Description
Technical field
The utility model relates to the two jaw reels of a kind of symmetric arrangement machinery, belongs to the steel rolling equipment technical field.
Background technology
In strip coiling equipment, reel has two kinds basically to the jaw method of clamping of band steel, and a kind of is hydraulic jaw, and a kind of is mechanical jaw.Jaw is used for clamping steel band, makes reel winding steel under certain tension force.Hydraulic jaw because of relevant component failure leakage of oil, influences product quality easily, and dealing with also influences production efficiency.The jaw of present mechanical jaw reel is arranged the one-sided jaw that is provided with that is a fanning strip in reel, and the regulative mode of jaw opening degree is downward modulation perfect square formula.The mechanical jaw of this form causes being with collapse volume or because of the stressed irregular motion sliding wedge fracture accident that causes of reel of steel easily, and downward modulation perfect square formula is adjusted difficulty, influences production efficiency greatly.
Existing coiler mandrel is made up of mechanical bias jaw and other parts, and jaw is arranged in the one-sided of reel lastblock fanning strip.In the reel operation process,, cause the reel unbalance stress because jaw is not symmetric arrangement, cause coil of strip collapse volume, take off jaw or sliding wedge fracture accident, both influenced lumber recovery, also influence production efficiency, cause the production cost height simultaneously.
As publication number is the Chinese patent of CN201055873, a kind of cold-strip reel reel is disclosed, it comprises mandrel, some fanning strips, fanning strip is installed on the mandrel, the horizontal section in the outside of fanning strip is a circular segment, the mechanism that promotes fanning strip breathing is installed between mandrel and fanning strip, one side jaw of a fanning strip therein, it is characterized in that: the lateral surface at fanning strip is being pasted elastic insert, the outline line in the elastic insert outside is a helix, elastic insert is thick along the thin end of direction one end of circumference, jaw from reel, along the circumference of reel direction along jaw, the thickness of elastic insert is along with from the increase of the arc length of jaw and increase, the thickest near the elastic insert of reel jaw and the position opposite with the jaw direction, from the position opposite with the jaw direction of reel jaw, paste the quantity of the fanning strip of elastic insert, be no less than 1/2nd of fanning strip that reel is installed.The reel jaw of this form also is one-sided setting; the method that this patent will be protected is: paste elastic insert at the lateral surface of fanning strip and eliminate the elastic bumps of band steel in jaw position; the band steel of different size need be changed the combination liner of different-thickness; not only labour intensity is big; consume height, and influence production efficiency.Publication number is the Chinese patent of CN1076667, discloses a kind of power reel reel, belongs to the coiler device of metal tape.It mainly is made up of secter pat (1), rectangular pyramid axle (2), mouth of tongs (3), little jaw (4), arc transition curve (5), arc groove (6) etc.The feature of this patent is in the centre of a fanning strip, a kind of processing method of jaw installation position relevant position, and this kind reel wants to realize that jaw clamps the function of band steel, need be assisted by the jaw hydraulic cylinder and finish.Hydraulic cylinder lost efficacy easily and caused leakage of oil in the course of work, had both influenced product quality, and dealing with also influences production efficiency.CN101185948 relates to a kind of coiling machine sleeve barrel with jaw, comprise 3 above fanning strips, described fanning strip is linked to be an integral body by connecting bolt and junction butterfly spring, it is characterized in that: wherein between two jaw is set at described fanning strip, also comprise jaw slide block, jaw slide block jacking system and jaw slide block resetting means in described jaw position, described jaw slide block and jaw are suitable to coincide, and along with rise footpath and the undergauge of coiler mandrel back and forth is ejected between jaw and retracts under jaw slide block jacking system and the effect of jaw slide block resetting means.This device is a kind of servicing unit that is enclosed within on the coiler mandrel; This device is inserted in reel under reel undergauge state, the expanding force that needs coiler mandrel to produce by the harmomegathus cylinder under the footpath state that rises during work props up this device, could guarantee that this device is connected with the reliable of coiler mandrel, and the jaw of this device is open under the footpath state that rises, steel band can't clamp; This device clamps the band steel by spring force, and clamping force is little, when on the tension coiling production line, using, and can't reliable grip band steel; This device jaw is arranged on the one-sided of a fanning strip between two fanning strips, also has the situation of fanning strip discontinuity during the work of gripping band steel.CN2701549 provides a kind of jaw formula strip coiling device, and its reel inside is equipped with a plurality of harmomegathus cylinder (1a, 1b that are in a straight line, 1c, 1d, 1e), described harmomegathus cylinder (1a, 1b, 1c, 1d, 1e) can radially stretch and an end (2a, 2b 2c) link to each other with the clamping support of forming jaw, (1a's clamping support (2a) outside being positioned at 1b) links to each other with two harmomegathus cylinders that are positioned at the outside.(1a 1b) links to each other because outside clamping support (2a) is with two harmomegathus cylinders.This reel jaw folding is driven by hydraulic pressure harmomegathus cylinder, and the harmomegathus cylinder lost efficacy easily and causes leakage of oil in the course of work, had both influenced product quality, and dealing with also influences production efficiency.
Summary of the invention
The utility model is at the deficiencies in the prior art, the two jaw reels of symmetric arrangement machinery that provide a kind of coiling machine to use.
Technical solutions of the utility model are as follows:
