Device for stable and efficient feed control of band sawing machine

Abstract

The invention relates to the technical field of mechanical devices, in particular to a device for stable and efficient feed control of a band sawing machine. The device comprises a workbench, a tool rest and a lifting device, wherein at least two guide columns are arranged on the upper end face of the workbench, the tool rest is connected with the guide columns and can move up and down, and the guide columns are connected with mounting holes on the tool rest and can play a role in guiding; and one end of the lifting device is connected with the tool rest, the other end of the lifting device isfixedly connected to the upper end face of the workbench, and the lifting device provides power to drive the tool rest to move up and down under the action of the guide columns. The tool rest is driven to stably move up and down through the lifting device, so that the service life of a saw blade is prolonged, and the machining precision is effectively improved; and a lead screw device is used, sothat the operation precision is high, the movement is stable, no vibration is generated during starting, crawling is linear at a low speed, the friction resistance is small, the trace feed is effectively controlled, and therefore the machining precision can be improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a stable and efficient feed control device for a band sawing machine. Background technique [0002] At present, during the use of the band sawing machine, the use of the power system of the band sawing machine will cause the saw band to vibrate, and the saw band itself will vibrate when cutting materials. Therefore, when the band sawing machine is used, the saw band will inevitably produce vibrations. Vibration, and the vibration of the saw band has a great impact on sawing, especially for band sawing machines with increased width. The vibration of the saw band will cause rough cut surfaces, the teeth will wear and become blunt quickly, and the life will be shortened.

[0002] At present, during the use of the band sawing machine, the use of the power system of the band sawing machine will cause the saw band to vibrate, and the saw band itself will vibrate when cutting materials. Therefore, when the band sawing machine is used, the saw band will inevitably produce vibrations. Vibration, and the vibration of the saw band has a great impact on sawing, especially for band sawing machines with increased width. The vibration of the saw band will cause rough cut surfaces, the teeth will wear and become blunt quickly, and the life will be shortened. At the same time, the vibration of the saw band will emit Abnormal sound, forming noise, the actual application effect is not ideal

The existing band sawing machine has the following defects when working: 1. The power of the band sawing machine is provided by the oil cylinder, the running speed is unstable, the machine tool is easy to shake, and the service life of the saw blade is greatly affected when sawing. When the oil cylinder provides power, the synchronization is not high

2. When adjusting the lifting speed, the response speed is slow and there is a certain hysteresis

3. When the band sawing machine is working, the running speed is unstable, but the feed accuracy is reduced.

[0003] Moreover, when sawing, if the machine tool shakes, it will not only shorten the service life of the saw blade, but also easily cause the saw blade to break, causing harm to human body and life.
