In a specific implementation, the support plate 110 is L-shaped, which can support the lifting member 120. The plate-shaped sheet metal part is placed on the upper surface of the base 100. By starting the lifting member 120, its movable end drives the bending head 130 to move downward, which is beneficial to the bending process of the sheet metal part, and the bending head 130 will enter the notch 140.

It should be noted that the telescopic member 121 can be a cylinder, an electric cylinder or a hydraulic cylinder.

[0028] See also Figure 1-Figure 4 The positioning assembly 200 includes a motor 210 and two transmission members 220. The motor 210 is installed in the support plate 110, and the output shaft of the motor 210 is transmission-connected to the two transmission members 220. The two transmission members 220 are both rotatably installed in the support plate 110, and one end of the two transmission members 220 is connected to a screw rod 230. The surfaces of the two screw rods 230 are threadedly sleeved with positioning blocks 240, and the positioning blocks 240 are in contact with the surface of the support plate 110. In the specific implementation, the plate-shaped sheet metal part is placed on the base 100, and the motor 210 is started so that its output shaft drives the two transmission members 220 to rotate, thereby driving the screw rod 230 connected to the transmission member 220 to rotate, so that the positioning block 240 can move downward along the surface of the support plate 110, reducing the possibility that the moving trajectory of the positioning block 240 will deviate during the movement process, and the positioning block 240 will press and fix the two ends of the sheet metal part, reducing the possibility that the position of the sheet metal part will deviate when the sheet metal part is bent.

[0029] In this embodiment, a placement groove 111 is provided on the surface of the support plate 110, and the motor 210 is installed in the placement groove 111.

In a specific implementation, the first synchronous pulley 211, the toothed belt 250 and the two transmission members 220 are arranged in the cavity 112, so as to reduce the possibility of damage to the first synchronous pulley 211, the toothed belt 250 and the two transmission members 220 due to external influences.

[0030] The transmission member 220 includes a connecting rod 221 and a second synchronous pulley 222. The connecting rod 221 is rotatably installed in the support plate 110, and the connecting rod 221 is respectively connected to the second synchronous pulley 222 and the screw rod 230.

In the specific implementation, by starting the motor 210, its output shaft drives the first synchronous pulley 211 to rotate, and the first synchronous pulley 211 can drive the two second synchronous pulleys 222 to rotate through the toothed belt 250, thereby driving the two connecting rods 221 and the two screw rods 230 to rotate, so that the moving block 241 can move along the inner wall of the slide groove 113, and the moving block 241 can move along the inner wall of the slide groove 113. In order to ensure the stability of the moving block 241 when moving, the screw rod 230 is set in the slide groove 113, which is conducive to the compact connection between the components of the device; the notch 140 is located between the two positioning blocks 240, and the lower surfaces of the two positioning blocks 240 are connected to elastic pads 242. In the specific implementation, the elastic pads 242 are set on the lower surfaces of the positioning blocks 240 to make the elastic pads 242 contact with the sheet metal parts, thereby reducing the possibility of wear caused by the contact between the sheet metal parts and the positioning blocks 240. It should be noted that the elastic pads 242 can be made of rubber or silicone.

[0032] Specifically, the working principle of the device for processing sheet metal bending is as follows: when in use, a plate-shaped sheet metal part is placed on the surface of the base 100, and the motor 210 in the placement groove 111 is started, so that its output shaft drives the first synchronous pulley 211 to rotate, and the first synchronous pulley 211 can drive the two second synchronous pulleys 222 to rotate through the toothed belt 250, thereby driving the two connecting rods 221 and the two screw rods 230 to rotate, and the moving block 241 on the surface of the screw rod 230 will move downward along the inner wall of the slide groove 113, lowering the moving block 2 During the movement, the moving track may be offset, and the moving block 241 may drive the positioning block 240 to move downward, so that it presses the upper surface of the sheet metal, thereby reducing the possibility of the position of the sheet metal being easily offset during the bending process. By starting the telescopic member 121 on the surface of the support plate 110, the movable end of the telescopic member 121 drives the connecting plate 122 to move, thereby driving the bending head 130 to move downward, which is beneficial to the bending process of the sheet metal, and the bending head 130 will enter the notch 140.
