Description
Technical field
The utility model belongs to hardware spare and accessory parts technical field, is specifically exactly to be related to a kind of special pipe nut cold-heading hair
Base.
Background technique
It is usually used in machinery industry to arrive various hardwares as processing and installation, such as fastener is exactly a kind of common
Hardware, be used a kind of mechanical when two or more parts or component to be fastenedly connected into an entirety
The general name of part.Nut is a kind of common fastener, and traditional nut is rectangular or six-sided nut, and structure is simple.It is complicated
Abnormity nut mostly use machining mode to complete, need by the processes such as turning, milling, drilling, bore hole complete, production efficiency
Low, utilization rate of raw materials is low, is not suitable for industrial mass production.
Utility model content
The purpose of this utility model is, production low aiming at above-mentioned existing nut manufacturing process chinese raw materials utilization rate
The technological deficiency of low efficiency provides a kind of special pipe nut cold heading blank, can cold-heading straight forming, the subsequent simple machine of need
Processing can be completed, high production efficiency, and utilization rate of raw materials is high, reduce production cost.
Technical solution
In order to achieve the above technical purposes, the utility model designs a kind of special pipe nut cold heading blank, it is characterised in that:
It includes special pipe nut cold heading blank ontology, and the special pipe nut cold heading blank ontology includes front and rear, before described
Flange flange is stretched out in the junction at portion and rear portion, and the front is hexagonal cylinder, and the rear portion is cylindrical body, the special pipe spiral shell
Female cold heading blank ontology is run through by three sections of stepped holes, and three sections of stepped holes include preceding hole, mesoporous and metapore, and the mesoporous is spiral shell
Pit.
Further, it is with plane where flange flange into the oblique of 15 ° of angles that the flange flange, which is located at the surface of front side,
Face.
Further, all with 10 ° of cone angle transition between the preceding hole and metapore and mesoporous.
Further, the preceding hole and the aperture of metapore are all bigger than mesoporous.
Beneficial effect
A kind of special pipe nut cold heading blank provided by the utility model, can cold-heading straight forming, subsequent need are simple
Machining can be completed, high production efficiency, utilization rate of raw materials is high, reduces production cost.
Detailed description of the invention
Attached drawing 1 is the main view of special pipe nut cold heading blank in the utility model.
Attached drawing 2 is the left view of special pipe nut cold heading blank in the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further.
Embodiment
As shown in figure 1 and 2, a kind of special pipe nut cold heading blank, it includes special pipe nut cold heading blank ontology 1,
The special pipe nut cold heading blank ontology 1 includes front 101 and rear portion 102, the junction of the front 101 and rear portion 102
Flange flange 103 is stretched out, the front 101 is hexagonal cylinder, and the rear portion 102 is cylindrical body, the special pipe nut cold-heading
Blank ontology 1 is run through by three sections of stepped holes, and three sections of stepped holes include preceding hole 104, mesoporous 105 and metapore 106, the mesoporous
105 be threaded hole.
It is with 103 place plane of flange flange into 15 ° of angles that the flange flange 103, which is located at the surface of 101 side of front,
Inclined-plane.
All with 10 ° of cone angle transition between the preceding hole 104 and metapore 106 and mesoporous 105.
The preceding hole 104 and the aperture of metapore 106 are all bigger than mesoporous 105.
A kind of special pipe nut cold heading blank provided by the embodiment of the utility model, can cold-heading straight forming, subsequent
Need to simply machine can be completed, high production efficiency, and utilization rate of raw materials is high, reduce production cost.
The present embodiment structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate specification revealed interior
Hold, so that those skilled in the art understands and reads, is not intended to limit the utility model enforceable qualifications, therefore not
Has technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are practical new not influencing this
Under the effect of type can be generated and the purpose that can reach, it should all still fall in the revealed technology contents of the utility model and obtain and can contain
In the range of lid.Meanwhile it is cited such as "upper", "lower", "left", "right", " centre ", " clockwise ", " inverse time in this specification
The term of needle " etc. is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, it is opposite to close
System is altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.
