Description

Technical Field

[0001] This utility model belongs to the field of seamless steel pipe technology, and in particular relates to a sizing device. Background Technology

[0002] The sizing mill is an important piece of equipment in the rolling of seamless tubes. It has the functions of reducing the diameter, improving the dimensional accuracy of seamless tubes, enhancing mechanical properties, and optimizing the internal structure of seamless tubes. It is an important process in the production of seamless steel tubes.

[0003] The shortcomings of typical sizing mill frames and transmission devices are as follows: Generally, the sizing mill main unit needs to ensure geometric accuracy during assembly, especially when installing the slide plate, which is usually CNC machined as a whole to guarantee dimensional and positional tolerances, ensuring the sizing mill frame meets process requirements during use. After a period of use, the slide plate in contact with the sizing mill frame will experience a certain amount of wear. Once the slide plate no longer meets the requirements, it needs to be replaced. At this point, it is impossible to machine the entire frame to guarantee dimensional and positional tolerances. The cumulative errors caused by manual installation are extremely difficult to guarantee process requirements, and replacement is extremely cumbersome.

[0004] The automatic coupling of a sizing machine is usually directly mounted on the output shaft of the reducer. However, if the coupling is large, its weight is also significant, which can affect the bearing at the output end of the reducer. As wear increases, the coupling may sag, affecting normal operation. Replacement is also difficult due to space constraints. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a sizing device that facilitates quick replacement of the main plate and delays the reduction in service life of the coupling caused by its own weight.

[0006] In view of this, the present invention provides a sizing device, including a base, a side wall fixedly connected to the top edge of the base, a top cover fixedly connected to the top of the side wall, a column provided at the connection between the base and the top cover, a mother plate fixedly connected to the outer wall of both the base and the top cover, a slot provided on the outer wall of the mother plate, a locking post embedded in the slot, a sliding plate welded to one end of the locking post, a limiting plate embedded in the outer wall of the sliding plate, a sizing arch welded to the outer wall of the limiting plate, a hydraulic cylinder fixedly connected to the top of the top cover, a pressing seat installed at the output end of the hydraulic cylinder that fits against the top of the sizing arch, a sizing roller bearing connected to the inner wall of the sizing arch, a connecting gear sleeve fixedly connected to the outer wall of the sizing roller, an involute spline installed on the inner wall of the connecting gear sleeve, a coupling bearing connected to one end of the involute spline, and a reducer output shaft bearing connected to the outer wall of the coupling.

[0007] Based on the above structure, the sizing arch of this utility model can quickly and effectively replace the slide plate without disassembling and processing the whole machine. This can ensure the installation accuracy of the whole machine, make the whole production line run smoothly, and effectively avoid the problems of reducer oil leakage, bearing damage, accelerated wear of coupling and large clearance caused by the weight of the coupling, as well as the problems of reduced service life and difficult replacement.

[0008] Preferably, two sets of side walls are provided, and the two sets of side walls are parallel to the sizing archway. In this embodiment, stable support operation is achieved for the base and the top cover, and misalignment of the base and the top cover is avoided.

[0010] Preferably, the slot is in the shape of an inverted "L". The slide plate forms an engaging structure with the mother plate through the slot and the locking post. In this embodiment, it is convenient for the slide plate to engage with the slot through the locking post and install the slide plate on the mother plate.

[0011] Preferably, the cross-section of the sliding plate is U-shaped, and two sets of sliding plates are provided. The sizing arch forms a positioning structure between the sliding plate, the pressing seat, and the upper cover. In this embodiment, by providing a sliding plate with a U-shaped cross-section, it is beneficial for the sizing arch to engage with the sliding plate through the limiting plate, thereby realizing a rapid positioning operation of the sizing arch.

[0012] Preferably, the slide plate is made of ductile iron, which greatly reduces the wear and tear on the mother plate in this embodiment.

[0013] Preferably, the sizing rollers are provided in three sets, and the three sets of sizing rollers are distributed in a circle at equal angles about the central axis of the sizing arch. In this embodiment, by providing three sets of sizing rollers, it is convenient to perform sizing operation on the seamless steel pipe and avoid deformation of the seamless steel pipe.

[0014] The beneficial effects of this utility model are: This sizing equipment, by setting a sliding plate, allows for quick and efficient replacement of the sizing arch without the need for overall disassembly and processing. This ensures the installation accuracy of the entire machine, enabling the smooth operation of the entire production line. It also effectively avoids problems such as reducer oil leakage, bearing damage, accelerated wear of the coupling, and reduced service life due to large gaps caused by the weight of the coupling, as well as difficulties in replacement.
