Description

Technical Field

[0001] This invention relates to the field of aluminum plate cutting technology, specifically a high-stability cutting device for multi-size aluminum plates. Background Technology

[0002] In the industrial production field, aluminum sheets are widely used in aerospace, building curtain walls, rail transportation and other industries due to their excellent properties such as light weight, high strength and corrosion resistance. As industrial production continues to increase its requirements for the processing precision and efficiency of aluminum sheets, the cutting and processing of aluminum sheets has become a key link in the production process.

[0003] Existing aluminum plate cutting devices still have many shortcomings in practical applications. Aluminum plate cutting is divided into manual cutting and automatic cutting. Although the cutting efficiency of automatic cutting is several times that of manual cutting, automatic cutting devices have the common problem of cumbersome debugging. Especially when cutting aluminum plates of different widths, pre-debugging needs to be done every time. In addition, automatic cutting machines mostly use a single clamping structure, which makes it difficult to initially fix the aluminum plate from above before fixing the side of the aluminum plate. This can easily lead to a decrease in cutting quality and affect cutting efficiency and cutting stability.

[0004] In terms of equipment protection, after the existing cutting device finishes cutting, the aluminum plate often stays directly near the cutting area. When the cutting device resets, it is easy to generate friction with the surface of the aluminum plate, which will not only scratch the surface of the aluminum plate, but also wear down the cutting tool, shorten the service life of the equipment, and increase maintenance costs.

[0005] In view of the shortcomings of the existing technology, there is an urgent need for a high-stability cutting device for multi-size aluminum plates that can solve problems such as unstable clamping, insufficient equipment protection, and low cutting efficiency. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a high-stability cutting device for multi-size aluminum plates. The present invention has an ingenious structure, focuses on practicality, and effectively solves the technical problems of poor cutting stability and poor cutting efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-stability cutting device for multi-size aluminum plates includes a mounting housing, a conveying overlap platform, and a feeding and placing rack, wherein a multi-level locking assembly is provided above the feeding and placing rack;

[0009] The multi-stage locking assembly includes a side positioning push rod fixedly installed above the feed placement frame. The side positioning push rod is fixedly installed with two sliding sleeves. Multiple sliding plates are slidably connected inside the sliding sleeves. A rear auxiliary plate is fixedly installed on one end face of each of the multiple sliding plates. Two connecting tension springs are fixedly installed between the sliding sleeves and the rear auxiliary plates. A separation clamping plate is fixedly installed on the other end face of each of the multiple sliding plates.

[0010] Preferably, each of the sliding sleeves is slidably connected to a locking plate that can engage with each set of sliding plates.

[0011] Preferably, each of the sliding sleeves is slidably connected to a sliding frame, a pushed plate is fixedly installed on one side of each locking plate, a pushing block that can contact the pushed plate is slidably connected inside each sliding frame, and a reset spring is fixedly installed between each pushed plate and the sliding frame.

[0012] Preferably, a primary connecting rod is fixedly installed on one end face of each push block, and a secondary connecting rod is fixedly installed on one side of each separation clamping plate. A primary sleeve and a secondary sleeve capable of threaded connection are respectively fitted onto the surface of each primary connecting rod and the secondary connecting rod.

[0013] Preferably, a knife protection assembly is provided on the top of the mounting housing.

[0014] Preferably, the tool protection assembly includes a rear overlap block and a front overlap block that are slidably connected to the mounting housing.

[0015] The present invention has the following technical advantages.

[0016] 1. This invention, through the linkage of components such as the side positioning push rod, sliding sleeve, sliding plate, and separation clamping plate, combined with the tension of the connecting spring and the locking function of the locking plate, can achieve side separation clamping of stacked aluminum plates of different widths, and simultaneously cut multiple sets of aluminum plates of different widths to ensure cutting efficiency. At the same time, by adjusting the height of the sliding frame and using the threaded connection between the first-stage and second-stage sleeves for positioning, it can adapt to aluminum plates of different thicknesses, avoid clamping offset, and ensure clamping stability. Furthermore, the feed amount of the side positioning push rod can be pre-fixed according to the top aluminum plate, further improving clamping stability.

[0017] 2. The material ejector pusher moves the rear and front overlapping blocks, which can move them away from the cutting equipment after the aluminum plate is cut. This effectively avoids excessive friction between the cutting equipment and the aluminum plate when the equipment is reset, providing good protection for the cutting equipment and extending its service life.

[0027] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 6 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0028] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] This invention is a high-stability cutting device for multi-size aluminum plates, including a mounting housing 1, a conveying overlap platform 3 fixedly mounted on the mounting housing 1, and a feeding placement rack 5 slidably connected to the conveying overlap platform 3. The feeding placement rack 5 is provided with a multi-level locking assembly above it.

[0030] The multi-stage locking assembly includes a side positioning push rod 11 fixedly installed above the feed placement frame 5. The side positioning push rod 11 is connected to the power supply and the controller. Two symmetrically distributed sliding sleeve frames 28 are fixedly installed on the output end face of the side positioning push rod 11. The sliding sleeve frame 28 is a rectangular stainless steel frame with one side through. Multiple sliding plates 36 are slidably connected inside the sliding sleeve frame 28. The sliding plate 36 is a stainless steel frame with multiple evenly distributed teeth machined on one side. A rear auxiliary plate 26 is fixedly installed on one end face of each of the multiple sliding plates 36. The rear auxiliary plate 26 is a rectangular stainless steel frame. Two symmetrically distributed connecting tension springs 27 are fixedly installed between the sliding sleeve frame 28 and the rear auxiliary plate 26.

[0031] Separation clamping plates 37 are fixedly installed on the other end face of multiple sliding plates 36. The separation clamping plates 37 are composed of a rectangular stainless steel metal frame and a rubber pad connected to the end face of the frame. Each sliding sleeve frame 28 is slidably connected with a locking plate 35 that can engage with multiple sets of sliding plates 36. The locking plate 35 is a rectangular metal frame with teeth on one side that can engage with the sliding plate 36.

[0032] Each sliding sleeve 28 has two symmetrically distributed sliding grooves 29, and each sliding groove 29 has a sliding block 30 slidably connected in it. The same sliding frame 41 is fixedly installed on one side of each pair of sliding blocks 30. Each locking plate 35 has a push plate 33 fixedly installed on one side. The push plate 33 is a structure composed of a cylindrical and a disc stainless steel metal frame.

[0033] Each sliding frame 41 has a sliding block 32 that can contact the pushed plate 33. The push block 32 is a trapezoidal stainless steel block. A reset spring 34 is fixedly installed between each pushed plate 33 and the sliding frame 41.

[0034] Each push block 32 has a primary connecting rod 31 fixedly installed on one end face, and each separation clamping plate 37 has a secondary connecting rod 38 fixedly installed on one side. Each primary connecting rod 31 and secondary connecting rod 38 has a primary sleeve 40 and a secondary sleeve 39 that can be threadedly connected respectively on their surfaces.

[0035] In this embodiment, before side clamping of aluminum plates stacked on one side with different widths, multiple aluminum plates of different sizes are placed from bottom to top in descending order of size. Based on the thickness of the multiple plates, the sliding frame 41 is directly pulled to slide within the sliding sleeve 28 to adjust the specific height of the sliding frame 41. After the height of the sliding frame 41 is adjusted, the secondary sleeve 39 on the surface of the secondary connecting rod 38 is pulled out, and at the same time, the primary sleeve 40 on the surface of the primary connecting rod 31 is pulled out. The secondary sleeve 39 and the primary sleeve 40 are threaded together to position the height of the sliding frame 41.

[0036] When clamping aluminum plates of different widths from the side, the drive side positioning push rod 11 drives the sliding sleeve 28 and sliding plate 36 forward. When the separation clamping plate 37 contacts the aluminum plate, the lower separation clamping plate 37 is first squeezed by the wider aluminum plate. When the separation clamping plate 37 corresponding to the height of the first-level connecting rod 31 is pushed, this separation clamping plate 37 will push the second-level connecting rod 38 to move in the opposite direction. At this time, the side positioning push rod 11 continues to advance, the second-level connecting rod 38 moves and pushes the first-level connecting rod 31 and the push block 32. The inclined surface of the push block 32 squeezes the pushed plate 33 and the locking plate 35 to move towards the sliding plate 36. The locking plate 35 moves a distance to achieve the purpose of locking all the sliding plates 36. At this time, the separation clamping plate 37 above the first-level connecting rod 31 limits the upper surface of the uppermost aluminum plate, and the multiple separation clamping plates 37 below limit the aluminum plates of different widths respectively.

[0037] The feed amount of the side positioning push rod 11 is adjusted accordingly based on the width of the uppermost aluminum plate.

[0038] As an example, a tool protection assembly is provided on the top of the mounting housing 1. The tool protection assembly includes a rear overlapping block 21 and a front overlapping block 15 that are slidably connected to the mounting housing 1. Both the rear overlapping block 21 and the front overlapping block 15 are long rectangular stainless steel metal blocks. Two evenly distributed ejector push rods 23 are fixedly installed on the inner side of the mounting housing 1, with their output ends fixed to one side of the rear overlapping block 21 and the front overlapping block 15, respectively. The ejector push rods 23 are connected to the power supply and the controller.

[0039] In this embodiment, after the aluminum plate is cut between the front overlapping block 15 and the rear overlapping block 21, the two ejector push rods 23 can be controlled to retract simultaneously and drive the aluminum plates on both sides away from the cutting equipment, so as to prevent excessive friction between the cutting equipment and the aluminum plate when the cutting equipment is reset, thus protecting the cutting equipment.

[0040] As an example, an upper surface clamping assembly is provided above the mounting housing 1. The upper surface clamping assembly includes an upper clamping plate 24 disposed above the mounting housing 1 and a front clamping plate 14 and a rear clamping plate 19 slidably connected above the mounting housing 1. The upper clamping plate 24, the front clamping plate 14 and the rear clamping plate 19 are all structures with rubber pads added to the clamping surfaces.

[0041] A conveyor chain 4 is fixedly installed on the top of the housing 1. An upper adjustable frame 9 is fixedly installed on one side of the conveyor chain 4. A clamping frame 6 is fixedly installed on one side of the upper adjustable frame 9. The clamping frame 6 is fixedly installed above the feeding rack 5. The feeding rack 5 is an L-shaped stainless steel metal plate. A rolling wheel 25 that rests on the conveyor overlap table 3 is rotatably connected to one side of the feeding rack 5.

[0042] An upper positioning push rod 7 is fixedly installed above the clamping and fixing frame 6. The upper positioning push rod 7 is connected to the power supply and the controller. The output shaft of the upper positioning push rod 7 passes through the bottom end face of the upper adjustable frame 9 and is fixedly installed with an upper clamping plate 24. A first-stage upper sliding rod 8 with its bottom end fixedly installed above the upper clamping plate 24 is slidably connected between the clamping and fixing frame 6 and the upper adjustable frame 9.

[0043] A front mounting bracket 13 is fixedly installed on the top of the housing 1. The front mounting bracket 13 is an L-shaped stainless steel metal plate. A front cutting positioning push rod 12 is fixedly installed on the top of the front mounting bracket 13. The front cutting positioning push rod 12 is connected to the power supply and the controller. The bottom end of the output of the front cutting positioning push rod 12 is fixedly installed on the top of the front clamping plate 14. A front sliding rod 17 is slidably connected inside the front mounting bracket 13 and fixedly installed on the upper surface of the front clamping plate 14.

[0044] A control mounting bracket 10 is fixedly installed on the top of the housing 1. The control mounting bracket 10 is provided with a rear cutting positioning push rod 16. The rear cutting positioning push rod 16 is connected to the power supply and the controller. The lower output end face of the rear cutting positioning push rod 16 is fixedly installed on the top of the rear clamping plate 19. A rear sliding rod 18 with its lower end face fixedly installed on the upper surface of the rear clamping plate 19 is slidably connected in the control mounting bracket 10.

[0045] In this embodiment, when clamping and fixing the upper surface of the aluminum plate, the upper positioning push rod 7, the front cutting positioning push rod 12 and the rear cutting positioning push rod 16 can be driven to work, which respectively drive the upper clamping plate 24, the front clamping plate 14 and the rear clamping plate 19 to descend, and squeeze and fix the upper surface of the aluminum plate.

[0046] As an example, the mounting housing 1 is provided with an adjustable cutter 22. The adjustable cutter 22 consists of an electric push rod connected to a lifting mounting frame, a saw blade rotatably connected in the lifting mounting frame, and a drive motor installed on one side of the lifting mounting frame with its output shaft surface connected to the saw blade. The electric push rod and the drive motor are both connected to a power supply and a controller.

[0047] In this embodiment, when cutting the aluminum plate, the drive motor can be controlled to work, driving the saw blade to rotate, and then the electric push rod can work to drive the saw blade to rise, thereby cutting and separating the aluminum plate above.

[0048] As one embodiment, four symmetrically distributed support legs 2 are fixedly installed on the lower part of the mounting housing 1, and a material placement plate 20 is fixedly installed on the upper part of the mounting housing 1.

[0049] Working principle:

[0050] S1. First, aluminum plates of different widths are placed from bottom to top in the mounting housing 1 from the conveyor overlap platform 3 according to their width. Then, the height of the sliding frame 41 is adjusted according to the thickness and width requirements of the aluminum plates, and the primary sleeve 40 is threadedly connected to the secondary sleeve 39 for positioning.

[0051] After adjusting the height of the sliding frame 41, the control side positioning push rod 11 is started to drive the sliding sleeve 28 and the sliding plate 36 forward. After the separation clamping plate 37 contacts the aluminum plate, the lower plate is squeezed and moved until the separation clamping plate 37 at the corresponding height pushes the secondary connecting rod 38, which in turn pushes the primary connecting rod 31 and the pushing block 32 to move. The inclined surface of the pushing block 32 squeezes the push plate 33, which drives the locking plate 35 and the sliding plate 36 to engage and lock, thereby fixing the side of aluminum plates of different widths and simultaneously performing a certain degree of initial clamping and limiting on the uppermost aluminum plate surface.

[0052] S2. Subsequently, the upper positioning push rod 7, the front cutting positioning push rod 12 and the rear cutting positioning push rod 16 drive the upper clamping plate 24, the front clamping plate 14 and the rear clamping plate 19 to descend respectively, and the rubber pads on their clamping surfaces press and fix the upper surface of the aluminum plate, thus completing the secondary fixation of the upper surface.

[0053] S3. Next, the drive motor in the adjustable cutter 22 drives the saw blade to rotate, and the electric push rod drives the saw blade to rise to cut and separate the clamped aluminum plate. After the cutting is completed, the ejector push rod 23 retracts, which drives the rear overlapping block 21 and the front overlapping block 15 to move away from the cutting equipment. The cut aluminum plate can then be unloaded through the unloading plate 20.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
