Abstract

The utility model relates to a kind of automobile exhaust effective major diameter w shape bending component and continuously shaped mould thereof, and described w shape bend pipe is docked by two w shape half round surfaces symmetrically and forms.Described mould comprises installs shaving die group in same die assembly and shaping mould group; Wherein, described shaving die group comprises the first trimming die head, the second trimming die head, the 3rd trimming die head and the 4th trimming die head successively; Described shaping mould group is ten shaping dies successively, and described each shaping die comprises w shape half round surface punch and corresponding w shape half round surface die respectively, and successively decreases in the gap between concave surface and punch.Therefore, the production technology of the utility model w shape bending component more simplifies, and employing the utility model mould can realize continuously, automatic assembly line is produced, and manufacturing efficiency is high, more energy-conserving and environment-protective, and product thickness is more even, and precision more high-performance is better.

Description

Automobile exhaust effective major diameter w shape bending component and continuously shaped mould thereof
Technical field:
The utility model relates to auto parts and components and processing technique field thereof, refers in particular to a kind of automobile exhaust effective major diameter w shape bending component and continuously shaped mould thereof.
Background technique:
Existing major diameter bend pipe adopts the mode of high temperature forging to manufacture usually, and this mode of production operation is loaded down with trivial details, and energy ezpenditure is large, and product uniformity compares and is difficult to control, and affects quality of product.Also the employing sectional pipe had is welded, and this mode needs to cut straight tube, causes very large waste.
Model utility content:
The purpose of this utility model is the above-mentioned deficiency overcoming existing nut plate processing technique, provides a kind of automobile exhaust effective major diameter w shape bending component and continuously shaped mould thereof.
The utility model realizes the technological scheme that its object adopts: a kind of automobile exhaust effective major diameter w shape bending component, and described w shape bend pipe is docked by two w shape half round surfaces symmetrically and forms.
A continuously shaped mould for automobile exhaust effective major diameter w shape bending component, it comprises installs shaving die group in same die assembly and shaping mould group; Wherein, described shaving die group comprises the first trimming die head, the second trimming die head, the 3rd trimming die head and the 4th trimming die head successively; Described shaping mould group comprises single forming die head, secondary forming die head, three shaping dies, four shaping dies, five shaping dies, six shaping dies, seven shaping dies, eight shaping dies, nine shaping dies, ten shaping dies successively, described each shaping die comprises w shape half round surface punch and corresponding w shape half round surface die respectively, and successively decreases in the gap between concave surface and punch.
Therefore, the production technology of the utility model w shape bending component more simplifies, and employing the utility model mould can realize continuously, automatic assembly line is produced, and manufacturing efficiency is high, more energy-conserving and environment-protective, and product thickness is more even, and precision more high-performance is better.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model mould middle and lower part convex portions;
Fig. 2 is the structural representation of the utility model mould middle and upper part female mold part.
Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As Figure 1-Figure 2, described in the utility model is a kind of automobile exhaust effective major diameter w shape bending component, and described w shape bend pipe is docked by two w shape half round surfaces symmetrically and forms.
The utility model automobile exhaust effective major diameter w shape bending component is by following mould-forming: continuously shaped mould comprises installs shaving die group 2 in same die assembly and shaping mould group 3, wherein, described shaving die group comprises the first trimming die head 21, second trimming die head 22, the 3rd trimming die head 23 and the 4th trimming die head 24 successively, removed by clout between the corner of tabular supplied materials and adjacent material section by shaving die group 2, the final continuous print that formed is as the approximate w shape plane of w shape semicircle Doubly curved surfaces, described shaping mould group 3 comprises single forming die head 301 successively, secondary forming die head 302, three shaping dies 303, four shaping dies 304, five shaping dies 305, six shaping dies 306, seven shaping dies 307, eight shaping dies 308, nine shaping dies 309, ten shaping dies 310, described each shaping die comprises w shape half round surface punch 31 and corresponding w shape half round surface die 32 respectively, and successively decrease in the gap between die and punch, successively through ten punching presses, stretch, make supplied materials evenly thinning, become curved and fill up the sizing space preset between die and punch, form w shape half round surface, every two w shape half round surfaces can complete the making of w shape bend pipe by the mode of welding.
Therefore, the production technology of the utility model w shape bending component more simplifies, and employing the utility model mould can realize continuously, automatic assembly line is produced, and manufacturing efficiency is high, more energy-conserving and environment-protective, and product thickness is more even, and precision more high-performance is better.
