Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 In the described embodiment, a pick includes a tooth shank 3, a tooth body 2 and a tooth head 1. The material of the tooth shank 3 is 42 Molybdenum steel, the material of the tooth body 2 is H13 steel, and the material of the tooth head 1 is It is cemented carbide, the tooth shank 3 and the tooth body 2 are fixedly connected by friction welding, and the tooth body 2 and the tooth head 1 are fixedly connected by friction welding.
[0038] Such as figure 1 As shown, the shape of the tooth body 2 is a truncated cone, one side of the tooth body 2 is provided with a mounting groove matching the tooth head 1, the tooth head 1 is fixed in the mounting groove, and the other side of the tooth body 2 is fixedly connected with the tooth handle 3 , the area of one side of the tooth body 2 is smaller than the area of the other ...

The invention discloses a pick, a pick production process and a pick production device, and aims to provide a pick, a pick production process and a pick production that can perform simultaneous welding and simultaneous heat treatment on three parts of the pick device. It includes a tooth shank, a tooth body and a tooth head. The material of the tooth shank is 42 Molybdenum steel, the material of the tooth body is H13 steel, and the material of the tooth head is hard alloy. The tooth shank and tooth The tooth body is fixedly connected by friction welding, and the tooth body and tooth head are fixedly connected by friction welding. The beneficial effects of the present invention are: through the way of friction welding, the welding of the tooth head and the tooth body and the welding of the tooth shank and the tooth body can be well guaranteed at the same time; by adding the induction coils corresponding to the three parts, the cutting The three parts of the tooth are heated to their most suitable temperature for heat treatment at the same time; the cooperation of the additional rotating rod and connecting rod guides the movement of chuck one and chuck two.
Description
technical field [0001] The invention relates to the technical field related to picks, in particular to a pick, a production process for a pick and a production device for a pick. Background technique [0002] Picks are divided into shearer picks and roadheader picks. They are the key components of large shearers and roadheaders. They are mainly composed of tooth shanks, tooth bodies and tooth heads. They are mainly used in coal mining and roadway excavation in coal fields. In mining fields such as mining, with the increasing demand for resources, large-scale mining machinery is used more and more widely, so higher requirements are put forward for the performance of mining picks. Generally, the tooth shank and the tooth body are welded first by brazing. Together, the tooth head is welded to the tooth body. [0003] The traditional brazing method cannot simultaneously weld the three parts of the pick, and because the materials of the three parts of the pick are different, the...
