Embodiment 1

[0020] Example 1, such as Figure 1-2 As shown, the invention discloses a lifting and moving device for a forklift type ion nitriding furnace bell jar, comprising a lifting mechanism 1, a horizontal moving mechanism 2 and a horizontal track 6, and the lifting mechanism 1 is connected to the ion nitriding furnace bell jar through a hinge 3 The bottoms of 4 are connected, and the horizontal moving mechanism 2 moves in the horizontal track 6, and the horizontal track 6 is fixed with the base 7 of the ion nitriding furnace. The chassis 8 of the ion nitriding furnace is fixed on the base 7. In the working state, the bell jar 4 of the ion nitriding furnace is combined with the chassis 8, sealed by a sealing rubber ring, and the furnace is evacuated. An adjusting screw 5 is arranged between the top of the bell jar 4 and the lifting mechanism 1 for adjusting the verticality of the bell jar 4 to ensure the parallelism between the bell jar 4 and the chassis 8 . The front roller 9 of th...

Abstract

The invention discloses a forklift-type lifting and moving device of an ion-nitriding furnace bell jar. The forklift-type lifting and moving device of the ion-nitriding furnace bell jar comprises a lifting mechanism, a horizontal moving mechanism and a horizontal rail, wherein the lifting mechanism is connected with the bottom of the ion-nitriding furnace bell jar through a hinge, the horizontal moving mechanism moves in the horizontal rail, and the horizontal rail is fixed with a base seat of an ion-nitriding furnace. According to the forklift-type lifting and moving device of the ion-nitriding furnace bell jar, due to the fact that the maximum stress position is under the bell jar, the center of gravity is low, and lifting is stable. Due to the fact that the horizontal rail is fixed with the base seat of the ion-nitriding furnace, the self-weight and the relatively large area of the base seat of the ion-nitriding furnace can serve as a balance, and the bell jar can not topple when moving horizontally.

Description

technical field [0001] The invention relates to a lifting and moving device, in particular to a lifting and moving device for an ion nitriding furnace bell jar, which belongs to the field of heat treatment. Background technique [0002] Ion nitriding treatment is to place the workpiece to be nitriding in the vacuum chamber of the ion nitriding furnace, the workpiece is connected to the negative pole of the DC glow discharge power supply, and the bell jar is connected to the positive pole. Under the action of a DC electric field, the gas in the furnace undergoes glow discharge, and the generated nitrogen (positive) ions bombard the surface of the workpiece (cathode), and the workpiece is heated to the required nitriding treatment temperature (generally between 400 and 600 °C) ) At the same time, active nitrogen atoms penetrate into the interior of the workpiece, improving the hardness, wear resistance and corrosion resistance of the workpiece surface. [0003] At present, mo...
