Description
Technical field
The present invention relates to a kind of techniques to be suitable for high-volume more particularly, to a kind of rear connecting bushing processing technology
It manufactures, it belongs to automobile parts and manufactures field.
Background technique
Currently, automobile parts in order to obtain higher-strength and preferable productivity effect, using cold extrusion and are machined phase
In conjunction with process manufacture, anisotropic due to product shape, the technical process needed is also not quite similar.
Publication date is on 06 20th, 2017, in the Chinese patent of Publication No. 106862868A, discloses a kind of title
For the patent of invention of " a kind of automobile bushing production technology ".The patent includes the following steps: that steel plate is cut by (1) plate shearing machine
Circular steel plate；(2) it stretches: circular steel plate obtained by step (1) being carried out three times with the different stretching die of draw ratio and hydraulic device
It stretches, obtains cylindrical member with flange；(3) punching: the cylinder with flange obtained by piercing die and hydraulic device blanking process (2)
The cylinder bottom of shape part；(4) shaping trimming: shaping is carried out to the resulting part of step 3 with shaping shaving die, and flange is punched
To the size to suit the requirements；(5) after the completion of step (4), sharpener along lining pipe body upper part cut out first slope after cut out again
Second slope；(6) polishing machine sanding and polishing is carried out to the product that step (5) obtains；(7) product surface that step (6) is obtained
It is painted using flush coater.Although the patent be able to solve existing flanging process on the corner exist stress concentrate, it is cracked
Problem, but it is not suitable for rear connecting bushing processing technology, machining process and effect are also different.
Therefore it provides a kind of technological design advantages of simple, easy to operate, the rear connecting bushing processing of high production efficiency
Technique, 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 a kind of technological design is provided and is simply closed
Reason, product size are stablized, easy to operate, the rear connecting bushing processing technology of high production efficiency.
Technical solution used by the present invention solves the above problems is: a kind of rear connecting bushing processing technology,
It is characterized in that: including the following steps:
(1) blanking: raw material are wire rod, 35 diameter blanking of φ；
(2) shaping: material jumping-up shaping, being shaped into φ 55.7 by φ 35 is to stretch hole process to prepare；
(3) stretch hole: specific punch die structure, backward extrusion shaping blank, inside and outside concentricity reach within φ 0.2, outer diameter φ 56；
(4) Vehicle Processing: overall dimensions are processed；
(5) punching: being punched out bottom irregularly-shaped hole, and mold is fixed using special die carrier, and punching fracture belt is smooth；
(6) it drills；Drilling and milling center drilling；
(7) it saws angle: special fixture being equipped with using circular sawing machine, carries out sawing angle.
Preferably, in the step (1) of the present invention, using cold headers blanking.
Preferably, being processed in step (4) of the present invention using numerically controlled lathe.
Preferably, punching uses precision punching in step (5) of the present invention.
Preferably, carrying out sawing angle using high-speed steel circular saw blade in step (7) of the present invention.
Compared with prior art, the present invention having the following advantages that and effect: integrated artistic is mature, and product size is stablized, warp
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 bushing of different sizes；Technique combination cold extrusion and machining, advantages of simple, technique mistake
Journey is that blanking → shaping → stretches hole → Vehicle Processing → punching → drilling → saw angle.
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 rear connecting bushing processing technology includes the following steps:
(1) blanking: raw material are wire rod, and 35 diameter of φ is suitable for cold headers blanking；High production efficiency.
(2) shaping: material jumping-up shaping, being shaped into φ 55.7 by φ 35 is to stretch hole process to prepare.
(3) stretch hole: specific punch die structure, backward extrusion shaping blank, finished goods such as cup-shaped are inside and outside same due to preamble shaping
Axis degree can achieve within φ 0.2, and the outer diameter φ 56(process deflection is larger, to lathe tonnage demand 500T or more).
(4) Vehicle Processing: numerically controlled lathe processes overall dimensions.
(5) punching: product keypoint part is bottom irregularly-shaped hole, therefore the process uses precision punching, and mold is using dedicated
Mould bases is fixed, and punching fracture belt is smooth.
(6) it drills；Drilling and milling center drilling, need to be equipped with respective bore fixture, to improve production efficiency.
(7) it saws angle: special fixture, high-speed steel circular saw blade sawing angle is equipped with using circular sawing machine.
Equipment and processing method involved in the present embodiment are as follows: 1, cold headers, hydraulic press, punching machine, annealing furnace, phospholeum,
Shot-blasting machine, numerically controlled lathe, drilling and milling center, circular sawing machine；2, cold extrusion, soft annealing, phosphorus saponification lubrication, numerical control programming.
The present embodiment carries out soft annealing processing by cold headers blanking, shaping, to material, when deflection is larger, need pair
Otherwise product softening can press motionless, mold damage etc., ball blast removal annealing residual, clean surface, so that phospholeum film fills
Dividing covering, stretch punch die and adjust up and down, guarantees that concentricity equidimension requires, machining uses the product clamping turning of internal expanding fixture,
Punching die forward direction punching, product are inserted in punch-pin punching, and drilling design corresponds to multiple groups clamping tooling, saw angle because of angle angle,
And have correspondingly-sized relationship with end face aperture, special fixtures clamping need to be designed, operative employee is by aperture and clamp locating pin to formal dress
Folder carries out sawing operation, considers the abrasion sawing face of saw blade there are burr, postorder removes flash removed with vibro-grinding technique.
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
