Description

Technical Field

[0001] The present application relates to the technical field of heat treatment of forgings, and in particular to a heat treatment device for forgings and a treatment process thereof. Background Art

[0002] During the heat treatment process of forgings, multiple forgings need to be neatly stacked and placed in a loading frame, and then the loading frame is placed on a transport device, which then transports them to the heat treatment furnace for heat treatment. Figure 1 The loading frame 1 consists of a frame body 11 and ear plates 12 on both sides. A through hole 13 is opened around the frame body 11. A truncated cone-shaped fixing column 14 is fixedly provided at the bottom of the frame body 11. A fixing groove 15 that cooperates with the fixing column 14 is opened on the upper end surface of the frame body 11. Adjacent loading frames 1 are connected by plugging the fixing column 14 and the fixing groove 15.

[0003] Workers need to move the loading frame to the material transport device, but since the forging material is iron, the loading frame filled with forgings is very heavy. When workers move the loading frame, the labor intensity is high and the loading efficiency is low. Summary of the Invention

[0004] In order to reduce the labor intensity of workers in carrying the loading frame and improve the loading efficiency of the loading frame, the present application provides a forging heat treatment equipment and a treatment process thereof.

[0005] On the one hand, the present application provides a forging heat treatment equipment adopting the following technical solution:

[0006] A forging heat treatment equipment, which includes a material transport platform, a quenching furnace, a cleaning furnace and a tempering furnace, and also includes a frame, the frame including a carrier and a guide rail frame; a loading mechanism, the loading mechanism includes a carrier, the carrier is formed with a accommodating cavity for accommodating the carrier, the carrier is used to carry a loading frame, the carrier is provided with a support plate, the support plate is slidably connected to the carrier, and an elastic part is connected between the support plate and the carrier; a material transport mechanism, the material transport mechanism includes a material transport assembly and a drive assembly, the material transport assembly is provided with two groups on both sides of the carrier, each group of the material transport assembly includes a support rod and a pressure rod, the support rod is slidably connected to the guide rail frame, the pressure rod is rotatably connected to the support rod, and the drive assembly is installed on the guide rail frame, and the drive assembly is used to drive the support rod to slide along the length direction of the guide rail frame.

[0007] By adopting the above-mentioned technical solution, the load-bearing frame can provide a accommodating space for the load-bearing vehicle and a basis for loading the load-bearing frame. The guide rail frame can provide a sliding track for the support rod. The support plate and the elastic part can make the load-bearing frame on the support plate always under an upward elastic force, ensuring that the load-bearing frame in the load-bearing vehicle can be in a state of continuous loading. The support rod can support the ear plate of the load-bearing frame and can drive the first layer of the load-bearing frame to move. The pressure rod can make the first layer of the load-bearing frame and the second layer of the load-bearing frame separate from each other, facilitating the movement of the first layer of the load-bearing frame. The driving assembly can drive the support rod to move to transport the load-bearing frame.

[0008] The material transport assembly transports the loading frame to the material transport platform, and the material transport platform then transports the loading frame to the quenching furnace, cleaning furnace or tempering furnace. The quenching furnace can calcine the forgings in the loading frame at high temperature, the cleaning furnace can clean the forgings and quickly cool them down, and the tempering furnace can heat and calcine the forgings here to enhance the structural strength of the forgings.

[0009] The loading frame filled with forgings is placed on the carrier, which is then pushed into the holding cavity within the carrier. When the loading frame needs to be loaded, the drive assembly drives the transport assembly to the carrier position. During this process, the support rod inserts under the ear plate of the first-layer loading frame and contacts the ear plate. The pressure rod presses down the second-layer loading frame, and the support plate moves downward synchronously under the action of the elastic member. The drive assembly drives the transport assembly to move in the opposite direction and reset. During this process, the support rod drives the first-layer loading frame to move synchronously until it is transported to the transport platform. The second-layer loading frame moves upward under the action of the elastic member and support plate.

[0010] Optionally, both ends of the support rod are rotatably connected to rollers, the pressure rod is rotatably provided with a roller at one end away from the support rod, and the guide rail frame is provided with a rolling groove for the roller to roll and a slide rail for the roller to slide.

[0011] By adopting the above technical solution, when the driving component drives the support rod to move, the roller rolls in the rolling groove, thereby ensuring the stability of the support rod during the movement. The anti-roller can increase the downward pressure effect of the pressure rod on the ear plate of the loading frame, ensuring the stability of the downward pressure. When the anti-roller slides in the slide rail, it can further increase the stability of the pressure rod movement.

[0012] Optionally, the slide rail is formed with a downward pressing groove, and when the resisting roller is located in the downward pressing groove, the resisting roller can press the loading frame downward.

[0013] By adopting the above technical solution, the downward pressure groove can change the movement trajectory of the anti-roller, so that the anti-roller can exert a downward pressure on the second-layer loading frame, so that the first-layer loading frame and the second-layer loading frame are separated from each other, thereby ensuring the subsequent movement of the first-layer loading frame.

[0014] Optionally, two pressure rods are provided and are rotatably connected to both ends of the support rod respectively, and a connecting rod is rotatably connected between the two pressure rods.

[0015] By adopting the above technical solution, the two pressure rods can not only increase the downward pressure effect on the second-layer loading frame, but also the two pressure rods are connected to the support rod through the connecting rod to form a four-rod structure, thereby increasing the connection strength between the pressure rods and the support frame.

[0016] Optionally, the support rod is provided with a blocking block and a return spring, the blocking block is slidably connected to the support rod, the support rod is provided with a slot for accommodating the blocking block and the return spring, and the two ends of the return spring are respectively against the inner bottom wall of the slot and the blocking block.

[0017] By adopting the above technical solution, when the support rod needs to drive the first layer of loading frame to move, the card block pops out from the slot under the elastic force of the reset spring and engages with the ear plate. At this time, the support rod moves in the opposite direction to drive the loading frame to move synchronously.

[0018] Optionally, the loading mechanism further includes a limit cylinder and a buffer cylinder both mounted on the frame, the limit cylinder being used to limit the movement of the loading frame, and the buffer cylinder being used to buffer the loading frame.

[0019] By adopting the above technical solution, when the first-layer loading frame and the second-layer loading frame are separated, the limiting cylinder acts on the second-layer loading frame, thereby overcoming the upward elastic force of the elastic part. When the first-layer loading frame is transported out by the material transport assembly, the buffer cylinder acts on the second-layer loading frame, the limiting cylinder piston rod is retracted, and the buffer cylinder piston rod is slowly retracted. The second-layer loading frame slowly moves upward under the action of the buffer cylinder and the elastic part, forming a replacement of the loading frame.

[0020] Optionally, the drive assembly includes a sprocket, a chain and a drive motor, the drive motor is installed on the guide rail frame, the output shaft of the drive motor is coaxially fixedly connected to the sprocket, the sprocket and the chain are engaged with each other for transmission, and both ends of the support rod are fixed on the chain.

[0021] By adopting the above technical solution, when the support rod needs to move, the output shaft of the drive motor rotates and drives the sprocket to rotate synchronously, the sprocket and the chain engage with each other for transmission, and the chain drives the support rod to move synchronously, thereby forming the transportation of the loading frame.

[0022] Optionally, the material transport platform includes a connecting frame plate, a lifting platform, a support seat and a lifting assembly. The end face of the connecting frame plate is provided with a column hole for the fixed column to be plugged in and matched. The lifting platform is rotatably connected to a transmission roller. The connecting plate frame is located at the upper end of the transmission roller and is against the transmission roller. The lifting platform and the support seat are connected through a lifting assembly. The lifting assembly is used to drive the lifting platform to rise and fall. A pulley is provided at the bottom of the support seat. The frame is fixed with a track, and the pulley can roll on the track.

[0023] By adopting the above technical solution, the column holes of the frame plate can be plugged into the fixed columns of the loading frame to receive the loading frame. The lifting assembly acts on the lifting platform to move the lifting platform up and down. The transmission rollers on the lifting platform can reduce the friction between the frame plate and the lifting platform, so that the frame plate can slide smoothly on the lifting platform, facilitating the loading and unloading of the loading frame. The pulleys at the bottom of the support base can roll on the track, facilitating the movement of the support base and making the support base more stable during movement.

[0024] Optionally, the lifting assembly includes a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are rotatably connected in the middle, one end of the first connecting rod is slidably connected to the lifting platform, the other end of the first connecting rod is rotatably connected to the support seat, one end of the second connecting rod is rotatably connected to the lifting platform, and the other end of the second connecting rod is slidably connected to the support seat.

[0025] By adopting the above technical solution, the first connecting rod and the second connecting rod form a scissor-type structure, driving the first connecting rod and / or the second connecting rod to slide, the first connecting rod and the second connecting rod rotate in the middle, and the intersection moves in the vertical direction, thereby forming the lifting of the lifting platform.

[0026] On the other hand, the present application provides a forging heat treatment process using the following technical solutions:

[0027] The following steps are involved:

[0028] S1, transporting the loading frame filled with forgings to the material transport platform via the loading vehicle and the material transport mechanism;

[0029] S2, the transport platform carries the forgings and slides on the track and transports the forgings to the quenching furnace. The quenching furnace heats the forgings to a certain temperature.

[0030] S3, the transport platform transports the hot forgings to the cleaning furnace, which cleans the forgings and cools them quickly;

[0031] S4, the transport platform transports the cooled forgings to the tempering furnace, which heats the forgings again and cools them slowly.

[0032] By adopting the above technical solution, the quenching furnace can heat the forging to above the critical temperature, and then clean it in the cleaning furnace to make it cool rapidly. This can greatly improve the surface hardness of the forging and clean the impurities on the surface of the forging. The tempering furnace can heat the forging to a lower temperature, keep it warm for a period of time, and then slowly cool it down. This can relieve the stress caused by quenching, reduce hardness, and improve toughness and ductility.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The carrier can not only carry multiple loading frames, but also the elastic parts and support plates can ensure that the loading frames always have an upward movement trend to facilitate the loading of materials;

[0035] 2. The support rod can not only support the loading frame, but also form a transportation effect for the loading frame;

[0036] 3. The four-bar mechanism formed by the support rod and the pressure rod can form a downward pressing effect on the second layer loading frame under the limit of the slide rail, so that the first layer loading frame and the second layer loading frame are separated.

[0061] The implementation principles of the embodiments of this application are as follows:

[0062] The forgings are stacked and placed in the loading frame 1, and then the loading frame 1 is placed in the carrier 71. The spring in the carrier 71 is compressed and always has an upward elastic force on the loading frame 1. The insert plate 717 is inserted into the socket 716 to limit the loading frame 1 in the carrier 71, and then the loading trolley is pushed into the accommodating cavity 711 in the carrier frame 22. The rotating door 221 is closed, and the buffer cylinder 73 drives the buffer plate 731 to press down so that the buffer plate 731 is against the loading frame 1. Then the insert plate 717 is pulled out, the buffer cylinder 73 is reset, and the loading frame 1 moves upward under the elastic force of the spring.

[0063] The driving motor 823 rotates forward, and the driving motor 823 drives the chain 822 to rotate through the sprocket 821, and the chain 822 drives the support rod 811 to move, the roller 8111 rolls in the rolling groove 211, and the pressure roller slides in the slide rail 212. When the pressure roller slides into the lower pressure groove 213, the support rod 811 slides to the bottom of the first layer loading frame 1 and supports the first layer loading frame 1. The upper part of the card block 8112 pops out of the card slot under the elastic force of the reset spring 8113 8114, then the block 8112 can form a blocking effect on the ear plate 12 of the first layer loading frame 1, and the anti-roller 8121 will press the ear plate 12 of the second layer loading frame 1 and move it downward, so that the fixing column 14 of the first layer loading frame 1 is disengaged from the fixing groove 15 of the second layer loading frame 1, and the piston rod of the limiting cylinder 72 is extended to allow the limiting column 721 to be inserted into the through hole 13 of the second layer loading frame 1, so that the second layer and below loading frames 1 will not bounce up.

[0064] The driving motor 823 reverses, and the chain 822 drives the support rod 811 to move in the opposite direction. The block 8112 on the support rod 811 causes the first-layer loading frame 1 to move synchronously until it moves above the material transport platform 3. During this process, the buffer cylinder 73 drives the buffer plate 731 to press down and resist against the second-layer loading frame 1. The limiting cylinder 72 drives the limiting column 721 to disengage from the through hole 13 of the second-layer loading frame 1, and then the buffer cylinder 73 drives the buffer plate 731 to move upward and reset. The second-layer loading frame 1 moves upward synchronously under the action of the elastic member 715, and finally forms the first-layer loading frame 1.

[0065] When the first layer loading frame 1 is located above the material transport platform 3, the lifting motor 345 rotates forward, the output shaft of the lifting motor 345 drives the screw rod 343 to rotate, the screw rod 343 drives the slider 344 to move along the length direction of the screw rod 343, the slider 344 drives the second connecting rod 342 to rotate, and then the second connecting rod 342 and the first connecting rod 341 move upward synchronously to make the lifting platform 32 rise, the column hole 331 of the frame plate 33 is plugged into the fixed column 14 of the first layer loading frame 1, the driving motor 823 rotates forward and drives the support rod 811 to move so that the support rod 811 loses its support for the first layer loading frame 1. The lifting motor 345 reverses, and the lifting platform 32 drives the first layer loading frame 1 to move downward synchronously.

[0066] The transport platform 3 moves on the track 23, so that the loading frame 1 on the transport platform 3 is transported to the quenching furnace 4, the cleaning furnace 5 or the tempering furnace 6. When the transport platform 3 is at the position of the quenching furnace 4, the cleaning furnace 5 or the tempering furnace 6, the loading frame 1 can be sent into the furnace manually or by a pushing device.

[0067] The present application discloses a forging heat treatment process, which includes the following steps:

[0068] S1, transporting the loading frame 1 filled with forgings to the material transport platform 3 via the loading vehicle 71 and the material transport mechanism 8;

[0069] S2, the transport platform 3 carries the forgings and slides on the track 23 and transports the forgings to the quenching furnace 4, which heats the forgings to a certain temperature.

[0070] S3, the transport platform 3 transports the hot forgings to the cleaning furnace 5, which cleans the forgings and cools them quickly;
