Abstract
The invention provides a kind of forming method of aluminium alloy car door and window frame.It is the method that adopts " squeezing curved " with the section bar blank of the aluminium alloy car door and window frame end squeezing type membranous type chamber from the type film.Thereby obtain the section bar product consistent with die cavity.This aluminum alloy door shape can be the hyperspace geometry.Employing the technology of the present invention fabircated shapes blank can prevent wrinkling and subside, and also can eliminate the resilience of product, can save large complicated special purpose machine tool and a large amount of subsidiary engine accessories, reduces equipment investment and production cost of products, and can well guarantee the quality of product product.
Description
The present invention is the manufacturing process of the no machining of shape.Be a kind of manufacturing process of aluminium alloy car door and window frame specifically.
At present, the domestic blank that still belongs to of technology that is shaped for aluminium alloy car door and window frame.Abroad, complicated for the section material section shape, adopt large complicated numerical control bending machine to make its shaping for the aluminium alloy car door and window frame of complex space geometry is general again.With Audi's 100 car front door upper window frames is example, and this window frame profile is an aluminium alloy, and its cross section is the hollow unsymmetrical section, and it is shaped as six rates of curving on four frees degree, is that the complex space geometry of crooked deformation and distortion (is seen Fig. 1～Fig. 4).West Germany adopts then that large-sized numerical control multidimensional bending machine is equipped with multiple Aided Machine, aid is produced.The equipment complexity expends substantial contribution.
At above-mentioned defective, the object of the present invention is to provide a kind of manufacturing process of aluminium alloy car door and window frame.
The present invention is the method that adopts " squeezing curved " with the section bar blank of the aluminium alloy car door and window frame end squeezing type membranous type chamber from pattern, thereby obtains the section bar product consistent with die cavity.
Pattern involved in the present invention mainly is made up of upper and lower pattern, mould bases and guide pin bushing etc., and its equipment and frock are extremely simple, can turn over system according to the model and the master body of section bar product, and perhaps direct product parts figure according to the section bar product processes.The pattern material can be selected steel, cast iron or composite for use according to the product size.
Adopt method of the present invention processing transverse shape and spatial geometric shape all the section bar product of complicated section bar blank gained can avoid because the variation of the section configuration that effect took place of bending stress and the variation of wall thickness, if the section bar of hollow section also can be avoided wrinkling and subside.And can save large complicated special plane and a large amount of subsidiary engine accessory.Reduce equipment investment and shorten equal tens times of trial-produce period.Thereby reduce production costs significantly.
In a word, method provided by the present invention is applicable to the shaping production of the section bar product of various complex sections, complex space geometry, be particularly useful for having the shaping of the aluminium alloy car door and window frame of complex space geometry, and can well guarantee the quality of product product.
Fig. 1 is the front view of Audi's 100 car front door upper window frame multi-dimensional spatial structures.
Fig. 2 is the side view of Audi's 100 car front door upper window frame multi-dimensional spatial structures.
Fig. 3 is the meaning view of Audi's 100 car front door upper window frame multi-dimensional spatial structures.
Fig. 4 is the sectional schematic diagram of Audi's 100 car front door upper window frame section bars.
Fig. 5 is for adopting the work schematic diagram of method of the present invention and pattern processing Audi 100 car front door upper window frame section bar blanks.
Specify embodiment of the present invention below in conjunction with accompanying drawing:
With processing Audi 100 car front door upper window frames is example.See Fig. 1～Fig. 4: this window frame is a hyperspace geometry.See Fig. 5: pattern is fixed on the pillar die set, top swage (1), after anvil swage (2) closure, guide pin bushing (3) is fixed on the pattern, again the window frame profile blank is pressed into die cavity through guide pin bushing (3) from an end of pattern by horizontal press push rod (4), and the process die cavity withstands on the backup plate (5), the section configuration of die cavity is consistent with the window frame profile section, at this moment, because the effect of extruding force makes the skew of section bar neutral line and produces certain " creeping ", thereby prevented when being shaped that section bar is wrinkling and subside (and can exempt the necessity that adds plug), also can eliminate the resilience of product, the track that section bar is walked is identical with cavity shape.Open pattern then, take out product.
Claims (3)
1, a kind of manufacturing process of aluminium alloy car door and window frame is characterized in that: it is the method that adopts " squeezing curved " with the blank of the aluminium alloy car door and window frame end squeezing type model cavity from pattern, and the track that section bar is walked is identical with cavity shape.
2, the manufacturing process of aluminium alloy car door and window frame according to claim 1 is characterized in that the track that the section bar blank is walked is the hyperspace geometry in die cavity.
3, the manufacturing process of aluminium alloy car door and window frame according to claim 1 is characterized in that the section bar blank withstands on the backup plate through behind the die cavity, makes material production " creeping ".
