Abstract
Branch gear die is passed the present invention relates to a kind of bicycle, including Shang Chong, middle mould and undershoot, middle mould uses hollow structure, upper punching and undershoot are connected in middle mould, upper punching be provided with cone pinion between undershoot, upper punching is fastened on upper outer rush in accessory by upper friction plate and lower friction plate, upper outer rush is provided with Shang Erchong in accessory, upper two punching in upper punching by extending to cone pinion, and following two punch is set in undershoot, and plug is arranged with following two punch.The bicycle biography branch gear die surface gone out using mould punching is smooth, and unique outlook is attractive in appearance, and the machining accuracy of mould is high, cost-effective without carrying out secondary operation to hand-held tool ratchet head.
Description
Technical field
The present invention relates to a kind of mould, and in particular to a kind of bicycle passes branch gear die.
Background technology
It is the parts applied on bicycle to pass branch gear, and existing biography branch Gear Production mode is both needed to after shaping again
Secondary operation is carried out, and rough surface is unsightly, and this greatly have impact on the production efficiency for passing branch gear, and secondary operation
When, precision is low, and error is big, also increases production cost.
The content of the invention
Present invention seek to address that drawbacks described above there is provided one kind without secondary operation, surface is smooth, and appearance looks elegant is voluntarily
Car passes branch gear die.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems is：
A kind of bicycle passes branch gear die, including Shang Chong, middle mould and undershoot, and upper punching and undershoot are connected in middle mould, upper punching and undershoot
Between be provided with cone pinion, upper punching by upper friction plate and lower friction plate be fastened on it is upper it is outer rush in accessory, upper outer rush in accessory sets
Shang Erchong is equipped with, upper two punching in upper punching by extending to cone pinion, and following two punch is set in undershoot, and core is arranged with following two punch
Rod.
In the preferred embodiment of the present invention, it is raised that plug periphery is provided with a circle.
In the preferred embodiment of the present invention, the upper outer accessory that rushes outer rushed accessory one and upper outer rushes two groups of accessory by upper
Into.
The beneficial effects of the invention are as follows：Mutually traditional production technology than before, the bicycle gone out using mould punching passes branch
Gear die surface is smooth, and unique outlook is attractive in appearance, and the machining accuracy of mould is high, without carrying out secondary add to hand-held tool ratchet head
Work, it is cost-effective, and due to the raising of machining accuracy, material needed for reduction process indirectly saves raw material.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the sectional view of the present invention.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
A kind of bicycle as depicted in figs. 1 and 2 passes branch gear die, including upper punching 1, middle mould 2 and undershoot 3,1 He of upper punching
Undershoot 2 is connected in middle mould 3, and cone pinion 4 is provided between upper punching 1 and undershoot 2, and upper punching 1 passes through upper friction plate 8 and lower friction plate
Card 7 be fastened on it is outer rush in accessory, it is upper it is outer rush accessory include again it is upper it is outer rush accessory 1 and it is upper it is outer rush accessory 26, upper outer rush is matched somebody with somebody
Two punchings 9 are provided with part, upper two punching 9 in upper punching 1 by extending to cone pinion 4, and following two punch 10 is set in undershoot 3, under
Plug 5 is arranged with two punchings 10.It is raised that the periphery of plug 5 is provided with a circle.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
