Description

Technical field:

[0001] The utility model relates to the technical field of metal processing equipment, and more specifically to an aluminum material flattening device. Background technology:

[0002] In the existing aluminum strip manufacturing process, it is continuously cold rolled as needed to meet the processing standards. However, during the processing, when the aluminum strip is cold rolled, there will definitely be substandard parts at the head end and the tail end of a coil. This part needs to be cut in the subsequent processing. The cut aluminum strip is in the shape of a strip, which occupies a large space and needs to be flattened to reduce the space occupancy. In the existing flattening device, the clamping plate is generally pushed or retracted by the push rod of the oil cylinder to achieve the lifting and lowering of the clamping plate. The clamping plate is generally fixed to the push rods of at least two oil cylinders for lifting and lowering. Since the lifting distance of the clamping plate is large and there is no other guiding structure, a small offset will occur when the clamping plate is lifted and lowered, resulting in a small misalignment between it and the bottom clamping horizontal support plate. Over time, the clamping plate will eventually be offset too much and get stuck with the side walls of the frame on both sides of the flattening device, affecting normal use.

[0003] At the same time, the top surface of the existing clamping plate is generally welded with multiple reinforcing ribs to improve its strength, and a connecting plate is fixed on the corresponding reinforcing ribs of the clamping plate, and the connecting plate is directly fixed to the bottom of the push rod of the clamping cylinder. When the bottom surface of the clamping plate is uneven or deformed and needs to be replaced, the entire clamping plate can only be disassembled and replaced, which is heavy and troublesome to replace. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an aluminum material flattening device, wherein the front and rear left and right parts of the pressing frame are fixedly connected to side guide plates by fixing bolts, so that the lifting and lowering of the pressing frame can be guided to ensure its normal lifting and lowering. At the same time, a replaceable pressing plate is installed at the bottom of the pressing frame, and the weight of the pressing plate is lighter than that of the pressing frame, so it is relatively convenient to replace.
