Currently, the scale segmentation of fashioned iron can be divided into two classes, one kind is using shearing segmentation, and another kind of is using sawing point
Section.Wherein, shearing applies in general to the fashioned iron of small-sized simple section, cold saw be suitable in, large complicated section profiled bar
Scale segmentation.
Above two segmented mode respectively has advantage and disadvantage, wherein advantage is that end does not have using the fashioned iron of cut mode segmentation
Burr, but it is easy to cause fashioned iron Leading Edge Deformation, the serious normal use that will affect client；The type being segmented using cold saw
Steel, advantage are that section is smooth, will not generate Leading Edge Deformation, the disadvantage is that, in high speed cold saw sawing process, it can be formed in fashioned iron end
" burr ", this burr clearly require in " hot-rolled steel section " GB/T706-2016, i.e. regulation " fashioned iron end not Ying You great
In the burr of 5mm ".
The cleaning of fashioned iron end burr has following methods:
(1) method removed is broken by hand using artificial, this method cleaning efficiency is low, and has individual sites cleaning unclean,
It often has the burr greater than 5mm and is retained in fashioned iron end；
(2) the mating angle grinder method for cleaning of flame is used, this method cleaning is more thorough, but cleaning efficiency is low, cleaning
Spare part and cost of labor are higher；
(3) it is cleared up using angle grinder, this method cleaning is thorough, but efficiency is one kind minimum in method for cleaning, cannot
Effectively meet the requirement of serialization, fast pace production.
Utility model content
The utility model aim is to provide a kind of hydraulic shear for rejecting fashioned iron end burr, can effectively reject fashioned iron end

Cutting edge is positioned opposite, fixed to cut handle and be fixed on the cylinder body of hydraulic cylinder, and the piston rod of hydraulic cylinder is cut handle and be fixedly connected with dynamic, support
Arm is hinged on fixation and cuts on handle, and support arm is equipped with pretension support wheel close to dynamic one end for cutting handle.
It is mutually matched angle steel that the fixation, which cuts the outer cutting edge on handle and moves the interior cutting edge cut on handle,.
The interior cutting edge and outer cutting edge, which pass through fastening bolt respectively and be fixed on, dynamic cuts handle and fixation is cut on handle.
The other end of the support arm is pretension arm.
The support arm is equipped with suspension button.
Using the utility model, the pretension support wheel on support arm is pressed on fashioned iron surface first, and make fashioned iron
The burr of end face is placed between interior cutting edge and outer cutting edge, then operates hydraulic cylinder, and the piston rod of hydraulic cylinder is retracted, and drives dynamic cut
Outer cutting edge on handle is mobile, engages outer cutting edge and interior cutting edge, so that the burr of fashioned iron end face be cut off.
The beneficial effects of the utility model are: the burr of fashioned iron end can be rejected effectively, the burr after making shearing is high
Degree is not more than 2mm, meets customer and standard requirements.
