Abstract
The utility model discloses an air intake flow guiding bend pipe consisting of two semicircular members riveted with each other via foldings respectively arranged on both sides of each of the two semicircular members. The extensibility of the steel plate is far superior to that of circular pipes so as not to cause cracking phenomenon by employing the processing method of stamping using thin steel plate and riveting upper and lower semicircle members after drawing; the bend pipe has excellent surface quality and good circularity; and the rate of finished products reaches 100% thereby reducing the production cost.
Description
Technical field: the utility model relates to a kind of bend pipe processing technique, relates in particular to the bend pipe processing technique of a kind of automobile with the air inlet honeycomb duct.
Technical background: in Modern Car,,, the air inlet honeycomb duct is housed generally in order to improve the inlet air conditions of motor because the space in the engine compartment is very nervous.Its main effect is: accelerate the flow velocity of air inlet, strengthen fuel gasification, to improve combustion process.The pipeline that general employing is long, thinner is to accelerate air velocity.Owing to the space reason in the engine compartment, the air inlet honeycomb duct is not a rectilinear duct, and therefore will inevitably use bend pipe comes connecting tube.This air inlet water conservancy diversion bend pipe is to adopt weldless tube to carry out bent tube technique to process at present, and material is easily wrapped up in the outer easy fragmentation in crook of this bent tube technique product, interior crook, in case the material phenomenon occurs wrapping up in the sectional area of gas-entered passageway is diminished, and causes air inlet to have some setbacks, easily produce noise.And tube bender must be import, and homemade tube bender is less than 70% the percentage of A-class goods, causes the cost of product to rise, and wastes very big.
The model utility content: the utility model purpose is to provide a kind of new structure air inlet water conservancy diversion bend pipe, adopt the book steel plate strike out two semicircle spares then riveted form, improved the surface quality of products and the percentage of A-class goods greatly.
The utility model is achieved in that a kind of air inlet water conservancy diversion bend pipe, form by two semicircle spares, it is characterized in that: in described semicircle spare both sides a stubborn limit is arranged respectively, in described another semicircle spare both sides a stubborn limit is arranged respectively also, two semicircle spares rivet together by stubborn limit.
The utility model compared with prior art has following advantage:
Since adopt the book steel plate carry out punching press, draw after the processing method of two semicircle spare riveteds up and down, the extensibility of steel plate is higher than pipe far away, therefore can not cause cracking phenomena; The surface quality of bend pipe is attractive in appearance, circularity good; Its percentage of A-class goods reaches 100%, has reduced production cost of products.
Description of drawings: accompanying drawing is the structural representation of bend pipe described in the utility model
1. the stubborn limit A 3. semicircle spare B of semicircle spare A 2. 4. stubborn limit B
Embodiment: from accompanying drawing as can be seen, a kind of air inlet water conservancy diversion bend pipe, form by semicircle spare A1 and semicircle spare B3, it is characterized in that: a stubborn limit A2 is respectively arranged in described semicircle spare A1 both sides, in described another semicircle spare B3 both sides a stubborn limit B4 is arranged respectively also, semicircle spare A1 and semicircle spare B3 rivet together by stubborn limit A2 and stubborn limit B4.
