Clinching (press joining) is the originative and determined technique for joining metal and non-metals. This is an innovative technology that forms clinch-lok joint which consists of a die and a punch. This lock is formed when the tool is squeezed to join a die and a punch with no use of supplement added material. These can be classified into rectangular and round tools. The procedure of clinching is a proven substitute for riveting, welding and screwing. Round tools include flat dies, fixed grooved dies and split dies. In plane directions, rounds tools show identical mechanical behavior. The main effectiveness is influenced by thickness of the sheet, material ductility and loading directions. In comparison to the round joining tools, rectangular tools require low joining force with respect to handle the staggered, straight and 90 degree axis. These are commonly used in the industries without damaging the surface.
Jurado tools are efficient with wide categories of machines including economical, light, and handy that represent innovative developments in the field of sheet metal working. The company was granted international and national patent for development and designs of latest techniques and clinching tools.
Advantages of the clinching tools
- The technique involves relatively lesser force.
- It helps to join sheet metals with the large differences in thickness.
- Capable to join high tensile strength and non ductile sheet metal material through the ductile one. Such as joining of spring steel, sheet metal and cast steel combinations.
- Non metallic material can be joined with the sheet metals such as paper, cardboard, plastic and rubber.
- You can simply join the high strength material while the tools have a long life with reduced press force.
- It requires no network with heat and allows clean working environment. This is one of the least expensive ways for the fastening of the material.
Joining process of the clinching tool: Characteristics
- On the die side of the material it requires a hole during the joining process of heavy sheet material.
- During the process one sheet of metal layer is formed.
- It has quick ability to absorb axial and radial forces.
- Multipoint capability and assembly components require exact positioning of the material.
Clinching is widely dominating welding technique as in Refrigerators, Washing machines, Vending machines, Window displays and Freezers.
Clinching tools are used to fit together building machinery such as Doors and windows frames, cranes, elevators, ventilation, garage doors, gutters, lighting, cable tray, floor and roof elements
Clinching tools applications
Clinching is suitable for the varieties of sheet metal components. These play major key role in the means of facilities and transport such as boats, railways, aircrafts, ships, trains and carriages. Suppliers and manufacturers are experimenting clinching automotive, railway sectors and lightweight construction in aerospace.
Chemical and energy production
Clinching technology has high performance of energy production in the chemical industries. Whether related to the traditional or renewable resources such as gas and oil. Clinching tools can resist in various weather conditions and have strong junction of interlock.
