Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of cold drawing machines, in particular to a mechanical feeding type steel pipe processing cold drawing machine. Background Art

[0002] The cold drawing production process is mostly adopted in the production of steel pipes. A cold drawing machine is required in the cold drawing process. For example, a mechanical feeding type seamless steel pipe processing cold drawing machine disclosed in Chinese patent application number CN202121420904.1 has the following specific contents: when using the cold drawing machine to perform cold drawing operation on seamless steel pipes, first, multiple seamless steel pipes are laid flat on the surface of the material table, and then the seamless steel pipes abutting against the stop rod are pushed up by the lifting assembly and the pushing plate until the seamless steel pipes are raised above the stopper and slide into the guide rod, and then slide down along the guide rod to the feeding track, and then the feeding track is started to feed the seamless steel pipe into the machine body, and the machine body is started to perform cold drawing operation on the seamless steel pipe, completing the automatic loading of the seamless steel pipe. It has the following technical problems:

[0003] The seamless steel pipe is pushed upward by the pushing plate, so that the seamless steel pipe slides along the guide rod to the track. When the seamless steel pipe is limited by the stop rod and the seamless steel pipe contacts the pushing plate at the same time, the pushing plate can push the seamless steel pipe upward. When the diameter of the seamless steel pipe is greater than the width of the pushing plate, the seamless steel pipe is limited by the stop rod, and the pushing plate cannot contact the seamless steel pipe, so that when the pushing plate moves upward, the seamless steel pipe is pushed away from the stop rod, and the seamless steel pipe cannot be pushed to one end of the guide rod. When the diameter of the seamless steel pipe is smaller than the width of the pushing plate, multiple seamless steel pipes will roll and accumulate to the upper end of the pushing plate. Therefore, the pushing plate cannot push seamless steel pipes of different diameters to move upward one by one. Utility Model Content
