[0002] The four-column hydraulic press is a mechanical equipment that uses hydraulic principles for processing. In a four-column hydraulic press, high pressure can be applied to the workpiece through at least one hydraulic cylinder to achieve deformation of the workpiece. This equipment is fixed by four columns, which can effectively ensure the stability and accuracy of processing. Its working principle is based on the incompressibility of liquid. When the hydraulic oil is pumped into the cylinder, the pressure is automatically transmitted to the hydraulic cylinder, so that the workpiece is subjected to high pressure. The pressure of the four-column hydraulic press can be adjusted by the pressure of the hydraulic pump to meet the workpiece processing needs of different industries.

[0003] In the current existing technology, when a four-column hydraulic press is used to punch out metal sheets of different shapes, the staff is required to manually adjust the position of the metal sheet so that the lower pressing die can punch out the metal sheet on the bottom die. This process requires the staff to manually adjust the position of the metal sheet, which makes the staff's labor intensity greater and is more time-consuming. Therefore, a four-column single-action thin plate stamping hydraulic press is proposed to solve the above problems. Utility Model Content

[0023] Among them, the two connecting plates 63 each include a side plate and a threaded sleeve. The two threaded sleeves are respectively fixedly installed inside the two side plates. The two threaded sleeves are respectively threadedly installed on the outer surface of the double-threaded rod 62 and are symmetrically distributed on the left and right, so that the double-threaded rod 62 can be rotated to control the two connecting plates 63 to move to the opposite side or the opposite side.

[0024] By adopting the above technical solution, it is possible to control the rotation of the double-threaded rod 62, so that the two connecting plates 63 threadedly connected to the outer surface of the double-threaded rod 62 move, and the two connecting plates 63 move to the opposite side on the outer surfaces of the two guide rods respectively, thereby controlling the two abutment plates 66 to move synchronously, so that the two moving abutment plates 66 fix the metal sheet to the top of the bottom mold 4.
