A horizontal annealing furnace anti-swing device

Abstract

The invention discloses an anti-swing device for a horizontal annealing furnace. The vacuum annealing furnace comprises an outer cover, a heating element, a travelling part and a furnace liner, wherein the furnace liner is connected between the outer cover and the traveling part; the traveling part is connected on a track device to move left and right by virtue of a transmission device; the heating element is connected in a vacuum cavity to heat the vacuum furnace, at least one group of anti-swing devices are symmetrically connected on two sides of the travelling part of the annealing furnace, each anti-swing device comprises a connecting part, at least one roller and a bracket, and the upper end of each connecting part is attached to the bottom of the furnace liner while the lower end of each connecting part is pressed on the at least one roller; the bracket is used for fixedly connecting the roller on the traveling part; a double-lug bush is further connected between each roller and a shaft, and the connecting part is pressed between two lugs of the double-lug bush. According to the anti-swing device disclosed by the invention, the left and right separated horizontal annealing furnace is reduced or avoided, so that the annealing treatment quality and the annealing treatment efficiency of parts which are placed in the annealing furnace are improved.

Description

technical field [0001] The invention relates to the field of vacuum annealing furnace and technology, in particular to an anti-swing device for a horizontal annealing furnace. Background technique [0002] Existing vacuum annealing furnaces, especially horizontal vacuum annealing furnaces, due to the requirements of sealing performance and heat preservation performance, are divided into two sides of the furnace cover, which has the advantage of saving space. The sealing position is at the top of the vacuum furnace, and it is a butt joint. When the vacuum annealing furnace is used, it is inconvenient to observe and timely plug the leakage. Time to get high quality annealed parts. [0003] Therefore, we try to use a horizontal vacuum annealing furnace, especially in the heating annealing process of the vacuum furnace for titanium and titanium alloy blanks in a vacuum state, using a vacuum annealing furnace separated from the left and right, which will lead to A larger swing ...

Problems solved by technology

[0002] Existing vacuum annealing furnaces, especially horizontal vacuum annealing furnaces, due to the requirements of sealing performance and heat preservation performance, are divided into two sides of the furnace outer cover, which has the advantage of saving space. The sealing position is at the top of the vacuum furnace, and it is a butt joint. When the vacuum annealing furnace is used, it is inconvenient to observe and plug the leakage in time. Time to get high quality annealed parts

[0003] Therefore, we try to use a horizontal vacuum annealing furnace, especially in the heating and annealing process of the vacuum furnace for titanium and titanium alloy blanks in a vacuum state, using a vacuum annealing furnace separated from the left and right, which will lead to A large swing will be generated, which will cause wear on the inner tank of the vacuum furnace, and will also cause frictional damage to the parts that are placed in the vacuum furnace to be processed or have been processed, causing the surface wear of some parts and reducing their quality.
