Description
Technical Field
[0001] This utility model relates to the field of workpiece heat treatment technology, and in particular to a T-shaped feed channel for steel ball quenching operation. Background Technology
[0002] Currently, the common method for quenching heated steel balls is to place them in a quenching tank after loading them into a basket. However, since the quenching medium is often a mixture of water and quenching agent, and the steel balls piled up in the basket cause uneven pressure on the basket walls, this often leads to deformation and cracking of the basket, resulting in a short service life and high operating costs. Furthermore, because many steel balls are piled up in the basket, the temperature of the inner balls is higher than that of the outer balls during quenching, and the temperature increases further inwards. This uneven cooling during quenching results in lower and uneven hardness of the steel balls.
[0003] Therefore, ensuring that heated steel balls can cool uniformly during quenching, maintaining high processing efficiency, and reducing operating costs has become one of the urgent technical problems to be solved in this field. Utility Model Content
[0004] The technical problem to be solved by this technical solution is how to provide a carrier suitable for quenching heated steel balls, so as to ensure high processing efficiency while uniformly cooling the steel balls and reducing the cost of quenching operation.
[0005] To solve the above-mentioned technical problems, this technical solution provides a T-shaped feed channel for steel ball quenching operations. This T-shaped feed channel is installed in a quenching tank and includes: an installation frame, a top feed channel, a bottom feed channel, at least one intermediate feed channel, and a transfer mesh belt. The installation frame is located on one side of the quenching tank. The top feed channel is fixedly installed on the top of the installation frame and located above the quenching liquid surface in the quenching tank. The end of the top feed channel near the tank wall is the feed end, and the end away from the tank wall is the discharge end. The height of the feed end is higher than the height of the discharge end. The bottom feed channel is fixedly installed at the bottom of the installation frame and located below the quenching liquid surface. The end of the bottom feed channel near the tank wall is the feed end, and the end away from the tank wall... The material discharge end is at a height higher than the material discharge end. At least one intermediate layer material channel is fixedly installed on the mounting frame between the top layer material channel and the bottom layer material channel and is located below the quenching liquid surface. One end of the intermediate layer material channel is the receiving end and the other end is the dropping end, and the height of the receiving end is higher than the dropping end. The receiving end of the upper intermediate layer material channel is located below the dropping end, and the dropping end of the lower intermediate layer material channel is located above the material discharge end. The transfer mesh belt is set in the lower part of the other side of the quenching tank and is located beside the material discharge end. The heated steel balls pass through the material channel in sequence through the material discharge end, dropping end, receiving end, dropping end, material discharge end, and material discharge end, and are simultaneously quenched in the quenching liquid before entering the transfer mesh belt. Accordingly, numerous heated steel balls are sequentially placed at the feed end of the top-level material channel. Each steel ball rolls forward and falls without interference under the influence of the inclined material channel structure and its own gravity, so as to be uniformly cooled in the quenching liquid. The material channels are combined into a "Xiang" shaped structure, which can extend the quenching and cooling time of the steel balls in the quenching liquid, so that the steel balls are fully cooled. Moreover, when the steel balls fall in the quenching liquid, they are affected by the liquid resistance, which reduces the impact on the material channel and themselves, thereby avoiding deformation and damage to the material channel and the steel balls. This not only ensures the high heat treatment efficiency of the steel balls and the high and uniform quenching quality, but also reduces the damage rate of the quenching carrier, thus significantly reducing the operating cost.
[0006] In another implementation of this technical solution, the number of intermediate layer material channels is three. The mounting frame mainly consists of two columns, one crossbeam, two inclined beams, one vertical beam, and two supporting short beams. The two columns are vertically positioned and spaced apart on one side of the quenching tank, with their upper ends above the quenching liquid surface. The crossbeam is horizontally fixed between the upper parts of the two columns. The two inclined beams are parallel vertically and spaced apart below the crossbeam, with one end of the inclined beam away from the tank wall higher than the other end, making the inclined beam inclined and fixedly connected between the two columns. The vertical beam is vertically fixed between the two inclined beams. The two supporting short beams are vertically fixed on the upper part of the crossbeam and the upper part of the column near the tank wall, respectively, with the height of the supporting short beam near the tank wall higher than the height of the other supporting short beam. The top layer material channel is fixedly mounted on the two supporting short beams, while the intermediate layer material channel is located above. The parts near the receiving end and the parts near the discharge end of the material channel are respectively fixed on the uprights away from the tank wall and the upper inclined beam. The parts near the receiving end and the parts near the discharge end of the intermediate layer material channel are respectively fixed on the upper inclined beam and the upright beam. The parts near the receiving end and the parts near the discharge end of the lower intermediate layer material channel are respectively fixed on the uprights away from the tank wall and the lower inclined beam. The height of the parts near the receiving end of each intermediate layer material channel is higher than the height of the parts near the discharge end. The discharge end of the upper intermediate layer material channel is located above the receiving end of the lower intermediate layer material channel in any two adjacent intermediate layer material channels. The parts near the inlet end and the parts near the outlet end of the bottom material channel are respectively fixed on the lower inclined beam and the uprights away from the tank wall. The height of the parts near the inlet end is higher than the height of the parts near the outlet end.
[0007] As another implementation of this technical solution, the T-shaped material channel also includes: several installation parts, each consisting of insert plates, U-shaped slots and bolts. The insert plates and U-shaped slots have corresponding insertion holes on their side walls, while the columns, inclined beams, upright beams and supporting short beams have threaded holes corresponding to the insertion holes. The U-shaped slots are fixedly connected to the columns, inclined beams, upright beams and supporting short beams by aligning their insertion holes with the threaded holes. The insert plates are fixedly connected to the top layer material channel, bottom layer material channel and middle layer material channel near the feed end, discharge end, receiving end, dropping end, inlet end and outlet end, respectively. By inserting the insert plates into the U-shaped slots and aligning the insertion holes with the threaded holes and screwing in the fastening bolts, the top layer material channel, bottom layer material channel and middle layer material channel are detachably and fixedly installed on the columns, inclined beams, upright beams and supporting short beams. Therefore, it not only facilitates the disassembly and maintenance of the top, bottom, and intermediate material channels, but also ensures the structural strength of the material channels and the installation frame.
[0008] As another implementation of this technical solution, the mounting frame further includes: a guide post, which is vertically fixed to one side of the quenching tank and adjacent to the tank wall. A guide groove is provided on a post adjacent to the tank wall, corresponding to the guide post. The guide post can slide up and down through the guide groove and be fitted onto the guide post, allowing the mounting frame to be detachably mounted inside the quenching tank. This facilitates the disassembly and maintenance of the mounting frame.
[0009] As another implementation of this technical solution, the installation frame further includes two lifting lugs, which are respectively fixed to the upper end of the column away from the tank wall and the part of the crossbeam adjacent to the tank wall. This facilitates the lifting operation of the installation frame using cranes or other equipment.
[0010] In another implementation of this technical solution, the top layer channel, bottom layer channel, and middle layer channel are all composed of a bottom plate and two side plates. The bottom plate is horizontally positioned, and the two side plates are vertically fixed to both sides of the bottom plate. The bottom plate and the two side plates together form a semi-open ball track for the steel ball to roll forward. This not only limits the rolling movement of the steel ball but also ensures sufficient contact between the quenching fluid and the steel ball.
[0011] As another implementation of this technical solution, the longitudinal section of the base plate is a concave arc shape. This makes the structure of the material channel more suitable for the rolling of steel balls, reducing the collision between the steel balls and the channel during rolling.
[0012] As another implementation of this technical solution, the bottom plate of the receiving end of the intermediate layer material channel and the bottom plate of the inlet end of the bottom layer material channel both extend upward perpendicularly to the horizontal direction to form a baffle plate. The side plates of the receiving end and the inlet end extend to both sides of each baffle plate, and the longitudinal section at the connection between the bottom plate of the intermediate layer material channel and the baffle plate is arc-shaped. Therefore, when the intermediate layer material channel and the bottom layer material channel receive steel balls falling from the upper material channel, it can ensure that the steel balls smoothly enter their positions and prevent them from rolling off the outside of the material channel.
[0013] As another implementation of this technical solution, the bottom plate, baffle plate, and side plates of the receiving end, as well as the bottom plate, baffle plate, and side plates of the infeed end, all form a buffer section, and each buffer section is sequentially covered with an impact-resistant steel plate layer and a rubber layer. This enhances the buffering capacity of the receiving and infeed ends, further reducing the impact force with the falling steel balls, thereby extending the service life of the T-shaped material channel and further ensuring the quenching quality of the steel balls.
[0014] As another implementation of this technical solution, an inclined buffer plate is provided inside the ball track at the feeding end, and a wedge-shaped opening is provided at the bottom of the ball track at the discharging and dropping ends. Accordingly, the inclined buffer plate can effectively reduce the impact force of the steel ball on the top material channel when it is fed in, and can also allow the steel ball to enter the ball track smoothly; while the wedge-shaped opening can reduce the horizontal acceleration (inertia) of the steel ball during its fall, so as to prevent the steel ball from falling to the outside of the lower material channel.

[0021] like Figure 1The diagram shows a specific embodiment of the "Xiang"-shaped feed channel applied to steel ball quenching operations according to this utility model. This "Xiang"-shaped feed channel (hereinafter referred to as the "Xiang"-shaped feed channel) is installed in the quenching tank 1 and includes a mounting frame 2, a top feed channel 3, a bottom feed channel 4, at least one intermediate feed channel 5, and a transfer mesh belt 7. The mounting frame 2 is located on one side of the quenching tank 1. The top feed channel 3 is fixedly installed on the top of the mounting frame 2 and located above the quenching liquid surface 8 in the quenching tank 1. The end of the top feed channel 3 near the tank wall is the feed end 31, and the end away from the tank wall is the discharge end 32.

After being heated, the steel balls are sequentially fed through the feed end 31, discharge end 32, receiving end 51, dropping end 52, inlet end 41 and outlet end 42 of the above-mentioned material channel. They are simultaneously quenched in the quenching liquid and then collected in the transfer mesh belt 7. After the transfer mesh belt 7 is loaded with a certain number of steel balls, the steel balls have been cooled by the quenching operation and have a high hardness. The transfer mesh belt 7 can be lifted by the hoisting equipment (not shown in the figure) to send the quenched steel balls to the next operation stage. Then, the hoisting equipment sends the empty transfer mesh belt 7 back to the side of the outlet end 42 in the quenching tank 1.
[0022] Specifically, the number of intermediate layer material channels 5 can be three. The mounting frame 2 mainly consists of two columns 21, one crossbeam 22, two inclined beams 23, one vertical beam 24, and two supporting short beams 25. The two columns 21 are vertically positioned and spaced apart on one side of the quenching tank 1, with the upper ends of the columns 21 above the quenching liquid surface 8. The crossbeam 22 is horizontally fixed between the upper parts of the two columns 21. The two inclined beams 23 are parallel vertically and spaced apart below the crossbeam 22, with one end of the inclined beam 23 away from the tank wall higher than the other end. The inclined beam 23 is fixedly connected to the two columns 21 at an incline, and the upright beam 24 is fixedly connected to the two inclined beams 23 vertically. The two supporting short beams 25 are vertically fixedly installed on the upper part of the crossbeam 22 and the upper part of the column 21 near the trough wall, respectively. The height of the supporting short beam 25 near the trough wall is higher than that of the other supporting short beam 25. The top layer material channel 3 is fixedly installed on the two supporting short beams 25. The middle layer material channel 5 located above is located near the receiving end 51 and near the discharge end. The ends 52 are respectively fixedly mounted on the uprights 21 away from the tank wall and on the upper inclined beam 23. The portions of the intermediate layer material channel 5 near the receiving end 51 and near the dropping end 52 are respectively fixedly mounted on the upper inclined beam 23 and the upright beam 24. Similarly, the portions of the lower intermediate layer material channel 5 near the receiving end 51 and near the dropping end 52 are respectively fixedly mounted on the uprights 21 away from the tank wall and on the lower inclined beam 23. Furthermore, the portions of each intermediate layer material channel 5 near the receiving end 52 are... The height of part 1 is higher than the height of part near the material drop end 52. Moreover, the material drop end 52 of the upper intermediate layer material channel 5 in any two adjacent intermediate layer material channels 5 is located above the material receiving end 51 of the lower intermediate layer material channel 5. The parts of the bottom material channel 4 near the material inlet end 41 and near the material outlet end 42 are respectively fixed on the lower inclined beam 23 and the column 21 away from the trough wall. The height of the part near the material inlet end 41 is higher than the height of the part near the material outlet end 42.
[0023] Furthermore, the aforementioned material channel is detachably mounted on the mounting frame 2 via several mounting parts 26, combined with... Figure 2As shown, each mounting part 26 is composed of a plate 261, a U-shaped slot 262, and bolts 263. The plate 261 and the U-shaped slot 262 have corresponding insertion holes 264 on their side walls. The column 21, inclined beam 23, upright beam 24, and supporting short beam 25 have threaded holes 265 corresponding to the insertion holes 264. Several U-shaped slots 262 align their insertion holes 264 with the threaded holes 265, and their side walls can be fixedly connected to the column 21, inclined beam 23, upright beam 24, and supporting short beam 25 by welding. Several plate 261s are respectively fixedly connected to the top layer material channel 3 and the bottom layer material channel 3. The top layer material channel 3, bottom layer material channel 4, and middle layer material channel 5 are detachably fixed to the column 21, inclined beam 23, upright beam 24, and supporting short beam 25 by inserting the insert plate 261 into the U-shaped slot 262, aligning the insertion hole 264 with the screw hole 265, and screwing in the fastening bolt 263. This not only facilitates the disassembly and maintenance of the top layer material channel 3, bottom layer material channel 4, and middle layer material channel 5, but also ensures the structural strength of the installation of the above material channels and the installation frame 2.
[0024] In this utility model, the mounting frame 2 may further include a guide post 27, which is vertically fixed to one side of the quenching tank 1 and adjacent to the tank wall. The column 21 adjacent to the tank wall has a guide groove (not shown in the figure) corresponding to the guide post 27. The guide post 27 can slide up and down through the guide groove and be sleeved on the guide post 27 so that the mounting frame 2 can be detachably mounted in the quenching tank 1. Alternatively, a vertical guide groove (not shown in the figure) can be provided on the guide post 27, and a vertical guide rail (not shown in the figure) can be provided on the column 21. The mounting frame 2 can be detachably mounted in the quenching tank 1 by inserting the guide rail into the guide groove. The use of the guide groove embedding structure is a prior art means, and this utility model does not limit it. In addition, to facilitate the hoisting operation of the installation frame 2 using equipment such as cranes, the installation frame 2 may also include two lifting lugs 28. The two lifting lugs 28 are respectively fixedly installed at the upper end of the column 21 away from the tank wall and at the part of the crossbeam 22 near the tank wall. The lifting lugs 28 are used to hang the hooks of the crane or other equipment, so that the installation frame 2 can be lifted and dismantled or installed on the guide column 27 from above.
[0025] In this invention, the top layer channel 3, the bottom layer channel 4, and the middle layer channel 5 are all composed of a base plate 61 and two side plates 62. The base plate 61 is horizontally arranged, and the two side plates 62 are vertically fixed to both sides of the base plate 61. The longitudinal section of the base plate 61 can be a concave arc shape. The base plate 61 and the two side plates 62 enclose a semi-open ball track for the steel ball to roll forward. This not only limits the rolling of the steel ball, but also allows the quenching liquid to fully contact the steel ball. The arc-shaped base plate 61 also makes the structure of the channel more suitable for the rolling of the steel ball, thereby reducing the phenomenon of the steel ball colliding with the ball track during the rolling process. In addition, when the intermediate layer material channel 5 and the bottom layer material channel 4 receive the steel balls falling from the upper material channel, in order to prevent the steel balls from accidentally rolling to the outside of the material channel, the bottom plate 61 of the receiving end 51 of the intermediate layer material channel 5 and the bottom plate 61 of the inlet end 41 of the bottom layer material channel 4 both extend upward perpendicular to the horizontal direction to form a baffle plate 63. The side plates 62 of the receiving end 51 and the inlet end 41 extend to the sides of each baffle plate 63 respectively. Furthermore, the longitudinal section of the connection between the bottom plate 61 of the intermediate layer material channel 5 and the bottom layer material channel 4 and the baffle plate 63 is set to be arc-shaped. In order to enhance the buffering capacity of the receiving end 51 and the feeding end 41, further reduce the impact force with the falling steel ball, thereby extending the service life of the T-shaped material channel and further ensuring the quenching quality of the steel ball, the bottom plate 61, the baffle plate 63 and the two side plates 62 of the receiving end 51 and the bottom plate 61, the baffle plate 63 and the two side plates 62 of the feeding end 41 are all arranged to form a buffer part, and an impact-resistant steel plate layer 64 and a rubber layer 65 are sequentially covered in each buffer part.
[0026] In this invention, an inclined buffer plate 311 may be provided inside the ball track of the feeding end 31, and a wedge-shaped opening 66 may be provided at the lower part of the ball track of the discharging end 32 and the dropping end 52. The inclined buffer plate 311 can effectively reduce the impact force of the steel ball on the top material channel 3 when it is fed in, and can also make the steel ball enter the ball track smoothly; while the wedge-shaped opening 66 can reduce the horizontal acceleration (inertia) of the steel ball during its fall, so as to prevent the steel ball from falling to the outside of the lower material channel.
[0027] In summary, when using the T-shaped feed channel of this invention to quench heated steel balls, numerous heated steel balls are placed sequentially at the feed end of the top feed channel. Each steel ball rolls forward and falls independently under the influence of the inclined feed channel structure and its own gravity, achieving uniform cooling in the quenching liquid. The T-shaped structure of the feed channels extends the quenching and cooling time of the steel balls in the quenching liquid, ensuring sufficient cooling. Furthermore, the liquid resistance during the fall of the steel balls reduces the impact on the feed channel and the balls themselves, thus preventing deformation and damage. This not only ensures high heat treatment efficiency and high, uniform quenching quality of the steel balls but also reduces the damage rate of the quenching carrier, significantly lowering operating costs.
[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the patent scope of the present utility model. Other equivalent changes made using the patent concept of the present utility model should all fall within the patent protection scope of the present utility model.
