Description

Technical Field

The utility model belongs to the field of equipment manufacturing, and particularly relates to a split combined synchronous sawing device.

Background

The workpiece sometimes needs to be cut at one end or both ends according to the processing requirements, so that the workpiece meeting the processing and manufacturing requirements is obtained.

For example, aluminum pipe sheets are used as one of the work pieces for large coolers, and have a large size, a maximum length of 9000mm and a width of 1000mm. The aluminum pipe piece is manufactured by embedding a plurality of aluminum pipes into aluminum fins and then tightly expanding the aluminum pipes and the fins together through special auxetic equipment. Due to the requirement of an auxetic process, two ends of the aluminum pipe are required to be reserved for a certain length, so that the aluminum pipe head can be conveniently grabbed during expansion connection. The reserved length is required to be cut off after the aluminum pipe piece is processed, the reserved lengths of the pipe heads of all aluminum pipes are kept consistent, the pipe heads of all aluminum pipes are required to be cut off once, the cut is required to be smooth, burrs are avoided, and the processing and manufacturing requirements of the aluminum pipe piece are met.

In order to increase the processing and manufacturing speed of the workpiece, sawing equipment is generally adopted to carry out cutting processing, and the existing sawing equipment mainly comprises the following three types:

1. hacksawing machine: the saw bow with saw blade reciprocates and is fed in the mode of the saw frame swinging around one fulcrum, and the machine tool has simple structure, small size and low efficiency. The motion track of the hacksaw machine saw blade is of a straight line type and an arc line type. The sawing machine can only be operated singly, two ends cannot be sawed synchronously, and the incision burrs are large, so that a workpiece is easy to damage;

2. band sawing machine: the annular saw belt is tensioned on two saw wheels, the saw belt is driven by the saw wheels to cut, the band sawing machine mainly comprises a vertical type saw frame and a horizontal type saw frame, the saw frame of the vertical type saw machine is vertically arranged, and a workpiece moves during cutting to cut curved contours of a plate material and formed parts; the saw frame of the horizontal band sawing machine is horizontally or obliquely arranged, is fed along the vertical direction or the swinging direction around a fulcrum, the saw band is generally twisted by 40 degrees to keep saw teeth vertical to a workpiece, the horizontal band sawing machine is divided into a scissor type band sawing machine, a double-upright type band sawing machine and a single-upright type band sawing machine, and the horizontal band sawing machine is divided into a manual type band sawing machine and an automatic type band sawing machine according to the use condition;

3. circular sawing machine: the circular sawing machine is mainly operated in a single mode, and even though a double-head sawing machine for processing aluminum profiles is mainly fixed on a linear guide rail, the sawing stroke is short, the size of a workpiece to be sawed is limited, and the circular sawing machine is not suitable for sawing workpieces with the same width and longer length as the aluminum segments with the width of 1000mm.
