Abstract
The utility model discloses shot blasting equipment of a spring, comprising an outer diameter blasting gun and an inner diameter blasting gun which extends into a spring eye, wherein the inner diameter blasting gun is connected with a pressure tank so that shot blasting is carried out on the inner diameter of the spring through pressure airflow. Through the shot blasting equipment of the spring in the utility model, the surfaces of the inner and outer diameters of the spring can be evenly strengthened and the anti-fatigue strength of the spring is improved.
Description
[technical field]
The utility model relates to part and strengthens process equipment, refer in particular to the spring shot blasting equipment that is used for the spring bead with and the internal diameter spray gun.
[background technology]
Bead is also claimed shot peening strengthening, is a kind of surface intensified technique that factory extensively adopts, shot peening strengthening; Be at one fully under the state of control, the medium that countless small circular are called shot at a high speed and continuous injection is beaten piece surface; Thereby produce a residual compressive stress layer on the surface, final, part is under the compressive stress layer protection; Improve fatigue resistance dramatically, prolonged the trouble free service life-span.
Be applied to the spring reinforcement process; Bead is ejected into the spring surface with high speed shot stream exactly, makes the spring top layer that plastic deformation take place, and forms certain thickness strengthening layer; Form higher residual stress in the strengthening layer; Because the existence of spring bearing stress can be offset a part of anti-stress when the spring bearing load, thereby improve the fatigue strength of spring.Present spring bead is sprayed in spring external diameter direction all, and like Fig. 1, spring 10 is made spinning motion along a direction; Shot stream 20 sprays spring 10 from shower nozzle 30 ejections by the external diameter direction, makes the spring can be equably by surface peening; But there is certain problem in this mode; The effect that is exactly the spring inside diameter shot-peening is relatively poor, the closeer helical spring of the number of turns particularly, and situation is more obvious.Therefore and since spring inside diameter position shot blasting effect a little less than, often tired source occurs in internal diameter, and causes spring fatigue fracture.
Therefore, providing a kind of spring external diameter and internal diameter same can be necessary by spring shot blasting equipment surface peening, that improve the spring fatigue resistance is real equably.
[summary of the invention]
The purpose of the utility model is to provide a kind of spring shot blasting equipment and the internal diameter spray gun thereof that can evenly strengthen external diameter surface in the spring.
For realizing the utility model purpose, following technical scheme is provided:
The utility model spring shot blasting equipment comprises the external diameter spray gun, and further comprises the internal diameter spray gun that stretches in the spring eye, and this internal diameter spray gun connects pressurized tank, through forced draft spring inside diameter is carried out shot-peening processing.
When spring was carried out shot-peening, spring was made spinning motion, and shot sprays spring by the external diameter spray gun from the external diameter direction, made the spring external diameter can be equably by surface peening; The internal diameter spray gun sprays shot in spring, make the spring inside diameter also can be equably by surface peening.Processing of external diameter shot-peening and the processing of internal diameter shot-peening can be arranged sequencing according to actual conditions, carry out the internal diameter shot-peening and add man-hour, can make spinning motion by control spring, also can control the internal diameter spray gun and do spinning motion.
Preferably, the shower nozzle of this internal diameter spray gun is provided with the spray orifice of a plurality of different directions, all can obtain shot-peening processing except the spring spinning motion can make the internal diameter all directions, and the spray orifice design of a plurality of different directions makes that internal diameter can be equably by surface peening.Preferred, the shower nozzle of this internal diameter spray gun is spherical.On the architecture basics of this technical scheme, spring or internal diameter spray gun can all not done spinning motion, can reach the effect of the even shot-peening of spring inside diameter all directions yet.
Preferably, this internal diameter spray gun is connected with reciprocating movement driving device, can drive this internal diameter spray gun and in spring, move back and forth, and evenly effectively the spring inside diameter each several part is carried out shot-peening processing.As alternative, also can move reciprocatingly by driving spring.
According to the different strengthening effects that will reach, to diameter, the quantity of shot, and the flow velocity during shot-peening all has demands of different.Preferably, this internal diameter spray gun is provided with flow control valve, and this flow control valve is installed in the pressurized tank exit, the quantity of shot in the certain hour section in the time of can controlling shot-peening through this flow control valve.Preferably, on this pressurized tank pressure control device can also be set, the shot flow velocity during with the control shot-peening.
The contrast prior art the utlity model has following advantage:
The utility model spring shot blasting equipment can evenly be strengthened external diameter surface in the spring, has improved the fatigue resistance of spring.
[description of drawings]
Fig. 1 is existing spring shot-blast process sketch map;
Fig. 2 is the utility model internal diameter spray gun work sketch map.
[specific embodiment]
See also Fig. 2; The utility model on the basis of existing technology; Internal diameter direction at spring 3 increases a compensation spray gun; The internal diameter spray gun 1 that stretches in the spring eye just as shown in Figure 2, this internal diameter spray gun connect pressurized tank (figure does not show), through forced draft spring inside diameter are carried out shot-peening processing.When spring 3 was carried out shot-peening, spring 3 was made spinning motion, and shot sprays spring by the external diameter spray gun from the external diameter direction, made the spring external diameter can be equably by surface peening; Internal diameter spray gun 1 sprays shot in spring then, makes the spring inside diameter also can be equably by surface peening.
In the present embodiment; This internal diameter spray gun 1 is connected with reciprocating movement driving device (figure does not show), can drive this internal diameter spray gun and in spring 3, move back and forth, and sprays shot simultaneously; Make fully shot-peening of spring inside diameter, evenly effectively the spring inside diameter each several part is carried out shot-peening processing.
In the present embodiment; The shower nozzle 2 of this internal diameter spray gun is spherical; Which is provided with the spray orifice of a plurality of different directions, all can obtain shot-peening processing except the spring spinning motion can make the internal diameter all directions, the spray orifice design of a plurality of different directions makes that internal diameter can be equably by surface peening.
This internal diameter spray gun also is provided with flow control valve (figure does not show) in the pressurized tank exit, pressure control device (figure does not show) can also be set on this pressurized tank, shot flow velocity and flow during with the control shot-peening.
The above is merely the preferred embodiment of the utility model, and the protection domain of the utility model is not limited thereto, and anyly all belongs within the utility model protection domain based on the equivalent transformation on the utility model technical scheme.
