Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cold rolling roll processing technology, and in particular relates to a cold rolling roll heat treatment device. Background Technology
[0002] This cold rolling mill is a new type of steel bar cold rolling processing equipment. It is the main working component and tool on the mill that causes continuous plastic deformation of the metal. The rolls mainly consist of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in the rolling of the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in a bearing and transmits the rolling force to the stand through the bearing housing and the pressing device. The drive end shaft end is connected to a gear housing via a connecting shaft, transmitting the rotational torque of the motor to the rolls.
[0003] Existing tempering furnaces only have heating and heat preservation functions. However, cold rolls need to be cooled down quickly during tempering. Existing tempering furnaces lack cooling devices. After the cold roll processing is completed, the furnace temperature is too high. When the cold roll is cooled down, the furnace door needs to be opened for natural cooling, which takes a long time and affects production efficiency. Therefore, we propose a heat treatment device for cold rolls. Utility Model Content
[0004] The purpose of this invention is to provide a heat treatment device for cold rolling rolls to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a heat treatment device for cold rolling rolls, comprising: The tempering furnace body has heat dissipation grooves on both sides, and each of the two heat dissipation grooves is equipped with an exhaust fan. The two heat dissipation grooves are connected to the interior of the tempering furnace body. Two side slots are formed on one side of the tempering furnace body, and the two side slots are respectively connected to two heat dissipation slots; Two sealing baffles are respectively movably fitted into two side grooves, and the two sealing baffles are respectively located on one side of two exhaust fans; A movable component is mounted on the tempering furnace body and is used to move two sealing baffles. A sealed furnace cover is provided on the top surface of the tempering furnace body; an inner plate is fixedly installed on the inner side wall of the tempering furnace body, and the inner plate is provided with ventilation holes. Two movable shafts are rotatably mounted on the inner bottom surface of the tempering furnace body, and multiple fan blades are fixedly mounted on the top of each of the two movable shafts. A drive assembly, located within the tempering furnace body, is used to drive two movable shafts to rotate. Multiple heating tubes are fixedly installed on the inner wall of the tempering furnace body. Each heating tube contains a heating wire. After processing, when rapid cooling of the interior of the tempering furnace body is required, motor A is started to drive the rotating shaft to rotate. When the rotating shaft rotates, the inner plate is pushed outward through the cooperation of the second connecting rod, the first connecting rod, and the side seat. When the inner plate moves outward, it drives two sealing baffles to move outward. After the two sealing baffles open, the heat inside the tempering furnace body is discharged to the outside through the heat dissipation slots on both sides. When the heat is discharged, the exhaust fan is started to expel the hot air inside the tempering furnace body, thereby accelerating the cooling of the interior of the tempering furnace body and increasing the cooling speed. During cooling, motor B can also be started to rotate the two movable shafts, and multiple fan blades accelerate the airflow inside the tempering furnace body, further improving the cooling efficiency.
[0006] In the above technical solution, the moving component further includes an inner plate, which is fixedly installed on one side of two sealing baffles. Multiple side seats are fixedly installed on one side of the inner plate. Two mounting plates are fixedly installed on one side of the tempering furnace body. A rotating shaft is rotatably installed between the two mounting plates. Multiple second connecting rods are fixedly installed on the rotating shaft. First connecting rods are rotatably installed within each of the multiple side seats. One side of each of the multiple first connecting rods is rotatably connected to one side of each of the multiple second connecting rods. When the rotating shaft rotates, the inner plate is pushed outwards by the cooperation of the second connecting rods, the first connecting rods, and the side seats. When the inner plate moves outwards, it drives the two sealing baffles to move outwards. After the two sealing baffles open, the heat inside the tempering furnace body is discharged to the outside through the heat dissipation grooves on both sides.
[0007] In the above technical solution, a motor A is further fixedly installed on one side of one of the mounting plates. One end of the output shaft of the motor A is fixedly connected to one end of the rotating shaft. After processing, when it is necessary to quickly cool down the inside of the tempering furnace body, the motor A is started to drive the rotating shaft to rotate.
[0008] In the above technical solution, the drive assembly further includes two sprockets, which are respectively fixedly mounted on two movable shafts. The two sprockets are provided with the same chain. A motor B is fixedly mounted on the bottom surface of the tempering furnace body. The top end of the output shaft of the motor B is fixedly connected to the bottom end of one of the movable shafts. Multiple heating tubes are turned on for heating. When the heating tubes are heating, in order to make the cold rolling rolls heat evenly, the motor B is started to drive one of the movable shafts to rotate. When one of the movable shafts rotates, it will drive the other chain to rotate through the two sprockets and the chain. At this time, the fan blades on the two movable shafts will accelerate the air flow inside the tempering furnace body, so that the heat generated by the heating tubes can be distributed to every corner inside the tempering furnace body.
[0009] In the above technical solution, further, an installation frame is fixedly installed on the outer side wall of the tempering furnace body, and a telescopic cylinder is fixedly installed on the bottom surface of the installation frame. The bottom end of the telescopic cylinder is fixedly connected to the top surface of the sealed furnace cover. When the telescopic cylinder is activated, the sealed furnace cover is lowered or raised to realize the opening and closing of the sealed furnace cover.
[0010] In the above technical solution, furthermore, there are multiple vent holes, and multiple sealed furnace covers are evenly distributed at equal intervals on the inner plate. The air generated by multiple fan blades will pass through multiple vent holes and be delivered to every corner of the tempering furnace body.
[0011] In the above technical solution, the surfaces of both sealing baffles are provided with sealing strips, which will increase the sealing performance and improve the heat preservation effect of the tempering furnace body when the sealing baffles are closed.
[0012] The beneficial effects of this utility model are: 1. In this cold rolling roll heat treatment device, the cold rolling roll to be processed is placed on the inner plate, and the telescopic cylinder is activated to drive the sealing furnace cover to descend, so that the sealing furnace cover is closed with the tempering furnace body. At this time, multiple heating tubes are turned on for heating. While the heating tubes are heating, in order to make the cold rolling roll heat evenly, the motor B is started to drive one of the movable shafts to rotate. When one movable shaft rotates, it drives another chain to rotate through two sprockets and chains. At this time, the fan blades on the two movable shafts will accelerate the air flow in the tempering furnace body, so that the heat generated by the heating tubes is distributed to every corner of the tempering furnace body, thereby making the cold rolling roll heat evenly.
[0013] 2. In this cold rolling mill heat treatment device, when rapid cooling of the tempering furnace body is required after processing, motor A is started to drive the rotating shaft to rotate. When the rotating shaft rotates, the inner plate is pushed outward through the cooperation of the second connecting rod, the first connecting rod, and the side seat. When the inner plate moves outward, it drives the two sealing baffles to move outward. After the two sealing baffles are opened, the heat inside the tempering furnace body will be discharged to the outside through the heat dissipation grooves on both sides. When the heat is discharged, the exhaust fan is started to discharge the hot air inside the tempering furnace body, thereby accelerating the cooling inside the tempering furnace body and increasing the cooling speed. During cooling, motor B can also be started to rotate the two movable shafts, and the air flow inside the tempering furnace body is accelerated through multiple fan blades, further improving the cooling efficiency.
