以Φ150×10000×1/75型电杆为例,作一介绍。一、锚固夹具大头锚固盘由25毫米厚的45号钢钢板经车削、钻孔、正火后,焊上四个爪子制成,其圆径比钢模大头大30毫米(见图1)。小头锚固盘选用45号钢钢板,经车孔(小头加料)、铣T形槽(张拉和连接排气咀用)、车梯形螺纹、钻孔、正火加工制成(见图3)。选用小头锚固盘后,电杆长度相应短了,所以按不同杆型在钢模小头须加长30～50毫米(按冷拔低碳
Take Φ150 × 10000 × 1/75 type pole as an example, as an introduction. First, the anchoring fixture large head anchor plate is made of 25 mm thick 45 steel plate after turning, drilling, normalizing, welding four claws, its diameter larger than the steel die big head 30 mm (see Figure 1). The small anchor plate is made of steel plate No. 45, and is made by the hole (small head feeding), milling T-shaped groove (for tensioning and connection exhaust nozzle), trapezoidal thread, drilling, and normalizing (see Figure 3). ). After selecting the small anchoring plate, the length of the pole is correspondingly shorter, so the length of the steel die must be lengthened by 30 to 50 millimeters according to different types of rods (according to cold drawing low carbon
