Description
Technical field
The present invention relates to automotive seat formation of tubes processing technique field, be specially the crowded teeth mould of pipe fittings of automobile seat headrest.
Background technology
A kind of pipe fittings of automobile seat headrest, it is U-shaped pipe fitting, in the inner side of one side pipe wall, has continuous tooth mouth, and one of them vertical teeth mouth 33 tooth depth reaches 3.8mm, tube wall and tooth plane coupling part thickness can not be less than 0.3mm, adopt common flute profile mould to process this dark profile of tooth, because pipe fitting tube wall is thinner, its material extends, be not enough to meet the forming requirements of tube wall and tooth plane, therefore be prone to collapse angle and tube wall of pipe face and bore a hole with the fracture of tooth plane junction, thereby can not reach processing request; And the whole pressurized of crowded teeth moulding rear tubular member is prone to pipe fitting to the vertical direction bulging distortion of punching press, need to use other shaping mould to carry out shaping processing again, and working (machining) efficiency is low.
Summary of the invention
For the problems referred to above, the invention provides the crowded teeth mould of pipe fittings of automobile seat headrest, it can solve and adopt existing common flute profile mould to process dark tooth easily to produce that pipe face subsides, the problem of flute profile perforation, and can effectively improve working (machining) efficiency.
