Abstract

A steel wire broaching die device relates to the technique of mechanical process, with the broaching process, the tool carrier and the cutting tool can be replaced by the fixed high strength and high precision mould, and the speed of the steel wire strap can be increased. The height of the steel wire can be efficiently controlled (the error is only 0.005 mm in the entire plate), the quality of the blade edge (the error of the blade edge symmetry is smaller than 0.02, the surface roughness of the blade edge Ra 1.6, the sharpness of the blade edge and the blade edge platform are smaller than 0.03 mm, and the blade edge basically has not annealing phenomenon.) can also be controlled, so the qualified rate of the production is increased to more than 99%, and the excellent quality rate is increased to more than 95%. The production efficiency is increased (the productivity is 7 times higher than an edge grinding machine, and is 3 times higher than an edging machine.), and the utility model can be widely used in the industry of printing assembly.

Description

Steel wire broaching die device

Steel wire draws a mouthful die device, relates to the cutlery Machining Technology.

Steel wire is a strip book steel sheet alternate product, can make various shapings and cut mould, impression mould etc., is the necessary cutter of industry production cutting such as printing, system box, leather, clothes, shoemaking, packing or impression material.Its principal item generally has cutter line, garden mouth line and tooth trace etc.

At present, on steel wire product cutting edge processing technology, mostly adopt grinding and two kinds of methods of broaching both at home and abroad.Most manufacturers adopt grinding process, equipment for grinding is similar to the processing shaver, general edge polisher has bistrique 12-16 only, the bistrique rotating speed is 2880r/min, the steel band linear velocity is 1.7-2m/min, the advantage of this method is that the steel knife cutting edge is sharper, but its shortcoming is cutting edge differential annealing after grinding, and the product height error is big, whole dish steel knife (150m) error can reach 0.05-0.10, and production efficiency is low, also has minority manufacturer to adopt Broaching Technology, and general chipping edger has the knife rest Second Mate, steel band linear velocity V=120-140m/min during broaching, need 4-6 back and forth during broaching, the advantage of this method be production efficiency than the grinding height, the cutting edge light, material is squeezed during broaching, structure is tight, be difficult for getting rusty, but shortcoming is, the steel knife cutting edge also can produce differential annealing after broaching, the product height error is also bigger, whole dish steel knife error can reach 0.03-0.05, because repeatedly broaching back and forth, cutting edge quality is wayward.

The utility model is intended to provide a kind of steel wire and draws a mouthful die device, with control steel wire height, improves cutting edge quality and production efficiency, makes things convenient for practical operation.

The utility model also adopts Broaching Technology.Owing to chipping edger converted products poor quality's main reason is the influence of the intensity, precision, the feed screw nut that directly are subjected to tool rest carriage intensity, precision and the depth of cut size of paying, therefore design substitutes knife rest and cutter with the fixing high strength high-precision mold of a cover (3 to 6), reasonable distribution broaching amount is to improve the machining accuracy of product.The steel band linear velocity is brought up to V=180-230m/min from V=120-140m/min, and the best is 200m/min, has not only improved the broaching performance, also rises to operating efficiency simultaneously.

Formwork main body 3 is Contraband shape, the center, back has a through hole, steel band base bayonet socket 4 is put on the right side in the groove, screw by forward position on the right side of parts 3 is fixed, broaching tool 7 is put in the left side in the groove, screw by forward position on the left side of parts 3 is fixed, respectively there are two convex shoulders that run through the center, back of right pressing plate 5 and left pressing plate 8, be seated in two ends, the left and right sides on the groove of parts 3 respectively, press toward base bayonet socket 4 and broaching tool 7, use screw and parts 3 fixing, the height of formwork left plate 1 and right plate 6 equates with the height of parts 3, its width equates with the thickness of parts 3, uses screw to be fixed on the parts 3.Be equipped with backer 2 behind the broaching tool between the groove inside broach 7 of parts 3 and the left plate 1, so that broaching tool 7 advances simultaneously when regulating.

The logical screw of left plate 1 and center, right plate 6 side passes through adjustment screw, the square that left plate 1 adjustment screw can be regulated

bayonet socket

4 and 7 of broaching tools according to the differing heights of steel knife, different broaching amount from, the adjustment screw of right plate 6 makes definite value of installation site size maintenance of base bayonet socket 4.

The synthetic cutter that broaching tool 7 can be made up of two sheet cuttves also can be whole cutter, and whole cutter is the same with base bayonet socket 4, and afterbody has one 70 °-80 ° the gradient.

The through hole of center, main body 3 back can be a rectangle, can be long waist shaped, also can be ellipse garden shape or other shape, and effect is to pass through steel band.

The utility model obviously improves product quality, the product height can reach international advanced standard H ± 0.015mm, whole dish (150m) height error only is 0.005mm, cutting edge symmetry error ∠ 0.02, edge surface roughness Ra1.6, cutting edge sharpness, cutting edge platform ∠ 0.03mm, the essentially no annealing phenomenon of cutting edge, product percent of pass is brought up to more than 99% from 80%, and quality percentage is brought up to more than 95% from 30%.Productivity ratio is more than 7 times of edge polisher productivity ratio, is more than 3 times of chipping edger productivity ratio, has improved the competitiveness of product greatly.Benefit obvious unusually for printing apparatus manufacturer.
