Description

One kind cutting film machine automatically

Technical field

The utility model is related to steel plate manufacturing technology fields, more particularly to a kind of to cut film machine automatically.

Background technology

Steel plate is to use pouring molten steel, tabular steel made of being suppressed after cooling.Steel plate is tabular, rectangle, can be straight It connects rolling or is sheared by wide strip.Steel plate is by thickness point, 4 millimeters of sheet metal ＜（It is most 0.2 millimeter thin）, medium plate 4~ 60 millimeters, 60~115 millimeters of super-thick steel plate.Steel plate divides hot rolling and cold rolling by rolling point.The width of thin plate is 500~1500 millis Rice；Thick width is 600~3000 millimeters.Thin plate by steel grade point, have ordinary steel, high-quality steel, steel alloy, spring steel, stainless steel, Tool steel, heat resisting steel, bearing steel, silicon steel and ingot iron thin plate etc.；By professional purpose point, there is oil drum plate, enamel plate, prevents Bullet plate etc.；By Coating layer point, there are zinc coated sheet, dry plate, plating flat lead, plastic clad sheet steel etc..It is needed because using It wants, steel plate after processing is completed, is polished, and so that it is had smooth surface, is needed to paste on the steel plate after the completion of polishing Film realizes the protection to steel plate.In current production, there are certain gap, generally 1cm or so between two blocks of steel plates, cut film Device is generally used resistance wire, is moved downward after resistance wire electrified regulation, is inserted into the gap between two blocks of steel plates, film is scalded Disconnected, film is cut in completion.Higher temperature is needed due to scalding disconnected film, electrical current is larger, leads to the usual fracture of wire of resistance wire, is using Shi Tongchang is just needed replacing for 2~3 days, and cost is very high.And the boiling hot disconnected film of resistance wire is more coarse, seriously affects steel plate patch Film quality.Also part of the manufacturer uses the form of cutter, between being inserted into two blocks of steel plates using cutter downlink, using cutter by film Cut-out.But since there is film certain elasticity to be easily deformed, the cutter cut-out relatively difficult to achieve to film, and front and back two pieces Gap between steel plate is simultaneously uneven, is frequently present of gap big, the small situation in another side on one side.Cutter is frequent in cutting process Steel plate can be slided into, surface of steel plate is made to generate cut, seriously affects plate quality, or even formed and scrapped.Currently on the market both It cuts membrane structure and all there is larger defect, it is poor using popularization.Currently, in actual production, it can only be by manually cutting film, not only It is time-consuming and laborious, and seriously affect production efficiency.
