Description
Technical field
The utility model relates to a kind of bar cropper, is related specifically to one, can make the cutting machine that reinforcing bar otch is level and smooth.
Background technology
Along with low-carbon alloy steel is in the application of architectural engineering, mechanical connection more and more finds broad application, especially straight screw connection, adopt hard rolling, its intensity is better than mother metal, and joint adopts high-strength screw shell to be connected with mother metal, easy to operate, speed is fast, cost is low, saving steel.But be difficult to control straight thread silk head quality of connection in construction, the section and the axis perpendicular that ensure reinforcing bar otch is difficult to when Steel Reinforcing Bar Material.If adopt abrasive wheel cutting machine directly to cut, greatly, labour intensity is large, and cutting speed is slow, cost is high for dust and noise pollution.And adopting GQ40 or the direct blanking of 50 type cutting machine, reinforcing bar port position is easily in the shape of a hoof.In order to ensure bar cutting rear port quality, increase work efficiency, reduce production cost, through repeatedly studying, the cutting blade of GQ40 or 50 type cutting machines being improved, carries out bar cutting, the shape of a hoof of reinforcing bar port disappears, reduce production cost, improve production efficiency, ensure that bar connecting construction quality, when original GQ40 or 50 type cutting machines cut off reinforcing bar, shearing force suffered by reinforcing bar is by some shear extensions to face, and it is large that local is subject to shear force, and mechanical load is large.Reinforcing bar is in shear history, and cutter contact side, the face of cylinder with reinforcing bar, and local pressure effect is large, and reinforcing steel bar bear is out of shape, and easily forms facet, is commonly called as the shape of a hoof.Interconnection technique regulatory requirements section is circular or close to circular, round diameter is greater than the pitch diameter of thread, and the form of thread of such roll extrusion is satisfactory, and original cutting machine directly cuts off and cannot meet the demands.In order to increase contact surface, reducing partial cut active force, namely increasing Multi-contact, adopt the shearing of oblique sword, multiple-cutting-edge shearing etc., dispersing shear active force, eliminate end face horse tellurium shape, end face is circle closely.
Summary of the invention
Goal of the invention of the present utility model is: provide a kind of bar cropper, not only increases reinforcing bar and blade contact face, and reduces reinforcing bar cutting central diameter to displacement.Make appearance of fracture after cut-out, port is straight, without the shape of a hoof, and asymptotic circle.
For completing foregoing invention object, the utility model is achieved in that a kind of bar cropper, and it is by support, Hang Shi mechanism, fixed cutting tool and movable cutter; The walking mechanism stated is fixed on support, and described movable cutter is installed on walking mechanism, and described fixed cutting tool is installed on the opposite of movable cutter, the edge of a knife of fixed cutting tool and the edge of a knife mutual dislocation of movable cutter; It is characterized in that: described fixed cutting tool is made up of cutter mounting frame and fixed blade, and described fixed blade is installed on fixed cutting tool installing rack; Described fixed blade is provided with " V " font sheared edge upper, and described " V " font sheared edge is built in the centre position of blade; Described fixed cutting tool installing rack is made up of fixed mounting and installation compressing tablet, and described fixed mounting is provided with and the mount pin installed joined together by compressing tablet, installs compressing tablet and is provided with fixing pin-and-hole; Gu objective blade is installed on fixed mounting and installs between compressing tablet.
Do further refinement to technique scheme, " V " type notch depth of described fixed blade is 10mm.Described adds a diameter 10mm length the add thickness pad equal with blade height in fixed blade back.The overlapping 1-2mm in " V " end of the blade of movable blades and the blade of fixed blade.The blade of movable blades and the knife-edge gap of fixed blade control at 0.4-0.6mm.
10mm was reduced than originally owing to improving the rear two blade front end maximum spacings of blade installation.Therefore the model of cutting machine is selected must to determine according to the maximum bar diameter of required cut-out; GQ40 is selected during the reinforcing bar of general cut-out below diameter 30mm; GQ50 is selected when cutting off the reinforcing bar of below diameter 40mm; And die-cut blade trip must consistent with description (because find that the market traveled distance that has a lot of cutting machine to be known as 40mm only has 30mm, and the traveled distance of 50mm only has 40mm); To reinforced bar cutting machine be selected simultaneously, namely be with clutch.
Adjustment stroke is with active blade and the overlapping 1-2mm in " V " end improving blade; Gap adjustment is that the die-cut blade of adjustment controls at 0.4-0.6mm with improvement cutter knife-edge gap (two blade side gaps); Guarantee that two blades are not mutually engaged when identical; Blade fixation will be improved after stroke, gap are adjusted, in case blade loosens, partially exempt from blade displacement in reinforcing bar cutting process.

Detailed description of the invention
In order to further description improvement advantage of the present utility model, be further described below in conjunction with accompanying drawing:
As shown in the figure, a kind of bar cropper, it is by support, Hang Shi mechanism, fixed cutting tool and movable cutter; The walking mechanism stated is fixed on support, and described movable cutter is installed on walking mechanism, and described fixed cutting tool is installed on the opposite of movable cutter, the edge of a knife of fixed cutting tool and the edge of a knife mutual dislocation of movable cutter; Described fixed cutting tool is made up of cutter mounting frame and fixed blade, and described fixed blade is installed on fixed cutting tool installing rack; Described fixed blade is provided with " V " font sheared edge upper, and described " V " font sheared edge is built in the centre position of blade; Described fixed cutting tool installing rack is made up of fixed mounting and installation compressing tablet, and described fixed mounting is provided with and the mount pin installed joined together by compressing tablet, installs compressing tablet and is provided with fixing pin-and-hole; Gu objective blade is installed on fixed mounting and installs between compressing tablet.
The blade improved is arranged on the former stiff end blade position of cutting machine.Because " V " type notch depth of blade is 10mm, in order to ensure the stroke of blade, the lengths of rebar that a diameter 10mm length is equal with blade height is added in fixed blade back, or become the wide stick of 10mm with utilizing original old blade cuts, in adjustment stroke, adjustment stroke is with active blade and the overlapping 1-2mm in " V " end improving blade; Gap adjustment is that the die-cut blade of adjustment controls at 0.4-0.6mm with improvement cutter knife-edge gap (two blade side gaps); Guarantee that two blades are not mutually engaged when identical; Blade fixation will be improved after stroke, gap are adjusted, in case blade loosens, partially exempt from blade displacement in reinforcing bar cutting process.
After blade debugging, carry out trial cut and cut, through repeatedly cutting off, steel bar end face and reinforcing bar axes normal, and without the shape of a hoof, warpage, qualification rate is more than 98%.
Blade installs and qualified by inspection, drills, can carry out formal reinforcing bar cutting after operator skillfully gains the essentials after telling somebody what one's real intentions are to operator; The top mark of reinforcing bar operating desk is high more lower slightly than blade center; Longer reinforcing bar two people must lift and should first put into two blades, and reinforcing bar enters in blade " V " groove, and adjust required cut-out reinforcing bar length, one end can be stepped on clutch near the regulating block mixed up and run blade.
