computer. Optionally, the first telescopic component 223 is existing technology, such as a hydraulic cylinder, electric push cylinder, or pneumatic cylinder, which will not be described in detail here.

The second bending assembly 23 includes a second telescopic member 233 and a second pressure block 232 installed on the frame 1. The second telescopic member 233 is provided with a telescopically movable second telescopic shaft 231, and the second pressure block 232 is installed on the second telescopic shaft 231. The sliding seat 142 of the movable seat assembly 14 is provided with a guide hole. The second pressure block 232 slidably defines the guide hole and slidably connects to the guide hole. The sliding direction of the second pressure block 232 is perpendicular to the protruding direction of the second support leg 32.

[0036] The second bending assembly 23 moves translatably towards the fixed base assembly 13, bending and fastening the second support leg 32 to the other side of the front-mounted engine bracket body 3.

Optionally, the second telescopic component 233 is existing technology, such as a hydraulic cylinder, electric push cylinder, or pneumatic cylinder, which will not be described in detail here.

[0037] The working process of the pressing device: The drive telescopic component 1434 drives the drive slider 1432 to move downward via the telescopic shaft 1431. When the drive slider 1432 moves downward, the wedge-shaped surface 1433 acts on the drive surface of the sliding seat 142, and the sliding seat 142 moves horizontally towards the fixed seat assembly 13 to clamp the main body 3 of the front bracket of the automobile engine, and the first support leg 31 enters the preset position. Then the longitudinal bending assembly 21 descends from the top of the gantry 12 and applies vertical pressure to the first support leg 31, bending it from a horizontal state to a vertical direction (pre-position).

[0038] Then the first bending component 22 is pushed horizontally forward, pressing the vertical first leg 31 toward one side of the bracket body and fastening it; then, the second bending component 23 moves in the opposite direction, simultaneously bending the second leg 32 and fastening it to the other side of the front bracket body 3 of the car engine, thus completing the bending and fixing of the first leg 31 and the second leg 32 of the front bracket body 3 of the car engine.

[0039] Then, the drive telescopic member 1434 drives the drive telescopic shaft 1431 to move upward. When the drive telescopic shaft 1431 moves upward, it drives the drive slider 1432 to move upward. When the drive slider 1432 moves upward, the wedge-shaped surface 1433 of the drive slider 1432 gradually moves away from the drive surface of the slide seat 142. Under the elastic restoring force of the elastic reset member 1435, the slide seat 142 moves away from the fixed seat assembly 13 and finally returns to its initial position.
