End is connected to one structure with hinge column 1, and 6 both ends of cavity communicate with the hinge hole 2 in two hinge columns 1, are based on respectively
Above structure, the processing technology of the connecting rod is using integrated cast molding.
Specific embodiment, as shown in Figure 1 to Figure 3, the distance between both sides side plate 3 are identical with the diameter of hinge column 1, both ends
The distance between hinge hole 2 is 1113mm, a diameter of 131mm of hinge hole 2, and 1 wall thickness of connecting rod hinge column increases to by 35mm
40mm, the thickness of side plate 3 increase to 35mm by 30mm, and the thickness of upper reinforcing plate 4 and lower reinforcing plate 5 is 35mm, the entirety of connecting rod
Weight increases to 503kg, upper reinforcing plate 4 and lower reinforcing plate 5 by existing 453kg and the link position of both sides side plate 3 is located at side
At the non-edge of plate 3, setting in this way causes upper reinforcing plate 4 and lower reinforcing plate 5 as supporting role of the reinforcing rib to two side plates
More preferably, the height of side plate 3 is identical with the height of hinge column 1, and the distance between both sides side plate 3 is identical with the diameter of hinge column 1, even
The material of all constituents of bar is No. 45 steel, and connecting rod is integrally formed using casting, at present, when casting it is widely used be
CO2- sodium silicate sand is mostly formulated by the sodium silicate of pure quartz sand addition 4.5%~8.0%, but for
Large-scale steel-casting tens of tons of, quality requirement is high, all using facing sand or part using magnesia, chromite sand, olivine
The special sands such as sand, zircon sand replace quartz sand advantageously, and some requirement sodium silicate sand has certain wet strength and plasticity,
To blow CO2 hardening after demoulding again, 1%~3% bentonite (mass fraction) or 3%~6% unselected clay can be added in
Sand (mass fraction) adds in part of clay sand.For improve knockability, can also add in 1.5% sawdust (mass fraction) or add
Enter 5% asbestics (mass fraction) or the other additives of addition.
As shown in Figures 4 to 7, the processing technology step of connecting rod is as follows in the present invention：
A, making first mold identical with connecting rod outer profile provides standby connecting rod outer contour shape by the first Mold Making
Arenaceous shell, and arenaceous shell includes the upper arenaceous shell 7 of two-piece unit and lower arenaceous shell 8；
B, internal second mold with the inner cavity identical with cavity 6 and 2 shape of hinge hole is made, the second mold includes upper
The mold 9 of lower split and lower mold 10 fill core sand so as to form and 2 shape of cavity 6 and its both ends hinge hole in the lumen
Sand core 11 is mounted on corresponding position in arenaceous shell by identical sand core 11；
C, casting gate is provided on arenaceous shell, No. 45 molten steel are cast along casting gate, temperature during casting for 1450 DEG C-
1500 DEG C, eventually form connecting rod casting；
D, casting being heat-treated, heat treatment includes normalizing, quenching and tempering successively, and normalizing temperature is 850 degrees Celsius,
Hardening heat is 840 degrees Celsius, and temperature is 600 degrees Celsius, and the hardness of casting after quenching, before tempering is in HRC55-
Between HRC62；
E, casting is surface-treated and is finished, be surface-treated the ball blast to be carried out on shot-blasting machine, finishing packet
It includes and bore hole finishing is carried out to hinge hole with boring machine.
Connecting rod is formed by welding using steel plate in the prior art, it is high to the intensity requirement of steel plate, using Q460 Q550 materials
Matter, the Material Strength is higher, is not easy bending, and is connected to reinforcing rib in steel plate internal welding in prior art construction, reinforcing rib it
Between there are closed cavities, it is impossible to using integrally casting processing method, the mode of welding can form strength weak point in weld again,
The link mechanism hollow cavity used in the present invention is communicated with hinge hole, which can use the mode of integrally casting to be added
Work, and cost is reduced using the material of No. 45 steel, if the wall thickness of connecting rod does not increase, the connecting rod of No. 45 steel casting and formings
Intensity do not reach requirement, if the wall thickness of connecting rod increases excessive, the preponderance of connecting rod.
In the prior art using steel plate welding procedure, steel plate is standard size, it is only necessary to be welded after cutting, institute
The size for having component will not change, and in cast sections, due to casting can there are 2% retraction, if it is considered that this point,
Size so after casting will be less than normal and cannot meet actual needs, therefore, is considered as increasing in the preparation stage of casting
For large scale to adapt to amount of recovery, the Internal periphery size of arenaceous shell answers big by 2%, the outer profile ruler of sand core compared with the outer profile size of connecting rod
The size of the very little inner cavity compared with connecting rod is small by 2%, and after pouring, the outer profile size of connecting rod is inwardly contracted to desired size, connecting rod
Interior chamber size be contracted to required size outward.
Heat treatment stages after casting, successively by the way of normalizing, quenching and tempering, 850 degrees Celsius of normalizing temperature,
It can homogenize crystal grain refinement and distribution of carbides, remove the internal stress of material, and can casting be improved with refined cast structure
The machinability of forging piece lays the first stone for subsequent finishing, and 840 degrees Celsius of hardening heat, the purpose of quenching is to make
Cold austenite carries out martensite or bainite transformation, obtains martensite or bainite structure, then coordinates subsequent 600 degrees Celsius
Tempering process, the effect of tempering is the internal stress being reduced or eliminated in quenched steel component or reduces its hardness and strength, to carry
Its high ductility or toughness, the hardness of casting after quenching, before tempering between HRC55-HRC62, just can guarantee in this way through
The hardness crossed after tempering is moderate.After quenching and tempering, intensity, hardness, the wearability of steel-casting increase, but not shadow
Cutting ability is rung, and fatigue strength and toughness are greatly improved, it will so as to meet use of the connecting rod on coalcutter
Ask, since the rod surface after casting is more coarse, need increase ball blast process is surface-treated, hinge hole it is a diameter of
130.9-131.1mm, due to being the finishing to endoporus, and the hinge hole needs to carry out axis hole with shaft in finished product use
Cooperation, it is more demanding to the size of the inner surface of the hinge hole, the finishing that boring machine is used to carry out endoporus is needed to reach hinged
The required precision in hole, and use other processing methods then not easy to operate or the required precision of hinge hole cannot be reached.
