Description
Technical field
The present invention relates to Large Shear equipment vital part Shot Peening Technology fields, more particularly to Large Shear equipment
Vital part stress peening process.
Background technology
The key components and parts of Large Shear equipment are all made of throwing pill strengthening device and carry out Shot Blasting at present, first, reaching clear
The effect on surface is managed, stress is eliminated second is that playing, reaches invigoration effect；But it is endless that current Shot Blasting method deposits cleaning
Entirely, strengthen the problems such as of low quality.And the vital part of Large Shear equipment is being clamped and is overturning more difficulty, causes it
Shot-peening efficiency is low.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides cleanings more completely, strengthens the higher large size of quality
Shearing equipment ball blast technique.
The technical solution adopted in the present invention is：Large Shear equipment vital part stress peening process, including walk as follows
Suddenly：
A. Large Shear equipment vital part is fixed on inside compressed air shotblasting machine using four paws or six pawl mechanical arms；
B. 1.5 millimeters of second of shot, the grain size of 1.2 millimeters of the first shot, the grain size of 1 millimeter of grain size is selected simultaneously
The 6th of the third shot, the 4th kind of shot of 1.7 millimeters of grain size, the 5th kind of shot that grain size is 2 millimeters, 2.5 millimeters of grain size
Plant shot, the 7th kind of shot of 3 millimeters of grain size is uniformly mixed and forms mixing pellet；Wherein the first shot, second of shot,
Three kinds of shots, the 4th kind of shot, the 5th kind of shot, the 6th kind of shot, the 7th kind of shot account for mixing pellet total weight respectively
20%,13%,10%,10%,17%,12%,18%；
C. the mixture ball obtained in step B is heated to 48 degree of -66 degree, is then loaded into wheel abrator and carries out reinforcing spray
Ball is first dished out 48 degree of -60 degree mixing pellet by the cylindrical tube blade of wheel abrator in shot-peening with the speed of 65.5m/s,
And after beating 40s to the throwing of Large Shear equipment vital part；Then the spouting velocity of shot-peening is controlled in 70m/s, 78m/s, 82m/
S, 95m/s sprays 20s, 50s, 40s, 90s to Large Shear equipment vital part；Finally the spouting velocity of shot-peening is controlled
92m/s, 88m/s, 84m/s, 80m/s spray 90s, 30s, 20s, 15s, at shot peening strengthening to Large Shear equipment vital part
Reason terminates；
D. using the four paws fixed in step A or six pawl mechanical arms adjustment Large Shear equipment vital part and shot-peening
Position relationship between machine, then repeatedly step C.
Further, before step C starts, the mixture ball obtained in step B must be heated to 55 degree of -62 degree, then
It is loaded into wheel abrator and carries out reinforced peening.
Further, after step C is repeated 3 times, compressed air shotblasting machine need to be opened, the part of Large Shear equipment is observed, such as
Fruit visually observes surface quality and meets the requirements, and also needs to carry out Surface testing using tool, requires if being unsatisfactory for strengthening, returns again
Operating procedure C is returned, but needs to manually adjust the part shot-peening angle of Large Shear equipment.
Further, either six pawl mechanical arms drive it to rotate or overturn to the four paws in step A by hydraulic pressure or air pressure
Large Shear equipment.
Compared with prior art, the beneficial effects of the invention are as follows：The Large Shear equipment intensification technique of the present invention, makes first
Large Shear equipment vital part is fixed on inside compressed air shotblasting machine with four paws or six pawl mechanical arms, can be turned in time in shot-peening
Turn Large Shear equipment, ensures that each surface of Large Shear equipment can be handled uniformly；In addition, the technique of the present invention uses
The wherein shot mixing of different-grain diameter is heated to 48 degree of -66 degree input compressed air shotblasting machine after mixing, then compressed air shotblasting machine is spent at 48 degree -60
When dished out with the speed of 65.5m/s, and to Large Shear equipment vital part throwing beat 40s after；Then by the spouting velocity of shot-peening
Control sprays 20s, 50s, 40s, 90s in 70m/s, 78m/s, 82m/s, 95m/s, to Large Shear equipment vital part；Finally
By the control of the spouting velocity of shot-peening in 92m/s, 88m/s, 84m/s, 80m/s, to Large Shear equipment vital part spraying 90s,
30s, 20s, 15s, shot peening terminate a surface, and the Large Shear equipment surface which obtains is smooth, slightly
Rugosity is lower.
Specific implementation mode
In order to deepen the understanding of the present invention, with reference to embodiment, the present invention is further described, which only uses
In explaining the present invention, protection scope of the present invention is not constituted and is limited.
