DETAILED DESCRIPTION

[0018] 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.

[0019] For example, see Figure 1-4A construction bending machine with a protective function comprises a base 1, a fixed bracket 2 is fixedly installed on the top of the base 1, a bending machine tool body 3 is fixedly installed on the top of the inner wall of the fixed bracket 2, a support plate 4 is fixedly installed inside the base 1, a protective box 5 is fixedly installed on the top of the support plate 4, a protective mechanism 6 is arranged inside the protective box 5, a workbench 7 is fixedly installed on the top of the protective mechanism 6, a clamping assembly 8 is arranged at one end of the top of the protective box 5 close to the front, the protective mechanism 6 comprises a slide plate 61, extrusion rods 62 are fixedly installed on the left and right sides of the bottom of the slide plate 61, and buffer springs 63 are fixedly installed on the left and right sides of the bottom of the slide plate 61. Buffer boxes 64 are fixedly installed on the left and right sides of the bottom of the inner wall of the protective box 5. A pressure plate 65 is slidably connected to the inside of the buffer box 64. A rubber buffer pad 66 is fixedly installed on the bottom of the inner wall of the buffer box 64. The slide plate 61 is slidably connected to the inside of the protective box 5. The workbench 7 is fixedly installed on the top of the slide plate 61. The bottom of the buffer spring 63 is fixedly connected to the top of the buffer box 64. The top of the pressure plate 65 is fixedly connected to the bottom of the extrusion rod 62. When the bending machine is working, the workbench 7 will be impacted and move downward, thereby squeezing the slide plate 61 to move downward. The downward movement of the slide plate 61 will drive the extrusion rod 62 to move downward, and the extrusion rod 62 will drive the pressure plate 65. The downward movement causes the pressure plate 65 to squeeze the rubber buffer pad 66. The downward movement of the slide plate 61 also squeezes the buffer spring 63. Under the buffering effect of the buffer spring 63 and the rubber buffer pad 66, part of the impact force is reduced. A fixing rod 67 is fixedly installed between the two buffer boxes 64. A spherical connecting block 69 is fixedly installed at the bottom of the slide plate 61. The bottom left and right sides of the spherical connecting block 69 are hinged with connecting rods 610. A first spring plate 68 is fixedly installed at one end of the buffer box 64 close to the connecting rod 610. The plate surface of the first spring plate 68 is slidably connected to the surface of the fixing rod 67. The bottom of the connecting rod 610 is connected to the plate surface of the first spring plate 68. The top of the sliding plate 61 is hinged, and when the sliding plate 61 moves downward, it will drive the spherical connecting block 69 to move downward, thereby moving the two connecting rods 610. The connecting rods 610 will squeeze the plate surface parts of the first spring plates 68 on both sides, causing the first spring plates 68 to deform. Under the elastic action of the first spring plates 68, part of the impact force is reduced again. The setting of the protective mechanism 6 allows the bending machine to use a multi-level buffer structure when in use, which reduces the impact force on the workbench when the tool descends, thereby increasing the service life of the bending machine. The multi-level buffer structure allows the bending machine to be used multiple times, thereby increasing the environmental protection performance of the bending machine and improving the practicability of the bending machine.

[0020] When in use, the bending machine will cause the workbench 7 to move downward due to impact, thereby squeezing the slide plate 61 downward. The downward movement of the slide plate 61 will drive the squeezing rod 62 to move downward, and the squeezing rod 62 will drive the pressure plate 65 to move downward, so that the pressure plate 65 squeezes the rubber buffer pad 66. The downward movement of the slide plate 61 will also squeeze the buffer spring 63. Under the buffering effect of the buffer spring 63 and the rubber buffer pad 66, part of the impact force is reduced. When the slide plate 61 moves downward, it will drive the spherical connecting block 69 to move downward, thereby moving the two connecting rods 610. The connecting rods 610 will squeeze the plate surface part of the first spring plate 68 on both sides, causing the first spring plate 68 to deform. Under the elastic action of the first spring plate 68, part of the impact force is reduced again.

There are two fixed plates 81, and the two fixed plates 81 are fixedly installed on the left and right sides of the top of the protective box 5, respectively. One end of the first electric telescopic rod 82 near the slider 83 is fixedly connected to one end of the slider 83 near the fixed plate 81. Starting the first electric telescopic rod 82 makes the first electric telescopic rod 82 extend or shorten, thereby driving the slider 83 to slide left and right along the top of the protective box 5. A second electric telescopic rod 86 is fixedly installed on the top of the slider 83, and a mounting plate 84 is fixedly installed on the top of the second electric telescopic rod 86. A second spring plate 85 is fixedly installed on the top of the inner wall of the mounting plate 84. The plate surface portion of the second spring plate 85 is slidably connected to the inside of the mounting plate 84, and the slider 83 is located on the front side of the workbench 7. The plate surface portion of the second spring plate 85 is pulled upward to slide, and the building board to be processed is placed inside the mounting plate 84, and the second spring plate 85 is released. Under the elastic action of the second spring plate 85, the plate surface portion of the second spring plate 85 moves downward, and the building board to be processed is clamped, and the second electric telescopic rod 86 is started to adjust the position of the building board to facilitate processing by the staff. The setting of the clamping assembly 8 allows the clamp of the bending machine to be adjusted according to the shape or size of the building board to be processed, so that different building boards can be clamped to improve the working efficiency of the bending machine. The simple mechanical structure is adopted to simplify the operating steps of the staff, so that the working efficiency of the bending machine is improved.

[0022] When in use, on the basis of Example 1, the first electric telescopic rod 82 is started to extend or shorten the first electric telescopic rod 82, thereby driving the slider 83 to slide left and right along the top of the protective box 5, pulling the board surface part of the second spring plate 85 to slide upward, and placing the building board to be processed inside the mounting plate 84, loosening the second spring plate 85, and under the elastic action of the second spring plate 85, the board surface part of the second spring plate 85 moves downward, and the building board to be processed is clamped, and the second electric telescopic rod 86 is started to adjust the position of the building board to facilitate processing by the staff.
