Description

Steel pole blank cutter

Technical field

The invention belongs to Metal Cutting fracture field of mechanical technique, be specifically related to a kind of steel pole blank cutter.

Background technology

As is known in the industry, whether make the steel pipe still made for various boilers for the steel ball of building material industry and will use steel pole.As a example by making steel ball, before this length of 6m or even longer steel pole were cut off by required specification, such as the steel pole of 6m length is divided into two from middle position, become the short material of two each 3m length, it is re-introduced into heating furnace heating, then by rolling steel ball machine rolling balling-up after going out heating furnace, finally carry out quenching, being tempered.To make as a example by steel pipe, first cut disconnected for steel pole, reheat perforation, carry out the most successively annealing, cold rolling, cold-drawn and finished product heat treatment.

In prior art, tediously long steel pole is cut to according to the length needed by commonly used sawing mode, at least there is the drawback of the following aspects in sawing: one, spillage of material is big, cause the wasting of resources, the such as steel pole by a length of 6m and a diameter of 75 is sawed-off in the middle position of its length direction, and the gap of disc type saw blade i.e. kerf width is about about 4, then with 10,000 tons of calculating, material damages and reaches about 30 tons, causes cost to increase；Its two, cutting efficiency is low, and still as a example by the steel pole of a diameter of 75, every sawing time once is 20-25S, thus affects production efficiency；Its three, working space (sawing place) environmental pollution is serious because by circular saw to steel pole sawed-off during sawdust splash, there is the anxiety affecting online assignment personnel health；Its four, owing to circular saw can send, during sawed-off to steel pole, the cacophony making us being difficult to bear, thus sound pollution is extremely serious；Its five, sawblade-replacing is frequent, has both affected working performance, causes again saw blade consumption big and improve the disconnected of steel pole is cut into this；Its six, poor stability because once saw blade fragmentation throws away, personal safety can be affected；In addition, if to hardness (HRC) at the steel pole of about 60-65 by manual sawing, specifically: first saw out one logical cut channel of ring on the surface of steel pole and around the circumferencial direction of steel pole, it is forced to rupture by mechanical registeration cut channel pressure again, the most not only the operation intensity of workman is big, and efficiency cannot make us flattering.

The technical information about steel pole fracture can be seen in disclosed Chinese patent literature, such as application for a patent for invention publication number CN101417385A recommends there be " material fracturing method of round bar ", its fracture process can be found in 2nd section reciprocal of the Instructions Page 2 of this patent application, but this patent application scheme does not provide the concrete structure of used blank cutter.

" steel bar cutter " (the utility model notification number applied on the same day is CN201769056U) typically provided such as invention patent mandate notification number CN101947732B, explanation according to this patent specification the 0005th to 0012 section, objectively can embody the 0015th to the 0022 section of technique effect concluded, but still there is following shortcoming: one, owing to needing the right-hand member in frame to configure a decompressor separately, and the stamping machine rack of this decompressor significantly exceeds the upper surface of complete machine frame, thus result in decompressor and lose compact, and volume is big, it is unfavorable for fabrication and installation and maintenance；They are two years old, due to when fracture when steel pole (patent claims rod iron) is pressed by decompressor needs by the material pressing device arranged separately, one end of steel pole is pushed down, and the middle part of steel pole is supported on liftout fulcrum, by decompressor, the other end of steel pole is pressed again and make steel pole rupture, thus fracture cumbersome.And understanding according to the entire contents (including the signal of figure) of description, owing to material pressing device is by manual operations, thus the labor intensity of online assignment personnel is big and efficiency is low；Its three, owing to also needing in addition to the device that rotates in a circumferential direction by independent longitudinal pay-off feeding, and ensure the lifting of longitudinal pay-off, thus action link be many, complicated integral structure；They are four years old, owing to cutter sweep is positioned at outside frame, when steel pole is cut, on steel pole, a circle cut channel mouth (the 0012nd section of the 3rd to the 5th row of description) is cut out by operator's hand-held cutter sweep alignment shearing length mark, thus cutting operation is the most inconvenient, and the labor intensity of workman is the biggest.

The most typical " the steel pole upsetting off line of CUT " introduced such as invention patent mandate notification number CN102626864B, due to this patent formula relative to CN201769056U eliminate decompressor, material pressing device and by plasma cutting mechanism with frame, thus overall structure has simplified and without making plasma cutting mechanism cut steel pole in the manual mode that lifts.But owing to employing the crane of lift equally, thus action link is many and integrally-built terse degree is not enough to reach desired requirement.Additionally, due to need thoroughly to be cut off by whole steel pole by plasma cutting mechanism, thus cutting-off process the most tediously long (specifically can be found in 2nd section reciprocal of this patent specification last page)；Owing to plasma cutting mechanism often completes steel pole once cuts the direction displacement needed towards deviating from steel pole, again towards the direction return of steel pole when once cutting on entering, thus action link is complicated and affects cutting efficiency.

In addition, above-mentioned CN101947732B with CN102626864B there is also following logical fraud: when the steel pole awaiting cutting lifted by crane can not rotate in a circumferential direction with all of steel pole supporting device entirety contact time, so steel pole there will be the passive rotation phenomenon of circumference, both affect cutting efficiency, there is again the anxiety that steel pole is taken the least important seat at a square table (beating tiltedly) or even tumbled from crane.

For above-mentioned prior art, it is necessary rational modification in addition, has made positive and useful design for this applicant, defined technical scheme described below, and under taking secrecy provision, the plant area the applicant is simulated test, and result proves practicable.
