Description

Technical Field

[0001] This utility model relates to the field of mold steel billet processing technology, specifically a lifting clamp for mold steel billets. Background Technology

[0002] Mold steel billets are raw metal blanks, typically unprocessed metal blocks or billets used to manufacture molds or tool components. Lifting clamps can effectively and safely handle and suspend these heavy metal blanks, improving the efficiency, safety, and precision of the mold steel billet handling process and ensuring smooth production. Depending on the mold's requirements, mold steel billets can be further processed into various molds such as cold stamping dies, hot forging dies, and die casting molds. These molds play a key role in manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances.

[0003] The existing lifting clamps for mold steel castings are typically used to handle heavy metal ring billets (referred to as round billets). The round billets have smooth surfaces and are cylindrical in shape. Traditional lifting clamps (such as flat clamps or chain clamps) cannot provide sufficient friction, causing the round billets to slide or roll during handling, increasing the risk of falling. Furthermore, the clamping range of existing lifting clamps is usually fixed, making it difficult to adapt to round billets of different diameters or lengths. Frequent changes of lifting tools are required, increasing the complexity of operation. Therefore, a lifting clamp for mold steel castings is proposed to solve the above-mentioned problems. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a lifting clamp for casting mold steel billets, including an upper beam, and a hook connected to a lifting device is provided on the upper beam. Both ends of the upper beam are provided with pins, and telescopic members are provided on the pins. The end of the telescopic member away from the upper beam is provided with a clamping part for fixing the round billet, and a connecting member is provided between the two telescopic members.

[0005] Furthermore, the telescopic component includes an outer pull rod and an inner pull rod, and the outer pull rod and the inner pull rod are rotatably connected to the pin shaft. The ends of the outer pull rod and the inner pull rod away from the pin shaft are rotatably connected to the inner clamp and the outer clamp through a rotating shaft. The outer clamp is provided with a connecting shaft that passes through the inner clamp and extends to the other side.

[0006] Furthermore, the clamping part includes mounting blocks, one end of the inner clamp and the outer clamp are fixedly mounted with mounting blocks, and the opposite side surfaces of the two mounting blocks are provided with receiving grooves, the receiving grooves are provided with clamp teeth, and the surface of the clamp teeth is provided with a number of anti-slip grooves.

[0007] Furthermore, the connector includes a frame disposed between two external clamps, and a mounting plate is provided on the frame. The end of the connecting shaft away from the external clamps is fixedly mounted on the surface of the mounting plate, and a partition is provided at the bottom of the frame.

[0008] Furthermore, it includes a limiting component disposed between the upper beam and the connecting member. The limiting component includes a connecting arm, which is rotatably connected to one side surface of the upper beam. A swing arm is rotatably connected to one end of the connecting arm away from the upper beam, and the other end of the swing arm is rotatably connected to the frame.

[0009] Furthermore, an opening / closing device is provided on the surface of the upper beam near the connector, and a connecting seat is provided on the frame, with a limiting groove adapted to the opening / closing device on the connecting seat.

[0010] The beneficial effects of this utility model are as follows: By setting up a telescopic component, this utility model links the outer pull rod, inner pull rod, inner clamp, and outer clamp together, automatically tightening the clamping force during lifting to ensure uniform force on the round blank and prevent slippage or rolling. It also has a clamping part with anti-slip grooves on the surface of the clamp teeth to significantly increase the coefficient of friction, and a limit component to prevent damage to the clamp or round blank due to overload. Therefore, it achieves a comprehensive upgrade in the stability, adaptability, safety, and economy of the clamp, providing an efficient and reliable handling solution for the mold steel casting blank processing industry.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] In the embodiments, by Figure 1-2 A lifting clamp for casting mold steel billets is provided, comprising an upper beam 1, on which a hook 2 connected to a lifting device is provided. Pins 3 are provided at both ends of the upper beam 1, and telescopic members 4 are provided on the pins 3. A clamping part 5 for fixing the billet is provided at the end of the telescopic member 4 away from the upper beam 1, and a connecting member 6 is provided between the two telescopic members 4. The lifting device applies a vertical lifting force to the upper beam 1 through the hook 2. The upper beam 1, as the main load-bearing structure, is made of high-strength alloy steel. When the clamp jaws contact the surface of the billet, the reaction force of the billet causes the inner and outer clamps to finely adjust their angles around the pivot 43 until the billet is wrapped, until the clamping part 5 adaptively fits the curved surface of the billet, ensuring the contact area, thereby achieving the clamping and fixing of the billet, which is then transported by the lifting device.

[0018] Reference Figure 1-2 The telescopic component 4 includes an outer pull rod 41 and an inner pull rod 42. The outer pull rod 41 and the inner pull rod 42 are rotatably connected to the pin 3. The ends of the outer pull rod 41 and the inner pull rod 42 away from the pin 3 are rotatably connected to the inner clamp 44 and the outer clamp 45 through the rotating shaft 43. The outer clamp 45 is provided with a connecting shaft 46 that passes through the inner clamp 44 and extends to the other side.

[0019] Reference Figure 1-2 The clamping part 5 includes a mounting block 51. The inner clamp 44 and the outer clamp 45 are both fixedly mounted with the mounting block 51. The two mounting blocks 51 are provided with a receiving groove on the opposite side surface. The receiving groove is provided with clamp teeth 52. The surface of the clamp teeth 52 is provided with a plurality of anti-slip grooves 53.

[0020] With the above structural setup, the inner clamp 44 and the outer clamp 45 are fixed to the mounting block 51 by high-precision machining to ensure the consistency of the mounting reference surface of the clamp teeth 52. The clamp teeth 52 adopt a dovetail groove structure to be embedded in the receiving groove of the mounting block 51 and fastened by a single-sided bolt to achieve quick replacement and adapt to different working conditions.

[0021] Reference Figure 1-2 The connector 6 includes a frame 61 disposed between two external clamps 45, and a mounting plate 62 is disposed on the frame 61. The end of the connecting shaft 46 away from the external clamps 45 is fixedly mounted on the surface of the mounting plate 62. A partition 63 is disposed at the bottom of the frame 61.

[0022] With the above structural design, the partition 63 effectively separates the round blank from the frame 61, preventing the round blank from being damaged by friction during transportation.

[0023] Reference Figure 1-2 The component includes a limiting assembly 7 disposed between the upper beam 1 and the connecting piece 6. The limiting assembly 7 includes a connecting arm 71, which is rotatably connected to one side surface of the upper beam 1. The end of the connecting arm 71 away from the upper beam 1 is rotatably connected to a swing arm 72, and the other end of the swing arm 72 is rotatably connected to the frame 61.

[0024] Through the above structural arrangement, the connection between the connecting arm 71 and the swing arm 72 effectively limits the range of motion of the telescopic component 4.

[0025] Reference Figure 1-2 The upper beam 1 is provided with an opening and closing device 8 on the side surface near the connector 6, and the frame 61 is provided with a connecting seat 9, and the connecting seat 9 is provided with a limiting groove 10 that is adapted to the opening and closing device 8.

[0026] With the above structural design, the opener / closer 8 adopts existing technology and can be purchased directly from the market. When the locking tongue of the opener / closer 8 is inserted into the limiting groove 10, the locking tongue is tightly fitted with the side wall of the limiting groove 10 to achieve self-locking.
