Description
Technical Field
The utility model belongs to the technical field of numerical control slot sawing machine and specifically relates to a saw blade mechanism of numerical control slot sawing machine.
Background
Longeron type wooden pallet can all advance the fork in the four sides for fork truck, need open two fork pockets of advancing in the longeron below, according to different tray size and fork truck type, should advance fork pocket width size and be 200 ~ 300mm, degree of depth 30 ~ 80 mm. The feed fork groove is formed by cutting out a part of the processed longitudinal beam. At present, three modes are used for slotting the longitudinal beam of the wooden pallet, the first mode is the processing of a traditional small-sized band saw machine, the defects are that the efficiency is low, the sawing is carried out by manually pushing the timber to advance and rotate, only 1-2 pieces of timber can be processed at most each time, and the manual pushing speed is slow; in addition, in order to achieve regular cuts, lines of the notches need to be drawn on the longitudinal beams, and time is consumed; the precision is not enough, and because the material is pushed manually, the standard straight line is difficult to control, and the circular arc is more difficult to control; the wood strips are pushed manually, long-time force is exerted, and the labor intensity of workers is high.
And the second method comprises the following steps: the high-speed rotary cutting keyway planer consumes a large amount of electricity, because the width of the planer tool is equal to the width of the slot, each planer tool generally has the weight of 35kg and the diameter of more than 250mm, and can be driven by a high-power motor, and the power of the motor is higher by double-slot double-planer tools, which need to reach 15kw and can run continuously; the noise is large, and due to the characteristics of the planing tool and the planing, the noise is large and the wind noise is large during the cutting; the planed material is wood chips, and the residual value is very low; the occupied area is large, and a special collection field is needed because the wood chips are high in fluffiness; the tool is costly and cumbersome to replace. The price of each pair of cutters is 5000-. Because the cutting direction of the plane cutter is transverse, the period for keeping the blade sharp is short, and the blade which is not sharp needs to be polished. The keyway planer has complicated tool changing process and high labor intensity, and the tool changing needs procedures such as belt disassembly, belt pulley extraction and the like; for wood with high humidity, burrs are obvious in the notch cutting direction, when the blade is not sharp and still used, the machine is labored, the motor is easy to heat, the burrs are more, and secondary processing is needed; the height of the cutter and the number of the blades need to be adjusted for the slotted holes with different widths and depths, and a complicated process is needed as for cutter changing.
And the third is that: the numerical control slot milling machine has short service life of the cutter. Because the timber is milled for one circle and the efficiency is considered, the milling cutter only can select the current universal milling cutter with a smaller diameter, namely the double-edge milling cutter with the diameter of 6mm, the milling cutter with the small diameter is easy to break, and particularly, the milling cutter is easy to break when encountering the knots in the timber; the material adaptability is poor, because the cutting edge of the milling cutter is of a spiral structure, wood fibers are transversely cut off, and for wet materials or materials with longer wood fibers, burrs are obvious on one surface of a spiral outlet, namely dry wood, and obvious burrs are also formed at the final cutting position of the whole slotted hole, so that secondary processing is needed in the above conditions; the grinding technology of the cutter is high, and the cutter can be ground for a milling cutter without fracture, but the cutter is a spiral blade, so that the blade can be ground again to be sharp by the high grinding technology of a special grinding machine.
