The system includes a base plate, a heating coil mounted on the top of the base plate, a reset conveyor belt mechanism mounted on one side of the heating coil, a telescopic cylinder mounted at the bottom of the reset conveyor belt mechanism, and a first translational conveyor belt mechanism and a second translational conveyor belt mechanism mounted above the reset conveyor belt mechanism. This invention first heats the housing using the heating coil, then transports the housing to a positioning mold for quenching. The wall of the positioning mold is filled with low-temperature cooling oil, which rapidly cools the housing inside the mold. Upon completion of cooling, tempering is directly performed.

Description

Technical Field

[0001] This invention relates to the field of compressor housing processing, specifically to an intelligent heat treatment system and method for compressor housings. Background Technology

[0002] The compressor housing machining process is a complex process involving multiple steps, designed to ensure that the compressor structure has high precision, meets dimensional requirements, and has stable strength. It is divided into several steps, including material preparation, cutting, stamping, welding, and finishing. Finishing includes processes such as grinding, drilling, and heat treatment. These finishing processes can ensure the strength and precision of the compressor housing structure, so that it meets the technical requirements.

[0003] The heat treatment process in the finishing process is generally divided into three steps: Annealing: After material cutting and preliminary processing, annealing is performed. Annealing usually involves uniform heating, holding, and cooling to reduce the hardness and improve the toughness of the material, making the material structure more uniform; Quenching: After annealing, quenching is performed. Quenching is a rapid cooling process that gives the material higher hardness and wear resistance. The quenching process requires strict control of the heating, holding, and cooling rates to meet the requirements of different materials and specifications; Tempering: After quenching, tempering is performed to reduce the brittleness of the material and improve its toughness. Tempering generally involves uniform heating, holding, and cooling to adjust and stabilize the material structure.

[0004] In the actual heat treatment process of compressor housing, quenching is usually done by directly immersing the housing in oil for cooling, and then moving it to another heating process for heating. However, in this case, direct oil quenching will result in a large amount of cooling oil adhering to the surface of the housing, making it inconvenient to clean the surface. An additional process for surface treatment is required, which is time-consuming and labor-intensive. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an intelligent heat treatment system and method for compressor housing, so as to solve the technical problem that the surface of the compressor housing will be covered with a large amount of cooling oil due to the quenching of the housing by cooling oil, and the surface of the housing will be difficult to clean.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent heat treatment system for a compressor housing, comprising a base plate, a heating coil mounted on the top of the base plate, a reset conveyor belt mechanism mounted on one side of the heating coil, a telescopic cylinder mounted at the bottom of the reset conveyor belt mechanism, a first translational conveyor belt mechanism and a second translational conveyor belt mechanism mounted above the reset conveyor belt mechanism, an insulated conveyor belt mounted below the second translational conveyor belt mechanism, and positioning molds mounted on the surfaces of the reset conveyor belt mechanism and the first translational conveyor belt mechanism. The positioning molds include an upper mold, a lower mold, an electromagnetic lock, and heating rods. The upper mold is slidably connected to the surface of the first translational conveyor belt mechanism, and the lower mold is disposed on the surface of the reset conveyor belt mechanism. Multiple heating rods are installed in the inner space of the upper mold and the lower mold, and the upper mold and the lower mold are connected by an electromagnetic lock.

[0007] The present invention is further configured such that a set of vertical conveyor belt mechanisms is installed between the first translational conveyor belt mechanism and the second translational conveyor belt mechanism, and the vertical conveyor belt mechanisms are respectively located at both ends of the heat-insulating conveyor belt.

[0008] The present invention is further configured such that the heat-insulating conveyor belt and the vertical conveyor belt mechanism are connected by a worm gear mechanism.

[0009] The present invention is further configured such that the surface of the reset conveyor belt mechanism is provided with a plurality of stops, the surfaces of the first translation conveyor belt mechanism and the second translation conveyor belt mechanism are provided with a plurality of limiting strips, and the top of the upper mold is provided with a limiting groove that matches the limiting strips.

[0010] The present invention is further configured such that the positioning mold includes contact pieces, temperature detection sensors, and a power supply mechanism. The contact pieces are respectively installed on the surfaces of the upper mold and the lower mold, and the contact pieces of the upper mold and the lower mold correspond one-to-one. Temperature detection sensors are installed inside the upper mold and the lower mold. The temperature detection sensor of the upper mold detects the temperature of the inner wall space of the upper mold, and the temperature detection sensor of the lower mold detects the temperature of the inner wall space of the lower mold. A power supply mechanism is installed inside the wall of the upper mold.

[0011] The invention is further configured such that a cylinder is mounted on one side of the heating coil, and a fork is connected to the output end of the cylinder.

[0012] The present invention is further configured such that a fixed shell is installed on the top of the base plate, a cooling box is installed on the outer wall of the fixed shell, and the cooling box is connected to the interior of the fixed shell through an oil supply pipe.

[0013] The present invention is further configured such that multiple sets of circulation pipes are installed on the side wall of the fixed shell, each set of circulation pipes is distributed from top to bottom, and multiple connecting pipes are installed on the side walls of the upper mold and the lower mold, the positions of the connecting pipes correspond one-to-one with the positions of the circulation pipes.

[0014] The invention is further configured such that a plug is fixedly installed inside the circulation tube, a guide rod is installed on one side of the fixing block on the inner wall of the connecting tube, a sealing ball is installed on the movable end of the guide rod, and a spring is connected between the sealing ball and the fixing block.

[0015] This invention also provides the following technical solution: a method for using an intelligent heat treatment system for a compressor housing, the specific operation steps of which are as follows:

[0016] Step 1: First, heat the compressor housing with a heating coil to quickly raise the temperature of the compressor housing to the required quenching temperature;

[0017] Step 2: The heated compressor housing is transported to the positioning mold position, where it is quenched by the low-temperature cooling oil inside the positioning mold.

[0018] Step 3: After quenching, the heating rods inside the positioning mold are used to directly temper and heat the internal compressor housing;

[0019] Step 4: After tempering, remove the compressor housing, replace the oil inside the positioning mold, and move the positioning mold to the initial position. Repeat Step 1.

[0020] In summary, the present invention has the following advantages: The present invention first heats the shell using a heating coil, then transports the shell to a positioning mold for quenching. The wall of the positioning mold is filled with low-temperature cooling oil, which rapidly cools the shell inside the positioning mold. Upon completion of cooling, tempering is directly performed. During this process, heating rods inside the positioning mold heat the shell. Since heat is conducted to the inner shell through the oil, the shell is heated uniformly. Furthermore, the oil does not directly contact the shell during quenching and tempering, thus reducing the need for subsequent surface treatment. During the cooling process of the inner shell, various conveyor belt mechanisms drive the positioning mold in a cyclical motion, circulating the oil inside the positioning mold for future reuse.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] A smart heat treatment system for compressor housing, such as Figure 1-8 As shown, the device includes a base plate 1, with a heating coil 2 mounted on the top of the base plate 1. The heating coil 2 is electromagnetically heated, allowing the compressor housing to be directly inserted into the heating coil 2 for rapid heating to the required quenching temperature. A cylinder 20 is mounted on one side of the heating coil 2, and a fork 21 is connected to the output end of the cylinder 20. The compressor housing is placed on the fork 21, and the cylinder 20 pushes the fork 21 forward to the position of the heating coil 2 for heating. After heating is completed, the cylinder 20 continues to push the fork 21 forward to the position of the positioning mold 4, ready for quenching.

[0032] The positioning mold 4 is divided into two parts: an upper mold 401 and a lower mold 402. The upper mold 401 is slidably connected to the surface of the first translational conveyor belt mechanism 5. The surface of the first translational conveyor belt mechanism 5 is provided with multiple limiting strips 18. The top of the upper mold 401 is provided with a limiting groove that matches the limiting strip 18. That is, the upper mold 401 is slidably connected to the first translational conveyor belt mechanism 5 by inserting into the limiting strip 18 through the limiting groove. The lower mold 402 is placed on the surface of the reset conveyor belt mechanism 3. A telescopic cylinder 17 is installed at the bottom of the reset conveyor belt mechanism 3. When the cylinder 20 continues to push the fork 21 forward to the space between the upper mold 401 and the lower mold 402, the telescopic cylinder 17 is activated. The push plate at the movable end of the telescopic cylinder 17 pushes the lower mold 402 upward. When the lower mold 402 contacts the compressor housing, the cylinder 20 retracts, retracts the fork 21, and causes the compressor housing to fall into the lower mold 402. At this time, the telescopic cylinder 17 continues to push the lower mold 402 upward until it contacts the upper mold 401. The electromagnetic lock 403 then fixes the upper mold 401 and the lower mold 402 together.

[0033] Since the upper mold 401 and the lower mold 402 have spaces inside their walls, and these spaces are filled with low-temperature cooling oil, the high-temperature compressor housing undergoes quenching when it enters the positioning mold 4, causing the compressor housing to cool down rapidly. At this time, since the upper mold 401 and the lower mold 402 are locked, the first translational conveyor belt mechanism 5 at the top of the base plate 1 is activated, pushing the positioning mold 4 to one side until the housing inside the positioning mold 4 is quenched. The completion of the housing quenching is indicated by the temperature detection sensor 406. Temperature detection sensors 406 are installed inside both the upper mold 401 and the lower mold 402. The temperature detection sensor 406 of the upper mold 401 detects the temperature of the inner wall space of the upper mold 401, and the temperature detection sensor 406 of the lower mold 402 detects the temperature of the inner wall space of the lower mold 402. When the temperature detection sensor 406 of the upper mold 401 detects that the temperature has dropped to the quenching set value, the positioning mold 4 moves to the position of the vertical conveyor belt mechanism 8.

[0034] A set of vertical conveyor belt mechanisms 8 is installed between the first translational conveyor belt mechanism 5 and the second translational conveyor belt mechanism 6. The vertical conveyor belt mechanisms 8 are located at both ends of the heat-insulating conveyor belt 7. The surface of the vertical conveyor belt mechanism 8 is provided with multiple push bars. The push bars fix the position of the positioning mold 4. After the vertical conveyor belt mechanism 8 is started, the push bars push the positioning mold 4 to move forward. When the positioning mold 4 moves to the position of the vertical conveyor belt mechanism 8, that is, when the positioning mold 4 is located between the two push bars, the vertical conveyor belt mechanism 8 is started. The push bars push the positioning mold 4 to move forward, so that the positioning mold 4 disengages from the limiting bar 18 of the first translational conveyor belt mechanism 5 and inserts into the limiting bar 18 of the second translational conveyor belt mechanism 6. When the positioning mold 4 completely disengages from the limiting bar 18 of the first translational conveyor belt mechanism 5, the positioning mold 4 reaches the heat-insulating conveyor belt 7 at the top of the bottom plate 1. At this time, the positioning mold 4 performs tempering work on the internal compressor housing.

[0035] Multiple heating rods 405 are installed in the inner space of the upper mold 401 and the lower mold 402. When the heating rods 405 are activated, the oil in the inner space is rapidly heated to heat the shell and temper it. The heat conduction of the oil is stable and uniform, which can provide better heat preservation for the inner shell. The temperature and time of heat preservation are controlled and realized by the temperature detection sensor 406 and the controller. The temperature detection sensor 406 and the controller are existing technologies, which are intended to provide feedback on the oil temperature and the temperature of the inner space and select the appropriate time and temperature range according to the material. Therefore, they are not described in detail. Those skilled in the art can select the appropriate temperature monitoring and time control mechanism as needed to carry out intelligent heat treatment. The shape of the heat preservation conveyor belt 7 is Z-shaped. When the positioning mold 4 is located on the top plane of the heat preservation conveyor belt 7, it is the tempering stage.

[0036] Furthermore, a power supply mechanism 407 is installed inside the wall of the upper mold 401. Contact pieces 404 are respectively installed on the surfaces of the upper mold 401 and the lower mold 402. The contact pieces 404 of the upper mold 401 and the lower mold 402 correspond one-to-one. The circuit between the upper mold 401 and the lower mold 402 is connected through the contact pieces 404. The circuit is connected to the temperature detection sensor 406 and the heating rod 405 and is powered by the power supply mechanism 407. The power supply mechanism 407 can be a battery connected to the external circuit.

[0037] After tempering, the second translational conveyor belt mechanism 6 and the insulation conveyor belt 7 start synchronously, pushing the positioning mold 4 to one side. At this time, the electromagnetic lock 403 unlocks, and the upper mold 401 and lower mold 402 unlock. The second translational conveyor belt mechanism 6 and the insulation conveyor belt 7 push the upper mold 401 and lower mold 402 to one side respectively until they reach the position of the vertical conveyor belt mechanism 8 on the other side. At this time, the shell inside the lower mold 402 is removed, and then the vertical conveyor belt mechanism 8 is started. The push bar on the surface of the vertical conveyor belt mechanism 8 pushes the upper mold. 401 and the lower mold 402 move toward the direction of the first translational conveyor belt mechanism 5. The upper mold 401 disengages from the limiting strip 18 of the second translational conveyor belt mechanism 6 and inserts into the limiting strip 18 of the first translational conveyor belt mechanism 5. The surface of the reset conveyor belt mechanism 3 is provided with multiple stops 19. Under the push of the vertical conveyor belt mechanism 8, the lower mold 402 reaches the surface of the reset conveyor belt mechanism 3 and is located between the stops 19, ready to circulate the oil inside the upper mold 401 and the lower mold 402 and replace the low-temperature cooling oil.

[0038] A fixed shell 9 is installed on the top of the base plate 1. A cooling box 10 is installed on the outer wall of the fixed shell 9. The cooling box 10 is connected to the interior of the fixed shell 9 through an oil supply pipe 11. Multiple sets of circulation pipes 12 are installed on the side wall of the fixed shell 9. Each set of circulation pipes 12 is distributed from top to bottom. Multiple connecting pipes 14 are installed on the side wall of the upper mold 401 and the lower mold 402. The positions of the connecting pipes 14 correspond one-to-one with the positions of the circulation pipes 12. Inserted posts 13 are fixedly installed inside the circulation pipes 12. A guide rod is installed on one side of the fixed block on the inner wall of the connecting pipe 14. A sealing ball 15 is installed on the movable end of the guide rod. A spring 16 connects the sealing ball 15 and the fixed block. When it is necessary to replace the low-temperature cooling oil, the vertical conveyor belt mechanism 8 pushes the upper mold 401 and the lower mold 402 to move a certain distance towards the fixed shell 9, so that the connecting pipes 14 is inserted into the circulation pipe 12. A sealing structure is provided between the outer wall of the connecting pipe 14 and the inner wall of the circulation pipe 12, so that a relative seal can be obtained after the connecting pipe 14 is inserted. After the connecting pipe 14 is inserted, the insert 13 pushes the sealing ball 15 inward, causing the spring 16 to contract and release the seal of the sealing ball 15 on the connecting pipe 14. At this time, the upper mold 401, the lower mold 402 and the fixed shell 9 are in a connected state. An oil pump is installed in the middle of the circulation pipe 12. The oil pump draws the high temperature oil inside the upper mold 401 and the lower mold 402 into the fixed shell 9 and sends the low temperature oil into the upper mold 401 and the lower mold 402. The oil inlet and oil outlet of the circulation pipe 12 are both equipped with a one-way valve structure to prevent the oil from flowing back. The high temperature oil is drawn into the cooling box 10 through the pump body of the oil delivery pipe 11 for cooling in preparation for subsequent use.

[0039] Furthermore, a vision camera is installed on the side wall of the fixed shell 9 facing the first translational conveyor belt mechanism 5. The vision camera is used to detect the inside of the lower mold 402 to prevent the shell after tempering from being left unremoved.

[0040] After the low-temperature oil replacement is completed, the upper mold 401 and lower mold 402 move back one distance by the vertical conveyor belt mechanism 8, causing the connecting pipe 14 to disengage from the circulation pipe 12. The insert 13 stops pressing on the sealing ball 15, the spring 16 returns to its original position, and pushes out the sealing ball 15 to seal the connecting pipe 14. At this time, the upper mold 401 and lower mold 402 are returned to their initial positions by the first translational conveyor belt mechanism 5 and the reset conveyor belt mechanism 3, in preparation for the next compressor housing to be quenched and tempered.

[0041] Above the reset conveyor belt mechanism 3, a first translation conveyor belt mechanism 5 and a second translation conveyor belt mechanism 6 are installed. Below the second translation conveyor belt mechanism 6, an insulated conveyor belt 7 is installed. The insulated conveyor belt 7 and the vertical conveyor belt mechanism 8 are connected by a worm gear mechanism 22. Therefore, when the insulated conveyor belt 7 is running, the vertical conveyor belt mechanism 8 can run synchronously.
