Abstract

The utility model discloses a built -in battery bottom plate of electric scooter mould that bends, including last mould, lower mould, fusiformis plug, ejector pin, it forms the ascending die cavity that bends to one side to go up between mould, the lower mould, during the fusiformis plug can bend from slant upside dip nozzle material, the ejector pin is ejecting with the fusiformis plug in expecting from the opposite side dip nozzle. The utility model relates to a special built -in fusiformis plug is placed before the type pipe bends in the intraductal bended -arc department of type, after the type pipe bends, utilizes fusiformis plug cambered surface motion plastic type tube -surface, increases the roughness of surface.

Description

Segway Human Transporter internal battery base plate bending die

Technical field

The utility model belongs to metal pipe material processing technique field, and in particular to Segway Human Transporter internal battery base plate bends Mould.

Background technology

Electric return board car bottom plate is because needing internal battery, and interior die cavity is big（Such as Fig. 1）, but the processing of existing electric return board car bottom plate To there is backplate surface in mould concavo-convex in press-bending processing, makes difficult, had both affected product appearance, affect again battery etc. other internal zero The installation of part, pole needs novel bending processing mold.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Segway Human Transporter internal battery base plate Bending die, low cost, while the quick cooling of aluminium alloy can be realized.

It is that, up to this purpose, the utility model is employed the following technical solutions：

A kind of Segway Human Transporter internal battery base plate bending die, including upper die and lower die, fusiformis plug, push rod；On described Press-bending die cavity obliquely is formed between mould, lower mould, during the fusiformis plug can be stretched at materials in the tube press-bending from oblique upside, institute State push rod to stretch into the ejection of fusiformis plug in materials in the tube from opposite side.

Preferably, the fusiformis plug includes fusiformis head and the rod portion being connected with fusiformis head, and fusiformis plug is placed in Rod portion is oblique with the upper die and lower die parallel above after materials in the tube.

Preferably, the fusiformis head upper surface, lower surface are cambered surface and upper cambered surface angle is less than lower camber side.

Preferably, the push rod includes ejection part and bar portion, and ejection part front end is provided with a triangular cut, is in arc at unfilled corner Face transition.

Preferably, the push rod is connected with hydraulic oil cylinder driving ejection.

Beneficial effect：The Segway Human Transporter internal battery base plate bending die that the utility model is provided, is to improve large-scale lumen The phenomenon of concave-convex surface after bent into shape, the built-in fusiformis plug of design specialized is positioned in type pipe at curved arc before type pipe bends, After type pipe bends, using fusiformis plug cambered surface motion shaping type pipe surface, increase the flatness of outer surface.

Specific embodiment

The technical solution of the utility model is further illustrated below by the drawings and specific embodiments.

Embodiment 1：Segway Human Transporter internal battery base plate bending die as shown in Figure 5, including upper mould 1, lower mould 2, fusiformis Plug, push rod；Press-bending die cavity obliquely is formed between upper mould 1, lower mould 2, fusiformis plug includes fusiformis head 31 and and shuttle Connected rod portion 32 of forming head portion 31, the upper surface of fusiformis head 31, lower surface are cambered surface and upper cambered surface angle is less than lower camber side, shuttle It is oblique parallel above with upper mould 1, lower mould 2 that shape plug is placed in rod portion 32 after materials in the tube 4；Push rod includes ejection part 21 and bar portion 22, top Go out the front end of portion 21 and be provided with a triangular cut, be in cambered surface transition at unfilled corner；Fusiformis plug can stretch into materials in the tube 4 and press from oblique upside In crook, push rod is connected with hydraulic oil cylinder driving and stretches into the ejection of fusiformis plug in materials in the tube 4 from opposite side.

Use process of the present utility model is as follows：

1. pipe fitting is intercepted；

2. in hydraulic pressure press-bending die cavity materials in the tube being put between upper mould 1, lower mould 2, such as Fig. 2；

3. fusiformis plug is put into into materials in the tube internal pressure crook, such as Fig. 3；

4. go up mould 1 to push, press-bending materials in the tube, such as Fig. 4；

5. hydraulic oil cylinder driving push rod ejects arc plug, such as Fig. 5；

6. push rod is exited, mould is opened, press bending process is completed.

Applicant states that 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, will change in specific embodiments and applications, this specification content Should not be construed as to restriction of the present utility model.
