Band-sawing machine for carpenters

Abstract

The invention discloses a band-sawing machine for carpenters. The band-sawing machine comprises a machine frame, an upper shield, a lower shield, a workbench, an upper saw clamp, a lower saw clamp, an upper wheel and a lower wheel. The upper wheel is arranged in the upper shield, the upper wheel is arranged on a shaft, and the shaft is arranged on a fixing frame. The upper end of the fixing frame is connected with a connecting frame, and the lower end of the fixing frame is connected with an adjusting plate. The connecting frame is fixed to a panel of the upper shield through a bolt. A deviation adjusting nut is arranged at the lower portion of the panel of the upper shield, the deviation adjusting nut is connected with an adjusting pin, and the adjusting pin penetrates through the panel of the upper shield to be in contact with the adjusting plate. An adjusting handle is arranged on the panel of the upper shield, and the adjusting handle is connected with the fixing frame. By the adoption of a novel saw clamping structure, the band-sawing machine for carpenters has better and more stable guiding performance. An air spring is adopted for assisting the workbench in adjusting the inclined degree, and an automatically adjusting function is achieved. An efficient, fast, and convenient adjusting and tension device is adopted to conduct fast adjusting and tensioning on a saw wheel, the use requirement is met, and economic efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of woodworking machinery, in particular to a woodworking band saw machine. Background technique [0002] Woodworking band saw machine, a saw machine that uses a ring-shaped endless band saw blade as a saw tool, and makes a one-way continuous linear motion around two saw wheels to saw wood. It is mainly composed of bed, saw wheel, upper saw wheel lifting and pitching device, band saw blade tensioning device, saw blade guiding device, worktable, guide plate and so on. The bed is made of cast iron or steel plate welded. The upper saw wheel lifting device is used to load and unload and adjust the tightness of the band saw blade; the upper saw wheel pitching device is used to prevent the band saw blade from falling off the saw wheel during sawing. The band saw blade tensioning device can endow the upper saw wheel with elasticity to ensure the stability of the band saw blade tension during operation; the old typ...

AI Technical Summary

Problems solved by technology

[0003] No matter what type of woodworking band saw machine, the contact mode between the saw card and the saw blade is line contact or surface contact, and its jurisdiction is very narrow, so it is easy to cause bias in the guide

At the same time, the inclination of the workbench is adjusted manually, which is bulky and inconvenient

Most woodworking band saw machines do not have an effective saw wheel adjustment tensioning device, which cannot fully meet the needs of use
