As Fig. 1~shown in Figure 3, the present invention is a kind of safety-type spring ruggedization shot-blasting machine, mainly is made up of super shot blasting cleaning chamber 12, impeller head 8, workpiece conveying mechanism 13, workpiece rotating mechanism 4, auger conveyor 3, bucket elevator 14, shot sorter 11 and dust pelletizing system.
The top of super shot blasting cleaning chamber 12 is fixed with impeller head 8, be furnished with workpiece rotating mechanism 4 longitudinally in the super shot blasting cleaning chamber 12 from top to bottom, workpiece conveying mechanism 13 and auger conveyor 3, the upper fixed of super shot blasting cleaning chamber 12 has shot sorter 11, the rear of super shot blasting cleaning chamber 12 is fixed with bucket elevator 14, the charging aperture of bucket elevator 14 and discharging opening link to each other with auger conveyor 3 and shot sorter 11 respectively, auger conveyor 3 is transported to the shot behind ball blast in the super shot blasting cleaning chamber 12 bottom of bucket elevator 14, after the shot that bucket elevator 14 transports auger conveyor 3 rises to certain altitude, be sent to shot separator 11 again, pill is carried out sorting.The discharging opening of shot separator 11 links to each other with impeller head 8.
Super shot blasting cleaning chamber 12 is places that workpiece carries out Shot Blasting, and workpiece is accepted the shot bump in super shot blasting cleaning chamber 12, fly ball and be effectively controlled.12 fens main cleaning chambers of super shot blasting cleaning chamber and two concubines are arranged to have two impeller heads, 8 air exercise workpiece on main cleaning chamber top.
Main cleaning chamber is a Welding Structure, is made by the high-quality steel, and all by the high manganese steel sheet protection, to replace traditional high chromium backplate, service life is more than 3 years for inwall.High manganese steel sheet can prevent that the shot of sputter from impacting the shot blast room outer wall, thereby avoids equipment damage.The special laying of wearing plate at impeller head 8 places so that the shot of dishing out is concentrated, also can be played control to splashing of shot.All manganese steel backplates adopt special wear-resisting bolting, are easy to demolition and maintenance.The design of main cleaning chamber one side has an access door, is used for upkeep operation at ordinary times, has safety protection switch, can prevent that maloperation from opening door.
Two concubines are separately positioned on vertical both sides of main cleaning chamber, are provided with a cover shot stream curtain sealing device 7 in each concubine.Concubine is a Welding Structure also, is furnished with access door, has safety protection switch, prevents that maloperation from opening door.In addition, join the soft heavy curtain of many covers system in the concubine, form, be used for further preventing that the shot that splashes from spilling body, the injury staff by the wear-resisting Polyurethane curtain of multiple tracks.
Impeller head 8 is core components of shot-blasting machine, makes the pill of throwing to workpiece obtain higher initial velocity (adjustable-speed), removes surface of the work oxide skin, eliminates the spring surface stress, strengthening surface intensity.
This impeller head 8 is an associated mode, and it is more reasonable to arrange, more compact structure.Motor adopts famous brand name, specific bearing and spindle nose design.Impeller head 8 adopts frequency controls, and frequency converter is installed in the Electric Appliance Cabinet, can be used for adjusting and the rotating speed of stable impeller head 8, realizes the adjustable function of ball blast intensity.The shot initial velocity is only in higher scope, strengthen unlike spring in the past, in order to reach strengthening effect, draw high the ball blast initial velocity simply, after the shot initial velocity is too high, bring a lot of negative effects, the equipment consumable accessory is not durable, and impeller head, equipment body etc. are fragile, make troubles to corrective maintenance and maintenance etc., thereby directly improve economic consumption, cost increases.
Impeller head 8 mainly is made up of parts such as electric motor with vane wheel, blade, shot wheel, orienting cover, impeller head shell and liners.The core component of impeller head is an impeller, has good dynamic balance, and 8 high hardness wear-resisting blades are housed on the impeller, direct plug-in, every cover blade weight difference is controlled in the 3g, noise and vibration when greatly reducing the equipment operation, and the service life of prolongation consumable accessory.Also have an orienting cover and a shot wheel in addition, play the effect of control shot impelling direction and preaceleration shot respectively.The ramming head inwall is with abrasion-proof backing block, and it is convenient to change, and abrasion-proof backing block is a special facture, and the flow direction of shot is play the guiding role, and can prevent effectively that shot from splashing.
As Fig. 4, shown in Figure 5, be the workpiece rotating mechanism 4 among the present invention, 4 pairs of workpiece of workpiece rotating mechanism are rotated, so that workpiece is accepted even ball blast, guarantee the minimum coverage rate of workpiece.Workpiece rotating mechanism 4 is installed in the super shot blasting cleaning chamber 12 of spring shot-blasting machine, be positioned at the top of workpiece conveying mechanism 13, it comprises the roller 22 of the rotatable two same sizes that be arranged in parallel, two rollers 22 are installed on the sidewall of super shot blasting cleaning chamber 12 by clutch shaft bearing seat 16 respectively through whole super shot blasting cleaning chamber 12.
The same end of two rollers 22 is separately installed with a driven sprocket 17, two driven sprockets 17 link to each other with the drive sprocket 19 that is installed in first reducing motor, 20 axle heads by first roller chain 18, first reducing motor 20 is installed on first motor cabinet 21, and first motor cabinet 21 is installed on the sidewall of super shot blasting cleaning chamber 12.
