Auxiliary heat treatment drying oven for cast iron robot joint

Abstract

The invention discloses an auxiliary heat treatment drying oven for a cast iron robot joint. The auxiliary heat treatment drying oven for the cast iron robot joint comprises a box body, an air inlet pipe, an air blowing pipe and an air blower; a heating device and two layers of heat insulating walls are arranged on the inner wall of the box body; the heating device comprises an electric heating device and an infrared radiating heating device; the air inlet pipe and the air blowing pipe are respectively connected with an air inlet and an air outlet; the air inlet pipe is connected with an inertgas tank; a flow regulating valve is arranged on the gas inlet pipe; the air blowing pipe is connected with the air blower; an object carrying bracket is arranged on an inner wall surface; a temperature control module and a safety monitoring module are also mounted on the inner wall surface; and the heating device, the safety monitoring module, the temperature control module, the flow regulatingvalve and the air blower are all electrically connected with an external controller. According to the auxiliary heat treatment drying oven for the cast iron robot joint, cast iron is treated by fullyutilizing the conditions of the drying oven, and particularly, the influence of slow low-temperature heat treatment of the drying oven is reduced, so that annealing is refined, and possible adverse influence on a metal destressing process caused by a drying process is reduced.

Description

technical field [0001] The invention relates to the field of ovens, in particular to an auxiliary heat treatment oven for cast iron robot joints. Background technique [0002] Ovens are frequently used equipment in industry, including blast ovens, vacuum ovens, etc. Most of the existing ovens are equipped with a suction port and an air inlet casing, and heating elements are installed in the casing or on the side walls. The box is divided into several layers by a horizontal grid. The material tray containing the material is placed on the grid, the door is closed, the vacuum pump is used to evacuate, and then the heating element is started to heat the inside of the oven through heat radiation, and at the same time, the items in the oven Heating to achieve the purpose of drying. [0003] For cast iron, due to the nature of the metal itself, low-temperature stress relief annealing can occur at 500-575°C, and the temperature requirements are relatively low. In fact, it also ha...

Problems solved by technology

After forming, the robot joints need grinding, surface coating, drying and other steps. During drying, there is a certain temperature. Although the temperature of the special annealing process is relatively low, its impact is not negligible. Yes, because the oven is always running, it will have a certain impact on the metal material, and this impact is difficult to estimate
