Description

Technical Field

[0001] This utility model relates to the technical field of continuous casting machine equipment, and in particular to an auxiliary device for rapid assembly of continuous casting machine rollers. Background Technology

[0002] The process of continuously casting molten steel at high temperatures into billets with specific cross-sectional shapes and dimensions is called continuous steel casting. The equipment required to complete this process is called a complete set of continuous casting equipment. The electromechanical-hydraulic integration of the steel casting equipment, the continuous casting machine body, the cutting area equipment, and the dummy bar collection and conveying equipment constitutes the core equipment of continuous steel casting, which is conventionally referred to as the continuous casting machine.

[0003] The continuous casting roll is a crucial component that enables the continuous operation of a continuous casting machine. A complete continuous casting machine consists of at least hundreds of continuous casting rolls. The continuous casting roll is generally composed of a mandrel and a roller. The roller and the mandrel are interference-fitted and connected to the mandrel via a keyway through which they are driven. Traditionally, when assembling the continuous casting roll, this interference fit is achieved by manually aligning and then pressing it in with hammers or hydraulic cylinders. However, the coaxiality error between the mandrel and the roller is relatively large, making assembly very difficult and prone to wear and damage.

[0004] Therefore, it is necessary to provide a new auxiliary device for rapid assembly of continuous casting machine rollers to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 7This utility model provides a rapid assembly auxiliary device for continuous casting machine rollers, which includes:

[0031] The base 1 and the fixed platform 2 fixedly installed in the middle of the base 1, the fixed platform 2 having a placement groove 201 for placing the roller;

[0032] The main hydraulic rod 7 is embedded in the base 1 and located below the fixed platform 2;

[0033] Two sets of electric rods 3 are provided. The two sets of electric rods 3 are symmetrically installed on the upper surface of the fixed platform 2. The telescopic ends of the two sets of electric rods 3 are fixedly installed with a pressing mechanism 4. The pressing mechanism 4 includes a pressing frame 41, which is fixedly connected to the telescopic ends of the two sets of electric rods 3. The bottom end of the pressing frame 41 is rotatably installed with a pressing roller 42. The top end of the pressing frame 41 is fixedly installed with a secondary hydraulic rod 43. The telescopic end of the secondary hydraulic rod 43 is fixedly installed with a C-shaped frame 44. A clamping component 45 is installed on the C-shaped frame 44.

[0034] There are two support rods 5, which are symmetrically installed on the fixed platform 2, and auxiliary support components 6 are installed on the two support rods 5.

[0035] The clamping mechanism 8, used for clamping the mandrel, is installed at the telescopic end of the main hydraulic rod 7.

[0036] It should be noted that during use, the roller is placed in the placement groove 201, and then the electric lever 3 is controlled to drive the pressure frame 41 to move downward until the roller is pressed and fixed in the placement groove 201 by the pressure roller 42. Then, the clamping assembly 45 is activated to clamp the roller and place it on the fixed platform 2, which facilitates the positioning of the pressing stroke later. Then, the mandrel is fixed to the roller coaxially by the auxiliary support 6 and the clamping mechanism 8. Then, the main hydraulic rod 7 is controlled to retract to automatically align and press the mandrel into the roller. The pressing is very fast.

[0037] In the embodiments of this utility model, please refer to Figures 1 to 7 The clamping assembly 45 includes a bidirectional threaded rod 451 rotatably mounted on a C-frame 44. A servo motor 452 for driving the bidirectional threaded rod 451 to rotate is mounted on the C-frame 44. Guide rods 453 are fixedly mounted on both sides of the bidirectional threaded rod 451 on the C-frame 44. Slider blocks 454 are symmetrically threaded on the bidirectional threaded rod 451. The sliders 454 have through holes that slide with the guide rods 453. Pressure plates 455 are mounted on each slider 454.

[0038] Among them, two sliders 454 are symmetrically installed on the bidirectional threaded rod 451. The bottom end of the pressure plate 455 of the slider 454 away from the auxiliary support 6 is equipped with an insert 456, which is adapted to the keyway of the roller.

[0039] It should be noted that when the clamping assembly 45 is used, after the pressure roller 42 presses the roller into the placement groove 201, the auxiliary hydraulic rod 43 is started to drive the C-shaped frame 44 to move until the insertion block 456 of the pressure plate 455 is aligned with the keyway of the roller. Then, the servo motor 452 is started to drive the bidirectional threaded rod 451 to rotate. When rotating, the two sliders 454 drive the pressure plate 455 to slide towards each other until they contact the upper ends of the roller and clamp the roller into the placement groove 201, thus completing the centering clamping.

[0040] In the embodiments of this utility model, please refer to Figures 1 to 7 The auxiliary support 6 includes a movable platform 61, which is slidably mounted on two support rods 5. A connecting spring 62 is sleeved on the two support rods 5. One end of the connecting spring 62 is fixedly connected to the fixed platform 2, and the other end of the connecting spring 62 is fixedly connected to the movable platform 61. The movable platform 61 has a second placement groove 601, in which a pad 63 is provided. The bottom end of the pad 63 is symmetrically equipped with a plug rod 64 that is inserted and engaged with the movable platform 61. Several support rollers 65 are installed on the pad 63. The bottom end of the movable platform 61 is threaded with an adjusting screw 66 that is in contact with the bottom of the pad 63.

[0041] It should be noted that when the auxiliary support 6 is in use, the adjustment screw 66 is turned to drive the pad 63 to move the insertion rod 64 upward until the top of the support roller 65 on the moving pad 63 is flush with the bottom of the mandrel when it is coaxial with the roller, so as to support the coaxial placement of the mandrel.

[0042] In the embodiments of this utility model, please refer to Figures 1 to 7 The clamping mechanism 8 includes a spacer plate 81, which is fixedly installed on the telescopic end of the main hydraulic rod 7. A lower clamping piece 82 is installed on the spacer plate 81. An installation frame 811 is installed on the inner side of the spacer plate 81. Electric rods 83 are symmetrically installed on the installation frame 811. An upper clamping piece 84 is fixedly installed on the telescopic ends of the two electric rods 83.

[0043] Among them, the outer side of the lower clip 82 is provided with an arc-shaped limiting plate 821.

[0044] It should be noted that: the spacer plate 81 is configured to be coaxially aligned with the mandrel and the roller. The inner diameter of the lower clamping plate 82 and the upper clamping plate 84 is equal to the outer diameter of the mandrel. After one end of the mandrel is placed on the lower clamping plate 82, the control electric lever 83 drives the upper clamping plate 84 to clamp the mandrel. Then, when the main hydraulic lever 7 retracts, the arc-shaped limit plate 821 pushes the mandrel into the roller, completing the alignment and pressing.

[0045] The working principle of the quick assembly auxiliary device for continuous casting machine rollers provided by this utility model is as follows:

[0046] In use, the roller is placed in the placement groove 201, and then the electric lever 3 is controlled to drive the pressure frame 41 to move downward until the roller is pressed and fixed in the placement groove 201 by the pressure roller 42. The auxiliary hydraulic lever 43 is started to drive the C-shaped frame 44 to move until the insertion block 456 of the pressure plate 455 is aligned with the keyway of the roller. Then the servo motor 452 is started to drive the bidirectional threaded rod 451 to rotate. When rotating, the two sliders 454 drive the pressure plate 455 to slide towards each other until they contact the upper ends of the roller and center and clamp the roller in the placement groove 201, completing the centering clamping.

[0047] Then, by turning the adjusting screw 66, the pad 63 is driven to move the insertion rod 64 upward until the top of the support roller 65 on the moving pad 63 is flush with the bottom of the mandrel when it is coaxial with the roller, thus supporting the coaxial placement of the mandrel. Then, one end of the mandrel is placed on the support roller 65 and the other end is placed on the lower clamping plate 82. Then, the electric lever 83 is controlled to drive the upper clamping plate 84 to press and clamp the mandrel. Then, when the main hydraulic rod 7 retracts, the arc-shaped limit plate 821 pushes the mandrel into the roller, completing the alignment and pressing.

[0048] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
