Description

Technical Field

[0001] The invention relates to the technical field of heat treatment processing, in particular to a heat treatment tool. Background Art

[0002] Heat treatment refers to a metal heat processing technology in which the material is heated, kept warm and cooled in the solid state to obtain the expected organization and performance. Heat treatment is a metal heat processing technology that heats, keeps warm and cools the metal material in a certain medium to control its performance by changing the metallographic structure on the surface or inside of the material. Heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather changes the microstructure inside the workpiece or the chemical composition on the surface of the workpiece to give or improve the performance of the workpiece. Its characteristic is to improve the intrinsic quality of the workpiece.

[0003] The heat treatment process mainly includes a series of processes such as normalizing, annealing, quenching and tempering. In the quenching stage of heat treatment, the workpiece is often suspended by a sling hook and placed in water to achieve the purpose of quenching. However, in the process of moving the workpiece, the sling and the workpiece are in a suspended state, which can easily cause shaking. The friction between the workpiece and the sling will damage the sling, and the flying sparks caused by excessive shaking will hurt the workers.

[0004] Therefore, a heat treatment tool is proposed. Summary of the invention

[0005] The object of the present invention is to provide a heat treatment tool to solve the problem in the background art that a hanger will shake when a workpiece is suspended and then moved during quenching.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A heat treatment tooling comprises a support plate, a hanging plate, an iron chain, a first fixing frame fixedly mounted on the bottom of the support plate, a reciprocating screw rotatably mounted on the inner wall of the first fixing frame, a slider connected to the reciprocating screw by a spiral transmission, a box body fixedly mounted on the bottom end of the slider; a hanging hook movably mounted on the bottom end of the box body; two movable plates symmetrically hinged on the side walls of the box body; and a clamping mechanism arranged on the side walls of the two movable plates.

[0008] Preferably, the clamping mechanism includes a sliding rod slidably mounted on the side wall of the movable plate, a clamping block is fixedly mounted on one end of the sliding rod close to the hook, a first spring is sleeved on the sliding rod, and both ends of the first spring are respectively fixedly connected to the side wall of the movable plate and one side of the clamping block, and a plurality of sanding blocks are fixedly mounted on the other side of the clamping block.

[0009] By setting mechanisms such as sliding rods, clamping blocks, and a first spring, the hanging plate uses an iron chain to pull up the supporting plate and drive it to move during operation, so that the hook hooks the workpiece, and the reciprocating screw rotates through the original motor fixed on the first fixed frame, and then the workpiece is driven to move by the reciprocating screw and the sliding block. When the hook is used to hook the workpiece, the hook moves downward under the action of the gravity of the workpiece, and the hook drives the movable plate to rotate inward at the bottom of the box under the action of the transmission assembly. The clamping block on the movable plate clamps the workpiece to reduce the shaking of the workpiece during movement. When the work is completed, the workpiece is placed on the ground. After the gravity on the hook is removed, the hook moves upward, and the clamping block is reset along with the transmission assembly and no longer clamps the workpiece.

[0010] Preferably, a first fixing block is fixedly installed on the top of the hook, a connecting plate is fixedly installed on the top of the first fixing block, two symmetrically arranged first connecting rods are hinged on the upper end of the connecting plate, and the top ends of the two first connecting rods are hinged on the side walls of the movable plate.

[0011] By setting up the first fixed block, the connecting plate, the first connecting rod and other mechanisms, when the workpiece is hung on the hook, the hook is driven downward by gravity, and the hook drives the connecting plate to move downward, and the two first connecting rods connected to the upper end of the connecting plate flip downward accordingly, and the movable plates hinged at the top ends of the two first connecting rods rotate inward under the drive of the first connecting rods, thereby driving the subsequent clamping mechanism to clamp the workpiece.

[0012] Preferably, a second fixed block is fixedly installed on the bottom of the box body, a second connecting rod is slidably installed on the middle part of the second fixed block, the bottom end of the second connecting rod is fixedly connected to the upper end of the connecting plate, the top end of the second connecting rod is fixedly installed with a first piston, the first piston is movably installed inside the box body, two symmetrically arranged first ventilation pipes are fixedly installed on the bottom of the box body, a second fixed frame is fixedly installed on one side of the movable plate, a first fixing plate is provided inside the second fixing frame, one side of the first fixing plate is fixedly installed on the other end of the sliding rod, an inflatable spring is fixedly connected to the other side of the first fixing plate, an intake pipe is fixedly installed on one side of the second fixing frame, and the first ventilation pipe and the intake pipe are connected by a hose.

[0013] By setting up the second fixed block, the second connecting rod, the first piston and other mechanisms, when the hook moves downward under the gravity of the workpiece, the connecting plate drives the second connecting rod to slide downward under the drive of the hook, and the first piston installed on the top of the second connecting rod moves downward accordingly. The first piston is made of metal, and the annular side surface is sleeved and fixed with a rubber sealing ring to fit the inner wall of the box body. The first piston is tightly against the inner wall of the box body inside the box body. The air in the inner cavity of the box body below the first piston is squeezed into the inflatable spring through the first ventilation pipe and the intake pipe. The inflatable spring expands and stretches accordingly and pushes the first fixed plate to move, so that the sliding rod promotes the clamping block to clamp the workpiece under the push of the first fixed plate.

[0014] Preferably, two symmetrically arranged sealed boxes are fixedly installed on the bottom of the support plate, a first conductive block is fixedly installed on the inner bottom wall of the box, a first telescopic rod is fixedly installed on the bottom of the first piston, a second conductive block is fixedly installed on the telescopic end of the first telescopic rod, a second spring is sleeved on the first telescopic rod, and the two ends of the second spring are respectively fixedly connected to the bottom of the first piston and the side wall of the second conductive block, electric heating wires are fixedly installed on the inner walls of the two sealed boxes, and the first conductive block, the second conductive block and the heating wires are electrically connected to a power supply through wires.

[0015] By setting up a sealing box, a first conductive block, a first telescopic rod and other mechanisms, the first piston moves downward inside the box body driven by the second connecting rod, and the first conductive block at the bottom end of the first piston moves toward the direction close to the second conductive block. When the first conductive block and the second conductive block contact each other, the circuit here is connected, and current passes through the heating wire at this time, so that the heating wire starts to radiate heat, thereby heating the gas inside the sealing box and realizing control of the heating wire.

[0016] Preferably, two symmetrically arranged second ventilation pipes are fixedly installed on the side walls of the sealing box, four symmetrically arranged multi-section cylinders are fixedly installed on the bottom of the hanging plate, and permanent magnets are fixedly installed at the telescopic ends of the four multi-section cylinders. A third spring is sleeved on the multi-section cylinder, and the two ends of the third spring are respectively fixedly connected to the bottom of the hanging plate and the side wall of the permanent magnet, and the second ventilation pipe and the multi-section cylinder are connected by a hose.

[0017] By setting up a second ventilation pipe, a multi-section cylinder, a permanent magnet and other mechanisms, the gas inside the sealed box is decomposed and expanded by the heating of the heating wire, and the decomposed gas enters the multi-section cylinder through the second ventilation pipe. The multi-section cylinder is extended by the drive of the gas and drives the third spring to extend. The permanent magnet approaches the support plate under the drive of the multi-section cylinder. When the permanent magnet adsorbs the support plate, the support plate and the hanging plate are fixed to each other, so that the support plate is stabilized below the hanging plate, so that the iron chain is always in a straight state during the movement of the hanging plate, thereby reducing the shaking of the support plate.

[0018] Preferably, a water inlet pipe is fixedly installed on one side wall of the box body, and an air outlet pipe is fixedly installed on the other side wall of the box body, control valves are provided inside the water inlet pipe and the air outlet pipe, a water groove is provided inside the second connecting rod, and the top of the water groove and the inner cavity of the box body are connected to each other, and a water outlet groove is provided inside the first fixed block.

[0019] By setting up mechanisms such as a water inlet pipe, an air outlet pipe, and a water trough, the first piston moves downward inside the box body under the drive of the second connecting rod, and the first piston forms a negative pressure in the inner cavity of the box body, so that the control valve in the air outlet pipe is closed and drives the control valve in the water inlet pipe to open and suck water into the box body. The water enters the interior of the second connecting rod through the water trough and flows from the water outlet trough to the hook, so that the second connecting rod and the hook are pre-cooled to prevent the second connecting rod and the hook from being damaged due to excessive temperature changes.

[0020] Preferably, the control valve includes a second fixed plate fixedly mounted on the inner walls of the water inlet pipe and the air outlet pipe, a second telescopic rod is fixedly mounted on one side of the second fixed plate, a second piston is fixedly mounted on the telescopic end of the second telescopic rod, a fourth spring is sleeved on the second telescopic rod, and both ends of the fourth spring are respectively fixedly connected to the second fixed plate and the side walls of the second piston.

[0021] By setting up a second fixed plate, a second telescopic rod, a second piston and other mechanisms, the second piston is driven to move under the action of the negative pressure generated in the inner cavity of the box body, and the second piston drives the second telescopic rod and the fourth spring to contract, so that the second piston opens the valve port of the water inlet pipe, and then water is sucked into the box body. The control valve in the air outlet pipe is sealed under the negative pressure state of the box body, and water produces water vapor under the high temperature emitted by the workpiece. The conditions of the control valves inside the water inlet pipe and the air outlet pipe are opposite to those before, so that the water vapor is discharged from the air outlet pipe. When the work is completed, the first piston is easy to rise.

[0022] Preferably, the sliding rod and the clamping block are both made of martensitic heat-resistant steel.

[0023] Martensitic heat-resistant steel has high strength and high heat resistance, so that the slide rod and the clamp block will not be easily damaged by high temperature when clamping the workpiece, which makes the service life of the slide rod and the clamp block longer, reduces the replacement of the slide rod and the clamp block, and saves resources.

[0024] Preferably, ammonia gas is provided inside the sealed box.

[0025] Ammonia is highly active and is easily decomposed when heated, causing a rapid reaction inside the sealed box, thereby allowing the multi-throttle cylinder to quickly extend under the action of the gas.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By setting up mechanisms such as sliding rods, clamping blocks, and the first spring, when working, the hanging plate uses the iron chain to pull up the supporting plate and drive it to move, so that the hook hooks the workpiece, and then drives the workpiece to move through the reciprocating screw and the slider. When the hook is used to hook the workpiece, the hook moves downward under the gravity of the workpiece, and the hook drives the movable plate to rotate inward at the bottom of the box under the action of the transmission assembly. The clamping block on the movable plate clamps the workpiece to reduce the shaking of the workpiece during movement. When the work is completed, the workpiece is placed on the ground.

[0029] 3. By setting up the second fixed block, the second connecting rod, the first piston and other mechanisms, when the hook moves downward under the gravity of the workpiece, the connecting plate drives the second connecting rod to slide downward under the drive of the hook, and the first piston installed on the top of the second connecting rod moves downward accordingly. The first piston is close to the inner wall of the box body inside the box body, and the air in the inner cavity of the box body below the first piston is squeezed into the inflatable spring through the first ventilation pipe and the air intake pipe. The inflatable spring expands and stretches accordingly and pushes the first fixed plate to move, so that the sliding rod promotes the clamping block to clamp the workpiece under the push of the first fixed plate.

When the first conductive block 26 and the second conductive block 27 contact each other, the circuit here is connected, and current passes through the heating wire 30 at this time, so that the heating wire 30 starts to radiate heat, thereby heating the gas inside the sealing box 25, thereby realizing the control of the heating wire 30.

[0052] As an embodiment of the present invention, refer to Figure 1 Two symmetrically arranged second ventilation pipes 31 are fixedly installed on the side walls of the sealing box 25, and four symmetrically arranged multi-section cylinders 32 are fixedly installed on the bottom of the hanging plate 2.

The first piston 19 forms a negative pressure in the inner cavity of the box body 7, so that the control valve in the air outlet pipe 36 is closed and drives the control valve in the water inlet pipe 35 to open and suck water into the box body 7. The water enters the interior of the second connecting rod 18 through the water groove 41 and flows to the hook from the water outlet groove 42, thereby pre-cooling the second connecting rod 18 and the hook 8 to prevent the second connecting rod 18 and the hook 8 from being damaged due to excessive temperature changes.

[0061] Ammonia is highly active and is easily decomposed when heated, so that the interior of the sealed box 25 can react quickly, thereby allowing the multi-throttle cylinder 32 to quickly extend under the action of the gas.

[0062] Working principle: When a workpiece is hung on the hook 8, the hook 8 is driven downward by gravity, and the hook 8 drives the connecting plate 15 to move downward, and the two first connecting rods 16 connected to the upper end of the connecting plate 15 flip downward accordingly, and the movable plate 9 hinged at the top of the two first connecting rods 16 rotates inwardly under the drive of the first connecting rods 16. During operation, the hanging plate 2 uses the iron chain 3 to pull up the supporting plate 1 and drive it to move, so that the hook 8 hooks the workpiece, and then drives the workpiece to move through the reciprocating screw 5 and the slider 6. When the hook 8 is used to hook the workpiece, the hook 8 moves downward under the action of the gravity of the workpiece, and the hook 8 drives the movable plate 9 to rotate inward at the bottom of the box 7 under the action of the transmission assembly, and the clamping block 11 on the movable plate 9 The workpiece is clamped to reduce the shaking of the workpiece during the movement. When the work is finished, the workpiece is placed on the ground. After the gravity on the hook 8 is removed, the hook 8 moves upward. When the hook 8 moves downward under the action of the gravity of the workpiece, the connecting plate 15 drives the second connecting rod 18 to slide downward under the drive of the hook 8, and the first piston 19 installed on the top of the second connecting rod 18 moves downward accordingly. The first piston 19 is tightly attached to the inner wall of the box body 7 inside the box body 7. The air in the inner cavity of the box body 7 below the first piston 19 is squeezed into the gas spring 23 by the first ventilation pipe 20 and the air intake pipe 24. The gas spring 23 expands and stretches accordingly and pushes the first fixed plate 22 to move. The first piston 19 is driven by the second connecting rod 18 in the box body. The first conductive block 26 at the bottom of the first piston 19 moves downward, and the first conductive block 26 at the bottom of the first piston 19 moves toward the direction close to the second conductive block 27. When the first conductive block 26 and the second conductive block 27 contact each other, the circuit here is connected, and current passes through the heating wire 30 at this time, so that the heating wire 30 begins to emit heat. Under the heating of the heating wire 30, the gas inside the sealed box 25 is decomposed and expanded by heat, and the decomposed gas enters the multi-section cylinder 32 through the second ventilation pipe 31. The multi-section cylinder 32 is extended under the drive of the gas, and drives the third spring 34 to extend. The permanent magnet 33 is driven by the multi-section cylinder 32 to approach the support plate 1. When the permanent magnet 33 adsorbs the support plate 1, the support plate 1 and the hanging plate 2 are fixed to each other, so that The support plate 1 is stabilized below the hanging plate 2. The first piston 19 moves downward inside the box body 7 driven by the second connecting rod 18. The first piston 19 forms a negative pressure in the inner cavity of the box body 7, so that the control valve in the air outlet pipe 36 is closed and drives the control valve in the water inlet pipe 35 to open and suck water into the box body 7. The water enters the interior of the second connecting rod 18 through the water trough 41 and flows to the hook from the water outlet trough 42. The negative pressure generated in the inner cavity of the box body 7 drives the second piston 39 to move. The second piston 39 drives the second telescopic rod 38 and the fourth spring 40 to contract, so that the second piston 39 opens the valve port of the water inlet pipe 35, and then water is sucked into the box body 7. The control valve in the air outlet pipe 36 is sealed under the negative pressure state of the box body 7.
