Double-drive four-roller synchronously adjustable semi-solid metal powder rolling mill

Abstract

The invention provides a double-drive four-roller synchronously adjustable semi-solid metal powder rolling mill, which includes a frame structure, a frame, a hopper, a horizontal roll system, a vertical roll system, and a roll translation module; wherein, the hopper is located directly above the rolling mill, and two The side support plate is provided with a chute that can be used to adjust the height of the relative rollers. A total of 4 rollers in the horizontal roller system and the vertical roller system are arranged in the same plane. Rotation, one horizontal roll and one vertical roll in the roll system are respectively designed with a translation system, which is used to realize the translation of the corresponding roll and then adjust the length and width of the seam, and finally realize the control of the thickness of the plate and strip. The rack is located directly below And it is set together with the rack end cover. The rolling mill designed by this invention can produce metal plates and strips with adjustable width and thickness, neat strip edges, and high density. It has the advantages of high efficiency, low energy consumption, easy operation, and a large processing size range.

Description

technical field [0001] The invention relates to the field of semi-solid metal powder preparation, in particular to a double-drive four-roller synchronously adjustable semi-solid metal powder rolling mill. Background technique [0002] Semi-solid powder continuous forming technology is widely used due to its advantages of high efficiency, low energy consumption, easy operation, and large size range of processed products, mainly including rheological forming and thixoforming. Among various powder forming technologies, semi-solid powder rolling forming technology can prepare plates, strips, etc. that cannot be produced or are difficult to produce by other forming technologies. , Rolled products are isotropic and have a high yield, so semi-solid powder rolling forming technology has become the most important technical means in continuous forming technology, and has been widely used in chemical, energy, transportation, environmental protection and other industries. The semi-soli...

Problems solved by technology

At present, the existing equipment for semi-solid metal powder rolling still adopts the two-roll structure of the traditional rolling mill, or the structure of two support rolls and two work rolls arranged horizontally. First of all, it cannot fully adapt to this new forming Second, the material supply is inconvenient, the width direction of the plate and strip produced by complex equipment is often uncontrollable, and the strip changes are messy and do not meet the production requirements, and need to be trimmed in the later stage, especially the density cannot meet the higher requirements

[0003] On the other hand, the traditional rolling mill is two-roll or four-roll, and the axes of the rolls are arranged in parallel in a plane, and there are only two work rolls. Therefore, this kind of rolling mill can only control the thickness of the strip, but cannot control the thickness of the strip. The size of the width direction of the strip, and the width direction does not provide rolling force, so that the edge of the produced strip is messy and uneven, and the density is extremely low. It is necessary to trim the edge in the later stage, which reduces the yield of the powder strip. Rate

Another problem with this traditional rolling mill is that it is inconvenient to feed materials. Manual feeding is often used, and there is also a funnel feeding. However, because the rolling technology has certain requirements for the rolling angle, the feeding method of this rolling mill is limited. Production of plate and strip in multiple thicknesses
