Description

A kind of bead equipment

Technical field

The present invention relates to a kind of bead equipment, more specifically, relate to a kind of bead equipment that can improve the surface of the work cooling effectiveness.

Background technology

Bead equipment is a kind of equipment that utilizes a plurality of steel balls to impact the surface of workpiece and produce residual compressive stress on the surface of workpiece.Like this, if produced residual compressive stress on the surface of the work, then the intensity of workpiece and percentage elongation will increase, and can prevent fatigue crack.

Existing bead equipment comprises the clamping device that is rotatably installed in the box main body, and the pump impeller that is positioned at clamping device one side.According to this device, workpiece is by clamping device clamping and rotation, and a plurality of steel balls are ejected into surface of the work by pump impeller, thereby finishes the processing to surface of the work.

Here, when steel ball impacted surface of the work, the temperature of surface of the work rose, and workpiece may be because heat difference of asking of its surface and inside produce thermal deformation, thereby made the degradation of workpiece.

For anti-problem here, as depicted in figs. 1 and 2, korean patent application No.2002-73827 discloses a kind of bead equipment with cooling unit.

With reference to Fig. 1 and 2, this kind bead equipment comprises main body 15, a pair ofly is rotatably installed in the main body 15 and clamping device respect to one another 10, is positioned at the pump impeller of clamping device 10 1 sides, and a pair of air nozzle 30.Therefore, in the process of bead, above-mentioned bead equipment can be by being reduced the surface temperature of workpiece 5 to the surperficial feed cooling air of workpiece 5 by air nozzle 30.

In addition, as shown in Figure 2, although will cool off the surface that air is fed to workpiece, spray steel ball and can produce air-flow, and the cooling air can be owing to air-flow (shown in the arrow) disperses, therefore cooling off air can not fully contact with surface of the work.And the air that is produced by pump impeller 20 rotation is compared relative warm with the cooling air, and therefore the air that is produced by pump impeller 20 can not make the surface cool of workpiece 5.

Therefore, if use above-mentioned bead equipment, then can not well prevent the thermal deformation of workpiece, thereby can not fully improve the cooling effectiveness of workpiece.

Preferred implementation

Describe preferred implementation of the present invention in detail below in conjunction with accompanying drawing.

Fig. 3 is the view of expression embodiment of the present invention, and Fig. 4 is the view of expression major part of the present invention, and Fig. 5 is the schematic top view of Fig. 3.With reference to accompanying drawing,, the present invention includes box main body 15 as existing bead equipment; Upper and

lower clamping device

12,14, this device is rotatably installed in the main body 15, and can be along rotating shaft closer to each other and rotational workpieces 5; Be positioned at the pump impeller 20 of

clamping device

12,14 one sides; And the steel ball feeder 17 that links to each other with pump impeller 20.And the present invention also comprises first air nozzle 45, and reflector 55 is installed in second air nozzle 60 on the reflector 55, and cooling air feeder 50.Reference numerals 70 expression steel ball cleaners.

First air nozzle 45 links to each other with cooling air feeder 50.First air nozzle 45 is fixed on the downside of top turntable 24 and between pump impeller 20 and workpiece 5.And first air nozzle 45 vertically is installed in the surface of the downside and the close workpiece 5 of top turntable 24.When air feeder 50 was reduced by the cylinder 80 on main body 15 tops, first air nozzle 45 was communicated with cooling air feeder 50, and towards the direction parallel with the rotating shaft of workpiece 5, that is to say towards vertical direction and spray the cooling air.Here, cooling air feeder 50 forms tubular, and the air compressor (not shown) links to each other with cooling air feeder 50 by flexible pipe.

Therefore, as shown in Figure 4, the air-flow that produces when pump impeller 20 ejects when steel ball 1 will promote the cooling air that ejects from first air nozzle 45, and therefore cooling off air can fully contact with the surperficial of workpiece 5.Thereby, can significantly improve the surface cool efficient of workpiece 5.

And

clamping device

12,14 is installed on the disc turntable 22,24.That is to say,

turntable

22,24 form top turntable 24 and lower turntable 22, and

clamping device

12,14 forms the lower fixture 12 that is rotatably installed in lower turntable 22 upsides and rotatable and can be installed in the last clamping device 14 of top turntable 24 downsides with raising.And
