Large aluminum profile straightening machine automatic lifting and feeding mechanism

Abstract

The invention belongs to the field of metal profile straightening and relates to a large aluminum profile straightening machine automatic lifting and feeding mechanism which sequentially comprises a bottom frame, a middle frame, an upper frame and a swinging mechanism from bottom to top; a plurality of limiting frames with a groove-shaped bracket structure are fixedly installed on the two sides of the bottom frame; a plurality of groups of slanting irons and rolling wheels are fixedly installed at the lower part of the two sides of the upper frame; the rolling wheels are assembled in grooves of the limiting frames respectively; a plurality of rolling wheels with bearings are installed on the middle frame; the slanting surfaces of the slanting irons are in contact to the rolling wheels of the middle frame respectively; a lifting oil cylinder component is connected to the outer side of the middle frame; supporting seats in the swinging mechanism are fixedly installed at the upper part of the upper frame; a rotary shaft with the two ends fixed on the supporting seats respectively is fixedly installed between swinging frames; crank arms are fixedly installed at the middle part of the rotary shaft; and one end, far away from the swing frames, of each crank arm is hinged to a swinging oil cylinder component, so that the problems that feeding by lifting mechanism at a front nip and a back nip enables overlong middle section of a profile to be hung in air and a flexible region to be overlarge in deformation, so that the quality of the profile is lowered; and overlarge deformation can enable the front nip and the back nip not to be liable in clamping, so that the waste head is long are solved.

Description

technical field [0001] The invention belongs to the field of straightening metal profiles, and relates to an automatic lifting and feeding mechanism for a large-scale aluminum profile straightening machine. Background technique [0002] With the progress of modern industry, the aluminum profile extrusion production line is developing in the direction of large tonnage, high energy efficiency, and automation. The previous small tonnage, low energy efficiency, and multi-manual machines are gradually being eliminated, which also affects aluminum profile extrusion. The rear equipment puts forward higher requirements for production and process flow. As the profile shaping and correcting mechanism in the rear equipment of aluminum profile extrusion, the straightening machine has many problems caused by the increase in tonnage. [0003] For small machines, the workers who stand near the front and rear jaws manually feed the straightening machine jaws directly; or the lifting mechan...

AI Technical Summary

Problems solved by technology

[0005] In view of this, in order to solve the problem that the middle section of the too long profile is suspended in the air only through the lifting mechanism of the front and rear jaws, the excessive deformation of the flex zone will cause the quality of the profile to decline; excessive deformation will make it difficult to clamp when the front and rear jaws are clamped. , the problem of long waste head, provide an automatic lifting and feeding mechanism for large aluminum profile straightening machine
