Description

Technical Field

[0001] This utility model relates to the field of mold steel heat treatment technology, and in particular to a mold surface heat treatment quenching lifting tool. Background Technology

[0002] Currently, in the process of using quenching hangers, the spacing between the connecting plates is fixed. When the mold steel is wide, the rotation radius of the mold steel is large, which can easily cause interference between the mold steels and affect their use.

[0003] Existing technology CN219990934U discloses a furnace loading and unloading hanger for heat treatment of mold steel, including a support plate and a hanger fixedly connected to the support plate. The support plate has four annularly distributed movable slots. Movable seats are slidably installed in the movable slots. Clamping seats are rotatably installed at the bottom of the movable seats. Bidirectional screws are rotatably installed at the bottom of the clamping seats. Two symmetrical clamping plates are threaded onto the bidirectional screws. A transverse screw is rotatably installed inside the movable slots. The movable seats are threaded onto the transverse screws. A motor for driving the clamping seats to rotate is fixedly installed on the top of the movable seats. Through the arrangement of the movable slots, movable seats, and transverse screws, the transverse screws can be rotated using a second knob, causing the transverse screws to move the movable seats within the movable slots, which in turn causes the movable seats to move the clamping seats. This allows the spacing of the clamping seats to be adjusted according to the width of the mold steel, reducing interference between mold steel components.

[0004] However, when using the above method, the quenching lifting tool needs to be suspended from the crane by the hook. During the suspension process, the hook is prone to instability, which may lead to safety hazards. Utility Model Content

[0005] The purpose of this utility model is to provide a mold surface heat treatment quenching lifting tool, which can improve the stability of the hook suspension and reduce safety hazards when the lifting frame is suspended on the crane by the hook during the use of the quenching lifting tool.

[0006] To achieve the above objectives, this utility model provides a mold surface heat treatment quenching lifting fixture, including a lifting fixture body, a lifting frame and a lifting hook. The lifting frame is fixedly connected to the lifting fixture body and located on one side of the lifting fixture body. The lifting hook is fixedly connected to the lifting frame and located on one side of the lifting frame. It also includes a stabilizing device.

[0007] The stabilizing device includes a hook, a rotating assembly, a resistance assembly, and a locking assembly. The hook is rotatably connected to the hook and is located on one side of the hook. The rotating assembly is disposed on the hook, and the hook is connected to the rotating assembly. The resistance assembly is disposed on the hook, and the locking assembly is disposed on the hanger and the hook, respectively.

[0008] The rotating assembly includes a bushing and a rotating shaft. The bushing is fixedly connected to the hook and is located on one side of the hook. The rotating shaft is rotatably connected to the bushing and fixedly connected to the hook.

[0009] The resistance component includes a resistance block and raised particles. The resistance block is fixedly connected to the hook and is located on one side of the hook. The raised particles are disposed on the side of the resistance block near the hook.

[0010] The locking assembly includes a positioning seat and a snap-fit ​​component. The positioning seat is fixedly connected to the hanger and the hook. The snap-fit ​​component is respectively disposed on the positioning seat and the hook.

[0011] The snap-fit ​​component includes an adsorption block and a snap-fit ​​block. The adsorption block is fixedly connected to the positioning seat and is located on one side of the positioning seat. The snap-fit ​​block is fixedly connected to the hook and is detachably connected to the adsorption block.

[0012] This utility model discloses a mold surface heat treatment quenching lifting fixture, comprising a lifting fixture body, a lifting frame, a lifting hook, and a stabilizing device. The stabilizing device includes a hook, a rotating component, a resistance component, and a locking component. During the use of the quenching lifting fixture, after the lifting frame is suspended onto a crane via the hook, the rotating component rotates the hook, causing the hook to drive the resistance component to rotate towards the lifting frame. This causes the resistance component on the hook to abut against the crane, thereby clamping and fixing the crane in conjunction with the hook. This increases the resistance generated between the hook and the crane, thereby improving the stability of the hook suspension and reducing safety hazards. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The first embodiment of this application is:

[0021] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the mold surface heat treatment quenching lifting fixture. Figure 2 This is a schematic diagram of the stabilizing device. Figure 3 This is a front view of the hook. Figure 4 This is a schematic diagram of the snap-fit ​​component structure. This utility model provides a mold surface heat treatment quenching lifting tool: including a lifting tool body 101, a lifting frame 102, a lifting hook 103, and a stabilizing device. The stabilizing device includes a hook 104, a rotating assembly, a resistance assembly, and a locking assembly. The rotating assembly includes a bushing 105 and a rotating shaft 106. The resistance assembly includes a resistance block 107 and protruding particles 108. The locking assembly includes a positioning seat 109 and a snap-fit ​​component. The snap-fit ​​component includes an adsorption block 110 and a snap-fit ​​block 111. The aforementioned solution addresses the issue that when using a quenching lifting tool, the lifting frame 102 needs to be suspended from the crane via the hook 103. During this process, the hook 103 is prone to instability, leading to safety hazards. The solution aims to improve the stability of the hook 103 during the suspension of the lifting frame 102 from the crane, reducing safety risks. It also helps maintain stability after the hook 104 rotates.

[0022] In this specific embodiment, the hanger 102 is fixedly connected to the lifting device body 101 and located on one side of the lifting device body 101. The hook 103 is fixedly connected to the hanger 102 and located on one side of the hanger 102. The lifting device body 101 is used to clamp and fix the mold. The hanger 102 is welded to the upper surface of the lifting device body 101. The hook 103 is fixed at the center of the upper surface of the hanger 102, so that the hook 103 can be suspended on the crane, thereby allowing the lifting device body 101 to clamp and suspend the mold.

[0023] The hook 104 is rotatably connected to the hook 103 and located on one side of the hook 103. A rotating assembly is disposed on the hook 103, and the hook 104 is connected to the rotating assembly. A resistance assembly is disposed on the hook 104. Locking assemblies are respectively disposed on the hanger 102 and the hook 103. The rotating assembly is located on the right side of the hook 103, and the hook 104 is connected to the rotating assembly. The hook 104 has a certain arc surface and can rotate on the hook 103 via the rotating assembly. The resistance assembly is disposed on the outer surface of the hook 104. After the hook 103 is suspended on the crane, rotating the hook 104 towards the hanger 102 allows the resistance assembly on the hook 104 to cooperate with the hook 103 to lock and fix the crane, improving the stability of the crane. The resistance generated between hook 103 and the crane makes the suspension of hook 103 more stable. The upper surface of the hanger 102 is provided with the locking assembly. After the hook 104 is rotated, the hook 104 is kept stable by the locking assembly, thereby locking and fixing the crane with the hook 103. During the use of the quenching lifting tool, after the hanger 102 is suspended from the crane by the hook 103, the hook 104 is rotated by the rotating assembly, so that the hook 104 drives the resistance assembly to rotate in the direction of the hanger 102, so that the resistance assembly on the hook 104 abuts against the crane, thereby making the resistance assembly cooperate with the hook 103 to clamp and fix the crane, increasing the resistance generated between hook 103 and crane, thereby improving the suspension stability of hook 103 and reducing safety hazards.

[0024] Secondly, the bushing 105 is fixedly connected to the hook 103 and located on one side of the hook 103; the rotating shaft 106 is rotatably connected to the bushing 105 and fixedly connected to the hook 104. There are two bushings 105, which are fixed to the front and rear sides of the end of the hook 103 respectively. The front and rear ends of the rotating shaft 106 are inserted into the two bushings 105 respectively. The circular cross-sectional dimension of the rotating shaft 106 is adapted to the internal circular cross-sectional dimension of the bushing 105, so that the rotating shaft 106 can rotate within the bushing 105. The circumferential surface of the rotating shaft 106 is welded to the hook 104, so that when the rotating shaft 106 rotates within the bushing 105, it can drive the hook 104 to move closer to or away from the hanger 102.

[0025] Meanwhile, the resistance block 107 is fixedly connected to the hook 104 and located on one side of the hook 104; the protruding particle 108 is disposed on the side of the resistance block 107 near the hook 103; the resistance block 107 is sleeved and fixed on the outer surface of the hook 104; the resistance block 107 is made of soft rubber material; the resistance block 107 has a large volume; and the resistance block 107 has an arc surface that matches the hook 103, so that the resistance block 107 and the hook 103 can form a circle, allowing the hook 103 to be suspended. Then, the hook 104 is rotated, which drives the resistance block 107 to move towards the crane, so that the resistance block 107 comes into contact with the crane, thereby increasing the resistance generated between the hook 103 and the crane and improving the suspension stability of the hook 103. Furthermore, the left side of the resistance block 107 is provided with the protruding particles 108. The arrangement of the protruding particles 108 can increase the contact area between the resistance block 107 and the crane, thereby increasing the resistance generated between them, making the suspension of the hook 103 in conjunction with the resistance block 107 more stable.

[0026] Additionally, the positioning seat 109 is fixedly connected to the hanger 102 and to the hook 103; the adsorption block 110 is fixedly connected to the positioning seat 109 and located on one side of the positioning seat 109; the snap-fit ​​block 111 is fixedly connected to the hook 104 and detachably connected to the adsorption block 110; the positioning seat 109 is fixed to the upper surface of the hanger 102, and the positioning seat 109 wraps around the bottom of the hook 103; a rectangular groove is provided on the right side of the positioning seat 109; the adsorption blocks 110 are fixed on both the front and rear sides of the rectangular groove of the positioning column; the adsorption blocks 110 are made of neodymium iron boron magnets; the hook... The left end of 104 is fixed with the snap-fit ​​block 111, which is made of metal. The size of the snap-fit ​​block 111 is slightly smaller than the size of the rectangular groove. The snap-fit ​​block 111 can be placed between the two adsorption blocks 110, so that the front and rear sides of the snap-fit ​​block 111 abut against the sides of the two adsorption blocks 110 that are close to each other. Under the action of the magnetic field, the adsorption blocks 110 and the snap-fit ​​block 111 generate mutual attraction, so that the hook 104 can maintain a stable state after rotation. This allows the resistance block 107 and the hook 103 to cooperate with each other to suspend the crane, improving the suspension stability of the hook 103.

[0027] When using a mold surface heat treatment quenching hanger according to this embodiment, during the use of the quenching hanger, after the hanger 102 is suspended on the crane by the hook 103, the rotating shaft 106 rotates within the bushing 105, causing the rotating shaft 106 to drive the hook 104 to rotate. This causes the hook 104 to drive the resistance block 107 to rotate towards the hanger 102. After the resistance block 107 locks the crane with the hook 103 through the protruding particles 108, the left end of the hook 104 is engaged between the two adsorption blocks 110 by the snap-fit ​​block 111, keeping the hook 104 in a stable state. This increases the resistance between the hook 103 and the crane, thereby improving the suspension stability of the hook 103 and reducing safety hazards.
