Description
Technical field
The utility model belongs to the bar straightener technical field, particularly a kind of bar straightener vertical lift feed mechanism that floats.
Background technology
The feed mechanism of straightener all was to adopt fixedly roller-way mostly in the past, or adopted an elongated pull bar to realize what the roller-way unification was gone up and down.When adopting fixedly roller-way feeding, bar afterbody whipping is very big after the main frame because bar is nipped, and roller-way receives strong strike, and roller-way damages very serious, safeguards very difficulty.And adopt elongated pull bar feeding, because the space structure restriction, the aspect ratio of roller-lifting is less; Simultaneously since the part rod member by compression; So have the pressure bar stabilization problem, and cylinder rod requires than higher with the assembly precision of pull bar, otherwise causes fractureing of cylinder rod easily.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; The purpose of the utility model is to provide a kind of bar straightener vertical lift feed mechanism that floats; Avoid or reduce of the strike of bar afterbody whipping, prolong the service life of roller-way, reduce the maintenance of equipment the feeding roller-way.
In order to achieve the above object, the technical scheme taked of the utility model is:
A kind of bar straightener vertical lift feed mechanism that floats comprises crossbeam 3, and feeding roller-way 1 is installed on the crossbeam 3; The below of crossbeam 3 is connected with left lead 5-2, right lead 5-1 and middle lead 9; Left side lead 5-2 is placed on the left base 7-2, and right lead 5-1 is placed on the right base 7-1, and middle lead 9 is placed on the center base 8; Crossbeam 3 is hinged with the cylinder rod of two hoist cylinders 6; The gudgeon connected modes were installed in respectively on left base 7-2 and the right base 7-1 in the middle of two hoist cylinders 6 adopted, and the middle gudgeon employing square crossing installation that the jointed shaft that hoist cylinder 6 connects with crossbeam 3 and hoist cylinder 6 are connected with left and right sides base 7 is separately installed with two couples first spring top roller 4-2 in the side of left lead 5-2; Side at right lead 5-1 is separately installed with two couples second spring top roller 4-1; The first spring top roller 4-2 is installed on the left base 7-2, and the second spring top roller 4-1 is installed on the right base 7-1, between the both sides up and down of three leads and the corresponding base copper shoe 10 is installed.
The characteristics of the utility model are: adopted the mode of hydraulic lifting to realize; The mode of spring top clamping that adopts left and right sides has realized floating spacing; The jointed shaft of gudgeon and cylinder rod adopts the square crossing mounting means in the middle of the hoist cylinder simultaneously, makes feeding roller-way and crossbeam realize freedom on the four direction all around, thereby has guaranteed can swing after feeding roller-way and crossbeam are hit by bar; Avoid excess impact; Thereby the protection roller-way prolongs its service life, has reduced the workload of plant maintenance simultaneously.

Fig. 3 is the lead sectional view of the utility model, and wherein Fig. 3-1 is the sectional view of left lead 5-2, and Fig. 3-3 is the sectional view of right lead 5-1, and Fig. 3-2 is the sectional view of middle lead 9.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
With reference to Fig. 1, Fig. 2 and Fig. 3; A kind of bar straightener vertical lift feed mechanism that floats comprises crossbeam 3, and feeding roller-way 1 is installed on the crossbeam 3; The below of crossbeam 3 is connected with left lead 5-2, right lead 5-1 and middle lead 9; Left side lead 5-2 is placed on the left base 7-2, and right lead 5-1 is placed on the right base 7-1, and middle lead 9 is placed on the center base 8; Crossbeam 3 is hinged with the cylinder rod of two hoist cylinders 6; The gudgeon connected mode was installed on left base 7-2 and the right base 7-1 in the middle of hoist cylinder 6 adopted, and the middle gudgeon employing square crossing installation that the jointed shaft that hoist cylinder 6 connects with crossbeam 3 and hoist cylinder 6 are connected with left and right sides base 7 is separately installed with two couples first spring top roller 4-2 in the side of left lead 5-2; Side at right lead 5-1 is separately installed with two couples second spring top roller 4-1; The first spring top roller 4-2 is installed on the left base 7-2, and the second spring top roller 4-1 is installed on the right base 7-1, between the both sides up and down of three leads and the corresponding base copper shoe 10 is installed.
The operation principle of the utility model is:
At first dialled in the feeding roller-way 1 on foreground from the stand by aligning bar 2; Feeding roller-way 1 rises under the effect of hoist cylinder 6 with crossbeam 3; Travelled forward gradually under the driving of feeding roller-way 1 by aligning bar 2; Up to the first pair of smoothing roll of main frame of being nipped by aligning bar 2 heads, at this moment bar can travel forward under the effect of main frame smoothing roll fully, is aligned simultaneously.Foreground feeding this moment roller-way 1 descends rapidly under the effect of hoist cylinder 6 with crossbeam 3, drops to the below of fender bracket, avoids the strike of bar whipping.In lifting process, the copper shoe 10 of three lead both sides plays good sliding action, reduces frictional force, improves its service life.
In the process that descends; Quilt aligning bar 2 has rotated under the effect of main frame smoothing roll and has advanced, and crooked bar hits feeding roller-way 1 when rotation is advanced, and feeding roller-way 1 is after receiving by 2 strikes of aligning bar; Can swing around the gudgeon pin joint of hoist cylinder 6; One side, the second spring top roller 4-1 is compressed, and the opposite side first spring top roller 4-2 obtains discharging, thereby effectively alleviates the excess impact of bar to feeding roller-way 1.
After hitting; The second spring top roller 4-1 of compression begins retracting spring power; Feeding roller-way 1 and crossbeam 3 are promoted in the opposite direction, make feeding roller-way 1 and crossbeam 3 get back to initial position, thereby realized the unsteady feeding of feeding roller-way 1; Reduce the impact injury of feeding roller-way 1, prolonged its service life.
