Description

The hobboing cutter assembly of air-conditioner fin rolling cut submodule
Technical field
The present invention relates to mould, especially, relate to a kind of hobboing cutter assembly of air-conditioner fin rolling cut submodule.
Background technology
Referring to Fig. 1, is air-conditioner fin structural representation of the prior art.Folded the dropping on of several pieces air-conditioner fins 1 is combined into one through poling, tube together, and composition evaporimeter and condenser are the important component parts of heat exchanger of air condition.
Air-conditioner fin 1 is shaping by Mould Machining, and fin die belongs to a kind of continuous stamping die, and aluminium strip copper strips stainless steel etc. is struck out the precision die of various shape, the product produced is used for refrigeration radiating industry.Fin die comprises air-conditioner fin die, high flange fin die, refrigerator fin die, specific use fin die etc.Air-conditioner fin die is applicable to domestic air conditioning, central air-conditioning, dehumidifier etc., and main punching material is aluminium foil.Refer to Fig. 3, for existing air-conditioner fin die structure, it mainly comprises cope match-plate pattern 2 and lower bolster 3, between cope match-plate pattern 2 and lower bolster 3, be provided with stretching submodule 10, piercing die 11, submodule of windowing 12, flanging sub-die 13, abnormity cuts submodule 14, submodule 15 is cut on limit, correcting submodule 16, slit sub-die 17, draw material for making clothes mould 18, transverse cutting sub-die 19, difference also can increase ironing submodule, shutter submodule etc. by mould structure and product flap-type.
Refer to Fig. 2, the air-conditioner fin that air-conditioner fin 1(monoblock does not also cut) in fin die, itemize has been cut along the dotted line 20 shown in figure by slit sub-die 17.Refer to Fig. 4, the longitudinal knife stamping-out itemize of slit sub-die 17, working method is as follows: the every stamping-out of mould once, material advances to discharging direction a stepping length, cut once by the top slitter 171 of longitudinal knife with cutter 172 under rip cutting, in order to guarantee to cut completely, length is cut in general rip cutting can be greater than stepping length, just has the phenomenon producing cutting edge Repeated Cutting in process.
Because the installation accuracy problem of upper and lower longitudinal knife and mould air-conditioner fin between the dynamic departure date can have the phenomenon that swings by a small margin in a mold, Repeated Cutting will produce heavy Qie Maoci, and fraction defective is high.And, after air-conditioner fin production and assembly, do not allow this burr, just need the operation of increase by one deburring.Increase manpower and materials, efficiency reduces, corresponding increase cost.
Summary of the invention
The object of the invention is the hobboing cutter assembly providing a kind of air-conditioner fin rolling cut submodule, and to solve in prior art, air-conditioner fin adds trade union and produces heavy Qie Maoci, and fraction defective is high, but also needs the operation increasing deburring, the problem that cost-effective rate is low.
For achieving the above object, the invention provides a kind of hobboing cutter assembly of air-conditioner fin rolling cut submodule, described hobboing cutter assembly comprises the upper hobboing cutter assembly and lower hobboing cutter assembly that mutually roll and coordinate; Described upper hobboing cutter assembly comprises upper slitter fixed cover, is provided with upper bearing (metal), arranges fixed axis in described upper bearing (metal) in described upper slitter fixed cover, and the both sides of described upper slitter fixed cover are fixed with cutter respectively; Described lower hobboing cutter assembly comprises lower cutter fixed cover, is provided with lower bearing, arranges lower fixed axis in described lower bearing in described lower cutter fixed cover, and the both sides of described lower cutter fixed cover are fixed with bottom knife respectively; The cutting edge of described cutter and the cutting edge of described bottom knife are mounted opposite.
Further, the outside of described upper slitter fixed cover and described lower cutter fixed cover is respectively arranged with adjustment pad.
Further, the both sides of described upper bearing (metal) and lower bearing are respectively arranged with sealing shroud.
Further, between described upper hobboing cutter assembly and described lower hobboing cutter assembly, two pieces of stock guides are installed.
The present invention has following beneficial effect:
Hobboing cutter assembly substitutes traditional longitudinal knife, rolling cuts, make air-conditioner fin itemize without Repeated Cutting part, impulse-free robustness produces, and itemize is smooth-going, flat appearance, can reach the yield of 100%, main operation of saving one deburring, is conducive to automated production, time saving and energy saving, effectively reduce product cost.
