Description

Technical Field

[0001] This utility model relates to the field of valve steel processing technology, and in particular to a convenient rack for placing annealed valve steel bars. Background Technology

[0002] Annealing is a crucial and essential processing step in the production and processing of valve steel bars. During annealing, the valve steel bars need to be placed on a separate rack. The existing racks are stacked frames, where multiple valve steel bars are laid flat or sometimes stacked. This results in different valve steel bars sticking together, making them relatively inconvenient to handle. Furthermore, the limited space between adjacent valve steel bars during annealing leads to relatively low annealing efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a convenient rack for annealing valve steel bars. It can be used in conjunction with a support plate in the width direction of a placement frame. During use, the valve steel bars can be directly placed on this rack, allowing for sufficient space on one side of the placement area. This improves airflow and annealing efficiency. The side space facilitates easy handling with clamping tools, enhancing usability. Furthermore, the rack's width is greater at the top than at the bottom, minimizing the space occupied on both sides and making placement more convenient.

[0004] The technical solution of this utility model is as follows: A convenient annealing rack for valve steel bars is characterized by comprising an arc-shaped main body placement frame made of stainless steel with an upward opening. The upper end of the main body placement frame is an upward-opening main body placement area. The lower end of the main body placement area is provided with an upward-protruding placement limiting engagement boss. The placement limiting engagement boss is formed by pressing the lower outer side of the main body placement frame upward. The front and rear sides of the upper end of the main body placement frame are respectively provided with mounting and placement plates facing the front and rear directions. The projection of the mounting and placement plates in the front and rear directions is an arc-shaped structure. The left and right sides of the main body placement frame are respectively provided with symmetrical and inclined safety ramps facing the upper and outer sides in the left and right directions. The interior of the main body placement area is formed with a first placement groove and a second placement groove on the left and right sides of the placement limiting engagement boss.

[0005] Furthermore, the width of the mounting plate in the left-right direction is the same as the width of the upper end of the main body mounting frame in the left-right direction.

[0006] Furthermore, the upward protrusion of the placement limiting boss is tilted towards the front or tilted towards the rear.

[0007] Furthermore, the lower end of the main body placement and fitting frame is located below the placement limiting fitting boss to form a reinforced support fitting spare groove.

[0008] Furthermore, the width of the lower end of the main body placement and fitting frame in the left-right direction is greater than half the width of the upper end of the main body placement and fitting frame in the left-right direction.

[0009] The beneficial effects of this utility model are: This utility model can be used in conjunction with a support plate in the width direction of a frame. During use, valve steel bars can be placed directly on this convenient rack, allowing for sufficient space on one side of the placement position. This improves airflow and increases annealing efficiency during annealing. The side space also facilitates easy handling with clamping tools, enhancing usability. Furthermore, the width at the top is greater than at the bottom, minimizing the space occupied on both sides and making placement more convenient. Attached Figure Description

[0011] like Figures 1 to 7As shown, a convenient annealing rack for valve steel bars includes an arc-shaped main body placement frame 1 made of stainless steel with an upward-facing opening. The upper end of the main body placement frame 1 is an upward-facing main body placement area, where the valve steel bars are placed during use. A protruding placement limiting boss 2 is provided at the lower end of the main body placement area of ​​the main body placement frame 1. This boss separates the main body placement area of ​​the valve steel bar into two areas. During use, the bar is placed in one area, while the other side remains open. This ensures better airflow on one side and provides more space for retrieval, making the handling and fitting operation easier and more convenient. The placement limiting boss 2 is formed by pressing an upward recess at the lower outer end of the main body placement frame 1, ensuring easier manufacturing, lower production costs, and better structural stability and precision. The main body placement frame 1 has a mounting plate 4 facing forward and backward on both the front and rear sides of its upper end. During use, it is placed directly from top to bottom and joined with the existing mounting plate in the width direction for overall connection. The mounting plate 4 has an arc-shaped projection in the forward and backward direction, resulting in more reliable stability during placement and a reliable anti-loosening effect. Especially after placement, it ensures greater stability under the weight of the valve steel bar product. If a flat plate is used for placement, it is prone to displacement, and the positional accuracy cannot be guaranteed. The main body placement frame 1 has symmetrical, inclined safety ramps 3 on its left and right sides, providing more space on both sides. Inside the main body placement area, a first placement groove 5 and a second placement groove 6 are formed on the left and right sides of the placement limiting boss 2. During use, one of these positions is selected for placement of the valve steel bar product. When in use, it can be combined with the support plate in the width direction of the frame. When in use, the valve steel bar can be placed directly on this convenient rack. When placing it, there is a certain space on one side of the placement position, which improves the surrounding air circulation and the annealing efficiency during annealing. When taking it out, the space on the side can be used to easily pick it up with clamping tools, making it more convenient to use. Its width is greater at the top than at the bottom, which makes the space occupied on both sides in the width direction smaller and more convenient to place.

[0012] Preferably, the width of the mounting plate 4 in the left-right direction is the same as the width of the upper left-right direction of the main body mounting frame 1, which makes the overall structural support strength better, the service life during use longer, and the mounting load strength during placement higher, thus ensuring more reliable load-bearing safety when the valve steel bar is placed and used.

[0013] Preferably, the upward protrusion of the placement limiting boss 2 is tilted towards the front or the rear, so that the space occupied on one side is relatively small during placement, while the bar product placed in conjunction can have a stronger load-bearing capacity.

[0014] Preferably, the lower end of the main body placement and fitting frame 1 is located below the placement and limiting fitting boss 2 to form a reinforced support fitting spare groove. As needed, reinforced support components can be combined and used in this position, so that the whole can support the use of heavier bar products during use.

[0015] Preferably, the width of the lower end of the main body placement bracket 1 in the left-right direction is greater than half the width of the upper end of the main body placement bracket 1 in the left-right direction. This ensures better stability of the overall structure and a longer service life. If the lower end width is too small, it is prone to deformation during use, resulting in poor load-bearing capacity.

[0016] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
