Abstract
The invention discloses a spindle slide bearing bush material of a cotton picker and a preparation method thereof. The bearing bush material comprises the following elements in part by mass: 53-60 parts of Fe, 34-40 parts of Cu, 5-6 parts of Sn and 1-2.5 parts of C. The spindle slide bearing bush material of the cotton picker has remarkably improved wearing resistance and self-lubricating performance.
Description
Technical field
The present invention relates to a kind of color cotton machine and pluck ingot sliding bearing cover material and preparation method thereof.
Background technique
At present, the assembly of a core is arranged plucking spindle assembly at color cotton machine, the composition of plucking spindle assembly by: pluck ingot, pluck spindle support, cutting ferrule, pluck ingot sliding shaft sleeve A, pluck ingot sliding shaft sleeve B.The effect of pluck ingot sliding shaft sleeve A, plucking ingot sliding shaft sleeve B is that the harvesting that the ingot High Rotation Speed carries out cotton is plucked in supporting.Pluck ingot sliding shaft sleeve A, pluck ingot sliding shaft sleeve B and belong to powder metallurgy oil-impregnated bearing spare, owing to be subjected to total, the impact of the factors such as spatial position, pluck between ingot sliding shaft sleeve A and cutting ferrule and do not accomplish to seal completely, being easy to just have foreign matter in the cotton picking process enters and plucks ingot and pluck ingot sliding shaft sleeve A, go in the middle of plucking ingot sliding shaft sleeve B, can increase like this and pluck ingot and pluck ingot sliding shaft sleeve A, pluck the frictional force between the ingot sliding shaft sleeve B and aggravate to pluck ingot sliding shaft sleeve A, pluck the wearing and tearing of ingot sliding shaft sleeve B, when plucking ingot and plucking ingot sliding shaft sleeve A, pluck and pluck ingot when matching gap between ingot sliding shaft sleeve B acquires a certain degree and in the cotton picking process, can not take off being wrapped in the cotton of plucking on the ingot, affecting normal harvesting must change plucking spindle assembly, so the work of existing powder metallurgy oil-impregnated bearing under this rugged environment does not all reach requirement.
Summary of the invention
Goal of the invention of the present invention is: provide a kind of a kind of color cotton machine that is applicable under the complex environment to pluck ingot sliding bearing cover material and preparation method thereof, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of color cotton machine plucks ingot sliding bearing cover material, and by the quality deal, contained element is in this cage material: Fe is 53～60 parts, and Cu is 34～40 parts, and Sn is 5～6 parts, and C is 1～2.5 part.
A kind of color cotton machine as claimed in claim 1 is plucked ingot sliding bearing sleeve material preparation method, and this preparation method carries out as follows:
Step 1: in above-mentioned element ratio scope, the color cotton machine of preparation is plucked ingot sliding bearing sleeve total amount as required, extrapolates the quality of every kind of required elemental metals, and the establishment bearing housing is produced list of ingredients, and gets the raw materials ready by list of ingredients;
Step 2: selected batching fitted over to be placed in the special mixing plant together in proportion stir, the time of stirring is 30 minutes～40 minutes;
Step 3: the batching that will stir is placed on color cotton machine and plucks in the mould of ingot sliding bearing sleeve compressing;
Step 4: compressing bearing housing is carried out sintering, and temperature is controlled at lower sintering 25-35 minute of 700 degree～750 degree;
Step 5: the bearing housing behind the sintering is placed on boils oil in the deep fat, oil temperature is controlled at 70 ℃～100 ℃, boils oily 20-30 minute.
In step 5, boiling the used oil of oil is 46# machine oil.
Beneficial effect of the present invention:
Adjust by the prescription of color cotton machine being plucked the ingot sliding bearing sleeve, be enclosed within on wear resistance, the self-lubricating property and all be significantly improved so that new color cotton machine is plucked the ingot sliding bearing.
Embodiment
Embodiments of the invention: a kind of color cotton machine is plucked ingot sliding bearing cover material, and by the quality deal, contained element is in this cage material: Fe is 53～60 parts, and Cu is 34～40 parts, and Sn is 5～6 parts, and C is 1～2.5 part.

A kind of color cotton machine as claimed in claim 1 is plucked ingot sliding bearing sleeve material preparation method, comprise the steps: that a kind of color cotton machine plucks ingot sliding bearing cover material, by the quality deal, contained element is in this cage material: Fe is 53～60 parts, Cu is 34～40 parts, Sn is 5～6 parts, and C is 1～2.5 part.
A kind of color cotton machine as claimed in claim 1 is plucked ingot sliding bearing sleeve material preparation method, and this preparation method carries out as follows:
Step 1: in above-mentioned element ratio scope, the color cotton machine of preparation is plucked ingot sliding bearing sleeve total amount as required, extrapolates the quality of every kind of required elemental metals, and the establishment bearing housing is produced list of ingredients, and gets the raw materials ready by list of ingredients;
Step 2: selected batching fitted over to be placed in the special mixing plant together in proportion stir, the time of stirring is 30 minutes～40 minutes;
Step 3: the batching that will stir is placed on color cotton machine and plucks in the mould of ingot sliding bearing sleeve compressing;
Step 4: compressing bearing housing is carried out sintering, and temperature is controlled at lower sintering 25-35 minute of 700 degree～750 degree;
Step 5: the bearing housing behind the sintering is placed on boils oil in the deep fat, oil temperature is controlled at 70 ℃～100 ℃, boils oily 20-30 minute, and cotton machine of the present invention is plucked the ingot sliding bearing sleeve and contained tiny hole, in the process of boiling oil, the oil content of bearing housing can be controlled between 25%～30%.
In step 5, boiling the used oil of oil is 46# machine oil.
In step 4, sintering is a kind of powder or pressed compact to be heated being lower than under the key component melting temperature, makes to produce between particle to connect, to improve the existing method of product properties.
Boil the technological means that oil is the existing industry in the step 5, the bearing the inside after sintering is complete is oil-containing not, and this oil must boil oil into bearing inside by boiling oily operation, so just can play the effect of selflubricating.
