Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a forging die lifting frame. Background Technology

[0002] Forging dies are specialized tools that shape billets into forgings. They are essential key process equipment in forging production. Each die has a cavity (also known as a die chamber) of a certain shape and size, which is wholly or partially equivalent to the forging to be manufactured. Through the precise design of the die chamber, forging dies ensure that the forgings achieve the required geometric shape and dimensional accuracy. During the assembly and disassembly of forging dies, because dies are generally heavy and the installation height of dies varies among different presses, a lifting frame is needed to improve the ease of loading and unloading forging dies.

[0003] The patent document with publication number CN217142193U discloses a forging die lifting device, including a movable base, a lifting platform on the movable base, and a scissor arm between the lifting platform and the movable base; a horizontal upper sliding groove is provided at one end of the bottom of the lifting platform, and the hinge shaft at the end of one arm of the upper part of the scissor arm can slide in the horizontal upper sliding groove.

[0004] The aforementioned lifting device still has some problems in use. This lifting device uses a scissor structure to adjust the lifting of the mold and uses rollers to support the mold. At the same time, the lifting device uses a limit rod to limit and protect the mold. However, the position of the limit rod is fixed and cannot guarantee that it fits the mold. During the process of the lifting device moving the mold, the mold is prone to move above the rollers, which will cause collision between the mold and the limit rod, posing a safety problem. Therefore, a forging mold lifting frame is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, traditional lifting devices use a scissor mechanism to adjust the lifting of the mold and use rollers to support the mold. At the same time, the lifting device uses a limiting rod to limit and protect the mold. However, the limiting rod is fixed in position and cannot guarantee that it fits the mold. During the process of the lifting device moving the mold, the mold is prone to move above the roller, which can cause collisions between the mold and the limiting rod, posing a safety problem. This utility model proposes a forging mold lifting frame.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The forging mold lifting frame of this utility model includes a scissor support frame, a support plate is fixedly connected to the top of the scissor support frame, a first handwheel is provided at one end of the support plate, and a rear guard plate and a front guard plate are provided on both sides of the support plate. A second handwheel is provided at one end of the rear guard plate, and a reinforcing mechanism is provided on one side of the opposite surfaces of the two rear guard plates and on one side of the opposite surfaces of the two front guard plates. A double-acting screw is fixedly connected to one side of the first handwheel. A pair of first sliders are sleeved on the outer side of the double-acting screw, and two rotating threads of the same length but opposite direction are opened on the outer surface of the double-acting screw. An adjusting screw is fixedly connected to one side of the second handwheel, and a second slider is sleeved on the outer side of the adjusting screw.

[0007] Preferably, the reinforcement mechanism includes two symmetrically arranged reinforcement rods, one end of which is fixedly connected to a connector, and one end of the other reinforcement rod is provided with an adjusting rod, the two ends of which are respectively fixedly connected to a threaded ring and a limiting ring.

[0008] Preferably, the bidirectional lead screw is movably connected to the support plate, the adjusting lead screw is movably connected to the rear guard plate, a connecting plate is fixedly connected to one side of the first slider, and a pair of connecting rods are fixedly connected to one side of the second slider.

[0009] Preferably, the first slider is slidably connected to the connecting plate and the support plate at the connection point, and the connecting plate is fixedly connected to the rear guard plate; the second slider is slidably connected to the connecting rod and the rear guard plate at the connection point, and one end of the connecting rod is fixedly connected to the front guard plate.

[0010] Preferably, both the front guard plate and the rear guard plate are L-shaped, with the reinforcing rod near the front side of the support plate being movably connected to the front guard plate, and the reinforcing rod near the rear side of the support plate being movably connected to the rear guard plate.

[0011] Preferably, the threaded ring is threadedly connected to the adjacent reinforcing rod, the limiting ring is fitted with the end face of the connector, and a threaded sleeve is fitted on the outer side of the adjusting rod, which is threadedly connected to the connector.

[0012] The advantages of this utility model are: 1. This utility model uses a first handwheel to drive a bidirectional lead screw to rotate, and a second handwheel to drive an adjusting lead screw to rotate. The rotation of the bidirectional lead screw causes the two first sliders and the two connecting plates to move synchronously in opposite directions, thereby causing the two rear guard plates to move in opposite directions, so that the rear guard plates fit against the top corner of the rear side of the mold. At the same time, the rotation of the adjusting lead screw causes the second slider to move the connecting rod, thereby moving the front guard plate, so that the front guard plate fits against the top corner of the front side of the mold. Through the cooperation of the four guard plates, the mold is limited. This application is provided with a set of guard plates that are symmetrical in pairs, and the front-to-back distance and horizontal distance of the guard plates can be adjusted to effectively limit the mold, reduce the occurrence of mold collision problems, and ensure the safety of mold loading and unloading. 2. This utility model adjusts the support plates inward to make the two pairs of support plates horizontally symmetrical. By rotating the adjusting rod, the adjusting rod is moved outward through the threaded ring, so that the limiting ring fits with the end face of the connector. Then, the threaded sleeve is rotated to connect with the connector, thus fixing the position of the two reinforcing rods. The two reinforcing rods on the front side connect the two front guard plates into a whole, and the two reinforcing rods on the rear side connect the two rear guard plates into a whole. By setting the reinforcing components, multiple guard plates can be connected into a whole, improving the overall integrity and stability of the guard plates and further ensuring the limiting effect of the guard plates on the mold.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 one Figure 5 As shown, a forging die lifting frame includes a scissor support frame 1. A support plate 2 is fixedly connected to the top of the scissor support frame 1. A first handwheel 3 is provided at one end of the support plate 2. A rear guard plate 4 and a front guard plate 5 are provided on both sides of the support plate 2. A second handwheel 6 is provided at one end of the rear guard plate 4. A reinforcing mechanism 7 is provided on one side of the opposite surfaces of the two rear guard plates 4 and on one side of the opposite surfaces of the two front guard plates 5. A bidirectional lead screw 8 is fixedly connected to one side of the first handwheel 3. A pair of first sliders 9 are sleeved on the outer side of the bidirectional lead screw 8. Two rotating threads of the same length and opposite direction are opened on the outer surface of the bidirectional lead screw 8. An adjusting lead screw 11 is fixedly connected to one side of the second handwheel 6. A second slider 12 is sleeved on the outer side of the adjusting lead screw 11. During operation, traditional lifting devices use a scissor mechanism to adjust the lifting of the mold, with rollers supporting the mold. These devices also use limit rods to protect the mold. However, the fixed position of the limit rods prevents them from fully engaging with the mold. As the lifting device moves the mold, it can easily move above the rollers, causing collisions between the mold and the limit rods, posing a safety risk. To address this, the horizontal spacing of the guard plates is adjusted by rotating the bidirectional lead screw 8, and the front-to-back spacing is adjusted by rotating the lead screw 11. This allows the two rear guard plates 4 and two front guard plates 5 to engage with the four corners of the mold, effectively limiting its movement.

[0018] Furthermore, the reinforcement mechanism 7 includes two symmetrically arranged reinforcement rods 14, one end of which is fixedly connected to a connector 15, and one end of the other reinforcement rod 14 is provided with an adjusting rod 16, with a threaded ring 18 and a limiting ring 19 fixedly connected to both ends of the adjusting rod 16 respectively. During operation, a reinforcement mechanism 7 is provided to improve the integrity and stability of the guard plate and ensure the limiting effect.

[0019] Furthermore, the bidirectional lead screw 8 is movably connected to the support plate 2, the adjusting lead screw 11 is movably connected to the rear guard plate 4, one side of the first slider 9 is fixedly connected to the connecting plate 10, and one side of the second slider 12 is fixedly connected to a pair of connecting rods 13. During operation, the scissor lift support 1 is moved to the loading location of the mold. The scissor lift support 1 is activated to drive the support plate 2 to move vertically, so that the support plate 2 is located on one side of the mold. Then the mold is moved to the top surface of the support plate 2. The mold is limited by the roller on the top surface of the support plate 2. Then the first handwheel 3 drives the bidirectional lead screw 8 to rotate, and the second handwheel 6 drives the adjusting lead screw 11 to rotate.

[0020] Furthermore, the first slider 9 is slidably connected to the connecting plate 10 and the support plate 2 at the connection point, and the connecting plate 10 is fixedly connected to the rear guard plate 4. The second slider 12 is slidably connected to the connecting rod 13 and the rear guard plate 4 at the connection point, and one end of the connecting rod 13 is fixedly connected to the front guard plate 5. During operation, the rotation of the bidirectional lead screw 8 causes the two first sliders 9 and the two connecting plates 10 to move synchronously in opposite directions, which in turn drives the two rear guard plates 4 to move in opposite directions, so that the rear guard plates 4 fit against the top corner of the mold. At the same time, the rotation of the lead screw 11 is adjusted to cause the second slider 12 to move the connecting rod 13, which in turn drives the front guard plate 5 to move, so that the front guard plate 5 fits against the top corner of the mold.

[0021] Furthermore, both the front guard plate 5 and the rear guard plate 4 are L-shaped. The reinforcing rod 14 near the front side of the support plate 2 is movably connected to the front guard plate 5, and the reinforcing rod 14 near the rear side of the support plate 2 is movably connected to the rear guard plate 4. During operation, after the protective plate is attached to the side of the mold, the support plate 2 is adjusted inward so that the two pairs of support plates 2 are set horizontally symmetrically.

[0022] Furthermore, the threaded ring 18 is threadedly connected to the adjacent reinforcing rod 14, the limiting ring 19 is fitted with the end face of the connector 15, and the outer side of the adjusting rod 16 is fitted with a threaded sleeve 17, which is threadedly connected to the connector 15. During operation, rotating the adjusting rod 16 moves it outward through the threaded ring 18, causing the limiting ring 19 to fit against the end face of the connector 15. Then, rotating the threaded sleeve 17 connects it to the connector 15, fixing the positions of the two reinforcing rods 14. The two reinforcing rods 14 on the front side connect the two front guard plates 5 into a whole, and the two reinforcing rods 14 on the rear side connect the two rear guard plates 4 into a whole.

[0023] Working principle: The scissor lift support 1 is moved to the loading position of the mold. The scissor lift support 1 is activated, causing the support plate 2 to move vertically, so that the support plate 2 is located on one side of the mold. Then, the mold is moved to the top surface of the support plate 2. The roller on the top surface of the support plate 2 limits the mold. Then, the first handwheel 3 drives the bidirectional lead screw 8 to rotate, and the second handwheel 6 drives the adjusting lead screw 11 to rotate. The rotation of the bidirectional lead screw 8 causes the two first sliders 9 and the two connecting plates 10 to move synchronously in opposite directions, thereby causing the two rear guard plates 4 to move in opposite directions, so that the rear guard plates 4 are in contact with the top corner of the rear side of the mold. At the same time, the rotation of the adjusting lead screw 11 causes the second slider 12 to move the connecting rod 13, thereby moving the front guard plate 5, so that the front guard plate 5 is in contact with the top corner of the front side of the mold. Through the cooperation of the four guard plates, the mold is limited, reducing the occurrence of mold collision problems.

[0024] After the guard plate is adjusted, adjust the support plate 2 inward so that the two pairs of support plates 2 are horizontally symmetrical. Rotate the adjusting rod 16 and move it outward through the threaded ring 18. Then the limiting ring 19 fits with the end face of the connector 15. Then rotate the threaded sleeve 17 and thread it to the connector 15. The positions of the two reinforcing rods 14 are fixed. The two reinforcing rods 14 on the front side connect the two front guard plates 5 into a whole, and the two reinforcing rods 14 on the rear side connect the two rear guard plates 4 into a whole. This improves the overall integrity and stability of the guard plate and further ensures the limiting effect of the guard plate on the mold. Then push the scissor support frame 1 to the unloading point of the mold to complete the mold handling work.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
