Description

Band saw blade roller device

Technical Field

The utility model relates to a wood working machinery, in particular to band saw blade roller device.

Background

At the beginning of the sawing process, in particular the cutting process into the workpiece to be sawed, uneven and vibrating positions of the band saw blade frequently occur. This leads to shape deviations and high values of surface roughness in the cutting zone. For this reason, guide devices are often provided in order to ensure a defined operation of the saw band. However, a certain freedom of movement of the band saw blade can be achieved by the clearance in the guide. However, these known guides, which can also be designed as metal rollers, do not dampen the vibration behavior of the saw band during the cutting operation. If the guide is designed as a metal roller, slippage of the band saw band on these rollers can occur due to insufficient static friction between the roller and the band saw blade. Referring to fig. 1 and 2, a saw blade 2 'of a conventional band saw is guided by a roller 3' disposed on a saw clamp 1 ', the roller 3' is rotatably disposed on a fixing shaft 11 'extending from the saw clamp 1', but the roller 3 'of the guiding roller device has a faster and faster running speed along with the movement of the saw blade 2', so that the roller 3 'has a too high running speed, which causes insufficient static friction between the roller 3' and the band saw blade 2 ', and further causes unstable slippage of the band saw blade 2' on the roller 3 'or even the breakage of the saw blade 2', especially when an inner bearing of the roller 3 'is damaged, the roller 3' and the saw blade 2 'have hard friction, and thus the saw blade 2' has the problems of deviation, dislocation and the like.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a rational in infrastructure, can slow down, effectively protect saw blade rolling wheel device of band saw that the saw blade operates steadily to the gyro wheel.

In order to solve the technical problem, the utility model discloses take following scheme: the utility model provides a band saw blade gyro wheel device, includes saw clamp and gyro wheel, the saw clamp upper surface upwards extends and is equipped with the fixed axle, still includes pivot and bearing frame, the bearing frame sets firmly on the free end of saw clamp fixed axle, pivot one end is worn to locate on the bearing frame and the pivot other end is worn to locate on the bearing of gyro wheel, the outer periphery of gyro wheel is connected with the saw blade back contact of band saw machine.

In a further improvement, the outer circumferential surface of the roller is vertically connected with the back of a saw blade of the band saw machine in a contact manner.

In a further improvement, the side surface of the outer circumference of the bearing seat is fixedly connected with the free end of the saw clamp fixing shaft.

The improved band saw further comprises a lifting mechanism, wherein the lifting mechanism is arranged on the band saw body and connected with the band saw body and drives the saw clamp to lift up and down for adjustment.

By adopting the technical scheme, the beneficial effects of the utility model are that: through set up pivot and bearing frame between saw clamp and gyro wheel, because the gyro wheel drives the pivot when rotating and rotates and then make the gyro wheel inner bearing rotate and rotate on the bearing frame because of driving the pivot and slow down effectively, the life of gyro wheel inner bearing has been prolonged, effectual static friction between gyro wheel and the saw blade has been ensured, make the saw blade operation more steady, still can make the gyro wheel still can rotate on the bearing frame with the pivot whole when inner bearing damages simultaneously, the off tracking appears in the saw blade when avoiding gyro wheel inner bearing to damage, the dislocation scheduling problem, rational in infrastructure, can slow down gyro wheel inner bearing, effectively protect the saw blade to operate steadily, can extensively popularize and apply.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 3 and 4, preferred the utility model discloses a band saw blade gyro wheel device, press from both sides 1, gyro wheel 2, pivot 3, bearing frame 4 and elevating system 7 including the saw, the saw presss from both sides 1 upper surface and upwards extends and is equipped with fixed axle 11, the outer peripheral side of bearing frame 4 and the free end rigid coupling of saw clamp 1 fixed

axle

11, 3 one ends of pivot are worn to locate on the bearing frame 4 and the 3 other ends of pivot are worn to locate on gyro wheel 2's the bearing, 2 outer peripheries of gyro wheel are connected with 5 back vertical contact of saw blade of band saw machine 6, elevating system 7 is located on the 6 fuselage of band saw machine and elevating system 7 is connected and is driven the vertical lift adjustment of saw clamp 1.

The utility model discloses a set up pivot and bearing frame between saw clamp and gyro wheel, because the gyro wheel drives the pivot when rotating and rotates and then make the inside bearing of gyro wheel rotate because of driving the pivot and rotate on the bearing frame and slow down effectively, the life of the inside bearing of gyro wheel has been prolonged, the effectual static friction between gyro wheel and the saw blade that has ensured, make the saw blade move more steady, still can rotate on the bearing frame with the pivot is whole when still making the gyro wheel damage in inside bearing simultaneously, the off tracking appears in the saw blade when avoiding the inside bearing of gyro wheel to damage, the dislocation scheduling problem, rational in infrastructure, can slow down the inside bearing of gyro wheel, effectively protect the saw blade to operate steadily, can extensively popularize and apply.
