SUMMARY
[0004] To solve the above problems, the utility model discloses a material rack device for bar heat treatment loading process uses, and it is stable frame structure, can keep stability before and after heat treatment, hoist convenient, can be repeatedly used.
[0005] A kind of bar annealing material rack device, including main frame, main frame is equipped with several horizontal rods in sequence;Each described horizontal rod is connected with the reinforcing rib one of welding portion of the main frame;The bottom of the main frame is equipped with positioning block every end and the top is equipped with positioning slot every end;The left and right ends of each described horizontal rod are evenly arranged with lifting lug.
[0006] Further, wherein main frame is sequentially stacked upwards, wherein the positioning block on the main frame located in upper layer and the positioning slot on the main frame located in lower layer are mutually clamped and matched, facilitate sequentially stacked upwards.
[0007] Further, main frame and horizontal rod are all adopted square steel, and material quality selects 0Cr18Ni9.
[0008] Further, one end of positioning block is fixedly welded with reinforcing rib two.
[0009] The rod material to be bundled will be placed in the rack device; the whole crane is hoisted to load the main frame; placed on the annealing furnace trolley; the main frame of the second layer is aligned and positioned in the clamping groove, and then stacked on the main frame of the first layer, and so on until full; after the heat treatment is completed, the trolley is opened. The crane directly hoists the main frame layer by layer, and the whole annealing process is completed.
[0010] The beneficial effects of the utility model are: convenient hoisting, improved loading efficiency, more stable rod material stacking, ensured straightness of the rod material after annealing, improved annealing temperature uniformity by leaving a certain gap between the upper and lower layers, met various quality requirements of products, and ensured sufficient furnace loading.
