Abstract

The invention discloses a kind of vehicle dormer window front beam processing method, comprise the steps: 1) blanking: according to the size of front beam of clerestory window, cutting metal flitch forms rectangle processing flitch; 2) blanking forming: first carry out twice bending, shaping two warp architectures; Then, at the crooked position of processing flitch, shear and form several arc notch; Finally, by die casting die cast; 3) deburring: the flitch of die cast is carried out deburring, obtains final products.The present invention can effectively enhance productivity, and reduces waste of material, thus reduces production cost.

Description

Vehicle dormer window front beam processing method

Technical field

The present invention relates to a kind of auto parts and components processing technology, particularly relate to a kind of vehicle dormer window front beam processing method.

Background technology

Vehicle dormer window is installed on roof, can effectively make car inner air flow, increases entering, for car owner brings health, comfortable enjoyment of fresh air.In the installation process in skylight, be connected with vehicle frame mainly through front beam, middle cross beam and guide rail.Existing front beam of clerestory window, in process, is placed on die casting mainly through opening greatly a metallic plate by one, then carries out die cast by mould, then carrying out deburring.But because front beam of clerestory window to have the warp architecture for bearing guide rail, therefore, in the process of die cast near two ends place, technological requirement is higher, in press bending process, easily cause other positions to damage, thus cause production qualification rate lower, production efficiency is also low.Meanwhile, be open metal blank greatly owing to adding what adopt man-hour, therefore also cause waste of material comparatively large, increase production cost.

Summary of the invention

For prior art above shortcomings, the object of the invention is to how to solve existing front beam of clerestory window processing technology requires high, qualification rate is low, production efficiency is low, and the problem that waste of material is large, a kind of vehicle dormer window front beam processing method is provided, can effectively enhances productivity, reduce waste of material, thus reduce production cost.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is such: a kind of vehicle dormer window front beam processing method, is characterized in that: comprise the steps:

1) blanking: according to the size of front beam of clerestory window, cutting metal flitch forms rectangle processing flitch, and the length and width of described processing flitch is greater than the length and width 10-20cm of front beam of clerestory window;

2) blanking forming: first carry out twice bending, shaping two warp architectures; Then, at the crooked position of processing flitch, shear and form several arc notch; Finally, by die casting die cast;

3) deburring: the flitch of die cast is carried out deburring, obtains final products.

Further, the degree of depth of described arc notch is less than 10cm.

Compared with prior art, tool of the present invention has the following advantages:

When 1, producing, first carry out flitch and cut out, thus waste of material can be made few, production cost is low.

2, first carry out twice bending, then carry out die cast, thus reduce technological requirement, and shear breach in knee, thus make die casting qualification rate high, and effectively improve product percent of pass and production efficiency.

Accompanying drawing explanation

Fig. 1 is process chart of the present invention.

Detailed description of the invention

Below in conjunction with drawings and Examples, the invention will be further described.

Embodiment: see Fig. 1, a kind of vehicle dormer window front beam processing method, comprises the steps:

1) blanking: according to the size of front beam of clerestory window, cutting metal flitch forms rectangle processing flitch, and the length and width of described processing flitch is greater than the length and width 10-20cm of front beam of clerestory window; The length of namely processing flitch is greater than front beam of clerestory window length 10-20cm; The width of processing flitch is greater than front beam of clerestory window width 10-20cm.

2) blanking forming: first carry out twice bending, shaping two warp architectures (bent into shape one warp architecture); Then, at the crooked position of processing flitch, shear and form several arc notch; Finally, by die casting die cast; Wherein, the degree of depth of described arc notch is less than 10cm; To ensure in press casting procedure, processing flitch can not cause damage by Yin Layan.

3) deburring: the flitch of die cast is carried out deburring, obtains final products.

Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
