Iron backing plate for track and multi-station and multi-direction extrusion forming die and forming method of iron backing plate
The invention discloses an iron backing plate for a track and a multi-station multi-directional extrusion forming die and a forming method thereof, the backing plate is integrally forged and formed by a Q235 rolled steel plate, and the die comprises a first multi-directional extrusion procedure die set, a second punching procedure die set and a third burr finishing procedure die set which are linearly and sequentially arranged; the forming step comprises the steps of plate blanking, multi-directional extrusion forming through the first multi-directional extrusion procedure die set, punching through the second punching procedure die set and burr finishing through the third burr finishing procedure die set. Different from a nodular cast iron iron base plate produced through a traditional casting process for rail transit, the novel iron base plate product for rail transit is completely different from an existing cast iron base plate in material and production process, the novel base plate adopts a Q235 plate as a blank, a metal flow line generated by rolling of the plate is reserved for a formed product, and the production efficiency is improved. A product matrix is a forged structure, the overall performance of the product is superior to that of a cast iron base plate, and high-speed and heavy-load rapid development of a railway system is effectively supported. According to the novel iron base plate, the multi-station and multi-direction extrusion forming technology is adopted, the plate is subjected to the three-station continuous forging forming process, qualified forge piece products are directly formed, the automation degree is high, compared with a traditional casting production mode, the number of production processes is small, the production efficiency is greatly improved, and the production cost is low. The production process is short, the automation degree is high, production raw materials are easy to obtain, and the order requirements of customers can be met in time.
本发明公开了一种轨道用铁垫板及其多工位多向挤压成形模具及其成形方法，垫板由Q235材质扎制钢板一体锻造成型，模具包括直线依次排布的第一多向挤压工序模具组、第二冲孔工序模具组和第三精整毛刺工序模具组；成形步骤包括板材下料、第一多向挤压工序模具组多向挤压成形、第二冲孔工序模具组进行冲孔、第三精整毛刺工序模具组进行精整毛刺；区别于传统的铸造工艺生产的球墨铸铁轨道交通用铁垫板，本发明的新型的轨道交通用铁垫板产品的材质和生产工艺完全不同于现有铸造铁垫板，新型垫板采用Q235材质板料为坯料，成形产品保留了板料轧制产生的金属流线，产品基体为锻造组织，其整体性能优于铸造铁垫板，有效支持了铁路系统高速、重载的快速发展。本发明的新型铁垫板采用了多工位多向挤压成形工艺，板料经过三个工位的连续锻造成形工序，直接成形出合格的锻件产品，自动化程度高，对比传统铸造生产方式的生产工序少，生产效率大大提高，生产成本低。由于本发明的生产工序短，自动化程度高，生产原材料易于获得，可以及时满足客户对订单需求。
