Hook tail frame hot working tool

Abstract

The invention relates to the technical field of coupler yoke machining, and discloses a coupler yoke hot machining tool which comprises a fixing arm, a fixing rod and a supporting rod. The top end of the fixed rod is connected with the fixed arm; the fixing rod comprises a left fixing rod and a right fixing rod which are vertically arranged on the left side and the right side of the fixing arm; the interval between the left fixing rod and the right fixing rod is smaller than the length of an inner cavity of the coupler yoke to be hoisted. The left fixing rod and the right fixing rod can penetrate through an inner cavity of a coupler yoke to be hoisted at the same time, and protrusions for preventing the supporting rod from falling are arranged at the bottom of the left fixing rod and the bottom of the right fixing rod. The supporting rod is detachably arranged on the protrusion and can make contact with the bottom face of the coupler yoke to be hoisted so as to bear and support the coupler yoke. The lifting device is simple in overall structure, convenient to use, capable of stably lifting a large batch of coupler yokes at a time and beneficial to improving the hot working efficiency.

Description

technical field [0001] The invention relates to the technical field of hook tail frame processing, in particular to a hook tail frame thermal processing tool. Background technique [0002] The coupler frame is an important part of the coupler buffer device on the railway vehicle. It is used to assist the connection of the train carriages, form the train transportation and transmit the traction force, and plays a key role in the normal operation of the railway vehicle. There are mainly three series of products of type 13, type 16 and type 17 for the coupler frame used in the coupler and buffer device of railway freight cars. Here we take Type 13 as an example to illustrate the structural features of the existing hook-tail frame. The overall structure of the hook tail frame is shown in the attached figure 1 , the hook-tail frame itself has a relatively irregular structure and is a frame structure. Specifically, it is a hollow frame body with a long cross-section; the upper ...

Problems solved by technology

However, limited by the rigidity of the round pipe itself, a round pipe with a length of 2m can only lift 5 pieces of 13-B type hook tail frames at a time, and the single transfer volume is small, and the transfer period of each furnace hook tail frame is relatively short. In addition, because the circular pipe first requires the coupler pin holes of multiple coupler frames to be in the coaxial state, it takes a long time to adjust the position when stacking coupler frames, resulting in stacking of coupler frames. Coding efficiency and transfer efficiency are both low, which greatly affects the thermal processing efficiency of the coupler frame
