Description

Auxiliary clamp for extrusion of aluminum profile

Technical Field

The utility model relates to the technical field of aluminum profile processing equipment, in particular to an auxiliary clamp for aluminum profile extrusion.

Background

As the shape section of the extruded aluminum profile becomes more and more complex, many asymmetric or large cantilever structures are easy to appear, and the structures are easy to cause deformation, bending and twisting of materials in the extrusion process, and the reasons for the occurrence are often caused by uneven stress when the jaw of the extrusion tractor or the straightener clamps materials.

An automatic aluminum profile straightening machine is disclosed in the chinese patent application publication No. CN 207547280U, in which the contact surface between the clamp and the profile is a plane, but most of the existing profiles are not completely parallel in plane and profile, and if the plane clamp is used, the actual straightening process is deflected, so that the profile is distorted and deformed.

Therefore, the special straightening clamp is designed to better meet the straightening requirement of special sectional materials, ensure uniform stress in the straightening process, reduce deformation caused by the straightening process and correct deformation in the extrusion cooling quenching process.

An auxiliary clamp for extruding a profile of an automobile threshold Liang Lv is applicable to aluminum profiles with planes and profile degrees not completely parallel; comprising the following steps: a lower jig 3 for contacting the lower surface of the aluminum profile 1, and an upper jig 2 for contacting the upper surface of the aluminum profile 1; both the upper clamp and the lower clamp include: a mounting plate and two or more pressing strips 4 arranged on the mounting plate; the pressing strip 4 is used for being matched with the end face contacted with the aluminum profile 1 and the surface corresponding to the aluminum profile 1, so that the end face of the pressing strip is fully contacted with the surface of the aluminum profile, and the aluminum profile is better fixed.

Therefore, in actual use, the main action points of the upper clamp and the lower clamp are the positions of all ribs of the aluminum profile, but not the whole plane, because the plane and the profile of the aluminum profile are not completely parallel, if the plane clamp is adopted, deflection occurs in the actual straightening process, and thus the profile is distorted and deformed; the stress position of the clamp provided by the utility model is concentrated on the rib position of the aluminum profile instead of the plane, so that the full balance of the upper stress and the lower stress can be better ensured, the generation of local deformation is avoided, the weight of the clamp is reduced, and the cost is saved.
