Working Principle

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. According to the modern strength theory of metals, increasing the dislocation density in metals is the main direction to improve the strength of metals. Practice has proved that shot blasting is an effective method to increase the dislocation structure of metals. It is of great significance for some metals that can not be further strengthened by transformation hardening (such as martensite quenching) or on the basis of transformation hardening.

Product Description

1Shot blaster

1. The blasting machine motor adopts ABB with excellent and controllable manufacturing process, good sealing, good dynamic balance and stable and reliable performance advantages.

2. The blasting machine outside shell is made of 10mm high-quality carbon steel plate by laser cutting and precision bending. The shell is welded by special fixture to ensure the parallelism of the two sides of the blasting machine shell and the concentricty of the hole.

3. The top guard plate is precision machined by die steel CNC, and the machining precision is ±0.01. After machining, low pressure vacuum heat treatment is adopted.

4. End guard plate is made of high wear-resistant manganese 13 steel plate by laser cutting.

5. The side guard plate is precision machined by die steel CNC, and the machining precision is ±0.01. After machining, low pressure vacuum heat treatment is adopted.

6. The Orientation sleeve is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

7. The Pill wheel is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.。

8. The blades is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

9. The impeller is precisely machined with CNC die steel, and the machined precision is (+0.01). The surface hardness of the impeller can reach HRC58-62 by vacuum heat treatment under low pressure after machined.

10. The service life of the above vulnerable parts is more than three times as long as that of the casting products (shot material: less than S460 (1.5mm cast steel shot), hardness: HRC40-50).

2Flow valve

1. Semi-automatic flow control system, used to control the flow of shot into the shot blaster, the flow of steel shot is adjusted manually.

2. Fully sealed structure design, with lockable inspection openings and two bearing

3. The upper end of each flow valve is equipped with a manual globe valve. If the flow valve needs to be repaired, it can be closed so that close the steel shot flowing from the silo for easy maintenance.

3Shot blasting room

1. The shot blasting chamber is welded with all manganese steel.

2.Several manganese steel protective plates are installed in the hot zone of shot blasting chamber, which are located in 3/4 of the direct shooting area of the shot blaster. They are fixed by suspension, simple to install and easy to be disassembled and replaced.

3.High strength manganese steel plate and polyurethane sealing curtain are used in the feeding and discharging area to ensure that no steel shot splashes out of the shot blasting chamber.

4. 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.

5. The front end of the internal bearing adopts multi-layer Wen's seal structure to prevent the steel shot splashing from damaging the bearing.

4 Elevator system

1. The elevator is used to lift the steel shots recovered by the screw pusher into the separator and silo.

2.The elevator is made of precisely welded steel plates and can be disassembled in segments. Maintenance and inspection windows are provided for easy maintenance.

3. A drive and deceleration motor is located at the top of the hoist, which acts as the power source of the elevator.

4. The system consists of two precision-machined hubs, one hoist case, one high-performance wear-resistant belt and several alloy hoists formed by one stamping process.

5Roller Chain Conveying System

1. 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).

2. 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.

6Electrical control cabinet

1. Using Siemens PLC and touch screen

2. Using Delta or BEST converters

3. Use CHINT or Schneider brand low-voltage electrical components

4. Using shot blasting time controller

5. Using ADE aerodynamic components

6. Flow detection ammeter

7. 1 lamp

8. 1 set of special constant temperature air conditioning (optional)
