Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Below in conjunction with accompanying drawing 1 and Fig. 2, concrete introduction is done to the process steps of Split type coupler structure of the present invention:
A processing method for Split type coupler structure, described Split type coupler comprises main connection, middle adpting flange and from connector, and described processing method comprises the following steps,
The blanking of the first step, main connection, the method of Vehicle Processing formation one is adopted to have the main connection of the first branch sleeve 1 and the first adpting flange 4, main connection is offered the first connecting through hole 6 (boring), and at end opens first groove 9 (Vehicle Processing) of the first adpting flange 4.
The blanking of second step, middle adpting flange 3, adopts the method for boring formation one to have the middle adpting flange 3 of middle connecting through hole 8, offers the second groove 10 and the 3rd groove 11 (Vehicle Processing) at the two ends of middle adpting flange 3 respectively.
3rd step, blanking from connector, adopt the method for Vehicle Processing formed one have the second branch sleeve 2 and the second adpting flange 5 from connector, the second connecting through hole 7 (boring) is being offered from connector, and at the end opens the 4th groove 12 (Vehicle Processing) of described second adpting flange 5.
Main connection and middle adpting flange 3 are welded in one by the first groove 9 and the second groove 10 by the 4th step, employing welding equipment, adopt welding equipment will be welded in one, to form a new coupling product from connector and middle adpting flange 3 by the 3rd groove 11 and the 4th groove 12.
5th step, coupling product is carried out modifier treatment, i.e. the step that combines of Quench and temper.Main connection in shaft coupling of the present invention, middle adpting flange 3 and the 45# steel from the equal employing of connector part, 45# steel is medium carbon structure steel, and cold and hot working performance is all good, better mechanical property, and price is low, source wide.
45# steel hardening heat, in A3+ (30 ~ 50) DEG C, adopts 850-900 DEG C in the present invention, and such hardening heat can make shaft coupling firing rate accelerate, and surface oxidation reduces, and can improve work efficiency.For making the austenite homogenising of workpiece, just need enough temperature retention times.If in actual mechanical process, the batch of coupling product is large, just needs proper extension temperature retention time.Not so, may occur because heating the uneven phenomenon causing hardness deficiency.But temperature retention time is long, also also can there is coarse grains, the disadvantage that oxidation and decarbonization is serious, impact quenching quality.
Because #45 steel hardenability is low, therefore 10% saline solution that cooling velocity should be adopted large.After coupling product enters water, should through hardening, but should be not cold, if coupling product is cold in salt solution, just likely workpiece is ftractureed, this is that austenite changes rapidly martensite into be caused caused by excessive structural stress due to when work-piece cools is to about 180 DEG C.Therefore, when quenching workpiece is as cold as this temperature province soon, the method for slow cooling should just be taked.Because leaving water temperature is difficult to grasp, must operate by rule of thumb, when the workpiece shake in water stops, water-air cooling (if oil cooling is better) can be gone out.In addition, coupling product enters water and should move unsuitable quiet, according to the geometry of workpiece, should make regular motion.Hardness after coupling product quenching should reach HRC56-59, the large possibility in cross section is lower, but can not lower than HRC48, not so, just illustrate that workpiece is quenched completely, may occur sorbite even ferritic structure in tissue, this tissue passes through tempering, still retain in the base, do not reach modified object.For the high tempering after coupling product quenching, its heating-up temperature is generally 560-600 DEG C, and hardness requirement is HRC22-34.
Due to the structure that the present invention adopts main connection, middle adpting flange and is welded to each other from connector, relative to existing casting, have that processing technology is simple, efficiency is high and the advantage that machining accuracy is high.
Consult shown in Fig. 2, the Split type coupler structure of processing required for method of the present invention, comprise main connection, middle adpting flange 3 and from connector; One end of described main connection is provided with the first groove 9, the two ends of described middle adpting flange 3 are respectively equipped with the second groove 10 and the 3rd groove 11, described one end from connector is provided with the 4th groove 12, described main connection and middle adpting flange 3 are by the first groove 9 and the second groove 10 welding fabrication, and described middle adpting flange 3 passes through the 3rd groove 11 and the 4th groove 12 welding fabrication with from connector.
Described main connection comprises the first branch sleeve 1 and the first adpting flange 4 of integral type, and described first groove 9 is located at the outside of the first adpting flange 4, is also provided with the first keyway 13 in described first branch sleeve 1; Described the second branch sleeve 2 and the second adpting flange 5 comprising integral type from connector, described second groove 10 is located at the outside of the second branch sleeve 2, is provided with the second keyway 14 in described second branch sleeve 2.
First connecting through hole 6 of described main connection, the middle connecting through hole 8 of middle adpting flange 3 and equal from the internal diameter of the second connecting through hole 7 of connector.And the appearance and size of the first adpting flange 4, middle adpting flange 3 and the second adpting flange 5 is equal.
Although describe embodiments of the present invention by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present invention, all should within protection scope of the present invention.
