Because plate shape and steel plate sideslip, the clippings width is not of uniform size, a certain length range insied width may near or greater than 90mm, and guide groove inner minimum wide be 90mm, steel-fastening just takes place at this moment.When broken limit enters guide groove, bigger as windup-degree, even 90 degree, as long as broken hem width degree will block on short transverse near 60mm.
H1=40mm is cutting thin plate or blade clearance when adjusting slightly deviation, and broken end easily withstands the guide groove base plate, be subjected to the base plate reaction force, broken end portion can be upturned, and just withstands guide groove middle part front port upper cover plate forward when moving, and causes steel-fastening even knocks over upper cover plate.
K1=20mm, less than 20mm or when cutting than thin plate, head is easily scurried into the space between lower scissor blade end face and guide groove, causes steel-fastening at broken end portion width.When D1=30mm, broken end portion are thin narrower, broken limit easily scurry out make scrap cutter cut less than, or be stuck between guide groove outlet and the cutting edge and cause steel-fastening.
The material of former guide groove is 16Mn, and under the continuous impact and friction on broken limit, the very easily damaged scratch of guide groove causes steel-fastening, and service life is short.Circle shear cutting edge center and scrap cutter cutting edge centre distance are 2600mm, and the total length of monoblock type guide groove is near 3m, and it is bigger to make time error, and also are difficult for adjusting when installing, and the time that causes changing guide groove is longer, and scale error is also bigger.In addition, the monoblock type guide groove is also inconvenient to handling steel-fastening.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and the broken limit of a kind of split type circle shear rim charge guide groove is provided.
Scheme of the present utility model is: disconnect with the guide groove middle part and the guide groove rear portion of the anterior L shaped plate disjunctor of guide groove, bottom, guide groove middle part is rectangular rectangular slab, with the biside plate upper edge of base plate disjunctor be sweptback hypotenuse shape, two hypotenuse upper surfaces are coated with and are inverted U-shaped shape upper cover plate; Guide groove middle part rear port is less than guide groove rear portion front port, and guide groove rear port plane, middle part and front port plane, guide groove rear portion are in together on the space plane, and guide groove rear portion front port end face exceeds 20～30mm than guide groove middle part rear port upper cover plate end face; Be rectangular pyramid-shaped cavity guide groove rear body rear port width B 2=130～140mm, height H 2=70～80mm, the guide groove rear portion up and down on angular cut plane and the scrap cutter space tangent plane spacing of lower scissor blade roller correspondence position be D2=10～12mm; Guide groove front body L shaped plate bottom transverse slat upper surface and circle shear lower scissor blade roller apex height drop H2=70～80mm, transverse slat side end face and circle shear lower scissor blade roller lateral surface spacing K2=18～20mm.
Advantage of the present utility model is: the precision of each size when the two-part structure has guaranteed to make and install.Reduced the number of times of steel-fastening, the time of handling steel-fastening also greatly reduces.
