Ji high efficiency；It can satisfy product size requirement, product size tolerance internal control 0.2mm；With versatility, by mold, journey
The adjustment of sequence can process a series of crash bar bracket of different sizes；Technique combines hot forging, cold extrusion and machining, simply
Technical process: blanking → shaping → is hot-forged → stretches hole → preforming waist hole → punching → Vehicle Processing → chamfering.
Detailed description of the invention
Fig. 1 is the process flow diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited to following embodiments.
Embodiment.
Referring to Fig. 1, the present embodiment crash bar bracket processing technology includes the following steps:
(1) blanking: raw material are wire rod, and 25.6 diameter of φ is suitable for cold headers blanking；High production efficiency.
(2) shaping: jumping-up shaping is shaped into φ 34 by φ 25.6 in two times and prepares for hot forging process.
(3) it is hot-forged: to shaping blank heating to 850~900 DEG C, being squeezed cylinder blank using 160T hot forging press machine
For special-shaped blank (blank and cavity plate gap influence hot forging sequence molding, and adjusting is bad, will appear angle of collapsing, burr).
(4) stretch hole: finished product structure designs specific punch die structure, backward extrusion shaping blank, and upper/lower die centering is adjusted, hole pair
Title degree can achieve 0.1, which uses 250T press machine.
(5) preforming waist hole: the secondary hole of straightening one's back based on macropore, position degree control within 0.2, and base thickness will control
Within 2.5mm, which uses 250T press machine.
(6) punching: going defective material process, which uses 63T press machine.
(7) Vehicle Processing: numerically controlled lathe machines both ends of the surface.
(8) chamfering: chamfering is carried out to the punching fracture belt of waist hole site residues, removes flash removed, meets size requirement.
The present embodiment is related to following equipment: 1, cold headers, hydraulic press, punching machine, annealing furnace, phospholeum, shot-blasting machine, numerical control lathe
Bed, instrument lathe；2, cold extrusion, hot forging, soft annealing, phosphorus saponification lubrication, numerical control programming.
The present embodiment by cold headers blanking, (process can be cancelled under the premise of increasing raw material diameter, i.e., for shaping
Major diameter raw material are purchased directly to be hot-forged), material hardens after hot forging, to material carry out soft annealing processing, deflection compared with
When big, product need to be softened, otherwise can press motionless, mold damage etc., ball blast removal annealing remains, clean surface, so that
Phospholeum film sufficiently covers, and stretches punch die and adjusts up and down, guarantees the requirement of symmetry equidimension, and preforming waist hole guarantees waist hole position
Degree requires, and punching uses back flush mode, and it is accurate that positioning facilitates, and machining uses structural clamp product vehicle similar to product shape
It cuts, to ensure firm grip, chamfering can not can then be processed with lathe in machining by instrument lathe due to being kidney slot,
It designs grips product and carries out chamfering.
By above-mentioned elaboration, those skilled in the art can implement.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different, and above content is only to structure of the invention example explanation described in this specification.It is all according to
According to equivalence changes or simple change that the invention patent design structure, feature and principle is done, it is included in this hair
In the protection scope of bright patent.Those skilled in the art can do described specific embodiment various
The mode that the modify or supplement or adopt of various kinds is similar substitutes, and without departing from structure of the invention or surmounts present claims
Range defined in book, is within the scope of protection of the invention.
