CN205926719U - Scooter bottom plate pipe bending mandrel rod assembly - Google Patents

Abstract

The utility model discloses a scooter bottom plate pipe bending mandrel rod assembly, with the curved pipe wheel mould cooperation work that is fixed with the return bend bottom plate, including two return bend plugs, plug fixing base, drive arrangement, it is just right that two return bend plugs are fixed on the plug fixing base with return bend bottom plate both sides die cavity, and the return bend plug leads to turn the corner pipe slider and moves on the plug fixing base, and plug slider and drive arrangement link to each other and drive the return bend plug and move. The utility model discloses cross oil cylinder drive plug back -and -forth movement and adjust pipe bending mandrel length of bar degree to get and take the pipe material, setting up the fixed return bend plug of plug fixing base, having improved return bend plug stability, it is easier to operate.

Description

Scooter bottom plate bend pipe mandrel component

Technical field

The utility model belongs to metal pipe material processing and manufacturing with equipment manufacturing technology field and in particular to scooter bottom plate is curved Tube core rod assembly.

Background technology

Scooter bottom plate is generally irregular cavity pipe, as shown in figure 1, for adapting to scooter configuration design needs, need to be to different Type pipe carries out bend pipe process.Because both sides die cavity is less than normal in existing process, problem on deformation easily occurs at bend pipe A, as Fig. 2 institute Show；Simultaneously because bend pipe plug length partially can not be processed, two plug positioning inconvenience, the reason such as operating difficulties, existing process equipment Typically no install bend pipe plug additional, both sides die cavity Tube Bending Deformation takes shaping processing after bend pipe, and re-shaping exercise amount is big.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of scooter bottom plate bend pipe plug group Part, it is ensured that bend pipe is indeformable, reduces re-shaping exercise.

For reaching this purpose, the utility model employs the following technical solutions：

A kind of scooter bottom plate bend pipe mandrel component, and the bend wheel mould cooperating being fixed with bend pipe base plate, including two Individual bend pipe plug, plug fixed seat, driving means, two bend pipe plugs be fixed in plug fixed seat with bend pipe base plate both sides type Chamber is just right, and bend pipe plug is moved in plug fixed seat by bend pipe slide block, and plug slide block is connected with driving means and drives bend pipe Plug moves.

Preferably, described driving means include oil cylinder, bar, and oil cylinder is connected with described bend pipe slide block by connecting rod.

Preferably, two bend pipe plugs are setting up and down in described plug fixed seat.

Beneficial effect：The scooter bottom plate bend pipe mandrel component that the utility model provides, before and after hydraulic oil cylinder driving plug Mobile regulation bend pipe plug length, to fetch materials in the tube；Setting plug fixed seat fixed bending tube plug, improves bend pipe plug steady Qualitative, operation is easier；Built-in plug bend pipe design is cooperatively formed using said structure and irregular cavity pipe, materials in the tube are indeformable, Reduce the shaping process after bend pipe.

Brief description

Fig. 1 is the structural representation of irregular cavity pipe；

Fig. 2 is irregular cavity pipe structural representation after bending；

Fig. 3 is structural representation of the present utility model；

Fig. 4 is the structural representation of processing connection procedure.

Specific embodiment

To further illustrate the technical solution of the utility model below by the drawings and specific embodiments.

Embodiment 1：Scooter bottom plate bend pipe mandrel component as shown in Figure 3, fixes including two bend pipe plugs 1, plugs Seat 2, connecting rod 4, oil cylinder 5, bend pipe plug 1 is fixed in plug fixed seat 2, plug fixed seat 2 is arranged on bend wheel mould 3 attached Closely, reduce the distance between bend pipe plug 1 and bend wheel mould 3, specifically can be defined using length by bend pipe base plate 6；Bend pipe plug 1 Just right with bend pipe base plate both sides die cavity, bend pipe plug 1 is moved in plug fixed seat 2 by bend pipe slide block, and plug slide block passes through Connecting rod 4 is docked with oil cylinder 5.

As shown in figure 4, bend pipe base plate 6 is inserted in bend pipe plug 1 when using, carry out bend pipe operation.

Applicant states, above content is only preferred embodiment of the present utility model, for the ordinary skill people of this area Member, according to thought of the present utility model, all will change, this specification content in specific embodiments and applications Should not be construed as to restriction of the present utility model.
