Description

Technical Field

[0001] This utility model relates to the field of rebar processing technology, specifically to a heat treatment device for rebar. Background Technology

[0002] Rebar is a type of steel reinforcement used in concrete structures. It is named for the threads or ribs on its surface. The main function of rebar is to enhance the tensile and shear strength of concrete, ensuring the stability and safety of the structure. Heat treatment can significantly improve the tensile and yield strength of rebar. At the same time, heat treatment can effectively eliminate the internal stress generated during cold working, reducing the risk of deformation and cracking.

[0003] Publication No. CN221822257U discloses a heat treatment device for rebar, including a quenching tank and a bracket. The bracket consists of a support frame and several layers of partition frames. The support frame is placed in the middle of the quenching tank, and the partition frames are stacked on the support frame. The support frame consists of a base frame and several sets of columns fixed at intervals on both sides of the base frame. Each column has a slot extending upwards on opposite sides, and lifting lugs A are provided at the top of each column. The partition frames include several support plates and fixed crossbeams vertically connected to both sides of the support plates. The support plates are installed at positions corresponding to the slots, with their thickness at both ends matching the slots, and are embedded within the slots. Several slots are spaced apart on the top surface of the support plates. This invention can reduce transfer time, allowing the rebar to cool rapidly and thus increasing its quenching effect. Furthermore, the support frame can orderly separate the rebar, maintaining the consistency of quenching.

[0004] The aforementioned patent addresses the shortcomings of existing technologies where, during the quenching of reinforcing bars, they tend to stack together in the quenching tank, making it difficult for the coolant to cool them synchronously. This results in high cooling efficiency on the outer side and low coolant efficiency on the inner side, leading to inconsistent quenching effects. The patent also improves upon existing technologies by using supports to isolate and support multiple reinforcing bars, allowing for the overall transfer and hoisting of multiple bars. However, the patented technology does not limit and fix the ends of the reinforcing bars when supporting and isolating them, posing a risk of slippage during hoisting and transfer, thus creating a safety hazard during the quenching process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for rebar, which has the advantage of good safety. It solves the problem that in existing technologies, the rebar support and isolation structure does not limit and fix the ends of the rebar during quenching, which poses a risk of the rebar slipping during hoisting and transfer, thus creating a safety hazard during the rebar quenching process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for rebar, comprising a rectangular cylinder, wherein a rebar placement mechanism is provided on the rectangular cylinder;

[0007] The rebar placement mechanism includes multiple horizontal bars, horizontal grid plates, and vertical grid plates fixedly installed inside a rectangular tube. The vertical grid plates penetrate the horizontal bars and horizontal grid plates. A conical cylinder is fixedly installed on the surface of the horizontal bars. The horizontal grid plates and vertical grid plates interpenetrate and intersect to form multiple rectangular cavities. The conical cylinder is located inside the rectangular cavity. A magnetic suction cylinder is fixedly installed on the surface of the rectangular tube. A baffle is rotatably installed on the surface of the rectangular tube. A sleeve is fixedly installed on the surface of the baffle. A U-shaped bolt is slidably installed inside the sleeve.

[0008] Furthermore, two tripods are fixedly installed on the upper surface of the rectangular tube, and a lifting ring is fixedly installed on the top of the tripod.

[0009] Furthermore, both the upper and lower surfaces of the rectangular tube have a mesh structure.

[0010] Furthermore, two reinforcing plates are fixedly installed on both the upper and lower surfaces of the rectangular tube.

[0011] Furthermore, the end of the conical tube with a larger opening diameter faces outward from the rectangular tube, while the end of the conical tube with a smaller opening diameter faces inward from the rectangular tube.

[0012] Furthermore, the U-shaped bolt is compatible with the magnetic suction cylinder.

[0013] Furthermore, a stop block located below the sleeve is fixedly installed at one end of the U-bolt, and the diameter of the stop block is larger than the diameter of the sleeve.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This heat treatment equipment for rebar features a rectangular cavity formed between horizontal and vertical grid plates on the inner side of a rectangular cylinder. A conical cylinder is installed inside the rectangular cavity, and a baffle is provided on one side surface of the rectangular cylinder. During use, the rebar can be fed into the rectangular cavity through the conical cylinder. The baffle and the smaller diameter end of the conical cylinder can limit and stop the rebar at both ends, thus preventing the rebar from slipping out of the rectangular cavity. The entire rectangular cylinder can be placed into a quenching tank for quenching treatment using hoisting equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This embodiment of a heat treatment device for rebar includes a rectangular cylinder 1. Two tripods 11 are fixedly installed on the upper surface of the rectangular cylinder 1. A lifting ring 12 is fixedly installed on the top of the tripods 11. By setting the tripods 11 and lifting rings 12 on the upper surface of the rectangular cylinder 1, it is easy to lift and move the rectangular cylinder 1 to a designated position. A rebar placement mechanism is provided on the rectangular cylinder 1. The rebar placement mechanism includes multiple horizontal bars 2, horizontal grid plates 3 and vertical grid plates 4 fixedly installed on the inner side of the rectangular cylinder 1. The vertical grid plates 4 penetrate the horizontal bars 2 and the horizontal grid plates 3. A conical cylinder 5 is fixedly installed on the surface of the horizontal bars 2. The horizontal grid plates 3 and the vertical grid plates 4 penetrate each other and interweave to form multiple rectangular cavities 6. The conical cylinder 5 is located inside the rectangular cavity 6. A magnetic suction cylinder 7 is fixedly installed on the surface of the rectangular cylinder 1. A baffle 8 is rotatably installed on the surface of the rectangular cylinder 1. A sleeve 9 is fixedly installed on the surface of the baffle 8. A U-shaped bolt 10 is slidably installed inside the sleeve 9.

[0023] The upper and lower surfaces of the rectangular tube 1 are both mesh structures, which facilitates the drainage of water inside the rectangular tube 1. Two reinforcing plates 13 are fixedly installed on the upper and lower surfaces of the rectangular tube 1. By setting the reinforcing plates 13, the strength of the upper and lower surfaces of the rectangular tube 1 can be improved.

[0024] The end of the conical tube 5 with a larger opening diameter faces the outside of the rectangular tube 1, and the end of the conical tube 5 with a smaller opening diameter faces the inside of the rectangular tube 1. This makes it easy to feed the reinforcing bar into the rectangular cavity 6 from the end of the conical tube 5 with a larger opening diameter, while preventing the reinforcing bar from slipping out of the rectangular cavity 6 through the conical tube 5.

[0025] The U-shaped bolt 10 is compatible with the magnetic cylinder 7, making it easy to insert the U-shaped bolt 10 into the magnetic cylinder 7. One end of the U-shaped bolt 10 is fixedly installed with a stop block 14 located below the sleeve 9. The diameter of the stop block 14 is larger than the diameter of the sleeve 9, which helps to prevent the U-shaped bolt 10 from falling off the sleeve 9.

[0026] It should be noted that in this embodiment, the conical cylinder 5 and the baffle 8 are located on both sides of the rectangular cylinder 1.

[0027] The working principle of the above embodiments is as follows:

[0028] In use, close the baffle 8 with one side of the rectangular tube 1, insert the U-shaped bolt 10 into the magnetic suction cylinder 7, and use the magnetic suction cylinder 7 to attract the U-shaped bolt 10. Then, put the steel bar into the rectangular cavity 6 from the end with the larger diameter opening of the conical tube 5. Then, connect the rectangular tube 1 to the tripod 11 and the lifting ring 12 through the hoisting equipment, and immerse the rectangular tube 1 in the quenching tank for quenching. After quenching, pull the U-shaped bolt 10 out of the magnetic suction cylinder 7 to open the baffle 8, and then take out the steel bar from the end of the rectangular tube 1 away from the conical tube 5.
