Automatic gantry-type composite heat treatment robot

Abstract

An automatic gantry-type composite heat treatment robot comprises a larger trolley (1), a smaller trolley (2), a movable gantry (3), a transmission mechanism (4), a movable beam (5) and a manipulator (6). The smaller trolley (2) capable of moving longitudinally is arranged on the larger trolley (1), and a middle post of the movable beam (5) arranged on the smaller trolley (2) is connected to the movable gantry (3) capable of moving vertically through the transmission mechanism (4). The automatic gantry-type composite heat treatment robot is characterized in that the manipulator (6) is mounted on the movable beam (5), the manipulator (6) grasps a workpiece to move longitudinally, transversely and vertically with the larger trolley (1), the smaller trolley (2) and the movable gantry (3) so as to implement rapid operations of feeding, grasping materials and quenching. According to the automatic gantry-type composite heat treatment robot, the manipulator (6) moves longitudinally, transversely and vertically with the larger trolley, the smaller trolley and the movable gantry so as to implement rapid operations of feeding, grasping materials and quenching effectively, and the temperature of product heat treatment in same furnace is constant basically.

Description

technical field [0001] The invention relates to a gantry type composite self-propelled heat treatment robot used for multiple heat treatment furnaces, material storage platform loading and unloading devices and rapid quenching. Background technique [0002] At present, the heat treatment of domestic long shaft, large and medium forgings, stainless steel solid solution, valves, rings, high manganese steel, high chromium steel and other workpieces is mostly heated by pit type, trolley furnace and turning trolley furnace. Carry out loading and unloading work with driving hoisting, or take out the furnace with a trolley, and then use driving hoisting to carry out loading and unloading work. This operation method has the following defects: the shaft furnace has first-out and then-quenching, and the quenching of shaft parts has high requirements for the plant and the foundation. It needs to reach 2.5 times the height of the highest part, and the cost of high-span plant and undergr...

AI Technical Summary

Problems solved by technology

This method of operation has the following defects: the pit furnace has first out and then quenching, and the quenching of shaft parts has high requirements for the plant and the foundation. It needs to reach 2.5 times the height of the highest part, and the cost of high-span plant and underground foundation is very high.

The trolley furnace cannot hoist the same batch of products at one time, and it needs to be hung manually, which is slow and low in work efficiency; moreover, the hoisting process is easy to cause the workpiece to swing and fall, and the safety performance is not high

Turning over the trolley can realize the rapid quenching of the workpiece as a whole, but there are many factors such as scratches and bruises on the workpiece, unsatisfactory circulation of the quenching pool after the workpiece enters the water, salvage of the workpiece, and charging of the hot furnace.

During the process of workpiece quenching and charging, the trolley furnace has serious heat loss in the heat treatment furnace, and the workshop environment is harsh. However, my country’s energy and environmental protection are facing great pressure, and the heating technology and equipment level of industrial furnaces are also facing great challenges.
