Description
Technical field
The utility model patent is related to automobile safety protective technical field, is a kind of metal and the compound automobile collision preventing of plastics
Beam.
Background technique
With the development of the automobile industry, automobile industry is higher and higher to the collision of automobile, lightweight performance requirement.In vehicle body
In the design of safety collision part, not only only need the safe performance indexes for meeting automobile, while also needing to meet light-weight design etc.
Many index.
First barrier of the collision prevention girders as vehicle passive safety, is connected with longitudinal beam, is to absorb and transmit dispersion
Foreign impacts power, the important safety for protecting vehicle body front and rear part.Orthodox car collision prevention girders are usually to be formed by punch welding,
Cross sectional shape is usually simple square shape, and when a vehicle is in a collision, on the one hand since structure is too simple, collision prevention girders cannot
Good absorption, transmitting dispersion impact kinetic energy, to injure the life of driver and passenger in the integrality for driving cabin structure and cabin
Life safety.Still further aspect is since collision prevention girders making material uses metal material, by external force collision dynamics and metal material
The influence of characteristic, collision prevention girders, which easily deform, to be distorted and is not easily repaired, and causes maintenance cost to rise, simultaneously because collision prevention girders are whole
It is big from weight, it is not suitable for current automotive light weight technology design requirement.
Recently as the rapid development of plastimets, pushed away using the auto parts and components that metallo-plastic is processed
To market, a kind of metal and the compound automobile buffer beam of plastics that the present invention exactly proposes in this context.The collision prevention girders ontology
Using plastics, it is internally embedded metal reinforcing, this aspect is effectively mentioned by the rigidity of toughness and metal material using plastics
The energy-absorbing of collision prevention girders and the ability of transmitting dispersion kinetic energy are risen, while improving the protective capacities of complicated collision and secondary collision.In addition
On the one hand the produced with combination for passing through metal and two kinds of different materials of plastics can effectively mitigate the own wt of collision prevention girders, and mould
Material can reduce the maintenance cost and manufacturing cost of automobile with recycling and reusing.Therefore the present invention is for promoting vehicle safety
Energy, light-weight design, cost savings all have great importance and are worth.
Summary of the invention
In order to overcome existing collision prevention girders to absorb and transmitting kinetic energy ability is insufficient, own wt is big, manufacturing cost is high
Problem, the utility model patent propose a kind of collision prevention girders using metal and plastic composite production.The collision prevention girders ontology
Using plastics, it is internally embedded metal reinforcing, passes through the mutual constraint using plastics and metallic property.So, effectively promotion anticollision
The energy-absorbing of beam and the ability of transmitting dispersion kinetic energy, improve the protective capacities of complicated collision and secondary collision.Mitigate collision prevention girders simultaneously
Own wt, reduce maintenance and manufacturing cost.
Technical solution adopted in the utility model is: choosing collision prevention girders production special plastic and plate thickness is 1.0mm-
The metal material of 6.0mm.Metal material is first cut into the plate of design requirement size, then the metal blank that cutting is completed is pacified
On dedicated production mold and Guan Bi mould, plastic raw materials are sent into heating melting in injection molding machine high temperature cylinder and are plasticized, then
Melt injects in die cavity, makes cavity full under pressure, after the pressure maintaining cooling treatment of certain time, makes metal blank
It is formed by curing one in conjunction with the material of melting, then opens mold and takes out product, is finally made metal and compound anti-of plastics
Hit beam.
It include the techniques such as the cutting preparation, insert assembling fixation, injection molding of metal material in specific manufacturing process.
One: metal material cutting.In conjunction with Service Environment, the collision prevention girders metal material that plate thickness is 1.0mm-6.0mm is chosen.
According to collision prevention girders geometric dimension and design requirement, metal material is cut into length with plate shearing machine, width is design requirement size
1 piece of plate.
Two: insert assembling is fixed.Prepare a set of collision prevention girders and make dedicated mold, the plate that cutting is completed is laterally embedding
Enter and be fixed into mold guide slots, and is closed upper/lower die.
Three: injection molding.Heating in the high temperature cylinder of injection molding machine, which is added, in collision prevention girders special plastic raw material makes its fusion plastification,
Again in melt injection die cavity, make cavity full under pressure, by the pressure maintaining cooling treatment of certain time
Afterwards, metal blank is made to be formed by curing one in conjunction with the material of melting, then open mold take out product, be finally made metal with
The compound collision prevention girders of plastics.
The advantages of the utility model patent is: structure is simple, easy to make, light-weight, and stability is good, can significantly improve
The absorption of collision prevention girders and the level of transmitting energy and the protective capacities of complicated collision, secondary collision.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is utility model diagram.
Fig. 2 is the left view schematic diagram of Fig. 1.
1. plastic material body in figure, 2. metal material Materials.
Specific embodiment
The nylon plastic material of [embodiment 1] side length 1100mm width 35mm height 75mm and the compound anticollision of cold-pressed steel plate
Beam.
One: metal material cutting.In conjunction with Service Environment, 1 piece of collision prevention girders cold-pressed steel plate that plate thickness is 2.5mm, root are chosen
According to collision prevention girders geometric dimension and design requirement, it is 1100mm that cold-pressed steel plate, which is cut into side length with plate shearing machine, and width is 35mm's
1 piece of plate.
Two: insert assembling is fixed.Prepare the collision prevention girders that a set of running channel height is 75mm and make particular manufacturing craft, will cut
At plate be laterally embedded into the guide groove of mold and be fixed, and be closed upper/lower die.
Three: injection molding.Heating in the high temperature cylinder of injection molding machine, which is added, in collision prevention girders special-purpose nylon plastic raw materials makes its melting
Plasticizing, then in melt injection die cavity, make cavity full under pressure, after the pressure maintaining cooling treatment of certain time,
So that metal blank is formed by curing one in conjunction with the material of melting, then opens mold and take out product, be finally made side length
1100mm width 35mm height 75mm metal and the compound collision prevention girders of plastics.
