Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to an automatic oil brushing mechanism for a bending machine. Background Technique

[0002] A bending machine is a machine that can bend thin plates. Due to repeated bending, it is necessary to brush oil on the bending part to reduce the friction force on the thin plate and ensure smooth bending. In order to improve the oil brushing efficiency, an automatic oil brushing mechanism is equipped on the bending machine. After retrieval, a Chinese patent with the publication number CN216226276U discloses an automatic oil brushing mechanism for a bending machine, including a processing table. A cross beam frame is arranged on the top of the processing table, and a ball screw is arranged inside the cross beam frame. The ball screws are symmetrically distributed left and right about the bisector of the cross beam frame. A first cross plate is arranged inside the ball screw, and an air duct is arranged at the bottom of the first cross plate. An air outlet is arranged at the bottom of the air duct, and a conveying pipeline is arranged on one side of the air duct. A blower is arranged on the first cross plate. This automatic oil brushing mechanism for a bending machine longitudinally arranges ball screws inside the cross beam frame on the processing table, arranges a first cross plate inside the ball screws, and simultaneously arranges an air duct, an air outlet and an oil brushing sponge at the bottom of the first cross plate. Thus, after the plate is bent, the dust on the surface of the plate can be blown away through the air outlet first, and then the rust preventive oil can be brushed on the surface of the plate through the oil brushing sponge. The automation degree is relatively high, which reduces the pressure on the staff. However, it is not convenient to complete the oil brushing operation while bending, which is likely to reduce the bending efficiency, and its structure is complex, and the manufacturing cost and maintenance cost are relatively high.

[0025] Embodiment:

[0026] Please refer to Figures 1-8, an automatic oil brushing mechanism for a bending machine, comprising a bending machine and an automatic oil brushing mechanism arranged on the bending machine, the bending machine comprising a bending block 2 and a V-shaped bending groove 1 arranged opposite to each other up and down, the automatic oil brushing mechanism is arranged in two groups and is arranged on both sides of an opening of the V-shaped bending groove 1, the automatic oil brushing mechanism comprises a roller 3 with an oil brushing sleeve 4, brush grooves 11 are provided on the upper parts of both sides of the opening of the V-shaped bending groove 1, the roller 3 is rotatably connected to the brush groove 11, and an oil groove 5 fixedly installed on the outside of the V-shaped bending groove 1 is provided below the roller 3, and a guide mechanism arranged at the end of the V-shaped bending groove 1 is also provided above the two automatic oil brushing mechanisms.

[0027] Specifically, the guiding mechanism includes a slide 6 that can slide perpendicularly to the inner wall of the V-shaped bending groove 1, and a guide roller 7 is rotatably connected to the slide 6. Through the setting of the guide roller 7, when the thin plate placed between the two guide rollers 7 is pressed downward by the bending block 2, the guide rollers 7 and the slide 6 are pushed outward so that the thin plate is guided by the guide rollers 7 and is pressed against the inner wall of the bending block 2 starting from the end of the V-shaped bending groove 1.

[0028] Specifically, it also includes an elastic component adapted to the slide 6, the elastic component includes a spring 12, a slide plate 8 is fixedly installed on the slide 6, and a slide rod 9 fixedly connected to the V-shaped bending groove 1 is slidably matched on the slide plate 8. A limit block 10 is fixedly installed on the side of the slide rod 9 away from the V-shaped bending groove 1. The spring 12 is sleeved on the slide rod 9 and the two ends of the spring 12 are respectively fixedly connected to the slide plate 8 and the limit block 10. Through the cooperation of the slide plate 8, the slide rod 9, the limit block 10 and the spring 12, it is easy to drive the slide 6 and the guide roller 7 to slide perpendicular to the inner wall of the V-shaped bending groove 1 as a whole. When the thin plate is pressed down, the guide roller 7 is pushed to slide outward. When the downward pressure is released, the bent thin plate is pushed up under the action of the rebound force of the spring 12, so that it is out of contact with the inner wall of the V-shaped bending groove 1, thereby facilitating unloading.

[0029] Specifically, the bending machine also includes a supporting base for supporting the V-shaped bending groove 1, and the supporting base includes a bottom plate 13. The bottom of the V-shaped bending groove 1 is fixedly connected to the bottom plate 13 through a plurality of support blocks 14, and the bottom end of the oil tank 5 is in contact with the top of the support block 14. Through the cooperation of the bottom plate 13 and the support block 14, it is convenient to support the V-shaped bending groove 1 and increase the stability during bending. Through the contact between the oil tank 5 and the support block 14, the oil tank 5 can be supported to increase the stability of the structure.

[0030] Specifically, the bending machine further includes a lifting mechanism for lifting the bending block 2. The lifting mechanism includes a gantry 15 erected above the V-shaped bending groove 1. The gantry 15 is fixedly connected to the bottom plate 13. A driving cylinder 16 is vertically and fixedly installed on the gantry 15. The bottom output end of the driving cylinder 16 is fixedly connected to the top end of the bending block 2. Through the cooperation of the gantry 15 and the driving cylinder 16, it is convenient to move the bending block 2 downward, and then cooperate with the V-shaped bending groove 1 to bend the thin plate.

[0031] Specifically, multiple sets of guide rollers 7 on the carriage 6 are arranged at intervals and rotatably connected to the carriage 6, which improves the stability of the support of the guide rollers 7 for the thin plate and avoids the situation that a single guide roller 7 is bent under pressure.
