Hoisting device with self-adaptive supplement structure for metal heat treatment

Abstract

The invention discloses a hoisting device with a self-adaptive supplement structure for metal heat treatment, and belongs to the field of metal heat treatment. According to the hoisting device with the self-adaptive supplement structure for metal heat treatment, a clamping part is installed on the inner wall of an annular frame to clamp the outer wall of a cylindrical iron ingot, so that the covered area during iron ingot fixing is effectively reduced; iron blocks are hoisted through the device instead of being directly stacked for heat treatment, so that the bottom of the iron ingot is effectively prevented from being covered by the contact surface when the iron ingot is placed, and the heating uniformity of the iron ingot during heat treatment is further guaranteed; through fixed connection of a clump weight and a sliding bar, power is provided for movement of the sliding bar by means of the gravity of the clump weight, so that a first clamping arm and a second clamping arm can deform in a self-adaptive manner to keep firm clamping of the iron ingot, the situation that hoisting and clamping of the iron ingot are loosened due to expansion and contraction of the iron ingot is avoided, and the using stability and safety of the device are effectively guaranteed.

Description

technical field [0001] The invention relates to the field of metal heat treatment, and more specifically relates to a metal heat treatment lifting device with an adaptive supplementary structure. Background technique [0002] Metal heat treatment is a metal treatment process that heats the metal to an appropriate temperature, and then performs heat preservation and cooling operations. Through the heat treatment operation of the metal, the surface or internal microstructure characteristics of the metal can be effectively changed, making the metal more suitable for its use. Environment, among them, iron material is one of the most widely used metal materials in production and life today, and its heat treatment process is relatively mature. [0003] In today's technology, when the iron material is heat treated, the whole piece of iron material is usually stacked directly inside the heating furnace. The ground cover affects the heating efficiency of the bottom of the iron ingot...

Problems solved by technology

[0003] In today's technology, when the iron material is heat treated, the whole piece of iron material is usually stacked directly inside the heating furnace. Covering the ground affects the heating efficiency of the bottom of the iron ingot, making the bottom of the iron ingot heated unevenly, resulting in a decrease in the heat treatment efficiency of the iron ingot
