SAMHOOR advantage of high-speed presses in aerospace

    In aerospace, high-speed stamping for material requirements are very strict. In ensuring the relative performance of the premise, the lighter weight of the material as possible, so that the application of aluminum to show its importance.

    In practical application, the user is made under their product features the following requirements: most of its aluminum products, and the processing of sheet thickness are concentrated in less than 1mm, thinnest to 0.3 ~ 0.4mm; the surface can not have scratches . Users studied abroad stamping equipment (such as turret punch press), find turret punch difficult to meet their demands, for the following reasons: firstly 0.4mm sheet metal processing for example, which requires a gap between the dies is 0.08mm ( bilateral upper and lower die mold gap is calculated as 20 percent of the processing thickness), since turret punch press tooling needs are mounted on the upper and lower turret, there is between the die and the die holder and die holder and the lower turret larger The fit tolerance, coupled between the upper and lower molds of the upper and lower turret is driven by rotation of the turret chain to ensure that, thus leading to the upper and lower molds of the city to conduct regular adjustment, combined with the cumulative multiple tolerances are unable to meet the mold clearance requirements when processing sheet, which is difficult to process sheet metal turret punch press (thickness d≤0.5mm) the main reason. Because the plate is always moving with the progress in the process between the upper and lower turret, lower surface friction plate and the mold on the lower turret and scratches occur, directly affect the appearance of the product, especially the processing and surface-sensitive mirror plate high value-added materials.

    For more than the actual requirements of users, high-speed presses SAMHOOR's very good to meet the user's requirements: a relatively wide first process of plate thickness, the maximum punch 5mm thick steel plate, has demonstrated the thinnest 0.02mm of processed copper. Why high-speed presses either processed sheet SAMHOOR planks can also be processed it? SAMHOOR mainly on high-speed presses and turret punch structure is essentially different: SAMHOOR is using linear mold library, no heavy turret, electro-hydraulic drive punch of the mold to form a rigid connection with the punching mechanism to force rollback, can withstand great eccentric load, the turret did not exist as multiple cumulative tolerance, so we can guarantee the clearance requirements needed for processing sheet; the same mold mounted in a straight line mold library, in the processing of the mold and the mold library on the plate is not in contact also it will not be like a turret that generate a lot of scratches. These unique advantages of the achievements of the aerospace field position SAMHOOR speed punch.
