Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a bending mechanism of a bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls, and the operation is also very simple.

[0003] The current bending machines still have the following shortcomings in actual use:

[0004] 1. The bending machine will have a bending die seat that matches the bending knife, and the bending die seat is often set in a V-shape. When bending, friction will occur between the plate and the bending die seat, causing the debris on the surface of the plate to easily fall into the V-shaped groove of the bending die seat, thereby affecting the subsequent bending effect;

[0005] 2. Due to the large size and mass of the bending die base, when selecting the bending die groove on the bending die base according to the bending requirements, it is necessary to manually lift the two ends of the bending die base and turn the bending die base over to select the bending die groove, which increases the workload of the staff. Utility Model Content

[0006] The purpose of the utility model is to provide a bending mechanism of a bending machine to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-4 As shown, a bending mechanism of a bending machine includes a bending machine body 1, a bending die base 2 is arranged at the bottom of the inner side of the surface of the bending machine body 1, and fixed rods 3 are fixedly connected to both sides of the bending die base 2, electric push rods 4 are fixed to both sides of the bottom of the surface of the bending machine body 1, the output shaft of the electric push rod 4 is bolted to a folding plate 5, both ends of the folding plate 5 are fixedly connected to a top plate 6, and the top of the top plate 6 is fixedly connected to a support block 7, a motor 11 is arranged on the right side of the bending machine body 1, a screw 12 is bolted to the output shaft of the motor 11, and the other end of the screw 12 is rotatably connected to the left side of the surface of the bending machine body 1, a screw sleeve 13 is threadedly connected to the surface of the screw sleeve 13, and a fixed pipe 14 is fixed to the surface of the screw sleeve 13, and the other end of the fixed pipe 14 is connected to a dust suction head 15, and a dust suction structure 16 for adsorbing debris is arranged on the left side of the bending machine body 1 and connected to the fixed pipe 14.

[0025] The dust collecting structure 16 includes a dust collecting box 161, a dust collecting machine 162 and a connecting pipe 163. The dust collecting box 161 is fixed on the left side of the bending machine body 1, and the dust collecting machine 162 is arranged on the top of the dust collecting box 161. The suction end of the dust collecting machine 162 is connected to the dust collecting box 161. The two ends of the connecting pipe 163 are respectively connected to the dust collecting box 161 and the fixed pipe 14. In this way, when the screw sleeve 13 drives the fixed pipe 14 and the dust collecting head 15 to move inside the bending die base 2, the dust collecting box 161 can be sucked by the screw sleeve 13. Start the vacuum cleaner 162 to generate negative pressure inside the dust box 161, and then absorb the debris and other impurities inside the bending die base 2 through the vacuum head 15, and discharge them into the dust box 161 through the connecting pipe 163. The connecting pipe 163 is a retractable hose, and its extension length is greater than the length of the screw 12. In this way, as the screw sleeve 13 and the fixed pipe 14 move, the connecting pipe 163 will be driven to retract and lengthen, thereby avoiding the phenomenon of the connecting pipe 163 being broken.

[0026] A limiting groove 18 is provided on the rear wall on the inner side of the surface of the bending machine body 1, and the back side of the screw sleeve 13 is fixedly connected to the limiting block 17, and the surface of the limiting block 17 is slidably connected to the inside of the limiting groove 18, so that the screw sleeve 13 can be auxiliary limited to facilitate its left and right movement.

[0027] Slide grooves 9 are provided at the front and rear sides of both sides of the bending machine body 1, and sliders 10 are fixedly connected to the front and rear sides of the top plate 6 close to the bending machine body 1. The surface of the slider 10 is slidably connected to the inside of the slide groove 9, so that the top plate 6 can be auxiliary supported and its stability during movement can be maintained.

[0028] Support plates 8 are fixedly connected to both sides of the bending machine body 1, and the surface of the folding plate 5 is movably connected to the inside of the support plate 8, so that the folding plate 5 can be auxiliary supported to facilitate its up and down movement.

[0029] Working principle: After bending the plate many times, in order to maintain the accuracy of subsequent bending, before each use, the motor 11 can be started, and the screw rod 12 can be driven to rotate, while driving the screw sleeve 13 to move to the left, and driving the fixed tube 14 and the dust suction head 15 to move along the inner side of the bending die base 2. During the movement, the dust suction structure 16 can be started so that the dust suction head 15 can adsorb the debris and impurities on the inner side of the bending die base 2. When the V-groove die of the bending die base 2 is switched, the limit of the bending die base 2 can be cancelled, and then the electric push rod 4 is started, and the folding plate 5 and the top plate 6 are driven to move upward, so that the top of the support block 7 is aligned with the surface of the fixed rod 3, thereby lifting the bending die base 2. After that, the staff can drive the bending die base 2 to rotate to the required V-groove surface, and restart the electric push rod 4, thereby driving the folding plate 5, the top plate 6 and the support block 7 back to the starting position, and finally fix the bending die base 2 again.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
