Technical Field

The invention relates to the technical field of oil-retaining bearings, in particular to an inner hole forming device for an oil-retaining bearing.

Background

Porous bearings (Porous bearings) are oil-impregnated bearings which are made of metal powder as the main raw material and are sintered bodies produced by powder metallurgy, are inherently Porous and have technical advantages such as the number, size, shape and distribution of pores being relatively freely adjustable during the production process.

The oil-retaining bearing has the characteristics of low cost, vibration absorption, low noise, no need of adding lubricating oil and the like in a longer working time, and is particularly suitable for a working environment which is not easy to lubricate or is not allowed to be polluted by oil. Porosity is an important parameter for oil-impregnated bearings. The oil-containing bearing working under high speed and light load requires a large oil content, and the porosity is preferably high; the oil-retaining bearing working at low speed and large load requires high strength and is suitable for low porosity.

When the oil-retaining bearing is manufactured in a powder metallurgy mode, the error of the inner hole of the oil-retaining bearing is large and does not meet the production requirement, so that the inner hole is generally formed by punching. When the oil-retaining bearings need to be processed in batches, workers are required to firstly place the oil-retaining bearings below the stamping rod and take out the oil-retaining bearings after stamping is completed, and the steps are circulated in sequence, so that labor cost is high, and efficiency is low.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the technical problems of high labor cost and low efficiency of batch punching of inner holes of the traditional oil-retaining bearing are solved.

The invention provides an inner hole forming device for an oil-retaining bearing, which comprises a rack, wherein the rack is provided with:
