Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat treatment, and particularly relates to a heat treatment and tempering line for thrust rod. BACKGROUND

[0002] As a key load-bearing transmission component in the automobile suspension system and the engineering machinery transmission system, the mechanical properties of the thrust rod determine the driving safety, the control stability and the service life of the vehicle or equipment. In the actual working condition, the thrust rod needs to bear alternating loads, impact loads and torsional moments for a long time, so it has strict requirements on the strength, hardness, toughness and fatigue life. The core process of improving the comprehensive mechanical properties of the thrust rod material by the heat treatment and tempering process is to control the heating temperature, the holding time, the cooling rate and the tempering parameters, so that the thrust rod can obtain uniform sorbite structure and meet the use requirements under complex working conditions.

[0003] In the traditional heat treatment and tempering process of the thrust rod, the mesh belt conveyor is the carrier of the series production process, and the specific process is as follows: first, the mesh belt carries the thrust rod to be processed into a continuous heating furnace, the furnace temperature is accurately controlled at 850-950 DEG C, and the temperature is kept for 1-2 hours to ensure that the workpiece organization is completely austenitized, laying a foundation for quenching; after heating, the mesh belt does not need to be additionally transported, and the high-temperature thrust rod is directly sent into the quenching tank, the workpiece is cooled to below 200 DEG C in the quenching medium, and the hardness is improved by rapid cooling to form martensite; after quenching, the mesh belt continues to send the workpiece into the tempering furnace, the furnace temperature is adjusted to 500-600 DEG C, and the temperature is kept for 2-3 hours, so that the martensite is converted into sorbite, the internal stress is reduced, the toughness is improved, and brittle fracture is avoided; after tempering, the mesh belt slowly transports the workpiece to ensure uniform cooling and prevent performance fluctuations or deformation caused by rapid cooling and uneven cooling.

[0004] However, in the actual production process, the mesh belt conveyor is prone to problems caused by the accumulation of pollutants. On the one hand, a small amount of quenching oil will be left on the surface of the thrust rod after quenching, and these oil stains will gradually adhere to the surface of the mesh belt during the conveying process of the workpiece; the adhered oil stains are easily carbonized in the high-temperature environment of the heating furnace and the tempering furnace, and finally form hard scale on the surface of the mesh belt. On the other hand, the high temperature in the heating furnace will cause the surface of the thrust rod to produce oxide scale, part of which will fall off from the surface of the workpiece and accumulate in the grid gap of the mesh belt. These scales and scales will directly contaminate the subsequent thrust rods transported by the mesh belt, not only causing obvious oil stain spots or oxide scale indentation marks on the surface of the workpiece, but also greatly increasing the difficulty of the subsequent cleaning process; if the cleaning is not thorough, the residual pollutants will also affect the uniformity of the workpiece during the tempering process, and finally affect the mechanical properties of the thrust rod after tempering. Therefore, a heat treatment and tempering line for thrust rod needs to be designed.

[0047] And the cover on the conveying assembly 1 is provided with a continuous heating furnace 2, which can uniformly and continuously heat the push rod on the conveying mesh belt 12, providing temperature conditions for subsequent quenching treatment; and a quenching pool 3 is arranged at one end position of the conveying assembly 1, and the heated push rod is conveyed into the quenching pool 3 to complete the quenching process, change the metallographic structure of the push rod, and improve its hardness and other performances; meanwhile, a tempering furnace 4 is still arranged on one side of the quenching pool 3 and covers the conveying assembly 1, and the quenched push rod is conveyed into the tempering furnace 4 through the conveying assembly 1 to perform tempering treatment, so as to eliminate the internal stress generated by quenching, stabilize the structure and size of the push rod, and make the push rod obtain good comprehensive mechanical properties. In the actual push rod production heat treatment scene, such a continuous quenching and tempering line structure can ensure that the push rod sequentially passes through the heating, quenching, tempering and other processes, guarantee the consistency and stability of the heat treatment quality, and meet the strict requirements of the push rod on the mechanical properties.

[0048] Referring to Figures 2-6 The cleaning assembly 5 is arranged on the conveying assembly 1, which is used for cleaning and maintaining the conveying mesh belt 12 to guarantee the stability of the conveying process and the cleanliness of the conveyed articles. The cleaning assembly 5 comprises a cleaning brush part 51 arranged on the mounting frame 11, and the cleaning brush part 51 comprises a concave-shaped frame 511 fixed on the mounting frame 11, an air cylinder 512 fixed on the upper bottom surface of the concave-shaped frame 511, an output end of the air cylinder 512 penetrating through the concave-shaped frame 511, a support frame 513 in a concave structure fixed on the extension end of the air cylinder 512, a cleaning brush 519 connected by bearings between the inner walls of the support frame 513, the cleaning brush 519 being made of nylon wire, the bearing connection mode enabling the cleaning brush 519 to rotate flexibly, the cleaning brush 519 being provided with a brush shaft for transmitting rotating power, and a motor two 518 fixed on the side surface of the support frame 513, an output end of the motor two 518 being connected with one end of the cleaning brush 519 through a shaft coupling.

[0049] Meanwhile, two groups of supporting plates 515 are fixed on both sides of the concave-shaped frame 511, and four groups of the supporting plates 515 jointly connect and fix a cleaning box 514, the cleaning box 514 storing a special cleaning agent inside for cleaning the cleaning brush 519, and a valve (not shown in the figure) is communicated at the bottom of the cleaning box 514 and connected with external equipment through a hose. In the initial state, the air cylinder 512 is in the unstarted state, at this time, the local position of the cleaning brush 519 is located inside the cleaning box 514 and in contact with the cleaning agent in the cleaning box 514, and the cleaning brush 519 can always be kept in a clean state by means of the motor two 518. In addition, a waist groove (not shown in the figure) adapted to the movement of the brush shaft is formed on both sides of the cleaning box 514, and the waist groove provides sufficient movement space for the lifting of the brush shaft, avoiding the hindrance of the brush shaft in the movement process.

[0050] In addition, the four groups of supporting plates 515 are connected with a shielding part at one end, which is used to shield the impurities falling from the conveying mesh belt 12 when the cleaning brush 519 is not working. The shielding part includes two groups of symmetrically distributed shielding plates 516 arranged at the upper end of the four groups of supporting plates 515, and the surface of the shielding plate 516 is provided with an inclined groove, which is beneficial to guide the falling impurities. The horizontal end bottom surface of the bottom surface of the shielding plate 516 is fixed with a guide rail 517, while the top end of the supporting plate 515 is fixed with a contact rod (not marked in the figure) matched with the guide rail 517, and the two groups of shielding plates 516 are respectively slidably connected with the contact rods at the top end of the two groups of same-side supporting plates 515. This kind of sliding connection can make the shielding plate 516 slide smoothly, so as to realize the adjustment of the shielding range.

[0051] In addition, the two sides near the two ends of the support frame 513 are fixed with L-shaped friction rods 520, which play a transmission role during the lifting of the support frame 513. The two sides at the two ends of the cleaning box 514 are fixed with side blocks 521, and a rotating shaft 522 is arranged on the side block 521 through a bearing. The two ends of the rotating shaft 522 are fixed with friction wheels 523, which transmit power by friction. Among them, the two groups of friction wheels 523 symmetrically arranged on the two groups of rotating shafts 522 are in contact with the surface of the friction rod 520, and the other two groups of friction wheels 523 are respectively in contact with the bottom surface of the two groups of shielding plates 516.

[0052] When the air cylinder 512 drives the support frame 513 to lift, the friction rod 520 drives the rotating shaft 522 to rotate through the contact with the friction wheel 523, so that the friction wheel 523 in contact with the shielding plate 516 rotates, and finally the shielding plate 516 slides. Specifically, at the beginning, one side of the two groups of shielding plates 516 is in a state of mutual adhesion, and with the sliding, it gradually changes to a state of mutual separation of the two groups of shielding plates 516. At this time, synchronously, the cleaning brush 519 will gradually extend out of the gap between the two groups of shielding plates 516 and contact the bottom surface of the conveying mesh belt 12. Then, the motor two 518 is started to drive the cleaning brush 519 to rotate, and the rotating direction of the cleaning brush 519 is opposite to the conveying direction of the conveying mesh belt 12. Such reverse rotation design can more effectively remove the impurities on the conveying mesh belt 12 and improve the cleaning effect.

[0053] Reference Figures 6-8As shown, a suction unit 53 is provided on one side of the cleaning unit 51 on the mounting frame 11.

The fan unit 532 has multiple fans, which can form a strong suction airflow. Each fan has a motor shaft 533, which is the power transmission component for the fan rotation. A third motor 534 is fixed to the side of one set of support brackets 531, providing the power source for the rotation of the multiple fans.

[0054] The output end of the motor 534 is fixed with a drive shaft 535. Multiple sets of bevel gears 536, spaced apart, are fixed on the drive shaft 535. The number of bevel gears 536 matches the number of fans in the fan unit 532. A bevel gear 2 is fixed on the motor shaft 533 of each fan, meshing with bevel gear 536. Through this meshing transmission, the power of the motor 534 is transmitted to the motor shafts 533 of each fan, driving them to rotate and achieving synchronous suction. Simultaneously, a herringbone baffle (not shown in the figure) is fixed between the two sets of support frames 531. This baffle shields the multiple sets of bevel gears 536 and bevel gear 2, preventing impurities from entering the transmission components and ensuring the stability and reliability of the transmission. In actual thrust rod heat treatment production, the suction unit 53 and the cleaning unit 51 work together to further clean the conveyor belt 12, creating favorable conditions for stable thrust rod transport and subsequent heat treatment processes.

[0055] like Figures 8-10 As shown, a spraying section 54 is provided on one side of the suction section 53. The spraying section 54 is used to spray a protective agent onto the cleaned conveyor belt 12 to enhance the corrosion resistance and service life of the belt. The spraying section 54 includes a mounting box 541 fixed on the mounting frame 11. The mounting box 541 stores the protective agent and provides a container for the storage and supply of the protective agent. A herringbone plate 542 is fixed on the mounting box 541.

[0057] At the same time, the one-way valve one 555 is communicated with the bottom of the storage tank 545, the one-way valve one 555 is communicated with the external supply device through the hose, which is used for supplementing the protective agent in the storage tank 545; the bottom of the storage tank 545 is also communicated with the one-way valve two, one end of the one-way valve two is connected with the pipeline 546, the pipeline 546 is used for transmitting the protective agent, and the spray pipe 547 is fixed on one end of the pipeline 546, the spray pipe 547 is arranged through the chevron plate 542, one end of the spray pipe 547 has a spray head, and the protective agent is uniformly sprayed on the conveying mesh belt 12 through the spray pipe 547 and the spray head.

[0058] In addition, the plate 543 is fixed on both sides of the installation box 541, the driving part is fixed on the plate 543, the transmission rod 553 is arranged between the two groups of plates 543, and a plurality of worm gears 549 consistent with the number of the turbine 551 are fixed on the transmission rod 553, the worm gears 549 are engaged with the turbine 551, the turbine 551 is driven to rotate by rotating the worm gears 549, and power transmission is realized. At the same time, the reversible motor 544 is fixed on the side of one group of plates 543, the reversible motor 544 is connected with one end of the transmission rod 553 through the shaft coupling, the reversible motor 544 provides power source for the rotation of the transmission rod 553, the rotation direction of the transmission rod 553 can be controlled through the forward and reverse rotation of the reversible motor 544, thereby controlling the rotation direction of the turbine 551, realizing the reciprocating motion of the piston, and completing the suction and spraying action of the protective agent. In actual thrust rod heat treatment production, the spraying part 54 can spray the protective agent in time after cleaning the conveying mesh belt 12, effectively protecting the mesh belt and prolonging the service life of the conveying mesh belt 12, and ensuring long-term operation of the equipment.

[0059] Working principle: when the thrust rod heat treatment is running, the conveying assembly 1 starts first, the motor 131 rotates, through the transmission of the chain wheel 14, chain 15 and chain wheel 2 17, the rotating wheel 16 is rotated, and then the conveying mesh belt 12 is continuously operated. The heat treated thrust rod is placed on the conveying mesh belt 12, and then the mesh belt enters the continuous heating furnace 2, the quenching tank 3 and the subsequent tempering furnace 4 in turn. In the continuous heating furnace 2, the thrust rod is uniformly and continuously heated to reach the temperature required for quenching; then it is conveyed to the quenching tank 3 to complete the quenching process, the metallographic structure is changed, and the hardness and other properties are improved; the quenched thrust rod is sent into the tempering furnace 4 by another set of conveying assembly 1 for tempering treatment to eliminate the internal stress generated by quenching, stabilize the organization and size, and finally obtain good comprehensive mechanical properties;

[0060] When the conveying mesh belt 12 needs to be cleaned and maintained, the cleaning assembly 5 starts to work. The cylinder 512 starts to work, pushes the support frame 513 to rise, at this time, the L-shaped friction rod 520 fixed on the support frame 513 is in contact with the friction wheel 523, drives the rotating shaft 522 to rotate. The friction wheels 523 at both ends of the rotating shaft 522 rotate, on the one hand, the friction wheel 523 in contact with the bottom surface of the shielding plate 516 rotates, and the two groups of shielding plates 516 slide along the contact rod at the top end of the supporting plate 515, gradually changing from the initial state of mutual adhesion to mutual separation, opening the cleaning space; on the other hand, the support frame 513 rises to drive the cleaning brush 519 to extend, so that it is in contact with the bottom surface of the conveying mesh belt 12. Then, the motor 2 518 starts to work, drives the cleaning brush 519 to rotate in the opposite direction of the conveying direction of the conveying mesh belt 12, and the nylon wire material brush is used to efficiently remove the impurities on the mesh belt. At the same time, the motor 3 534 of the suction part 53 operates, through the meshing transmission of the multiple bevel gears 1 536 on the driving shaft 535 and the bevel gears 2 on the fan motor shaft 533, the multiple fans of the fan group 532 rotate synchronously, generating suction airflow to timely remove the impurities remaining on the conveying mesh belt 12 during the cleaning process, and further improving the cleaning effect;

[0061] After cleaning, the spraying part 54 starts to work. The positive and negative motor 544 starts to work, drives the transmission rod 553 to rotate through the coupling, and the multiple worms 549 on the transmission rod 553 rotate synchronously, which meshes with the turbine 551 to drive the turbine 551 to rotate. Since the turbine 551 is in threaded connection with the lead screw 552, the rotation of the turbine 551 drives the lead screw 552 to move, and then drives the piston in the storage tank 545 to move. The piston extrudes the mesh belt protective agent in the storage tank 545, so that it enters the pipeline 546 through the one-way valve 2, and then is uniformly sprayed on the cleaned conveying mesh belt 12 through the spray pipe 547 and the spray head. The one-way valve 1 555 can be connected with the external supply equipment through the hose when needed to supplement the protective agent in the storage tank 545. The sprayed protective agent can enhance the corrosion resistance of the conveying mesh belt 12, effectively prolong its service life, and ensure the long-term stable operation of the equipment;

[0062] When the cleaning and spraying operations are completed, the air cylinder 512 drives the support frame 513 to descend, and the cleaning brush 519 is returned to the cleaning box 514 and contacts the cleaning agent in the box. At the same time, under the driving of the friction rod 520, the friction wheel 523 and other components, the shielding plate 516 slides to close, and the initial shielding state is restored to prevent impurities on the conveying mesh belt 12 from falling into the cleaning box 514. The suction part 53 and the spraying part 54 also stop working, and the entire cleaning assembly 5 returns to the initial state, waiting for the next cleaning and maintenance operation of the conveying mesh belt 12, to ensure that the conveying assembly 1 can always provide stable and clean material conveying guarantee for the thrust rod heat treatment process.

[0063] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application.
