Description

Technical Field

[0001] This utility model relates to the field of steel structure surface treatment technology, specifically to a surface quenching device for processing steel structural components. Background Technology

[0002] Surface hardening for steel structural parts is mainly used to improve the surface hardness, wear resistance and fatigue resistance of the parts, while maintaining the toughness and plasticity of the core. The parts are heated to the austenitizing temperature and then rapidly quenched to obtain a martensitic structure. The choice of quenching medium will vary depending on the specific design and requirements of the parts. Quenching fluids such as water, oil or salt water can be selected.

[0003] Chinese patent CN220300792U discloses a surface hardening device for processing steel structural parts, including a base plate. A linear module one and a linear module two are fixedly connected to the top of the base plate. The linear module one and the linear module two have the same structure and are symmetrical. The linear module one and the linear module two include a support column, a lead screw and a guide rod.

[0004] Regarding the aforementioned disclosed technology, during quenching, the liquid quenching medium partially boils the instant the heated metal block enters the quenching medium. The boiling medium is prone to splashing, which can cause injury to workers.

[0005] Therefore, a surface hardening device for processing steel structural components is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a surface hardening device for processing steel structural parts in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A surface hardening device for processing steel structural components includes a base. The top surface of the base is provided with a vertical adjustment mechanism, and the movable part of the vertical adjustment mechanism is equipped with a horizontal moving mechanism. The vertical adjustment mechanism and the horizontal moving mechanism are used to move the steel structure. The bottom surface of the movable part of the horizontal moving mechanism is provided with a lifting device, and the surface of the lifting device is movably fitted with a cover plate. A spring is fitted on the surface of the lifting device and above the cover plate. A hardening cylinder for storing hardening medium is placed on the top surface of the base.

[0009] Furthermore, the vertical adjustment mechanism includes two sets of side frames fixed to the top surface of the base, and the top surfaces of the two sets of side frames are rotatably connected to a first threaded rod. A sprocket is fixedly installed at the top end of the first threaded rod, and chains are meshed on the surfaces of the two sets of sprockets. A motor frame is fixedly installed on the surface of one set of side frames, and a first motor is provided on the top surface of the motor frame. The output end of the first motor is fixed to the end of one set of first threaded rods to drive the first threaded rods and sprockets to rotate. Movable frames are threaded onto the surfaces of both sets of first threaded rods.

[0010] Furthermore, the lateral movement mechanism includes guide shells fixed to the ends of the two sets of movable frames. A second motor is provided on the surface of the guide shell, and a second threaded rod is fixedly installed at the output end of the second motor to drive the second threaded rod to rotate. A movable block is threadedly sleeved on the surface of the second threaded rod.

[0011] Furthermore, the lifting device includes two sets of vertical rods fixedly installed on the bottom surface of the movable block. A horizontal frame is fixedly installed at the bottom end of the two sets of vertical rods, and a hook is fixedly installed on the bottom surface of the horizontal frame. A limiting ring is fixedly sleeved on the surface of the vertical rod, and a cover plate is slidably sleeved on the surface of the vertical rod.

[0025] like Figures 1 to 4 As shown, a surface hardening device for processing steel structural components includes a base 1. A vertical adjustment mechanism 2 is provided on the top surface of the base 1, and a horizontal moving mechanism 3 is provided on the movable part of the vertical adjustment mechanism 2. The vertical adjustment mechanism 2 and the horizontal moving mechanism 3 are used to move the steel structure. A lifting device 4 is provided on the bottom surface of the movable part of the horizontal moving mechanism 3, and a cover plate 5 is movably fitted on the surface of the lifting device 4. A spring 6 is fitted on the surface of the lifting device 4 and above the cover plate 5. A hardening cylinder 7 for storing hardening medium is placed on the top surface of the base 1.

[0026] More specifically, the vertical adjustment mechanism 2 and the horizontal moving mechanism 3 are used to move the position of the lifting device 4 so that the steel structure can be lifted by the lifting device 4;

[0027] Then, the steel structure is moved above the quenching cylinder 7 via the vertical adjustment mechanism 2 and the horizontal moving mechanism 3;

[0028] Subsequently, the vertical adjustment mechanism 2 drives the lifting device 4 and the steel structure to move vertically downward, so that the bottom surface of the cover plate 5 and the top surface of the quenching cylinder 7 come into contact. At this time, the steel structure lifted by the bottom end of the lifting device 4 is located inside the quenching cylinder 7 and does not come into contact with the quenching medium inside the quenching cylinder 7.

[0029] Finally, the vertical adjustment mechanism 2 drives the lifting device 4 and the steel structure to continue moving vertically downward, causing the cover plate 5 to move along the surface of the lifting device 4 to compress the spring 6, so that the steel structure is immersed in the quenching medium in the quenching cylinder 7. The cover plate 5 is placed on the top surface of the quenching cylinder 7, thereby preventing the quenching medium from rolling and splashing during the quenching of the steel structure, and improving the safety of the operators.

[0030] The vertical adjustment mechanism 2 includes two sets of side frames 201 fixed to the top surface of the base 1. The top surfaces of the two sets of side frames 201 are rotatably connected to a first threaded rod 202. A sprocket 203 is fixedly installed at the top of the first threaded rod 202. A chain 204 is meshed on the surfaces of the two sets of sprockets 203. A motor frame 205 is fixedly installed on the surface of one set of side frames 201. A first motor 206 is provided on the top surface of the motor frame 205. The output end of the first motor 206 is fixed to the end of one set of first threaded rods 202 to drive the first threaded rod 202 and the sprocket 203 to rotate. A movable frame 207 is threadedly sleeved on the surface of both sets of first threaded rods 202. More specifically, the first motor 206 drives one set of first threaded rods 202 and sprockets 203 to rotate, and under the action of the chain 204, the other set of first threaded rods 202 and sprockets 203 rotate synchronously. Through the synchronous rotation of the two sets of first threaded rods 202, the movable frame 207, the lateral moving mechanism 3 and the lifting device 4 are moved vertically upward.

[0031] The lateral movement mechanism 3 includes guide shells 301 fixed to the ends of the two sets of movable frames 207. A second motor 302 is provided on the surface of the guide shell 301. A second threaded rod 303 is fixedly installed at the output end of the second motor 302 to drive the second threaded rod 303 to rotate. A movable block 304 is threadedly sleeved on the surface of the second threaded rod 303. More specifically, the second motor 302 drives the second threaded rod 303 to rotate, and the movable block 304 is threadedly sleeved with the second threaded rod 303, thereby causing the movable block 304 to move laterally within the guide shell 301, realizing the lateral movement of the lifting device 4 via the movable block 304.

[0032] The lifting device 4 includes two sets of vertical rods 401 fixedly installed on the bottom surface of the movable block 304. A horizontal frame 402 is fixedly installed at the bottom end of each set of vertical rods 401, and a hook 403 is fixedly installed on the bottom surface of the horizontal frame 402. A limiting ring 404 is fixedly sleeved on the surface of the vertical rods 401. A cover plate 5 is slidably sleeved on the surface of the vertical rods 401, and the two ends of a spring 6 sleeved on the surface of the vertical rods 401 are fixedly installed to the end faces of the limiting ring 404 and the cover plate 5, respectively. More specifically, the hooks 403 are used to hang the steel structure. When the vertical adjustment mechanism 2 immerses the steel structure in the quenching medium, the cover plate 5 is in contact with the top surface of the quenching cylinder 7, causing the cover plate 5 to move vertically along the surface of the vertical rods 401, thus compressing the spring 6.

[0033] The quenching cylinder 7 includes a cylinder 701 placed on the top surface of the base 1. A waste discharge pipe 702 is provided on the surface of the cylinder 701. A wire basket 703 is inserted into the inside of the cylinder 701. Two sets of lifting rods 704 are fixedly installed on the top surface of the wire basket 703, allowing the wire basket 703 to be lifted out of the cylinder 701 via the lifting rods 704. More specifically, the wire basket 703 and the lifting rods 704 are inserted into the inside of the cylinder 701, allowing the quenching medium to be stored within the cylinder 701. When a steel structural component enters the cylinder 701 and is immersed in the quenching medium, the steel structural component is quenched. After quenching, the wire basket 703 is removed from the cylinder 701 via the lifting rods 704, allowing the oxide debris in the quenching medium to be cleaned through the wire basket 703.

[0034] During quenching, the cover plate 5 is fitted against the top of the quenching cylinder 7, at which time the spring 6 is compressed. More specifically, by fitting the cover plate 5 against the top surface of the quenching cylinder 7, the quenching medium inside the quenching cylinder 7 is prevented from tumbling and splashing during quenching.

[0035] In summary: The vertical adjustment mechanism 2 and the horizontal movement mechanism 3 move the position of the lifting device 4, allowing the steel structure to be hoisted. Then, the vertical adjustment mechanism 2 and the horizontal movement mechanism 3 move the steel structure to the top of the quenching cylinder 7. Subsequently, the vertical adjustment mechanism 2 drives the lifting device 4 and the steel structure to move vertically downwards, so that the bottom surface of the cover plate 5 contacts the top surface of the quenching cylinder 7. At this time, the steel structure lifted by the bottom end of the lifting device 4 is located inside the quenching cylinder 7 and does not come into contact with the quenching medium inside the quenching cylinder 7. Finally, the vertical adjustment mechanism 2 drives the lifting device 4 and the steel structure to continue moving vertically downwards, so that the cover plate 5 moves along the surface of the lifting device 4 to compress the spring 6, immersing the steel structure in the quenching medium inside the quenching cylinder 7. The cover plate 5 covers the top surface of the quenching cylinder 7, thus preventing the quenching medium from tumbling and splashing during quenching of the steel structure, improving the safety of the operators.
