Self-Piercing Riveting Machine

Self-Piercing Riveting MachineThe main applications of SPR-Self Piercing Riveting is processing the new materials fastening for lightweight car productions, due to the important measures of lightweight car body is to introduce new material. Self Piercing Riveting can fasten the different metal material with good sealing and protect penetration function. The processes are more stable and the contact surface is more smooth, save much time and humans cost, lower energy consumption, small occupation area ,Applicable scope: coated steel sheet, aluminum,zinc, reinforced plastic, compound material etc.

Operating Principle：Blank holder move downward first for preloading tight the riveting material to prevent two metal pieces moving under riveting pressure. Then the power head move downward for piercing the upper material, in the hollowing block, the rivet tail opened and formed a bell shape to locking base material under the impact of power head.

Case 1: The thicker material should be put as base material if fasten the same metal material.

Case 2: The metal should be put as base material if fasten metal and non-metal material.

	No punching, no waste, no scrap iron
	Available for fastening Sandwich materials (non-metal material inserted between two metal material)
	No thermal stress concentration，it will not damage the material surface coating
	Higher Fatigue strength than traditional welding technology
	Available for fastening metal and non-metal materials and sandwich material.
	Good sealing and protect penetration function.
	Durable and stable quality
	Easy to carry out quality evaluation and non-destructive detection.
	High efficient, several riveting points completed in one stroke
	Low energy consumption, low noise and no soot emission
	Simple process, save human cost
	No damage the cladding and coating of materia
	Static connection strength is 70% than welding while the dynamic fatigue strength is much higher than welding.
	The application example of various material fastening by Self-piercing Riveting Machine.
	The analysis of joint strenght on different material fastened by Self-piercing Riveting Machine
	The types and parameters of Self-piercing Riveting Machine

Currently there are two kinds of manufacturing process for Bus Duct fastening,bolt fastening and Self-Piercing riveting. The method Bus Duct fastened by bolting was low efficient and take much more human cost, while if it is fastened by Self-Piercing riveting machine, it will increase 50% efficiency than that of traditional bolting method.
