Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically a sheet metal conveying mechanism for metal processing. Background Technology

[0002] In the field of automated steel plate processing, the mainstream plate conveying methods are currently roller conveyors and belt conveyors. Roller conveyors rely on the friction of spaced rotating rollers to drive the steel plate. The hard roller surfaces make point-to-line contact with the steel plate, which can easily cause indentations and scratches on the surface of high-value steel plates (such as mirror-finished plates and color-coated plates), and can also easily cause sagging deformation in the middle of thin plates. Although belt conveyors can provide surface support, the continuous friction between the conveyor belt and the surface of the steel plate still poses a risk of scratches.

[0003] Both of these traditional methods have two common drawbacks: first, they are both contact-based mechanical drives, which cannot fundamentally avoid physical damage to the surface of the steel plate; second, they both rely on friction, which can easily cause slippage and poor conveying stability when conveying steel plates with smooth surfaces or coated with oil film. Utility Model Content

[0004] The purpose of this invention is to provide a sheet metal conveying mechanism for metal processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sheet metal conveying mechanism for metal processing includes a conveying seat and a magnetic traction mechanism. The conveying seat includes a frame, connecting beams, and a sliding plate. There are two frames, which are fixedly connected by two symmetrically arranged connecting beams. A sliding plate is also provided between the two frames, with its two sides fixedly connected to the sides of the two frames respectively. The sliding plate has two symmetrically arranged elongated holes. The magnetic traction mechanism is connected to the connecting beams. The magnetic traction mechanism includes a fixed plate, sliding rods, a servo motor, a lead screw, a nut block, and electromagnetic chucks. Fixed plates are fixedly connected to the upper surfaces of both connecting beams. The two fixed plates are fixedly connected by two symmetrically arranged sliding rods. A servo motor is mounted on the side of one of the fixed plates. The output end of the servo motor is fixedly connected to a lead screw via a coupling. The other end of the lead screw is rotatably connected to the side of the other fixed plate. A nut block is threaded onto the lead screw and slidably mounted on the two sliding rods. Two symmetrically arranged electromagnetic chucks are mounted on the upper surface of the nut block.

[0007] As a further embodiment of this utility model, the material of the skateboard is a high molecular weight polyethylene board.

[0008] As a further embodiment of this utility model: the lead screw is arranged in parallel with the two slide rods.

[0009] As a further embodiment of this invention, the lead screw is a ball screw.

[0010] As a further embodiment of this utility model: both sides of the fixing plate are fixedly connected to the upper surface of the connecting beam by ribs.

[0011] As a further embodiment of this utility model: the two electromagnetic chucks are respectively located below the two elongated holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Because the driving force of this invention comes from non-contact magnetic force, the steel plate only contacts the smooth sliding plate surface during the entire conveying process, completely avoiding the point and line contact indentations of roller conveyors and the friction scratches of belt conveyors, thus improving the conveying quality of the plate. The steel plate is supported by the sliding plate during the entire conveying process, fundamentally eliminating the sagging deformation caused by suspension. Furthermore, the driving force comes from a stable and reliable electromagnetic attraction, which is much greater than the traditional friction force and is not weakened by the oil film on the surface of the steel plate, thereby ensuring the stability of the conveying process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 In this embodiment of the present invention, a sheet metal conveying mechanism for metal processing includes a conveying seat and a magnetic traction mechanism.

[0020] refer to Figure 1 , Figure 2 and Figure 3 As shown, the conveyor seat includes a frame 1, a connecting beam 2, and a sliding plate 3. There are two frames 1, which are fixedly connected by two symmetrically arranged connecting beams 2. A sliding plate 3 is also provided between the two frames 1. The two sides of the sliding plate 3 are fixedly connected to the sides of the two frames 1 respectively. The sliding plate 3 has two symmetrically arranged elongated holes 4. A magnetic traction mechanism is connected to the connecting beam 2. The magnetic traction mechanism includes a fixed plate 5, a sliding rod 7, a servo motor 8, a lead screw 9, a nut block 10, and an electromagnetic chuck 11. The upper surfaces of the two connecting beams 2 are fixedly connected to the fixed plates 5. The two fixed plates 5 are fixedly connected by two symmetrically arranged sliding rods 7. A servo motor 8 is installed on the side of one of the fixed plates 5. The output end of the servo motor 8 is fixedly connected to the lead screw 9 through a coupling. The other end of the lead screw 9 is rotatably connected to the side of the other fixed plate 5. A nut block 10 is threaded on the lead screw 9. The nut block 10 is slidably sleeved on the two sliding rods 7. Two symmetrically arranged electromagnetic chucks 11 are installed on the upper surface of the nut block 10.

[0021] It should be noted that when a steel plate needs to be transported, the electromagnetic chuck 11 located below the device is energized, generating a strong vertical magnetic field. The magnetic lines of force pass through the pre-set elongated hole 4 on the slide plate 5, firmly adsorbing the steel plate above it. Then, the servo motor 8 is started, and the servo motor 8 drives the rotation of the lead screw 9, causing the nut block 10 to move horizontally along the slide rod 7, driving the electromagnetic chuck 11 to move smoothly along the direction of the elongated hole 4. Since the steel plate has been magnetically adsorbed, the linear motion of the electromagnetic chuck 11 is converted into a horizontal traction force on the steel plate, causing the steel plate to slide with low resistance on the smooth surface of the slide plate 3, thereby realizing the transport. After reaching the target position, the electromagnetic chuck 11 is de-energized and demagnetized, and the steel plate is released.

[0022] It should be further explained that: because the driving force of this device comes from non-contact magnetic force, the steel plate only contacts the smooth plane of the slide plate 3 during the entire conveying process, which completely avoids the point and line contact indentation of the roller conveyor and the friction scratches of the belt conveyor, thus improving the conveying quality of the plate. The steel plate is supported by the slide plate 5 during the entire conveying process, which fundamentally eliminates the sagging deformation caused by suspension. Moreover, the driving force comes from a stable and reliable electromagnetic attraction, which is much greater than the traditional friction force and will not be weakened by the oil film on the surface of the steel plate, thereby ensuring the stability of the conveying process.

[0023] The material of the slide plate 3 is high molecular weight polyethylene board. High molecular weight polyethylene board is an engineering plastic with extremely low coefficient of friction and self-lubricating properties. Using it as the material of the slide plate 3 can minimize the sliding resistance between the steel plate and the platform during the conveying process, making traction easier and the operation more stable.

[0024] refer to Figure 2 and Figure 3As shown, the lead screw 9 and the two slide rods 7 are arranged in parallel to ensure that the movement axes of the lead screw 9 and the slide rods 7 are completely aligned, effectively preventing the nut block 10 from being subjected to additional torsional stress or radial force during movement, and avoiding phenomena such as jamming, shaking or even seizing.

[0025] The lead screw 9 is a ball screw, which has outstanding advantages such as high transmission efficiency, high positioning accuracy, small axial clearance and long service life.

[0026] refer to Figure 1 As shown, both sides of the fixing plate 5 are fixedly connected to the upper surface of the connecting beam 2 by ribs 6. The ribs 6 make the structure of the fixing plate 5 more stable.

[0027] refer to Figure 2 and Figure 3 As shown, the two electromagnetic chucks 11 are located below the two elongated holes 4, ensuring that the magnetic lines of force generated by the electromagnetic chucks 11 can pass through the elongated holes 4 with the shortest path and the least magnetic resistance, efficiently adsorbing the steel plate and maximizing the utilization of magnetic energy.

[0028] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
