Description

Semi-automatic tool setting device of splitting machine

Technical Field

Background

It is known that composite material tape winding equipment needs to use 5mm and 10mm prepreg tapes to produce the composite material tape by a winding process. The production process of the prepreg tape comprises two production processes, one is to directly prepare the narrow prepreg tape, and the production process of the composite prepreg tape limits the slow production speed and has higher monofilament processing cost. The other method is to prepare wide prepreg cloth (1000mm and 1270mm) and then process the cloth into prepreg tapes of 5mm and 10mm by adopting a slitting process.

Because the composite material is formed by compounding resin and high-strength fibers, the composite material is difficult to cut and cannot be cut by using a press cutting mode. The existing better processing method is a shearing process, the shearing process needs to match an upper shearing knife and a lower bottom knife, the upper shearing knife needs to be inserted into a gap of the lower bottom knife, and then the upper shearing knife moves transversely to enable the upper shearing knife and the lower bottom knife to contact with each other and exert acting force with each other.

In the tool setting process of the upper shearing knife and the lower bottom knife, the upper shearing knife needs to be manually folded and the lower bottom knife needs to be close to ensure that the cutting edge of the upper shearing knife is aligned with the gap of the lower bottom knife (the cutting edge of the upper shearing knife is prevented from cracking), and then the upper shearing knife is manually folded continuously. The above work is difficult and time-consuming because of the heavy weight of the cutter, and there is easily an operator injury or equipment damage caused by misoperation.
