800吨铝棒型材挤压机该机是一种新型的铝棒型材挤压机,用于铝或铝合金的棒材及各种型材的挤压。如果在挤压杆上装置一个固定心棒,还可以挤压管材。本机可采用平模和锥模挤压。本压机为三柱卧式结构。其主体由前梁、挤压筒移动缸、挤压容室、立柱部件、活动横梁、后梁及机架等部分组成。挤压容室由挤压筒外壳、加热器、挤压筒三部分组成。挤压筒为两层厚壁筒采用热压配合的组合结构,内衬的内径为φ120毫米,挤压筒外壳中装有10个功率为3～4千瓦的电阻加热器,以对挤压筒进行预热,防止由于温度应力而发生损坏,预热
800 tons aluminum rod profile extruder This machine is a new type of aluminum rod profile extrusion machine for aluminum or aluminum alloy bar and a variety of profiles extrusion. It is also possible to squeeze the pipe if a fixed mandrel is attached to the squeeze bar. This machine can be used flat die and cone die extrusion. The press is a three-column horizontal structure. Its main body consists of front beam, squeezing cylinder moving cylinder, extrusion chamber, column parts, moving beams, back beams and racks and other components. Extrusion chamber by the extrusion cylinder shell, heater, extrusion tube composed of three parts. Extruded tube is a combination of two layers of thick-walled tube with a hot-press fit, the inner diameter of the liner is φ120 mm, the extrusion tube shell is equipped with 10 electric resistance heaters with power of 3 ~ 4 kW, Preheat to prevent damage due to temperature stress, preheating
