The present invention provides a kind of processing method of the automobile shock flat recess with tooth pipe, this method is processed by cold headers, comprising the following steps: wire rod S1, is cut to required length with blank mold, obtains the product with first end face and second end face；S2, deep hole is suppressed in first end face and suppresses shallow bore hole in second end face；S3, it punches deep hole and deep hole to form a through-hole；S4, both ends of the surface knob；S5, first end face and second end face pressed key groove.Straight tube by the once-forming both ends of the surface of cold-heading with tooth, inner hole both ends with keyway, saves manufacturing procedure, improves production efficiency, reduce manufacturing cost, improves the market competitive power of enterprise.
Description
Technical field
The present invention relates to the process for machining and manufacturing of automobile shock part, specially a kind of automobile shock flat recess band tooth pipe
Processing method.
Background technique
At present in the damping straight tube product of automobile, with tooth product using more and more common, and end face band tooth is interior for end face
Hole both ends band keyway is fewer and fewer.The keyway processing of machined part is processed by milling or broaching layout, and for both
There is the automobile damping pipe fitting with tooth form with slot, conventional machining mode is first to mill product cold upset forming again at present
Processing is cut, manufacturing procedure is twice, to spend the time long, influence production efficiency.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and proposing one kind only needs one procedure of cold headers to be added
The automobile shock flat recess of work is with the processing method of tooth pipe.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of 1. automobile shock flat recess bands
The processing method of tooth pipe, it is characterised in that: processed using cold headers, comprising the following steps: S1, with blank mold by wire rod
It is cut to required length, obtains the product with first end face and second end face；S2, first end face suppress deep hole and
Second end face suppresses shallow bore hole；S3, it punches deep hole and deep hole to form a through-hole；S4, both ends of the surface knob；S5, first end face and
Biend pressed key groove.
Further, step S2 further comprises first in first end face and second end face compacting location hole.
Further, in step S2, the location hole of the location hole reprocessing second end face of first end face is first processed.
Further, process first end face location hole while processing second end face compacting have circumferencial direction it is outer fall
Angle has the outer chamfer of circumferencial direction in first end face compacting while processing second end face location hole.
Further, it suppresses and re-compacted second end face after workpiece is spun upside down by manipulator after the location hole of first end face
Location hole.
Further, step S1 further comprises first passing through straightening-wheel to be straightened wire rod.
Further, the keyway is flat recess.
Further, step S3 further comprises spinning upside down product first with manipulator.
Beneficial effects of the present invention:
1, processing method of the automobile shock flat recess with tooth pipe that the present invention announces, only by one procedure of cold-heading, directly
It connects and processes tooth form and flat recess in identical product, solve and cold-heading and Milling Process two procedures is needed to add in background technique
The problem of work automobile damping inner tube product, production efficiency is improved, manufacturing cost is reduced, improves the market competition of enterprise
Power.
2, in order to process both ends keyway, using knob after first punching, then keyway technique is squeezed, both avoided workpiece in mold
Processing makes to generate positional shift, while avoiding stress from concentrating and influencing the service life of mold
3, before suppressing deep hole and shallow bore hole, bull nose first is suppressed in first end face and second end face, eliminates extra end
Face burr guarantees mold Reducing distortion resistance when shaping flat recess, and achievees the purpose that improve die life.

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 pipe passes through cold-heading
Machine is processed, comprising the following steps:
Step 1: referring to Fig.1, spiral material is straightened by straightening-wheel, drawing-inroller transmission, needed for being cut to wire rod with mold
The length wanted, it is second end face B that product top, which is the lower end first end face A, at this time；
Step 2: referring to Fig. 2, the wire rod having been turned off is transmitted by manipulator, is sent to next station, is produced first end face
There are location hole and second end face to have the product of circumferencial direction outer chamfer.
Step 3: referring to Fig. 3, product is spun upside down by manipulator, in second end face processing location hole simultaneously in first end
Face processes outer chamfer
Step 4: referring to Fig. 4, this station squeezes out deep hole in product upper end, that is, second end face.To guarantee that product is got through subsequent
Bore area is smooth when inner hole, squeezes out shallow bore hole in first end face.
Step 5: referring to Fig. 5, spinning upside down workpiece again using manipulator, then punch deep hole and shallow bore hole to form one newly
Inner hole, and reject the waste material of generation.First is that product structure needs, another effect is that product is concrete-cored in hole in both ends knob
Stick guarantees that the position of product in a mold is stablized.
Step 6: referring to figure 6 and figure 7, in product first end face and second end face knob, while by the outer chamfer of both ends of the surface
It is expressed to the size of product requirement.The mold of this station is equipped with movable mold core, it is therefore an objective to reduce the friction of product periphery and mold
Power makes the upper and lower tooth form uniform force of product, produces the high tooth proportions of identical tooth.Movable mold such as Figure 10, movable mold are equipped with bullet
Spring 1 and movable mold core 2.
Step 7: referring to Fig. 8 and Fig. 9, both ends band will be produced in this station with tooth product translation using manipulator
The finished product of keyway.In the present embodiment, the keyway is flat recess, and in other embodiments, keyway can be according to actual production need
It asks and is adjusted to other shapes.
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.
