Abstract
The utility model provides a novel independent pressurization deflection compensation mechanism of a bending machine. The novel independent pressurization deflection compensation mechanism of the bending machine comprises a compensation oil cylinder. A pressurization and oil supply system of the compensation oil cylinder of the mechanism is an independent hydraulic pressure oil circuit and is directly communicated with a foot switch. The novel independent pressurization deflection compensation mechanism of the bending machine is designed aiming at problems existing in existing bending machine hydraulic pressure deflection compensation, the independent hydraulic pressure oil circuit is adopted to supply oil by the compensation oil cylinder, stepless regulation of compensatory pressure by the compensatory pressure self can be achieved according to the length and the thickness of foldable manufactured plate materials, the phenomenon that the compensatory pressure and master cylinder pressure are integrated and mutually interferential is eliminated, and foldable manufactured precision and production efficiency of super-long workpieces are greatly improved.
Description
Technical field
The utility model relates to the compensation mechanism of bender patrix slide plate, lower supporting frame deflection deformation when folding workpiece, workpiece is folded the impact of precision thereby thoroughly overcome deflection deformation.
Background technology
There are three large problems in the hydraulic pressure deflection compensation mechanism of domestic existing bender: the one, and the pressurized tank-injection system of compensating cylinder and the oil supply system of master cylinder are integrated, because master cylinder pressurization compensatory pressure of required pressure and compensating cylinder when the bending workpieces is difficult to coupling, when folding workpiece, excessive for easily occurring compensating than the thin plate material, for the undercompensation phenomenon easily occurring than thick blanks, therefore, master cylinder pressure and compensatory pressure are interfered mutually, and operating accuracy is difficult to guarantee; The 2nd, compensating cylinder is fixed on the front and rear support plate on lower supporting frame both sides (sees figure one, existing support plate supporting structure), compensating cylinder supports its compensatory pressure by support plate and acts on lower supporting frame, because front and rear support plate requires rigidity higher (plate is thicker), the manufacture cost is strengthened, and compensate for sensitivity is lower; The 3rd, make-up time and the descending work of master cylinder are advanced crimping and are synchronizeed and carry out, often occur workpiece also unshaped just compensate, the pressurization make-up time can't be adjusted, and does not reach the optimum efficiency of compensation.
Hold concurrently in the problem of above existence, the promotion and application of hydraulic pressure deflection compensation mechanism are very limited, people's great majority are with working experience manual setting patrix wedge, the patrix edge of a knife is adjusted to the approximate arc of intermediate projections, and each workpiece will be adjusted once, labour intensity is large, and production efficiency is low, and workpiece folds precision and is difficult for guaranteeing.
The utility model content:
The utility model purpose is the novel independent pressurization deflection compensation mechanism of a kind of bender of design, the defective that exists to overcome existing bender.
Specifically, the novel independent pressurization deflection compensation mechanism of bender has compensating cylinder, it is characterized in that the pressurization of compensating cylinder and oil supply system are independent hydraulically controlled oil circuit, and directly is communicated with floor push.
The problem that the utility model exists for existing bender hydraulic pressure deflection compensation, the novel independent pressurization deflection compensation mechanism of the bender of design, done from following several respects and improved and obtained beneficial effect:
1. compensating cylinder adopts independent hydraulically controlled oil circuit fuel feeding, compensatory pressure can be according to the length that folds plate and thickness step-less adjustment voluntarily, overcome the phenomenon that compensatory pressure and master cylinder pressure are integrated mutual interference, that has greatly improved super long workpiece folds precision and production efficiency;
2. compensating cylinder is directly installed on bearing support, removed the rigidity support plate with the front support bracket both sides, the manufacturing cost of machine is significantly reduced, the pressure of compensating cylinder directly acts on crossbeam by fore-set, compensate for sensitivity is high, and compensation effect is good, and crossbeam is under the effect of compensating cylinder pressure, the arc that arches upward in the middle of becoming, the machine deflection deformation under patrix slide plate and lower supporting frame middle concave when folding workpiece that thoroughly overcome (compensation);
3. the setting by the electrical system time relay will be adjusted at the moment that the workpiece that folds will be shaped the make-up time, make the deflection compensation effect reach best.The time relay is connected in parallel on the energising port (seeing figure three) of master cylinder pressure charging valve YV1, by adjusting the delay time of the time relay, reach the zero-time of adjusting the compensating cylinder pressurization, the compensation pressurization is consistent with the concluding time of master cylinder supercharging, is controlled by floor push (3); The size of compensatory pressure is regulated (see figure 4) by the remote pressure regulating valve that is arranged in live hydraulic system, by manual rotation pressure regulator valve handle, makes by compensatory pressure and is mated fully by the required balancing force of flap material.
4. surpass national I class precision standard by effectively regulating compensatory pressure and make-up time, make the workpiece accuracy that folds, production efficiency improves tens times.
