Coil Spring shot peening machine is a kind of equipment for spring surface treatment. Shot blasting strengthening is a specially designed technology to improve the fatigue strength of components subjected to alternating stress. Cyclic plastic strain layer is produced on the surface of spring by the impact of high-speed steel shot flow on the spring surface, which leads to favorable changes in the microstructures of the spring surface and the introduction of residual compressive stress field into the surface. Thus, the fatigue fracture and stress corrosion fracture resistance of the spring can be improved, and the reliability and durability of the spring can be improved.

Brief Profile

Mayflay offers specially-designed coil spring shot blasting machine for constant and continuous blasting of de-scaling, de-sanding, cleaning and pre-treatment for different types of spring with great processing capacity.
It is a strengthening technique to enhance springs’ anti-pressure performance and fatigue strength. High-speed shots from the blasting wheel hit on the surface of springs to generate cyclic plasticity strained layer, leading to advantageous changes of microscopic structure of spring surface, and having high resistance to fatigue break and stress corrosion, which guarantees springs’ reliability and durability.
It features in continuous processing, no crush among work pieces, great blasting capacity, high efficiency, guaranteed sealing system and compact design for easy loading and unloading.

Application


Mayflay coil spring shot blasting machine is highly flexible systems that can be applied all kinds of spring in the fields of automotive, railway, vehicle etc.

Dedication & profession


Dedication & It is a strengthening technique to enhance springs’ anti-pressure performance and fatigue strength. High-speed shots from the blasting wheel hit on the surface of springs to generate cyclic plasticity strained layer, leading to advantageous changes of microscopic structure of spring surface, and having high resistance to fatigue break and stress corrosion, which guarantees springs’ reliability and durability.


High-end blast wheel & accurate blasting

Fully CNC machined blast wheels provide accurate and effective blasting result for different work pieces with extremely long lifespan. And 37KW working power guarantees satisfactory and high-efficiency shot blasting result.


Reliable quality & long lifespan


Shot blasting chamber is completely engineered of steel plates with thickness between 6 and 10 mm and welded in one piece, making the machines extremely tight and sturdy. For optimum wear protection, the area exposed to the blast stream is lined with replaceable protective manganese steel plates. These overlapping liners are not bolted on but hung with a special system.


Programmable Logic Controller


PLC control unit handles all process parameters of work pieces blasting without unnecessary repeat input, saving much time of parameter configuration, much working hours of operator.
Smart communication with built-in 3D guiding technology UI and 7 Inch colorful touch screen for safe operation, easy maintenance.


Environment protection


Great importance is attached by Mayflay to environment protection: noise and dust emission. We adopt high-end methods to reduce noise to 85DB and dust emission concentration to less than 50mg/m3 (these results can be even better with higher standard of configurations).

Main Parts

Roll Conveyor System in blasting chamber


The coil spring shot peening machine uses two rolls to make the spring moves forward; the leaf spring shot peening machine uses special jigs to hold the spring.

a. It is composed of chain sprocket, push tooling and drive motor. It can be operated forward and backward by frequency conversion speed regulation. The spacing of dialing tool shaft is 550MM, and the spacing of rollers can be adjusted (the adjustment time is less than 20 minutes).

b. A set of drum rotating system includes two rollers, sleeves, bearing seat and sprocket chains. Driven by decelerating motor, it can operate in both positive and negative directions by using frequency conversion speed regulation.

Blasting chamber system


a.6mm-10mm thickness steel plates well-welded in one piece and a line of thick Mn 13 steel protective boards at exposed area to the blasting shots stream, guarantee excellent wear resistance of the blasting machine. These protective boards are not bolted on but hung with a special way and easy to assemble and replace.
b.A unique special multi-layer sealing system is developed and installed. It combines with brush seals and rubber segments to keep the machine sealing effect excellently when the hooks and cross bar are adapted to the sealing system and it prevents accidents of shot spillage.

Screw conveyor system


a.2 or more screw conveyor systems are installed at the bottom of the blasting chamber and driven by the gear motor of the bucket elevator. During working, the screw conveyor transits the shots to the bottom of the bucket elevator and the shots are lifted by the buckets to the upper part of the elevator and put into the shot separator.
b.1 screw conveyor system is installed at the top side of the bucket elevator to both push shots to the shots separator and separating partial dust and small broken shots through the roller filter.


Bucket elevator system


a.The dismountable elevator is is driven by 1 gear motor at the top of the elevator and built with steel plates by accurate soldering technique and It includes 2pcs high-quality wheel hubs, 1 elevator body, 1 high-performance and durable belt and several alloy buckets.
b.The maximum transfer amount of the elevator is 120Ton/H. It collects and lifts the shots recycled by the screw conveyor onto the separator and storage cabinet.

c.An access port is designed on the elevator for easy maintenance and examination.

Separator system


a.The air-flow separator is used to separate good shots and broken shots and dust. It is built and soldered with steel plates and different chambers are designed inside to lead the air flow and multi-level steel plates are installed to adjust and balance the sliding shots flow amount. 

b.The shots & dust mixture goes downward on a sliding steel board and get into the way of

the air flow. Good shots are heavy and not driven to move by the air flow but broken shots are much lighter to be lead to the other slide board that connected with a broken shot collector/bucket. Dust directly flows in the air flow direction and is taken to the air outlet to be dealt with by the dust collector.    

c.Magnetic separator is optional for powerful sand separating of sand-casted parts.


Semi-automatic flow valve


a.Fully sealed semi-automatic flow valves are designed and equipped with lockable examination window and 2 bearings to control the flow amount of the shots into the blast wheels
b.At the upper part of each flow valve, a manual stop valve is installed to stop the shots flow under the circumstance of examination or maintenance.


CNC machined blast wheel system


a.Mayflay fully CNC machined blast wheels have excellent performance of dynamic balance and perfect shots output efficiency and great convenience for maintenance, based on its referred blast wheel model TITAN Series from SCHLICK Corporation and in combination of our own industrial advantages and features. It is combined with a highly hard-wearing impeller, 8pcs extremely hard and durable plug-pull type blades, a control cage and a shot distributor to control the blasting direction and pre-accelerate.
b.Mayflay P series power system is used in this blast wheel: specially-designed and manufactured ABB motor, die steel CNC machined + low-pressure & vacuum heat treatment vulnerable parts inside. These extremely durable vulnerable parts have 58-62HRC surface hardness and super long lifespan.

Dust Collector System


a.It includes cyclone separator and the cartridge filter. The cyclone separator separates most of heavy dust and the cartridge filter blocks and filters the escaped air & dust mixture.
b.Electromagnetic pulse technology is applied in the cartridge filter to shock and separate the dust from the filter. Dust goes down to the collect storage cabinet due to its gravity. Silencer and secondary filter ensure that noise emission is lower than 85DB and dust emission is lower than 50mg/m³
c.Wet dust collector is optional, a high performance dedusting system with Venturi theory, especially for flammable and explosive media, automatically recycle dust.

Electrical control cabinet


a. Adjustable shot peening parameters set from operator’s panel (frequency inverter on throwing wheels, roller’s drive, pushing system).

b. Data exchange with Programma Siemens Brand Touch Screen and PLC.
