Description
Technical field
The present invention relates to the Machine Design of numerical control punching production line, control system and Computer-aided manufacturing field, particularly relate to the processing method of the adaptive mould of automobile longitudinal beam flat plate punching.
Background technology
Automobile longitudinal girder is the important component part of vehicle frame, vehicle frame manufacture craft has two kinds usually, one is the subsequent techniques such as coiled strip roll-forming (U-shaped) → U-shaped beam punching → cutting → bending, the second be longeron shear → dull and stereotyped punching → longeron compressing → riveted joint wait subsequent technique.To the punching of the second vehicle frame manufacture craft middle plateform by three kinds of different implementation methods, the production in enormous quantities efficiency high flexibility difference cost that first large hydraulic press is once suppressed for approved product is high, it two is better by longeron flat digital controlled eyelet work product line punching efficiency degree of precision, and it three is with boring the low low precision of drilling efficiency.The present invention is with the flat digital controlled eyelet work product line of longeron for goal in research, and in the dull and stereotyped longeron punching production line of automobile flat plate longeron, its punch pattern exists following shortcoming at present:
1, punching speed is slow, and it is slow that the main frame due to each Numerical control production line only has the mode of one-shot (once can only rush a hole) this one-shot to determine speed, and efficiency is low.
2, punching low precision, because group hole completes by two moulds or by twice punching of a mould, send in process at dull and stereotyped longeron, there are many factors can affect punching precision, the shake of beam when these factors comprise the repetitive positioning accuracy of leading screw, clamp exchanges, the alignment error of the mould of different station same size, the error of perpendicularity, opposite clearance error etc. of lathe.
Along with the standardization and seriation of the multi items high-quality heavy goods vehicles of automobile industry independent research and technological innovation, to the punching precision of vehicle frame and the requirement of efficiency more and more higher, existing hole-punching method can not meet the requirement of current automobile industry to punching precision and efficiency, in order to improve punching precision and process velocity, propose intelligent machining method, realize the high-speed, high precision processing of dull and stereotyped longeron.
(1) prior art is analyzed process time: the punch pattern of a dull and stereotyped longeron single host punching processing only has one and large main frame one-shot; Its process time, Tz was
①
Znum＝n ②
Wherein: Ts is the time of single host one-off hole-piercing,
for single host rushes the time sum in n hole; Znum: total hole count
The circulating time of each main frame, except outside the Pass having with power, speed, air pressure, has following proportionate relationship:
1. and 2. known by formula, due under prescribed conditions, Ts be constant when, shorten Tz, reducing n is most effective method.
(2) realize analyzing intelligentized process time
The punch pattern added after two punching has two kinds of i.e. single host one-shot, the two punchings of single host; The proportionate relationship of various punch pattern and circulating time is as follows:
A dull and stereotyped longeron process time Tz and total hole count be:
Tz=
③
Znum＝i1+i2×2 ④
3. formula with 1. compare, due to i1+i2<=n
As long as have the hole of two punching in drawing so process time in being less than process time 3. in formula 1. formula, speed improve number determined by the hole count of two punching.
