Description
Technical field
The present invention relates to fin processing technique, be specifically related to the processing technique of a kind of flat board leaf-teeth extruding type radiating fin.
Background technology
As shown in Fig. 1 ~ 6, the existing processing technique of flat board leaf-teeth extruding type radiating fin is: (1) cuts: by the size (seeing Fig. 1) that whole piece Al squeezing material severing is single fin, cut open two grooves (seeing Fig. 2)；(2) carpenter 1: carpenter removes leaf-teeth (seeing Fig. 3)；(3) carpenter 2: carpenter removes another side leaf-teeth (seeing Fig. 4)；(4) alkali cleaning: remove product surface greasy dirt and burr；(5) punching press 1(single punch-die): punching, rush salient point, typewriting code (seeing Fig. 5)；(6) punching press 2(single punch-die): chamfering, according to position, hole punch extermal form (seeing Fig. 6).
Above-mentioned processing technique overall throughput is the most lower slightly, multistage manufacturing processes, needs correspondence to put into manpower, equipment, consumptive material etc., relatively costly, and through multistage manufacturing processes, producing bad probability can increase.Its cost is 210 yuan/H/7 people, production capacity: 300PCS/H, and equipment needs 5 lathes.
Summary of the invention
The technical problem to be solved is to provide the processing technique of the flat board leaf-teeth extruding type radiating fin of a kind of simplification.
The technical problem to be solved is achieved by the following technical programs:
A kind of low cost high productivity panel leaf-teeth extruding type radiating fin processing process, by step be:
Step one, sanction are cutd open: by the direction consistent with this whole piece Al squeezing material width, whole piece Al squeezing material is cutd open disleaf tooth at regular intervals and obtains groove, make the leaf-teeth length of a length of final flat board leaf-teeth extruding type radiating fin product of leaf-teeth between adjacent two grooves, and groove width equals to or more than the leaf-teeth edge of the final flat board leaf-teeth extruding type radiating fin product longest distance far from edge, fin floor length direction and beeline sum；
Step 2, alkali cleaning: remove product surface greasy dirt and burr；
Step 3, the progressive die are stamped into final products.
Further, the progressive die described in step 3 is stamped into concretely comprising the following steps of final products:
Hole, (a) punching location；
B () back side rushes character code；
C () rushes salient point, punching；
(d) back side Hole chamfering；
(e) punch extermal form, thrust, obtain final products.
There is advantages that
Original processing technique (cutting-carpenter's 1-carpenter 2-alkali cleaning-punching press 1-punching press 2) is reduced to sanction and cuts open-alkali cleaning-progressive die punching press by the present invention, greatly simplify processing technique, promotes the stability in the course of processing, reduces manpower, improves overall throughput.By processing technique of the present invention, processing cost is 120 yuan/H/4 people, production capacity 450PCS/H, and equipment needs 2 lathes.

Detailed description of the invention
The present invention will be described in detail with embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in Fig. 7 ~ 8, a kind of low cost high productivity panel leaf-teeth extruding type radiating fin processing process, by step be:
Step one, sanction are cutd open: by the direction consistent with this whole piece Al squeezing material 1 width, whole piece Al squeezing material 1 is cutd open disleaf tooth at regular intervals and obtains groove 2, the leaf-teeth length making length c of leaf-teeth between adjacent two grooves 2 be final flat board leaf-teeth extruding type radiating fin product, and each groove widths etc. are more than longest distance a far from edge, fin floor length direction of the leaf-teeth edge of final flat board leaf-teeth extruding type radiating fin product and beeline b sum, and gained semi-finished product participate in Fig. 7；
Step 2, alkali cleaning: remove product surface greasy dirt and burr；
Step 3, the progressive die are stamped into final products.
Wherein, the progressive die described in step 3 is stamped into concretely comprising the following steps of final products:
Hole, (a) punching location；
B () back side rushes character code；
C () rushes salient point, punching；
(d) back side Hole chamfering；
(e) punch extermal form, thrust, obtain final products (seeing Fig. 8).
Due to the fact that the processing technique of flat board leaf-teeth dosage form fin by existing first severing, twice carpenter cuts open except two side portions leaf-teeth, final products are obtained after twice punching press after alkali cleaning, change into first cuing open except part leaf-teeth by whole piece Al squeezing material by the leaf-teeth length separation of final products, alkali cleaning and the progressive die are stamped into final products, therefore significantly simplify technique, and each groove width is equal to or more than longest distance far from edge, fin floor length direction of the leaf-teeth edge of final flat board leaf-teeth extruding type radiating fin product and beeline sum, owing to this groove lower shoe can be simultaneously used for left and right two abutting fins base plate concave portion (shown in Fig. 8), the most directly whole piece Al squeezing material is cut into the width of final fin product, lot of materials can be saved.After using this technique, processing cost is reduced to 120 yuan/H/4 people, and production capacity brings up to 450PCS/H, and equipment is kept to 2 lathes from 5 lathes.
