Vertical sawing machine

Abstract

The invention relates to the technical field of sawing equipment, in particular to a vertical sawing machine. The vertical sawing machine comprises a machine body, a saw frame, a tool table, a clamping unit, a motor and a controller. The saw frame is arranged in the middle of the rear end of the machine body. The left side and the right side of the upper portion of the machine body are provided with mounting seats. Two parallel lead screws are arranged between the mounting seats. The tool table is driven by the lead screws to adjust the feeding position on the machine body. Because the feedingmovement of the tool table and clamping block shaking occurring during workpiece sawing can damage the clamping effect in the process of sawing clamped long irregular workpieces, and the machining precision of the sawing machine is influenced, an adjustable pressing block is arranged on the clamping block to further clamp the long irregular workpieces. The tool table is mounted on a lead screw pair and is matched with the precise control function of the controller to stabilize the feeding rate of the workpiece during sawing, and the machining precision of the sawing machine is improved.

Description

technical field [0001] The invention relates to the technical field of sawing equipment, in particular to a vertical sawing machine. Background technique [0002] The sawing machine is a kind of cutting equipment, which can be divided into two categories: horizontal and vertical. The vertical band sawing machine is an internationally popular and indispensable machine for industrial development. The sawing machine can cut straight and wave materials in various shapes and angles. Saw bands of different specifications achieve high-efficiency cutting. [0003] For the vertical band sawing machine in the prior art, there is the defect that the machining accuracy of the sawing machine needs to be controlled manually, and the machining accuracy is poor; especially when the sawing machine processes long irregular workpieces, the effect of clamping and beating is not stable enough, so that The jitter generated during the sawing process of the sawing machine will affect the processin...

Problems solved by technology

[0003] For the vertical band sawing machine in the prior art, there is the defect that the machining accuracy of the sawing machine needs to be controlled manually, and the machining accuracy is poor; especially when the sawing machine processes long irregular workpieces, the effect of clamping and beating is not stable enough, so that The jitter generated during the sawing process of the sawing machine will affect the accuracy of the sawing machine

[0004] There are also sawing technical solutions for some vertical sawing machines in the prior art. For example, a Chinese patent with application number 2013104653727 discloses a vertical sawing machine, which includes a base, a bed and a saw frame. The base is provided with an integral lifting cylinder; the upper part of the bed is provided with a workpiece clamping device, the bed is provided on the second board, the second board is provided on the upper part of the base, and the upper part of the second board is provided with the first board. The frame is set on the first board, the first board is provided with a forward and backward moving device between the first board and the second board, and the second board is provided with a left and right moving device between the second board and the base; the driving wheel is fixedly arranged on the saw frame and the driven wheel, the driving wheel and the driven wheel are wound with a saw blade; this technical solution solves the problem of manual assisted sawing, and the saw blade can be twisted to a certain degree at the same time, which increases the life of the saw blade; The impact of vibration on the clamping effect of the workpiece, the vibration generated during the sawing process of the sawing machine will destroy the clamping effect of the clamping device, making the processing accuracy of this technical solution not stable enough
