Description

Technical Field

[0001] This invention relates to the field of mold steel processing equipment technology, specifically to a lifting clamp for mold steel casting billets. Background Technology

[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Molds are the main processing tools for manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances. After the mold plate steel billet is cast, it still needs to undergo rough machining, surface heat treatment, and other processes. To ensure the smooth progress of these processes, the mold plate steel billet needs to be clamped, hoisted, and turned over. Current technology usually uses lifting clamps to clamp and fix the mold plate steel billet, and then uses iron chains to connect the lifting clamps to a crane, and uses the control crane to achieve the purpose of hoisting the mold plate steel billet.

[0003] Lifting clamps can be classified into vertical lifting clamps, horizontal lifting clamps, and tilting lifting clamps, depending on their usage. As the name suggests, horizontal lifting clamps are suitable for horizontal lifting of steel plates, while vertical lifting clamps are suitable for vertical lifting of steel plates. Due to the different directions of force, horizontal and vertical lifting clamps are used in different ways and cannot be used interchangeably. This means that when changing the lifting method, the clamps need to be replaced, which is not only inconvenient and time-consuming, but also reduces the practicality of the lifting clamps.

[0004] To address this, a lifting clamp for mold steel casting billets is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting clamp for mold steel casting billets to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting clamp for mold steel casting billets, including a clamping base;

[0007] The card holder has a U-shaped structure design. A groove is provided on the outer surface of the front end of the card holder. A first caliper and a second caliper are movably connected inside the groove. The first caliper and the groove are rotatably connected by an adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes a bearing ring, and the front ends of the first caliper and the second caliper are fixedly connected to a connecting ring. The outer surface of the first caliper and the second caliper away from the connecting ring is designed with an arc shape, and the arc surface is provided with a plurality of first tooth grooves. The upper and lower outer surfaces of the first caliper and the second caliper are rotatably connected to the grooves through the bearing ring. A locking block is fixedly connected to one end of the outer surface of the first caliper, and the outer surface of the locking block is provided with a second tooth groove.

[0009] Because of the different directions of force, horizontal and vertical lifting clamps are used differently and cannot be used interchangeably. Changing the lifting method necessitates changing the clamps, which is inconvenient, time-consuming, and labor-intensive, reducing the practicality of the clamps. This invention addresses this by incorporating an adjustment mechanism. When vertically lifting a molded plate-shaped steel billet, the clamp opening faces downwards, engaging the billet between the first and second clamps. A steel cable is then connected to two connecting rings, and a crane lifts the cable, simultaneously lifting the first and second clamps. Under gravity, the clamps exert a compressive force on the billet, locking it tightly. The first toothed groove further increases friction between the clamps and the billet, achieving vertical lifting. When horizontally lifting the billet, the clamp opening is adjusted... Turn left and then counterclockwise to rotate the first clamp, causing the clamp block to rotate to a position parallel to the front end of the clamp seat. At this time, the first clamp and the clamp seat are on the same vertical line. The mold plate steel casting is clamped between the second clamp and the clamp block. Then, the steel cable is connected to the connecting ring, and the steel cable is lifted by a crane. The second clamp is lifted accordingly. Under the influence of gravity, the second clamp generates a squeezing force on the mold plate steel casting, thereby clamping the clamp and the plate steel casting tightly together. By setting the first and second toothed grooves to squeeze the plate steel casting, the friction between the clamp and the plate steel casting is increased, thereby achieving the purpose of horizontal lifting of the plate steel casting. This invention, by setting an adjustment mechanism, allows the clamp to achieve both horizontal and vertical lifting methods by rotating the first clamp, improving the practicality of the clamp. When changing the lifting method, there is no need to replace the clamp, improving the convenience of using the clamp.

[0010] Preferably, a fixing ring is fixedly connected to one side of the outer surface of the connecting ring connected to the first caliper, and a screw hole is opened inside the caliper at the rear end of the bearing ring.

[0011] During operation, this invention, by setting a fixing ring and screw holes, allows for horizontal lifting of plate-shaped steel billets. When the first clamp is rotated counterclockwise to align with the front of the clamp seat, the fixing ring rotates accordingly and aligns with the screw hole. Bolts are then passed through the screw hole and the fixing ring in sequence to connect the two, thereby fixing the first clamp and the clamp block. This prevents the first clamp from rotating under force, which could cause the plate-shaped steel billet to detach from the clamp.

[0012] Preferably, two connecting cylinders are fixedly connected to the upper outer surface of the caliper at the position above the bearing ring, and torsion springs are fixedly connected between the first caliper, the second caliper and the connecting cylinders.

[0013] During operation, this invention incorporates a torsion spring. When clamping a plate-shaped steel billet, the torsion of the spring causes the first and second clamps to exert a compressive force on the billet, resulting in a tighter fit between the clamps and the billet. Simultaneously, the torsion spring's torque also limits the movement of the first and second clamps, preventing them from rotating during clamping and facilitating operation.

[0014] Preferably, a connecting groove is formed on the upper outer surface of the first caliper at the position inside the bearing ring. A connecting block is fitted inside the connecting groove. The upper outer surface of the connecting block is fixedly connected to a torsion spring. A through hole is formed on the upper outer surface of the caliper near the torsion spring. A slider is fixedly connected to the upper end of the torsion spring through the through hole. The outer surface of the slider is slidably connected to the connecting cylinder. A first connecting rod is rotatably connected to the center position of the upper outer surface of the slider via a rotating shaft. A threaded sleeve is fixedly connected to the upper outer surface of the first connecting rod. A threaded ring is fixedly connected to the upper outer surface of the connecting cylinder at the position outside the first connecting rod. The threaded ring and the threaded sleeve are threadedly connected.

[0015] During operation, this invention features a connecting groove that fits snugly against a connecting block. When the first caliper rotates, it drives the connecting block to rotate, causing the torsion spring to undergo torsional deformation and generating a restoring force in the opposite direction on the first caliper. This ensures that the first caliper fits tightly against the plate-shaped steel billet. When the first caliper needs to be rotated, the threaded sleeve is rotated to separate it from the threaded ring. Then, the threaded sleeve is moved upward, causing the first connecting rod to move upward. The slider moves upward with the first connecting rod, thereby causing the torsion spring and the connecting block to move upward, separating the connecting block from the connecting groove. This releases the torsional force exerted by the torsion spring on the first caliper, allowing the first caliper to rotate smoothly. The threaded connection between the threaded sleeve and the threaded ring fixes the first connecting rod, thereby limiting the vertical movement of the connecting block and preventing it from detaching from the connecting groove under stress.

[0016] Preferably, the connecting block is slidably connected to the connecting groove and the through hole in a regular hexagonal structure, and the slider is also slidably connected to the connecting cylinder in a regular hexagonal structure.

[0017] During operation, this invention prevents relative rotation between the connecting block and the connecting groove, and between the slider and the connecting cylinder, when the first caliper rotates. This prevents the torsion spring from generating torsional deformation and thus failing to provide a restoring force to the first caliper. Furthermore, by sliding the through hole and the connecting block together in a hexagonal structure, the invention prevents the connecting block from rotating after disengaging from the connecting groove. This prevents the connecting block and the connecting groove from becoming misaligned, which would prevent the connecting block from smoothly entering the connecting groove after the first caliper resets.

[0018] Preferably, a second connecting rod is rotatably connected between the slider and the connecting block, and the second connecting rod is rotatably connected to the connecting block via a rotating shaft.

[0019] During operation, the present invention connects the slider and the connecting block by setting a second connecting rod, which prevents the connecting block from being compressed by the torsion spring due to force, thereby preventing it from detaching from the connecting groove.

[0020] Preferably, the slider is made of silicon steel, and the top of the inner surface of the connecting cylinder is provided with a magnetic material.

[0021] During operation, this invention uses a slider made of silicon steel and a magnetic material on the top of the inner surface of the connecting cylinder. The slider and the magnetic material attract each other to fix the slider, thereby fixing the connecting block and the first connecting rod and preventing the first connecting rod from sliding up and down under force, which facilitates operation by the staff.

[0022] Preferably, the lower outer surface of the first caliper is provided with an arc-shaped groove located inside the bearing ring, and a protruding rod is fixedly connected to the bottom end of the inner surface of the groove near the arc-shaped groove, and the protruding rod is slidably connected to the arc-shaped groove.

[0023] During operation, this invention limits the first clamp by setting a convex rod and an arc-shaped groove to slide together. When the first clamp rotates counterclockwise, the arc-shaped groove rotates accordingly, and the convex rod and the arc-shaped groove slide relative to each other. When the arc-shaped groove rotates to the end and engages with the convex rod, the fixing ring and the screw hole are aligned, which facilitates the fixing of the two and enables the clamp to perform horizontal lifting. When the first clamp is rotated clockwise to reset, the arc-shaped groove rotates to the other end and engages with the convex rod. At this time, the connecting block and the connecting groove are aligned, which facilitates the smooth entry of the connecting block into the connecting groove and connects the first clamp to the torsion spring.

[0024] Preferably, both the first caliper and the second caliper are made of high manganese steel, which can improve their wear resistance.

[0025] When in operation, high manganese steel has the advantage of good wear resistance. By making the first and second calipers from high manganese steel, the damage caused by friction is reduced and the service life of the two is improved.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This invention improves the practicality of the lifting clamp by setting an adjustment mechanism and rotating the first clamp, enabling the clamp to perform both horizontal and vertical lifting simultaneously. When changing the lifting method, there is no need to replace the clamp, thus enhancing the convenience of using the clamp. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

Furthermore, the terms "installed," "connected," and "linked" 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 mechanical connection or an electrical connection; they can be directly connected or indirectly connected through an intermediate medium; 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 invention based on the specific circumstances.

[0039] The technical solution in this embodiment of the invention is to solve the above-mentioned technical problems. The overall idea is as follows: By setting the adjustment mechanism 5, compared with the prior art which requires the replacement of the lifting clamp to change the lifting method, by rotating the first clamp 3, the lifting clamp can simultaneously achieve both horizontal and vertical lifting methods, which improves the practicality of the lifting clamp. When changing the lifting method, there is no need to replace the lifting clamp, which improves the convenience of using the lifting clamp.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the above technical solutions in conjunction with the accompanying drawings and specific implementation methods;

[0041] Please see Figures 1 to 6 This invention provides a technical solution for lifting clamps used in mold steel castings:

[0042] A type of lifting clamp for mold steel casting, such as Figure 1 As shown, it includes card slot 1;

[0043] The card holder 1 has a U-shaped structure design. A groove 2 is provided on the outer surface of the front end of the card holder 1. A first caliper 3 and a second caliper 4 are movably connected inside the groove 2. The first caliper 3 and the groove 2 are rotatably connected by an adjustment mechanism 5.

[0044] This invention, by setting an adjustment mechanism 5 and rotating the first clamp 3, enables the lifting clamp to simultaneously achieve both horizontal and vertical lifting methods, improving the practicality of the lifting clamp. When changing the lifting method, there is no need to replace the lifting clamp, thus improving the convenience of using the lifting clamp.

[0045] As one embodiment of the present invention, such as Figures 1 to 3 As shown, the adjustment mechanism 5 includes a bearing ring 51. The front ends of the first caliper 3 and the second caliper 4 are fixedly connected to a connecting ring 6. The outer surfaces of the first caliper 3 and the second caliper 4 away from the connecting ring 6 are both designed with an arc-shaped structure, and the arc-shaped surfaces are provided with a plurality of first tooth grooves 7. The upper and lower outer surfaces of the first caliper 3 and the second caliper 4 are rotatably connected to the groove 2 through the bearing ring 51. A locking block 52 is fixedly connected to one end of the outer surface of the first caliper 3, and the outer surface of the locking block 52 is provided with a second tooth groove 53.

[0046] Because of the different directions of force, horizontal and vertical lifting clamps are used differently and cannot be used interchangeably. This necessitates changing the clamps when changing the lifting method, which is not only inconvenient and time-consuming but also reduces the practicality of the clamps. This invention addresses this by incorporating an adjustment mechanism 5. When vertically lifting a mold plate-shaped steel billet, the opening of the clamp seat 1 faces downwards, and the mold plate-shaped steel billet is engaged between the first clamp 3 and the second clamp 4. Then, the steel cable is connected to the two connecting rings 6, and the billet is lifted using a crane. The steel cable, first clamp 3, and second clamp 4 are then lifted. Under the influence of gravity, they exert a compressive force on the plate-shaped steel billet, thereby clamping the clamps and the plate-shaped steel billet together. By setting the first toothed groove 7 to compress the plate-shaped steel billet, the friction between the clamps and the plate-shaped steel billet is increased, thus achieving the purpose of vertically lifting and transporting the plate-shaped steel billet. When it is necessary to horizontally lift the plate-shaped steel billet, the opening direction of the clamp seat 1 is turned to the left, and then the first clamp 3 is rotated counterclockwise, causing the clamp block 52 to rotate until it is level with the front end of the clamp seat 1. At the designated position, the first clamp 3 and the clamp seat 1 are aligned vertically, clamping the mold plate steel casting between the second clamp 4 and the clamping block 52. Then, the steel cable is connected to the connecting ring 6, and a crane is used to lift the cable, simultaneously lifting the second clamp 4. Under the influence of gravity, the second clamp 4 exerts a compressive force on the mold plate steel casting, thus clamping the clamp and the plate steel casting together. When the second clamp 4 is lifted, the clamp seat 1 deflects, and the first clamp 3 and the clamp seat 1 then support the side of the plate steel casting. The invention enables horizontal lifting by deflecting the plate-shaped steel billet to a horizontal position. By setting the first toothed groove 7 and the second toothed groove 53 to press against the plate-shaped steel billet, the friction between the lifting clamp and the billet is increased. Furthermore, by setting the adjustment mechanism 5 and rotating the first clamp 3, the lifting clamp can simultaneously achieve both horizontal and vertical lifting, improving its practicality. When changing the lifting method, there is no need to replace the lifting clamp, eliminating the need for handling it and enhancing its ease of use.

[0047] As one embodiment of the present invention, such as Figure 2 and Figure 5 As shown, a fixing ring 54 is fixedly connected to one side of the outer surface of the connecting ring 6 connected to the first caliper 3, and a screw hole 55 is provided inside the caliper 1 at the rear end of the bearing ring 51.

[0048] During operation, this invention, by setting a fixing ring 54 and a screw hole 55, allows for horizontal lifting of the plate-shaped steel billet. When the first clamp 3 is rotated counterclockwise to align with the front of the clamp seat 1, the fixing ring 54 rotates accordingly and aligns with the screw hole 55. Bolts are then passed through the screw hole 55 and the fixing ring 54 in sequence to connect them, thereby fixing the first clamp 3 and the clamp block 52. This prevents the first clamp 3 from rotating under force, which could cause the plate-shaped steel billet to detach from the clamp.

[0049] As one embodiment of the present invention, such as Figure 3 As shown, two connecting cylinders 56 are fixedly connected to the upper outer surface of the caliper 1 at the position above the bearing ring 51. Torsion springs 57 are fixedly connected between the first caliper 3, the second caliper 4 and the connecting cylinders 56.

[0050] During operation, this invention, by setting a torsion spring 57, utilizes the torque of the torsion spring 57 to generate a squeezing force on the plate steel casting when clamping it, thereby making the clamping force between the clamp and the plate steel casting more tight. At the same time, the torque of the torsion spring 57 can also limit the first clamp 3 and the second clamp 4, preventing them from rotating when clamping the plate steel casting, thus facilitating operation by the workers.

[0051] As one embodiment of the present invention, such as Figure 4 As shown, a connecting groove 58 is provided on the upper outer surface of the first caliper 3 at the position inside the bearing ring 51. A connecting block 59 is fitted inside the connecting groove 58. The upper outer surface of the connecting block 59 is fixedly connected to the torsion spring 57. A through hole 510 is provided on the upper outer surface of the caliper 1 near the torsion spring 57. The upper end of the torsion spring 57 passes through the through hole 510 and is fixedly connected to a slider 511. The outer surface of the slider 511 is slidably connected to the connecting cylinder 56. A first connecting rod 512 is rotatably connected to the center position of the upper outer surface of the slider 511 via a rotating shaft. A threaded sleeve 513 is fixedly connected to the upper outer surface of the first connecting rod 512. A threaded ring 514 is fixedly connected to the upper outer surface of the connecting cylinder 56 at the position outside the first connecting rod 512. The threaded ring 514 and the threaded sleeve 513 are threadedly connected.

[0052] During operation, the present invention uses a connecting groove 58 and a connecting block 59 to fit together. When the first caliper 3 rotates, it drives the connecting block 59 to rotate, causing the torsion spring 57 to undergo torsional deformation and generate a restoring force in the opposite direction on the first caliper 3, making the first caliper 3 fit tightly against the plate-shaped steel casting. When it is necessary to rotate the first caliper 3, the screw sleeve 513 is rotated to separate it from the screw ring 514. Then, the screw sleeve 513 is moved upward to drive the first connecting rod 512 to move upward. The slider 511 moves upward with the first connecting rod 512, thereby driving the torsion spring 57 and the connecting block 59 to move upward, so that the connecting block 59 separates from the connecting groove 58, thereby relieving the torsional force of the torsion spring 57 on the first caliper 3, allowing the first caliper 3 to rotate smoothly. The screw sleeve 513 and the screw ring 514 are threadedly connected to fix the first connecting rod 512, thereby limiting the vertical movement of the connecting block 59 and preventing the connecting block 59 from separating from the connecting groove 58 under force.

[0053] As one embodiment of the present invention, such as Figure 4 As shown, the connecting block 59 is slidably connected to the connecting groove 58 and the through hole 510 in a regular hexagonal structure, and the slider 511 is also slidably connected to the connecting cylinder 56 in a regular hexagonal structure.

[0054] During operation, this invention prevents relative rotation between the connecting block 59 and the connecting groove 58, and between the slider 511 and the connecting cylinder 56, when the first caliper 3 rotates. This prevents the torsion spring 57 from generating torsional deformation and thus failing to provide restoring force to the first caliper 3. By sliding the through hole 510 and the connecting block 59 in a regular hexagonal structure, the invention also prevents the connecting block 59 from rotating after disengaging from the connecting groove 58. This prevents the connecting block 59 from intersecting with the connecting groove 58, thus preventing the connecting block 59 from smoothly entering the connecting groove 58 after the first caliper 3 resets.

[0055] As one embodiment of the present invention, such as Figure 4 As shown, a second connecting rod 515 is rotatably connected between the slider 511 and the connecting block 59, and the second connecting rod 515 is rotatably connected to the connecting block 59 through a rotating shaft.

[0056] During operation, the present invention connects the slider 511 and the connecting block 59 by setting a second connecting rod 515, so as to prevent the connecting block 59 from being compressed by the torsion spring 57 due to the force, thereby preventing it from disengaging from the connecting groove 58.

[0057] As one embodiment of the present invention, such as Figure 4 As shown, the slider 511 is made of silicon steel, and the top of the inner surface of the connecting cylinder 56 is provided with a magnetic material.

[0058] During operation, the present invention uses a slider 511 made of silicon steel and a magnetic material on the top of the inner surface of the connecting cylinder 56. The slider 511 is fixed by the mutual attraction between the slider 511 and the magnetic material, thereby fixing the connecting block 59 and the first connecting rod 512, preventing the first connecting rod 512 from sliding up and down under force, and making it easier for the operator to operate.

[0059] As one embodiment of the present invention, such as Figure 5 and Figure 6 As shown, an arc-shaped groove 516 is provided on the lower outer surface of the first caliper 3 at the position inside the bearing ring 51. A protruding rod 517 is fixedly connected to the bottom end of the inner surface of the groove 2 near the arc-shaped groove 516. The protruding rod 517 is slidably connected to the arc-shaped groove 516.

[0060] During operation, the present invention limits the first clamp 3 by setting the protruding rod 517 and the arc-shaped groove 516 to slide together. When the first clamp 3 rotates counterclockwise, the arc-shaped groove 516 rotates accordingly, and the protruding rod 517 and the arc-shaped groove 516 slide relative to each other. When the arc-shaped groove 516 rotates to the end and engages with the protruding rod 517, the fixing ring 54 and the screw hole 55 are in the same position, which facilitates the fixing of the two and enables the clamp to realize the horizontal lifting function. When the first clamp is rotated clockwise to reset it, the arc-shaped groove 516 rotates to the other end and engages with the protruding rod 517. At this time, the connecting block 59 and the connecting groove 58 are in the same position, which facilitates the connecting block 59 to smoothly enter the connecting groove 58 and connect the first clamp 3 to the torsion spring 57.

[0061] As one embodiment of the present invention, such as Figure 1 As shown, both the first caliper 3 and the second caliper 4 are made of high manganese steel, which can improve their wear resistance.

[0062] When in operation, high manganese steel has the advantage of good wear resistance. By making the first caliper 3 and the second caliper 4 from high manganese steel, the damage caused by friction is reduced and the service life of the two is improved.

[0063] Usage: This invention, through the setting of adjustment mechanism 5, when it is necessary to vertically lift the mold plate steel casting, the opening direction of the clamping seat 1 is downward, and the mold plate steel casting is clamped between the first clamp 3 and the second clamp 4. Then, the steel cable is connected to the two connecting rings 6, and the steel cable is lifted by a crane. The first clamp 3 and the second clamp 4 are lifted accordingly. Under the influence of gravity, the two generate a compressive force on the mold plate steel casting, thereby clamping the clamps and the plate steel casting together, thus achieving the purpose of vertically lifting and transporting the plate steel casting. When it is necessary to horizontally lift the plate steel casting... When the opening of the clamp seat 1 is turned to the left, the first clamp 3 is rotated counterclockwise, causing the clamp block 52 to rotate to a position parallel to the front end of the clamp seat 1. At this time, the first clamp 3 and the clamp seat 1 are on the same vertical line. The mold plate steel casting is clamped between the second clamp 4 and the clamp block 52. Then the steel cable is connected to the connecting ring 6. The steel cable is lifted by the crane, and the second clamp 4 is lifted accordingly. Under the influence of gravity, the second clamp 4 generates a squeezing force on the mold plate steel casting, thereby clamping the clamp and the plate steel casting tightly together to achieve the purpose of horizontally lifting and transporting the plate steel casting.
