Description
Technical field
It is a kind of through hole sleeve metal parts invention production technology long the present invention relates to machining technology field.
Background technology
As shown in Figure 1, Figure 2, through hole sleeve metal parts long is now widely used in the brake line of automobile, motorcycle industry
In hydraulic flexible pipe joint in.
Through hole sleeve metal parts production long, is primarily now two kinds of processing modes：
First, it is machined, product (see Fig. 1) is shaped by the complete machining of virgin metal raw material.
2nd, the cutting technology of half cold-heading half, with wire rod through multistage cold former cold-heading into semi-finished product (see Fig. 2), then
Carry out being cut into shaped article.
Both are processed as widely used processing method now, but it is high to suffer from machining working hour expense, waste of material
It is many, precision defect not high.
The content of the invention
It is an object of the invention to provide a kind of through hole sleeve metal parts invention production technology long, production work of the invention
Skill is entirely to employ the creative invention being concentrated use in of several multi-station cold-heading molding technologies, fully achieves this through hole
Sleeve metal parts long without machining.
The technical scheme is that：
A kind of through hole sleeve metal parts cold upsetting production technique long, comprises the following steps：
Step 1) blanking：Make cylinder blank；
Step 2) shaping：Cylinder blank is squeezed out into fillet by the first cold upsetting die of car；
Step 3) squeeze bar upsetting ball：Cylinder blank with rounded corners is put into the second cold upsetting die of car and is extruded, squeezed out
The thinner connecting rod of diameter, and the upsetting spherical shoulder being relatively large in diameter, two ends are squeezed out in head cavity hole and afterbody with rushing rod respectively
Lumen pore；Going out head lumen orifice from-inner-to-outer includes central lumen hole, terraced steps hole and rim of a cup stepped hole；
Step 4) squeezing bushing shaping：Step 3 is obtained into workpiece it is put into the 3rd cold upsetting die of car to be extruded, upsetting is spherical
Shoulder presses are deformed into cylindrical shoulder；By rim of a cup stepped hole crimp cup-shaped pipe sleeve；
Step 5) counterbore：Step 3 is obtained into workpiece it is put into the 4th cold upsetting die of car to be extruded, is increased in afterbody with rod is rushed
The depth of lumen pore；
Step 6) extruding tubule sleeve forming：Step 5 is obtained into workpiece it is put into the 5th cold upsetting die of car to be extruded, by diameter
Thinner connecting rod is squeezed into hollow bush, and only remaining centre is a bit of has no through；
Step 7) squeezing through-hole：Step 6 is obtained into workpiece it is put into the 6th cold upsetting die of car to enter eleven punch 11, gets through tubule set,
What is had no through partially changes into waste material discharge, obtains the lumen therethrough after punching.
The step 1) to step 7) include the operation of the unnecessary extruded stock punching removal for producing squeezing action.
The beneficial effects of the invention are as follows：
Production technology of the invention, whole process is to deform shaping Technology design with the cold-heading of multistation metal, has used cold
Highest forming technique means in upsetting technology, it is determined that a whole set of correct production of this metal parts metal fluid modification becomes
Shape mode and completion size.
The super extruding puncturing technique for wherein completing, is that common process for machining is impossible.Mach extruding
The limit of perforation is that aperture ratio is no more than 4 times, and aperture ratio reaches 12-14 times in present invention process.And realize this metal
The technique of part continuous production and processing on multistage cold former.
Cold upsetting production technique of the invention, makes the production of through hole sleeve metal parts long can be with：
1st, high-volume efficiently production, reaches one second product；
2nd, more than 50% raw material are saved；
3rd, improve precision, the precision of existing machining in positive and negative 0.2mm or so, using cold upsetting production work of the invention
Skill machining accuracy can be within 0.05mm, and precision improves 4 times.
