Description

Technical Field

[0001] The invention belongs to the technical field of metal heat treatment, and in particular relates to a metal heat treatment device. Background Art

[0002] After the steel structure is welded, there is residual stress in the structure. During the subsequent use, the residual welding stress will be slowly released over time, causing the structure to deform accordingly. For structures with high machining accuracy requirements, stress relief annealing or stress relief tempering must be performed before machining. During the heat treatment process, when taking the metal out of the inner wall layer, the traditional way of taking it out is to use a hook to remove the protective cover of the heat treatment box, and then use the hook to lift the rack containing the steel structure components to take out the metal parts. However, due to the high temperature inside the box, after the hook is placed in the box, the temperature inside the box, the hot oil, and the thermal conductivity of the metal when connecting the hook to the rack can easily cause burns, posing a safety hazard. For example, the patent with announcement number CN215481072U discloses a metal heat treatment device, including an inner wall layer, a first temperature measurement module, a heating module and a motor. A heat insulation layer is arranged between the inner wall layer and the box body, and a quenching port is opened on the top of the box body.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] See also Figures 1 to 6 The metal heat treatment device of the present invention comprises a box body 1 and a protective cover 2 abutting against the surface of the discharge port of the box body 1. A support column 3 and a fixing plate 4 fixedly arranged on the surface of the support column 3 are fixedly arranged at the bottom of the box body 1. In order to facilitate the heat treatment process, the metal can be easily taken out of the box body 1 or put into the box body 1.

[0029] A locking assembly 5 for assisting lifting is provided on the upper surface of the protective cover 2, and a loading assembly 6 fixedly connected thereto is provided below the protective cover 2; the locking assembly comprises a collar 51, a spring A52, a sleeve rod 53 and a connecting rod 54; the collar 51 is vertically arranged on the top surface of the protective cover 2, and the collar 51 is fixedly connected to the upper surface of the protective cover 2; a notch is provided at the top of the collar 51, a slot is provided at the end of the notch of the collar 51, a through slot is provided at the end of the sleeve rod 53, the sleeve rod 53 is relatively arranged and respectively inserted into the slot at the end of the collar 51, the connecting rod 54 passes through the through slot of the sleeve rod 53 and is fixedly connected to the inner wall of the slot of the collar 51, the connecting rod 54 abuts against the side wall of the through slot, and a spring A52 is provided between the connecting rod 54 and the side wall of the through slot near one end of the notch of the collar 51; when the hook acts on the protective cover 2, the interval between the opposite ends of the sleeve rod 53 forms a channel for the hook to be hung into the collar 51.

[0030] Since the locking assembly 5 is arranged on the upper surface of the protective cover 2 and is not in the box 1, its temperature is lower than the temperature in the box 1, and the operation of placing the hook into the box 1 is avoided. The hook is placed between the sleeve rods 53 and pressed downward. The sleeve rod 53 is forced to drive the spring A52 to compress and insert into the ring 51 until the hook enters the ring 51. The spring A52 is forced to rebound and push the sleeve rod 53 to reset. At this time, the gap between the sleeve rods 53 is smaller than the cross-sectional width of the hook, and the connection with the hook is realized. While facilitating people to perform lifting operations, it can avoid contact between the human body and the sleeve rod 53, reducing the risk of scalding and safety hazards. After the sleeve rod 53 is reset, the elastic force generated by the spring A52 causes the sleeve rod 53 to approach each other to reduce the gap distance. After the hook is inserted into the ring 51, the sleeve rod 53 is in the hook. At this time, the hook is dragged upward, and the hook can drag the protective cover 2 upward as a whole through the sleeve rod 53, and the dragging force will not affect the thrust generated by the spring A52, ensuring that people can perform stable lifting operations.

[0031] Specifically, the slots of the sleeve rod 53 and the collar 51 are both in arc shape, and the plug-in end surface of the sleeve rod 53 abuts against the inner wall of the slot of the collar 51. The through slot of the sleeve rod 53 is in arc shape, and the surface of the connecting rod 54 abuts against the inner wall of the through slot of the sleeve rod 53. When the sleeve rod 53 is squeezed, the sleeve rod 53 is received into the collar 51 along the slot, thereby expanding the distance between the sleeve rods 53 and facilitating people to insert the hook into the collar 51. The sleeve rod 53 in motion is limited by the collar 51 and the connecting rod 54, ensuring that the sleeve rod 53 can only move in an arc shape along the collar 51.

[0032] Specifically, the opposite ends of the sleeve rod 53 are designed to be inclined inwards to form an inverted trapezoidal structure. This design can provide a guiding force for the hook to be pressed down, so that the hook contacts the inclined surface by pressing down and squeezes the sleeve rod 53, making it easier for people to insert the hook into the ring 51.

[0033] Furthermore, it also includes mounting seats 533 respectively and symmetrically welded to adjacent ends of the sleeve rods 53, a shift plate 532 is hinged inside the mounting seat 533 through a rotating shaft, a spring B531 is fixedly provided on the surface of the shift plate 532 located on one side of the mounting seat 533, and the end of the spring B531 away from the shift plate 532 is inserted into a groove opened on the surface of the sleeve rod 53, and is fixedly connected to the inner wall of the groove.

[0034] When the hook pushes the sleeve rods 53 away from each other by pressing down, the paddle plate 532 can be driven away and the paddle plate 532 can be pressed to make the paddle plate 532 swing downward along the mounting seat 533 until the hook is inserted into the collar 51. At this time, while the sleeve rods 53 are being reset, the paddle plate 532 can be reset to further reduce the gap between the sleeve rods 53, making it easier for people to lift with the hook. Before the hook enters the sleeve rod 53, the paddle plates 532 are in a state of abutting each other, which is the default state. Therefore, after being reset, they are affected by the elastic force and return to the initial state. Please refer to the attached figure. Figure 4 One side of the paddle plate 532 contacts the surface of the sleeve rod 53. When the paddle plate 532 contacts the sleeve rod 53 after being reset, the paddle plate 532 cannot continue to flip upward when the hook is lifted.

[0035] Specifically, the adjacent ends of the two plates 532 are provided with equally spaced slots, and the slots on the surfaces of the two plates 532 are staggered. When the sleeve rod 53 is reset, the plates 532 are pushed to engage with each other through the slots, forming a closed loop structure between the sleeve ring 51 and the sleeve rod 53, further preventing the hook from falling off, ensuring stability during lifting operations, and reducing safety hazards.

[0036] See also Figures 2 to 9 The material loading assembly 6 includes a sleeve A61, a sleeve B63 and a sleeve plate 64. The sleeve A61 is sleeved on the sleeve B63. The sleeve plate 64 is arranged below the protective cover 2. A mounting plate is screwed on the side surface of the sleeve plate 64 facing the protective cover 2. The protective cover 2 and the mounting plate are connected through the sleeve B63 and the sleeve A61 arranged in a ring shape.

[0037] The sleeve connection portion between the sleeve A61 and the sleeve B63 is provided with a chute along its axial direction, and the sleeve B63 is fixedly provided with a limit rod 65 slidably connected to the chute corresponding to the chute, and the chute is provided with limit grooves for the limit rod to engage at intervals.

[0038] In an optional embodiment: a loading plate 66 slidably connected to the sleeve plate 64 is provided inside the sleeve plate 64, a sliding groove is vertically provided on the side wall of the sleeve plate 64, and a slider 661 slidably connected to the sliding groove is welded to the edge of the loading plate 66; an adjustment part for adjusting the lifting of the loading plate 66 is provided at the bottom of the sleeve plate 64; a storage platform 662 is fixedly connected to the upper surface of the loading plate 66.

[0039] In this embodiment: the sleeve B63 is moved to a suitable position along the sleeve A61 by pulling the sleeve plate 64, and the sleeve B63 is pushed to rotate in the same direction by the sleeve plate 64, so that the sleeve B63 drives the limiting rod 65 to be inserted into the limiting groove at the corresponding position to achieve fixation, so that people can adjust the placement space according to the specifications of the quenched metal.

[0040] It should be noted that the thread force between the mounting plate and the sleeve plate 64 is greater than the force used to move the sleeve B63 when the sleeve plate 64 is rotated. This design can effectively avoid erroneous operation of thread disassembly between the sleeve plate 64 and the mounting plate when the sleeve plate 64 is rotated, thereby ensuring the stability between the sleeve plate 64 and the mounting plate.

[0041] It should be noted that: when placed on the surface of the storage table 662, the loading plate 66 slides downward due to the influence of gravity, causing the bottom of the metal to enter the sleeve plate 64, thereby limiting the metal and ensuring the stability of the metal after it is placed. The loading plate 66 is pushed upward along the sleeve plate 64 through the slider 661 until the storage table 662 moves out of the sleeve plate 64, thereby leaving a gap between the sleeve plate 64 and the metal, making it easier for people to remove the metal.

[0042] In an optional embodiment: the adjusting member includes a card plate 671, an insert plate 67 and a protrusion 672, a sealing groove for installing the card plate 671 is opened on the bottom side wall of the sleeve plate 64, the insert plate 67 is fixedly connected to the card plate 671 and placed in the sleeve plate 64, the protrusion 672 is fixedly set on the upper surface of the sleeve plate 64, the top of the protrusion 672 is in contact with the lower surface of the carrier plate 66, and the contact surfaces of the protrusion 672 and the carrier plate 66 are both inclined.

[0043] In this embodiment: the insert plate 67 is inserted into the sleeve plate 64, and the insert plate 67 is pushed to completely enter the sleeve plate 64. At the same time, the insert plate 67 can push the loading plate 66 to move upward through the protrusion 672. Combined with the above, a gap is left between the sleeve plate 64 and the metal, which is convenient for people to remove the metal.

[0044] In an optional embodiment: a clamping rod B69 is protruding from the outer wall of the sleeve plate 64, a clamping rod A68 is provided at one end of the clamping plate 671, and the clamping rod B69 is provided with a clamping groove for clamping the clamping rod A68. When the clamping plate 671 is installed in the sealing groove, the clamping rod A68 is clamped in the clamping groove.

[0045] In this embodiment: In combination with the above, after the plug plate 67 is completely inserted into the sleeve plate 64, the clamp rod A68 is inserted into the clamp rod B69 to form a columnar structure. People can achieve connection by arranging a ring outside the clamp rod A68 and the clamp rod B69 to prevent the loading plate 66 from being squeezed by the gravity of the protrusion 672 to cause the plug plate 67 to move, thereby ensuring the stability of the plug plate 67. The surfaces of the clamp rod A68 and the clamp rod B69 can be provided with threads. When the clamp rod A68 is inserted into the cavity opened on the surface of the clamp rod B69 to form a columnar structure with the clamp rod B69, the threads overlap, so that the connection is made through the external nut, further ensuring firmness.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
