Description

Technical Field

[0001] This utility model relates to the field of sheet pile technology, and in particular to a two-roller pre-bending machine device for sheet piles. Background Technology

[0002] Hot-rolled steel sheet piles are high-strength steel products manufactured through hot rolling processes, conforming to the national standard GB / T 20933-2014. Cross-sectional shapes include U-shaped, Z-shaped, and straight-web types. These products are mainly used in water conservancy projects, foundation pit support, bridge cofferdams, and rail transit construction, featuring high bending resistance, high construction efficiency, and reusability.

[0003] Due to their special cross-sectional dimensions, hot-rolled steel sheet piles contain significant internal stress in the base plate, sheet plate, and lugs during the rolling process. Furthermore, the cooling rate varies depending on the thickness of each part, resulting in inconsistent shrinkage effects.

[0004] During production, sheet piles may bend upwards while cooling on the cooling bed. This upward bending causes instability during transport to the cooling bed and makes it difficult to enter the straightening machine for straightening. This can lead to undesirable deformation during subsequent straightening, affecting product yield. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a two-roll pre-bending machine device for steel sheet piles. This device allows for a pre-bending of the steel sheet piles before they enter the cooling bed, reducing the stress on the steel sheet piles and enabling them to move smoothly on the cooling bed. This avoids difficulties in straightening and deformation during the straightening process, thereby improving both output and quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The driving structure includes a sliding sleeve slidably connected to the outer wall of the columns, a bearing seat 2 installed on the outer wall of the sliding sleeve on one side close to each other, a pressure roller 2 installed between the bearing seats 2, and a driving assembly provided at one end of the pressure roller 2.

[0008] Preferably, both the outer wall of the sliding sleeve and the outer wall of the column are provided with adjustment holes, and a screw rod is inserted into the adjustment hole at the overlap of the sliding sleeve and the column. A fixing plate is welded to the outer wall of the other end of the screw rod, and a nut is screwed onto the outer wall of the screw rod.

[0009] Preferably, both ends of the top outer wall of the bearing seat are equipped with stabilizing rods, and the top plate has stabilizing holes at the stabilizing rods. The outer wall of the stabilizing rods is slidably connected in the stabilizing holes, and the top plate has a movable opening at the pressure roller.

[0010] Preferably, the drive assembly includes a base, a second mounting hole opened at the center of the base, a second hydraulic cylinder installed in the second mounting hole, a mounting seat installed on the outer wall of the top of the second hydraulic cylinder, and a motor and reducer installed in the mounting seat.

[0011] Preferably, the motor output shaft is connected to the input end of the reducer, and the output end of the reducer is connected to one end of the pressure roller.

[0012] Preferably, a positioning rod is welded to the top outer wall of the base, and a positioning hole is opened at the positioning rod of the mounting base, with the outer wall of the positioning rod slidably connected in the positioning hole.
