The specific combination relationship is that the two sets of longitudinal support columns 2 are respectively set at both ends of the transverse main beam 1 to play a supporting role, and the transverse main beam 1 and the longitudinal support column 2 are perpendicular to each other, forming a rectangular rigid structure.
[0036] And such Figure 2 As shown, in this embodiment, the number of jacks 3 is several sets, which can be detachably connected along the transverse main beam 1 according to actual usage requirements, and are used to apply pressure to large components.
[0037] Meanwhile, in order to ensure that the plasticity of large components meets the requirements, the cable assembly is also provided in this embodiment. Its specific structure includes several sets of adjustable cables 4 and anchor points 5 set on the gantry frame, which are used to apply tension to the large components.
[0038] Furthermore, in order to ensure that the large component conforms to the design drawings during the forming process, the monitoring unit, including displacement sensors and pressure sensors, is also provided in this embodiment to transmit the deformation and external force data of the large component.
[0039] Finally, by setting up the control unit, which is electrically connected to the jack 3, the cable assembly and the monitoring unit, the magnitude and direction of the force applied to the large component are dynamically adjusted according to the data of the monitoring unit, so as to achieve flexible control of the forming force and ensure that the forming of the large component meets the requirements of the drawing.
[0040] Preferably, in order to adapt to the forming requirements of components of different sizes, the structure of the gantry frame is further defined. In this embodiment, the transverse main beam 1 and the longitudinal support column 2 are telescopic structures that can be adaptively adjusted according to the size of the components. Specifically, the height and width of the gantry frame are adjusted by hydraulic or electric drive devices.
[0041] Preferably, in order to meet the different requirements of applying pressure loads, the specific types of the jacks 3 are specifically defined. In this embodiment, the specific types of the jacks 3 are hydraulic jacks and servo electric jacks. The hydraulic jacks are used to quickly apply large loads, and the servo electric jacks are used for high-precision fine adjustment, so as to realize the loading of different loads on large components and meet the pressing requirements.
[0042] Preferably, in order to better achieve the plasticity of large components, the anchor point 5 is further defined. In this embodiment, the anchor point 5 can be movably set on the gantry frame. During use, the operator can flexibly set the position of the anchor point 5 on the gantry frame according to the specific shape of the large component, so that during the pressing process, the cable assembly can always apply external force to the large component for plasticity.

When the deformation of a large component exceeds a preset threshold or the load of the jack 3 component or the cable component is abnormal, the safety protection module 6 controls the control unit to trigger an emergency stop and alarm to meet the requirements of safe production and protect the safety of the forming tooling.
[0046] Furthermore, the specific type of the safety protection module 6 described in this embodiment is further defined. The safety protection module 6 includes an overload protector and an audible and visual alarm. The overload protector is connected to the jack 3 and the cable assembly. When the deformation of a large component exceeds a preset threshold or the load on the jack 3 assembly or the cable assembly is abnormal, the overload protector will stop the operation by connecting to the programmable logic controller and control the audible and visual alarm to alert the operator.
[0047] As a preferred option, such as Figure 3 As shown, when large components are difficult to move, in order to better perform the pressing process of welding large components, the specific structure of the longitudinal support column 2 in the embodiment is further defined.
