double action stretching hydraulic press

Body material selection of high quality alloy steel casting, after strict heat treatment, to ensure strength and toughness. The hydraulic system adopts internationally renowned brand hydraulic components to ensure efficient, stable and low-noise operation. The control system integrates PLC intelligent control and touch screen operation interface to realize automatic management such as parameter setting and fault diagnosis.

The hydraulic cylinder is made of high-strength alloy steel pipe, such as 42CrMo, the inner wall is precision machined and special wear-resistant treatment, which has good wear resistance and pressure resistance. The piston is made of high-strength aluminum alloy or high-quality carbon steel to ensure the hydraulic cylinder Efficient operation in high-pressure environment.

The die uses die steel with high hardness and high toughness, such as Cr12MoV, H13, etc. After quenching, tempering and other heat treatment processes, the die steel has a hardness of HRC58-62 and can withstand high pressure and friction in the double-acting stretching process. The automobile manufacturing field can produce automobile body covering parts, doors, engine covers and other parts. The aerospace field is used to process complex-shaped parts such as aircraft fuselage skin and engine covers, and the hardware industry, can make metal containers, tableware, lamps, etc.

The process flow of the double-acting stretching hydraulic press mainly covers the entire production process from material preparation, equipment debugging, stretch forming to product removal.

According to product requirements, select appropriate metal materials, such as stainless steel, aluminum, copper, etc., and use a shearing machine or punch to cut the bulk material into a size and shape suitable for stretch molding;

According to the shape and size of the product, select the appropriate mold and install it on the double-acting stretching hydraulic press, carry out no-load trial operation, and check whether the various functions of the equipment are normal. Before the stretching starts, the blank holder moving beam is lowered first, and the material edge is pressed on the mold to prevent the material edge from wrinkling during the stretching process. After the blank holder is completed, the stretching moving beam quickly approaches the workpiece, and then changes to slow stretching, after the stretching action is completed, the stretching beam shall be kept under a certain pressure for pressure holding delay to ensure that the material is fully shaped. After the pressure holding delay is completed, the stretching beam and the pressing beam shall be released and returned to the initial position respectively.
