Device for cutting structural steels
10722957 · 2020-07-28 ·

A cutting device for cutting a number of structural steels in series is disclosed. The cutting device may include a cutting mechanism coupled to an actuating mechanism, both mounted on a support frame. The cutting mechanism may include a stationary cutting member having a plurality of openings and a movable cutting member mounted in side-by-side abutment with the stationary cutting member. Each lateral opening on the stationary cutting member is aligned with the corresponding opening on the movable cutting member, thereby forming a single extended opening, which is capable of receiving a workpiece therein. The movable cutting member is movable relative to the stationary cutting member from a first position to a second position. As the movable cutting member moves, it moves the aligned openings of the individual cutting members out of alignment one after another thereby shearing the workpieces in the process.

ELECTRIC FUSE BOX OR JUNCTION BOX ASSEMBLY WITH A HIGH VOLTAGE ELECTRIC LINE CUTTER DEVICE

An electric fuse box or junction box assembly has a high voltage electric line cutter assembly inside an electric fuse box or junction box. The assembly has a box housing for connecting a plurality of electrical lines or connections to a power source. The housing has a pair of mounting stanchions for affixing the high voltage electric line cutter assembly with an electric current carrying busbar having a pair of stub ends. Each stub end of the busbar for carrying electric current from the power source to the plurality of electrical lines is secured to one of the mounting stanchions. Each mounting stanchion has an attachment platform for attaching and supporting the stub end of the busbar and an underlying chamber below the attachment platform for receiving exhaust gases generated when the high voltage electric line cutter assembly is activated.

APPARATUS FOR THE REMOVAL OF A CIRCULAR COLLAR SWAGE MOUNTED ON A CYLINDRICAL PROJECTION
20200147674 · 2020-05-14 ·

Apparatus is disclosed for attaching to a lockbolt via a swaged-mounted collar. The apparatus includes an element which permits relative movement between a cutting blade and an opposing surface so that the collar is held centrally within the apparatus during cutting.

CUTTING DEVICE

A cutting device having a spring that is compressed. After a firing pin retainer has travelled a predetermined path, a locking element is released. The release results in the spring being released, causing the firing pin to be accelerated and at the end to strike a percussion cap, whereby a pyrotechnic charge therein is ignited and thereby a delay element, if provided, is lit. This delay element regulates the delay time. Afterwards, an additional charge is ignited. The gas volume thus generated applies pressure to the cutting element. Above a certain pressure the shear pin shears off, causing the cutting element to be axially accelerated. The cutting element strikes the stop at high speed as a result of the acceleration, and penetrates into same. A connection to be cut, which is guided through an opening in front of the stop, is thereby severed.

High voltage electric line cutter device

An electric line cutter device for high voltage busbars has a two-part housing, a piston, an igniter and a busbar. The upper housing includes a cylinder, cuboid or prism chamber. The lower housing also includes a cylinder, cuboid or prism chamber. The piston is contained inside one of either the upper housing chamber or the lower housing chamber. Upon igniting the igniter, the piston breaks a portion of the busbar moving the piston and the portion of the busbar into the opposite chamber thereby stopping the electric current flow. The piston is at least partially formed as an insulator to prevent electric discharge. The piston design together with chamber design includes integrated squeeze areas and blow channels for the appearing arc. A channel system outside or from inside the piston allow the pyro gases to push the arc plasma into a filter system to cool down the gases.
