Abstract
The utility model relates to a novel connecting rod device which comprises a connecting rod, wherein a steel cover sheath is arranged on the connecting rod, is internally provided with a shaft pin, and is composed of a steel sheath and a wear-resistant coating. According to the novel connecting rod device, the high-quality steel sheath is selected and is subjected to machining, thermal treatment and grinding, then a molybdenum disulfide powder layer is uniformly sprayed on an inner hole through a special device, and a coating with uniform thickness and high wear resistance is attached to the inner hole of the steel sheath by high-temperature treatment. The novel connecting rod device has high wear resistance and long service life.
Description
Technical field
The utility model relates to a kind of connecting rod means, is specifically related to a kind of injection machine connecting rod means.
Background technique
Injection machine approximately adopts the linkage type mold closing mechanism more than 90% at present, assembles steel bushing or copper sheathing in its connecting rod, easily occurs wearing and tearing in using process, and when particularly lubrication state was bad, wearing and tearing meeting aggravation had a strong impact on machine performance and life-span.(performance comparison sees the following form)
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of wear resistance good, the novel link device of long service life.
Technological scheme: in order to solve the problems of the technologies described above, a kind of novel link device described in the utility model, it comprises connecting rod, is provided with the coating steel bushing on described connecting rod, be provided with pivot pin in described coating steel bushing inside, described coating steel bushing is comprised of steel bushing and wear resistant coating.
Described wear resistant coating is the molybdenum disulfide coating.
Described coating steel bushing and pivot pin are rotationally connected.
The utility model is selected the high-quality steel bushing, and after processing, heat treatment, grinding are completed, by special device, endoporus evenly sprays one deck molybdenum disulfide powder, then passes through high temperature processing, and the steel bushing endoporus just adheres to the coating that a layer thickness is even, wear resistance is fabulous.
Friction factor low (reducing by 45%) when coating steel bushing described in the utility model and Chilled Hardened Steel slide, and the molybdenum disulfide coating is wear-resisting especially, through injection machine manufacturing works and use customers' place practical application test, coating steel bushing working life is more than 1.7 times of common steel bushing, is 2 times of left and right of copper sheathing.
Curing molybdenum layer in the utility model is under the relatively poor situation of lubrication state, its anti-dry friction performance is considerably beyond common steel bushing, so when in some injection machine user short time during (one to two class) machine mold closing mechanism insufficient lubrication, " interlock " situation can not appear in the coating steel bushing, and this point is very favourable to the serviceability of hoisting machine.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: each parts of the utility model are closely connected, compact structure, the molybdenum disulfide coating is set in steel bushing, greatly improved wear resistance, when described coating steel bushing and Chilled Hardened Steel slide, friction factor is low, can greatly improve whole service life like this, the realistic usage requirement of this product.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the wear extent comparison diagram of the steel bushing of coating described in the utility model and common steel bushing.
Wherein:
1, connecting rod; 2, coating steel bushing; 3, pivot pin; 4, steel bushing; 5, wear resistant coating
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As depicted in figs. 1 and 2, a kind of novel link device described in the utility model, it comprises connecting rod 1, is provided with coating steel bushing 2 on described connecting rod 1, is provided with pivot pin 3 in described coating steel bushing 2 inside, described coating steel bushing 2 is comprised of steel bushing 4 and wear resistant coating 5; Described wear resistant coating 5 is molybdenum disulfide coatings; Described coating steel bushing 2 and pivot pin 3 are rotationally connected.Each parts of the utility model are closely connected, the molybdenum disulfide coating is set in steel bushing, has greatly improved wear resistance, when described coating steel bushing and Chilled Hardened Steel slide, friction factor is low, can greatly improve whole service life like this, the realistic usage requirement of this product.
The utility model provides a kind of thinking and method; method and the approach of this technological scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, in the present embodiment not clear and definite each constituent element all available prior art realized.
