Abstract
The utility model discloses an upsetting valve rod nut. The upsetting valve rod nut is characterized in that the upsetting valve rod nut is made of a wire material in an upsetting manner, the excircle of the valve rod nut is composed of an upper cylindrical body, an outer hexagonal cylinder body, a middle cylindrical body and a lower cylindrical body which are arranged in an upper-down; the outer diameter of the upper cylindrical body is minimal, the outer diameter of the lower cylindrical body is maximal, and the size of the peak of an opposite angle of an outer hexagonal cylinder body is equal to the outer diameter of the middle cylindrical body; and an inner hole of the valve rod nut is composed of upper and lower column holes, the inner diameter of the upper column hole is small, and the inner diameter of the lower column hole is large. The upsetting valve rod nut provided by the utility model has the advantages that the design is reasonable, the upsetting process is convenient, the material is saved, and the cost is low.
Description
Technical field
The utility model relates to a kind of Stem Mut.
Background technique
Stem Mut is for the sealing of valve rod, and its structure relative complex, machining accuracy are relatively high, if adopt machining, although can process required complex appearance, processing cost is high, and waste of material is large; If adopt upsetting method processing processed, because the design outline that is subject to Stem Mut is limit, usually can only upsetting go out the simpler profile of two sections or three sections, also to be aided with machining, and require material property high, so cost is also higher.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of upsetting system processing of being convenient to reasonable in design, saves material, the upsetting that cost is low Stem Mut processed.
The utility model is implemented by the following technical programs:
A kind of upsetting Stem Mut processed, it is characterized in that: by metal wire rod upsetting system, formed, the cylindrical of Stem Mut is comprised of upper cylindrical body setting up and down, outer-hexagonal cylinder, mediate cylindrical and lower cylindrical body, upper cylindrical external diameter minimum, lower cylindrical external diameter maximum, the outer-hexagonal cylinder the angular vertex size is equaled to the external diameter of mediate cylindrical, the endoporus of Stem Mut is comprised of upper and lower cylindrical hole, the internal diameter of upper cylindrical hole is little, and the internal diameter of lower cylindrical hole is large.Upsetting Stem Mut processed is selected the middle-carbon steel metal wire rod material of spheroidizing.
The Stem Mut reasonable in design of technique scheme, the material of employing is the middle-carbon steel metal wire rod material through spheroidizing, not only be convenient to the processing of upsetting system, and directly type is made in upsetting, does not need other machining, saves material, cost is low.
The accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
The left view that Fig. 2 is Fig. 1.
Embodiment
Describe details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, upsetting of the present utility model Stem Mut processed, by metal wire rod upsetting system, formed, the selection of material is the middle-carbon steel metal wire rod material through spheroidizing, the cylindrical of Stem Mut is comprised of upper cylindrical body 1 setting up and down, outer-hexagonal cylinder 2, mediate cylindrical 3 and lower cylindrical body 4, the external diameter minimum of upper cylindrical body 1, the external diameter maximum of lower cylindrical body 4, outer-hexagonal cylinder 2 the angular vertex size is equaled to the external diameter of mediate cylindrical 3, the endoporus of Stem Mut is comprised of upper cylindrical hole 5 and lower cylindrical hole 6, the internal diameter of upper cylindrical hole 5 is little, and the internal diameter of lower cylindrical hole 6 is large.
Stem Mut of the present utility model, reasonable in design, the material of employing is the middle-carbon steel metal wire rod material through spheroidizing, and directly type is made in upsetting, does not need other machining, and the cost of material is low in saving.
