Specific implementation mode
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
Electric bicycle integral type middle pipe as shown in Figs. 1-2, the middle pipe 1 are connected with 3 pipe 2 of cradle, the middle pipe 1
It is processed and is integrally formed by hydraulic way with 3 pipe 2 of cradle, 3 pipe 2 of the cradle is shaped in the lower end of middle pipe 1, middle pipe 1,
Both 3 pipes of cradle 2 are hollow;3 pipe 2 of the cradle at least has a flat side 20 to form the peace of cradle 3
Dress portion, the mounting portion include sedimentation plate 21, interface 22, and the sedimentation plate 21 is by the middle section of flat side 20 towards in pipe
Recess is formed, and the sedimentation plate 21 is equipped with the installation position for fixing cradle 3, and the setting of the interface 22 is in sedimentation plate 21
Centre is exposed for cradle 3.
Existing is generally to provide 3 mounting structure of cradle and middle pipe 1 to raw material by the different suppliers of two professions,
It is welded again through vehicle frame factory, welding procedure is complicated, and either manpower and material resources all need higher cost, and makes product appearance injustice
Suitable, everyone welds inconsistent, and quality is unstable, and production capacity is relatively low.Electric vehicle is filled by the way of hydraulic pressure processing after improving
3 pipe 2 of electric seat is integrally formed with middle pipe 1, and 3 mounting structure of cradle is formed on 3 pipe 2 of cradle, need not be welded, manpower
Material resources cost reduction, it is easy to use convenient for charging wire assembling and its function, no matter accessory factory and vehicle frame factory can all be promoted
Production capacity and quality increase vehicle frame security performance and prolong service life, and technique can improve aluminium alloy structure, it is made to have high rigidity,
High tenacity, resistance to compression, tension, and the features such as lightweight are easy to process to manufacture and environmental protection.
Preferably, be formed with attached mouth 220 at the edge of interface 22, a capping 30 via the attached mouth 220 with fill
Cradle 3 in 3 pipe 2 of electric seat is flexibly connected.Capping 30 can form cradle 3 and protect, while also reduce security risk, seal
Lid 30 generally uses silica gel material, one end to be in cradle 3 in attached mouth 220 and connect, and connection type can pass through shaft knot
Structure realizes rotation folding, and the characteristic that material can frequently be bent can also be utilized to realize folding.
In some embodiments, installation position is to be formed and settle at least two screw holes 221 on plate 21, will be filled using screw 31
Electric seat 3 is fixed on sedimentation plate 21, and mode of operation is simple, is easily realized.
In some embodiments, 3 pipe 2 of cradle is surround by four flat sides 20 and is formed, the junction of each flat side 20
For fillet.The wall thickness range of 3 pipe 2 of cradle is 2.2-3.5mm, and the rounded corner B radius values between each flat side are 2-
4mm, the rounded corner A radius values settled at plate peripheral edge are 5-7mm.The wall thickness of cradle 3 is used to ensure certain strong
Degree, and the value range of rounded corner ensures that the yield of processing, the product beyond the range are difficult to be molded.
Hydraulic pressure processing is as follows in the method for upper intermediate tube:
Pipe blanking, raw material drawing are cutting into pipe the dimensions of needs;
Epithelium saponification, in advance allotment lubricate Ji, water and lubrication Ji ratio 1:3 are allocated, and heat 80 ± 5 degrees Celsius,
Pipe fitting, which is put into wherein to impregnate 3 minutes, to be lifted, i.e., pipe fitting surfaces externally and internally has one layer of lubrication Ji surface layer, is extending convenient for workpiece, is elongating
Shi Buhui produces fracture and pulls inner surface;
Mandrel takes out pipe, being penetrated in pipe with tube drawing machine and mating shaft core after pipe fitting epithelium, changes pipe wall by stretching
Thickness is made well-balanced;
Annealing does T4 annealings using heat-treatment furnace, 500 degrees centigrade of temperature, and duration 4 hours is hard pipe fitting
Degree is lower, bend convenient for subsequent processing or beat tiltedly it is not broken, be unlikely to surface and pull;
The draw is beaten tiltedly with machine for shrinking after pipe fitting annealing, mainly changes the outer diameter perimeter size of pipe fitting different location, met
Pipe fitting appearance appearance the different materials needed;
Tempering, by process before, the characteristic of material will produce variation, need again at reusable heat processing furnace annealing
Reason, 500 degrees centigrade of temperature, 4 hours time, reduce reduce workpiece hardness, be equally prevent below process produce fracture
Or pull problem;
Epithelium saponification, with previous epithelium process operations mode and purpose all same;
Pre-shaped is made pre-shaped with the mode that hydraulic die is processed and is closer to finished product, is processed by pre-shaped and changes straight tube
External form, so that shape and shaping mould is matched;
Integer, using punching machine by it is preforming it is complete after product integer again, modification position and appearance structural adjustment extremely at
Type is close, and to facilitate formed product satisfy mould, such as rounded corner operates;
Hydro-forming, before all process steps finish after it is last use molding die hydro-forming again, control hydraulic pressure in molding
Pressure and the corresponding sliding block size of mold;
It cuts, extra both ends tailing excision, retains final ruler after molding on the product after hydro-forming is handled
It is very little;
CNC (Milling machine)Processing, after the completion of pipe fitting hydraulic pressure, with CNC processing pipe fitting cradles interface, installation position and opposite
Position, and remove extra rim charge;
Grinding and polishing, after processing is completed, by product surface, grinding wheel polishes CNC again, deburring, product examine, packaging shipment.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, the utility model can have various changes, combination and variation.It is all the utility model spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should be included in the utility model right it
It is interior.
