Background technology
Parallel-flow heat exchanger is increasingly widely applied as a kind of novel heat exchanger.Parallel-flow heat exchanger wing
Piece is the chief component of parallel-flow heat exchanger.At present, parallel-flow heat exchanger fin, need to be in its table during punching production
Face stamping increases the spacing distance between adjacent, parallel stream heat exchanger fin away from boss, however, being rushed using existing way
Tabletting is away from boss, and not only process is more, low production efficiency, and complete machine production cost is higher, and Forming Quality is poor, and scrappage is high, by
This, is badly in need of solving.
Invention content
It is an object of the invention in view of the above-mentioned problems, providing a kind of pitch of fins boss stamping die of parallel-flow heat exchanger fin
Tool, to solve existing parallel-flow heat exchanger fin
The purpose of the present invention is be achieved through the following technical solutions：
A kind of pitch of fins boss stamping die of parallel-flow heat exchanger fin, including upper mold seat, die holder, the upper mold seat
Lower end is connected with upper padding plate, upper clamp plate, die block in turn, and the upper end of the die holder is connected with lower bolster, lower folder in turn
Plate, convex mould pad, punch retainer, the punch retainer upper edge feedstock direction have been sequentially arranged tearing notch punch-pin, a bending
Punch-pin, secondary bending punch-pin, the die block upper edge feedstock direction be sequentially arranged tearing notch cavity plate, a bending female die,
Secondary bending female die, the protrusion for being molded bending starter bar is provided on a bending punch-pin, and a bending is recessed
It is provided on mould and the matched recess of protrusion.
As a preferred embodiment of the present invention, the upper end of the tearing notch cavity plate is provided with discharging pushing block, and the discharging pushes away
The upper end of block is provided with spring, and the lower end of the spring is resisted against on discharging pushing block, and the upper end is resisted against on upper clamp plate, by setting
Discharging pushing block, spring are put, to improve Forming Quality, avoids damaging during discharging.
As a preferred embodiment of the present invention, positioning is provided on the lower clamp plate, has assisted the initial of feeding effect
Feeding is followed closely.
Beneficial effects of the present invention are that the pitch of fins boss stamping die of the parallel-flow heat exchanger fin passes through tearing notch, one
The punching press of pitch of fins boss is realized in secondary bending, secondary bending three process, has that scrappage is low, product surface Forming Quality consistency
The characteristics of good, and production efficiency height is substantially increased, in addition, bending female die of the male cooperation set on a bending punch-pin
On recess, can stamp out bending starter bar while a bending, both increased the intensity of pitch of fins boss, in turn ensured
The height of pitch of fins boss is identical, simple in structure, be easily achieved.

Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.It is appreciated that
It is that embodiment described herein is used only for explaining the present invention rather than limitation of the invention.
It please refers to shown in Fig. 1 to Fig. 3, Fig. 1 is the knot of the pitch of fins boss stamping die of parallel-flow heat exchanger fin of the present invention
Structure schematic diagram；Fig. 2 is enlarged drawing of the pitch of fins boss stamping die of parallel-flow heat exchanger fin shown in FIG. 1 at A；Fig. 3 is
The structure diagram of pitch of fins boss stamped out using the present invention.
In this present embodiment, the pitch of fins boss stamping die of a kind of parallel-flow heat exchanger fin, including upper mold seat 1, lower die
Seat 2, the lower end of the upper mold seat 1 is connected with upper padding plate 3, upper clamp plate 4, die block 5, the upper end of the die holder 2 in turn
Be connected with lower bolster 6, lower clamp plate 7, convex mould pad 8, punch retainer 9 in turn, the 9 upper edge feedstock direction of punch retainer according to
It is secondary to be disposed with 10, bending punch-pin 11 of tearing notch punch-pin, secondary bending punch-pin 12, the 5 upper edge feedstock direction of die block
