Embodiment 1

[0030] see first image 3 , in this example image 3 In the hot pressing die shown, the powder metallurgy method is used to make a bi-material or multi-material planar slide, which is used as a sliding bearing in textile machinery. The hot pressing mold structure includes an upper template 4, a lower template 5 and a mold cover 6, and the upper template 4, the lower template 5 and the mold cover 6 encircle the powder raw material feeding cavity and the molding cavity of the slider.

[0031] combine Figure 1-Figure 3 , the method for making the slider includes: using the second powder material 2 as the powder raw material for the supporting material layer, using the first powder material 1 as the raw material for the working material layer, laying materials in order, and using the second powder material as the powder raw material for the supporting material layer 2 on the bottom, the first powder material 1 as the raw material of the working material layer is on the top, and...

Embodiment 2

[0038] see still Figure 1-Figure 4 , the preparation target, the hot pressing mold used and the process adopted in this embodiment are basically the same as those in Example 1, and the interface structure template 3 adopted is also the same, the difference is that in the sequential laying of materials, The laid second powder material 2 and the first powder material 1 are both mixed with a binder with a volume content of 8%, and the second powder material 2, the interface construction template 3, and the first powder material 1 are laid in sequence. After that, degreasing and sintering are carried out. During the degreasing process, the interface structure template 3 is decomposed and removed together with the binder.

[0039] The final temperature of the above-mentioned degreasing process in this embodiment is based on the fact that the adhesive and the interface structure template 3 can be completely decomposed, and the processes of pressurization, degreasing and sintering i...

Abstract

The invention discloses a manufacturing method of a sliding part, the sliding part and a textile machine applying the sliding part. The manufacturing method of the sliding part is characterized in that a powder metallurgy method is adopted for manufacturing a double-material or multi-material plane sliding part such as a sliding bearing of the textile machine; a second powder material is used as asupporting material layer powder raw material; a first powder material is used as a working material layer raw material; the second powder material and the first powder material are laid in sequenceone below the other; a thin plate which is of a fluctuating structure and is made of a material capable of being thermally decomposed is placed between the second powder material and the first powdermaterial to serve as an interface construction template, and can be removed between the second powder material and the first powder material in a degassing pre-sintering or degreasing mode; and afterthe interface construction template is removed, the second powder material and the first powder material are respectively metallurgically sintered to form a supporting material layer and a working material layer, and a non-linear interface structure corresponding to the fluctuating structure of the interface structure template in shape is formed at the sintering interface of the supporting material layer and the working material layer. According to the method, powder does not need to be pressed separately, and an independent operation procedure for treating the interface does not need to be added.

Description

technical field [0001] The invention relates to the technical field of manufacturing mechanical sliding parts, in particular to a method for manufacturing a sliding part, a sliding part and a textile machine using the sliding part. Background technique [0002] Planar sliding parts such as sliding bearings are parts used to withstand sliding friction in mechanical equipment, and can adapt to low-speed and heavy-load working conditions. Bearings are widely used as friction pairs in textile machinery because they avoid the use of lubricating oil. [0003] Many planar bearings with self-lubricating ability are dual-material or multi-material bearings, which include a support material layer for support and at least one working material layer for friction and lubrication, so they can also be produced by powder metallurgy. In the process, the iron-based powder material is used as the powder raw material of the supporting material layer, and the copper-based powder material with s...
