BLANKING SHOCK DAMPERS FOR PRESSES

Dampens noise. Reduces vibrations. Increases tool life. Protects presses.

SHOCK DAMPERS FOR PRESSES

 HYLATECHNIK Blanking Shock Dampers bring significant economic and environmental advantages to your press shop. At the instant of breakthrough in a blanking operation, press and dies are subjected to severe stress. Sooner or later this results in damage to bearings, seals, gibways, etc. and to increased die wear, or even punch breakage. By using HYLATECHNIK Blanking Shock Dampers, service life of press and blanking tools are substantially increased. Noise and vibrations are significantly reduced.

Advantages: Reduced noise and vibrations, increased tool life, press protection.

    BLANKING SHOCK DAMPERS – OPERATING PRINCIPLE

    In starting position the damper piston is fully extracted. The oil compartment of the cylinder is filled with oil. Force is applied to the piston by the press ram, and oil is expelled through one orifice or more. Before the blanking operation, the ram descends at normal speed and the orifice inside the damper causes only a low pressure rise inside the oil compartment. This adds only a relatively small load to the press. On breakthrough of the blanking punch, ram speed increases to a multiple value. The flow resistance across the orifice rises, causing high pressure inside the cylinder – the damping effect is produced.

    HYLATECHNIK BLANKING SHOCK DAMPERS ARE AVAILABLE IN THREE BASIC VERSIONS.

    • SHYC-H version with built-on tank
    • SHYC-S version for external oil supply in hydraulic presses
    • SHYC-M version for external oil supply in mechanical presses

    Where required, space saving or specially shaped non-standard versions (also with longer or shorter stroke) are supplied.
    Your specific enquiries are welcomed.

    A height adjustment can be supplied as an accessory.

    INSTALLATION, SET-UP

    Blanking Shock Dampers are installed symmetrically on the press table and have to be prevented from moving out of position (the cylinder housing has through-holes for mounting screws). The overall height of the damper has to be set in such a way, that it comes into contact with the ram just before the breakthrough occurs. To compensate for large differences in height, solid, machined spacing blocks are placed under the damping cylinders. The optional adjusting nut allows a fine adjustment within 30 mm. Each set of Blanking Shock Dampers are equipped with the orifice combination selected for the application. If it becomes necessary to alter the dampening effect, the orifice can easily be changed.
