Detailed description of the invention
For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
Caterpillar block is the core part of crawler belt, and the connector engaged with driving wheel fluted disc is housed above, and contact the induction tooth play the guiding role with bearing wheed, its weight accounts for more than 60% of crawler belt gross weight.Therefore, the innovative design of caterpillar block, to crawler belt expendable weight, improves life and reliability and plays a crucial role.The present invention is directed to existing casting caterpillar block Combination property not high, the problems such as the comparatively large and welding caterpillar block processing technology of split caterpillar block loss in efficiency is complicated, propose the solid forging caterpillar block of a kind of high strength for continuously tracked vehicle, long life, good, the easy installation of maneuvering performance.
This Integral forge type caterpillar block, as shown in Figures 2 and 3, comprising:
The plate body 1 of two truss structures;
Connection seat 2, it is arranged between the plate body 1 of described two truss structures, connects two plate bodys 1 respectively;
The each integral type in each described plate body 1 rear and front end is provided with pin-and-hole 4, composition double-pin pore structure; Described plate body 1 edge is evenly equipped with reinforced rib 3, and described plate body 1 and the one side of earth surface are provided with several spuds 5;
The technique that the plate body 1 of described two truss structures, connection seat 2, reinforced rib 3, pin-and-hole 4 and spud 5 are added by the shaping rear machine of Integral die-forged is combined into an integral type closing structure;
Wherein, in forging process, forging Joint face of a pattern 6 is arranged on the line of centers of two pin-and-holes 4.
Wherein, described caterpillar block material adopts steel 42CrMo-GB3077-88.
Wherein, in described Integral die-forged process, after heat treatment, hardness is HB401 ~ 461 (d=3.1 ~ 2.85); Selective hardening HRC >=53, spud position.
According to the feature of caterpillar block discontinuity, caterpillar block integral structure is complex-shaped, and the thickness in each cross section is different.Have the reinforced rib 3 that annular is closed, the thickness of muscle is reasonable in design, is connected with plate body rounding off; Spud 5 position requires that hardness is high, and resistance to abrasion is good, and tack is strong, can effectively prevent from breakking away; Pin-and-hole 4 position requires to bear higher extrusion stress and shearing stress, and requires that resistance to abrasion is good, toughness is high.Connection seat 2 forms firmly integral type closing structure with the reinforced rib 3 of plate body 1 surrounding, the outer wall in double-pin hole 4, improves the Longitudinal stiffness and transverse stiffness of caterpillar block, to eliminate between plate body relative torsion and bending, alleviates the load of bearing pin.
This caterpillar block adopts material to be steel 42CrMo-GB3077-88, after bakingout process, hardness reaches HB401 ~ 461 (d=3.05 ~ 2.85), selective hardening HRC >=53, spud position, can meet the operating needs of 15 ~ 30 tonnes of continuously tracked vehicle behavioral systems.
In forging process, forging Joint face of a pattern 6 is chosen on the line of centers in double-pin hole 4, so that the machine of follow-up pin-and-hole adds, can ensure the right alignment requirement in double-pin hole.The stability of product can be improved, can also effective guarantee forging manufacturability.
The technological process of this solid forging caterpillar block as shown in Figure 1.
Concrete technology flow process is: after raw MAT'L blanking, is heated to the high temperature of 1120 ~ 1150 DEG C, with the die hammers of 5 tons forging and molding at 850 DEG C.After finish-forging, with 600 tons of Clipping press trimmings in trim die, trimming temperature is not less than 800 DEG C; In grand master pattern thorax, correct profile, Tc is not less than 750 DEG C, and timely pressurized air blows the oxide skin in forging die groove off; After inspection oad is qualified, after being heated to 840 DEG C, with oil quench, be then heated to 380 DEG C, insulation 120 ~ 150min tempering, sampling observation hardness reaches HB401 ~ 461 (d=3.1 ~ 2.85); Adopt shot-blasting machine cleaning forging oxide skin, check with or without forging defect; Final 100% exterior check, beats the qualified marking.
To sum up, the invention provides a kind of novel overall forging caterpillar block.It is mainly used in crawler belt heavy-duty vehicle, heavy transportation machinery, construction machinery and equipment endless track installation.On the basis not changing caterpillar block material, by improving plate body structure, manufacturing process and job operation, make the mechanical characteristics of caterpillar block and reliability more can meet the demand of novel crawler vehicle development.This caterpillar block adopts contour forging technique one-body molded, has good combination property, lightweight, life-span length, withstanding corrosion, easily processes, the advantages such as easy installation.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
