Description
Technical field
The present invention relates to a kind of making tool of member for automobile, and in particular to a kind of abat vent chute Dual-head chamfering is controlled
Tool.
Background technology
Car blinds refer to being arranged in compartment to reach the device of the effect such as shading, heat-insulated, protection privacy.Common
The installation of car blinds only fills a chute up and down in vehicle window, then curtain installation therebetween, uses and is stirred with hand.
In fact, early in 1996, some domestic automobile ornaments producers have just started the upsurge of research and development curtain, but due to being limited by material
System, and the reason of scientific research strength deficiency, the product developed only has both sides side vistor, and the material used can not
Reach the effect of heat-insulated one side printing opacity, therefore market of not opening always, many producers are all forced to exit.Until macromolecule longitude and latitude
Cotton is applied on car blinds, has just reversed this situation.Macromolecule longitude and latitude cotton has good single plane fluoroscopy characteristic, Ke Yiyou
Ground is imitated by most of strong light blocking outside car, while keeps the certain brightness of in-car.In addition, longitude and latitude cotton can reduce moisture
It is lost in, reduces in-car degree of drying because of caused by strong illumination.Exactly because solving problem of materials, producer starts good window
Curtain market, the product of research and development also gradually enrich, and develop into and occur five width curtain today, i.e., in addition to four side windows, are kept off after connecting
Wind glass can also install curtain, and the desire to purchase of consumer also begins to be lighted again.
The installation and use of car blinds are, it is necessary to use chute.For the ease of installation car blinds and avoid damaging in use
Bad car blinds, incised wound human hand, the both ends of chute then need to carry out chamfering.Therefore being badly in need of can be to the chute both ends of car blinds
Carry out the device of automatic chamfering.
