    Deep Drawing Process MachineUpdate：2022-03-31     Hits：171
    Deep drawing products in our life, such as washbasins, aluminum pots, lunch boxes, car fuel tanks, car covers, stainless steel sink etc. All require metal drawing hydraulic presses. The metal parts drawing hydraulic press is mainly used for the deep drawing process of the sheet metal. The double action deep drawing hydraulic press has two moving beams inside and outside: the drawing moving beam and the blanking moving beam, both of which can be lowered rapidly at the same time when the mold is close. Start to descend slowly to close the mold, and then start to hold the pressure.
    The drawing process is a process of processing the blank into an open hollow part by means of a die. This is a cold stamping process. The metal part drawing hydraulic press can process and draw cylindrical, doorway, spherical, conical, rectangular and other shapes. Various irregular opening hollow parts. By cooperating with other stamping processes, products with complex shapes can be produced. The metal parts stretching hydraulic press can adjust the working pressure, pressing speed, and stroke range. There are two processes: constant pressure and fixed stroke. It can maintain pressure delay and automatically return. The ejector in the middle of the table can also be used as a hydraulic pad.

    As one of the main stamping processes, the stretching process of the metal parts stretching hydraulic press has a wide range of applications. This equipment is used for the stretching and forming of products, including stretching, re-stretching, reverse stretching and thinning. Stretching, etc.

    deep drawing press process

    Drawing processing: The plate is drawn into the cavity of the concave mold with the help of the pressing force of the platen device and the punch, making it a container with a bottom. The processing in which the sidewall of the container is parallel to the stretching direction belongs to pure stretching processing; while the stretching processing for conical (or pyramidal) containers, hemispherical containers and parabolic containers, etc., includes expansion processing.

    redrawing process

    Re-stretching: For workpieces that cannot be stretched at one time, it is necessary to stretch again to increase the depth of the molding container.

    Reverse drawing processing: reverse drawing of the stretched workpiece, the inner side of the workpiece becomes the outer side, and its outer diameter becomes smaller.

    Thinning and drawing processing: Extrude the already formed container into a cavity of a concave mold slightly smaller than the outer diameter of the container with the help of a punch. Make it smaller in outer diameter and thinner in wall thickness. This both eliminates wall thickness deviations and smoothes the surface of the container.
