Description

Technical field:

[0001] The invention relates to the technical field of annealing material frames, and more particularly to a stacking and carrying device for preventing ferrules from annealing and deformation. Background technology:

[0002] In the annealing furnace, the workpiece is placed in a material frame, and then the material frame enters the annealing furnace for annealing treatment; the current workpieces (for bearings, the workpieces mainly refer to bearing rings) generally need to be neatly stacked and stacked in the material frame. The conventional method is to place the workpieces adjacent to each other in the material frame, but when the material frame is annealed, the workpieces will be deformed. Then, by adjusting the position of the workpiece, a gap is set between adjacent workpieces in the same plane, which can effectively improve the deformation; but in actual operation, the material frame is generally placed on the ground, and the workpieces are manually stacked in the material frame, and then hoisted to the conveyor line on the annealing furnace. However, during the hoisting process, the problem of the tilting of the material frame cannot be avoided, and the tilting of the material frame will cause the workpiece to move, causing the adjacent workpieces to be against each other again, especially the conical rings, and the stacked rings are prone to collapse during hoisting; so currently, the material frame is set on the conveyor line on the annealing furnace, and then the workpieces are stacked; but because the material frame itself has a certain height, and the annealing furnace raises the position of the material frame, the stacking of the workpieces is very inconvenient;

[0003] Moreover, the current annealing furnace includes a rectangular base, side baffles are welded and fixed on all sides of the base, adjacent side baffles are welded together and columns are welded and fixed, and the lower bases of the columns are welded and fixed together. However, the annealing furnace is repeatedly put in and out of the annealing furnace. After long-term use, the welds of the bottom plate of the side baffles are detached due to repeated heating, and frequent repair welding is required. If the number of repair welding is too many, the furnace can only be scrapped. Therefore, it is necessary to design a material stacking frame structure that is convenient for stacking and has a long service life. Summary of the invention:

[0004] The purpose of the present invention is to address the deficiencies of the prior art and to provide a stacking and carrying device for rings to prevent annealing deformation. The device facilitates the stacking of rings and can effectively separate the stacked workpieces, thereby achieving air flow in the material frame and reducing the occurrence of annealing deformation; and the material frame has a long service life.

[0031] The core tube 221 is sleeved with a plurality of stacked conical rings 4, and the top surfaces or bottom surfaces of the upper and lower adjacent conical rings 4 are against each other; that is, the conical rings 4 are stacked in an upper and lower positive and negative manner, and when the conical rings 4 are placed positive and negative, the airflow resistance in the annealing frame 1 is less;

[0039] A plurality of flow holes 111 penetrating the positioning ribs 14 are formed in an array on the lower end surface of the bottom plate 11 . The flow holes 111 are distributed between adjacent stacking columns 22 . Airflow can enter the annealing frame 1 through the flow holes 111 and the positioning holes 211 .

[0040] Two channel steel bottom longitudinal beams 15 are fixedly connected to the lower end surface of the bottom plate 11, and the front and rear ends of the bottom longitudinal beams 15 extend out of the positive baffle 13 and are formed with chamfers; based on the bottom longitudinal beams 15, the annealing material frame 1 can be transported by a forklift;

[0043] Working principle: This solution is a stacking and carrying device, which is mainly composed of two parts: annealing frame 1 and stacking hanger 2.

[0044] The annealing frame 1 uses a positioning rib plate 14, a reinforcement angle iron 17, a support plate 18, a bottom longitudinal beam 15 and a hanging beam 16 to improve the strength of the annealing frame 1. The positioning rib plate 14 can reinforce the bottom plate 1 and the side rib 12, and the bottom longitudinal beam 15 and the hanging beam 16 can reinforce the bottom plate 1 and the positive rib 13; at the same time, it is convenient to hoist the annealing frame 1, and can effectively improve the service life of the annealing frame 1;

[0045] The stacking hanger 2 can be installed with a ring (including a conical ring 4) in the stacking column 22 by removing the horizontal top beam 25. During the placement process, there is no problem of adjacent rings on the left, right, front and back abutting against each other. At the same time, it can be operated on the ground, which is convenient for the stacking operation. After the stacking is completed, the stacking column 22 is clamped with the horizontal top beam 25, and then lifted to the annealing frame 1. The positioning rib plate 14 is used to position the stacking hanger 2 in the annealing frame 1, so that the side opening 121 is directly opposite to the limit horizontal axis 22.

[0046] Then the annealing frame 1 is hoisted onto the conveyor line of the annealing furnace. During the hoisting process, the stacking column 22 can limit the displacement of the ring. When the annealing frame 1 is on the annealing furnace, the stacking column 22 of the stacking hanger 2 can be hoisted away from the annealing frame 1 by withdrawing the limit horizontal axis 2, so that the ring is transferred to the annealing frame 1, and annealing treatment can be carried out. At this time, the air in the annealing frame 1 is easy to circulate, and the workpiece is not easy to be deformed due to uneven heating.

Any person skilled in the art may modify the embodiments without violating the spirit and scope of the present invention, and therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
