Q37 hook type shot blasting machine / hook shot blasting equipment
This machine is for surface cleaning or strengthening treatment of small castings, forgingparts in industry of foundry, building, chemical, motor, machine tool etc. It is special for surface cleaning and blasting strengthening on various types, small production castings, forging parts and steel construction parts for clearing little viscous sand, sand core and oxide skin. It is also suitable for surface cleaning and strengthening on heat treatment parts, especially for cleaning slightness, thin wallparts which is not suitable for impact.
1. Application
Q37 shot blasting machine is a specially designed machine used in the surface cleaning for various small and large jobs. It can realize the shot blasting automatically.
2 Components and function
Q376 shot blasting machine consists of blasting system, blasting chamber, abrasive circulation system (separator, bucket elevator, screw conveyor), chain conveying system, dust collection system and electric control system. The surface finish level is Sa2.5.
2.1 Shot blasting system
Shot blasting system consists of blasting chamber and shot blasting machine assembly. The abrasive media like the steel shots, grits are applied on the metal surface driven by the centrifugal force from the blades. Workpieces will be de-rusted, cleaned and roughened in blasting system to reach customer's finishing level.
2.2 Blasting chamber
In the blasting chamber, the wall is protected by SPMn13 material protection linear, which has high wear resistant performance. Chamber inside protection plate all adopt the high strength nut fixed and pressure on the inner of blasting chamber, easy tear open outfit replacement. Prolong service life, reduce the cost and reduce maintenance frequency. The steel grilling floor of blasting chamber can let abrasive fall through it freely and collected by screw conveyor.
2.3 Shot blasting machine assembly
This machine has 2 sets of high speed & performance blast wheels. One blast wheel has eight blades. It takes 5 to 10 minutes to replace 8 pieces of blades. Material of blades, control cage and distributor is Cr20S high-chromium cast iron (USA: 5115G51150 Model), which has long service life. Generally speaking, lifetime of blade is over 500 hours, and lifetime of impeller and control cage is over 800 hours. All wear parts are the market most universal national standard parts.
2.4 Abrasive circulation system
The system includes following parts: hopper, abrasive flow pipe, abrasive control valves, screw conveyors, bucket elevator, separator.
2.4.1 Screw conveyor
Screw conveyor consists of cycloid needle wheel decelerator, screw axis, conveyor shell, bearing, etc. It is a standard transverse conveying device, an important part of abrasive circulating system. The screwing blade is made of 16Mn.
This unit is responsible for the abrasive delivered to the elevator. Screw conveyor located at the bottom of shot blasting chamber, the spiral blade welding in the drive shaft. Conveyor motor through cycloid speed reducer drive rotary screw conveyor, send abrasive to discharge outlet, then the mixed abrasive will be collected to elevator bottom.
On both ends of the screw conveyor adopts triple seal protection, plus labyrinth seal cover in the interior of the end plate, middle with oil seal protection, end plate external insulate bearing and end plate. Once the abrasive and dust out, will drop from the end plate and bearing clearance, will not enter the bearing. Screw conveyor shaft with sensors detecting means, can detect the working state.

Main Features
This series is hook type shot blasting machine, is mainly used for surface cleaning of casting, structure, non-ferrous and other parts. This series shot blasting machine have many types, such as single hook type, double hook type, lifting type, non-lifting type. It has advantage of non-pit, compact structure, high productivity, etc.
1). The equipment is mainly applied in the processing of medium and small size workpieces in large scale. It has the advantage of high efficiency, compact structure.
2). Workpieces can be transported continuously. The working procedure is that, setting the speed, hanging workpieces over the hooks, and removing them after shot cleaning.
3). Each single hook can hang weight from 10 kgs to 5000 kgs with high productivity and stable running.
4). It makes a best effect on complicated workpieces both the surface and inner part, such as cylinder cap of engine and motor casing.
5). It is an ideal choice for auto, tractor, diesel engine, motor and valve industry.
