The four-column hydraulic press for sheet metal stretching is a commonly used model. It adopts a three-beam four-column structure. The fuselage consists of an upper beam, a sliding beam, a workbench, a hydraulic backing plate, a mandrel, an oil cylinder, a column, a liquid filling tank, and a limit mechanism. . Sheet metal stretching hydraulic press, metal sheet stretching machine 200 tons, 315 tons, 400 tons, 800 tons. The system adopts servo system control, and the stretching pressure, speed and displacement precision are well controlled to ensure that the stretched products are highly consistent. The equipment is equipped with a PLC programmable controller and a touch screen, which can intuitively view some data and make adjustments in a timely manner. The operation button of the hydraulic press is integrated on a movable button operation table, and its position can be moved freely within a certain distance range, which is convenient for operation.
The main body of the frame type thin plate stretching hydraulic press is frame type, but there are four guide columns in the frame, and the contact surface between the frame and the sliding beam is made of copper guide rails. This machine has good parallelism and high precision. Suitable for press forming of sheet metal. But the cost price of this kind of machine is also higher than the ordinary three-beam four-column structure. Sheet metal drawing hydraulic press, metal sheet drawing machine 200 tons 315 tons 400 tons 800 tons is not only suitable for deep drawing, but also can complete all stamping processes such as shallow drawing, blanking, flanging, etc., especially in the field of auto parts manufacturing It has a wide range of applications. If it is matched with corresponding molds, it can produce automobile body coverings, brake pads, fuel tanks, chassis, axle housings, bumpers, etc.
The sheet stretching hydraulic press in the four-column hydraulic press can be divided into a single-action stretching machine and a double-action stretching machine; the appearance and style of the two are similar, but the specific use functions and action steps are different. The single-action thin plate stretching machine is relatively simple. The main oil cylinder is pressed down to fit the mold, and it is formed at one time. This style and function are suitable for relatively simple and small-sized products. The double-action thin plate stretching machine simply means two single-actions, with two pressures up and down. Usually, the pressure of the four-column hydraulic press is relatively large, and it cooperates with the pressure of the lower cylinder to complete the stretching action of the product. The surface of the product is relatively smooth.
