Description
Technical field
The invention belongs to the shearing equipment of sheet metal, relate in particular to a kind of multi-edge shear, this cutter is particularly suitable for the shearing to steel grating.
Background technology
Various sheet metals especially steel grating workbench, pedal, plank road, guard rail of being widely used in a lot of industries etc. are located.Steel grating is to be arranged by the certain spacing longitude and latitude by many rows load band steel and many horizontal rows bar to form grid-likely, and warp-wise is the load band steel, and promptly the length direction of steel grating generally adopts strip steel plate, and broadwise is a cross bar, i.e. the width of steel grating.Steel grating is welded via the automatic pressure bonding machine by the above-mentioned many row's strip steel plates and the quadrature many horizontal rows bar fried dough twist steel thereon that bear primary load, the area of the steel grating after the welding is very big, need actual size, steel grating is divided into the different length size according to the field of employment.
In metallurgy industry, the equipment that can cut apart several piece and even tens of blocks of strip metal sheet materials in a process cycles there is certain demand.In history, once there was multiple splitting equipment to attempt finishing this and cut apart work, as equipment such as milling, oxy-acetylene flame, laser, flame passes.Yet, be limited to a variety of causes, mostly rest on experimental stage, be difficult to become the consistent process equipment that adopts in the industry.Adopt sawing and grinding as the above-mentioned leading technology of cutting apart work, so circular sawing machine, band sawing machine and abrasive wheel cutting machine are propagated its belief on a large scale in the industry cutting apart of steel grating in the current industry.Sawing and grinding not only cost of charp tool height, efficient is low, power consumption is big, and cutting object can not be divided into two, and can only one be divided into three, these ＂ three ＂ are wherein cut apart byproduct--metallic dust, waste material become the helpless of this leading technology.Metallic dust flies upward scaling loss in air, be broom-shaped spark, causes serious air pollution and harsh noise, and the infringement operator's is healthy.Saw blade adopts the manufacturing of specific alloy steel, is to cause one of high reason of cost.
At aforementioned present situation, it is that the Chinese invention patent " a kind of steel grating shear " of ZL200810013873.0 (publication number is CN101219487Y) has disclosed a kind of like this steel grating shear that one application number is arranged, be by frame, lowering or hoisting gear, vertical shaft and clamper are formed, the bottom of lowering or hoisting gear is fixed with cutter, cutter can stretch between two row's clampers and the extended lower limb that surpasses clamper in its leg-of-mutton base, the head of cutter is a triangle, cutter can be one and more than, has the gap between adjacent cutter, lowering or hoisting gear is fluid pressure type or electric motor type, and the present invention has long service life, cutting process can not cause waste of material, there is not noise, the production efficiency height, simple in structure, the characteristics that production cost is low.
In aforementioned patent, the cutter head shape triangular in shape that is used to shear.Thereby the height dimension of cutter is inevitable very big, and then causes the lowering or hoisting gear stroke very long, so the cost height, efficient is low can hardly be avoided.Object--the load band steel intensity of steel grating is higher owing to being sheared, need bigger shearing force it could be cut off, when in cutter inserts the interval of steel grating from top to bottom, removing the shear-loaded band steel, at first the contact load band steel is the tip position of cutter, allow the long-pending cutter of small bore like this bear so big shear-type load, the tip position is easy to fracture.As adopt the method reply that improves material, increases thickness, then further strengthened the cost of cutter again.Aforementioned patent is still the shearing of steel grating cutting object one is divided into three, and waste material is not second to sawing technology.As will implementing aforementioned patent, it then is impassable obstacle that the precision of arranging of steel grating band steel is difficult to mate with the precision of arranging of sandwich device folder mouthful.
