At the same time, the assembly consisting of the telescopic rod 16, the spring 17 and the elastic ball 18 corresponding to the position of the workbench 11 also gives the steel plate a downward force. When the bending tool 15 falls to the bottom and contacts the working groove 12, a set of bending processes is completed. When the bending tool 15 leaves the working groove 12, the elastic ball 18 on the workbench 11 bounces the steel plate upward, and the elastic ball 18 at the corresponding position of the inner wall of the bending machine housing 1 contacts The steel plate is touched and buffered. At this time, the steel plate gradually stops shaking under the action of the upper and lower telescopic rods 16, springs 17 and elastic balls 18. This step reduces the shaking of the steel plate when it is placed in the working groove 12 before work by setting the telescopic rods 16, springs 17 and elastic balls 18 corresponding to the upper and lower positions. After work, the bending tool 15 leaves the working groove 12, and the upper and lower corresponding telescopic rods 16, springs 17 and elastic balls 18 squeeze the steel plate, reducing the sliding of the steel plate and the deformation of the steel plate caused by leaving the working groove 12.

By setting the wavy baffle 21, the contact area of ​​the steel plate is increased, and the deformation caused by sliding of the steel plate is reduced.

[0028] like Figure 1 and Figure 4As shown, the inner wall of the bending machine housing 1 is symmetrically fixed with a second electric push cylinder 3; the output end of the second electric push cylinder 3 is fixed with a plate brush 31; the inner wall of the plate brush 31 is fixed with multiple bristles 32; the plate brush 31 is set in a U shape; during operation, when the bending tool 15 completes a set of bending processes, the bending tool 15 is controlled to stay at the highest point by the first electric push cylinder 13, and the second electric push cylinder 3 is turned on to make the plate brush 31 clean the bending tool 15. The U-shaped setting of the plate brush 31 can more effectively clean the side wall surface of the bending tool 15. The bristles 32 on the inner wall of the plate brush 31 contact the side wall of the bending tool 15 back and forth, thereby cleaning the metal chips on the surface of the bending tool 15 and reducing the phenomenon of traces on the surface of the steel plate caused by metal chips staying on the surface of the bending tool 15 during operation.

[0029] like Figure 4 As shown, a first sponge 4 is installed at the bottom of the plate brush 31; the first sponge 4 is set in a V shape; when working, the first electric push cylinder 13 controls the bending tool 15 to stay at the highest point, and the second electric push cylinder 3 is turned on to control the plate brush 31 to move back and forth. At the same time, the first sponge 4 installed at the bottom of the plate brush 31 also cleans the working groove 12 back and forth. Through the V-shaped setting of the first sponge 4, the contact area between the first sponge 4 and the working groove 12 is increased, and the amount of metal chips on the surface of the working groove 12 is reduced. This step reduces the phenomenon that when metal chips fall into the working groove 12, the bending tool 15 presses the steel plate to the bottom of the working groove 12, causing scratches and indentations on the surface of the steel plate.

[0030] like Figure 4 As shown, a rust inhibitor tank 5 is fixedly connected to the top of the mounting plate 14; a pump head 51 is installed on the side wall of the rust inhibitor tank 5; a hose 52 is connected to the output end of the pump head 51; the hose 52 passes through the plate brush 31 and is connected to the bristles 32; when working, the liquid in the rust inhibitor tank 5 is covered on the bristles 32 by starting the pump head 51, and the bristles 32 containing the liquid in the rust inhibitor tank 5 are brought into contact with the bending tool 15 back and forth by controlling the second electric push cylinder 3, so as to soften the dirt and impurities on the bending tool 15, thereby reducing the phenomenon that the surface of the bending tool 15 is rusted due to the humid air, thereby affecting the surface smoothness of the steel plate.

[0031] like Figure 4 As shown, the rust inhibitor tank 5 is installed with a heating wire 6; by providing the heating wire 6, the liquid inside the rust inhibitor tank 5 can be heated and kept warm under low temperature conditions, thereby reducing the solidification and agglomeration of the liquid under low temperature conditions.

The second sponge 71 in the rubber plate 7 is arranged in a wave shape, which more effectively prevents the splashing of waste liquid and metal chips.

[0033] Working principle: By turning on the first electric push cylinder 13 to control the up and down movement of the bending tool 15, the part of the steel plate to be bent is placed on the working groove 12, and the other part is pressed on the elastic ball 18. The first electric push cylinder 13 is controlled to make the bending tool 15 fall. At this time, the assembly composed of the telescopic rod 16, spring 17 and elastic ball 18 on the workbench 11 will squeeze the steel plate and give it an upward force. At the same time, the assembly composed of the telescopic rod 16, spring 17 and elastic ball 18 corresponding to the position of the workbench 11 also gives the steel plate a downward force. When the bending tool 15 falls to the bottom and contacts the working groove 12 , completing a set of bending processes, when the bending tool 15 leaves the working groove 12, the elastic ball 18 on the workbench 11 bounces the steel plate upward, and the elastic ball 18 at the corresponding position of the inner wall of the bending machine housing 1 contacts the steel plate and buffers the steel plate. At this time, the steel plate gradually stops shaking under the action of the upper and lower telescopic rods 16, the spring 17 and the elastic ball 18, and the steel plate is placed on the elastic plate 2, reducing the shaking of the steel plate. One end of the steel plate contacts the inner wall of the baffle 21, reducing the phenomenon of the steel plate slipping and causing damage to the steel plate during placement. When the bending tool 15 completes a set of bending processes, through the first electric push cylinder 1 3 controls the bending tool 15 to stay at the highest point, and turns on the second electric push cylinder 3 to make the brush 31 clean the bending tool 15. When the first electric push cylinder 13 controls the bending tool 15 to stay at the highest point, the second electric push cylinder 3 is turned on to control the brush 31 to move back and forth. At the same time, the first sponge 4 installed at the bottom of the brush 31 also cleans the working groove 12 back and forth. The liquid in the rust inhibitor tank 5 is covered on the bristles 32 by starting the pump head 51. The bristles 32 containing the liquid in the rust inhibitor tank 5 are brought into contact with the bending tool 15 back and forth by controlling the second electric push cylinder 3, so as to soften the dirt and impurities on the bending tool 15 and reduce In order to prevent the bending tool 15 from rusting due to humid air and thus affecting the surface smoothness of the steel plate, an electric heating wire 6 is provided to heat and insulate the liquid inside the rust inhibitor tank 5 under low temperature conditions, thereby reducing the solidification and agglomeration of the liquid under low temperature conditions. The plate brush 31 contacts the surface of the bending tool 15 back and forth, and the waste liquid drips into the working groove 12. The second electric push cylinder 3 is turned on to control the plate brush 31 to move back and forth in the working groove 12, so that the waste liquid and impurities remaining in the working groove 12 after cleaning enter the rubber sheet 7.
