Description

The percussion cutting-off machine

1, technical field

The present invention relates to a kind of shearing equipment or cutting implement, the percussion cutting-off machine that specifically a kind of explosive force that produces by powder burning is sheared reinforcing bar, steel plate or other hardwares.

2, technical background

Along with the development of modern architecture technology, in high-rise building or other skyscraper facility, use the reinforced concrete cast-in-situ construction more and more general, along with the rolled steel dosage in the increase concrete of depth of building also is multiplied.But whatsoever the building of sample and facility all have its service life, when service life at the end or all will be removed when in urban planning, needing to remove.Also have in natural calamity, in the war or destroyed in the terrorist incident.No matter under which kind of situation the building ruins of having collapsed are cleared up, all be will at first remove to clear up a large amount of reinforcing bars that are mixed in the broken concrete usually, be only then by building wastes such as charging appliance cleaning brick and tile stones.Like this, no matter be when building to the cut-out of various reinforcing bar materials or when removing to the cut-out of the reinforcing bars that tussle mutually in a large number, in its process, all become an important ring.

In the prior art, the method that the method for the reinforcing bar scrap in the building of caving in or hardware mainly is to use gas cutting or artificial hacksaw to cut apart is removed in cleaning, the existing in actual applications deficiency of above-mentioned two kinds of methods is that efficiency of construction is low, labour intensity big, dangerous big, cause problems such as industrial accident easily in the environment construction that is having flammable explosive gas to exist.At present, also do not have volume little, simple in structure, use flexibly, reinforcing bar or hardware that the cutting implement of high efficiency, safe ready is used for building concrete carry out THE ADIABATIC SHEAR IN, dismounting and cleaning.

3, summary of the invention

The purpose of this invention is to provide a kind of volume little, simple in structure, use flexibly, the percussion cutting-off machine of high efficiency, safe ready.

The objective of the invention is to realize in the following manner, objects such as reinforcing bar are placed cutting knife head cutter place, cocking, discharge striker, make its percussion boosting bullet under the motive force of bump spring, instantaneous burst power when ammunition is broken out is converted into the motive force of moment, promotes moving cutting knife with cut-outs such as reinforcing bars by piston.
