Technical Field

[0001] The utility model belongs to the technical field of steel rolling rolls, and relates to a demoulding device, in particular to a rapid demoulding device for a composite high-speed steel rolling roll. Background Art

[0002] The application of high-speed steel rolling rolls is an important part of the development of modern steel rolling production, and it is another major revolution in the development of the steel industry after microalloying and controlled rolling and cooling technologies. High-speed steel rolling rolls have been widely used in steel rolling production in fields such as sheet metal, section steel, bars and wires in Japan, and are used not only for work rolls but also for backup rolls. The good wear resistance of high-speed steel rolling rolls is inseparable from its obvious differences from traditional rolling rolls.

[0003] After retrieval, as disclosed in a Chinese patent document, a rapid demoulding device for a centrifugally cast composite high-speed steel rolling roll [Application No.: 202110535348.0; Publication No.: CN 113102716A]. This rapid demoulding device for a centrifugally cast composite high-speed steel rolling roll includes a main frame, and also includes a floating plate that can move up and down relative to the main frame.

The driving mechanism drives the pushing mechanism to move up and down relative to the main frame. The main frame is provided with a limiting part for restricting the downward movement of the floating plate. Correspondingly, the floating plate is provided with a limiting mechanism. When the pushing mechanism moves upward, it drives the floating plate to move synchronously. When the floating plate moves to the position where the limiting mechanism cooperates with the limiting part of the main frame for limiting, a reset mechanism is provided between the pushing mechanism and the floating plate. It also includes a carrier plate arranged on the main frame, and an inner mold is movably arranged on the carrier plate.

[0004] Although the pushing mechanism disclosed in this patent improves the demoulding efficiency of the rolling roll, and the device is simple to manufacture, has a low cost, and saves the manufacturing cost, however, due to the adhesion between metals after condensation and forming, the mold and the rolling roll are tightly bonded together, and it is difficult to separate the mold and the rolling roll only by the pushing mechanism. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems existing in the prior art and propose a rapid demoulding device for a composite high-speed steel rolling roll. The technical problem to be solved by this utility model is: how to realize separating the mold and the rolling roll by knocking and vibrating first, and then pushing the rolling roll out of the mold for demoulding.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0008] The working principle of the utility model is as follows: through the driving mechanism, the moving block is driven to move, so that the knocking block on the moving block knocks the mould, separating the steel rolled in the mould from the mould, and then by moving the baffle and the pushing plate, the baffle and the pushing plate are respectively abutted against both ends of the mould, the cylinder is started, and the pushing block is used to push the mould, so that the roll is pushed out of the mould.

[0009] The mould includes an inner mould and an outer mould, one end of the inner mould protrudes from the outer mould, a circular groove is formed in the pushing ring, and the diameter of the circular groove is larger than the diameter of the outer mould.

[0010] With the above structure, since the diameter of the circular groove is larger than the diameter of the outer mould, the baffle abuts against the protruding part of the inner mould, and the pushing block sleeves the outer mould in the circular groove, realizing the convenient pushing of the steel rolled between the outer mould and the inner mould, so that the steel rolled is separated from the mould.

[0011] A sliding groove is formed in the mounting plate, a first motor is fixed on the mounting plate, a bidirectional threaded rod extending into the sliding groove is fixed at the output shaft end of the first motor, and both the baffle and the pushing plate are threadedly connected to the bidirectional threaded rod.

[0012] With the above structure, by installing the bidirectional threaded rod and starting the first motor to drive the bidirectional threaded rod to rotate, the baffle and the pushing block can move in opposite directions at the same time, so that the baffle and the pushing block can abut against the mould at the same time.

The moving block is reset by the elastic component, and the mould can be knocked repeatedly, realizing the separation of the mould from the roll by knocking vibration, and finally facilitating the pushing out of the roll from the mould.

[0015] The elastic component includes a plurality of moving grooves formed in the mounting plate. Springs are fixed in the moving grooves. The moving blocks are slidably connected to the moving grooves, and the other ends of the springs are fixedly connected to the moving blocks.

[0017] Compared with the prior art, the rapid demoulding device for the composite high-speed steel roll has the following advantages:

[0018] 1. Through the driving mechanism, the moving block is driven to move, so that the striking block on the moving block strikes the mold, separating the mold from the rolled steel in the mold.

[0025] AsFigures 1-3 As shown in the figure, this rapid demoulding device for composite high-speed steel rolls includes a mounting plate 1. An arc-shaped placement block 2 is fixed on the mounting plate 1. A mould 3 is placed on the placement block 2. Two first fixing plates 4 and two second fixing plates 5 are fixed on the mounting plate 1. A plurality of moving blocks 6 are slidably connected to the mounting plate 1. A knocking block 7 is fixed on the moving block 6, and the knocking block 7 is in contact with the mould. A driving mechanism is arranged between the moving block 6, the first fixing plate 4 and the second fixing plate 5. A baffle 8 and a push plate 9 are slidably connected to the mounting plate 1. A cylinder 10 is fixed on the push plate 9, and a push block 11 is fixed at the output shaft end of the cylinder 10.

[0026] Through the driving mechanism, the moving block 6 is driven to move, so that the knocking block 7 on the moving block 6 knocks the mould, separating the steel rolled in the mould 3 from the mould 3. Then, by moving the baffle 8 and the push plate 9, the baffle 8 and the push plate 9 are respectively abutted against both ends of the mould 3. The cylinder 10 is started, and the push block 11 pushes the mould 3, so that the roll is pushed out of the mould 3.

[0027] The mould 3 includes an inner mould and an outer mould. One end of the inner mould protrudes from the outer mould. A circular groove is formed in the push ring, and the diameter of the circular groove is larger than the diameter of the outer mould.

[0028] With the above structure, since the diameter of the circular groove is larger than the diameter of the outer mould, the baffle 8 abuts against the protruding part of the inner mould, and the push block 11 sleeves the outer mould in the circular groove, realizing convenient extrusion of the steel rolled between the outer mould and the inner mould, and separating the steel rolled from the mould.

[0029] A chute 12 is formed on the mounting plate 1. A first motor 13 is fixed on the mounting plate 1. A bidirectional threaded rod 14 extending into the chute 12 is fixed at the output shaft end of the first motor 13.

[0030] With the above structure, by installing the bidirectional threaded rod 14 and starting the first motor 13 to drive the bidirectional threaded rod 14 to rotate, the baffle 8 and the push block 11 move in opposite directions at the same time, so that the baffle 8 and the push block 11 abut against the mould 3 at the same time.

[0035] The working principle of the present utility model: Start the second motor 15, drive the first rotating rod 16 to rotate, the cylinder 18 on the first rotating rod 16 and the second rotating rod 17 rotates. When the cylinder 18 rotates to contact the fixed column 19, the cylinder 18 drives the moving block 6 on the fixed column 19 to move, so that the knocking block 7 on the moving block 6 knocks on the mold 3. The elastic force of the spring 21 can reset the moving block 6, and the mold 3 can be repeatedly knocked.
