The crosspiece is supported by the two lower sheaths and guided by the upper and lower guides. The punch container crosspiece contains a punch container insulation system (insulating material and wall in stainless steel). The shear used to detach the base plate from the front of the die is mounted on top. The punch container holder houses the punch container, the latter prising three parts called skirt, intermediate bushing and bushing. The punch container is supported and centred by three keys and it is axially secured by a sturdy split ring hinged to the crosspiece. Alignment of the punch container holder crosspiece is controlled with a reference scale and analogue output inductive sensors. The punch container is heated by internal electrical heaters arranged in such a way as to divide it into four heating areas each with its own thermocouple.6）擠壓筒構(gòu)架——擠壓筒圖N176。 212613001A這個焊接的鋼構(gòu)件的軸向運動由四個與擠壓側(cè)梁連接的液壓油缸控制。此側(cè)梁由兩個低位護套支撐，并由上部和下部導向進行導向。擠壓筒沖擊梁包含擠壓筒絕緣系統(tǒng)（絕緣物質(zhì)和不銹鋼圈），用于基座從模具前面分離的飛剪被安裝在頂部。擠壓筒被擠壓筒構(gòu)架覆蓋保護。后者包括三個部分，分別叫做護裙、中間軸套、軸套。擠壓筒由三個關(guān)鍵部件支撐和對齊中心。它的軸向方向由一個與側(cè)梁鉸接的帶缺口的圓環(huán)來確保。擠壓筒構(gòu)架的對中由一個參考刻度來控制。同樣的情況也發(fā)生在產(chǎn)量感應傳感器。擠壓筒通過內(nèi)部的電加熱器來加熱，整個擠壓筒分為四個加熱區(qū)，每個加熱都帶有自己的加熱偶。7) Shear Drawing N176。 212615001A The shear is secured on top of the container holder crosspiece with a key and relative bolts. It prises a blade carrier slide manded by an oil hydraulic cylinder sliding along a guide structure, with bronze sliding blocks, fixed to the support integral with the crosspiece. A sleeve ejector is secured integral to the ram. 8) Side cylinders – Drawing N176。 212616001A The stems of these doubleacting cylinders are connected to the mobile crosspiece。 they provide the rapid forward and return stroke of the mobile crosspiece and add their thrust force to that of the master cylinder during the extrusion phase. 9) Container cylinders – Drawing N176。 212617001A The four container cylinders, used to close the container crosspiece, provide elevated clamping and axial translation force.7）壓余剪圖N176。 212615001A 壓余剪被用一個銷子和相連的螺栓可靠地安裝在擠壓筒構(gòu)件的頂部。它包括一個被液壓油缸控制的滑動刀架，刀架沿導向裝置滑動。以及一個被固定在構(gòu)件梁支撐架上的青銅滑塊。一個套筒式排出器被安裝在擠壓頭上。8）側(cè)缸圖N176。 212616001A 這些雙向作用的液壓缸的活塞桿與移動梁相連接。它們提供移動快速前進和后退的行程，并在擠壓階段增加主缸的推力。9）擠壓筒缸圖N176。 212617001A 四個擠壓筒缸通常圍繞著擠壓筒，提供高的夾緊力和軸向位移力。10) Billet loader Drawing N176。 212618001A The billet loader is of the horizontal “Shuttle” type. Linear movement is provided by a variablespeed electric motor and controlled by an encoder. The mobile head allows an oil hydraulic pusher to insert the billets directly into the hole of the container (the speed of the pusher is controlled by a proportional valve). The billet slides along a roller conveyor in order to reduce heat dispersion and friction. The mobile head runs along lowfriction highcapacity linear bearings.10）上錠機圖N176。 212618001A 上錠機是水平穿梭型，由一臺變速電動機提供其直線運動的動力，并由編碼器控制。移動頭允許液壓推桿將鑄錠直接推入擠壓筒的孔內(nèi)（推桿的速度由定量閥控制）。為了減少熱損失和摩擦力，鑄錠沿著滾道滑動。移動頭裝有低摩擦、高承受力的線性軸承。11) Die recirculation Drawing N176。 212622001A A device located next to the press recirculates the cavities (max. 3) on a special trolley plete with brackets for securing the cavities. The trolley moves both lengthways and sideways to simplify inspection and the manual replacement of the cavities. Movement is provided by oil hydraulic motors and a planetary gear , with rack and pinion.11）模具的循環(huán)使用裝置圖N176。 212622001A 擠壓機循環(huán)使用模具的模座（最多3個）安裝在一個特別的臺車上，它的旁邊有一個保護它的支架。臺車能沿著縱向和側(cè)向移動，可簡單觀察其工作情況并手工更模座。動力由液牙馬達提供，并裝有一臺帶行星齒輪的減速機。12) Oil hydraulic pumps located on the ground, acoustically insulated with a soundproof cabin (optional).
