Abstract
The utility model discloses an air outlet end cone for an automobile engine, which is an integral structure part formed by stamping a plate and comprises a cone-shaped shell on which a ventage is formed eccentrically. The utility model has the advantages that: waste gas can be smoothly exhausted and can be purified uniformly; high flow resistance and a large amount of accumulated water can be avoided; the air outlet end cone for the automobile engine has high rigidity and long service life and is convenient to operate; and tool accuracy is ensured.
Description
Technical field
The utility model relates to a kind of auto parts, particularly a kind of outlet side awl that is used for motor car engine.
Background technique
The outlet side awl is a kind of part of car exhaust gas purifier output terminal, is the link that connects between purifier and offgas duct.Play the effect of guiding waste gas output.It is characterized by funneling cone, leak is in the side of funnel cone, is a kind of cone structure part of the non-regular profile that is formed by the sheet metal deep drawn.
Former outlet side part is the plane funnel, and leak is at the center of funnel, and when its defective one was the waste gas discharge, being prone to gives vent to anger freely was not obstructed, and influences power; The 2nd, the ponding of outlet pipe is difficult to discharge, and easily causes the corrosion of purifier shell, shortens the life-span.
The model utility content
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of outlet side awl that is used for motor car engine unimpeded, that ponding is easy to discharge of giving vent to anger is provided.
The purpose of this utility model is achieved in that a kind of outlet side awl that is used for motor car engine, is an integral structure component that is processed by plate stamping, comprises a conical shell, and off-centre is provided with a leak on conical shell.
Described leak is the funnel shape round mouth of convergent.
The outlet side awl that is used for motor car engine of the present utility model is owing to be the integral structure component that is processed by plate stamping, and its end face is a cone, and leak is side-lower, has quickened the circulation of waste gas, has reduced the resistance of discharging, the unimpeded discharge of waste gas.Cone-shaped design, when waste gas was discharged, ponding also flowed out thereupon, and dry all the time no ponding has reduced the corrosion of ponding to cone in the purifier chamber, has prolonged the life-span of part.
Description of drawings
Fig. 1 is the perspective view that the utility model is used for the outlet side awl of motor car engine.
Embodiment
Referring to Fig. 1, the outlet side awl that is used for motor car engine of the present utility model is an integral structure component that is processed by plate stamping, comprises a conical shell 1, and off-centre is provided with a leak 11 on conical shell 1.This leak is the funnel shape round mouth of convergent.
The making method that is used for the outlet side awl of motor car engine of the present utility model is, by crucial road prefaces such as blanking, stretching, shaping, side flanging, punching, flange, form the cone of how much non-regular profiles, from the geometric type cavity improve gas smooth/resistance and chamber in seeping phenomenon.
The crucial road preface processing method that bore the outlet side that is used for motor car engine of the present utility model is as follows:
Stretch: with Y100T (master cylinder pressure: 12 ± 1Mpa pressure of taking blame for others: 3 ± 1Mpa) and drawing-die tool 1009385-KL-20, formation arch type shape, H=43 ± 0.5.
Shaping: (master cylinder pressure: 12 ± 1Mpa pressure of taking blame for others: 3 ± 1Mpa) hydraulic presses and sizing die 1009385-KL-30 are organized into the convex cone with Y100T.
The side deburring: with J150T press machine and repair side mould 1009385-KL-40, the unnecessary sideline judge after the shaping is gone, the form accuracy of part is controlled at ￠ 126.9 ± 0.3, burr≤0.2.
Punching: with J80T press and piercing die 1009385-KL-60, center hole ￠ 39 ± 0.1 burrs≤0.2 of punching out oblique cone end, workpiece surface does not have the plucking cut.
Hole flanging: with Y100T (master cylinder pressure: 12 ± 1Mpa) and plunging die 1009385-KL-60, rout up the limit of the port of beveled cone, the control part precision is ￠ 55 ± 0.2, T 〉=1.4.
Compared with prior art, the air outlet end cone for automobile engine of the present utility model have waste gas unimpeded, purify evenly, be difficult for producing big flow resistance and ponding, rigidity is strong, the advantages such as long service life. And easy to operate, frock guarantees precision.
Claims (2)
