Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel production, in particular to a cooling bed heat preservation device used for the production of bar threaded steel. Background Art

[0002] Rebar, also known as hot-rolled ribbed steel, is an important construction steel material widely used in civil engineering projects such as houses, bridges, and roads. It is named for its distinctive ribbed texture, which strengthens the bond between the steel and concrete, thereby increasing the overall load-bearing capacity of the structure. Rebar is typically classified by diameter, length, and strength grade. Strength grades include HRB335, HRB400, and HRB500, with the number representing the yield strength of the rebar.

[0003] Currently, the main microalloying processes for hot-rolled high-strength rebar are vanadium microalloying and niobium microalloying. When using the niobium microalloying process to produce national standard rebar, a slow cooling method is required after rolling to reduce the temperature of the rebar to ensure the mechanical properties of the steel bar.

[0004] Small-sized rebar, typically with a diameter between 10mm and 16mm, is also known as rebar. After being rolled and placed on a cooling bed, these rebars, due to their small size, cool naturally too quickly, leading to localized substandard mechanical properties. Furthermore, the finished rebar exhibits a non-yield plateau or low yield strength during mechanical tensile testing. This can lead to fracture or yielding during actual use, impacting the building's load-bearing capacity and durability, and ultimately, construction efficiency and structural integrity. Utility Model Content

[0005] The purpose of the utility model is to provide a cooling bed insulation device for the production of bar threaded steel, which slows down the cooling speed, improves the quality stability and is easy to operate, so as to solve the technical problem that small-sized threaded steel has unqualified local mechanical properties due to excessively rapid cooling, thereby affecting the bearing capacity and durability of the building.

[0006] In order to solve the above technical problems, the solutions adopted by the present invention are as follows:

[0007] A cooling bed insulation device for the production of bar and threaded steel, comprising a supporting foot, a base, a hydraulic cylinder, an insulation mechanism, a conveyor belt, a support rod and a moving device; the supporting foot is provided with several and is evenly distributed at the bottom end of the base; the upper end of the support rod is connected to one end of the conveyor belt, and the lower end is connected to the base; the bottom end of the hydraulic cylinder is rotatably connected to the base, and the output end is rotatably connected to the other end of the conveyor belt; the insulation mechanism is provided with several and is evenly distributed on the surface of the conveyor belt, and an insulation layer is provided inside the insulation mechanism, and the bar and threaded steel are wrapped with the openable insulation mechanism for insulation, thereby slowing down the cooling rate of the threaded steel; the moving device is provided with several and is evenly distributed at the bottom end of the base; the moving device comprises a telescopic device and a roller; the roller is mounted on the bottom end of the base through the telescopic device.

[0008] Furthermore, the insulation mechanism includes a semicircular insulation ring, a torsion spring hinge, and an arc-shaped insulation ring; the semicircular insulation ring is fixedly mounted on the surface of the conveyor belt; two arc-shaped insulation rings are provided, and the two ends of the semicircular insulation ring are connected to the two arc-shaped insulation rings respectively via torsion spring hinges. The arc-shaped insulation ring is hinged to the semicircular insulation ring via the torsion spring hinge, and the semicircular insulation ring is fixedly mounted on the surface of the conveyor belt. The rebar is conveyed to the semicircular insulation ring of the insulation mechanism by the conveyor roller. The circular insulation ring and the arc-shaped insulation ring form a circular ring to insulate the rebar, which is then conveyed by the rotation of the conveyor belt. When the insulation mechanism reaches the top of the conveyor belt and flips downward, the arc-shaped insulation ring is pushed open due to the weight of the billet, and the billet falls down to complete the conveyance.

[0009] Furthermore, the insulation mechanism is equipped with a telescopic spring and a pressure plate. The telescopic spring is Y-shaped, with its bottom end connected to the middle of the semicircular insulation ring and its top end connected to the two arc-shaped insulation rings. The pressure plate is fixedly mounted in the middle of the telescopic spring. The bottom end of the Y-shaped telescopic spring is connected to the middle of the semicircular insulation ring, and its top end is connected to the two arc-shaped insulation rings. When the rebar falls into the semicircular insulation rings, the pressure plate is pressed to contract the telescopic spring, pulling the arc-shaped insulation rings inward to merge with the semicircular insulation rings to form a circle, sealing and insulating the rebar.

[0010] Furthermore, the telescopic device includes a rotary arm, a hinge rod, a threaded sleeve, a screw, and a motor; the motor is fixedly mounted at one end inside the base; one end of the screw is connected to the output end of the motor, and the other end is movably connected to the other end inside the base; the threaded sleeve is sleeved on the screw; one end of the rotary arm is rotatably connected to the base, and the other end is connected to the roller; one end of the hinge rod is hingedly connected to the threaded sleeve, and the other end is hingedly connected to the middle part of the rotary arm. The roller is used to push the device to the working position, and the motor is started to drive the screw to rotate forward, thereby driving the threaded sleeve to move to the right. The movement of the threaded sleeve drives the hinge rod to pull the rotary arm to rotate and retract into the base. After the work is completed, the motor is started to drive the screw to rotate in the opposite direction, thereby driving the threaded sleeve to move to the left. The movement of the threaded sleeve drives the hinge rod to pull the rotary arm to rotate and extend out of the base.

[0011] The working principle of this utility model is as follows:

[0012] When in use, the inclination angle of the conveyor belt is adjusted by the hydraulic cylinder, and then the speed of the conveyor belt is adjusted. Then, the pushing device is moved to the working position by the roller, and the motor is started to drive the screw rod to rotate forward, thereby driving the threaded sleeve to move to the right. The movement of the threaded sleeve drives the hinge rod to pull the swing arm to rotate and retract it into the base. The conveyor belt is rotated for transportation. The threaded steel is transported by the conveyor roller to the semicircular insulation ring of the insulation mechanism. The semicircular insulation ring and the arc-shaped insulation ring form a circular ring to insulate the threaded steel. When the threaded steel falls into the semicircular insulation ring, the pressure plate is pressed to shrink the telescopic spring, pulling the arc-shaped insulation ring inward to merge with the semicircular insulation ring. A circle is formed to seal and insulate the rebar. When the insulation mechanism reaches the top of the conveyor belt and turns downward, the arc-shaped insulation ring is pushed open due to the weight of the billet, and the billet falls down to complete the transportation. The two arc-shaped insulation rings are supported by the "Y"-shaped telescopic spring to prevent the arc-shaped insulation ring from closing due to gravity when the conveyor belt rotates to the bottom of the other end and turns upward, resulting in the rebar being unable to enter the insulation mechanism. After the work is completed, the motor is started to drive the screw to rotate in the opposite direction, thereby driving the threaded sleeve to move to the left. The movement of the threaded sleeve pushes the hinge rod to pull the swing arm to rotate and extend out of the base, pushing the device away from the working position.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model adjusts the position of the roller and insulates the rebar through the insulation mechanism, and then transports the rebar to the cooling bed for storage through a conveyor belt. The insulation mechanism can effectively slow down the cooling speed of the rebar, thereby improving the quality stability and avoiding the occurrence of fracture or yielding of the rebar in actual application due to excessive natural cooling.

[0015] 2. The utility model can control the positions of the semicircular insulation ring and the arc-shaped insulation ring through the "Y"-shaped telescopic spring and the pressure plate, so as to avoid the situation that when the conveyor belt rotates to the bottom end of the other end and turns upward, the arc-shaped insulation ring rotates and closes due to gravity, resulting in the threaded steel being unable to enter the semicircular insulation ring of the insulation mechanism.
