Abstract
This application discloses a kind of foaming stent and foamed products, foaming stent includes rack body, the connecting pole stretched out close to edge from the side of rack body, by connecting pole and the fixed rebound piece of rack body；The rebound piece is parallel to the rack body and protrudes from the side of rack body.Therefore part is interfered with vehicle body sheet metal during the application not only solves the problems, such as automotive body welding, it is also ensured that filling effect of the foamed products in gap made of foaming stent.
Description
Technical field
The disclosure relates generally to auto parts, and in particular to a kind of foaming stent and foamed products.
Background technology
With the continuous development of auto industry, requirement of the people to automobile increasingly diversification, from the power and speed of early stage
Degree requirement, is gradually upgraded to the requirement to comfort, and standard is higher and higher, however the comfort of automobile (is made an uproar with auto NVH
Sound, vibration and sound vibration roughness) performance is closely bound up, and the sealing of vehicle also contributes to the NVH performances of automobile, the partition of cavity
Importance also just more highlights, especially at positions such as the A of automobile, B, C rear wheel covers, increase cavity blocking and sound-absorbing soundproof effect compared with
Good material has a distinct increment to the whole NVH performances of automobile.It is limited however, as technique, parts can only be in bodywork cavity
Be welded workshop installation, if the circulation that can influence painting dressing automobiles electrophoresis liquid if workshop installation is welded, causes partition position can not
It the hidden danger such as is caused to get rusty by electrophoresis liquid, so the part requirements of cavity partition are needed in the workshop installation that is welded, but left for
After electrophoresis, partition will be unprecedentedly blocked before baking again for the correlation space of Painting Shop electrophoresis circulation.
Before car body electrophoretic, the temperature being subject to is not high, however after electrophoresis, into after the process of coating baking,
The bulk temperature of vehicle body is very high, and between reaching 150 to 180 DEG C, therefore the difference between temperature in use is a kind of special
Material solve the above problems, the technique energy that injection is passed through by using the expanding material of PA66 (polyamide 66) and research and development
The variously-shaped of customer requirement is enough made, cavity is carried out after being toasted in the case of can not influencing electrophoresis after installation is welded
Partition.
This any intumescent material solves the problems, such as that cavity partition has for quite a long time, and also increasingly approach is ripe；It is past
Toward the technique that in parts Earlier designs, can not learn the workshop that is welded, the cavity that can only separate as needed is designed；But
It is when PA66 is used to add this part that expanding material is molded, also due to the interference during welding and assembling technics is asked
Topic cause it is difficult to install, automation matching degree it is not high；Since part framework and intensity are ensured by PA66, but due to
After moulding, acceptable largest deformation is limited, often during weld car automobile body welding for PA66 this material
Interfered with vehicle body sheet metal, lead to that welding and assembling technics have some setbacks or parts are damaged in installation process, if according to work
Skill process is designed can not so be bonded with cavity shape, can not ensure filling effect, if necessary to preferable filling effect
It then needs to add new part, is not easy to part management.
Invention content
In view of drawbacks described above of the prior art or deficiency, being intended to provide one kind can solve zero during automotive body welding
Part ensures that the foaming stent and foamed products of filling effect with vehicle body sheet metal interference.
First aspect the application offer includes rack body, the connection stretched out from the side of rack body close to edge
Column, the rebound piece for being fixed on connection column end；The side of the rebound piece protrudes from the side of rack body.
According to the technical solution that the application provides, the angular range of the connecting pole and rack body and rebound piece is 70
- 90 degree of degree.
According to the technical solution that the application provides, the rebound piece includes point rebound piece that two panels is fixed on connecting pole；
The gap for filling-foam material is formed between two panels point rebound piece.
According to the technical solution that the application provides, the side of the connecting pole is offered for the recessed of filling-foam material
Slot.
According to the technical solution that the application provides, the length range of the connecting pole is 0.5mm-1.5mm.
According to the technical solution that the application provides, the material of the rack body is toughening type PA66.
Second aspect the application also provides a kind of foamed products, which includes above-mentioned foaming stent, cover board and folder
Expanded material between foaming stent and cover board；It is detachably connected between the foaming stent and cover board.
According to the technical solution that the application provides, the rebound piece includes point rebound piece that two panels is fixed on connecting pole；
The gap for filling-foam material is formed between two panels point rebound piece.
According to the technical solution that the application provides, the angular range of the connecting pole and rack body and rebound piece is 70
- 90 degree of degree.
According to the technical solution that the application provides, the side of the connecting pole is offered for the recessed of filling-foam material
Slot.
The advantageous effect of the application is：The application by foaming rack body edge set connecting pole and rebound piece,
The design position of connecting pole is rack body and plates of automobile interference surface；So that made of foaming stent foamed products by
When interference, rebound piece can be rotated and be twisted around connecting pole to avoid interfering, during due to mounting process process
Between it is shorter, be not enough to allow toughening type PA66 that permanent deformation occurs, interference disappearance, the rebound being staggered while process is completed
Piece springs back to script design position under the screen resilience of toughening type PA66；Therefore the application not only solves vehicle bodywork soldering termination process
The problem of middle part is interfered with vehicle body sheet metal, it is also ensured that filling effect of the foamed products in gap made of foaming stent.
The foamed products that the application provides are made of 3 detachable parts, and three parts assemble up whole as one
Body parts.Zero foamed products that part is divided into the quadric injection mould of three parts than in the prior art are more effective when being molded production
Rate can more easily reach the tolerance of higher standard in production size.
The application can limit the foamed material of central part using both sides foaming stent and the designing scheme of cover board clamping board type
The direction of expansion allows expanding material to foam towards defined direction, reaches more preferably partition and filling effect.
