Abstract
The utility model discloses a combined roll for ring rolling mill and a ring rolling mill; the combined roll consists of at least two sections; each section is axially provided with an inner circle with identical inner diameter; the inner circle is provided with a positioning structure; the ring rolling mill is provided with the combined roll; according to the utility model, the original integral roll is designed into at least two sections in a manner of sectional combination; the total size of some sections equals the total size of the original integer roll; the structure and material of two sections can be independently selected; each section can be independently designed based on own requirement; any section can be replaced according to the abrasion condition and the requirement for rolling different types of rings; the combined roll greatly facilitates the utilization of the ring rolling mill and saves the using cost.
Description
Technical field
The utility model relates to the aluminium alloy process equipment, exactly is machine for rolling ring with composite (back-up) roll and machine for rolling ring.
Background technology
Roll is the strength member on the machine for rolling ring, and the pressure that produces when utilizing a pair of or one group of roll rolling rolls the stone roller shape, is the important consumable part of decision milling train efficient and mill bar quality.Original roll is all-in-one-piece, and self cost height is then wanted integral replacing in the time of need changing as serious wear, with 5 meters machine for rolling ring φ 900 king rollers is example, whenever changes a roll and needs 180,000 yuan approximately, and volume and weight is all very big, be not easy to change, rolling different type ring will be used different rolls, and cost is higher.
The utility model content
At the problems referred to above that prior art exists, it is a kind of relatively independent and replace conveniently that the purpose of this utility model is to provide, and the machine for rolling ring that can save the material cost of machine for rolling ring king roller and processing charges greatly is with composite (back-up) roll and machine for rolling ring.
The utility model adopts following technical scheme:
A kind of machine for rolling ring composite (back-up) roll, this roll constitutes by at least two sections, and each section axially is provided with the interior circle of same inner diameter respectively, and interior circle is provided with location structure.
Preferably, described each section is respectively straight roller or forming roll.
Preferably, described each section constitutes forming roll.
Preferably, described location structure be parallel to roll mandrel to keyway.
A kind of machine for rolling ring comprises frame and rack-mounted back shaft, and above-mentioned arbitrary composite (back-up) roll is installed on the described back shaft.
The utility model becomes at least two sections to former monoblock type Roller Design with the mode of segmentation combination, several sections overall size equals former all-in-one-piece overall size, two sections structure and material can relatively independently be selected, each section can carry out independent design according to needs separately, and wherein any one section can be replaced according to the needs of wear condition and rolling different shaped ring, greatly facilitate the use of machine for rolling ring, also saved use cost.
Description of drawings
Fig. 1 is the structural representation of a segment type roller in the utility model;
Fig. 2 is the vertical view of forming roll shown in Figure 1;
Fig. 3 is the structural representation of one section straight rod in the utility model.
The specific embodiment
Core of the present utility model provides a kind of relatively independent and replace conveniently, and the machine for rolling ring that can save the material cost of machine for rolling ring king roller and processing charges greatly is with composite (back-up) roll and machine for rolling ring.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Machine for rolling ring frame in this specific embodiment is provided with the back shaft (figure does not indicate) that is used for installing roll, and composite (back-up) roll is installed on the described back shaft.
Please refer to Fig. 1, Fig. 2, Fig. 3, composite (back-up) roll by at least two sections independently roll 1 constitute, each section axially is provided with the interior circle 2 of same inner diameter respectively, described in the circle be provided be parallel to roll mandrel to keyway 3, described back shaft passes the interior circle 2 of each section, and the positioning key on passing through axially is with described keyway 3 fixed-site, thereby each section roll and back shaft are realized radial location, described frame with the strict restriction of the axial location of described composite (back-up) roll, makes stable being installed on the described machine for rolling ring of described composite (back-up) roll again.
One section in the composite (back-up) roll is forming roll, as shown in Fig. 1,2, has die cavity 11 on the excircle, another section is straight roller, as shown in Figure 3, can carry out independent assortment as required, mode with the segmentation combination is synthesized an integral body to the multistage roll stacks, each section overall size equals the overall size of existing monoblock type roll, the structure of each section, material and Technology for Heating Processing can relatively independently be selected, for example respectively materials processing such as carbon steel, steel alloy and, and can carry out independent design according to the annular needs of the rolling type of each section, perhaps each section constitutes a forming roll mutually.And wherein any one section can be replaced according to the needs of wear condition and rolling different shaped ring, greatly facilitates the use of machine for rolling ring, can make the material cost of king roller and processing charges reduce more than 1/3.
More than machine for rolling ring provided by the utility model is described in detail with composite (back-up) roll and machine for rolling ring.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
Claims (5)
