Description

Technical Field

[0001] This utility model belongs to the field of hydraulic technology for heating furnaces, specifically a hydraulic device for a metal rod heating furnace. Background Technology

[0002] A heating furnace is a device specifically designed for heating products and workpieces. In the metallurgical industry, it is mainly used to heat metal materials to a certain temperature for subsequent processing.

[0003] Currently, most metal materials are heated using walking beam furnaces. Walking beam furnaces use hydraulic equipment at the furnace bottom in conjunction with support beams to move the metal material forward step by step in a rising, advancing, falling, and retreating motion, allowing the metal material to be continuously heated and fed in and out. However, existing hydraulic equipment for heating furnaces often requires two sets of hydraulic cylinders to realize the forward and backward movement and lifting and lowering of the material. Therefore, a relatively complex control system is needed to control the operation of the two sets of hydraulic cylinders to make them work together, which is quite inconvenient.

[0004] Therefore, this utility model provides a hydraulic device for a metal rod heating furnace. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A hydraulic device for a metal rod heating furnace, comprising a support frame; a lower support block slidably connected to the middle of the support frame; a top block installed in the middle of the support frame; a hydraulic cylinder fixedly connected to the side wall of the support frame; a connecting groove formed on the side wall of the top block; a connecting rod fixedly connected to the output end of the hydraulic cylinder; the connecting rod slidably connected to the inside of the connecting groove; a limiting plate slidably connected to the bottom of the top block; a slot formed in the middle of the lower support block; a top plate rotatably connected to the bottom of the support frame; a top rod fixedly connected to the bottom of the support frame; multiple inclined slots formed at the bottom of the support frame; and multiple inclined blocks fixedly connected to the top of the support frame. With the above structure, only one hydraulic cylinder needs to be repeatedly and orderly operated to drive the metal plate in the heating furnace to move intermittently, without the need for various commands. Only the repetitive operation interval of one hydraulic cylinder needs to be set, making it convenient to use.

[0007] Preferably, a pair of guide rods are slidably connected to the side wall of the support frame; both ends of the pair of guide rods are fixedly connected to a fixing plate; multiple springs are fixedly connected to the outer side wall of the support frame; the other ends of the multiple springs are fixedly connected to the side wall of the fixing plate; through the above structure, the occurrence of collision between the top block and the support frame can be reduced, and the impact of vibration caused by the collision on the equipment components can be reduced.

[0008] Preferably, the top of the top block is fixedly connected to multiple pairs of connecting blocks; each pair of connecting blocks has a detachable insert rod installed in the middle; and each insert rod has a detachable lifting plate installed in the middle. Through the above structure, the device can perform step-by-step movement operation on metal rods of different diameters, reducing the occurrence of metal rod slippage and improving the applicability of the device.

[0009] Preferably, a limiting block is fixed to the inner side wall of the support frame; the limiting block and the guide rod are disposed on the same side wall of the support frame; with the above structure, when the top block moves laterally under the pressure of the lower support block, the top block can be stopped at a designated position without deviation of the stopping position due to the elastic force of the spring, so that after the hydraulic cylinder extends to the fixed position, the limiting plate can slide into the slot more accurately, thereby improving the fit stability of the components and reducing the occurrence of component fit errors.

[0010] Preferably, a circular roller is rotatably connected to the side wall of the limiting block; a circular roller is also rotatably connected to the side wall of a fixed plate near the lower support block; through the above structure, the sliding friction on the side wall of the top block can be transformed into rolling friction, reducing the wear on the component, and thus reducing the occurrence of unstable fit after component wear.

[0011] Preferably, a pair of bushings are rotatably connected to the middle of the connecting rod; the pair of bushings are located at both ends of the connecting rod; through the above structure, the sliding friction between the connecting groove and the connecting rod can be transformed into rolling friction, further reducing the wear on the components and further improving the stability of the equipment.

[0012] Preferably, a limiting rod is fixed to the bottom of the support frame; the limiting rod is located on the side of the top plate away from the top rod; through the above structure, the occurrence of the top plate flipping to the side away from the top rod can be reduced, thereby reducing the occurrence of the top plate failing to stably push the limiting plate out of the slot, and improving the fit stability of the components.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The hydraulic equipment for a metal rod heating furnace described in this utility model, through the arrangement of a support frame, lower support block, top block, hydraulic cylinder, connecting groove, connecting rod, limiting plate, slot, top plate, top rod, inclined groove, and inclined block, allows the metal plate inside the heating furnace to move intermittently by repeatedly and orderly operating a single hydraulic cylinder. It does not require the coordination of various commands; only the repeated operation interval of a single hydraulic cylinder needs to be set, making it quite convenient to use.

[0015] 2. The hydraulic equipment for a metal rod heating furnace described in this utility model, through the arrangement of guide rods, fixing plates, and springs, can reduce the occurrence of collisions between the top block and the support frame, and reduce the impact of vibrations caused by collisions on the equipment components.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3As shown, a hydraulic device for a metal rod heating furnace according to an embodiment of the present invention includes a support frame 1; a lower support block 12 is slidably connected to the middle of the support frame 1; a top block 13 is installed in the middle of the support frame 1; a hydraulic cylinder 14 is fixedly connected to the side wall of the support frame 1; a connecting groove 15 is opened in the side wall of the top block 13; a connecting rod 16 is fixedly connected to the output end of the hydraulic cylinder 14; the connecting rod 16 is slidably connected to the inside of the connecting groove 15; a limit plate 17 is slidably connected to the bottom of the top block 13; a slot 18 is opened in the middle of the lower support block 12; a top plate 19 is rotatably connected to the bottom of the support frame 1; a top rod 110 is fixedly connected to the bottom of the support frame 1; and multiple inclined grooves 111 are opened in the bottom of the support frame 1. Multiple inclined blocks 112 are fixed to the top of the support frame 1. During operation, the hydraulic cylinder 14 is activated to push the lower support block 12 away from the hydraulic cylinder 14, causing the lower support block 12 to move the top block 13 to the side wall of the support frame 1. At this time, the top block 13 is blocked by the side wall of the support frame 1 and cannot continue to move away from the hydraulic cylinder 14. The lower support block 12 continuously presses the top block 13, and the inclined surface at the bottom of the top block 13 interacts with the inclined surface at the top of the lower support block 12, causing the top block 13 to rise vertically and lift the metal rod above it from the heating furnace support. At the same time, the lower support block 12 continues to move downwards from the top block 13. After reaching the corresponding position, the limiting plate... 17 will slide into the slot 18. At this time, the retracting hydraulic cylinder 14 drives the lower support block 12 to move towards the hydraulic cylinder 14. Since the limiting plate 17 is located inside the slot 18, it will drive the top block 13 to move synchronously, so that the metal rod in the heating furnace moves synchronously. When the roller on the side wall of the lower support block 12 moves into the top rod 110, the top plate 19 will press against the bottom end of the limiting plate 17 inserted into the slot 18 and push the limiting plate 17 upward out of the top opening of the slot 18. At this time, the top block 13 will slide down the inclined surface of the lower support block 12, and the rollers on both sides of the top block 13 will fall on the inclined surface of the inclined block 112, so that the top block 13 moves along the support frame 1. The top slides to the initial position. At the same time, when the roller on the side wall of the lower support block 12 enters the inclined groove 111, the metal rod lifted by the top block 13 will descend with the lower support block 12 and the top block 13 and fall back onto the support in the heating furnace. Compared with the original position, the metal rod has moved a certain distance. By repeatedly and orderly extending and retracting the hydraulic cylinder 14, the stepping operation of the metal rod in the heating furnace can be completed. With the above structure, only one hydraulic cylinder 14 can be used to repeatedly and orderly move the metal plate in the heating furnace intermittently. It does not require the coordination of various commands. Only the repeated running interval of the hydraulic cylinder 14 needs to be set, which is more convenient to use.

[0024] like Figures 1 to 4As shown, a pair of guide rods 2 are slidably connected to the side wall of the support frame 1; both ends of the pair of guide rods 2 are fixedly connected to a fixing plate 21; multiple springs 22 are fixedly connected to the outer side wall of the support frame 1; the other ends of the multiple springs 22 are fixedly connected to the side wall of the fixing plate 21; during operation, after the top block 13 slides off the lower support block 12 and the rollers on both sides of the top block 13 fall onto the support frame 1, the top block 13 will slide towards the fixing plate 21. After the side wall of the top block 13 contacts the fixing plate 21, the top block 13 will squeeze the fixing plate 21, the multiple springs 22 will be stretched, and the kinetic energy of the top block 13 will be converted into the elastic potential energy of the springs 22, so that the top block 13 will not easily collide with the side wall of the support frame 1. Through the above structure, the occurrence of collision between the top block 13 and the support frame 1 can be reduced, and the impact of the vibration caused by the collision on the equipment components can be reduced.

[0025] like Figures 1 to 4 As shown, multiple pairs of connecting blocks 3 are fixedly connected to the top of the top block 13; a rod 31 is detachably installed in the middle of each pair of connecting blocks 3; a lifting plate 32 is detachably installed in the middle of each rod 31; during operation, the spacing of the multiple lifting plates 32 can be adjusted according to the diameter of the metal rod, and the rod 31 is inserted into the corresponding connecting block 3 to limit the lifting plate 32, thereby reducing the occurrence of the metal rod slipping due to its large diameter when the metal rod is lifted and moved. Through the above structure, the equipment can perform step-by-step movement operation on metal rods of different diameters, reduce the occurrence of metal rod slipping, and improve the applicability of the device.

[0026] like Figures 1 to 4 As shown, a limiting block 4 is fixed to the inner wall of the support frame 1; the limiting block 4 and the guide rod 2 are set on the same side wall of the support frame 1; during operation, when the top block 13 is pressed by the lower support block 12 and moves towards the fixed plate 21, the spring 22 will be stretched, and the fixed plate 21 will move synchronously with the top block 13. By setting the limiting block 4, the side wall of the top block 13 will stop moving laterally when it abuts against the limiting block 4. At this time, the longitudinal position of the limiting plate 17 is fixed, so that after the lower support block 12 moves to the corresponding position under the drive of the hydraulic cylinder 14, the limiting plate 17 can accurately fall into the slot 18. Through the above structure, when the top block 13 is pressed by the lower support block 12 and moves laterally, the top block 13 can stop at the specified position without deviation of the stopping position due to the elasticity of the spring 22. After the hydraulic cylinder 14 extends to the fixed position, the limiting plate 17 can slide into the slot 18 more accurately, improving the fit stability of the components and reducing the occurrence of component fit errors.

[0027] like Figures 1 to 4As shown, a roller 5 is rotatably connected to the side wall of the limiting block 4; a roller 5 is also rotatably connected to the side wall of a fixed plate 21 near the lower support block 12; during operation, when the top block 13 abuts against the limiting block 4 and rises with the continuous pressure of the lower support block 12, the side wall of the top block 13 will roll with multiple rollers 5. Through the above structure, the sliding friction on the side wall of the top block 13 can be transformed into rolling friction, reducing the wear on the component, and thus reducing the occurrence of unstable fit after component wear.

[0028] like Figures 1 to 3 As shown, a pair of sleeve wheels 6 are rotatably connected to the middle of the connecting rod 16; the pair of sleeve wheels 6 are located at both ends of the connecting rod 16 respectively; through the above structure, the sliding friction between the connecting groove 15 and the connecting rod 16 can be transformed into rolling friction, further reducing the wear on the components and further improving the stability of the equipment.

[0029] like Figure 3 As shown, the bottom of the support frame 1 is fixedly connected to a limiting rod 7; the limiting rod 7 is located on the side of the top plate 19 away from the top rod 110; through the above structure, the occurrence of the top plate 19 flipping to the side away from the top rod 110 can be reduced, thereby reducing the occurrence of the top plate 19 failing to stably push the limiting plate 17 out of the slot 18, and improving the fit stability of the components.

[0030] During operation, the hydraulic cylinder 14 is activated, pushing the lower support block 12 away from the hydraulic cylinder 14. This causes the lower support block 12 to move the top block 13 to the side wall of the support frame 1. At this point, the top block 13 is blocked by the side wall of the support frame 1 and cannot continue to move away from the hydraulic cylinder 14. The lower support block 12 continuously presses against the top block 13, causing the inclined surface at the bottom of the top block 13 to interact with the inclined surface at the top of the lower support block 12. This causes the top block 13 to rise vertically, lifting the metal rod above it from the heating furnace support. Simultaneously, the lower support block 12 continues to move downwards from the top block 13. After reaching the corresponding position, the limiting plate 17 slides into the slot 18. At this point, the hydraulic cylinder 14 retracts, causing the lower support block 12 to move towards the hydraulic cylinder 14. When the limiting plate 17 is located inside the slot 18, it will drive the top block 13 to move synchronously, causing the metal rod inside the heating furnace to move synchronously. When the roller on the side wall of the lower support block 12 moves into the top rod 110, the top plate 19 will press against the bottom end of the limiting plate 17 inserted into the slot 18 and push the limiting plate 17 upward out of the top opening of the slot 18. At this time, the top block 13 will slide down along the inclined surface of the lower support block 12, and the rollers on both sides of the top block 13 will fall on the inclined surface of the inclined block 112, so that the top block 13 slides along the top of the support frame 1 to the initial position. At the same time, when the roller on the side wall of the lower support block 12 sinks into the inclined groove 111, the metal rod lifted by the top block 13 will fall down with the lower support block 12 and the top block 13 and fall back into the heating furnace. On the internal support, the metal rod has moved a certain distance from its original position. Through the repeated and orderly extension and retraction of the hydraulic cylinder 14, the stepping operation of the metal rod inside the heating furnace can be completed. After the top block 13 slides off the lower support block 12 and the rollers on both sides of the top block 13 land on the support frame 1, the top block 13 will slide towards the fixed plate 21. After the side wall of the top block 13 contacts the fixed plate 21, the top block 13 will compress the fixed plate 21, stretching multiple springs 22 and converting the kinetic energy of the top block 13 into the elastic potential energy of the springs 22, preventing the top block 13 from easily colliding with the side wall of the support frame 1. The spacing of the multiple lifting plates 32 can be adjusted according to the diameter of the metal rod, and the insertion rod 31 is inserted into the corresponding connecting block 3 to support the top. The lifting plate 32 is positioned to limit the movement of the metal rod, thereby reducing the possibility of the metal rod slipping due to its large diameter when it is lifted and moved. When the top block 13 is pressed by the lower support block 12 and moves towards the fixed plate 21, the spring 22 is stretched, and the fixed plate 21 moves synchronously with the top block 13. By setting the limiting block 4, the side wall of the top block 13 stops moving laterally when it abuts against the limiting block 4. At this time, the longitudinal position of the limiting plate 17 is fixed, so that after the lower support block 12 moves to the corresponding position under the drive of the hydraulic cylinder 14, the limiting plate 17 can accurately fall into the slot 18. When the top block 13 abuts against the limiting block 4 and rises with the continuous pressure of the lower support block 12, the side wall of the top block 13 will roll with multiple rollers 5.
