[0023] See also Figure 1-5 As shown, the utility model proposes a bending auxiliary device for sheet metal processing, including a workbench 3 and a bending mechanism 1 assembled on the top of the workbench 3, and a positioning mechanism 2 assembled on one side of the workbench 3, a bending seat 301 is fixedly installed on one side of the workbench 3, the bending mechanism 1 includes a fixed frame 101 fixedly installed on the top of the workbench 3, a movable plate 102 is slidably installed at the bottom of the fixed frame 101, a bending knife 103 used in conjunction with the bending seat 301 is rotatably installed at the bottom of the movable plate 102, a roller 108 is rotatably installed on one side of the bending knife 103, a pressing plate 104 is slidably installed at the bottom of the movable plate 102 and located at the bottom of the bending knife 103, a through groove 107 is opened on the pressing plate 104 for flipping the bending knife 103, and the positioning mechanism 2 includes a positioning frame 201 slidably installed on the outside of the workbench 3, and a scale line 203 is engraved on the front end of the positioning frame 201.

[0024] Based on the arrangement of the above structure, the bending auxiliary device for sheet metal processing is composed of a bending mechanism 1, a positioning mechanism 2 and a workbench 3, wherein the workbench 3 can conveniently support the sheet metal, the positioning mechanism 2 can conveniently position the sheet metal to the required bending length, and the bending mechanism 1 can conveniently perform bending operations on the sheet metal. Specifically, in the working process, by observing the value on the scale line 203 corresponding to the bending seat 301, the positioning frame 201 is pulled to the specified length, and the sheet metal is placed on the workbench 3, so that one end of the sheet metal is against the inner side of the positioning frame 201, so that the bending length of the sheet metal can be conveniently positioned according to the preset length of the positioning frame 201, and by pushing the movable plate 102 to move downward, the pressing plate 104 can be pressed on the sheet metal, so that the sheet metal can be fixed to avoid displacement of the sheet metal during bending. The movable plate 102 moves downward, which can cause the pressure plate 104 to squeeze the roller 108. Through the rolling action of the roller 108, the bending knife 103 can be turned over, and one end of the bending knife 103 can be extended downward from the through groove 107, which can cooperate with the supporting action of the bending seat 301, so that the bending knife 103 can bend the sheet metal part. After the bending is completed, by driving the movable plate 102 to move upward, the pressure plate 104 can be separated from the sheet metal part, and at the same time, the pressure plate 104 can release the squeezing of the roller 108, so that the bending knife 103 can be turned over and reset, and one end of the bending knife 103 can be retracted into the through groove 107, so that the bending knife 103 can be placed between the movable plate 102 and the pressure plate 104, which can effectively protect the bending knife 103 and avoid the bending knife 103 from colliding with external objects when not in use, thereby improving the safety effect.

[0025] Furthermore, a hydraulic push rod 106 is fixedly installed on the top of the fixed frame 101, and the output end of the hydraulic push rod 106 passes through the fixed frame 101 and is fixedly connected to the movable plate 102. The hydraulic push rod 106 can provide power for the movable plate 102, and can conveniently drive the movable plate 102 to move up and down.

[0026] Further, two movable columns 105 penetrating the fixed frame 101 are fixedly installed on the top of the movable plate 102, and a support frame 302 is fixedly installed on the bottom of the workbench 3. The movable columns 105 can slide up and down along the fixed frame 101, so that the movable plate 102 will not shake when moving up and down.

[0027] Furthermore, the movable plate 102 and the bending knife 103 are rotatably mounted via a movable seat 5, and a return spring 4 is hingedly mounted between the bottom of the movable plate 102 and one side of the bending knife 103. The bending knife 103 can be turned over by the movable seat 5, and the return spring 4 can be used to pull the bending knife 103 to turn over and reset.

[0028] Furthermore, a plurality of slide posts 109 arranged in a matrix are fixedly mounted on the top of the pressing plate 104, and the slide posts 109 penetrate the movable plate 102. The slide posts 109 can slide up and down along the movable plate 102, so that the pressing plate 104 can move up and down stably without being skewed.

[0029] Furthermore, the positioning frame 201 is fixed to the workbench 3 via a fixing knob 204, and a handle 202 is fixedly mounted on one side of the positioning frame 201. The positioning frame 201 and the workbench 3 can be conveniently fixed by turning the fixing knob 204 after the distance is adjusted, so as to avoid the positioning frame 201 from accidentally sliding. By holding the handle 202, the positioning frame 201 can be conveniently operated to slide left and right, so as to adjust the bending length according to the bending requirements.
