Abstract
The present invention provides a kind of processing method of the automobile shock flat recess with tooth flanged pipe, this method is processed by cold headers, the following steps are included: S1, with blank mold wire rod is cut to required length, the product with first end face and second end face is obtained；S2, shallow bore hole is suppressed in first end face；S3, deep hole is suppressed in second end face；S4, it processes to form tooth form and flat recess in second end face；S5, waste material will be punched and rejected between pilot hole and deep hole, form a stepped hole.Only by one procedure of cold-heading, processing is generated a variety of abnormally-structured directly on identical product, is solved the problems, such as that cold-heading and machining two procedures is needed to process automobile damping inner tube product in background technique, is improved production efficiency.
Description
Technical field
The present invention relates to the process for machining and manufacturing of automobile shock part, specially automobile shock flat recess band tooth flanged pipe
Processing method.
Background technique
The damping inner tube product of automobile at present, majority are all that inner hole is special-shaped or end face is with tooth or one word of end face band
Slot.And three kinds of shapes occur then greatly increasing difficulty of processing simultaneously on a product simultaneously, since structure is complicated, to realize
Each shape, usually using cold-heading and machining two procedures.Because process is more, homogeneity of product is relatively poor, simultaneous processing
The time is longer.For machining milling flat recess, a product needs about 3 points of process time from clamping, milling, discharging
Clock also needs deburring 1 minute after processing, and milling flat recess either simplex sequence just needs 4 minutes, largely effects on production efficiency.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, propose it is a kind of using only need one procedure of cold headers into
Processing method of the automobile shock flat recess with tooth flanged pipe of row processing.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of automobile shock flat recess band tooth
The processing method of flanged pipe, it is characterised in that: processed using cold headers, comprising the following steps: S1, with blank mold by line
Material is cut to required length, obtains the product with first end face and second end face；S2, shallow bore hole is suppressed in first end face；
S3, deep hole is suppressed in second end face；S4, it processes to form tooth form and flat recess in second end face；S5, it will be beaten between shallow bore hole and deep hole
Waste material is worn and rejected, a stepped hole is formed.
Further, step S2 further include: first suppress pilot hole in first end face, shallow bore hole is generated with compacting pilot hole is crossed.
Further, in step S2, bull nose is suppressed in second end face while suppressing pilot hole.
Further, pass through re-compacted shallow bore hole out after manipulator overturning product after compacting pilot hole.
Further, step S1 further comprises first being straightened wire rod by straightening-wheel.
Further, step S3 includes that product is first formed a boss again from second end face close to the head overstriking of second end face
Suppress deep hole.
Further, concave surface is made in the rear and front end of boss while step S3 forms boss.
Beneficial effects of the present invention:
1, processing method of the automobile shock flat recess with tooth flanged pipe that the present invention announces only passes through one of work of cold-heading
Sequence, processing generates a variety of abnormally-structured directly on identical product, solves and needs cold-heading and machining twice in the prior art
Process improves production efficiency come the problem of processing automobile damping inner tube product.
2, it is designed by the preform to preceding station in diameter and the proportion of deformation of height, so that contrate tooth profile is full, it will
The overstriking of product head forms boss, prevents excessive deformation ratio from causing material cracks and forming in product shaping flange unstable
It is fixed, achieve the purpose that improve die life.
3, it carries out step S2 to include compacting first end face pilot hole and suppress bull nose in second end face, removes extra end face
Burr.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution: a kind of processing method of the automobile shock flat recess with tooth flanged pipe, special
Sign is: being processed using cold headers, comprising the following steps:
Step 1: referring to Fig.1, wire rod is straightened by straightening-wheel and is transmitted by drawing-inroller, is cut off wire rod with blank mold
For required length, workpiece has the first end face and underlying second end face being located above at this time.
Step 2: referring to Fig. 2, the wire rod having been turned off is transmitted by manipulator, is sent in this station die, as shown in figure 8,
Used first perforating mold has upper die and lower die, upper mold insertion pin 1., while being 2. equipped with corresponding pin rushing stick
Groove, to guarantee to rush stick 2. in the unique positions relationship of circumferencial direction.By the squeezing action of upper and lower mould, manufacture is gone to work
The pilot hole and workpiece second end face of part first end face have the outer chamfer of circumferencial direction, to remove extra end face burr.
Step 3: referring to Fig. 3, the product of previous step is overturn by manipulator and is moved in the second perforating mold, the
Shallow bore hole is processed on the basis of the pilot hole of one end face, downward, as shown in figure 9, under the action of upper mold, product is whole for first end face at this time
Elongation extends downwardly.In order to guarantee the alignment of preceding station and this station pilot hole, here 3. the lower die of mold devises key,
Using bottom four hole seats 4. on process keyway, four hole seats are rushed stick with abnormity further through flat position mode and are 5. cooperated so that
5. special-shaped punch die stablizes cooperation without generating rotation with lower die position, realize that product will not generate rotation in a circumferential direction.
The mold setting of this step can also be applied to subsequent step, promote the stability of product processing.
Step 4: referring to Fig. 4, this station is by product head preform, so that the top outer diameter of product increases, to form one convex
Platform prevents excessive deformation ratio from causing material cracks and forming in product shaping flange unstable.Refering to fig. 10, this station
Mold processes concave surface C in the front and rear sides of boss, and two sides concave surface front and back is symmetrical, and a word of end face of flange is shaped for postorder station
Slot reserves the space of metal flow.
Step 5: referring to Fig. 5, in the second end face extrusion deep hole of product.
Step 6: referring to Fig. 6, continuing pressing component and shape flange, process to form tooth form and flat recess in second end face.
Step 7: referring to Fig. 7, by product pilot hole and stretching hole and punch, produce required inner bore of step.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, other any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present invention,
It should be equivalent substitute mode, be included within the scope of the present invention.
