The purpose of this utility model is led aiming at the structure of the cold heading blank of above-mentioned existing spacer flanger face support tube
Cause low production efficiency, the technological deficiency of product quality stability difference.A kind of cold heading blank of spacer flanger face support tube is provided, it is right
The structure of the cold heading blank of existing spacer flanger face support tube is improved, and reduces the cold heading blank of spacer flanger face support tube
Manufacture difficulty, improve product quality stability.
Technical solution
Technical solution
In order to realize above-mentioned technical purpose, a kind of cold heading blank of spacer flanger face support tube of the utility model, it is wrapped
Include cold heading blank body, it is characterised in that：The cold heading blank body includes the cylinder portion one that left side is set, what right side was set
Cylinder portion two, the cylinder portion one and two junction of cylinder portion set disc flange, and the cold heading blank body is by
Heart through hole penetrates through, the left end orifice chamfer of the central through hole, the cold heading blank body left end chamfering.
Further, the left end orifice chamfer angle of the central through hole is 15 °.

1. satisfaction takes " metal cold extrusion (cold-heading) " technological requirement；
2. the process of processing is brief, controlled, stable quality is reliable；
3. processing, process is simple, and equipment investment is few, production cost is low, consumption manpower is few, labor intensity is low, production effect
Rate is high, stock utilization is high, product quality is stablized.
Description of the drawings
Attached drawing 1 is the structure diagram of the utility model embodiment.
Attached drawing 2 is the right view of the utility model embodiment.
Attached drawing 3 is enlarged drawing at A in attached drawing 1.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further,
Embodiment
As shown in attached drawing 1~3, a kind of cold heading blank of spacer flanger face support tube, it includes cold heading blank body 1,
It is characterized in that：The cold heading blank body 1 includes the cylinder portion 1 that left side is set, the cylinder portion two that right side is set
102, the cylinder portion 1 and 2 102 junction of cylinder portion set disc flange 103,1 quilt of cold heading blank body
Central through hole 104 penetrates through, the left end orifice chamfer of the central through hole 104, the 1 left end chamfering of cold heading blank body.
The left end orifice chamfer angle of the central through hole 104 is 15 °.
The 1 left end chamfer angle of cold heading blank body is 10 °.
The specific production process of the cold heading blank of above-mentioned spacer flanger face support tube is：
(1) pretreatment of raw material：Cold-heading is subjected to spheroidizing processing with steel alloy element coil material, obtains wire rod good
Plasticity.Then pickling, phosphatization, saponified surface processing are carried out, is allowed to the comparatively dense phosphatization of surface attachment last layer, saponification layer,
Its skin-friction coefficient is reduced, prevents occurring cold welding phenomenon during drawing or cold-heading molding.Then drawing process is carried out,
Steel wire rod on drawbench is carried out to the drawing of certain passage, obtains that surface is smooth, the smaller raw material steel wire rod of diameter deviation.
(2) cutting die：Cold-heading disk member is cut to the material section of certain length by the cutting system on cold-forming machine automatically,
Order feeding cold-forming machine.
(3) cold forming：By the continuously extruding and molding of six stations on multistation cold-forming machine, carry out successively：Upsetting
Thick shaping section and punching pre-determined bit, centre bore inner chamfer is preforming (straight hole), blank once inside out, backward extrusion deep-draw hole with
And centre bore inner chamfer shaping, the secondary overturning of blank continue deep-draw hole in centre bore chamfer mouth, jumping-up is molded disc flange face,
It finally perforates, by six cold-heading deformation processes, final production goes out blank (i.e. the cold heading blank of spacer flanger face support tube).
(4) it is surface-treated：Surface treatment is then to assign the beautiful appearance of spacer flanger face support tube and a set pattern
The Corrosion Protection of model.
A kind of cold heading blank of spacer flanger face support tube provided by the utility model, has the advantages that：
(1) meet and take " metal cold extrusion (cold-heading) " technological requirement；
(2) processing process is brief, controlled, stable quality is reliable；
(3) processing process is simple, and equipment investment is few, production cost is low, consumption manpower is few, labor intensity is low, production
