The machine is designed to shot peening two leaf springs at the same time which seated on the slave frame in parallel, the inbound and outbound roller conveyor system length can be designed at customer demand. The machine is equipped with various accessories like Shot replenisher, Shot classifier and Shot separator for shot peening application. Magna Valve can also be provided for measuring shot flow rate and for controlling velocity of shot VFD drive is provided to Blast wheel unit. The spring are loaded on conveyor and pass into blast chamber for shot blasting / shot peening application. The shot blasted/shot peened springs come out from outlet vestibules. The operation of machine is continuous. The machine is provided with efficient Dust Collection System.
After being heat-treated, the leaf Spring must be descaled, and after the spring have been pre-cleaned and small slags inclusions have been removed by grinding, the surface is ready for shot peening process. The machine is equipped with Blast Cabinet having inlet and outlet vestibules, The inlet and outlet vestibules are equipped with wear-ressistant rubber curtains that prevent the escape of blast media, 4 high performance turbines deliveried the precision hardning result.
Shot Blasting Effect
Blast cabinet
★Welded by steel plates and profile steel, have enough strength and rigidity.★ZGMn13 steel guard plate, which is hard enough to deal with the shot blasting from 35HRC to more than 55HRC.
★High impact toughness can make full use of the reflection kinetic energy of shot to continue to blast cleaning the surface of work piece, so greatly enhance the cleaning efficiency and quality.
★High chrome wear resistant cast iron grate guard plate which protect the screw conveyor and prevent big clump to get into the hopper damaging the bottom screw conveyor
Blast turbines
★Cantilever centrifugal high efficiency blast wheel, can operate clockwise or counter-clockwise, optimum abrasive flow rate for faster cleaning.★impeller adopted #40 Chrome wear resistant cast iron.
★High chrome wear resistant cast iron for blades, control cage, abrasive distributor.
★Dynamic and static balance.
★Blades of impeller weight tolerance≤±1.5g.
★Unbalanced torque tolerance≤±7.5Nmm.
★Direct drive blast wheel with special motor bearings means less spare parts, less noise, energy-efficient, large abrasive flow rate and good cleaning effect ,etc. advantages.
★Machined housing ensures proper alignment of all internal parts.
★Less part wear due to greater concentricity and more precise alignment.
★Safety interlock is fitted on the housing cover to protect the workers safety.
★Particular guard liner structure increase the abrasion resistant lifespan 60% to 200%.
Pneumatic Abrasive dosing units
★Patented pneumatic control abrasive gate valve, which depend on cylinder to control stroke so as to control the blast wheel in long-distance. This avoids motor burned, blast wheel jammed, shot idling blast and people injured caused by common abrasive control valve closure lax★Abrasive flow is indicated at the ammeter at the electrical switch and control box.
★Adjusting the bolt on the abrasive control valve can conveniently adjust the abrasive flow rate to an required amount
★In order to be able to dismount the abrasive control unit from the silo for repair works and to avoid any abrasive outflow for each unit one manual slide is installed in front of the abrasive control unit.
Abrasive cleaner
Our patented abrasive cleaner is applied for recycling shot/grit, which is to ensures high quality blasted surface and munimal abrasive shot. As the abrasive is so durable it is able to be recycled hundreds of times, resulting in an extremely low abrasive breakdwon rate.Critical to achieving this efficiency is the effectiveness of the abrasive recycling plant. Poorly designed or manufactured abrasive recycling systems will not correctly recycle the abrasive and are unable to maintain the correct abrasive working mix.
Our patented abrasive separator consists of an extended rotary separator drum that will totally remove all big clumps including big wast, scrap and paint chips etc. The abrasive is then fed through a gravity air wash separator where all dust, degraded abrasive and waste is drawn out of hte good abrasive by an air current.
Only good, correctly sized abrasive is fed back to the abrasive storage hopper and blast pots for recycling.
Our patented abrasive cleaner ensures maximum recyling rates of the abrasive and high quality surface finishing is achieved.
