Description

Compressed air shotblasting machine

The utility model relates to a kind of machinery of Treatment of Metal Surface, specifically, is a kind of compressed air shotblasting machine of process metal surfaces.

Compressed air shotblasting machine has purposes widely, and as increasing the fatigue life of machine components, the surperficial health of cleaning machine components improves surface of the work paint, zincincation quality etc. and all will carry out bead earlier.Leaf spring with regard to automobile is an example, after bead, can improve 6-10 its fatigue life doubly.Present employed shot-peening machinery has varied, but use the shower nozzle that sprays shot, all be to adopt centrifugal structure, long-term practice proves that there are many drawbacks in centrifugal sprinkler, one can not be controlled shot effectively and flow to, shot is existed everywhere, the shot-peening utilization rate is low, and good situation is about 70%, and 50% of difference does not reach yet, energy waste is serious, and safety in production does not have guarantee; Its two, also produce by force during normal operation and shake; Its three, shower nozzle is many, machine volume is big, the dust suction difficulty.Partly also there are many problems in its anchor clamps, owing to be to adopt many modes that dolly is walked in orbit, cost height, floor space are big, and fault is frequent, energy consumption is high, yield poorly, shot is easily crept at the movable position of wheel and stuck.It is unsatisfactory that existing in a word compressed air shotblasting machine has used many places.

The purpose of this utility model is to provide a kind of directed shot-peening, shot utilization rate height, simple for structure rationally, energy-saving and cost-reducing, operating maintenance is convenient, good dedusting effect and can conveniently handle the compressed air shotblasting machine of freedom and stress state workpiece.

The technical solution of the utility model is: a kind of compressed air shotblasting machine, by shower nozzle 5, anchor clamps 4, shot elevator 1, motor 2, shot reclaims bucket 3, slide ball bucket 6 compositions such as grade, it is characterized in that: the shower nozzle of adorning on the frame is made of shape and structure similar send ball wheel and shot-peening wheel, the terminal pad 9 of its shot-peening wheel is contained on the axle 12 by key 10, the anti-wheel 13 of beating is fixed by connecting bolt 14 and terminal pad 9, primary blades 7 is embedded in and resists in the fluting of beating wheel 13 and chuck 11, the inboard of chuck 11 has the seam device and is resisting on the both ends of the surface of beating wheel 13, connecting bolt 8 is with two connections and primary blades 7 is fixing of chuck 11, leave a determining deviation with the shot-peening wheel, axially parallel is equipped with and send the ball wheel, it send the housing of the outer dress of ball wheel and connects the ball bucket and is fixed on the frame, the ball and go out ball one side opening is all arranged of falling of housing, the ball passage is sent in formation, and it send the front side of vane of ball wheel to be the shovel shape; Be installed on the anchor clamps of shower nozzle below, symmetry is equipped with two blocks of main frame wallboards 23, the inboard symmetry in wallboard upper end is equipped with pop-up track 22, travelling wheel 21 is housed on the track, axle sleeve 20 is housed on the travelling wheel, carrier bar 24 is assemblied on the axle sleeve 20, axle journal place, travelling wheel two ends symmetry is equipped with stress wallboard 27, stress wallboard 1/3 place's symmetry is equipped with self-locking eccentric wheel 26, weight lifting wheel 17 is housed on it, set bolt 15 is housed, clamping workpiece leaf spring 16 between weight lifting wheel and set bolt on it again, in main frame wallboard inboard, symmetry is equipped with stress track 18 and locking eccentric wheel striker 19 between travelling wheel 21 and the weight lifting wheel 17, and main frame wallboard lower end and upper end antimere are equipped with subiculum track 25, and all the other running parts are partly the same with the upper end, sprocket wheel 28 is equipped with at the carrier bar two ends, and its stress track 18 two ends are slopes.

The utlity model has following characteristics:

1, the flow direction of shot has been controlled in strictness, has overcome the phenomenon that the shot of centrifugal sprinkler is existed everywhere, and the shot utilization rate is more than 98%;

2, simplified mechanism, existing shower nozzle can replace a plurality of efficient of centrifugal sprinkler, has cut the cantilever design of centrifugal sprinkler, has overcome by force and has shaken, stable working;

3, improved product quality,, improved the processing workpiece quality because directed shot-peening sprays accurately evenly;

4, improve output, shower nozzle can be widened according to customer requirements, improves the coverage rate of handling workpiece, thereby improves output;

5, solved the dust suction problem effectively, because shower nozzle quantity reduces, machine volume dwindles, and dust suction easily solves, and shot easily reclaims;

6, safety in production is secure, now send ball wheel and shot-peening wheel to fight separately, and has only shot to play instrumentality, has screen pack to check on, and foreign material are difficult to sneak into shot and destroy the shower nozzle parts;

7, saved the energy effectively.Shower nozzle quantity reduces, and recovering mechanism saves, and has reduced energy consumption naturally;

8, chain-type anchor clamps, cost is low, floor space is little, multiple functional, can handle free state and prestressed leaf spring;

9, easy to maintenance, expense is low.Outside the blade of shower nozzle, the easily worn parts such as chain of anchor clamps all are exposed to, change easily.

Fig. 4 is the utility model anchor clamps viewgraph of cross-section.

The utility model is described in further detail below in conjunction with accompanying drawing.

1 is the shot elevator among the figure, the 2nd, and motor, the 3rd, shot reclaims bucket, the 4th, anchor clamps part, the 5th, shower nozzle part, the 6th, slide ball bucket, the 7th, primary blades, the 8th, connecting bolt, the 9th, terminal pad, the 10th, key, the 11st, chuck, the 12nd, axle, the 13rd, anti-wheel, the 14th, connecting bolt, the 15th, the set bolt beaten, the 16th, leaf spring, the 17th, weight lifting wheel, the 18th, stress track, the 19th, locking eccentric wheel striker, the 20th, axle sleeve, the 21st, travelling wheel, the 22nd, pop-up track, the 23rd, main frame wallboard, the 24th, carrier bar, the 25th, subiculum track, the 26th, self-locking eccentric wheel, the 27th, stress wallboard, the 28th, sprocket wheel, the 29th, shot.Shot enters to slip by elevator and struggles against, and enters then to send the ball wheel, and by sending the ball wheel to be sent to the shot-peening wheel, the shot-peening wheel sprays to workpiece; Each joint square of anchor clamps is equipped with travelling wheel, the same travelling wheel of installing of weight lifting wheel, and chain travelling wheel and weight lifting wheel is capable up and down at the stress track simultaneously like this, thereby realizes that chain keeps strong in operation process.Because stress track two is the slope, when chain load leaf spring during, ascents and descents when weight lifting takes turns to towards a direction motion, so just realize the folder of leaf spring straight with reduce.For alleviating mechanical load, maintain static after the each folder of leaf spring is straight, active force breaks away from the stress track fully, wallboard is installed the locking eccentric wheel, after leaf spring weight lifting wheel is gone to the dead point on the slope, the striker that is installed on the stress track has been hit the locked weight lifting wheel of eccentric wheel axle journal in time, works with wallboard by eccentric wheel and pins the downslide of weight lifting wheel; Otherwise during descending, striker also in time rushes open eccentric wheel, and leaf spring is restored.
