Embodiment Construction
[0020] The technical solution of the present invention will be described in detail below in conjunction with specific embodiments.
[0021] The wear-resistant tooth tip of the present invention is processed by the following method:
[0022] ①Tooth blanking→②Forging→③Machining→④Tooth head fusion welding wear-resistant alloy→⑤Grinding tooth tip→⑥Heat treatment of tooth body→⑦Surface anticorrosion treatment.
[0023] The specific implementation of above-mentioned operation is:
[0024] ①Tooth blanking: Alloy structural steel rods are selected as raw materials, and the blanking volume is calculated according to the volume of the pick blank;
[0025] ②Forging: According to the forging temperature of the selected alloy structural steel, hot forge the tooth body blank;
[0026] ③Mechanical processing: Cut out the shape of the tooth body on the lathe according to the drawing requirements;
[0027] ④ Welding wear-resistant alloy at the head of the tooth: In the center hole at the to...
