Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to a bearing steel pipe material heating furnace. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] In order to reduce heat loss, the existing calcining furnace closes the feed port and opens it when material needs to be added. Then the staff adds bearing scrap metal into the calcining furnace, which increases the labor intensity of the staff. Moreover, due to high-temperature calcination, the temperature around the feed port is high when it is opened, which can easily burn the staff. Therefore, further improvements can be made.

A loading plate is fixedly installed on the outer side of the transmission belt, and a transmission assembly is provided on the outer side of the material box.

[0009] Furthermore, the top end of the blanking plate is rotatably connected to a roller rod, and the other side of the transmission belt is sleeved on the outside of the roller rod. The transmission belt is suspended between the blanking plate and the bracket through the roller and the roller rod. The scrap metal inside the material box is transmitted through the transmission belt, and the waste is transferred to the blanking plate in batches through the loading plate.

[0010] Furthermore, the transmission assembly includes a shell fixedly mounted on the outside of the material box, the interior of the shell is rotatably connected to a rotating shaft, a servo motor is fixedly mounted inside the other end of the shell, one end of the rotating shaft and one end of the output shaft of the servo motor are both fixedly mounted with pulleys, and a transmission belt is provided on the outside of the pulley.

[0011] Furthermore, the rotating shaft passes through the side wall of the material box and is fixedly installed at one end of the roller. The side of the pulley close to the inner wall of the shell is rotatably connected to a support rod, and the other end of the support rod is rotatably connected to the side of the inner wall of the shell. The pulley is supported and limited by the support rod, and then the pulley is driven to rotate by the servo motor, which in turn drives the roller to rotate through the rotating shaft, so that the transmission belt transmits the scrap metal.

[0012] Furthermore, the feed opening and closing component includes a feed bottom bin fixedly mounted on the top side of the furnace body, a feed hopper fixedly mounted on the top of the feed bottom bin, the feed hopper is internally rotatably connected to a rotating rod, a horizontal turn plate is fixedly mounted on the outer side of the middle part of the turn rod, the turn rod serves as a rotation fulcrum of the horizontal turn plate and separates the horizontal turn plate from one-fifth, a counterweight is fixedly mounted on one side of the horizontal turn plate, the counterweight is located at one-fifth of the short side of the horizontal turn plate, and the counterweight is used to keep the initial state of the horizontal turn plate horizontal; an optimization component is provided inside the feed bottom bin.

[0013] Furthermore, a positioning column is fixedly installed at the center of the rotating rod, and a spiral spring is sleeved on the outer side of the positioning column, and the other end of the spiral spring is fixed to the outer side of the horizontal rotating plate. The bearing waste is poured into the interior of the feed hopper through the discharge plate, so it will fall onto the long side of the horizontal rotating plate, and then the horizontal rotating plate will be deflected to drive the waste to fall downward, and at the same time, the positioning column will be compressed and curled, and then the counterweight block will assist in driving the horizontal rotating plate to reset and maintain horizontality, so that manual opening and closing is not required, which can reduce heat loss.

When the bearing waste falls downward and hits the inclined rotating plate, the push-pull rod will drive the slider to slide upward, and then compress the compression spring, so it will drive the slider to reset downward later, and then the inclined rotating plate will be driven to rotate through the push-pull rod to block the inside of the feed bottom bin again, further reducing the loss of heat in the furnace.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a bearing steel pipe material heating furnace, which has the following beneficial effects:

[0018] 1. The bearing steel pipe material heating furnace transfers the bearing waste inside the material box to the discharge plate through the loading plate outside the transmission belt. The waste will then fall down along the discharge plate into the discharge plate, causing the horizontal turn plate to deflect and the positioning column to curl. The weight of the counterweight block then assists the horizontal turn plate to reset and maintain horizontality, eliminating the need for manual opening and closing operations, achieving automatic loading and reducing the labor intensity of workers. The inlet can also be closed in time to reduce heat loss in the furnace.

[0019] 2. In the bearing steel pipe material heating furnace, the bearing waste falling into the feed bottom bin will drive the inclined plate to deflect, and then the push-pull rod will drive the slider to slide upward along the inner wall of the limit slot plate, and at the same time compress the compression spring, so the compression spring will then drive the slider to reset downward through its own elastic force, and then the inclined plate will rotate to block the feed bottom bin, thereby further reducing the heat loss in the furnace.

[0037] See also Figure 5-6A positioning column 831 is fixedly installed at the center of the rotating rod 83, and a spiral spring 832 is sleeved on the outer side of the positioning column 831, and the other end of the spiral spring 832 is fixed to the outer side of the horizontal rotating plate 84. The bearing waste is poured into the interior of the feed hopper 82 through the unloading plate 72, so it will fall onto the long side of the horizontal rotating plate 84, and then the horizontal rotating plate 84 will be deflected to drive the waste to fall downward, and at the same time, the positioning column 831 will be compressed and curled, and then the counterweight block 85 will assist in driving the horizontal rotating plate 84 to reset and maintain horizontality, so that manual opening and closing is not required, which can reduce heat loss.

[0038] See also Figure 5 and Figure 7 The optimization component 86 includes a rotating column 861 rotatably connected to both sides of the feed bottom bin 81 and a limiting slot plate 862 fixedly installed inside the feed hopper 82. An inclined rotating plate 863 is fixedly installed between the rotating columns 861 on both sides. The inclined rotating plate 863 is tilted and blocked inside the feed bottom bin 81. One end of the inclined rotating plate 863 is rotatably connected to a push-pull rod 864. The interior of the limiting slot plate 862 is slidably connected to a slider 865. The top end of the push-pull rod 864 is rotatably connected to the middle part of the slider 865. A sliding hole is opened inside the slider 865.

The bearing waste falling downward hits the inclined rotating plate 863, which will cause the push-pull rod 864 to drive the slider 865 to slide upward, and then compress the compression spring 866, so it will subsequently drive the slider 865 to reset downward, and then drive the inclined rotating plate 863 to rotate through the push-pull rod 864 to block the inside of the feed bottom bin 81 again, further reducing the loss of heat in the furnace.

[0039] How it works: See Figure 1-7 First, the scrap metal to be calcined is poured into the material box 71, and then the servo motor 783 is started to drive the rotating shaft 782 to rotate, which in turn drives the rotating roller 75 to rotate, thereby driving the transmission belt 76 to transmit, and then the bearing waste inside the material box 71 is transmitted to the unloading plate 72 through the loading plate 77, and then slides down along the unloading plate 72 into the feed hopper 82, so it will fall on the horizontal rotating plate 84, causing the horizontal rotating plate 84 to deflect and drive the bearing waste thereon to fall downward, while compressing the positioning column 831 to curl up, and then the counterweight block 85 will assist in driving the horizontal rotating plate 84 to reset and keep it horizontal, without the need for manual operation to open and close, thereby closing the inlet in time to reduce heat loss;

[0040] Afterwards, the bearing waste will fall downward into the feed bottom bin 81, so it will fall on the side of the inclined turning plate 863, causing the inclined turning plate 863 to deflect and drive the push-pull rod 864 to push the slider 865 upward, so that the push-pull rod 864 slides upward along the inner wall of the limiting slot plate 862, and at the same time further limits the slider 865 by sliding upward along the limiting rod 867, so the compression spring 866 will be compressed, and the elastic force of the compression spring 866 itself will drive the slider 865 to reset downward, so the inclined turning plate 863 will be driven to rotate through the push-pull rod 864 to block the inside of the feed bottom bin 81 again, further reducing the loss of heat in the furnace.

[0041] To sum up, the bearing steel pipe material heating furnace will transfer the bearing waste inside the material box 71 to the discharge plate 72 through the loading plate 77 on the outside of the transmission belt 76. The waste will then fall down along the discharge plate 72 into the discharge plate 72, thereby driving the horizontal turn plate 84 to deflect and at the same time curling the positioning column 831. The weight of the counterweight block 85 will then assist the horizontal turn plate 84 to reset and maintain the level, thereby eliminating the need for manual opening and closing operations, achieving the effect of automatic loading and reducing the labor intensity of workers. The inlet can also be closed in time to reduce the loss of heat in the furnace.

[0042] The bearing waste falling into the feed bottom bin 81 will cause the inclined plate 863 to deflect, and then the push-pull rod 864 will drive the slider 865 to slide upward along the inner wall of the limiting slot plate 862, and at the same time compress the compression spring 866, so the compression spring 866 will drive the slider 865 to reset downward through its own elastic force, and then the inclined plate 863 will rotate to block the feed bottom bin 81, thereby further reducing the loss of heat in the furnace.
