Abstract
The invention discloses a kind of core muscle for automobile pipeline bending, including core muscle body, bent support binding face is provided with the one end respective tube curved way of the core muscle body.This is used for the core muscle reasonable in design of automobile pipeline bending, the end that core muscle is ensure that when pipeline bends is with the direction movement of bending, enlarged contact areas, with the laminating of tube wall inner tight, ensure pipeline bending circularity, pipeline knee surface configuration is full, it is ensured that flow during automobilism in pipeline, percent defective is low, and product quality concordance is good；And core muscle simple structure, is easy to make, low cost.
Description
Technical field
The present invention relates to automobile pipeline technical field, more particularly, to a kind of core muscle for automobile pipeline bending.
Background technology
As automobile industry constantly develops, for the quality of automobile various aspects pursues higher.Main engine plants are for automobile
The requirement more and more higher of pipeline, in the middle of pipeline production, pipeline knee circularity also has corresponding requirement.
Existing core muscle occurs the phenomenon of the incongruent probability of flat curved, elbow roundness in forming elbow, pipeline it is curved
Bent percent defective is high, and product quality stability is poor.
The content of the invention
Not enough for prior art, the technical problem to be solved is to provide a kind of for automobile pipeline bending
Core muscle, to reach the purpose for ensureing that pipeline bends circularity.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：
This is used for the core muscle of automobile pipeline bending, including core muscle body, the one end respective tube bend of the core muscle body
Bent place is provided with bent support binding face.
Further, the bent support binding face is adapted with the curved surface at respective tube curved way.
The core muscle body includes canned paragraph and inserting paragraph, and bent support binding face is located at the end of inserting paragraph.
It is tip that the core muscle body arranges the end of bent support binding face.
Internal diameter of the diameter of the inserting paragraph less than or equal to pipe ends.
The end of the canned paragraph is provided with fixing screwed hole along the axis of core muscle.
The present invention compared with prior art, with advantages below：
This be used for automobile pipeline bending core muscle reasonable in design, the end that core muscle is ensure that when pipeline bends with
The direction movement of bending, enlarged contact areas, and the laminating of tube wall inner tight, it is ensured that pipeline bends circularity, pipeline bending
Place's surface configuration is full, it is ensured that flow during automobilism in pipeline, percent defective are low, and product quality concordance is good；And core
Muscle simple structure, is easy to make, low cost.
Description of the drawings
Below the content and the labelling in figure expressed by each width accompanying drawing of this specification is briefly described：
Fig. 1 is core muscle structural representation of the present invention.
Fig. 2 is pipeline brake forming schematic diagram of the present invention.
In figure：
1. pipeline, 2. pipeline knee, 3. core muscle body, 301. bent support binding faces.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, further details of is made to the specific embodiment of the present invention
Explanation.
As depicted in figs. 1 and 2, this is used for the core muscle of automobile pipeline bending, including the core muscle body 3 of cylinder, core muscle sheet
Body 3 includes canned paragraph and inserting paragraph.
At the one end respective tube curved way of core muscle body 3,2 are provided with bent support binding face 301, i.e. bent support laminating
Face is located at the outer end of inserting paragraph.
Bent support binding face 301 is adapted with the curved surface at respective tube curved way.Inside enlarged contact areas, and tube wall
Closely fit, it is ensured that pipeline bends circularity, pipeline knee surface configuration is full, it is ensured that stream during automobilism in pipeline
Amount.
It is tip that core muscle body 3 arranges the end of bent support binding face, and the diameter of inserting paragraph is less than or equal to pipeline end
The internal diameter in portion.Facilitate insertion in pipeline 1, and support can be provided to pipe ends, it is ensured that molding effect.The end edge of canned paragraph
The axis of core muscle is provided with fixing screwed hole, fixed easy.
Length direction on the bent support binding face of core muscle body 3 along core muscle is provided with chute, be provided with chute slide block and
Spring, the outer surface of slide block is arc-shaped curved surface, and tip setting of the spring in chute by core muscle, slide block are connected with spring, spring
Mobile slide block can be made to reset.Slide block on core muscle is in the slide block that ensure that when pipeline bends as the direction of bending is moved
It is dynamic, improve secure support, it is ensured that pipeline curved surface shape is full.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented
Restriction, if employ the improvement of various unsubstantialities that the design of the present invention and technical scheme are carried out, or it is not improved will
The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
