Adjusting method.
Background technology
Bender is largely used in sheet metal forming field.Bender is divided into manual bending machine, hydraulic bending press sum number
Control bender.Hydraulic bending press can be divided into again by the method for synchronization turns round synchronous axis, the synchronization of machine liquid and electro-hydraulic synchronous three kinds of forms.Hydraulic pressure
Bender can be divided into again by motion mode：Upper dynamic, lower-moving type.Bender is mounted on by the way that the upper mold on sliding block is opposite
Lower die pressing sheet material on workbench makes plank bend to design angle.Sliding block is mounted on the left and right sidesing wall plate of rack and leads to
Guide rail up and down motion is crossed, the back side is connected to by two groups of linking arms in the balance shaft between the riser of left and right.
A critical issue in bender design and manufacture is exactly the synchronization accuracy of sliding block, i.e., how to ensure sliding block lower plane
With the depth of parallelism problem of work top, that is, on the lower plane of sliding block each point and work top away from difference meet precision mark
Accurate (0.1/1000).Since the unavoidable objective factor such as mismachining tolerance, installation error exists, after necessarily causing sliding block to be installed
It is not parallel between its lower plane and work top, there is this situation, bending angle is unequal along bending line when sheet metal bending, folding
Curved low precision subsequently also needs to carry out secondary correction to plank, time-consuming and laborious, seriously reduces production efficiency；And due to a sliding block left side
Right both ends height is inconsistent, and both sides cylinder force is uneven, can there is the hydraulic shock of system, influences oil cylinder service life, and
It uses for a long time, can also reduce system stability.
Currently, the most common mode of people, is the connection type for connecting rocking bar and sliding block by adjustment axis both ends,
By manually adjusting so that sliding block lower plane is parallel with work top.As Chinese Patent Application No. is：
201520198145.7 publication date is：The patent document on the 12nd of August in 2015, discloses a kind of slider of bender balance adjustment
Mechanism, it includes sliding block, rack, axis body and adjustment plate, and the left and right ends of the rack are respectively provided with a bearing block, described
Axis body is arranged between two bearing blocks, and the left and right ends of axis body are respectively provided with a rocking bar close to the position of bearing block；Described
Adjustment plate is fixed on sliding block, adjustment plate left and right ends be respectively provided with one adjusting connecting rod, adjust connecting rod be equipped with connecting plate, connecting plate with
Rocking bar connects, and the one side of the adjustment plate and shoe contact is equipped with adjustment tank, and the first access and third are equipped in adjustment tank
Adjusting hole, the first access and third adjusting hole are ladder hole, and screw thread is equipped in third adjusting hole；On the sliding block
Equipped with second adjustment hole, second adjustment hole on same axis, is equipped with screw thread with the first access in second adjustment hole.The party
Case adjusts trouble, needs to be possible to sliding block leveling, degree of regulation by repeatedly adjusting by the balance of manual adjusting slider
Difference, easily loosens, and sliding block its degree of balance in up and down motion can change.
For another example, Chinese Patent Application No. is：200920143654.4 publication date is：The patent text on January 13rd, 2010
Part discloses a kind of torsion shaft synchronization regulation device for hydraulic sheet metal torsion shaft bending, includes to be rotatablely installed on the inside of framework pillar
The synchronous sliding block turned round axis and be connected to cylinder piston rod, the synchronous axis both sides of turning round have been respectively fixedly connected with swing arm, sliding
Block inside lower end is fixedly welded with crossbeam, and pedestal is installed on crossbeam, vertical joining beam, joining beam are installed on pedestal
Top be movably hinged and install with the swing arm lower end.The program equally using adjusting manually, and degree of regulation is not high, and sliding block exists
It is easy to happen torsional deformation under the effect of bending load, balance adjustment is influenced, influences bending machining accuracy.

It is inserted into the inner ring hole of self-aligning roller bearing, puts on baffle ring 14 and limited with 15 clamping of eccentric bushing clamp spring and fixed；Bearing block 5 is led to
It crosses axis pin 4 to be installed in the adjustment seat 3 being fixed on wallboard 1, and is packed into leading screw 6 and decelerating motor 12；By feed screw nut 7 and support
Plate 8 connects, and is then installed to supporting plate 8 on eccentric bushing 9 by key, while dial 11 being installed, 8 position of adjustment supporting plate,
Leading screw 6 rotates, and feed screw nut 7 is made to be sleeved on leading screw 6, and adjusts 8 level of supporting plate, i.e., pointer is directed toward dial 11 on eccentric bushing 9
Zero graduation；Then, travel switch 10 is installed on wallboard 1；Finally, the rocking bar at 2 both ends of balance shaft is connect with sliding block, it is complete
At assembly.After being completed, each component connection reliability is checked, ensure that equipment state is normal.
2. measuring height of the both ends of sliding block lower face apart from workbench, and calculate difference in height；
3. parallel with workbench by balance adjustment mechanism adjusting slider lower face, detailed process is：Decelerating motor 12 opens
Dynamic, driving leading screw 6 rotates, and feed screw nut 7 moves on leading screw 6 and supporting plate 8 is pushed to rotate, to which supporting plate 8 drives 9 turns of eccentric bushing
Dynamic, 2 one end of adjustment balance shaft is raised and lowered, so that one end that sliding block is located at eccentric bushing 9 is raised and lowered, when under sliding block
When end face is parallel with workbench, decelerating motor 12 is stopped, and completes balance adjustment operation.In this step, eccentric bushing 9 rotated
In journey the adjusting height of vertical direction be h, thenWherein, S is eccentricity, and χ is leading screw spiral shell
The distance that mother 7 moves on leading screw 6, R are the radius of gyration of supporting plate 8.Adjusting height can be calculated by this formula, to side
Just corresponding scale value is marked on dial 11；In addition, the maximum value that height is adjusted can be controlled by controlling eccentricity S
