Abstract
The utility model discloses a cylindrical cutting tool for abrasive belts. The cylindrical cutting tool comprises a center shaft. Two ends of the center shaft are rotatably disposed on bearing blocks. The center shaft is sleeved with a tool mounting shaft which is provided with a plurality of trapezoidal grooves arranged in a circular array. The trapezoidal grooves and the center shaft are coaxial. The cylindrical cutting tool further comprises a plurality of cutters and fixing blocks; the fixing blocks are disposed at two ends of the tool mounting shaft; the cutters are slidably disposed in the trapezoidal grooves; the bottom ends of the cutters are fitted to the trapezoidal grooves; a spacer is disposed between each two adjacent cutters; the tool mounting shaft is provided with threaded blind holes; the spacers are fixed on the tool mounting shaft through bolts entered into the threaded blind holes; two ends of each spacer are in contact with the end faces of the corresponding cutters. If the spacers on two sides of the cutters are equal in size, abrasive strips cut by the cutters are equal in width; if the spacer on two sides of the cutters are unequal in size, spaces of the adjacent cutters are different, and the abrasive strips diverse in with can be produced while an abrasive belt is cut; accordingly, frequent replacement of the cutters in the machining process is avoided, idle time is shortened, and the cylindrical cutting tool is more practical.
Description
Technical field
The utility model relates to vertical abrasive band banding machine, specifically refers to a kind of tubular abrasive band cutting tool.
Background technology
Banding machine is a kind of equipment that wide roll of material is carried out to longitudinal cutting, can be divided into following a few class: for itemize paper, this is also the main product in current packaging facilities, and packaging market is often visible according to its scope of application; For itemize leather, dry goods, plastics, film etc. required industry; For itemize metal coiled material, as a point band steel, stainless steel, copper etc., it is mainly used in steel processing factory pod and determines steel market operator, steel rolling producer, electrical apparatus industry, automobile, stamping parts etc.
The operating efficiency of banding machine is relevant with following factor: itemize speed, yield rate, inoperative holding time, stability etc.Itemize speed is an important indicator of banding machine operating efficiency, if but yield rate is low, and not only can cause the operating efficiency of complete machine low, and can cause the rising of cost.Equally, if inoperative holding time is long, as: tune machine, tool setting, tool changing, reload, the consumption time such as processing problem is long, the speed of simple raising banding machine, also just seems unimportant.The stability of traditional banding machine is lower, and particularly, in long use procedure, the stability decreases of complete machine not only can affect the operating efficiency of banding machine, also can have influence on product quality, more can cause trouble and unnecessary waste to next procedure.In the time that cutter is cut apart abrasive band, because the sand grains hardness on abrasive band is higher, do used time wearing and tearing mutually at cutter and abrasive band, and when the width in the abrasive band of required cutting is not of uniform size, need to change cutter, greatly extend the non-working time, also caused the practicality of banding machine complete machine greatly to reduce.
Utility model content
The purpose of this utility model is to provide a kind of tubular abrasive band cutting tool, and the convenient cutting action that tubular abrasive band is carried out to different in width size, in improving banding machine overall utility energy, reduces the wearing and tearing of cutter.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tubular abrasive band cutting tool, comprise central shaft, the two ends of central shaft are rotated and are arranged on bearing block, on described central shaft, be set with dress cutter shaft, on dress cutter shaft, have the dovetail groove that multiple annular arrays distribute, described dovetail groove is coaxial with central shaft, also comprise multiple cutters and fixed block, fixed block is arranged on the end, two ends of dress cutter shaft, described cutter is slidably arranged in dovetail groove, and the bottom of cutter coordinates with dovetail groove, between adjacent two cutters, spacer is installed, dress cutter shaft is provided with tapped blind hole, spacer passes tapped blind hole by bolt and is fixed on dress cutter shaft, the two ends of spacer and the end contact of cutter.When the utility model work, under the drive of central shaft external drive equipment, start rotation, the dress cutter shaft band cutter being sleeved on central shaft starts circumgyration incision, cutter is slidably arranged in dovetail groove, and cutter is fixed on dress cutter shaft by spacer, the size of spacer is selected to carry out according to the width in required abrasive band, in the time that the ambilateral spacer size of cutter is identical, be that the emery stick width that cuts out of cutter is identical, in the time that the ambilateral spacer size of cutter is not identical, spacing between two adjacent cutters is not identical, make in abrasive band when cut the emery stick of the multiple width of output simultaneously, avoid the frequent cutter of changing in process, shorten the non-working time, improve widely practicality of the present utility model, dovetail groove is coaxial with central shaft, and the length of the Length Ratio central shaft of dovetail groove is slightly short, can ensure cutter the moving freely of long distance on dress cutter shaft, ensure that the spacing between two adjacent cutters is adjustable flexibly, the emery stick width range cutting out is larger, and practicality is higher, multiple dovetail groove annular arrays are distributed on dress cutter shaft, and multiple cutters are kept at a certain distance away in same planar annular, in the time of cutter High Rotation Speed, reduce the wearing and tearing between cutter and abrasive band, improve service life of the present utility model.
