Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment material racks, in particular to a combined rack that is easy to splice. Background Art

[0002] Carburizing refers to a chemical heat treatment process in which the steel parts are heated and kept warm in a carburizing medium to allow carbon atoms to penetrate into the surface layer in order to increase the carbon content of the steel surface and form a certain carbon concentration gradient. Carburized bearing steel has the characteristics of high strength, high toughness and high fatigue life.

[0003] Some equipment on the market generally achieves safe and stable operation and improves the service life of the entire material rack by setting pillars on the chassis, partitions and sleeves on the pillars, ribs and cross knots on the partitions, and setting the cross knots into a hollow cross structure.

[0004] However, when the above equipment is hoisted after carburizing, since the equipment and materials are in a suspended state, this may cause the combined frame to shake, which may cause collisions between the bearings, thereby affecting the shape of the outer surface of the bearing; in view of this, we propose a combined frame that is easy to splice.

[0009] Preferably, the size of the card block matches the size of the movable slot, and the size of the card block matches the size of the fixed block, so that the card block can be inserted into the fixed block.

[0010] Preferably, the size of the mounting piece is matched with the size of the mounting rod, and the mounting rod is sleeved inside the mounting piece, so that the mounting piece can move on the outer surface of the mounting rod.

[0014] Compared with the prior art, the utility model provides a combination frame that is easy to splice, having the following

[0015] Beneficial effects:

[0016] 1. In order to prevent the bearing from shaking too much when it is lifted after carburizing, the easy-to-assemble combined frame sleeves the bearing on the outer surface of the connecting rod, so that the upper surface of the limit block contacts the bottom of the bearing, and then aligns the clamping block with the movable groove to make the clamping block inserted into the movable groove.
