Description
Technical field
The present invention relates to a kind of screw thread process to manufacture field, and in particular to a kind of shaping side of carbide alloy screwed hole
Method.
Background technology
With the demand for development of modern industry, screw thread is widely used in connecting, seals, is driven, fastening etc..With hard
The various structural members of matter alloy production, wear part are equally more and more by the way of threaded connection, but hard alloy
High, the unmanageable feature with hardness, big to processing mode difficulty of processing such as screw thread progress electric spark, grindings, cost is high.With
The development of half material molding technology, turning, milling can be carried out to pressed compact, realize and half machine-shaping is carried out to non-accurate thread,
And half processing to accurate thread is prefabricated, substantially increases the processing efficiency of solid carbide thread, reduces processing cost.Spiral shell
Line milling has the features such as machining accuracy is high, high in machining efficiency, versatile, is applied to half process technology of solid carbide thread
In, its difficulty of processing can be substantially reduced.Therefore, I is taken charge of by experiment repeatedly, sums up this processing method.
The content of the invention
It is an object of the invention to provide a kind of forming method of carbide alloy screwed hole, in order to ensure product quality, carry
High efficiency, for difficult forming product we using the scheme of semi-finished product processing solve problem, i.e., by pressed compact
The improvement of density, the design of half process tool and improvement, the innovation of processing technology and production process quality control, realize that hard closes
The processing of gold shell pit.
The present invention is achieved like this, a kind of forming method of carbide alloy screwed hole, it is characterised in that method and step
It is as follows：
One, dispensing, using PEG as forming agent, raw material generates compound after adding alcohol to grind and being spray-dried；It is mixed with this
Close and expect that suppressing the pressed compact come has even density, the big advantage of compact strength；
Two, molding, compound is again by compressing；
Three, half adds, and by CNC milling machine, lathe or machining center, uses polycrystalline diamond（PCD）Dedicated tool, accurately
Thread size calculate, compacting base on processing with preset parameter screwed hole；The method compared to it is traditional with electric spark,
The processing modes such as grinding carry out solid carbide thread processing, greatly reduce difficulty of processing and processing cost, can meet common
Assemble the shaping of national standard screw thread；
Four, sintering, last sinter molding obtains required screwed hole.
Further, during the dispensing, using PEG as the forming agent of compound, compact strength is improved, can not had to pre-
Burning is directly processed；Avoid buildup in screwed hole simultaneously；Prior powder metallurgy produces, and pressed compact needs by pre-burning, reaches one
Fixed intensity could carry out semi-finished product processing.
Further, the density uniformity of base is suppressed, ensure that the stabilization and uniformity of sintering rear thread size.
Further, half bonus point is three drilling, chamfering, reaming, hole processing steps.Drilling：Using small straight
Footpath drill bit bores bottom outlet, because drill bit hole surface is relatively rough, it requires that the bottom diameter that drill bit drills out is less than screw thread
The path of design.Chamfering：Using rose reamer chamfering.Prevent the breach of edge-wise threads.Reaming：Using straight shank milling cutter, expand drill bit
The endoporus processed, bore area require smooth, the path size of dimensioned to drawing requirement.Screw thread process：Adopt
Processed with screw cutter.The result that thread parameter calculates according to accurate screwed hole hole is adjusted.
Further, half process tool is divided into drill bit, slotting cutter, wherein three kinds of screw cutter, screw cutter shape
PCD is used using 55 ° of -60 ° of chamfer drills and material, ensures the quality stability of product batch production.
Further, the constriction coefficient design and compensation of the half processing thread size, ensure that the precision of thread size.
Further, the semi-finished product process equipment includes common CNC milling machine, lathe or machining center, supporting made
Drill bit, milling cutter, screw cutter, ensure that process ridge occur without collapse it is scarce.
The present invention effect be：（1）Provide a kind of forming method of new carbide alloy screwed hole（2）Various screw threads
Hole, can this method be used to process.Controlled by accurate pressed compact constriction coefficient, internal thread machining is carried out to pressed compact, avoided
The difficulty of processing of alloy screwed hole after sintering, a kind of scheme is provided for the processing of carbide alloy screwed hole.

Embodiment
Embodiments of the invention are described in further detail below in conjunction with brief description of the drawings, but the present embodiment is not used to limit
The system present invention, every similar structure using the present invention and its similar change, all should be included in protection scope of the present invention.
As shown in figure 1, hole processing of the present invention is such to work and implementation, it is characterised in that method and step is such as
Under：
1st, drill：Bottom outlet is bored using small diameter drill bit, because drill bit hole surface is relatively rough, it requires that drill bit drills out
Bottom diameter be less than Design of Screw Thread path.
2nd, reaming：Using straight shank milling cutter, expand the endoporus that drill bit processes, bore area requires smooth, size
It is worked into required path size.
3rd, chamfering：Play a part of to prevent machining gap, size requires alloying depth 1.5-2mm.
4th, screw thread process：Processed using screw cutter.
As shown in figure 1, a kind of forming method of carbide alloy screwed hole, its method are as follows：In the case where suppressing billet state, according to
The constriction coefficient of base is suppressed, off-gauge screwed hole is processed using CNC milling machine, after sintering shrinkage, the screw thread that is needed
Hole.The step of semi-finished product are processed is divided into：Drilling, reaming, chamfering, screw thread process.The step 1 as shown in figure, drill bit is in product surface
Process a hole；The step 2 as shown in figure, the size of needs is processed using slotting cutter device to hole；The step 3 as shown in figure, adopt
With rose reamer in end face chamfering；The step 4 as shown in figure, screw thread is processed using screw cutter, and complete adding for this product
Work.
