According to the broach disclosed by the utility model, the broaching molding of quenching parts inner spline can be realized at one step, the broach has the advantages that the accuracy is high, the efficiency is high, the service life is long, the processing cost is low and the like, and is particularly applicable to on-site use of mass production with a high-precision requirement in parts manufacturing industry of associated industry such as automobiles and the like.
Description
Technical field
The utility model relates to a kind of broaching molding cutter, specifically a kind of carbide alloy internal spline moulding broaching tool.
Background technology
On broaching machine, make cutter once be called the broaching processing technology with regard to the process of finishing processing with tractive force by piece surface, cutter used during broaching is called broaching tool.The automobile particularly transmission type component of car adopts the spline form to connect or transmission mostly, and batch is big, required precision is high, generally all adopts the broaching tool broaching of high-speed steel manufacturing to machine before heat treatment for the processing of part internal spline.But all there is inevitably distortion behind part process case-carbonizing processing and the heat-treatment quenching, because part hardness is about HRC60, thereby lack the reprocessing technique method, the precision of spline is difficult to guarantee, except carrying out manual grinding reduction spline accuracy class to being out of shape little part, guarantee reluctantly to be out of shape bigger part and only to scrap processing outside the assembling.
Summary of the invention
Technical problem to be solved in the utility model be to propose a kind of can be to quenched components consisting internal spline realize once broaching moulding, precision height, carbide alloy internal spline moulding broaching tool that efficient is high.
For solving the problems of the technologies described above, the utility model carbide alloy internal spline moulding broaching tool comprises knife bar, carbide alloy spline broach shell, locating ring, adjustment cover and back handle, described carbide alloy spline broach shell is located at the centre of described knife bar, described locating ring is located between described knife bar and the carbide alloy spline broach shell inboard, described adjustment is sheathed on the described knife bar, the outside of described carbide alloy spline broach shell, and described back handle is positioned at the outside of described adjustment cover and is connected with screw thread with the outboard end of described knife bar.
Above-mentioned carbide alloy internal spline moulding broaching tool, the path tooth and the spline tooth of described carbide alloy spline broach shell are staggered, and spline tooth is with wide formula profile of tooth broaching.
The utility model is owing to adopted above-mentioned technical pattern, broaching tool becomes the integrally assembled type structure by original integral structure, the spline broach shell adopts the Hardmetal materials manufacturing, thereby the processing of the shaping after can realizing part internal spline heat on the broaching tool, and the internal spline precision can reach more than 5 grades, the broaching working (machining) efficiency is high, reduced heat treatment scrappage and heat treatment cost widely, realized high accuracy, the one-shot forming of the large batch of quenched components consisting internal spline new process for processing of broaching at a high speed.Except adopting broaching at a high speed, broaching is used with the monoblock type broaching tool and is as good as.The utility model broaching tool part internal spline of once broaching is promptly molded, is to a harden quantum jump of workpiece technological method for processing of tradition, and being specially adapted to related industry parts manufacturing such as automobile has the scene of high-precision requirement, production in enormous quantities to use.It has been broken through the insurmountable conventional art difficult problem of distortion after the part internal spline heat, with existing quenched components consisting internal spline can't shaping processing or manual grinding technology made the one-shot forming processing technology that can broach at a high speed into, by the experiment of broaching in batches, it has following obvious advantage:
1. working (machining) efficiency height: the utility model broaching tool spline cutter hub adopts the alloy material manufacturing, adopts broaching processing at a high speed, and speed＞20 meter per seconds is processed a part, counts the adjustment time in and also has only several seconds, and efficient is more than tens of times of common broaching.
2. part processing precision height: the utility model broaching tool can be processed various complicated profiles of tooth such as the boss that increases on the involute basis, circular arc, chamfering, and the broaching tool spline is designed to side band tooth and rises structure, product precision height.Part internal spline after the broaching tool processing is size and shaped position precision or surface roughness no matter, and quite grinding draws the back internal spline more than 5 class precisions.
3. broaching tool long service life: the spline broach shell adopts the Hardmetal materials manufacturing, and can adopt TiAlN coating to handle, high rigidity, high tenacity, and the durability height can repeat reconditioning and use, and reaches more than ten ten thousand even hundreds of thousands spare service life.In addition, because broaching tool has adopted fabricated construction, knife bar etc. adopt the steel part manufacturing, and are flexible good, can avoid the common phenomenon of forging a knife of whole hard alloy class cutter effectively, also reduced the broaching tool manufacturing cost simultaneously.
4. processing cost is low: the utility model broaching tool is because service life is high, and the cost of sharing on each part almost can be ignored.What is more important has solved the carburizing and quenching problem on deformation of part internal spline, has greatly reduced heat treatment and has scrapped and the heat treatment cost.
Description of drawings
Fig. 1 is the structural representation of the utility model carbide alloy moulding internal spline broaching tool;
Fig. 2 is the A-A cross-sectional view among Fig. 1.
The specific embodiment
As shown in the figure, the utility model carbide alloy internal spline moulding broaching tool comprises knife bar 1, carbide alloy spline broach shell 2, locating ring 3, adjusts cover 4 and back handle 5, except spline broach shell 2 adopts the carbide alloy, remaining part all adopts steel part to manufacture and design, to realize the machining characteristic requirement of broaching tool " the tooth rigid body is gentle ".Knife bar 1 is the parent of broaching tool, and other assemblies are all thereon attached: carbide alloy spline broach shell 2 is located at the centre of knife bar 1, plays shear action during broaching tool work; Locating ring 3 is located between knife bar 1 and carbide alloy spline broach shell 2 inboards, with the circumferential mutual alignment of restriction knife bar 1 and carbide alloy spline broach shell 2; Adjustment cover 4 is located on the knife bar 1, the outside of carbide alloy spline broach shell 2, changes its gauge, can adjust the circumferential position of back handle 5 with respect to knife bar 1; Back handle 5 is positioned at the outside of adjustment cover 4 and is connected with screw thread with the outboard end of knife bar 1.Carbide alloy spline broach shell 2 adopts the path adjective-centre structure, and promptly path tooth and spline tooth are staggered, have guaranteed the axiality of path and spline.Spline tooth is designed to wide formula profile of tooth broaching, and promptly the side transverse tooth thickness increases progressively by tooth, has guaranteed the precision of spline teeth.
