Abstract
The present invention proposes that a kind of one-shot forming manufactures the new technology of cover of sewing machine shuttle peg, it is characterised in that：After metal dust is mixed with binding agent, inject in the closing die cavity of injection machine, complete feeding procedure, through product design, Design of Dies, after Making mold, the injection moulding Jing after injection machine, bobbin case blank is obtained, the binding agent in workpiece, as skimming processes is then chemically removed, Jing high temperature sinterings are processed again, process after needing to carry out after the completion of sintering, quality inspection finally obtains finished product.By process above, it can make bobbin case once-forming, it is not necessary to machine, and not produce chip, and raw material can be reused, and utilization rate reaches 100%, and labor and material saving, low cost high financial profit, its new technology have originality.
Description
Technical field
The present invention relates to the processing and forming field of complicated shape and difficult-to-machine material, particularly a kind of new technology of one-shot forming manufacture cover of sewing machine shuttle peg.
Technical background
Cover of sewing machine shuttle peg has adopted decades, production technology is also never to change in decades, each product will be through cutting out more than 60 procedures such as material, cold-heading, punching press, grinding, drawing, brill, welding, and production efficiency is extremely low, the typical labor-intensive processing technology of category.
The content of the invention
The present invention proposes that a kind of one-shot forming manufactures the new technology of cover of sewing machine shuttle peg, it is characterised in that：After metal dust is mixed with binding agent, inject in the closing die cavity of injection machine, complete feeding procedure, through product design, Design of Dies, after Making mold, the injection moulding Jing after injection machine, bobbin case blank is obtained, the binding agent in workpiece, as skimming processes is then chemically removed, Jing high temperature sinterings are processed again, process after needing to carry out after the completion of sintering, quality inspection finally obtains finished product.
By process above, it can make bobbin case once-forming, it is not necessary to machine, and not produce chip, and raw material can be reused, and utilization rate reaches 100%, and labor and material saving, low cost high financial profit, its new technology have originality.
Description of the drawings
Figure is present invention process flow chart.
Specific embodiment
As illustrated, present invention process flow process is：
1 produces granular feedstock, produces after the metal dust for choosing is well mixed with binding agent.
2 feedings, on injection machine close injection raw material injection in die cavity.
3 Making molds, a product design b Design of Dies.
4 injection mouldings, after Mold Making, load injection machine the peg or spindle mold for designing, and Jing injection machine injection mouldings obtain bobbin case blank.
5 degreasings, chemically process injection moulding blank, remove the binding agent in workpiece.
6 sintering, then the process of Jing high temperature sinterings, obtain densification bobbin case part.
7 finally obtain bobbin case manufactured goods, process, quality inspection after also needing to carry out for the portioned product that sintering is completed.
