Effective protection is played the role of at touching, double of 1 medial surface of elbow body middle part, meanwhile, enhancing lug boss 101 is set as carbon fibre web
The installation of layer 102 provides condition, and 102 effective position of carbon fiber stratum reticulare is mounted in half elbow body, 1 medial surface
Near portion, to carbon fibre material is effectively combined in half elbow body 1, enhances lug boss 101 and carbon fiber stratum reticulare 102 is matched
Cooperate the service life for improving half elbow body 1 jointly.
In the present embodiment, enhancing 101 outer surface of lug boss is the arcwall face to half elbow body, 1 medial surface direction protrusion,
The design of the arcwall face can effectively reduce the frictional force between enhancing 101 outer surface of lug boss and material, and it is suitable to be conducive to material
Arcwall face surface pass through, meanwhile, enhancing 101 outer surface of lug boss be outwardly convex arcwall face, with arcwall face in the middle part of
The friction that the friction impact being subject to is larger, arcwall face two sides are subject to is impacted lesser operating condition and is matched, in half elbow body 1
After using for a longer period, enhance the arcwall face being gradually worn down at lug boss 101 to being adapted with half elbow body, 1 medial surface,
And carbon fiber stratum reticulare 102 is (to enhance at lug boss 101 at this time to the arc of half elbow body, 1 lateral surface direction protrusion at this time
It is the arcwall face being recessed inwardly with carbon fiber stratum reticulare 102, the two keeps relatively parallel state) so that in half elbow body 1
The carbon fiber stratum reticulare 102 of side center uniformly leaks out, and entire half elbow body, 1 medial surface center is in carbon fiber stratum reticulare
Under 102 protection, the characteristics such as wear-resisting of carbon fiber stratum reticulare 102 are effectively played, making for half elbow body 1 is significantly improved
Use the service life.
When being combined to carbon fibre material in half elbow body 1, a distinct issues are that carbon fibre material is placed in
When in half bent tube type chamber 2, on the one hand carbon fibre material is easy to be washed away by molten iron in molten steel pouring course, is on the other hand difficult to protect
The unfolded state in planar is handled, in the step D of the present embodiment, after carbon fibre web is gradually immersed into melting from bottom to top first
In molten iron, then carbon fibre web is taken out, forms carbon fiber stratum reticulare 102 after carbon fibre web cooled and solidified, above method can incite somebody to action
Carbon fibre web flexible is prefabricated into the carbon fiber stratum reticulare 102 with certain rigidity, and carbon fiber stratum reticulare 102 is then bent into arc
Shape finally by the region in 102 snap-in type chamber lower die 4 of carbon fiber stratum reticulare for enhancing 101 moulding by casting of lug boss, and controls carbon fiber
Tieing up stratum reticulare 102 is the arc to 3 direction protrusion of type chamber upper mold, wherein for enhancing 101 moulding by casting of lug boss in type chamber lower die 4
Region, on the one hand entirely enhance lug boss 101 for moulding by casting, on the other hand being caught in for carbon fiber stratum reticulare 102,
It is middle because carbon fiber stratum reticulare 102 has certain elasticity, both ends can be easily stuck in type chamber lower die 4 for enhancing lug boss
The region of 101 moulding by casting.
Embodiment 2
