Clinching Process

1.Positioning& Press-in: At this step , first make sure the punch is reset to the top dead center ,put the lower sheet in flatly , then stack the upper sheet on the lower sheet , also pay attention to aligning the riveted area with the center of the mold.

2.Forming: Early forming stage: Press-in elastic stage, stretch forming stage. Initial press-in elastic stage: from the moment the punch contacts the upper sheet to the moment the upper and lower sheets begin to bend plastically.

3.Plastic deformation: During the clinching filling stage , the punch continues to move downward , squeezing upper and lower sheets until the punch reaches a near dead point.

4.Holding pressure: During the holding pressure stage of forging, the die should continue to maintain pressure for a certain period of time to prevent the sheet from rebounding, so that the upper and lower sheets can fully fill the annular groove and ensure that the rivet-free riveted joints are completely formed.

5.Back pressure: In this stage,the punch moves upward.There is an inverted cone on the punch , it’s easy to demoulding.Move the punch upward,then take down the riveted sheet. If it is an automated riveting with multiple points connected, the entire mold must be separated from the riveted sheet first, and then the sheet or mold is automatically moved before a new riveting is performed.

Process Competence

Dot connection: Using a simple round punch,on the SIMITCH pneumatic hydraulic clinching machine,through a stamping process,the connected plate can be squeezed into the corresponding die,so that it "flows" and deforms in the die,then producing a connection point without edges or burrs.

SKB f lat point connect ion: For some plates, the raised dots produced by SIMITCH dot connection may be a hindrance. Therefore, after processing the SKB dots, the raised part can be pressed back to form a flat point (+0.1mm) using a flat point mold.

Doub le point connect ion: This new connection method is a two in one solution.Using one set mold (punch and die) to make two connections in one press stroke. This aims to increase production efficiency and prevent the connection point from turning. Compared with a single round point, its shear strength is up to twice and the tensile strength is up to 1.5 times.

Rivet ing dot point connect ion: This connection is accomplished with a simple cylindrical rivet in a joining process using the drawing/pressing method. Similar to the circularjoint, the materials to be joined are not cut but guided through a die form, resulting in a very durablejoint - even in the case of thin materials.

Micro point connect ion: Micro circular connectors with a tip diameter of 1.5 to 2 mm are the solution for miniaturization of components. They are ideal for metal sheets with a thickness of 0.1-0.5 mm and narrow flanges, where conductivity between the connecting layers is outstanding.

Rectangu lar point connect ion ST: Rectangular point connection combines the process of cutting and deformation, and is mainly suitable for the connection of hard materials and stainless steel plates.

SKB Dot connect ion: This clinching uses a special SKB die, which consists of a fixed part and a moving part with 4-6 movable die pieces. The fixed part ensures accurate centering to form the connection point, the sheet material and the punch are centered relative to this fixed part, and the movable parts between the fixed parts guide and constrain the "flow" of the sheet material atthe connection point.

Three-flap mold connect ion: It has wider adaptability and better compatibility to sheet materials.
