Description

Visual tension adjusting device for band saw machine Technical Field The invention belongs to the technical field of band sawing machines, and particularly relates to a visual tension adjusting device for a band sawing machine. Background The saw band of the band saw machine can be heated and expanded in the working process, so that the tensioning force is reduced, and the longer the saw band is, the larger the tensioning force change is. The saw belt is expanded by heating and then the tension is reduced, so that the cutting force of the saw belt is reduced and the cutting effect is poor, and the saw belt tension is reduced, so that the transverse swing amplitude of the saw belt is increased, and the saw belt is easily broken due to uneven stress, so that the normal production is influenced. The saw band of the band saw machine can ensure the sawing stability, reduce abnormal jitter, improve the surface quality of a saw section and prolong the service life of the saw band only by working under a certain reasonable tensioning force. The existing tension adjustment is manually adjusted, is labor-consuming, low in efficiency, and also adopts a hydraulic tension mechanism and a counterweight tension mechanism, so that the structure is troublesome to manufacture and has poor adaptability with a band saw machine. Disclosure of Invention The invention provides a visual tension adjusting device for a band saw, which solves the problems of low tension adjusting efficiency of the existing band saw and poor adaptability of the existing tension adjusting mechanism and the band saw. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides a visual tensioning force adjusting device for band saw machine, includes unable adjustment base, unable adjustment base is connected with the movable base through taking shoulder round pin axle, movable base both sides fixedly connected with conducting bar, wear to be equipped with adjusting screw on the movable base, be connected with the shaft in the vertical direction of adjusting screw, tension kicking block, tension spring and holding screw have been set gradually to the adjusting screw inside of shaft one side, the inside tension indication pole that is provided with of adjusting screw of shaft opposite side. Preferably, U-shaped grooves are formed in two sides, close to the end portion of the adjusting screw rod, of the wheel shaft, and the U-shaped grooves are connected with the guide bars in a sliding mode. Preferably, the side surface of the movable base is provided with a screw hole. Preferably, the whole adjusting screw is a through hole pipe fitting, the middle part of the adjusting screw is of an external thread structure and is matched with a screw hole on one side surface of the movable base. Preferably, the tension jack is connected with the tension indication rod through a screw. Preferably, the tension spring is in abutment with the axle. Preferably, the side of the tension indicating rod far away from the wheel axle is carved with a spring compression amount and a corresponding saw band tension value. Preferably, a threaded hole is formed in one side of the adjusting screw close to the set screw. Preferably, one side end part of the adjusting screw far away from the set screw is provided with a hexagon head structure. Preferably, an inclination adjusting screw is arranged on one side of the movable base. Compared with the prior art, the visual tension adjusting device for the band saw has the beneficial effects that the visual tension adjusting device for the band saw is provided, the whole device is fixed on the band saw through the fixed base, the angle is adjusted through the adjusting screw rod, the wheel shaft is driven to adjust the tension, the mechanism can simply and conveniently adjust the tension value of the band saw and the inclination angle of the idler wheel, the structure is compact, the operation is convenient, and the value of the tension value can be read in real time.
