Description
Technical field
The invention belongs to break bar cutter ring working process technical field more particularly to a kind of interference cold pressing treatments of break bar cutter ring
Method.
Background technique
Break bar cutter ring is widely used in the idler wheel of bicycle, in the process of movement to its stability requirement height, and is needed
Keep aesthetics, and in the prior art, mostly abandon the fixed form using external device connection, and use press by the way of into
Row fix, before pressing, to alloy hole go out impurity cleared up using simply clearing away by the way of, cannot completely to impurity into
Row cleaning, during pressing, remaining impurity affects to pressing effect, and before pressing, not right
Alloy nose end is heated, and thermoplasticity is bad, after clearing away impurity, is directly just pressed, is carried out using such mode
Pressing, tightness is bad after pressing, under the action of by extraneous impact force, is easy displacement and unclamps, therefore shock resistance effect is not
It is good, and while pressing, the convex peak of product surface cannot be handled effectively, be pressed together in alloy hole to improve carbide button
Stationarity, and the slickness of product surface is kept, propose a kind of interference cold pressing treatment method of break bar cutter ring.
Summary of the invention
The embodiment of the present invention provides a kind of interference cold pressing treatment method of break bar cutter ring, it is intended to which it is bad to solve stability, table
There is convex peak in face.
The embodiments of the present invention are implemented as follows, and a kind of interference cold pressing treatment method of break bar cutter ring includes the following steps:
S1: production cutter ring annular blank, process are as follows: C, Mn, Cr, Si, Mo, V, Fe, Ni material are proportionally mixed
Melting in the smelting furnace that temperature is 1550 DEG C is poured into afterwards, steel ingot is made, then need to carry out blanking according to cutter ring, with forging die
Cutter ring annular blank is made in method, then cutter ring annular blank is placed in heating furnace, and heating furnace heats cutter ring using ladder-elevating temperature
Annular blank is to 850 DEG C -1000 DEG C, then at furnace inside holding 3.5-4 hours, is then cooled down with the speed of 2 DEG C -4 DEG C/min, when
In-furnace temperature is down to 350 DEG C -500 DEG C, then keeps the temperature 2.5-3 hours, in the speed cooling with 2 DEG C -4 DEG C/min, when cutter ring annular
Slab temperature is reduced to 200 DEG C -275 DEG C and the shifting of cutter ring annular blank is put into atmosphere cooling annealing, is cooled to room temperature state；
S2: rough turn: according to design requirement to cutter ring annular blank clamping centering, the end face and cutting edge of cutter ring being added
Work, and inner hole is opened in the end face of cutter ring, cutter ring inner hole is formed, and guarantee the tolerance and roughness of corresponding size；
S3: drill alloy hole: drilling at cutting edge according to the size of carbide button, forms alloy hole, drills perpendicular to the center of circle；
S4: heat treatment quenching and tempering processing: first quenching cutter ring annular blank, be rapidly cooled after quenching, cooling
Carry out high tempering again afterwards, when high tempering controls humidity less than 50%, and vacuum degree is less than 10pa；Make cutter ring annular after conditioned
Blank has good comprehensive mechanical performance；
S5: cleaning alloy hole: alloy hole in S3 is cleaned using the alcohol of purity 99%；
S6: it is bumped into carbide button: the cutter ring annular blank after cleaning is heated to 200-300 degrees Celsius, directly will after heating
Carbide button is put into alloy hole described in S3；
S7: press compacting:, will treated that cutter ring annular blank is placed on through S6 after carbide button is put into alloy hole
The working end of one-way press greater than 200Mpa, control one-way press work, carbide button is pressed into alloy hole；
S8: finishing inner hole assembles hobboing cutter: using numerical control lathe adjusting tool circle finishing of internal diameter, cutter ring is one of hobboing cutter
Accessory after processing is completed uses the hobboing cutter dress shield machine for being equipped with cutter ring.
Further, the size in alloy hole is set according to demand, and cutter ring hole size precision is 0.02-0.05mm.
Further, S4 high temperature tempering temperature is 470 degrees Celsius -580 degrees Celsius, and hardening heat is 1000 Celsius
- 1120 degrees Celsius of degree.
Further, before being heat-treated in S4, cutter ring inner hole stays 2mm surplus, to prevent cutter ring from deforming.
It further, further include to the independent secondary quenching of break bar inner hole, and to knife after the completion of secondary quenching in the S4
Take turns whole double tempering.
Further, described to break bar inner hole, individually twice quenched hardening heat is 400-450 degrees Celsius, to break bar
The tempering temperature of whole double tempering is 500-600 degrees Celsius.
Compared with prior art, the mistake provided in an embodiment of the present invention for having the beneficial effect that break bar cutter ring proposed by the present invention
Be full of cold pressing treatment method, due to carrying out heat treatment quenching and tempering processing to cutter ring annular blank, so cutter ring annular blank have it is good
Comprehensive mechanical performance；Due to being cleaned using the alcohol of purity 99% to alloy hole, so keeping alloy hole surface clean, have
Effect removes surface impurity；Due to using one-way press, in the state that cutter ring annular blank is in 200-300 degrees Celsius, will close
Golden tooth elastic conjunction is in alloy hole, so tightness is good, since one-way press is pressed in the surface of cutter ring annular blank, knife simultaneously
The microcosmic convex peak of ring shape blank surface is constantly driven plain, and the metal under convex peak not only pushes, but also will be from convex peak two sides
Trench squeezes out, so reducing nao-and micro relief, to obtain small surface roughness；Whole tightness is good, surfacing.
