Description

Technical Field

[0001] The present application relates to the technical field of cutter maintenance, and in particular to a cutting device for an aluminum alloy profile extrusion production line. Background Art

[0002] The extrusion process of aluminum alloy profiles refers to extruding aluminum bars heated to a certain temperature into profiles of the desired shape through an extruder. The extruded profiles need to be cut to meet different application requirements. At the same time, the tailings of aluminum bars also need to be cut during the processing due to their low application efficiency.

[0003] During the cutting process of aluminum alloy profiles, the surface of the cutter will carry oxides, dust or grease on the profile when the cutter contacts the profile, and regular cleaning and maintenance are required. Dust or impurities can be removed by blowing or brushing; oxides can be effectively removed by adding weak acid or weak alkali to the cleaning liquid during the brushing process. However, grease has strong adhesion at high temperatures and is difficult to remove by physical methods.

[0004] Grease removers can be used to remove fat from the surface of the cutter. In order to improve labor efficiency, a periodic plan is usually formulated to perform regular maintenance on the cutter. However, the grease on the surface of the cutter will become more difficult to clean after mixing with impurities or oxides during long-term use; if the maintenance cycle of the cutter is shortened, it will lead to increased consumption of labor resources.

[0067] Specifically, after the contact electrode 15 is coated with lipase and contacts the cutter, if there is grease on the surface of the cutter, the lipase reacts with the grease to form an electrical signal; when the voltage on the circuit connecting the contact electrode 15 and the counter electrode exceeds the preset voltage of the comparator, the comparator drives the relay 3 to switch to the normally closed contact through the transistor, and the relay 3 controls one of the magnetic rings 1 or 2 to be energized, so that the contact ring moves, and the switching strategy of the liquid pump 1 or the liquid pump 2 of the water inlet shaft 34 is adjusted by changing the contact state between the contact ring 1 41 or the contact ring 2 42 and the pressing piece. If there is no grease on the surface of the cutter, no electrical signal is generated in the circuit connecting the contact electrode 15 and the counter electrode, and the relay 3 is connected to the normally open contact.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
