Problems solved by technology

[0002] The vacuum atmosphere furnace is mainly used for product welding. Putting the product directly into the furnace will cause problems such as uneven heat conduction, surface damage, and local deformation of the product. Processing residues will also be left in the furnace, which is not conducive to product placement and Cleaning of the working face, which will further lead to more serious quality problems

Embodiment Construction

[0018] The tooling is a box body, including air outlet pipe 1, front plate 2, hexagon socket head screw 3, rear plate 4, upper plate 5, lower plate 6, left side plate 7, slotted pan head screw 8, hex nut 9 , right-angle plate 10, intake pipe 11, right side plate 12. The bottom of the hearth of the vacuum atmosphere furnace is an air inlet, on which is a thermocouple, corresponding to the two small holes on the back plate 4 of the tooling box, one of which is inserted into the thermocouple, and the other hole is connected to the air inlet pipe 11 and the air inlet . In this way, the thermocouple is equivalent to entering the inside of the tooling box, and can directly control the temperature increase; and the air intake pipe 11 guides the cold air inside the air intake hole into the inside of the tooling box, and then passes through the small opening 13 on the air inlet pipe 11, The cold air is evenly filled inside the box to achieve the purpose of controlling the temperature ...

Abstract

The invention discloses a welding protection tool for a vacuum atmosphere furnace and belongs to the technical field of machining. The welding protection tool mainly comprises a furnace-in heating part, a circulating cooling part, a product protecting part and a sealing part. The furnace-in heating part is mainly distributed near a thermocouple and used for controlling rising of the temperature in the tool. The circulating cooling part surrounds the edge of the tool and the top of the tool and used for reducing of the temperature in a furnace hearth. The product protecting part is located on the bottom of the furnace hearth and carries out different treatments on different products and receives product residues. The sealing part is an auxiliary control link for the change of the temperature in the furnace hearth. According to the welding protection tool for the vacuum atmosphere furnace, by means of the structure that an air inlet pipe surrounds the edge of the interior of a tool box body by a circle, cold air is evenly and fully distributed in the box body so that the temperature can be reduced at a constant speed, and the quality problems such as product deformation caused by the large change of the temperatures of regions are avoided. Fine holes are evenly distributed in the periphery, in the direction back onto the products, of the air inlet pipe, and in this way, the surface damage problem caused when cold air directly blows the products is avoided.

Description

technical field [0001] The invention relates to a welding protective frock for a vacuum atmosphere furnace, which belongs to the technical field of processing. Background technique [0002] The vacuum atmosphere furnace is mainly used for product welding. Putting the product directly into the furnace will cause problems such as uneven heat conduction, surface damage, and local deformation of the product. Processing residues will also be left in the furnace, which is not conducive to product placement and The cleaning work of the working face will further lead to more serious quality problems. Contents of the invention [0003] The invention is a welding protection tool for a vacuum atmosphere furnace. The purpose is to use this type of vacuum atmosphere furnace to meet the quality requirements of products faster and better, and to improve the service life of the equipment. [0004] The purpose of the present invention is achieved through the following technical solutions:...
