Abstract
The invention relates to a novel connection rod device. The device comprises a connection rod. The connection rod is provided with a coated steel sleeve. A shaft pin is arranged in the coated steel sleeve. The coated steel sleeve is composed of a steel sleeve and a wear-resistant coating. The coated steel sleeve is prepared by the following steps: selecting a high-quality steel sleeve, processing the steel sleeve, subjecting the steel sleeve to a thermal treatment, then grinding the steel sleeve, making the steel sleeve go through a special apparatus to uniformly spray a layer of molybdenum disulfide powder on the inner hole, and then subjecting the steel sleeve to a high-temperature treatment so as to form a wear-resistant coating with a uniform thickness in the inner hole of the steel sleeve. The novel connection rod device has the advantages of good wear resistance and long service life.
Description
Technical field
The present invention relates to a kind of connecting rod means, be specifically related to a kind of injection machine connecting rod means.
Background technique
Injection machine more than approximately 90% adopts linkage type mold closing mechanism at present, assembling steel bushing or copper sheathing in its connecting rod, and easy appearance wearing and tearing in using process, when particularly lubrication state is bad, wearing and tearing can aggravate, and have a strong impact on machine performance and life-span.(performance comparison sees the following form)
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, provides 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 of the present invention, it comprises connecting rod, is provided with coating steel bushing on described connecting rod, is provided with pivot pin in described coating steel bushing inside, described coating steel bushing is made up of steel bushing and wear resistant coating.
Described wear resistant coating is molybdenum disulfide coating.
Described coating steel bushing and pivot pin are rotationally connected.
The present invention selects high-quality steel bushing, and after processing, heat treatment, grinding complete, by special device, endoporus evenly sprays one deck molybdenum disulfide powder, then passes through high temperature processing, and 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 of the present invention and Chilled Hardened Steel slide, and 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 the more than 1.7 times of common steel bushing, is 2 times of left and right of copper sheathing.
Curing molybdenum layer in the present invention is under the 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 when (one to two class) machine mold closing mechanism insufficient lubrication, coating steel bushing there will not be " interlock " situation, and this point is very favourable to the serviceability of hoisting machine.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the each parts of the present invention are closely connected, compact structure, molybdenum disulfide coating is set in steel bushing, greatly improve wear resistance, when described coating steel bushing and Chilled Hardened Steel slide, friction factor is low, can greatly improve like this whole service life, the realistic usage requirement of this product.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the wear extent comparison diagram of the steel bushing of coating described in the present invention 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 present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of novel link device of the present invention, it comprises connecting rod 1, on described connecting rod 1, is provided with coating steel bushing 2, is provided with pivot pin 3 in described coating steel bushing 2 inside, described coating steel bushing 2 is made up 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.The each parts of the present invention are closely connected, and molybdenum disulfide coating is set in steel bushing, have greatly improved wear resistance, and when described coating steel bushing and Chilled Hardened Steel slide, friction factor is low, can greatly improve like this whole service life, the realistic usage requirement of this product.
The invention 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 the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each constituent element all available prior art realized.
