Description
Technical field
The present invention relates to pivoting support processing and manufacturing field, particularly relate to the dimension chain control of a kind of pivoting support
System and surface powder injection process.
Background technology
Pivoting support industry has gone through the development in more than 30 years in China, issues first from 1984
JB2300-84 " pivoting support form, basic parameter and technology require " standard, and at 1999 annual overhauls
JB/T2300-1999 " pivoting support " standard ordered, existing China has been to have possessed perfect pivoting support to set
Meter, the comprehensive exploitation ability manufacturing and testing.The most different industries proposes oneself to pivoting support page
Standard, such as wind-power electricity generation, building machinery, bearing industry etc., it can be seen that product progresses into refinement, product
Plant many competition situation.
At present, what on market, consumption was maximum is the supporting of single four-point contact ball slewing, and raceway diameter exists
The overwhelming majority therein is accounted between Φ 500～Φ 1500mm；Nowadays, along with engineering machinery, special purpose vehicle
With the development of industrial robot etc., particularly wind power industry fast growth, quality, the innovation to product
Property is had higher requirement.But high accuracy, the high-end pivoting support market that life-span length, weatherability are strong depend on
So held by the most traditional enterprise, the most domestic be required for import this type of pivoting support a large amount of, domestic enterprise
All face the severe challenge of technological innovation.
Traditional pivoting support adds and directly meets tolerance fit requirement man-hour, and original pivoting support cannot meet
The long-term requirement worked in the presence of a harsh environment, it is impossible to reach corrosion-resistant, wear-resisting and shock proof requirement, existing mesh
Before also have the method for some enterprise's paintings corrosion-resistant, but paint shock resistance is bad, paint is subject to
Can peel off from body with flakey after some impact, lose corrosion resistant effect, and in uneven thickness when spraying paint
The requirement of dimension chain and assembling can not be met.
Summary of the invention
The present invention is to solve that above-mentioned pivoting support is corrosion-resistant, problem that shock resistance and dimension chain control, it is provided that
, the dimension chain of a kind of pivoting support controls, comprises the following steps:
(1) feeding, raw material cuts into blank；
(2) roughing, removes and casts on blank, the irregular epidermis of forging, according to part requirements letter
Singly it is worked into allowance at 3～8 millimeters；
(3) polish, leaves the thickness surplus of dusting of a during polish；
(4) QPQ Quench-Polish-Quench technology, metal material under the operating temperature of 570 ± 10 DEG C with salt bath
Liquid reacts, and can form the compound of one layer of colory densification in metal surface
Layer；
(5) powder injection process, surface dusts, and thickness reaches the length of a, reach corrosion-resistant, wear-resisting,
Shock proof effect；
(6) full-size chain, reaches the requirement of overall size；
Wherein powder injection process step includes:
(1) defat, under conditions of 50-60 DEG C, uses degreasing agent that workpiece is carried out ungrease treatment；Will
Degreasing agent water is diluted, and its solution concentration is 30～40ml/l, sprays product
Ungrease treatment, spray time is 3～4 minutes, removes the oils and fats of surface of the work；
(2) cleaning, use tap water to clean, scavenging period is 1～3 minute, removes the clear of surface
Lotion residual and impurity；
(3) phosphatization, uses Phosphating Solution to soak workpiece, and soak time is 2～5 minutes,
The water-fast crystal type phosphate transfection of surface formation of deposits one layer changes film into；
(4) cleaning, use tap water to clean, scavenging period is 1～3 minute, removes excess surface
Phosphating Solution；
(5) passivation, uses passivating solution to soak workpiece, and soak time is 2～5 minutes, table
Face forms passivating film；
(6) electrostatic powder spraying, use electrostatic spraying mode by need spraying, meet technique want
The powder asked is sprayed on the surface of the product equably by spray gun；
(7) solidification, spray coated after workpiece is transferred in the bakery that temperature is 190～215 DEG C, make
The powder on surface dissolves, levelling and solidification, solidifies 10～20 minutes；
(8) cooling, at normal temperatures cooling 20～30 minutes；
Described phosphatization is that low temperature phosphor operating temperature is at 30～50 DEG C；
Described passivating solution is HNO3+ HF solution, HNO3Should control between 20%～50%, HNO3Concentration be 0～
50%.
The invention has the beneficial effects as follows: the present invention can utilize powder injection process to reach the most corrosion-resistant, resistance to
Impact and wear-resisting effect, when being impacted, the layer that dusts only can deform will not peeling off phenomenon,
Etch-proof ability will not be lost, can effectively extend the service life of pivoting support, and according to the control of dimension chain
System, it is possible to meet the requirement of dimension chain and cooperation, reaches the optimum efficiency of assembling, carries the reliable of pivoting support
Property, it is easy to promote the use of.
