Abstract
The utility model relates to a circular saw, and settles the problems of low sawing efficiency easy saw clamping of disc saw and sawing length restriction of band saw. A circular saw blade is vertically provided between two slide way trolleys. A supporting plate which is fixed with the slide way trolley is respectively provided at the upper side and the lower side of the circular saw blade. Each supporting plate is provided with supporting wheels. The supporting wheels abut against the inner toroidal surfaces or outer toroidal surfaces which are provided at the upper side and the lower side of the circular saw blade. The other toroidal surface of the circular saw blade is provided with sawteeth. The circular saw blade is provided with a rotation driving mechanism and is provided with guiding wheels fixed with a supporting frame at the front end face and the back end face of the circular saw blade. The circular saw overcomes the problems of low sawing efficiency and easy saw clamping in prior-art circular saw, and furthermore overcomes the problem of transverse or longitudinal sawing length restriction of the workpiece in sawing by the prior-art band saw. While the workpiece is sawed from the inner ring to the outer ring of the circular saw blade, the circular saw has the advantages of: simple structure, easy operation, low cost, etc.
Description
Technical field
The utility model relates to sawing machine, is specially the circular saw of the big-and-middle-sized workpiece of a kind of suitable saw.
Background technology
Sawing is the starting point of metal cutting processing, as composition link important in the part processing process, its advantage is can economical with materials, reduce the secondary operations amount and enhance productivity, and therefore, sawing machine is to be widely used in fields such as iron and steel, machinery, automobile, shipbuilding and mine.Circular saw and belt saw are the existing sawing devices that generally uses, circular saw comprises the circular saw bit that is fixed on the turning cylinder, workpiece can only lean on circular saw bit the first half to carry out sawing, the low easy binding in sawing process simultaneously of cutting-rate, be used for the sawing of stone material more, sawing to steel and iron parts must make circular saw have high rotational speed, be applied in the sawing of iron and steel parts and the belt saw is most, the belt saw comprises vertical belt saw and horizontal belt saw, because the belt saw is by at least two saw wheels saw blade to be propped up to surround an annular enclosed space structure, the horizontal or ripping length of workpiece is subjected to the restriction of saw blade position during sawing.
Summary of the invention
The utility model exists low and easy binding of cutting-rate and belt saw to have the problem of sawing length limited system in order to solve existing circular saw, and a kind of circular saw efficiently is provided.
The utility model is to adopt following technical scheme to realize: circular saw, comprise up and down slideway and the slideway car that has driving mechanism that lays respectively on it, vertically be placed with the annulus saw blade between the two slideway cars, the both sides up and down of annulus saw blade are equipped with and the fixing gripper shoe of slideway car, every gripper shoe is provided with support wheel, support wheel abuts against the annulus saw blade up and down on the interior anchor ring or cylindrical anchor ring of both sides, have sawtooth on another anchor ring of annulus saw blade, the annulus saw blade is provided with the rotary drive mechanism that makes its rotation and is equipped with on the front/rear end of annulus saw blade and the fixing directive wheel of gripper shoe.Rotary drive mechanism described in the utility model is a prior art, has the various deformation structure, realizes for those skilled in the art are easy.The driving mechanism that drives the slideway car comprises the leading screw that is enclosed within on the slideway car, every rhizoid thick stick two ends all are fixed with the sprocket wheel that drives its rotation by chain, at first start rotary drive mechanism during work, the annulus saw blade rotates, rotate by the drive on the leading screw under the driven by motor then, make down leading screw and on sprocket rotation, because lower sprocket is connected by chain with upper sprocket wheel, thereby realize that two rhizoid thick sticks synchronously rotate, and then the drive of the gripper shoe on realization slide trucks annulus saw blade is done rectilinear motion, can realize the sawing campaign of annulus saw blade like this, because position fixing and support annulus saw blade is distributed in the both sides up and down of annulus saw blade, the mid portion that is available circular saw sheet cuts, be not subjected to stopping of circular saw axle center place's rotating shaft, reduce the probability of binding when having improved cutting-rate effectively, nor be subjected to the restriction of belt saw structure, under the different situation of workpiece length and width, also can not influence the length of sawing.
Rotary drive mechanism comprises the motor that is fixed on the gripper shoe, the output shaft of motor is connected with the driving wheel of its face of cylinder near annulus saw blade front/rear end upside or downside, when carrying out cutting operation, starter motor, driving wheel rotates thereupon, because the extruding of frictional force and two driving wheels, thereby realize that the annulus saw blade is to opposite spin.
Rotary drive mechanism comprises support wheel, have on the external cylindrical surface of support wheel tooth and with support wheel near the interior anchor ring of annulus saw blade or the cylindrical anchor ring on have tooth with the engagement of the support wheel face of cylinder, the place, axle center of support wheel is fixed with motor, when driving the rotation of annulus saw blade, the driven by motor support wheel rotates, and rotates thereby drive the annulus saw blade.
The annulus saw blade up and down quantity of the support wheel of both sides is two, and the annulus saw blade not only can play fixation preferably when sawing like this, and the annulus saw blade is stressed even, is difficult for deforming.
Circular saw described in the utility model is by improving dexterously, not only overcome the problem of the low and easy binding of original circular saw cutting-rate, and overcome existing belt saw when sawing workpiece laterally or the problem that is restricted of ripping, can realize that workpiece has simple in structure, operation and low cost and other advantages easily when sawing is carried out in annulus saw blade inner ring or outer ring.
