Description

Technical Field

[0001] This invention relates to the field of heat treatment technology, and in particular to a heat treatment apparatus and method for cutting tools. Background Technology

[0002] In the field of mechanical manufacturing, cutting tools (such as drills, milling cutters, and turning tools) typically undergo heat treatment processes to obtain high hardness, wear resistance, and red hardness. Among these processes, quenching is a key step, which involves rapidly immersing the tool heated to its austenitizing temperature into a quenching medium (such as water, oil, or polymer solution) to cool it and obtain a martensitic structure.

[0003] In the prior art, when quenching a cutting tool, a basket is usually used to support the heated tool and slowly immerse it in the quenching liquid; after the predetermined cooling time is completed, the basket is lifted as a whole to remove the tool from the quenching liquid.

[0004] However, the above method relies heavily on manual unloading, making it difficult to meet the needs of automated and continuous production. Summary of the Invention

[0005] The purpose of this invention is to provide a tool heat treatment device and method, which aims to solve the problem of relying on manual unloading after tool quenching.

The tool heat treatment device also includes two unlocking mechanisms; the two unlocking mechanisms are respectively located on the side of the quenching pool near the discharge slide, and are configured to remove the two locking rods from the two buckles respectively, and drive the tilting plate to rotate.

[0007] The tool heat treatment device also includes a feeding conveyor belt and a discharging conveyor belt; The feeding conveyor belt is fixedly installed on one side of the feeding chute; the discharging conveyor belt is fixedly installed on one side of the discharging chute.

[0008] The locking lever includes a slide bar, a spring, and a locking lever; The slide rod is slidably disposed within the tilting plate; the spring is sleeved on the slide rod; the locking rod is fixedly disposed on one side of the slide rod and passes through the buckle.

[0009] The unlocking mechanism includes a mounting block, a rotating rod, a first electric push rod, an unlocking rod, and a second electric push rod. The mounting block is fixedly mounted on the quenching tank; one end of the rotating rod is rotatably connected to the mounting block, and the other end of the rotating rod is fixedly mounted with the first electric push rod; the unlocking rod is fixedly mounted on the output end of the first electric push rod; the second electric push rod is rotatably mounted on one side of the quenching tank, and the output end of the second electric push rod is rotatably connected to the rotating rod.

[0010] The tool heat treatment device also includes a heat exchange tube; The heat exchange tubes are fixedly installed inside the quenching tank.

[0011] The tool heat treatment device also includes a recycling box; The recycling box is fixedly installed on one side of the quenching tank and located below the discharge conveyor belt.

[0012] The heat treatment device for the cutting tool also includes a splash guard; The splash guard is fixedly installed on the top of the feed chute.

[0013] The quenching pool includes a pool body, a blocking component, and two mounting components; The pool body is provided with a sewage outlet; the blocking component is provided on the side of the sewage outlet by two of the mounting components, and is used to block the sewage outlet.

[0014] The mounting component includes a first mounting ear, a second mounting ear, a screw, and a nut; The first mounting ear is fixedly disposed on the pool body; the second mounting ear is fixedly disposed on the plug; the screw passes through the first mounting ear and the second mounting ear in sequence; the nut is disposed on the screw.

[0015] The present invention also provides a method for heat treatment of cutting tools, comprising the following steps: After the cutting tool is removed from the heat treatment furnace, it is fed into the feed chute. The cutting tool enters the quenching tank and begins quenching. The cutting tool gradually falls to the bottom with the help of a transfer mechanism. Then, under the push of a subsequent transfer mechanism, the cutting tool is gradually pushed to the side of the quenching tank near the discharge chute. Driven by the chain, the transfer mechanism changes from pushing to lifting, raising the cutter to the side of the discharge chute and stopping it; The two unlocking mechanisms begin to operate, removing the two locking levers from the two buckles respectively, and pushing the tilting plate to rotate and tilt. The quenched tool slides down from the inclined plate into the discharge chute, completing the unloading process.

[0016] This invention discloses a heat treatment apparatus and method for cutting tools. The quenching tank is filled with quenching fluid. Each rotating shaft is equipped with two sprockets, and the four rotating shafts have a total of eight sprockets. The four sprockets closest to the motor at the front form a group, supporting one chain and forming a loop. The four sprockets furthest from the motor at the rear also form a group, supporting one chain and forming a loop. The motor can be connected to any one of the rotating shafts. Driven by the motor, the eight sprockets rotate synchronously, and the two chains move synchronously, thereby driving multiple transfer mechanisms to move. These multiple transfer mechanisms circulate around the loop. The T-shaped plate is fixedly mounted on the two chains via the fixed shaft; one end of the tilting plate is rotatably connected to the T-shaped plate, and the other end is a movable end, so the tilting plate can rotate and tilt; when the two locking rods are inserted into the two buckles, the tilting plate cannot rotate; the two unlocking mechanisms are used to remove the two locking rods from the two buckles respectively, and drive the tilting plate to rotate, and at the same time drive the tilting plate to rotate and reset. In use, the heated cutting tool falls from the feed chute into the quenching tank and lands on one of the transfer mechanisms. Driven by the chain, the tool gradually falls to the bottom along with the current transfer mechanism. Then, a subsequent transfer mechanism pushes the tool forward until it is close to the discharge chute. At this point, driven by the chain, the transfer mechanism changes its angle from pushing to lifting, gradually raising the tool from the bottom to the side of the discharge chute and stopping. The two unlocking mechanisms then release the two locking levers from their respective positions. The tool is removed from the two retaining rings, and then the tilting plate rotates. Under the action of gravity, the quenched tool slides from the tilting plate onto the discharge chute. Then, the two unlocking mechanisms drive the tilting plate to rotate and reset, and the two locking rods re-insert into the two retaining rings. Driven by the motor, the chain continues to run. The motor stops for a period of time every few revolutions. At this time, one of the transfer mechanisms moves to the side of the discharge chute to unload the tool. The above method solves the problem of manual unloading of the tool after quenching. Attached Figure Description

[0032] Furthermore, the feeding chute 2 is fixedly disposed on one side of the quenching tank 1; the discharging chute 3 is fixedly disposed on the side of the quenching tank 1 away from the feeding chute 2; four rotating shafts 4 are respectively rotatably disposed on the quenching tank 1; two sprockets 5 are fixedly disposed on each rotating shaft 4; a chain 6 is disposed on the four sprockets 5 on the same vertical plane; the motor 7 is fixedly disposed on one side of the quenching tank 1, and its output end is fixedly connected to one of the rotating shafts 4; multiple transfer mechanisms 8 are disposed on two chains 6; The transfer mechanism 8 includes a fixed shaft 801, a T-shaped plate 802, an inclined plate 803, two buckles 804, and two locking rods 805; The fixed shaft 801 is fixedly disposed between the two chains 6; the T-shaped plate 802 is fixedly disposed on one side of the fixed shaft 801; the tilting plate 803 is rotatably disposed on the T-shaped plate 802; the two buckles 804 are respectively fixedly disposed on the T-shaped plate 802; the two locking rods 805 are disposed on the tilting plate 803; the two locking rods 805 are configured to be inserted into the two buckles 804 respectively to lock the tilting plate 803. The tool heat treatment device also includes two unlocking mechanisms 9; the two unlocking mechanisms 9 are respectively located on the side of the quenching pool 1 near the discharge slide 3, and are configured to remove the two locking rods 805 from the two buckles 804 respectively, and drive the tilting plate 803 to rotate.

[0033] In this embodiment, the quenching tank 1 is filled with quenching fluid; each of the rotating shafts 4 is equipped with two sprockets 5, and the four rotating shafts 4 are equipped with a total of eight sprockets 5; the four sprockets 5 closest to the motor 7 at the front form a group, supporting one chain 6, forming a loop; the four sprockets 5 furthest from the motor 7 at the rear form a group, also supporting one chain 6, forming a loop; the motor 7 can be connected to any of the rotating shafts 4, and under the drive of the motor 7, the eight sprockets 5 rotate synchronously, and the two chains 6 move synchronously; thereby driving the multiple transfer mechanisms 8 to move, and the multiple transfer mechanisms 8 circulate around the loop; The T-shaped plate 802 is fixedly mounted on the two chains 6 via the fixed shaft 801; one end of the tilting plate 803 is rotatably connected to the T-shaped plate 802, and the other end is a movable end, so the tilting plate 803 can rotate and tilt; when the two locking rods 805 are inserted into the two buckles 804, the tilting plate 803 cannot rotate; the two unlocking mechanisms 9 are used to remove the two locking rods 805 from the two buckles 804 respectively, and drive the tilting plate 803 to rotate, and at the same time drive the tilting plate 803 to rotate and reset; both the tilting plate 803 and the T-shaped plate 802 have multiple strip-shaped leakage holes; In use, the heated cutting tool falls from the feed chute 2 into the quenching tank 1, landing on one of the transfer mechanisms 8. Driven by the chain 6, the cutting tool gradually falls to the bottom along with the current transfer mechanism 8. Then, the next transfer mechanism 8 continues to push it forward. After the cutting tool is pushed to the side near the discharge chute 3, the transfer mechanism 8 changes its angle under the drive of the chain 6, changing from pushing to lifting, gradually raising the cutting tool from the bottom to the side of the discharge chute 3 and stopping. The two unlocking mechanisms 9 release the two locking rods 805 from the two latches respectively. The tool is removed from ring 804 and then rotates the tilting plate 803. Under the action of gravity, the quenched tool slides from the tilting plate 803 onto the discharge slide 3. Then, the two unlocking mechanisms 9 drive the tilting plate 803 to rotate and reset, and the two locking rods 805 are reinserted into the two buckles 804. Driven by the motor 7, the chain 6 continues to run. The motor 7 will stop for a period of time after rotating several revolutions. At this time, one of the transfer mechanisms 8 moves to the side of the discharge slide 3 to unload the tool. The above method solves the problem of manual unloading after tool quenching.

[0034] Furthermore, the tool heat treatment device also includes a feeding conveyor belt 10 and a discharging conveyor belt 11; The feeding conveyor belt 10 is fixedly installed on one side of the feeding chute 2; the discharging conveyor belt 11 is fixedly installed on one side of the discharging chute 3.

[0035] In this embodiment, the feeding conveyor belt 10 is connected to the previous station and is used to transport the heated cutting tool, and the discharging conveyor belt 11 is connected to the next station and is used to transport the quenched cutting tool.

[0036] Furthermore, the locking lever 805 includes a slide bar 8051, a spring 8052, and a locking lever 8053; The slide rod 8051 is slidably disposed within the tilting plate 803; the spring 8052 is sleeved on the slide rod 8051; the locking rod 8053 is fixedly disposed on one side of the slide rod 8051 and passes through the buckle 804.

[0037] In this embodiment, the spring 8052 provides a spring force to the slide rod 8051, so that the slide rod 8051 drives the locking rod 8053 to always be inserted into the buckle 804, thereby locking the tilting plate 803; when unlocking is required, push the slide rod 8051 to compress the spring 8052, thereby moving the locking rod 8053 out of the buckle 804.

[0038] Furthermore, the unlocking mechanism 9 includes a mounting block 901, a rotating rod 902, a first electric push rod 903, an unlocking rod 904, and a second electric push rod 905; The mounting block 901 is fixedly mounted on the quenching tank 1; one end of the rotating rod 902 is rotatably connected to the mounting block 901, and the other end of the rotating rod 902 is fixedly mounted with the first electric push rod 903; the unlocking rod 904 is fixedly mounted on the output end of the first electric push rod 903; the second electric push rod 905 is rotatably mounted on one side of the quenching tank 1, and the output end of the second electric push rod 905 is rotatably connected to the rotating rod 902.

[0039] In this embodiment, the mounting block 901 is used to rotatably mount the rotating rod 902, and the rotation axis of the rotating rod 902 coincides with the rotation axis of the tilting plate 803. During unlocking, the first electric push rod 903 pushes the unlocking rod 904 to insert it from the hole on the side of the tilting plate 803, thereby pushing the slide rod 8051 to unlock. Then, the second electric push rod 905 pushes the rotating rod 902 to rotate, thereby causing the tilting plate 803 to rotate and tilt. After unloading, the second electric push rod 905 drives the rotating rod 902 to reset, thereby causing the tilting plate 803 to reset. Then, the first electric push rod 903 drives the unlocking rod 904 to move out of the hole in the tilting plate 803, releasing the slide rod 8051. Then, the spring 8052 pushes the slide rod 8051, causing the locking rod 8053 to re-insert into the buckle 804, thereby re-locking the tilting plate 803.

[0040] Furthermore, the tool heat treatment device also includes a heat exchange tube 12; The heat exchange tube 12 is fixedly installed inside the quenching tank 1.

[0041] In this embodiment, as the quenching continues, the temperature of the quenching liquid will gradually rise. At this time, cooling water can be introduced into the heat exchange tube 12 to exchange heat with the quenching liquid, thereby lowering the temperature of the quenching liquid and recovering residual heat.

[0042] Furthermore, the tool heat treatment device also includes a recycling box 13; The recycling box 13 is fixedly installed on one side of the quenching pool 1 and located below the discharge conveyor belt 11.

[0043] In this embodiment, the discharge conveyor belt 11 is a perforated conveyor belt. After the quenched tool slides from the discharge slide 3 onto the discharge conveyor belt 11, the adhering quenching liquid flows through the discharge conveyor belt 11 and drips into the recycling box 13, thus avoiding contamination and recovering the quenching liquid.

[0044] Furthermore, the tool heat treatment device also includes a splash guard 14; The splash guard 14 is fixedly installed on the top of the feed chute 2.

[0045] In this embodiment, the heated cutting tool will instantly vaporize and cause violent boiling when it enters the quenching liquid. The splash guard 14 prevents the quenching liquid from splashing, ensuring personnel safety and reducing losses.

[0046] Furthermore, the quenching pool 1 includes a pool body 101, a blocking component 102, and two mounting components 103; The pool body 101 is provided with a drain outlet 1011; the blocking component 102 is provided on the side of the drain outlet 1011 by two mounting components 103, and is used to block the drain outlet 1011.

[0047] In this embodiment, during normal use, the blocking component 102 is used to block the drain outlet 1011. After long-term quenching, a lot of impurities will be deposited in the pool 101. At this time, after most of the quenching liquid is discharged, the blocking component 102 can be opened to discharge the impurities from the drain outlet 1011. In addition, the multiple transfer mechanisms 8 can also cyclically scrape and push the impurities at the bottom of the pool 101 toward the drain outlet 1011.

[0048] Furthermore, the mounting component 103 includes a first mounting ear 1031, a second mounting ear 1032, a screw 1033, and a nut 1034; The first mounting ear 1031 is fixedly disposed on the pool body 101; the second mounting ear 1032 is fixedly disposed on the plug 102; the screw 1033 passes through the first mounting ear 1031 and the second mounting ear 1032 in sequence; and the nut 1034 is disposed on the screw 1033.

[0049] In this embodiment, after the screw 1033 passes through the first mounting ear 1031 and the second mounting ear 1032, the nut 1034 is screwed on, and the plug 102 can be installed in the drain outlet 1011. The nut 1034 can be turned forcefully several times to make the plug 102 press against the drain outlet 1011.

[0050] In this embodiment of the tool heat treatment device, the heated tool falls from the feed chute 2 into the quenching tank 1 and lands on one of the transfer mechanisms 8. Driven by the chain 6, the tool gradually falls to the bottom along with the current transfer mechanism 8. Then, the rear transfer mechanism 8 continues to push the tool forward. After the tool is pushed to the side near the discharge chute 3, the transfer mechanism 8 changes its angle under the drive of the chain 6, changing from pushing to lifting, gradually lifting the tool from the bottom to the side of the discharge chute 3 and stopping. The two unlocking mechanisms 9 lock the two locking rods 805. The tool is removed from each of the two retaining rings 804, and then the tilting plate 803 is rotated. Under the action of gravity, the quenched tool slides from the tilting plate 803 onto the discharge slide 3. Then, the two unlocking mechanisms 9 drive the tilting plate 803 to rotate and reset, and the two locking rods 805 are reinserted into the two retaining rings 804. Driven by the motor 7, the chain 6 continues to run. The motor 7 will stop for a period of time after rotating several revolutions. At this time, one of the transfer mechanisms 8 moves to the side of the discharge slide 3 to unload the tool. The above method solves the problem of manual unloading of the tool after quenching.

[0051] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 11 ,in, Figure 11 This is a flowchart illustrating the second embodiment of the present invention.

[0052] The present invention provides a heat treatment method for cutting tools, comprising the following steps: After S1 removes the cutting tool from the heat treatment furnace, it feeds the material through the feed chute 2. S2 tool enters the quenching tank 1 and begins quenching. The tool gradually falls to the bottom with a transfer mechanism 8. Then, under the push of another transfer mechanism 8, the tool is gradually pushed to the side of the quenching tank 1 near the discharge slide 3. Driven by chain 6, S3 changes from pushing to lifting, raising the cutter to the side of the discharge chute 3 and stopping it; S4 The two unlocking mechanisms 9 start to operate, taking the two locking rods 805 out of the two buckles 804 respectively, and pushing the tilting plate 803 to rotate and tilt. The tool, after being quenched by S5, slides down from the tilting plate 803 into the discharge slide 3, completing the unloading process.

[0053] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
