Description

Technical Field

[0001] This invention relates to the technical field of metal heat treatment quenching equipment, specifically to a metal heat treatment quenching equipment. Background Technology

[0002] Metal heat treatment is a process that involves heating a metal or alloy workpiece to a suitable temperature in a specific medium, holding it at that temperature for a certain time, and then cooling it at different rates in different media. This process controls the workpiece's properties by altering the microstructure of its surface or interior. In industrial heat treatment, induction hardening is commonly used for metal workpieces. Induction heating utilizes the resistance heat generated by eddy currents on the workpiece surface to rapidly heat the surface to the quenching temperature, while the core temperature remains relatively constant. Following water cooling, the workpiece surface is hardened, achieving induction surface hardening. However, existing induction hardening equipment typically only clamps one end of the steel pipe. During quenching, the quenching end is prone to angular displacement and wobbling, resulting in poor pipe stability. This leads to less uniform and effective quenching, and makes it difficult to prevent misalignment and positioning of steel pipes with different diameters, thus limiting its practicality.

[0003] Chinese Patent CN112941284B discloses a metal quenching device for metal heat treatment. The invention includes a quenching machine base with several quenching cooling seats symmetrically arranged along its center line. Each quenching cooling seat contains a metal induction hardening component. The quenching machine base also has a central mounting plate with several metal clamping parts symmetrically arranged along its center line. This invention, by setting up an elastic limiting clamping assembly, can clamp and fix the unclamped end of the steel pipe during heat treatment. The assembly rotates synchronously with the steel pipe during heat treatment, without interfering with the quenching process, maintaining the stability of the steel pipe during quenching, preventing angular displacement, improving the uniformity and effect of quenching, and adapting to steel pipes of different diameters. It also offers good positioning and clamping effect and strong practicality.

[0004] The aforementioned patent has the following shortcomings: 1. When quenching a workpiece, quenching with a single medium can easily lead to a large difference in cooling rates between the inside and outside of the workpiece, causing defects such as deformation and cracking. 2. The heating furnace and quenching tank operate independently, which makes it easy for the heat from the heating furnace to be freely released and diffused, resulting in a low heat recovery and utilization rate. Summary of the Invention

[0005] The purpose of this invention is to provide a metal heat treatment quenching device to solve the problems mentioned in the background art.

[0007] Preferably, the atomizing nozzle is fixedly sleeved on the side of the inner wall of the quenching tank, and there are several atomizing nozzles, which are evenly distributed on the side above the oil layer.

A limit column is fixedly connected to the top of the lifting frame. A moving mechanism is provided on the bottom of the base plate. A sliding ball is movably sleeved on the top of the slide rail. A preheating box is fixedly connected to the other side of the top of the base plate. A heat insulation cover is fixedly sleeved on the outside of the preheating box. A preheating mechanism is provided on the other side of the top of the base plate.

[0009] Preferably, the rotating mechanism includes a first gear, which is fixedly sleeved on the top of the rotating column. A first motor is fixedly installed on the top of the closed cover. A second gear is fixedly sleeved on the output shaft of the first motor, and the second gear meshes with the first gear.

[0010] Preferably, the limiting post is movably sleeved on the top of the lifting frame, and there are two limiting posts, which are symmetrically distributed about the cylinder as the axis of symmetry.

[0011] Preferably, the moving mechanism includes a drive base, which is fixedly connected to the bottom of the sliding base. A second motor is fixedly installed on the bottom of the base plate, and a threaded column is fixedly connected to the output shaft of the second motor. The threaded column is threadedly sleeved inside the drive base.

[0012] Preferably, there are several sliding balls, which are evenly distributed on the top of the slide rail.

[0013] Preferably, the heat insulation cover is made of rock wool and is compatible with the preheating box.

[0014] Preferably, the preheating mechanism includes a gas pump, which is fixedly installed on the other side of the top of the base plate. A gas pipe is fixedly sleeved on the side of the gas pump, and the gas pipe is fixedly sleeved on the outside of the preheating box. One end of the gas pipe is fixedly sleeved on the top of the side of the heating furnace.

[0015] The beneficial effects of this invention are as follows: By setting up atomizing nozzles, when quenching metal workpieces, the water pump is started, allowing the water pump to draw water from inside the quenching tank through the delivery pipe, and then spray it into the water pump through the atomizing nozzles to form an atomized water curtain. At this time, the workpiece is placed into the quenching tank, allowing it to pass through the atomized water curtain, the oil layer and the aqueous solution layer in sequence, thereby achieving stable cooling of the workpiece. This avoids the problem of poor uniformity and stability of the cooling rate when the cooling medium is relatively simple, which can lead to workpiece deformation and cracking, thus improving the quenching quality of the workpiece in heat treatment. By setting up a preheating mechanism, when metal parts need to be heated, the workpiece is placed inside the preheating box and the gas pump is started, so that the gas pump can absorb the high-temperature airflow inside the heating furnace through the gas pipe. At this time, the gas pipe can heat the preheating box, that is, preheat the metal parts inside the preheating box, thereby improving the utilization rate of heat inside the heating furnace, that is, improving the working efficiency of the quenching equipment. By setting up a rotating mechanism, when the metal workpiece is being heat-treated, the No. 1 motor is started, which drives the No. 1 gear to rotate through the No. 2 gear. In other words, the metal workpiece is rotated through the rotating column, thereby achieving the effect of rotating and heating the metal workpiece. This improves the uniformity of the metal workpiece during heating, and thus improves the quality of the metal workpiece heat treatment. Attached Figure Description

[0023] Please see Figure 1-6An embodiment of the present invention provides a metal heat treatment quenching device, comprising a base plate 1, a slide rail 2 fixedly connected to the top of the base plate 1, a sliding seat 3 movably sleeved on the top of the slide rail 2, a lifting frame 4 fixedly connected to the top of the sliding seat 3, a heating furnace 5 fixedly connected to the top of the base plate 1, a quenching pool 6 fixedly connected to one side of the top of the base plate 1, an oil layer 7 and an aqueous solution layer 8 disposed inside the quenching pool 6, a water pump 9 fixedly installed on one side of the top of the base plate 1, a conveying pipe 10 fixedly sleeved on the front of the water pump 9, and an atomizing nozzle 11 fixedly installed on the outside of the conveying pipe 10.

[0024] Atomizing nozzles 11 are fixedly sleeved on the side of the inner wall of the quenching tank 6, and there are several atomizing nozzles 11 evenly distributed on the side above the oil layer 7. By setting the atomizing nozzles 11, when the metal workpiece is being quenched, the water pump 9 is started, so that the water pump 9 can draw water from the inside of the quenching tank 6 through the delivery pipe 10, and then spray it into the water pump 9 through the atomizing nozzles 11 to form an atomized water curtain. At this time, the workpiece is put into the quenching tank 6, so that the workpiece passes through the atomized water curtain, the oil layer 7 and the aqueous solution layer 8 in sequence, thereby achieving the stability of the workpiece cooling temperature. This avoids the problem of poor uniformity and stability of the workpiece cooling rate when the cooling medium is relatively simple, which leads to the workpiece deformation and cracking, thereby improving the quenching quality of the workpiece heat treatment.

[0025] A cylinder 12 is fixedly installed on the top of the lifting frame 4. A lifting frame 13 is fixedly connected to the bottom of the cylinder 12. A sealing cover 14 is fixedly connected to the bottom of the lifting frame 13. A rotating column 15 is movably sleeved on the bottom of the sealing cover 14. A clamping arm 16 is movably sleeved on the bottom of the rotating column 15. There are two clamping arms 16, which are symmetrically distributed about the cylinder 12. A rotating mechanism 17 is provided on the top of the sealing cover 14. A limit post 18 is fixedly connected to the top of the lifting frame 13. The bottom of the base plate 1... The unit is equipped with a moving mechanism 19, a sliding ball 20 is movably sleeved on the top of the slide rail 2, a preheating box 21 is fixedly connected to the other side of the top of the base plate 1, a heat insulation cover 22 is fixedly sleeved on the outside of the preheating box 21, and a preheating mechanism 23 is provided on the other side of the top of the base plate 1; by setting up a clamping arm 16, when metal heat treatment is performed, the clamping arm 16 is clamped on the side of the metal part, so that the lifting frame 13 can clamp and lift the workpiece through the clamping arm 16, thereby bringing convenience to the fixing and lifting of the metal part.

[0026] The rotating mechanism 17 includes a first gear 171, which is fixedly sleeved on the top of the rotating column 15. A first motor 172 is fixedly installed on the top of the closed cover 14. A second gear 173 is fixedly sleeved on the output shaft of the first motor 172, and the second gear 173 meshes with the first gear 171. By setting up the rotating mechanism 17, when the metal workpiece is heat-treated, the first motor 172 is started, so that the first motor 172 drives the first gear 171 to rotate through the second gear 173, that is, the metal workpiece is rotated through the rotating column 15, thereby achieving the effect of rotating heating of the metal workpiece, thereby improving the uniformity of the metal workpiece when heated, that is, improving the quality of the metal workpiece heat treatment.

[0027] The limiting post 18 is movably sleeved on the top of the lifting frame 4. There are two limiting posts 18, which are symmetrically distributed about the cylinder 12 as the axis of symmetry. By setting the limiting post 18, when the cylinder 12 drives the metal part to rise and fall through the lifting frame 13, the limiting post 18 can limit the vertical movement of the lifting frame 13, thereby avoiding the problem of tilting and deviation when the lifting frame 13 moves up and down, and thus improving the stability of the workpiece during lifting.

[0028] The moving mechanism 19 includes a drive base 191, which is fixedly connected to the bottom of the sliding seat 3. A second motor 192 is fixedly installed on the bottom of the base plate 1. A threaded column 193 is fixedly connected to the output shaft of the second motor 192, and the threaded column 193 is threadedly sleeved inside the drive base 191. By setting up the moving mechanism 19, when it is necessary to move and transport the workpiece, the second motor 192 is started, so that the second motor 192 can drive the sliding seat 3 to move horizontally through the threaded column 193, that is, drive the lifting frame 4 to move the lifting frame 13 horizontally, thereby achieving the effect of lifting and transporting metal parts.

[0029] There are several sliding balls 20, which are evenly distributed on the top of the slide rail 2. By setting the sliding balls 20, when the lifting frame 4 moves horizontally, the sliding balls 20 can support the horizontally moving sliding seat 3, thereby avoiding the problem of friction between the sliding seat 3 and the top of the slide rail 2 when it moves horizontally, thus improving the smoothness of the horizontal movement of the sliding seat 3, that is, improving the smoothness of the horizontal movement of the workpiece.

[0030] The heat insulation cover 22 is made of rock wool and is compatible with the preheating box 21. By setting the heat insulation cover 22, when the preheating box 21 is heated, the heat insulation cover 22 can block the heat inside the preheating box 21, thereby avoiding the problem of reduced heat utilization caused by rapid heat dissipation inside the preheating box 21, and thus improving the thermal efficiency of the preheating box 21 during operation.

[0031] The preheating mechanism 23 includes a gas pump 231, which is fixedly installed on the other side of the top of the base plate 1. A gas pipe 232 is fixedly sleeved on the side of the gas pump 231 and fixedly sleeved on the outside of the preheating box 21. One end of the gas pipe 232 is fixedly sleeved on the top of the side of the heating furnace 5. By setting up the preheating mechanism 23, when it is necessary to heat the metal parts, the workpiece is placed into the preheating box 21 and the gas pump 231 is started, so that the gas pump 231 can absorb the high-temperature airflow inside the heating furnace 5 through the gas pipe 232. At this time, the gas pipe 232 can heat the preheating box 21, that is, preheat the metal parts inside the preheating box 21, thereby improving the utilization rate of the heat inside the heating furnace 5, that is, improving the working efficiency of the quenching equipment.

[0032] Working principle: During the quenching of metal workpieces, the water pump 9 is started, allowing it to draw water from the quenching tank 6 through the delivery pipe 10. The water is then sprayed through the atomizing nozzle 11 into the water pump 9, forming an atomized water curtain. The workpiece is then placed into the quenching tank 6, passing sequentially through the atomized water curtain, the oil layer 7, and the aqueous solution layer 8. This ensures stable cooling of the workpiece, avoiding the problem of uneven cooling rate and cracking caused by a single cooling medium, thus improving the quality of the heat treatment quenching. During metal heat treatment, the clamping arm 16 clamps the side of the metal workpiece, allowing the lifting frame 13 to pass through... The clamping arm 16 clamps and lifts the workpiece, facilitating the fixing and lifting of the metal part. During the heat treatment of the metal workpiece, the first motor 172 is started, which drives the first gear 171 to rotate via the second gear 173. This, in turn, drives the metal part to rotate via the rotating column 15, achieving a rotating heating effect on the metal part. This improves the uniformity of heating the metal part, thus improving the quality of the heat treatment process. When the cylinder 12 lifts and lowers the metal part via the lifting frame 13, the limiting column 18 limits the vertical movement of the lifting frame 13, preventing tilting or offset during its vertical movement, thereby improving... To ensure stability during workpiece lifting, when workpiece movement and conveying are required, motor 192 is activated. Motor 192 drives the sliding seat 3 horizontally via threaded column 193, which in turn drives the lifting frame 13 horizontally via the lifting frame 4. This achieves the effect of lifting and conveying metal parts. During the horizontal movement of the lifting frame 4, the sliding ball 20 supports the horizontally moving sliding seat 3, preventing friction between the sliding seat 3 and the top of the slide rail 2, thus improving the smoothness of the horizontal movement of the sliding seat 3 and consequently, the smoothness of the horizontal movement of the workpiece. During preheating of the preheating box 21, the heat insulation cover 22 provides insulation for the interior of the preheating box 21. The heat is blocked, which avoids the problem of reduced heat utilization caused by rapid heat dissipation inside the preheating box 21, thereby improving the thermal efficiency of the preheating box 21 during operation. When metal parts need to be heated, the workpiece is placed inside the preheating box 21 and the air pump 231 is started, so that the air pump 231 can absorb the high-temperature airflow inside the heating furnace 5 through the air pipe 232. At this time, the air pipe 232 can heat the preheating box 21, that is, preheat the metal parts inside the preheating box 21, thereby improving the heat utilization rate inside the heating furnace 5, that is, improving the working efficiency of the quenching equipment.
