DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0021] Reference Figure 1-Figure 3 A bending machine for door leaf processing includes a machine base 1, a placement groove 17 is opened on the machine base 1, two brackets 13 are fixedly arranged on the machine base 1, a hydraulic cylinder is installed on each bracket 13, and the driving ends of the two hydraulic cylinders are respectively fixedly connected with a fixed rod 8 and a T-shaped rod 9, a sliding rod 4 is connected to the machine base 1 through a first spring 5, one end of the sliding rod 4 is fixedly connected with a positioning plate 3, and an extrusion assembly is arranged on the T-shaped rod 9, and the extrusion assembly includes an extrusion rod 7 slidably arranged on the T-shaped rod 9, a second spring 6 is sleeved on the extrusion rod 7, one end of the second spring 6 is fixedly connected to the extrusion rod 7, and the other end of the second spring 6 is fixedly connected to the T-shaped rod 9, the cross-section of the sliding rod 4 is arranged in a right-angle trapezoidal shape, and the lower end of the extrusion rod 7 is in contact with the inclined surface of the sliding rod 4.

[0022] The lower end of the fixing rod 8 is connected to a mounting plate 12 with a T-shaped cross-section through a bolt 2. A threaded groove for connecting the bolt 2 is opened on the fixing rod 8. A bending block is fixedly arranged under the mounting plate 12. One end of the bolt 2 is passed through the mounting plate 12 and threadedly connected to the threaded groove, so that the mounting plate 12 and the fixing rod 8 can be firmly connected together. When the bending block is damaged, it is convenient to replace it in time. The lower end of the T-shaped rod 9 is fixedly connected to a pressing plate 10, and the lower surface of the pressing plate 10 is fixedly connected to a rubber pad 11. When the rubber pad 11 at the bottom of the pressing plate 10 fits with the surface of the door leaf to be processed, the door leaf to be processed can be prevented from warping during the bending process.

[0023] An ear plate 16 is fixedly connected to the surface of one side of the machine base 1, and a push rod 14 with an L-shaped cross-section is slidably connected to the ear plate 16. A push plate 15 is fixedly connected to one end of the push rod 14. A slide groove 18 is provided on the lower surface of the placement groove 17. The slide groove 18 is used to limit the movement trajectory of the push rod 14. When a thinner door leaf to be processed is processed and the door leaf to be processed is located directly above the placement groove 17 as a whole, one end of the push rod 14 can be placed in the slide groove 18. At this time, the bottom surface of the push plate 15 and the lower surface of the placement groove 17 are fitted together, and then the push rod 14 is pushed. During the movement of the push rod 14 inside the slide groove 18, the push plate 15 can push the door leaf to be processed to move together, thereby facilitating the end position of the processed door leaf that needs to be bent to be pushed to directly below the mounting plate 12 and the bending block.

[0024] The bottom surface of the base 1 is fixedly connected with a support pad, and the surface of the support pad is provided with anti-skid patterns, which can increase the friction between the base 1 and the ground to prevent relative sliding between the base 1 and the ground, which is beneficial to improving the stability of the base 1.

[0025] In the utility model, when in use, the door leaf to be processed is placed in the placement groove 17, and then the door leaf to be processed is pushed until the end position of the door leaf to be processed needs to be bent, and then moved to the bottom of the mounting plate 12 and the bending block, and then a hydraulic cylinder drives the T-shaped rod 9 to move downward, thereby driving the pressing plate 10 and the extrusion rod 7 to move downward together. The stiffness coefficient of the second spring 6 is greater than the stiffness coefficient of the first spring 5. During the downward movement of the extrusion rod 7, it will move against the inclined surface of the slide bar 4, and the slide bar 4 and the machine base 1 will slide relative to each other. Since one end of the first spring 5 is fixedly connected to the slide bar 4, and the other end is fixedly connected to the machine base 1, the first spring 5 is deformed until one side surface of the door leaf to be processed and the fixed The surface of the positioning plate 3 is in close contact, and the other side surface of the door leaf to be processed is in close contact with the inner wall of one side of the placement groove 17, so that the door leaf to be processed is clamped and fixed. After that, when the extrusion rod 7 continues to move downward with the T-shaped rod 9, the extrusion rod 7 will slide relative to the T-shaped rod 9 until the rubber pad 11 is in close contact with the surface of the door leaf to be processed, and another hydraulic cylinder drives the fixing rod 8 to move downward, thereby driving the mounting plate 12 and the bending block to move downward together. The process of the bending block moving downward can be used to bend the door leaf to be processed. According to actual usage, metal door leaves of different widths can be better fixed, and then door leaves of different widths can be bent. The use of the bending machine has few limitations, which is conducive to the processing of the door leaf.

[0026] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
