Abstract
The invention discloses a manufacture process of a passenger car bumper. The manufacture process is characterized by comprising the following steps: A. material feeding; B. cropping; C. material storing; D. punching; E. transition swing bridge; F. guiding; G. rolling/roll bending formation; H. implementation of cutting off; I, joint welding; J. crator clearing; K. electrophoresis; and L. package. Passenger car bumper has high product technological content, is good in market price, light in weight, and suitable for the light weight development of the automobile industry and meanwhile coincides with the development concepts of safety, environmental protection and energy conservation in the automobile industry.
Description
Technical field
The present invention relates to a kind of manufacture craft of manned vehicle bumper/spoiler.
Background technology
The manned vehicle bumper/spoiler has good energy-absorbing, buffer action, but classification can be divided into two kinds of aluminum magnesium alloy, high-strength alloy plates with regard to material, because the aluminum magnesium alloy cost is higher, the sectional area shape matching is simple, cause energy-absorbing effect can not give full play to, and its selling price is generally than high-strength alloy plate expensive 30～40%.And the high-strength alloy plate is by calculating and design can obtain comparatively complicated sectional area shape, again due to its wall thickness of high-strength alloy plate 1mm only, therefore can reach the weight-saving purpose equally.The manufacturing process of alloy sheets is mainly by roll-forming, although disposable input is larger, efficiency is very high, in general high strength situation, only needs just can produce in two minutes a manned vehicle safe buffering beam.
Utilize the high-strength characteristic steel plate, attenuate is the application target of high strength manned vehicle bumper/spoiler.The tensile strength of strengthening high strength manned vehicle bumper/spoiler is 35-45 kgf/millimeter
2level, be mainly used in vehicle-body outer panel, but for requiring more high-intensity part can't meet.For this reason, further having developed than the complex tissue type high tensile steel plate had excellent moldability of traditional precipitation hardening type bumper/spoiler is the cardinal task of current auto manufacturing.Because tensile strength is not less than 80 kgfs/millimeter
2level, be used in bumper back beam and born on the easy parts that are shaped such as side door of shock, and being applied on the side door frame.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of manufacture craft of manned vehicle bumper/spoiler, be by grade of steel is selected and the composition adjustment, carry out again surface and timeliness processing after roll-in/roll forming, welding, to improve its mechanical characteristics.
Technical scheme of the present invention is achieved in the following ways: a kind of manufacture craft of manned vehicle bumper/spoiler comprises the following steps:
A, material loading: coiled strip internal diameter: ф 508mm, decoiling unit harmomegathus scope ф 465-550mm;
B, crop: otch need to become vertical with the blank line of centers, shearing thickness: 1-2mm; Blank width: 500mm; There is pinch device and operator's station independently;
C, storing: according to blank width design stock chest;
D, punching: device fabrication producer can manufacture and design according to technological requirement, guarantees the manufacturing line continuous working, and punching position is accurate;
E, transition pendulum bridge: need to guarantee the manufacturing line continuous working, shut down during the welding of change of lap crop;
F, guiding:
G, roll-in/roll forming: suitable material: Docol860/B500LA, sheet thickness 1～2mm, maximum width 500mm, roll-in speed: maximum speed 10m/min;
H, cut-out: while guaranteeing to cut off, cutting knife is vertical with workpiece, and fracture is neat.Length tolerance is controlled in 1mm;
I, total welding connect: the assemblies such as weldering left and right support, tank bracket, nut;
J, cleaning crator:
K, electrophoresis:
L, packing.
The present invention, product technology content is high, and the market price is good, lightweight, is applicable to auto-industry lightweight development.Also coincide very much auto trade safety, environmental protection, energy-conservation idea of development simultaneously.The specific embodiment
A kind of manufacture craft of manned vehicle bumper/spoiler comprises the following steps:
A, material loading (decoiling unit).Coiled strip internal diameter: ф 508mm, decoiling unit harmomegathus scope ф 465-550mm;
B, crop.Otch need to become vertical with the blank line of centers.Shearing thickness: 1-2mm; Blank width: 500mm; There is pinch device and operator's station independently;
C, storing (according to blank width design stock chest);
D, punching (punch).Device fabrication producer can manufacture and design according to technological requirement, but needs to guarantee the manufacturing line continuous working, and punching position is accurate;
E, transition pendulum bridge device manufacturer can manufacture and design according to technological requirement, but need to guarantee the manufacturing line continuous working, during the welding of change of lap crop, shut down;
F, guiding (track adjusting wheel);
G, roll-in/roll forming (rolling press).Suitable material: Docol860/B500LA etc.Sheet thickness 1～2mm, maximum width 500mm.Roll-in speed: maximum speed 10m/min(calculates at roller sheet basic diameter 190mm), the actual roller speed processed of using is by manufacturing process determination;
When H, cut-out (joist shears) guarantee to cut off, cutting knife is vertical with workpiece, and fracture is neat.Length tolerance is controlled in 1mm;
I, total welding connect (assemblies such as weldering left and right support, tank bracket, nut);
J, cleaning crator (inspection has or not solder skip, dry joint, overlap);
K, electrophoresis (cooperation processing is returned factory inspection and received);
L, packing.
