1.General Description Of The Machine
The Q2610 flat car type manual shot-peening room is special equipmentdesigned to meet specific process requirements. Through the shot-peening can remove the complex work piece surface contamination, the oxide skin, welding slag, the waste paint and so on, causes the work piece surface to be bright and clean, simultaneously reduce the work piece internal stress, enabls the work piece surface to obtain the strengthening, thus achieves enhances the work piece surface and the intrinsic quality goal.
2. Work environment
2.1 Power supply: AC380V/3p 50HZ
2.2 Compressed air consumption: 6.3m3/min; 0.5-0.7MP
3. Structural characteristice
This machine is a special reciprocating flat car hand shot- peening machine, which consists of shot-peening chamber, shot-peening device, Screw Conveyor, elevator, separator, Shot distributing system, flat car system, flat car guide and support, lighting system, the bottom funnel, grid plate, dust- removing system, electric control system and so on
The shot-peening system is equipped with 1 sets of shot peening device, 2 guns. We fully take into account the operation convenience of the workers, specifically increased the shot-peening chamber operating space, set lighting system and platform, so that workers can operate convenient, effective and comprehensive on piece parts for shot-peening. Lighting system adopt strict protection device, by the organic glass, protective shade and rubber curtains etc., open the rubber curtain when the workers manul shot peening cleaning. Shot device technology from Japan thick subway workers produced with the following characteristics.
¯Using remote-control gun control, can realize automatic control. By the operating workers control the nozzle shot- peening or puffing gas. This can be used puffing gas to remova the surface dust after shot-peening; the other hand, can reduce labor intensity and guarantee operation security
¯Shot-peening powerful and stable. Used to long, continuous operation of high pressure to ensure uniform, high-quality cleaning
¯To obtain better Shot peening effect, we specially equipped with high efficiency nozzle, it is high efficiency, good abrasion resistance, long life, and it is the world's advanced products
¯Combinine electricity control and air control system, make the control more rapid, reliable and easy long-distance control
¯This machine equipped with shot peening special protective mask. Protective mask is made up of air filter, double layer composed of a helmet and protective clothing. Through the air filter (remove steam, oil vapor, iron rust, dust and other unpleasant
odors) of compressed air (air filter accuracy of 0.5um) slowly into the double helmet, allowing operators to get the right temperature, the fresh air and comfortable feeling, together with a broad view mask, greatly improving the working environment, and protect the health of operating workers.
3.2 Screw conveyor
The screws convey or consist of reducer, screw shaft, conveying Housing, rolling bearing with bases, etc. It is a kinds of standard abrasive/sand horizontal conveying device, is an important part of the abrasive recycling system of the blasting machine.
The screw conveyor is a serialized part of our company, with high universality and interchangeability, and stable and reliable performance. The whole screw shaft is machined after welding to guarantee the coaxialness.
3.3 Bucket Elevator
The bucket elevator consists of shaft-mounted speed reducer, upper and lower rolling barrel, transmission rubber belt, bucket elevator, enclosure and tightening device, etc.
The inlet opening of the elevator connects to screw conveyor, outlet opening connects to separator.
The enclosure of the elevator is welded after the bending and shaping, on sides of which there are inspection doors, to maintain and replace the buckets On the sides and front faces of the lower housing there are removable doors installed, to maintain the lower transmission and eliminated the abrasive blockage.
Centrifugal weight type shot discharging. During working, the buckets fixed on the conveying belt scrape the abrasive in the bottom, and then carry it to upper of the elevator, then discharge it depending on the centrifugal force.
The elevator equips with the regression preventing mechanism, to prevent it from reverse rotating when the power supply is accidentally cut off. Double rows of buckets, elevated the productivity, and prevented the belt from straying.
On the lower shaft of the elevator, there is impulse Wheel to detect the working status of the elevator. Once the PLC detects that the shaft is not rotating, it will act immediately and generate a fault alarming, to ensure the safe running of the device.
The elevating capacity has 10% spare. Since the elevator discharge the abrasive depending on the centrifugal force. Every discharging, there always is part of abrasive fall into the elevator, and then the elevating capacity should be correspondingly enlarged.
3.4 Shot /dust separator
This machine adopts advanced Model BE full shutter type separator. The separator is mainly composed of airwash area, barrel sift, conveying screw, abrasive hopper, manual abrasive controlling valve.
This machine is developed by absorbing both George Fischer DISA in Switzerland and Pangborn Company in America, is the most advanced separator in our company.
The separator is the key part of this machine, its dimension of the airwash area directly affects the separating effect. If the separating effect is not ideal, the wear to the blades of the blast wheel will be quickened, and its life will be shortened. Furthermore, the maintenance cost will be increased significantly.
The working philosophy of the separator: the abrasive/sand compound that flows from the elevator will be carried into the barrel sift by the conveying screw. The barrel sift has inner and outer screws. During working, the inner screw transfers the large lump of sand or impurities to the dreg exhausting opening; the outer screw pushes the coarsely sifted abrasive/sand compound, to make it be well distributed along the whole length of the separator, and form a waterfall like shutter. Simultaneously, the dust-removing ventilator draws the air from the wind opening of the separator. Relying on the weight and airwash action, the good abrasive will be separated from the metal oxide scale, shattered abrasive, powder, etc. The large granule material flows out of the abrasive overflow opening, fine abrasive and powder will flow out of the waste opening, and the abrasive will enter abrasive hopper to be re-used. By adjusting the clearance of horizontal and vertical baffle, the thickness and track of the abrasive layer will be bettered, and together with adjusting the adjusting baffle in the sifting area, the good separating effect can be gained.
3.5 Shot distributing system
This machine adopts the patented shot valve produced of our company; it can accumulate a certain time in blast-peening, through the manual control to provide the shot ball to the blast-peening device.
3.6 Flat car system(made by user)
Flat car is made up of frames, driving shaft, passive shaft, reducer, steel mesh etc. To facilitate theball fall, non-slip, flatcar surface are bored and welded steel mesh in the above. Flat car driven by the decelerating mechanism, carrying the workpiece entered the shot-penning chamber. Winding cable with cable reels.
3.7 Dust-removing system
This machine adopts Cartridge or bag type dust collector , is exhausted air produced During working ,after treated by dust collector ,is Exhausted into the upper air, and the height ≥16m.the dedusting efficiency is up to 99.9%, powder density is less than 100mg/m3,much stricter than the national standard (GB16297-1966)
The power of the main ventilator of dust collector is 22 kW. This machine adopts ship ventilator technique, double-layer enclosure, and lined with noise-absorbing material, to lower the noise the material of cartridges of dust collector is Dolnaldson (America) product. With the combination of tiny hole film, at one hand improves the filtering performance, at the other hand contribute to eliminate the dust attaches on the cartridges. The cartridges can be easily replaceable. The life of the cartridges is 1-2 year.
3.8 Electric control system
Q2610 Manual shot-peening room, main circuit adopts 3p AC 380V (±10%) 50Hz, and the control circuit adopts transformer isolated AC220V.
Set shot ball circulatory failure alarm function, if any parts of the system fails, the above components automatically stop running, to prevent the shot ball stuck and burning power device.
The shot-peening chamber inspection door and other inprotent part set interlocks device. If the inspection door of the shot-peening chamber is not closed, shot-peening device and other part cannot run.
The dust collector has back flushing technique
