壓力式澆注機(jī)工作原理
Working principle of pressure pouring machine
鐵水經(jīng)擋閘板擋渣后,經(jīng)U形出水口無壓力流出,在鐵水表面張力作用下呈平穩(wěn)的圓形流束注入型腔.可編程序控制器和伺服系統(tǒng)控制扇形包的角速度和液面高度來控制鐵水的流速.其特點(diǎn)為:不帶氣、沖刷少、收包斷流快速干凈、飛濺少、鑄件成品率高、所有技術(shù)參數(shù)都可以通過觸摸屏輸入和修改.各種工藝參數(shù)都可以通過學(xué)習(xí)(示教)進(jìn)行設(shè)定,并且能把最佳澆注參數(shù)存入.再次生產(chǎn)同種產(chǎn)品時只需調(diào)出此參數(shù)即可.本設(shè)備結(jié)構(gòu)簡單、占地面積小、可以為現(xiàn)有造型線加裝,且故障率低,維修、保養(yǎng)方便,是理想的自動澆注設(shè)備.
The molten iron flows out without pressure through the U-shaped outlet after being blocked by the ram, Under the action of the surface tension of the molten iron, a stable circular flow beam is injected into the mold cavity. The programmable controller and the servo system control the angular velocity and the liquid level height of the fan-shaped bag to control the flow velocity of the molten iron. Its characteristics are: no gas, less erosion, fast and clean closure and disconnection, less spatter, high casting yield, all technical parameters can be input and modified through the touch screen. Various process parameters can be This equipment has the advantages of simple structure, small floor area, low failure rate, convenient maintenance and repair. It is an ideal automatic pouring equipment
