DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example

[0035] This embodiment is intended to promote the solution of the problem that after the metal tube has completed the heating and quenching processes, the metal tube is unloaded. When the metal tube rolls through the slope, the metal tube will continue to roll due to inertia, and the metal tubes are prone to collision during rolling. The collision will cause a certain reaction inside the metal tube that has not been completely cooled, thereby affecting the quenching and tempering effect of the metal tube. Please refer to Figure 1-10A quenching and tempering device for metal parts processing includes a heating device 1. The heating device 1 is a prior art and will not be described in detail. The heating device 1 is used to heat a metal tube 2. Appropriate heating can change the crystal structure of the metal and improve its mechanical properties. A quenching device 3 for quenching the metal tube 2 is provided on one side of the heating device 1. The quenching device 3 is a prior art and will not be described in detail. Quenching is a process of hardening the metal by rapidly cooling it, which helps to enhance the hardness and strength of the metal. A quenching device 3 is provided on one side of the quenching device 3 for quenching the treated metal tube 2. The material unloading device 4 is used to unload the material. The metal pipe 2 that has completed tempering can be transferred through the unloading device 4. A supporting component 5 is installed on the unloading device 4 for preventing the metal pipe 2 from rolling down too fast, which helps to prevent the metal pipe 2 from being damaged during the unloading process. The supporting component 5 is connected to a transmission component 6 for transmitting power. The transmission component 6 is connected to a transfer component 7 for transferring and unloading the metal pipe 2. A conveyor belt 8 for transporting the metal pipe 2 to the next processing site is connected below the transfer component 7, which improves production efficiency and ensures smooth progress of the entire processing process.

[0036] In this embodiment: the unloading equipment 4 includes a base 41, on which is a slope 42 with a certain inclination angle, and a limit plate 43 is fixedly connected to the slope 42 for limiting the rolling position of the metal tube 2, which helps to ensure that the metal tube 2 rolls along a predetermined path during the unloading process to avoid deviation from the design requirements, and an auxiliary inclined rod 44 is fixedly connected to the inner side of the slope 42 for assisting in limiting the rolling position of the metal tube 2. This dual rolling position control design can improve the stability of the system and prevent the metal tube 2 from unstable rolling during the unloading process. The limit plate 43 and the auxiliary inclined rod 44 work together to ensure that the metal tube 2 maintains a specific rolling position during the unloading process, thereby making the unloading more precise and controllable.

[0037] In this embodiment: the supporting assembly 5 includes a supporting rod 51 slidably connected to the auxiliary oblique rod 44. This design allows the supporting rod 51 to maintain a relative position as the metal tube 2 rolls during the blanking process. One side of the supporting rod 51 is used to contact the metal tube 2. Through the contact with the supporting rod 51, the metal tube 2 is allowed to roll due to the contact of the supporting rod 51. The rolling speed of the metal tube 2 is limited. The supporting rod 51 is slidably connected to a limiting tube 52 for limiting the position of the supporting rod 51, which helps to ensure that the supporting rod 51 does not deviate from the designed position during the blanking process and maintains a stable supporting effect on the metal tube 2. One end of the limiting tube 52 is fixedly connected to a contact rod 53, and one end of the contact rod 53 is fixedly connected to A spring 54 is connected, and the spring 54 is used to drive the resistance rod 53 to return to its original position. The other end of the spring 54 is fixed inside the base 41. When the metal pipe 2 passes through, the resistance rod 53 can be quickly pulled back to the initial position by the spring 54 to prepare for the next round of material unloading. A rack 55 is provided at the other end of the resistance rod 53, and an inclined resistance block 56 is provided on the resistance rod 53. The inclined resistance block 56 is located at the same end of the rack 55 on the resistance rod 53. A limit strip 57 is slidably connected to the bottom of the resistance rod 53, which limits the sliding position of the resistance rod 53 to ensure that the movement range of the supporting assembly 5 meets the design requirements. The limit strip 57 is fixedly installed on the inner side of the slope 42, and the limit strip 57 is used to limit the sliding position of the resistance rod 53.

[0038] In this embodiment: a round rod 58 is provided on the supporting rod 51, and the round rod 58 is slidably connected to a limiting track 59, and one end of the limiting track 59 is fixedly connected to an inclined track 510, and the inclined track 510 has a certain inclination angle. This design can resist the supporting rod 51 during the blanking process of the metal tube 2, so that the supporting rod 51 slides along a specific direction, which helps to maintain the stability of sliding. The limiting track 59 and the inclined track 510 are both fixedly installed on the inner side of the slope 42. The design of limiting the position of the round rod 58 by the limiting track 59 and the inclined track 510 can ensure that the rolling process of the metal tube 2 is effectively controlled.

[0039] In this embodiment, the transmission assembly 6 includes a gear 61 meshing with the rack 55, the gear 61 is slidably connected with a transmission column 62, and the transmission column 62 is rotatably connected with the limit bar 57. This design enables the transmission column 62 to rotate with the support of the limit bar 57, ensuring the stability and controllability of the transmission. The transmission column 62 is provided with a meshing groove 63, which is meshing with the inner side of the gear 61. The design of the meshing groove 63 allows the gear 61 to rotate while driving the transmission column 62 to rotate together. One side of the wheel 61 is rotatably connected to a control block 64, and a control rod 65 is fixedly connected to the control block 64. This structure can be used to control the movement of the gear 61 to ensure the accuracy and stability of the transmission. A sloped support block 66 is fixedly connected to the control rod 65. The slope of the sloped support block 66 is used to conflict with the slope of the sloped contact block 56. This design can achieve further control of the gear 61 during the process of cutting the metal tube 2 through the contact of the sloped contact block 56 with the slope of the sloped support block 66.

[0040] In this embodiment: a worm 69 for transmitting power is fixedly installed at one end of the transmission column 62, and the worm 69 is meshingly connected with a turbine 610 for receiving power. The turbine 610 is a key component in the transmission system of the worm 69, and the turbine 610 produces corresponding movement according to the rotation of the worm 69.

[0041] In this embodiment: the inclined surface support block 66 is connected to a first control component 67, and the first control component 67 is fixedly installed at the lower inner side of the slope 42. The first control component 67 includes a telescopic rod 671 fixedly connected to the inclined surface support block 66, and the telescopic rod 671 is slidably connected to a pressure oil tank 672. By adjusting the oil pressure in the pressure oil tank 672, the telescopic state of the telescopic rod 671 can be controlled, thereby adjusting the position of the inclined surface support block 66. A sealing gasket 673 is fixedly connected to the telescopic rod 671, and the sealing gasket 673 is slidably connected to the inner wall of the pressure oil tank 672. A limiting round block 674 is fixedly installed on the pressure oil tank 672, and the limiting round block 674 is used to limit the position of the sealing gasket 673. The design of the limiting round block 674 allows the position of the telescopic rod 671 to be restricted to a certain extent after the telescopic rod 671 slides, so that the telescopic rod 671 will not slide back automatically. The pressure oil tank 672 is fixedly connected with an oil pipe 675, and the other end of the oil pipe 675 is fixedly connected with a second control component 68 of the same structure. A force block 681 is fixedly connected to the telescopic rod 671 of the second control component 68, and the force block 681 is used to contact the metal pipe 2. The second control component 68 is fixedly installed above the inner side of the slope 42, and the first control component 67 is connected to the second control component 68 through the oil pipe 675, so that the two control components are connected to each other through the hydraulic system to share the hydraulic pressure.

[0042] In this embodiment: the transfer assembly 7 includes a take-over plate 71 rotatably connected to the inner side of the ramp 42. The design of the take-over plate 71 can be adjusted to achieve the unloading of the metal tube 2 at different heights, angles and positions. The design of the take-over plate 71 allows the metal tube 2 to be effectively received and supported during the unloading process. The length of the rack 55 is such that the take-over plate 71 is rotated 180 degrees after transmission. A pair of take-over grooves 72 for receiving the metal tube 2 are provided on the take-over plate 71. These grooves help stabilize the position of the metal tube 2 and prevent it from rolling or swinging during the transfer process. The take-over plate 71 is fixedly connected to the turbine 610. This connection enables the take-over plate 71 to be driven by the turbine 610 to ensure that the metal tube can move smoothly during the transfer process. A limiting arc plate 73 for preventing the metal tube 2 from falling during the transfer process is installed on one side of the take-over plate 71. The limiting arc plate 73 is fixedly installed on the inner side of the ramp 42, which can effectively prevent the metal tube 2 from falling during the transfer process.

[0043] In this embodiment:

[0044] The steps include:

[0045] S1: placing the treated metal tube 2 that needs to be tempered into a heating device 1 for heating. The heating device 1 can provide the required temperature to make the metal tube 2 reach an appropriate state to prepare for the subsequent tempering treatment. Heating can improve the metal crystal structure and increase the plasticity of the metal, making it easier to perform the tempering treatment;

[0046] S2: The heated metal tube 2 is transported to the quenching equipment 3 for quenching. The quenching equipment 3 can quickly cool the metal tube 2 to make the surface and the inside of the metal tube reach the required hardness, increase the hardness of the metal, and increase the elasticity and tensile resistance of the metal;

[0047] S3: The quenched metal tube 2 is transferred through the unloading device 4. The unloading device 4 can stably transfer the quenched metal tube 2 to the next processing site to ensure the continuity of the whole process. The transfer process can avoid damage to the metal tube 2 during the processing and maintain its shape and quality.

[0048] S4: The metal tube 2 is transferred to the next processing site and subjected to tempering treatment. Tempering can adjust the hardness and strength of the metal to achieve more ideal mechanical properties, while improving fatigue resistance and deformation resistance.

[0049] Working principle: First, put the metal tube 2 into the heating device 1. After the heating of the metal tube 2 is completed, the metal tube 2 will be conveyed to the quenching device 3 through the conveyor of the equipment to quench the metal tube 2. After the quenching of the metal tube 2 is completed, the metal tube 2 will be transferred to the unloading device 4 through the conveyor. After the metal tube 2 enters the base 41, it will roll down through the auxiliary inclined rod 44. During the rolling process, it will conflict with the supporting rod 51, pushing the supporting rod 51 to slide together. During the sliding process of the supporting rod 51, under the sliding restriction of the round rod 58, the limiting track 59 and the inclined track 510, the supporting rod 51 gradually moves toward the limiting tube. 52 slides inside, and when the supporting rod 51 is pushed, it will drive the limiting tube 52 and the resistance rod 53 below the limiting tube 52 to slide together. When the resistance rod 53 slides, it pulls the spring 54 to deform, and drives the rack 55 to slide together. As the sliding continues, the rack 55 is meshed with the gear 61, and the gear 61 is driven to rotate during the continuous sliding of the rack 55. When the gear 61 rotates, it drives the transmission column 62 to rotate together. When the transmission column 62 rotates, it drives the worm 69 to rotate together. When the worm 69 rotates, it drives the turbine 610 to rotate, and the connecting plate 71 rotates along with it.

[0050] As the metal tube 2 rolls, the interference rod 53 drives the rack 55 to slide continuously. When the rack 55 passes the gear 61, it can just drive the connecting plate 71 to rotate 180 degrees, so that the connecting groove 72 with the metal tube 2 can unload the metal tube 2, and at the same time, the connecting groove 72 after unloading is transferred to the working position. As the rack 55 continues to slide, the inclined surface of the inclined surface interference block 56 is in conflict with the inclined surface of the inclined surface receiving block 66, so that the inclined surface receiving block 66 drives the telescopic rod 671 to slide into the pressure oil tank 672. As the inclined surface receiving block 66 drives the control rod 65 to slide, the control block 64 slides together, so that the gear 61 is separated from the position of the rack 55, and the pressure oil in the first control component 67 is squeezed into the second control component 68, and the force block 681 enters the working state.

[0051] At the same time, the supporting rod 51 drives the rack 55 to engage with the gear 61. When the gear 61 rotates to a position where there is no rack 55, it just drives the connecting plate 71 to rotate 180 degrees. At this time, the inclined surface contact block 56 on the contact rod 53 contacts the inclined surface receiving block 66, driving the control block 64 and the gear 61 to slide downward, so that the gear 61 slides to a position where it cannot engage with the rack 55. At this time, the supporting rod 51 just shrinks into a position flush with the auxiliary inclined rod 44, so that the metal pipe 2 can pass. At the same time, after the supporting rod 51 loses the contact with the metal pipe 2, it drives the contact rod 53 and the rack 55 to slide back under the action of the spring 54, so that the problem of the rack 55 and the gear 61 colliding when sliding back can be avoided.

[0052] As the metal tube 2 continues to roll downward, the supporting rod 51 is restricted by the inclined track 510 and retracts into the restricting tube 52. At this time, the metal tube 2 has rolled close to the end of the auxiliary inclined rod 44. At this time, the metal tube 2 has no much inertia. Subsequently, when the supporting rod 51 is retracted to the level of the auxiliary inclined rod 44, the metal tube 2 will escape the restriction of the supporting rod 51, and at the same time, the rack 55 is pulled back to its original position under the action of the spring 54. At this time, the inclined surface contact block 56 and the inclined surface receiving block 66 are no longer in conflict. With the continuous rolling, the metal tube 2 is in conflict with the force block 681, so that the force block 681 drives the telescopic rod 671 to squeeze the pressure oil in the second control assembly 68 into the first control assembly 67, so that the telescopic rod 671 in the first control assembly 67 is lifted up, driving the inclined surface receiving block 66 to slide together, and at the same time driving the control rod 65 to slide together, and at the same time driving the control block 64 to push the gear 61 back to the working position, preparing for the arrival of the next metal tube 2.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
