The lower support module 11 on the right side of the support groove 9 has a concave support platform 5. The bottom of the upper pressing module 12 has a concave pressing groove 2. The top width of the pressing groove 2 is equal to the thickness of the flange 13. The left side wall of the pressing groove 2 is a vertical plane 3. The bottom right side of the pressing groove 2 has a concave lower pressing platform 4. The distance from the lower pressing platform 4 to the top of the pressing groove 2 is equal to the distance from the support platform 5 to the top of the support groove 9. The left side wall of the support groove 9 and the left side wall of the upper pressing module 12 are wedge-shaped surfaces 1 that cooperate with each other.

[0025] During center point alignment, place the web plate on the support platform and the flange plate in the support groove, with one side wall of the flange plate flush against vertical plane one. Then, move the upper pressure module downwards, engaging the two wedge-shaped surfaces. The upper pressure module moves smoothly downwards, and vertical plane one and vertical plane two engage to correct any deformed flange plate. The support platform and lower pressure platform engage to correct any deformed web plate. When the lower pressure platform and support platform engage and press firmly onto the web plate, the top surface of the pressure groove contacts the top of the flange plate, and vertical plane one and vertical plane two are close to the side walls of the flange plate. Position and press the web plate firmly in the center of the flange plate, completing the center point alignment, positioning, and pressing of one side of the flange plate. Welding can then proceed. This centering and pressing process is faster and more accurate.

[0026] The width of the support groove 9 gradually increases from top to bottom.

[0027] The right side wall of the pressure groove 2 is an inclined surface, and the width of the pressure groove 2 gradually increases from top to bottom.

[0028] The lower support module 11 on the right side of the support groove 9 is provided with an adjustment pad 6 at the top, a positioning protrusion 7 at the bottom of the adjustment pad 6, and a positioning groove 1 that mates with the positioning protrusion 7 on the lower support template. The adjustment pad 6 is fixed to the lower support module 11 by bolts, and the top of the adjustment pad 6 is the support platform 5.

The web plate is then lifted and placed vertically in the support groove using the overhead crane and lifting hook. The clamping cylinder is activated, which clamps the wing plate on the same side from the outside, making it close to the vertical plane one. Then, the traveling mechanism is moved to move the upper pressure plate to the upper support plate at the rear end. Then, the lower pressure cylinder is activated, driving the upper mold pressure plate to move downward. The two wedge surfaces cooperate, and the upper pressure module moves downward smoothly. The vertical plane one and vertical plane two cooperate to correct the deformed wing plate. The support platform and the lower pressure platform cooperate to correct the deformed web plate. When the lower pressure platform and the support platform cooperate to press the web plate, the top surface of the pressure groove contacts the top of the wing plate, and the vertical plane one and vertical plane two are close to the side walls of the wing plate. Position and press the web plate firmly in the middle of the wing plate, completing the center point alignment and positioning of one side of the wing plate, and then welding can begin. Centering and pressing is faster and more accurate. After welding at this position, the upper pressing module can be moved to the position of the next lower support module using the traveling mechanism for centering and pressing welding.

[0036] In addition, the adjusting pads on the two lower support modules can be selected to have different heights from one to three, and special-shaped workpieces can be processed, such as the I-beam with the left wing plate having an upper and lower width of 100 mm and the right wing plate having an upper and lower width of 120-160 mm. The thicknesses of the adjusting pads on the two sides can be selected to be different, and the I-beam can be center-point calibrated, which cannot be realized by the current tooling.
