A blasting system facilitates the actuation of a plurality of programmable detonators according to a desired blasting pattern, to cause the discharge of a plurality of associated charges, by downloading to the detonators blasting information that can be automatically determined by a portable handheld unit that incorporates a positional detecting device, such as a GPS device. The blasting information for any given detonator can be determined by the handheld unit as a function of the distance and the direction of the movement of the unit to the detonator, and / or by the actual GPS location while at the site of the detonator. This automatic determination of blasting information, and particularly the delay times, based on the movement of the unit to the detonator, eliminates error prone human calculations of the delay times needed for multiple detonators at a blasting site. This simplifies the operations and procedures needed for achieving a desired blasting pattern, without sacrificing safety or quality.

A device and a method for shaping sheared edges on stamped or fine-blanked parts having a burr include at least one cutting stage and at least one forming stage. The forming stage includes a shaping punch which has a shaping region for smoothing the sheared edge of the outer or inner contour of the workpiece to the net shape and an embossing shoulder for mashing the burr of the outer or inner contour. The shaping punch is configured so that the shaping region initially bends the burr on the outer or inner contour away from the sheared edge, then seizes the sheared edge for widening, wherein the embossing shoulder of the shaping punch mashes the burr on the outer or inner contour when the widening on the workpiece has ended and flattens the embossing bead, created during mashing, during separating of the shaping punch from the workpiece.

Provided is a construction method for accurately embedding a water supply or water drainage casing pipe based on BIM and an aluminum alloy formwork. The construction method comprises the operation steps that 1, a model is built through the BIM technology, position collision checking of the water supply or water drainage casing pipe is conducted, and a water supply or water drainage casing pipe production drawing is deeply optimized and designed; 2, the aluminum alloy formwork of a floor or a wall or a beam where a pipeline passes through is designed through the BIM technology, and pipeline position information data are recorded and stored through a two-dimensional code; 3, the aluminum alloy formwork with a positioning clamp ring is produced according to the information model; 4, the aluminum alloy formwork of the floor or the wall or the beam is installed; and 5, concrete is poured into the floor or the wall or the beam, when the concrete strength meets the requirement, the aluminum alloy formwork is dismounted, and the water supply or water drainage casing pipe is accurately embedded in the concrete structure. The effect that pipelines on the floor are on the same straight line is ensured, and perpendicularity of later pipeline installation is ensured; pipelines on the beam or the wall can be on the same proper slope line, and gradient of later pipeline installation is ensured; and the pipelines can be installed at a time successfully, and rework caused by dimensional deviation is avoided.
