Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, and in particular to a flexible grinding device for metal plate processing. Background Art

[0002] Flexible grinding of metal plates is a process for surface treatment of metal plates. In this process, some special tools and techniques are usually used to achieve a relatively soft and fine grinding treatment of the metal plate. This can remove blemishes, scratches, rust, etc. on the surface of the metal plate, while making the surface smoother and flatter, and minimizing damage to the metal plate itself.

[0003] The traditional grinding method has a high degree of manual involvement, which makes it difficult to completely and evenly control the grinding force and angle, resulting in inconsistent local surface roughness. If the grinding is shallow, it is difficult to effectively eliminate flaws, scratches, rust, etc. on the surface of the metal plate, and the processing accuracy and smoothness are greatly reduced. If the grinding is excessive, it is easy to make the metal plate thinner and even affect its structural strength. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-9 , the present invention provides a technical solution:

[0032] A flexible grinding equipment for metal plate processing comprises a processing table 1, a conveyor belt 2 is arranged on the processing table 1, and a flap mechanism is arranged on the inner side of the processing table 1; the flap mechanism comprises a bottom plate 3 fixedly connected to the processing table 1, and a flip plate 4, a flip plate 2 5 and a rotating seat 7 are rotatably connected to the bottom plate 3, and connecting rods 1 8 and connecting rods 2 9 are rotatably connected at both ends of the rotating seat 7, one end of the connecting rod 1 8 is rotatably connected to one end of the flip plate 1 4, and the end of the connecting rod 2 9 away from the rotating seat 7 is rotatably connected to one end of the flip plate 2 5; one side of the processing table 1 is rotatably connected to a bracket 11 through a connecting frame 10, and a hydraulic cylinder 12 is arranged on the bracket 11, and the output end of the hydraulic cylinder 12 is rotatably connected to one end of the rotating seat 7; a lifting frame 13 is arranged at the rear side of the processing table 1, and a transverse module 14 is arranged on the lifting frame 13, and the lifting frame 13 is slidably connected to the grinding mechanism through the transverse module 14, and one end of the processing table 1 is provided with a unloading mechanism matched with the processing table 1. Preferably, the conveyor belt 2 is a belt with greater surface friction, or it can be replaced with a fixed base according to actual conditions when the plate does not need to be moved too much, in conjunction with the plate's own gravity to maintain the stability of the plate during the flexible grinding process. Due to the characteristics of flexible grinding, the force exerted on the plate is relatively small, and relying on its own gravity and a belt or base with greater friction, it is sufficient to maintain stability during the grinding process, thereby ensuring the grinding effect.

[0033] Specifically, Figure 1 , Figure 5 and Figure 6 As shown, the grinding mechanism includes a moving seat 15 connected to the transverse movement module 14, a driving motor 16 is provided inside the moving seat 15, a worm 17 is fixedly connected to the output end of the driving motor 16, a sleeve rod 18 is splinedly connected to the end of the worm 17 away from the driving motor 16, the sleeve rod 18 extends to the outside of the moving seat 15 away from the end of the worm 17 and is fixedly connected to a coaxially arranged flexible grinding head 20, and a reciprocating component matching the worm 17 is provided inside the moving seat 15. The reciprocating assembly includes a fixed frame 1 21 and a fixed frame 27 which are fixedly connected to the inner wall of the movable seat 15. The fixed frame 1 21 is rotatably connected to a worm gear 23 via a rotating shaft 22. The worm gear 23 is meshed with the worm 17. An eccentric wheel 24 is fixedly connected to the rotating shaft 22. A collar 25 is sleeved on the outer side of the eccentric wheel 24. A connecting rod 3 26 is integrally formed on the outer periphery of the collar 25. A rotating arm 28 is rotatably connected to the fixed frame 27. One end of the connecting rod 3 26 away from the collar 25 is rotatably connected to the middle part of the rotating arm 28. A snap ring 19 is provided on the sleeve rod 18. One end of the rotating arm 28 away from the fixed frame 27 cooperates with the snap ring 19. Preferably, when grinding, it is necessary to reasonably select the type of grinding head according to factors such as the material, thickness and required surface quality requirements of the plate, and then determine the grinding parameters, such as grinding pressure, speed, feed rate, etc., to ensure the ideal grinding effect and minimize the damage to the plate itself. At the same time, the wear of the grinding head itself should be paid attention to regularly, and it should be replaced when necessary to ensure the grinding effect.

[0034] Specifically, Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, the unloading mechanism includes a support frame 29 arranged at one end of the processing table 1, a stacking frame 30 is integrally formed above the support frame 29, an open cavity 43 and a notch 44 are opened at the lower end of the stacking frame 30, and a pushing assembly matching the open cavity 43 and the notch 44 is provided on the inner side of the support frame 29. The pusher assembly includes a slide bar 1 31 fixedly connected to the processing table 1, a slide sleeve 1 32 is sleeved on the slide bar 1 31, a slide bar 2 33 is fixedly connected to the lower end of the slide sleeve 1 32, a slide sleeve 2 34 is sleeved on the slide bar 2 33, a pedestal 35 is fixedly connected to the slide sleeve 2 34, a column 36 is arranged on the pedestal 35, a connecting seat 37 is rotatably connected to one side of the slide sleeve 2 34, a slide bar 3 38 is fixedly connected to the connecting seat 37, a base 39 is fixedly connected to the cross beam of the support frame 29, a drive motor 2 40 is arranged on the base 39, a rotating block 41 is fixedly connected to the output end of the drive motor 2 40, one end of the slide bar 3 38 away from the connecting seat 37 passes through the rotating block 41, a spring 42 is sleeved on the slide bar 38, and the two ends of the spring 42 are respectively in contact with the rotating block 41 and the connecting seat 37. The width of the pedestal 35 matches the notch 44, and the height of the column 36 matches the height of the open cavity 43. Preferably, the height of the open cavity 43 is the same as the height of the conveyor belt 2 on the processing table 1, or the height of the open cavity 43 is slightly higher than the height of the conveyor belt 2, so as to facilitate the entry of the plate into the conveyor belt 2. The driving motor 2 40 is preferably a servo motor. At the same time, the plates in the stacking rack 30 should not be stacked too much to avoid the situation where the plate at the bottom is inconvenient to be pushed out due to excessive pressure.

[0035] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the flip plate 1 4 and the flip plate 2 5 are provided with a crosspiece 6, and there are a plurality of crosspieces 6, and the plurality of crosspieces 6 are respectively arranged on the flip plate 1 4 and the flip plate 2 5 at equal intervals, and the middle parts of the flip plate 1 4 and the flip plate 2 5 are rotatably connected to the bottom plate 3, one end of the connecting rod 1 8 is rotatably connected to one end of the flip plate 1 4, and one end of the connecting rod 29 is rotatably connected to one end of the flip plate 2 5. Preferably, when the flip plate 1 4 flips the plate, when the flip plate 1 4 and the flip plate 2 5 are close to each other, that is, when the plate falls from the flip plate 1 4 to the flip plate 2 5, the two are in a state of being slightly tilted toward one side of the flip plate 2 5, so that the plate can better fall onto the flip plate 2 5 by its own gravity, and at the same time, the tilt angle is small, so as to avoid the plate losing support for too long, thereby achieving a perfect transfer of the plate from the flip plate 1 4 to the flip plate 2 5.

[0036] In summary, the flexible grinding equipment for metal plate processing provided by the present embodiment, when in use, firstly stacks the plates and places them in the stacking rack 30, and the bottom plate falls into the open cavity 43, and the rotating block 41 is driven to rotate by the driving motor 2 40, so that the sliding rod 38 rotates, thereby driving the sliding sleeve 2 34 to slide along the sliding rod 2 33 through the connecting seat 37, and when the sliding sleeve 2 34 reaches the highest point, that is, after contacting with the sliding sleeve 1 32, the sliding sleeve 2 34 and the sliding rod 2 33 no longer move relative to each other, and at this time, the pedestal 35 also reaches the highest point, and the height of the pedestal 35 is consistent with the notch 44, and as the driving motor 37 is driven, the sliding sleeve 2 34 and the sliding rod 2 33 are moved relative to each other. The second slide 40 continues to rotate, and the slide sleeve 2 34 and the slide sleeve 1 32 are driven to move synchronously as a whole through the slide rod 38. At this time, the slide sleeve 2 34 and the slide rod 2 33 have no relative movement, and only the slide sleeve 1 32 moves along the slide rod 1 31, driving the pedestal 35 and the column 36 to move until the column 36 contacts the side of the plate in the open cavity 43. As the driving motor 2 40 continues to rotate, the pedestal 35 and the column 36 continue to move to push the plate in the open cavity 43 onto the processing table 1, and the plate is moved to the processing area corresponding to the grinding mechanism through the conveyor belt 2, and the grinding mechanism is adjusted to the appropriate position through the lifting frame 13. The worm 17 and the sleeve rod 18 are driven to rotate by the driving motor 16, thereby driving the flexible grinding head 20 to grind the plate. The rotation of the worm 17 drives the worm wheel 23 to rotate. The rotation of the worm wheel 23 drives the eccentric wheel 24 to rotate through the rotating shaft 22, thereby driving the sleeve ring 25 to rotate eccentrically about the axis of the rotating shaft 22, and then drives the rotating arm 28 to swing back and forth through the connecting rod 3 26, thereby driving the sleeve rod 18 to move back and forth through the clamping ring 19, and driving the flexible grinding head 20 to move back and forth in the axial direction to grind the plate. When one side of the plate is polished, the flexible grinding head 20 is lifted by the lifting frame 13 The plate is moved to the top of the flip plate 4 through the conveyor belt 2, and the rotating seat 7 is driven to deflect by the hydraulic cylinder 12. The deflection of the rotating seat 7 pulls the flip plate 4 and the flip plate 2 5 to be lifted synchronously through the connecting rod 1 8 and the connecting rod 2 9. The flip plate 4 and the flip plate 2 5 with the cross piece 6 are close to each other at one end. The flip plate 4 lifts the plate and gradually approaches the flip plate 2 5 until the plate falls onto the flip plate 2 5, and then the rotating seat 7 is driven to deflect in the opposite direction by the hydraulic cylinder 12, so that the flip plate 4 and the flip plate 2 5 fall and reset, completing the flipping of the plate, and then the other side of the plate is polished by the polishing mechanism.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
