Description

Technical Field

[0001] The utility model relates to the technical field of metal bending equipment, and more specifically, to a manual bending device for metal plate processing. Background Art

[0002] Sheet metal is metal formed into thin, flat sheets by industrial methods. It can be cut and bent into a variety of shapes. Countless everyday items are made from sheet metal. Extremely thin sheets are considered foil or leaf. Sheets thicker than six millimeters are considered plate or "structural steel."

[0003] When operators process metal sheets, they often use manual bending devices to bend the metal sheets for subsequent processing and use. In actual use, although the existing manual bending devices have basic bending functions, most manual bending devices are often unable to automatically lift the metal sheets when bending the metal sheets. At this time, the operator is required to hold the metal sheets for bending, which increases the workload of the operator. In addition, since the process of bending the metal sheets by hand is dangerous, it brings inconvenience to the operator's operation, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, the utility model provides a manual bending device for metal sheet processing, comprising:

[0026] A fixed box 1, a limit slot 2 is provided at the top of the fixed box 1, vertical slots 3 are provided on both the left and right sides of the back of the fixed box 1, and a fixed plate 4 is fixedly installed at the bottom end of the back of the fixed box 1;

[0027] A lifting mechanism, which is arranged inside the vertical slot 3;

[0028] Among them, the lifting mechanism includes a lifting block 5, the number of which is two, the outer surfaces of the two lifting blocks 5 are movably connected to the inside of the vertical groove 3, a lifting plate 6 is fixedly installed in front of the bottom end of the two lifting blocks 5, and vertical rods 7 are fixedly sleeved inside the left and right sides of the lifting plate 6. The number of vertical rods 7 is two, and the bottom ends of the outer surfaces of the two vertical rods 7 are movably sleeved with fixed blocks 8, the outer surfaces of the fixed blocks 8 are fixedly connected to the inside of the fixed box 1, and the outer surfaces of the two vertical rods 7 are movably sleeved with springs 9, the top end of the spring 9 is fixedly connected to the bottom end of the lifting plate 6, and the bottom end of the spring 9 is fixedly connected to the top of the fixed block 8.

[0029] Due to the limiting effect inside the two vertical grooves 3, the two lifting blocks 5 can only move up and down. When the two lifting blocks 5 move downward along the two vertical grooves 3 at the same time, the two lifting blocks 5 will drive the lifting plate 6 to move downward. At this time, the two vertical rods 7 will move downward along the inside of the two fixed blocks 8 driven by the lifting plate 6. Due to the elastic force of the two springs 9, the overall movement of the lifting plate 6 will be provided with a good resetting effect, and the two lifting blocks 5 can play a good supporting role on the metal plate.

[0030] A jack 10 is fixedly mounted on the top of the fixing plate 4 , and a bending block 11 is fixedly mounted on the other end of the jack 10 .

[0031] When the jack 10 is in operation, the other end of the jack 10 will drive the bending block 11 to move upward. Due to the shape design of the bending block 11, the metal plate can be bent well.

[0032] Among them, round shafts 12 are fixedly installed on both sides of the top of the back side of the fixed box 1, and a bending wheel 13 is movably sleeved on the outer surface of the round shaft 12, and the front side of the bending wheel 13 is movably connected to the back side of the fixed box 1.

[0033] Since there is a gap between the two bending wheels 13, when the bending block 11 moves upward, the bending block 11 will cooperate with the two bending wheels 13 to bend the metal sheet. During this process, the two bending wheels 13 will rotate around the two circular shafts 12 respectively. At the same time, the bent metal sheet will squeeze the top of the two lifting blocks 5 so that the two lifting blocks 5 move downward along the inside of the two vertical grooves 3.

[0034] Among them, a fixing frame 14 is fixedly installed in front of the top of the fixing box 1, a driving motor 15 is fixedly installed on the top of the fixing frame 14, and a rotating shaft 16 is fixedly sleeved on the other end of the output shaft of the driving motor 15. The other end of the rotating shaft 16 passes through the top of the fixing frame 14 and extends to the inside of the fixing frame 14.

[0035] When the driving motor 15 is running, the rotating shaft 16 will rotate.

[0036] The other end of the rotating shaft 16 is fixedly sleeved with a rotating rod 17 , and the other end of the rotating rod 17 is fixedly sleeved with an extrusion shaft 18 inside.

[0037] When the rotating shaft 16 drives the rotating rod 17 to rotate, the other end of the rotating rod 17 drives the extruding shaft 18 to rotate.

[0038] Among them, the bottom end of the outer surface of the extrusion shaft 18 is movably connected with a moving block 19, the bottom end of the moving block 19 is movably connected with the top of the fixed box 1, and the bottom end of the moving block 19 is fixedly installed with a moving rod 20, and the bottom end of the moving rod 20 extends to the interior of the fixed box 1 through the limit groove 2.

[0039] When the extrusion shaft 18 rotates, the outer surface of the extrusion shaft 18 will squeeze the inside of the moving block 19 during rotation, causing the moving block 19 to move. Then the moving rod 20 will move driven by the moving block 19. Due to the limiting effect inside the limiting groove 2, the moving rod 20 will move backward along the inside of the limiting groove 2.

[0040] A push rod 21 is fixedly mounted on the bottom end of the back side of the movement rod 20 , and the other end of the push rod 21 penetrates the interior of the fixed box 1 and extends to the back side of the fixed box 1 .

[0041] When the moving rod 20 drives the push rod 21 to move backward, the other end of the push rod 21 will push the metal sheet located at the top of the two lifting blocks 5 during the backward movement. Then, the metal sheet will move to the outside of the top of the two lifting blocks 5 under the push of the push rod 21, thereby realizing the function of automatic unloading of the metal sheet.

[0042] The working principle and use process of this utility model:

[0043] First, the operator places the metal sheet on the top of the two lifting blocks 5. At this time, due to the elastic force of the two springs 9, the two lifting blocks 5 will be able to lift the metal sheet well. Then the operator starts the jack 10. At this time, the other end of the jack 10 will drive the bending block 11 to move upward. When the top of the bending block 11 contacts the bottom of the metal sheet, the metal sheet will be bent under the cooperation of the bending block 11 and the two bending wheels 13. In this process, the left and right sides of the bottom end of the metal sheet will respectively squeeze and push the top of the two lifting blocks 5 to make the two lifting blocks 5 move. Due to the limiting effect inside the two vertical grooves 3, the two lifting blocks 5 will drive the lifting plate 6 to move downward. At the same time, the lifting plate 6 will drive the two vertical rods 7 to move downward along the inside of the two fixed blocks 8. At this time, the two springs 9 will be in a compressed state. Due to the elastic force of the two springs 9, a good reset effect will be provided for the lifting plate 6 as a whole.

[0044] Then the operator starts the driving motor 15, at which time the rotating shaft 16 will drive the rotating rod 17 to rotate, and then the extrusion shaft 18 will rotate around the rotating shaft 16 as the axis driven by the rotating rod 17. At this time, the outer surface of the extrusion shaft 18 will squeeze and push the inside of the top of the moving block 19 during rotation. At this time, the moving block 19 will drive the moving rod 20 to move under the squeezing and pushing of the extrusion shaft 18. Due to the limiting effect inside the limiting groove 2, the moving block 19 will drive the moving rod 20 to move backward under the limiting inside the limiting groove 2, and then the moving rod 20 will drive the push rod 21 to move backward. At this time, the metal sheet located at the top of the two lifting blocks 5 will be pushed to the outside of the two lifting blocks 5 during the backward movement of the push rod 21, thereby realizing the function of automatic unloading of the metal sheet.
