Problems solved by technology

[0005] In the above prior art, due to the use of manual operation for helical spring stacking, it is difficult to form automation in the manufacture of porous elastic pads, and the operation efficiency is low
Moreover, the density of the elastic metal composite material layer of the elastic metal plastic tile is difficult to control, and the elasticity can only be roughly guaranteed to be uniform, so that the overall elasticity of the composite material layer is within a range, resulting in a difference in the elastic modulus of the finished elastic metal plastic tile. Larger, the product performance cannot be further improved

[0040] Such as Figures 1 to 5 The structure of the elastic metal plastic tile of the first embodiment is shown. The elastic metal-plastic tile 100 includes a tile base 10 , a composite resin layer 20 and a plurality of connecting columns 30 . The composite material resin layer 20 is fixed to the connection surface of the tile base 10 . The second end of the connection post 30 is fixedly connected to the connection surface of the tile base 10 , the height of the connection post 30 is smaller than the thickness of the composite material resin layer 20 , and the tile base 10 and the composite material resin layer 20 are fixed by a plurality of connection posts 30 .

[0041] Wherein, the connecting column 30 includes a guiding portion 31 and a main connecting portion 32 . The cross-sectional area of ​​the guide portion 31 gradually increases from the top of the first end toward the second end. The main connection portion 32 is located between the guide portion 31 and the tile ...

[0050] Figure 7 It is a structural schematic diagram of the connecting column of the elastic metal-plastic tile according to the third embodiment of the present invention. In the third embodiment, the connecting column 50 includes a guide portion 51 and a main connecting portion 52 formed of a cone. The main connecting part 52 includes a circular post 521 with a diameter equal to the maximum diameter of the guide part 51 and a toothed part 522 between the guide part 51 and the post 521 . The toothed portion 522 includes a plurality of annular teeth arranged at intervals in sequence. Preferably, the rim of the ring tooth is thinner than the root of the ring tooth. In a modified embodiment, since the dedendum of each annular tooth is relatively thick, there may be no space between each annular tooth.

Abstract

The invention provides an elastic metal-plastic bush and a manufacturing method thereof. The elastic metal-plastic bush comprises a bush base (10), a composite resin layer (20) and a plurality of connecting columns, wherein the composite resin layer (20) is fixed on a connecting surface of the bush base (10), each connecting column comprises a first end and a second end which are arranged oppositely, the second ends are fixedly connected with the connecting surface of the bush base (10), the height of the connecting columns is smaller than the thickness of the composite resin layer (20), and the bush base (10) and the composite resin layer (20) are fixed through the connecting columns. According to the elastic metal-plastic bush and the manufacturing method of the elastic metal-plastic bush, the bush base is connected with the composite resin layer through the connecting columns, so that the automation of the connection between the connecting columns and the bush base can be realized, the manufacturing efficiency of the composite resin layer can be increased, the automation of production is then realized, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the field of bearings, more specifically, to an elastic metal-plastic tile and a manufacturing method thereof. Background technique [0002] The elastic metal plastic tile is a sliding bearing mainly used in the thrust or guide bearing of the hydroelectric generator set, and forms a friction pair with the mirror plate or shaft. The structural characteristics of elastic metal plastic tiles in the prior art are: the connection surface of the tile base made of metal (generally low carbon steel) is brazed with a composite material resin layer, and the friction surface of the elastic metal plastic tile is reinforced and modified PTFE resin. [0003] The manufacturing process of elastic metal-plastic tiles in the prior art is generally to use metal wires with a diameter of about 0.4 mm to be wound into spiral springs, piled up in multiple layers, and after reaching the weight required by the process, pressurize and press in the mold...
