Description

Technical Field

[0001] This invention relates to the field of centrifugal casting equipment technology in the metallurgical casting industry, and mainly to a multi-specification horizontal centrifugal casting equipment with an integrated water-cooled bearing seat. Background Technology

[0002] Horizontal centrifugal casting equipment is a type of casting equipment that uses centrifugal force to form molten metal in a rotating mold. It is widely used in the production of pipe and sleeve castings. During operation, the mold is supported and driven to rotate by multiple sets of rollers. The operating state of the rollers directly affects the rotational accuracy of the mold and the quality of the casting.

[0003] The roller bearing seats in existing horizontal centrifugal casting equipment are mostly split and independent structures, meaning that each roller has an independent bearing seat at each end, and each bearing seat is machined and installed separately on the equipment base. This structural design has the following technical defects, affecting the operational stability of the equipment and the quality of the castings: 1) Large assembly error: Split bearing housings need to be installed and aligned one by one. During the assembly process, positioning and installation errors accumulate, making it difficult to guarantee the coaxiality and parallelism of each idler roller shaft. Even with precise manual alignment, errors cannot be completely eliminated, causing the idler rollers to tilt and bounce during operation. This, in turn, affects the rotational accuracy of the mold, ultimately leading to quality problems such as uneven wall thickness and roundness deviation in the casting.

[0004] 2) Severe component wear: Due to the accumulation of errors caused by the processing and installation of each bearing housing, the idler roller shaft and bearing will bear additional alternating loads. After long-term operation, the bearing is prone to wear and jamming, and the surface of the idler roller will also show uneven wear. This not only increases the consumption of spare parts and maintenance costs, but also leads to frequent equipment shutdowns and affects production efficiency.

[0005] 3) Poor operational stability: Vibrations generated during equipment operation can cause slight displacement of the bearing housing, further aggravating assembly deviations and forming a vicious cycle of "vibration-displacement-increased error". In severe cases, it can lead to mold detachment and pose a safety hazard.

[0006] Chinese invention patent application number 2020208044314 discloses a horizontal centrifugal casting machine, including a base, a motor, and a main shaft. The motor is fixed on the base, and its output end is connected to the main shaft for transmission. A front bearing seat and a rear bearing seat are fixed on the base. The bottom of the front bearing seat and the rear bearing seat are connected and are an integral structure. A front bearing shell is fixed on the front bearing seat, and a rear bearing shell is fixed on the rear bearing seat. The front bearing shell is rolled to the main shaft through an angular contact bearing and a rolling bearing, and the rear bearing shell is rolled to the main shaft through a self-aligning roller bearing. A cooling water interface is opened on the top of the front bearing seat, and a cooling water channel is opened inside around the front bearing shell. The cooling water channel is connected to the cooling water interface pipeline, and a water cooling system is connected to the cooling water interface. In the prior art, horizontal centrifugal casting equipment with split bearing seats generally suffers from technical defects such as large assembly errors, easy wear of parts, poor operating stability, low assembly efficiency, and high maintenance difficulty, which are not conducive to improving the operating stability of the equipment and the precision of the castings. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1) Eliminate assembly errors and improve casting accuracy: This invention integrates the bearing mounting position of the idler roller assembly into an integrated water-cooled bearing seat.

The rotation accuracy of the centrifugal casting is greatly improved, effectively solving quality problems such as uneven casting wall thickness and roundness deviation. 2) Reduce component wear and extend equipment service life: Because the position accuracy of each idler roller is precisely controlled, the idler roller, bearing and transmission components are subjected to uniform force and there is no additional alternating load, which effectively avoids problems such as bearing jamming and uneven wear of idler rollers, and greatly reduces spare parts consumption and maintenance costs. 3) Improve operational stability and reduce safety hazards: The integrated water-cooled bearing housing structure, combined with internal reinforcing ribs, improves overall rigidity; the matching installation of the positioning boss at the bottom of the bearing housing and the groove in the base reduces the risk of displacement caused by bolt loosening due to vibration during equipment operation, effectively avoiding the vicious cycle of "vibration-displacement-increased error"; thus improving the safety and stability of equipment operation. 4) Improve assembly efficiency and reduce labor costs: The integrated water-cooled bearing housing allows for the pre-assembly of the active and passive side roller assemblies, which are then hoisted onto the base as a whole. The positioning boss and groove mating structure enables quick positioning and bolt fixing, eliminating the need to align each bearing housing individually and significantly improving assembly efficiency. 5) Wide range of applications and strong practicality: The present invention can adjust the spacing between the main and secondary roller assemblies according to production needs, and adapt to the production of ring and sleeve castings of different specifications.
