Clamping feeding device of band sawing machine

Abstract

The invention provides a clamping feeding device of a band sawing machine. The clamping feeding device of the band sawing machine is reasonable in design and compact in structure, and is safe, reliable and convenient to use by the adoption of clamping and conveying with an oil hydraulic cylinder. Due to the fact that a positioning pressing device is arranged on a crossbeam, after a band saw bladeis inserted into a channel, the back of the band saw blade is attracted to magnet strips, the band saw blade can be attracted through the magnet strips, the band saw blade is prevented from sliding down in the process of upward stepping, thus, the compaction degree of a saw band can be adjusted, the sawing toughness of the saw band is guaranteed, the problem that the saw band generates an irregular phenomenon and massive vibration during sawing is avoided, and meanwhile the problem that the saw band produces screams during sawing is avoided. The height of the upper end of a roller is adjustedthrough lifting with two lifting oil cylinders, the front end of a workpiece material is automatically adjusted to the same plane of a clamping workbench during automatic feeding of the band sawing machine, smooth feeding is guaranteed, and the clamping feeding device of the band sawing machine has the advantages of simple structure, good effect and the like.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a clamping and feeding device for a band sawing machine. Background technique [0002] The band sawing machine must fix the workpiece during work, and the clamping vise is generally used to clamp and fix the workpiece. At present, the clamping vise of a general band sawing machine includes a movable pliers, a fixed pliers, a clamping cylinder of the movable pliers, a hand wheel and a screw rod arranged on the vise workbench, and the clamping cylinder of the movable pliers is installed at one end of the vise workbench On the top, the fixed pliers are fixedly installed on the other end of the vise workbench. One end of the screw rod protrudes from the piston shaft tube in the clamping cylinder of the mobile vise and the screw hole of the slider of the mobile pliers in turn toward the direction of the fixed pliers. The other end of the screw rod Install the handwheel...

AI Technical Summary

Problems solved by technology

However, when the workpiece is an irregular material, the workpiece is likely to produce a small amount of displacement only by pushing and clamping on one side of the moving pliers, thereby reducing the sawing accuracy of the sawing machine and affecting the sawing performance of the sawing machine

[0003] At present, when the existing horizontal band sawing machine saws metal materials, since the saw blade or saw band is guided by a guide device, and the metal material has a certain hardness, when sawing, the saw blade or saw band The belt often vibrates greatly, resulting in irregular sawing or jamming, resulting in the problem of sawing waste. At the same time, this situation also leads to the problem of screaming of the saw blade or saw band when sawing.
