[0026] The bending mechanism 3 includes a vertical plate 20 arranged at one end of the telescopic support 4 away from the fixed support 1. The vertical plate 20 is vertically arranged in the middle of the lower surface of the fixed support 1. The lower end of the vertical plate 20 is rotatably connected to the bending plate 19. The vertical plate 20 is connected to the side of the bending plate 19 close to the fixed support 1. Therefore, under the action of the self-weight of the bending plate 19, the upper side of the bending plate 19 is in a state of separation of the two sides, and after the bending plate 19 is fully opened, the upper end of the bending plate 19 is lower than the upper surface of the telescopic support 4, so that the stainless steel plate It can fall freely on the telescopic support 4 and the fixed support 1 without interfering with the bending plate 19, and a U-shaped guard frame 21 is set on the upper surface of the telescopic support 4 at one end away from the fixed support 1. The U-shaped guard frame 21 is a U-shaped structure set in a front-to-back direction and opened downward, so the stainless steel plate can be inserted into the U-shaped guard frame 21. Therefore, when the bending plate 19 is rotated to a vertical state, the bending plate 19 and the U-shaped guard frame 21 will cooperate with each other to bend the edge of the stainless steel plate by ninety degrees.

[0027] In one case of the present embodiment, a limit plate 9 is provided at one end of the first guide slide bar 6 close to the fixed support 1, a tension spring 8 is provided between the limit plate 9 and the second fixed block 7, and a spacing adjustment component 15 for adjusting the spacing between the fixed support 1 and the telescopic support 4 is provided in the middle of the fixed support 1. The spacing adjustment component 15 includes a mounting cross plate 10 fixedly connected to the end of the fixed support 1, a displacement screw 11 is rotatably connected to the middle of the mounting cross plate 10, and the displacement screw 11 is threadedly connected to the middle of the first push plate 13, the end of the first push plate 13 is rotatably connected to one end of the first push rod 14, and the other end of the first push rod 14 is rotatably connected to the side of the first guide slide bar 6.

A mounting cross plate 10 arranged in a left-right direction is provided on the front and rear sides of the lower surface of the fixed support platform 1, and the middle part of the mounting cross plate 10 is rotatably connected to the front and rear ends of the displacement screw 11 arranged in the front and rear directions, and the front and rear sides of the displacement screw 11 are threadedly connected to the first push plate 13 arranged in the left and right directions, and because the threads on the front and rear sides of the displacement screw 11 are rotated in opposite directions, when the displacement screw 11 rotates, the two first push plates 13 move closer to each other or away from each other, and the first push rod 14 is deflected toward the side away from the fixed support platform 1, so that when the first push plates 13 are separated from each other, the first push rod 14 pushes the first guide slide bar 6 to move in the direction away from the fixed support platform 1, so that the two telescopic supports 4 can move closer to each other or away from each other synchronously.

[0028] In one case of the present embodiment, a support seat 24 is provided in the middle of the lower surface of the telescopic support platform 4, and telescopic slide rods 25 arranged in left and right directions are slidably connected to the upper and lower sides of the support seat 24, and a baffle 26 is fixedly connected to the end of the telescopic slide rod 25 close to the fixed support platform 1, and a vertically arranged push block 23 is provided at the end of the telescopic slide rod 25 away from the fixed support platform 1, and the lower end of the push block 23 is rotatably connected to one end of the second push rod 22, and the other end of the second push rod 22 is rotatably connected to the bending plate 19, and an ejection assembly 34 for pushing the telescopic slide rod 25 to move left and right is provided on the side of the telescopic support platform 4 close to the fixed support platform 1. The ejection assembly 34 includes a rotating shaft 28 rotatably connected to the telescopic support platform 4, and the rotating shaft 28 is vertically arranged in the middle of the lower surface of the telescopic support platform 4. A cam 27 cooperating with the baffle 26 is provided at the lower end of the rotating shaft 28. According to the attached Figure 2The position description shows that the cam 27 extends to the rear side, and a fixing plate 30 is provided on the side of the rotating shaft 28 close to the fixed support platform 1. The fixing plate 30 is vertically arranged and fixed on the front and rear sides of the lower surface of the telescopic support platform 4. The fixing plate 30 is fixedly connected to the limiting slide bar 31 arranged in the front and rear directions. The middle part of the limiting slide bar 31 is slidably connected with a sliding bar 32. A rack 33 is provided on the side of the sliding bar 32 away from the fixed support platform 1. A driven gear 29 meshing with the rack 33 is provided in the middle part of the rotating shaft 28. Lifting cylinders 37 are provided on both sides of the lower surface of the platform 1. The piston rod of the lifting cylinder 37 is fixedly connected to a second push plate 36 arranged in a left-right direction. The left and right ends of the second push plate 36 are slidably connected to a second guide slide bar 35 arranged in a left-right direction. The end of the second guide slide bar 35 away from the fixed support platform 1 is fixedly connected to the sliding bar 32. Through the relative sliding of the second guide slide bar 35 and the second push plate 36, after the telescopic support platform 4 moves left and right, the lifting cylinder 37 can always drive the rack 33 to move. The two sides of the second push plate 36 are slidably connected to the guide column 12, and a through hole 38 is provided in the middle of the second push plate 36. The middle of the displacement screw rod 11 passes through the connecting through hole 38.

[0029] During the implementation of this embodiment, the fixed support platform 1 is placed horizontally, and the lifting cylinder 37 is started. The piston rod of the lifting cylinder 37 extends forward, so that the second push plate 36 moves forward. At this time, the second guide slide bar 35 slides along the second push plate 36, and the second guide slide bar 35 drives the sliding bar 32 to move forward. At this time, the cam 27 rotates to the front and rear direction, and at this time, the upper end of the bending plate 19 opens under the action of gravity, and the drive motor 16 is started. The drive motor 16 rotates the displacement screw 11 through gear transmission. At this time, the telescopic support platforms 4 on the left and right sides move left and right, thereby adjusting the spacing between the telescopic support platforms 4, so that the spacing between the U-shaped guard frames 21 on the left and right sides is located at the position where the stainless steel plate needs to be bent. At this time, the entire device has completed the preparation work.

[0030] Insert the stainless steel plate into the U-shaped baffles 21 on the left and right sides from left to right, move the position of the stainless steel plate left and right, so that the position where the stainless steel plate needs to be bent is moved to the bottom of the U-shaped baffle 21, and start the lifting cylinder 37 in reverse. The piston rod of the lifting cylinder 37 contracts, so that the second push plate 36 rotates the cam 27 through the cooperation of the driven gear 29 and the rack 33. The cam 27 pushes the baffle 26 to move away from the fixed support platform 1. At this time, the push block 23 pushes the bending plate 19 to rotate to a vertical state through the second push rod 22. At this time, the cooperation between the bending plate 19 and the U-shaped baffle 21 completes the bending process on both sides of the stainless steel plate.

[0031] The present invention is applicable to a plate bending machine for processing stainless steel stoves. The bending plates 19 on both sides can be bent simultaneously through the cooperation of the rack 33 and the driven gear 29, and the spacing between the telescopic supports 4 on both sides is adjustable, so that the bending machine can process stoves of different widths.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
