Problems solved by technology

[0002] The manufacturing of circulators in the prior art is processed by forming tools, and a piece of metal is cut into the shape of the circulator. However, the cost of the tool is high and the process is cumbersome and time-consuming; another manufacturing method is lost-wax casting, but there are still Its inherent limitations include low good rate, difficulty in repairing burrs caused by the parting line, and labor-intensive problems; there is also a circulator that is plastic injection molded, but it is difficult to open the mold for the hollow part, making the mold It must be dismantled into several pieces, affecting product accuracy, and difficult to refurbish. The above-mentioned problems affect the industry. Therefore, in order to break through the above-mentioned problems, a Metal Injection Molding (MIM) manufacturing method was devised to solve the above-mentioned problems, and the good rate is high. It's a good way to cost

Embodiment Construction

[0021] See first figure 1 , figure 2 ,image 3, Figure 4 , Figure 5 and Image 6 Shown, a kind of circulator of the present invention and manufacturing method, during implementation: the circulator of the present invention and manufacturing method, be the circulator that is applied on the bearing of linear motion, comprise the following steps:

[0022] Medium forming 1. Lubricating substances (such as wax, etc.), powdery polymer materials (such as polyethylene, or polypropylene, etc.), after material selection, add binders, such as paraffin, polyethylene, polypropylene, etc. Stir evenly (you can use a kneading mixer at a temperature between 50 degrees and 100 degrees), and then inject the molding medium from the mold;

[0023] The medium positioning 2 is to place the formed medium spirally bent circular cylinder 6 in the circulator mold 8;

[0024] MIM molding 3 is a rough blank mold 10 that is made by injecting metal powder 9 from the circulator mold 8 and covering the...

Abstract

The present invention relates to a production method of circulator used on linear motion bearing. Said production method includes the following steps: intermedium formation: using lubricant material and high-molecular material, etc. and adding adhesive, stirring them uniformly, utilizing mould to eject the formed intermedium; positioning intermedium: placing the formed intermedium into a circulator mould; MIM formation: ejecting meal powder from the circulator mould and covering said intermedium to form rough blank mould; degreasing and removing adhesive from rough blank mould; sintering the rough blank mould at high temperature, finishing and cooling so as to obtain the invented circulator.

Description

technical field [0001] The invention provides a circulator and a manufacturing method, which is a circulator applied to a linear motion bearing, embedded in the linear motion bearing, which can make the steel ball have a good circulation effect, greatly shorten the manufacturing process, reduce Equipment costs, increased production, etc. Background technique [0002] The manufacturing of circulators in the prior art is processed by forming tools, and a piece of metal is cut into the shape of the circulator. However, the cost of the tool is high and the process is cumbersome and time-consuming; another manufacturing method is lost-wax casting, but there are still Its inherent limitations include low good rate, difficulty in repairing burrs caused by the parting line, and labor-intensive problems; there is also a circulator that is plastic injection molded, but it is difficult to open the mold for the hollow part, making the mold It must be dismantled into several pieces, aff...
