Among the various types of hydraulic presses, four-column hydraulic presses and single-column hydraulic presses are the two most widely used types. Due to the large volume of consultations between these two hydraulic press customers. The function of the single-column hydraulic press and the four-column hydraulic press are compared below.

1. Single Column Hydraulic Press

The single-column hydraulic press is shown below, and the fuselage is a C-type single-arm structure.

The single-column hydraulic press is mainly suitable for the process of stretching, forming and pressing metal products. It can also process non-metallic materials, presses of powder metallurgy products, correction of shaft parts, press-fit of sleeve parts, and shaping and trimming of metal products. And other processes. Easy operation.

The single-column hydraulic press is mainly used for the calibration and press-fitting of shaft-tired sleeve parts, and can also be used for other process purposes.

The single-column hydraulic press can be operated in two ways: the handle and the pedal. The pressure of the device can be adjusted within the specified range. The stroke size can be controlled and the operation is relatively simple.

2. Four-Column Hydraulic Press

The four-column hydraulic press is shown in the following figure. The four-column hydraulic press adopts a four-column structure.

The four-column hydraulic press can be used for metal stamping, bending, stretching, extrusion and flanging, as well as press forming of materials. The single-column hydraulic press is mainly applied to the shaft parts, mainly the press-fit of the shaft parts and the correction of the profiles.

The multi-column hydraulic press is commonly referred to as a four-column hydraulic press. It has an independent power mechanism and an electrical system. It is controlled centrally by a button to achieve a single-cylinder semi-automatic cycle with adjustable working pressure and compression speed. According to the need, the test can be carried out within the stroke range, and two processing methods can be completed, namely constant pressure distance forming, pressure forming, pressure holding delay and automatic returning action.

The four-column hydraulic press has an independent power mechanism and electrical system, and it adopts centralized control of buttons to realize single-action semi-automatic cycle operation. The working pressure and punching speed of the machine tool are adjusted according to the needs of the stroke range, and the two process modes of constant pressure and programming are completed. After pressing, there is a pressure holding delay and self-control. Return to exercise.
