Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, With reference to embodiment
The present invention is described in further detail.
The present invention the following steps are included:
A. rolling formation.
In view of the structure of heavy vehicle frame spandrel girder is substantially equal section U-shaped girder construction, equal section U-shaped beam shapes just
It is the advantage place of rolling formation.Wide in variety additionally, due to vehicle frame spandrel girder, batch is small, and there are many different outer widths and material daily
The spandrel girder of think gauge produces, and facilitates 3 cutting off tools this requires roll shape line has the transformation of 1 coiled strip wrap function, 2 technological parameter
It cannot frequently replace.
The chief component of roll shape line has: feeding system, smoothing unit, (including deburring), goes to end at unwinder unit
Unit rolling formation (including be oriented to and correct) unit and cutting unit, blanking system.
Workflow are as follows: automatic charging, uncoiling, smooth, go end, deburring, rolling formation, correction, fixed ruler cutting, from
Dynamic sub-material.
Machinable sheet thickness 4-10 millimeters of the line；U-shaped 188-350 millimeters of part width dimensions of roller pressure, prestissimo
For 24 meters/min.Machining accuracy: load-bearing web, aerofoil straightness: 1/1000, it is 6 millimeters maximum.Process characteristic: production efficiency
Height, stable product quality, product Length x Width thickness can be at any time according to product requirement adjust automaticallies.
B. punching.
There are many process that can be carried out spandrel girder hole machined, such as die punching, plane numerical controlled punching, plane numerical controlled brill
Hole, radial drilling machine drilling etc..These processing methods because of its own feature difference, also deposit by working ability, processing quality, logistics mode
In biggish difference, but from the point of view of process flow, they have one what is common is that the hole machined of spandrel girder is arranged at forming
Preceding realization, subsequent forming will then realize that hole position accuracy is affected by forming by mold.
The present invention is punched out using three face numerical control punching machines.The load-bearing soffit of girder after the processable forming of three face numerical control punching machines
Hole on face and upper and lower two aerofoils.Complete machine generally has 4 punching units, and two are arranged on lathe vertical plane, processes load-bearing
Hole on soffit of girder face；In addition two are arranged in the left and right sides in machine tool horizontal face, process the hole of lower aerofoil on spandrel girder.Its punch die
It arranges using in-line arrangement, rather than rotary type tower is arranged, so mould replacing time is short.
Process characteristic: stable product quality, precision are high.Flexibility degree is high, and the new product Operational preparation time is short, for holding
It is only programming time that the hole Chong Liang, which changes Operational preparation,.It quickly can adequately meet the requirement in market and each user.Production
Efficiency is more high than plate stamping, and the spandrel girder in piece 300 hole of processing only needs 6-7 minutes.
C. it cuts.The present invention uses plasma cut.
Since spandrel girder is different in size, workshop is laid out and technology arrangement limits and dust removing effects requirement, workpiece front and back end is cut
The secondary positioning of tapping, and it is mobile not influence workpiece, positioning device requires liftable；Spandrel girder front end aerofoil cutting quantity is big,
Through engineer testing, moderate finite deformation can be generated in cutting process, in this way when cutting aerofoil, the outside of belly must be compressed, and cut the outside of belly
When pressing device must unclamp, such pressing device must laterally and can move up and down；Cutting waste material is longer and amount is big, and falls
It cannot influence to produce when waste material, therefore 2 ash cans are set and are placed on transverse movable trolley；Cutting generates volume of smoke and powder
Dirt need to close cutting, and need to take dust suppression.
D. ball blast.
The steel that automobile frame spandrel girder uses are hot rolled steel plate, and material thickness is at 4-10 millimeters.It must be driven off before coating
Oxide skin and corrosion.Traditional descales and derusts using acid cleaning process.But that there are acid mists is big for pickling, cause Pickling-shop and
The corrosion of the Steel structure equipment of surrounding workshop, cleaning the shortcomings that sediment pollutes environment more after water consumption is big and pickling, gradually
It is eliminated by steel and auto manufacturing.And impeller blasting technique is at relatively advanced machinery that a kind of pair of steel derust
Reason method, not only high production efficiency, but also have expense low, high degree of automation is, it can be achieved that pile line operation environmental pollution is small
The characteristics of, gradually it is widely used by steel and auto manufacturing.
It is determining whether ball blast technique can be used before spandrel girder surface treatment, is first having to determine the surface after ball blast
Can quality meet spandrel girder paint quality.Vehicle frame factory vehicle frame paint technique used at present is anodic electrophoresis process, paint film thickness
Degree is only capable of reaching 20 microns, and this requires surface of steel plate ball blast rear surface quality requirement is relatively high.Through engineer testing ball blast
Back plate surface roughness is required less than 6 microns, and derusting grade requires to reach Sa2.5 grades.And consider process rhythm matching, ball blast workpiece
To reach 8 meters/min by speed.
As pellet diameter 0.4-0.8mm, hardness HRC40-50；Ball blast rear panel roughness is less than 6 microns.Derusting etc. at this time
Grade reaches Sa2.5 grades, and salt spray resistance and acid-cleaning plate are close to no significant difference.
E. it corrects.
F. it bends.Bending uses bar folder, and step is stepped up for 1 using fixture；2 carry out first time bending；3 unclamp fixture simultaneously
Workpiece is moved forward；4 step up again；5, which carry out second, bends；6 release fixtures are offline by workpiece.
Die forming is replaced with roll-in, die punching is replaced with three face numerical control punchings, replaces mold to fall with plasma cut
Expect deburring, substitute pickling with ball blast technique, high degree of automation, Flexible Manufacture ability is strong, and reliable performance is easy to operate, produces
Quality is stablized, and the requirement of Multi-varieties and Small-batch Production is fully met.
