Description
Technical field
The present invention relates to a kind of techniques to belong to automobile chassis structures zero more particularly, to a kind of counterweight ironware processing technology
Component is suitable for producing manufacture in enormous quantities, it belongs to automobile parts and manufactures field.
Background technique
Currently, automobile chassis structures need each position connection structure of framework, including turns to, presses down shake, load-bearing, therefore for closing
The spare and accessory parts comprehensive performance at key position is more demanding, the structure spare and accessory parts of Highlander's automobile chassis, higher in order to obtain in production
Intensity and preferable productivity effect are manufactured using cold extrusion with the process that combines of machining, due to product outside
The opposite sex of type, the technical process needed are also not quite similar.
Publication date is on 07 10th, 2013, in the Chinese patent of Publication No. 101979889B, discloses a kind of title
For the patent of invention of " a kind of processing method of bushing ".The processing method of the bushing of the patent, by copper-based clad steel band
Implement the following steps: 1) blanking；2) hasp is rushed；3) U shape is rushed；4) full circle；5) finishing circle；6) cylindrical grinding；7) boring
Inner circle, it is characterised in that: the step 5) finishing circle, step 6) cylindrical grinding, step 7) boring inner circle are squeezed by a procedure
Pressure is completed, to form surface roughness and wall thickness required for bushing；Although the processing method has good economy, work
Skill performance, work on the spot environment are greatly improved, but are not suitable for counterweight ironware processing technology.
Therefore it provides a kind of simple process is reasonable, product size is stablized, and the mechanical property of material is good, high production efficiency
Counterweight ironware processing technology, it appears particularly necessary.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide a kind of combination cold extrusion and machine
Tool processing, simple process is reasonable, and product size is stablized, high production efficiency, the counterweight ironware processing technology with versatility.
Technical solution used by the present invention solves the above problems is: the counterweight ironware processing technology, it is characterised in that: step
It is rapid as follows:
(1) blanking: according to the suitable raw material of drawing size selection, blanking is carried out；
(2) shaping: material jumping-up shaping is prepared to stretch Kong Xu；
(3) stretch hole: specific punch die structure, forward extrusion shaping blank meet size requirement；
(4) punching: specific punch die structure, punching press inner hole penetrate through its bottom；
(5) machine: blank end face Vehicle Processing after punching carries out overall length to end face and base thickness is processed.
Preferably, in the step (1) of the present invention, raw material are the wire rod of φ 28.5mm.
Preferably, in the step (1) of the present invention, using cold headers blanking.
Preferably, in step (2) of the present invention, material jumping-up shaping is shaped into φ 45.5mm by φ 28.5mm.
Preferably, due to preamble shaping, inside and outside concentricity reaches within φ 0.3mm in step (3) of the present invention,
46.5 ± 0.3mm of outer diameter φ, 37 ± 0.1mm of internal diameter φ.
Preferably, Vehicle Processing uses the product clamping turning of instrument collet in step (4) of the present invention.
Preferably, the cutter of Vehicle Processing passes through reconditioning after Vehicle Processing using welding knife in step (5) of the present invention
Process fillet and chamfering.
Compared with prior art, the present invention having the following advantages that and effect: integrated artistic advantages of simple, maturation, product ruler
Very little stabilization, high financial profit；It can satisfy product size requirement, product size tolerance internal control 0.2mm；By to mold, program
Adjustment can process the sleeve cold-extruded parts of different sizes a series of.
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, a kind of counterweight ironware processing technology of more economicalization of the present embodiment, the technique combination cold extrusion and mechanical
Processing, simple process process: blanking, stretches hole, punching and Vehicle Processing at continuous shaping.
(1) blanking: raw material are wire rod, and 28.5 diameter of φ is suitable for cold headers blanking (advantage high production efficiency).
(2) shaping: material jumping-up shaping, being shaped into φ 45.5 by φ 28.5 is to stretch Kong Xu to prepare.
(3) stretch hole: specific punch die structure, forward extrusion shaping blank, the following Fig. 1 of finished goods are inside and outside same due to preamble shaping
Axis degree can achieve within φ 0.3, outer diameter φ 46.5 ± 0.3, internal diameter φ 37 ± 0.1.
(4) punching: specific punch die structure, punching press inner hole penetrate through its bottom.
(5) machine: blank end face Vehicle Processing after punching carries out overall length to end face and base thickness is processed.
Equipment and processing method involved in the present embodiment are as follows: (1) cold headers, punching machine, annealing furnace, phospholeum, shot-blasting machine,
Instrument lathe；(2) cold extrusion, soft annealing, phosphorus saponification lubrication, frock clamp.
Specific embodiment in this example are as follows: cold headers blanking, continuous shaping is carried out to it, and (shaping must not have outer wall folding
It is folded, depending on shaping state in two times to multiple shaping), ball blast removal annealing residual, clean surface, so that phospholeum film sufficiently covers
Lid is stretched punch die and is adjusted up and down, guarantees that the requirement of concentricity equidimension, punching form it into tubulose, pier drum type forward extrusion blank at
