Description

Technical Field

[0001] The utility model relates to the technical field of coil production, and particularly relates to a sleeve for rolling plates. Background Art

[0002] At present, when producing coil products with a thickness of ≥1 mm, since the head thickness of the plate material is relatively thick, after curling layer by layer, the thick head will produce bottoming folds on the surface of the plate layer pressed on it. The thicker the single-layer coil, the more obvious the folds.

[0003] To mitigate the effect of folds, in the prior art, flexible or elastic fillers with large deformations, such as foam cotton, are usually inserted between the reel and the coil to weaken the folds. However, this method can only reduce the length of the coil with folds by 10%-20%. Therefore, in the patent documents with application numbers CN200710061892.6 and CN201810809312.5, to further improve the effect of mitigating folds, a filler with a transition (elastic gasket / sleeve attachment) is mentioned. The filler is pre-installed on the sleeve, and then the plate rolling work is carried out to reduce the degree of sudden change in curvature during the subsequent plate rolling process.

[0004] However, the above methods for mitigating the effect of folds still have certain problems: when the thickness of the produced plate changes or the size of the used reel changes, it is necessary to re-design the size of the filler (elastic gasket / sleeve attachment) to adapt to the above changes. In the actual production process, the design, mold opening, manufacturing and other links of the filler here all require a large amount of manpower and material resources, reducing the production rate of the coil and increasing the production cost of the coil. Summary of the Utility Model

[0005] The utility model aims at the problems in the prior art and provides a sleeve capable of rolling plates with various different thicknesses, solving the problems of reducing the production rate of coils and increasing the production cost of coils caused by designing corresponding adapters for different thicknesses and different reel sizes in the prior art.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A sleeve for sheet metal rolling includes a main body, wherein the main body is provided with at least two schematic grooves in an axial direction around a circumferential direction, wherein the schematic grooves are L-shaped and include a first slot and a second slot, wherein the first slot is provided along the radial direction of the main body, and the second slot is located inside the main body, and the first slots of different schematic grooves have different heights. By pre-opening a plurality of schematic grooves of different sizes on the sleeve, when performing sheet metal rolling, the staff selects the corresponding schematic groove according to the thickness of the sheet metal, removes the sleeve body portion above the selected schematic groove, and then places the sheet metal head in the corresponding schematic groove after removing the portion of the main body, and performs the sheet metal rolling process. There is no need to design corresponding fillers for sheets of different thicknesses to perform the filling process between the sheet metal and the sleeve, thereby solving the problem of low coil production rate caused by design and production, and avoiding the problem of high coil production cost caused by design, production and filler costs.

[0008] Preferably, the body is made of a paper sleeve. By selecting the paper sleeve, the production cost and weight of the sleeve can be reduced while ensuring the force, which is convenient for reducing the production cost and transportation cost of the coil.

[0009] Preferably, the guide groove is opened through the main body in the axial direction. By opening the guide groove through, after determining the guide groove, the staff can directly use tools to pry open the paper body above the guide groove until it breaks, and then use an angle grinder or trimmer to smooth the broken part, avoiding the problem of wasting time caused by manual grooving on site.

[0010] Preferably, the plurality of signal grooves are evenly distributed along the circumference of the body. When the plurality of signal grooves are evenly distributed, after the body above one of the signal grooves is removed, the body at the remaining signal grooves has a slightly lower support strength for the coil than the remaining parts due to the presence of the signal grooves. The evenly distributed signal grooves can disperse the parts with slightly lower support strength, thus avoiding the problem of uneven dispersion of the sleeve's support effect on the coil.

[0011] Preferably, four signal slots are provided.

[0012] Preferably, the body is further provided with identification members, the number of which is the same as the number of the indicator slots and corresponding to each other. The staff can use the identification members to determine the height values of the first slots in different indicator slots, so as to quickly determine the indicator slot corresponding to the sheet to be rolled, while avoiding the problem of staff making mistakes in selecting the first slot height due to manual measurement or visual inspection.

[0013] As can be seen from the above technical solutions, the advantages of the present utility model are as follows: By pre-opening a plurality of indicating grooves with different sizes on the sleeve, during the plate rolling work, the staff selects the corresponding indicating groove according to the thickness of the plate, removes the part of the sleeve body above the selected indicating groove, and then places the head of the plate material in the corresponding indicating groove after removing the part of the body. The plate rolling process is carried out without designing corresponding fillers for plates with different thicknesses to fill the space between the plate and the sleeve, solving the problem of low production rate of the coil caused by design and production, and avoiding the problem of high production cost of the coil brought by design, production and filler cost. By using the selected paper sleeve, the production cost and weight of the sleeve can be reduced on the premise of ensuring force, which is convenient for reducing the production cost and transportation cost of the coil. By penetrating the indicating groove, after determining the indicating groove, the staff can directly use tools to pry the paper body above the indicating groove until it breaks, and then use a angle grinder or a trimming machine to trim the broken part to a smooth state, avoiding the problem of wasting time caused by on-site manual grooving. When a plurality of indicating grooves are evenly distributed, after removing the body above one of the indicating grooves, the support strength of the body at the remaining indicating grooves for the coil is slightly lower than that of the other parts due to the existence of the indicating grooves. The evenly distributed indicating grooves can disperse the slightly lower support strength parts, avoiding the problem of uneven dispersion of the support effect of the sleeve on the coil. The staff can use the identification piece to mark the height value of the first grooving in different indicating grooves, so as to quickly determine the indicating groove corresponding to the plate to be rolled, and at the same time avoid the problem of selection errors caused by manual measurement or visual inspection of the height of the first grooving by the staff.

[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0021] Example:

[0022] like Figures 1-4 As shown, a sleeve for sheet rolling includes a body 1. The body 1 is provided with at least two schematic grooves 2 in the circumferential direction along the axial length, and in this embodiment, four schematic grooves 2 are provided. The four schematic grooves 2 are evenly distributed on the body 1. The schematic grooves 2 are L-shaped. The schematic grooves 2 include a first slot 3 and a second slot 4. The first slot 3 is provided along the radial direction of the body 1, and the second slot 4 is located inside the body 1. The first slots 3 of different schematic grooves 2 have different heights. In this way, by pre-opening a plurality of schematic grooves 2 of different sizes on the sleeve, when performing sheet rolling work, the staff selects the corresponding schematic groove 2 according to the thickness of the sheet, removes the portion of the sleeve body 1 above the selected schematic groove 2, and then rolls the sheet. The material head is placed in the corresponding schematic groove 2 after removing part of the main body 1, and the rolling process of the plate is carried out. There is no need to design corresponding fillers for plates of different thicknesses to carry out the filling process between the plate and the sleeve, which solves the problem of low coil production rate reduced by design and production, and avoids the problem of high coil production cost caused by design, production and filler costs. When several schematic grooves 2 are evenly distributed, after the main body 1 above one of the schematic grooves 2 is removed, the main body 1 at the remaining schematic grooves 2 has a slightly lower support strength for the coil than the rest of the parts due to the existence of the schematic grooves 2. The evenly distributed schematic grooves 2 can disperse the parts with slightly lower support strength, avoiding the problem of uneven dispersion of the sleeve's support effect on the coil.

[0023] In this embodiment, the main body 1 is made of a paper sleeve, and the schematic groove 2 is opened through the main body 1 in the axial direction. With such an arrangement, the selected paper sleeve can reduce the production cost and weight of the sleeve while ensuring the force, which is convenient for reducing the production cost and transportation cost of the coil. By opening the schematic groove 2 through, after determining the schematic groove 2, the staff can directly use tools to pry open the paper body 1 above the schematic groove 2 until it breaks, and then use an angle grinder or trimmer to smooth the broken part, avoiding the problem of wasting time caused by manual grooving on site.

[0024] In this embodiment, an identification member 5 is further provided on the main body 1. The number of the identification members 5 is the same as that of the schematic grooves 2 and they are arranged in one-to-one correspondence. The identification member 5 can be a sticker with different numerical values, a pattern with different shapes, or other components that are convenient for the staff to distinguish and judge. With such a setting, the staff can use the identification member 5 to obtain the height values of the first grooves 3 in different schematic grooves 2, so as to quickly determine the schematic groove 2 corresponding to the plate to be rolled, and at the same time avoid the problem of selection errors caused by the staff manually measuring or visually observing the height of the first groove 3.

[0025] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
