Problems solved by technology

[0003] During foreign soft nitriding treatment, the workpiece is hung on the hook of the material rack, and then put into the nitriding furnace, such as figure 1 As shown, the material rack with the workpieces installed takes up a lot of space, so the amount of furnace loading each time is very small, and the production efficiency is greatly limited.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0015] As shown in the figure: the nitrocarburizing material frame of the bearing includes a barrel-shaped material frame 1, the side wall of the barrel-shaped material frame 1 and the bottom of the barrel all have air holes, and the top end of the side wall of the barrel-shaped material frame 1 is fixed with a Two or more hanging buckles 2 are provided with several layers of isolation nets 3 in the barrel-shaped material frame 1 .

[0016] The cross-section of the isolation net 3 is wave-shaped, which can ensure that the gas components in the furnace enter the barrel-shaped material frame 1 conveniently.

[0017] The hanging buckles 2 are evenly distributed on the top end of the side wall of the barrel-shaped material frame 1, and all the hanging buckles 2 are arranged at the same height.

[0018] The barrel-shaped material frame 1 includes a top ring body 1....

Abstract

The invention relates to a device for tufftriding of a loading bearing, in particular to a bearing tufftriding frame. According to the technical scheme provided by the invention, the bearing tufftriding frame comprises a barrel-shaped frame, wherein vent holes are formed on the side wall and the barrel bottom of the barrel-shaped frame; the top end part of the side wall of the barrel-shaped frame is fixedly provided with two or more than two suspension clasps; and a plurality of separation net layers are arranged in the barrel-shaped frame. The bearing tufftriding frame can effectively improve the charge batch for bearing tufftriding, so a bearing with the same charge batch occupies less space, and a nitrogenization furnace with the same capacitance can perform the tufftriding process of more bearings. Thus, the production efficiency is improved.

Description

technical field [0001] The invention relates to a device for loading bearings for nitrocarburizing treatment, in particular to a bearing nitrocarburizing material frame. Background technique [0002] Bearing soft nitriding is to heat the bearing parts to the temperature above the ACM line, and pass NH 3 With methanol gas, the N decomposed in the furnace 2 Combined with Fe of GCr15 bearing steel to form FeN alloy structure. The alloy structure has strong wear resistance, which can increase the service life of the bearing by more than 2 times. [0003] During foreign soft nitriding treatment, the workpiece is hung on the hook of the material rack, and then put into the nitriding furnace, such as figure 1 As shown, the material rack with the workpieces installed takes up a lot of space, so the amount of furnace loading each time is very small, and the production efficiency is greatly limited. Contents of the invention [0004] The purpose of the present invention is to ov...
