Abstract
The utility model relates to a composite sliding bearing which comprises an outer material layer and an inner material layer, wherein the surface of the inner material layer is provided with a plurality of peak valley waves higher than the inner material layer, and the surface of the outer material layer is provided with a plurality of wave-shaped metallurgical bonding surfaces tightly integrated with the peak valleys and valley peaks of the inner material layer. In the composite sliding bearing disclosed by the utility model, a plurality of wave-shaped convex valley peaks higher than the inner material layer are formed on the bonding surface of the outer material layer and the inner material layer by the explosive welding, the peak valleys and valley peaks on the bonding surface of the outer material layer and the inner material layer are tightly fit to form the integral metallurgical bonding surface of mutually infiltrated materials, and the outer material layer and the inner material layer can not slide. The composite sliding bearing can be mechanically processed at random, and has the advantages of large bearing capability, solid combination and no separation phenomenon. According to the composite sliding bearing, any two or more mechanical materials can be arbitrarily selected for welding according to the requirements to the mechanical performance of a product.
Description
Technical field
The utility model relates to a kind of compound sliding bearing, belongs to machinery manufacturing technology field.
Background technique
The conventional composite profile shaft holds explained hereafter such as general employing press-fits, centrifugal pressure casting, built-up welding, has and can not carry out any machining, in conjunction with not firm easy disengaging, carry defectives such as little.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of compound sliding bearing is provided.
The compound sliding bearing of the utility model; Comprise external-talent's layer and interior material layer; The material laminar surface has a plurality of peak valley waves that exceed interior material layer in said, and said external-talent's laminar surface has the waveform metallurgy combination face of a plurality of and interior material range upon range of mountains paddy-tight interdependent one integrated mass in paddy peak.
The compound sliding bearing of the utility model on the junction plane of external-talent's layer and interior material layer through explosive welding form exceed in a plurality of wavy projection peak valley of material layer; The junction plane paddy peak-peak valley of external-talent's layer and interior material layer fits tightly; Form the metallurgy combination face that material interpenetrates one integrated mass, any slippage can not take place in external-talent's layer and interior material layer.Can carry out any type of machining, carry greatly,, can require to select two or more mechanical property material welding arbitrarily according to the product mechanical property in conjunction with firmly not breaking away from.
Description of drawings
Fig. 1 is the structural representation of the compound sliding bearing of the utility model;
Schematic representation in the explosive welding process of the compound sliding bearing of Fig. 2 the utility model.
Wherein, 1 is external-talent's layer, and 2 is interior material layer, and 3 is the metallurgy combination face, and 4 is explosive and detonator, and 5 are the blast crack, and 6 is die sleeve, and 7 is core rod.
Embodiment
As shown in Figure 1; The compound sliding bearing of the utility model; Comprise external-talent's layer 1 and interior material layer 2; There are a plurality of peak valley waves that exceed interior material layer 2 on material layer 2 surface in said, and there is the waveform metallurgy combination face 3 of a plurality of and interior material layer 2 peak valley-tight interdependent one integrated mass in paddy peak on said external-talent's layer 1 surface.
The preparation method of the compound sliding bearing of the utility model comprises pretreatment, explosive welding, annealing in process, four operation stages of fine finishing moulding,
Wherein, technique for pretreating is: 1) according to product requirement, the form size of material layer core rod and external-talent's layer die sleeve is made core rod and die sleeve in confirming; 2) the internally junction plane of material layer and external-talent's layer polishing rust cleaning; 3) clean junction plane with gasoline, remove greasy dirt, dry quick-fried fully.
Explosion weld process is: 1) select suitable explosive; 2) the inside and outside layer material of assembling composite sliding bearing; 3) core rod 7 and die sleeve 6 are installed; 4) on 1 on die sleeve 6 and external-talent's layer, or core rod 7 and 2 on interior material layer are laid explosive and detonator 4; 5) ignite: material layer 2 produces wave metallurgy combination face 3 with external-talent's layer 1 in making through explosive blast, and both stiffly combine, and process compound sliding bearing blank;
Annealing treating process is: the compound sliding bearing blank after the explosive welding is put into annealing furnace annealing, eliminate the internal stress that explosive welding produced.
Fine finishing moulding technology is: compound sliding bearing blank is carried out fine finishing, make it to become the composite sliding bearing finished product.
Claims (1)
