Flangeless console disk cutting tool
(57) Abstract:The invention relates to industries that use materials processing disk cutting tool, in particular sawmill and compressfile production. Flangeless console disk cutting tool, comprising directly from the disc with a cutting ring mounted on the axis of the intermediate shaft by means of permanent connection (soldering, welding, adhesive connection, and so on), is fixed in the spindle and under predetermined angles to the plane of the disk are fixed subsequent disk cutting tools in the additional spindles of the machine. As a result of use of the invention is provided by layer-by-layer sequential blanking out of the array with the passage of the cutting tool along the plane of the disk on the entire thickness of the array. 2 Il. The invention relates to industries that use materials processing disk cutting tool, mainly in timber and compressfiles production.A device - console circular saw ( disc cutters, circular saws, circular abrasive tool according to the invention N 601150,to the value of the disk on the shaft or intermediate shaft fixing on him a pair of screw-nut.The disadvantages of the known devices is the lack of the possibility of sequential layer-by-layer cut from solid material of the workpieces along the plane of the disk depths, large difference of the radii of the edges of the disc and a supporting flange with nut, due to the operation or riusa segments in an array of material or spallation (destruction) of the workpiece.The purpose of the invention is through the use of ngaremlengui design flangeless console disk cutting tool to provide a consistent layered cut blanks from the array with the passage of the cutting tool along the plane of the disk on the entire thickness of the array.The aim is achieved in that according to the proposed design of the disk cutting tool, comprising directly from the disc with a cutting ring mounted on the axis of the intermediate shaft by means of permanent connection (connection by soldering, welding, adhesive bonding, and so on),is fixed in the spindle and under predetermined angles to the plane of the disk are fixed subsequent disk cutting tools in the additional spindles of the machine for cutting blanks from an array along the planes of the cutting disks, since the wafer discapline tool. The proposed design allows you to crash into the array as one cutting tool, and more than one.In Fig. 1 shows a cantilever wafer disk cutting tool of Fig. 2 - way layered cutting tool blanks from an array.Device for cutting wafer saws consists of the blade 1, United with him on the axis of the permanent connection of the intermediate shaft 2.The operation of the device and the operation of the process occurs as follows.Cantilever wafer disk cutting tool secured to the spindle of the machine located at a given angle and runs into an array of material on the thickness and the width of the workpiece equal to not more than the difference of the radii of the cutting edges of the disk and the intermediate shaft. After cutting the first (and subsequent blanks) block spindles with disc cutting tools is served on one of the specified dimensions of the workpiece and re-cutting tool in the array to complete the cutting of the specified layer. Flangeless console disk cutting tool comprising a disk grinder crown, characterized in that the disk grinder crown connected on an axis intermediate Polozhennyh at a given angle to each other with the possibility of layer-by-layer cutting pieces from an array.
FIELD: mining industry, particularly open-cast mining, particularly to produce natural stone blocks from sheet deposits by open-cast mining.
SUBSTANCE: method involves forming benches in each separate deposit so that production deposit is arranged at bench bottom; excavating mineral blocks by moving hydraulic excavator bucket teeth under productive deposit bottom and removing the blocks having natural configuration due to applying hydraulic action of excavator boom, handle and bucket to block with the use of natural deposit fracture porosity, which defines configuration and volume of produced blocks.
EFFECT: increased output, possibility to produce blocks from thin sheet deposits along with maintaining natural block volumes.
FIELD: mining industry, namely, high capacity (with load capacity over 40 tons) loading and transporting machines for underground and open mining operations.
SUBSTANCE: loading and transporting machine includes loading tool, consisting of bucket with impact teeth, boom and controlling hydro-cylinders, driving mechanism and force plant. Frontal wall of bucket is made with part extending beyond its side walls shaped as isosceles triangle or shape close to that for distance not less than 1/3 of its total length. Working edge of frontal wall of bucket is formed by even sides of triangle. Impact teeth are mounted along the axis of front wall, near side walls and with step of 3÷5 of width of impact tooth. Back wall of bucket is made inclined relatively to front wall at an angle more than 90°.
EFFECT: increased efficiency of machine operation due to lowered resistance of insertion of bucket into stack of rock.

SUBSTANCE: invention relates to mining industry and can be used at open development of carbonate deposits for the purpose of complex preparation for processing mineral stock. Taking into account preliminary estimation based on acoustic fracturing indicator, specific transformation component is determined additionally for each unit by selecting zones in the direction and depth of fractures by means of sections profiling with determination of the propagation speed of longitudinal, transverse elastic waves in the units and depending on the density, distinguishable strength and thermophysical properties of the selected zones by means of software for specifying the direction of stratification, type of carbonate rocks and prediction of energy impact parameters on the selected unit zones, then it is performed, leaving the integrity of strong rock blocks, first, selective extraction of specified units zones for producing chips of various grades and carbonate raw material with the help of jib pit machine, then recess of strong rock blocks is made.
EFFECT: technical result consists in improvement of production efficiency and complexity of carbonate mineral stock, differentiation of the obtained product with increase in its commercial cost, increase in safety, reliability of operations and reduction of capital costs.
SUBSTANCE: invention relates to mining industry and can be used in stone blocks production. Method includes formation of bench, block delineation by blast holes system located in vertical, side and horizontal planes, blast holes filling with not explosive destructive means, block separation from formation by creating of stretching forces along its contour, bench side surface is formed with angle of 90°, in vertical blast holes arranged along block length sections of detonation cord are placed and sealed with plug, initiating detonation cord and block is shifted into stripped area under detonation wave effect.
EFFECT: higher safety of operations, excluding of additional works on chipped off block displacement and obtaining of regular-shaped blocks.
