The purpose of this utility model is the further developing and improving of above-mentioned No. 03234979.3 Chinese patent of continuing, a kind of high efficiency, low cost are provided, cutter material is few, but knife bar length free adjustment, dress changes more convenient, can satisfy 10mm aperture part processing, realize the cutter of folder certainly of the changed the outfit cutter head of industrialization sharpening.
The purpose of this utility model can reach by following measure.Certainly the folder cutter of a kind of cutter head that changes the outfit that the utility model provides, has a separable cutter box in conjunction with knife bar, wherein said knife bar and cutter head are the overall structures that links into an integrated entity, and are inserted in movably in the rectangular strip cutter box through hole that is shaped on the elastic opening groove.
The end that rectangular strip cutter box described in the utility model deviates from open slot is a circular arc.
The fore-and-aft plane of the cutter box described in the utility model is shaped at least one standby screw that helps out.
The utility model has following beneficial effect than prior art.
The utility model is simple in structure, but knife bar head and cutter box standardization machining thereof, cutter box are reusable, can realize the industrialization tool sharpening, save the sharpening time of a large amount of cutter materials and cutter, and can reduce the consumption of a large amount of welding cutter hub materials and the artificial dependence of reduction tool sharpening technology.The utility model has not only solved the problem of the applicant in " screw machine presss from both sides interchangeable cutter head cutting tool " following part of 10mm aperture of preceding application cutter head screw strength deficiency, and provides condition for modern processing criterion.Reducing labor strength, the efficient of saving sharpening time, the aspect of raising labour efficiency generation is the most remarkable.The expense of using the utility model to save, can calculate by following formula: save every day * 20 yuan/hour * 100 workman ≈ of working hour expense reduce expenses for 270,000 first year; on 0.5 hour * every month 22 working days if comprise the cutter material expense of saving, the expense of year saving can reach 500,000 yuan.
Processing characteristics of the present utility model is better than the carbide chip clamped cutting bit.The chip area that cutter head is left does not have trip bolt to be stopped, the probability that iron filings twine is little, the part quality height that processes, and roughing and fine finishining all are fit to.Be higher than existing mechanical clamped cutting tool the service life of cutter head.
But the knife bar length free adjustment in the cutter box: as the matched in clearance of knife bar and cutter box employing hole axle, the cutting angle on the cutter head mainly is anterior angle and relief angle, is adjustable to the optimized cutting angle.
Make simply, convenient mounting and clamping, the elastic opening groove is reliable from folder property, and loosening resilience is fast, need not special fastened tools.
