Problems solved by technology

The existing nest wire bobbins mainly include plastic bobbins and aluminum alloy bobbins according to different manufacturing materials. Plastic bobbins are characterized by easy manufacture and low cost, but their disadvantages are poor mechanical strength, low temperature resistance, and easy Aging, especially prone to breakage in the neck
The disadvantage of the aluminum alloy bobbin is that the surface is easy to oxidize, and the oxide layer will pollute the silk, which will cause the product to be scrapped
Therefore, recently, people use stainless steel materials to make nest wire bobbins. Due to the difficulty in forming stainless steel materials, welding methods are used, which is troublesome in processing, high in cost, and poor in surface finish.

Embodiment Construction

[0009] The invention discloses a processing mold and a processing method for a stainless steel nest wire bobbin. Its described processing mold such as figure 1 As shown, a mold cavity is formed in the mold, and a mold core is installed in the mold cavity. It is characterized in that the mold can be a section (integral mold) or a combined mold 2 divided into several sections, and the mold cavity is segmented. The cylindrical cavity 3 (diameter is equivalent to the size of the nest wire bobbin) and the expanded end cover cavity 4 (the diameter is equivalent to the size of the two ends of the nest wire bobbin) are composed of sections between each other, and the movable mold core 5 is installed in the cavity. , the movable mold core withdraws a section after making a section of molding, inserts the stainless steel tube 6 into the mold cavity between the mold 2 and the mold core 5, installs a seal 7 between the mold core and the stainless steel tube 6, and inserts a seal 7 at one ...

Abstract

A processing die of non-rust steel nest bobbin. The die formed by one or more sectional combination dies has a cavity where a core fit. Cavity is compounded with sectional drum cavity and bulge end cap cavity. Insert a non-rust steel pipe into cavity between die and core. Fit airtight packing between core and non-rust steel pipe. Solid plate is fit on one side of die. Jacked device is fit on outside of core. Fit tamper with topping-up hole in the cavity of one side of solid plate. Topping-up hole connects with fluid cylinder. Fill liquid in impression. Apply pressure to the non-rust steel pipe by fluid power. Make the end cap be expanded to form certain size. Divide the expanding part to obtain the product.

Description

technical field [0001] The invention relates to a processing mold for a stainless steel nest wire bobbin and a processing method for the product, belonging to the technology of textile accessories. Background technique [0002] In the process of weaving silk into silk cloth, the nest silk process is required, so the nest silk bobbin is used. The existing nest wire bobbins mainly include plastic bobbins and aluminum alloy bobbins according to different manufacturing materials. Plastic bobbins are characterized by easy manufacture and low cost, but their disadvantages are poor mechanical strength, low temperature resistance, and easy Aging, especially prone to breakage in the neck. The disadvantage of the aluminum alloy bobbin is that the surface is easy to oxidize, and the oxide layer will pollute the silk, which will cause the product to be scrapped. So recently people use stainless steel materials to make nest wire bobbins. Because stainless steel ...
