Description
Technical field
The utility model belongs to hardware spare and accessory parts technical field, is exactly specifically to be related to a kind of cold-heading hair of lock core with movable plate
Base.
Background technology
It is usually used in security protection industry to arrive various hardwares as processing and installation, such as lock core band movable plate is exactly a kind of
Common hardware.Mode of the lock core with movable plate generally use cold-heading+punching press+machining, technological process are 1. blanking：
Using cold-heading disk member as raw material, using the automatical feeding system of equipment, auto-feed is automatic to cut；2. cold-heading：Using either simplex
Position cold header shaping disc flange；A 3. punching press：It is flat that bar portion bat is carried out using vertical hydraulic press；4. two times punch：
Bar portion cuboid and the shaping of afterbody chamfering are carried out using vertical hydraulic press；5. turning：By eccentric fixture, with machining mode
Eccentric small column on shaping disc.
The mode of this traditional cold-heading+punching press+machining there is processing mode it is backward, using equipment it is more,
Production process is more and production procedure is long, and workpiece needs multiple clamping on various devices, loses time, producing cost is high, consumes
The defects of manpower is more, labor intensity is high, low production efficiency, poor product quality stability.
Utility model content
The purpose of this utility model causes to produce aiming at the structure of cold heading blank of the above-mentioned existing lock core with movable plate
Efficiency is low, the technological deficiency of product quality stability difference.Lock core band movable plate described in a kind of cold heading blank of the lock core with movable plate is provided
Cold heading blank, the structure of cold heading blank of the existing lock core with movable plate is improved, reduces cold-heading hair of the lock core with movable plate
The manufacture difficulty of base improves product quality stability.
Technical solution
In order to realize above-mentioned technical purpose, the utility model designs a kind of cold heading blank of the lock core with movable plate, it includes cold
Upsetting blank body, it is characterised in that：The left end of the cold heading blank body is equipped with small column portion, the cold heading blank body and small
Disc flange portion is set between cylindrical portion, and the cold heading blank body is cuboid, the small column portion and the disc flange
Eccentric setting between portion.
Further, the small column portion is set with disc flange portion inscribe.
Further, the unilateral 45 ° of chamferings in the cold heading blank body right side.
Advantageous effect
Cold heading blank of a kind of lock core with movable plate provided by the utility model, has the advantages that：
1 meets the requirement for taking " metal cold extrusion (cold-heading) " technique；
2 improve the reinforcement of processing process control, simple and practicable, stable quality is reliable；
3 raising processing processes are simple, and equipment investment is few, production cost is low, consumption manpower is few, labor intensity is low, raw
Efficient, product quality is produced to stablize.
Description of the drawings
Attached drawing 1 is the front view of the utility model embodiment；
Attached drawing 2 is the top view of the utility model embodiment；
Attached drawing 3 is the left view of the utility model embodiment；
Attached drawing 4 is the right view of the utility model embodiment.
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 lock core with movable plate, it includes cold heading blank body 1, wherein, it is described
The left end of cold heading blank body 1 is equipped with small column portion 2, and disc flange is set between the cold heading blank body 1 and small column portion 2
Portion 3, the cold heading blank body 1 be cuboid, eccentric setting between the small column portion 2 and the disc flange portion 3.
The small column portion 2 is set with 3 inscribe of disc flange portion.
The unilateral 45 ° of chamferings in 1 right side of cold heading blank body.
The specific production process of cold heading blank of the above-mentioned lock core with movable plate 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 four stations on multistation cold-forming machine, carry out successively：Intense beam
Cuboid is molded, jumping-up progress head is preforming and section shaping, jumping-up clap the thickness of disc flange, shaping afterbody chamfering
With the eccentric small column on disk, the diameter of trimming for forming disc flange, by four cold-heading deformation processes, final production goes out lock
The cold heading blank of core ribbon movable plate.
(4) it is heat-treated：Since cold heading blank of the lock core with movable plate has manufactured whole shape and size, subsequently
Heat treatment process make its obtain than more uniform metallographic structure and the mechanical performance of stabilization.
(5) it is surface-treated：Assign Corrosion Protection of the lock core with the beautiful appearance of movable plate and certain specification.
Cold heading blank of a kind of lock core with movable plate provided by the utility model, has the advantages that：
(1) requirement for taking " metal cold extrusion (cold-heading) " technique is met；
(2) reinforcement of processing process control is improved, simple and practicable, stable quality is reliable；
(3) raising processing process is simple, equipment investment is few, production cost is low, consumption manpower is few, labor intensity is low,
Production efficiency is high, product quality is stablized.
Structure, ratio, size depicted in the present embodiment institute accompanying drawings etc., only to coordinate specification it is revealed in
Hold, so that those skilled in the art understands and reads, be not limited to the enforceable qualifications of the utility model, therefore not
Has technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are new not influencing this practicality
Under the effect of type can be generated and the purpose that can reach, it should all still fall and obtain and can contain in the revealed technology contents of the utility model
