Description

Technical Field

[0001] The present application relates to the field of wear-resistant steel ball manufacturing, and in particular to an automatic conveying device for grinding ball production. Background Art

[0002] Grinding balls are the abrasive media of ball mills. They are subjected to strong impact and abrasive wear in ball mills and are consumables. In the manufacturing process of grinding balls, rolled and forged grinding balls (referred to as rolled and forged grinding balls) are produced by applying external force to the heated alloy steel billet by rolling or forging, forming the alloy steel billet into a ball shape, and then using the residual heat for heat treatment.

[0003] The heat treatment quenching process of rolled and forged grinding balls is divided into the following steps: First, the raw steel bars are transported and heated by the medium frequency furnace. The temperature of the steel bars must ensure that the material is completely austenitized and the rolling or forging process is completed. The determination of the heating time is mainly based on meeting the production capacity; second, the steel bars are rolled or forged. During the rolling and forging process, the heat of the material will be lost and the temperature will drop partially; third, the transportation and slow cooling is a uniform adjustment stage. During the mechanical transportation of the rolled and forged steel balls, the high temperature of the steel ball core is gradually transferred to the surface of the steel ball to even the temperature inside and outside the grinding ball; and during the transportation process, the steel ball contacts the air and cools slowly. Under the premise of maintaining the stability of austenite, it is quenched in water at a lower temperature to reduce segregation and reduce quenching stress. This stage is the most critical point of the quenching treatment, and the transportation time and the temperature of the water quenching node must be accurately controlled. Practice has proved that if the quenching node temperature deviation is greater than 15°C, it will seriously affect the performance of the grinding balls; Fourth, water-cooled quenching, the grinding balls are cooled in water during mechanical transportation to transform the austenite structure into martensite; in this stage, there must be a sufficient cooling rate to complete the transformation from austenite to martensite to ensure the hardness of the grinding balls. At the same time, the temperature of the quenching water outlet node must be accurately controlled to reduce the generation of quenching stress; Fifth, the secondary cooling section of the coolant, the grinding balls have completed the transformation from austenite to martensite in the previous stage of water quenching, and then enter the specially formulated coolant, which reduces the cooling rate of the grinding balls by 3-4 times compared to that in water. During the relatively long cooling process, the internal temperature of the grinding balls is slowly uniformized, the quenching stress is released, and the residual stress in the grinding balls is significantly reduced; Sixth, the grinding balls are put into the frame for air cooling to room temperature.

[0004] Regarding the above-mentioned related technologies, in the process of conveying the rolled and forged steel balls to the water quenching, it is necessary to strictly control the water quenching node temperature of the formed steel balls, that is, it is necessary to control the cooling rate of the formed steel balls from rolling and forging to water quenching. At present, the cooling rate is mainly controlled by controlling the conveying speed of the formed steel balls (natural cooling). However, this method has many disadvantages. For example, in a hot environment, the cooling speed of the formed steel balls is slow, and the conveying speed of the steel balls needs to be slowed down, which will extend the production cycle; for example, in an extremely cold environment, the cooling speed of the formed steel balls is fast, and the conveying speed of the steel balls needs to be increased. At this time, the quenching device may not be able to meet the quenching requirements. Summary of the invention

The heat exchange facility can transfer heat to the spiral conveying tube and the spiral conveying tube transfers the heat to the inner cavity of the drum, or the heat exchange facility can absorb the heat of the inner cavity of the drum through the spiral conveying tube.

[0007] By adopting the above technical solution, the spiral conveying tube is fixed on the inner wall of the drum and is coaxially arranged with the drum, so that the grinding balls remain stable during the conveying process, ensuring the uniform distribution and smooth conveying of the grinding balls. At the same time, the side wall of the spiral conveying tube is provided with a group of suction holes that penetrate the inside and outside, and the suction assembly is used to suck the inner cavity of the spiral conveying tube, which can effectively remove dust, metal particles and other impurities on the surface of the grinding balls, and reduce the impact of impurities on the surface quality of the grinding balls during the quenching process. In addition, the heat exchange facility can transfer heat to the spiral conveying tube and further conduct it to the inner cavity of the drum, or absorb the heat in the drum through the spiral conveying tube, thereby achieving slow cooling or accelerated cooling of the grinding balls, ensuring that the temperature control of the grinding balls during the entire conveying process is more accurate, and improving production efficiency and product quality.

[0008] Optionally, there are at least two groups of air suction hole groups, and the two groups of air suction hole groups are symmetrically arranged about the vertical center line of the spiral conveying tube. One of the air suction hole groups includes at least two air suction holes, and the central axis of one air suction hole is inclined toward the top of the grinding ball, and the central axis of the other air suction hole is inclined toward the bottom of the grinding ball.

[0015] By adopting the above technical solution, the function of the heat pipe is to control the temperature of the inner cavity of the drum, thereby controlling the temperature of the grinding balls. The design of the insulation pipe is to avoid directly taking away the heat of the heat pipe during air intake. At the same time, the insulation pipe can also block the influence of impurities on the heat pipe during the air intake process, thereby extending the service life of the heat pipe.

[0016] Optionally, the heat pipe includes a liquid inlet section and a liquid outlet section connected at one end, the liquid inlet section and the liquid outlet section are respectively connected to the inner wall of the spiral conveying pipe, and the inlet of the liquid inlet section and the outlet of the liquid outlet section are located at the same end of the spiral conveying pipe.

[0031] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0032] In the related technology, a rolling and forging device and a quenching device are provided. The rolling and forging device is used to roll and forge steel balls, and the quenching device is used to quench the formed steel balls. The rolling and forging device and the quenching device in this application are both prior arts and will not be described in detail here.

[0033] The present application discloses an automatic conveying device for grinding ball production. Figure 1 and Figure 2 , comprising a roller device 1, a spiral conveying pipe 2, an air suction assembly (not shown in the figure) and a heat exchange facility 3. The roller device 1 is arranged between the forging device and the quenching device, and is used to convey the grinding balls 100 from the forging device to the quenching device. The roller device 1 comprises a roller 11, and the roller 11 can rotate with its own axis as the rotation axis; the spiral conveying pipe 2 is fixed to the inner wall of the roller 11, and the central axis of the spiral conveying pipe 2 is coaxial with the central axis of the roller 11. A grinding ball conveying groove 21 is formed between adjacent sections of the spiral conveying pipe 2 on the same side of the roller 11, and a through hole 21 is formed on the side wall of the spiral conveying pipe 2. The suction hole group 22 inside and outside the spiral conveying pipe 2, the spiral conveying pipe 2 is a heat-conducting pipe; the suction component is connected to one end of the spiral conveying pipe 2, and the suction component is used to suck the inner cavity of the spiral conveying pipe 2; the heat exchange facility 3 is arranged in the spiral conveying pipe 2, the heat exchange facility 3 can transfer heat to the spiral conveying pipe 2 and the spiral conveying pipe 2 transfers the heat to the inner cavity of the drum 11, or the heat exchange facility 3 can absorb the heat of the inner cavity of the drum 11 through the spiral conveying pipe 2, thereby achieving slow cooling or accelerated cooling of the grinding balls 100, ensuring that the temperature control of the grinding balls 100 during the entire conveying process is more accurate.

[0034] Optionally, a support 12 is further provided on the outer periphery of the drum 11, and the drum 11 is rotatably connected to the support 12. In this embodiment, the drum device 1 further includes a drum driving assembly, and the drum driving assembly includes a ring gear 13, a gear 14, and a driving motor 15. The ring gear 13 is fixed to the outer periphery of the drum 11, and the gear 14 is fixed to the output end of the driving motor 15, and the gear 14 is meshed with the ring gear 13. In other embodiments, the drum device 1 can be other devices that can drive the drum 11 to rotate.

[0035] Reference Figure 2 and Figure 3 The spiral conveying tube 2 is spirally arranged and fixed on the inner wall of the drum 11. The spiral conveying tube 2 rotates with the drum 11, and the grinding balls 100 fall into the grinding ball conveying groove 21. When the drum 11 rotates, the grinding balls 100 are pushed by the spiral conveying tube 2 and conveyed along the grinding ball conveying groove 21, thereby making the grinding balls 100 enter and exit the drum 11.

[0036] During the process of pushing the grinding balls 100 through the spiral conveying tube 2, the air suction component sucks the air in the inner cavity of the spiral conveying tube 2, and the gas in the inner cavity of the drum 11 is transported out along the spiral conveying tube 2 through the air suction hole group 22. During the air suction process, impurities such as metal particles and dust on the surface of the grinding balls 100 are removed, thereby reducing the impact of impurities on the surface quenching quality of the grinding balls 100. At the same time, by controlling the heat exchange efficiency of the heat exchange facility 3, the cooling speed and temperature of the grinding balls 100 are accurately controlled, thereby reducing the temperature fluctuation of the quenching node caused by the change of the ambient temperature, thereby improving the quality consistency of the grinding balls 100.

[0037] In a preferred embodiment, there are two groups of air suction hole groups 22, and the two groups of air suction hole groups 22 are symmetrically arranged with respect to the vertical center line of the spiral conveying tube 2. One air suction hole group 22 includes at least two air suction holes 221, and the central axis of one air suction hole 221 is inclined toward the top of the grinding ball 100, and the central axis of the other air suction hole 221 is inclined toward the bottom of the grinding ball 100; when the outer wall of the spiral conveying tube 2 abuts against the outer wall of the grinding ball 100, the outer wall of the grinding ball 100 does not abut against the opening of the air suction hole 221. The design of the air suction hole group 22 enables the grinding ball 100 to be subjected to uniform suction during the conveying process, ensuring that the grinding ball 100 stably moves along the grinding ball conveying groove 21 in the spiral conveying tube 2, and reducing the deviation phenomenon caused by unilateral force. At the same time, the design of the air suction holes 221 in different directions can effectively remove impurities on the surface of the grinding ball 100, ensure the uniformity and consistency of the surface treatment of the grinding ball 100, and improve production efficiency and product quality.

[0038] In other embodiments, the suction hole groups 22 may be designed in multiple groups, and the specific number may be designed according to the adsorption requirements. Optionally, the suction holes 221 may be in the form of round holes, or long slot holes.

[0039] Reference Figure 1 In a preferred embodiment, the air suction assembly includes a filter box and a suction pump connected to each other, and the filter box is connected to one end of the spiral conveying pipe 2. Specifically, the spiral conveying pipe 2 is connected to the filter box through a rotary joint 23, so that the air suction assembly can normally evacuate the inner cavity of the spiral conveying pipe 2 when the drum 11 rotates.

[0040] Reference Figure 3In this embodiment, the heat exchange facility 3 includes a heat pipe 31, a heat exchange control system (not shown in the figure) and a temperature sensor 32. The heat pipe 31 is connected to the inner wall of the spiral conveying pipe 2 and extends along the spiral conveying pipe 2. The heat exchange control system is used to control the heat of the heat pipe 31. The temperature sensor 32 is arranged in the drum 11, and the temperature sensor 32 is communicatively connected with the heat exchange control system.

[0041] The heat pipe 31 may be filled with a heat exchange medium, which includes a gas medium and a liquid medium. The gas medium may be cooling air or hot air, and the liquid medium may be water, cooling liquid, hot liquid, etc.

[0042] Preferably, the heat pipe 31 includes a liquid inlet section 311 and a liquid outlet section 312 connected at one end, the liquid inlet section 311 and the liquid outlet section 312 are respectively connected to the inner wall of the spiral conveying tube 2, and the inlet of the liquid inlet section 311 and the outlet of the liquid outlet section 312 are located at the same end of the spiral conveying tube 2. A heat exchange medium is introduced into the inlet of the liquid inlet section 311, flows along the liquid inlet section 311, flows to the end away from the outlet of the liquid inlet section 311, flows into the liquid outlet section 312, flows along the liquid outlet section 312, and flows out from the outlet of the liquid outlet section 312. During the flow of the heat exchange medium, the heat of the heat pipe 31 and the spiral conveying tube 2 is regulated, and then the heat of the inner cavity of the drum 11 is regulated.

[0043] In order to effectively control the temperature of the inner cavity of the drum 11 through the heat pipe 31, the inner wall of the spiral conveying tube 2 is connected with an insulation tube 4, and a heat pipe installation channel 41 is formed between the inner wall of the insulation tube 4 and the inner wall of the spiral conveying tube 2. The heat pipe 31 is located in the heat pipe installation channel 41, and an air suction channel 42 is formed between the outer wall of the insulation tube 4 and the inner wall of the spiral conveying tube 2. The air suction channel 42 is connected to the air suction hole group 22. The insulation tube 4 is designed to avoid directly taking away the heat of the heat pipe 31 during air suction. At the same time, the insulation tube 4 can also block the influence of impurities on the heat pipe 31 during the air suction process, thereby extending the service life of the heat pipe 31. Optionally, the insulation tube 4 and the spiral conveying tube 2 can be bonded.

[0044] In a preferred embodiment, the temperature sensor 32 is installed on the side of the spiral conveying tube 2 away from the inner wall of the drum 11. This design can prevent the grinding balls 100 from hitting the temperature sensor 32 during the conveying process, thereby causing damage to the temperature sensor 32, because the grinding balls 100 only move in the grinding ball conveying groove 21, and this design also helps to more accurately monitor the temperature of the inner cavity of the drum 11. Multiple temperature sensors 32 can also be set axially on the drum 11, and multiple temperature sensors 32 are used to accurately identify the temperature of various locations in the inner cavity of the drum 11, which is conducive to the heat exchange control system to accurately control the heat exchange medium.

[0045] Reference Figure 1 and Figure 2Optionally, the heat exchange control system may use a liquid-cooled heat exchanger, one end of which is connected to the heat pipe 31 via a rotary joint 23. At this time, due to the rotary connection between the spiral conveying pipe 2 and the heat pipe 31, the rotary joint 23 here uses a multi-channel rotary joint, and the connection between the multi-channel rotary joint 23 and the pipeline is a prior art, which will not be described in detail here.

[0046] Optionally, one end of the spiral conveying tube 2 extending out of the drum 11 can be used as the discharge end of the drum 11, and the other end of the drum 11 can be used as the feed end of the drum 11. In this case, an automatic feeding belt can be set at the feed end of the drum 11, and the grinding balls 100 after rolling and forging can enter the drum 11 from the automatic feeding belt; or they can be fed manually. In addition, one end of the spiral conveying tube 2 extending out of the drum 11 can be used as the feed end of the drum 11, and the other end of the drum 11 can be used as the discharge end of the drum 11. The discharge end of the drum 11 can be directly connected to the quenching device, and the grinding balls 100 transported by the drum 11 can directly fall into the quenching device. In this case, the feed end of the drum 11 can be fed manually or by other devices. The premise at this time is that the rotation of the spiral conveying tube 2 does not interfere with other devices.

[0047] The implementation principle of an automatic conveying device for grinding ball production in the embodiment of the present application is as follows: when the inner cavity of the drum 11 is relatively hot, coolant is introduced into the heat pipe 31. After the coolant flows through the heat pipe 31, it takes away the heat of the heat pipe 31 and the spiral conveying pipe 2, and then takes away the heat of the inner cavity of the drum 11, so as to control the temperature of the grinding balls 100 in the drum 11; for example, when the external environment temperature is relatively low, hot liquid or normal temperature liquid is introduced into the heat pipe 31, and the heat in the heat pipe 31 is dissipated into the inner cavity of the drum 11, thereby reducing the rate of decrease of the temperature of the inner cavity of the drum 11, and then slowing down the rate of decrease of the temperature of the grinding balls 100, and accurately controlling the temperature of the grinding balls 100; in this process, although the air intake holes 221 are absorbing the air in the inner cavity of the drum 11, the number and the air intake power of the air intake holes 221 can be controlled to avoid too fast an air intake rate, and at this time, the entire spiral conveying pipe 2 is generating heat, and the air temperature in the inner cavity of the drum 11 can be kept relatively stable, thereby accurately controlling the temperature of the grinding balls 100. In the present application, the grinding balls 100 are located in the drum 11 during the transportation process, which can reduce the heat dissipated by the grinding balls 100 into the working environment and improve the comfort of the working environment.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
