    Abstract: The aim of this invention is easy to use, practical, light, compact, mobile tool, designed for restoration of the formwork props. This tool very effectively removes uneven places and dents present inside the formwork prop without the need for electric power. No special premises or sites are needed for restoration of the formwork props. The tool is very compact and easily packed into a case-shaped box. When performing formwork prop restoration works, no special physical power of a person is necessary. All of the previously mentioned characteristics are ensured by the special design of this tool, where one ending is inlet into the damaged formwork prop close to the place, which is to be repaired, while the other ending, when using the screwdriver, is rotated around its axis. This rotary motion in one ending of the tool pulls the wedge, which is in the other ending of the tool, and, in this way, it spreads the plates, which touch the walls of the formwork prop, and evens them.

  • Patent number: 7584637
    Abstract: A method of bending a metal object, such as a tube, is provided that uses real time, closed-loop feedback of the actual springback of the object in order to modify the applied bending force or preprogrammed bending coordinates so that the final desired bend geometry is achieved. The variability of springback from object to object is thus accounted for and the number of objects that must be scrapped due to incorrect bends (over bend or under bend) is reduced. The method is carried out using an apparatus such as a rotary draw bender with a measuring device operable to measure actual bend coordinates of metal objects bent by the bender. A controller is operatively connected to the bender and the measuring device and is configured to control the bender to bend the metal objects at least partly based on measured bend coordinates provided by the measuring device.

  • Publication number: 20090049885
    Abstract: “The dent removal industry utilizes specialized tools and techniques to remove automobile dents. This invention is unique because it uses strong magnet(s) attached to the tool tip introducing a magnetic field thru sheet metal. The magnetic material can be neodymium iron boron (NdFeB), samarium cobalt (SmCo), or other strong magnetic material. A magnetic dust applied on the painted surface of the sheet metal near the dent indicates the tips position. Sliding the tip on the underside of the sheet metal near the dust and dent collects the material at the tip's position. Identification of the tip's location reduces the number of pressure flexes, eliminates the need for specialized lighting, frees the technician's posture, and does not require extensive and costly training. This invention and technique greatly improves the ease, accuracy, and speed of removing dents. Untrained individuals can thus remove dents.
