Description

Technical Field

[0001] This invention relates to the field of quenching furnace production, specifically a quenching furnace that facilitates workpiece transport. Background Technology

[0002] A quenching furnace is a furnace used to heat workpieces before quenching. Quenching refers to the process of placing a workpiece in a furnace and heating it to a quenching temperature above the critical point and holding it for a certain period of time, and then quickly taking the workpiece out and immersing it in a quenching liquid.

[0003] Currently, workpieces are typically transported into the quenching furnace using a track and mobile equipment. The quenching pool is located at the bottom of the track. After the workpiece is extracted from the furnace, a two-stage lowering assembly is used to directly sink it into the quenching pool. During this process, workers need to work together to place the storage frame, which is compatible with the box-type quenching furnace, onto the track. Since some workpieces are quite heavy, manual transport is troublesome and requires multiple people to assist in the handling, which is inconvenient and troublesome.

[0004] Therefore, a quenching furnace for convenient workpiece transport and its usage method are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a quenching furnace that facilitates workpiece transport. A first motor drives the connecting frame to rotate, and a second motor drives the moving block to move. An electric push rod extends the electric support block further to the side of the quenching tank, contacting the hook of the placement frame and causing the connecting frame to flip. The placement frame, under gravity, maintains a downward angle and is transported to the side of the furnace body. The electric push rod then sends the placement frame into the furnace body. The connection between the support shaft and the placement frame is relatively simple, making connection and disassembly quicker and facilitating workpiece transport and delivery, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quenching furnace for convenient workpiece transport, comprising a furnace body, a quenching pool fixedly connected to one side of the furnace body, a support plate fixedly connected to the upper end of the quenching pool, a vertical shaft fixedly connected to the upper end of the support plate, diagonal braces fixedly connected to both sides of the vertical shaft, a first motor fixedly connected to the vertical shaft, a rotating shaft fixedly connected to the output end of the first motor, and a connecting frame provided on the outer side of the rotating shaft;

[0007] Two rotating plates are fixedly connected to both sides of the connecting frame. A limit groove is opened on the opposite side of the two rotating plates. A support shaft is provided between the two corresponding rotating plates. A hook is sleeved on the support shaft. The bottom end of the hook is fixedly connected to the storage frame.

[0008] The vertical shaft has a first groove on the side near the connecting frame. The first groove has a circular structure and a circular through hole in each groove. By setting a rotating disk in the first groove, the stability of the rotating shaft when it rotates can be improved.

[0009] In a further embodiment, connecting plates are fixedly connected to all four sides of the upper end of the rotating shaft, and a connecting frame is fixedly connected to the side of the connecting plate away from the rotating shaft. The connecting frame provides effective support for the rotating plate and the storage frame.

[0010] In a further embodiment, rotating disks are fixedly connected to both sides of the rotating shaft. The rotating disks are fixedly connected to the output end of the first motor. A ball is in contact with the rotating disk. The ball is rotatably connected to a circular through hole. By setting the ball in contact with the rotating disk within the circular through hole, friction can be reduced and the rotation effect improved when the first motor drives the rotating disk to rotate.

[0011] In a further embodiment, a second motor is provided between the two rotating disks. The second motor is fixedly connected to the connecting frame. A screw is fixedly connected to the output end of the second motor. The screw is rotatably connected to the limiting groove of the rotating plate. A protrusion is threaded on the screw. The protrusion is integrally formed into a movable block by casting. The movable block can be moved by the second motor.

[0012] In a further embodiment, auxiliary rods are inserted into all four sides of the upper end of the movable block. The end of the auxiliary rod away from the support block is fixedly connected to a limit block, and the other end of the auxiliary rod is fixedly connected to the support block to provide auxiliary support for the electric push rod.

[0013] In a further embodiment, an electric push rod is fixedly connected to the side of the movable block away from the connecting frame, and a support block is fixedly connected to the output end of the electric push rod. A support shaft is rotatably connected between the two support blocks, and the frame can be easily connected and disconnected by engaging with the hook.

[0014] In a further embodiment, a compression ring is sleeved on the support shaft. The compression ring is made of metal and contacts the support block. The compression ring can limit the hook and improve the stability of the storage frame during the rotation of the rotating plate.

[0015] In a further embodiment, a fixing block is fixedly connected to both the upper and lower sides of the extrusion ring. The fixing block is rotatably connected to a rotating rod via a first bearing. The rotating rod is rotatably connected to a support block, which allows for easy adjustment of the distance between the two extrusion rings to accommodate different hook distances.

[0016] In a further embodiment, the extrusion ring contacts the hook, and the surface of the extrusion ring has a rough structure to increase friction and improve stability.

[0017] Preferably, the method of using a quenching furnace that facilitates workpiece transport, as described above, includes the following steps:

[0018] A1. The workpiece is placed in the storage frame manually, and the first motor is rotated to tilt the two rotating plates. At the same time, the second motor drives the screw to rotate. The rotation of the screw can cooperate with the limiting groove to move the protrusion and the moving block, and also drive the support block to move.

[0019] A2. Simultaneously start the electric push rod to drive the support block to move to the appropriate position, then connect the support shaft to the hook, and control the first motor and the second motor to rotate, so that the two rotating plates can rotate, the storage frame can be displaced, and the storage frame can be retracted to the bottom of the rotating plate.

[0020] A3. Under the action of the first motor, the placement frame is moved to the furnace body. At the same time, the screw rotates and the electric push rod extends to put the placement frame into the furnace body, so that the support shaft rotates slightly downward, the electric push rod extends, and the hook disengages from the support shaft, and the workpiece in the placement frame is heated.

[0021] A4. Using the first motor, the support shaft is tilted upward in the horizontal direction, and the electric push rod is extended to make the support shaft rotate downward and connect with the hook. After that, the storage frame is removed. Then, the first motor drives the connecting frame to rotate, which drives the rotating plate to rotate, so that the storage frame falls into the quenching tank for quenching. After multiple quenchings, the storage frame can be placed on one side of the quenching tank. The second motor and the electric push rod are used to push the support block to move. At the same time, the first motor drives the rotating plate to rotate, which can make the support shaft disengage and facilitate the removal of the storage frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are: by placing the storage frame on one side of the pool and connecting it with the support shaft, and the first motor driving the rotating shaft and the connecting frame to rotate, the storage frame is kept in a downward force by gravity, and multi-stage extension can be achieved by the screw and the moving block in conjunction with the electric push rod, so that the workpiece can be transported more conveniently, and the connection and disassembly can be convenient.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] The workpieces inside the storage box have varying weights, and sometimes multiple operators need to work together to lift the storage box to the track, making the transport of workpieces quite troublesome.

[0033] Please see Figure 1-6 This embodiment provides a quenching furnace for convenient workpiece transport, including a furnace body 1. A quenching pool 2 is fixedly connected to one side of the furnace body 1. A support plate 3 is fixedly connected to the upper end of the quenching pool 2. A vertical shaft 4 is fixedly connected to the upper end of the support plate 3. Diagonal braces are fixedly connected to both sides of the vertical shaft 4 to improve stability. A first motor 5 is fixedly connected to the vertical shaft 4. The first motor 5 is a forward and reverse motor. A rotating shaft 6 is fixedly connected to the output end of the first motor 5. A connecting frame 8 is provided on the outside of the rotating shaft 6. The rotating plate 9 is supported by the connecting frame 8. The rotating shaft 6 is driven to rotate by the first motor 5, which can drive the connecting frame 8 to rotate.

[0034] Two rotating plates 9 are fixedly connected to both sides of the connecting frame 8. Limiting grooves are opened on the opposite side of the two rotating plates 9. A support shaft 12 is provided between the two corresponding rotating plates 9. A hook is sleeved on the support shaft 12. The bottom end of the hook is fixedly connected to the storage frame. The support shaft 12 is connected by the hook. When the rotating plate 9 is driven by the first motor 5, the weight of the workpiece in the storage frame can keep the storage frame in a vertical state during the rotation.

[0035] A first groove 21 is provided on the side of the vertical shaft 4 near the connecting frame 8. The first groove 21 has a circular structure and a circular through hole is provided in each groove 21. By providing a circular through hole in the first groove 21 and contacting the rotating disk 23 through the ball 22, support is provided for the rotating shaft 6 and the rotating plate 9, and the friction caused by the pressure on the rotating disk 23 during rotation is reduced.

[0036] By setting up hooks and a storage frame and placing it on one side of the quenching tank 2, the hooks are connected by the support shaft 12, which can limit the position of the storage frame. The storage frame can be transported by the rotation of the rotating plate 9. The friction is reduced by the rolling ball 22 and the rotating disk 23, which greatly facilitates the transport and placement.

[0037] Example 2

[0038] It requires multiple operators to work together to lift the storage box onto the transport track of the quenching furnace, which is quite troublesome.

[0039] Please see Figure 1-6 Further improvements were made based on Example 1.

[0040] The connecting frame 8 is fixedly connected to the connecting plate 7, and the connecting plate 7 is fixedly connected to the four sides of the upper end of the rotating shaft 6. The first motor 5 drives the rotating shaft 6 to rotate, which in turn causes the connecting frame 8 to rotate, and the connecting frame 8 provides support for the rotating plate 9.

[0041] A circular through hole is rotatably connected to a ball 22, which contacts a rotating disk 23. The output end of the first motor 5 is fixedly connected to the rotating disk 23, and the rotating disk 23 is fixedly connected to a rotating shaft 6. The rotating shaft 6 drives the rotating disk 23 to rotate, and the first groove 21 provides a limit for the rotating disk 23. The ball 22 is used to reduce friction, making it easier to rotate the rotating plate 9.

[0042] The movable block 19 is integrally cast with a protrusion, which is threadedly connected to the screw 10. The screw 10 is rotatably connected in the limiting groove of the rotating plate 9. The screw 10 is fixedly connected to the output end of the second motor 11. The connecting frame 8 is fixedly connected to the second motor 11. The second motor 11 is located between the two rotating disks 23. The second motor 11 drives the screw 10 to rotate, which causes the movable block 19 to move in the limiting groove of the rotating plate 9, and allows the storage frame to move on the bottom side of the rotating plate 9.

[0043] The support block 17 is fixedly connected to the auxiliary rod 20, the limiting block is fixedly connected to the auxiliary rod 20, and the auxiliary rod 20 is inserted into the four sides of the upper end of the moving block 19, which can provide auxiliary support for the electric push rod 18 and ensure the stability of the storage frame during rotation.

[0044] The support shaft 12 is rotatably connected to two support blocks 17. The support blocks 17 are fixedly connected to the output end of the electric push rod 18. The electric push rod 18 is fixedly connected to the moving block 19. The electric push rod 18 drives the support blocks 17 to move, which makes it convenient to execute the process of the storage frame extending or retracting on the rotating plate 9.

[0045] The first motor 5 drives the rotating shaft 6 to rotate, causing one side of the rotating plate 9 to tilt. The second motor 11 is then activated, driving the screw 10 to rotate and moving the moving block 19 to one side of the rotating plate 9. The electric push rod 18 unfolds, the support block 17 moves, and the support shaft 12 engages with the hook, causing the rotating plate 9 to rotate again. The rotation of the second motor 11 and the first motor 5 causes the support block 17 and the support shaft 6 to retract. During this process, the electric push rod 18 and the second motor 11 operate. The storage frame remains vertical under gravity and is located on the bottom side of the rotating plate 9 during rotation. The first motor 5 transports the storage frame to the furnace body 1. The screw 10 rotates and the electric push rod 18 can perform a pushing operation. During the entry process, only the support block 17 enters the heating area inside the furnace body 1. After heating, the rotating plate 9 rotates repeatedly and undergoes multiple quenching processes. During the final quenching heating of the workpiece, a storage frame can be placed on another rotating plate 9, which can effectively connect the quenching process, shorten the workpiece placement time, and eliminate the need for manual lifting, thereby improving quenching efficiency.

[0046] The storage frame is connected to the support shaft 12 via a hook, but it is prone to wobbling during the rotation of the rotating plate 9.

[0047] Example 3

[0048] Please see Figure 1-6 Further improvements were made based on Example 1.

[0049] The support block 17 contacts the compression ring 13, which is made of metal. The compression ring 13 is sleeved on the support shaft 12, which can conveniently limit the position of the hook.

[0050] The support block 17 is rotatably connected to the rotating rod 16, and the rotating rod 16 is rotatably connected to the fixing block 14 through the first bearing 15. The fixing block 14 is fixedly connected to the upper and lower sides of the extrusion ring 13, which can adjust the distance between the two extrusion rings 13 and adapt to hooks with different distances.

[0051] The compression ring 13 contacts the hook. The surface of the compression ring 13 has a rough structure, which can increase friction and play an auxiliary limiting role, effectively reducing the lateral sway of the storage frame.

[0052] Based on the spacing between the storage frames, rotating the rotating rod 16 causes the two compression rings 13 to move closer to each other and contact the hook, which can prevent the storage frames from shifting laterally, facilitate the connection of storage frames of different sizes, and improve the stability during rotation and movement.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
