Technical Field

[0001] The present invention relates to the technical field of heat treatment equipment, and in particular to a method and device for heat treatment of the surface of a mechanical metal part. Background Art

[0002] Heat treatment of metal parts is a metal heat treatment process that obtains corresponding properties by heating, cooling and changing the surface structure of the workpiece. Surface heat treatment of steel parts can obtain a high-hardness martensitic structure on the surface while retaining the toughness and plasticity of the core, improving the comprehensive mechanical properties of the workpiece, making the surface have a higher wear resistance, and greatly improving the overall fatigue resistance of the workpiece. The metal parts heat treatment device is a commonly used processing device in the heat treatment process.

[0015] A processing method for a surface heat treatment device of a mechanical metal part, the processing method further comprises the following steps:

[0016] Step 1: Place the entire device at a predetermined position of use and power it on. When the entire device needs to be used to quench a metal part, first slide the first electric slider inside the first slide slot. The second electric telescopic rod can be used to adjust the vertical position of the second connecting block. Rotate the first electric rotating rod between the second electric telescopic rod and the first connecting block so that the two second clamps at the bottom of the second mounting plate can clamp and fix the metal part to be processed. The fourth electric telescopic rod can be used to adjust the vertical position of the two second clamps so that the second clamps can clamp and fix the metal part to be processed at any position, and move the metal part to the groove at the top of the box for quenching.

[0017] Step 2: Close the first water outlet and each second water outlet, and spray a preset amount of water toward the inside of the groove through the corresponding water outlet plate. When the metal part is placed in the groove, quenching can begin. During the quenching process, each roller can be rotated by the corresponding fourth electric rotating rod, so that the roller can rotate the metal part through rolling friction to improve the quenching efficiency.

[0018] Step three: open the first water outlet, the quenched water will flow into the water tank from the first water outlet to temporarily collect the waste water, and then the waste water can be discharged through the drain at the bottom of the water tank. When the metal parts to be processed are large in size, the metal parts to be processed can be clamped and fixed by the second clamp, and then the metal parts can be placed in the chamber away from the first water outlet, and then the metal parts can be clamped and fixed by the second clamp to be quenched.

[0019] Step 4: After quenching is completed, a preset amount of water is sprayed out through the nozzle at one end of the groove, and the inside of the groove is cleaned through the nozzle in the length direction. At the same time, the hydraulic telescopic rod is retracted so that the water outlet plate at the bottom of the top plate is close to the groove. The groove can then be sprayed and cleaned through the water outlet plate. During the spraying process, the water outlet plate can be rotated by the third electric rotating rod to further improve the cleaning efficiency.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, by setting a groove and a clamping mechanism, the metal part to be processed can be placed inside the groove through the clamping mechanism. Since the cross section of the groove is a trapezoid, the inclined surfaces of the inner side walls of the groove will resist and fix the cylindrical metal part, so that the bottom of the cylindrical metal part may not contact the bottom of the groove, which can prevent the metal part itself from overheating and contacting the bottom of the groove, resulting in a high temperature inside the groove, affecting the cooling efficiency during subsequent quenching work.

[0022] 2. In the invention, by setting a roller mechanism, when a plate-shaped metal part is to be processed and it is necessary to quench the metal part by spray quenching to make the metal part harder, the metal part to be processed can be placed in one of the first mounting grooves on the top of the corresponding roller through the second clamping piece. According to the volume of the metal part, multiple rollers can be used to fix the same metal part. During the fixing process, the corresponding third clamping piece can be moved by the fifth electric telescopic rod, so that the two opposite third clamping pieces clamp and fix the metal part inside the first mounting groove; then the top plate can be moved in the vertical direction by the hydraulic telescopic rod, and the corresponding water outlet plate at the bottom of the top plate can spray quench the metal part. During the spraying process, the first electric valve inside the first water outlet can be closed, and the waste water generated by the spraying is discharged from the second water outlet; at this time, the roller can be rotated by the fourth electric rotating rod to make the various parts of the metal part quench more evenly, thereby ensuring the quenching effect; at the same time, the water outlet plate can be rotated at the bottom of the fourth mounting plate by the third electric rotating rod, so that the water outlet plate can be tilted for spraying, and the water outlet plate and the roller can be rotated together to further improve the quenching efficiency.

[0023] 3. In the invention, by setting the first electric slider and the first clamp, when during the process of spray quenching, the clamped and fixed part of the bottom of the metal part is blocked and difficult to spray, the first clamp can be moved in the horizontal direction by the eighth electric telescopic rod, so that the two first clamps clamp and fix the metal part, and then the second electric slider is slid inside the second slide groove, and the position of the first clamp is adjusted by sliding the second electric slider, and then the two first clamps slide together to clamp and fix the metal part, and the metal part is placed in the first mounting groove inside the adjacent idle roller and fixed, and spray quenching is performed again to prevent the clamping part from being blocked and affecting the normal quenching.

The water outlet of the pump is connected to the nozzle 10 through a hose and a water outlet plate 29.

[0049] A processing method for a surface heat treatment device of a mechanical metal part, the processing method further comprises the following steps:

[0050] Step 1: Place the entire device at a predetermined use position and power it on. When the entire device needs to be used to quench a metal part, first slide the first electric slide block 18 inside the first slide slot 7, adjust the vertical position of the second connecting block 22 through the second electric telescopic rod 21, rotate the first electric rotating rod 36 between the second electric telescopic rod 21 and the first connecting block 20, so that the two second clamps 27 at the bottom of the second mounting plate 24 can clamp and fix the metal part to be processed, and adjust the vertical position of the two second clamps 27 through the fourth electric telescopic rod 25, so that the second clamps 27 can clamp and fix the metal part to be processed at any position, and move the metal part to the groove 9 at the top of the box body 1 for quenching.

[0051] Step 2: Close the first water outlet 12 and each second water outlet 30, and spray a preset amount of water toward the inside of the groove 9 through the corresponding water outlet plate 29. When the metal part is placed in the groove 9, quenching can begin. During the quenching process, each roller 32 can be rotated by the corresponding fourth electric rotating rod, so that the roller 32 can rotate the metal part through rolling friction to improve the quenching efficiency;

[0052] Step 3: Open the first water outlet 12, and the quenched water will flow into the water tank 4 from the first water outlet 12 to temporarily collect the waste water, and then the waste water can be discharged through the drain at the bottom of the water tank 4. When the metal part to be processed is large in size, the metal part to be processed can be clamped and fixed by the second clamp 27, and then the metal part can be placed in the chamber away from the first water outlet 12, and the metal part can be clamped and fixed by the second clamp 27 to quench the metal part;

[0053] Step 4: After quenching is completed, a preset amount of water is sprayed out through the nozzle 10 at one end of the groove 9, and the inside of the groove 9 is cleaned in the length direction through the nozzle 10. At the same time, the hydraulic telescopic rod 3 is retracted so that the water outlet plate 29 at the bottom of the top plate 6 is close to the groove 9. Then, the groove 9 can be sprayed and cleaned through the water outlet plate 29. During the spraying process, the cleaning efficiency can be further improved by rotating the water outlet plate 29 through the third electric rotating rod.

[0054] In the present invention, when the user needs to use the device as a whole, the device as a whole is placed in a predetermined use position and powered on. When the device as a whole needs to be used to quench a metal part, the first electric slider 18 is first slid inside the first slide groove 7 to adjust the horizontal positions of the first connecting block 20 and the second mounting plate 24. The second electric telescopic rod 21 can be used to adjust the vertical position of the second connecting block 22, and the first electric rotating rod 36 between the second electric telescopic rod 21 and the first connecting block 20 is rotated so that the two second clamps 27 at the bottom of the second mounting plate 24 can clamp and fix the metal part to be processed. At the same time, the horizontal position of the second mounting plate 24 can be adjusted by the third electric telescopic rod 23, and the vertical position of the two second clamps 27 can be adjusted by the fourth electric telescopic rod 25, so that the second clamps 27 can clamp and fix the metal part to be processed at any position, and move the metal part to the groove 9 at the top of the box body 1 for quenching.

[0055] When the metal part to be processed is placed inside the groove 9 and the shape of the metal part is cylindrical, since the cross-section of the groove 9 is trapezoidal, the inclined surfaces of the two side walls inside the groove 9 will resist and fix the cylindrical metal part, so that the bottom of the cylindrical metal part does not contact the bottom of the groove 9, which can prevent the metal part itself from overheating and contacting the bottom of the groove 9, resulting in a high temperature inside the groove 9, affecting the cooling efficiency during subsequent quenching work. At the same time, the various rolling mechanisms 11 inside the groove 9 can play a certain supporting role to ensure that the bottom of the metal part does not contact the bottom of the groove 9, and then the quenching process of the metal part can be started.

[0056] When quenching a cylindrical metal part, the first electric valve inside the first water outlet 12 and the second electric valve inside each second water outlet 30 can be closed in advance, and then a certain amount of water is sprayed toward the inside of the groove 9 through the corresponding water outlet plate 29, so that the groove 9 can be used as a water reservoir, and when the subsequent cylindrical metal parts are placed in the groove 9, quenching can begin; during the quenching process, each roller 32 can be rotated by the corresponding fourth electric rotating rod, so that the roller 32 can rotate the metal parts through rolling friction to improve the quenching efficiency. At the same time, after the roller 32 rotates, it can also stir the water inside the groove 9 to a certain extent, thereby improving the flow effect of the water inside the groove 9, and then further improving the quenching efficiency. After the subsequent quenching is completed, the metal part can be taken out from the inside of the groove 9 through the second clamp 27; when the water temperature inside the groove 9 reaches a certain level or the water inside the groove 9 needs to be discharged when changing the spray quenching, the first electric valve and the second electric valve are opened, so that the first water outlet 12 and the second water outlet 30 can discharge the water inside the groove 9, which is convenient for the subsequent quenching of the remaining metal parts, and can also prevent the water inside the groove 9 from having a high temperature after quenching, and the repeated use affects the quenching efficiency. In addition, during the actual use of the device as a whole, multiple metal parts can be placed in the same groove 9 for simultaneous processing, which can improve work efficiency and ensure the normal progress of quenching work.

[0057] When quenching the block-shaped metal part, repeat the placement operation of the second clamp 27 to place the metal part inside the groove 9. Since the cross-section of the groove 9 is a trapezoid, the inclined surfaces of the two side walls inside the groove 9 will resist and fix the block-shaped metal part. At the same time, the rolling mechanism 11 can also support the bottom of the metal part. Then, when the first water outlet 12 and the second water outlet 30 are closed, the block-shaped metal part can be quenched inside the groove 9.

[0058] In addition, when the metal part is quenched inside the groove 9 and the water needs to be discharged, the first water outlet 12 is opened, and the quenched water will flow into the water tank 4 from the first water outlet 12 to temporarily collect the waste water, and the waste water can be discharged later through the drain port at the bottom of the water tank 4; at the same time, the baffle 13 isolates the water tank 4 into two independent chambers, the chamber close to the first water outlet 12 is used to collect waste water, and the chamber away from the first water outlet 12 is used for quenching processing of metal parts. When the volume of the metal part to be processed is large, the metal part to be processed can be clamped and fixed by the second clamp 27, and then the metal part can be placed in the chamber away from the first water outlet 12, and the metal part can be clamped and fixed by the second clamp 27 to be quenched.

[0059] When a plate-shaped metal part is to be processed and it is necessary to use jet quenching to quench the metal part to make the metal part harder, the metal part to be processed can be inserted into one of the first mounting grooves 33 on the top of the corresponding roller 32 through the second clamping piece 27. After the corresponding first mounting grooves 33 of multiple rollers 32 are aligned according to the volume of the metal part, multiple rollers 32 can fix the same metal part. During the fixing process, the corresponding third clamping piece 34 can be moved by the fifth electric telescopic rod 38, so that the two opposite third clamping pieces 34 clamp and fix the metal part inside the first mounting groove 33. ; Afterwards, the top plate 6 can be moved in the vertical direction by the hydraulic telescopic rod 3, and the corresponding water outlet plate 29 at the bottom of the top plate 6 can spray and quench the metal parts. During the spraying process, the first electric valve inside the first water outlet 12 can be closed, and the waste water generated by the spraying is discharged from the second water outlet 30; at this time, the roller 32 can be shaken by the fourth electric rotating rod to make the various parts of the metal parts quench more evenly, thereby ensuring the quenching effect; at the same time, the water outlet plate 29 can also be rotated at the bottom of the fourth mounting plate 28 by the third electric rotating rod, so that the water outlet plate 29 can be tilted for spraying, and the joint rotation of the water outlet plate 29 and the roller 32 can further improve the quenching efficiency. When the plate-shaped metal component is immersed in the groove 9 for immersion quenching, and the metal component can contact the roller 32 at the bottom, the rotation of the roller 32 at the bottom of the metal component can also drive the metal component to shake and deflect to a certain extent, so that the metal component is quenched more comprehensively; therefore, when the plate-shaped metal component is small in size, the roller 32 can make the corresponding metal component have a higher hardness after quenching, and the small-volume metal component is safer during actual use.

[0060] When during the process of spray quenching, the clamped and fixed part at the bottom of the metal component is blocked and difficult to spray, the first clamp 14 can be moved in the horizontal direction by the eighth electric telescopic rod, so that the two first clamps 14 clamp and fix the metal component, and then the second electric slider 16 is slid in the second slide groove 15, and the position of the first clamp 14 is adjusted by sliding the second electric slider 16, and then the two first clamps 14 slide together to clamp and fix the metal component, and the metal component is placed in the first mounting groove 33 in the adjacent idle roller 32 and fixed, and spray quenching is performed again to prevent the clamping part from being blocked and affecting the normal quenching.

[0061] In addition, when the plate to be processed is large in size and the first mounting groove 33 on the outer wall of the roller 32 cannot fix the metal part due to size problems, two groups of four first clamps 14 can be used to fix a metal part together, and then the metal part can be sprayed and quenched through the water outlet plate 29. When the clamping part is blocked and cannot be quenched during the quenching process, two of the first clamps 14 can be slid through the second electric slider 16 to clamp and fix the part of the metal part that has been quenched, and then the other two first clamps 14 are also slid and adjusted to clamp and fix the part of the metal part that has been clamped, and then the metal part is continued to be quenched through the water outlet plate 29, so that all parts of the metal part can be quenched and the quenching efficiency can be guaranteed. In addition, according to the size of the metal part, the position of the first mounting plate 8 can be adjusted in the vertical direction through the seventh electric telescopic rod to meet the quenching needs of metal parts of different sizes.

[0062] After multiple quenching processes, the impurities retained in the groove 9 accumulate to a certain extent, and the impurities will affect the subsequent quenching work. When the impurities in the groove 9 need to be cleaned, a certain amount of water can be sprayed through the nozzle 10 at one end of the groove 9 to clean the inside of the groove 9 through the nozzle 10 in the length direction. At the same time, the hydraulic telescopic rod 3 can be retracted to make the water outlet plate 29 at the bottom of the top plate 6 close to the groove 9, and then the groove 9 can be sprayed and cleaned through the water outlet plate 29. During the spraying process, the cleaning efficiency can be further improved by rotating the water outlet plate 29 by the third electric rotating rod to prevent the impurities retained on the inclined surface of the groove 9 from being unable to be cleaned due to the trapezoidal cross-section of the groove 9. The cleaned waste water can be directly discharged into the water tank 4 through the first water outlet 12 for collection.

[0063] When the shape of the metal part is irregular, the metal part to be processed can be clamped and fixed by the second clamping piece 27, and then the second electric rotating rod 37 between the third electric telescopic rod 23 and the second mounting plate 24 is rotated, and then the metal part is quenched by spraying water through the water outlet plate 29. After the second mounting plate 24 is rotated by the second electric rotating rod 37, various parts of the metal part can be quenched to prevent the quenching efficiency from being low due to the irregular shape of the metal part during actual operation. At the same time, the immersion quenching form can also be selected according to the processing requirements of the metal part. In actual use, the overall application range of the device is relatively wide.

[0064] When all quenching work is completed, the fifth electric rotating rod between the fourth connecting block 35 and the top plate 6 can be rotated to remove the top plate 6 from the top of the box body 1, so that subsequent staff can thoroughly clean the inside of each groove 9 to improve cleaning efficiency.
