Description

A kind of impeller head

Technical field:

The utility model relates to a kind of component surface treatment facility, the impeller head of specifically a kind ofly be used to cast, industry such as metallurgy, shipbuilding, machining being handled component surface.

Background technology:

Impeller head is a most important core apparatus in the impeller blasting equipment, and its property relationship is to the production efficiency of whole shot-blast apparatus and the quality of surface of the work processing.At present, the impeller head that uses is by advancing the ball mode both at home and abroad, and be broadly divided into three classes: 1, gravity advances the ball beating type; 2, to advance ball sliding for machinery; 3, the ball formula is advanced in air blast; Wherein, advancing the sliding impeller head of ball with machinery especially uses the most extensive.The shot wheel that machinery advances the sliding impeller head of ball mostly adopts mouse cage type structure, when the ball blast amount hour, all right operate as normal, but when the ball blast amount increases, this structure then can't satisfy its need of work, even stifled ball phenomenon appears when feeding ball easily, and ball blast efficient is reduced greatly, influence the operate as normal of shot-blast apparatus.In addition, this structure when feeding ball, bullet and shot wheel mutual friction mutually, crowded, the consumption of non-effective power is big, the bullet shot wheel that rubs simultaneously, the service life of having reduced shot wheel.

The utility model content:

The utility model provides a kind of impeller head, and it is simple in structure, and is easy to use, and the ball blast amount is big, ball blast efficient height, and long service life has solved problems of the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises case, be located at the defeated ball pipe of case one side, be located at backplate, wheel abrator, orienting cover, shot wheel and power drive mechanism in the case, in the be threaded rotating shaft of a band helical blade of a side of the defeated relatively ball pipe of shot wheel, rotating shaft and the coaxial setting of the power transmission shaft of power drive mechanism, the rotating shaft front end of described band helical blade extend defeated ball pipe and go out ball mouth place.

The principle of the utility model utilization screw feeder, in the be threaded rotating shaft of a band helical blade of a side of the defeated relatively ball pipe of shot wheel, described rotating shaft and the coaxial setting of the power transmission shaft of power drive mechanism, the rotating shaft front end of described band helical blade extends defeated ball pipe and goes out ball mouth place, adopt helical blade to carry bullet, mode and motion state that bullet is fed have been changed, dredged and fed the ball passage, make bullet can successfully enter the prismatic blade section of shot wheel fast, fed away then, eliminate stifled ball phenomenon, increased substantially ball blast amount and ball blast rate; And spiral advances ball and can reduce phase mutual friction, extruding between bullet, reduces the abrasion of bullet to shot wheel, reduces the consumption of non-effective power, prolongs the service life of shot wheel.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the inner sectional structure schematic diagram of case.

Fig. 3 is the structural representation of shot wheel part.

Fig. 4 is that A-A among Fig. 3 is to the sectional structure schematic diagram.

Among the figure, 1, case; 2, backplate; 3, protecting cover; 4, orienting cover; 5, directed window; 6, motor; 7, V belt; 8, power transmission shaft; 9, holder; 10, divide the ball blade; 11, helical blade; 12, rotating shaft; 13, disk; 14, ball blast blade; 15 defeated ball pipes.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Shown in Fig. 1～4, the utility model comprises case 1, be provided with backplate 2 in case 1 inside, backplate 2 tops are provided with the protecting cover 3 of sealing backplate 2 and case 1, be provided with defeated ball pipe 15 in case 1 one sides, the output shaft of motor 6 links to each other with power transmission shaft 8 through V belt 7, power transmission shaft 8 stretches into case 1 inside, its end links to each other with the holder 9 of shot wheel by bolt, along the circumferential direction evenly be provided with several minutes ball blade 10 in holder 9 one sides, in the be threaded rotating shaft 12 of a band helical blade 11 of a side of the defeated relatively ball pipe 15 of shot wheel, rotating shaft 12 and power transmission shaft 8 coaxial settings, rotating shaft 12 front ends of described band helical blade 11 extend fail ball pipe 15 go out ball mouth place.The outside at case 1 intermediate solid drive shaft 8 is connected with several ball blast blades 14 by disk 13, ball blast blade 14 on disk 13 along the circumferential direction distribution with divide ball blade 10 position angles identical, between ball blast blade 14 and branch ball blade 10, be provided with orienting cover 4, orienting cover 4 passes backplate 3 and is connected by trim ring or briquetting and case 1, is provided with directed window 5 in corresponding ball blast blade 14 positions, the side of orienting cover 4.

During use, motor 6 drives power transmission shaft 8 by V belt 7 and rotates, drive simultaneously disk 13 and on ball blast blade 14, shot wheel and on branch ball blade 10 and the rotating shaft 12 of the band helical blade 11 that links to each other with shot wheel with fast coaxial rotation, the bullet of coming in from defeated ball pipe 15 is advanced on the branch ball blade 10 of shot wheel rapidly by the helical blade in the rotating shaft 12 11, move in a circle with a minute ball blade 10, when bullet moves to directed window 5 places of orienting cover 4 sides, by action of centrifugal force, gone out by impelling from directed window 5, enter on the impelling face between the ball blast blade 14, one side is with ball blast blade 14 high speed rotating, one side is done radial motion along ball blast blade 14, when bullet is taken to the impeller head outlet by ball blast blade 14, because action of inertia, bullet flies away from ball blast blade 14 and hits on the component surface pending in shot blast room at a high speed, and its surface is handled.Adjust the position of the directed window 5 of orienting cover 4, can adjust the impelling position of bullet.

The utility model adopts helical blade 11 bullet to be advanced to fast on the branch ball blade 10 of shot wheel, improved the ball blast effect of impeller head greatly, the ball blast amount is advanced the ball impeller head with machinery and is compared raising more than 2 times, the ball blast rate improves more than 50%, and adopt helical blade 11 to carry bullet, and changed mode and motion state that bullet is fed, dredged and fed the ball passage, make bullet can successfully enter the prismatic blade section of shot wheel fast, eliminated stifled ball phenomenon; In addition, spiral advances ball can reduce phase mutual friction, extruding between bullet, reduces the abrasion of bullet to shot wheel, reduces the consumption of non-effective power, prolongs the service life of shot wheel.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
