Longmen hydraulic press, also known as double column hydraulic press or Longmen hydraulic press, why choose a welded structure for the entire machine structure? Because the Longmen hydraulic press itself is based on the Longmen frame, the overall style structure is similar to the door frame. Therefore, in the support effect, the left and right arms serve as the support points for force. This design principle helps to increase the clearance of the operating space, allowing for the operation of large workpieces, making the pressing process more convenient and unobstructed. It is more suitable for the pressing and dismantling of bearing workpieces. Some workpieces are relatively large, and according to the structure, a mobile worktable can be selected. The front and rear equipment are driven by telescopic hydraulic cylinders, and the electric button operation switch control is simple and convenient. Therefore, placing the workpiece is relatively simple.

Longmen hydraulic press should have experience in welding skills, pay attention to the connection of welding points, and there should be no bright spots in the weld seam. After welding, the quality of the weld seam should be strictly inspected. Compared to other hydraulic press styles and structures, the double column hydraulic press has the advantage of spatial structure and can expand to a larger space scale. In terms of welding skills, there are techniques such as double protection welding and oxygen shielded arc welding. Among many welding skills, aerobic welding is a suitable equipment. This operation can directly and significantly connect steel, and the surface of the welding gap is smooth and scaly. Moreover, the rigid structure can meet the user's operational requirements.
