擠塑機組的切割機結(jié)構(gòu)設(shè)計
摘要
在切割機行業(yè)里，隨著數(shù)控切割技術(shù)飛速的發(fā)展，傳統(tǒng)的圓盤切割機目大多只運用在自動化程度低、切割斷面簡單、精度不高的場合，但數(shù)控切割機存在成本高、結(jié)構(gòu)復(fù)雜、維修困難等缺點，不適宜在塑料生產(chǎn)線上使用。
擠塑機組的切割機，運用于管材塑料擠出生產(chǎn)線上，管材在牽引裝置的牽引下不間斷地連續(xù)出料，切割機要在運動中完成規(guī)定長度的切割。在傳統(tǒng)的圓鋸片切割機里運用了機電一體化技術(shù)，由PLC控制各個氣動換向閥的線圈，由氣缸帶動工作臺使其與管材的速度相同以保證切口平整，并且由氣缸驅(qū)動切割裝置的上下移動完成順序切割過程，用光電開關(guān)來控制管材的長度，實現(xiàn)對管材的準(zhǔn)確定長切割并將成品送出切割機臺面，切割后自動返回初始位置等待下一次切割循環(huán)。本課題實現(xiàn)了機械設(shè)計、電器控制和氣動控制的有效結(jié)合，達到了生產(chǎn)自動化、效率高、切割精度好的目的。這種切割機具有控制方便，性能穩(wěn)定，結(jié)構(gòu)簡單，調(diào)節(jié)、維修方便，生產(chǎn)率高等優(yōu)點，具有廣泛的應(yīng)用前景。

The Design of Structure of the Cutting Machine for Extruder Equipment
Abstract
In the cutting machine industry, with the rapid development of CNC cutting technology, the conventional disc cutting machines are merely apply to the occasions which’s automation level is low , cutting section is simple, accuracy is not high. As the CNC cutting machine’s cost is high, structure is complex, maintenance is difficult and other shortcomings, the CNC cutting machine is not suitable to apply to the plastic production lines.
The cutting machines of extruder apply to extrusion line of plastic pipe. With the traction by the traction apparatus, pipe feed continuously. Cutting machine cut the plastic pipe into requested length, that the action was completed in motion. The mechatronics technology is applied to the traditional circular saw cutting machine. Using PLC to control the pneumatic valves, the whole work table is driven with pipe bench the same speed by the cylinder to ensure smooth incision. And the cylinder drive the cutting device vertical movement in order to complete the process of cutting; Using optical switches to control the length of pipe , and achieve the accurate fixed-length cutting of the pipe and finish sending the products out of cutting machine table. After finishing cutting, the machine is back to initial position automatically, and wait for the next cutting cycle. The subject realize the effective combination of mechanical design, electrical control and pneumatic control. That achieve the automatic production, high efficiency, good precision cutting purposes. This cutting machine is easy to control, stable performance, simple structure, easy to maintenance, high productivity advantages. It has broad application prospects.
