The invention discloses a nitriding furnace for surfaces of drill rod head threads. The nitriding furnace comprises a furnace body, wherein a hearth with an opening in the upper end is arranged in the furnace body; a furnace tank with an opening in the upper end is arranged in the hearth in the length direction of the hearth; electric heating elements are arranged on two side walls of the hearth; a turnover support is hinged to one side of the furnace body in a turnover manner; a material frame is fixed to the turnover support; a plurality of drill rods are fixed on the material frame in parallel; and a furnace cover is hinged to one side of the furnace tank. According to the nitriding furnace for the surfaces of the drill rod head threads, the heat treatment nitriding process is optimized; an original vertical hoisting heat treatment nitriding mode is changed into a turnover inclined heat treatment nitriding mode; the nitriding furnace is simple in structure, ingenious in design and convenient to operate; the heat treatment nitriding efficiency of the drill rod head threads is improved; and meanwhile, the drill rods are prevented from being damaged in the heat treatment nitriding process.
Description
technical field [0001] The invention belongs to the manufacturing and processing technology of drill rods, in particular to a nitriding furnace for thread surface nitriding of drill rod heads. Background technique [0002] As we all know, during the processing of the drill pipe, it is necessary to carry out nitriding heat treatment on the thread surface of the head. In the traditional heat treatment and nitriding of drill pipes, many drill pipes are tied together with ropes, and then hoisted to process the drill pipes. However, this method is cumbersome, troublesome, and time-consuming. During the hoisting process of the bundled drill pipes, there will be collisions between the drill pipes, which will cause damage to the drill pipes and affect the quality of the drill pipes. Contents of the invention [0003] The object of the present invention is to provide a nitriding furnace for the thread surface of the drill pipe head, so as to solve the problems of cumbersome operat...
