Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum flat tube production, in particular to aluminum flat tube fixed-length cutting equipment with stable material transmission. Background Art

[0002] Aluminum flat tube is a long thin-walled tubular structure made of aluminum alloy material, with a flat cross-section (usually rectangular or approximately rectangular), light weight, high strength, good corrosion resistance and smooth surface. The existing aluminum flat tube cutting equipment with stable material transmission uses a feeding unit to clamp the material and then send it to the bottom of the cutting knife. The driving unit drives the aluminum flat tube to cut the appropriate position on the aluminum flat tube. However, in actual use, the feeding unit can only fix one side of the aluminum flat tube. When cutting, the aluminum flat tube may be offset due to the impact force, which will affect the cutting accuracy.

[0003] For example, the utility model with announcement number CN217832840U discloses a device for cutting aluminum flat tubes to length with stable material transmission, wherein the feeding component is composed of a plurality of detachably connected guide components, each of which comprises: a sliding block slidably connected to a slide groove, a receiving plate extending out of the slide groove being fixedly connected to the top of the sliding block; a support plate being fixedly connected to the top of the support plate; a limiting component is arranged on the top of the support plate; wherein the limiting component comprises two limiting devices symmetrically arranged on the top of the support plate and having a C-shaped cross section, each of which can be raised and lowered in the vertical direction; and the support plates in the plurality of guide components are connected to each other. Removable connection. In the technical solution of this patent, after the aluminum flat tube is placed on the feeding component, the spring limit unit limits the upper and lower positions of the aluminum flat tube, and then the feeding component moves the appropriate position on the aluminum flat tube to the bottom of the cutting knife, so that the cutting knife cuts the aluminum flat tube. In actual use, since the feeding unit can only fix one side of the aluminum flat tube and the limiting ability of the limiting unit is poor, the impact force of the cutting knife may cause the aluminum flat tube to shift when cutting to a fixed length, causing the position on the aluminum flat tube to move, which in turn affects the cutting accuracy.
