Abstract
The utility model provides a wear resistant bucket arm connecting member structure. The structure comprises a bucket arm connecting member body with an internal hole; the right end surface of the bucket arm connecting member body is embedded with a complex carbide wear resistant ring; a first welding step is arranged on the excircle at the left end surface of the bucket arm connecting member body; a second welding step is arranged at the middle part of the excircle of the bucket arm connecting member body; and a plurality of internal hole closing laser reinforcing rings are arranged in an inner bore of the bucket arm connecting member body at intervals. Compared with the conventional thermally processed and reinforced bucket arm connecting member, the wear resistance of the composite wear resistant bucket arm connecting member is improved by more than 15 times, and the composite wear resistant bucket arm connecting member can be widely used for bucket arm connecting members or corresponding connecting members of machines such as excavators, rock drilling machines, shovel cars, shovel loaders and mining machine.
Description
Technical field
The utility model relates to a kind of wear-resistant dipper connector structure, especially a kind of anti abrasive dipper connector structure that is applicable to machineries such as excavator, hammer drill, forklift, loader and digger.
Background technology
Dipper is widely used critical components such as all kinds of excavators, hammer drill, forklift, loader and digger; The dipper connector is connected with swing arm and is in three-body abrasive wear duty and complex stress condition for a long time; Working environment is also with corrosion, when the dipper connector worn and torn or corrosive wear after, the rotating connector fit clearance is increased; Making machine when work, lateral impact take place rocks; Service life of equipment shortens, and the replacing of dipper connector wear out failure rear connectors is complicated, and maintenance cost is higher.
Traditional dipper connector is an overall structure; Being generally the direct machine of forged steel forms; Its intensifying method is dipper connector integral quenching heat treatment reinforcement, the modified heat treatment reinforcement of the said dipper connector employing 45# medium carbon steel of patent CN201520991U; Dipper connector end face platform is further carried out hard surfacing strengthen, adopt bush structure at endoporus.Decrease welding rod and be machined to platform at dipper connector end face build-up wear-resistant, certain effect is arranged to improve dipper connector end face abrasion resistance properties.Employing also is widely used to the end face carburizing of global formation dipper connector or its abrasion resistance properties of nitriding method raising.Aspect structure design, improve relative motion friction pair material and kinematic system; Improve methods such as processing and device precision and improve the abrasion resistance properties of dipper connector and improve application life, the said dipper connector of patent CN2683707Y endoporus adopts the T jacket to cooperate with the motion of pin to improve connector.Traditional endoporus LASER HEAT TREATMENT adopts barber-pole stripes, grid striped, axial vertical bar striped etc.; Frictional force is very big when endoporus rotatablely moves with axle; Axle is along with endoporus laser stripe change in location when rotation cooperates; Rugged concavo-convex platform causes that the fitting face circular runout changes, and increases wearing and tearing.Still have deficiency from above technological practical effect, far can not satisfy the performance requirement of heavily loaded machine.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the prior art, and a kind of simple in structure, function admirable is provided, and stablizes, easy and simple to handle, anti abrasive dipper connector structure.
For realizing above-mentioned purpose; The anti abrasive dipper connector of the utility model structure; Comprise the dipper connector body that has endoporus, the right side of dipper connector body is embedded with the wear-resistant ring of double carbide, and the left side cylindrical of dipper connector body is provided with the first welding step; The cylindrical middle part of dipper connector body is provided with the second welding step, and the endoporus of dipper connector body is interval with a plurality of endoporus sealing laser reinforcing rings.
Described dipper connector body is that the middle carbon forged steel of modified heat treatment reinforcement is processed; The thickness of the wear-resistant ring of described double carbide is 0.2～1.2mm, and width is 20～60mm; The spacing of a plurality of endoporus sealing laser reinforcing rings of the interior span setting of said dipper connector body is 8～20mm, and width is 2～10mm, and the degree of depth is 2～5mm.
Beneficial effect: anti abrasive dipper connector structure of the present invention improves more than 10～15 times than the unitarily formed abrasion resistance properties that traditional T type lining, bush structure, modified heat treatment add the dipper connector of medium carbon steel dipper connector single piece that surface induction hardening strengthens, surface chemistry heat treatment reinforcement.Demand such as excavator under double carbide is wear-resistant dipper connector end face structure fully satisfies three-body abrasive wear and the corrosion operating mode; Endoporus annular laser reinforcing speckle reduces the wearing and tearing of dipper connector and pin; Store the friction, lubrication medium between the sealing stiffener rings, improve the Wear and Sliding Wear Properties of Organic between connector endoporus and the bearing pin.Avoid changing the installation trouble of connector, have wide range of applications.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-dipper connector body; The wear-resistant ring of 2-double carbide; 3-endoporus sealing laser reinforcing ring; The 4-second welding step; The 5-first welding step.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further description:
The anti abrasive dipper connector structure of the utility model; Mainly be made up of the dipper connector body 1 that has endoporus, double carbide is wear-resistant ring 2, endoporus sealing laser reinforcing ring 3, dipper connector body 1 is processed for the middle carbon forged steel of modified heat treatment reinforcement; Have annular groove on the right side of dipper connector body 1; Being embedded with thickness in the annular groove is the wear-resistant ring 2 of double carbide of 0.2～1.2mm; Double carbide is wear-resistant ring 2 apart between the inside and outside footpath, right side of dipper connector body 1 from being 5～20mm; Double carbide is wear-resistant, and ring 2 is formed by HVAF (weldering) or plasma spraying (weldering) moulding, and its endless belt width is 20～60mm.The left side cylindrical of dipper connector body 1 is provided with the first welding step 5; The cylindrical middle part of dipper connector body 1 is provided with the second welding step 4; The endoporus of dipper connector body 1 is interval with a plurality of endoporus sealing laser reinforcing rings 3; The spacing of a plurality of endoporus sealing laser reinforcing rings 3 is 8～20mm, and width is 2～10mm, and the degree of depth is 2～5mm.
