Abstract
The utility model relates to a multi-position pneumatic dogging vertical type band sawing machine tool. Front, back woodworking band sawing machine sets are set. Two opposite vertical woodworking band sawing machines capable of cutting log are arranged in each set. A pneumatic dogging body is provided with upper, lower cylinder vertical beams, a vertical connection plate and transverse beams respectively fixed on the front, back ends. A plurality of cylinders with piston rods and positioning poles are fixed inside along the vertical beams. Wood-fixing blocks are arranged on the piston rods. A bridge type groove-shaped beam and two upper guide rails are mounted above the machine set. A reducer, a drive wheel and an electric machine are fixed behind the transverse beam. Driven running wheels are arranged below the transverse beam and slide along the upper guide rail, thus the pneumatic dogging body is driven to move and transfer the material between two band sawing machines. A lower guide rail, upper, lower stabilization wheel sets are arranged in a trench. Compared with the existing single mechanically-clamped woodworking band sawing machine, the deformation due to single-surface cutting and end turning of the log is conquered and the cutting efficiency is greatly increased.
Description
(1) technical field: the pneumatic card of the multistation formula band saw lathe of standing motionless is a kind of wood processing equipment, is that the log of cutting down in the forest is processed into plank, belongs to wood sawing machine class (B27B).
(2) background technology: the equipment of existing processing log " the vertical wood working band sawing machine of band sport car " structure, feeding and method of clamping are following: see Fig. 7; Vertical wood working band sawing machine 1 comprises following saw wheel 1.3, upper wheel 1.2 and moves up and down saw blade 1.1 by what two-wheeled drove; Cut log from the top down with saw blade; Processed log 2 is placed on the sport car 4n, and with before the vertical X of sport car and then feeding, log is gripped by the iron claw 6n on the sport car support 5n.This log process equipment not enough as follows: 1. sport car advances feeding once, can only cut a slice in the log, and working (machining) efficiency is low.2. log can not once have been sawed automatically, though sport car repeatedly charging can cut multi-disc, when sawing on the last limit of iron claw retained part former wooden unit 2.2 at last; Because of colliding iron claw; Must dismantle the former wooden unit in last limit is turned over one side, log upset in last limit is yielding, and stirs and need employ plant equipment and manual work.3. see from the wood tissue structure that hard-hearted in the log, sapwood is that softer both the interior tensions of skin are inconsistent, so existing wood working band sawing machine adopts one-sided cutting, just causes the two sides stressed inconsistent, makes uncut former Muyi produce distortion.
Chinese patent also discloses some vertical or horizontal wood working band sawing machines, and its log method of clamping all is mechanical grip, and also is the single face cutting, the problem on deformation that all exists the former wooden unit in the last limit of cutting to need turn-over and single face cutting to produce.
