Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further,
Embodiment
As shown in attached drawing 1~4, a kind of cold heading blank of adjusting bolt, it includes cold heading blank body 1, wherein, it is described cold
Upsetting blank body 1 includes the hexagonal prisms portion 101 in left side, and the left end in cylinder portion 1 is connected with the hexagonal prisms portion 101, circle
The right end of trunk portion 1 is connected with the left end in cylinder portion 2 103, the cylinder portion 1 and cylinder portion 2 103
Junction is chamfering step 104, and the periphery in the cylinder portion 2 103 is equipped with arc groove 1 and arc groove 2 106.
The right end surface chamfer in the cylinder portion 2 103.
There is bolt sign 101a on 101 left side of hexagonal prisms portion.
104 angle of chamfering step of 2 103 junction of the cylinder portion 1 and cylinder portion is unilateral 30 °.
The right side chamfer angle in the cylinder portion 2 103 is unilateral 45 °.
The bolt sign 101a is protrusion font.
The specific production process of the cold heading blank of above-mentioned adjusting bolt 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-heading molding：By the continuously extruding and molding of four stations on multistation cold-forming machine, carry out successively：
Tube reducing shaping round bar, the preforming draft bulb of heading, jumping-up carry out sign on the preforming socket cap in head and head, cut
Edge forming turret head, the V-groove on extrusion forming cylindrical bar, by four cold-heading deformation processes, final production goes out adjusting bolt
Cold heading blank.
(4) it is heat-treated：Due to the cold heading blank of adjusting bolt) whole shape and size have been manufactured, so
Subsequent heat treatment process purpose is it is made to obtain than more uniform metallographic structure and the mechanical performance of stabilization.
(5) it is surface-treated：Surface treatment is then to assign the anti-corrosion of the beautiful appearance of adjusting bolt and certain specification
Corrosion energy.
