Thermal treatment device for metal

Abstract

The invention discloses a thermal treatment device for a metal. The device comprises a heating area, a discharging buffering area and a cooling area which are sequentially arranged, wherein the heating area comprises a heating furnace; the cooling area comprises a cooling device; the discharging buffering area comprises a discharging buffering device, and the discharging buffering device comprisesa protecting cover, and a guide mechanism which is arranged in the protecting cover; a buffering area feeding port and a buffering area discharging port are formed in the outer side of the protectingcover; the buffering area feeding port communicates with a discharging port of the heating furnace; the buffering area discharging port communicates with a feeding port of the cooling device; one endof the guide mechanism is connected to the buffering area feeding port, and the other end of the guide mechanism is connected to the buffering area discharging port. The thermal treatment device forthe metal is compact and ingenious in structure, high in reliability, and high in automation degree; the discharging buffering device is additionally arranged, so that outside cold air can be effectively prevented from directly entering the heating area, and as a result, the heat loss is decreased; the heat transfer between the heating area and the cooling area is avoided; the heating efficiency and the thermal treatment quality are improved; and moreover, the workpiece damage is reduced; and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to metal heat treatment equipment. Background technique [0002] Metal heat treatment is to heat a metal workpiece in a certain medium to a suitable temperature, and keep it at this temperature for a certain period of time, then cool it at a different speed, and control its performance by changing the surface or internal structure of the metal material. kind of craft. Heat treatment equipment is equipment for annealing, tempering, quenching, heating and other heat treatment operations on metal workpieces. The existing heat treatment equipment includes two working areas of heating and cooling. The metal workpiece is heated by the heating furnace, and then sent to the cooling area for cooling by the cooling equipment. After the metal workpiece is processed, it is sent out by the conveyor belt and directly from the discharge port. Dropped into finished product bin. [0003] W...

AI Technical Summary

Problems solved by technology

[0003] When the metal workpiece is transferred from the outlet of the heating furnace to the cooling equipment, the hot air in the heating furnace is output from the outlet of the heating furnace, causing heat loss, and the cold air from the outside and the cold air in the cooling equipment can easily When entering the heating furnace from the discharge port of the heating furnace, the heating efficiency in the heating furnace will be reduced, causing energy waste, and affecting the heat treatment effect of the metal workpiece, reducing the heat treatment quality and heat treatment efficiency

[0004] In the prior art, the height of the heating furnace is mostly higher than that of the cooling equipment. After the metal workpiece is heated, it cannot withstand a large impact force. Due to the height difference, the conveying device in the cooling zone directly falls onto the conveying device in the cooling zone and is impacted, so that the surface of the metal workpiece that has just been heated is damaged to a certain extent, which affects the process quality of the metal workpiece

When the metal workpiece is transported from the cooling area to the finished product warehouse, the metal workpiece is also vulnerable to damage due to the height difference between the cooling equipment and the finished product warehouse
