Background technology
In sheet metal forming field in a large number using bender.Bender is divided into manual bending machine, hydraulic bending press sum
Control bender.Hydraulic bending press can be divided into torsion axle synchronization, machine liquid three kinds of forms of synchronous and electro-hydraulic synchronization by the method for synchronization again.Hydraulic pressure
Bender can be divided into by motion mode again：Upper dynamic, lower-moving type.Bender is mounted opposite by the upper mould being arranged on slide block
Bottom punch pressing plate material on workbench is making sheet material bend to design angle.Slide block is arranged on the left and right sidesing wall plate of frame and leads to
Cross guide rail to move up and down, the back side is connected in the balance shaft between the riser of left and right by two groups of linking arms.
Bender one of manufactures and designs the synchronization accuracy that key issue is exactly slide block, how to ensure slide block lower plane
With the depth of parallelism problem of work top, that is, on the lower plane of slide block each point and work top away from difference meet precision mark
Accurate (0.1/1000).Because the unavoidable objective factor such as mismachining tolerance, alignment error exists, after necessarily leading to slide block to be installed
Not parallel between its lower plane and work top, this situation occurs, during sheet metal bending, bending angle is unequal along along bending line, folding
Curved low precision, subsequently also needs to carry out secondary correction to sheet material, wastes time and energy, and seriously reduces production efficiency；And because slide block is left
Right two ends are highly inconsistent, and both sides cylinder force is uneven, can there is the hydraulic shock of system, affect oil cylinder service life, and
Long-time use, also can reduce system stability.
At present, the most frequently used mode of people, is the connected mode connecting rocking bar and slide block by adjustment axle two ends,
By manually adjusting so that slide block lower plane is parallel with work top.As Chinese Patent Application No. is：
201520198145.7, publication date is：In August, 2015 patent documentation of 12 days, discloses a kind of slider of bender balance adjustment
Mechanism, it includes slide block, frame, axis body and adjustment plate, and the left and right of described frame is respectively arranged at the two ends with a bearing block, described
Axis body is arranged between two bearing blocks, and the left and right two ends of axis body are respectively provided with a rocking bar near the position of bearing block；Described
Adjustment plate is fixed on slide block, is respectively arranged at the two ends with a regulation connecting rod, adjusts connecting rod and be provided with connecting plate about adjustment plate, connecting plate with
Rocking bar connects, and described adjustment plate is provided with adjustment tank with the one side of shoe contact, is provided with the first access and the 3rd in adjustment tank
Adjusting hole, the first access and the 3rd adjusting hole are ladder hole, and the 3rd adjustment in the hole is provided with screw thread；On described slide block
It is provided with the second adjusting hole, on same axis, the second adjustment in the hole is provided with screw thread for the second adjusting hole and the first access.The party
The balance of case manually adjusting slider, adjusts trouble, needs being possible to slide block leveling, degree of regulation through multiple regulation

Embodiment 2
The present embodiment provides a kind of method that slider of bender depth of parallelism is adjusted, electronic flat using the bender of embodiment 1
Weighing apparatus adjusting means is adjusted, and comprises the following steps that：
1. equipment assembling is carried out according to the structure in embodiment 1, number of assembling steps is as follows：
First balance shaft 2 is tilted to be placed between two wallboards 1, then its one end is inserted in the installing hole of wallboard 1, and from
Reach the outside of wallboard 1 inside wallboard 1, then the other end of balance shaft 2 is inserted in the installing hole of another wallboard 1；So
With driving, balance shaft 2 is sling afterwards, make balance shaft 2 axis and wallboard 1 upper installing hole center alignment, self-aligning roller bearing is knocked in
Do not install in the installing hole of wallboard 1 of balance adjustment mechanism side, and make balance shaft 2 end insert the inner ring of self-aligning roller bearing
Kong Zhong, installs end cap 16 from wallboard 1 outside, blending bolt fastens；Take a self-aligning roller bearing again, load the inclined of eccentric bushing 9
In heart hole 902, first wear-resistant sleeve 13 is knocked in wallboard 1 upper installing hole, then eccentric bushing 9 is loaded onto, and make the end of balance shaft 2
In the inner ring hole of insertion self-aligning roller bearing, put back-up ring 14 and with the spacing fixation of eccentric bushing jump ring 15 clamping；Bearing block 5 is led to
Cross bearing pin 4 to be installed in the adjustment seat 3 being fixed on wallboard 1, and load leading screw 6 and reducing motor 12；By feed screw nut 7 and support
Plate 8 connects, and is then installed on eccentric bushing 9 supporting plate 8 by key, installs graduated disc 11 simultaneously, adjusts supporting plate 8 position,
Leading screw 6 rotates, and so that feed screw nut 7 is enclosed within leading screw 6, and adjusts supporting plate 8 level, and that is, on eccentric bushing 9, pointer points to graduated disc 11
Zero graduation；Then, travel switch 10 is installed on wallboard 1；Finally, the rocking bar at balance shaft 2 two ends is connected with slide block, complete
Become assembling.After being completed, check each part connection reliability it is ensured that equipment state is normal.
2. measure the height apart from workbench for the two ends of slide block lower surface, and calculate difference in height；
3. parallel with workbench by balance adjustment mechanism adjusting slider lower surface, detailed process is：Reducing motor 12 opens
Dynamic, drive leading screw 6 to rotate, feed screw nut 7 moves on leading screw 6 and promotes supporting plate 8 to rotate, thus supporting plate 8 drives 9 turns of eccentric bushing
Dynamic, adjustment balance shaft 2 one end is raised and lowered, and then one end that slide block is located at eccentric bushing 9 is raised and lowered, when under slide block
When end face is parallel with workbench, reducing motor 12 quits work, and completes balance adjustment operation.In this step, eccentric bushing 9 rotated
In journey, the regulation height in vertical direction is h, thenWherein, S is eccentric throw, and χ is feed screw nut
7 on leading screw 6 movement distance, R be supporting plate 8 the radius of gyration.Regulation height can be calculated by this formula, thus convenient
Corresponding scale value is marked on graduated disc 11；In addition, by control eccentric throw S can control altitude mixture control maximum and
Minima, feed screw nut 7 ratio apart from χ and the radius of gyration R of supporting plate 8 of movement on leading screw 6 can control leading screw 6 rotating speed with
The ratio of the angular velocity that eccentric bushing 9 rotates is such that it is able to realize high-precision regulation.In the present embodiment, S=4mm, take χ=45 π
Mm, R=180mm, thenThat is, leading screw spiral shell
Female 7 on leading screw 6 mobile 45 π mm distances, eccentric bushing 9 is 2mm in the regulation height of vertical direction, that is, one end of slide block rise or
Decline 2mm.
At ordinary times when using, when needing to be adjusted, by the quarter on the graduated disc 11 indicated by pointer on eccentric bushing 9
Degree can determine the distance that slide block rises or falls.
Step 3. in, when supporting plate 8 rotates clockwise or counterclockwise and exceedes set angle, supporting plate 8 and travel switch 10
Contact, travel switch 10 produces the signal of telecommunication and is sent to control system, and control system controls reducing motor 12 to quit work, thus
Supporting plate 8 is stopped operating, it is to avoid feed screw nut 7 displacement on leading screw 6 goes beyond the scope, and plays the effect of safeguard protection.
Example described in the utility model is only preferred implementation of the present utility model to be described, not to this reality
It is defined with new spirit and scope, on the premise of without departing from this utility model design philosophy, this area engineering technology people
Various modifications and improvement that member makes to the technical solution of the utility model, all should fall into protection domain of the present utility model.
