Description

Technical Field

[0001] The utility model relates to the technical field of metal material processing, in particular to a feeding device that prevents aluminum alloy profiles from being scratched when being sawed by multiple saws at the same time. Background Art

[0002] Aluminum profiles, tubes, and rods are typically formed through hot extrusion, utilizing the cavity-forming action of a mold. They are characterized by their continuous nature. Freshly extruded aluminum profiles, tubes, and rods are typically quite long and are continuously conveyed through the roller conveyor at the extrusion exit until a cast rod is completely extruded, at which point they are cut. A cooling bed belt is connected to one side of the roller conveyor at the extrusion exit, allowing for transverse transport of the cut aluminum and serving as a cooling staging area.

[0003] In actual production, aluminum profiles are not transferred individually during the sawing process on the exit roller conveyor and cooling bed belt conveyor. Instead, they are transferred horizontally in groups. This is especially true when the cross-sectional dimensions of aluminum profiles or tubes and bars are small, and multiple porous dies extrude several aluminum profiles of the same size simultaneously. In this case, as many as a dozen aluminum profiles may be transferred horizontally simultaneously on the roller conveyor and cooling bed. Excessive aluminum profiles are too close together to separate, causing collisions and compression, resulting in surface damage or deformation, resulting in scrap, reducing yield, and increasing production costs. Summary of the Invention

[0004] The purpose of the utility model is to provide a feeding device that prevents aluminum alloy profiles from being scratched when multiple saws are cut at the same time. The device uses a roller with a plurality of separator rings evenly distributed to transmit the extruded small-section aluminum profiles at intervals, effectively preventing the aluminum profiles from being squeezed, rubbed and collided due to being too close to each other, thereby improving the surface quality of the aluminum profiles and reducing the scrap rate.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0006] A feeding device for preventing scratches on the surface of aluminum alloy profiles caused by simultaneous sawing of multiple pieces. The roller shaft of the separation roller has shaft extensions at both ends, which are connected to the lifting mechanism. The circumferential surface of the roller shaft is covered with high-temperature resistant felt. Several separation rings are evenly distributed along the length of the roller shaft, and the interval area between the separation rings is the transmission path for the aluminum material.

[0007] The separator roller can replace the ordinary cylindrical roller on the feed roller of the existing extrusion cooling bed. The two ends of the roller are usually hinged to the end of the connecting rod driven by the cylinder, and the lifting effect of the cylinder is used to achieve the simultaneous lifting and lowering of the roller group; the high-temperature felt is usually a Kevlar heat-resistant layer, which can not only ensure that the aluminum surface is not scratched, but also prevent the aluminum from damaging the roller.

[0008] The separator ring is provided with a threaded through hole, and the roller shaft is provided with a threaded blind hole at a matching position. The threaded through hole and the threaded blind hole are passed through the set screws for fixing. At the same time, the high temperature felt is also pre-punched to facilitate the passage of the set screws.

[0009] The separator ring can be disassembled and installed at will with respect to the roller, which increases the flexibility of the separator ring setting. When the cross-section of the aluminum material is slightly larger, several separator rings are evenly removed to increase the spacing between them to meet the position requirements; when the cross-section of the aluminum material is slightly smaller, it also means that the number of aluminum materials extruded in the same mold is greater, so the number of separator rings is increased to meet the number of aluminum materials required.

[0010] Several transverse belts are evenly spaced between the adjacent separator rollers. When the separator rollers are loaded with aluminum materials and driven down by the cylinders, the aluminum materials are supported by the transverse belts, which transport them horizontally, moving the aluminum materials evenly and smoothly without contact.

[0011] The edges of the separation rings are chamfered or rounded to prevent damage to the surface of the aluminum material and to facilitate the aluminum material to be confined in the area between the separation rings.

[0012] The separator ring is made of high-temperature nylon material, such as a separator ring made of Kevlar material.

[0013] Utility model advantages:

[0014] 1. The utility model utilizes a roller with several spacer rings evenly distributed to transmit the extruded small-section aluminum materials at intervals, effectively preventing the aluminum materials from being squeezed, rubbed and collided due to being too close to each other, thereby improving the surface quality of the aluminum materials and reducing the scrap rate.

[0015] 2. The utility model is flexible in setting and can be dismantled or installed on the roller at will. It can be adjusted according to the size of the aluminum cross section and has high flexibility.

[0016] 3. The utility model can be interchangeable with the traditional cylindrical roller on the existing extrusion cooling bed, with low replacement cost and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
