The fast acting F-clamp is an indispensable tool for woodworking. It is simple in structure and skillful in application. It is a good helper for woodworking.
How is the fast acting F-clamp constructed?
How to use the fast acting F clamp?
What are the material properties of the Quick Acting F-Clamp?
The fast acting F-clamp includes a guide rod, one end of which is fixed with a fixed arm, a movable arm pushed onto the rod body, a handle screw installed near one end of the movable arm, and a lower pressure block is installed on the top of the handle screw, and the corresponding fixed arm is equipped with a lower pressure block. One end of the lower press block is formed with an upper press block, the lower part of the guide rod is provided with a hexagonal hole and the lower end of the guide rod is provided with a bayonet to prevent slipping of the guide rod.
Slide the movable arm by hand, the movable arm must be parallel to the guide rod when pushing, otherwise it will not slide, slide to the width of the workpiece, that is, the workpiece can be placed between the two lever arms, and then rotate the movable arm slowly. Screw bolts are used to clamp the workpiece, adjust it to the appropriate strength and release the workpiece to fix the workpiece. Note: There is a bayonet on the guide rod that can prevent the guide rod from slipping and ensure that the workpiece does not come loose when clamping the workpiece. On each of the two lever arms there is a plus block to prevent contamination of the workpiece with heavy clamping of the workpiece. Ensure that the surface of the workpiece is level.
Metal can improve its structure and mechanical properties after forging. After the casting structure has been deformed by the forging process, the original coarse dendrites and columnar grains become an equilateral recrystallized structure with finer grains and uniform size due to the deformation and recrystallization of the metal, resulting in the original segregation and recrystallization in the steel ingots. Porosity, pores, slag inclusions, etc. are compacted and welded, and the organization becomes more compact, which improves the plasticity and mechanical properties of the metal.
The mechanical properties of castings are lower than those of forgings made of the same material. In addition, the forging process can ensure the continuity of the metal fiber structure, so that the fiber structure of the forging matches the shape of the forging, and the metal streamline is complete, which can ensure the parts have good mechanical properties and long service life. Forged parts produced by precision die forging, cold extrusion, hot extrusion and other processes are unsurpassed by castings.
