Air and Exhaust manage The resulting clinched joints are ein referred to as joints in the following. Previous issues VW This electronically generated standard is authentic and valid without signature.

The English translation is believed to be accurate. In case of discrepancies the German version shall govern. No part of this document may be transmitted or reproduced without prior permission of a Standards Department of the Volkswagen Group.

Parties to ein contract can only obtain this standard via the B2B supplier platform www. Clinching allows for joining of both similar and different materials. It is also possible to join surfacetreated parts zinc-coated, aluminized, organically coated, 85935. For 8593- on the assessment of round clinched joints without cutting element, see PV It is the joining of at least two overlapping sheet metal, tube or profile parts achieved by means of cold deformation with punch and die.

The connection is a positive locking and friction locking joint. Metallic continuity may occur under certain conditions.

Considerably lower strength is to be expected if this is not the case. For sheets with different plasticity characteristics, the harder sheet is to be arranged on the side of the punch wherever possible “hard in soft”. The overall thickness of the joining partners must not exceed 5 mm. There are no generally applicable values for the base thickness tb. The nominal and tolerance values must be determined for each individual case. With segmented dies, the microsections must be located in the center of the die segments.

Especially for round joints, care must be taken that the joint does not fall apart when preparing the microsections. This can be achieved by bonding or by slightly offsetting the microsection location out of the joint center. In the latter case, the microsection must be prepared so that the microsection plane is located in the center of the clinched joint for the determination of 85935- geometric characteristics.

Their properties must match to the cases to be tested. Here, it must be ensured that the measured values cin not affected by the preparation work. Specimen width is 45 mm, overlap of the sheets is 35 mm and length of the single sheets is at least mm. Rectangular joints are to be located perpendicular to the load direction. At least 10 specimens are required for the release tests. The minimum break force Fmin depends on the sheet thickness combination, the dn of the raw material and the type of joint and must be specified in the drawing.

The result Fmin Ftransverse — 2 sigma is a reference value for the drawing specification. Release testing process qualification A total of 10 specimens according to Section 3. Table 5 — Abbreviations FLS Measured lap-shear force of the individual specimens [kN] Mean value of the measured lap-shear forces [kN] Fmin Minimum value of the lap-shear force according to drawing [kN] As rough values e.

Here, at least the ratios specified in Table 6 must be achieved: The flange height is 35 mm Aalternatively 16 mm B.

It must be ensured that the joints are not stressed when the sheets are bent e. The assessment criteria according to Section 3. General information — — Part no.

Drawing version desired values of the joint: The joints must be carried out such that window bonding material can be pressed into the recess created by the joining process, see Figure 4.

If the base is cracked, check for microsection preparation errors. If this is not the case, the joint is NOK.
