Production of blanks for end pieces by splitting

The manufacture of end pieces of various shapes makes it possible to use rationally fine-grained wood in the form of segments of coniferous tops and segments of wood processing. Based on end blocks, highly artistic floors can be made according to individual projects in residential and public buildings. The technology of manufacturing wooden floor coverings from end checkers has a significant drawback, which is that the vertical edges of the checkers on pre-cut cylindrical blanks were carried out by contour pressing, which significantly complicates production. As part of this work, a method and equipment have been developed for producing prismatic end pieces by splitting. According to the proposed method, buckled round logs (blanks) are placed in a vertical feeder. Using a pusher, the workpiece is pushed longitudinally onto a square hollow body, the end cutting edge of which is made in the form of evenly alternating triangular teeth having two cutting edges symmetrically arranged at an angle of 45° relative to the feed velocity vector of the workpiece onto the body. On the outside of the housing there are longitudinal knives made flat and radially positioned relative to the axis of the housing. As a result of the advance of the workpiece through the body, an end piece having a cross-sectional profile corresponding to the internal cross-sectional profile of the hollow body is cut out and extruded. At the same time, with the help of longitudinal knives, the peripheral part of the timber is split into blanks in the form of a split hump. The high quality of the profile blanks is achieved by obtaining a given transverse profile of the workpiece at a greater length than its analogues. This is explained by the fact that when processing at the proposed installation, the tool being implemented with a smaller cutting angle cuts rather than splits the wood at the initial stage of implementation.
