3.Basic Structure of Fin Die

working process:

Drawing (7 passes) → pierce drawing → flanging → trimming→

longitudinal cutting → feeding → linear cross cutting.

3.1 Drawing: the drawing die is completed by 7 steps. The height

is adjusted by adjusting the regulator on the die, and each drawing

can be adjusted separately to complete V-wave forming in the last

drawing step.

3.2 Piercing and stretching: when the sliding block of the press

machine is lowered, the piercing shall be completed first, the sliding

block shall continue to descend, and then the stretching shall be completed.

3.2.1 The piercing die adopts the structure of independent guide post

and guide sleeve to ensure the forming accuracy and service life, which

is convenient for maintenance and replacement of piercing male and female die.

3.2.2 A sealing device shall be added to the upper formwork of piercing

strethcing die to prevent air leakage and affect waste chip removal.

3.2.3 The base plate that is easy to be replaced shall be added to the

piercing lower die to prevent pits in the large formwork after long-term

production and filling the service life of the formwork under separate protection.

When the female die bursts, the base plate is damaged or the double eye

ring of the fin is unclear, simply replace the base plate.

3.2.4 The material downfall hole of the lower formwork shall not be

chamfered to ensure the smooth discharge of waste materials.

3.2.5 The size and concentricity of piercing male and female die shall

be controlled within 0.002mm, so that the parts have excellent interchangeability.

3.2.6 The piercing male die is provided with air holes in the horizontal and

vertical directions to ensure lubrication and cleaning. At the same time, it

adopts automatic oil supply mist device to ensure forced chip removal.

3.2.7 The piercing and flanging female die sleeve is embedded with a

push sleeve to prevent the waste from being stuck in the flanging sleeve

during stretching mandatory pop-up.

3.2.8 The piercing female die adopts the clamping table structure, and the

integral pressing plate is fixed to prevent it from running up, so as to avoid

damaging the whole die when the female die is blocked and pulled out.

3.3 Flanging: the flanging height can be adjusted arbitrarily through the

regulator on the die.

The flange height difference of fins in the same row is ≤ 0.02mm, and the

flange height difference of any two rows of fins is ≤ 0.03mm

3.4 Trimming : the trimming adopts an independent structure to cut off the

excess edge materials, and has a special method to prevent the waste from

jumping up. The cutting knife is designed into a double-sided knife edge

structure to maximize the service life and efficiency of the knife edge.

3.5 Longitudinal cutting: the upper and lower blades are used to cut any

number of rows of fins. The longitudinal cutting upper blade adopts a fast

switching structure the upper template is designed with 5 rows (1-5) of different

numbers from left to right to realize the rapid adjustment of the number of fin

rows. The upper and lower blades are interchangeable, and ensure that the

gap between the upper and lower blades is reasonable, and there is no

interface edge in the strip.

3.6 Feeding: our feeding form is the best pulling type at present, which is

inserted into the mold through the tiny gripper on the mold pullING the

material in the formed hole forward (using the connecting rod on the die

and press machine). Feeding finger is made of materials SKD11, an

oil-free self-lubricating sleeve is added between the feeding finger and the

fixed plate to avoid inaccurate positioning after long-term pulling movement.

3.7 Straight line cross cutting: the punching in the length direction of the fin

is realized through the cylinder, solenoid valve and electrical control circuit

on the punching machine cut.

The oil-free lubrication method shall be adopted for the transverse cutting part,

and the oil-free lubrication contact surface shall be increased as much as

possible. Each cross cutting front is provided with an independent adjusting

mechanism for adjusting the curvature of the fins. It is more conducive to

the adjustment of the air suction and material receiving system and the

completion of more reliable operation high speed blanking and more flat

fins are produced at the same time, which is conducive to the production

of the next process. Crosscutting can move at half a step distance,

because the cross cutting die is positioned accurately and the front and

rear position adjustment is simple, there will be no cutting hole or touching hole

4.2 Normal working punching speed: 100-250spm (punching according to different flanging

height and single and double jump switching).The pressing speed is adjusted within the

range) (except for the reason of press machine).

4.3 All guide posts, guide sleeves, feeding shafts, edge cutting and other parts of the die

are designed with regular and quantitative lubricating oil supply mechanisms.The oil

supply connection between the tool and the press machine is easy to disassemble.

4.4 Volatile fin oil mist spray is used to lubricate the drawing upper die, piercing upper

die and heat pipe hole upper die.

4.5 The scraps at the piercing and trimming parts shall be forcibly removed by

spraying air.
