Embodiment 1

[0028] a. Use a semi-soft copper-clad steel wire (copper-clad steel composite wire or copper-plated steel wire) with a diameter of 0.35-0.45mm to make a helical spring section. The outer diameter of the helical spring is 2.6-3.3mm, and the pitch is 2-4mm. The length is 25-45mm, spread the spiral spring segments evenly in the forming mold in a disorderly manner, limit and press to make the metal wire elastic pad 2 blank;

[0029] b. Cover the surface plastic layer on the metal wire elastic pad 2 blank, and mold and compound it into a tile surface blank;

[0030] c. Sintering the tile surface blank to make a tile surface with a surface plastic layer 3 embedded on the wire elastic pad 2;

[0031] d. Brazing the tile surface containing solder on the steel tile base 1, that is, it is made as figure 1 The shown product includes a steel tile base 1 on which copper-clad steel wire helical spring elastic pads arranged in disorder are firmly combined, and the copper-clad steel wire hel...

Embodiment 2

[0033] a~c are the same as embodiment 1;

[0034] d. Place the tile surface in an airtight container, and immerse the metal wire elastic pad 2 in liquid solder under the condition of a vacuum of 6-15 Pa, so that the solder is filled into the pores in the metal wire elastic pad 2. cooling, to solidify the solder;

[0035] e. Brazing the tile surface containing solder on the steel tile base 1 .

Embodiment 3

[0037] Others are the same as in embodiment 1 or 2, except that the copper-clad steel wire helical spring segment is spread in the molding die with a magnetic bottom plate, and then other steps are carried out.

Abstract

The present invention discloses a high-strength elastic metal plastic bearing liner. It includes steel bearing base, on the steel bearing base a metal wire elastic pad is firmly combined, and a surface plastic layer is inlaid on the metal wire elastic pad, the described metal wire elastic pad is a disordered arranged copper-covered steel wire helical spring elastic pad. Besides, said invention also provides its production method and concrete steps.

Description

Technical field: [0001] The invention relates to a heavy-duty thrust elastic metal-plastic bearing bush of a hydroelectric generator set and a production method thereof, in particular to a high-strength elastic metal-plastic bearing bush and a production method thereof. Background technique: [0002] At present, the elastic metal-plastic bearing pads all have a steel tile base, and a metal-plastic composite tile surface is brazed on the steel tile base. [0003] The existing technology close to the technology of this patent application has the Chinese patent No. 90103367.7, the invention patent named "Elastic Thrust Pad and Manufacturing Method", the disclosed technical solution is "using tin bronze as the porous material, mixing the surface with lead The elastic tile made of the modified surface plastic as the filling material and the manufacturing method thereof. "Its tin bronze porous material is composed of a number of tin bronze wire coil springs with a diameter of 0.4...
