Abstract
The utility model provides a high speed partial cutting flying shear of a headless rolling strip steel. The utility model is composed of an upper rotary hub and a lower rotary hub 1, a left machine frame and a right machine frame 2, a flying shear driving device 3, a blade clearance automatic regulation mechanism 4, a machine frame pretension mechanism 5, a machine frame locking mechanism 6 and a base 7. The machine frame locking mechanism 6 is composed of a draw rod 8, a high-pressure plunger cylinder 9, a screw nut 10, a helical casing 11 and a cushion ring 12 and can respectively carry out locking in vertical direction for the left machine frame and the right machine frame 2, and the machine frames are fixed on the base 7. Because the utility model adopts the high-pressure plunger cylinder to carry out locking for the left machine frame and the right machine frame in vertical direction, the occupied space of the machine frame locking mechanism in side direction is reduced, and reaction speed is raised. The utility model has the advantages of convenient operation, favorable locking effect, etc.
Description
Technical field
The utility model relates to a kind of flying shearing machine, and the high speed that especially a kind of band steel that is used for after the cold continuous rolling endless rolling is sheared under the high-speed cruising condition is cut flying shear.
Prior art
At present, the flying shear in the tandem mills exit all utilizes computer system tracking band to control end to end, automatically and cuts band, mainly is in order to reduce band loss end to end, to improve lumber recovery.When shearing the different-thickness band, for realizing online rapid adjustment blade clearance, require the flying shear rotary inertia little, startup during work, acceleration, shearing, reduction of speed, stop quick and precisely, require the linear velocity of cutting edge when shearing consistent simultaneously with the speed of service of being with steel.Flying shear is mainly formed by changeing hub, left and right sides frame, flying shear transmission mechanism, blade clearance automatic mechanism, frame pretightening mechanism, rack locking mechanism, base up and down.Change hub up and down and be installed on the frame of the left and right sides, left and right sides frame is an open architecture, and mechanism fits together by frame pretightening.Change hub up and down by the transmission of flying shear transmission mechanism, realize the shearing of band steel.The flying shear transmission mechanism is made up of a direct current generator, reductor, gear coupling, major-minor gear, changes up and down between hub and realizes rotating synchronously by the major-minor gear.Frame is fixed on the base by rack locking mechanism about when flying shear works online, and when flying shear need shift out beyond the production line, rack locking mechanism unclamped, and by traversing hydraulic cylinder flying shear is moved to beyond the production line.Because present flying shear all is the mode that adopts the hydraulic cylinder side direction that left and right frame is locked, and the stroke of hydraulic cylinder selects for use about 200mm mostly, and the project organization of this locking mode is not only bigger in the side direction occupation space, and reaction speed is slow.
Summary of the invention
The purpose of this utility model is to provide the endless rolling band steel that a kind of side direction that can reduce retaining mechanism takes up room, reaction speed is fast to cut flying shear at a high speed.
The purpose of this utility model is achieved in that this endless rolling band steel cuts flying shear at a high speed and mainly formed by changeing hub, left and right sides frame, flying shear transmission mechanism, blade clearance automatic mechanism, frame pretightening mechanism, rack locking mechanism, base up and down.Wherein rack locking mechanism is made up of pull bar, high-voltage plunger cylinder, nut, respectively left and right frame is carried out vertical direction locking, and frame is fixed on the base.
Endless rolling band steel of the present utility model is cut flying shear at a high speed, and the stroke of the high-voltage plunger cylinder in its rack locking mechanism is 30～80mm.
The utility model is owing to adopt high-voltage plunger cylinder that left and right frame is carried out vertical direction locking, the side direction that has reduced rack locking mechanism takes up room (almost identical with the frame width), (range of high-voltage plunger cylinder is all in 80mm to have improved reaction speed, range can reach 30mm in case of necessity), and have advantages such as easy to operate, that locking effect is good.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～4, endless rolling band steel of the present utility model is cut flying shear at a high speed, is mainly formed by changeing hub 1, left and right sides frame 2, flying shear transmission mechanism 3, blade clearance automatic mechanism 4, frame pretightening mechanism 5, rack locking mechanism 6, base 7 up and down.Wherein rack locking mechanism 6 is made up of pull bar 8, high-voltage plunger cylinder 9, nut 10, thread bush 11 and packing ring 12, respectively left and right frame 2 is carried out vertical direction locking, and frame is fixed on the base 7.In addition, according to producing actual needs, endless rolling band steel of the present utility model is cut flying shear at a high speed, and the stroke of its high-voltage plunger cylinder 9 can be selected 30mm, 38mm, 50mm, 65mm, 80mm.When needs are locked frame, by the oiling in high-voltage plunger cylinder 9 of high pressure manual pump, the elongation of the plunger outward of high-voltage plunger cylinder 9, when plunger outward was extended, pull bar 8 and high-voltage plunger cylinder 9 just were locked in frame on the base.When the frame needs are mobile, the high pressure in the high-voltage plunger cylinder 9 are shed, the plunger of high-voltage plunger cylinder 9 is inwardly withdrawn, and frame is just released.Because this project organization is that left and right frame is carried out vertical direction locking, so reduced that the side direction of rack locking mechanism takes up room (almost identical with the frame width), (range of high-voltage plunger cylinder is all in 80mm to have improved reaction speed, range can reach 30mm in case of necessity), and have advantages such as easy to operate, that locking effect is good.
