45ton C Type Metal Punch Die,
9.85mm aluminum fin die,
aluminum fin stamp die For Air Conditioner
progressive stamping fin die metal punch die for air conditioner for air conditioner
The progressive fin die is a professional die working together with
high speed fin press machine. It is also called as metal punch die,
or metal stamp die.
This kind of fin die is suitable for household air conditioner, central
air conditioner, automobile air conditioner, industrial heat exchanger,
dehumidifier, industrial radiator, etc.
It is suitable for aluminum foil of different grades and thicknesses,
and can be customized.
The punching die is easy to maintain and use, and the interchangeability
of parts is excellent. All standard parts such as guide post, guide sleeve,
spring and screw are imported products.

2.3 Use high tensile fin lubricant;
2.4 Fin spec
3.Basic Structure of Fin Die
Drawing → pierce drawing → flanging → trimming→ longitudinal cutting → feeding →
linear cross cutting.
3.1 Drawing: 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 phenomenon.
