Description
Technical field
The utility model relates to a kind of thread part shot-peenings to cover protective case.
Background technique
Shot peening strengthening is so that surface layer is generated plastic deformation the impact of metal surface using the bullet stream of high-speed motion, by
This causes the metallization structure on surface layer that advantageous variation occurs and surface layer is made to introduce residual compressive stress field, to improve metal
The ability of the antifatigue and stress corrosion resistant of part.Shot peening strengthening is as a kind of fatigue strength for improving metal parts, improvement work
The processing technology of part surface mechanical performance, has there is the history of decades.In the actual production process, the spiral shell of bolt class part
Line part is usually to forbid shot-peening, it is therefore desirable to carry out masking protection to threaded portion, if guard method is improper, be easy to make
At the phenomenon of threaded portion and the Limit Control inaccuracy in the region for needing shot-peening, there is over range shot-peening and part is caused to be done over again
Or the problems such as scrapping.
When shot-peening is processed, due to bullet stream high-speed motion, the power for impacting part metal surface is larger, does not need the area of shot-peening
Domain (non-shot-peening area) equally will receive the shock of bullet stream, therefore the boundary deviation in shot-peening Qu Yufei shot-peening area is needed to need stringent control
It makes (the 6.2nd article that is detailed in HB/Z 26-2011 " aviation part stress peening process "), the safeguard measure in non-shot-peening area is necessary can
It leans on, can just prevent the phenomenon that non-shot-peening is by weak shot-peening (receiving more low intensive shot-peening) and over range (or drain spray ball).
The non-shot-peening area of bolt is protected by the way of adhesive tape at present, this protected mode needs the screw thread in bolt
Position winds multilayer tape, since tape edge is flash, is difficult that the boundary in non-shot-peening area is accurately positioned, be easy to cause boundary inclined
Difference is overproof；In addition, adhesive tape is easy to fall off under the impact of bullet, it also be easy to cause being sprayed for edge breakage and then non-shot-peening area
The phenomenon that ball.The method for protecting thread poor reliability of adhesive tape and not reproducible use at present, have seriously affected processing efficiency and production
Quality.
Utility model content
The purpose of this utility model are as follows: propose one kind can quick-clamping and can to bolt class part threaded portion into
The device of row masking protection, prevents the threaded portion in non-shot-peening area by shot peening strengthening, improves processing efficiency, reduce processing cost,
Improve product quality.
The technical solution of the utility model are as follows:
A kind of thread part shot-peening masking protective case, the masking protective case material are hard nylon；
One end of the masking protective case is provided with internal thread hole, and the internal thread hole is used to protect the screw thread of thread part；
And it is provided with location hole on the side wall of internal thread hole, positioning pin is provided in the location hole, positioning pin is used for will
Thread part is located in masking protective case.
A kind of thread part shot-peening masking protective case, the masking protective case material are hard nylon；
One end of the masking protective case is provided with ladder internal thread hole, and the ladder internal thread hole is for protecting thread part
Screw thread, and the screw thread of every section of ladder corresponds to a kind of thread size of specification；
And it is provided with location hole on the side wall of every section of ladder of stepped hole, it is provided with positioning pin in the location hole, positions
Pin is for thread part to be located in masking protective case.
A kind of thread part shot-peening masking protective case, the masking protective case material are hard nylon；
The left and right ends of the masking protective case are provided with internal thread hole, and the internal thread hole is used to protect the spiral shell of thread part
Line；
And it is provided with location hole on the side wall of internal thread hole, positioning pin is provided in the location hole, positioning pin is used for
Thread part is located in masking protective case.
A kind of thread part shot-peening masking protective case, the masking protective case material are hard nylon；
The left and right ends of the masking protective case are provided with ladder internal thread hole, and the ladder internal thread hole is for protecting screw thread
The screw thread of part, and the screw thread of every section of ladder corresponds to a kind of thread size of specification；
And it is provided with location hole on the side wall of every section of ladder of stepped hole, and it is provided with positioning pin in the location hole, it is fixed
Position pin is for thread part to be located in masking protective case.
Further, the trade mark of the hard nylon is PA1010.
Further, it radially extends to form fixing seat on the outer wall of the masking protective case, the fixing seat and stationary fixture
It is adapted.
The utility model has the beneficial effects that can quick-clamping positioning, after clamped one time can two pieces processing, realize bolt
Accurate positioning and long threaded portion direction accurate protection, the boundary for effectively controlling non-shot-peening area (threaded portion) is inclined
Difference eliminates doing over again and mend blasting process to conventional adhesive tape guard method, improves processing efficiency, reduce and be processed into
This.On the other hand, the sleeve of the device and adjust screw manufactured with hard nylon, can prevent with when feature contacts to bolt
Spiral shell mosquito generates damage, and the paste for also avoiding the piece surface of conventional adhesive tape guard method is difficult to the phenomenon that clearing up.Test proof,
Processing efficiency improves 5 times or more, and product qualification rate improves 20%.
In addition, the bolt class part for needing shot-peening to process is high strength steel metal material, and must be using cast steel ball
Blasting media, the steel ball stream of high-speed motion can make by spray piece surface accumulation the successive shock of metal surface when shot-peening
Heat, if the guard method manufactured using metal material, the heat of protective device can be continuously increased and then injure by spray part,
Therefore part can also preferably be protected using the hard nylon protecting tool set-up for not transmitting heat.
