In order to solve the above technical problem, the present invention provides following technical solutions: a kind of chassis ellipse welded tube part adds
Work method, it is characterised in that: processed using cold headers, comprising the following steps: S1, cut tool for wire rod with cold headers
It is cut into the length of needs, the product after being cut；S2, the both ends of product are suppressed into deep hole respectively with the mold of Cold header
And location hole, the deep hole and location hole are ellipticity；S3, it will be punched between deep hole and location hole and reject the useless of generation
Material.
Further, which further includes S4, the product that S3 step is formed is put into flexible mould, and product is located at
The end face of location hole processes to form solder joint, while outer chamfer in shaped article both ends.
Further, flexible mould is equipped with solder joint end tooth ejector sleeve, and solder joint passes through solder joint end tooth ejector sleeve extrusion forming.
Further, in step s 2, pilot hole is first suppressed, using overturning and being moved to other stations, pilot hole is deepened to squeeze
It is pressed into deep hole.
Further, deep hole is formed by secondary extrusion, and it is 45mm that deep hole squeezes depth for the first time, and squeeze makes depth for the second time
Reach 85.6mm.
Further, in step s 2, further include positioning nose end production fillet, production fillet and compacting pilot hole simultaneously into
Row.
Further, positioning hole length is 4.8mm.
Further, conversion and overturning of the product between different step station are completed by manipulator.
Further, step S1 further comprises the straightening-wheel alignment for first passing through cold headers, then is sent to S1 by drawing-inroller
Place station.
Further, size needed for the preceding preforming size of station and welding spot forming station are calculated before processing.
Beneficial effects of the present invention:
The present invention successfully passes the extrusion molding to anisotropic part, and realizing exit orifice in welded tube part is all elliptical mesh
's；Guarantee additionally by the preforming size of station and welding spot forming station die before calculating solder joint turgor and
Size requirement.The primary property forming on cold headers of this technique, need to only pass through one procedure of cold-heading, so that production efficiency improves height,
And effectively reduce fabrication error.

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 chassis ellipse welded tube part, it is characterised in that: utilizes
Cold headers are processed, comprising the following steps:
Step 1: referring to Figures 1 and 2, wire rod is straightened by the straightening-wheels of cold headers, drawing-inroller transmission, with mold by line
Material is cut to required length, such as Fig. 1
Step 2: referring to Fig. 3 and Fig. 4, the wire rod having been turned off is transmitted by the manipulator of cold headers, is existed by mold manufacture
Upper end processing pilot hole and the chamfering for being machined with circumferencial direction in the other end simultaneously.
Step 3: referring to figure 5 and figure 6, the product that step 2 obtains is overturn by manipulator, and pilot hole end is downward.
Step 4: referring to Fig. 7 and Fig. 8, this station is passed over the product translation of a upper process by manipulator, and then one
End squeezes pilot hole and deepens to squeeze out location hole at the deep hole of 45mm depth, the other end, and location hole and deep hole are ellipticity.
Step 5: referring to Fig. 9 and Figure 10, continued for product to be moved to next station by manipulator, by the depth of 45mm depth
Hole secondary extrusion to depth is 85.6mm, and the other end will then position hole forming to 4.8mm.
Step 6: 1 and Figure 12 referring to Fig.1 does rotary movement by manipulator, then rejects product orientation by drawing light to rush stick
Waste material between hole and deep hole makes product orientation hole and deep hole be formed through ellipticity inner hole.
Step 7: 3 and Figure 14 referring to Fig.1 does rotary movement by manipulator, and the product of a upper station is put into Figure 15 activity
In mold, solder joint is shaped by end tooth ejector sleeve 1.Guarantee the high and interior outer chamfer of the turgor to solder joint, tooth using flexible mould
Size reach product size requirement.
Further, to guarantee that product through-hole is ellipticity, before calculating before processing the preforming size of station and solder joint at
Size needed for shape station, to guarantee turgor and the size requirement of solder joint.In addition, other than main molding die, material
Folder, cut-off-die, drawing-inroller, draws material wheel etc. and all designs according to the geomery of product scissors, makes embryo material of the product since most
State can successfully extrusion forming step by step, guarantee the stability of production.
The present invention is by the careful design to die size, the design of blank wire size, the design of related spare and accessory parts, with
And prejudging to metal forming flowing breaches so that realizing makes processing and manufacturing of the oval shaped piece on cold headers
The limitation of butt-welding pipe fitting geomery promotes the diversification of chassis part.This technique primary property forming, production on cold headers
It is high-efficient, and effectively reduce fabrication error.
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.
