[0003] When the existing metal plate bending machine is used for bending and processing plates, the plates need to be manually lifted and fed from both sides, and then cooperate with the bending machine to complete the bending and processing of the plates. Due to the different widths of the plates, when the width of the bottom support frame is used for supporting the plates, it cannot be adjusted adaptively according to the width of the plates, so that the width of the support frame is relatively large, and one side of the plate support cannot control the plate, thus affecting the feeding operation of the plate.

[0026] Machine body 1, a lower template 2 is arranged on the workbench of the machine body 1, and a folding bending knife 3 is arranged at the driving end of the machine body 1;

[0027] Guide rail 5, the guide rail 5 is arranged on the front of the machine body 1, and a support assembly 6 is slidably connected to the outside of the guide rail 5, and a scissor mechanism 7 is hinged between adjacent support assemblies 6;

[0028] The support assembly 6 includes a slider 61 which is slidably connected to the outside of the guide rail 5. An articulated shaft 62 is slidably connected inside the slider 61. A hinge seat 63 is fixedly connected to the front surface of the slider 61. The top of the hinge seat 63 is hinged with an articulated rod 64. A guide frame 67 is fixedly connected to the upper surface of the articulated rod 64. A guide roller 68 is rotatably connected inside the guide frame 67. Through the setting of this structure, the auxiliary support for the metal plate can be completed. And through the contact of the guide roller 68, the friction with the plate can be reduced, improving the smoothness of the plate displacement. At the same time, the setting of this structure facilitates the auxiliary support for the plate, and the sliding connection setting facilitates the flexible adjustment of its support width.

[0029] Further, two groups of guide rails 5 are provided, and the two groups of guide rails 5 are symmetrically distributed on the upper and lower sides of the slider 61. Articulated shafts 62 are provided at the four corners of the articulated shaft 62, and the articulated shaft 62 is in a T-shaped structure. A guide groove adapted to the articulated shaft 62 is correspondingly opened on the front surface of the slider 61. One end of a scissor mechanism 7 is rotatably connected to the outside of the articulated shaft 62. The scissor mechanism 7 is in a cross-shaped structure. A support rod 65 is hinged inside the hinge seat 63. The other end of the support rod 65 is inserted into the inside of the articulated rod 64 through a limit pin 66. The articulated connection of the scissor mechanism 7 can realize the mutual connection between adjacent support assemblies 6, so that when one support assembly 6 is pulled in position, the next support assembly 6 can be driven to displace through the articulation of the scissor mechanism 7.

[0030] Further, the top horizontal plane of the guide roller 68 is at the same horizontal plane as the top horizontal plane of the lower template 2. A limit card slot is opened on one side of the articulated rod 64 corresponding to the hinge seat 63, which is convenient for the stable engagement of the folding and storage of the articulated rod 64.

[0031] Further, it also includes a positioning assembly 4. The positioning assembly 4 includes a positioning rod 41 and a positioning block 44. A limit plate 42 is fixedly connected to one end of the positioning rod 41. A support frame 43 is sleeved outside the positioning rod 41. The positioning block 44 is fixedly connected to the outer wall of the machine body 1. A positioning pin 45 is inserted into the inside of the positioning block 44 and the positioning rod 41. Through the setting of this structure, the width of the bent part of the plate can be assisted in being limited through the limit plate 42, and at the same time, it plays a good guiding and limiting role to ensure the smoothness of the metal plate.

[0032] Further, positioning rods 41 are fixedly connected to both ends of the limit plate 42. Adjustment holes are opened on the positioning rods 41. A positioning hole is opened at the center of the positioning block 44, and the size of the positioning hole is the same as that of the adjustment hole. And a positioning pin 45 penetrates through the adjustment hole. Through the penetration of the adjustment holes at different positions, the flexible adjustment of different widths is realized. The support frame 43 is fixedly connected to the outer wall of the machine body 1. The positioning rod 41 is slidably connected above the support frame 43. The positioning block 44 is located above the positioning rod 41.

[0033] Working principle: When the utility model is in use, first place the plate to be processed above the guiding roller 68, and limit the position of the limiting plate 42 according to its bending width. Then, when one side of the metal plate is pushed into contact with the limiting plate 42, the bending of the metal plate is completed by the downward pressure of the bending knife 3.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
