[0028] In this embodiment, the sliding plate 20 is located above the lower pressure plate 11, and a sliding groove matching the sliding plate 20 is opened at the top of the lower pressure plate 11. The sliding plate 20 and the sliding groove are located in the same straight line plane, and an inclined edge matching the diagonal support plate is opened on the side of the lower pressure plate 11 facing the diagonal support plate.

[0029] In this embodiment, one end of the lower pressure plate 11 extends into the fixed frame 3, and a second fixed column 24 is fixedly installed at the top of the lower pressure plate 11, and a first fixed plate 25 is fixedly installed on the outer side of the second fixed column 24.

The top of the second fixed column 24 is fixedly connected to the side of the adjustment plate 15.

[0030] In this embodiment, a movable plate 7 is fixedly installed on the top of the first fixed column 21, an adjusting column 17 is fixedly installed on the top of the movable plate 7, an inclined plate 18 is fixedly installed on the other end of the adjusting plate 15, the movable plate 7 is in movably contact with the inclined plate 18, a piston column 32 is movably installed inside the telescopic cylinder 14, a tooth block portion is provided on the outer side of the piston column 32, a third fixed column 33 is fixedly installed inside the fixed frame 3, and the piston column 32 is located on the outer side of the third fixed column 33.

[0031] In this embodiment, the synchronous limiting mechanism includes an adjusting gear 28, an adjusting cylinder 29 and a fourth fixed column 48. The adjusting gear 28 is meshed and connected with the tooth block portion on the outer side of the piston column 32. A piston rod 35 is movably installed inside the adjusting cylinder 29. A limiting block 31 is fixedly installed at one end of the piston rod 35. The limiting block 31 contacts the adjusting gear 28. The other end of the piston rod 35 contacts the adjusting column 17. A third compression spring 34 and a limiting column 30 are movably installed on the outer side of the fourth fixed column 48. The limiting column 30 is movably in contact with the end of the piston rod 35 and the end of the adjusting column 17 respectively.

[0032] In this embodiment, the fourth fixed column 48 is fixedly installed above the adjusting cylinder 29, and a first bevel is provided on both sides of the top of the adjusting column 17, and a second bevel matching the first bevel is provided at the end of the piston rod 35. The third compression spring 34 is located above the limiting column 30, and the limiting column 30 is L-shaped. A third bevel matching the first bevel is provided on both sides of the bottom end of the limiting column 30.

[0033] When the moving plate 7 does not start to work, the initial position of the moving plate 7 is flush with the height of the inclined plate 18 .

[0034] The top end of the piston plate 23 is fixedly connected to the bottom end of the movable plate 7. When the movable plate 7 moves, the height of the cutting knife mounting bracket 19 can be adjusted by the piston plate 23, that is, the height of the cutting knife can be adjusted, so that the cutting knife can cut metal parts 4 of different thicknesses.

[0035] The metal body 6 is located below the lower pressure plate 11 under the cooperation of the conveyor belt and the inclined block 47, and lifts up the lower pressure plate 11. The lower pressure plate 11 will drive the second fixed column 24 to move upward, and compress the second compression spring 26 through the first fixed plate 25. When the second fixed column 24 moves upward, it will drive the adjustment plate 15 to move upward. When the adjustment plate 15 moves upward, it will drive the piston column 32 to move upward in the telescopic cylinder 14, and drive the adjustment gear 28 to rotate. Through the cooperation of the working motor 9, the lead screw 10 and the threaded block 16, the connecting frame 8 is driven to move toward one side of the metal body 6. The connecting frame 8 can drive the movable plate 7 to move together through the first fixed column 21. When the movable plate 7 moves toward one side of the metal body 6, it can move toward the bottom end of the adjustment plate 15 through the action of the inclined plate 18, and move against the bottom end wall of the adjustment plate 15. After the movable plate 7 moves and before the inclined plate 18 contacts, the adjusting column 17 at the top of the movable plate 7 will drive the piston rod 35 to move to one side in the adjusting cylinder 29, and drive the limit block 31 to move toward the adjusting gear 28 and slowly contact the adjusting gear 28. As the movable plate 7 moves and contacts the bevel 18, the movable plate 7 will move downward through the bevel 18, showing an inclined line movement, so that the adjusting column 17 will slowly disengage from the piston rod 35, until the adjusting column 17 is disengaged from the piston rod 35, the limit column 30 will contact the piston rod 35 under the action of the third compression spring 34, and make the piston rod 35 unable to move in the adjusting cylinder 29, and at the same time the limit block 31 will fix the adjusting gear 28, so that the adjusting plate 15 will be kept in a fixed state by the movable column 32, that is, the height at which the lower pressure plate 11 is lifted, so that the movable plate 7 will not cause the adjusting plate 15 to move when it moves through the bevel 18; A squeezing spring is provided in the adjusting cylinder. The squeezing spring is located on the outside of the piston rod 35 and close to one side of the limit block 31. When the piston rod 35 is squeezed by the adjusting column 17, the squeezing spring will contract. When the piston rod 35 is separated from the limit column 30, the piston rod 35 will return to its original position under the action of the squeezing spring.

[0036] When the movable plate 7 is pressed down by the adjusting plate 15, the movable plate 7 will drive the sliding plate 20 to contact the sliding groove in the lower pressure plate 11 through the first fixed column 21, and fix the lower pressure plate 11 so that the lower pressure plate 11 is fixed on the upper surface of the metal body 6. At the same time, when the movable plate 7 moves downward, the cutting knife mounting frame 19 will be driven to move together through the piston plate 23. The descending distance of the movable plate 7 makes the descending distance of the cutting knife mounting frame 19 and the sliding plate 20 equal, so that the cutting knife mounting frame 19 and the sliding plate 20 will be at the same height at the same time.

[0037] The downward movement height of the movable plate 7 will drive the lifting height of the adjustment plate 15 , so that the cutting knife can adjust the cutting depth according to the thickness of the metal body 6 .

[0038] The lead screw 10 is a forward and reverse lead screw, so that the movable plate 7 can move back and forth on the fixed frame 3.

[0039] When the movable plate 7 moves back, the adjusting column 17 at the top of the movable plate 7 will drive the limit column 30 to move upward, and make the piston rod 35 move in the adjusting cylinder 29. Under the effect of squeezing paralysis, the piston rod 35 will separate the limit block 31 from the adjusting gear 28, so as to facilitate the next bending and cutting work of the metal body 6.

[0040] See also Figure 11-13The present invention provides a technical solution: In this embodiment, extrusion plates 12 are movably installed inside both sides of the fixing frame 3, and clamping mechanisms 13 are arranged on both sides of the conveyor belt. The extrusion plates 12 are located above the clamping mechanisms 13. The clamping mechanisms 13 include a support plate 36, a first connecting column 37, a second connecting column 38, a third connecting column 39 and a clamping plate 40. The clamping plate 40 is L-shaped and contacts the side of the metal body 6. One end of the first connecting column 37 is movably connected to the second connecting column 38, and the other end of the first connecting column 37 is fixedly connected to the clamping plate 40. A sliding cavity 46 matching the first connecting column 37 is provided on the side of the clamping plate 40, and the other end of the second connecting column 38 is in sliding contact with the third connecting column 39.

[0041] In this embodiment, the support plate 36 is in a Z-shape, and the side of the support plate 36 is movably connected to the second connecting column 38. The first connecting column 37 and the third connecting column 39 both pass through the support plate 36. A limit plate 42 is fixedly installed on the outer side of the first connecting column 37. One end of the limit plate 42 is fixedly connected to a fourth compression spring 41, and the other end of the fourth compression spring 41 is fixedly connected to the side of the support plate 36. A sliding through hole 43 matching the first connecting column 37 is opened inside the support plate 36. A bevel block 44 is fixedly installed on the other end of the third connecting column 39. The bevel block 44 is in sliding contact with the extrusion plate 12. A fifth compression spring 45 is fixedly installed on the other end of the bevel block 44, and the other end of the fifth compression spring 45 is fixedly connected to the support plate 36.

[0042] When the connecting frame 8 moves downward, it will drive the extrusion plate 12 to move together. When the extrusion plate 12 moves downward, it will squeeze the bevel block 44 to both sides. The bevel block 44 drives the third connecting column 39 to move in the support plate 36. When the third connecting column 39 moves, it can drive the first connecting column 37 to slide in the sliding through hole 43 in the support plate 35 through the second connecting column 38, and the first connecting column 37 will drive the clamping plate 40 to move toward the side of the metal part body 6, and the clamping plate 40 will clamp and fix the metal part body 6.

[0043] When the first connecting column 37 drives the clamping plate 40 to move toward the side of the metal body 6, the end of the first connecting column 37 connected to the clamping plate 40 will move in the sliding cavity 46 in the clamping plate 40, and at the same time drive the clamping plate 40 to move, and the first connecting column 37 will move in the sliding through hole 43 in the support plate 36 to achieve height adjustment, preventing the first connecting column 37 from being unable to move in the support plate 36 when squeezed by the second connecting column 38.

[0044] Working principle of this embodiment: When the metal body 4 is being bent, the first fixing plate 11 on the metal body 4 will first fix the metal body 4 in the cutting direction, and before cutting, the clamping plate 34 will fix the two lateral sides of the metal body 4. By fixing the metal body 4 in multiple directions, it is ensured that the metal body 4 will not be lifted up when the metal body 4 is bent, preventing the metal body 4 from being unable to bend, and ensuring that the metal body 4 will not move when the metal body 4 is cut, ensuring the smooth cutting work. The cutting knife can adjust the cutting depth of the cutting knife according to the thickness of the metal body 4, and a cutting groove is provided on the base plate 1 to facilitate the cutting work of the cutting knife, prevent the cutting knife from touching the base plate 1, and also prevent the cutting knife from being damaged. An air gun 21 is provided behind the cutting knife, and the air gun 21 and the cutting knife are located in the same horizontal plane. When the cutting knife is working, the air gun 21 can remove the iron filings in the cutting groove, and the protective baffle 19 can prevent the sparks generated by the cutting knife from flying, thereby protecting the staff and preventing the danger caused by the sparks.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
