aluminum fin stamp die For Air Conditioner

progressive stamping fin die metal punch die for air conditioner for air conditioner


1. Application

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.

3.Basic Structure of Fin Die

working process:

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.
