Description

Technical Field

[0002] With the progress of modern industry, aluminum extrusion production lines are developing towards large tonnage, high energy efficiency and automation. The previous small tonnage, low energy efficiency and multi-manual machines are gradually being eliminated, which puts forward higher production and process requirements for the rear equipment of aluminum extrusion. The straightening machine, as a profile shaping and correction mechanism in the rear equipment of aluminum extrusion, has many problems caused by it.

[0003] Aluminum bars are made into profile blanks through an extrusion mechanism. Due to the size difference of aluminum bar raw materials, extrusion thermal deformation, traction feeding error and other reasons, there will inevitably be size differences between blanks of different strokes. For the straightening machine that straightens the blanks, it is a prerequisite for profile straightening to clamp both ends of the blanks at the right position. In general production processes, one jaw is often used as a reference, that is, one end of the profile blank is placed near the jaw. Slight size errors are fine-tuned by the main oil cylinder that drives the jaw to pull the material, and the position of the jaw at the other end is mostly adjusted manually by visual adjustment, which is time-consuming and labor-intensive; or photoelectric switch material inspection adjustment, and simple photoelectric switch material inspection is not ideal for profiles with special cross-sections (such as profiles with large light reflection angles).

[0034] The action sequence is as follows: the first cylinder 15 extends, the first conductor 11 moves upward to contact the aluminum profile 5, and the power is turned on to allow the aluminum profile 5 to obtain electrical potential energy; the first cylinder 15 retracts, the first conductor 11 moves downward to separate from the aluminum profile 5, and the power is turned off.

[0035] Optionally, the second detector 6 includes a second conductor, a first guide rail 25, a second cylinder 26, a second guide rail 212, and a third cylinder 21; the second conductor is arranged on the first guide rail 25, and moves along the first direction by the push of the second cylinder 26; the first guide rail 25 is arranged on the second guide rail 212, and moves along the second direction by the push of the third cylinder 21; the first direction is the extension direction of the first guide rail 25, the second direction is the extension direction of the second guide rail 212, and the first direction intersects with the second direction; and further includes a hinge shaft 22, a crank arm 23, and a fourth cylinder 24; one end of the fourth cylinder 24 is fixedly arranged on the first guide rail 25, and the other end is arranged on the hinge shaft 22; The fourth air cylinder 24 is extended, and the crank arm 23 drives the hinge shaft 22 to rotate toward the side close to the first guide rail 25; the second conductor includes a flagpole 27, a sleeve 28, a conductor plate 210, and a graphite strip 211, one end of the flagpole 27 is fixedly arranged on the hinge shaft 22, the sleeve 28 is sleeved on the flagpole 27, one side of the conductor plate 210 is fixedly arranged on the sleeve 28, and the other end is fixedly connected to the graphite strip 211; the second conductor also includes a rubber soft plate 29, and the conductor plate 210 is connected to the flagpole 27 through the rubber soft plate 29.
