Abstract
The present invention discloses a production method of elastic metal plastic bush. It is characterized by that said production method includes the following steps: on the metal wire elastic pad makingbush surface in which a surface plastic layer is inlaid; placing the bush surface in a closed container, under the condition of that vacuum degree is 6-15 Pa soaking the metal wire elastic pad in liquid soldering material to make the soldering material be filled into pores in the metal wire elastic pad, then soldering the bush surface containing soldering material on the steel bush base.
Description
Technical field:
The present invention relates to the production method of a kind of hydraulic generator unit with the heavy-loaded thrust bearing elastic metal plastic bearing.
Background technology:
At present, elastic metal plastic bearing all has base steel, and soldering has the compound tiling of wire elastic pad and plastics on base steel.Because thinking, traditional concept must leave certain hole in the wire elastic pad, could obtain bigger elastic modelling quantity, for this reason, existing elastic metal plastic bearing in process of production, all be the wire elastic pad to be immersed under normal pressure in the liquid solder such as tin, the hole filling rate in the wire elastic pad is usually less than 80%.Yet, under normal pressure to the production method of wire elastic pad immersed solder material, do not increase the elastic modelling quantity of wire elastic pad, on the contrary can be owing to can not get filling the cavity district and the hole that form of wire elastic pad deep hole (greater than 20%) are filled the reason that the degree of depth does not wait, cause the elastic modelling quantity of product to reduce and inhomogeneous, be not suitable under heavily loaded industrial and mineral, using.
Summary of the invention:
The present invention is in order to solve the low and uneven problem of existing in prior technology elastic modelling quantity, a kind of high elastic modulus that has to be provided, being suitable for the production method of the elastic metal plastic bearing of use under the heavily loaded industrial and mineral.
Technical solution of the present invention is: a kind of production method of elastic metal plastic bearing is characterized in that comprising the steps:
A. be formed in the tiling that is embedded with surperficial plastic layer on the wire elastic pad;
B. tiling being placed closed container, is under the condition of 6～15Pa the wire elastic pad to be immersed in the liquid solder in vacuum, and scolder is inserted in the hole in the wire elastic pad;
The tiling soldering that c. will contain scolder is on steel tile base.
Described a step is to make spiral spring section with wire, and unordered even spreading is in the mould with magnetic force base plate.
Described sintering tiling blank is to be 2～10Pa with the tiling blank in vacuum, and temperature is a sintering under 375～395 ℃ the condition, and sintering time is 60～90 minutes, lowers the temperature naturally with stove and comes out of the stove.
The present invention has overcome the technology prejudice that prior art " must leave certain hole in the wire elastic pad; could obtain bigger elastic modelling quantity ", employing hole in the wire elastic pad under vacuum condition is filled the production method of scolder, the hole filling rate that makes scolder is greater than 95%, even can reach 100%.High hole filling rate can avoid forming filler cavity district in the wire elastic pad and hole is filled the problem that the degree of depth does not wait, and has improved the elastic modelling quantity and the uniformity of product, can improve 5～10%, is particularly suitable for using under heavily loaded industrial and mineral.On magnetic sheet, magnetic sheet will make the metallic elastic pad more smooth to the suction of wire spiral spring section with the unordered even spreading of copper-clad wire spiral spring section, and the uniformity of the compound precision of surperficial plastic layer, elastic modelling quantity all is improved, and especially can improve 4000cm
2The compound precision of above extra-size tile dough model material has prolonged service life of product, has enlarged the range of application of product; Carry out compound tiling blank sintering under vacuum condition, can avoid the aerial oxidation of wire, make between the metal spiral spring, combine more firmly between wire and the steel tile base, reliability of products further improves.
The specific embodiment:
Embodiment 1:
A. be formed in the tiling that is embedded with surperficial plastic layer on the wire elastic pad by existing method;
B. tiling being placed closed container, is under the condition of 6～15Pa the wire elastic pad to be immersed in the liquid solder such as tin in vacuum, and scolder is inserted in the hole in the wire elastic pad, cools off, solidifies scolder;
The tiling soldering that c. will contain scolder is on steel tile base.
Embodiment 2:
Other is with embodiment 1, just a step be with the unordered even spreading of spiral spring section in mould with magnetic force base plate.
Embodiment 5:
Other is with embodiment 1 or 2, is 2～10Pa with the tiling blank in vacuum just, and temperature is a sintering under 375～395 ℃ the condition, and sintering time is 60～90 minutes, lowers the temperature naturally with stove and comes out of the stove.
