2. Die Structure

2.1 die working process

Draw→ hole punching →collar making →edge trim →slitting → wave vertical cutting → feeding → cut-off  

2.2 die structure

2.2.1 drawing die: 6 steps. Height is adjusted through SIKO regulator on the die. Each step can be adjusted separately. The last step can finish the forming of the V-shape wave.

2.2 hole punching: The slide block of the press moves downward to punch the holes and moves further to control the fin height.

2.2.1 The punching sub-die is equipped with the separate columns and sleeves to ensure the forming accuracy and service life. The die can be easily maintained and replaced.

2.2.2 The upper punching die plate is equipped with the sealing device to avoid air leak and ensure smooth downfall of the waste material.

2.2.3 The lower punching die is designed with the cushion plate to avoid pit occurrence of the big die plate and ensure the service life of the lower die plate.

2.2.4 The waste material downfall hole of the lower die plate ensures the smooth downfall.

2.2.5 The concentricity of the punching concave and convex die is controlled within 0.002mm which enables easy interchangeability of the parts.

2.2.6 The punching convex die is set with the air hole both horizontally and vertically so as to ensure lubrication and cleaning. At the same time it adopts the automatic oil mist lubrication device to ensure the mandatory waste material removal.

2.2.7 The collar concave die sleeve is provided with a push sleeve to prevent the waste from being stuck in the die sleeve during the drawing process and to force the waste out.

2.2.8 The punching concave die adopts the clamp table structure. An overall fixation plate fixes this die to prevent it from moving upward and avoid die damage.

2.2.9 Collar forming die: collar height is adjusted by SIKO regulator of the die. The collar height of the same row has an accuracy of ≤0.02mm, and that of different rows have an accuracy of ≤0.03mm.

2.3 edge trim mechanism: The edge trim cutting die is an independent structure which cuts off the extra material of the sides. Additionally the cut material is kept from bouncing upward. The upper blade is designed as 2-side blade structure with prolonged service time and improved efficiency.

During edge trimming process, the die also guides the formed Φ9.85mm hole upright so as to avoid fin shifting horizontally. The guide sub-die adopts the rigid (or elastic) strip unloading design with a high accuracy. There is no hole stepping problem. The guide convex die is of easy installation and dismantling type.

2.4 slitting: The upper and lower blade could cut the fins with the wanted rows. The upper cutter blade is of fast replacement type. The upper die plate is marked with numbers 1-11 for 1-11 rows. The operator could easily adjust the rows number easily. The upper and lower blade is replaceable. And the upper and lower blade should have a reasonable gap.   

2.5 wave edge vertical cutting: it could cut the fin with the wave edge.

2.6 feeding: we adopt the best traction type feeding mechanism. There is a tiny catching finger on the die which could draw the strip forward through the formed holes. The catching finger is made of SKD11 material. There is an oil-free lubrication sleeve between the catching finger and the fixation plate to ensure long service life and accurate positioning.  

2.7 Cut-off: The cut-off mechanism cuts the fin at the length wanted through the pneumatic cylinder, the solenoid vale and the electrical control loop.

The cut-off mechanism adopts oil-free lubrication method, and the contact area of the oil-free lubrication is designed as big as possible. The front of the cut-off die is set with a fin curvature regulation mechanism. The cut-off die could move half step distance, and allows position adjustment forth and back. There is no hole cutting or stepping problem during cut-off.  

3. Die Material

3.1 All the guide sleeves of columns, feeding shaft, and edge trim cutter are designed with timed and rated lubrication mechanism. The oil supply connection between the die and the fin press is of easy removal type.   

The drawing upper die and punching upper die are lubricated with the volatile oil mist.

3.2 The waste material from the punching and edge trimming mechanism is removed by the jetting air.  

3.3 The port size of the hydraulic oil, the lubricant, fin oil, and compressed air matches that of the fin press. All the fittings and hoses are imported.  

3.4 The positioning hole size and bolt hole size of the upper and lower die seat matches that of the fin press so that the die is stably and reliably installed together with the press.   

3.5 All the pins and springs of the die are standard ones (Punch brand, Japan). The compressed air pipeline is appropriately designed, and the waste material is easily removed. There is no clogging problem of the waste material.

3.6 The die already includes the position column for the upper die closing.

The machine is packed in plywood cases which can be moved through forklift by its feet.

The nearest sea port is Shanghai port which is the largest and most convenient port over China.

The delivery time is 60 days after receipt of down payment.

The machine can be loaded into normal container (20GP or 40GP).
