Abstract
The utility model discloses a spring balance device, and relates to the technical field of bending machines. The spring balance device comprises a connecting rod (1), a supporting plate (2), a spring (3), and a nut (4), wherein the supporting plate (2) is connected on a machine frame (5) in a welding mode, one end of the connecting rod (1) penetrates through a central hole of the supporting plate (2) to be connected with a cutter rest (6), the spring (3) is connected on the connecting rod (1) in a sleeved mode, and the upper end of the spring (3) is fixed on the connecting rod (1) through the nut (4). Elastic force of the spring offsets gravity of the cutter rest, therefore during the process of running, the gravity of the cutter rest is not completely borne by an oil cylinder and a servo motor, and balance of a lathe is improved.
Description
Technical field:
The utility model relates to the bender technical field, is specifically related to a kind of spring equalizing device for numerical control bender.
Background technology:
Bender is a kind of machine that can carry out bending to thin plate, its structure mainly comprises support, workbench and clamping plate, workbench places on the support, workbench is made of base and pressing plate, base links to each other with clamping plate by hinge, base is made up of seat shell, coil and cover plate, and coil places in the depression of a shell, and recessed top is covered with cover plate.During use by lead to coil electricity, energising back produces gravitation to pressing plate, thereby realizes the clamping to thin plate between pressing plate and the base.Owing to adopted the electromagnetic force clamping, make pressing plate can make the various workpieces requirement, and can process the workpiece that sidewall is arranged, also very easy in the operation.
The gravity of the knife rest of existing bender is to be born by oil cylinder and servomotor, because the gravity of knife rest brings burden can for when motion oil cylinder and servomotor, shortens the life-span of oil cylinder and servomotor, and has reduced the balance of lathe, uses inconvenient.
The utility model content:
The purpose of this utility model provides a kind of spring equalizing device, and it makes the gravity of running intermediate slide do not born by oil cylinder and servomotor entirely by the gravity of the elastic force counteracting knife rest of spring, has improved the balance of lathe.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises connecting rod 1, gripper shoe 2, spring 3, nut 4, gripper shoe 2 is welded on the frame 5, the centre bore that one end of connecting rod 1 passes gripper shoe 2 is connected with knife rest 6, spring 3 is socketed on the connecting rod 1, and the upper end of spring 3 is fixed on the connecting rod 1 by nut 4.
The utility model is by the combination of connecting rod 1 with spring 3, and the elastic force of spring 3 can be offset the gravity of knife rest 1, makes the gravity of running intermediate slide do not born by oil cylinder and servomotor entirely, has improved the balance of lathe.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it comprises connecting rod 1, gripper shoe 2, spring 3, nut 4, gripper shoe 2 is welded on the frame 5, the centre bore that one end of connecting rod 1 passes gripper shoe 2 is connected with knife rest 6, spring 3 is socketed on the connecting rod 1, and the upper end of spring 3 is fixed on the connecting rod 1 by nut 4.
This specific embodiment is by the combination of connecting rod 1 with spring 3, and the elastic force of spring 3 can be offset the gravity of knife rest 1, makes the gravity of running intermediate slide do not born by oil cylinder and servomotor entirely, has improved the balance of lathe.
