Description

Technical Field

[0001] The utility model relates to the field of sheet processing equipment, in particular to a sheet bending machine for sheet processing. Background Technique

[0002] The sheet bending machine is a commonly used equipment in the metal processing industry, which is used to bend flat materials at a predetermined angle to meet the needs of various industrial manufacturing. The existing sheet bending machines usually include a workbench, a bending die and a hydraulic system. The upper die is driven by the hydraulic system to apply pressure to the sheet, so that the sheet forms the required bending shape in the bending groove of the lower die. These devices are widely used in the fields of metal processing, automobile manufacturing, construction, etc.

[0003] However, there are some deficiencies in the existing sheet bending machines during use. For example, the replacement of the bending die is relatively complicated, which requires a lot of time and manpower and is difficult to quickly adapt to the processing requirements of different specifications of sheets. Secondly, during the bending process, there is a lack of an effective protection mechanism, which easily leads to uneven stress at the bottom of the bent part of the sheet, affecting the bending effect and the overall quality of the sheet.

[0004] Therefore, we propose a sheet bending machine for sheet processing. Content of the Utility Model

[0023] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a plate bending machine for plate processing includes a workbench 1, an adjusting and bending mechanism, and a bending protection mechanism.

[0024] An adjusting and bending mechanism is provided on the upper surface of the workbench 1. The adjusting and bending mechanism includes a moving plate 2, a lower die 3, an upper die 6, and a connecting plate 7. An adjusting groove is opened on the upper surface of the workbench 1. A moving plate 2 is slidably connected in the adjusting groove. Three uniformly distributed lower dies 3 are fixedly connected to the upper surface of the moving plate 2. A bending groove 9 is opened on the upper surface of the lower die 3. An upper die 6 is provided above the moving plate 2. The top end of the upper die 6 is fixedly connected to a connecting plate 7. The connecting plate 7 is fixedly connected to the output end of an external hydraulic cylinder, thereby providing a stable and powerful bending force. A limiting rod 8 is fixedly connected to the upper surface of the adjusting groove. The moving plate 2 passes through the limiting rod 8 and is slidably connected thereto. Three uniformly distributed limiting grooves 4 are opened on the right end surface of the moving plate 2. A sliding groove is opened on the upper surface of the workbench 1. A locking rod 5 is inserted into the sliding groove, and the locking rod 5 is inserted into the limiting groove 4.

[0025] It should be noted that the adjusting and bending mechanism realizes the flexible adjustment of the position of the lower die 3 through the sliding connection between the adjusting groove on the workbench 1 and the moving plate 2, so as to quickly adapt to the processing requirements of plates of different specifications and shapes, reduce the equipment downtime, and improve the production efficiency. The setting of the limiting rod 8 limits the moving track of the moving plate 2, making the moving plate 2 more stable during the adjustment process. After the adjustment is completed, the locking rod 5 is inserted into the limiting groove 4, which can firmly fix the position of the moving plate 2, avoid the displacement of the plate during the bending process, and improve the processing accuracy and operation safety.

[0026] A bending protection mechanism is provided in the bending groove 9. The bending protection mechanism includes a top plate 13, a sliding plate 12 and a spring 11. A buffer groove 10 is formed in the lower inner wall of the bending groove 9. The sliding plate 12 is slidably connected in the buffer groove 10.

And the lower surface of the sliding plate 12 is connected with the lower inner wall of the buffer groove 10 through a plurality of uniformly distributed springs 11. The top plate 13 is in a conical shape with a wider bottom and a narrower top, which can better adapt to the bending requirements of plates with different thicknesses.

[0027] It should be noted that during the bending process, the top plate 13 contacts the bottom of the bent part of the plate, preventing the plate from being scratched or deformed due to concentrated force during the bending process, reducing the damage of the plate, improving the appearance quality of the finished product. And due to the existence of the resilience of the spring 11, it can provide an effective buffering effect during the bending process, absorbing and dispersing the bending force, not only protecting the plate, but also extending the service life of the mold and reducing the maintenance and replacement frequency of the equipment.

[0028] Two symmetrically distributed mounting grooves 14 are formed in the lower surface of the connecting plate 7.
