[0002] There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing. The market for auto parts is getting bigger and bigger. The auto repair market is also getting bigger and bigger. Repairs often require bending metal sheets for auto parts. Therefore, there is a great need for automotive metal sheet bending processing equipment.

[0003] When existing automobile metal sheet bending processing equipment bends metal sheets, the bending knife will be subjected to a large impact force when it impacts the metal sheet under the drive of the hydraulic cylinder. The existing buffer structure is only a simple buffering and shock absorption, and does not have a limit to prevent offside function. As a result, when the bending knife just punches the metal sheet, the buffer structure begins to buffer the impact force of the bending knife, thereby reducing the impact force of the bending knife on the metal sheet.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The automobile sheet metal bending processing equipment is provided with friction plates, friction rings and gears. The hydraulic cylinder drives the pressure plate to move downward, and the pressure plate drives the bending knife to move downward. The downward-moving bending knife punches and bends the metal sheets on the first connecting plate and the second connecting plate. When the bending knife punches the metal sheets to a certain extent, the hydraulic column will contract. The impact force generated at this time drives the insertion rod and the piston to move upward. During the upward movement of the piston, the air inside the sleeve is compressed into the cylinder through the air outlet pipe. The increased air pressure in the cylinder pushes the movable rod toward the friction ring, so that The friction plate fits the surface of the friction ring. When the pressure plate moves downward, the gear rotates along the tooth groove of the side wall of the slide rod. Since the friction plate fits the surface of the friction ring, the downward pressure on the pressure plate can be converted into friction force, thereby playing a role in alleviating the impact force. The more the pressure plate moves downward, the higher the air pressure in the cylinder, and the higher the friction between the friction plate and the friction ring, thereby alleviating the impact force on the bending knife and avoiding buffering the impact force of the bending knife as soon as the bending knife punches the metal sheet, thereby reducing the impact force of the bending knife on the metal sheet.

[0026] like Figures 1 to 9 As shown, the automotive sheet metal bending processing equipment of this embodiment includes a base 1, a bracket 2 is connected to the top of the base 1, the bracket 2 is an inverted U shape, a hydraulic cylinder 3 is installed on the top of the upper part of the bracket 2, the bottom end of the hydraulic cylinder 3 extends to the inside of the bracket 2, and two slide bars 4 are connected between the bottom end of the upper part of the bracket 2 and the top end of the base 1. The outer surfaces of the two slide bars 4 are jointly provided with a pressure plate 5, and the pressure plate 5 is connected to the extended end of the hydraulic cylinder 3. Both sides of the bottom end of the pressure plate 5 are connected to a sleeve 6, a piston 8 is movably connected inside the sleeve 6, and the bottom end of the piston 8 is connected to a plug rod 7, the bottom end of the insertion rod 7 extends to the outside of the sleeve 6, and the two extension ends of the insertion rod 7 are commonly connected to the bending knife 17. The surface of one side of the upper part of the sleeve 6 is connected to the air outlet pipe 9, and one end of the air outlet pipe 9 is connected to the cylinder 10. The output end of the cylinder 10 is connected to the movable rod 11, and one end of the movable rod 11 is connected to the friction plate 12. A hydraulic column 18 is connected between the pressure plate 5 and the bending knife 17. The pressure plate 5 is driven downward by the hydraulic cylinder 3, and the pressure plate 5 drives the bending knife 17 to move downward. The downward moving bending knife 17 is on the first connecting plate 25 and the second connecting plate 26. The metal sheet on it is punched and bent. When the bending knife 17 punches the metal sheet to a certain extent, the hydraulic column 18 will shrink. The impact force generated at this time drives the insertion rod 7 to move upward together with the piston 8. During the upward movement of the piston 8, the air inside the sleeve 6 is compressed into the cylinder 10 through the outlet pipe 9. The air pressure in the cylinder 10 increases and pushes the movable rod 11 toward the friction ring 15, so that the friction plate 12 fits the surface of the friction ring 15. When the pressure plate 5 moves downward, the gear 14 moves along the tooth groove of the side wall of the slide rod 4. Rotation, due to the surface fit between the friction plate 12 and the friction ring 15, the downward pressure on the pressure plate 5 can be converted into friction force, thereby playing a role in alleviating the impact force. The more the pressure plate 5 moves downward, the higher the air pressure in the cylinder 10, and the higher the friction between the friction plate 12 and the friction ring 15. This can alleviate the impact force on the bending knife 17 and avoid buffering the impact force of the bending knife 17 as soon as the bending knife 17 punches the metal sheet, thereby reducing the impact force of the bending knife 17 on the metal sheet.

[0027] Both sides of the bottom end of the pressure plate 5 are connected with mounting parts 13, and the bottom end of the mounting part 13 is rotatably connected to a rotating shaft 16, through which the gear 14 can be rotated; the outer surface of the rotating shaft 16 is sleeved with a gear 14, and the gear 14 is meshed with the surface of one side of the slide rod 4, and the surface of the slide rod 4 close to the gear 14 is provided with a tooth groove, and the teeth of the gear 14 close to the slide rod 4 extend into the tooth groove. The outer surface of the rotating shaft 16 at the front end of the gear 14 is sleeved with a friction ring 15, and the friction plate 12 is in contact with the friction ring 15. The friction force between the friction plate 12 and the friction ring 15 is used to reduce the impact on the bending knife 17. The force is relieved; the top of the base 1 inside the two slide rods 4 is connected to two fixed blocks 19, and a slide groove 20 is opened at the top of the fixed block 19. A threaded rod 21 is rotatably connected inside the slide groove 20. The front and rear ends of the outer surface of the threaded rod 21 are provided with opposite threads. One end of the threaded rod 21 extends to the outside of the rear end of the fixed block 19. The extended end of the threaded rod 21 is connected to a handwheel 22, and the handwheel 22 drives the threaded rod 21 to rotate forward or reverse; the front and rear ends of the outer surface of the threaded rod 21 are both threadedly connected to a movable block 23, and the top of the movable block 23 extends to the outside of the fixed block 19. The movable block 23 extends The ends are connected with an adjusting block 24, and the upper parts of the opposite surfaces of the two adjusting blocks 24 are respectively hinged with a first connecting plate 25 and a second connecting plate 26. The two movable blocks 23 are driven by the threaded rod 21 to move relative or oppositely. The two movable blocks 23 respectively drive the two adjusting blocks 24 to move relative or oppositely. By adjusting the spacing between the two adjusting blocks 24, the angle between the first connecting plate 25 and the second connecting plate 26 is adjusted; a slot 27 is provided at the rear end of the first connecting plate 25 at the connection between the first connecting plate 25 and the second connecting plate 26, and a rotating rod 29 is rotatably connected inside the slot 27. The first connecting plate The front end of the second connecting plate 26 at the connection between the first connecting plate 25 and the second connecting plate 26 is connected with an insert block 28, which extends into the inside of the slot 27, and the extended end of the insert block 28 is sleeved with the rotating rod 29, so that the first connecting plate 25 and the second connecting plate 26 can be rotated through the rotating rod 29; both sides of the rear end of the first connecting plate 25 are threadedly connected with bolts 30, and one end of the bolt 30 extends into the inside of the rotating rod 29. When the angle between the first connecting plate 25 and the second connecting plate 26 is adjusted, the two bolts 30 are inserted into the first connecting plate 25 and the rotating rod 29, so that the rotating rod 29 cannot rotate.

[0028] The method of using this embodiment is as follows: the electrical components appearing in this application are all connected to an external power supply when in use and are equipped with corresponding controllers. First, the threaded rod 21 is driven to rotate forward and backward by the hand wheel 22, and the threaded rod 21 drives the two movable blocks 23 to move relative or oppositely. The two movable blocks 23 respectively drive the two adjusting blocks 24 to move relative or oppositely. By adjusting the distance between the two adjusting blocks 24, the angle between the first connecting plate 25 and the second connecting plate 26 is adjusted, and thus the bending angle of the metal sheet can be adjusted. When the angle between the first connecting plate 25 and the second connecting plate 26 is adjusted, the two bolts 30 are inserted into the first connecting plate 25 and the rotating rod 29 so that the rotating rod 29 cannot rotate, thereby fixing the angle between the first connecting plate 25 and the second connecting plate 26. Then, the metal sheet to be bent is placed on the first connecting plate 25 and the second connecting plate 26, and the pressure plate 5 is driven downward by the hydraulic cylinder 3. The pressure plate 5 drives the bending knife 17 to move downward, and the downward moving bending knife 17 presses the first connecting plate 25 and the second connecting plate 2 6 is punched and bent. When the bending knife 17 punches the metal sheet to a certain extent, the hydraulic column 18 will shrink. The impact force generated at this time drives the insertion rod 7 to move upward together with the piston 8. During the upward movement of the piston 8, the air inside the sleeve 6 is compressed into the cylinder 10 through the outlet pipe 9. The air pressure in the cylinder 10 increases and pushes the movable rod 11 toward the friction ring 15, so that the friction plate 12 fits the surface of the friction ring 15. When the pressure plate 5 moves downward, the gear 14 moves along the gear of the side wall of the slide rod 4. The groove rotates, and since the surface of the friction plate 12 and the friction ring 15 fit together, the downward pressure on the pressure plate 5 can be converted into friction force, thereby playing a role in alleviating the impact force. The more the pressure plate 5 moves downward, the higher the air pressure in the cylinder 10, and the higher the friction between the friction plate 12 and the friction ring 15, thereby alleviating the impact force on the bending knife 17 and avoiding buffering the impact force of the bending knife 17 as soon as the bending knife 17 punches the metal sheet, thereby reducing the impact force of the bending knife 17 on the metal sheet.
