Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for metal plate processing, and specifically to a correction device for cutting aluminum plates. Background Technology

[0002] Aluminum sheet cutting is a process that uses aluminum or aluminum alloy sheets as the base material. The aluminum coil is uncoiled, straightened and stably conveyed to the cutting process without deformation. Combined with CNC servo shearing, it is processed into aluminum sheets of customized size, achieving efficient and deformation-free cutting. However, when the aluminum coil is conveyed to the cutting machine, the coil is prone to shaking and deviation during the conveying process. Therefore, a correction device is needed to correct the position of the coil to ensure the accuracy of the cut aluminum sheet.

[0003] However, most existing web-aligning devices use lead screws to adjust the positions of two limiting rollers to correct the position of the coil material. After prolonged use, wear marks easily form on the surface of the limiting rollers at the contact points with the edge of the coil material, creating gaps between the coil material and the limiting rollers. This prevents the limiting rollers from effectively limiting the position of the coil material, affecting the accuracy of web alignment. Therefore, those skilled in the art have provided a web-aligning device for aluminum plate cutting to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a correction device for cutting aluminum plates 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 correction device for cutting aluminum plates includes: two L-shaped fixed frames respectively disposed at both ends of the feed inlet of a cutting machine; a horizontal plate is disposed on the top of the L-shaped fixed frames; a through groove is opened in the middle of the horizontal plate; an adjusting seat and a limiting seat are slidably disposed inside the through groove; the adjusting seat is disposed inside the limiting seat; a limiting roller is rotatably mounted on the lower end face of the adjusting seat; the limiting roller is upright at the feed inlet of the cutting machine; a spring is disposed between the side wall of the limiting seat near the adjusting seat and the side wall of the adjusting seat; a threaded rod is rotatably mounted on the side wall of the limiting seat away from the adjusting seat; the other end of the threaded rod passes through the horizontal plate and is threaded inside it; and the limiting seat can slide in the through groove according to the rotation of the threaded rod.

[0007] Preferably, the inner walls on both sides of the through groove are provided with sliding grooves, and the outer ends of the adjusting seat and the limiting seat are respectively provided with a first slider and a second slider, and the first slider and the second slider are slidably installed inside the sliding groove.

[0008] Preferably, the height of the adjusting seat and the limiting seat is the same as the depth of the through groove, and the upper and lower ends of the adjusting seat and the limiting seat are flush with the upper and lower ends of the horizontal plate, respectively.

[0009] Preferably, one end of the limiting roller is provided with a rotating shaft, and the other end of the rotating shaft is rotatably mounted on the lower end face of the adjusting seat.

[0010] Preferably, a first threaded hole is provided on the outer wall of the horizontal plate at the position corresponding to the threaded rod, and the threaded rod is threadedly installed inside the first threaded hole and extends to the outside of the horizontal plate.

[0011] Preferably, the outer wall of the threaded rod is provided with limit nuts on both the inner and outer sides of the horizontal plate. The limit nuts are threadedly installed on the outer wall of the threaded rod and closely attached to the inner and outer sides of the horizontal plate, and the internal thread directions of the two limit nuts are opposite.

[0012] Preferably, the outer wall of the L-shaped fixing bracket is provided with a second threaded hole at the end away from the horizontal plate. The L-shaped fixing bracket is threaded onto the outer wall of the lead screw through the second threaded hole, and the internal threads of the two second threaded holes are in opposite directions.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting an adjusting seat and a limiting seat, the position of the limiting seat can be adjusted using a threaded rod, changing the distance between the limiting seat and the adjusting seat. This allows the spring to be in a compressed or extended state, thereby adjusting the clamping force of the limiting roller on the roll material. This not only avoids the problem of the roll material not being able to be conveyed due to excessive clamping force of the limiting roller, but also ensures that the adjusting seat, under the action of the spring force, drives the limiting roller to always press tightly against both sides of the roll material, limiting the position of the roll material. This prevents the situation where gaps exist between the surface of the worn limiting roller and the edge of the roll material, which would prevent the roll material from being unable to be limited in position, thus ensuring the stability of the roll material conveying and improving the correction accuracy.

[0021] Combination Figures 1-4 As shown, a correction device for cutting aluminum plates includes: two L-shaped fixing frames 1 respectively disposed at both ends of the feed inlet of the cutting machine; a horizontal plate 11 is disposed on the top of the L-shaped fixing frame 1; a through groove 101 is opened at the middle position of the horizontal plate 11; an adjusting seat 12 and a limiting seat 14 are slidably disposed inside the through groove 101; the adjusting seat 12 is disposed inside the limiting seat 14; a limiting roller 13 is rotatably mounted on the lower end face of the adjusting seat 12; the limiting roller 13 is erected at the feed inlet of the cutting machine; a spring 15 is disposed between the side wall of the limiting seat 14 near the adjusting seat 12 and the side wall of the adjusting seat 12; a threaded rod 16 is rotatably mounted on the side wall of the limiting seat 14 away from the adjusting seat 12; the other end of the threaded rod 16 passes through the horizontal plate 11 and is threaded inside it; and the limiting seat 14 can slide in the through groove 101 according to the rotation of the threaded rod 16.

[0022] In one embodiment, the inner walls of both sides of the through groove 101 are provided with sliding grooves 102. The outer ends of the adjusting seat 12 and the limiting seat 14 are respectively provided with a first slider 121 and a second slider 141. The first slider 121 and the second slider 141 are slidably installed inside the sliding groove 102. By cooperating with the sliding groove 102, the adjusting seat 12 and the limiting seat 14 slide in the through groove 101, changing the distance between the limiting seat 14 and the adjusting seat 12, so that the spring 15 between the limiting seat 14 and the adjusting seat 12 is in a compressed or extended state, thereby achieving the purpose of adjusting the clamping force of the limiting roller 13 on the roll material.

[0023] In one embodiment, the height of the adjusting seat 12 and the limiting seat 14 is the same as the depth of the through groove 101, and the upper and lower ends of the adjusting seat 12 and the limiting seat 14 are respectively flush with the upper and lower ends of the horizontal plate 11; this allows the limiting roller 13 installed on the lower end face of the adjusting seat 12 to be located below the horizontal plate 11 and not in contact with the horizontal plate 11, preventing interference between the limiting roller 13 and the horizontal plate 11, and ensuring the position adjustment of the limiting roller 13.

[0024] In one embodiment, one end of the limiting roller 13 is provided with a rotating shaft 131, and the other end of the rotating shaft 131 is rotatably mounted on the lower end face of the adjusting seat 12; this allows the limiting roller 13 to rotate along with the conveying of the roll material, preventing the limiting roller 13 from rubbing against the edge of the roll material, reducing the wear of the limiting roller 13, and extending the service life of the limiting roller 13. Moreover, the limiting roller 13, rotating below the adjusting seat 12 via the rotating shaft 131, can also play an auxiliary conveying role.

[0025] In one embodiment, a first threaded hole 103 is provided on the outer wall of the horizontal plate 11 at a position corresponding to the threaded rod 16. The threaded rod 16 is threadedly installed inside the first threaded hole 103 and extends to the outside of the horizontal plate 11. The threaded rod 16 can be screwed in the first threaded hole 103 to extend into the through groove 101 and push the limiting seat 14 connected thereto to slide in the through groove 101, thereby achieving the function of adjusting the position of the limiting seat 14.

[0026] In one embodiment, limit nuts 17 are provided on both the inner and outer sides of the outer wall of the threaded rod 16 and the horizontal plate 11. The limit nuts 17 are threaded onto the outer wall of the threaded rod 16 and are tightly attached to the inner and outer sides of the horizontal plate 11, and the internal thread directions of the two limit nuts 17 are opposite. The threaded rod 16 can be tightened by two limit nuts 17 with opposite thread directions to limit the position of the threaded rod 16, prevent the threaded rod 16 from rotating, avoid the displacement of the limit seat 14 due to the rotation of the threaded rod 16, and ensure the stability of the limit seat 14 after the position is adjusted.

[0027] In one embodiment, the outer wall of the L-shaped fixing bracket 1 is provided with a second threaded hole 104 at the end away from the horizontal plate 11. The L-shaped fixing bracket 1 is threaded onto the outer wall of the lead screw 2 through the second threaded hole 104, and the internal threads of the two second threaded holes 104 are opposite in direction. The lead screw 2 can be driven to rotate by an external motor, which will cause the two L-shaped fixing brackets 1, which are fitted onto the outer wall of the lead screw 2 through the second threaded hole 104, to move towards the edge of the coil material. The coil material is clamped between the two limiting rollers 13 for limiting, preventing the position of the coil material entering the cutting machine from shifting, and improving the quality of the cut aluminum plate.

[0028] The working principle of this utility model is as follows: When correcting the deviation of the roll material entering the cutting machine, an external motor can be used to drive the lead screw 2 to rotate, which in turn drives the two L-shaped fixing brackets 1, which are fitted onto the outer wall of the lead screw 2 through the second threaded hole 104, to move towards the edge of the roll material. This clamps the roll material between the two limiting rollers 13. Under the reaction force of the roll material, the two limiting rollers 13 drive the adjusting seat 12 to slide in the through groove 101 and press the spring 15 tightly. Then, under the elastic force of the spring 15, the adjusting seat 12 drives the limiting rollers 13 to always press tightly against both sides of the roll material, limiting the position of the roll material and avoiding the limiting rollers from being worn out. The gap between the surface of roller 13 and the edge of the roll material prevents the roll material from being positioned incorrectly, thus ensuring the stability of the roll material conveying and improving the correction accuracy. Furthermore, the position of the limit seat 14 is adjusted by using the threaded rod 16, changing the distance between the limit seat 14 and the adjusting seat 12. This allows the spring 15 between the limit seat 14 and the adjusting seat 12 to be in a compressed or extended state, achieving the purpose of adjusting the clamping force of the limit roller 13 on the roll material. It also avoids the problem of the roll material not being conveyed due to excessive clamping force of the limit roller 13, ensuring the smooth operation of the roll material conveying.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
