2021 New Style Stamped Sheet Metal Parts - Flange, Exhaust Manifold, No.1 – Meiln

Part Name: FLANGE, EXHAUST MANIFOLD, NO.1

Material Grade: SPH270C-OD

Short/Brief description

Flange, exhaust manifold connect part

 Material Size:  2.60mm x 323mm x 95mm

Process: X8 Stage 800T TRF

Cavity: one part out

Complexity: High

◆Application: The part applicated to automotive exhaust manifold connect part

Press Machine: 2000T hydraulic press, 1200T Mechanical

Inspection Tool: Checking fixture, CMM, Laser arm scan

Lead Time: 4 months 

◆Part Quality Concern: Extremely high requirement for x4 burr holes because it is very important for sealing performance with connecting exhaust manifold port.

Background:

This part is produced by 8 stages process, 1^st draw,2^nd draw, 3th trim, 4^th trim,5^th bend, 6^th cam trim, 7^th cam trim and 8^th separate-cam trim. As we can see, there are four holes in the part which is for manifold port to connect. The inlet flange surface is designed with a whole convex surface that is higher than the inlet flange surface, the airway hole is distributed on the convex surface, and the flange is connected with the cylinder head through the convex surface. Because the whole convex surface is the same shape to the whole concave surface, thus the whole convex surface and concave surface can be stamped in the same time, which is convenient for processing and manufacturing, and the edge of the flange body is also provided with flanging, not only can increase the structural strength of the flange body, but also can be welded bracket or fitted other parts in the flange edge.

For the four burr holes, its burr height is quite strict requirement for our customer, however our process provided a good result to this part, which final part shown a good quality with these four holes for its tolerance.

Advantage:  

Our company have much experience with exhaust manifold parts and its connecting parts like flange parts, also with forming simulation, good process and processing technology for these parts from professional designers.
