Abstract

A gas-liquid joint fast shearing device of the aluminum strip rolling mill primarily comprises an upper knife body, a lower knife body, a hydraulic cylinder (7) and a barometric cylinder (8). The upper blade(1) of the upper knife body is fixed on a movable upper tool-holder (2) connected with the hydraulic cylinder, the lower terminal of the hydraulic cylinder is connected with a barometric cylinder the lower part of which is fixed at a beam (9), both ends of the beam is arranged to the rack(10) , a pinion and rack synchronous mechanism (6) is arranged at the upper part of the rack, the rack of the pinion and rack synchronous mechanism is fixed on the rack while the pinion at the movable upper tool-holder; The lower blade (4) of the lower knife body is fixed on the lower tool-holder (5). A transient guiding plate (3) is arranged on the lower tool-holder which is fixed arranged at the rack. The utility model decreases the strip deposit on the roll system inlet side while the mill cutting strips, and prevents fire.

Description

A kind of aluminium strip rolling mill dynamic hydraulic combined is cut device soon

Technical field:

The utility model relates to Aluminium Cold Rolling machine unit auxiliaries technical field, and particularly a kind of aluminium strip rolling mill dynamic hydraulic combined is cut device soon.

Background technology:

At present, the Aluminium Cold Rolling machine is in the strip-rolling process, because the defective that band exists, tend to produce the phenomenon of broken belt, and along with aluminium strip rolling mill speed constantly improves, in case the milling train broken belt, to cause roller is that a large amount of bands of entrance side are piled up, be easy to cause fire, and broken belt easy to clean not, normally carrying out of aluminium strip rolling mill Rolling Production influenced.

Summary of the invention:

For overcoming the problem that above-mentioned conventional apparatus exists, the purpose of this utility model provides a kind of aluminium strip rolling mill dynamic hydraulic combined and cuts device soon, and the actuating unit that it adopts hydraulic cylinder and cylinder to combine has been realized the band in the mill milling process is cut off fast.

For achieving the above object, the utility model adopts following technical scheme:

Described a kind of aluminium strip rolling mill dynamic hydraulic combined is cut device soon, it mainly is made up of upper knife body, lower knife body, hydraulic cylinder and cylinder, cutter on the upper knife body is fixedly mounted on the mobile upper tool post, mobile upper tool post and hydraulic cylinder link, a hydraulic cylinder lower end and a cylinder link, the cylinder lower end is fixedly mounted on the crossbeam, the two ends of crossbeam are fixed on the frame, the top of frame is provided with the rack-and-pinion lazy-tongs, the tooth bar of rack-and-pinion lazy-tongs is fixedly mounted on the frame, and the gear of rack-and-pinion lazy-tongs is fixedly mounted on the mobile upper tool post; Bottom knife on the lower knife body is fixedly mounted on the lower slide, device-transition guide plate on the lower slide, and lower slide is fixedly mounted on the frame.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

Described a kind of aluminium strip rolling mill dynamic hydraulic combined is cut device soon, when the broken belt accident takes place in it in the mill milling process, can rapidly band in time be cut off, roller is an entrance side band accumulating amount when effectively having reduced the milling train broken belt, avoid causing fire, guaranteed normally carrying out of aluminium strip rolling mill Rolling Production.

Description of drawings:

Fig. 1 is that a kind of aluminium strip rolling mill dynamic hydraulic combined is cut the apparatus structure schematic diagram soon;

Fig. 2 is that a kind of aluminium strip rolling mill dynamic hydraulic combined is cut the upper knife body in the apparatus structure schematic diagram and the structure for amplifying schematic diagram of lower knife body soon;

Number in the figure: 1-cutter; 2-moves upper tool post; The 3-transition guide plate; The 4-bottom knife; The 5-lower slide; 6-rack-and-pinion lazy-tongs; The 7-hydraulic cylinder; The 8-cylinder; The 9-crossbeam; The 10-frame.

The specific embodiment:

As Fig. 1, shown in 2: this aluminium strip rolling mill dynamic hydraulic combined is cut device soon, it is mainly by upper knife body, lower knife body, hydraulic cylinder (7) and cylinder (8) are formed, cutter on the upper knife body (1) is fixedly mounted on the mobile upper tool post (2), mobile upper tool post (2) links with hydraulic cylinder (7), hydraulic cylinder (7) lower end links with-cylinder (8), cylinder (8) lower end is fixedly mounted on the crossbeam (9), the two ends of crossbeam (9) are fixed on the frame (10), the top of frame (10) is provided with rack-and-pinion lazy-tongs (6), the tooth bar of rack-and-pinion lazy-tongs (6) is fixedly mounted on the frame (10), and the gear of rack-and-pinion lazy-tongs (6) is fixedly mounted on the mobile upper tool post (2); Bottom knife on the lower knife body (4) is fixedly mounted on the lower slide (5), and lower slide (5) is gone up device one transition guide plate (3), and lower slide (5) is fixedly mounted on the frame (10).

When milling train was started working, at first airdraulic actuator plunger shaft entrance pressure was so that airdraulic actuator all is provided by the scissors opening degree when being with to provide band to wear; After having worn band, make the oil-feed of hydraulic cylinder rod chamber again, the pulling upper scissor blade enters position to be cut, stroke when reducing to shear; When the band broken belt, after detecting, the broken belt switch that installs behind the machine sends signal, the pneumatic THE ADIABATIC SHEAR IN of cylinder (8) bar chamber air inlet pulling upper scissor blade.
