Description

A kind of bloom PCD appearance scrapers

Technical field

The utility model is related to technical field of mechanical processing, specially a kind of bloom PCD appearance scrapers.

Background technology

Traditional PCD scrapers are divided into thick knife and smart knife according to processing method, and conventional drag is because of midway tool changing and secondary clamping With the error of positioning so that since chipping allowance unevenness causes product surface aberration even item occur in rear process finishing passes Line, since chipping allowance is uneven, causes bite when tool sharpening to be distributed with processing resistance for high-accuracy product It differs greatly, accelerating the concentrated wear of cutting edge influences product appearance and size, is to be difficult to keep away for traditional bloom processing Exempt from it is thick, smart between the error that is formed with positioning of secondary clamping, so traditional PCD scraper major defects are embodied in, structure list One, processing is cumbersome, stability is poor, it is therefore desirable to a kind of bloom PCD appearance scrapers.

Utility model content

The purpose of this utility model is to provide a kind of bloom PCD appearance scrapers, have allowance uniform, processing cost Low, the high advantage of production efficiency solves the secondary clamping of PCD scrapers traditional in the prior art slightly, between essence and positioning shape At error, the problem that structure is single, processing is cumbersome, stability is poor.

To achieve the above object, the utility model provides the following technical solutions：A kind of bloom PCD appearance scrapers, including PCD Cutter hub and PCD blades, PCD cutter hubs periphery offer cutter hub edges of the periphery transition arc, and PCD cutter hub left ends offer smart knife Rake face and cutter hub transition chamfering, PCD cutter hub right ends offer transition chamfering；It is provided with PCD knives on the left of the PCD cutter hubs Piece；It is provided with thick knife PCD blades on front side of the upper surfaces of the PCD blades, thick knife the is provided on the upside of the left end of thick knife PCD blades The left end downside of one relief angle, thick knife PCD blades is provided with the second relief angle of thick knife, is set between thick knife PCD blades and PCD cutter hubs It is equipped with insert groove A；The left end of the PCD blades is provided with cutter hub empty avoiding；It is provided with smart knife on rear side of the lower end of the PCD blades The left end of PCD blades, smart knife PCD blades is provided with smart knife rake face, and smart knife first is provided on the upside of the left end of smart knife PCD blades The left end downside of relief angle, smart knife PCD blades is provided with the second relief angle of smart knife；The rear end of PCD blades offers cutter hub front end side Empty avoiding offers insert groove B between the lower end and PCD cutter hubs of PCD blades.

Preferably, the thick knife PCD blades are the preferable PCD material component of the larger toughness of granularity.

Preferably, the smart knife PCD blades are that granularity is smaller, the strong PCD material of wearability.

Preferably, the number of degrees of the thick knife PCD blade reliefs E are 4 ° -8 °, the number of degrees of smart knife PCD blade reliefs F are 3 ° - Between 6 °, thick knife PCD blade reliefs E is more than or equal to F2 ° or so of essence knife PCD blade reliefs.

Preferably, the thick knife PCD blades are roughing, and smart knife PCD blades are finishing and burnishing-in, PCD cutter hubs rear end D12 ° of empty avoiding.

Preferably, it is provided with certain safe distance G between the smart knife PCD blades and PCD cutter hubs.

Compared with prior art, the beneficial effects of the utility model are as follows：

This bloom PCD appearances scraper improves traditional PCD scrapers, and Roughing and fine machining PCD scrapers are integrated, will Two knives processing originally changes a knife into and processes, and overcomes because PCD scrapers are thick, the secondary clamping between essence is formed with positioning Error keeps allowance for finish more uniform, ensure that the appearance and size of high smooth product；Overall processing is simple, and stability is good, adds Work workpiece luminosity is good, saves production cost, improves the production efficiency of mechanical processing.
