Description

Technical Field

[0001] The present invention relates to the technical field of roll casting molding, and specifically relates to a casting and molding device for cast iron rolls. Background Art

[0002] A horizontal centrifugal casting machine is a centrifugal casting equipment in which the mold rotates around a horizontal axis. Liquid metal is poured into the rotating mold. The mold rotates at a high speed driven by the centrifugal casting machine. The liquid metal fills the mold under the action of centrifugal force and solidifies into a casting. Driven by centrifugal force, metal crystallization proceeds sequentially from the mold wall to the inner surface of the casting, with a certain directional cooling crystallization, which makes some impurities such as slag, gas, and inclusions concentrate on the inner surface layer of the casting. At the same time, the structure of other parts of the casting is also fine. The roll can be processed by a centrifugal casting machine. Centrifugal casting uses a high-speed rotating mold to make the molten metal fill the cavity under the action of centrifugal force, form a dense outer layer, and discharge gas and impurities, and finally obtain a roll with uniform structure and excellent mechanical properties.

[0003] When the above device is used, it does not have a structure for adapting the transmission of the centrifugal casting machine to multiple sizes of molds, auxiliary limiting of the mold, and quickly assisting in stopping when out of control. When the existing horizontal centrifugal casting machine is used, the distance between the two sets of support wheels for driving the mold is mostly a fixed length, making it difficult to adapt to different sizes of molds for centrifugal casting. Moreover, the mold lacks limitation during the rotation casting operation on the support wheels. Only relying on the left and right two sets of support wheels to limit the mold has a poor effect. And if the mold shakes or is about to get out of control during rotation, the mold cannot be quickly stopped. Based on the existing technical deficiencies, the present invention designs a casting and molding device for cast iron rolls. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The casting and forming device for a cast iron roll controls the contraction of both ends of a double-axis telescopic rod through an external control device to pull the movable push plate inward. The moving movable push plate uses the support push plate to pull the clamping block to slide and contract inside the telescopic groove, so that the outer side of the clamping block does not contact the side groove for clamping and fixing. At this time, the motor is started to drive the screw rod to rotate clockwise or counterclockwise. The rotating screw rod drives the sliding seat to rotate left or right inside the adjustment groove through the thread groove. Since one set of support wheels is fixedly connected to the upper surface of the sliding seat by a fixed seat, when the sliding seat moves and adjusts left and right, one set of support wheels will also move and adjust accordingly until the distance between the two sets of support wheels matches the size of the mold to be placed. Finally, control the two ends of the double-axis telescopic rod to extend, use the movable push plate to push the support push plate to expand and push the two clamping blocks to expand outward to contact the inner wall of the side groove to lock the positions of the sliding seat and the limit seat. This device is convenient for adjusting the distance between the two sets of support wheels according to the size of the mold.

[0016] 2. The casting and forming device for a cast iron roll, after the distance between the two sets of support wheels is adjusted by the support mechanism to be completed and the mold is placed on the support wheels and aligned with the limit rail, the external control device controls the second telescopic cylinder to extend, and uses the fourth rotating rod and the rotating sleeve to push the limit arm to rotate under the limit of the second rotating rod, so that the end of the limit arm connected with the third rotating rod and the limit wheel moves downward until the limit wheel contacts and limits the surface of the mold and the limit rail. This device is convenient for auxiliary limiting of molds of different sizes.

[0017] 3. The casting and forming device for a cast iron roll, after the drive of the support wheels is quickly stopped after the mold gets out of control and then the first telescopic cylinder is started to control its contraction, the contracting first telescopic cylinder pulls the toothed clamping plate to rotate and snap into the inside of the third rotating rod under the limit of the fixed rod, so that the third rotating rod and the limit wheel quickly stop rotating and friction on the surface of the mold to assist in stopping it. At the same time, the second telescopic cylinder also extends a certain distance to push the limit arm to provide a downward pressure for the limit wheel. This device is convenient for quickly stopping the rotating out-of-control mold. Description of the Drawings

[0029] Working principle: When a casting device for a cast iron roll is in use, in the initial state, first, there are two sets of fixed seats 103 arranged on the base 1. A first rotating rod 105 and a support wheel 106 are rotatably connected to the support plate 104 mounted on the fixed seat 103 to provide rotational support for the mold 2. A transmission wheel 107 is arranged on one side of one of the support wheels 106 to facilitate connection with a transmission belt and a transmission machine to drive the support wheel 106 to rotate and drive the mold 2 to rotate for centrifugal casting. A slider 302 is slidably connected in a slideway 3 arranged on one side of the base 1. A lower pulley 303 and an upper pulley 304 are respectively rotatably connected to the upper and lower sides of the slider 302. The outer end of the slider 302 is connected with a support arm 305. The outer end of the support arm 305 is connected to and supported by a feeding hopper 308 and a feeding pipe 309 through a support column 306 to facilitate feeding the feeding pipe 309 into the mold 2 for feeding treatment. A limiting arm 403 rotatably arranged above the base 1 is rotatably connected to the support frame 401 through a second rotating rod 402. A third rotating rod 404 rotatably connected to the front section of the limiting arm 403 and a limiting wheel 405 are fixedly connected with a stop gear 406. The stop gear 406 can be engaged with a toothed clamping plate 409 rotatably connected to the inner side of the limiting arm 403 on a fixed rod 408, so as to facilitate using the limiting wheel 405 to assist in limiting the rotation of the mold 2 and at the same time stop the limiting wheel 405 from rotating to quickly stop the mold 2. At the same time, a sliding seat 505 and a limiting seat 506 are slidably connected in an adjustment groove 501 and a side groove 502 opened on the base 1. Both ends of a double-shaft telescopic rod 512 arranged in the sliding seat 505 are respectively connected with a movable push plate 513 and a support push plate 514. The outer end of the support push plate 514 is connected with a clamping block 510 sliding in a telescopic groove 508 through a rotating groove 511. The sliding seat 505 is also connected with a motor 503 and a lead screw 504 arranged in the base 1 to facilitate adjusting the position of the sliding seat 505 and locking it, and further adjusting the positions of one of the fixed seats 103, the support plate 104, the first rotating rod 105 and the support wheel 106 connected above the sliding seat 505; When it is necessary to adjust the distance between the two sets of support wheels 106 according to the size of the mold 2, first, the external control device controls the two ends of the double-axis telescopic rod 512 to contract and pull the movable push plate 513 to move inward. The moving movable push plate 513 uses the support push plate 514 to pull the clamping block 510 to slide and contract inside the telescopic groove 508, so that the outer side surface of the clamping block 510 does not contact and clamp with the side groove 502. At this time, the motor 503 is started to drive the lead screw 504 to rotate clockwise or counterclockwise. The rotating lead screw 504 drives the slide block 505 to rotate left or right inside the adjustment groove 501 through the thread groove 507. Since one set of support wheels 106 is fixedly connected to the upper surface of the slide block 505 by the fixed seat 103, when the slide block 505 moves left and right for adjustment, one set of support wheels 106 will also move and adjust accordingly until the distance between the two sets of support wheels 106 matches the size of the mold 2 to be placed. Finally, control the two ends of the double-axis telescopic rod 512 to extend, use the movable push plate 513 to push the support push plate 514 to expand and push the two clamping blocks 510 to expand outward to contact the inner wall of the side groove 502 to lock the positions of the slide block 505 and the limit seat 506. This device is convenient for adjusting the distance between the two sets of support wheels 106 according to the size of the mold 2.

[0030] When it is necessary to assist in limiting molds 2 of different sizes, first, after the support mechanism 5 completes the adjustment of the distance between the two sets of support wheels 106 and places the mold 2 on the support wheels 106 and aligns it with the limit rail 203, the external control device controls the second telescopic cylinder 413 to extend and uses the fourth rotating rod 411 and the rotating sleeve 414 to push the limiting arm 403 to rotate under the limitation of the second rotating rod 402, so that the end of the limiting arm 403 connected with the third rotating rod 404 and the limiting wheel 405 moves downward until the limiting wheel 405 contacts and limits the surface of the mold 2 and the limit rail 203. This device is convenient for assisting in limiting molds 2 of different sizes.

[0031] When it is necessary to quickly stop the out-of-control rotating mold 2, first, quickly stop driving the support wheels 106 after the mold 2 gets out of control, and then start the first telescopic cylinder 410 to control it to contract. The contracting first telescopic cylinder 410 pulls the toothed clamping plate 409 to rotate and snap into the inside of the third rotating rod 404 under the limitation of the fixed rod 408, so that the third rotating rod 404 and the limiting wheel 405 quickly stop rotating and friction on the surface of the mold 2 to assist in stopping it. At the same time, the second telescopic cylinder 413 also extends a certain distance to push the limiting arm 403 to provide a downward pressure for the limiting wheel 405. This device is convenient for quickly stopping the out-of-control rotating mold 2.
