Description

Technical Field

[0001] This invention relates to the field of steel ball heat treatment technology, and more specifically, to steel ball quenching heat treatment equipment for steel ball production. Background Technology

[0002] In the heat treatment of steel balls, precise temperature control is one of the key factors to ensure the quality of heat treatment. However, existing heat treatment electric furnaces often lack the ability to flexibly adjust and precisely control the oxygen supply. Since the oxygen concentration has a direct impact on the heating effect and final performance of steel balls, especially in heat treatment processes with strong oxidizing properties or requiring specific atmospheric conditions, the appropriate adjustment of the oxygen supply is particularly important. However, the adjustment function of traditional electric furnaces in this regard is very limited, and real-time monitoring and adjustment cannot be achieved, resulting in insufficient stability and repeatability of the process. In addition, although a certain atmosphere needs to be maintained inside the electric furnace to ensure the effect of heat treatment, existing equipment often lacks effective limiting measures to control the oxygen flow, which can easily lead to excessive or insufficient oxygen supply. This not only affects the uniformity of the heat treatment process, but may also cause differences in the surface quality of the steel balls, or even unnecessary oxidation or excessive deoxidation. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a steel ball quenching heat treatment equipment for steel ball production, thereby solving the technical problem mentioned in the background art of the lack of effective limiting measures to control oxygen flow. Technical solution

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel ball quenching heat treatment equipment for steel ball production, comprising a quenching heat treatment furnace body, wherein an oxygen supply pipe is connected to the top surface of the quenching heat treatment furnace body, and a control mechanism is provided at the top end of the oxygen supply pipe. The control mechanism includes an installation sleeve, a connecting sleeve, a mating sleeve, a screw, a push block, an abutment plate, a guide plate, a guide groove, an installation rod, an adjusting plate, a positioning mechanism, and a locking mechanism. The installation sleeve rotates at the top end of the oxygen supply pipe, the connecting sleeve rotates at the top end of the installation sleeve, the mating sleeve is fixed to the inner wall of the connecting sleeve, the screw is threadedly connected to the mating sleeve, the push block is fixed to the bottom end of the screw, multiple sets of abutment plates are provided on the bottom surface of the push block, and multiple sets of guide plates are provided. The guide grooves are distributed on the outer wall of the push block, and multiple sets are distributed on the inner wall of the mounting sleeve and slidably connected to multiple sets of guide plates. Multiple sets of mounting rods are fixed inside the mounting sleeve, and the adjusting plate slides on the outer wall of multiple sets of mounting rods. The positioning mechanism includes a partition block, a limit ring, a mounting plate, a limit strip, a positioning block, a contraction spring, and a limit groove. Multiple sets of partition blocks are distributed on the outer wall of the connecting sleeve, and the limit rings are located on the outer side of multiple sets of partition blocks. The mounting plate is fixed on the outer wall of the mounting sleeve, and multiple sets of limit strips are distributed on the bottom surface of the mounting plate. The positioning block slides on multiple sets of limit strips. Multiple sets of contraction springs are provided, and their two ends are respectively connected to multiple sets of positioning blocks. The limit grooves are located on the inner side of multiple sets of positioning blocks and are all slidably connected to the limit rings.

[0005] The present invention is further configured such that the locking mechanism includes a locking sleeve, a support rod, a limiting block, a rotating sleeve, an unlocking hole, and an arc-shaped groove. The locking sleeve slides on the outer wall of the connecting sleeve. Multiple sets of support rods are distributed on the bottom surface of the locking sleeve. Multiple sets of limiting blocks are installed on the support rods. Each set of support rods has two sets of limiting blocks at its bottom end. The rotating sleeve is rotatably installed on the outer wall of the connecting sleeve. Multiple sets of unlocking holes are distributed on the outside of the rotating sleeve. The arc-shaped groove is located on the outside of the multiple sets of unlocking holes.

[0006] The present invention is further configured such that each of the multiple sets of support rods is provided with a tension spring on its outer side, the top of each of the multiple sets of tension springs is fixedly connected to a locking sleeve, the bottom of each of the multiple sets of tension springs is provided with a connecting plate, the bottom surface of each of the multiple sets of connecting plates is provided with an arc-shaped slider, the rotating sleeve is provided with an annular groove, and the multiple sets of arc-shaped sliders slide within the annular groove.

[0007] The invention is further configured such that each of the multiple sets of adjusting plates is connected to a return spring on its outer side, and the top of each of the multiple sets of return springs is fixedly connected to the inner wall of the mounting sleeve. The return spring ensures that the adjusting plate can return to its initial position after operation, providing a stable reverse restoring force and preventing over- or under-adjustment during the adjustment process, thereby ensuring the accuracy and consistency of oxygen flow regulation.

[0008] The invention is further configured such that each of the multiple sets of mounting rods is polygonal and slidably connected to multiple sets of adjusting plates. The polygonal mounting rod design provides a more stable connection, preventing rotation or offset of the mounting rods during adjustment, and ensuring a more precise and less prone-to-disengage sliding connection between the adjusting plates and the mounting rods.

[0009] The invention is further configured such that the distance between the outer walls of the multiple sets of separator blocks and positioning blocks is arc-shaped. This arc-shaped outer wall design reduces friction and wear between components, ensuring smoother engagement between the positioning blocks and separator blocks, and improving the durability and operational fluidity of the entire positioning mechanism.

[0010] The present invention is further configured such that the inner sides of the multiple sets of adjusting plates and the outer sides of the abutment plates are all provided with rounded corners. This reduces wear on other components and also ensures a smoother contact between the adjusting plates and the abutment plates, thereby improving operational comfort and precision.

[0011] The invention is further configured such that the diameter of each of the multiple sets of unlocking holes is larger than that of the limiting block, and the top of the connecting sleeve is provided with an outer tube. The larger diameter of the unlocking holes ensures smooth unlocking operations, avoiding jamming or inability to unlock due to improper size; the outer tube facilitates connection or operation with external devices, improving the overall system's compatibility and flexibility. Beneficial effects

[0012] Compared with the prior art, the present invention provides a steel ball quenching heat treatment equipment for steel ball production, which has the following beneficial effects: 1. The flow control mechanism, through the cooperation of the screw and the push block, can precisely adjust the position of the push block, thereby controlling the sliding of the adjusting plate on the mounting rod. This mechanism, through the cooperation of the guide plate and the guide groove, effectively avoids deviation during the adjustment process and ensures precise control of oxygen flow. Specifically, the push block drives the adjusting plate to move through a threaded connection, thereby precisely adjusting the size of the oxygen flow gap and achieving fine adjustment of the oxygen supply to the electric furnace. At the same time, the movement of the adjusting plate is also guaranteed by the squeezing action of the return spring to ensure the stability of the adjustment and the reverse recovery capability. This flow control mechanism effectively solves the problem of the inflexible adjustment of the oxygen supply of traditional electric furnaces, and improves the stability and controllability of the heat treatment process.

[0013] 2. The positioning mechanism, through the cooperation of the separator block, limit ring, limit strip, and positioning block, provides a precise limit adjustment function. The sliding of the positioning block on the limit strip and the action of the contraction spring ensure the limit accuracy during the adjustment process, avoiding over- or under-adjustment of the components. Through the sliding cooperation of the limit ring and the limit groove, the positioning block can be precisely positioned at the designated position, ensuring that there is no deviation in the control of oxygen flow. In addition, the design of the positioning mechanism also provides safe limit protection, preventing the components from loosening or misaligning during operation, ensuring the stability and repeatability of the atmosphere environment during heat treatment, and further improving the heat treatment quality of the steel balls.

[0014] 3. The locking mechanism, through the combination design of the locking sleeve, support rod, and limiting block, provides a reliable safety locking function for the entire oxygen flow regulation process. After the regulation is completed, the locking mechanism rotates the rotating sleeve, pushes the locking sleeve, and causes the support rod and limiting block to abut against the rotating sleeve, thereby effectively preventing misoperation or accidental movement of components during the regulation process. This locking mechanism, through the elastic action of the tension spring, ensures that the locking sleeve can return to its initial position after the operation is completed, thereby preventing accidental changes in oxygen supply or locking failure. Overall, the locking mechanism ensures the stability and safety of oxygen flow regulation, providing a more reliable operational guarantee for the heat treatment of steel balls.

The inner wall of the mounting sleeve 3 is slidably connected to multiple sets of guide plates 9. Multiple sets of mounting rods 11 are fixed inside the mounting sleeve 3.

The positioning mechanism includes partition blocks 13, limiting rings 14, mounting discs 15, limiting strips 16, positioning blocks 17, contraction springs 18, and limiting grooves 19. Multiple sets of partition blocks 13 are distributed on the outer wall of the connecting sleeve 4. Limiting rings 14 are located on the outer side of multiple sets of partition blocks 13. The mounting disc 15 is fixed on the outer wall of the mounting sleeve 3. Multiple sets of limiting strips 16 are distributed on the bottom surface of the mounting disc 15. Positioning blocks 17 slide on multiple sets of limiting strips 16. Multiple sets of contraction springs 18 are provided and their two ends are respectively connected to multiple sets of positioning blocks 17. Limiting grooves 19 are located inside multiple sets of positioning blocks 17 and are all slidably connected to limiting rings 14.

[0021] The locking mechanism includes a locking sleeve 20, a support rod 21, a limiting block 22, a rotating sleeve 23, an unlocking hole 24, and an arc-shaped groove 25. The locking sleeve 20 slides on the outer wall of the connecting sleeve 4. The support rod 21 is provided with multiple sets distributed on the bottom surface of the locking sleeve 20. The limiting block is provided with multiple sets installed on the support rod 21. Each set of support rod 21 has two sets of limiting blocks 22 at its bottom end. The rotating sleeve 23 is rotatably installed on the outer wall of the connecting sleeve 4. The unlocking hole 24 is provided with multiple sets distributed on the outside of the rotating sleeve 23. The arc-shaped groove 25 is provided on the outside of the multiple unlocking holes 24.

[0022] Multiple sets of support rods 21 are provided with tension springs 26 on their outer sides. The top of the multiple sets of tension springs 26 is fixedly connected to the locking sleeve 20. The bottom of the multiple sets of tension springs 26 is provided with connecting plates 27. The bottom surface of the multiple sets of connecting plates 27 is provided with arc-shaped sliders 28. The rotating sleeve 23 is provided with an annular groove 29. The multiple sets of arc-shaped sliders 28 slide in the annular groove 29.

[0023] Multiple sets of adjustment plates 12 are each connected to a return spring 30 on their outer side, and the top of each set of return springs 30 is fixedly connected to the inner wall of the mounting sleeve 3.

[0024] The reset spring 30 provides a reverse restoring force, enabling the adjusting plate 12 to automatically return to its initial position after adjustment, ensuring stability and accuracy during the adjustment process, thereby guaranteeing precise control of oxygen flow.

[0025] Multiple sets of mounting rods 11 are all polygonal and are slidably connected to multiple sets of adjusting plates 12.

[0026] The sliding connection between the polygonal mounting rod 11 and the adjusting plate 12 prevents rotation or offset, ensures the stability of the mounting rod 11 during adjustment, and reduces inaccurate adjustment caused by loose connection.

[0027] The distance between the outer walls of the multiple sets of separator blocks 13 and the positioning blocks 17 is set to be arc-shaped.

[0028] The arc-shaped outer wall design reduces friction and wear between the separator block 13 and the positioning block 17, improves their fitting accuracy, and ensures a smoother and more durable positioning process.

[0029] The inner side of the multiple adjustment plates 12 and the outer side of the abutment plate 8 are both provided with rounded corners.

[0030] The rounded corner design avoids sharp friction between the adjustment plate 12 and the contact plate 8 when they come into contact, reducing the risk of wear and damage, while making the contact smoother, which helps to improve the accuracy of adjustment and the comfort of operation.

[0031] The diameter of the multiple unlocking holes 24 is larger than that of the limiting block 22, and the top of the connecting sleeve 4 is provided with an outer tube 31.

[0032] The diameter of the unlocking hole 24 is larger than that of the limiting block 22, ensuring that unlocking is unobstructed and avoiding jamming; the external pipe 31 provides a connection interface with external devices, improving the operational flexibility and compatibility of the entire system.

[0033] In this embodiment, the external pipe 31 is connected to an external oxygen supply device. When it is necessary to adjust the oxygen supply of the electric furnace, rotating the rotating sleeve 23 causes the support rod 21 to slide along the arc groove 25. When multiple sets of support rods 21 move to the unlocking hole 24, multiple sets of tension springs 26 contract and pull the locking sleeve 20 to release the contact with multiple sets of positioning blocks 17. At this time, multiple sets of limiting blocks disengage from the outer wall of the rotating sleeve 23 and move within the unlocking hole 24. Multiple sets of contraction springs 18 elastically reset and push the multiple sets of positioning blocks 17 along the arc groove 25. The limiting ring 14 slides outward to release the contact with the multiple sets of separator blocks 13 and release the limiting of the mounting sleeve 3. The rotating sleeve 23 slides in the guide groove 10 through the guide plate 9, driving the push block 7 to rotate. The push block 7 drives the screw 6 to rotate and engages with the mating sleeve 5 through the threaded connection. This causes the screw 6 to drive the push block 7 to push the multiple sets of adjusting plates 12 to slide along the mounting rod 11 through the multiple sets of abutment plates 8 and squeeze the multiple sets of reset springs 30 respectively. The input amount is adjusted by controlling the oxygen flow gap through the multiple sets of adjusting plates 12.

[0034] More specifically, after adjustment, the multiple sets of positioning blocks 17 are held and slid inward along the limiting strip 16 to compress the contraction spring 18, so that the multiple sets of positioning blocks 17 slide along the limiting ring 14 through the limiting groove 19. Then, the locking sleeve 20 is pushed to abut against the outer wall of the multiple sets of positioning blocks 17. When the locking sleeve 20 moves, it stretches the multiple sets of tension springs 26 and drives the support rod 21 to move in the unlocking hole 24. When the limiting block 22 set at the bottom of the support rod 21 is aligned with the arc groove 25, the rotating sleeve 23 is rotated to make the support rod 21 slide in the arc groove 25, and the multiple sets of limiting blocks 22 abut against the outside of the rotating sleeve 23 to limit the locking sleeve 20. The multiple sets of positioning blocks 17 abut against the multiple sets of separating blocks 13 to limit the installation sleeve 3.

[0035] In summary, during use or operation of the overall equipment: the external pipe 31 is connected to the external oxygen supply device. When it is necessary to adjust the oxygen supply of the electric furnace, rotating the rotating sleeve 23 causes the support rod 21 to slide along the arc groove 25. When multiple sets of support rods 21 move to the unlocking hole 24, multiple sets of tension springs 26 contract and pull the locking sleeve 20 to release the contact with multiple sets of positioning blocks 17. At this time, multiple sets of limit blocks disengage from the outer wall of the rotating sleeve 23 and move within the unlocking hole 24. Multiple sets of contraction springs 18 elastically reset and push multiple sets of positioning blocks. 17. Slide it outward along the limiting ring 14 to release the contact with the multiple sets of separator blocks 13 and release the limiting of the mounting sleeve 3. Rotate the rotating sleeve 23 and slide it in the guide groove 10 through the guide plate 9 to drive the push block 7 to rotate. The push block 7 drives the screw 6 to rotate and engage with the mating sleeve 5 through the thread. This causes the screw 6 to drive the push block 7 to push the multiple sets of adjusting plates 12 to slide along the mounting rod 11 through the multiple sets of abutment plates 8 and squeeze the multiple sets of reset springs 30 respectively. The input amount is adjusted by controlling the oxygen flow gap through the multiple sets of adjusting plates 12.

[0036] After adjustment, hold the multiple sets of positioning blocks 17 and slide them inward along the limiting strip 16 to compress the contraction spring 18, so that the multiple sets of positioning blocks 17 slide along the limiting ring 14 through the limiting groove 19. Then push the locking sleeve 20 to abut against the outer wall of the multiple sets of positioning blocks 17. When the locking sleeve 20 moves, it stretches the multiple sets of tension springs 26 and drives the support rod 21 to move in the unlocking hole 24. When the limiting block 22 set at the bottom of the support rod 21 is aligned with the arc groove 25, rotate the rotating sleeve 23 to make the support rod 21 slide in the arc groove 25, and abut against the outside of the rotating sleeve 23 through the multiple sets of limiting blocks 22 to limit the locking sleeve 20. The multiple sets of positioning blocks 17 abut against the multiple sets of separating blocks 13 to limit the installation sleeve 3.
