Carrying device used for carrying bars away from quenching bath

Abstract

The invention relates to a carrying device used for carrying bars away from a quenching bath. The carrying device comprises a main body frame. A spindle is mounted on the upper portion of the main body frame and connected with a motor. A first pulley and a second pulley are mounted on the spindle in sequence. A mooring rope is mounted on the second pulley. A main lifting frame is tied to the lower end of the mooring rope. A ball screw is mounted on the lower portion of the main lifting frame and connected with the motor. A smooth rod is fixedly mounted on the upper portion of the main lifting frame. Two leg frames are slidably mounted on the smooth rod. A clamping opening is formed in the lower end of each leg frame. The carrying device is ingenious in structure and can automatically clamp and release the bars while driving the bars to do lifting movement through belt transmission and incomplete gear steering functions under the conditions of motor drive and belt tensioning due to spring extrusion, and the effect of carrying the bars away from the quenching bath through convenient and rapid operation and control mode is achieved.

Description

technical field [0001] The invention relates to a carrying device, in particular to a carrying device for moving bars away from a quenching pool. Background technique [0002] The traditional quenching is to heat the steel to the temperature above the critical temperature of Ac3 hypoeutectoid steel or Ac1 hypereutectoid steel, keep it warm for a period of time to make it fully or partially austenitized, and then quickly cool it to The heat treatment process of isothermally transforming martensite or bainite below Ms or near Ms. Before quenching, the general steel bars need to be put into the quenching pool to pick up the quenching liquid. Generally speaking, after the bar is completed After dipping the quenching liquid, it is necessary to use corresponding equipment to automatically clamp the bar from the quenching pool, lift it and then release it to complete the handling work after dipping, but the traditional mechanical device is used to move the bar out of the quenching ...

Generally speaking, after the bar is completed After dipping the quenching liquid, it is necessary to use corresponding equipment to automatically clamp the bar from the quenching pool, lift it and then release it to complete the handling work after dipping, but the traditional mechanical device is used to move the bar out of the quenching pool. When it is necessary to manually assist a large number of control operations, it is very inconvenient
