Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment and a production line thereof, and in particular to a steel ball reheating furnace and a steel ball production line. Background Art

[0002] The production of steel balls generally includes process steps such as forging, quenching and tempering. The steel rod is heated to a specified temperature, then cut and forged through forging equipment, and then quenched, tempered and finely ground.

[0003] In the prior art, after forging by forging equipment, the steel ball is basically formed and is directly transported to the quenching equipment for quenching through the conveying equipment. Since most of the conveying equipment adopts an external conveying screw, the temperature of the steel ball will decrease during the conveying process. When it reaches the quenching equipment, its temperature does not meet the quenching requirements, which affects the overall quality of the steel ball. At the same time, the single conveying method does not process the initially forged steel balls, resulting in a large intensity of fine grinding in the later stage. Summary of the invention

[0004] The present application proposes a steel ball reheating furnace and a steel ball production line. After the steel ball is forged, the reheating furnace can be used to maintain and heat the steel ball so that it can reach the quenching temperature. Secondly, the steel ball can be rounded synchronously during the transmission process, thereby reducing the workload of the later fine grinding and improving the production efficiency of the steel ball.

[0005] To this end, the technical solution adopted in this application is as follows: a steel ball reheating furnace, comprising a heating furnace body, a steel ball loading hopper is provided on the upper part of the heating furnace body, a multi-stage centrifugal rotation mechanism and a rolling mechanism that cooperates with the multi-stage centrifugal rotation mechanism to roll the steel balls are provided inside the heating furnace body, and also includes a telescopic power mechanism that drives the rolling mechanism to move up and down.

[0006] By adopting the above technical scheme: the forged steel balls can enter the heating furnace body through the steel ball hopper for heating, and at the same time, through the cooperation of the multi-stage centrifugal rotation mechanism and the rolling mechanism, the steel balls can be rolled while being heated and transported, which can ensure the quenching problem while reducing the intensity of the later fine grinding of the steel balls, thereby improving the processing efficiency of the steel balls.

[0007] Optionally, a heating assembly is provided on the furnace wall of the heating furnace body, and supporting legs are provided at the lower part of the heating furnace body.

[0008] By adopting the above technical solution: the interior of the heating furnace body can be heated and heated by the heating assembly, and the supporting legs are used to support the entire heating furnace body.

[0009] Optionally, the multi-stage centrifugal rotating mechanism includes a driving assembly arranged at the lower part of the heating furnace body, the driving assembly is connected to a rotating shaft, the rotating shaft is located inside the heating furnace body, and its upper end is rotatably connected to a bearing, the upper end of the bearing is fixed to the middle part of the steel ball upper hopper through a cross, and a plurality of steel ball bearings are provided on the rotating shaft.

[0010] By adopting the above technical solution: the driving component can drive the rotating shaft to rotate, and the steel ball bearing part on the rotating shaft rotates accordingly, which can carry the steel balls, and under the action of centrifugal force, the steel balls are thrown to the rolling mechanism for rolling.

[0011] Optionally, the steel ball bearing component includes a truncated plate arranged on the rotating shaft, and the small opening of the truncated plate is radially connected to the rotating shaft.

[0012] By adopting the above technical solution: when the steel ball falls onto the vertebral plate, it rolls toward the side of the vertebral plate. When it rolls between the side of the vertebral plate and the rolling mechanism, the steel ball is rolled at the rolling mechanism driven by the rotating vertebral plate.

[0013] Optionally, the rolling mechanism includes a plurality of material guiding and rolling components cooperating with the vertebral plate, and the material guiding and rolling components are connected to the telescopic power mechanism via a connecting component.

[0014] By adopting the above technical solution: driven by the telescopic power mechanism, the connecting component can move up and down, thereby driving the material guide and rolling component to move up and down, making it easier to roll the steel balls and discharge them to the next-level material guide and rolling component.

[0015] Optionally, the material guiding and rounding assembly comprises a cover body which is covered on the vertebral plate, the upper part of the cover body is provided with a material blocking part, the lower part of the cover body is provided with a rounding part, the inner side of the cover body is provided with a partition plate, and the rounding part is in an arc shape.

[0016] By adopting the above technical solution: when the steel ball rolls to the side of the vertebral plate, the steel ball plate contacts the rounding part, and the rotating vertebral plate causes the steel ball to roll at the rounding part. Of course, by setting a partition plate, multiple steel balls can be separated, and at the same time, the steel balls can roll relatively in the space formed by the vertebral plate, the rounding part and the partition plate, further improving the rolling effect.

At the same time, due to the rise of the cover body, the material blocking part is driven to rise, temporarily blocking the material guide cover to prevent the steel ball from directly rolling out of the heating furnace body due to excessive rolling speed. When the steel ball is loaded, the telescopic power mechanism drives the cover body to move downward again, and the rounding part contacts the upper surface of the vertebral plate. The steel ball that has just been loaded enters the rounding part again. At this time, the material blocking part also moves downward, and the steel ball after one rounding can enter the next vertebral plate, and so on until it is discharged from the heating furnace body.

[0023] The steel ball production line provided in the present application includes forging equipment and the above-mentioned steel ball reheating furnace. The forging equipment is connected to the steel ball upper hopper of the steel ball reheating furnace through a conveying component, and a quenching pool is also provided downstream of the lower chute.

[0024] By adopting the above technical solution, the quenching temperature of the steel balls can be guaranteed, and the steel balls can be rounded at the same time, thereby reducing the workload of later fine grinding and improving the production efficiency of the steel balls.

[0025] The working principle and beneficial effects of this application are: 1. In the present application, the forged steel balls can enter the heating furnace body through the steel ball loading hopper for heating.

[0026] 2. In the present application, when the steel ball rolls to the side of the vertebral plate, the steel ball plate contacts the rounding part, and the rotating vertebral plate causes the steel ball to roll at the rounding part. Of course, by setting a partition plate, multiple steel balls can be separated, and at the same time, the steel balls can roll relatively in the space formed by the vertebral plate, the rounding part and the partition plate, further improving the rolling effect.

[0027] 3. When a rounding is formed after a certain period of time on the upper part, the cover body can be driven to move upward through the telescopic power mechanism, and the rounding part no longer blocks the steel ball, and the steel ball rolls onto the material guide cover. At the same time, due to the rise of the cover body, the material blocking part is driven to rise, temporarily blocking the material guide cover to prevent the steel ball from directly rolling out of the heating furnace body due to excessive rolling speed. When the steel ball is loaded, the telescopic power mechanism drives the cover body to move downward again, and the rounding part contacts the upper surface of the vertebral plate. The steel ball that has just been loaded enters the rounding part again. At this time, the material blocking part also moves downward, and the steel ball after one rounding can enter the next vertebral plate, and so on until it is discharged from the heating furnace body.

The interior of the heating furnace body 100 is provided with a multi-stage centrifugal rotating mechanism 300 and a rolling mechanism 400 that cooperates with the multi-stage centrifugal rotating mechanism 300 to roll the steel balls, and also includes a telescopic power mechanism 500 that drives the rolling mechanism 400 to move up and down.

[0033] The basic principle of this embodiment is as follows: the forged steel balls can enter the heating furnace body 100 through the steel ball loading hopper 200 for heating. At the same time, through the cooperation of the multi-stage centrifugal rotation mechanism 300 and the rolling mechanism 400, the steel balls can be rolled while being heated and transported, which can ensure the quenching problem while reducing the intensity of the later fine grinding of the steel balls, thereby improving the processing efficiency of the steel balls.

[0034] Reference Figure 1 A heating assembly 110 is provided on the furnace wall of the heating furnace body 100, and a supporting leg 120 is provided at the lower part of the heating furnace body 100. The heating assembly 110 can heat the inside of the heating furnace body 100, and the supporting leg 120 is used to support the entire heating furnace body 100.

[0035] The multi-stage centrifugal rotating mechanism 300 in this embodiment includes a driving component 310 arranged at the lower part of the heating furnace body 100, and the driving component 310 is connected to a rotating shaft 320. The rotating shaft 320 is located inside the heating furnace body 100, and its upper end is rotatably connected to a bearing 330. The upper end of the bearing 330 is fixed to the middle of the steel ball upper hopper 200 through a cross 210. A plurality of steel ball bearings are provided on the rotating shaft 320. The driving component 310 can drive the rotating shaft 320 to rotate, and the steel ball bearings on the rotating shaft 320 rotate accordingly, and can carry the steel balls. Under the action of centrifugal force, the steel balls are thrown to the rolling mechanism 400 for rolling. In this embodiment, the driving component 310 can use a servo motor.

[0036] Reference Figure 2 Specifically, the steel ball bearing member includes a truncated plate 340 disposed on the rotating shaft 320, and the small opening of the truncated plate 340 is radially connected to the rotating shaft 320. When the steel ball falls on the truncated plate 340, it rolls toward the side of the truncated plate 340, and when it rolls between the side of the truncated plate 340 and the rolling mechanism 400, the steel ball is rolled at the rolling mechanism 400 under the drive of the rotating truncated plate 340.

[0037] The rolling mechanism 400 in this embodiment includes a plurality of material guide rolling components that cooperate with the vertebral plate 340. The material guide rolling components are connected to the telescopic power mechanism 500 via a connecting component. Driven by the telescopic power mechanism 500, the connecting component can move up and down, thereby driving the material guide rolling component to move up and down, making it easier to roll the steel balls and discharge them to the next-level material guide rolling component.

When the steel ball rolls to the side of the vertebral plate 340, the steel ball plate contacts the rounding part 430, and the rotating vertebral plate 340 causes the steel ball to be rounded at the rounding part 430. Of course, by setting the partition plate 440, multiple steel balls can be separated, and at the same time, the steel balls can roll relatively in the space formed by the vertebral plate 340, the rounding part 430 and the partition plate 440, thereby further improving the rounding effect.

At the same time, due to the rise of the cover body 410, the material blocking part 420 is driven to rise, temporarily blocking the material guiding cover 600 to prevent the steel ball from directly rolling out of the heating furnace body 100 due to excessive rolling speed. When the steel ball is loaded, the telescopic power mechanism 500 drives the cover body 410 to move down again, and the rounding part 430 contacts the upper surface of the vertebral plate 340. The steel ball that has just been loaded enters the rounding part 430 again. At this time, the material blocking part 420 also moves down, and the steel ball after one rounding can enter the next vertebral plate 340, and so on until it is discharged from the heating furnace body 100. The distance between the cover body 410 and the vertebral plate 340 can be gradually reduced from top to bottom, thereby improving the rounding accuracy.

One end of a connecting rod 470 is provided on the transmission rod 460, and the other end of the connecting rod 470 is connected to the cover body 410. The telescopic power mechanism 500 can be an electric cylinder, a pneumatic cylinder or an oil cylinder, etc., which can drive the cover body 410 to move up and down intermittently.

[0041] A material discharge chute 130 is provided at the bottom of the heating furnace body 100 , and the steel balls that have undergone multi-stage rounding can be discharged from the heating furnace body 100 through the material discharge chute 130 , and then can enter the quenching pool for quenching treatment.
