Abstract
The utility model relates to a portable band saw machine. A band saw is sheathed on a driving wheel and a driven wheel. A machine seat and an upper cover are hinged by a rotary shaft to form two parts of separate type. The main shaft end of a motor is provided with skewed teeth which are engaged with a skew gear fixedly connected with the driving wheel. A tensioning mechanism is arranged on the driven wheel. A load adjusting mechanism with a torsional spring is arranged on the rotary shaft. The machine seat is composed of a gripping mechanism. The utility model has the advantages of compact structure, reasonable layout, small size, light weight, portability and high automation level, and is suitable for open air and construction sites in fields.
Description
The utility model relates to a kind of band sawing machine, particularly a kind of portable band sawing machine.
Existing band saw mechanism is large-scale metal cutter, and volume is big, and weight is big, just can come into operation after the Installation and Debugging, can't carry, and therefore can't carry out outdoor or field work.
The purpose of this utility model is to provide a kind of and carries, operation, easy to maintenance, and the high portable band sawing machine of automaticity.
The purpose of this utility model realizes by following structure: support and loam cake are by the split type two parts of the hinged formation of rotating shaft, cover on it and be fixed with motor, this electric machine main shaft end is a helical teeth, it and central shaft are fixed on a helical gear engagement that covers, this helical gear is fixedlyed connected with driving wheel, and a cover tensioning apparatus is housed on follower, and band saw passes through from being fixed in the control panel groove that covers, a deferrable load mechanism is housed in rotating shaft, and support is made of gripping mechanism.
Therefore transmission structures of the present utility model is simple, and gearratio is big, and noise is low, shakes for a short time, can export preferably and turn round saw, has reduced volume again.Load mechanism of the present utility model can be adjusted, and the utility model can be processed the bar and the section bar of different metal model, adapts to the requirement of sawing feed.This mechanism structure is simple, and practical function is good.Have a cover strainer on the follower of the present utility model, be in tensioning state when making band saw in working order, to increase the frictional force between band saw and driving wheel and follower.The utility model also has a cover and clamps device, has dial, makes the utility model can cut out processing inclined-plane from 0-45 °.General structure compactness of the present utility model, rationally distributed, operate, use all more convenient.The utility model automaticity is higher, has improved Metal Cutting efficient greatly, is suitable for the outdoor or on-the-spot use of field construction.
